Sex differences in impulsivity: a meta-analysis

Men are overrepresented in socially problematic behaviors, such as aggression and criminal behavior, which have been linked to impulsivity. Our review of impulsivity is organized around the tripartite theoretical distinction between reward hypersensitivity, punishment hyposensitivity, and inadequate effortful control. Drawing on evolutionary, criminological, developmental, and personality theories, we predicted that sex differences would be most pronounced in risky activities with men demonstrating greater sensation seeking, greater reward sensitivity, and lower punishment sensitivity. We predicted a small female advantage in effortful control. We analyzed 741 effect sizes from 277 studies, including psychometric and behavioral measures. Women were consistently more punishment sensitive (d = -0.33), but men did not show greater reward sensitivity (d = 0.01). Men showed significantly higher sensation seeking on questionnaire measures (d = 0.41) and on a behavioral risk-taking task (d = 0.36). Questionnaire measures of deficits in effortful control showed a very modest effect size in the male direction (d = 0.08). Sex differences were not found on delay discounting or executive function tasks. The results indicate a stronger sex difference in motivational rather than effortful or executive forms of behavior control. Specifically, they support evolutionary and biological theories of risk taking predicated on sex differences in punishment sensitivity. A clearer understanding of sex differences in impulsivity depends upon recognizing important distinctions between sensation seeking and impulsivity, between executive and effortful forms of control, and between impulsivity as a deficit and as a trait.     

Promoting exercise behavior among Chinese youth with hearing loss: a randomized controlled trial based on the transtheoretical model

The transtheoretical model proposes that behavior change is experienced as a series of stages. Interventions tailored to these stages are most likely to be effective in progressing people through the model's hypothesized behavior change continuum. In this study, a stage-tailored, 12-week, exercise behavior intervention based on the transtheoretical model was conducted among a sample of 150 Chinese youth with hearing loss. Participants were randomized into an intervention or control group with all the core transtheoretical model constructs assessed pre- and post-intervention. Participants in the intervention group showed greater advances in their stage of exercise behavior change, decisional balance, and processes of change use compared to those in the control group. The intervention, however, was insufficient for increasing participants' self-efficacy for exercise behavior. The findings partially support the utility of the theory-based intervention for improving the exercise behavior of Chinese youth with hearing loss, while simultaneously helping to identify areas in need of improvement for future applications.     

Viewing time through the lens of the self: The fit effect of self‐construal and temporal distance on task perception

This paper describes how different self‐construals influence people's perception of temporal distance and in turn their task evaluation. We hypothesize that people with a more accessible interdependent (vs. independent) self‐construal perceive future events as temporally more proximal, and that people's reaction toward a task is intensified when the temporal distance to the task matches (vs. mismatches) their self‐construal. Across four studies, we showed that individuals with a more accessible interdependent self‐construal (Study 1) and East Asians (Study 2) perceived future events as more proximal than those with a more accessible independent self‐construal and European Americans. Further, when considering a task at a temporal distance that fits their self‐construal, individuals perceived a pleasant task as more motivating (Study 3) and an unpleasant task as less motivating (Study 4).

The axiomatic method,the order of concepts and the hierarchy of sciences: an introduction

We offer an overview of some ways of examining the connections between stance and rationality, by surveying recent work on four central topics: (a) the very idea of a stance, (b) the relations between stances and voluntarism, (c) the metaphysics and epistemology that emerge once stances are brought to center stage, and (d) the role that emotions and phenomenology play in the empirical stance.     

Disconnections of African American Public Housing Residents: Connections to Physical Activity, Dietary Habits and Obesity

African American (AA) and low SES populations report poor health behaviors and outcomes. This study aimed to increase understanding of barriers to participating in healthful behaviors and programs in AA residents of public housing. Twenty two apparently healthy, AA residents (50% female, M = 43.9 years) completed in depth interviews, which were taped, transcribed and analyzed using a constant comparison approach. Residents demonstrated some awareness of health recommendations, but described limited adherence. Physical activity for recreation was reported as primarily for youth, with adults engaging in limited physical activity (primarily incidental to other activities). Barriers reported by residents were both personal and environmental. Few residents were aware of local neighborhood opportunities for physical activity or healthful eating. Future efforts should focus on increasing understanding of health promoting behaviors and awareness and efficacy of residents to connect with the resources of their surrounding communities.     

