Rorschach test: a projective test that uses inkblots as the ambiguous stimulus 15 338. safety: the second rung of Maslow's hierarchy; refers to need for freedom from danger 339. scapegoat: this theory says that having suffered negative experience, an individual might blame an innocent person or group for the experience and subsequently mistreat the person or group 340. scatterplot: name for a graph of data points in a two variable correlation 341. schedules of reinforcement: these include fixed interval and variable ratio 342. schema: a collection of basic knowledge about a category of information; serves as a means of organization and interpretation of that information 343. schemata: plural form of schema 344. schizophrenia: disorder characterized by hallucinations and delusions 345. selective attention: this term describes the situation when you are focused on certain stimuli in the environment while other stimuli are excluded 346. self-actualization: the highest of Malow's needs; "the full use of talent" 347. self-concept: one's idea and evaluation of oneself; this contributes to one's sense of identity 348. self-efficacy: one's ability to act effectively to bring about desired results; from Bandura 349. self-esteem: the more positive one's estimation of one's qualities and characteristics, the higher this is 350. self-fulfilling prophecy: a belief or expectation that helps to make itself true 351. self-serving bias: he tendency to assign oneself credit for successes but to blame failures on external forces 352. semantics: in language, study of meanings of words 353. sensorimotor: describes Piaget's stage in which the child explores the world through interaction of his mouth and hands with the environment 354. sensory adaptation: reduced responsiveness caused by prolonged stimulation 355. sensory cortex: the parts of the brain that receive information from the sensory receptors 356. sensory neurons: nervous system cells that receive information from the environment 357. serial position effect: this tells us that the best recall of a list of items will be of those at the beginning of the list 358. serotonin: a neurotransmitter; associated with improved mood and other positive emotions 359. set point: the point at which one's body tries maintain weight 360. sexual response: its four stages are excitement, plateau, orgasm and resolution 361. shaping: an operant conditioning technique in which reinforces guide behavior to closer and closer approximations of the desired behavior 16 362. short-term: type of memory that holds a few items briefly before they are lost 363. signal detection: this theory predicts how and in what circumstances we can detect a stimulus; assumes there is no single threshold 364. sleep apnea: a disorder characterized by cessation of breathing during sleep 365. sleep spindles: short bursts of brain waves detected in stage 2 sleep 366. social exchange: a theory that suggests that our behavior is based on maximizing benefits and minimizing costs 367. social facilitation: a phenomenon in which we perform simple or well-learned tasks better when in the presence of others 368. social learning: a theory that suggests we learn social behaviors by watching and imitating others 369. social norm: a group's determination of socially acceptable behavior 370. socio-cultural: a perspective on psychology that emphasizes effects on behavior and thinking of one's culture and the people around one 371. somatic: a division of the nervous system that controls voluntary muscle movements 372. somatoform disorder: any of a group of psychological disturbances characterized by physical symptoms for which there is not a medical cause 373. split brain: a condition in which the two brain hemispheres are isolated by cutting the corpus callosum 374. spontaneous recovery: in classical conditioning the re-occurence of conditioning after it had appeared to be extinct 375. SSRI: class of drugs used to relieve anxiety by limiting reuptake of a neurotransmitter 376. standard deviation: a computation of how much scores vary around a mean 377. stereotype: a set of generalizations about a group 378. structuralism: school of psychology developed by Wilhelm Wundt 379. sublimation: a defense mechanism in which unacceptable energies are directed into socially admirable outlets, such as art 380. superego: the part of the personality in Freud's theory that is responsible for making moral choices 381. sympathetic: part of the nervous system that controls the "flight or fight" response 382. synaptic gap: space between the axon terminal of one neuron and the receptors of the next neuron 383. syntax: in language the set of rules that describe how words are arranged to make sentences 384. TAT: a projective test in which subjects look at and tell a story about ambiguous pictures 17 385. temperament: personality component that ranges from very calm to very exitable 386. temporal: the lobe that controls audition 387. thalamus: the sensory switchboard 388. theory: this organizes data and is used to make predictions 389. threshold: in a neuron, reaching this causes the neuron to fire 390. token economy: a technique in operant conditioning by which desired behaviors receive forms of currency that can be exchanged for rewards 391. twin studies: a common method of investigating whether nature or nurture affects behavior 392. unconditioned response: in conditioning the behavior elicited by the unconditioned stimulus 393. unconditioned stimulus: in conditioning it elicits the UCR 18
