Forming and canceling everyday intentions: implications for prospective remembering.

Area of Science:

• Cognitive Psychology
• Human Memory
• Decision Making

Background:

• The intention superiority effect (ISE) demonstrates faster processing for intended tasks versus neutral or canceled ones.
• Previous research explored the ISE, but less is known about its manifestation under naturalistic, self-initiated conditions.

Purpose of the Study:

• To investigate the intention superiority effect (ISE) under naturalistic conditions with self-initiated, personally relevant intentions.
• To examine how intention cancellation and the expectation of task information influence response times.

Main Methods:

• Participants self-initiated prospective memory tasks presented as preparatory tasks.
• Lexical decision tasks were used to measure response times to intended, canceled, and neutral items.
• Experiments manipulated intention presence, cancellation, and the expectation of written task descriptions.

Main Results:

• Faster response times were observed for intended items compared to canceled items in experimental groups.
• No significant difference in response time was found between two sets of canceled items in a control group.
• When intention was paired with the expectation of a written description, no reliable difference in response time was observed compared to canceled items.

Conclusions:

• The intention superiority effect is observable under naturalistic conditions with self-initiated intentions.
• Facilitatory and inhibitory processes likely underlie the management of multiple intentions in everyday life.
• The expectation of external task information may modulate the intention superiority effect.
