Subjective Uncertainty as a Predictor of Specific Exploration

This study compared two measures of subjective uncertainty to a measure of experimenter-defined uncertainty in their prediction of specific exploration in children (N = 93 boy and girls aged 6–7 to 10–11 years old). As suggested by Berlyne, subjective uncertainty was hypothesized to be a more effective measure in predicting specific exploratory behavior than experimenter-defined uncertainty, since it accounts for the contributions of the individual engaged in the exploration. Results supported the hypothesis, indicating that both measures of subjective uncertainty were significantly better predictors of specific exploration than an experimenter-defined measure.     

Negotiating Health-Related Uncertainties: Biomedical and Religious Sources of Information and Support

This article explores how people experience health-related uncertainties and how they look to biomedical and religious sources of information in response. Data were gathered in a larger project focused on spirituality in everyday life. Respondents were not asked any direct questions about their health or health care, but almost all of the 95 participants brought up the topics in response to other questions. About one-third spoke of being uncertain about some aspect of their health or healthcare. We explore the health-related topics about which people were uncertain and how they looked to biomedical and religious sources of information, most often seeing the religious as a support for the biomedical. We outline the range of ways they experienced God in this process pointing to the multiple complex ways they make sense of health-related uncertainties.     

Gender Differences in Delinquency in Early,Middle, and Late Adolescence: An Exploration of Parent and Friend Relationships

Researchers often examine juvenile delinquency without considering the developmental differences between early, middle, and late adolescence. Much research suggests that relationships with parents and friends differ throughout adolescence; however, no research to date has explored how gender differences in friend and parent relationships throughout the stages of adolescence may affect delinquent involvement. In the current project, I utilize a large sample of adolescents to explore the ways friend and parental relationships differ among young men and women throughout adolescence and how these changing relationships affect gender differences in delinquency. I find that both friend relationships and parent–child bonding affect delinquency and that these relationships differ by both gender and stage of adolescence.     

The moderating effect of humor style on the relationship between interpersonal predictors of suicide and suicidal ideation

This study investigated how positive and negative humor styles relate to suicidal ideation, thwarted belongingness, and perceived burdensomeness. Analyses indicated that affiliative and self-defeating humor style moderated the relationships between thwarted belongingness and suicidal ideation as well as perceived burdensomeness and suicidal ideation when controlling for depression. The clinical importance of assessing and tracking humor styles as potential coping mechanisms against suicidal thinking is discussed.     

Randomized controlled trial evaluating the effectiveness of a web-based stress management program among community college students

Background and Objectives: This study evaluated the effectiveness of a web-based stress management program among community college students that focused on increasing perceived control over stressful events. Design: Students (N = 257) were randomly assigned to a Present Control Intervention or a Stress-information only comparison group. Methods: Primary outcomes were perceived stress and stress symptoms; secondary outcomes were depression and anxiety. Self-report measures were completed online at preintervention, postintervention, and three-week follow-up. Intervention effects were estimated using linear mixed models. Seventy-five percent of the sample (n = 194) completed the pretest and comprised the intent-to-treat sample. Results: Participants in the intervention group reported significant increases in present control, and significant decreases in all four primary and secondary outcome measures from baseline to postintervention and follow-up. Within-group effect sizes were small to medium at postintervention (mean d = –.34) and follow-up (mean d = –.49). The mean between-group effect size on the four outcome measures was d = .35 at postintervention but d = .12 at follow-up, due to unexpected decreases in distress in the comparison group. Conclusions: Our online program is a cost-effective mental health program for college students. Limitations and future direction are discussed.     

Working memory, fluid intelligence, and impulsiveness in heavy media multitaskers

Ophir, Nass, and Wagner (Proceedings of the National Association of Sciences 106:15583–15587, 2009) reported that individuals who routinely engage in multiple forms of media use are actually worse at multitasking, possibly due to difficulties in ignoring irrelevant stimuli, from both external sources and internal representations in memory. Using the media multitasking index (MMI) developed by Ophir et al., we identified heavy media multitaskers (HMMs) and light media multitaskers (LMMs) and tested them on measures of attention, working memory, task switching, and fluid intelligence, as well as self-reported impulsivity and self-control. We found that people who reported engaging in heavy amounts of media multitasking reported being more impulsive and performed more poorly on measures of fluid intelligence than did those who did not frequently engage in media multitasking. However, we could find no evidence to support the contention that HMMs are worse in a multitasking situation such as task switching or that they show any deficits in dealing with irrelevant or distracting information, as compared with LMMs.     

Expectations from preceding prosody influence segmentation in online sentence processing

Previous work examining prosodic cues in online spoken-word recognition has focused primarily on local cues to word identity. However, recent studies have suggested that utterance-level prosodic patterns can also influence the interpretation of subsequent sequences of lexically ambiguous syllables (Dilley, Mattys, & Vinke, Journal of Memory and Language, 63:274–294, 2010; Dilley & McAuley, Journal of Memory and Language, 59:294–311, 2008). To test the hypothesis that these distal prosody effects are based on expectations about the organization of upcoming material, we conducted a visual-world experiment. We examined fixations to competing alternatives such as pan and panda upon hearing the target word panda in utterances in which the acoustic properties of the preceding sentence material had been manipulated. The proportions of fixations to the monosyllabic competitor were higher beginning 200 ms after target word onset when the preceding prosody supported a prosodic constituent boundary following pan-, rather than following panda. These findings support the hypothesis that expectations based on perceived prosodic patterns in the distal context influence lexical segmentation and word recognition.     

Improving the Transportability of CBT for Internalizing Disorders in Children

Research provides strong support for the efficacy and effectiveness of cognitive behavioral therapy (CBT) for the treatment of childhood internalizing disorders. Given evidence for limited dissemination and implementation of CBT outside of academic settings, efforts are underway to improve its transportability so that more children with mental health needs may benefit from treatment. Creative modifications to existing treatments aim to deliver CBT for anxiety disorders and depression in a more transportable format. Notable progress has been made within the areas of computerized CBT, camp-based CBT, school-based CBT, and CBT delivered through primary care settings. These approaches are discussed within the context of key elements of transportability that are particularly germane to the dissemination and implementation of child treatments.     

Parental goals and talk with toddlers

Myriad studies support a relation between parental beliefs and behaviours. This study adds to the literature by focusing on the specific relationship between parental goals and their communication with toddlers. Do parents with different goals talk about different topics with their children? Parents' goals for their 30‐month olds were gathered using semi‐structured interviews with 47 primary caregivers, whereas the topics of conversations that took place during interactions were investigated via coding videotapes of observations in the home. Parents' short‐ and long‐term goals spanned several areas, including educational, social–emotional, developmental and pragmatic goals. Parental utterances most frequently focused on pragmatic issues, followed by play and academic topics. Parents who mentioned long‐term educational goals devoted more of their talk to academic topics and less to pragmatic topics, controlling for socio‐economic status. Thus, parental goals differ and these differences relate to the conversations parents engage in with their children. Copyright © 2010 John Wiley & Sons, Ltd.     

An investigation of the partial-assignment completion effect on students' assignment choice behavior

This study was designed to investigate the partial assignment completion effect. Seventh-grade students were given a math assignment. After working for 5 min, they were interrupted and their partially completed assignments were collected. About 20 min later, students were given their partially completed assignment and a new, control assignment that contained the same number of equivalent problems that were incomplete on their partially completed assignment. Students were told that they would have to complete an assignment but could choose which assignment they completed. Significantly more students chose their partially completed assignment. Theoretical and applied implications and directions for future research are discussed.
