Creating the Minimal Group Paradigm

Source: Julian Wills & Jay Van Bavel—New York University The study of intergroup relations, such as prejudice, conflict, and discrimination, has always been a central topic in social psychology. Does discrimination stem from competition with other groups, a history of conflict, or derogatory stereotypes? Despite an abundance of real-world examples, the ingredients that lead to intergroup discrimination are often unclear. To help solve this problem, a group of psychologists created "minimal...

We discussed the synthesis of individual graphitic nanocups using a series of techniques including chemical vapor deposition, acid oxidation and probe-tip sonication. By citrate reduction of HAuCl4, the graphitic nanocups were effectively corked with gold nanoparticles due to the chemically reactive edges of the cups.

This video shows the resident-intruder paradigm in rats. This test is a standardized method to measure offensive aggression, defensive behavior and violence in a semi-natural setting. The use of the paradigm for social stress experiments is explained as well.
FAQs
Visibility of the hiding event helps separate memory for the location from reliance on current visual information. When subjects watch the reward placement, accurate selection can reflect retention of its spatial position. Altering visibility tests whether performance depends more on remembered location or cues available during the search. This comparison is especially informative when the arrangement changes across trials.
Chance performance provides a baseline for interpreting successful retrieval. If subjects select the correct cup more often than expected by chance, their choices suggest the use of information from the trial rather than random selection. Comparing observed accuracy with this baseline helps researchers determine whether spatial memory, attention, or another measured process contributes meaningfully to performance.
Choice latency shows how quickly a subject commits to a cup, whereas errors identify unsuccessful searches. Together, these measures distinguish fast and accurate performance from choices that are slow, uncertain, or frequently incorrect. Error patterns can also provide evidence relevant to inhibitory control, particularly when subjects must avoid previously selected or visually competing locations.
Using the same core search challenge across developmental stages or species allows researchers to compare accuracy, latency, and errors under corresponding conditions. Differences may indicate variation in spatial memory, attention, decision-making, or inhibitory control. Such comparisons are most informative when researchers also consider how changes in cup arrangement and visibility affect each group’s performance.
A typical trial uses four visually similar cups, places a reward beneath one cup, and establishes whether the subject can observe that placement. The cups then serve as competing search locations, and the subject’s selected cup is recorded. Researchers typically summarize retrieval accuracy, choice latency, and errors across trials or experimental conditions.
Researchers can vary the arrangement of the cups and the visibility of the hiding event while keeping the basic search problem comparable. These changes test whether subjects rely on stable spatial memory, visual cues, or information retained after the reward is hidden. Comparing performance across conditions reveals how environmental information influences search accuracy and decision-making.
The paradigm can examine how subjects remember locations, allocate attention, make choices, and inhibit unproductive responses. Researchers can use retrieval success, chance comparisons, latency, and errors to evaluate these processes across developmental stages, species, or experimental conditions. Its value comes from linking a controlled object-search task with measurable behavioral outcomes rather than relying on a single performance score.
