Risk of suicidal ideation in adolescents with both self-asphyxial risk-taking behavior and non-suicidal self-injury

This study examined adolescent participation in self-asphyxial risk-taking behaviors (SAB), sometimes known as the "choking game," and its relationship with other adolescent risk behaviors, including non-suicidal self-injury (NSSI). Researchers proposed that participation in SAB and NSSI would be associated with suicidal behavior, disordered eating, and substance use. Using a large community-based sample, results revealed preliminary associations between SAB and other risk-taking behaviors. Adolescents who had engaged in both SAB and NSSI reported more concurrent risk behaviors than adolescents who participated in only one of the behaviors or neither behavior. Results indicate that greater awareness of SAB is important, and continued research can evaluate the possible link between the behavior and risk for suicide.     

Assessing the forms and functions of aggression using self-report: factor structure and invariance of the Peer Conflict Scale in youths

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed.     

Flicker-light induced visual phenomena: frequency dependence and specificity of whole percepts and percept features

Flickering light induces visual hallucinations in human observers. Despite a long history of the phenomenon, little is known about the dependence of flicker-induced subjective impressions on the flicker frequency. We investigate this question using Ganzfeld stimulation and an experimental paradigm combining a continuous frequency scan (1–50 Hz) with a focus on re-occurring, whole percepts. On the single-subject level, we find a high degree of frequency stability of percepts. To generalize across subjects, we apply two rating systems, (1) a set of complex percept classes derived from subjects’ reports and (2) an enumeration of elementary percept features, and determine distributions of occurrences over flicker frequency. We observe a stronger frequency specificity for complex percept classes than elementary percept features. Comparing the similarity relations among percept categories to those among frequency profiles, we observe that though percepts are preferentially induced by particular frequencies, the frequency does not unambiguously determine the experienced percept.     

‘No fair, copycat!’: what children’s response to plagiarism tells us about their understanding of ideas

Adults believe that plagiarizing ideas is wrong, which requires an understanding that others can have ideas and that it is wrong to copy them. In order to test when this understanding emerges, we investigated when children begin to think plagiarism is wrong. In Study 1, children aged 7, 9 and 11 years old, as well as adults, disliked someone who plagiarized compared to someone who drew an original drawing or someone who drew an identical picture by chance. Study 2 investigated the same question with younger children, focusing on children aged 3–6 years old. Children aged 5–6 years old evaluated plagiarizers negatively relative to unique drawers, but 3–4-year-olds did not. Study 3 replicated the findings from Study 2 and found that children justify their negative evaluations of plagiarizers by mentioning concerns over copying. These experiments provide evidence that, by age 5 years old, children understand that others have ideas and dislike the copying of these ideas.     

Disentangling the adult attention-deficit hyperactivity disorder endophenotype: parametric measurement of attention

Attention deficit hyperactivity disorder (ADHD) persists frequently into adulthood. The decomposition of endophenotypes by means of experimental neuro-cognitive assessment has the potential to improve diagnostic assessment, evaluation of treatment response, and disentanglement of genetic and environmental influences. We assessed four parameters of attentional capacity and selectivity derived from simple psychophysical tasks (verbal report of briefly presented letter displays) and based on a "theory of visual attention." These parameters are mathematically independent, quantitative measures, and previous studies have shown that they are highly sensitive for subtle attention deficits. Potential reductions of attentional capacity, that is, of perceptual processing speed and working memory storage capacity, were assessed with a whole report paradigm. Furthermore, possible pathologies of attentional selectivity, that is, selection of task-relevant information and bias in the spatial distribution of attention, were measured with a partial report paradigm. A group of 30 unmedicated adult ADHD patients and a group of 30 demographically matched healthy controls were tested. ADHD patients showed significant reductions of working memory storage capacity of a moderate to large effect size. Perceptual processing speed, task-based, and spatial selection were unaffected. The results imply a working memory deficit as an important source of behavioral impairments. The theory of visual attention parameter working memory storage capacity might constitute a quantifiable and testable endophenotype of ADHD.     

