Causal uncertainty is the degree to which an individual believes they understand why social events occur. When people feel causally uncertain, they become motivated to reduce their uncertainty, and past research has shown that individuals high in causal uncertainty (i.e. frequently feel uncertain about the causality of social events) will engage in more thoughtful and … [Read more…]

Program efficacy was compared to … [Read more…]

Researchers hypothesized conscientiousness … [Read more…]
The cerebellum is a brain region that is associated with proprioception (the ability to sense the position of limbs in space), and has a protracted developmental period. Research suggests that postnatal development of the Purkinje cell (PC) layer in the cerebellum of rodents is dependent on neural activity. PC development is characterized by polyinnervation of … [Read more…]

Specifically, mean R wave amplitude was assessed via 3-lead … [Read more…]
Inadvertent plagiarism, also known as cryptomnesia, involves being presented with another person’s idea and then reproducing it later, believing it to be a new idea. Although this type of plagiarism is unintentional and is usually completely unconscious, it can still have serious consequences. Though inadvertent plagiarism has been studied before, the degree of familiarity between … [Read more…]
Evaluative conditioning occurs when a person changes how he or she views a previously neutral stimulus. Because EC changes how people consider previously neutral stimuli, it takes a central role in helping us understand how different human preferences develop, and it is thus very important to research.

Previous studies demonstrate that body composition (specifically the amount of body fat) influences autonomic function. The autonomic nervous system is divided into two branches: the sympathetic nervous system prepares the body for energetic action (e.g., increases in heart rate and blood pressure) while the parasympathetic nervous system has antagonistic actions promoting relaxation. Overweight individuals tend … [Read more…]

Through classroom observation, this study looked at the various ways that two adolescent boys in a small-town, working-class American high school constructed masculine identity. Specifically, … [Read more…]
Humans base their identity at least partly in the social groups of which they are members. The presence of competition or conflict between groups can lead the “in-group” to feel that protecting its identity requires self-distinguishment through hostile behavior towards the “out-group.” When these in-groups behave aggressively towards out-groups, members must either conform or sacrifice … [Read more…]
Existing research indicates many women experience significant psychological distress when trying on clothing, especially swimwear. This effect appears to be less pronounced in men.
