Task-irrelevant visual motion and flicker attenuate the attentional blink

Our reduced ability to correctly report two sequentially presented targets is seen in the robust effect known as the attentional blink (AB; Raymond, Shapiro, & Arnell, 1992). One recent report (Olivers & Nieuwenhuis, 2005) strikingly reveals the AB to be virtually abolished when non-task-demanding music occurs in the background. The authors suggest that a diffuse attentional state is the mediating factor. Here, we seek to broaden the finding’s generality by determining if task-irrelevant visual motion and flicker also attenuate the AB. In our experiments, the AB task was presented together with a background field of moving dots that could moveaway from ortoward the central AB task, or flicker. In the control condition, the dots remained static. The AB was attenuated—though to different degrees—in all experimental conditions, but not in the static condition. Our findings add to the generality of the previous conclusions, and we emphasize an account based on the overallocation of attention.     

Dissociating viewpoint costs in mental rotation and object recognition

In a mental rotation task, participants must determine whether two stimuli match when one undergoes a rotation in 3-D space relative to the other. The key evidence for mental rotation is the finding of a linear increase in response times as objects are rotated farther apart. This signature increase in response times is also found in recognition of rotated objects, which has led many theorists to postulate mental rotation as a key transformational procedure in object recognition. We compared mental rotation and object recognition in tasks that used the same stimuli and presentation conditions and found that, whereas mental rotation costs increased relatively linearly with rotation, object recognition costs increased only over small rotations. Taken in conjunction with a recent brain imaging study, this dissociation in behavioral performance suggests that object recognition is based on matching of image features rather than on 3-D mental transformations.     

Low-income African American women's attempts to convince their main partner to use condoms

In this cross-sectional study the authors examine condom use attempts and condom use among 305 high-risk, low-income African American women who reported having a main partner. Women who had recently attempted to convince their main partner to use condoms were almost 10 times more likely to have recently used condoms with their partner than women who had not made an attempt. Among the subsample of 116 women who had recently made a condom use attempt with their main partner, having a history of childhood abuse and having one's main partner raise infidelity questions in response to the condom use attempt were negatively associated with recent condom use with this partner. Findings provide initial insights into the importance of women's condom use attempts, as well as subgroups of women who may encounter special challenges convincing their main partner to use condoms.     

The development of a culturally informed, family-focused treatment for schizophrenia

With the changing demographics in the United States, there is an increasing need for psychotherapy interventions that have been tailored for and empirically evaluated with culturally diverse groups. This article discusses the development and evaluation of a family-focused, culturally informed therapy for schizophrenia (CIT-S) that is currently being pilot tested at the University of Miami. Case examples of CIT-S with participating families are provided, along with a discussion of interesting and challenging cultural issues that we have encountered during the pilot phase of this treatment study.     

Font tuning associated with expertise in letter perception

Font tuning (FT) occurs when observers recognize a sequence of letters presented in the same font faster than in different fonts (Sanocki 1987, 1988 Journal of Experimental Psychology. Human Perception and Performance 13 267-278; 14 472-480). Here, we test the hypothesis that FT is associated with expertise with a specific writing system. We developed a systematic search task allowing the measurement of FT over a large number of letters and generalized the finding of FT from English readers viewing Roman letters to Chinese readers viewing Chinese characters. Non-Chinese readers did not show evidence of FT for Chinese characters in this search task. We also used a simpler 3-letter identification task to directly compare novice and expert readers, and to explore FT for different aspects of font such as fill, slant, and aspect ratio. We found that experts tune to aspect ratio but not to the other font changes. These findings reveal that letters are not processed visually in the same manner as shapes, and suggest an explanation for the cortical specialization obtained in the visual system for letters.     

Work-related stress and well-being: the roles of direct action coping and palliative coping

The purpose of the present study is to analyze the roles of direct action coping and palliative coping in the relationship between work stressors and psychological well-being, as well as their possible interactions, in a sample of 464 bank employees. Hierarchical regression analyses showed main effects of direct action coping on well-being. Palliative coping predicts higher levels of psychological distress. Contrary to what was expected, the interactions between work stressors and direct action coping were not significant. Palliative coping interacted with work stressors when predicting psychosomatic complaints. The interaction between the two types of coping was significant on psychosomatic complaints and psychological distress, but not on job satisfaction. The paper discusses theoretical and practical implications of these results, in order to design intervention strategies to prevent and manage job stress.     

Personal and general belief in a just world as judgement norms

Research on the belief in a just world (BJW) has focused on its intra-individual functions (e.g., psychological well-being) and its inter-individual consequences (e.g., derogation of victims). Recent theorizing, however, has indicated that the BJW may also have more societal functions and consequences, serving as a legitimizing device of the status quo. The studies in the current paper focus on this latter view and are based on Alves and Correia's ( 2008 ) research which found that the expression of high personal and general belief in a just world is injunctively normative. Two experimental studies aimed at ascertaining three issues: (1) the dimension(s) of social value (social utility and/or social desirability) on which the BJW normativity anchors; (2) whether the expression of moderate BJW is also injunctively normative; and (3) whether the injunctive normativity of the BJW is related to perceptions of truth. Results indicate that moderate and high personal and general BJW are normative. Yet, whereas the normativity of personal BJW anchors both on social utility and social desirability, that of general BJW anchors only on social utility. We discuss personal and general BJW as judgement norms, whose normativity may not be personally acknowledged (in the case of general BJW) and does not necessarily derive from being perceived as true, but from the fact that such norms carry social value at least in individualistic societies.     

Learned preference for a hedonically negative flavor is observed after pairings with positive post-ingestion consequences rather than with a palatable flavor

In two experiments, thirsty rats consumed a compound of sucrose and a non-preferred flavor. In Experiment 1, a conditioned preference was observed in the experimental group when animals were tested both thirsty and hungry, but not when they were tested just thirsty. Animals in the control group, which experienced the flavor and the sucrose unpaired, never showed a preference. Experiment 2 replicated the absence of a preference in the experimental group when rats were tested thirsty, but provided evidence that a flavor-taste association had been formed during training. After conditioning, sucrose was paired with LiCl in group Dev whereas it was unpaired in group NonDev. The sucrose devaluation produced a decrease in CS preference in group Dev, and an increment in group NonDev. Taken together, these results show that preference for a non-preferred flavor can be readily observed after pairings with the positive consequences of the US (calories or absence of an expected illness) rather than with a palatable flavor.     

Above and beyond emotional valence: The unique contribution of central and traumatic shame memories to psychopathology vulnerability

This paper explores whether shame memories have a distinct impact on emotional difficulties and psychopathology that goes beyond their negative emotional valence. Study 1 (N=292) investigates the contribution of centrality of shame memory, in comparison to the centrality of fear and sadness memories, to explain the memory's traumatic impact, shame, depression, anxiety, stress, paranoid, and dissociative symptoms. Study 2 (N=192) explores the impact of shame traumatic memory on shame and depression, anxiety, and stress symptoms, in comparison to fear and sadness traumatic memories. Both studies used undergraduate student samples. Results show that shame memories' centrality and traumatic features made an independent contribution to current external and internal shame and distinct psychopathological symptoms, after controlling for the effect of fear and sadness, centrality, and traumatic qualities. Moreover, shame memories' centrality and traumatic features were the best global predictors of external and internal shame and depressive symptoms. Centrality of shame memories was also the only significant predictor of paranoid ideation and dissociation. These results offer novel perspectives on the nature of shame and its relation to psychopathology, emphasising the distinct role of shame memories in human functioning and suffering, which goes above and beyond its negative emotional valence.
