MEMORY • • • • Key memory concepts Multi-Store Models and Evaluation Reconstructive Model of Memory and Evaluation Application of Memory Recap – The cognitive area The study of mental processes Information processing Attention Memory What is memory? 1.What is memory? 2.Why do we need our memory? What would life be like without it? 3.How do you think memory works? Three key stages of memory ENCODING Changing incoming information in a way that it can be stored STORAGE Keeping information in the memory system RETRIEVAL Recovering information in the memory system ENCODING Changing incoming information in a way that it can be stored Incoming information comes from any of the five senses Information is changed into a ‘code’ that can be understood by the brain STORAGE Keeping information in the memory system RETRIEVAL Recovering information in the memory system 1. Multi-Store Model of Memory Sensory information is encoded and stored in either the short or long-term store Information enters the sensory store from our senses Eyes Nose Information passes to the short-term store Short-Term Store Long-Term Store Ears Mouth Skin Information that is rehearsed is transferred to the long-term store 1. Multi-Store Model of Memory The three stores in the multi-store model differ in their capacity and duration Sensory Store Attention Short-Term Store Rehearsal Long-Term Store 1. Multi-Store Model of Memory The three stores in the multi-store model differ in their capacity and duration CAPACITY How much information can the store hold? DURATION How long will the store hold information for? 1. Multi-Store Model of Memory The three stores in the multi-store model differ in their capacity and duration Capacity • Very large to accommodate all sensory experiences SENSORY STORE Duration • ¼ to ½ a second Encoding • Sense specific – separate areas for each sense 1. Multi-Store Model of Memory The three stores in the multi-store model differ in their capacity and duration Capacity • 7±2 items. i.e 5-9 chunks of info SHORT-TERM STORE Duration • 0-18 seconds Encoding • Mainly auditory encoding (sound) 1. Multi-Store Model of Memory The three stores in the multi-store model differ in their capacity and duration Capacity • Unlimited LONG-TERM STORE Duration • Unlimited, but depends on use of information Encoding • Mainly semantic, but may also be auditory or visual (Semantic information = Information that has some sort of meaning.) Your Task Use your Memory workbook to work through pages 2 - 6 1. Multi-Store Model of Memory - Evaluation To evaluate … • To judge how good something is based on it’s characteristics • To look at something critically to assess it’s weak points Memory Test • Listen to the words • Wait for 30 seconds • Then write down as many of the words as you can remember 1. Multi-Store Model of Memory - Evaluation Murdock’s recency and primacy effect Supports the model Words at the beginning of the list have been rehearsed and transferred to the long-term store Words at the end of the list have just been heard and are still in the shortterm store Number of words remembered Beginning of list End of list 1. Multi-Store Model of Memory This model says that rehearsal, or repetition, of information is essential for the transfer of information from the shortterm store to the long-term store. The BIG Question What else could influence whether information is transferred to the long-term store? What else could influence whether information is transferred to the long-term store? Where were you when you heard about these events? 1. Multi-Store Model of Memory - Evaluation What else could influence whether information is transferred to the long-term store? • Information that is significant in our life, often with an emotional meaning attached to it, is naturally more likely to be remembered Refutes the model 1. Multi-Store Model of Memory - Evaluation The model is reductionist It’s too simple! Reductionist = A focus on only one aspect, ignoring other factors that may influence something 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Background Amnesia (memory loss) has two forms: Retrograde Amnesia Anterograde Amnesia A loss of memory from before the onset of illness or injury Inability to form new memories after the onset of illness or injury Flawed memories may take two forms: • Distortion of events that have occurred • Distorted beliefs about things Clive Wearing 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Aim This research documents the case of Clive Wearing, a man suffering from both retrograde and anterograde amnesia Sample Clive Wearing Watch the documentary about the man that this study is focused on Active Listening Task – Make notes throughout the documentary 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Research Method Longitudinal Study A study that is conducted over a long period of time to gather in-depth information about a person’s behaviour as they change and get older. Case Study A study that focuses on one person or a very small group of people. 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Method Clive Wearing developed an illness causing large sections of the brain to be destroyed. He developed problems with memory and was referred for investigations. 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Method First tests • Clive’s IQ scores had decreased from the levels they were at before the illness • Clive’s short-term memory was normal • Clive’s long-term memory was severely impaired Short-Term Store Long-Term Store 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Method Brain Scans There were differences in brain areas when compared with a ‘normal’ brain. The areas affected included the hippocampus, an area involved in memory Clive 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Method Further tests Clive always scored zero on tests of long-term memory and showed an inability to form new memories Poor long-term memory = Retrograde Amnesia Inability to form new memories = Anterograde Amnesia • Clive could still talk, read, write and conduct music • He could not recall many facts from before illness, but knew who he was, that he was a musician, and that he was married. 