Article of psychology. Methods. Psychology of sensation and perception. Psychology of memory Psychology - one of sciences about a person, its life and activity. The article of it is psychical activity of person, its psychical processes, states and properties. General psychology is science, which studies essence and general conformities to the law of origin, functioning and development of psyche. l Wilhelm Wundt The Founder of Psychology By the second half of the 1800s, the stage had been set for the emergence of psychology as a distinct scientific discipline. The leading proponent of this idea was a German physiologist named Wilhelm Wundt. l Wundt used scientific methods to study fundamental psychological processes, such as mental reaction times of response to visual or auditory stimuli. For example,Wundt tried to measure precisely how long it took a person to consciously detect the sight and sound of a bell being struck. l The first psychology research laboratory l l l A major turning point in psychology occurred in 1874, when Wundt published his landmark text, Principles of Physiological Psychology. In this book, Wundt outlined the connections between physiology and psychology. He also promoted his belief that psychology should be established as a separate scientific discipline that would use experimental methods to study mental processes A few years later, in 1879, Wundt realized that goal when he opened the first psychology research laboratory at the University of Leipzig. Many regard this event as marking the formal beginning of psychology as an experimental science The Titchener’s approach l l Titchener eventually departed from Wundt’s position and developed his own ideas on the nature of psychology. Titchener’s approach, called structuralism, became the first major school of thought in psychology. Structuralism* held that even our most complex conscious experiences could be broken down into elemental structures, or component parts, of sensations and feelings. To identify these structures of conscious thought, Titchener trained subjects in a procedure called introspection. The subjects would view a simple stimulus, such as a book, and then try to reconstruct their sensations and feelings immediately after viewing it. (In psychology, a stimulus is anything perceptible to the senses, such as a sight, sound, smell, touch or taste. They might first report on the colors they saw, then the smells, and so on, in the attempt to create a total description of their conscious experience. Functionalism The main proponent of American psychology was one of Harvard’s most outstanding teachers—William James. James had first become intrigued by the emerging science of psychology after reading one of Wundt’s articles, entitled “Recent Advances in the Field of Physiological Psychology,” in the late 1860s. In the early 1870s, James began teaching a physiology and anatomy class at Harvard University. An intense, enthusiastic teacher, James was prone to changing the subject matter of his classes as his own interests changed Gradually, his lectures came to focus more on psychology than on physiology. By the late 1870s, James was teaching classes devoted exclusively to the topic of psychology. James’s ideas became the basis of another early school of psychology, called functionalism, which stressed studying the adaptive and practical functions of human behavior. Sigmund Freud: Psychoanalysis In Vienna, Austria, a physician named Sigmund Freud was developing an intriguing theory of personality based on uncovering causes of behavior that were unconscious, or hidden from the person’s conscious awareness. Freud’s school of psychological thought, called psychoanalysis, emphasized the role of unconscious conflicts in determining behavior and personality. Freud’s psychoanalytic theory of personality and behavior was based largely on his work with his patients and on insights derived from self-analysis. Freud believed that human behavior was motivated by unconscious conflicts that were almost always sexual or aggressive in nature. Past experiences, especially childhood experiences, were thought to be critical in the formation of adult personality and behavior. According to Freud (1904), glimpses of these unconscious impulses are revealed in everyday life in dreams, memory blocks, slips of the tongue, and spontaneous humor. Freud believed that when unconscious conflicts became extreme, psychological disorders could result. John B. Watson: Behaviorism l l l Behaviorism contended that psychology should focus its scientific investigations strictly on overt behavior—observable behaviors that could be objectively measured and verified. Behaviorism is yet another example of the influence of physiology on psychology. Ivan Pavlov demonstrated that dogs could learn to associate a neutral stimulus, such as the sound of a bell, with an automatic behavior, such as reflexively salivating to food. Once an association between the sound of the bell and the food