Self-Discrepancy Theory02:45

Self-Discrepancy Theory

17.9K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Social Proof00:52

Social Proof

24.9K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Relationship Formation

28.5K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Social Facilitation01:04

Social Facilitation

29.0K
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.

Social Loafing01:37

Social Loafing

29.3K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Psychological and Sociocultural Causes of Schizophrenia01:29

Psychological and Sociocultural Causes of Schizophrenia

977
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Summary
This summary is machine-generated.

Individuals with aphantasia show brain activity during visual imagery attempts, but these neural patterns differ from perception. This suggests transformed, non-conscious representations in the early visual cortex.

Area of Science:

  • Neuroscience
  • Cognitive Psychology

Background:

  • Aphantasia is a condition characterized by the inability to voluntarily create visual imagery.
  • Previous research has explored the neural underpinnings of visual imagery in typical individuals.

Discussion:

  • Addressed commentary on findings regarding unconscious imagery.
  • Early visual cortex activity in aphantasia may represent transformed or non-conscious information.

Key Insights:

  • Individuals with aphantasia exhibit stable, content-specific activation in the early visual cortex during imagery attempts.
  • Neural representations during imagery attempts differ from perception in aphantasia, evidenced by failed cross-decoding.
  • These findings challenge traditional views on the necessity of conscious visual experience for neural representation.

Outlook:

  • Further research into the nature of non-conscious representations in the visual cortex.
  • Exploring the implications for theories of consciousness and mental imagery.
