Effects of instruction on a divided visual-field task of face processing

Area of Science:

• Cognitive psychology
• Neuroscience
• Visual perception

Background:

• The left visual-field (LVF) advantage is a common finding in face recognition tasks.
• Cognitive strategies may interact with established visual processing biases.

Purpose of the Study:

• To investigate whether instructional strategies can alter the typical left visual-field advantage in face recognition.
• To examine the interplay between learning strategies, gender, visual field, and emotional valence in face perception.

Main Methods:

• A lateralized face recognition task was administered to 40 right-handed participants (20 men, 20 women).
• Participants used either a verbal or imagery strategy to memorize face pairs.
• Reaction times (RTs) and accuracy were recorded for emotional probe faces presented in the left or right visual field.

Main Results:

• Significant complex interactions were found involving gender, strategy, visual field, and emotion in RTs.
• A general left visual-field advantage was observed in accuracy and sensitivity.
• Instructional effects on the left visual-field advantage were primarily evident in reaction time data.

Conclusions:

• Cognitive instruction effects can modulate visual-field advantages in face recognition, particularly impacting reaction times.
• The findings highlight the dynamic interplay between cognitive strategies and basic perceptual biases.
• Further research is needed to confirm these complex interactions and establish causal relationships.
