Lost in the Rhythm: Effects of Rhythm on Subsequent Interpersonal Coordination

Music is a natural human expression present in all cultures, but the functions it serves are still debated. Previous research indicates that rhythm, an essential feature of music, can enhance coordination of movement and increase social bonding. However, the prolonged effects of rhythm have not yet been investigated. In this study, pairs of participants were exposed to one of three kinds of auditory stimuli (rhythmic, arrhythmic, or white‐noise) and subsequently engaged in five trials of a joint‐action task demanding interpersonal coordination. We show that when compared with the other two stimuli, exposure to the rhythmic beat reduced the practice effect in task performance. Analysis of the behavioral data suggests that this reduction results from more temporally coupled motor movements over successive trials and that shared exposure to rhythm facilitates interpersonal motor coupling, which in this context serves to impede the attainment of necessary dynamic coordination. We propose that rhythm has the potential to enhance interpersonal motor coupling, which might serve as a mechanism behind its facilitation of positive social attitudes.     

Good,Evil, and the Necessity of an Act

Kant asserts that the formula of the schools “nihil appetimus, nisi sub ratione boni” is undoubtedly certain when clearly expressed (KpV 177). Conversely, doubt reflects a failure clearly to express it. Once we comprehend the concepts of the formula, of the good (bonum) and of desire (appetitus), there is no doubting it. In recent times, the formula has fallen into doubt. If Kant is right, then this shows a lack of clarity with respect to the concepts the formula conjoins. I want to suggest that Kant is right: the formula of the schools is undoubtedly certain. I first explain in Kant’s own terms why there is no such thing as doubting the formula. Then I approach it from a different angle, provided by what I take to be the unclarity that affects current thought on the topic.     

Can self-compassion improve sleep quality via reduced rumination?

ABSTRACT

Poor sleep quality is highly prevalent in modern societies and can be associated with a multitude of problems for individuals and organizations, and also for society at large. Thus, there is a demand for efficient treatments. We suggest that short self-compassion interventions will improve sleep quality via reducing ruminative thoughts, a key variable associated with poor sleep quality. We ran three studies to test this hypothesis. In Study 1 (correlational data), a positive relationship between self-compassion and sleep quality emerged in students’ self-reports. This effect was mediated by rumination. In Study 2, students in two different self-compassion intervention conditions reported higher sleep quality compared to a control condition. Again, rumination mediated this effect. In Study 3, patients with major depressive disorder reported a significant increase in sleep quality and a significant decrease of ruminative thoughts after one week in a daily self-compassion intervention (compared to patients in a control condition). Limitations and implications for future research, such as the need of placebo control groups, objective sleep quality measures, and person–intervention fit designs are discussed.     

Muscle Dysmorphia Research Neglects DSM-5 Diagnostic Criteria

This systematic review aimed to collect, evaluate, and synthesize the research on muscle dysmorphia (MD) post official recognition as a specifier for body dysmorphic disorder (BDD) in the DSM-5, and provide recommendations for future research. Literature searches were conducted in four databases to see if inclusion criteria were met. Results revealed 33 studies meeting inclusion criteria, none of which utilized DSM-5 criteria for MD or acknowledged the criterion in their research. Few studies acknowledged the association between MD and BDD, and the methodological quality of recent MD research was considered low due to a lack of clinical samples, measurements not using validated cutoff scores, and the research designs. In conclusion, future MD research is encouraged to utilize DSM-5 diagnostic criteria to better inform clinical practice and significantly improve the methodological quality. As such, more effective treatment options may be developed, reducing the risk of health-harming consequences in these individuals.     