Number of sense effects of Chinese disyllabic compounds in the two hemispheres

The current study manipulated the visual field and the number of senses of the first character in Chinese disyllabic compounds to investigate how the related senses (polysemy) of the constituted character in the compounds were represented and processed in the two hemispheres. The ERP results in experiment 1 revealed crossover patterns in the left hemisphere (LH) and the right hemisphere (RH). The sense facilitation in the LH was in favor of the assumption of single-entry representation for senses. However, the patterns in the RH yielded two possible interpretations: (1) the nature of hemispheric processing in dealing with sublexical sense ambiguity; (2) the semantic activation from the separate-entry representation for senses. To clarify these possibilities, experiment 2 was designed to push participants to a deeper level of lexical processing by the word class judgment. The results revealed the sense facilitation effect in the RH. In sum, the current study was in support of the single-entry account for related senses and demonstrated that two hemispheres processed sublexical sense ambiguity in a complementary way.     

The use of stereotypes and individuating information in political person perception

This article introduces the political person perception model, which identifies conditions under which perceivers rely on stereotypes (party membership), individuating information (issue position), or both in political person perception. Three studies supported the model's predictions. Study 1 showed that perceivers gave primacy to target information that was narrowly relevant to a judgment, whether that information was stereotypic or individuating. Study 2 found that perceivers relied exclusively on individuating information when it was narrowly relevant to the judgment and relied on both stereotype and individuating information when individuating information was not narrowly relevant to the judgment but did imply a political ideology. Study 3 replicated these findings in a more ecologically valid context and showed that people relied on party information in the absence of narrowly relevant policy positions and when individuating information did not imply a political ideology. Implications for political person perception and theories of stereotyping are discussed.     

Emerging effortful control in toddlerhood: the role of infant orienting/regulation, maternal effortful control, and maternal time spent in caregiving activities

Latent growth modeling (LGM) was used to examine the contribution of changes in infant orienting/regulation (O/R) to the emergence of toddler effortful control (EC), the contributions of maternal EC to the development of infant O/R and the emergence of toddler EC, the influence of maternal time spent in caregiving activities on toddler EC and the slope of infant O/R, and the contribution of maternal EC to subsequent maternal time spent in caregiving activities. Mothers from 158 families completed a self-report measure of EC when their infants were 4 months of age, a measure of infant O/R when their infants were 4, 6, 8, 10, and 12 months of age, and a measure of toddler EC when their children reached 18 months of age. Information concerning maternal time spent in various interactive caregiving activities was collected when infants were 6 months old. Results indicated higher maternal EC predicted interindividual differences in the intercept (i.e., higher intercepts), but not slope, of infant O/R and that higher maternal EC, higher infant O/R intercept, and higher infant O/R slope contributed to higher toddler EC. Furthermore, higher maternal EC predicted greater maternal time spent in interactive caregiving activities with their infants and greater maternal time in interactive caregiving with infants also contributed to higher toddler EC after controlling for maternal EC. These findings contribute to the understanding of the influence of maternal EC, directly and through caregiving, on toddler EC. Additional implications as they are related to early developing regulatory aspects of temperament are discussed.     

Age and gender differences in adolescents' homework experiences

Extant data collected through the Experience Sampling Method were analyzed to describe adolescents' subjective experiences of homework. Analyses explored age and gender differences in the time adolescents spend doing homework, and the situational variations (location and companions) in adolescents' reported concentration, effort, interest, positive affect and stress while doing homework. Regarding age differences, middle school students reported more positive experiences when homework was done with companions and in locations other than home, whereas high school students reported more positive experiences when homework was done alone and at home. Regarding gender differences, girls, regardless of age, reported greater stress than boys when doing homework alone, and lower stress when doing homework with friends. High school girls reported lower interest than middle school boys when doing homework alone. Findings provide an understanding of age and gender differences in adolescents' perceptions of homework, which might help educators and parents structure engaging homework environments.     

Youth’s Help-Seeking Intentions for ADHD and Depression: Findings from a National Survey

This study investigates the role that youth-level factors play in predicting help-seeking intentions in a nationally representative sample. Eleven help-seeking intentions were examined separately by target conditions (ADHD and depression), gender, race/ethnicity, and self-reported diagnosed/non-diagnosed in respect to the target conditions, and interaction effects were tested. Using factor analysis, a traditional help-seeking scale was created, which captured four help-seeking items, and predictive power of youth-level factors in accounting for traditional help-seeking was tested. Study findings provide practitioners and researchers with fresh evidence on what youth-level factors are associated with which help-seeking intentions, and illustrate the challenges involved in better understanding the complexity of the help-seeking process among youth in the context of ADHD/Depression. With increased understanding of youth’s perceptions and the complexity of their help-seeking behavior, community-based efforts to develop effective strategies that support active help-seeking behavior and eliminate barriers to appropriate care can have a greater likelihood of success.
