Working Memory01:24

Working Memory

387
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

High-Level and Low-Level Awareness

293
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Optimal Arousal Theory01:23

Optimal Arousal Theory

231
The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Social Loafing01:37

Social Loafing

34.8K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Lazarus's Cognitive Appraisal Theory01:20

Lazarus's Cognitive Appraisal Theory

314
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

Summary

Increased whole-day workload may impair next-day cognitive function, specifically visual processing speed. Sustained attention was not significantly affected, indicating a need for further research with larger samples.

Area of Science:

  • Occupational Health
  • Cognitive Psychology
  • Endocrinology

Background:

  • Workload, encompassing the entire day, can influence cognitive abilities beyond work periods.
  • Understanding the impact of daily workload on cognitive performance is crucial for worker well-being and productivity.

Purpose of the Study:

  • To investigate the association between whole-day workload and next-day cognitive performance in workers with type 1 diabetes.
  • To examine the effects of workload on visual processing speed and sustained attention.

Main Methods:

  • Dynamic structural equation modeling was used to analyze data from 56 workers over two weeks.
  • Participants completed daily workload surveys and frequent cognitive tests via smartphone, enhancing ecological validity.
  • Cognitive tests assessed visual processing speed and sustained attention.

Main Results:

  • Higher whole-day workload was associated with a significant decrease in next-day mean processing speed (standardized estimate = -0.10).
  • The association between workload and processing speed showed a non-significant trend in a more complex model.
  • No significant association was found between whole-day workload and next-day mean sustained attention ability.

Conclusions:

  • A single day of increased workload may negatively impact subsequent processing speed.
  • Future research with larger sample sizes is recommended to confirm these findings.
  • The study highlights the potential cognitive consequences of daily workload in individuals with type 1 diabetes.
