Sensory Memory Characteristics

These flashcards summarize the key concepts related to sensory memory, focusing on iconic and echoic memory, their characteristics, and related theories.

Iconic Memory

The visual component of sensory memory with a high capacity for storage, lasting less than one second.

Masking Effect

Occurs when a new visual stimulus replaces the material currently in iconic memory, leading to decreased recall accuracy.

Partial Report Advantage

A phenomenon where recalling only part of a visual stimulus is possible if presented with a cue, affected by the presence of masking.

Representation in Iconic Memory

Stores both visual characteristics and semantic information of a stimulus simultaneously.

Echoic Memory

The auditory version of iconic memory; stores auditory information for about 100 milliseconds.

Decay in Echoic Memory

The loss of accurate auditory information after approximately 250 milliseconds.

Sensory Code

The way information is represented in echoic memory, processed in acoustic features organized in time.

Early Filter Theory

Suggests that all stimuli are processed at the physical level, but not all are semantically processed.

Late Filter Theory

Poses that both physical and semantic characteristics of stimuli are processed.

Switching Between Filter Models

The ability of the sensory system to use either early or late filter theories depending on task demands.

What are iconic memory characteristics

large capacity

Decay after 1 sec

Visual info can actively be erased by masking effect

stroes visual and semantic info

What are the characteristics of echoic memory?

-losses info through decay or throigh masking effect

info is represented as sensory code

Auditory info decays after 250 ms
