Daily and trait rumination: diurnal cortisol patterns in adolescent girls

Rumination is a maladaptive form of emotion regulation associated with psychopathology. Research with adults suggests that rumination covaries with diurnal cortisol rhythms, yet this has not been examined among adolescents. Here, we examine the day-to-day covariation between rumination and cortisol, and explore whether trait rumination is associated with alterations in diurnal cortisol rhythms among adolescent girls. Participants (N?=?122) provided saliva samples 3 times per day over 3 days, along with daily reports of stress and rumination, questionnaires assessing trait rumination related to peer stress, and diagnostic interviews assessing depression and anxiety. Greater rumination than usual during the day was associated with lower cortisol awakening responses the following morning, but this effect was not significant after accounting for wake time and an objective measure of adherence to the saliva sampling protocol. Trait rumination was associated with lower average cortisol levels at waking and flatter diurnal slopes, accounting for wake time, protocol compliance, and other factors. These patterns may help to explain why rumination is related to the development of psychopathology.     

Understanding online child pornography use: Applying sexual offense theory to internet offenders

This review outlines the links between contemporary etiological and offense-process theories of child sexual abuse and our current knowledge of individuals who commit offenses related to online child pornography. First, we integrate previous behavioral typologies into a four-category internet offender typology. Second, we summarize development of etiological theory and evaluate the strengths and weaknesses of these theories in explaining the child pornography offender. Third, we outline the potential situational and ecological factors relating to the online environment that may also be a cause for the development and maintenance of prurient online behavior. Fourth, we review theories of the offense process and apply these to research into the modus operandi of child pornography offenders. Finally, we examine the usefulness of this approach in the assessment of risk and the treatment of online offenders.     

Folk theory of social change

People have a folk theory of social change (FTSC). A typical Western FTSC stipulates that as a society becomes more industrialized, it undergoes a natural course of social change, in which a communal society marked by communal relationships becomes a qualitatively different, agentic society where market‐based exchange relationships prevail. People use this folk theory to predict a society's future and estimate its past, to understand contemporary cross‐cultural differences, and to make decisions about social policies. Nonetheless, the FTSC is not particularly consistent with the existing cross‐cultural research on industrialization and cultural differences, and needs to be examined carefully.     

Perceptions of the Woman Who Breastfeeds: The Role of Erotophobia,Sexism, and Attitudinal Variables

Perceptions of breastfeeding women were studied in a sample of 201 predominately European American college students. Both men and women had very positive perceptions of breastfeeding women as compared to bottlefeeding women. As predicted, erotophobic women and men had less favorable impressions of the breastfeeding woman than did erotophilic individuals. Men, but not women, who scored high on Glick and Fiske's Benevolent Sexism or Hostile Sexism scales (Glick & Fiske, 1996) had more favorable impressions of the breastfeeding woman than did those with low scores. As predicted, this effect was larger for Benevolent Sexism than for Hostile Sexism. No relationships were found between impressions of breastfeeding women and the Hostility Toward Women Scale (Lonsway & Fitzgerald, 1995) or the Trait Guilt and Moral Standards scales (Jones, Schratter, & Kugler, 2000). The results supported hypotheses that sexualization of the breast, discomfort with sexual stimuli, and sexist attitudes are related to perceptions of the breastfeeding woman.     

Individual differences in mature readers in reading, spelling, and grapheme-phoneme conversion

Individual differences in word recognition, spelling, verbal reasoning, frequency of print exposure, phonological skills, Gestalt processing and semantic processing were examined in 110 university undergraduates. Most reading and phonological tasks involved making sequences of lexical decisions through lists of common stimuli within set time limits. The test measures were percentages correct adjusting for chance. The main findings were as follows: First, there is a substantial “Matthew effect” in that good readers were also good at spelling, good at handling the meaning of words, and appeared to have had the most print exposure. Second, phonological skills appear to be independent of lexical skills. Furthermore, within these phonological skills there appear to be two components, one that is automatic, and one that is more of a conscious operation.     

Inflammation, glutamate, and glia in depression: a literature review

Multiple lines of evidence suggest that inflammation and glutamate dysfunction contribute to the pathophysiology of depression. In this review we provide an overview of how these two systems may interact. Excess levels of inflammatory mediators occur in a subgroup of depressed patients. Studies of acute experimental activation of the immune system with endotoxin and of chronic activation during interferon-alpha treatment show that inflammation can cause depression. Peripheral inflammation leads to microglial activation which could interfere with excitatory amino acid metabolism leading to inappropriate glutamate receptor activation. Loss of astroglia, a feature of depression, upsets the balance of anti- and pro-inflammatory mediators and further impairs the removal of excitatory amino acids. Microglia activated by excess inflammation, astroglial loss, and inappropriate glutamate receptor activation ultimately disrupt the delicate balance of neuroprotective versus neurotoxic effects in the brain, potentially leading to depression.     

Comparison of blocking strategies informed by precursor assessment to decrease pica

Pica is dangerous behavior and often maintained by automatic reinforcement. We conducted a latency functional analysis (FA) using safe consumption items to verify that pica was maintained in part by automatic reinforcement and exclude participants for whom pica was likely maintained solely by attention. Next, we identified precursors to pica through a probability analysis and conducted a brief blocking assessment for participants' whose pica occurred in the alone and attention conditions of the FA. Finally, we compared blocking precursors with pica, touching an inedible item and the pica itself. Results showed that five of the six participants' pica was likely maintained by automatic reinforcement, and pica decreased during the brief blocking assessment for three of four participants. Results of the blocking comparison showed that blocking behaviors earlier in the response hierarchy was as effective as only blocking pica attempts for two participants and more effective for one participant.     

Creating Through Deviancy or Adjustment? The Link between Personality Profile Normativeness and Creativity

Does deviancy or adjustment predict creativity? To address this question, we tested the association between personality profile normativeness (similarity between one's personality profile and the average profile—a proxy for the deviancy–adjustment continuum) and creativity across four different samples (total N = 348 768). We used a wide range of creativity measures, including self‐reported, informant‐reported, behavioural, and occupational creativity, as well as several essential statistical controls (i.e., demographics, socio‐economic background, intelligence, and life satisfaction). Furthermore, we employed both cross‐sectional and longitudinal designs, including samples of college students and representative adult populations. We found that people who had more normative personality profiles were more creative. However, this association only held within modality (i.e. when both personality and creativity were either self‐reported or informant‐reported). We did not find robust associations between personality profile normativeness and laboratory‐based behavioural measures of creativity, occupational creativity, or creative achievements. We discuss alternative explanations for the observed adjustment–creativity link, specifically, implicit theories of creativity and person perception biases (halo effects). Notably, the findings did not support the idea that deviancy breeds creativity, suggesting that the famed ‘mad genius’ hypothesis might not hold among the general population. © 2019 European Association of Personality Psychology
