Attentional bias in anxiety: a behavioral and ERP study

Accumulating evidence suggests the existence of a processing bias in favor of threat-related stimulation in anxious individuals. Using behavioral and ERP measures, the present study investigated the deployment of attention to face stimuli with different emotion expressions in high-anxious and low-anxious participants. An attention-shifting paradigm was used in which faces with neutral, angry, fearful, sad, or happy expressions were presented singly at fixation. Participants had to fixate on the face cue and then discriminate a target shape that appeared randomly above, below, to the left, or right of the fixated face. The behavioral data show that high-anxious participants were slower to respond to targets regardless of the emotion expressed by the face cue. In contrast, the ERP data indicate that threat-related faces elicited faster latencies and greater amplitudes of early ERP components in high-anxious than in low-anxious individuals. The between-group pattern in ERP waveforms suggests that the slower reaction times in high-anxious participants might reflect increased attentional dwelling on the face cues, rather than a general slowing of response enacting.     

The effects of learned helplessness on the processing of a persuasive message

The current study examines the effects of exposure to unsolvable problems on the processing of a persuasive message. Participants exposed to either unsolvable failure or no-feedback tasks were presented with one of four versions of an advertisement about a hair shampoo and rated their attitude towards this product. Two aspects of the message were manipulated: the quality of arguments (strong, weak) and the attractiveness of the communicator (attractive, non-attractive). In addition, participants rated their anxiety and the frequency of off-task thoughts during the experiment. Attitude towards the target product of participants in the failure condition was less affected by the argument’s quality and more influenced by communicator attractiveness than the attitude of participants in the no-feedback condition. Participants exposed to failures reported more anxiety and task-related worries than those exposed to no-feedback, and these ratings were found to mediate the effects of failure on the processing of a persuasive message. Results were discussed in terms of Learned Helplessness theories and the Elaboration Likelihood Model.     

Personality and Charismatic Leadership in Context: The Moderating Role of Situational Stress

We adopt an interactionist perspective and extend previous work on personality and charismatic leadership by considering the relationship between them across contexts. Based on Gray's reinforcement sensitivity theory, we expected the relationships between approach‐oriented dispositions and charisma to diminish under conditions of high workload‐induced stress. In a large‐scale lab study with 201 groups (Study 1, N = 721 participants), we manipulated conditions of stress and tested the interaction of stress with leaders’ extraversion and openness to experience in predicting their charismatic behaviors. We then tested, in a field study of 71 executives (Study 2, N = 256 participants), the interaction of employees’ reported stress with leaders’ stimulation values in predicting their charismatic behavior. In support of our hypotheses, the relationships between approach‐oriented dispositions and charisma were significantly weaker when stress was high. We discuss theoretical and practical implications of this finding, in particular given that it is in stressful conditions under which charismatic leadership is said to be most important.     

Depth perception: cuttlefish (Sepia officinalis) respond to visual texture density gradients

Studies concerning the perceptual processes of animals are not only interesting, but are fundamental to the understanding of other developments in information processing among non-humans. Carefully used visual illusions have been proven to be an informative tool for understanding visual perception. In this behavioral study, we demonstrate that cuttlefish are responsive to visual cues involving texture gradients. Specifically, 12 out of 14 animals avoided swimming over a solid surface with a gradient picture that to humans resembles an illusionary crevasse, while only 5 out of 14 avoided a non-illusionary texture. Since texture gradients are well-known cues for depth perception in vertebrates, we suggest that these cephalopods were responding to the depth illusion created by the texture density gradient. Density gradients and relative densities are key features in distance perception in vertebrates. Our results suggest that they are fundamental features of vision in general, appearing also in cephalopods.     

Psychologists’ Evaluation of Bariatric Surgery Candidates Influenced by Patients’ Attachment Representations and Symptoms of Depression and Anxiety

This study examines whether patients self-reported attachment representations and levels of depression and anxiety influenced psychologists’ evaluations of morbidly obese patients applying for bariatric surgery. A sample of 250 patients (mean age 44, 84 % female) who were referred for bariatric surgery completed questionnaires to measure adult attachment and levels of depression and anxiety. Psychologists rated patients’ suitability for bariatric surgery using the Cleveland Clinic Behavioural Rating System (CCBRS), unaware of the results of the completed questionnaires. Attachment anxiety (OR = 2.50, p = .01) and attachment avoidance (OR = 3.13, p = .001) were found to be associated with less positive evaluations on the CCBRS by the psychologists, and symptoms of depression and anxiety mediated this association. This study strongly supports the notion that patients’ attachment representations influence a psychologist’s evaluation in an indirect way by influencing the symptoms of depression and anxiety patients report during an assessment interview. The clinical implications of these findings are discussed.     

The messianic temporality of theatre in I. L. Peretz’s At Night in the Old Marketplace

Theatre, as an art form that unfolds through time and moulds temporal experience, engages with its surrounding culture’s temporal imagination, the ways in which society conceives time, its movement, structures, and meaning. I. L. Peretz’s enigmatic and avant-garde Yiddish drama, At Night in the Old Marketplace, utilizes this potential of the theatre to tackle the question of messianic time and the ways in which it can be realized on the stage. By evoking Jewish traditions regarding the Messiah, religious nocturnal rituals, and the dynamics of Carnival, Peretz reconfigures messianic time as a radical, recurring yet fleeting, temporal experience. Theatrical temporality has affinities with messianic time because both are transitory and charged, condensed and ephemeral, and disjointed from the experience of time in everyday life. Rather than imagining messianic time as an eternal future to be awaited, Peretz’s play invites us to ponder in the theatre about the possibility of a messianically charged, albeit always fleeting, present.

The role of text representation in students' ability to identify fallacious arguments

Informal reasoning fallacies are arguments that, though they may seem persuasive, are not valid. The psychological aspect of informal reasoning fallacies, specifically the identification of factors that influence students' ability to identify fallacies, has not been the subject of empirical study. The aim of this study was to test the hypothesis that subjects' ability to identify fallacious arguments is associated with the representation of the argumentative text in the cognitive system. In the first experiment, we tested the hypothesis through a recall task. In the second experiment, we tested the hypothesis through a classification task. The results of the experiments confirm the research hypothesis and point to the role of argumentative structures in argumentation tasks.
