Sound improves diminished visual temporal sensitivity in schizophrenia

Visual temporal processing and multisensory integration (MSI) of sound and vision were examined in individuals with schizophrenia using a visual temporal order judgment (TOJ) task. Compared to a non-psychiatric control group, persons with schizophrenia were less sensitive judging the temporal order of two successively presented visual stimuli. However, their sensitivity to visual temporal order improved as in the control group when two accessory sounds were added (temporal ventriloquism). These findings indicate that individuals with schizophrenia have diminished sensitivity to visual temporal order, but no deficits in the integration of low-level auditory and visual information.     

Under the Spell of the Ring

Among orthodox reformed Christians in the Netherlands fierce debates have occurred on moral aspects of Christian life. This essay discusses three major controversial moral issues that are related to conceptions of sex, gender, and sexuality: divorce/remarriage, women’s ordination, and homosexuality. By analysing several contributions to debates on these issues, it proposes and explores a hypothesis that concerns the role of a particular understanding of marriage as characterized by a hermeneutical construct: a communal, deeply rooted and subconscious normative principle that drives our interpretations of texts and practices. This essay illustrates the problems of both the dominance of marriage within Christian communities and lived faith, as well as the modern, romantic aspects of this particular understanding of marriage.     

An Experimental Investigation of Election Promises

We analyze the effect of election promises on electoral behavior in a laboratory experiment. In the experiment, politicians can make nonbinding election promises about how to split an endowment between themselves and the group. We find that promises affect both voting and voter beliefs about how much the politician will contribute to the public fund. The relationship is inverted U‐shaped with decreasing credibility of higher promises. Contributions of politicians are correlated with their promises in a similar pattern. The election promises are generally credible unless particularly high. Politicians keep promises more often if a reelection is possible and if the politician came into power by vote rather than by random draw. Voters reward high contributions in the previous period and punish promise breaking even after controlling for the contribution in the previous period or voters' beliefs about future contributions. By controlling for voters' beliefs, we distinguish retrospective from prospective voting. Our results suggest that voters both use promises for prospective voting and retrospectively punish broken promises.     

Effectiveness of the ‘Hold me Tight’ Relationship Enhancement Program in a Self‐referred and a Clinician‐referred Sample: An Emotionally Focused Couples Therapy‐Based Approach

While evidence‐based couple therapies are available, only a minority of troubled couples seek help and they often do this too late. To reach more couples earlier, the couple relationship education (CRE) group program “Hold me Tight” (HmT) based on Emotionally Focused Couples Therapy (EFCT) was developed. This study is the first to examine the effectiveness of HmT. Using a three‐wave (waiting period, treatment, and follow‐up) within‐subject design, HmT was delivered to 79 self‐referred couples and 50 clinician‐referred couples. We applied a comprehensive outcome measure battery. Our main findings were that (1) self‐referred couples significantly improved during HmT on all measures, that is relationship satisfaction, security of partner‐bond, forgiveness, daily coordination, maintenance behavior, and psychological complaints, with a moderate‐to‐large mean effect size (d = .63), which was maintained (d = .57) during the 3.5 month follow‐up; (2) in clinician‐referred couples, who were vulnerable in terms of insecure attachment status and psychopathology, the improvement during HmT was moderate (d = .42), but this was reduced during the 3.5‐month follow‐up to a small effect (d = .22); (3) emotional functioning (typical HmT target) as well as behavioral functioning (typical Behavioral Couples Therapy‐based CRE target) improved during HmT; and (4) individual psychological complaints, although not specifically targeted, were reduced during HmT. These findings suggest that HmT is a promising intervention for enhancement of relationship functioning. Clinical implications are discussed.     

The Ingredients of Aristotle’s Theory of Fallacy

In chapter 8 of the Sophistical Refutations, Aristotle claims that his theory of fallacy is complete in the sense that there cannot be more fallacies than the ones he lists. In this article I try to explain how Aristotle could have justified this completeness claim by analysing how he conceptualizes fallacies (dialectical mistakes which do not appear so) and what conceptual ingredients play a role in his discussion of fallacies. If we take the format of dialectical discussions into account, we will see that there are only so many mistakes one can make which still do not appear to be mistakes. Aristotle’s actual list is almost identical to these apparent mistakes.     

Incidental image memorability

ABSTRACT

Recent studies using intentional memory tasks showed that images differ consistently in memorability. Here, we used a surprise recognition memory test. We asked how incidental encoding would affect the consistency and ranking of the memorability scores. If memorability is truly an intrinsic property of the image, one should not expect large differences between incidental and intentional conditions. On the other hand, participants might process images differently when not anticipating a memory test, yielding different results. The study list of our incidental memory task was identical to our previous, intentional study. Participants were to watch the images of this list carefully as they appeared on the screen one by one (free viewing); supposedly for a study about eye movements. Afterwards, a surprise recognition memory test was administered. Despite the free viewing instructions during the study phase, the resulting incidental image memorability scores still showed high levels of consistency across participants. In addition, the overlap between the incidental and intentional memorability ranking was large. These results provide further support for the idea of memorability as an intrinsic image property and add to its ecological validity, as people rarely memorise images intentionally.     

Innovativeness and initiative as mediators between achievement orientation and venture performance

A central question in entrepreneurship research is how to predict venture performance. In prior research, psychological characteristics of the entrepreneur and entrepreneurial behaviours have been more or less found to be able to distinguish between successful and unsuccessful entrepreneurs. The aim in this study was to extend earlier research and to test a model in which innovativeness and initiative are mediators between achievement orientation (including the psychological characteristics: self-efficacy, higher order need strength, need achievement, and internal locus of control) and venture performance. Data from 201 entrepreneurs were analysed with structural equation modelling to test the mediation model. The results suggest that innovativeness is a mediator between achievement orientation and venture performance, whereas initiative could not be confirmed as a mediator.     

Personality profiling of South African rugby union players

This study aimed to investigate whether differences exist in the personality profiles of professional and semi-professional rugby union players. Participants were 73 male rugby players, 52 professional players and 21 semi-professional players. All participants completed the NEO Five-Factor Personality Inventory (NEO-FFI) as part of the WebNeuro Sport online assessment. An independent sample t-test showed a statistically significant difference in neuroticism between the professional and semi-professional players. The magnitude-based inference method confirmed the results of the independent sample t-test with a moderate effect. The potential practical value of these findings is that the Neuroticism scale of the Big Five personality dimensions can be used as a screening tool for indicating which players a team would want to recruit and invest time and money in since these players will most likely be capable of progressing to the top level in their sport.     

Models of Educational Career With and Without IQ Measurements

Path models of educational careers do not usually contain information about phenotypical intelligence levels. This may lead to an overestimation of direct environmental effects such as the educational level of the parents on the education attained by the children. This phenomenon was investigated on the basis of data describing educational level, occupational status, and intelligence measurements of 2,847 father-son pairs. The IQ was determined during testing for military service by means of a shortened version of Raven's Progressive Matrices Test. The results were twofold. When the son's IQ was included in the model describing his educational career, environmental effects due to the influence of the father were reduced. Adding the father's IQ to the model, however, did not affect the path coefficients of the variables that were predicted to be relevant for the son's education.
