The development of the virtual reality system for the treatment of the fears of public speaking.

The fear of public speaking is a kind of social phobias. The patients having the fear of public speaking show some symptoms like shame and timidity in the daily personal relationship. They are afraid that the other person would be puzzled, feel insulted, and they also fear that they should be underestimated for their mistakes. For the treatment of the fear of public speaking, the cognitive-behavioral therapy has been generally used. The cognitive-behavioral therapy is the method that makes the patients gradually experience some situations inducing the fears and overcome those at last. Recently, the virtual reality technology has been introduced as an alternative method for providing phobic situations. In this study, we developed the public speaking simulator and the virtual environments for the treatment of the fear of public speaking. The head-mounted display, the head-tracker and the 3 dimensional sound system were used for the immersive virtual environment. The imagery of the virtual environment consists of a seminar room and 8 virtual audiences. The patient will speak in front of these virtual audiences and the therapist can control motions, facial expressions, sounds, and voices of each virtual audience.

Conditioning theory: a model for the etiology of public speaking anxiety?

To study the etiology of public speaking anxiety (speech phobia), 30 Ss with the fear of public speaking, and 24 controls without this fear were asked about past public speaking experiences, their beliefs about the main reason for their phobia, and their concerns in the feared situation. All speech phobics met the DSM-III-R criteria for social phobia. Results showed that traumatic external events, vicarious and informational learning--the causes for phobia that fit in best with Rachman's conditioning theory--were notably uncommon among these phobics, who attributed their fear most often to panic attacks. Yet it was not clear whether panic attacks were causes or consequences of phobia.

An instrument to assess self-statements during public speaking: scale development and preliminary psychometric properties.

Public speaking is the most commonly reported fearful social situation. Although a number of contemporary theories emphasize the importance of cognitive processes in social anxiety, there is no instrument available to assess fearful thoughts experienced during public speaking. The Self-Statements During Public Speaking (SSPS) scale is a 10-item questionnaire consisting of two 5-item subscales, the "Positive Self-Statements" (SSPS-P) and the "Negative Self-Statements" subscale (SSPS-N). Four studies report on the development and the preliminary psychometric properties of this instrument.

[Are psychophysiologic changes in the "public speaking" paradigm an expression of emotional stress?].

Public Speaking is often used to induce anxiety. The emotional stress elicited by the anticipation of delivering a public speech, however, is usually confounded with the mental stress of speech preparation. In order to separate the effects of the emotional from those of the mental stress factor, only half of the subjects were informed about the topic of the speech at the beginning of the anticipation period, whereas the other half were told about the topic at a later time. In a pilot study, the effects of this variation were tested under a condition in which the subjects were told that the speech would be videotaped as an anxiety-provoking and under an emotionally neutral control condition. The main experiment involved an additional condition with a simulated audience designed to intensify the impact of the emotional stress component ("strong anxiety"). Self-reports on present state and cardio-vascular and electrodermal responses were measured in n = 12 subjects in both studies. Knowledge of the speech topic did not affect the subjective anxiety-inducing effects of public speaking. Physiologically arousing effects, however, could be shown without knowledge of the topic only in some variables and only under the "strong anxiety"-provoking condition. In studying public speaking anxiety, confounding with the mental stress of speech preparation should therefore be avoided and a more differentiated interpretation of the physiological effects should be made.

Cardiovascular and neuroendocrine adjustment to public speaking and mental arithmetic stressors.

In this study, we evaluated cardiovascular, neuroendocrine, and psychological adjustment to repeated presentations of a public speaking and a mental arithmetic task. Brief versions of mental arithmetic tasks have been used widely in previous reactivity studies, and growing attention to more socially salient tasks has led to the increased use of public speaking tasks. However, psychophysiological adjustment during extended and repeated exposure to these tasks has not been delineated. In the present study, 52 healthy men worked on three 8-min presentations of public speaking and of mental arithmetic in a repeated measure design. Both tasks produced substantial cardiovascular, adrenocorticotropic hormone, and cortisol responses; public speaking produced greater changes. Repeated presentations of public speaking produced a stable pattern of cardiac activation, whereas repetitions of the mental arithmetic initially produced large cardiac responses that changed to a more vascular tonus across task periods. Both tasks increased negative moods. However, correlations between the endocrine, cardiovascular, and negative moods were significant only during the public speaking stressor. The public speaking task is a socially relevant experimental protocol for studying reactivity in the laboratory setting and elicits relatively high, stable, and homogeneous responses.

Simulated public speaking as a model of clinical anxiety.