was formed, the sound of the bell alone would trigger the salivation reflex in the dog. Pavlov enthusiastically believed he had discovered the mechanism by which all behaviors were learned. In the United States, a young, dynamic psychologist named John B. Watson shared Pavlov’s enthusiasm. Watson (1913) championed behaviorism as a new school of psychology. Structuralism was still an influential perspective, but Watson strongly objected to both its method of introspection and its focus on conscious mental processes. The famous American psychologist B. F. Skinner Like Watson, Skinner believed that psychology should restrict itself to studying outwardly observable behaviors that could be measured and verified. In compelling experimental demonstrations, Skinner systematically used reinforcement or punishment to shape the behavior of rats and pigeons. l Between Watson and Skinner, behaviorism dominated American psychology for almost half a century. During that time, the study of conscious experiences was largely ignored as a topic in psychology. l Humanistic Psychology l l l Humanistic psychology was largely founded by American psychologist Rogers. Like Freud, Rogers was influenced by his experiences with psychotherapy clients. However, rather than emphasizing unconscious conflicts, Rogers emphasized the conscious experiences of his patients, including each person’s unique potential for psychological growth and self-direction. In contrast to the behaviorists, who saw human behavior as being shaped and maintained by external causes, Rogers emphasized self-determination, free will, and the importance of choice in human behaviour. Abraham Maslow l l l l l l Maslow developed a theory of motivation that emphasized psychological growth. Like psychoanalysis, humanistic psychology included not only influential theories of personality but also a form of psychotherapy. Each of the schools that we’ve described had an impact on the topics and methods of psychological research. From the founding of Wundt’s laboratory in 1879, psychology has evolved to its current status as a dynamic and multidimensional science. The ideas of Carl Rogers have been particularly influential in modern psychotherapy. Abraham Maslow’s theory of motivation emphasized the importance of psychological growth. The Scientific Method The four basic goals of psychology are to (1) describe, (2) explain, (3) predict, and (4) control or influence behavior and mental processes. l To achieve these goals, psychologists rely on the scientific method. The scientific method refers to a set of assumptions, attitudes, and procedures that guide researchers in creating questions to investigate, in generating evidence, and in drawing conclusions. l Like all scientists, psychologists are guided by the basic scientific assumption that events are lawful. When this scientific assumption is applied to psychology, it means that psychologists assume that behavior and mental processes follow consistent patterns. l Psychologists are also guided by the assumption that events are explainable. Thus, psychologists assume that behavior and mental processes have a cause or causes that can be understood through careful, systematic study. l The Scientific Method l l l In striving to discover and understand consistent patterns of behavior, psychologists are open-minded. They are willing to consider new or alternative explanations of behavior and mental processes. However, their open-minded attitude is tempered by a healthy sense of scientific skepticism. That is why psychologists critically evaluate the evidence for new findings, especially those that seem contrary to established knowledge. And, in promoting new ideas and findings, psychologists are cautious in the claims they make. General psychology studies: l l l - structure of psychical activity of man and basic conformities to the law of motion of psychical processes (feeling and perception, memory, attention, thought and intellect, emotions and volitional activity, consciousness, selfconsciousness, subconscious and irresponsible processes). - One of basic tasks of general psychology is a study of personality, its structure and basic displays. - In 19-20 age formed great number of separate branches of psychological science, what associate with other sciences, including and medical psychology. Medical psychology is divided into general and special. General medical psychology studies: · · · · · · · · · Basic conformities to the law of psychology of sick man; Psychology of relatives and near patient; Psychology of medical workers in relation to each other; Psychological aspects of intercourse of physician with patients and their relatives; Psychological atmosphere in treatment - prophilaxy establishments; Internal picture of illnesses, psychosomatic and somatopsyche mutual relations; Influence of personality on motion of disease; Psychological aspects of medical deontology; Psychological aspects of psychotherapy, psychohygiene and psychoprophylaxy. The