The effect of humorous instructional materials on interest in a math task

Two studies tested the effect of humor, embedded in learning materials, on task interest. College student participants (N _{Study 1} = 359, N _{Study 2} = 172) learned a new math technique with the presence or absence of humor in the learning program and/or test instructions. Individual interest in math was measured initially and also tested as a factor. The results showed that the effect of humor in the learning program depended on individual interest in math. Humor raised task interest for those with low individual interest in math but slightly lowered task interest for those with high individual interest in math. Mediating variables of this effect were tested across both studies. Although the mediating variables showed inconsistency, humor may affect task interest through affective responses immediately following the instruction, rather than in subsequent interaction with the task.     

The Impact of Passing the Professional in Human Resources Exam on Early Career Success for Undergraduates Entering the Human Resource Field

This study investigates the impact of passing the Professional in Human Resources (PHR) certification exam on the early career success of recent college graduates. Data were gathered from alumni of three Midwestern universities who earned an undergraduate degree in business administration (i.e., BBA) with a major in human resources. The survey was designed to measure early career success indicators including finding a job in the HR field, starting salary, and number of promotions. Results reveal that the probability of one's first job after graduation being in human resources was significantly greater for those who had passed the PHR exam compared with those who did not pass or did not take the exam. Passing the PHR exam was not associated with significant differences in starting salary or early career promotions. Implications, study strengths and limitations, and suggestions for future research are discussed.     

Emotional and cognitive information processing: relations to behavioral performance and hippocampal long-term potentiation in vivo during a spatial water maze training in rats

Emotionality as well as cognitive abilities contribute to the acquisition and retrieval of memories as well as to the consolidation of long-term potentiation (LTP), a cellular model of memory formation. However, little is known about the timescale and relative contribution of these processes. Therefore, we tested the effects of weak water maze training, containing both emotional and cognitive demands, on LTP in the hippocampal dentate gyrus. The population spike amplitude (PSA)-LTP was prolonged in all rats irrespective of whether they memorized the platform position or not, whereas the field excitatory postsynaptic potential (fEPSP)-LTP was impaired in good learners and enhanced in poor learners. We then dissociated the behavioral performance of rats during the water maze task by principal component analysis and by means of stress hormone concentrations into underlying "emotional" and "cognitive" factors. PSA-LTP was associated with "emotional" and fEPSP-LTP with "cognitive" behavior. PSA-LTP was depotentiated after the blockade of corticosterone binding mineralocorticoid receptors (MRs) in trained animals, while fEPSP-LTP was unaffected. These results suggest that synaptic processing and encoding of emotional information in the hippocampal dentate gyrus is realized fast and further information transfer is detectable by the reinforcement of PSA-LTP, whereas that of cognitive memories is long lasting.     

A Blueprint for Social Cognitive Development

ABSTRACT— The field of social cognitive development (SCD) has historically failed to emerge as a dominant approach in developmental psychology. We take this opportunity to articulate the assumptions, goals, and contributions of SCD with the aim of invigorating research from this perspective. We begin by describing the current landscape of social and cognitive development, suggesting what they have and have not given us. We then outline major goals of the social cognitive developmental approach and walk through examples of successful SCD research. Finally, we examine the unique potential of the social cognitive approach to cross-fertilize social and cognitive development (as well as related fields such as social psychology and neuroscience) and to answer new questions about development.     

Integrating Social Information Processing and Attachment Style Research with Cognitive-behavioral Couple Therapy

The majority of the empirically validated interventions for relational distress focus primarily upon improving behavioral functioning, particularly couples’ communication patterns in conflict situations. However, although communication is highly predictive of relationship distress and later divorce, research on the effectiveness of premarital and marital interventions based on communication training has shown limited results. Therefore, although the skills-based approaches can be effective in treating relational discord and instability, they also often neglect another potentially powerful mechanism in the development of relational distress: the social cognitions and/or schemata regarding relationships that individuals carry into their marriages that stem from negative attachment experiences. Thus, this article describes how blending information gleaned from attachment style research with the body of literature addressing social information processing can enhance current methods for the treatment of relational discord. The existing research on adult romantic attachment styles is placed within a social-cognitive information processing framework and a case study demonstrating the utility of this approach with difficult couples is described.
