Assessing social cognition: age-related changes in moral reasoning in childhood and adolescence.

OBJECTIVE

There is increasing recognition that socio-cognitive skills, such as moral reasoning (MR), are affected in a wide range of developmental and neuropsychological conditions. However, the lack of appropriate measures available to neuropsychologists poses a challenge for the direct assessment of these skills. This study sought to explore age-related changes in MR using an innovative visual tool and examine the developmental sensitivity of the task.

METHOD

To address some of the methodological limitations of traditional measures of MR, a novel, visual task, the Socio-Moral Reasoning Aptitude Level (So-Moral), was used to evaluate MR in 216 healthy participants aged 6-20 years.

RESULTS

The findings show a linear increase in MR from childhood to late adolescence with significant group differences between childhood (6-8 years) and preadolescence (9-11 years), and between early adolescence (12-14 years) and middle adolescence (15-17 years).

CONCLUSIONS

Interpreted in light of current brain development research, the results highlight age-related changes in MR that offer insight into typical MR development and opportunities for comparisons with clinical populations. The findings also provide evidence of the potential of the So-Moral as a developmentally appropriate measure of MR throughout childhood and adolescence.
