Social spatial cognition: social distance dynamics as an identifier of social interactions

We suggest that socio-spatial behavior, which is an interaction between social and spatial cognition, can be viewed as a set of excursions that originate and end in close proximity to another individual(s). We present an extension of earlier studies that perceived spatial behavior in individual animals as a series of excursions originating from a particular location. We measured here the momentary distance between two individuals (social distance) to differentiate among eight possible types of social excursion originating in a state of proximity between excursion-participants. The defined excursion types are based on whether or not the excursion initiator also concludes the excursion, whether or not the excursion starts and ends at the same location, and the dynamics of the distance between excursion participants. We validated this approach to socio-spatial behavior as a set of excursions using it to analyze the behavior of the two sexes in rodents, of normal vs. stereotyped rats, as well as of different rodent species. Each of these groups displays a prevalent excursion type that reflects a distinct social dynamics. Our approach offers a useful and comprehensive tool for studying socio-spatial cognition, and can also be applied to distinguish among different social situations in rodents and other animals.

     

Is Lying Bound to Commitment? Empirically Investigating Deceptive Presuppositions,Implicatures, and Actions

Lying is an important moral phenomenon that most people are affected by on a daily basis—be it in personal relationships, in political debates, or in the form of fake news. Nevertheless, surprisingly little is known about what actually constitutes a lie. According to the traditional definition of lying, a person lies if they explicitly express something they believe to be false. Consequently, it is often assumed that people cannot lie by more indirectly communicating believed-false claims, for instance by merely conversationally implicating them. In this paper, we subject this claim to an empirical test. In a preregistered study of 300 participants, we investigate how people judge cases of implicit deceptions that would usually be excluded by the traditional definition of lying (i.e., conversational implicatures, presuppositions, and nonverbal actions). Our results show that people do in fact consider it possible to lie by indirect means, suggesting that people have a broader concept of lying than is usually assumed. Moreover, our findings indicate that lie judgments are closely tied to the extent to which agents are perceived as having committed themselves to the believed-false claims they have communicated. We discuss the implications of our results for the traditional definition of lying and propose a new commitment-based definition of lying that can account for the findings of our experiment.

When leader–member exchange differentiation improves work group functioning: The combined roles of differentiation bases and reward interdependence

Drawing on social hierarchy theory, we develop a contingency model of leader–member exchange (LMX) differentiation in which LMX differentiation is positively and negatively related to group cooperation and group social undermining, respectively, when it is based on the group members’ performance, but the relations are reversed (i.e., negative and positive, respectively) when it stems from a leader's personal liking of the members. In addition, we propose that the moderating effects of the performance and personal liking bases of LMX differentiation are magnified by the levels of reward interdependence. Specifically, under a high (vs. low) level of reward interdependence, LMX differentiation based on performance more strongly relates to high group cooperation and low group social undermining, whereas LMX differentiation with a personal liking basis is more likely to decrease group cooperation and increase group social undermining. Group cooperation and social undermining are then hypothesized to convey the three‐way interactive effects of LMX differentiation, its two bases, and reward interdependence on subsequent group performance. Analyses of data from 328 sales groups of a large retailer support the core part of our contingency model of LMX differentiation.     

A Taxometric Analysis of Experiential Avoidance

Experiential avoidance, a trait-like construct referring to the tendency to rigidly avoid or change unpleasant internal experiences stemming from an unwillingness to experience them, is believed to contribute to the development and maintenance of various forms of psychopathology. Despite significant research on this construct, it remains unclear whether experiential avoidance is dimensional or categorical at the latent level. The current study examined the latent structure of experiential avoidance using three taxometric analytic approaches (MAXimum Eigenvalue, Mean Above Minus Below A Curve, Latent-Mode Factor Analysis) applied to data from two independent samples and using three widely used measures of experiential avoidance. The first sample (n = 922) completed the Multidimensional Experiential Avoidance Questionnaire (Gámez, Chmielewski, Kotov, Ruggero, & Watson, 2011), while the second sample (n = 615) completed the Brief Experiential Avoidance Questionnaire (Gámez et al., 2014) and Acceptance and Action Questionnaire-II (Bond et al., 2011). Across both samples and all three measures, experiential avoidance exhibited a dimensional structure. The clinical and research implications of this finding for experiential avoidance are discussed.     