Buffering negative effects of immigration on cognitive,social, and educational development: A multinational meta-analysis of child and adolescent prevention programmes

Growing up in migrant families is a well-known distal risk factor related to poorer outcomes in child and adolescent health, academic, socioemotional and behavioural development. This article reviews the effects of various prevention measures such as early education programmes, cognitive and language training or parent and teacher training on child and adolescent developmental outcomes in immigration samples. Using several comprehensive literature searches, we found 138 research reports with 141 studies and 175 comparisons on preventing negative effects of immigration. Overall, programmes yielded an effect size of d = 0.26 at post-test using the random effect model. These effects decreased over time while still differing significantly from zero. A cross-tabulation of prevention approach/programme type by different outcome domains revealed several important results such as high effects of child cognitive and language training programmes on child academic and language outcomes and relatively low effects of all programmes on child socioemotional outcomes. In addition, individualised and culturally tailored programmes seems to be more effective. However, generalised effects on more distal educational outcomes (e.g., school degrees) were generally weak. Hence, it remains questionable whether individual psychosocial and educational programmes are able to counterbalance the multifaceted risks of immigration.     

What good leaders actually do: micro-level leadership behaviour,leader evaluations,and team decision quality

We supplement broad definitions of leadership behaviour with the concept of micro-level leadership behaviour, leaders’ verbal and non-verbal visible conduct and interaction. For the context of team decision-making, we identify two potentially beneficial micro-level leadership behaviours, question asking and behavioural mimicry. Specifically, we propose that under conditions of informational complexity and unshared information, participative leadership is most appropriate for team decision-making, that its effects are mediated by inquiring and empathy, and that question asking and mimicry are the behavioural micro-level manifestations of inquiring and empathy. We thus hypothesize that the effect of participative leadership on team decision quality and leader evaluation is mediated by question asking and mimicry. We conduct a laboratory experiment with student teams working on a hidden profile decision-making task and measure question asking through behavioural coding and mimicry with motion sensors. Results show that the effect of participative leadership on decision quality is mediated by question asking, and that the effect of participative leadership on leader evaluation as transformational is mediated by leaders’ behavioural mimicry and question asking. Under control of these micro-level behaviours, team decision quality and leader evaluations were unrelated.     

Effects of ego-depletion on choice behaviour in a multi-attribute decision task

When a choice has to be made between two options and decision-relevant information about the options is completely available, the Take-The-Best (TTB) heuristic only considers the most important information that discriminates between the options and bases its choice on it. Choices in line with TTB thus allow a decision maker to save time and effort, and they may become more likely therefore under conditions of limited self-control strength (ego-depletion). Ego-depletion was manipulated prior to making a series of choices in a multi-attribute decision task. Choices could have been in line with either TTB or more effortful compensatory decision strategies. As predicted, compared with non-depleted participants, ego-depleted participants were more likely to make TTB-consistent choices.     

Perceptions of the Targets and Sources of COVID-19 Threat are Structured by Group Memberships and Responses are Influenced by Identification with Humankind

The purpose of this study was to investigate which social groups are perceived as a threat target and which are perceived as a threat source during the COVID-19 outbreak. In a German sample (N = 1454) we examined perceptions of social groups ranging from those that are psychologically close and smaller (family, friends, neighbors) to those that are more distal and larger (people living in Germany, humankind). We hypothesized that psychologically closer groups would be perceived as less affected by COVID-19 as well as less threatening than more psychologically distal groups. Based on social identity theorizing, we also hypothesized that stronger identification with humankind would change these patterns. Furthermore, we explored how these threat perceptions relate to adherence to COVID-19 health guidelines. In line with our hypotheses, latent random-slope modelling revealed that psychologically distal and larger groups were perceived as more affected by COVID-19 and as more threatening than psychologically closer and smaller groups. Including identification with humankind as a predictor into the threat target model resulted in a steeper increase in threat target perception patterns, whereas identification with humankind did not predict differences in threat source perceptions. Additionally, an increase in threat source perceptions across social groups was associated with more adherence to health guidelines, whereas an increase in threat target perceptions was not. We fully replicated these findings in a subgroup from the original sample (N = 989) four weeks later. We argue that societal recovery from this and other crises will be supported by an inclusive approach informed by a sense of our common identity as human beings.
