Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.9K
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.

Self-Discrepancy and Its Effects01:29

Self-Discrepancy and Its Effects

312
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,...

Impact of Individuals on Individuals01:30

Impact of Individuals on Individuals

373
Human behavior is intricately shaped by social influences that arise from interactions with others in diverse contexts. These influences not only mold beliefs and attitudes but also drive the regulation of behaviors through both direct communication and observational learning. The study of these processes falls within the domain of social psychology, which seeks to understand how individuals are affected by and affect those around them.Mechanisms of Social InfluenceDirect social influence...

Electric Potential and Potential Difference01:16

Electric Potential and Potential Difference

5.7K
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...

Difference from Background: Limit of Detection

8.3K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Identifying Statistically Significant Differences: The F-Test01:14

Identifying Statistically Significant Differences: The F-Test

3.7K
The F-test is used to compare two sample variances to each other or compare the sample variance to the population variance. It is used to decide whether an indeterminate error can explain the difference in their values. The underlying assumptions that allow the use of the F-test include the data set or sets are normally distributed, and the data sets are independent of each other. The test statistic F is calculated by dividing one variance by another. In other words, the square of one standard...

Summary
This summary is machine-generated.

This study found that better performance on a pursuit rotor task predicted faster detection of lost control in a visuomotor task. This suggests motor control skills may influence the sense of agency.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Human-Computer Interaction

Background:

  • The sense of agency involves perceiving control over one's actions and their outcomes.
  • Understanding factors influencing the sense of agency is crucial for various fields, including human-computer interaction and clinical psychology.
  • Visuomotor discrepancies, where actions do not produce expected sensory feedback, can challenge the sense of agency.

Purpose of the Study:

  • To investigate the relationship between sensitivity to visuomotor discrepancies and various psychological traits.
  • To determine if psychological constructs like locus of control, impulsiveness, need for cognition (NFC), and schizotypy are associated with the ability to detect loss of control.
  • To explore predictors of response times to visuomotor discrepancies.

Main Methods:

  • College-aged adults completed a computerized tracking task requiring them to control a cursor.
  • Participants responded to trials where the cursor became unresponsive, indicating a loss of control.
  • Response times (RTs) to loss of control were measured, alongside performance on cognitive and personality assessments.

Main Results:

  • Bivariate correlations between RTs to loss of control and higher-order cognitive/personality traits were not significant.
  • Step-wise regression revealed that better performance on the pursuit rotor task predicted faster RTs to loss of control.
  • This predictive relationship held even when controlling for age, signal detection, and NFC.

Conclusions:

  • Sensitivity to visuomotor discrepancies is not strongly associated with common measures of locus of control, impulsiveness, or schizotypy.
  • Motor control abilities, specifically performance on the pursuit rotor task, appear to be a significant predictor of detecting loss of control.
  • These findings contribute to multifactorial models of the sense of agency, highlighting the role of motor performance.