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Method Consciousness Because Clive could not remember things from more than 30 seconds ago, he constantly believed that he had just woken up from a coma. 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Results Overall, Clive was found to suffer from: • • • • • Brain abnormalities Retrograde Amnesia Anterograde Amnesia Inability to transfer information from STM to LTM Lowered IQ 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Conclusions • There is a clear interaction between the brain and memory (cognition) • Brain damage can cause a loss of memory, indicated by both retrograde and anterograde amnesia 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). Evaluation When evaluation research in psychology, there are a number of factors we can focus on: GRAVE Generalisable Reliable Applicable/Useful Valid Ethics 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). GRAVE Evaluation Generalisable Can the findings of the research be applied to the wider population? Case studies lack generalisability because the findings are limited to a unique individual, and may not apply to everyone. 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). GRAVE Evaluation Reliable Is the research finding something consistent? Are the procedures used consistent for all tests? The case study looks at only one individual, so we cannot assume that a consistent effect would be found among all people suffering in the same way as Clive Wearing 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). GRAVE Evaluation Applicable Are the findings applicable and useful in everyday life? Gives us an insight into problems individuals may have after suffering illnesses and disease that affects the brain 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). GRAVE Evaluation Valid Is the research measuring what it intended to measure? E.g. are the findings really showing measures of memory, or have they measured something else? Accurate view of memory loss in an individual with amnesia. Tests of memory were accurate tests. 1. CORE STUDY Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy (the Clive Wearing study). GRAVE Evaluation Ethics What ethical guidelines has the research either kept/broken? All ethical guidelines were adhered to. There may be a slight issue with privacy, but Clive has likely chosen to make his story public.

Reconstructive Theory of Memory You have 30 seconds to write down as many of the words as you can Did you get the word sweet? 1. Reconstructive Theory of Memory We like to think that our memory is good, but sometimes our memory can become flawed If we find gaps in our memories, we fill these gaps in with our prior knowledge and common sense SCHEMAS 1. Reconstructive Theory of Memory SCHEMAS Our prior knowledge and common sense is organised into schemas, a little like a filing cabinet containing sections for everything about everything we know about! 1. Reconstructive Theory of Memory Our prior knowledge and common sense is organised into schemas, a little like a filing cabinet containing sections for everything about everything we know about! Some people dislike police because they have a schema of police as people who perceive everyone as guilty until proven innocent. Other people feel safe around police as their schemas are more about police as brave protectors. 1. Reconstructive Theory of Memory Key Term CONFABULATION A false memory produced by an individual with no conscious awareness that the memory is false 1. Reconstructive Theory of Memory Leading Questions Some situations are more likely to produce false memories than others. A leading question is a question that hints to the desired answer. 1. Reconstructive Theory of Memory Leading Questions "How much will prices go up next year?” 1. Reconstructive Theory of Memory Leading Questions “Did he hit you in the face with his fist?” 1. Reconstructive Theory of Memory Leading Questions "You ignored the warning labels, didn't you?" 1. Reconstructive Theory of Memory When do leading questions become a problem? During court cases, leading questions can cause false evidence to be given. This could lead to prosecution of the wrong person, or even the guilty person getting away with a crime 1. Reconstructive Theory of Memory Evaluating the theory Supports the model Research by Bartlett – War of the Ghosts Bartlett (1932) asked people to reproduce an unfamiliar story they had read based on a Native American legend. Bartlett found that people changed the story to fit into their existing knowledge. For British participants, the story was filled with unknown concepts and was unfamiliar for those brought up in a British culture. When asked to re-tell the story, British participants changed information to make it more consistent with British culture, and often added in extra information and left out information they thought wasn’t necessary. 1. Reconstructive Theory of Memory Evaluating the theory Refutes the model Does the theory go into detail about how information is encoded, stored and retrieved? Does the theory talk about ways in which memory is influenced by what information is being learned? E.g. is it meaningful? 1. Reconstructive Theory of Memory Evaluating the theory The model is reductionist Refutes the model The role of reconstruction is too simplistic to explain memory as a whole • What about encoding? • What about storage? • What about retrieval? • How does reconstruction happen? 