special medical psychology studies: · · · · · Features of psychology of patients with the boundary forms of nervous - psychiatric disorders which actually are the object of activity of doctor of any speciality; Psychology of patients on the stages of preparation, conducting of surgical interferences and in a afteroperative period; Features of psychology of persons with different diseases (cardio-vascular, infectious, oncologic, gynaecological, leather, nerve - psychic); Psychology of patients with the defects of organs and systems (blindness, deafness, deaf-and-dumb and etc.); Medic-psychological aspect of labour, military and judicial examinations. Industries of psychology: 1). Psychology of labour - studies the psychological features of labour activity of man, scientific organization of labour. l Tasks - research of professional features of man: l conformities to the law of development of skills of labours; l influence on the man of production situation, placing of machine-tools. l Psychology of labour has a row of sections: l engineering psychology is a problem of order and concordance of functions between people and machine; l aviation psychology, space psychology. l 2). Pedagogical psychology: study of psychological conformities to the law of studies and education of man. Its sections: l l it is psychology of studies (bases of didactics, programmable studies, forming of mental actions). psychology of education (psychology of education of student's collective). 3). Medical psychology, psychological aspects of activity of physicians, patient: neuropsychology: correlation of the psychological phenomena with physiology of cerebral structures; · psychopharmacy; · psychotherapy: facilities of the psychical influencing for treatment of a sick; · psychoprophylaxy and psychohygiene measures for providing of psychical health of people. · 4). Legal psychology is realization of right judicial: psychological features of conduct of participants of criminal process; · psychology of testimonies, conduct of accused, requirements to the interrogation; · criminal: conduct and formings of personality of criminal, reasons of crime; · community-service psychology. · 5). Military psychology. · 6). Sport psychology. · 7). Trade psychology (including influencing of advertising). · 8). Psychology of scientific creation. · 9). Psychology of artistic creation (in literature, art) and aesthetically beautiful perception. · 10). If to take the psychological aspects of development for basis, distinguish: age-old psychology: (child, psychology of teenager, adult, herontopsychology); · psychology of anomalous development; · olygophrenopsychology; · surdopsychology (defect of ear); · typhlopsychology (badseing and blind). · 11) Comparative psychology is research of filogenic form of psychical life, comparison of psyche of animals and man; animal psychology. 12). Social psychology: mutual relations of people from the different organized and unorganized groups of communities: l makro environments; l mіkro environments. Methods of psychology In psychology distinguish: l basic methods: supervision and experiment; l auxiliary: method of expert estimations, analysis of products of activity, methods of questioning (conversation, questionnaire, interview; l method of supervision; l method of tests etc. 1). Supervision: Advantages - conducted in a natural ordinary situation does not change behavior of persons; l it is possible to look after one person or group of persons; l very comfortable in the group of preschool or in a school class, student group; l supervision and fixing of single displays of psychical properties insufficient for reliable conclusions. 2). Experiment: laboratory and natural. Advantages: - it is possible specially to cause a certain psychical process it is possible to trace dependence of the psychical phenomenon on changeble external conditions. 3). Methods of questioning: Method of conversation: use on the different stages of research both for a primary orientation and for clarification of conclusions, got with the help of other methods (supervision). 4). Method of interview. Questionnaire. Difference: The method of interview foresees greater freedom of polled in forming of answer. 5). Method of expert estimations: widely use personality psychology. As experts can come forward competent persons which know explored well: educators of preschool, schoolsboarding-schools, leaders of classes, masters on a production, leaders of scientific collectives, sporting trainers and other 6). Method of introspection: widely used in empiric psychology of a 18-19 ages 7). Method of tests: tests, that the brief studies of properties of personality are more or less standardized Are you able to own the emotions? · Are you able to influence on other? · Are you understood in Cosmetology? · Are you able to get dressed? and etc 8). Concrete methods of psychological inspection: there are very much and depends on a purpose. For example, study of age-old