College Student Samples Are Not Always Equivalent: The Magnitude of Personality Differences Across Colleges and Universities

This research examined the magnitude of personality differences across different colleges and universities to understand (a) how much students at different colleges vary from one another and (b) whether there are site‐level variables that can explain observed differences. Nearly 8,600 students at 30 colleges and universities completed a Big Five personality trait measure. Site‐level information was obtained from the Integrated Postsecondary Education System database (U.S. Department of Education). Multilevel models revealed that each of the Big Five traits showed significant between‐site variability, even after accounting for individual‐level demographic differences. Some site‐level variables (e.g., enrollment size, requiring letters of recommendation) explained between‐site differences in traits, but many tests were not statistically significant. Student samples at different universities differed in terms of average levels of Big Five personality domains. This raises the possibility that personality differences may explain differences in research results obtained when studying students at different colleges and universities. Furthermore, results suggest that research that compares findings for only a few sites (e.g., much cross‐cultural research) runs the risk of overgeneralizing differences between specific samples to broader group differences. These results underscore the value of multisite collaborative research efforts to enhance psychological research.     

The association between religion and self-reported academic honesty among college students

Current research yields inconsistent findings about the association between religious variables and academic cheating among college students. In this study, we investigated possible reasons for this disagreement by examining whether, and to what extent, three particular religious variables: religious identity, affirmation of importance and religious services attendance, are associated with academic honesty among college students. Specifically, we utilised a sample of 2503 American college-aged students from Gallup^® daily tracking survey and used analysis of variance (ANOVA) to address the proposed research question. Research findings indicate that religious service attendance is positively associated with academic honesty among college students. Specifically, students who attend religious services more frequently are less likely to be engaged in academic misconduct than students who attend less frequently. This finding remains consistent when other important factors such as student attitudes toward cheating and gender were included in the analysis.     

Revisiting Mahoney’s ‘My body is a temple…’ study: spirituality as a mediator of the religion–health interaction among adolescents

This study proposes and tests a new model that seeks to explain associations between religion, spirituality and health outcomes among adolescents. Specifically, we test for mediating effects of perceived spirituality on religion–health relations. Using data from the 4-H Study of Positive Youth Development, we find that perceived spirituality mediates religion–health relations, but that varies based on youths’ conceptualisation of spirituality. With findings confirming that perceived spirituality potentially promote youths’ psychosocial health, we offer some future research directions and implications regarding relations between youths’ spirituality, religion and health behaviours.     

Broadening the Study of the Self: Integrating the Study of Personal Identity and Cultural Identity

This article reviews what is known and what remains to be studied, regarding the association between personal identity and cultural identity. Although these two conceptions of identity have inspired separate literatures and have developed independently of one another, globalization and mass immigration have increased the need to study these two conceptions of identity together. The article puts forth recommendations for integrating the literatures on personal identity and cultural identity. These recommendations include using multidimensional constructs to represent both personal identity and cultural identity, refining the measurement of personal identity and of cultural identity, and of studying these conceptions of identity across various ethnic, cultural, and national groups.     

Longitudinal prediction of child outcomes from differing measures of parenting in a low-income sample

This study examined predictions from preschool parenting measures to middle childhood cognitive and socioemotional child outcomes to explore whether parenting assessment methodologies that require more time, training, and expense yield better predictions of child outcomes than less intensive methodologies. Mother-child dyads (N = 278) in low-income African American families were assessed when the child was in preschool, using maternal report, the Home Observation for Measurement of the Environment-Short Form (P. Baker & F. Mott, 1989; R. Bradley & B. Caldwell, 1984), and structured observational measures of parenting. Child outcomes reported by children, mothers, teachers, and direct assessment were collected 4 years later. All parenting methodologies showed some predictive value; however, observational parenting measures showed the strongest and most consistent predictions of child outcomes.     

