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.

Créativité verbale et valence émotionnelle : « Je deviens plus créatif quand je vois un mot positif ! »

IntroductionThe modulating effect of emotion on creativity is one of the most current topics in cognitive research. Emotion, and particularly positive emotion, is supposed to be conducive of creativity and to enhance the processes of creative thinking.ObjectiveThis work aimed to study the modulating effect of emotional valence of the task material (words-stimuli) as well as the emotional valence of the task instructions on verbal creativity performance.MethodAn experiment was conducted on a set of 27 stimuli-words and six instructions-phrases selected on the basis of pretest valence ratings. The valence of the stimuli-words (negative, neutral and positive) was crossed with the valence of the instructions-phrases (negative, neutral and positive) in a 3 × 3 factorial design. However, only five experimental conditions were considered relevant and used in the Experiment. Three components of verbal creativity identified in the literature were measured: fluidity, flexibility and originality.ResultsResults showed that positive instructions and words increased verbal creativity, especially the originality of the responses, which is considered as a basic component of creativity. Conversely, negative valence had an inhibitory and obstructive effect on verbal creativity.ConclusionThis study supports previous research showing the existence of a significant influence of emotional valence of words on cognitive functioning, and adds to the very little (or absent) research on the modulating effect of the valence of instructions and on the relationship between verbal creativity and emotional valence, a relationship that can be fostered in education.     

Flexibility over automaticity: Separable representations for colours and words

This study demonstrates that associations between colour words and the colours they denote are not mandatory. Experiments 1–3 used a go/no-go task in which participants responded to one print colour and one word and withheld response from another print colour and another word. In Experiment 1, the content of the words denoted noncolour entities. In Experiment 2 the two words denoted two colours that were different from the target print colours. In Experiment 3, the words denoted the same colours as the target print colours but each response set included incompatible print colour and word (e.g., one response to the print colour blue and the word “green” and another response to the print colour green and the word “blue”). Participants performed equally well in all the experiments. Experiment 4a used Arabic digits and words denoting numbers, two formats that are known to have shared representations. Here, participants had difficulties separating their responses to the digits and words. These results suggest that representations of words are distinct from the content that they represent, supporting the existence of distinct verbal and colour modules.     

Can membership-functions capture the directionality of verbal probabilities?

Verbal probabilities are a common mean for communicating risk and uncertainties in many decision-making settings (e.g., finance, medicine, military). They are considered directional because they elicit a focus on either the outcome occurrence (e.g., there is a chance) or on its non-occurrence (e.g., it is unlikely). According to a quantitative perspective, directionality is dependent on the vague probabilistic meaning conveyed by verbal probabilities—e.g., p(outcome) > .50 = > focus on outcome occurrence. In contrast a more qualitative perspective suggests that directionality depends on contextual factors. The present study tested whether the directionality of verbal probabilities was determined by their vague probabilistic meaning, by contextually manipulated variables (i.e., representativeness and base rate), or by a combination of both. Participants provided their own expressions to describe the guilt of a suspect and then assessed the vague probabilistic meaning and directionality associated with those expressions. Results showed that directionality was mainly determined by the vague probabilistic meaning but also by the base rate of guilt. Although attention focus on the occurrence or the non-occurrence of the target outcome is dependent on vague probabilistic meaning, it cannot be fully accounted for by it.     

Effects of membership change on open discussion and team performance: The moderating role of team tenure

This study identified temporal conditions when membership change may enhance or diminish team functioning. Using a longitudinal repeated measures design surveying 41 R&D teams, this study examined whether team tenure moderated the relationship of membership change with open discussion and team performance. The results illustrated that increasing membership change was positively associated with both open discussion and team performance for newly formed teams, whereas this association was negative for long-serving teams. Thus, what matters is not so much whether a team's membership changes but rather whether the team's longevity supports or impedes adaptation to personnel changes.     

Effects on organizational context (culture and climate) from implementing a 360-degree feedback system: The case of Arcelik

The current study aims to investigate the impact of the 360-degree feedback system (DFS) on organizational context (culture and climate). This longitudinally designed study was conducted at the Arcelik Cooking Appliances Plant in Turkey with 77 white-collar workers. 360-DFS was based on relevant literature and feedback given to the employees by The Arcelik Competency Model. Results have shown that the 360-DFS has effects on organizational context (e.g., employees' perceptions regarding support and achievement culture). The results have also revealed some significant effects on the participants' perception of the communication and performance appraisal system in the organization.     

Issues in using interpreters in therapeutic work with refugees. What is not being expressed?

‘Interpreting’ could be thought about as a legal equal opportunities or human rights issue. Whereas interpreters are likely to focus on the linguistic issues, and will be aware of the technical complexities of their work. Clinicians may worry about the impact on the therapeutic relationship of the interpreter's presence, how this will be managed and how it may depend on the match or mismatch of such factors as the client's gender, age and first or other language. This paper considers the issue on each of these levels to reveal the complexities and dilemmas of effective clinical work with interpreters, but also what can be achieved: the multiple layers of meaning concerning the client's experience and communication which can be elicited through effective working between interpreter and clinician.     

How can a stereotype inconsistency bias be encouraged in communication?

This study aimed to investigate what conditions can lead to a bias for communicating stereotype inconsistent (SI) information, relative to stereotype consistent (SC) information. Sixty‐three undergraduate university students (22 males, 41 females; M_age = 21.25) read a story about an Arab man who exhibited characteristics consistent and inconsistent with the stereotype of Arab men. The story was transmitted through 21 three‐person communication chains; each participant rewrote the story from memory for the next person in the chain to read, with only the first participant in each chain reading the original story. As hypothesized, when a surprising category conjunction was formed by pairing the primary stereotype (Arab men) with a secondary stereotype of a contradictory nature (kindergarten teachers), SC information was circulated less than SI information. This was also the case when a causal explanation was provided that accounted for the unexpected SI information. Findings indicate the potential of techniques that elicit cognitive elaboration of SI information to encourage an SI bias in communication, and show promise for exploring ways to reduce the impact of negative stereotypical information in the long term.     

Attributions for Memory Performance in Adulthood: Age Differences and Mediation Effects

We examined age differences in attributions to internal (controllable and uncontrollable), external (uncontrollable), and unstable factors for performance on a free recall memory task in 149 young, middle-aged, and older adults. Attributions varied by age and by level of memory performance. Middle-aged and older adults rated internal, uncontrollable factors (ability and genes) as more influential for high performance than for low performance, and they were less likely than young adults to attribute low performance to these factors. Within age groups, only the older adults rated memory ability as more influential than strategy use, even though they were as likely as the other age groups to use a categorization strategy. Attributions to both internal controllable (strategy use) and uncontrollable (ability) factors as well as to health were associated with better memory performance. These attributions partially mediated the relationship between age and memory performance. Thus, attributions may provide some insight into sources of age differences in memory performance.