changes of attention (to firmness), normal and morons children. Experimental method The experimental method is a research method used to demonstrate a cause-and-effect relationship between changes in one variable and the effect that is produced on another variable. Conducting an experiment involves deliberately varying one factor, which is called the independent variable. The researcher then measures the changes, if any, that are produced in a second factor, called the dependent variable. The dependent variable is so named because changes in it depend on variations in the independent variable. To the greatest degree possible, all other conditions in the experiment are held constant. Thus, when the data are analyzed, any changes that occur in the dependent variable can be attributed to the deliberate variations of the independent variable. In this way, an experiment can demonstrate a causeand-effect relationship between the independent and dependent variables. Sensation and perception l Sensation is a psychical process of reflection in our consciousness of separate properties of objects and phenomena of the objective world, which arise up at their direct influence on sense-organs. Sensation l l l l l l – the most elementary stage, which reflects separate quality of subject, which is acting in right moment on sensory organs. Classification : According to modality: Interoceptive – give signal about condition of our inner world: warm, cold, hunger, uncomfortability. These sensastions don’t have localisation, outside proection, closely connected with emotional processes. Exteroceptive – 5 sensation organs: smell, taste, sight, hearing, tactile. Proprioceptive – information about body position, movement in space, everything which makes body scheme. 1. Exteroreceptors (external). Distances: l a) an organ of sight - an eye; l b) an ear - is external and middle ears and frizz; l c) organ of smell - nose. 2. Contacts: l a) receptors of touch and pushing; l b) receptors of heat; l c) receptors of cold; l d) receptors of pain. 3. Interoreceprors (visceroreceptors). Receptors of the digestive system: l l l l l a) receptors of smell is - nosethroat; b) receptors of taste - are a tongue and throat; c) sensory cells of thirst - mucus of throat; d) sensory cells of hunger is - stomach; e) sensory cells of nausea is - stomach. Receptors Receptors Receptors Receptors of of of of the system of circulation of blood the respiratory system. the system of reproduction. pain of all internal organs. Feeling properties: · · · · · Absolute sensitiveness of sense-organs - to feel ability of man insignificant sizes of irritation. A feeling threshold - is a minimum or maximum size of irritant, which feeling is appear (to the 16-20 hrz. for ear). Adaptation - is a change of sensitiveness of analyzers as a result of adaptation of sense-organs to the operating irritant (light, warm). Sensibilisation - is an increase of sensitiveness as a result of co-operation (sound - light - disco). Habituation - is getting used, when certain irritants become so usual, that stop to influence on activity of higher parts of the brain (a townsman does not hear noise of cars, physicians - smell of medications Perception is a psychical process which consists in the integral reflection of objects and phenomena of outward things under direct influence of physical irritants on the receptors of sense-organs (auditory, visual etc). · · · · · · Integrity of perception - is an always integral reflection. Selectivity - appears in the grant of advantage one objects, to the phenomena or their properties before other (the trained nurse pays attention to the signs of illness). A constant of perception - is less-more relative firmness of separate properties of objects regardless of terms of perception (sun illumination and electric). The intelligentness of perception - is linked with understanding essence of object which is perceived. Apperception - is dependence on previous experience and its individual features and profession. Supervision - the intentional planned perception, conditioned by a concrete task, is integrally directed. Perceptions of colors and their influence are on the psyche of man Grey neutral - estrangement from surrounding l Green - calming - stability self-affirmation l Red - excitant - energeticness, unrestrainedness l Yellow - stimulant - life-breath l Dark blue calming - rest and passivity l Black - repressing - fencing off, promoted self-esteem, on occasion testifies to depression l Perception depends on: the state of receptors l leading ways l cork (brain) end of analyzers l consciousness l attention l emotions l vital experience l Violation of sensation: -hyperaesthesia - hypoaesthesia - anaesthesia Violation of sensation l l – Anesthesia – absence of 1 or more type of sensation. Analgesia – loss of pain sensation ( at acute psychopathological diseases.) Patients, who commit suicides: they cut their organs – at such moment they don’t feel anything. After some