AQA AS Psychology New Spec: Memory
  1. Forgetting
    1. Interference
      1. Proactive
        1. Past learning interferes with current attempts to learn
          1. E.g. You previously learned Spanish so now struggle to learn French
            1. Key Study: Underwood (1957)
              1. When participants had to learn a series of word lists they didn't remember the lists encountered later on.
                1. When one list was memorised, participants remembered 70% of the information. When 10 or more were memorised, participants remembered 20%.
              2. Retroactive
                1. Current learning interferes with past learning
                  1. E.g. You forget your old phone number after learning your knew one
                    1. Key Study: Postman (1960)

                      Annotations:

                      • Key study: Postman (1960) Aim: To investigate how retroactive interference affects learning.  In other words, to investigate whether information you have recently received interferes with the ability to recall something you learned earlier. Method: A lab experiment was used. Participants were split into two groups.  Both groups had to remember a list of paired words – e.g. cat - tree, jelly - moss, book - tractor.  The experimental group also had to learn another list of words where the second paired word is different – e.g. cat – glass, jelly- time, book – revolver.  The control group were not given the second list. All participants were asked to recall the words on the first list. Results: The recall of the control group was more accurate than that of the experimental group. Conclusion: This suggests that learning items in the second list interfered with participants’ ability to recall the list.  This is an example of retroactive interference. Evaluation Although proactive and retroactive interference are reliable and robust effects, there are a number of problems with interference theory as an explanation of forgetting.  First, interference theory tells us little about the cognitive processes involved in forgetting.  Secondly, the majority of research into the role of interference in forgetting has been carried out in a laboratory using lists of words, a situation which is likely to occur fairly infrequently in everyday life (i.e. low ecological validity).  As a result, it may not be possible to generalize from the findings. Baddeley (1990) states that the tasks given to subjects are too close to each other and, in real life; these kinds of events are more spaced out.  Nevertheless, recent research has attempted to address this by investigating 'real-life' events and has provided support for interference theory. However, there is no doubt that interference plays a role in forgetting, but how much forgetting can be attributed to interference remains unclear (Anderson, 2000).

                      1. Recall was higher when only given one list to learn
                      2. Jenkins and Dallenbach (1924)
                        1. People who learnt information and then went to sleep would remember more than those who learnt information and then carried out their normal daily activities
                          1. Concluded the events of the day had interfered with the information
                        2. AO3
                          1. Tells us little about cognitive processes
                            1. Most research into interference was lab-based and low in ecological validity so can't be generalised
                              1. Some research supports
                            2. Retrieval Failure
                              1. Cue/Context/State Dependent Forgetting
                                1. Cue: Something that happens/is said/seen
                                  1. Context: Environment
                                    1. State: Emotional and mental state, e.g. happy, sad, drunk
                                      1. Context Study: Godden and Baddeley
                                        1. Some remembered words on shore, some remembered underwater.
                                          1. Remembered more when in same environment.
                                        2. Cue Study: Aggleton and Waskett
                                          1. A group of participants recalled more at Jorvik when the same smells were present.
                                          2. State Study: Carter and Cassaday
                                            1. Gave anti-histamines and a recall task. Recalled more when in same state as encoding.
                                          3. Memories are present in LTM but inaccessible due to lack of correct trigger
                                            1. Tulving and Pearlstone (1966)
                                              1. Gave participants a list of 48 words in 12 categories of 4 words each. Each category had a heading. Some participants were given the headings as cues and others weren't, and they were asked to recall the words.
                                                1. Participants with cues remembered more
                                              2. AO3
                                                1. Most studies were lab based so highly controlled and replicable
                                                  1. Low ecological validity
                                                  2. Huge amount of support so seen as main explanation
                                                2. Eyewitness Testimony
                                                  1. Leading Questions
                                                    1. Loftus and Palmer
                                                      1. Showed university students a video of a car crash. Asked to estimate speed, using differently phrased questions.
                                                        1. When more violent verbs were used, higher speeds were estimated, and vice versa.
                                                          1. After this they asked about seeing broken glass. Again, when more violent verbs were used, more believed they had seen broken glass
                                                        2. AO3
                                                          1. Would be different in real life, other factors would affect it, more emotion and stress (low ecological validity)
                                                            1. Sensitive issue, psychological damage
                                                        3. Witness Discussion
                                                          1. When witnesses discuss the crime, they may change their opinions/what they remember unintentionally based on what they hear
                                                          2. Anxiety/Yerkes Dodson
                                                            1. The Yerkes Dodson Law states there is a bell curve for level of arousal and anxiety with an optimum level. If one surpasses this level, performance will decrease (i.e. less will be remembered)
                                                            2. Weapon Focus
                                                              1. If there's a weapon on the scene one may focus on this and be distracted from other details
                                                              2. Repression
                                                                1. An experience may have been so stressful that they have forced the memory down, i.e. repressed it (suggested by Freud)
                                                                2. The Cognitive interview
                                                                  1. 4 Key Features
                                                                    1. Report Everything
                                                                      1. Get irrelevant information
                                                                      2. Report in a different order
                                                                        1. Recreate the context
                                                                          1. Potential stress + psychological damage
                                                                          2. Report from someone else's PoV
                                                                          3. Economic Implications: Less wrongly convicted, more accurate police reports, less criminals on the streets. However, time and money is required to train officers to do the cognitive interview.
                                                                            1. Fisher and Geiselman
                                                                              1. Showed a violent video of crime and interviewed with standard and cognitive 48 hours later. Recall of accurate statements was significantly higher with cognitive interview
                                                                                1. AO3
                                                                                  1. Psychological trauma, violent videos may cause harm, may need therapy
                                                                                    1. Low ecological validity, just a video, no anxiety/weapon focus/yerkes dodson effects.
                                                                                  2. Enhanced Cognitive Interview
                                                                                    1. Can be used on children
                                                                                      1. Less distraction ensured
                                                                                        1. Witness given control over flow of information
                                                                                          1. Open ended questions
                                                                                            1. Speak slowly, allowed to say I don't know
                                                                                      2. Remembering
                                                                                        1. Models
                                                                                          1. The Multi-Store Model
                                                                                            1. AO1
