Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

This 5-year longitudinal study examined whether high mathematics achievers in primary school had cognitive advantages before entering formal education. High mathematics achievement was defined as performing above Pc 90 in Grades 1 and 3. The predominantly White sample (M[subscript age] in preschool: 64 months) included 31 high achievers (12 girls)…

Cognitive effort is costly and this cost likely influences the activities in which children engage. Yet, little is known about how school-age children perceive cognitive effort. The subjective value of cognitive effort, that is, how valuable or costly effort is perceived, was investigated in seventy-three 7- to 12-year-olds using an effort…

Results of three experiments support the conclusion that tasks involving the localization of objects or events from mirror images are not direct indices of self-recognition among children between 14 and 22 months of age. Rather, they indicate the skill of infants in using the mirror as a perceptual tool. (RH)

Results of four studies confirmed the hypothesis that three year olds would have less difficulty inferring that another person holds an odd belief about a matter of taste or value than they have in inferring that another person holds a false belief about a matter of verifiable fact. (RH)

Undertaken within the framework of the best example theory of categorization, this study investigates category acquisition as a function of initial exposure to only good exemplars and as a function of exposure to single as opposed to multiple exemplars. Six severely handicapped children, ranging in age from 8 to 18 years, participated. (Author/MP)

In three experiments, children of three through six years of age were generally better able to reproduce a perceiver's perspective if a visual cue in the perceiver's line of sight was salient. Children had greater difficulty when the task hinged on attending to configural cues. Availability of distinctive cues affixed to objects facilitated…

This study of 114 children between seven and nine years used a procedure for directly observing child-produced and experimenter-produced strategies to examine the transitional period of strategy development. Findings revealed gradual changes in children's ability to produce, and to benefit from, a strategy of selective attention. (RH)

Four studies determined when first, second, and third graders recognize that they make inferences to understand text, and the effect of this recognition on their ability to revise text and monitor its informativeness. Younger children tended to attribute inferred information to the text, while older children clearly distinguished inferred and…

In comparison with full-term infants, seven-month-old high-risk preterm infants exhibited deficits in visual recognition memory and in the ability to recruit, sustain, and shift attention. (RH)

Tested whether intrinsic motivation depends on matching cognitive level and task demands and assessed effects of rewards and praise on intrinsic motivation. Children preferred tasks just beyond their ability levels. Praise had mixed effects: rewards decreased intrinsic motivation among highly motivated children but did not influence intrinsic…

Three studies investigated preschoolers' reasoning about ability. Findings suggested sensitivity to mental state information when judging another child's ability, and they perceived positive correlations between effort and academic success, and "niceness" and high academic ability. Comparisons with 9- to 10-year-olds suggest that…
