This study addressed health disparities in sleep duration, sleep quality, and daytime sleepiness among African-American college students. To investigate evening behaviors promoting insufficient and inadequate sleep, we assessed electronic (e.g., computer and music) and nonelectronic (e.g., socializing) sleep competing activities (SCA). Students (N = 154) were recruited from a Historically Black College (HBCU). The results showed more dysfunction than has previously been reported in college populations, with HBCU students reporting very short sleep durations, high levels of daytime sleepiness, and poor sleep quality. These students engaged in many activities during the evening, and these activities predicted unhealthy sleep. Whereas electronic …

Nativists have postulated fundamental geometric knowledge that predates linguistic and symbolic thought. Central to these claims is the proposal for an isolated cognitive system dedicated to processing geometric information. Testing such hypotheses presents challenges due to difficulties in eliminating the combination of geometric and non-geometric information through language. We present evidence using a modified matching interference paradigm that an incongruent shape word interferes with identifying a two-dimensional geometric shape, but an incongruent two-dimensional geometric shape does not interfere with identifying a shape word. This asymmetry in interference effects between two-dimensional geometric shapes and their corresponding shape words suggests that shape …
