The spelling of many words in English and in other orthographies involves patterns determined by morphology (e.g., ed in past regular verbs). The authors report a longitudinal study that shows that when children first adopt such spelling patterns, they do so with little regard for their morphological basis. They generalize the patterns to grammatically inappropriate words (e.g., sofed for soft)...

In this article, we try to analyze the requirements of developmental processes from the perspective of their implementation in digital hardware. After recalling the motivations for such an implementation, we concentrate separately on the two mechanisms (cellular division and cellular differentiation) that are exploited by biological systems to realize development. We then describe some of the c...

The purpose of the three studies reported here was to formulate a framework for understanding the development of scientific reasoning processes. Subjects were placed in a simulated scientific discovery context by first teaching them how to use an electronic device and then asking them to discover how a hitherto unencountered function worked. To do this task, subjects had to formulate hypotheses...

Birren and Bengtson’s (1988, p. ix) assessment of the field of aging research that it is “data rich and theory poor” still holds today and applies to developmental science as a whole. The accumulation of descriptive results that are not integrated into overarching theories of development lead to less progress in gaining knowledge about developmental processes than one might wish for, particular...
