Cognitive treatment of pathological gamblers

This study evaluates the efficacy of a cognitive treatment for pathological gambling. Five pathological gamblers were treated in a multiple baseline across subjects design. Cognitive correction targeted the erroneous perceptions towards the notion of randomness. Four subjects reported a clinically significant decrease in the urge to gamble, an increase in their perception of control, and no longer met the DSM-IV criteria for pathological gambling. Therapeutic gains were maintained at the 6 month follow-up. Results suggest that cognitive therapy targeting the misconception of the notion of randomness is a promising treatment for pathological gambling, a refractory disorder to most therapeutic interventions.     

On how task-contingent rewards,individual differences in causality orientations,and imagery abilities are related to intrinsic motivation and performance

This study explored how causality orientations, individual differences in imagery, and reward contingency are related to performance and intrinsic motivation. Cognitive evaluation theory, as applied to both causality orientation and reward contingency, was used to make predictions about the effects of internal or external events perceived as being autonomy supportive or controlling. In the light of the fact that task-contingent rewards must be salient to undermine intrinsic motivation and performance, one can suppose that high imagery may increase the controlling aspects of task-contingent rewards. Moreover, research now indicates that vegetative activation correlates with levels of imagined effort, and that high imagery capabilities enhance performance in motor skills. The main purpose of this study was to contribute some arguments for imagery and reward interaction effects on intrinsic motivation and performance. As predicted, autonomy-oriented subjects reported more interest and intrinsic motivation, and exhibited better performance than did control-oriented individuals. Similar differences were observed in favour of high-imagery individuals. Moreover, the effects of imagery were not only subject to an interaction between imagery and causality orientation, but also between imagery and reward contingency. The links between these variables are discussed in the framework of both Carver and Scheier's (1981) motivational control theory, and Deci and Ryan's (1985a) cognitive evaluation theory. © 1998 John Wiley & Sons, Ltd.     

Understanding pregnant women's decision making concerning prenatal screening

OBJECTIVE: This study is aimed at enhancing understanding prenatal screening decision making through testing a hypothesized decision model based on decision theory and health behavior theory. DESIGN: We obtained questionnaires from 1,666 pregnant women who were offered prenatal screening for Down's syndrome. Path analysis (using LISREL) resulted in a final model with reasonable model fit, which was verified by split-sample cross-validation. MAIN OUTCOME MEASURES: These included perceived probability, perceived severity, attitude toward termination, response efficacy, attitude toward prenatal screening, subjective norm, child-related anxiety, and intention to undergo prenatal screening. RESULTS: Attitude toward termination of pregnancy, perceived test efficacy, and subjective norm regarding the desirability of having prenatal screening determined a woman's attitude toward having a prenatal test. Anxiety was influenced by perceived risk and perceived severity of having a child with Down's syndrome, and by subjective norm, but this appeared to be a weak predictor of intention to test. Pregnant women with a positive attitude toward prenatal screening, and who perceived a subjective norm in favor of undergoing prenatal screening, showed a greater intention to have prenatal screening done. CONCLUSION: These findings suggest that more attention should be paid toward the values and social context of pregnant women during the counseling process.

‘Liars are less detailed’ …So what? Comparing two recall instructions to detect deception within-subject

Most deception research provides between-subject results (e.g., liars give on average less detailed accounts), which might be of limited value for professionals evaluating credibility on an individual basis. This study examines the optimal instructions of a within-subject multiple recalls strategy to detect deception. A total of 110 participants, divided into a Lie and Truth group, were randomly placed into four interview conditions: two Basic report-everything instructions (1), a Basic recall followed by an Open depth instruction (2), a Basic recall followed by the Verifiability Approach and Information Protocol (3), and two recalls with the Verifiability Approach and Information Protocol (4). All recalls were coded for total details and verifiable details. Group (lie and truth) × Recall (first and second) was only significant in condition 3, with truth tellers providing more verifiable details in the second recall than the first. A simple within-subject decision rule was derived, allowing a 76.9% discrimination rate. Professionals can optimally evaluate credibility using two recalls (Basic recall followed by Verifiability Approach and Information Protocol) and observing the evolution of verifiable details.     

