Stereotype Threat and Self-fulfilling Prophecies02:09

Stereotype Threat and Self-fulfilling Prophecies

38.4K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Stereotype Content Model02:16

Stereotype Content Model

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Factors Affecting Perception01:25

Factors Affecting Perception

1.8K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

91.1K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Confirmation Biases01:31

Confirmation Biases

6.4K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

The Representativeness Heuristic02:13

The Representativeness Heuristic

16.1K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Summary
This summary is machine-generated.

Group facial typicality influences social perception, but only when tasks require stereotype judgments. This impacts decision-making processes, affecting how we perceive others.

Area of Science:

  • Social Psychology
  • Cognitive Science
  • Social Cognition

Background:

  • Group composition significantly impacts social perception.
  • The precise mechanisms and conditions under which group characteristics influence stereotype-based responding remain unclear.

Purpose of the Study:

  • To investigate how task requirements moderate the effects of group facial typicality on stereotype-related social perception.
  • To explore the influence of group variability on people perception.

Main Methods:

  • Participants viewed same-sex groups varying in facial typicality (high/low femininity/masculinity).
  • Tasks involved either gender classification (group-irrelevant) or stereotype-status judgment (group-relevant).
  • Computational analysis using the Diffusion Model examined decision-making processes.

Main Results:

  • Facial typicality of groups only affected performance in the stereotype-status task.
  • Evidence accumulation was faster for targets following high-typicality groups.
  • High-typicality groups elicited stronger biases toward stereotypic responses.

Conclusions:

  • Task requirements are critical in determining when group facial typicality influences social perception.
  • Group variability affects people perception by modulating stimulus processing and response biases in decision-making.
