Memory Types and Sperling's Experiments

Questions and Answers

What is the duration of iconic memory?

200-500 milliseconds

What was the difference between Sperling's Full Report and Partial Tasks?

In Full Report task participants had to recall the full set of letters; in the Partial Report task participants only had to recall one row of letters

Study Notes

Memory Types

Iconic memory lasts between 200-500 milliseconds.
Echoic memory lasts approximately 4 seconds, making it longer than iconic memory.
Sensory memory supports the ability to continue processing a stimulus after it has vanished.

Sperling's Experiments

Sperling's Full Report task requires recalling an entire set of letters.
The Partial Report task only asks participants to recall one row of letters.
Recall from the Partial Report task demonstrated that longer delays between letter presentation and recall cues result in poorer performance, indicating the brief duration of iconic memory.

Memory Effects

The Primacy effect refers to better recall of the first few items in a sequence, but it is false to state this occurs because these items remain in working memory.
A serial position curve in experiments with distractor tasks shows high recall for the initial items and low recall for those in the middle or end of a list.
The recency effect describes the phenomenon of recalling the last few presented items more easily.

Working Memory Strategies

To retain a seven-digit passcode temporarily, repeating it to oneself enhances working memory retention.

Long-term Memory Challenges

Anterograde amnesia primarily affects recall of the first few items on a list due to difficulty forming long-term memories.

Implicit Bias

Implicit bias is characterized by biases that occur without conscious awareness.
Implicit attitudes, beliefs, and stereotypes are quickly accessed due to cultural internalization.
Explicit biases can differ significantly from implicit ones.

IAT (Implicit Association Test)

The IAT measures implicit bias through the analysis of response time differences.
In an IAT addressing attitudes towards disabilities, the stereotype consistent category for "grief" would be associated with "disabled" or "bad."
