Exogenous spatial attention influences figure-ground assignment

Abstract— In a hierarchical stage account of vision, figure-ground assignment is thought to be completed before the operation of focal spatial attention. Results of previous studies have supported this account by showing that unpredictive, exogenous spatial precues do not influence figure-ground assignment, although voluntary attention can influence figure-ground assignment. However, in these studies, attention was not summoned directly to a region in a figure-ground display. In three experiments, we addressed the relationship between figure-ground assignment and visuospatial attention. In Experiment 1, we replicated the finding that exogenous precues do not influence figure-ground assignment when they direct attention outside of a figure-ground stimulus. In Experiment 2, we demonstrated that exogenous attention can influence figure-ground assignment if it is directed to one of the regions in a figure-ground stimulus. In Experiment 3, we demonstrated that exogenous attention can influence figure-ground assignment in displays that contain a Gestalt figure-ground cue; this result suggests that figure-ground processes are not entirely completed prior to the operation of focal spatial attention. Exogenous spatial attention acts as a cue for figure-ground assignment and can affect the outcome of figure-ground processes.

The return of object-based attention: selection of multiple-region objects

Objects can control the focus of attention, allowing features on the same object to be selected more easily than features on different objects. In the present experiments, we investigated the perceptual processes that contribute to such object-based attentional effects. Previous research has demonstrated that object-based effects occur for single-region objects but not for multiple-region objects under some conditions (Experiment 1, Watson & Kramer, 1999). Such results are surprising, because most objects in natural scenes are composed of multiple regions. Previous findings could therefore limit the usefulness of an object-based selection mechanism. We explored the generality of these single-region selection results by manipulating the extent to which different (i.e., multiple) regions of a single object perceptually grouped together. Object-based attentional effects were attenuated when multiple regions did not group into a single perceptual object (Experiment 1). However, when multiple regions grouped together based on (1) edge continuation (Experiments 2 and 3) or (2) part and occlusion cues (Experiment 4), we observed object-based effects. Our results suggest that object-based attention is a robust process that can select multiple-region objects, provided the regions of such objects cohere on the basis of perceptual grouping cues.     

Event-related FMRI study of context processing in dorsolateral prefrontal cortex of patients with schizophrenia

Context processing is conceptualized as an executive function involved in voluntary, complex actions such as overcoming automatic responses. The present study tested the hypothesis that context-processing deficits in patients with schizophrenia are associated with a dysfunction of left dorsolateral prefrontal cortex (DLPFC). Using event-related functional magnetic resonance imaging (fMRI), 17 controls and 17 medicated patients performed a version of the AX task in which a learned, automatic response had to be inhibited. In controls, left DLPFC activity increased when preparing to overcome an automatic response, whereas patients with schizophrenia showed no differential activation. In controls, context processing appeared to be associated with the differential representation of cues associated with the need to provide top-down support for overcoming automatic responses. This mechanism appeared to be impaired in patients with schizophrenia.     

Family Resilience and the Management of Fibromyalgia: Implications for Family Therapists

Fibromyalgia Syndrome (FMS) is one of the most troubling rheumatic disorders for patients, significant others, and the health care providers who treat them. Responses from 150 participants provided valuable information on the relationship between family resilience and the management of fibromyalgia. Self reported family stressors, strains, and distress were significantly associated with an increase in health problems/functional disability, whereas family hardiness and family social support were associated with a decrease. Family stressors and family strains were also positively associated with the frequency of medication use. Medical family therapy interventions that consider the familial context are recommended for treatment. Additional implications for clinical practice and future research are discussed. J.

The experience of power: examining the effects of power on approach and inhibition tendencies

Two studies of task-focused dyads tested the approach/inhibition theory of power (D. Keltner, D. H. Gruenfeld, & C. Anderson, in press), which posits that having power increases the tendency to approach and decreases the tendency to inhibit. Results provided preliminary support for the theory: Participants higher in personality dominance or assigned control over resources expressed their true attitudes, experienced more positive and less negative emotion, were more likely to perceive rewards (i.e., that their partner liked them), and were less likely to perceive threats (e.g., that their partner felt anger toward them). Most of these effects were mediated by the sense of power, suggesting that subjective feelings of power are an important component in the effects of power.     

