Abstract:
The relevance of attentional measures to cognitive and social adaptive behaviour
was examined in an adolescent sample. Unlike previous research, the influence of both
inhibitory and facilitory aspects of attention were studied. In addition, contributions made
by these attentional processes were compared with traditional psychometric measures of
cognitive functioning.
Data were gathered from 36 grade 10 and 1 1 high school students (20 male and 16
female students) with a variety of learning and attentional difficulties. Data collection was
conducted in the course of two testing sessions. In the first session, students completed
questionnaires regarding their medical history, and everyday behaviours (the Brock
Adaptive Functioning Questionnaire), along with non-verbal problem solving tasks and
motor speed tasks. In the second session, students performed working memory measures
and computer-administered tasks assessing inhibitory and facilitory aspects of attention.
Grades and teacher-rated measures of cognitive and social impulsivity were also gathered.
Results indicate that attentional control has both cognitive and social/emotional
implications. Performance on negative priming and facilitation trials from the Flanker task
predicted grades in core courses, social functioning measures, and cognitive and social
impulsivity ratings. However, beneficial effects for academic and social functioning
associated with inhibition were less prevalent in those demonstrating a greater ability to
respond to facilitory cues. There was also some evidence that high levels of facilitation
were less beneficial to academic performance, and female students were more likely to
exceed optimal levels of facilitory processing. Furthermore, lower negative priming was

These findings provide support for neuropsychological models linking inhibition to
control of interference and arousal, and emphasize the fundamental role of attention in
everyday adolescent activities. The findings also warrant further investigation into the
ways which inhibitory and facilitory attentional processes interact, and the contextdependent