time everything comes back with recreation of psyche. ( At deep depression, progressive paralysis, brain syphillis, convulsive disorders(hysteria), anaestesia dolorosa depresia – absense of sensation). Hyperesthesia – subjective increasing of sensation. Hyperalgesia – increasing of pain sensastion (depression,espessially light). Violation of perception: l l Illusions: error perception or error interpretation of the real external irritants (physical, physiology, psychical). Hallucinations: error perception of non-existent sensory stimuli, here can take place (but not necessarily) delusional interpretation of the hallucinative experience. Hallucinations specify in the presence of psychosis only in that case, when they are connected with violation of real situation. l Illusions are perceptions that are associated with an outside stimulus, but the stimulus is wrongly interpreted. For example, lapping water may be heard as laughter. Technically, these are not hallucinations, as they are associated with a stimulus. Illusions are frequently visual, and they are usually the result of a medical condition. The condition which most commonly causes illusions is delirium tremens (DTs), the disturbed state which can complicate alcohol withdrawal. Objects such as creases in bed covers may be perceived as snakes, insects or other animals. Folk law says that people in DTs see pink elephants. In clinical practice, however, small organisms are more commonly “seen”. “Hallucinations” in healthy people l l Briefly, there are differences between the voices heard by healthy individuals and the hallucinations of those with mental disorders. In healthy individuals, the voice is usually as from one person, speaking comprehensibly, in a helpful and comforting manner. Auditory hallucinations in mental disorders, in contrast, often involve more than one voice, sometimes arguing, sometimes commenting about the patient, frequently making little sense, often in a threatening and frightening manner. PERCEPTION l - l Auditory or heard hallucinations are usually voices, however “nonverbal” auditory hallucinations occur, and include clicking and mechanical noises, muttering or mumbling and music. (In musical hallucinations the patient often hears a complete piece of music.) l l In the case of verbal auditory hallucinations, one or more voices may be heard simultaneously. They may come from inside or outside the head. Two or more voices may speak at the same time, or they may conduct a conversation between themselves. Imperative hallucinations l Voices may instruct or command the patient to perform an act. Usually this is a trivial act such as making a cup of tea, but it may be to injure him/herself or others. l Visual hallucinations may occur in a range of disorders, and may occur more frequently than auditory hallucinations in the organic mental disorders. In some types of epilepsy visual hallucinations may form complex scenes such as two trucks and a rickshaw driving through the room. l l l Tactile hallucinations are the experience of being touched or of a crawling sensation under the skin. These are common in drug withdrawal states, but may occur in schizophrenia. Somatic hallucinations are the sensation of things happening inside the body, such as organs moving from one part of the body to another. These are rare, but may occur in schizophrenia. Gustatory hallucinations, the hallucinations of taste and smell , are more common in medical conditions, particularly epilepsy, but may rarely occur in schizophrenia. PERCEPTION l S-m Lippman, s-m Ashaphenburg, s-m Reyhardt. PERCEPTION - PERCEPTION - Psychology of memory l Sometimes, when we think of our memory, we imagine it as a mental "filling cabinet" in which we deposit isolated facts that we want to be sure to retain - such as the dates of the revolutions, or out mother's birthday, or the errands we must be sure to do on the way home from work. But that is only a partial description of our memory. l Our memory encompasses everything we have recently perceived and everything we know or can recollect - about people, places, music, pictures, ways of doing things, languages, emotional feelings, dreams, actions, and skills. Memory (from GREEK. - mnema) is a capacity for fixing, storage, recreation and FORGETTING of various experience and information. Basic processes (functions) of memory: Memorizing of information (fixing); · Saving or maintenance of information (RETENSION); · Recreation of information (reproduction); · Forgetting of information. Psychologist analyze the memorizingremembering cycle into three distinct processes: acquisition, l retention, l and retrieval. l l Acquisition is the process by which we initially perceive, register, and record information in our memory. If you do not pay attention and register something in the first place, you will never be able to remembcr it. l Retrieval is the process by which we get information out of storage and bring it back into our awareness. You may register