This study examined the relationships among visuospatial working memory (WM) executive functioning, and spatial abilities. One hundred sixty-seven participants performed visuospatial short-term memory (STM) and WM span tasks, executive functioning tasks, and a set of paper-and-pencil tests of spatial abilities that load on 3 correlated but distinguishable factors (Spatial Visualization, Spatial Relations, and Perceptual Speed). Confirmatory factor analysis results indicated that, in the visuospatial domain, processing-and-storage WM tasks and storage-oriented STM tasks equally implicate executive functioning and are not clearly distinguishable. These results provide a contrast with existing evidence from the verbal domain and support the proposal that the visuospatial sketchpad may be closely tied to the central executive. Further, structural equation modeling results supported the prediction that, whereas they all implicate some degree of visuospatial storage, the 3 spatial ability factors differ in the degree of executive involvement (highest for Spatial Visualization and lowest for Perceptual Speed). Such results highlight the usefulness of a WM perspective in characterizing the nature of cognitive abilities and, more generally, human intelligence.

The causes of students' academic dishonesty behavior were explored using survey and experimental vignette methods. Participants were surveyed about their own cheating behavior, neutralizing attitudes, performance/mastery orientation and perceptions of peer attitudes and behavior. As predicted, neutralizing attitudes influenced cheating behavior directly, but also indirectly, increasing the effect of individual attitudes. Observing others cheating was strongly correlated with one's own cheating behavior. These variables are also shown to have different effects on exam cheating and plagiarism and cases of giving and receiving unauthorized information. Correlations were tested using experimental vignette methods, which supported the claims made from survey data.
