The role of interpersonal movement synchronisation in empathic functions: Insights from Tango Argentino and Capoeira

Although evidence points to a role for kinesthetic empathy (i.e. spontaneous interpersonal movement imitation and synchronisation) in social interaction, its relationship with emotional and cognitive aspects of empathy is unknown. We compared empathy in Tango and Capoeira experts, which crucially depend on ongoing, mutual interpersonal synchronisation, with empathy in practitioners of Salsa and Breakdance, respectively, which demand less interpersonal synchronisation but are comparable concerning movements and setting. Kinesthetic empathy was increased in the Tango and Capoeira groups. Although no group differences in other aspects of empathy were detected, kinesthetic empathy correlated with emotional and cognitive empathy. Taken together, trait kinesthetic empathy varies in the general population, and appears increased in synchronisation experts.     

Escalation behavior in domains related and unrelated to decision makers' academic background

Based on Staw and Ross's (1987) analysis of escalation behavior it was hypothesized that (a) those who are involved with projects related to their academic background will tend to persist in a losing course of action and to judge the situation as reversible more than those who have to make decisions in areas unrelated to their specialty; (b) providing information that the loss is irreversible will decrease the tendency to invest additional resources. A secondary goal of the study was to examine whether there would be any difference in sunk cost decisions when the resource invested is financial as compared to time. Using a 2 × 2 × 2 factorial design, a total of 296 students were given eight different scenarios in which relatedness of decision subject-matter to academic background, reversibility of the situation, and type of resources (time or money) were the independent variables, and commitment to a course of action was the dependent variable. The results confirmed the hypotheses. No significant main effect for type of resources (time vs. money) was found. Theoretical and practical implications of the results are discussed.The authors thank Dr. Michael Hoffman for his valuable contribution in preparing this paper.     

A VIROCENTRIC PERSPECTIVE ON EVIL

Abstract. The coronavirus pandemic has stirred interest in viruses. This has been accompanied by a proliferation of popular works trying to explain how viruses fit into the Christian worldview. In an anthropocentric perspective, viruses are easily regarded as malicious entities. This article, however, shows that a proper understanding of the biology of viruses actually adds another level of complexity to our perception of good and evil. Interestingly, this additional layer of complexity might help us solve some of the most urgent difficulties in the discussion about good and evil, if we recognize the subjective nature of what we call natural evil. We need to be more nuanced not merely in our theological discussion about good and evil, but also in the way we talk about viruses.     

Understanding linear and exponential growth: Searching for the roots in 6- to 9-year-olds

Previous studies have suggested that children as young as 9 years old have developed an understanding of non-linear growth processes prior to formal education. The present experiment aimed at investigating this competency in even younger samples (i.e., in kindergartners, first, and third graders, ages 6, 7 and 9, respectively). Children (N = 90) solved non-verbal inductive reasoning tasks by forecasting linear and exponential growth. While children of all ages forecasted linear growth adequately, exponential growth was also estimated remarkably well. Surprisingly, kindergartners and third graders showed similar high achievement concerning the magnitude and curve shape of forecasts, whereas first graders performed significantly worse. We concluded that primary knowledge of both linearity and non-linearity exists even in kindergartners. However, children's understanding is quite fragile, as their performance was strongly affected by task sequence: Children underestimated exponential growth when the previous task required a forecast of linear growth, and overestimated linear growth when the previous task required forecasting of exponential growth.     

Forecasting exponential growth and exponential decline: similarities and differences

Previous research has demonstrated adults' difficulties with explicitly forecasting exponential processes. Exponential growth is usually grossly underestimated, whereas exponential decline is forecast more accurately. By contrast, the present study examined implicit knowledge about exponential processes and how it is affected by function type (growth versus decline) in samples of 7-, 10-, 14-year-olds, and adults (N=80). Different indicators of the quality of forecasts were investigated. As opposed to previous findings, participants of all age groups estimated exponential decline less adequately than exponential growth. This effect could be attributed mainly to the fact that, in relation to fitted exponential functions, the starting value, or intercept, of the function was approximated well for exponential growth but badly with regard to exponential decline. The accuracy of the non-linear component in forecast functions barely differed between function types within the same age group. Furthermore, even 7-year-olds appeared to have a preliminary understanding of exponential processes, while both intercepts and exponents of forecasts became more accurate with age. Theoretical and practical implications are discussed.     