When the face reveals what words do not: facial expressions of emotion,smiling, and the willingness to disclose childhood sexual abuse

For survivors of childhood sexual abuse (CSA), verbal disclosure is often complex and painful. The authors examined the voluntary disclosure-nondisclosure of CSA in relation to nonverbal expressions of emotion in the face. Consistent with hypotheses derived from recent theorizing about the moral nature of emotion, CSA survivors who did not voluntarily disclose CSA showed greater facial expressions of shame, whereas CSA survivors who voluntarily disclosed CSA expressed greater disgust. Expressions of disgust also signaled sexual abuse accompanied by violence. Consistent with recent theorizing about smiling behavior, CSA nondisclosers made more polite smiles, whereas nonabused participants expressed greater genuine positive emotion. Discussion addressed the implications of these findings for the study of disclosure of traumatic events, facial expression, and the links between morality and emotion.     

Assessing the social validity of telehealth-based applied behavior analysis services for autism spectrum disorder

During the COVID-19 pandemic, applied behavior analysis services for many autistic individuals were transitioned to telehealth. The current study assessed caregiver-reported quality of life (QoL) and social validity for families of autistic children receiving only telehealth services (n = 96) or a combination of telehealth and in-person services (n = 173). Barriers to the telehealth experience were analyzed via an ANOVA, and the impact of funding source was analyzed using an independent samples t-test. Caregivers reported benefit across QoL and social validity items, with scores ranging from 3.31 to 4.44 (1 = least benefit, 5 = most benefit). While many caregivers reported no barriers regarding technology (44.61%), childcare (69.52%), and employment (64.68%), the presence of those barriers significantly impacted QoL and social validity scores. Funding source was not found to have a significant impact. Overall, caregivers found value in their child's telehealth services. Clinicians have an obligation to mitigate barriers to ensure the success of the intervention.     

Associations between power,stress, and dominance in romantic relationships during the COVID-19 pandemic: Examining curvilinear and within-person effects

Two key processes in romantic relationships—power and dominance—can contribute to relationship disruption, but the association between these variables is complex. Elucidating the association between power and dominance during the COVID-19 pandemic is particularly important given the economic, social, and health-related stressors that pose a risk to relationship health. We examined associations between power, stress, and dominance by recruiting 1813 participants to complete an initial online survey at the beginning of the COVID-19 pandemic. Participants were contacted 10 and 22 months later to complete follow-up surveys. Results revealed two main effects: individuals who had greater relationship power and experienced more COVID-19-related stressors than other people engaged in more dominance behaviors. A significant curvilinear effect revealed that at low levels of power, power was not associated with dominance behaviors. However, once power surpassed low levels, individuals with more power engaged in more dominance behaviors. Finally, people engaged in more dominance behaviors when they experienced more power and stress compared to their own average (i.e., within-person effects) during the pandemic. Implications for theories of power, dominance, and relationship disruption and distress are discussed.     

Body-image and eating disturbances predict onset of depression among female adolescents: a longitudinal study

This study examined data from a 4-year school-based longitudinal study (n = 1,124), to test whether the increase in major depression that occurs among girls during adolescence may be partially explained by the body-image and eating disturbances that emerge after puberty. Elevated body dissatisfaction, dietary restraint, and bulimic symptoms at study entry predicted onset of subsequent depression among initially nondepressed youth in bivariate analyses controlling for initial depressive symptoms. Although the unique effect for body dissatisfaction was not significant in the multivariate model, this set of risk factors was able to fairly accurately foretell which girls would go on to develop major depression. Results were consistent with the assertion that the body-image- and eating-related risk factors that emerge after puberty might contribute to the elevated rates of depression for adolescent girls.
