Twenty-two preschoolers aged 48-63 months were observed and questioned by a familiar experimenter about their spontaneous helping, sharing, or comforting behavior over a 12-week period. (JMB)

Assessed teachers' ratings of social behavior and peers' ratings of likability for 43 preschoolers over a 10-month period. Among preschoolers, those who were friendlier, more cooperative, less aggressive, and less difficult were more well liked. Later likability was predicted by earlier likability, not by prosocial behavior. (BC)

Examined understanding of print concepts in preschool children bilingual in English and Hebrew. Found that bilingual children were more advanced than monolinguals, regardless of task (understanding that a printed word's meaning did not change if moved to a new location, making judgments about word length and ignoring the object's size) or whether…

Two studies examined preschoolers' appreciation of how mental states arise. Findings suggest that 3- and 5-year-olds better understood perception-generated beliefs and attitude-generated desires than physiology-generated desires. Four- and 5-year-olds better understood the effects of quantity of experience than of time of experience on…

Examined the developmental courses of temperamental constructs using structural equation model fitting with children from 3 to 48 months of age. Found that across all measurement occasions, models that fit best were those that allowed for stability in temperament to be at least partially mediated through intermediate forms of the trait. (JPB)

The relationships between mothers' and children's speech were analyzed with regard to complexity and usage of selected speech types. The findings suggest that the responsiveness of child speech to mothers' speech seems to influence the mothers' language complexity, allowing the child to exert an influence on his language environment. (JMB)

Four studies examined the cognitive bases of children's judgments of morality. Over 240 children from preschool to fourth grade were participants. Moral dilemmas consisting of information about a character's motives and the consequences of his actions were devised in such a way that the order, concreteness and imageability of information were…

Four-year-olds were reliably accurate about movement potentials for the categories of mammals, nonmammalian animals, statues of animals, wheeled vehicles, and multipart, rigid objects. The three-year-olds' scores were significantly above chance in all categories but animals. Analyses showed that children were concerned about the cause of movement…

Examines children's memory for preschool routines as a function of current grade level and successive modifications in the school-day script. First, children in preschool through third grade were tested, then children in kindergarten through third grade. Results showed a process of generalization for preschool scripts over time. (Author/BB)

Effects of instruction and reward contingency on conformity to a prohibition were studied in preschoolers. Instructions were varied in terms of explicitness and reward was either contingent or not contingent upon following the instructions. (Author/SS)

Results of three studies suggested that children's play was mediated by their age, playmates' sex, and play props. Children's behavior seemed to change with age and with the children's consideration of the sex-role appropriateness of interacting in particular play areas and with particular peers. (RH)

Four-year-olds' and adults' inferences based on shared conceptual properties, category labels, and perceptual information were assessed in four experiments. Stimuli included novel and familiar animals. Found that children made attribute-based inductions as well as category-based inductions, and that perceptual similarity consistently influenced…

Examined the long-term retention of 216 preschoolers, half of whom received a single slide presentation and while the other half received consecutive presentations until they learned the material to criterion. Exposure to misleading information 3 weeks after the presentation encouraged the preschoolers to report misinformation 4 weeks after the…

Three studies examined preschoolers' use of desires to solve theory of mind problems. Findings indicated that even young children could correctly attribute a false belief to an agent when that belief was about the status of a pretense. Subjects found it easier to attribute a false belief when the desires of the agent were eliminated. (Author/KB)
