    A cross-sectional examination of response inhibition and working memory on the Stroop task
    (Cognitive Development, 2018-07-01) Duell, N; Icenogle, G; Silva, K; Chein, J; Steinberg, L; Banich, MT; Di Guinta, L; Dodge, KA; Fanti, KA; Lansford, JE; Oburu, P; Pastorelli, C; Skinner, AT; Sorbring, E; Tapanya, S; Uribe Tirado, LM; Alampay, LP; Al-Hassan, SM; Takash, HMS; Bacchini, D; Chang, L; Chaudhary, N
    © 2018 Elsevier Inc. The authors examined the association between working memory and response inhibition on the Stroop task using a cross-sectional, international sample of 5099 individuals (49.3% male) ages 10–30 (M = 17.04 years; SD = 5.9). Response inhibition was measured using a Stroop task that included “equal” and “unequal” blocks, during which the relative frequency of neutral and incongruent trials was manipulated. Competing stimuli in incongruent trials evinced inhibitory functioning, and having a lower proportion of incongruent trials (as in unequal blocks) placed higher demands on working memory. Results for accuracy indicated that age and working memory were independently associated with response inhibition. Age differences in response inhibition followed a curvilinear trajectory, with performance improving into early adulthood. Response inhibition was greatest among individuals with high working memory. For response time, age uniquely predicted response inhibition in unequal blocks. In equal blocks, age differences in response inhibition varied as a function of working memory, with age differences being least pronounced among individuals with high working memory. The implications of considering the association between response inhibition and working memory in the context of development are discussed.

    Subtypes of childhood social withdrawal and adult relationship and parenting outcomes
    (International Journal of Behavioral Development, 2024-01-01) Reilly, EB; Dodge, KA; Bai, Y; Lansford, JE; Bates, JE; Pettit, GS
    The aims of the current 30 year prospective study were to determine: (1) whether socially withdrawn kindergarten children are less likely than others to enter serious romantic relationships or become parents by age 34, (2) whether socially withdrawn children parent differently than non-withdrawn individuals when they grow up, and (3) whether subtypes of withdrawal are associated with different adult outcomes. Following Harrist et al. (1997), 558 kindergarten children (81% White, 17% Black) were categorized into one of the five groups: four clusters of social withdrawal (n = 95 unsociable, 23 passive-anxious, 18 active-isolate, and 25 sad/depressed) or non-withdrawal (n = 397), using directly observed school behavior and teacher ratings. About 30 years later (Mage = 34.45 years, SD = 0.62 years), participants self-reported on their romantic relationship and parent status and parenting warmth and harshness. Overall, the group of socially withdrawn children was no more or less likely than the non-withdrawn group to be in a current relationship or a parent, nor did they report any differences in parenting. However, the active-isolate subtype of social withdrawal, characterized by impulsivity and anger, was less likely than the non-withdrawn group to be in a current relationship (B = −1.24, p < 0.05). This study suggests socially withdrawn children in the United States fare similarly to non-withdrawn peers in adulthood in their romantic relationships and parenting, but a subgroup of active-isolate children may be at risk of not entering adult relationships.
