Normative adult age-related decrements are well documented for many diverse forms of effortful cognitive processing. However, it is currently unclear whether each of these decrements reflects a distinct and independent developmental phenomenon, or, in part, a more global phenomenon. A number of studies have recently been published that show…

Tested 3-, 5-, and 8-year-olds on temporal generalization with visual stimuli. Found increasing sharpness of generalization gradient with increasing age, and change from symmetrical to adult-like asymmetrical generalization gradients among 8-year-olds. Theoretical models attributed changes to increasing precision of the reference memory with…

Examined developmental changes in time estimation among 5- to 99-year olds. Found that older adults and young children performed at lower levels than young adults; identified qualitative differences in error patterns of older adults and children. Proposed model of temporal generalization and bisection assuming developmental changes in noisiness of…

Describes two experiments that examined the effects of quantity and depth of processing on elementary school children's time perception. (HOD)

The model of aging that people construct influences interpretations of and responses to actual situations when they occur, as well as preparatory actions that people take. Thus the question of what people foresee for themselves and the process by which they construct and revise this subjective aging trajectory has implications for such issues as…

Stories were constructed in which minor variations in content influenced the relationship existing between statements. The stories had four episodes, which were either logically related or independent. First and third graders could more accurately recall the structure of the logically organized episodes than that of the temporally listed episodes.…
