Reducing speech disfluencies during public speaking using brief habit reversal

Recent research has evaluated the effects of brief habit reversal, consisting of either awareness training (AT) and competing response training (Mancuso & Miltenberger, 2016), or AT alone (Spieler & Miltenberger, 2017) in reducing speech disfluencies during public speaking. Although both formats of brief habit reversal reduced rates of speech disfluencies, results suggested that teaching a competing response (CR) may produce better outcomes. We aimed to replicate and extend those studies by evaluating the effects of AT and instructing the use of a CR (a silent pause) on rates of speech disfluencies and CRs during public speaking. Following training, all 4 participants demonstrated a reduction of speech disfluencies, and 1 participant demonstrated moderate levels of CRs when giving a speech in front of both a single experimenter and small audience. For 1 participant, generalized effects were demonstrated when presenting in front of a class.     

Awareness training reduces college students' speech disfluencies in public speaking

Recent research suggests that a modified habit reversal procedure, including awareness training alone or combined with competing response training, is effective in decreasing speech disfluencies for college students. However, these procedures are potentially lengthy, sometimes require additional booster sessions, and could result in covariation of untargeted speaker behavior. We extended prior investigations by evaluating awareness training as a sole intervention while also measuring collateral effects of treatment on untargeted filler words and rate of speech. We found awareness training was effective for all participants without the use of booster sessions, and covariation between targeted filler words and secondary dependent variables was idiosyncratic across participants.     

The efficacy of remote video-based behavioral skills training and awareness training on public speaking performance

This study evaluated the efficacy of (a) remote video-based behavioral skills training (BST) with added speech outlines on teaching public speaking behaviors and (b) remote video-based awareness training (AT) on speech-disfluency rates. A multiple-baseline design across speech behaviors was used to evaluate the training. Remote video-based BST and AT were effective at teaching public speaking behaviors and reducing speech disfluencies, respectively, for both participants. In addition, performance generalized to increased audience size. Although expert ratings of perceived public speaking effectiveness improved following BST, the ratings did not improve and some worsened following AT. Both participants reported satisfaction with video-based BST and AT. One participant reported greater comfort, confidence, overall ability, and less anxiety as a public speaker following BST. Both participants reported greater improvements in those categories following AT. Our results suggest that public speaking behaviors can be taught using remote video-based BST and speech disfluencies can be reduced using remote video-based AT.     

Spaced Retrieval Enhances Memory in Older Adults with Probable Alzheimer's Disease

We used the spaced retrieval method to improve recall of everyday objects in older adults with probable Alzheimer's Disease. Three training sessions were administered on alternate days over a week. On each training trial, participants selected a designated object from an array of items at increasingly longer retention intervals. Implicit and explicit memory for the target item was assessed after each session. Results indicated that spaced-retrieval training enhanced retention of the target item within and across sessions for all participants. Implications of these findings for current views on memory interventions for cognitively impaired older adults are discussed. affiliated with the Menorah Park Center for the Aging     

Impact of Stress Reduction Interventions on Hostility and Ambulatory Systolic Blood Pressure in African American Adolescents

This study examined the impact of breathing awareness meditation (BAM), life skills (LS) training, and health education (HE) interventions on self-reported hostility and 24-hour ambulatory blood pressure (ABP) in 121 African American (AA) ninth graders at increased risk for development of essential hypertension. They were randomly assigned to BAM, LS, or HE and engaged in intervention sessions during health class for 3 months. Before, after, and 3 months following intervention cessation, self-reported hostility and 24-hour ABP were measured. Results indicated that between pre- and postintervention, BAM participants displayed significant reductions in self-reported hostility and 24-hour systolic ABP. Reductions in hostility were significantly related to reductions in 24-hour systolic ABP. Between postintervention and follow-up, participants receiving LS showed a significant reduction in hostility but not in 24-hour ABP. Significant changes were not found for the HE group in 24-hour ABP or self-reported hostility, but these change scores were significantly correlated. The implications of the findings are discussed with regard to behavioral stress reduction programs for the physical and emotional health of AAs.     

