Stability in alexithymia levels: A longitudinal analysis on various emotional answers

Alexithymia refers to a specific disturbance in emotional processing that is manifested through difficulties in identifying and verbalizing feelings, and a tendency to focus and amplify the somatic sensations accompanying emotional arousal. The main purpose of the present study was to investigate the stability levels of alexithymia related to changes in emotional distress levels caused by university exams at two different times: after and during the exams. We carried out a 17-week follow-up on 36 university students, alexithymic features and self-reported emotional distress (anxiety, depression and somatic illness) were measured. Whereas emotional distress measures changed significantly during the follow-up period, the degree of alexithymia remained unchanged. We conclude therefore that alexithymia presents a constant trait in non-clinical samples, in contrast to anxiety and depression, which are state phenomena, influenced by stress levels.     

The Church of England’s Pray One for Me intercessory prayer site: a virtual cathedral?

Over the past decade there has been a growing number of studies examining the prayer content of people’s personal prayers left in intercessory church-related contexts. Since 2012, these studies have extended to include the cathedral intercessory prayer board and the online intercessory prayer site. Both ‘the cathedral’ and ‘the online site’ are distinctive contexts for intercessory prayer in terms of their openness and accessibility for a broad range of people, who are allowed to enter and use these prayer facilities. What is not known, however, is whether the cathedral prayer board and the online site are functioning in similar ways. This study presents an analysis of 500 prayers posted on the Church of England’s ‘Pray One for Me’ (POFM) website over a period of six months in 2012. The analysis employs the ap Siôn Analytic Framework for Intercessory Prayer (apSAFIP), which distinguishes among prayer intention, prayer reference, and prayer objective. The results of the analysis are compared with the results from recent cathedral studies employing the same analytic tool, and it is concluded that these two prayer contexts are functioning differently.     

Examination of the reliability and validity of the personality assessment inventory

The reliability, discriminant validity, and construct validity of the Personality Assessment Inventory (PAI) — a multidimensional self-report measure of abnormal personality traits — were examined within the Australian context. Subjects included 151 normals, 30 alcoholics, and 30 schizophrenic patients. A subsample of 70 nonpsychiatric adults responded to the PAI items twice over a test-retest interval of 28 days. The resulting median retest coefficient was 0.7, indicating less than optimal stability. The median alpha (KR₂₁) coefficient was 0.8, suggesting somewhat narrow measurement scales. A significant multivariate main effect was obtained across groups after the effects of age and gender were removed. Multiple comparisons for each of the PAI scales revealed significant differences between the respective groups, as discussed. A higher-order scale factoring did not strongly support the purported PAI structure. In reanalyses of the correlation matrices included in the Professional Manual, the purported PAI factor structure was unable to be replicated for the standardization clinical sample (N=1246), and a confirmatory factor analysis using the normative (validation) correlational data (N=1000) revealed poor fit indices, raising further concerns about construct validity.     

Unconditional respect for persons and the prediction of intergroup action tendencies

Unconditional respect for persons is an orientation that rests on the assumption that all people have intrinsic worth and deserve respect simply by their being human. This paper reports three cross‐sectional studies concerning unconditional respect in intergroup relations in three very different contexts. In all three studies, unconditional respect was positively related to positive action tendencies, and negatively related to negative action tendencies, toward other groups. Regression analyses showed that respect was a significant predictor of negative action tendencies even when attitude to the other group, social dominance orientation, empathy, and the quality and quantity of intergroup contact were statistically controlled. Moderation analyses showed that respect was particularly important under conditions of high threat. The implications of unconditional respect for intergroup relations are discussed.

Effects of explaining on children's preference for simpler hypotheses

Research suggests that the process of explaining influences causal reasoning by prompting learners to favor hypotheses that offer “good” explanations. One feature of a good explanation is its simplicity. Here, we investigate whether prompting children to generate explanations for observed effects increases the extent to which they favor causal hypotheses that offer simpler explanations, and whether this changes over the course of development. Children aged 4, 5, and 6 years observed several outcomes that could be explained by appeal to a common cause (the simple hypothesis) or two independent causes (the complex hypothesis). We varied whether children were prompted to explain each observation or, in a control condition, to report it. Children were then asked to make additional inferences for which the competing hypotheses generated different predictions. The results revealed developmental differences in the extent to which children favored simpler hypotheses as a basis for further inference in this task: 4-year-olds did not favor the simpler hypothesis in either condition; 5-year-olds favored the simpler hypothesis only when prompted to explain; and 6-year-olds favored the simpler hypothesis whether or not they explained.     

Can emotional content reduce the age gap in visual working memory? Evidence from two tasks

Ageing is associated with declines in several cognitive abilities including working memory (WM). The goal of the present study was to assess whether emotional information could reduce the age gap in the quantity and quality (precision) of representations in visual WM. Young and older adults completed a serial image recognition (SIR) task and a colour-image binding (CIB) task. Results of the SIR task showed worse performance for negative than neutral and positive images within the older group, hence enlarging the age gap in WM. In the CIB task, recall precision was lower in the old than young adults, showing an ageing decline in the quality of WM representations. Positive images tended to improve precision, but this boost was similar for both age groups. In sum, emotional content did not reduce the age gap in visual WM.     

Simplicity and probability in causal explanation

What makes some explanations better than others? This paper explores the roles of simplicity and probability in evaluating competing causal explanations. Four experiments investigate the hypothesis that simpler explanations are judged both better and more likely to be true. In all experiments, simplicity is quantified as the number of causes invoked in an explanation, with fewer causes corresponding to a simpler explanation. Experiment 1 confirms that all else being equal, both simpler and more probable explanations are preferred. Experiments 2 and 3 examine how explanations are evaluated when simplicity and probability compete. The data suggest that simpler explanations are assigned a higher prior probability, with the consequence that disproportionate probabilistic evidence is required before a complex explanation will be favored over a simpler alternative. Moreover, committing to a simple but unlikely explanation can lead to systematic overestimation of the prevalence of the cause invoked in the simple explanation. Finally, Experiment 4 finds that the preference for simpler explanations can be overcome when probability information unambiguously supports a complex explanation over a simpler alternative. Collectively, these findings suggest that simplicity is used as a basis for evaluating explanations and for assigning prior probabilities when unambiguous probability information is absent. More broadly, evaluating explanations may operate as a mechanism for generating estimates of subjective probability.
