Development of hot and cool executive function during the transition to adolescence.

This study examined the development of executive function (EF) in a typically developing sample from middle childhood to adolescence using a range of tasks varying in affective significance. A total of 102 participants between 8 and 15years of age completed the Iowa Gambling Task, the Color Word Stroop, a Delay Discounting task, and a Digit Span task. Age-related improvements were found on all tasks, but improvements on relatively cool tasks (Color Word Stroop and Backward Digit Span) occurred earlier in this age range, whereas improvements on relatively hot tasks (Iowa Gambling Task and Delay Discounting) were more gradual and occurred later. Exploratory factor analysis indicated that performance on all tasks could be accounted for by a single-factor model. Together, these findings indicate that although similar abilities may underlie both hot and cool EF, hot EF develops relatively slowly, which may have implications for the risky behavior often observed during adolescence. Future work should include additional measures to characterize more intensively the development of both hot and cool EF during the transition to adolescence.

Development of affective decision making for self and other: evidence for the integration of first- and third-person perspectives.

The role of perspective taking in affective decision making was studied in children at two ages (3 and 4 years) using a delay-of-gratification paradigm in which children chose between an immediate reward of lower value and a delayed reward of higher value. Half the children chose for themselves (self condition), and half chose for the experimenter (other condition). Three-year-olds chose delayed rewards in the other condition but made impulsive choices in the self condition. Compared with 3-year-olds, 4-year-olds performed better in the self condition and worse in the other condition. Results suggest that 3-year-olds took either a subjective, first-person perspective (for self) or an objective, third-person perspective (for other). Four-year-olds integrated these perspectives, considering a third-person perspective in the self condition and the experimenter's subjective perspective in the other condition (i.e., her desire for immediate gratification). This integration allowed reason to be tempered by emotion, and vice versa.

The development of reasoning about the teaching of values in school and family contexts.

This study investigated children's, adolescents', and young adults' reasoning about the teaching of a variety of values in the school and family contexts. One-hundred and sixty participants in four age groups (8-, 10-, and 13-year-olds, and college students) evaluated acts involving the teaching of values and laws that regulate the teaching of these values. Both the valence (positive or negative) of values and the context in which they were presented (school, family) were systematically varied. Results showed that a variety of factors were considered in evaluating the teaching of values, including context, the valence of the value, and the type of value being taught. Participants' reasoning about values education was found to be multifaceted and included distinctions between moral values that reflect justice and rights, and values that reflect other forms of personality traits and social values. The findings suggest that conceptions of values education may be better understood within models of social reasoning that draw distinctions between types of values (e.g., moral and other values) and account for the increasing capacity to differentiate social contexts and spheres of legitimate governmental regulation with development.
