[Factorial structure of the executive functions in young university students].

INTRODUCTION

Several studies have proposed a multiple dimensional theoretical model for executive function.

OBJECTIVE

To identify the factor structure of the executive function in a sample of young university students of different modalities of learning in their careers.

METHODS

100 participants of both sexes, age 16 to-21-year old and normal Full Scale IQ were selected in a randomized and representative approach from private universities of Medellin Colombia. They were student of verbal, visuospatial and mathematical careers. A executive function assessment battery were applied, which included: Wisconsin Card Sorting Test (WCST), Trail Making Test (TMT) A and B, verbal fluency test (FAS) by phonologic and semantic guides, and Stroop test.

RESULTS

A structure of four factor was found, which explained 74.9% of variance. Factors were: 1. Organization and flexibility, which explained 26.6% of variance; 2. Processing speed, 19.7%; 3. Inhibitory control, 15.1%; and 4. Verbal fluency 13.4%.

CONCLUSION

A multiple factor structure of the executive function in young university students was demonstrated.
