The relationship between tertiary-level students’ self-perceived presentation delivery and public speaking anxiety: A mixed-methods study

Abstract

Oral presentations are common in higher education worldwide. There is no shortage of evidence substantiating the association between oral presentations and anxiety. In the light of the close connection between self-perception and anxiety, and the under-researched nature of the delivery aspect of presentations (e.g. use of voice and body language), this study explored the relationship between tertiary-level learners’ (n?=?211) perceived delivery competence (23 areas) and their levels of public speaking anxiety. The data were collected via questionnaires and interviews. The questionnaire results revealed highly significant correlations between anxiety and 22 of these areas. The 23 areas overall also had a highly significant predictive power for anxiety levels, indicated by their explaining 45% of the variance. Follow-up in-depth semi-structured interviews were conducted with six participants to shed light on these quantitative findings. This article ends with an argument for greater emphasis on presentation delivery skills in higher education, which can potentially mitigate learners’ public speaking anxiety.     

Comorbidity of PTSD in anxiety and depressive disorders: Prevalence and shared risk factors

The present study aims to assess comorbidity of posttraumatic stress disorder (PTSD) in anxiety and depressive disorders and to determine whether childhood trauma types and other putative independent risk factors for comorbid PTSD are unique to PTSD or shared with anxiety and depressive disorders. The sample of 2402 adults aged 18–65 included healthy controls, persons with a prior history of affective disorders, and persons with a current affective disorder. These individuals were assessed at baseline (T0) and 2 (T2) and 4 years (T4) later. At each wave, DSM-IV-TR based anxiety and depressive disorder, neuroticism, extraversion, and symptom severity were assessed. Childhood trauma was measured at T0 with an interview and at T4 with a questionnaire, and PTSD was measured with a standardized interview at T4. Prevalence of 5-year recency PTSD among anxiety and depressive disorders was 9.2%, and comorbidity, in particular with major depression, was high (84.4%). Comorbidity was associated with female gender, all types of childhood trauma, neuroticism, (low) extraversion, and symptom severity. Multivariable significant risk factors (i.e., female gender and child sexual and physical abuse) were shared among anxiety and depressive disorders. Our results support a shared vulnerability model for comorbidity of anxiety and depressive disorders with PTSD. Routine assessment of PTSD in patients with anxiety and depressive disorders seems warranted.     

University reputation and undergraduates’ self-perceived employability: mediating influence of experiential learning activities

ABSTRACT

Stratification, in the form of silent exclusion that is experienced by some groups of students because of the perceived low reputation of the university attended, and which the students have no control over, has been observed as a social menace that works against the concept of equity in education. To address this problem, a need exists for universities with lower reputations to go the extra mile to develop the employability skills of their students, which, in turn, will enhance their self-perception of employability. The major objective of this study was to investigate the influence of experiential learning activities on the relationship between university reputation and self-perceived employability among undergraduates in South African universities. Data were collected by means of an adapted questionnaire from 402 respondents drawn from two universities in the same province in South Africa. To achieve our objective, four hypotheses were formulated and tested through Structural Equation Modelling (SEM) using AMOS 25. The findings show that both direct and indirect effects of university reputation on undergraduates’ perceived employability through experiential learning activities are positively significant. To minimise the negative effects that universities with low reputations are likely to have on undergraduates’ acquisition of experiential learning, on their self-perceived employability, and subsequently on their employment prospects, the government, the Department of Higher Education and universities (particularly, the low-rated ones in South Africa) need to put in place some timely interventions, some of which are suggested in the study.     

Correlates of kindergarten adjustment: Temperament and communicative competence

The kindergarten adjustment of 217 Causasian children (mean AGE=70 months) was examined in relation to their temperament and communicative competence. Both communicative competence and various dimensions of temperament accounted for a significant proportion of the variance in kindergarten adjustment. Children who were evaluated as normal-to-advanced in their level of competence were found to be significantly more adjusted to kindergarten than were those assessed as delayed. Along with age and gender, the temperament dimensions of attention span-distractibility, rhythmicity, general activity level, and mood were significantly predictive of children's adjustment. An understanding of these factors can help parents and professionals promote a successful initial experience within the educational system.     

