Adolescents’ inhibitory control: keep it cool or lose control
2018
Inhibitory control(i.e., the ability to resist automatisms,
temptations, distractions, or interference and to adapt to conflicting situations) is a determinant of cognitive and socio-emotional development. In light of the discrepancies of previous findings on the development of
inhibitory controlin affectively charged contexts, two important issues need to be addressed. We need to determine (a) whether cool
inhibitory control(in affectively neutral contexts) and
hot
inhibitory control(in affectively charged contexts) follow the same developmental pattern and (b) the degree of specificity of these two types of
inhibitory controlat different ages. Thus, in the present study, we investigated the developmental patterns of cool and
hot
inhibitory controland the degree of specificity of these abilities in children, adolescents and adults. Typically developing children, adolescents, and adults performed two Stroop-like tasks: an affectively neutral one (Cool Stroop task) and an affectively charged one (
HotStroop task). In the Cool Stroop task, the participants were asked to identify the ink color of the words independent of color that the words named; in the
HotStroop task, the participants were asked to identify the
emotional expressionof a face independent of the emotion named by a simultaneously displayed written word. We found that cool
inhibitory controlabilities develop linearly with age, whereas
hot
inhibitory controlabilities follow a quadratic developmental pattern, with adolescents displaying worse
hot
inhibitory controlabilities than children and adults. In addition, cool and
hot
inhibitory controlabilities were correlated in children but not in adolescents and adults. The present study suggests (a) that cool and
hot
inhibitory controlabilities develop differently from childhood to adulthood – i.e., that cool inhibition follows a linear developmental pattern and
hotinhibition follows an adolescent-specific pattern – and (b) that they become progressively more domain-specific with age.
