Two experiments explored the role of vicarious " self " explanations in facilitating student learning gains during computer-presented instruction. In Exp. 1, college students with low or high knowledge on Newton's laws were tested in four conditions: (a) monologue (M), (b) questions (Q), (c) explanation (E), and (d) question þ explanation (Q þ E).

The extent to which personality disorders (PDs) and associated symptom criteria were found among 117 cocaine- and opioid-dependent men selected from 350 consecutive inpatient admissions to a Veterans Administration Drug Dependence Treatment Unit over a 30-month period was examined using structured interview methodology. Drug groups were distinguished by(More)
The current study investigated the role of discourse scaffolds embedded into vicarious learning environments in classroom learning. In the current study, one of three vicarious learning conditions with varying levels of discourse scaffolds preceded standard instruction on seven classroom days. An explanation condition included deep questions, course content(More)
Hazardous drinking among US Military combat veterans is an important public health issue. Because recent combat veterans are difficult to engage in specialty mental health and substance abuse care, there is a need for opportunistic interventions administered in settings visited by recent combat veterans such as primary care. This paper describes a brief(More)
OBJECTIVE The purpose of this study was to test the efficacy of 2 brief interventions for alcohol misuse in a sample of combat veterans of the wars in Iraq and Afghanistan. METHOD Participants were 68 combat veterans (91.2% male; 64.7% White, 27.9% Black) with a mean age of 32.31 years (SD = 8.84) who screened positive for hazardous drinking in a Veterans(More)
Although DSM-IV-TR diagnostic criteria for posttraumatic stress disorder (PTSD) include three primary symptom clusters, recent evidence from confirmatory factor analyses suggest that the latent structure of PTSD is better represented by four factors, which will likely be reflected in the upcoming DSM-5. Given this likely transition from three to four(More)
Elevated alcohol reward value (RV) has been linked to higher levels of drinking and alcohol-related consequences, and there is evidence that specific drinking motives may mediate the relationship between demand and problematic alcohol use in college students, making these variables potentially important indicators of risk for high RV and alcohol problems.(More)
Violent loss survivors often describe experiencing recurrent imagery about their loved one's death. The Death Imagery Scale assesses 5 kinds of imagery: reenactment, rescue, revenge, reunion, and remorse. We explored the frequency of these forms of imagery and their associations with PTSD, depression, and/or complicated grief (CG) among 130(More)
Combat traumas precipitate PTSD, however non-traumatic deployment and post-deployment factors may also contribute to PTSD severity. The Deployment Risk and Resilience Inventory was used to investigate pre, peri and post-deployment factors associated with current PTSD severity in 150 recent combat veterans with PTSD and hazardous alcohol use.
