Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.5K
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.

Self-Discrepancy and Its Effects01:29

Self-Discrepancy and Its Effects

41
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Introspection01:29

Introspection

21
Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...

Confirmation Biases01:31

Confirmation Biases

7.4K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

92.3K
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...

Stereotype Content Model02:16

Stereotype Content Model

14.9K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Area of Science:

  • Neuroscience
  • Psychology
  • Human Physiology

Background:

  • Interoceptive accuracy, sensing internal body signals, is crucial for health.
  • Disruptions in interoception are linked to various mental and physical health issues.
  • Existing research on sex differences in interoceptive accuracy is inconsistent.

Purpose of the Study:

  • To systematically investigate sex differences in interoceptive accuracy.
  • To analyze accuracy across cardiac, respiratory, and gastric interoceptive domains.
  • To resolve ambiguity in previous findings regarding sex-based interoceptive variations.

Main Methods:

  • Conducted a meta-analysis of 93 eligible studies, reviewing 7956 abstracts.
  • Focused on interoceptive tasks measuring cardiac, respiratory, and gastric functions.
  • Calculated effect sizes to quantify the magnitude of sex differences.

Main Results:

  • Males exhibited significantly higher interoceptive accuracy in cardiac tasks.
  • No significant sex difference in interoceptive accuracy was observed for gastric tasks.
  • Findings for respiratory interoceptive accuracy were inconclusive, showing mixed results.

Conclusions:

  • Sex differences in interoceptive accuracy may exist, particularly in cardiac domains.
  • Inconsistencies in respiratory and gastric domains warrant further investigation.
  • Methodological considerations, including physiological factors, are important for future research.
