Q

what is the role of the sensory register

A

this is where iconic and econic stores with very brief duration, high capacity and are transferred by attention

Q

describe the STM store in the MSM model

A
  • limited capacity
  • limited duration store
  • mainly acoustic coding
  • transfer to LTM by rehearsal

Q

what did baddelys research suggest and give an evaluation point

A

that acoustic memory occurs in the STM and semantic in the LTM
Evaluation point- lack of extrenal validity as word list had no personal significance

Q

what is capacity and who’s research supports it

A
  • AMOUNT OF INFORMATION THAT CAN BE HELD

- Jacobs research states that 9.3 digit could be remembered whilst 7.3 letters.

Q

what did millers research suggests

Q

what did bahricks study suggest with an evaluation point

A
  • recognition of faces after 15 year was 90%; recall was 60%
  • recognition dropped to 70% after 40 years.

Evaluation- higher external validity real life memories

Q

what are the 4 key parts of the working memory model

A
  1. central executive- co-ordinates slave systems and allocates resource- limited storage
  2. Phonological loop- auditory information, required maintenance rehearsal
  3. visuo spatail sketchpad- visual information with visual store and spatial arrangement
  4. episodic buffer- intergrates the process of slave systems and records order of events

Q

who’s research suggests that anxiety has a negative affect on recall

A

Q

describe the 2 types of interference

A

proactive- old memories disrupt new ones

retroactive- new memories that disrupt old ones

17
Q

what does Mcgoech and Macdonald theory states

A

similar words created more interference

18
Q

why do leading questions affect Eye witness testimony

A
  • response bias- no change to memory

- gabbert et al demonstrated effect calling it memory conformity where NSI is in invloved
