Neuroticism, practice, and sex differences in a digit-symbol task

Area of Science:

• Cognitive Psychology
• Educational Psychology

Background:

• Understanding factors influencing cognitive performance is crucial for academic success.
• Previous research suggests a complex relationship between anxiety, practice methods, and learning.

Purpose of the Study:

• To investigate the effects of sex, practice distribution, and neuroticism (anxiety levels) on cognitive performance in a digit-symbol coding task.
• To examine potential interactions between these factors and learning over multiple trials.

Main Methods:

• 136 university students completed a digit-symbol coding task.
• A factorial analysis of variance was employed to analyze data across sex, practice type (distributed vs. massed), trial number (1-10), and neuroticism levels.

Main Results:

• Significant learning effects were observed across trials.
• Females demonstrated superior performance compared to males.
• Anxiety exhibited an inverse U-shaped relationship with performance under massed practice, with medium anxiety levels correlating with better outcomes.

Conclusions:

• Cognitive performance is influenced by sex and learning over time.
• Anxiety can impair performance, especially under high-pressure (massed practice) conditions, with moderate anxiety potentially being optimal.
