Bjorklund synthesizes promising research directions in developmental psychology using an evolutionary framework. In general terms, we agree with Bjorklund: Evolutionary theory has the potential to serve as a metatheory for developmental psychology. However, as currently used in psychology, evolutionary theory is far from reaching this potential.…

This rejoinder to McCall (Volume 56, 217-218) discusses the differences in viewpoint with respect to the relationship between models and theory, the notion of "direct" tests of propositions, and the use of measures of explained variance to evaluate model performance. (Author/BE)

Argues that in research on the effects of modeling, models must be analyzed as a random factor in order to avoid a positive bias in the results. The concept of a random factor is discussed, worked examples are provided, and a practical solution to the problem is proposed. (JMB)

A model is proposed in which stereotypes are assumed to function as schemas that serve to organize and structure information. The thesis is advanced that sex stereotyping is a normal cognitive process and is best examined in terms of information-processing constructs. (Author/RH)

Reviews Greenough, Black, and Wallace's (1987) conceptual framework for understanding the effects of early experience and sensitive periods on development, and illustrates the applicability of their model with recent data on the consequences for animals and human infants of the acquistion of self-produced locomotion. (BN)

Challenges the typical treatment of causal effects in longitudinal data, arguing that models should be conceptualized and tested in ways that directly reflect prior assumptions as to the trait- or state-like nature of the variables. Examples demonstrate that meaningful longitudinal studies of state variables can be conducted without assuming their…

Argues that developmental psychologists need attitudes, methods, and conceptual schemes that integrate the distinctive contributions of both nature and nurture in order to study change and consistency in developmental functions, as well as individual differences in behaviors of interest. A conceptual scheme for early mental development is…

Presents meta-analysis evidence of the association between paternal sensitivity and infant-father attachment from eight studies with 546 families (combined effect size r = 0.13). A meta-analysis of 950 families from 14 studies found an overall correlation of 0.17 between infant-mother and infant-father attachment. Presents a data-based model of…

Argues that dynamic systems approaches may provide an explanatory framework based on general scientific principles for developmental psychology, using principles of self-organization to explain how novel forms emerge without predetermination and become increasingly complex with development. Contends that self-organization provides a single…

Argues that researchers can achieve objectives of advancing basic knowledge and addressing applied problems within a single research program. Provides a framework for this perspective by examining historical trends of basic and applied developmental research and examining potential approaches. Uses research on affordances and childhood injuries to…

Notes that the Piagetian perspective admits the existence of interindividual differences but interprets them as noise masking the universal logical succession of structures, whereas the differential perspective views development as consisting of "vicarious processes." Asserts that the main aim of the "procedural studies"…

Temperament and attachment, as defined by Bowlby and his followers, are fundamentally different constructs, and research guided by the attachment perspective cannot meaningfully be assimilated to the temperament construct. Qualitative aspects of relationships simply cannot be reduced to individual behavioral dimensions. (RH)

Describes the slot-filler model of taxonomic knowledge development in which preschoolers derive "slot-filler" categories from event schemas. Maintains that the model has received considerable support across methodologies, ages, and sociocultural contexts. Argues that Krackow and Gordon's theorizing and methods could not lead to reliable,…

Focuses on the conceptual implications of analyses of individual differences in francophone post-Piagetian research. Maintains that these analyses are preoccupied by the "American question" of measurement and method, instead of attempting a theoretical account of the issues raised by intraindividual and interindividual variability in…

Describes evolutionary developmental psychology as the study of the genetic and ecological mechanisms that govern the development of social and cognitive competencies common to all human beings and the epigenetic (gene-environment interactions) processes that adapt these competencies to local conditions. Outlines basic assumptions and domains of…
