Analyzing social perception of chronotypes within the stereotype content model

Area of Science:

• Psychology
• Social Psychology
• Chronobiology

Background:

• Social impressions and group stereotypes are often categorized along dimensions of warmth and competence.
• Chronotypes, referring to morning or evening preferences for activity, can influence social perceptions.

Purpose of the Study:

• To analyze social perceptions of morning and evening chronotypes using the stereotype content model.
• To investigate how individuals' own chronotypes influence their perceptions of others.

Main Methods:

• Utilized the stereotype content model framework to assess social perceptions.
• Surveyed 1277 participants using the Composite Scale of Morningness (CSM) and a social perception questionnaire.
• Selected 'pure' morning (M-types), intermediate (N-types), and evening (E-types) chronotypes for analysis.

Main Results:

• Morning types were perceived as significantly more competent and slightly warmer than evening types across the entire sample.
• Perceptions varied based on the perceiver's chronotype; only intermediate types' perceptions aligned with the general pattern.
• Morning-type perceivers showed strong ingroup favoritism, while evening-type perceivers viewed their ingroup as equally competent but warmer than morning types.

Conclusions:

• Social perceptions of chronotypes are a blend of shared societal stereotypes and ingroup-serving biases.
• Morning types are stereotyped as highly competent, influencing general perceptions.
• Individuals tend to view those with similar chronotypes more favorably, highlighting the role of ingroup bias in social cognition.