a piece of information and store it, but then find yourself unable to bring it back to mind — until someone gives you a good cue that "jogs your memory". l Human memory retains 2 types of information: Specific - accumulated in the process of evolution during many millenniums, appears unconditioned reflexes and instincts, passed inherited; l Gained in the process of living by everybody and realized in Pavlovs reflexes. Memorizing After the degree of activity of man: Involuntary (passive); · Arbitrary (active). Depending on connections which memorizing is made: Mechanical (“learning by heart”); · Semantic (logical). On content - 4 types of memory: · Motive; · Emotional; · Vivid; Associative (word-logical). l Personal memories consist of distinct episodes we have witnessed, such as this morning's breakfast, when we remember such episodes, we can "see" the event taking place, and our mental images carry a sense of the past. l Generic memories, by contrast, include memories that are abstract and are not tied to any particular time or place; we do not usually remember where we leaned them. They include memories that are primarily semantic or meaning related, rather than being scenes. Concepts such as "love" or "constitutional monarchy" are generic memories. Generic memories also include perceptual memories of the way things look, sound so on. Associative models suggest that semantic memory consist of relationships between pieces of information, such as those relating to the concept of “animal”, shown in this figure l Skill memories consist of cognitive skills, such as our ability to solve quadratic equations; motor .,such as our knowledge of how to ice skate or put in a light bulb, verbal sequences we have memorized, such as our phone number. Memory is divided into three kinds or stages: l l l sensory memory, short-term memory, and long-term memory Sensory memory l Is the shortest stage. It involved the brief holding of information after stimulus has been removed. If we pay attention to that which was in sensory memory the information enters short-term memory l Virtually every moment of your waking life you have memories that are simply the aftereffects of your sensory processes. These fleeting sense impressions, known as sensory memories, last for just a tiny interval of time. Our visual world maintains its stability even though we blink frequently as we look about us. This phenomenon is related to our sensory memory. Similar sensory aftereffects exist for touch and hearing. We rely on auditory aftereffects in conversation: the persisting auditory images enable us to process speech sounds after the speaker has gone ahead with his or her remarks. l Short-term memory. Many of our sensory memories simply fade almost immediately. But if we pay close attention to a sensory memory, that record enters a more durable phase, we call it short-term memory. Short-term memory is a temporary form of memory that lasts many seconds; it is also known as active memory or primary memory. Here is how short-term memory operates. While we are attending to a sensory event, we may also retrieve associations to that event from more durable parts of our memory. These retrieved associations themselves become active as part of our memory of the event. In essence, we have converted the information from one form to Long-term memory (LTM) l In witch information is stored for much longed period. An important different between short-term memory and long-term memory pertains to their capacity. That of LTM is enormous, while that of only about seven items, as shown by studies of memory span l Long-term memory. Now try to remember your mother's maiden name. Do you have it as an active trace? Before you remembered it, the name was inactive; it was in what is called long-term memory, out of your consciousness. Then, when you retrieved it, the name was aroused into your consciousness, into short-term memory. This description is metaphorical. You did not actually move the name from one place to another in your mind, because memory is not a set of places. Instead, a given item can be either active or inactive: it can be in your consciousness, or it can be out of your l Long-term memory is what most people think of when they talk about memory: the total content of our long-term memory encompasses that tremendous range of knowledge, ideas, images, skills, and feelings that we have gathered in the course of our experience. All these items of knowledge are inactive for the moment, but they can be retrieved, given an appropriate request, and "brought into" short-term memory. So short-term and long-term memories have a close, Quality and durability of memorizing is stipulated: By the type of memorizing. · By interest to that which is memorized. · By volitional effort. · Setting on time. · By an orientation on durability. · By application of the special receptions of mnemotechnic. What mnemonic strategies are l Mnemonic strategies are systematic procedures for enhancing