Acculturative stress, social support, and coping: relations to psychological adjustment among Mexican American college students

This study examined the relations between acculturative stress and psychological functioning, as well as the protective role of social support and coping style, in a sample of 148 Mexican American college students (67% female, 33% male; mean age = 23.05 years, SD = 3.33). In bivariate analyses, acculturative stress was associated with higher levels of anxiety and depressive symptoms. Moreover, active coping was associated with better adjustment (lower depression), whereas avoidant coping predicted poorer adjustment (higher levels of depression and anxiety). Tests of interaction effects indicated that parental support and active coping buffered the effects of high acculturative stress on anxiety symptoms and depressive symptoms. In addition, peer support moderated the relation between acculturative stress and anxiety symptoms. Implications for reducing the effects of acculturative stress among Mexican American college students are discussed.     

The relationship between personality and discretionary helping behaviors

The relationship between personality and helping behaviors in three different contexts was examined in a field study. In a sample of 178 employees from three professional organizations, measures of the Big Five Personality factors were found to be related to discretionary helping behaviors performed in the context of one's home, workplace and the larger society. Collectively, the five personality factors accounted for 7% of the variance in Household Activities and Chores, 26% of the variance in Organizational Citizenship Behaviors and 10% of the variance in Volunteerism. Implications of these relations are discussed.     

Do Birds of a Feather Cheat Together? How Personality and Relationships Affect Student Cheating

Academic misconduct is widespread in schools, colleges, and universities and it appears to be an international phenomenon that also spills over into the workplace (Nonis and Swift 2001; Sims 1993; Stone et al. 2011). To this end, while a great deal of research has investigated various individual components such as, demographic, personality and situational factors that contribute to cheating, research has yet to examine why students help others cheat and which students are being asked to help others cheat. In this study, we investigated if the closeness of the relationship to the individual requesting help in cheating to the individual being asked to help cheat, influenced the decision to help cheat. We also investigated if past cheating behavior predicted how an individual would respond to requests to cheat. Additionally, we sought to answer the following questions; whether minor cheating is more prevalent than serious cheating, what personality factors predict helping others cheat, who is helped, and how people rationalize helping others cheat. Results indicate minor cheating to be more prevalent, prudent personalities are less likely to have cheated or to help others cheat, individuals are more likely to help friends cheat than to help strangers, and past cheating behaviors is indicative of helping others to cheat. Implications for research and practice are discussed.     

Parent-peer influence as a predictor of marijuana use.

Although there is some literature which discusses adolescent reference groups, none have utilized reference group theory to examine the relative impact of the parent and peer reference groups and to attempt to predict behavior among teenagers from this knowledge. This study attempts to correct this deficiency by examining the frequency of marijuana use in a nonrandom sample of college students from a large southwestern university. Ordinal type scales and tau-b provide a statistically strong degree of association between the type of reference group orientation and marijuana use. The results of this study show that the influence of the most salient reference group appears to be an important predictor of whether or not an individual may engage in the use of marijuana.     

Perception and recognition memory of words and werds: Two-way mirror effects

We examined associative priming of words (e.g., TOAD) and pseudohomophones of those words (e.g., TODE) in lexical decision. In addition to word frequency effects, reliable base-word frequency effects were observed for pseudohomophones: Those based on high-frequency words elicited faster and more accurate correct rejections. Associative priming had disparate effects on high- and low-frequency items. Whereas priming improved performance to high-frequency pseudohomophones, it impaired performance to low-frequency pseudohomophones. The results suggested a resonance process, wherein phonologic identity and semantic priming combine to undermine the veridical perception of infrequent items. We tested this hypothesis in another experiment by administering a surprise recognition memory test after lexical decision. When asked to identify words that were spelled correctly during lexical decision, the participants often misremembered pseudohomophones as correctly spelled items. Patterns of false memory, however, were jointly affected by base-word frequencies and their original responses during lexical decision. Taken together, the results are consistent with resonance accounts of word recognition, wherein bottom-up and top-down information sources coalesce into correct, and sometimes illusory, perception. The results are also consistent with a recent lexical decision model, REM-LD, that emphasizes memory retrieval and top-down matching processes in lexical decision.     

Visual recognition of biological motion is impaired in children with autism

Autistic children and typically developing control children were tested on two visual tasks, one involving grouping of small line elements into a global figure and the other involving perception of human activity portrayed in point-light animations. Performance of the two groups was equivalent on the figure task, but autistic children were significantly impaired on the biological motion task. This latter deficit may be related to the impaired social skills characteristic of autism, and we speculate that this deficit may implicate abnormalities in brain areas mediating perception of human movement.
