Description
Recent research on alcohol use among LGB young adults indicates that sexual minority youth are at increased risk relative to their heterosexual peers. One possible contributing factor is that religiosity fails to provide the significant protection for LGB youth that it has been demonstrated to provide in general population samples. Although recent studies provide some support for this hypothesis, there is little research seeking to understand the reasons that religiosity may fail to protect against heavy drinking among LGB youth. The current study attempted to address this gap by examining relations among religiosity, age of self-identification, and alcohol use in a sample of 103 young adults self identified as lesbian, gay, or bisexual. Using multiple regression, we found that religiosity had an indirect effect on alcohol use operating through age of identification as LGB. Higher religiosity was associated with a later age of self-identification, which in turn, predicted greater increases in alcohol use among LGB youth during the transition from high school through college. Exploratory analyses found that gender significantly moderated the influence of age of self-identification on alcohol use such that a later age of self-identification was a risk factor for increased drinking for women, but not for men. The findings have important implications for understanding complex relations between religiosity and alcohol use among LGB youth. In addition, the findings may inform the development of religious support groups for LGB youth that will allow them to experience the benefits of religious involvement that heterosexual youth experience.

Description
This study examined the relation between Religiosity (a motivational system) and Working Memory Capacity (a cognitive system) to determine how they interact to promote goal-directed behavior. Participants completed a religiosity questionnaire and engaged in a battery of tasks that were used to assess their Working Memory Capacity (WMC) and overall ability to maintain goal-directed behavior. The Stroop task was used to examine the participants' ability to maintain goals in the face of interference. It was predicted that religiosity and WMC would be inversely related and that when we controlled for religiosity, WMC would be the only significant predictor of Stroop performance. Furthermore, we hypothesized that religiosity and Stoop would be inversely related, whereas WMC and Stroop would be positively correlated with one another. Religiosity and Stroop performance were each divided into three different components. Religiosity was divided into: Intrinsic Motivation, Extrinsic Motivation, and CARMA. Stroop Performance was measured through Stroop Accuracy, the Stroop Effect, and Post-Error Slowing. The results of our study supported each of our hypotheses. These findings demonstrated that there is a cognitive process underlying motivational systems, such as religion, which affect an individual's ability to sustain goal-directed behavior.

Description
Motor behavior is prone to variable conditions and deviates further in disorders affecting the nervous system. A combination of environmental and neural factors impacts the amount of uncertainty. Although the influence of these factors on estimating endpoint positions have been examined, the role of limb configuration on endpoint variability has been mostly ignored. Characterizing the influence of arm configuration (i.e. intrinsic factors) would allow greater comprehension of sensorimotor integration and assist in interpreting exaggerated movement variability in patients. In this study, subjects were placed in a 3-D virtual reality environment and were asked to move from a starting position to one of three targets in the frontal plane with and without visual feedback of the moving limb. The alternating of visual feedback during trials increased uncertainty between the planning and execution phases. The starting limb configurations, adducted and abducted, were varied in separate blocks. Arm configurations were setup by rotating along the shoulder-hand axis to maintain endpoint position. The investigation hypothesized: 1) patterns of endpoint variability of movements would be dependent upon the starting arm configuration and 2) any differences observed would be more apparent in conditions that withheld visual feedback. The results indicated that there were differences in endpoint variability between arm configurations in both visual conditions, but differences in variability increased when visual feedback was withheld. Overall this suggests that in the presence of visual feedback, planning of movements in 3D space mostly uses coordinates that are arm configuration independent. On the other hand, without visual feedback, planning of movements in 3D space relies substantially on intrinsic coordinates.

Description
This research examined the influence that Christian and Hindu religious beliefs have on environmentalism; specifically, whether beliefs that one would return to this earth after death (i.e., a belief in reincarnation) and how the world might end may explain more positive attitudes toward the environment. Participants were 533 self-identified Christians and Hindus in the United States and India who completed an online survey assessing religiosity, positive attitudes towards environmentalism, afterlife beliefs, and eschatological beliefs. Christians showed significantly lower ratings of environmentalism compared with Hindus. There were also significant negative differences found based on beliefs about heaven, eschatology beliefs, and increased religiosity in Christians, and significant positive differences found based on reincarnation, eschatology beliefs, and increased religiosity in Hindus. Overall, these results suggest that Christians are less likely to have positive attitudes toward environmentalism compared with Hindus, and that beliefs about the afterlife and the end of the world were significant predictors of environmentalist attitudes.

Description
The premise of the embodied cognition hypothesis is that cognitive processes require emotion, sensory, and motor systems in the brain, rather than using arbitrary symbols divorced from sensorimotor systems. The hypothesis explains many of the mechanisms of mental simulation or imagination and how they facilitate comprehension of concepts. Some forms of embodied processing can be measured using electroencephalography (EEG), in a particular waveform known as the mu rhythm (8-13 Hz) in the sensorimotor cortex of the brain. Power in the mu band is suppressed (or de-synchronized) when an individual performs an action, as well as when the individual imagines performing the action, thus mu suppression measures embodied imagination. An important question however is whether the sensorimotor cortex involvement while reading, as measured by mu suppression, is part of the comprehension of what is read or if it is arises after comprehension has taken place. To answer this question, participants first took the Gates-MacGinitie reading comprehension test. Then, mu-suppression was measured while participants read experimental materials. The degree of mu-suppression while reading verbs correlated .45 with their score on the Gates-MacGinitie test. This correlation strongly suggests that the sensorimotor system involvement while reading action sentences is part of the comprehension process rather than being an aftereffect.
