Early attention and negative emotionality predict later cognitive and behavioural function

Abstract

Negative emotionality and poor attention may combine or interact as risk factors in development. Negative emotionality is considered a challenge for self-regulation, whereas good attention is a potential means of self-regulation. In the current study, composites of 1- and 2-year maternal ratings of negative emotionality and global ratings of observed attentiveness were predictors for 3.5-year cognitive and behavioural outcome for 75 children. Results of variable-based regression analyses indicated that early negativity and attentiveness predicted IQ and scores on a hyperactivity index; only negativity predicted a global measure of behaviour problems. Results of person-based analyses for groups formed by median splits on negativity and attention suggested that the More Negative/Less Attentive group had significantly poorer outcome than the other three groups combined (those with one or none of the two risk factors). Comparisons of mean differences also suggested a protective effect of greater attentiveness for more negative as opposed to less negative children for all outcomes. The results extend prior work in providing longitudinal data over the first 3 years and including both cognitive and behavioural outcomes.
