Age and experience effects on the interpretation of orthographic drawings of three-dimensional objects.

Abstract

Adults of different ages and experience levels attempted to recognize wire-frame drawings of 3-dimensional objects originally displayed in orthographic views. Although only slight age relations were evident on a measure of decision accuracy in the criterion task, increased age was associated with poorer performance on several tasks hypothesized to assess component processes. Furthermore, there was no significant alteration in any of the performance measures by statistically controlling for amount of relevant experience, and there was no evidence that people of different ages, or different levels of experience, relied on different abilities to perform the criterion task. These results seem to imply that experience neither mediates nor moderates age-related influences on certain measures of relatively basic cognitive processes.
