Information processing biases and panic disorder: relationships among cognitive and symptom measures

To test cognitive models of panic disorder, a range of information processing biases were examined among persons with panic disorder (N=43) and healthy control participants (N=38). Evidence for automatic associations in memory was assessed using the Implicit Association Test, interference effects related to attention biases were assessed using a modified supraliminal Stroop task, and interpretation biases were assessed using the Brief Body Sensations Interpretation Questionnaire. In addition, the relationship between information processing biases and clinical markers of panic (including affective, behavioral, and cognitive symptom measures) was investigated, along with the relationships among biases. Results indicated more threat biases among the panic (relative to control) group on each of the information processing measures, providing some of the first evidence for an implicit measure of panic associations. Further, structural equation modeling indicated that the information processing bias measures were each unique predictors of panic symptoms, but that the bias indicators did not relate to one another. These findings suggest that cognitive factors may independently predict panic symptoms, but not covary. Results are discussed in terms of their support for cognitive models of panic and the potential for automatic versus strategic processing differences across the tasks to explain the low relationships across the biases.     

Do socially anxious individuals fear embarrassment by close others? Development of the Fear of Embarrassment by Others Scale

Social anxiety disorder is characterized by an intense fear of social or performance situations, and a fear of acting in a way that will be humiliating or embarrassing. However, the extent to which socially anxious individuals fear embarrassment due to the behavior of close others remains unknown. The Fear of Embarrassment by Others Scale (FEOS) was developed to assess the extent to which individuals with social anxiety fear being embarrassed by others. To assess the psychometric properties of this measure, 162 undergraduate students low or high in social anxiety completed the FEOS, along with additional questionnaires. An exploratory factor analysis suggested a single factor. The measure demonstrates high internal consistency, and is correlated with measures of social anxiety, fear of negative evaluation, and anxiety sensitivity. Fear of embarrassment by others was not found to be a significant predictor of social anxiety, as compared to anxiety sensitivity and fear of negative evaluation. The FEOS discriminated among participants high and low in social anxiety, as those high in social anxiety scored significantly higher on the measure than did participants low in social anxiety. The utility of this scale for research and clinical practice is discussed.     

The naked truth: Positive,arousing distractors impair rapid target perception

Emotional stimuli tend to capture and hold attention more than non-emotional stimuli do. Aversive pictures have been found to impair perception of visual targets even after the emotional information has disappeared. The benefits of such interlinked emotion and attention systems have sometimes been discussed within an evolutionary framework, with a survival advantage attributed to early detection of threatening stimuli. However, consistent with recent suggestions that attention is drawn to arousing stimuli regardless of whether they are positive or negative, the current investigation found that erotic distractors—generally rated as both pleasing and arousing—consistently elicited a transient “emotion-induced blindness” similar to that caused by aversive distractors (Experiment 1). This effect persisted despite performance-based monetary incentives to ignore the distractors (Experiment 2), and following attentional manipulations that reduced interference from aversive images (Experiment 3). The findings indicate that positively arousing stimuli can spontaneously cause emotion-induced deficits in visual processing, just as aversive stimuli can.     

I am going to gag: Disgust cognitions in spider and blood–injury–injection fears

There is mounting evidence that disgust plays an important role in certain anxiety disorders, yet little is known about disgust's cognitive component. The current study introduces a measure of cognitions associated with disgust and contamination to assess the role of disgust-specific primary and secondary appraisals in phobic responding. A multi-modal assessment of blood–injury–injection (BII) and spider phobia was conducted using BII (N=29) and spider (N=30) fearful groups, and a non-fearful control group (N=30). The Disgust Cognitions scale showed good reliability and validity, and distinguished among the groups. For example, relative to the other groups, the spider fear group reported higher disgust cognitions following presentation of a live spider, whereas the BII Fear group reported higher disgust cognitions following a surgery video. Moreover, the scale was associated with multiple phobic indicators (behavioural avoidance, subjective distress, symptom endorsement), suggesting cognitions may be critical to understanding how disgust contributes to anxiety disorders.     

