Effect of stress on field dependence
Perceptual and Motor Skills
|August 1, 1976
Summary
Stress significantly impacts visual perception, increasing field dependency and performance variability. These findings highlight stress
Area of Science:
- Psychology
- Perception
- Cognitive Science
Background:
- Field dependency is a key concept in Witkin's theory of perception and personality.
- Understanding how external factors like stress influence perceptual tasks is crucial.
Purpose of the Study:
- To investigate the effect of stress, induced by flicker conditions, on performance in the rod-and-frame test.
- To examine changes in field dependency and performance variability under stress.
Main Methods:
- Sixty subjects participated in the rod-and-frame test under both stress (flicker) and control (no flicker) conditions.
- Rod-and-frame scores and performance variability were measured and compared between conditions.
- Data were analyzed to assess the monotonic increase in scores and changes in variability during the stress session.
Main Results:
- Rod-and-frame scores were significantly higher under stress compared to the control condition.
- Scores demonstrated a monotonic increase throughout the session under stress.
- Both intra- and interindividual variability in performance consistently changed under stress.
Conclusions:
- Stress reliably influences field dependency, as evidenced by altered rod-and-frame test performance.
- The findings support the integration of stress as a significant variable in perceptual research.
- Results are discussed within the theoretical framework of Witkin's perception and personality model.
