The present paper attempts to respond to criticisms made by Keating (1988, Developmental Review, 8, 376-384) regarding the present author’s earlier paper which described a recasted model of formal operations (Bymes, 1988, Developmental Review, 8, 66-87). This earlier paper made a distinction between conceptual and procedural knowledge at the level of formal operations, and presented evidence su...

One future direction for cognitive development research involves a closer integration with our knowledge about the developing brain. I present a framework for analyzing and interpreting postnatal functional brain development in human infants. Three specific hypotheses contribute to this framework, within which a variety of phenomena associated with the neural basis of perception and cognition i...

To separate effects of maternal depression on infant cognitive versus language development, 1-year-olds were assessed using the revised Bayley Scales of Infant and Toddler Development (BSID-III). Percentile scores on the Bayley Expressive Communication (EC) subscale were significantly negatively correlated with maternal self-report scores on the Beck Depression Inventory (BDI-II). However, moth...

One of the weak points of the present critics of AI is their lack of an alternative cognitive theory. In the paper the outline of such a theory is sketched, based on (one reading) of Piaget's genetic epistemology. This is used to clarify the ambiguity of the terms 'symbol' and 'representation', thereby making it possible to suggest a reconciliation of the positions of the critics and defenders ...

We present the results of multivariate normal mixture modeling of Piagetian data. The sample consists of 101 children, who carried out a (pseudo-)conservation computer task on four occasions. We fitted both cross-sectional mixture models, and longitudinal models based on a Markovian transition model. Piagetian theory of cognitive development provides a strong basis for the number and interpreta...

The relationship between gay identity development and cognitive development, as outlined by Ivey's Developmental Counseling Therapy Model, was explored. The Gay Identity Questionnaire and the Standard Developmental Counseling Interview were administered to 78 gay men. Results suggested that there is a relationship between gay identity development and cognitive development. In addition, the find...

With this special section on children, adolescents, and the Internet, we survey the state of a new field of inquiry in developmental psychology. This field is important because developmentalists need to understand how children and adolescents live in a new, massive, and complex virtual universe, even as they carry on their lives in the real world. We have selected six empirical articles to show...

Inferring others' preferences is socially important and useful. We investigated whether children infer preferences from the minimal information provided by an agent's single action, and whether they avoid inferring preference when the action is constrained. In three experiments, children saw vignettes in which an agent took a worse toy instead of a better one. Experiment 1 shows that this singl...

Predicting the future, even the near future, of theory and research in cognitive development is a formidable task. To do so in a relatively short chapter allows one to hit the highlights and forgo the all-too-important details, which makes the task a bit less daunting. To help set the stage for this chapter, a brief account of the recent history of the field is provided. Then the discussion tur...
