Social Facilitation01:04

Social Facilitation

35.9K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

In- and Out-Groups01:31

In- and Out-Groups

42.8K
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.

Robbers Cave04:49

Robbers Cave

14.7K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

452
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Frequency-dependent Selection01:21

Frequency-dependent Selection

22.9K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Summary

Negative emotions intensify visual crowding, making it harder to identify stimuli surrounded by negative flankers. However, negative targets are identified more easily when participants strongly associate emotions with stimuli.

Area of Science:

  • Visual perception
  • Cognitive psychology
  • Affective science

Background:

  • Visual crowding impairs peripheral stimulus identification.
  • The influence of emotion on visual crowding is not fully understood.
  • Evaluative conditioning can link neutral stimuli with emotional content.

Purpose of the Study:

  • To investigate how flanker and target emotion affect visual crowding.
  • To determine if emotional conditioning influences crowding effects.
  • To explore the interaction between emotion and early visual processing.

Main Methods:

  • Landolt rings were conditioned with neutral or negative images.
  • A visual crowding task assessed critical spacing for emotional stimuli.
  • Evaluative conditioning effects were measured in participants.

Main Results:

  • Negative flankers produced larger crowding effects than neutral flankers.
  • Strong evaluative conditioning led to smaller crowding effects for negative targets.
  • Emotional flankers and targets modulate visual crowding performance.

Conclusions:

  • Crowding effects are modulated by both flanker and target emotion.
  • High-level stimulus features, like emotion, can influence early perceptual processes.
  • Evaluative conditioning is a valuable method for studying emotion's impact on perception.
