First-order and advanced theory of mind (ToM and AToM), and their structures and relations were investigated in 229 children aged 5-8 years. ToM was assessed using 6 tasks from the first-order ToM scale, while AToM was measured using an 18-item battery (higher-order false-belief understanding; strange stories; faux pas test; eyes test;…

Rigorous evaluation of social and emotional learning programs requires the use of measures that provide reliable and valid information on the meaningful differences in children's social emotional skills across treatment and control groups, as well as changes over time. In contexts affected by conflict and crisis, few measures can provide the…

Over half of the children in the U.S. experience adversity early in childhood. These experiences, along with conditions in their families and neighborhoods, have profound developmental effects. The bioecological model of development includes these proximal contexts in a theory of development that incorporates the threats and supports present in…

This article used two studies to investigate sign and symbol mediation in children aged 8-11 years. In role play, children exist at one at the same time in objective reality and their representation of reality. We cannot observe their mental representation directly, but the issue of whether signs or symbols mediate early role play is an important…

Models of personal epistemology have not been sufficiently integrated despite conceptual similarities. We attempted to model both dimensional and positional aspects of personal epistemology, as well as examine the domain specificity of these phenomena. The conceptual framework for this study was a new model of epistemic and ontological cognitive…

Relationships between school achievement and two theoretically different measures of intelligence, Piagetian and psychometric, are explored in 143 bright, average, and retarded elementary school students. Factor analyses of the California Test of Mental Maturity, the Metropolitan Achievement Test, the Stanford-Binet, and fifteen Piaget-type tasks…

The present experiment focused on the development of a "cumulative rehearsal, fast-finish" rehearsal routine. This study was designed for two purposes: (1) to extend the notion of the "executive function" to the case where continued use of mnemonic routine is a reasonable response to an objective change in an information processing task, and (2)…

A CONCEPT ATTAINMENT TASK IN WHICH CHILDREN ARE ASKED TO IDENTIFY A CONCEPT THROUGH DETERMINING WHICH OF A SET OF OBJECTS ARE OR ARE NOT INSTANCES OF IT WAS USED TO INVESTIGATE THEIR PROBLEM-SOLVING BEHAVIOR. OF PARTICULAR INTEREST WAS THE QUESTION OF TO WHAT EXTENT THEY USED OR LEARNED THE STRATEGY OF VARYING ONE FACTOR WHILE HOLDING ALL OTHERS…

The reliance of 12, 18, and 22 children in grades 2, 4, and 6, respectively, on context- versus word-based information was studied. Factor analysis of error scores yielded a structure reflecting 3 information sources: graphophonic information; context to identify words; and comprehension monitoring. Age differences in decoding strategies were…
