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...

Implicit Personality Theories

Implicit Personality Theories

Implicit personality theory explains how individuals make assumptions about the relationships between personality traits, behaviors, and character types. When people learn that someone possesses a particular trait, they tend to infer the presence of other related characteristics, forming a cohesive impression. This cognitive shortcut plays a crucial role in social interactions and interpersonal judgments.Central Traits and Their InfluenceSolomon Asch's seminal 1946 study highlighted the power...

Deindividuation

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Personality Disorders: Paranoid and Schizoid

Personality Disorders: Paranoid and Schizoid

Personality disorders represent enduring cognition, affect, and behavior patterns that significantly deviate from societal norms. These maladaptive traits often lead to difficulties in various domains, including interpersonal relationships, occupational settings, and overall psychological well-being. Paranoid personality disorder and schizoid personality disorder are two distinct conditions marked by odd or eccentric behavior.

Self-Presentation: Self-Monitoring and Self-Handicapping

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...

Theory of Attribution II: Kelley's Covariation Theory

Theory of Attribution II: Kelley's Covariation Theory

Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus: Comparing...

Summary

Patients with persecutory delusions may use high explicit self-esteem to defend against low implicit self-esteem. However, their overall self-esteem remains lower than in healthy individuals.

Area of Science:

Psychology
Psychiatry
Clinical Neuroscience

Background:

Theorized link between persecutory delusions and low implicit self-esteem, contrasted with normal/high explicit self-esteem.
Inconsistent empirical evidence regarding the relationship between delusions and self-esteem levels.

Purpose of the Study:

To investigate the theory that persecutory delusions serve as a defense against low implicit self-esteem.
To re-evaluate the relationship between implicit and explicit self-esteem in patients with persecutory delusions using the Implicit Association Test.

Main Methods:

Utilized the Implicit Association Test (IAT) to assess implicit self-esteem.
Employed the Rosenberg Self-Esteem Scale to measure explicit self-esteem.
Studied 23 schizophrenic patients (13 with persecutory delusions), 41 healthy controls, and 14 depressed controls.

Main Results:

Schizophrenic patients exhibited reduced implicit and explicit self-esteem compared to healthy controls.
Patients with persecutory delusions showed higher explicit self-esteem than non-paranoid patients.
Explicit self-esteem in patients with persecutory delusions was still lower than in healthy participants.

Conclusions:

Findings offer partial support for the defense mechanism theory linking persecutory delusions to low implicit self-esteem.
The role of 'feeling of personal significance' in elevating self-esteem in paranoid schizophrenia warrants further investigation.
Abnormal attributional styles may contribute to converting low self-esteem into higher explicit self-esteem.
