Memory for incidentally perceived social cues: Effects on person judgment

Area of Science:

• Psychology
• Social Psychology
• Cognitive Neuroscience

Background:

• Dynamic facial cues significantly impact social judgments during interactions.
• Subtle cues, like pupil dilation, can influence perceptions without conscious awareness.

Purpose of the Study:

• To investigate whether subtle, incidentally perceived dynamic cues, specifically pupil size changes, are encoded into memory.
• To determine if these encoded cues influence later judgments of an individual.

Main Methods:

• Participants observed individuals with dynamic changes in pupil size.
• Memory for these dynamic cues and subsequent social judgments were assessed.
• The influence of perceived trustworthiness and social context was examined.

Main Results:

• Changes in pupil size were encoded into memory under certain circumstances.
• These memories influenced later judgments of the observed individual.
• The impact of pupil size memory interacted with perceived trustworthiness and social context.

Conclusions:

• Subtle dynamic cues, such as pupil dilation, can be implicitly encoded and affect later social cognition.
• The influence of pupil size memory is modulated by individual differences and contextual factors.