ERP evidence for task modulations on face perceptual processing at different spatial scales

Does the perceptual processing of faces flexibly adapt to the requirements of the categorization task at hand, or does it operate independently of this cognitive context? Behavioral studies have shown that the fine and coarse spatial scales of a face are differentially processed depending on the categorization task performed, thus suggesting that the latter can influence stimulus perception. Here, we investigated the time course of these task influences on perceptual processing by examining the visual N170 face‐sensitive Event‐Related Potential (ERP), while observers categorized faces for their gender and familiarity. Stimuli were full spectrum, or filtered versions that preserved either coarse or fine scale information of the faces. Behavioral results replicated previous findings of a differential processing of coarse and fine spatial scales across tasks. In addition, the N170 amplitude was larger in the Gender task as compared to the Familiarity task for LSF faces exclusively, thus showing that task demands differentially modulated the spatial scale processing on faces. These results suggest that the diagnosticity of scale‐specific cues in categorization tasks can modulate face processing.     

Testing Clinical Intuitions About Barriers to Improvement in Cognitive-Behavioral Therapy for Panic Disorder

Although clinical intuitions influence psychotherapeutic practice and are a rich source of novel hypotheses for research, many remain to be empirically tested. This study evaluates whether clinicians’ beliefs about barriers to progress in cognitive-behavioral therapy (CBT) for panic disorder are supported by data. Data from a randomized-controlled trial comparing CBT to panic-focused psychodynamic psychotherapy (PFPP) for adults with primary panic disorder (N = 161) were used to evaluate 15 factors endorsed by clinicians as impediments to CBT in a recent survey. Panic severity was assessed before, during (at Weeks 1, 5, and 9), and at termination of treatment (Week 12) using the Panic Disorder Severity Scale. Hierarchical linear modeling revealed that none of the perceived barriers were predictive of poor outcome. Contrary to clinicians’ intuitions, dissociation during panic attacks was associated with greater symptomatic improvement in both treatment arms (β = ?0.69, p < .05), above the effect of established predictors. Moderation analyses revealed that when patients had PTSD diagnosed with the Anxiety Disorders Interview Schedule (β = 1.71, p < .05) or less severe panic disorder (β = 0.45, p = .04), they changed more rapidly in CBT than in PFPP. Overall, clinician agreement was inversely related to the strength of a predictor (r = ?.24, p = .39). Although clinical intuitions can be useful as clinical and empirical signals, such beliefs should be critically examined before informing practice. Dialogue between academics and clinicians might be enhanced through research that incorporates input from front-line practitioners.     

Combined Effects of Movement Velocity and Duration on Programming Time: Spijkers (1989) Revisited

The goal of the present study was to determine the combined effects of movement velocity and duration on motor programming. Subjects were submitted to a two-choice reaction time task that could be completed by aiming movements differing in the mean velocity at which they were to be produced as well as by their movement time. The results of the present study indicate that, in each pair of responses used, the responses having the higher mean velocity were initiated faster than those having the lower mean velocity. Contrary to Spijkers' (1989) study, the different movement time pairings did not modify the effect of movement velocity on response programming time. Moreover, the same pattern of results was observed whether or not the subjects were permitted to visually guide their ongoing movement. Thus, Spijkers' proposition, that the type of control one may use to guide an aiming movement needs to be determined before movement initiation can take place, was not confirmed.     

Temporal Aspects of Team Cognition: A Case Study on Concerns Sharing Within Basketball

This case study investigated team cognition in basketball. The focus was on how concerns in a real match situation were shared among teammates and how the sharedness evolved. The activity of five basketball players (M age = 17.60, SD = 0.89) was studied. The data were collected and processed according to a procedure defined for course-of-action analysis (Theureau, 2003). The results indicated that the instances when all the teammates shared the same typical concern were relatively rare, but temporal analysis revealed two kinds of convergence phenomena (simultaneous and progressive). In conclusion, shared understanding emerged within this team as essentially “local sharing of understanding.”
