Self-Discrepancy Theory02:45

Self-Discrepancy Theory

19.0K
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

338
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,...

Role of Affect in Interpersonal Attraction01:24

Role of Affect in Interpersonal Attraction

239
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

The Influence of Affect on Cognition01:29

The Influence of Affect on Cognition

307
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect

232
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Background and Environment Affect Phenotype

7.8K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Summary
This summary is machine-generated.

Radiology resident performance declines during high-volume shifts and busy periods, leading to increased discrepancies in computed tomography (CT) interpretations. This highlights the need for careful staffing in residency programs.

Area of Science:

  • Radiology
  • Medical Education
  • Healthcare Management

Background:

  • On-call radiology residents interpret imaging studies.
  • Study volume may impact diagnostic accuracy.
  • Discrepancy rates are a key performance indicator.

Purpose of the Study:

  • To investigate the relationship between study volume and discrepancy rates for on-call radiology residents.
  • To assess the impact of total shift volume and real-time workload on resident performance.

Main Methods:

  • Retrospective analysis of 518 weekend call shifts.
  • Comparison of preliminary and final reports for discrepancies in abdomen-pelvis (AP) or chest-abdomen-pelvis (CAP) CTs.
  • Introduction of 'peristudy volume' to quantify real-time workload.

Main Results:

  • A significant increase in daily CT volume was observed between 2011 and 2015.
  • Discrepancies affecting short-term management occurred in 3.1% of reviewed CTs.
  • Higher total shift volume (≥51 CTs) and higher peristudy volume (≥6 CTs) were associated with increased odds of discrepancies.

Conclusions:

  • On-call radiology residents exhibit higher discrepancy rates during high-volume shifts and busy time-points.
  • These findings suggest that workload significantly influences resident performance.
  • Residency programs should consider these data for informed staffing decisions.
