Autochthonous determinants of perception are accurately measured by psychophysics. There is need for equally precise measurement of motivational determinants. The experiments on estimating size were planned to test hypotheses that such determinants are more influential when objects have greater social or individual value. Ten-year-old children adjusted a lighted circle to the perceived size of 5 coins and 5 cardboard discs. With the objects present, discs ...
Parental death is 1 of the most traumatic events that can occur in childhood, and several reviews of the literature have found that the death of a parent places children at risk for a number of negative outcomes. This article describes the knowledge base regarding both empirically supported, malleable factors that have been shown to contribute to or protect children from mental health problems following ...
Within each of 18 classrooms, an average of 20% of the children were reported to classroom teachers as showing unusual potential for intellectual gains. Eight months later these “unusual” children (who had actually been selected at random) showed significantly greater gains in IQ than did the remaining children in the control group. These effects of teachers' expectancies operated primarily among the younger children. Rosenthal, R., & ...
This article reviews the evidence and theory pertaining to a form of perspective-taking failure—a difficulty in setting aside the privileged information that one knows to be unavailable to another party. The authors argue that this bias (epistemic egocentrism, or EE) is a general feature of human cognition and has been tapped by 2 independent and largely uncommunicating research traditions: the theory-of-mind tradition in developmental psychology ...
Eighty-eight young 3-, 4-, and 5-year-olds were scheduled for 2 testing sessions. On Visit 1, the children were videotaped playing a game while an experimenter covertly placed a large sticker on their head and covertly removed it after the game. One week later, the children were videotaped playing a different game. A sticker was again covertly placed on their heads. Half the children in each ...
