Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

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 are...

Stereotype Content Model

Stereotype Content Model

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 categorization, a person will feel...

Stereotype Threat and Self-fulfilling Prophecies

Stereotype Threat and Self-fulfilling Prophecies

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...

In- and Out-Groups

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Confirmation Biases

Confirmation Biases

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?

Attribution Theory

Attribution Theory

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958). An internal factor is an...

Summary

Animals use time-place discrimination to find resources based on when and where they are available. This behavior is influenced by internal biological clocks, including circadian systems, and may require a unified timing theory.

Area of Science:

Behavioral Ecology
Chronobiology
Neuroscience

Background:

Environmental pressures drive the evolution of resource-finding behaviors.
Time-place discrimination is the ability to exploit resources based on temporal and spatial cues.

Purpose of the Study:

Review examples and theoretical issues in time-place discrimination.
Examine limitations imposed by circadian systems on timing performance.
Discuss research broadening the understanding of interval timing and memory.

Main Methods:

Literature review of time-place discrimination studies.
Analysis of theoretical and conceptual frameworks for behavioral timing.
Examination of empirical evidence on interval timing mechanisms.

Main Results:

Circadian systems influence time-place performance, but timing extends beyond circadian entrainment.
Both long (16-21 h) and short (1-3 min) intervals appear to be timed by endogenous oscillators.
Memory for event occurrence (when and where) may rely on circadian representations.

Conclusions:

A unified theory of timing is needed to account for the encoding of individual event times.
Timing mechanisms may involve multiple oscillators across different interval ranges.
Understanding these mechanisms is crucial for explaining adaptive behavior under environmental constraints.