Normal male volunteers took single acute doses of either diazepam or placebo under double-blind conditions in three simulated public speaking experiments. Measures of palmar sweating and subjective anxiety showed that anticipation of speaking in public increased anxiety relative to baseline and prestress conditions, and performance of public speaking further increased anxiety. A dose-related anxiolytic effect of diazepam on subjective anxiety supported the model's clinical relevance. Moreover, the intensity of the subject's public speaking phobia predicted both degree of prestress anxiety relief from 10 mg diazepam and overall anxiety level, regardless of medication, throughout the experimental session. A measure of traditionalism predicted placebo and 5 mg diazepam response during prestress: As in previous clinical trials, high traditionalism scorers reported more relief from placebo, whereas low scorers showed more relief from diazepam.

Training public-speaking behavior: an experimental analysis and social validation.

The effect of an instructional package on public-speaking behaviors was analyzed in two experiments. The instructional package was designed to teach public-speaking trainees to look at the audience, make gestures, and perform a number of speaking behaviors. The results of Experiment I, with a university student serving as the trainee, showed that the percentage of each category of public-speaking target behavior increased only after the instructional package was introduced for that category. The results of Experiment 2, with three low-income paraprofessional staff members of a neighborhood service center serving as trainees, showed that the percentage of target behaviors increased after the instructional package was introduced for the respective trainee. Audience ratings of public-speaking performance were correlated with direct observations of target responses. All trainees showed marked improvements in audience ratings from pretraining to posttraining. This study demonstrated an effective procedure for training public-speaking behaviors.

Cognitive behavioral therapy for public-speaking anxiety using virtual reality for exposure.

This study used an open clinical trial to test a cognitive-behavioral treatment for public-speaking anxiety that utilized virtual reality as a tool for exposure therapy. Treatment was completed by participants (n = 10) meeting the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria for social phobia, or panic disorder with agoraphobia in which public speaking was the predominantly feared stimulus. Treatment was conducted by a licensed psychologist in an outpatient clinic. Treatment consisted of eight individual therapy sessions, including four sessions of anxiety management training and four sessions of exposure therapy using a virtual audience, according to a standardized treatment manual. Participants completed standardized self-report questionnaires assessing public-speaking anxiety at pre-treatment, post-treatment, and 3-month follow-up. Participants were asked to give a speech to an actual audience at pre- and post-treatment. Results showed decreases on all self-report measures of public-speaking anxiety from pre- to post-treatment, which were maintained at follow-up (n = 8; all P = 05). Participants were no more likely to complete a speech post-treatment than at pre-treatment. This study provides preliminary evidence that a cognitive-behavioral treatment using virtual reality for exposure to public speaking may reduce public-speaking anxiety and suggests that further research with a controlled design is needed.

Public-speaking fears in a community sample. Prevalence, impact on functioning, and diagnostic classification.

BACKGROUND: Recent epidemiologic studies have revealed that social phobia is more prevalent than has been previously believed. An unresolved issue is the extent to which public-speaking fears constitute a recognizable form of social phobia in a community sample and, moreover, to what extent these fears are associated with functional morbidity. METHODS: To examine the prevalence and impact of public-speaking fears and their relationship to social phobia in a community sample, we conducted a randomized telephone survey of 499 residents of Winnipeg, Manitoba, a medium-sized midwestern metropolitan area. RESULTS: One third of the respondents reported that they had excessive anxiety when they spoke to a large audience. The onset of fears was early (ie, 50%, 75%, and 90% by the ages of 13, 17, and 20 years, respectively). Anxious cognitions about public speaking included the following fears: doing or saying something embarrassing (64%), one's mind going blank (74%), being unable to continue talking (63%), saying foolish things or not making sense (59%), and trembling, shaking, or showing other signs of anxiety (80%). In total, 10% (n = 49) of the respondents reported that public-speaking anxiety had resulted in a marked interference with their work (2%), social life (1%), or education (4%), or had caused them marked distress (8%). Twenty-three persons (5%) had public-speaking anxiety in isolation (ie, without evidence of additional kinds of social fears). CONCLUSIONS: These data support the inclusion of severe forms of public-speaking fears within the social phobia construct and, furthermore, suggest that public-speaking anxiety may have a detrimental impact on the lives of many individuals in the community.

Brief virtual reality therapy for public speaking anxiety.

