Number of Sexual Partners and Social Disorganization: A Developmental Trajectory Approach

Utilizing a developmental trajectory approach, this study examines whether or not the perceived presence of social disorganization within communities contributes to the experience of having multiple sexual partners. The sample consists of African-American self-reports (n = 402) originating from the National Longitudinal Survey of Youth (NLSY79). Analysis centers on responses from individuals who were ages 15 to 17 in 1998, 17 to 19 in 2000, 19 to 21 in 2002, 21 to 23 in 2004, 23 to 25 in 2006, and 25 to 27 in 2008. Following trajectory analysis of their reported number of sexual partners and perceptions of social disorganization, three groups are identified, showing variations in perceptions and number of sexual partners. Overall, results from these groups indicate that perceived social disorganization among African Americans has some impact on their number of sexual partners. Implications and directions for future research concerning social disorganization and public health are discussed.     

Developmental Trajectories of Maternal and Paternal Attachment and Delinquency in Adolescence

The present study sought to address two research questions: (1) Are there distinct trajectories of maternal and paternal attachment among adolescents? And if so, (2) How do these trajectories of maternal and paternal attachment relate to delinquent trajectories over the ages of 12 to 16? Using a subsample (n = 383) of the longitudinal Gang Resistance Education and Training (GREAT) data, the results from semi-parametric group-based modeling (SPGM) suggested five groups of maternal attachment, where one trajectory exhibited little to no maternal attachment; another group appeared to have an initially low rate of maternal attachment but increased rather noticeably over time; a third trajectory demonstrated high initial levels of maternal attachment but a general decline over time; and the last two groups exhibited high and rather stable rates of maternal attachment, although one of these groups showed evidence of a decline. Comparatively, the same number of trajectory groups was estimated for paternal attachment, with relatively similar patterns over time as for the maternal attachment trajectories, with the exception of one trajectory that appeared to decline initially before demonstrating a substantial increase. Finally, the results from the joint trajectory analysis indicated that as maternal and paternal attachment increased the likelihood for delinquency decreased. Implications for future research and policy are also discussed.     

Low Self-control and Deviance: Examining the Moderation of Social Support from Parents

Drawing on self-report survey data from a sample of 425 college students in 2001, this study examines whether parental support can moderate the link between low self-control and deviance. Using multiple measures of low self-control and parental support and item parcels of deviance, structural equation models are developed to arrive at the results. Results reveal that parental support does not completely moderate the link between low self-control and deviance. Importantly, we find that parental support can reduce the link that low self-control has with deviance, suggesting that this is a measure that may be manipulated to reduce instances of deviance.     

Digital Piracy: An Examination of Three Measurements of Self-Control

Research has shown a link between digital piracy and self-control. However, the research focuses on only one version of self-control theory. The purpose of the present study is to examine the link between self-control and digital piracy. Using data from 358 college students, this study shows that all 3 measures of self-control help us understand the link between self-control and digital piracy. The results indicate that illuminating the factors that could be inhibitions and developing strong social bonds can reduce the likelihood of digital piracy.     

Automatic social behavior as motivated preparation to interact

The authors propose that automatic social behavior may result from perceivers preparing to interact with primed social group members. In Study 1, participants primed with a disliked outgroup (gay men) showed evidence of interaction preparation (aggression) rather than direct stereotypic trait expression (passivity). In Study 2, participants with implicit positive attitudes toward the elderly walked more slowly after "elderly" priming, but participants with negative attitudes walked more quickly, results consistent with a preparatory account; the reverse was found priming "youth." Study 3 demonstrated that the accessibility of a primed category follows a pattern more consistent with that of goal-related constructs (including post-goal-fulfillment inhibition) than that of semantically primed constructs. Implications for the function of stored knowledge are discussed.     

Value from hedonic experience and engagement

Recognizing that value involves experiencing pleasure or pain is critical to understanding the psychology of value. But hedonic experience is not enough. I propose that it is also necessary to recognize that strength of engagement can contribute to experienced value through its contribution to the experience of motivational force--an experience of the intensity of the force of attraction to or repulsion from the value target. The subjective pleasure/pain properties of a value target influence strength of engagement, but factors separate from the hedonic properties of the value target also influence engagement strength and thus contribute to the experience of attraction or repulsion. These additional sources of engagement strength include opposition to interfering forces, overcoming personal resistance, using the right or proper means of goal pursuit, and regulatory fit between the orientation and manner of goal pursuit. Implications of the contribution of engagement strength to value are discussed for judgment and decision making, persuasion, and emotional experiences.     

Culture and egocentric perceptions of fairness in conflict and negotiation

In this article, the authors advanced a cultural view of judgment biases in conflict and negotiation. The authors predicted that disputants' self-serving biases of fairness would be more prevalent in individualistic cultures, such as the United States, in which the self is served by focusing on one's positive attributes to "stand out" and be better than others, yet would be attenuated in collectivistic cultures, such as Japan, where the self is served by focusing on one's negative characteristics to "blend in" (S. J. Heine, D. R. Lehman, H. R. Markus, & S. Kitayama, 1999). Four studies that used different methodologies (free recall, scenarios, and a laboratory experiment) supported this notion. Implications for the science and practice of negotiation are discussed.     

Effects of repetitive hypoglycemia on neuroendocrine response and brain tyrosine hydroxylase activity in the rat

Hypoglycemia-associated autonomic failure (HAAF) is a syndrome of acute adaptation to a metabolic stressor, in which neuroendocrine responses to repetitive hypoglycemic bouts are blunted. The CNS mechanisms that contribute to HAAF are unknown. In the present study, we modeled HAAF in the rat and measured the activity of tyrosine hydroxylase (TH) as an index of acute noradrenergic activation, to test the hypothesis that noradrenergic activation of the hypothalamus might be impaired. In association with a significant counter-regulatory response to a single bout of hypoglycemia (elevated corticosterone, catecholamines, and glucagon), TH activity was elevated overall in brainstem NE cell body areas and hypothalamus. With multiple hypoglycemic episodes in a 24 h period, the counter-regulatory response was blunted, and hypothalamic TH activity was comparable to that of saline-infused controls. In a similar paradigm, multiple bouts of CNS neuroglucopenia did not blunt the hyperglycemic or corticosterone responses, and were required for elevation of TH activity. This alternate response pattern suggests that insulin-induced hypoglycemia and cerebral neuroglucopenia represent somewhat different metabolic stressors at the CNS.     

An introduction to Chinese psychology--its historical roots until the present day

In this article the authors review the historical development of Chinese psychology. China's long history as a country immersed in the study of psychological issues is well known and has had an influence on developments in the field of psychology around the world. Modern Chinese psychology, however, was imported from the West and the Soviet Union and has been closely linked with China's social environment and changes of national policy. Today Chinese psychology is still in a preliminary stage. Despite difficulties that may impede its future development, the importance of psychology in the modernization of China has been widely recognized.
