How could process-oriented research approaches capture the interplay between training and competition in athlete performance preparation? The contribution of ecological dynamics

Analyses of training or competition environments traditionally tend to adopt a product-oriented perspective through the recording and statistical analysis of performance outcomes. Consequently, most investigations continue to ignore the processes underpinning functional achievement of outcomes, therefore, failing to examine contextual effects of how and why performance evolves. This critical research note highlights the need for sport psychologists, pedagogues, and other applied scientists to consider a range of alternative methodological designs for research to monitor and explain processes inherent to performance preparation. These process-oriented designs require the continuous flow and exchange of performance data between training and competition, mediated by practitioners’ experiential knowledge. We endorse a triangulation of information defined as a ‘competition-coach-training’ triad which needs to be better acknowledged. Redirecting the focus of practice and research away from a product-oriented (driven by broad statistical data patterns), towards a process-oriented perspective (examined through in-depth contextual analyses) may re-calibrate the theory-practice alignment.     

Dynamics of phonological cognition

A fundamental problem in spoken language is the duality between the continuous aspects of phonetic performance and the discrete aspects of phonological competence. We study 2 instances of this problem from the phenomenon of voicing neutralization and vowel harmony. In each case, we present a model where the experimentally observed continuous distinctions are linked to the discreteness of phonological form using the mathematics of nonlinear dynamics.

Stability of heartbeat interval distributions in chronic high altitude hypoxia

Recent studies of nonlinear dynamics of the long-term variability of heart rate have identified nontrivial long-range correlations and scale-invariant power-law characteristics (1/f noise) that were remarkably consistent between individuals and were unrelated to external or environmental stimuli (Meyer et al., 1998a). The present analysis of complex nonstationary heartbeat patterns is based on the sequential application of the wavelet transform for elimination of local polynomial nonstationary behavior and an analytic signal approach by use of the Hilbert transform (Cumulative Variation Amplitude Analysis). The effects of chronic high altitude hypoxia on the distributions and scaling functions of cardiac intervals over 24 hr epochs and 4 hr day/nighttime subepochs were determined from serial heartbeat interval time series of digitized 24 hr ambulatory ECGs recorded in 9 healthy subjects (mean age 34 yrs) at sea level and during a sojourn at high altitude (5,050 m) for 34 days (Ev-K2-CNR Pyramid Laboratory, Sagarmatha National Park, Nepal). The results suggest that there exists a hidden, potentially universal, common structure in the heterogeneous time series. A common scaling function with a stable Gamma distribution defines the probability density of the amplitudes of the fluctuations in the heartbeat interval time series of individual subjects. The appropriately rescaled distributions of normal subjects at sea level demonstrated stable Gamma scaling consistent with a single scaled plot (data collapse). Longitudinal assessment of the rescaled distributions of the 24 hr recordings of individual subjects showed that the stability of the distributions was unaffected by the subject’s exposure to a hypobaric (hypoxic) environment. The rescaled distributions of 4 hr subepochs showed similar scaling behavior with a stable Gamma distribution indicating that the common structure was unequivocally applicable to both day and night phases and, furthermore, did not undergo systematic changes in response to high altitude. In contrast, a single function stable over a wide range of time scales was not observed in patients with congestive heart failure or patients after cardiac transplantation. The functional form of the scaling in normal subjects would seem to be attributable to the underlying nonlinear dynamics of cardiac control. The results suggest that the observed Gamma scaling of the distributions in healthy subjects constitutes an intrinsic dynamical property of normal heart function that would not undergo early readjustment or late acclimatization to extrinsic environmental physiological stress, e.g., chronic hypoxia.     

Dynamics of time discrimination: II. The effects of multiple impulses.

According to a diffusion generalization model, time discrimination is determined by the frequency and recency of preceding intervals of time. A procedure for studying rapid timing was used to investigate whether pigeons' wait-time responses were sensitive to these factors. In Experiment 1 the number (two or eight) and spacing (consecutive or far apart) of 5-s interfood intervals (called impulses) intercalated in a series of 15-s interfood intervals (nonimpulses) were studied. Experiment 2 was identical to the first but the interfood intervals were increased by a factor of three. Overall, impulses shortened wait times in the next interfood interval. However, several impulses occurring in succession extended the localized effect of an impulse: Wait times following a set of eight-close impulses were slow to recover to preimpulse levels. The results show that linear waiting is only an approximation to the dynamic process, and a process that is sensitive to events in an animal's remote past, such as the diffusion generalization model, provides a better account of rapid timing effects.     

An on site stress workshop for teachers: The creation of a therapeutic group environment

This paper describes an ongoing stress workshop conducted for 5 years in an elementary school. The school was located in an economically deprived area in the Bronx, New York. Similarities and differences between on-site workshops and therapy groups are discussed. The developmental stages of the group and its corresponding issues are analyzed in terms of group process, transference, and resistance. Illustrative vignettes are presented. The positive effects of group dynamic and group therapy interventions on the participating group as well as on nongroup personnel is demonstrated. Suggestions for adapting group therapy methods in school settings are also presented.This paper was presented as a poster at the Annual Conference of the American Group Psychotherapy Association held in Atlanta, Georgia, February 1995.     

BECOMING RELATED: THE EDUCATION OF A PSYCHOANALYST

The author uses a “professional memoir,” a story about his first experiences in clinical work, to illustrate what he believes to be certain fundamental aspects of an analytic attitude. Taking place in a psychiatric hospital, it is meant to highlight the central place of intuition, emotional receptivity, empathy, relatedness—and their inherent dangers—in engaging therapeutically with patients' emotional disturbances. The author postulates that these and related aspects of clinical psychoanalysis are not sufficiently emphasized in psychoanalytic training and are often eclipsed by idealizations of psychoanalytic theories and their derivative techniques, third‐party demands for evidence‐based data, preoccupations with neurobiological correlates of experience, etc. Despite the clinical fact that psychoanalysis can be extraordinarily helpful to patients, he questions whether clinical psychoanalysis is rightly regarded as a “treatment.”

Influence of Response Similarity on Interference in Perceptual Motor Learning

Motor interference was measured in terms of average response time in sorting 15 pairs of cards, each pair containing words which were either unrelated or identical but printed in different colors. The two words of each pair were used in labeling two cubicles in such a way that they were apart by 0, 1, 2, or 3 intervening cubicles in quasirandomly chosen directions. Interference was inversely related to response similarity, but this relationship may not appear in the absence of sufficient stimulus similarity. The findings are interpreted in the light of a hypothesis which views motor interference as a tendency for responses to deflect from their own courses and be pulled towards those of other responses with which they are at conflict.     

From trainee to trainer: crossing over to the other side of the fence

This article discusses the authors' experiences of the transition from trainee to trainer on a psychotherapeutic training programme, and some of the challenges involved. Using the framework offered by Rizq (2009), the article examines the many parallel processes implicit in the roles of trainee, trainer and therapist. We explore these using examples from personal experience and psychodynamic theory and concepts. We believe our experience illustrates one of the transitions that are inevitable throughout the process of training, qualifying and practising as therapeutic practitioners. These transitions, whilst often fraught with difficulty, are invariably paramount to the process of reflection and development as a practitioner and teacher. Therefore, this article hopes to formulate a deeper understanding of this edifying, yet challenging transition.
