Therapy for couples after an affair: A randomized-controlled trial

To examine the efficacy of a couples treatment approach for promoting recovery from a recently disclosed affair, 89 couples that disclosed an affair by one of the partners in the past 6 months were randomly assigned to treatment (n = 46) or to a control group that waited about 3 months for treatment (n = 43). The couples completed self-report measures (Beck Depression Inventory, Impact of Event Scale-Revised, Partnership Questionnaire) at pre- and post-treatment. Since about half of the couples dropped out for various reasons (e.g., ongoing affair, separation), we used multiple imputations to handle the missing data problem. We analyzed the dyadic data with hierarchical linear modeling in a two-level model. Significant improvements on scores of anxiety corresponded with large effect sizes for both partners. Yet significant improvements on depression scores were only found for the unfaithful partner with moderate effect size. Results suggest that the treatment can improve individual complaints, but not relationship satisfaction in a sufficient amount for both partners. Hence, future research should address how this intervention could encourage couples to maintain therapy, and how they might achieve more and sustained improvement in relationship satisfaction.     

Recall termination in free recall

Although much is known about the dynamics of memory search in the free recall task, relatively little is known about the factors related to recall termination. Reanalyzing individual trial data from 14 prior studies (1,079 participants in 28,015 trials) and defining termination as occurring when a final response is followed by a long nonresponse interval, we observed that termination probability increased throughout the recall period and that retrieval was more likely to terminate following an error than following a correct response. Among errors, termination probability was higher following prior-list intrusions and repetitions than following extralist intrusions. To verify that this pattern of results can be seen in a single study, we report a new experiment in which 80 participants contributed recall data from a total of 9,122 trials. This experiment replicated the pattern observed in the aggregate analysis of the prior studies.     

Morningness-eveningness and sleep habits among adolescents: age and gender differences

Previous research has indicated the need to use large samples in different cultural contexts in order to clarify age and gender differences on morningness-eveningness and sleep habits. The goal of our research was to study the relationship between morningness-eveningness and sleep habits in a large sample of 2,649 adolescents between 12 and 16 years. The Morningness- Eveningness Scale for Children and an adaptation of the School Sleep Habits Survey measures were used. Results indicated a greater tendency toward eveningness with age and higher eveningness in 13- and 14-year-old girls. Older adolescents claimed later rising time on weekends, later bedtime and shorter sleep length, and greater social jetlag, weekend rise time delay, and weekend bedtime delay. Girls reported earlier rising time on weekdays, later rising time on weekends, longer sleep length on weekends, and greater social jetlag and weekend rising time delay. Lastly, evening oriented adolescents claimed later rising time and bedtime, shorter sleep length on weekdays but longer sleep duration on weekends, and greater social jetlag, weekend rising time delay, and weekend bedtime delay.     

Sex differences of salivary cortisol secretion in patients with major depression

Depression is associated with increased cortisol secretion and occurs more often in women than in men. Thus, it has been hypothesized that differences in cortisol secretion might, in part, be responsible for the greater risk of developing depression in women. However, only few studies have examined sex differences in baseline cortisol secretion in depressed patients and healthy controls. We examined sex effects on cortisol secretion in 52 medication-free patients with major depression (37 women, 15 men, mean ± SD age 35 ± 11 years, Hamilton Depression Scale mean score 27 ± 5) and 50 healthy age- and sex-matched control subjects. Salivary cortisol concentrations were measured at 8:00, 12:00, 16:00, and 22:00 h. Repeated measures analysis of covariance revealed a group × sex interaction (p = 0.05). Post hoc tests revealed higher cortisol concentrations in depressed compared to healthy men [F(1;29) = 7.5, p = 0.01]. No differences were found between depressed and non-depressed women. Our results do not support the hypothesis that differences in cortisol secretion between depressed and non-depressed subjects are more pronounced in women than in men. Study characteristics and methods as well as sex-specific confounding variables such as menstrual cycle, menopause and the use of oral contraceptives may account for inconclusive results across studies.

Beauty: Neglected,but alive and kicking

This article is a commentary on ‘Ten years of a model of aesthetic appreciation and aesthetic judgments: The aesthetic episode – developments and challenges in empirical aesthetics’ (Leder & Nadal, 2014, this issue). It focuses on the importance of beauty in aesthetic appreciation and aesthetic judgments. Beauty is considered as a formal inherent property of visual stimuli that has the potential to elicit visual pleasure by direct sensory stimulation. It is argued that any comprehensive model of aesthetic experience must account fully for cognitive aspects of aesthetics (cultural, conceptual, psychological, and individual factors) as well as intrinsic properties of beautiful visual stimuli and how they relate to basic mechanisms of visual perception, which are universal among humans.     

Measuring Four Perspectives of Justice Sensitivity With Two Items Each

People differ systematically in their vulnerability to injustice. We present two-item scales for the efficient measurement of justice sensitivity from 4 perspectives (victim, observer, beneficiary, perpetrator). In Study 1 using a quota-based sample of German adults, a latent state–trait analysis revealed the factorial validity and high reliabilities of the scales. In Study 2 employing a large random sample, we tested for measurement invariance of the items within the context of our short 2-item scales compared to the original 10-item scales. Multigroup confirmatory factor analyses confirmed that the validity of the indicators and the internal structure of the assessed constructs did not change across item contexts. In both studies, correlations with personality dimensions and life satisfaction provide evidence for the validity of our scales. With the presented instrument, future research can extend scientific knowledge regarding the role of individual differences in reactions to injustice for the explanation of well-being and physical health.     

From Games to Truth Functions: A Generalization of Giles’s Game

Motivated by aspects of reasoning in theories of physics, Robin Giles defined a characterization of infinite valued ?ukasiewicz logic in terms of a game that combines Lorenzen-style dialogue rules for logical connectives with a scheme for betting on results of dispersive experiments for evaluating atomic propositions. We analyze this game and provide conditions on payoff functions that allow us to extract many-valued truth functions from dialogue rules of a quite general form. Besides finite and infinite valued ?ukasiewicz logics, also Meyer and Slaney’s Abelian logic and Cancellative Hoop Logic turn out to be characterizable in this manner.     

Analyzing distributional properties of interference effects across modalities: chances and challenges

In research investigating Stroop or Simon effects, data are typically analyzed at the level of mean response time (RT), with results showing faster responses for compatible than for incompatible trials. However, this analysis provides only limited information as it glosses over the shape of the RT distributions and how they may differ across tasks and experimental conditions. These limitations have encouraged the analysis of RT distributions using delta plots. In the present review, we aim to bring together research on distributional properties of auditory and visual interference effects. Extending previous reviews on distributional properties of the Simon effect, we additionally review studies reporting distributional analyses of Stroop effects. We show that distributional analyses of sequential effects (i.e., taking into account congruency of the previous trial) capture important similarities and differences of interference effects across tasks (Simon, Stroop) as well as across sensory modalities, despite some challenges associated to this approach.
