memory

week 9

sensory representations

information that is represented in one of the sense modalities

verbal representations

information represented in words

sensory registers

memory systems that hold info. for a very brief period of time

short-term memory

memory for info. that is available to consciousness for roughly 20-30 secs

• aka ‘working memory’

rehearsal

repeating/studying info. to retain it in memory

maintenance rehearsal

the process of repeating info. over and over to maintain it momentarily in STM

long-term memory

memory for facts, images, thoughts, feelings that may last for life time

retrieval

bringing info. from LTM into STM

serial position effect

a tendency to remember information towards the beginning and end of a list rather than in the middle

modules

discrete but interdependent processing units responsible for different kinds of remembering

memory

change in the brain/mind following experience

episodic buffer

a system that temporarily stores visual and auditory info. from LTM

phonological

represents a temporary store of mainly verbal info. together w/ a rehearsal mechanisms

chunking

the process of organizing info. into small, meaningful bits to aid memory

declarative memory

refers to memory for facts and events

procedural memory

refers to ‘how to’ knowledge of procedures or skills.

semantic memory

refers to general world knowledge or facts

e..g NaCl is the chemical formula for table salt

• aka generic memory

episodic memory

consists of memories of particular events, rather than general knowledge

explicit memory

conscious recollection of facts and event s

implicit memory

refers to memory that is expressed in behaviour but does not require conscious recollection

e.g. such as tying a shoelace.

recognition

refers to the explicit sense or recollection that something currently perceived has been previously encountered or learned

priming effects

the processing of specific info. is facilitated by prior exposure to the same info.

retrospective memory

memory for events that have already occured

prospective memory

memory for things that need to be done in the future