memory. Their particular use is in developing better ways to take in (encode) information so that it will be much easier to remember (retrieve). Although there are retrieval strategies that can be employed to attempt to retrieve information that has been forgotten, research has demonstrated that the way we encode information when we first study facilitates memory better. The particular task in developing mnemonic strategies is to find a way to relate new information to information students already have locked in long-term memory. If we can make a firm enough connection, the For information involving key words Acronym - an invented combination of letters with each letter acting as a cue to an idea you need to remember. l BRASS is an acronym for how to shoot a rifle-- Breath, Relax, Aim, Sight, Squeeze. l For ordered or unordered lists Rhyme-Keys - a 2-step memory process: Memorize key words that can be associated with numbers (one-bun); l Create an image of the items you need to remember with key words. (A bun with cheese on it will remind me of dairy products.) l Food groups: l Dairy products: one-bun-cheese on a bun. l Meat, fish, and poultry: two-shoe-livestock with shoes. l Grains: three-tree-sack of grain hanging from tree. l Fruit and vegetables: four-door- opening a door and walking into a room stocked with fruits and vegetables. l For foreign language vocabulary Keyword Method- Select the foreign words you need to remember, then identify an English word that sounds like the foreign one. Now imagine an image that involves the key word with the English meaning of the foreign word. l In Spanish, the word "cabina" means phone booth. Invent an image of a cab trying to fit in a phone booth. When you see the word "cabina," you should be able to recall this image and thereby retrieve the meaning "phone booth." l For approximately twenty items l l Loci Method- Imagine placing the items you want to remember in specific locations in a room with which you are familiar. To remember presidents:Place a dollar bill (George Washington) on the door. Walk into the room and see Jefferson reclining on a sofa and Nixon eating out of the refrigerator. For remembering names l l Image-Name Technique- invent a relationship between the name and the physical characteristics of the person. Shirley Temple - her curly (rhymes with "Shirley") hair around her temples. For ordered or unordered lists Chaining- Create a story where each word or idea you have to remember will cue the next idea you need to recall. l Napoleon, ear, door, Germany Story: Napoleon had his ear to the door to listen to the Germans in his beer cellar. l With saving of information forgetting is closely associated. l l l l l l l Ebbinhaus (german scientist) led to: through 0,5 hour. after learning remains 60 % perceived information; · in 1 day - 34 % (1/3) · in 3 days - 25 % (1/4) · in 30 days - 21 % (1/5) · in 1 year - 15 % ( 1/6) Conclusion: It follows in good time to repeat the perceived information. Recreation (reproduction): Mention (without the repeated perception): landscape, a book etc. Recognition (a condition - is the repeated perception of some object): kid and mom etc· Facilitating memory (information actively is not remembered, but at the repeated study memorized easier). A recreation is: involuntary (unintentionally); · arbitrary (intentionally). Productivity of memory: Speed is an amount of reiterations, necessary for memorizing of certain information; · Exactness is an amount of errors, done at the recreation of information; · Durability is duration of saving of learned material or speed of him forgetting; · Readiness - as far as a man can quickly and easily to remember in a necessary moment that he needs. Practical recommendations. Phenomenon of Ebbinhaus: if to study material parts, a total expense of time will be less, than study of all block. · Phenomenon of Muller: it follows to divide material no more than on 7 parts. · Remember: a sick man memorizes less information, that is why better to write down necessary information to him. · Factor of edge: The first is better memorized, and the best is the latest report. · Factor of sleep: It is the best to learn major material or repeat before sleep.It is necessary to have a good sleep before examination or test. · Factor of writing down of information. Law of Ebbinhaus: quick in all information drops off at first o'clock (to the days). Through 0,5h. after learning in memory remains 60% the perceived information, in 1 day - 34%, in 3 days 25%, and in 30 days - only 21%. Factor of motivation (to the personal interest). Principle is “violence and to naturalness”. A child masters a language without efforts above itself, and to the schoolboy heavier. Phenomenon of Freud: negative information is psychogenically memorized by histeric persons worse and drops off quick. Phenomenon of “absolute novelty”: It follows tactfully to a patient to tell new and basic to write down as a message. l Thank you for your attention!
