Negative intergroup contact makes group memberships salient: explaining why intergroup conflict endures

Drawing from the intergroup contact model and self-categorization theory, the authors advanced the novel hypothesis of a valence-salience effect, whereby negative contact causes higher category salience than positive contact. As predicted, in a laboratory experiment of interethnic contact, White Australians (N = 49) made more frequent and earlier reference to ethnicity when describing their ethnic contact partner if she had displayed negative (vs. positive, neutral) nonverbal behavior. In a two-wave experimental study of retrieved intergenerational contact, American young adults (N = 240) reported age to be more salient during negative (vs. positive) contact and negative contact predicted increased episodic and chronic category salience over time. Some evidence for the reverse salience-valence effect was also found. Because category salience facilitates contact generalization, these results suggest that intergroup contact is potentially biased toward worsening intergroup relations; further implications for theory and policy making are discussed.     

‘Eppur si move’: The Association Between Electrophysiological and Psychophysical Signatures of Perceived Movement Illusions

Vibration applied to muscle tendons induces an illusory perception of movement by activating spindle receptors and Ia afferent fibers. While neural structures supporting such illusions are quite defined, functional and psychophysical correlates of their perception have not been deeply investigated. The authors aimed at exploring subjective perception of illusory movements thanks to a repeated-stimulation multimodal approach. The integrated analysis of electroencephalography, source data (standardized low-resolution brain electromagnetic tomography–sLORETA), and psychophysical evaluation pointed at the activation of a frontoparietal sensorimotor network, with prefrontal-medial regions mainly involved in supporting the awareness for illusory movements. Further, illusions showed consistency in terms of presence, vividness, and duration. Finally, superior parietal structures seemed to play an important role in self-attribution of agency and ownership during such experiences.     

Shrinkage estimation of the three-parameter logistic model

The three-parameter logistic model is widely used to model the responses to a proficiency test when the examinees can guess the correct response, as is the case for multiple-choice items. However, the weak identifiability of the parameters of the model results in large variability of the estimates and in convergence difficulties in the numerical maximization of the likelihood function. To overcome these issues, in this paper we explore various shrinkage estimation methods, following two main approaches. First, a ridge-type penalty on the guessing parameters is introduced in the likelihood function. The tuning parameter is then selected through various approaches: cross-validation, information criteria or using an empirical Bayes method. The second approach explored is based on the methodology developed to reduce the bias of the maximum likelihood estimator through an adjusted score equation. The performance of the methods is investigated through simulation studies and a real data example.     

How Powers Emerge from Relations

I shall explore in this article the metaphysical possibility of powers’ strongly emerging from relations. After having provided a definition of emergent powers that is also based on the distinction between the possession and the activation of a power, I shall introduce different sorts of Relations that Ground Emergence, both external and internal. Later on, I shall discuss some examples of powers that are grounded on their instantiation. Finally, I shall examine the consequences of accepting such relations within a physicalistic ontology and I shall defend them against two objections based on the notion of bruteness.     

Past and future of near-infrared spectroscopy in studies of emotion and social neuroscience

Near-infrared spectroscopy (NIRS) enables the non-invasive measurement of spatiotemporal characteristics of brain function, which has received increasing attention during the last years. This new birth of interest is attributable to unique characteristics of the NIRS technique, which may be summarised in certain technical advantages: its experimental and ecological validity and the extension of application to clinical samples. This paper presents the main applications of the NIRS technique that measures changes in brain activation to study emotions and social neuroscience field. In the first part of this paper, we discuss the basic principles, strengths, and limitations of NIRS for the study of principal emotional functions. In the second part, we focus on the actual applications of NIRS in emotional and social research. In this regard, first, we consider some main topics of emotional contexts, such as visual (facial expression) and auditory cues recognition, and social neuroscience field. Second, we discuss the utility to apply NIRS simultaneously to other techniques (electroencephalography, Transcranial Magnetic Stimulation, and functional Magnetic Resonance Imaging) to improve the intrinsic power of such measures. Third, we consider the possible applications of NIRS devices to study specific emotion-related functions (such as connectivity and plasticity applications).     

