Phillips, Wellman, and Spelke (2002) provided experimental evidence indicating that by the age of 12 months infants use information about an adult's gaze-direction and emotional expression to predict action. We investigate the generality of this ability, using Phillips et al.'s paradigm across different referential gestures. If infants have a rich…

In order to understand ongoing activity, observers segment it into meaningful temporal parts.

Segmentation may also be affected by top-down effects of knowledge structures, including information about actors' intentions. Three…

Shaffer and Hall (1997) have estimated college student gambling to be three times as high as their adult counterparts. Despite a considerable amount of research on gambling, researchers have struggled to develop a universal theory that explains gambling behavior. This study explored the potential of Ajzen and Fishbein's (1980) Theory of Reasoned…

Although a number of investigators have adopted the O'Carroll et al. (1996) nomenclature and applied it in their studies, and others have acknowledged its role in highlighting the need for clarification of terms, the nomenclature has not been widely used in the research and clinical communities. The rationale behind the rebuilding of the O'Carroll…

The present study investigated event-based prospective memory in five age groups of preschoolers (i.e., 2-, 3-, 4-, 5-, and 6-year-olds). Applying a laboratory-controlled prospective memory procedure, the data showed that event-based prospective memory performance improves across the preschool years, at least between 3 and 6 years of age. However,…
