Strategies of Self-Presentation III: Self-Monitoring01:24

Strategies of Self-Presentation III: Self-Monitoring

Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...

High-Level and Low-Level Awareness

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...

Summary

The vigilance decrement, or reduced ability to detect critical events over time, was studied using a cognitive task. Results indicate attention lapses and guessing contribute to vigilance loss, though their impact on observed responses may be modest.

Area of Science:

  • Cognitive Psychology
  • Human Factors Engineering
  • Computational Neuroscience

Background:

  • The vigilance decrement is a well-documented decline in monitoring ability over time.
  • Previous research primarily used sensory tasks, yielding inconsistent results for cognitive vigilance tasks.
  • Cognitive vigilance tasks require judgments of symbolic characteristics, posing unique challenges.

Purpose of the Study:

  • To investigate the robustness and nature of the cognitive vigilance decrement.
  • To develop and apply a computational model for a novel cognitive monitoring task.
  • To analyze changes in attentional states and their impact on performance over time.

Main Methods:

  • Participants performed a novel monitoring task requiring estimation of central tendency from three-digit readings.
  • Signal detection theory-based computational models were used to analyze performance data.
  • Data from the initial and final 4-minute blocks of trials were analyzed to assess changes over time.

Main Results:

  • Model parameter estimates revealed an increased attentional lapse rate and decreased positive guess rate over time.
  • A decrease in internal processing noise was also observed.
  • These latent changes had modest and partially offsetting effects on observable response rates.

Conclusions:

  • Attention lapses and negative guessing tendencies are common contributors to vigilance decrement in both sensory and cognitive tasks.
  • Despite underlying changes in attentional states, the impact on observed responses can be small.
  • The study provides insights into the mechanisms underlying cognitive vigilance and its decline.