Implementing Organizational Change: Correlates of Success and Failure

According to many professional publications, organizational change represents a major challenge for managers today. The purpose of this study was to determine the major reasons why organizational changes fail and the major reasons why changes succeed. The research instrument was a questionnaire. Respondents were asked to describe one specific change effort that has occurred in the last two years. The respondents were 210 managers from a cross‐section of industries and job‐functions across North America. Findings were summarized in the form of eleven conclusions that dealt with types of organizational changes, complexity of change efforts, success rates, sponsorship, internal and external factors that motivate change, measures of success, correlates of success, and, separately, correlates of failure, respondents' recognition of key “enablers” and “barriers” to change, and the extent to which enablers and barriers are common across different types of change. The article ends with a list of nine recommendations for the management of organizational change.     

Correlates of formal reasoning: Content and problem effects

Piaget's structural theory of formal thought suggests that a general construct of formal reasoning exists. The content of the task and type of problem employed are often ignored in Piagetian based studies but are important for generalizing findings to other studies and to educational problems. The study reported here examines content and problem effects of formal thought in 13-year-old adolescents. Specifically, three controlling variables tasks with different content and two question type tests (analysis and controlling questions) were administered to 120 seventh graders. Ability measures and personality dimensions associated with formal reasoning in the literature are used to clarify what formal reasoning is and how content and problem type are involved in formal reasoning. Significant main effects were found for problem and content effects (p = 0.001), and a significant interaction was found between the two (p = 0.001). Across the three tasks general ability, field dependency, and locus of control were consistently and significantly related to the controlling questions. However, only measures of field dependency were related to the analysis questions. Combinations of ability and personality factors were found to be uniquely related to each task, within each question type. Results have implications for a theory of formal thought and the teaching of the controlling variables strategy.     

Behavioral and relational correlates of low self-perceived competence in young children

It is developmentally normative for preschoolers (aged four to five years) to have self-perceptions that are typically positive and even over-inflated. However, because not all children have positive self-perceptions in early childhood it is important to understand factors that influence the development of self-perceptions, especially low self-perceptions, in early childhood. Therefore, this study examined the associations between self-perceptions and teacher ratings of social behaviors, subtypes of withdrawal, and peer ratings of acceptance/rejection in preschoolers. Participants included 199 children (107 males, 92 females) attending two early childhood programs in a midsized community in the western United States. The major findings were that children in early childhood who have lower self-perceptions of their abilities than their peers tended to engage in more reticence, solitary-passive withdrawal, and solitary-active behavior.     

Correlates of peer victimization and achievement: An exploratory model

This study investigates peer victimization and achievement. Adolescents aged 12–15 years were drawn from the National Longitudinal Survey of Children and Youth, which is a stratified random sample of 22,831 households in Canada. Teachers', children's, and parents' reports were combined in a latent variable path analysis, χ²(51) = 348.54, p < .000. The model converged in six iterations resulting in a Comparative Fit Index = .90, and a standardized residual mean error of .05. The model shows that adolescents who are victimized by their peers are at risk of experiencing poor school achievement if they exhibit disruptive behaviors, receive little support from their teachers, and experience non‐nurturing, rejecting behaviors from their parents. © 2009 Wiley Periodicals, Inc.     

The instructor self-evaluation form: Development and validation of an ipsative forced-choice measure of self-perceived faculty performance

An ipsative forced-choice college faculty self-evaluation questionnaire was developed. The instrument was validated by comparing self-evaluation scores to student rating scores and by comparing superior and nonsuperior instructors on the basis of student ratings. Both analyses yielded positive, but modest, indications of validity. Implications are discussed relative to the questionnaire's utility in faculty development activities.     

