Q

TYPES OF LTM (Tulving).

A
  • EPISODIC= Memories of events, places + people. (Time stamped+ conscious effort to recall).
  • PROCEDURAL= Motor skill memories. (No conscious effort).
  • SEMANTIC= Memories of facts + knowledge.

Q

EXPLAINATIONS FOR FORGETTING.

A
  1. Interference theory.
  2. Retrieval failure.
17
Q

INTERFERENCE THOERY.

A
  • Forgetting because one memory blocks another, causing distortion/ forgotten memories.
  • Likely to occur when 2 memories stored at different times.
  • 2 TYPES=
    PROACTIVE. (old memory interferes with new).
    RETROACTIVE. (new memory interferes with old).
18
Q

MCGEOCH + MCDONALD.

A
  • Testing retroactive memory.
  • PP learnt list of 10 words until they could 100% recall.
  • Learnt a new list. (Synonyms, antonyms, unrelated adjectives, nonsense syllables, numbers, non-related).
  • Asked to recall original list.
    FINDINGS=
  • Interference strongest when memories are similar.
19
Q

EVALUATION OF INTERFERENCE THEORY.

A

+ R.S- MCGEOCH+ MCDONALD.
- OPPOSING THEORY- RETRIEVAL FAILURE.
- R.S- LAB EXP-LACK EV.

20
Q

RETRIEVAL FAILURE.

A
  • A form of forgetting that occurs when we do not have cues to access memory.
    ENCODING SPECIFICITY PRINCIPLE.
  • Tulving= Cue present at encoding isn’t present during recall.
  • Cue= Triggers memory. 2 TYPES.
21
Q

CONTEXT DEPENDANT CUES.

A
  • Recall depends on external cues e.g. place, weather.
    GODDEN + BADDLEY.
  • Learning + recall of deep sea divers.
  • 4 Conditions.
  • Best recall= Learnt + recall in same place (context dependant cues present).
22
Q

STATE DEPENDENT CUES.

A
  • Recall depends on internal cues e.g. emotional/ physical state (drugs/ drink).
    CARTER + CASSADAY.
  • Learning + recall using antihistamines.
  • 4 Conditions.
  • Best recall= state dependent cues present.
23
Q

EVALUATION OF RETRIEVAL FAILURE.

A

+ R.S - Godden+ Baddeley/ carter + Cassaday.
- QUALITY OF R.S.- Lacks ecological validity.
+ PRACTICAL APPLICATIONS- revision cues.
- Opposing theory- interference.

24
Q

EYE-WITNESS TESTIMONY.

A
  • Ability for someone to accurately recall events they have observed e.g. crime, accident.
25
FACTORS AFFECTING EWT.
- Anxiety. - Misleading questions.
26
MISLEADING INFORMATION.
- Incorrect info given to an ew. - LEADING QUESTIONS. - POST- EVENT DISCUSSIONS.
27
LEADING QUESTIONS.
- A question which suggests a certain answer due to the way it is phrasing. LOFTUS + PALMER. - 45 participants. - Questionnaire. - Pp watched a video of car crash from different p.o.v. - 'How fast was the car when they ___?' FINDINGS= - Crashed= lowest mph. - Smashed= highest mph. - Questions can distort memory + perception.
28
POST-EVENT DISCUSSION.
- More than one witness discussing events, influencing accuracy of recall. GABBERT ET AL. - 2 Experimental groups. - Watched clips from diff perspective. - One group discussed. FINDINGS= - 71% of pp who discussed recalled event sot seen. - 0% inaccurate recall in control group. - P.E.D causes inaccuracies in ewt.
29
ANXIETY- J+S.
JOHNSON + SCOTT. - Lab study. - Pp in waiting room. - Overheard either: conversation (low a) or argument + smashed glass (high a). - Man exits holding either: pen with grease or knife with blood. - Pp shown 50 photos + asked to identify. - Low anxiety= best recall. - Weapon focus affect= Ew only focuses on 'weapon' + not other objects.
30
ANXIETY DEFINITION.
- State of emotional and physical arousal.
31
ANXIETY- Y+C.
Yuille + Cutshall. - 13/21 witnesses of gun shop shooting interviewed immediately after + 5 months later. - Questioned on stress levels and any emotional issues. - Compared reports from both interviews. - Accuracy determined by no. of details. - Best recall= high anxiety.
32
EVALUATION OF ANXIETY.
+ R.S- Y+C/ J+S. - Quality of Y+C.- lacks control. - Quality of J+S.- lab. - Informed consent.
33
COGNITIVE INTERVIEWS.
- A method of interviewing e.w to help recall accurate memories. - Developed by Fisher + Gieselman. - Based on psychological principles. - Allows memories to be accessed using multiple techniques.
34
COGNITIVE INTERVIEW TECHNIQUES.
1. Report everything. 2. Reinstate the context. 3. Reverse the order. 4. Change perspective.
35
C.I - TECHNIQUE 1.
REPORT EVERYTHING. - Encourage to include every detail including those deemed unnecessary. - Trivial details may be important and help trigger others.
36
TECHNIQUE 2.
REINSTATE THE CONTEXT. - Mentally return to original crime scene. - Imagine environment. e.g. weather, visual, emotions.
37
TECHNIQUE 3.
REVERSE THE ORDER. - Recalled in a different chronological order. - Prevents reporting expectations of what happened.
38
TECHNIQUE 4.
CHANGE PERSPECTIVE. - Recall from diff p.o.v. - Prevents expectations. - Schemas could generate false info.