The primary goal of this research program was to investigate the effectiveness of virtual reality therapy (VRT) in reducing public speaking anxiety of university students. The prevalence and impact of public speaking anxiety as a type of Social Phobia are discussed. Studies of VRT as an emerging treatment for psychological problems are reviewed. In the present study, eight students completed VRT individual treatment and post-testing, and six students in a Wait-List control group completed post-testing. Assessment measures included four self-report inventories, self-report of Subjective Units of Discomfort during exposure to VRT and physiological measurements of heart rate during speaking tasks. Four weekly individual exposure treatment sessions of approximately 15 min each were conducted by the author serving as therapist. Results on self-report and physiological measures appear to indicate that four virtual reality treatment sessions were effective in reducing public speaking anxiety in university students, corroborating earlier studies of VRT's effectiveness as a psychotherapeutic modality. Future research directions are discussed, primarily the need for research on younger populations, to assess the effectiveness of VRT for earlier intervention with public speaking anxiety.

Attenuated heart rate responses to public speaking in individuals with alcohol dependence.

BACKGROUND: Because individuals with alcohol dependence (AD) have shown blunted cortisol responses to psychological stress, we assessed whether they also show attenuated cardiovascular responses. This study examined the cardiovascular responses of people meeting DSM-IV criteria for AD to orthostasis and public speaking. METHODS: Heart rate (HR), stroke volume, cardiac output, total peripheral resistance, mean arterial pressure, systolic blood pressure, and diastolic blood pressure during orthostasis and public speaking were assessed by use of impedance cardiography and Dinamap blood pressure monitoring in 20 AD subjects abstinent for 21 to 28 days and in 10 age-matched controls. Orthostasis consisted of standing, whereas public speaking involved preparing and presenting two speeches. Self-reported mood state was also assessed during the tasks. RESULTS: AD subjects had significantly lower resting BP compared with controls. Cardiovascular responses to orthostasis were similar between groups. AD subjects had attenuated HR during public speaking but reported similar anxiety responses to controls. CONCLUSIONS: Comparable cardiovascular responses to orthostasis in controls and AD subjects suggest intact reflex control of circulation. AD subjects had blunted HR responses to public speaking; this is consistent with the attenuated cortisol responses observed in this sample and in previous studies. This suggests a possible alteration in limbic system regulation of hypothalamic and brainstem responses to psychological stress. Cardiovascular responses of AD subjects that are inconsistent with subjective accounts of tension and anxiety suggest a disconnection between perception of threat and resulting physiologic responses in AD subjects.

Virtual Reality Therapy: case study of fear of public speaking.

The major goal of this research case study was to investigate the effectiveness of Virtual Reality Therapy (VRT) in the treatment of the fear of public speaking. A twenty-eight-year-old Caucasian male was selected from questionnaires distributed to a class of undergraduate students enrolled at Kennesaw State University. Two assessment measures were used in this study. The first measure used was the Attitude Towards Public Speaking (ATPS) Questionnaire. The second measure used was the eleven-point Subjective Units of Disturbance (SUD) scale. These measurements assessed the anxiety, avoidance, attitudes and disturbance associated with the subject's fear of public speaking before and after each VRT treatment session. This case study of public speaking fear indicates that VRT may be used as an effective treatment method for reducing self-reported anxiety.

Behavioral assessment of public-speaking anxiety using a modified version of the Social Performance Rating Scale.

The current study aimed to extend the evaluation of the utility of the Social Performance Rating Scale (SPRS) [Behav. Res. Ther. 36 (1998) 995]. We examined the utility of a modified SPRS for the behavioral assessment of public-speaking anxiety among patients with social phobia (n = 49). The videotaped performance of public-speaking fearful patients in a public-speaking task was rated using four of the five SPRS ratings and was compared to global ratings by patients and observers, as well as to self-report and clinician-administered measures of social anxiety. The pattern of correlations with criterion measures of social anxiety provided evidence for the convergent and divergent validity of this modified SPRS for the behavioral assessment of public-speaking anxiety.

Public speaking stress-induced neuroendocrine responses and circulating immune cell redistribution in irritable bowel syndrome.

