High-Level and Low-Level Awareness01:19

High-Level and Low-Level Awareness

989
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...

Social Loafing

29.3K
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,...

Cognitive Dissonance

29.1K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Chunking and Rehearsal in Sensory Memory

818
Improving short-term memory can be achieved through techniques like chunking and rehearsal. Chunking involves organizing information into larger, more manageable units. This technique is particularly useful for information that exceeds the typical memory span of between five and nine items. For instance, logging into an online account with a password like "ta89vq0179gz" involves grouping letters and numbers into three chunks—ta89, vq01, and 79gz. It makes large amounts of...

Self-Discrepancy Theory

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.

Coping Strategies: Problem Focused01:27

Coping Strategies: Problem Focused

796
Coping strategies are methods people use to manage, tolerate, or reduce the effects of stressors. These strategies involve both behavioral and psychological actions to handle stressful situations. One common approach is problem-focused coping, which aims to change or eliminate the source of stress rather than merely addressing its consequences. This method involves taking direct action to resolve the issue causing stress.
For example, consider a student who struggles to understand their...

Summary
This summary is machine-generated.

Distracting information hinders learning on easy tasks but not difficult ones when students have a pending goal. This interference occurs because goal conflicts consume cognitive resources needed for learning.

Area of Science:

  • Cognitive Psychology
  • Educational Technology
  • Human-Computer Interaction

Background:

  • Students in educational hypermedia face distractions from interesting, task-irrelevant information.
  • Understanding when and why distractions impede learning is crucial for designing effective learning environments.

Purpose of the Study:

  • To investigate the conditions under which task-irrelevant information distracts students.
  • To examine the role of task difficulty and pending goals in distraction effects.

Main Methods:

  • Two experiments involving students learning probability theory with worked examples and solving problems.
  • Manipulation of task difficulty and the presence of interesting, task-irrelevant information.
  • Experiment 2 also manipulated a pending goal related to the irrelevant information.

Main Results:

  • Task-irrelevant information did not hinder performance in Experiment 1.
  • In Experiment 2, a pending goal led to performance decline on easy tasks but not difficult ones.
  • Students spent less time on relevant tasks and more on irrelevant ones with a pending goal during easy tasks.

Conclusions:

  • Distraction from interesting, task-irrelevant information primarily affects performance on easy tasks when a competing goal exists.
  • Cognitive resource depletion due to goal conflicts, rather than overt shifts in attention, likely explains performance decrements.
  • Implications for designing hypermedia to minimize goal conflicts and support focused learning.
