Ostracism: Effects of Being Ignored Over the Internet
0 Views •
2023
Source: Peter Mende-Siedlecki & Jay Van Bavel—New York University Social ostracism is defined as being ignored and excluded in the presence of others. This experience is a pervasive and powerful social phenomenon, observed in both animals and humans, throughout all stages of human development, and across all manner of dyadic relationships, cultures, and social groups and institutions. Some have argued that ostracism serves a social regulatory function, which can enhance group cohesion and...

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...

Categories and Inductive Inferences

Source: Laboratories of Nicholaus Noles and Judith Danovitch—University of Louisville It might be possible for the human brain to keep track of each individual person, place, or thing encountered, but that would be a very inefficient use of time and cognitive resources. Instead, humans develop categories. Categories are mental representations of real things that can be used for a variety of purposes. For example, individuals can use the perceptual features of animals to place them into a given...

Characterizing microbial community has been a longstanding goal in environmental microbiology. Next-generation sequencing methods now allow for the characterization of microbial communities at an unprecedented depth with minimal cost and labor. We detail here our approach to sequence bacterial 16S ribosomal RNA genes using a benchtop sequencer.

Measuring Connectivity in the Primary Visual Pathway in Human Albinism Using Diffusion Tensor Imaging and Tractography

This manuscript describes deterministic and probabilistic algorithms for white matter (WM) reconstruction, used to examine differences in optic radiation (OR) connectivity between albinism and controls. Although probabilistic tractography follows the true course of nerve fibers more closely, deterministic tractography was run to compare the reliability and reproducibility of both techniques.
FAQs
Social categorization supplies the mental sorting process, whereas group identification reflects how strongly a person connects with a category. The first can organize perceptions of “us” and “them”; the second can make group-relevant norms, attitudes, and relationships more personally meaningful. Distinguishing these processes helps psychologists explain why simply recognizing a group may differ from actively identifying with it.
Shared norms guide expectations about acceptable conduct, influencing conformity, communication, and cooperation. They can coordinate members by clarifying how to interact, but they also shape responses to people outside the group. In psychological research, examining norms helps connect group membership with observable behavior and with broader processes such as leadership and collective action.
An attachment to a group can strengthen belonging, mutual support, and cooperation among members while also influencing evaluations of outsiders. When people organize social experience around in-group and out-group distinctions, attitudes and responses may become patterned by membership. This dual effect is important because the same social connection that supports collective action can also contribute to prejudice or unequal intergroup relations.
Research can examine how social categorization, group identification, and shared norms relate to attitudes, communication, cooperation, and responses to in-group or out-group members. It can then connect these processes with outcomes such as conformity, social support, leadership, prejudice, or collective action. This framework keeps individual experiences and intergroup relationships in the same analysis.
Within organizations and educational settings, group membership provides a framework for examining how shared norms and identification affect communication, cooperation, leadership, and belonging. The same perspective can be extended to culture and health behavior, where social environments may shape attitudes and actions. These applications connect psychological mechanisms to everyday institutions rather than treating behavior as purely individual.
Group membership helps explain how people coordinate around shared identities and norms, making collective action easier to understand. It also highlights how in-group and out-group responses may contribute to prejudice. Psychological research can use this connection to examine prejudice reduction alongside belonging, cooperation, and social support, linking efforts to improve intergroup relations with broader group processes.
