Ch 5 Short Term And Working Memory Flashcards

1
Q

Modal model of memory

A

Processing information through a series of stages, including short-term and long-term memory. It is called the modal model because it includes many features of modals of the time.

Q

Structural features

A

Types of memory indicated by boxes in models of memory. In the modal model, the types are sensory, short term, and long term.

Q

Persistence of Visio.

A

The continued perception of light for a fraction of a second after the original light stimulus has been extinguished. Perceiving a trail go light.

Q

Short term memory

A

A memory mechanism that can hold informations for a brief period of time, usually 30 seconds. Unless rehearsed.

16
Q

Phonological loop

A

The part of working memory that holds and processes verbal and auditory information.

17
Q

Phonological store

A

Components of the phonological loop of working memory that holds a limited amount of verbal and auditory information for a few seconds.

18
Q

Articulatory rehearsal process

A

Rehearsal process involved in working memory that keeps items in the phonological store from decaying.

19
Q

Visual sketch pad

A

Holds visual and spatial information.

20
Q

Central executive

A

The part of working memory that coordinates the activity of the phonological loop and the visual sketch pad. The “traffic cop” of the working memory system.

21
Q

Phonological similarity effect

A

An effect that occurs in when letters or words that sound similar are confused. For example t-p are two similar sounding letters that could be confused.

22
Q

Word length effect

A

The notion that it is more difficult to remember a list of long words than a list of short words.

23
Q

Articulatory suppression

A

Interference with operation of the phonological loop that occurs when a person repeats an irrelevant word such as “the” while carrying out a task that requires the phonological loop.

24
Q

Visual imagery

A

A type of mental imagery involving vision, in which an image is experienced in the absence of visual stimulation.

25
Mental rotation
Rotating an image of an object in the mind.
26
Preservation
Difficulty in switching from one behaviour to another, which can hinder a person’s ability to solve problems that require flexible thinking.
27
Episodic buffer
A component added to Baddeley’s original memory model that serves as a backup store, it holds information longer and has greater capacity then the phonological loop or visual loop.
28
Delayed-response task
A task in which information is provided, a delayed is imposed, and then memory is tested. This task is used to study short-term memory.
29
Activity-silent working memory
Short term changes in neural network connectivity that has been hypothesized as a mechanism of holding information in working memory.
30
Reading span test
The test used by daemon and carpenter to measure reading span
31
Reading span
It is the number of 13-16 word sentences that a person can read and then correctly remember the last words of all the sentences.
32
Event related potential
An electrical potential, that reflects the response of many thousands of neuron’s near that electrode that fire together.