The Italian Version of SCORE-15: Validation and Potential Use

SCORE-15 (Systemic Clinical Outcome and Routine Evaluation) is a 15-item questionnaire for completion by family members aged 12 years and older to assess outcomes in systemic therapy. This study aimed to investigate (a) the psychometric properties and the internal consistency reliability of the Italian version of SCORE-15, (b) clinical responsiveness, and (c) normative (Italian) criteria. Furthermore, (d) the study sought to evaluate the participants’ representation of both their family and their problems, analyzing open-ended questions included in the SCORE-15. Data were collected from two clinical centers for 208 families (n = 507). Results confirmed the three-factor structure (i.e., strengths, difficulties, and communication), a good internal consistency reliability, and indicated a cutoff threshold for the Italian version. Furthermore, results showed that SCORE-15 is a good instrument for clinical responsiveness and that it can be used to explore the way in which family members describe their families and problems. Overall, SCORE-15 is a brief, psychometrically robust family assessment instrument that may be used for both researchers and practitioners in several domains of clinical and social psychology.     

The temporal stability of the effects induced by the cued reaction time task

The temporal stability of the effects induced by the Cued Reaction Time Task (CRTT) on the orienting of attention was assessed across four weekly sessions. Benefits, costs, and validity effects were computed for each session, and the correlation coefficients between each session were calculated (interindividual stability index). Intraindividual stability indices, the percentage of individuals showing both costs and benefits or the validity effect, were also calculated. The results (based on 41 participants) show a low stability for the effects in which the neutral trials were involved (benefits and costs) but an acceptable reliability for the validity effect, especially when evaluated using the intraindividual index. To maximize the reliability of the data collected using the CRTT, the validity effect seems to be a better probe of spatial orienting of attention.     

Age-related changes in implicit emotion processing

The aim of the present study was to compare the performance of older and younger adults on an emotional priming task. Moreover, a nonemotional priming paradigm was used as a control task to disentangle age-related changes due to emotional processing difficulties from modifications due to a decline of executive inhibitory control abilities. Twenty-two young and 22 older healthy participants completed an emotional priming task and a nonemotional priming task. In the older adult group, reaction times in the emotional priming paradigm were not influenced by any of the prime conditions, whereas both groups exhibited similar facilitation effects induced by the congruent prime in the nonemotional task. The selective lack of an emotional priming effect in older adults shown in this preliminary report suggests that aging-induced changes in the ability to recognize emotions implicitly are directly dependent on emotional processing difficulties and not due to a general age-related modification of cognitive processes.     

Work addiction and presenteeism: The buffering role of managerial support

The current study examined the mediating effect of presenteeism and moderating effect of managerial support in the relation between workaholism and work–family conflict. A sample of 1065 white‐collar employees from an Italian company filled in an online survey and hypotheses were tested using a bootstrapping procedure. Results showed that presenteeism mediated the association between workaholism and work–family conflict. Moreover, the mediating effect of presenteeism was moderated by managerial support: for employees reporting lower levels of support workaholism was stronger related to presenteeism than for those experiencing higher support. Presenteeism, in turn, was related to greater levels of work–family conflict. The present study sheds light into the protective role played by managerial support in preventing workaholic employees from forcing themselves to attend work also when feeling sick. Accordingly, early intervention aimed at buffering the negative association between workaholism and work–family conflict should focus on training managers to develop supportive leadership skills.     

Can We Identify with a Nation Low in Morality? The Heavy Weight of (Im)Morality in International Comparison

Research has shown that the perceived morality of the ingroup is a primary source of group pride and ingroup identification. The present research examined whether this is true even when a group has a poor reputation for morality in terms of dishonesty and corruption, such as in the case of Italians. To address this issue, two studies analyzed the role of the three fundamental dimensions of social judgment—morality, competence, and sociability—in predicting Italians’ identification with their nation when the salience of social comparison and the status of the comparison outgroup were varied. Findings showed that perceived morality predicted ingroup identification when participants did not engage in social comparison. Under salient social comparison, individuals based group identification on other dimensions: Perceived sociability was the main predictor of identification when respondents compared with a higher status outgroup (Germans; Study 1; N = 109), whereas perceived competence was the main predictor of identification when participants compared with a lower status outgroup (Romanians; Study 2; N = 121). Overall, findings showed compensation processes in social identification: When social comparison is salient, members of a low morality group base identification on the dimension which allows positive differentiation from the outgroup.