Development and validation of ageist myths in a psychotherapy questionnaire (AMPQ): professional ageism among psychology graduate students

ABSTRACT

Ageism is a problem in aging societies. Clinical psychologists and undergraduate psychology students have shown negative attitudes toward older adults. However, no speci?c measure against ageist myths in the psychotherapeutic context is available. This study aims to develop and present the psychometric properties of the Ageist Myths about Psychotherapy Questionnaire (AMPQ).

These issues were examined by surveying 222 psychology graduates at higher education institutions about their attitudes and behaviors concerning psychotherapy with older adults, negative stereotypes toward aging, and attitudes toward dementia.

Using principal components analysis, 10 items were retained and one factor was obtained with an acceptable reliability index. Signi?cant associations were found between the AMPQ and negative stereotypes toward aging, and attitudes toward dementia.

Results revealed that universities and colleges with psychology programs have an ageist bias. Implications for college formation in aging, and older adults with mental health problems, are discussed and presented.     

Neural Correlates of Belief- and Desire-Reasoning

Theory of mind requires an understanding of both desires and beliefs. Moreover, children understand desires before beliefs. Little is known about the mechanisms underlying this developmental lag. Additionally, previous neuroimaging and neurophysiological studies have neglected the direct comparison of these developmentally critical mental-state concepts. Event-related brain potentials were recorded as participants ( N  =   24; mean age   =   22 years) reasoned about diverse-desires, diverse-beliefs, and parallel physical situations. A mid-frontal late slow wave (LSW) was associated with desire and belief judgments. A right-posterior LSW was only associated with belief judgments. These findings demonstrate neural overlap and critical differences in reasoning explicitly about desires and beliefs, and they suggest children recruit additional neural processes for belief judgments beyond a common, more general, mentalizing neural system.     

Correlates of Reading Fluency in Arabic: Diglossic and Orthographic Factors

Arabic native speaking children are born into a unique linguistic context called diglossia (Ferguson, word, 14, 47–56, [1959]). In this context, children grow up speaking a Spoken Arabic Vernacular (SAV), which is an exclusively spoken language, but later learn to read another linguistically related form, Modern Standard Arabic (MSA). Forty-two first-grade Arabic native speaking children were given five measures of basic reading processes: two cognitive (rapid automatized naming and short-term working memory), two phonological (phoneme discrimination and phoneme isolation), and one orthographic (letter recoding speed). In addition, the study produced independent measures of phonological processing for MSA phonemes (phonemes that are not within the spoken vernacular of children) and SAV phonemes (phonemes that are familiar to children from their oral vernacular). The relevance of these skills to MSA pseudoword reading fluency (words correct per minute) in vowelized Arabic was tested. The results showed that all predictor measures, except phoneme discrimination, correlated with pseudoword reading fluency. Although phonological processing (phoneme isolation and discrimination) for MSA phonemes was more challenging than that for SAV phonemes, phonological skills were not found to affect reading fluency directly. Stepwise regression analysis showed that the strongest predictor of reading fluency in vowelized Arabic was letter recoding speed. Letter recoding speed was predicted by memory, rapid naming, and phoneme isolation. The results are discussed in light of Arabic diglossia and the shallow orthography of vowelized Arabic.     

Correlates of faculty publication productivity: A cross-national analysis

This study is a cross-national empirical analysis ofthe correlates of faculty publication productivity ina ten-country sample. The countries included in thestudy are as follows: Australia, Brazil, Chile, HongKong, Israel, Japan, Korea, Mexico, the UnitedKingdom, and the United States. Publicationproductivity was measured as number of articlespublished over a three-year period. By reviewing thefindings of related literature on the professoriate inthe developed world, the study seeks to determine theextent to which these hold for less developed academicsystems as well, and more broadly, to identifysimilarities and differences in the patterns ofpublication productivity across the examined nations.The statistical analyses conducted for each countryreveal differences that clearly challenge theunqualified application of established researchproductivity models to other national contexts.     

