Effects of extraversion, anxiety, and sex on children's verbal fluency and coding task performance

Area of Science:

• Child Psychology
• Cognitive Neuroscience
• Educational Psychology

Background:

• Understanding the interplay between personality traits (extraversion, anxiety) and cognitive performance in children is crucial for educational and clinical settings.
• Previous research has primarily focused on adult populations, leaving a gap in knowledge regarding developmental differences.

Purpose of the Study:

• To investigate the influence of extraversion and anxiety on verbal fluency and nonverbal coding tasks in children and adolescents.
• To examine potential sex differences in the relationship between these personality traits and cognitive performance.

Main Methods:

• Participants: 78 boys and 71 girls (ages 8-18).
• Measures: Junior Eysenck Personality Inventory, Children's Manifest Anxiety Scale, verbal fluency tasks (simple and complex), and the Wechsler Intelligence Scale for Children (WISC) coding subtest.
• Design: Group assignment based on personality and sex scores.

Main Results:

• Extraverted children outperformed introverted children on both verbal fluency and coding tasks, irrespective of sex.
• Anxiety significantly impacted girls' performance on the complex verbal fluency task, but not boys' performance.
• No significant effect of anxiety was observed on the simple verbal fluency or coding tasks for either sex.

Conclusions:

• Extraversion appears to be a significant predictor of cognitive performance in children across verbal and nonverbal domains.
• Anxiety's impact on cognitive function may be sex-specific, particularly for more complex tasks.
• Findings suggest developmental continuity in the relationship between personality, anxiety, and cognitive abilities from childhood to adulthood.
