Self-Regulation01:25

Self-Regulation

175
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.8K
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-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

222
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Control Systems01:10

Control Systems

1.7K
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

5.8K
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.

Locus of Control01:26

Locus of Control

155
Locus of control describes how individuals perceive the causes of events in their lives, influencing motivation and well-being. Introduced by Julian Rotter in 1954, it is categorized into internal and external locus of control.Internal Locus of ControlIndividuals with an internal locus of control believe their actions determine outcomes, fostering responsibility, self-efficacy, and motivation. For example, an employee may attribute career success to hard work. Research links this mindset to...

Summary

This study introduces a new model for effortful control, explaining mental fatigue during demanding tasks. It suggests that weakened neural network connectivity, reflecting the costs of goal-directed behavior, causes this fatigue.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Social Psychology

Background:

  • Effortful control is a resource-limited mechanism crucial for mental and physical tasks.
  • Mental fatigue arises from prolonged, high-demand activities.

Purpose of the Study:

  • To present an integrative model of effortful control.
  • To explain the neurophysiological basis of mental fatigue.

Main Methods:

  • Synthesizing findings from neuroscience, social psychology, and cognitive psychology.
  • Developing a theoretical model of effortful control.

Main Results:

  • Effortful control involves a limited set of interconnected processing units.
  • The effort signal modulates neural activity for task-relevant information selection.
  • Mental fatigue is attributed to intrinsic costs and weakened neural connectivity.

Conclusions:

  • The proposed model integrates behavioral and neurophysiological aspects of effortful control.
  • It offers a framework for understanding the costs of sustained goal-directed behavior.
  • Further research can explore effortful control at behavioral and neurophysiological levels.
