The role of coach-athlete relationship quality in team sport athletes’ psychophysiological exhaustion: implications for physical and cognitive performance

The present study aimed to examine associations between the quality of the coach-athlete relationship and athlete exhaustion by assessing physiological and cognitive consequences. Male and female athletes (N = 82) representing seven teams across four different sports, participated in a quasi-experimental study measuring physical performance on a 5-meter multiple shuttle test, followed by a Stroop test to assess cognitive performance. Participants provided saliva samples measuring cortisol as a biomarker of acute stress response and completed questionnaires measuring exhaustion, and coach-athlete relationship quality. Structural equation modelling revealed a positive relationship between the quality of the coach-athlete relationship and Stroop performance, and negative relationships between the quality of the coach-athlete relationship and cortisol responses to high-intensity exercise, cognitive testing, and exhaustion. The study supports previous research on socio-cognitive correlates of athlete exhaustion by highlighting associations with the quality of the coach-athlete relationship.     

Leading higher education professionals: local,connected, and artful

In this paper, we explore the work life of a scholar new to academia in her methods of leading informally. We discuss five vignettes that offer moments of learning and reflection, including reducing performance anxiety, privileging financial accountability, the rise of the virtual world, the impact of silence, and the potential for confrontation to strengthen working relationships. We offer suggestions as to how contemporary leaders may adapt to the freedom that artful action offers.     

Perceptions of personal and familial adjustment by children from intact,single-parent,and reconstituted families

The present study investigated children's (N=566) personal and familial adjustment, and sought to determine if this varied as a function of familial configuration and gender. More specifically, these children were surveyed across a broad range of adjustment measures, including self-concept, perception of school adjustment, home adjustment, peer relationships, state and trait anxiety, as well as their evaluations of mother, father, and family. The results from these measures revealed: (a) less positive adjustment among children from divorced families (whether the remaining parent remarried or not) as opposed to children from intact families; (b) mixed findings regarding comparisons of psychosocial adjustment between single-parent and remarried groups; and (c) a pattern of effects related to significant interactions of family type and gender in which males appeared to be favorably affected within the single-parent configuration, while females were more favorably adjusted within the reconstituted family.     

FM: Clinically meaningful rorschach index with minority children?

Recent court actions have spurred psychologists to develop improved assessment tools and to utilize diagnostic measures that take into consideration developmental and affective growth patterns of disadvantaged and minority youth. The present study, working through a case vignette, has weighed the possibility that the FM index may serve as a forerunner of abstract thinking, or the capacity to internalize imagery, which, in Rorschach theory, is, with older subjects, best illustrated in M. Findings also suggest that the Z (Organizational Activity) index may not be useful in evaluating intellectual potentials of preschool minority children. Following blind analysis of the Rorschach, replicative data were obtained through a social history and an individually-administered ability test. Data from these sources support the major finding that FM may enable educational diagnosticians to estimate more accurately the intellectual capabilities of some preschool minority and other culturally disadvantaged children.

Children Develop Initial Orthographic Knowledge During Storybook Reading

We examined whether young children acquire orthographic knowledge during structured adult-led storybook reading even though minimal viewing time is devoted to print. Sixty-two kindergarten children were read 12 storybook “chapters” while their eye movements were tracked. Results indicated that the children quickly acquired initial mental graphemic representations of target nonwords. This learning occurred even though they focused on the target nonwords approximately one fourth of the total time while viewing the pages. Their ability to acquire the initial orthographic representations of the target nonwords and their viewing time was affected by the linguistic statistical regularities of the words. The results provide evidence of orthographic learning during structured storybook reading and for the use of implicit linguistic statistical regularities for learning new orthographic word forms in the early stages of reading development.     

Neophobias and conditioned taste aversions in rats following exposure to novel flavors

Rats were successively exposed to three solutions with distinctively different flavors and then tested for both neophobia and propensity to form conditioned taste aversions to a fourth distinctively flavored solution. All permutations between the four solutions (salty, bitter, sweet, and sour) were examined. The prior exposures resulted in attenuation of neophobia to novel salty and sour solutions, but not to equally novel bitter or sweet solutions. These effects were found to depend upon thediversity of the prior ingestive events rather than upon either a single specific flavor experience or a summation of the reductions in generalized neophobia accrued by each substance separately; both of the latter findings are inconsistent with stimulus generalization being responsible for the observed attenuation of neophobia to salty and sour solutions following exposure to diverse different solutions. A further test of generalization between the salty and bitter solutions, consisting of associating one flavor with poison and extinguishing the avoidance response in half the animals prior to testing for generalization of conditioned taste aversion to the other flavor, also proved negative. Although these effects of exposure to flavors distinctly different from the test solution may be dependent upon solution concentrations, further research found that the same pretest exposures and same test concentrations failed to inhibit formation of conditioned taste aversions. A demonstration of “latent inhibition” attested to the sensitivity of our procedure to potential interference with acquisition of conditioned taste aversions. The results are considered in light of the relationship between neophobia and conditioned tasted aversions, the differential biological relevancy of specific tastes, and abstraction as a cognitive capability of rats. The possibility is raised that the defense against toxins is not the primary function of neophobia.     

Strengths and Weaknesses of Non-enhanced and Contrast-enhanced Cadaver Computed Tomography Scans in the Teaching of Gross Anatomy in an Integrated Curriculum

Cadaver-specific postmortem computed tomography (PMCT) has become an integral part in anatomy teaching at several universities. Recently, the feasibility of contrast-enhanced (CE)-PMCT has been demonstrated. The purpose of this study was to identify particular strengths and weaknesses of both non-enhanced and contrast-enhanced PMCT compared to conventional cadaver dissection. First, the students’ perception of the learning effectiveness of the three different modalities have been assessed using a 34-item survey (five-point Likert scale) covering all anatomy course modules. Results were compared using the nonparametric Friedman Test. Second, the most frequent artifacts in cadaver CT scans, were systematically analyzed in 122 PMCT and 31 CE-PMCT data sets to quantify method-related limitations and characteristics. Perfusion quality was assessed in 57 vascular segments (38 arterial and 19 venous). The survey was answered by n = 257/320 (80.3%) students. Increased learning benefits of PMCT/ CE-PMCT compared to cadaver dissection were found in osteology (2/3 categories, P < 0.001), head and neck (2/5 categories, P < 0.01), and brain anatomy (3/3 categories, P < 0.01). Contrast-enhanced-PMCT was perceived particularly useful in learning vascular anatomy (10/10 categories, P < 0.01). Cadaver dissection received significantly higher scores compared to PMCT and CE-PMCT in all categories of the abdomen and thorax (7/7 categories, P < 0.001), as well as the majority of muscular anatomy (5/6 categories, P < 0.001). Frequent postmortem artifacts (total n = 28, native-phase n = 21, contrast injection-related n = 7) were identified and assessed. The results of this work contribute to the understanding of the value of integrating cadaver-specific PMCT in anatomy teaching.     

College courses and changes in dogmatism

To observe the impact of an experimental human relations course and to compare changes occurring in students in this course with changes in students having other University experiences, most University of Minnesota entering freshmen were asked to complete the Rokeach Dogmatism Scale before the beginning of the school year in 1970, and selected groups were retested at the end of the first quarter. Mean dogmatism scores for all groups, including the experimental group, declined. In terms of dogmatism, the results did not suggest that the experimental course had a unique effect on students. Students selecting varying college experiences differed extensively at both times of testing and retesting.The author expresses his appreciation to James Rounds, who assumed much responsibility for the collection and analysis of the data.
