The Distinct Roles of First Impressions and Physiological Compliance in Establishing Effective Teamwork

Objective measures of team dynamics would be valuable complementary tools for researchers and practitioners to use along with subjective measures when deciding which individuals work together most effectively as a team, or when designing training or task environments to promote more effective teams and teamwork. Consistent with control theory, the present study investigates how first impressions and physiological compliance early during team formation impact team effectiveness outcomes including: team satisfaction, work-related flow experiences, team processes, and performance outcomes. In a theory-driven attempt to objectively measure the extent of mutual control during teamwork, physiological compliance was calculated as root-mean squared (RMS) error of instantaneous ventilatory drive between participants; lower RMS error indicated higher physiological compliance. Ad hoc two-person teams (N=55) participated in a simulated business and marketing decision-making task while their breathing was monitored continuously. Results from Actor-Partner Interdependence Model (APIM) and mixed-model analyses indicated that first impressions and physiological compliance early during team formation both influenced team effectiveness outcomes: first impressions were predictive of team satisfaction, shared work-related flow experiences and interpersonal processes, while physiological compliance was predictive of performance satisfaction and objective task performance. Overall, results provided initial validation of an objective measure of physiological compliance and show how team dynamics early in team formation can impact overall team effectiveness. Observed relationships suggest that subjective indicators of team formation may only provide a partial view of team dynamics while the addition of an objective indicator of mutual control affords a more comprehensive and in-depth examination

Media Presence and Inner Presence: The Sense of Presence in Virtual Reality Technologies

Abstract. Presence is widely accepted as the key concept to be considered in any research involving human interaction with Virtual Reality (VR). Since its original description, the concept of presence has developed over the past decade to be considered by many researchers as the essence of any experience in a virtual environment. The VR generating systems comprise two main parts: a technological component and a psychological experience. The different relevance given to them produced two different but coexisting visions of presence: the rationalist and the psychological/ecological points of view. The rationalist point of view considers a VR system as a collection of specific machines with the necessity of the inclusion \ud of the concept of presence. The researchers agreeing with this approach describe the sense of presence as a function of the experience of a given medium (Media Presence). The main result of this approach is the definition of presence as the perceptual illusion of non-mediation produced by means of the disappearance of the medium from the conscious attention of the subject. At the other extreme, there \ud is the psychological or ecological perspective (Inner Presence). Specifically, this perspective considers presence as a neuropsychological phenomenon, evolved from the interplay of our biological and cultural inheritance, whose goal is the control of the human activity. \ud Given its key role and the rate at which new approaches to understanding and examining presence are appearing, this chapter draws together current research on presence to provide an up to date overview of the most widely accepted approaches to its understanding and measurement

Role of Inspiration in Increasing Situational Motivation in Male Team Athletes

Motivation and inspiration are often used superficially and synonymously in media coverage of sport. Sportscasters and reporters speculate about athlete motivation cite inspirational locker room speeches from coaches as a motivational source. Research in and out of sport psychology has developed and verified theories to describe mechanisms of motivation change (Deci & Ryan, 1985; Vallerand, 1997), but there is little research on the role of inspiration (Thrash & Elliot; 2003, 2004). The current study aimed to determine if inspiration can be manipulated, and if so, how increased inspiration impacts situational motivation of athletes. A two-way repeated measures ANOVA revealed that inspiration increased for collegiate football players randomly assigned to observe a simulated pep-talk but not for their counterparts assigned to a control group. Situational autonomous motivation did not exhibit a similar response. Multiple regression analysis revealed that change in inspiration was not predictive of change in situational motivation. The results support the contention that inspiration and situational motivation are distinct constructs. Future research in sport should attend to examining consequences of inspiration change in athletes to clarify the role of inspiration contrasted against motivation in sport

Cognitive-Behavioral Treatment of Social Anxiety Disorder and Comorbid Paranoid Schizophrenia

We report on the cognitive-behavioral treatment (CBT) of a patient with comorbid social anxiety disorder (SAD), schizophrenia, and major depressive disorder, complicated by alcohol abuse. Symptoms included auditory hallucinations that commented on the patient’s behavior and paranoid thoughts. The paranoid symptoms affected his social interactions as this included the fear that his thoughts may be heard and judged by others. Therapeutic activities raised awareness as to how avoidance interferes with and perpetuates the cycle of depression and psychosis while maintaining symptoms of SAD. Psychoeducation was provided about factors that maintain social anxiety and increase social isolation. New skills were obtained by helping the patient discover alternative ways to view social situations, experimentation, and real-world application to disprove notions about others’ predicted behavior. Treatment led to a great reduction in social anxiety, depression, and suspicious thinking. This case study demonstrates that SAD symptoms in a patient experiencing psychosis can be effectively treated using CBT

Self-Reported Acceptance of Social Anxiety Sypmtoms: Development and Validation of the Social Anxiety-Acceptance and Action Questionnaire