OBJECTIVES: Augmented neuroendocrine stress responses and altered immune functions may play a role in the manifestation of functional gastrointestinal (GI) disorders. We tested the hypothesis that IBS patients would demonstrate enhanced psychological and endocrine responses, as well as altered stress-induced redistribution of circulating leukocytes and lymphocytes, in response to an acute psychosocial stressor when compared with healthy controls. METHODS: Responses to public speaking stress were analyzed in N = 17 IBS patients without concurrent psychiatric conditions and N = 12 healthy controls. At baseline, immediately following public speaking, and after a recovery period, state anxiety, acute GI symptoms, cardiovascular responses, serum cortisol and plasma adrenocorticotropic hormone (ACTH) were measured, and numbers of circulating leukocytes and lymphocyte subpopulations were analyzed by flow cytometry. RESULTS: Public speaking led to significant cardiovascular activation, a significant increase in ACTH, and a redistribution of circulating leukocytes and lymphocyte subpopulations, including significant increases in natural killer cells and cytotoxic/suppressor T cells. IBS patients demonstrated significantly greater state anxiety both at baseline and following public speaking. However, cardiovascular and endocrine responses, as well as the redistribution of circulating leukocytes and lymphocyte subpopulations after public speaking stress, did not differ for IBS patients compared with controls. CONCLUSIONS: In IBS patients without psychiatric comorbidity, the endocrine response as well as the circulation pattern of leukocyte subpopulations to acute psychosocial stress do not differ from healthy controls in spite of enhanced emotional responses. Future studies should discern the role of psychopathology in psychological and biological stress responses in IBS.

[Public speaking: viewpoint of master's students of nursing].

Communication is a basic element of Nursing; still, speaking in public can be a frightening experience for many nurses. This article intends to study the emotions felt by Master's students in Nursing, identifying how they plan their presentation and what they consider important enough to reveal to the public. Fifty nurses who were enrolled in the Master's program at EEUSP participated in the study. Data was collected through a questionnaire utilizing open-answer questions. Results showed that anxiety was the most frequent emotion related by them. In the planning of a presentation, however confidence in the content of the speaker's text was the most important aspect, while speaking clearly appeared as the most valued characteristic in general.

The white-coat effect is unrelated to the difference between clinic and daytime blood pressure and is associated with greater reactivity to public speaking.

OBJECTIVE: To compare the blood pressure (BP) response to doctor's visit with the BP reaction to a psycho-social challenge and with the difference between clinic and daytime BP (DeltaC-D). SUBJECTS: We studied 64 young stage-1 hypertensive subjects and 33 normotensive controls. MAIN OUTCOME MEASURES: Relationship between direct and surrogate measure of white-coat effect (WCE) and assessment of BP response to public speaking in subjects with normal or increased reaction to BP measurement. METHODS: The responses to BP measurement by a doctor and to public speaking were assessed with beat-to-beat Finapres recording. DeltaC-D was calculated on the basis of two BP monitorings and used as a surrogate measure of WCE. RESULTS: BP and heart rate changes elicited by the visit were unrelated to DeltaC-D and were correlated to the changes caused by the speech test [P <0.001 for systolic BP (SBP), P = 0.01 for diastolic BP (DBP), and P <0.001 for heart rate]. Hypertensive subjects with SBP response to doctor's visit above the median (hyper-reactive) showed increased reactivity also to public speaking (61 +/- 15 mmHg), while those with BP response below the median (normo-reactive) had a response to the psycho-social challenge (40 +/- 21 mmHg, 0.001 versus hyper-reactive) similar to that of the normotensive controls (38 +/- 17 mmHg). Epinephrine urinary output was greater in the hyper-reactive than the normo-reactive subjects (23 versus 12 microg/24 h, = 0.01). The SBP response to public speaking was greater in the hypertensive subjects with higher systolic daytime BP than in those with lower daytime BP (55.3 +/- 20.9 versus 45.1 +/- 20.6 mmHg, = 0.046). CONCLUSIONS: Subjects with increased WCE have an exaggerated response also to psycho-social stimuli. Average daytime BP, which incorporates the BP reactions to many psycho-social triggers can, thus, not be taken as the basal BP of an individual. This helps explain why DeltaC-D does not reflect the true WCE.

Speech disturbances and gaze behavior during public speaking in subtypes of social phobia.

Twenty-four social phobics with public speaking anxiety and 25 nonphobic individuals (controls) gave a speech in front of two people. Subjective anxiety, gaze behavior, and speech disturbances were assessed. Based on subjects' fear ratings of social situations, phobics and controls were divided into the generalized and nongeneralized subtype. Results showed that generalized phobics reported the most, and nongeneralized controls the least anxiety during public speaking. All subjects had longer and more frequent eye contact when delivering a speech than when talking with an experimenter or sitting in front of an audience. Phobics showed more filled pauses, had longer silent pauses, paused more frequently, and spent more time pausing than controls when giving a speech. Generalized phobics spent more time pausing during their speech than the other subgroups (nongeneralized controls, generalized controls, and nongeneralized phobics). These results suggest that generalized phobics tended to shift attentional resources from speech production to other cognitive tasks.