Urgent and non-urgent takeovers during conditional automated driving on public roads: The impact of different training programmes

Supplying training to drivers that teaches them about automated driving and requests to intervene may help them to build and maintain a mental representation of how automation works and thereby improve takeover performance. We aimed to investigate the effect of different types of training programmes about the functioning of automated driving on drivers’ takeover performance during real driving. Fifty-two participants were split into three groups for training sessions: paper (short notice), video (3-minute tutorial) and practice (short drive). After the training, participants experienced automated driving and both urgent and non-urgent requests to intervene in a Wizard-of-Oz vehicle on public roads. Participants’ takeover time, visual behaviour, mental workload, and flow levels during the requests to intervene were assessed. Our results indicated that in urgent circumstances, participants’ takeover response times were faster in the practice training condition compared to the other training conditions. Nevertheless, the practice training session did not present any other positive effect on drivers’ visual behaviour. This could indicate that prior training, particularly when reinforcing drivers' motor skills, improved their takeover response time at the latest motor stages rather than in the early sensory states. In addition, the analysis of in-vehicle videos revealed that participants’ attention was captured in the first place by the in-vehicle human-machine interface during the urgent request to intervene. This highlights the importance for designers to display information on the HMI in an appropriate way to optimise drivers’ situation awareness in critical situations.     

Encounter group counsellor training with pre-service industrial psychologists: A pilot study

This study explored the efficacy of an encounter group counsellor training protocol to prepare pre-service industrial-organisational (I-O) psychologists as workplace counsellors. The participants included 48 master’s degree students enrolled for I-O professional education at a South African university over the span of two years (female = 59%, aged 23 to 30 years, white = 79% and Afrikaans speaking = 70%). They were engaged in an encounter group training process as part of their professional preparation. Qualitative impressions on the students’ experiences impacting on their intra-and interpersonal awareness were gathered after the training using a structured observation design. The data were thematically analysed and the findings indicated the participants portrayed a higher sense of inter-and intrapersonal awareness following the encounter group training. Encounter group experiences might be of added value in the training of future I-O psychologists for interpersonal awareness.     

Usability and Utility of a Computerized Cognitive-Behavioral Self-Help Program for Public Speaking Anxiety

This study describes the use of a cognitive-behavioral computer-administered self-help program with minimal therapist contact for public speaking anxiety. Participants (N = 10) with social phobia, as measured by a structured clinical interview, completed the self-help program in an open clinical trial. The program was delivered via a CD-ROM during individual sessions at an outpatient clinic, including 4 sessions of psychoeducation/cognitive therapy and 4 sessions of exposure therapy using a virtual audience presented on a computer screen. A therapist was available in another room to answer questions and to debrief for up to 10 minutes after each session. Participants completed standardized self-report questionnaires assessing social anxiety at pretreatment, posttreatment, and 3-month follow-up. Participants also completed measures of computer usability. Results showed decreases on all self-report measures of social anxiety from pre- to posttreatment, which were maintained at follow-up (n = 8). Participants also reported that they were satisfied with treatment, that they felt improved after treatment, and that the computer program was user-friendly. This study provides preliminary evidence that a computer-administered cognitive-behavioral-based program that includes minimal therapist contact may reduce public speaking anxiety and suggests that further research with a controlled design is needed.     

National attitudes towards mental health treatment: the importance of research evidence

Most conceptualizations of evidence-based practice view it as a “three legged stool” consisting of: the use of best available research evidence, clinical expertise, and client preferences. Although empirical evidence and clinical expertise have received greater empirical attention, relatively little research has systematically explored client preferences. The present study analyzed self-reported treatment preferences for various clinical and non-clinical presentations. Adult participants (n = 1262) residing in the United States were presented with diagnostic vignettes and rated their relative preferences among 5 treatment variables, including: use of an empirically supported treatment (EST), quality of the client–therapist relationship, therapist empathy, therapist experience, and client speaking for the majority of therapy sessions. Results indicated that participants endorsed significant preference for receiving an EST over other treatment variables for all clinical disorders, with effect sizes ranging from small to large depending on the diagnosis. There was slightly greater variability in treatment preferences for non-clinical issues, though participants generally reported greater preference for receiving an EST. Follow-up questions provided further evidence for EST preferences. The implications of these results are discussed.     

Training Public School Special Educators to Implement Two Functional Analysis Models

The purpose of this study was to investigate the efficacy and efficiency of a training package to teach public school special educators to conduct functional analyses of challenging behavior. Six public school educators were divided into two cohorts of three and were taught two models of functional analysis of challenging behavior: traditional and trial-based functional analysis. The effect of the training package on functional analysis implementation was evaluated using multiple-baseline designs across participants for each functional analysis model. The sequence of functional analysis models taught was counterbalanced across cohorts. Following the training package, all participants reached 100 % implementation fidelity during role-plays and classroom sessions with students, and maintained high fidelity at follow-up role-play sessions. Data on training duration, trials to criterion, and social validity revealed that trial-based functional analysis training had a shorter duration and was rated as the more favorable functional analysis model.     