Correlates of formal operational reasoning: A neo-piagetian analysis

Most Piagetian formal operational reasoning tasks show horizontal decalage; that is, subjects pass certain tasks and fail others that have the same logical structure. The study reported here analyzes the importance of individual difference variables, as postulated by the neo-Piagetian theory of Pascual-Leone, in explaining subject performance in formal reasoning. A sample of 72 freshman students were administered a test of formal reasoning having 20 items of different types of reasoning, and the tests of the individual difference variables. Results obtained from multiple regression analyses show that Pascual-Leone's structural M-capacity (M_s) is the most consistent predictor of success in the different formal reasoning tasks, followed by Witkin's cognitive style, and to a much lesser degree Raven's progressive matrices, and Pascual-Leone's functional M-capacity (M_f). It was found that in the total score on the 20 items of formal reasoning, M_s accounted for 23.3% of the variance (R = 0.483, F = 6.39, p = 0.014) and Witkin's Group Embedded Figures Test, increased the multiple R significantly (F = 7.77, p = 0.007) and accounted for 7.6% of the variance. M_f and the Raven test did not make a significant contribution to the regression equation. Correlation coefficients among most of the items having the same reasoning pattern but different content are generally low but statistically significant (p < 0.01). Intercorrelations among items having the same formal reasoning pattern and content are fairly high (p < 0.001). These results emphasize the importance of individual difference variables: information-processing capacity (Pascual-Leone) and oversensitivity to potentially misleading information (Witkin). It is suggested that in order to understand student performance in formal reasoning tasks, we should expect horizontal decalages as a rule and not the exception, as Piaget had postulated. Educational implications are drawn.     

Teaching STEM after school: Correlates of instructional comfort

Science, technology, engineering and mathematics (STEM) education is a critical component of federal policymakers' agendas. Out-of-school time (OST) programs are designated as an important venue to teach STEM to K–12 students. Using a sample of OST direct staff in Pennsylvania (n = 133), the present analysis examines instructional methods used for STEM lessons and then explores the comfort level that staff have teaching STEM. About 20% or more of staff are not comfortable teaching STEM, depending on the subject. Multivariate analyses (Mann-Whitney tests) also show that staff with fewer STEM credentials, and who work in less-networked programs, or programs with less STEM instruction overall, are more likely to express discomfort teaching STEM. Policy and planning implications are discussed.     

Emeritus professors: Correlates of professional activity in retirement

The major purpose of this study was to investigate correlates of professional activity of professors in retirement. The investigation focused on a number of variables related to the nature of academic work, including professional role orientation, professional affiliations and contacts, material supports, department, and the state of knowledge in various fields. Sixty-four University of Iowa emeritus professors who continued to reside in the Iowa City area during the entire year, and thus had opportunity to maintain University contacts and use University facilities, were interviewed. The most striking finding was the high degree of consistency between level of professional activity during the preretirement career and level of professional activity in retirement. Significant correlates of professional activity in retirement included rated importance of research or other creative work, strength of ties to colleagues and professional organizations outside the University, contacts with former students, and departmental membership in the older, traditional professions.This article is based in part on the author's Ph.D. dissertation submitted to the Department of Higher Education at The University of Iowa and was partially supported by a 1978 Research Award in gerontology from the Multidisciplinary Gerontology Center of The University of Iowa, Iowa State University, and The University of Northern Iowa. The author wishes to acknowledge the valuable suggestions made by Professors H. Bradley Sagen, Department of Higher Education, and Hallowell Pope, Department of Sociology, throughout the study.     

Communication Correlates of Perceived Machiavellianism of Supervisors: Communication Orientations and Outcomes

This paper reports the development of the Perceived Supervisor Machiavellian Measure (PSMM) for use in the organizational communication context. Data were drawn from full-time employees who were part-time graduate students in a corporate and organizational communication program. Employees' perceptions of supervisor Machiavellianism were negatively related to employees' perceptions of supervisor credibility (competence, caring, and trustworthiness), employees' attitudes toward the supervisor, employee motivation, and employee job satisfaction. Supervisors' perceived communication behaviors (nonverbal immediacy, responsiveness, and assertiveness) accounted for a significant amount of variance in perceived supervisor Machiavellianism. The results support a general model of supervisor behavior and provide a foundation for future research in organizational communication.
