Theory of Attribution II: Kelley's Covariation Theory01:29

Theory of Attribution II: Kelley's Covariation Theory

295
Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus:...

The Behavioral Perspective on Personality01:19

The Behavioral Perspective on Personality

647
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

5.6K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Variability: Analysis01:11

Variability: Analysis

346
Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

Attribution Theory00:56

Attribution Theory

13.6K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

Fundamental Attribution Error01:14

Fundamental Attribution Error

13.5K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Summary
This summary is machine-generated.

Behavioral variability is crucial for understanding perception-action systems, offering insights into motor control mechanisms. Studying this variability reveals key features of underlying processes, challenging assumptions about randomness and determinism.

Area of Science:

  • Motor control and perception-action systems research.
  • Exploration of behavioral variability in scientific inquiry.

Background:

  • Traditionally, behavioral variability was often seen as noise or an impediment to research.
  • Recent perspectives highlight variability's potential to reveal underlying mechanisms.

Purpose of the Study:

  • To review concepts of variability and determinism in motor behavior.
  • To underscore the importance of variability as a key strategy in studying perception-action systems.

Main Methods:

  • Tutorial review of variability and determinism concepts.
  • Analysis of variability in postural and rhythmic movements.

Main Results:

  • Variability in motor behaviors provides crucial insights into underlying control mechanisms.
  • Identified specific blends of noise and determinism (piecewise determinism).

Conclusions:

  • Variability is not necessarily random, and controllability does not imply pure determinism.
  • Lessons from motor behavior variability may extend to other perceptual domains.