Knowledge of Memory Aging Across the Lifespan

ABSTRACT. The authors examined knowledge of normal and pathological memory aging in a lifespan sample of 198 individuals who ranged in age from 13 to 88 years. Participants completed the Knowledge of Memory Aging Questionnaire (Cherry, Brigman, Hawley, & Reese, 2003). The authors hypothesized that high school students would be less knowledgeable about memory aging issues than college students, middle-aged, and community-dwelling older adults. Consistent with this hypothesis, response accuracy was lower for high school students compared to their older counterparts. Follow-up analyses revealed that high school students’ responses to a subset of questions that tap ageist views of adult cognition were less accurate than the other age groups, implying a response bias toward stereotypical images of memory aging. Implications for research and the design of instructional materials to increase people's knowledge about normative changes in adult cognition are discussed.     

Bar graphs depicting averages are perceptually misinterpreted: The within-the-bar bias

Perhaps the most common method of depicting data, in both scientific communication and popular media, is the bar graph. Bar graphs often depict measures of central tendency, but they do so asymmetrically: A mean, for example, is depicted not by a point, but by the edge of a bar that originates from a single axis. Here we show that this graphical asymmetry gives rise to a corresponding cognitive asymmetry. When viewers are shown a bar depicting a mean value and are then asked to judge the likelihood of a particular data point being part of its underlying distribution, viewers judge points that fall within the bar as being more likely than points equidistant from the mean, but outside the bar--as if the bar somehow "contained" the relevant data. This "within-the-bar bias" occurred (a) for graphs with and without error bars, (b) for bars that originated from both lower and upper axes, (c) for test points with equally extreme numeric labels, (d) both from memory (when the bar was no longer visible) and in online perception (while the bar was visible during the judgment), (e) both within and between subjects, and (f) in populations including college students, adults from the broader community, and online samples. We posit that this bias may arise due to principles of object perception, and we show how it has downstream implications for decision making.     

Who am I to judge? Self-disgust predicts less punishment of severe transgressions

Although recent research has shown that experimentally induced disgust and the personality trait of disgust sensitivity is associated with more severe moral decisions, no study to date has examined how disgust, experienced specifically toward the self, influences morally relevant decisions. Participants (n = 109) in the present study completed a measure of self-disgust, disgust sensitivity, and depressive symptoms and then evaluated nonoffenses, moderate offenses, and severe offenses with regard to level of disgust and punishment deserved. The results showed that self-disgust significantly predicted more disgust and punishment ratings of nonoffenses when controlling for individual differences in both depressive symptoms and disgust sensitivity. In contrast, self-disgust significantly predicted less disgust and punishment ratings of severe offenses when controlling for individual differences in depressive symptoms and disgust sensitivity. The implications of these findings for further conceptualizing how the heterogeneous construct of disgust operates in the moral domain are discussed.     

A simple proximity heuristic allows tracking of multiple objects through occlusion

Moving objects in the world present a challenge to the visual system, in that they often move in and out of view as they are occluded by other surfaces. Nevertheless, the ability to track multiple objects through periods of occlusion is surprisingly robust. Here, we identify a simple heuristic that underlies this ability: Pre- and postocclusion views of objects are linked together solely by their spatial proximity. Tracking through occlusion was always improved when the postocclusion instances reappeared closer to the preocclusion views. Strikingly, this was true even when objects?? previous trajectories predicted different reappearance locations and when objects reappeared ??too close,?? from invisible ??slits?? in empty space, rather than from more distant occluder contours. Tracking through occlusion appears to rely only on spatial proximity, and not on encoding heading information, likely reappearance locations, or the visible structure of occluders.     

Enhancing Treatment Integrity Maintenance Through Fading with Indiscriminable Contingencies

School psychologists are often asked to develop treatment to remediate students’ academic skills or social behavior problems. When teachers implement treatment recommendations with high levels of treatment integrity, students benefit. Treatment integrity has been enhanced by use of direct training, performance feedback, and negative reinforcement procedures. Still, maintenance of treatment integrity has received limited systematic inquiry. This study investigated maintenance of treatment integrity over time by utilizing a systemic fading procedure with indiscriminable contingencies. The results showed that the teachers continued to implement treatment protocols at a high level after performance feedback was faded. Students also fared better when treatment integrity was high.

Abstract

This paper raises a question about one of the principal assumptions of some neo-Thomist approaches to divine action: that it is always inappropriate to conceive of God as one agent among others. To do so, it is claimed, is to reduce God's position from that of Creator to that of a creature. However, this seems an odd position to take in light of the Incarnation. I suggest that after the divine humility displayed in the Incarnation, conceiving God as one agent among others is not as theologically problematic as it is initially represented by some neo-Thomists.
