Eye movements and bisection behavior in spatial neglect syndrome: representational biases induced by the segment length and spatial dislocation of the stimulus

The present study explored behavioral and eye-movement measures in unilateral neglect patients in response to online bisection task (unfilled gap line). Two different tasks supported the bisection performance, a pointing and a grasping strategy. It was explored whether these different strategies may influence subjects’ behavioral and eye-movement measures in response to different segment features: segment length (from shorter to longer) and segment spatial dislocation (from right to left spatial location). Consistent spatial biases were found for both bisection responses, fixation count, and duration, as well as for the first fixation count in case of pointing task. An “extreme-left” gradient effect was suggested and discussed, with patients’ behavioral and eye measures more impaired. On the contrary, the patients’ performance overlaps with the controls’ one in case a grasping task. The direct link of visual pointing and grasping strategy, respectively, with the two cortical ventral and dorsal pathways was adduced to explain our results.     

Effectiveness of parent counselling in eating disorders

ABSTRACT

Eating Disorders (ED) are often severe illnesses entailing a heavy burden for families. Family therapy is recommended for young patients, but only a few studies have investigated therapeutic interventions with families tailored also to adult and longstanding patients. We recruited 87 families with daughters affected by an ED, aiming to assess the effectiveness of eight sessions of parent counselling. The primary outcome was the improvement of parents' coping abilities to achieve more effective support skills. Before treatment, 54% of parents showed poor coping resources whereas 43.7% of the sample improved after parent counselling. Parents with good coping resources responded significantly better to this treatment. Although future research is warranted, these preliminary findings support the effectiveness of parent counselling in ED.     

The strategic role of language abstraction in achieving symbolic and practical goals

This article addresses the role of linguistic abstraction in the achievement of symbolic and practical goals. Reviewing evidence from laboratory studies, we first elaborate on the power of language as a means of ingroup enhancement or outgroup derogation under different intergroup conditions. We then report several experimental and archival studies that showed how language serves the achievement of different practical goals such as initiating, maintaining, and ending romantic relations, accounting for individual and group decisions, maintaining or obtaining political and gender power, and persuading others. The analysis of open-ended language measures—which represents a methodological thread of the reviewed studies—shows how language is strategically moulded according to individual and group goals in laboratory as well as in real-life contexts. The implications of the interplay among language, cognition, and action are addressed.     

Urban Conflicts and Immigrants’ Engagement. A Comparative Pragmatic Analysis of Two Northern Italian Cities

At the beginning of the 1990s, urban safety entered political and media debates in Italy. Since then, an anti-social behaviour discourse has diverted attention towards newcomers who have repeatedly appeared as the main cause of urban safety conflicts. Italian scholars have often described these actors as the passive target of safety policies. The main aim of this paper is to demonstrate that in fact some residents of immigrant origins have engaged in the game of urban conflicts. A comparative analysis will be carried out to discuss contentious dynamics in two Italian cities, by building on ethnographical data collected between 2009 and 2010. The two cities which are the object of the analysis are Verona and Modena. They are situated in the so-called Third Italy, in the north of the country, and are characterised by diverging political subcultures. A consistent part of studies on immigrants’ collective action has drawn from the structural perspective and has insisted on political opportunities as a crucial explanatory variable. This contribution will show the added value of complementing this interpretation with a pragmatic sensitive one. Residents of immigrant origins will be observed while undertaking their thorny path of engagement characterised by the capacity to adapt, construct more or less lasting agreements with institutional and non-institutional actors and propose alternative solutions to influence a given context. Ultimately, this will also provide an example of how a pragmatic sensitive stance can help study politics in a continuum with policies, a preoccupation which lies at the core of urban theory.     

IRT Test Equating in Complex Linkage Plans

Linkage plans can be rather complex, including many forms, several links, and the connection of forms through different paths. This article studies item response theory equating methods for complex linkage plans when the common-item nonequivalent group design is used. An efficient way to average equating coefficients that link the same two forms through different paths will be presented and the asymptotic standard errors of indirect and average equating coefficients are derived. The methodology is illustrated using simulations studies and a real data example.     