Targeting the probability versus cost of feared outcomes in public speaking anxiety

Cognitive-behavioral theory suggests that social phobia is maintained, in part, by overestimates of the probability and cost of negative social events. Indeed, empirically supported cognitive-behavioral treatments directly target these cognitive biases through the use of in vivo exposure or behavioral experiments. While cognitive-behavioral theories and treatment protocols emphasize the importance of targeting probability and cost biases in the reduction of social anxiety, few studies have examined specific techniques for reducing probability and cost bias, and thus the relative efficacy of exposure to the probability versus cost of negative social events is unknown. In the present study, 37 undergraduates with high public speaking anxiety were randomly assigned to a single-session intervention designed to reduce either the perceived probability or the perceived cost of negative outcomes associated with public speaking. Compared to participants in the probability treatment condition, those in the cost treatment condition demonstrated significantly greater improvement on measures of public speaking anxiety and cost estimates for negative social events. The superior efficacy of the cost treatment condition was mediated by greater treatment-related changes in social cost estimates. The clinical implications of these findings are discussed.     

A Self-Modeling Intervention for High School Students with Public Speaking Anxiety

ABSTRACT

The study investigated the effectiveness of self-modeling as an intervention for public speaking anxiety. The participants were six high school students with elevated levels of self-reported public speaking anxiety. Students presented public speeches to randomly selected peer audiences. Direct observations measured the behavioral manifestations of public speaking anxiety. In the intervention phase, students viewed self-modeling videotapes that were edited to remove speech dysfluencies and behavioral symptoms of speech anxiety. The self-modeling tapes depicted only adaptive, exemplary behavior with an edited-in audience feature making it appear that the students were producing a fluent speech to an audience of their peers. All of the participants evidenced substantial decreases in behavioral symptoms of speech anxiety and these changes were maintained throughout follow-up. The range of the participants' effect sizes was 2.7 to 4.9. Self-report measures of state anxiety and confidence as a speaker were used to assess additional effects of treatment. For all participants, there were also substantial decreases in self-reported public speaking anxiety and state anxiety from baseline to follow-up. A post-treatment interview revealed high social validity and self-reported generalization of treatment.     

An Emotion Regulation Treatment for Young People With Complex Substance Use and Mental Health Issues: A Case-Series Analysis

Individuals accessing treatment within the youth alcohol and other drug (AoD) sector represent a highly vulnerable population who present with complex patterns of substance use and mental health comorbidity. Current treatments often fail to address this complexity. Emotion regulation (ER) has been identified as a promising transdiagnostic treatment target for this population of young people. The current study aimed to investigate the acceptability and feasibility of an adjunct ER intervention, ERIC (Emotion Regulation and Impulse Control) in young people receiving AoD treatment at a residential rehabilitation service. A mixed methods case series design was utilized. Ten participants aged between 16–20 years old completed 4–6 sessions of ERIC as an adjunct to their existing residential treatment. Participants undertook a post intervention feedback session and completed a number of self-report measures of ER, depression and anxiety at baseline and 2 weeks after receiving ERIC. Qualitative feedback from young people following the delivery of ERIC was positive, and suggested that ERIC was a viable and useful intervention. Participants reported that the components of ERIC, which involved metaphors and experiential exercises, were particularly beneficial and memorable. Pre-post measures indicated that 60% of the young people had both reliable and clinically significant reductions in overall emotion dysregulation, while reliable and clinically significant reductions in depression and anxiety were observed in 50% and 60% of participants respectively. Results support the acceptability of ERIC for this cohort of young people with complex substance use and mental health needs. Furthermore, these findings support the viability of delivering flexible and adjunctive ER treatments to young people seeking AoD treatment.     

Working memory capacity and strategy use

In this study, we examine the role of strategy use in working memory (WM) tasks by providing short-term memory (STM) task strategy training to participants. In Experiment 1, the participants received four sessions of training to use a story-formation (i.e., chaining) strategy. There were substantial improvements from pretest to posttest (after training) in terms of both STM and WM task performance. Experiment 2 demonstrated that WM task improvement did not occur for control participants, who were given the same amount of practice but were not provided with strategy instructions. An assessment of participants' strategy use on the STM task before training indicated that more strategic participants displayed better WM task performance and better verbal skills. These results support our hypothesis that strategy use influences performance on WM tasks.     

Controlling competitive anger among male soccer players

Abstract

This study examined the effectiveness of anger awareness training (i.e., self-monitoring) and role-playing (i.e., modeling and behavioral rehearsal) in reducing participants’ angry behavior and angry feelings. Male participants (N = 57) from intact soccer teams were randomly assigned to a role-playing, an anger awareness, or a control group. Pretreatment anger scores indicated that all three groups exhibited similar anger dispositions before the study began. Following pretreatment assessment, angry behavior and self-reported anger were observed and measured during a 15-game round-robin soccer season. Analyses revealed that although angry feelings remained consistent across the duration of the study, the role-playing group was more effective than both the anger awareness and control groups in controlling angry behavior. Findings indicate that although the use of anger awareness and role-playing interventions can reduce angry behavior, the role-playing intervention was a more effective method.     