Mindfulness-based interventions have been used in the treatment of social anxiety with initial success. Mindfulness is defined as an awareness and acceptance of the present moment. Acceptance when used as a coping strategy is related to reduced distress during anxiety-provoking tasks and increased willingness to experience unpleasant events. The purpose of this research was to examine acceptance, willingness and distress in the context of social anxiety and was threefold. The first study was designed to develop an instrument designed to assess acceptance specific to social anxiety. In Study 1, a sample of 352 undergraduates completed the initial 56-item pool of the Social Anxiety-Acceptance and Action Questionnaire (SA-AAQ) with the goal of item reduction. The second study was designed to validate this measure and clarify the factor structure of the SA-AAQ. Participants (n = 339) completed the SA-AAQ in addition to measures of mindfulness and social anxiety. Results indicated that the SA-AAQ is a reliable and valid measure of acceptance specific to social anxiety. The third study was an experimental manipulation that was designed to examine the relationships among acceptance of social anxiety symptoms, willingness and distress. It was hypothesized that individuals who are habitually higher in acceptance would experience reduced anxiety and increased willingness in response to a speech task than those who are low in acceptance. In addition, it was believed that inducing state acceptance using brief instructions would result in decreased distress and increased willingness as compared to suppression and control groups. The results demonstrated that trait acceptance of social anxiety symptoms was associated with lower levels of distress following the speech. It was also found that inducing state acceptance led to similar levels of distress as inducing suppression. Further research is warranted to further clarify this finding. In sum, these three studies combine to provide support that this instrument is a valid measure of the construct that it was designed to assess, namely acceptance specific to social anxiety. The SA-AAQ could be of benefit for assessing mechanisms of change within mindfulness-based treatment protocols for social anxiety, in addition to contributing to the mindfulness literature

The critical effect : evaluating the effects and use of video game reviews

Game reviews play an important role in both the culture and business of games – the words of a reviewer can have an influential effect on the commercial success of a video game. While reviews are currently used by game developers to aid in important decisions such as project financing and employee bonuses, the effect of game reviews on players is not known. Additionally, the use of game reviews to improve evaluation techniques has received little attention. In this thesis we investigate the effect of game reviews on player experience and perceptions of quality. We show that negative reviews cause a significant effect on how players perceive their in-game experience, and that this effect is a post-play cognitive rationalization of the play experience with the previously-read review text. To address this effect we designed and deployed a new heuristic evaluation technique that specifically uses game reviews to create a fine-grained prioritized list of usability problems based on the frequency, impact, and persistence of each problem. By using our technique we are able to address the most common usability problems identified by game reviews, thus reducing the overall level of negativity found within the review text. Our approach helps to control and eliminate the snowballing effect that can be produced by players reading reviews and subsequently posting their own reviews, and thus improve the commercial success of a game

The effects of projected films on singers' expressivity in choral performance

Title from PDF of title page, viewed on July 23, 2013Dissertation advisor: Charles RobinsonVitaIncludes bibliographic references (pages 224-259)Thesis (Ph.D.)--Conservatory of Music and Dance and School of Education. University of Missouri--Kansas City, 2013The purpose of this study was to investigate the effects of projected film visuals on singers' expressivity in choral performance. The study was divided into three phases. In Phase One, university choir singers (N = 21) viewed eight audiovisual pairings (two film excerpts and four choral etudes) and rated these pairings according to perceived music to film congruency. Based on these ratings, two choral etudes were identified that elicited the broadest congruency contrasts when paired with the film segments. In Phase Two, a different group of university choir singers (N = 116) rehearsed and prepared both of the selected choral etudes referred to as “Doh” and “Noo.” Subsequently, these singers were organized into smaller chamber ensembles (n = 11), and performed each choral etude three times under the following conditions: (1) while viewing congruent film, (2) while viewing incongruent film, and (3) with no film projected. After each performance, singers reported their level of self-expression. At the completion of all three performances, singers reported their preferred performance condition. Finally, participants listened to their audio-recorded performances and rated these for performance expressivity and personal preference. During Phase Three, choral experts (N = 8) rated performance expressivity and reported personal preference for each audio-recorded performance. A two-way ANOVA with repeated measures found significant main effects of both etude and film visual performance condition on participants' expressivity ratings (p < .001). Additionally, a significant etude x film visual performance condition interaction was discovered (p = .001). Participants rated self-expression significantly higher when singing with a congruent film compared with other conditions for both etudes (p < .001). Chi-square tests found most preferred experiences during congruent performances, and least preferred experiences during incongruent performances for both etudes (p < .001). Expressivity ratings for audio-recorded performances indicated significantly higher expressivity ratings for the performances influenced by the congruent film visual of etude “Doh” (p < .05), while no significant differences were found for etude “Noo” (p > .05). Implications of these findings are discussed in relation to filmmaking techniques, music education curriculum, choral rehearsal pedagogy, and composition/performance practice, with recommendations for future research.Introduction -- Review of literature -- Methodology -- Results -- Discussion -- Appendix A.

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills
