To successfully navigate their social worlds, children must adapt their behaviors to diverse situations and do so in a fluid fashion. The current study explored preschool-aged children's sensitivity to a gameplay context (cooperative/competitive) and messages from another (fictional) player (team-oriented/self-oriented) while distributing gameplay…

The current study is the first to provide a comprehensive examination of the activation--decision--construction model (Walczyk, Roper, Seemann, & Humphrey, 2003, 2009) in relation to young children's lie-telling and lie maintenance. Young children (3 to 4 years of age, N = 93) completed the temptation-resistance paradigm to elicit a…

According to some accounts, the bilingual advantage is most pronounced in the domain of executive attention rather than inhibition and should therefore be more easily detected in conflict adaptation paradigms than in simple interference paradigms. We tested this idea using two conflict adaptation paradigms, one that elicits a list-wide…

Children frequently select learning sources based on epistemic cues, or cues pertaining to informants' knowledge. Previous research has shown that preschoolers preferentially learn from informants who have been accurate in the past, appear confident, or have had visual access to relevant information. The present series of studies aimed to…

In the present work, we investigate the hypothesis that failures of task-related executive control that occur during episodes of mind wandering are associated with an increase in extraneous movements (fidgeting). In 2 studies, we assessed mind wandering using thought probes while participants performed the metronome response task (MRT), which…

Executive functions (EFs) and intelligence were examined concurrently and longitudinally in 126 preschool children. EF was assessed using the Flexible Item Selection Task (FIST) and the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Children's intelligence was assessed using the Verbal and Performance subtests from…

Lying is a pervasive human behavior. Evidence to date suggests that from the age of 42 months onward, children become increasingly capable of telling lies in various social situations. However, there is limited experimental evidence regarding whether very young children will tell lies spontaneously. The present study investigated the emergence of…

In light of emerging evidence suggesting that the affective quality of parent-child relationships may relate to individual differences in young children's executive functioning (EF) skills, the aim of this study was to investigate the prospective associations between attachment security in toddlerhood and children's EF skills in kindergarten.…

Although dual-task interference is ubiquitous in a variety of task domains, stop-signal studies suggest that response inhibition is not subject to such interference. Nevertheless, no study has directly examined stop-signal performance in a dual-task setting. In two experiments, stop-signal performance was examined in a psychological refractory…
