Spectral weights and the profile bowl

In these experiments, listeners detected changes in the shape of a complex spectrum that varied in overall level. With multicomponent complexes, a typical finding is that the listeners were more sensitive to changes made in the middle components of the spectrum than to changes made at either edge. We used a technique developed by Berg (1989) to estimate the weight listeners attached to the different components of the spectrum in making these judgements. For reasons not understood, the pattern of spectral weights was nearly optimum for a change made in the middle component of the spectrum and much poorer when the change occurred at either edge.     

“You're not gay; You're a child of god”: Microaggressions experienced by LGBTQ+ teens and their parents in the Church of Jesus Christ of Latter-day Saints

Like other teens in conservative religious environments, LGBTQ+ teens raised in the Church of Jesus Christ of Latter-day Saints (CJCLDS) likely experience unique microaggressions. Furthermore, like other conservatively religious parents of LGBTQ+ teens, active Latter-day Saint (LDS) parents who openly support their LGBTQ+ teens likely both witness microaggressions toward their teens and may personally experience microaggressions. The present study sought to understand parents' and teens' experiences of microaggressions in conservative religious contexts by focusing specifically on the microaggressions experienced by (a) LGBTQ+ teens raised in the CJCLDS and (b) their active LDS parents. Thematic analysis of separate interviews with 19 dyads of LGBTQ+ teens and their active LDS parents (38 total interviews) revealed various ways in which they experienced verbal, nonverbal, and environmental microaggressions. We highlight parents' and teens' shared experiences of microaggressions that may be uniquely related to their religious contexts, such as assumptions that LGBTQ+ teens or their parents are not faithful and exclusionary Church policies. Additionally, we identified microaggressions that specifically targeted parents of LGBTQ+ teens, such as comments suggesting parents should limit their support for their teens. Finally, we found that parents had vicarious experiences with microaggressions through witnessing or learning about microaggressions that targeted their teens. Findings highlight the ways that the religious contexts in which microaggressions occur can influence the way that microaggressions are communicated to and experienced by LGBTQ+ teens – and their parents.     

The surface core-level shift of the Nb(110) surface

The surface core-level shift (SCLS) of the Nb(110) surface has been determined by means of high-resolution core-level photoelectron spectroscopy of the Nb 3d5/2 core level. A SCLS of 180 +- 15 meV towards higher binding energy with respect to the bulk component was estimated by curve fitting the Nb 3d5/2 core-level spectra taken using several photon energies. The sign of the SCLS agrees with recent ab initio calculations including both initial- and finalstate effects, but the shift is significantly smaller than predicted in these calculations.     

Resilience in families in which a child is bullied

The aim of this study was to identify family resilience characteristics in families in which a child has been bullied, in the Western Cape province of South Africa. Forty-eight mothers represented their families and completed a biographical questionnaire containing an open-ended question, and seven self-report questionnaires. Results from the qualitative data showed that most of the families coped with the bullying by talking to a teacher, principal or the governing body, or by giving advice to the child who had been bullied. The quantitative results highlighted the quality of family communication, the fortitude and durability of the family unit, and the family's emphasis on being together. These findings can be utilised in interventions to strengthen families finding themselves in a similar crisis.     

Categorization of multidimensional stimuli by pigeons

Six pigeons responded in a visual category learning task in which the stimuli were dimensionally separable Gabor patches that varied in frequency and orientation. We compared performance in two conditions which varied in terms of whether accurate performance required that responding be controlled jointly by frequency and orientation, or selectively by frequency. Results showed that pigeons learned both category tasks, with average overall accuracies of 85.5% and 82% in the joint and selective control conditions, respectively. Although perfect performance was possible, responding for all pigeons fell short of optimality. Model comparison analyses showed that the General Linear Classifier (GLC; Ashby, 1992) provided a better account of responding in the joint control condition than unidimensional models, but a unidimensional model fitted better for the condition that required selective control by frequency. Our results show that pigeons' responding in a visual categorization task can be controlled jointly or selectively by stimulus dimensions, depending on reinforcement contingencies. However, analysis of residuals confirmed that systematic deviations of GLC predictions from the obtained data were present in both conditions, suggesting that an alternative account of responding in multidimensional category learning tasks may be necessary.     

Convergence of scores on the interview and questionnaire versions of the Eating Disorder Examination: a meta-analytic review

Significant discrepancies have been found between interview- and questionnaire-based assessments of psychopathology; however, these studies have typically compared instruments with unmatched item content. The Eating Disorder Examination (EDE), a structured interview, and the questionnaire version of the EDE (EDE-Q) are considered the preeminent assessments of eating disorder symptoms and provide a unique opportunity to examine the concordance of interview- and questionnaire-based instruments with matched item content. The convergence of EDE and EDE-Q scores has been examined previously; however, past studies have been limited by small sample sizes and have not compared the convergence of scores across diagnostic groups. A meta-analysis of 16 studies was conducted to compare the convergence of EDE and EDE-Q scores across studies and diagnostic groups. With regard to the EDE and EDE-Q subscale scores, the overall correlation coefficient effect sizes ranged from .68 to .76. The overall Cohen's d effect sizes ranged from .31 to .62, with participants consistently scoring higher on the questionnaire. For the items measuring behavior frequency, the overall correlation coefficient effect sizes ranged from .37 to .55 for binge eating and .90 to .92 for compensatory behaviors. The overall Cohen's d effect sizes ranged from -0.16 to -0.22, with participants reporting more binge eating on the interview than in the questionnaire in 70% of the studies. These results suggest the interview and questionnaire assess similar constructs but should not be used interchangeably. Additional research is needed to examine the inconsistencies between binge frequency scores on the 2 instruments.
