The efficacy of videotape feedback for enhancing the effects of exposure-based treatment for social anxiety disorder: a controlled investigation

Correcting patients' faulty beliefs concerning social evaluative threats is the hallmark of cognitive-behavioral treatment of social anxiety disorder. The current study examined the efficacy of two videotape feedback procedures as adjuncts to exposure-based treatment. Participants suffering from social phobia (N=77) were randomly assigned to one of four conditions: (a) credible placebo treatment (PLA); (b) exposure + no feedback (EXP); (c) exposure + videotape feedback of performance (PER); or (d) exposure + videotape feedback of audience responses (AUD). Contrary to prediction, the videotape feedback procedures did not enhance the effects of exposure-based treatment. Clinical and theoretical implications are discussed.     

A cybernetic theory of morality and moral autonomy

Human morality may be thought of as a negative feedback control system in which moral rules are reference values, and moral disapproval, blame, and punishment are forms of negative feedback given for violations of the moral rules. In such a system, if moral agents held each other accountable, moral norms would be enforced effectively. However, even a properly functioning social negative feedback system could not explain acts in which individual agents uphold moral rules in the face of contrary social pressure. Dr. Frances Kelsey, who withheld FDA approval for thalidomide against intense social pressure, is an example of the degree of individual moral autonomy possible in a hostile environment. Such extreme moral autonomy is possible only if there is internal, psychological negative feedback, in addition to external, social feedback. Such a cybernetic model of morality and moral autonomy is consistent with certain aspects of classical ethical theories.     

Auditory feedback control in adults who stutter during metronome-paced speech I. Timing Perturbation

PurposeThis study determined whether adults who stutter (AWS) exhibit deficits in responding to an auditory feedback timing perturbation, and whether external timing cues, which increase fluency, attenuate any disruptions due to altered temporal auditory feedback.MethodsFifteen AWS and sixteen adults who do not stutter (ANS) read aloud a multisyllabic sentence either with normal pacing or with each syllable paced at the rate of a metronome. On random trials, an auditory feedback timing perturbation was applied, and timing responses were compared between groups and pacing conditions.ResultsBoth groups responded to the timing perturbation by delaying subsequent syllable boundaries, and there were no significant differences between groups in either pacing condition. Furthermore, no response differences were found between normally paced and metronome-paced conditions.ConclusionThese findings are interpreted as showing that 1) AWS respond normally to pure timing perturbations, and 2) metronome-paced speech has no effect on online speech timing control as assessed in the present experiment.     

The influence of mental toughness on responses to feedback in snooker: A real-time examination

Two experiments investigated whether mental toughness (MT) is associated with the ability to respond to and/or overcome unwanted information during real-time sport performance. Participants were male snooker players ranging from club to professional level, and MT was measured using the MTQ48 (Clough et al., 2002). In experiment 1, players performed five break-off shots and received deceptive feedback (either positive or negative) from the researcher about their performance relative to other players. Then they performed another five break-offs. Results showed a significant decline in performance following feedback, but no interaction with the nature of feedback or MT variables. In experiment 2, feedback was delivered by a coach and yielded a significant effect on performance. Specifically, negative feedback improved performance while positive feedback impaired performance. The Life Control subscale of the MTQ48 was a significant covariate. The results suggest that negative feedback, delivered constructively by a respected figure, may act as a catalyst for performance enhancement in snooker and that this is moderated by MT.     

THE EFFECTS OF SELF-MONITORING AND SUPERVISOR FEEDBACK ON STAFF PERFORMANCE IN A RESIDENTIAL SETTING

We evaluated the effects of a self-monitoring procedure to increase staff on-task behavior and adherence to scheduled activities. Self-monitoring involved the use of activity cards that staff members completed and carried with them to assist in determining the activities for which they were responsible at any given time. Increases in both on-schedule and on-task behavior resulted. Supervisor feedback was subsequently added because some staff members did not maintain consistently high levels of performance. Generalization data indicated that staff members implemented the procedure during evening hours without specific programming. The advantages and limitations of using a self-monitoring procedure for improving performance of staff members in residential settings are discussed.     

ASSESSING AND IMPROVING CHILD CARE: A PERSONAL APPEARANCE INDEX FOR CHILDREN WITH AUTISM

An index of children's physical appearance and personal care was developed and used to assess youngsters with autism who lived (a) at home, (b) in an established group home, (c) in new group homes, and (d) in a large institution. Subsequently, a multiple baseline design across participants documented major changes in personal appearance and cleanliness when children moved from an institution to community-based, family-style group homes. Finally, data-based feedback generated by the appearance index was used as a training tool enabling group home staff to further improve child appearance. This research demonstrates how an evaluation instrument can be used to obtain comparative data, measure some effects of different residential placements, and provide ongoing feedback to caregivers to promote high standards of personal care among persons with severe developmental disabilities.

Counterfactual Evaluation of Outcomes in Social Risk Decision-Making Situations: The Cognitive Developmental Paradox Revisited

We report a study that examined the existence of a cognitive developmental paradox in the counterfactual evaluation of decision-making outcomes. According to this paradox adolescents and young adults could be able to apply counterfactual reasoning and, yet, their counterfactual evaluation of outcomes could be biased in a salient socio-emotional context. To this aim, we analyzed the impact of health and social feedback on the counterfactual evaluation of outcomes in a laboratory decision-making task involving short narratives with the presence of peers. Forty risky (e.g., taking or refusing a drug), forty neutral decisions (e.g., eating a hamburger or a hotdog), and emotions felt following positive or negative outcomes were examined in 256 early, mid- and late adolescents, and young adults, evenly distributed. Results showed that emotional ratings to negative outcomes (regret and disappointment) but not to positive outcomes (relief and elation) were attenuated when feedback was provided. Evidence of development of cognitive decision-making capacities did also exist, as the capacity to perform faster emotional ratings and to differentially allocate more resources to the elaboration of emotional ratings when no feedback information was available increased with age. Overall, we interpret these findings as challenging the traditional cognitive developmental assumption that development necessarily proceeds from lesser to greater capacities, reflecting the impact of socio-emotional processes that could bias the counterfactual evaluation of social decision-making outcomes.     

Audio Feedback with Reduced Self-focus as an Intervention for Social Anxiety: An Experimental Study

Background and Objectives: Socially anxious individuals tend to underestimate their performance largely due to attentional bias. Video and audio feedback (AF) with cognitive preparation (CP) have shown to improve socially anxious individuals′ evaluation of their performance in previous studies. In the present study, it was hypothesized that one of the three steps in CP, reduced self-focus (RS), is sufficient to cause an improved voice evaluation after AF. This was tested in a single-session randomized controlled experiment. Method: Forty-one socially anxious participants were asked to give a speech, then to listen to and evaluate a taped recording of their performance. Half of the sample were instructed to reduce their self-focus prior to AF, the rest received AF only. RS involved asking participants to listen to the audio recording as though they were listening to a stranger. Generalization effects were assessed by a second speech. Results: AF with RS led to more improved voice evaluations than AF-only after the first speech, and the effects remained in the evaluation of the second speech. More positive speech evaluations were associated with corresponding reductions of performance anxiety.Limitations: small sample, analogue study. Conclusion: One component of cognitive preparation—(RS)—appears to be sufficient to cause significant effects on voice evaluation in socially anxious individuals. If the results are replicated in clinical samples, AF with RS may be a promising intervention in the treatment of social anxiety.