Investigating the Effects of Media Consumption on Attitudes Toward Police Legitimacy

Prior investigations have examined both traditional media (e.g., television news) and entertainment media (e.g., crime-related shows) on policing-related outcomes; however, less is known how contemporary forms of media, such as the Internet and social media, may affect policing-related outcomes. Using a sample of young adults, the current study examines the effect of multiple types of media consumption (traditional, entertainment, the Internet, and social media) on attitudes toward police legitimacy. Findings reveal that respondents who read news online are more likely to have negative attitudes toward police legitimacy. However, when individual differences are controlled for, the effect of reading news online is weakened and using social media becomes marginally significant. Further, the impact of media consumption on attitudes toward police legitimacy varies by key audience characteristics.     

Searching for two categories of target in dynamic visual displays impairs monitoring ability

Target onsets in dynamically changing displays can be predicted when contingencies exist between different stimulus states over time. In the present study, we examined predictive monitoring when participants searched dynamically changing displays of numbers and colored squares for a color target, a number target, or both. Stimuli were presented in both contiguous and discrete spatial configurations. Response time (RT) and accuracy were recorded, and evidence of predictive monitoring was assessed via first fixations and refixations of target‐predictive stimuli. RTs to target onsets and evidence of predictive monitoring were reduced in dual‐target, relative to single‐target, conditions. Further, predictive monitoring did not speed RTs but was influenced by display configuration. In particular, discrete displays impaired monitoring for number targets in the dual‐target condition. Implications exist for real‐world visual tasks involving multiple target categories and for visual display design.     

On "risk" and reward: investigating state anhedonia in psychometrically defined schizotypy and schizophrenia

Anhedonia, defined as dysfunction in the experience of pleasant emotions, is a hallmark symptom of the schizophrenia spectrum. Of interest, it is well documented that patients with schizophrenia, at least as a group, do not show reductions in their state experience of pleasant stimuli. However, there is emerging evidence to suggest that individuals with schizotypy--defined as the personality organization reflecting the latent vulnerability for schizophrenia--do show these state deficits. This is paradoxical in that schizophrenia reflects a more pathological state in virtually every conceivable domain as compared with schizotypy. The present study examined self-reported affective reactions to neutral-, bad-, and good-valenced stimuli in individuals with psychometrically defined schizotypy and schizophrenia. Two separate control groups were also included, comprising psychometrically defined controls and stable outpatients with affective disorders. With no exceptions, the schizotypy group reported significantly less pleasant affect for each of the three conditions than each of the other groups. Conversely, the schizophrenia group did not statistically differ from the control groups for any of the conditions. Within both the schizotypy and schizophrenia groups, severity of negative symptoms/traits was associated with less pleasant report. We found that individuals with prominent negative symptoms and traits from the schizophrenia and schizotypy groups resembled each other in terms of state anhedonia. The present findings did not appear to reflect comorbid depression or anxiety. Our discussion centers on this apparent paradox in the schizophrenia spectrum--that individuals with schizotypy exhibit state anhedonia, whereas patients with schizophrenia do not.     

Religiosity and Social Support: Implications for the Health-Related Quality of Life of African American Hemodialysis Patients

The purpose of this study was to determine whether sociocultural differences have any effect on the health-related quality of life among African American hemodialysis patients. This study examined relationships between religiosity, social support, and the health-related quality of life of African American hemodialysis patients. Four hemodialysis units were selected for the study. The study population consisted of 176 African American hemodialysis patients who had been receiving hemodialysis treatments for at least 1 month. The religiosity variable was measured by the Measure of Religious Involvement. Social Support was measured by the Medical Outcomes Study Social Support Survey, and health-related quality of life was measured by the Medical Outcomes Study 36 Short Form Health Survey (SF-36v2). The investigators found that social support contributed to the emotional and physical health of African American hemodialysis patients in the sample, whereas religiosity was inversely related to the physical health of these patients.