Training educators to implement functional analyses

The present study examined the use of an instructional workshop for training educators to conduct functional analyses. Results indicated that 2 of 3 participants met the accuracy criterion following group training, whereas 1 participant required direct verbal feedback. During generalization probes, one participant accurately conducted sessions with a student in her classroom.     

EFFECTS OF VERBAL REPRIMANDS ON TARGETED AND UNTARGETED STEREOTYPY

Results of brief functional analyses indicated that motor and vocal stereotypy persisted in the absence of social consequences for five participants diagnosed with autism spectrum disorder (ASD). Subsequently, effects of a stimulus control procedure involving contingent reprimands for each participant's higher probability (targeted) stereotypy were evaluated. Results indicated that contingent verbal reprimands (i) decreased the targeted stereotypy for all five participants, (ii) decreased the untargeted stereotypy for two of five participants, and (iii) increased the untargeted stereotypy for one of five participants. Although response suppression was not achieved for any participant, three participants maintained low levels of the target stereotypy with one or two reprimands during 5‐min sessions. Furthermore, two of those participants maintained near‐zero levels of motor and vocal stereotypy during 10‐min sessions. These findings suggest that signaled verbal reprimands may be a practical intervention for reducing stereotypy in some children with ASD. Some limitations of the findings and areas of future research are briefly discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Training for paraprofessional counsellors: Evaluating the meaning and impact of a common factors approach

A group of 12 people participated in a short (40 hours) counselling training programme for paraprofessional counsellors, which emphasised the importance of common factors in accounting for therapeutic effectiveness. The general framework, language and skills of a brief, solution‐focused approach was used as a means of translating the theoretical/conceptual ideas of the common factors model into specific counsellor behaviours and also to provide structure and focus for counselling sessions. A pluralist methodology was employed to assess the personal meaning of the training for participants and the impact of the training on the development of counselling skills and awareness. Results indicated the training impacted positively on the development of counselling skills and ability to handle difficult client behaviours but less so on personal values and ability to deal with process issues. The majority of participants believed the training contributed positively toward their personal development.     

SOCIAL SKILLS TRAINING WITH CHILDREN: PROCEED WITH CAUTION

Three learning disabled children, selected on the basis of peer sociometric ratings and teacher referral, received social skills training. A group training procedure consisting of coaching, modeling, behavior rehearsal, and feedback was used to teach children the target behaviors of eye contact and appropriate verbal responses. A multiple baseline analysis across target behaviors was used to demonstrate treatment effectiveness on role-play scenes trained during treatment sessions. Duration of speech was measured as an untrained, corollary measure. The following measures were also obtained during baseline, posttreatment, and 1-mo follow-up for the experimental subjects and three control subjects: (a) performance on role-play scenes not trained during treatment sessions; (b) behavioral observations in a free play setting, and (c) sociometric ratings. In addition, the trained and untrained role-play scenes were administered by novel experimenters following treatment. The results indicated that socially unskilled, learning disabled children can be taught to respond appropriately to role-play situations. However, improved performance did not generalize to the natural school setting and treatment did not effect ratings of peer acceptance. The implications of these findings for future social skills training with children are discussed.     

Posttraumatic Stress Disorder and Chronic Pain Arising from Motor Vehicle Accidents: Efficacy of Interoceptive Exposure Plus Trauma-Related Exposure Therapy

Preliminary data are presented on the pattern of treatment response of combining interoceptive exposure (IE) with trauma-related exposure therapy (TRE) in five female patients with posttraumatic stress disorder (PTSD) and comorbid chronic musculoskeletal pain originating from motor vehicle accidents. Treatment consisted of four sessions of IE followed by eight sessions of TRE. Four participants reported a reduction in PTSD symptoms after completing treatment, and three no longer met diagnostic criteria for PTSD. Although both interventions were associated with reductions in PTSD symptoms, TRE was associated with greater reductions in PTSD symptoms than IE and was particularly effective at reducing avoidance. IE was associated with larger reductions in anxiety sensitivity than TRE. Pain symptoms lessened slightly during IE and then worsened following TRE. Anxiety decreased after completing treatment, whereas panic and depressive symptoms responded less so. Three individuals completed a 3-month follow-up assessment. There was no change in their PTSD diagnostic status, and all experienced a slight loss of pre–post gains, particularly involving the return of pain. Clinical and research implications are discussed.