Sounds change four-dot masking

The temporal occurrence of a flash can be shifted towards a slightly offset sound (temporal ventriloquism). Here we examined whether four-dot masking is affected by this phenomenon. In Experiment 1, we demonstrate that there is release from four-dot masking if two sounds - one before the target and one after the mask - are presented at ∼100 ms intervals rather than at ∼0 ms intervals or a silent condition. In Experiment 2, we show that the release from masking originates from an alerting effect of the first sound, and a temporal ventriloquist effect from the first and second sounds that lengthened the perceived interval between target and mask, thereby leaving more time for the target to consolidate. Results thus show that sounds penetrate the visual system at more than one level.     

Becoming More Conscientious or More Open to Experience? Effects of a Two-Week Smartphone-Based Intervention for Personality Change

Research indicates that it might be possible to change personality traits through intervention, but this clinical research has primarily focused on changing neuroticism. To date, there are no established, proven techniques for changing other domains of personality, such as conscientiousness and openness. This research examined the effects of a two-week smartphone-based intervention to either change one facet of conscientiousness (i.e. self-discipline) or one facet of openness to experience (i.e. openness to action). Two intervention studies (total N = 255) with two active intervention groups for mutual comparisons were conducted. Results of self-reports and observer reports showed that people who wanted to become more self-disciplined were less self-disciplined at pretest. Similarly, people who wanted to become more open to action were less open to action at pretest. The results showed that people who chose the self-discipline intervention showed greater increases in self-discipline, and people who chose the openness to action intervention showed greater increases in openness to action compared with the other group. Changes were maintained until follow-up two and six weeks after the end of the intervention. Future work is needed to examine whether these personality changes are enduring or reflect temporary accentuation as a result of participation in the intervention. © 2020 European Association of Personality Psychology     

Perception of intersensory synchrony: A tutorial review

For most multisensory events, observers perceive synchrony among the various senses (vision, audition, touch), despite the naturally occurring lags in arrival and processing times of the different information streams. A substantial amount of research has examined how the brain accomplishes this. In the present article, we review several key issues about intersensory timing, and we identify four mechanisms of how intersensory lags might be dealt with: by ignoring lags up to some point (a wide window of temporal integration), by compensating for predictable variability, by adjusting the point of perceived synchrony on the longer term, and by shifting one stream directly toward the other.     

Atypicality and the two fundamental dimensions: Applying the negativity effect on warmth to group perception

The person perception literature has shown that negative information on warmth influences impression formation more than other kinds of information. In the present paper, we argue for the usefulness of using the knowledge accumulated on the negativity effect on warmth when studying how members of a group who are disconfirming the group stereotype are perceived. We show that negative divergent information on warmth is perceived as more surprising because it appears to be more discrepant than positive divergent information on warmth or than competence information. We also show how stereotype holders protect their stereotype by rating the surprising incoherent information as atypical. Results are discussed in terms of the necessity to apply our knowledge of the two fundamental dimensions of social perception and their properties to typicality ratings and, beyond them, to stereotype change research.

The bilingual lexicon: Modality effects in processing

In this article the effects of modality on the processing in the bilingual lexicon will be explored. Therefore, two parallel repetition priming experiments were conducted, an auditory and a visual one. The subjects were Dutch-English bilinguals. They had to perform a lexical decision task. There were two types of stimuli: cognates and noncognates. The results indicated that there are no processing differences between the auditory and the visual modalities. Furthermore, in both experiments interlingual repetition priming was found for both cognates and noncognates. The implications of these results for the influence of the factor proficiency level are discussed.