In the face of emotions: event-related potentials in supraliminal and subliminal facial expression recognition

Is facial expression recognition marked by specific event-related potentials (ERPs) effects? Are conscious and unconscious elaborations of emotional facial stimuli qualitatively different processes? In Experiment 1, ERPs elicited by supraliminal stimuli were recorded when 21 participants viewed emotional facial expressions of four emotions and a neutral stimulus. Two ERP components (N2 and P3) were analyzed for their peak amplitude and latency measures. First, emotional face-specificity was observed for the negative deflection N2, whereas P3 was not affected by the content of the stimulus (emotional or neutral). A more posterior distribution of ERPs was found for N2. Moreover, a lateralization effect was revealed for negative (right lateralization) and positive (left lateralization) facial expressions. In Experiment 2 (20 participants), 1-ms subliminal stimulation was carried out. Unaware information processing was revealed to be quite similar to aware information processing for peak amplitude but not for latency. In fact, unconscious stimulation produced a more delayed peak variation than conscious stimulation.     

Downward comparison in everyday life: reconciling self-enhancement models with the mood-cognition priming model

Two models concerning downward comparison are motivational; they predict that when people are unhappy, they make downward comparisons to self-enhance (e.g., Wills, 1981). In contrast, the affect-cognition priming model (Wheeler & Miyake, 1992) predicts that unhappy people make upward comparisons because negative affect makes mood-congruent comparisons more accessible. The authors propose that both motivational and accessibility factors influence social comparisons. A study of undergraduates' self-recorded everyday comparisons supported this view. In addition, results (a) pointed to motivational influences other than self-enhancement and an accessibility influence other than mood-congruent priming, (b) suggested that motivated and unintended comparisons may differ somewhat in their susceptibility to motivational and accessibility influences, and (c) identified challenges to both self-enhancement and priming models.     

Is empathy necessary to comprehend the emotional faces? The empathic effect on attentional mechanisms (eye movements), cortical correlates (N200 event-related potentials) and facial behaviour (electromyography) in face processing

The present research explored the effect of social empathy on processing emotional facial expressions. Previous evidence suggested a close relationship between emotional empathy and both the ability to detect facial emotions and the attentional mechanisms involved. A multi-measure approach was adopted: we investigated the association between trait empathy (Balanced Emotional Empathy Scale) and individuals' performance (response times; RTs), attentional mechanisms (eye movements; number and duration of fixations), correlates of cortical activation (event-related potential (ERP) N200 component), and facial responsiveness (facial zygomatic and corrugator activity). Trait empathy was found to affect face detection performance (reduced RTs), attentional processes (more scanning eye movements in specific areas of interest), ERP salience effect (increased N200 amplitude), and electromyographic activity (more facial responses). A second important result was the demonstration of strong, direct correlations among these measures. We suggest that empathy may function as a social facilitator of the processes underlying the detection of facial emotion, and a general “facial response effect” is proposed to explain these results. We assumed that empathy influences cognitive and the facial responsiveness, such that empathic individuals are more skilful in processing facial emotion.     

What Demonstrative Induction Can Do Against the Threat of Underdetermination: Bohr,Heisenberg, and Pauli on Spectroscopic Anomalies (1921–24)

In this paper I argue that demonstrative induction can deal with the problem ofthe underdetermination of theory by evidence. I present the historical case studyof spectroscopy in the early 1920s, where the choice among different theorieswas apparently underdetermined by spectroscopic evidence concerning the alkalidoublets and their anomalous Zeeman effect. By casting this historical episodewithin the methodological framework of demonstrative induction, the localunderdetermination among Bohr's, Heisenberg's, and Pauli's rival theories isresolved in favour of Pauli's theory of the electron's spin.     

School Sense of Community,Teacher Support,and Students’ School Safety Perceptions

This study examined the association between two characteristics of school climate (sense of community and teacher support, measured both at the individual and at the school level) and students’ feelings of being unsafe at school. The study involved a sample of 49,638 students aged 10–18 years who participated in the 2010–2012 California Healthy Kids Survey. Using hierarchical linear modeling (HLM), our findings revealed that, at the individual level, students perceiving higher levels of sense of community and teacher support at school were less likely to feel unsafe within the school environment. At the school level, sense of community was negatively associated with unsafe feelings, whereas there was no association between school‐level teacher support and feelings of being unsafe at school.