2. CORE STUDY Background Braun, Ellis and Loftus (2002) How advertising can change our memories of the past • Advertising campaigns may use images to cue peoples autobiographical memory. • Cues that cause people to think over and over about childhood events may be a good way to cause peoples’ memory to change. This is particularly likely if the events have had time to fade and decay. • Sometimes the content of the adverts may lead consumers to imagine themselves in the advertised event. This may alter how they remember their own past. Autobiographical Memory Memory of past and personal experiences 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past There were 2 experiments within this core study To do today …. Task 1 Using the resources you have been given, complete a story board to show the steps of the core study by Braun, Ellis and Loftus. Do this ONLY for experiment 1 Task 2 Create a table to show the aim, sample, IV, DV etc of experiment TWO of the Braun, Ellis and Loftus study. There are some ready made tables at the front if you want one • Homework is on the board. IF you finish all of the above then you may start revising now. • There is coloured paper at the front if you want to use it for flashcards, posters etc … 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 To investigate whether autobiographical advertising can prompt consumers to imagine their childhood experiences so their memories become more consistent with the images evoked in the advertisement. In simpler terms … Can autobiographically focused advertising directly affect how consumers remember prior childhood experiences. Autobiographical Memory Memory of past and personal experiences 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Research Method What do these terms mean? Laboratory Experiment Independent Measures Design Questionnaires to gather information Autobiographical Memory Memory of past and personal experiences 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Sample Opportunity Sampling 64 43 107 university graduates 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Method Participants randomly allocated to one of two conditions… 46 in the Disney advert condition 51 in the Non-Disney advert condition 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experimental Design Independent Measures Participants are split into two groups Each group does something different So … participants do only one of the tasks Independent Variable Whether they watched the Disney or the Non-Disney advert Dependent Variable The key thing they wanted to measure was … Whether or not the person increased their score on how likely it was that they had shaken hands with Mickey Mouse 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Method Participants completed a questionnaire with 20 childhood events. They had to rate on a scale of 0-100 on the likelihood that an event happened during their childhood. 0 Definitely did not happen 100 Definitely did happen There was ONE critical event in the list of 20. The ONE critical event was the one the researchers were interested in. ‘Met and shook hands with a favourite TV character at a theme resort’ 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Method Participants saw either a Disney advert or a Non-Disney advert Then asked … 1. How did the advert make you feel and what did it make you think about? 2. Rate the advert as ‘favourable-unfavourable’, ‘good-bad’, ‘unpleasant-pleasant’ 3. Rate statements indicating how involving the advert was for them 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Method There was a problem with coding the results of the questionnaire you completed in week 1, please complete it again. Participants then carried out a small distractor task Participants were then given another questionnaire asking about their memories of Disney 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Findings • 30 (65%) of the participants in the mentioned memories of Disney World. condition • 34 (74%) of those participants were able to imagine the experience, even if they had never visited the park. Autobiographical Memory Memory of past and personal experiences 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Findings 90% increased their scores from Week 1 – 2 on the critical question about whether they had shaken hands with Mickey Mouse at a Disney resort Only 47% increased their scores from week 1 – 2 on the critical question about whether they had shaken hands with Mickey Mouse at a Disney resort 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Findings No differences in negative thoughts between the two groups • 34 people reported visiting a Disney resort in the past • More positive thoughts about Disney • More ad elements were used in the recall descriptions. • 34 people reported visiting a Disney resort in the past • Fewer ad elements were used in the recall descriptions. EXPERIMENT TWO 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Method Participants completed a questionnaire with 20 childhood events. They had to rate on a scale of 0-100 on the likelihood that an event happened during their childhood. 0 Definitely did not happen 100 Definitely did happen There was ONE critical event in the list of 20. The ONE critical event was the one the researchers were interested in. ‘Met and shook hands with a favourite TV character at a theme resort’ 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 1 – Method Participants saw one of the following adverts NonAutobiographical advert 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 2 This was a variation of experiment 1. There were 3 conditions, but the ad they watched was different. NonAutobiographical advert Independent Variable The thing that was changed …. Whether they watched the video about Bugs Bunny, Ariel or a nonautobiographical advert 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 2 This was a variation of experiment 1. Group 1 were asked if they remembered shaking hands with Bugs Bunny at a Disney resort when they were less than 10 years old. This would have been impossible as Bugs Bunny is NOT a Disney character 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 2 This was a variation of experiment 1. There were 3 groups, but the ad they watched was different. Group 2 were asked if they remembered shaking hands with Ariel at a Disney resort when they were less than 10 years old. This would have been impossible as Ariel had not been created when the participants were younger than 10 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Experiment 2 This was a variation of experiment 1. These ads were rated as more involving than the non-autobiographical ad. All groups increased their score of likelihood of having shaken hands with one of the characters, but more so in the autobiographical conditions. 