Adolescents' inhibitory control: keep it cool or lose control

Area of Science:

• Cognitive Development
• Neuroscience
• Developmental Psychology

Background:

• Inhibitory control is crucial for cognitive and socio-emotional development.
• Previous research shows discrepancies in the development of inhibitory control in emotionally charged contexts.
• Understanding the distinct developmental trajectories of cool and hot inhibitory control is essential.

Purpose of the Study:

• To investigate the developmental patterns of cool and hot inhibitory control across childhood, adolescence, and adulthood.
• To determine the degree of specificity between cool and hot inhibitory control at different age groups.
• To clarify discrepancies in previous findings regarding inhibitory control development in affective contexts.

Main Methods:

• Participants (children, adolescents, adults) completed a neutral (Cool Stroop) and an emotional (Hot Stroop) task.
• The Cool Stroop task assessed the ability to identify ink color, ignoring word meaning.
• The Hot Stroop task assessed the ability to identify facial expressions, ignoring written emotional words.

Main Results:

• Cool inhibitory control demonstrated a linear developmental increase with age.
• Hot inhibitory control exhibited a quadratic developmental pattern, with adolescents showing lower performance than children and adults.
• Cool and hot inhibitory control were correlated in children but not in adolescents or adults.

Conclusions:

• Cool and hot inhibitory control follow distinct developmental pathways from childhood to adulthood.
• Hot inhibitory control shows an adolescent-specific developmental pattern.
• The domain specificity of inhibitory control abilities increases with age.
