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...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Bias in Epidemiological Studies

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

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?

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...

Cognitive Dissonance

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Area of Science:

Public Health
Neuroscience
Sociology

Background:

Racial inequities in cognitive function are a persistent public health concern.
Evidence on the impact of racial discrimination on cognitive outcomes remains mixed.
Institutional discrimination may disproportionately affect cognitive health.

Purpose of the Study:

To examine the association between racial discrimination in institutional settings and cognitive function.
To strengthen the evidence base on discrimination's impact on cognition.
To identify potential intervention points for cognitive health disparities.

Main Methods:

Cross-sectional analysis of data from the Coronary Artery Risk Development in Young Adults (CARDIA) study (Waves 8 & 9).
Used the Experiences of Discrimination Scale for self-reported racial discrimination.
Employed ordinary least squares (OLS) and instrumental variable (IV) analyses, using skin color as an instrument.

Main Results:

Increased experiences of racial discrimination were associated with poorer performance on cognitive assessments.
Instrumental variable analysis showed a significant negative association between discrimination and auditory verbal learning.
Results indicate a potential link between lifelong exposure to racism and cognitive function.

Conclusions:

Racial discrimination, particularly within institutional contexts, is associated with diminished cognitive function.
Findings suggest that navigating a racialized society may contribute to cognitive inequities over the life course.
This research underscores the need for interventions addressing systemic racism to promote cognitive health equity.
