TMS over the superior temporal sulcus affects expressivity evaluation of portraits

When viewing a portrait, we are often captured by its expressivity, even if the emotion depicted is not immediately identifiable. If the neural mechanisms underlying emotion processing of real faces have been largely clarified, we still know little about the neural basis of evaluation of (emotional) expressivity in portraits. In this study, we aimed at assessing—by means of transcranial magnetic stimulation (TMS)—whether the right superior temporal sulcus (STS) and the right somatosensory cortex (SC), that are important in discriminating facial emotion expressions, are also causally involved in the evaluation of expressivity of portraits. We found that interfering via TMS with activity in (the face region of) right STS significantly reduced the extent to which portraits (but not other paintings depicting human figures with faces only in the background) were perceived as expressive, without, though, affecting their liking. In turn, interfering with activity of the right SC had no impact on evaluating either expressivity or liking of either paintings’ category. Our findings suggest that evaluation of emotional cues in artworks recruit (at least partially) the same neural mechanisms involved in processing genuine biological others. Moreover, they shed light on the neural basis of liking decisions in art by art-naïve people, supporting the view that aesthetic appreciation relies on a multitude of factors beyond emotional evaluation.     

Gender differences in memory for object and word locations

It has been hypothesized that gender differences in visuo-spatial working memory (VSWM) are larger in tasks requiring active elaboration of the material. In the present study we explored this issue by using an object relocation task, with both verbal and visual stimuli. The involvement of active processes was manipulated through the type of transformation required on the stimulus and through the introduction of different kinds of interference. In the three experiments reported, participants were shown either words or cartoon object icons in different locations and had to relocate them in either the same format or in the opposite one (object icons could be transformed into words and vice versa). Males outperformed females in the most demanding conditions, in which object icons and words were presented together in the encoding phase, and both had to be transformed in the recall phase; or when more demanding interferences were used. Our data suggest that the retention strategy was similar for the two groups and that the gender effect is related to a selective female difficulty associated with the increase in active VSWM processing. These findings further support the hypothesized distinction between the passive and active components of VSWM and illustrate the role that this distinction might play in accounting for individual differences.     

Fuzzy intuitionistic quantum logics

Fuzzy intuitionistic quantum logics (called also Brouwer-Zadeh logics) represent to non standard version of quantum logic where the connective not is split into two different negation: a fuzzy-like negation that gives rise to a paraconsistent behavior and an intuitionistic-like negation. A completeness theorem for a particular form of Brouwer-Zadeh logic (BZL ³) is proved. A phisical interpretation of these logics can be constructed in the framework of the unsharp approach to quantum theory.     

A Transconceptual Model of Empowerment and Resilience: Divergence, Convergence and Interactions in Kindred Community Concepts

Resilience and empowerment are widely employed concepts in community psychology and other social sciences. Although empowerment is more closely associated with community psychology, both concepts hone to community psychology’s strengths-based values, recognizing, respecting, and promoting local capacity and positive outcomes. Both concepts also have been critiqued for lacking clear consensus regarding definition, operationalization, and measurement (Cattaneo and Chapman in Am Psychol 65(7):646–659, 2010; Luthar et al. in Child Dev 71(3):543–562, 2000). This deficiency is reflected in the wide ranging applications of each term independently, and is particularly concerning when the terms are used together or interchangeably. Theoretical work on these concepts’ boundaries and interaction is lacking. This paper builds on the authors’ prior work operationalizing the processes and outcomes of each concept (Brodsky et al. in Am J Community Psychol 47(3–4):217–235, 2011; Cattaneo and Chapman in Am Psychol 65(7):646–659, 2010; Cattaneo and Goodman in Psychol Violence, in press) to present a combined transconceptual model illuminating the divergence, convergence, and interactions between the two. Both resilience and empowerment are fueled by unsatisfying states, but are differentiated by, among other things, internally (resilience) versus externally (empowerment) focused change goals. Goal determinants include context, power differentials, and other risks and resources. These concepts have the potential to facilitate each other, and understanding their interaction can better inform community psychologists’ work with marginalized populations.     