76% increased their score of how likely it was that they had shaken hands with Ariel 78% increased their score of how likely it was that they had shaken hands with Bugs Bunny Remember – We know that in both cases, it would have been impossible to have shaken hands with either character at DisneyLand! Dependent Variable Whether or not the person increased their score of how likely it was that they had shaken hands with the character 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Overall Conclusions • Autobiographical advertising can make consumers more confident that they’ve experienced an advertisedsuggested event as a child • Autobiographical advertising can influence how consumers remember the past • Featuring impossible events in autobiographical advertising can cause people to believe they have experienced the events • Autobiographical referencing/advertising can lead to the creation of false or distorted memory. 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past Evaluation When evaluation research in psychology, there are a number of factors we can focus on: GRAVE Generalisable Reliable Applicable/Useful Valid Ethics 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past GRAVE Evaluation Generalisable Can the findings of the research be applied to the wider population? A large sample of participants was included. However, all participants were university students, so it may not apply to other people in the wider population. 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past GRAVE Evaluation Reliablity Are the findings consistent? Is the procedure standardised and controlled? Standardised/Controlled Procedure The procedure is exactly the same for all participants. A considerable effort is made to reduce the effects of extraneous variables that could influence the results (e.g the weather, time of day) 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past GRAVE Evaluation Reliablity Are the findings consistent? Is the procedure standardised and controlled? Laboratory experiments aim to control lots of factors to ensure it is only the independent variable affecting the results. This makes it highly reliable! 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past GRAVE Evaluation Applicable Are the findings useful and applicable to the wider society? The findings are highly useful to advertisers who want to use autobiographical advertising to influence their consumers. 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past GRAVE Evaluation Validity Are the findings accurate representations of the real-world? This is known as ecological validity. Research that takes place in laboratories is often artificial. The tasks the participants are asked to carry out are not tasks you would often be asked to do in the real-world. It LACKS ecological validity. 2. CORE STUDY Braun, Ellis and Loftus (2002) How advertising can change our memories of the past GRAVE Evaluation Ethics Has the research broken any guidelines? Which guidelines has it kept to? We can assume that all ethical guidelines were kept in this research. Unless stated otherwise, we can always assume that informed consent was obtained and that debriefing took place.

Reconstructive Theory of Memory Key Term CONFABULATION A false memory produced by an individual with no conscious awareness that the memory is false Advertising Sometimes, the adverts we see either on TV or in a newspaper can cause us to develop false memories The information we see in the advert can infiltrate our own memories, making us believe it really happened to us Autobiographical Adverts Autobiographical memory = Memories of our past personal experiences Autobiographical adverts =Tapping into autobiographical memory via adverts Autobiographical adverts can cause nostalgia A feeling of wanting to return to a past time or event, or wishing for life to be like it was • This causes us to put aside rational thought, such as ‘do we really need this item?’, ‘Is this really worth the money?’. • Nostalgia causes us to not think straight! Autobiographical Adverts and false memories Sometimes, these adverts can cause a false memory to be made. The advert might trigger one of our schemas, and we then integrate the new information from the advert, making us believe it is part of our real memory.

What do you think happens when we forget something? In pairs .... 15 minutes ... Use the three images to try to come up with three explanations for why we forget Forgetting Three theories of forgetting: • Decay • Displacement • Retrieval Failure Forgetting - Decay The fading of information over time Today you can remember what we have done in class It’s unlikely you will remember this in 3 years time This assumes that information has a physical trace in the brain. If we don’t use the information, It gets weaker and fades (decays) Forgetting - Displacement New information pushes old information out New information enter the STM SHORT-TERM MEMORY STORE Old information is pushed out of the STM The short-term store can only hold up to 9 pieces of information. When we learn new information, it pushes the old information out of the store and it is lost. Forgetting – Retrieval Failure Not being able to access the information We rely on cues to aid our memory. We can remember things better if we are in conditions that closely resemble the conditions we were in at time of encoding.
