It is easier to perform two tasks at the same time if

one is processed by the visuospatial sketch pad and one is processed by the phonological loop.

The capacity of short-term memory is about

somewhat small, holding only about seven items at one time.

Primacy effect

subjects are more likely to remember words in the beginning of a sequence

Jenkins and Russell (1952) presented a list of words like "chair, apple, dish, shoe, cherry, sofa" to participants. In a test, participants recalled the words in a different order than the order in which they were originally presented. This result occurred because of the

tendency of objects in the same category to become organized.

retroactive interference

the disruptive effect of new learning on the recall of old information

Autobiographical memories can involve both episodic and semantic content.

Baddeley s 1975

Best recall occurred when encoding retrieval occurred in the same place

The process of acquiring information and transforming it into long-term memory is called ____________.

Encoding

Explicit (Conscious)

Episodic (personal events), Semantic (facts, knowledge)

Short Term Memory

Holds five to seven items for about 15 to 20 seconds

Bransford and Johnson (1972)

How does organizing information effect coding?• Passage presented was too difficult to remember

Implicit (Not Conscious)

Procedural Memory, Priming, Conditioning

Baddeley's Working Memory Model

a more complex model than just passive STM; includes a phonological loop, visuospatial working memory, and the central executive

Slamecka and Graf (1978)

active learning is more effective than passive learning

amnesia that occurs for events after an injury

Sensory memory

Clive Wearing lost his ability to form new memories when he contracted viral encephalitis, which destroyed _________.

hippocampus

Longterm memory

Neuropsychological evidence indicates that short- and long-term memories are probably

caused by different mechanisms that act somewhat independently.

Miller

chunking

The research by Ericsson and colleagues (1980) examined the ability of a college student to achieve amazing feats of memory by having him remember strings of random digits that were recited to him. They found that this student used his experience with running times to help him retain these strings of numbers. The significance of this finding was that

chunking requires knowledge of familiar patterns or concepts.

The phonological loop

consists of the phonological store and the articulatory rehearsal process

The results of the the serial position curve shows that delaying the memory test for 30 seconds

decreases the recency effect.

Control Processes

dynamic processes associated with the structural features that can be controlled by the person and may differ from one task to another

What's one of the reason why people use chunking?

increase the efficiency of short-term memory.

Donald Hebb (1948) proposed that synaptic consolidation is one of the mechanisms that allows the brain to have physical changes that reflect the learning of new memories. These changes occur over time and include _______________.

increased firing in the neurons and greater number of identations at the axon terminals.

Sperling's experiment he showed participants a display with rows of letters. In one of the variations of his study, he delayed the partial report. This provided evidence showing that

information in sensory memory fades within one or two seconds.

procedural

central executive

pulls information from long-term memory and coordinates the activity of the phonological loop and visuospatial sketch pad by focusing on specific parts of a task and deciding how to divide attention between different tasks

Participants were given 2 tasks1. Read words and recall as many as possible2. Read words, repeat "the", recall as many as possible • Word Length Effect: Short items are remembered more easily than longer items • Articulatory Suppression: Rehearsal is prevented by having the participant repeat an unrelated word • Results: Having the person rehearse the, the, the reducedrehearsal advantage

Alverez and Cavanaugh (2004)

Similar experiment to Luck and Vogel (1997) Wanted to measure shot term memory capacity • The greater the amount of information, the fewer the number of items that can be stored in (visual) short-term memory
