Argues there is reason for more optimism concerning the effects of reading to preschoolers than suggested by the Scarborough and Dobrich review in this issue (PS522390). Discusses methodological problems in many studies; cites studies indicating direct and indirect links between reading to preschoolers and reading achievement, suggesting that…

Comments on Scarborough and Dobrich review in this issue (PS522390), which found that parents' shared book reading with preschoolers accounts for only 8% of the variance on literacy outcome measures. Addresses the following three points: (1) the merits of further attention to shared book reading; (2) improvements in methodology; and (3) the…

Responds to commentaries (PS522392 and PS522391) on the Scarborough and Dobrich review on the efficacy of reading to preschool children in this issue (PS522390). Provides additional details regarding the computation of average effects and the comparison of effect sizes, and offers additional comments about the contribution of home literacy…

Identifies theoretical assumptions underlying the "commonsense view" that social behaviors, such as joint attention, social referencing, and protocommunication acts, which emerge toward the end of the first year of life, have been taken as evidence of considerable social understanding, even an "implicit" theory of mind. Argues against this view…

Describes the nature and consistency differences in mother-infant interaction affected by sex of infant, and reviews past interpretations. Offers an alternative interpretation, drawing on evidence from animal studies, studies of pregnant women, and work by epidemiologists and ethologists on sex ratio data that suggests mothers of male infants may…

Reviews research literature on television's influence on children's fantasy play. Notes evidence that television viewing absorbs time that children would otherwise spend in play and that television's influence on play depends on the types of programs watched. Examines whether television viewing influences fantasy play positively or negatively and…

Argues that individual and group differences in priming performance scores are heavily influenced by overall speed and accuracy, and thus are a flawed reflection of internal activation of semantic priming. Suggests that meaningful comparison of groups on the activation underlying priming difference scores requires removing the effects of overall…

Notes the tumultuous relationship between researchers and theorists who identify with either Jean Piaget or Lev Vygotsky. Argues that both theorists start from basically the same place in developing their contributions to the study of human development and that new and important theoretical contributions may be possible through a dialectical…

Reviews research assessing the mother's contribution to children's early symbolic play competence, focusing on children ages 12-36 months. Finds that, as with other family members, mothers can encourage pretend play, but perhaps there is no special maternal role in the process. The quality and quantity of sophisticated play might be affected by…

Reviews research on influences on children's symbolic play. Finds little support for the effects of child-adult symbolic play interactions on child solitary play. Discusses three theoretical perspectives that should support these effects: attachment, ethological, and scaffolding theories. Reconsiders the essence of specific variables affecting…

Response to article by Bornstein and Tamis-LeMonda in this same issue. Delimits the faults of the ethological, scaffolding, and attachment theories in assessing maternal effects on children's symbolic play. Concludes that environmental influences are important to, but are not necessarily the sole cause of, child behavior. (JW)

Provides a basis from which to critically examine contemporary identity research, by offering a definition of identity, a constructive criticism of the subject approach, and an empirical approach to studying sense of identity. The empirical approach is based on conceptually sound ideas and leads to important questions about identity modes and the…

Explores developmental issues regarding domain theory, a theory explaining moral development. Concludes that this theory does not explain how domains of moral reasoning and behavior evolve, neglects social and historical aspects of domain development, and does not recognize the effects of individual differences on domains. (JW)

Responds to calls for combining the ideas of Piaget and Vygotsky, discussing differences between the two perspectives. Notes that differences are found in underlying assumptions about the nature and process of development, philosophy, stages of development, developmental influences, and the integrity of cognitive structures. Suggests that, given…

Addresses the extent to which differences in Piagetian and Vygotskyan psychologies make their theories incompatible. Differences result from a Vygotskyan belief in a material primary cause for development; Piagetians do not hold this view. Explores this difference in perspective, concluding that, despite it, the two approaches are compatible. (JW)
