Critical Thinking in Ethical and Neutral Settings in Gifted Children and Non-Gifted Children

The present study examined the performance on five phases of critical thinking in gifted and nongifted children in two settings: ethical and neutral. Ninety-one children, 32 gifted (8-10 years old), 32 normally developing children matched for chronological age (8-10 years old) and 27 normally developing children matched for mental age (12-13 years old) completed critical thinking tasks. The findings confirmed that intellectually gifted children had higher critical thinking capacity than typically developing children. The results reveal that the basic factor determining best performances in critical thinking is mental age and not chronological age. However, critical thinking ability was the same in ethical and neutral settings. Analysis of the phases of critical thinking show that the first and the third phase, clarification and evaluation, specifically differentiates gifted from nongifted children. These phases refer to the ability to understand the type of problem rapidly and to assess the credibility of statements and to assess the logical strength of the actual or intended inferential relationships among statements, descriptions, questions or other forms of representation.

How children revise their beliefs in light of reasons

We investigate how the ability to respond appropriately to reasons provided in discourse develops in young children. In Study 1 (N = 58, Germany, 26 girls), 4- and 5-, but not 3-year-old children, differentiated good from bad reasons. In Study 2 (N = 131, Germany, 64 girls), 4- and 5-year-old children considered both the strength of evidence for their initial belief and the quality of socially provided reasons for an alternative view when deciding whether to change their minds. Study 3 (N = 80, the United States, 42 girls, preregistered) shows that 4- and 5-year-old children also consider meta-reasons (reasons about reasons) in their belief revision. These results suggest that by age 4, children possess key critical thinking capacities for participating in public discourse.

Infants actively seek and transmit knowledge via communication

Supporting the central claim that knowledge representation is more basic than belief representation, we focus on the emerging evidence for preverbal infants' active and selective communication based on their representation of both knowledge and ignorance. We highlight infants' ontogenetically early deliberate information seeking and information transmission in the context of active social learning, arguing that these capacities are unique to humans.
