Visual set and anxiety in the Stroop phenomenon

Area of Science:

• Cognitive Psychology
• Psycholinguistics

Background:

• The Stroop phenomenon demonstrates interference in reaction time when processing conflicting stimuli.
• Anxiety levels can potentially modulate cognitive control and performance on tasks like the Stroop.

Purpose of the Study:

• To investigate the impact of visual set and anxiety on response latency within the Stroop task.
• To examine how different response conditions (word reading vs. color reporting) interact with Stroop interference and anxiety.

Main Methods:

• Utilized the Stroop phenomenon with three visual set conditions: congruent color, conflicting color, and no color.
• Measured response latency in two conditions: reading the color word and reporting the ink color of the word.
• Assessed participant anxiety using the Spielberger State-Trait Anxiety Inventory.

Main Results:

• Reporting the ink color resulted in significantly longer response latencies compared to reading the word across all participants.
• A significant interaction was observed between anxiety levels and the Stroop phenomenon.
• The medium-anxiety group exhibited the smallest difference between response conditions, indicating reduced Stroop interference.

Conclusions:

• Response modality (reporting color vs. reading word) significantly affects performance in the Stroop task.
• Anxiety modulates the Stroop interference effect, with medium anxiety levels showing the least interference.
• Visual set congruency influences performance, though not always significantly, suggesting its role in cognitive processing.
