Researchers who have previously explored the relation of broad-based temperamental approach constructs, such as surgency/extraversion, exuberance, or behavioral approach sensitivity, to academic competence (AC) in early elementary school have often found conflicting results. Moreover, few researchers have examined the interaction between these approach reactivity constructs and effortful control (EC) in the prediction of AC. The goal of the current study was to examine the fine-tuned relations of different aspects of temperamental approach reactivity in early childhood (42 and 54 months; N=223), such as impulsivity, frustration, and positive affect, as well as EC, to AC during early elementary school (72 and 84 months). Examining the complex relations may clarify the literature using broad-based approach reactivity constructs. Temperament was observed in the laboratory when children were 54 months of age. Mothers and caregivers also reported on children's impulsivity at 42 and 54 months. School-related behavioral adjustment was reported by children, mothers, and teachers, and GPA was reported by teachers at 72 and 84 months. The results of the study indicated that positive affect, EC, and receptive language ability were the only unique direct predictors of school adjustment and/or GPA. Without EC in the model, only positive affect and vocabulary predicted AC. Frustration, positive affect, and impulsivity each interacted with EC to predict AC outcomes, such EC was only related to higher AC for children with high impulsivity or anger, or low positive affect. Additionally, positive affect and impulsivity interacted to predict GPA, such that impulsivity was positively related to GPA for children with high positive affect, but it was negatively, albeit nonsignificantly, associated with GPA for children with low positive affect. These results were found to be similar for boys and girls. Finding are discussed in terms of the developmental importance of early EC for academic competence for children who have high approach reactivity, as well as the interactive effects of dimensions of approach reactivity on academic achievement.

Description
The present study tested 1) whether children’s bedtimes, wake times, and sleep

durations change as they transition into kindergarten (TtoK), 2) if changes to children’s

sleep schedules were contingent on their pre-kindergarten (T1) napping status and if T1

bedtimes were related to fall (T2) and spring (T3) bedtimes and durations, and 3) whether

The present study tested 1) whether children’s bedtimes, wake times, and sleep

durations change as they transition into kindergarten (TtoK), 2) if changes to children’s

sleep schedules were contingent on their pre-kindergarten (T1) napping status and if T1

bedtimes were related to fall (T2) and spring (T3) bedtimes and durations, and 3) whether

T1 sleep, changes to sleep from T1 to T2, and concurrent sleep quality were related to

academic achievement and participation in 51 kindergarteners. It was hypothesized that

1) wake times would be earlier and sleep duration would be shorter during kindergarten

(T2 and T3) than at T1, 2) children who napped at T1 would go to bed later and have

shorter sleep duration than their non-napping peers and T1 bedtimes would be positively

associated with T2 and T3 bedtimes and negatively associated with T2 and T3 durations,

and 3) more optimal sleep (e.g., consolidated, consistent, and high quality) would be

positively related to academic achievement and participation. Parents reported on

children’s bedtimes, wake times, and nap lengths during T1, T2, and T3. During T3

children wore actigraphs for five consecutive school nights and completed the Woodcock

Johnson tests of achievement (WJ-III). Teachers also reported on children’s participation

in the classroom during T3. Results demonstrated that bedtimes and wake times were

earlier at T2 and T3 than T1. Duration was shorter at T2 and T3 than T1. Additionally,

napping was unrelated to bedtimes and durations, but T1 bedtime was positively related

to T2 and T3 bedtimes and negatively related to T2 and T3 durations. Finally, T1 nap

length, change in bedtimes, and Actigraphy duration were negatively related to

participation. Actigraphy onset variability was positively related to participation.