Heart rate and respiration in reptiles: contrasts between a sit-and-wait predator and an intensive forager

The current study investigated respiration and heart rate in two species of reptiles with distinct behavioral strategies: (1) the Sudan plated lizard (Gerrhosaurus major), a sit-and-wait predator; and (2) the Savanna monitor (Varanus exanthematicus), an intensive forager. It was hypothesized that (a) the plated lizard would not express respiratory sinus arrhythmia, and (b) the monitor, a reptile with behavioral and physiological characteristics similar to mammals, might express respiratory sinus arrhythmia, a pattern previously observed only in mammals. The data demonstrated that although there were strong vagal influences on the heart, respiratory activity was not manifested in the heart rate pattern of the plated lizards. In contrast, the monitor exhibited a reliable ventilatory influence on the heart rate pattern, although the pattern differed from the respiratory sinus arrhythmia observed in mammals. Consistent with the Polyvagal Theory (), the vagal control of the reptilian heart in both species appears to be mediated through the phylogenetically older unmyelinated system, a system that evolved to support metabolic conservation and not social behavior.     

Religious Involvement and Dynamics of Marijuana Use: Initiation,Persistence, and Desistence

Studies that examine the effects of adolescent religiosity on the initiation of, persistence in, and desistence from delinquency are rare. Yet, religion may differentially affect dimensions of delinquency in the early life course. Therefore, using data from the National Longitudinal Study of Adolescent Health (Add Health), we examine the relationship between measures of adolescent religion, as well as changes in religious involvement, and later patterns of marijuana use. We also examine the extent to which religious effects, if any, are mediated by key predictors of delinquency drawn from prominent criminological theories. The results suggest that the primary effect of religion on marijuana use is to prevent its initiation in the first place. Only part of religion's preventative effect on initiation is mediated by social bonds, delinquent peers, or self control. Although religious youth are less likely to ever use marijuana, adolescent religious involvement does not significantly predict desistence from marijuana use.     

The Effect of User Control on the Cognitive and Emotional Processing of Pictures

This paper explores psychology related to the moment that control is exercised during interactions with media. What is the difference in the thoughtful and emotional engagement of viewers with the content presented between reacting to media versus controlling its onset? Subjects viewed pictures on a computer as part of a 2 (control) × 2 (picture type) × 16 (repetitions) × 2 (order) within-subjects experiment (N = 22). In one condition, subjects controlled the picture onset with a computer mouse. In the other condition, the computer controlled the picture onset. Heart rate and skin conductance were collected as indicators of the automatic attention and arousal elicited by each manipulation of control. Results showed that subjects exhibited a cardiac orienting response when the computer controlled the onset of emotional pictures. Subjects failed to orient when they had control over picture onset. Physiological arousal, as measured by skin conductance, was higher when subjects had control over picture onset. Subjects gave higher subjective ratings on valence and arousal for pictures that were presented by the computer. These results are discussed in relation to current assumptions about interactive media and audience activity.     

Music and Language Skills of Children with Williams Syndrome

We examined music and language abilities in a group of children with Williams syndrome (WS, n = 19) and a comparison group of normal children (n = 19) equivalent for receptive vocabulary. Consistent with previous reports and the model of Nonverbal Learning Disabilities (Rourke, 1989), the children with WS scored better on verbal than performance measures of the WISC-III, and performance on simpler verbal tasks (e.g., receptive vocabulary) was superior to performance on more complex verbal tasks (e.g., comprehension). Performance on music tests was relatively good, being comparable to mental age based on receptive vocabulary and similar to that of the comparison group. Music and language abilities were moderately correlated for both groups of children. Compared to normal children, the WS group expressed greater liking of music and a greater range of emotional responses to music.     

Meaning in Life in Emerging Adulthood: A Person‐Oriented Approach

The present study investigated naturally occurring profiles based on two dimensions of meaning in life: Presence of Meaning and Search for Meaning. Cluster analysis was used to examine meaning‐in‐life profiles, and subsequent analyses identified different patterns in psychosocial functioning for each profile. A sample of 8,492 American emerging adults (72.5% women) from 30 colleges and universities completed measures on meaning in life, and positive and negative psychosocial functioning. Results provided support for five meaningful yet distinguishable profiles. A strong generalizability of the cluster solution was found across age, and partial generalizability was found across gender and ethnicity. Furthermore, the five profiles showed specific patterns in relation to positive and negative psychosocial functioning. Specifically, respondents with profiles high on Presence of Meaning showed the most adaptive psychosocial functioning, whereas respondents with profiles where meaning was largely absent showed maladaptive psychosocial functioning. The present study provided additional evidence for prior research concerning the complex relationship between Presence of Meaning and Search for Meaning, and their relation with psychosocial functioning. Our results offer a partial clarification of the nature of the Search for Meaning process by distinguishing between adaptive and maladaptive searching for meaning in life.