Work‐Group Membership (In)Stability and Survivors' Reactions to Organizational Downsizing1

This longitudinal panel study investigated the interactive effect of work‐group membership stability and time on survivors' reactions to organizational downsizing. The participants were 159 nonmanagement employees of a federal government department. Survivors in moderate‐change work groups did not react more negatively to the downsizing. In fact, they reported a significant increase in job satisfaction, job security, job performance, and employee morale. Survivors who changed to different work groups expressed the least positive attitudes in the initial phase of the downsizing, but the most positive attitudes at the completion of the downsizing. Work‐group membership (in)stability was more likely to affect survivors' reactions to various aspects of their job over time than factors related to the work group itself.     

Visual symmetry perception in early onset monocular blindness

Symmetry detection is impaired by abnormal binocular vision development such as in amblyopia. However, the detection of symmetry has never been investigated in cases where input from one eye is profoundly compromised. Testing monocularly blind (MB) individuals represents a unique opportunity to investigate whether symmetry salience relies on a normally developed binocular visual system. In a visual symmetry detection task using dot patterns, congenitally MB showed comparable accuracy to normally sighted individuals viewing monocularly. This included better detection of vertically than horizontally symmetric patterns. However, the MB were slower than controls in detecting a symmetrical pattern. In a control target-detection task, no significant differences in performance were observed between these groups. Overall, normal developing binocular vision does not appear necessary for the visual system to detect the presence of visual symmetry. However, optimal detection mechanisms may be dependent on binocular summation or other processes dependent on input from both eyes.     

Monitoring eye movements to investigate the picture superiority effect in spatial memory

Spatial memory is usually better for iconic than for verbal material. Our aim was to assess whether such effect is related to the way iconic and verbal targets are viewed when people have to memorize their locations. Eye movements were recorded while participants memorized the locations of images or words. Images received fewer, but longer, gazes than words. Longer gazes on images might reflect greater attention devoted to images due to their higher sensorial distinctiveness and/or generation with images of an additional phonological code beyond the visual code immediately available. We found that words were scanned mainly from left to right while a more heterogeneous scanning strategy characterized encoding of images. This suggests that iconic configurations tend to be maintained as global integrated representations in which all the item/location pairs are simultaneously present whilst verbal configurations are maintained through more sequential processes.     

From Moment to Movement: Empowerment and Resilience as a Framework for Collective Action in Hong Kong

The Transconceptual Model of Empowerment and Resilience (American Journal of Community Psychology, 52, 2013, 333) suggests that a set of resilience and empowerment resources fuel both initial and sustained participation in collective action. Using the case study of a prodemocracy movement in Hong Kong, the present study focused on the subset of those resources that are relevant in ongoing collective action: efficacy, skills, and maintenance. As individuals possess varying combinations of these resources, the present study utilized latent profile analysis to test how patterns of empowerment and resilience resources influence initial and long‐term collective action. Five groups were identified: (a) Uncommitted/Uninspired; (b) Committed to Status Quo; (c) Mainstream Populist; (d) Empowered; and (e) Ambivalent. ANOVA and ANCOVA analyses found that there are significant group differences in initial and long‐term participation. Groups with higher level of resources reported greater levels of initial participation than their counterparts; however, high resource groups did not uniformly report greater levels of intention to participate in future collective action. Of the maintenance processes tested, collective identity emerged as a particularly important predictor differentiating initial and sustained participation. Findings from the present study raise questions about how individuals with multiple identities can come together and participate in collective action.     

Elaborating the Connection between Social Class and Classism in College

Scholarship has documented the challenges that face college students of marginalized economic backgrounds, an issue that is relevant for Community Psychology because of the field's commitment to social justice. Community psychologists are concerned with facilitating access to social resources such as education across the full range of social identities. The current study builds on recent research that has identified the key role of classism in students' struggles. We developed a new measure of college student financial stress in order to investigate the relationship between indices of social class (financial stress, subjective social status, and parental education) and indices of classism (institutional, interpersonal, and citational). We also explored whether race or immigration status moderated these relationships in a sample of diverse students (N = 278). Findings show that students' current financial stress has the strongest relationship with classism, and immigration status moderates the exposure to citational classism. Specifically, we found evidence for perpetuation of classism among U.S. born students higher on the social class ladder. Implications for future research include the importance of considering multiple domains of social class, studying social class in a context‐specific way, and differentiating dimensions of classism. Findings also suggest that financial stress is an important focus in the work to support marginalized students, and that classist narratives need to be addressed among students of higher social class.
