Young Tennis Players’ Competitive Task Involvement and Performance: The Role of Goal Orientations,Contextual Motivational Climate,And Coach-Initiated Motivational Climate

The purpose of this study was to examine the role of situational and dispositional factors in contributing to competitive task involvement and performance in young tennis players. One hundred fifty-one adolescent tennis players and their coaches participated in the study. Participants responded to instruments measuring pre-game dispositional goal orientations and perceptions of the motivational climate and post-game task involvement in the competition by assessing concentration, loss of self-consciousness, and autotelic experience, perceptions of coach-initiated motivational climate in competition, and self-evaluation of game performance. In addition, coaches evaluated the players’ performance. Results showed that task involvement was predicted by players’ perceptions of a coach-initiated learning motivational climate in competition. Loss of self-consciousness was predicted by the players’ perceptions of a coach-initiated performance climate in competition. Finally, coaches’ and players’ assessment of performance were predicted by autotelic experience, concentration, and by perception of coach-initiated learning and performance orientation in competition.     

Teaching sexuality and Christianity for perspective transformation: Suggested resources and strategies

Sexual activity and desire have often been seen as inimical to Christian spirituality and practice, and many people have come to view Christianity as austere and shaming regarding sexuality. However, sexuality, religion, and policy‐making have become so intertwined, that to ignore how they intersect and affect particular individuals' lives does a disservice to students. This article presents resources and strategies for incorporating the topic of sexuality into liberal undergraduate and graduate theological classrooms. It provides guidance to instructors lacking research expertise in sexuality and focuses on three main pedagogical categories: perspective transformation; embodiment pedagogy; and sexual violence and trauma. One purpose of this article is to generate conversation: there is a need for further collaboration with colleagues who are experts in various disciplines to continue mining resources to offer diverse strategies and resources.     

Reward improves cancellation and restraint inhibition across childhood and adolescence

Inhibitory control allows for the regulation of thought and action and interacts with motivational variables, such as reward, to modify behavior adaptively as environments change. The authors examined the effects of reward on two distinct forms of inhibitory control, cancellation and restraint. Typically developing children and adolescents completed 2 versions of the stop signal task (cancellation and restraint) under 3 reward conditions (neutral, low reward, and high reward), where rewards were earned for successful inhibitory control. Rewards improved both cancellation and restraint inhibition, with similar effects of reward on each form of inhibitory control. Rewards did not alter the speed of response execution in either task, suggesting that rewards specifically altered inhibition processes without influencing processes related to response execution. Adolescents were faster and less variable than children when executing and inhibiting their responses. There were similar developmental effects of reward on the speed of inhibitory control, but group differences were found in terms of accuracy of inhibition in the restraint task. These results clarify how reward modulates two different forms of regulatory behavior in children and adolescents.     

Evidence for linguistic deficit in nonlexical processing in reading. A study of a Spanish-speaking patient

Previous studies have shown that in the so-called opaque languages (those in which spelling does not correspond to pronunciation), there are relatively independent routes for lexical and nonlexical processing, that is, for words and nonwords, both in spoken and in written language. On the other hand, in the so-called transparent languages (those in which pronunciation corresponds to written forms), empirical evidence is scarcer. In this study of a neurological patient (parieto-temporal lesion), speaker of a transparent language (Spanish) showing a specific deficit in nonlexical reading processing, linguistic analysis for words was relatively preserved. This finding suggests the use of various routes in the processing of transparent languages.     

Photoelectric-helicoidal spirometer

This paper describes a photoelectric-helicoidal spirometer that has been designed in our laboratory. It includes a cylindrical helix (or turbine) partitioned in each of its blades by means of opaque plates transversally disposed. These plates obstruct the ray of light emitted by a diode, preventing it from reaching a photoreceptor located at the opposite side of the turbine. These basic elements are located in a module that can be adjusted to a mask that covers nostrils and mouth. Control software for this device is also described. The software facilitates a graphical representation of respiratory activity, as well as its storage in the computer. Software has been designed to be adaptable to any digital-to-analog converter. Both the device and the software have several advantages over traditional spirometers, as well as other nonspirometric techniques for studying respiratory activity.     

Neuropsychological evidence for "word-meaning deafness" in a Spanish-speaking patient

In this paper we present a case of "word-meaning deafness," characterised by serious problems in the comprehension of spoken language, whilst repetition and writing words and non-words from dictation are preserved. This performance indicates the impossibility of correctly accessing phonological representation from the semantic representation of words. Neuropsychological evidence on specific alterations in word-meaning disorders is scarce, and this study contributes new findings with a Spanish-speaking patient. The nature of the processes involved in understanding language and the cerebral mechanisms that might be affected in each case were discussed, in accordance with current neuropsychological theories.     

Active and passive distraction using a head-mounted display helmet: effects on cold pressor pain in children.

OBJECTIVE: The current study tested the effectiveness of interactive versus passive distraction that was delivered via a virtual reality type head-mounted display helmet for children experiencing cold pressor pain. DESIGN: Forty children, aged 5 to 13 years, underwent 1 or 2 baseline cold pressor trials followed by interactive distraction and passive distraction trials in counterbalanced order. MAIN OUTCOME MEASURES: Pain threshold and pain tolerance. RESULTS: Children who experienced either passive or interactive distraction demonstrated significant improvements in both pain tolerance and pain threshold relative to their baseline scores. In contrast, children who underwent a second cold pressor trial without distraction showed no significant improvements in pain tolerance or threshold. CONCLUSION: Although both distraction conditions were effective, the interactive distraction condition was significantly more effective. Implications for the treatment of children's distress during painful medical procedures are discussed.     

On the Nature of Nonverbal Working Memory Fractionation: A Case of Selective Spatial Short-Term Memory Deficit in a Child

Several lines of research on adult subjects demonstrate a visual/spatial fractionation of nonverbal working memory (WM), while behavioral studies on normal children support the idea of a static/dynamic distinction. In the present paper, we report a child (Z.M.) who failed on nonverbal WM tasks. To verify the nature of his defect, we carried out two experiments: in Experiment 1, Z.M. failed on spatial WM tasks but not on visual WM tasks and was not affected by the static/dynamic format of stimulus presentation; in Experiment 2, this visual/spatial dissociation was extended to the imagery domain. These results are best accounted for within the visual/spatial fractionation of WM and confirmed the role of WM in mental imagery. Clinical and rehabilitative implications of the present findings are also discussed.     

The Impact of Impairment Criteria on Rates of ADHD Diagnoses in Preschoolers

Behaviors characteristic of ADHD are common among preschool children, and as such, their clinical significance is oftentimes difficult to ascertain. Thus a focus on impairment is essential in determining the clinical significance of these behaviors. In order to explore the impact of impairment criteria on rates of diagnoses in inattentive/hyperactive children aged 36 through 60-months-old, we first developed, and psychometrically evaluated, the Children's Problem Checklist (CPC) which was designed to assess psychosocial impairment associated with ADHD in a community sample of preschoolers (n = 394), and found its reliability and validity to be acceptable. We then examined the impact of the inclusion of various CPC-determined impairment criteria, over and above symptom criteria measured by the ADHD-RS-IV, using various cut points ranging from the 75th to 90th percentile of our community sample. This reduced the number of children meeting criteria for ADHD by 46-77%. These findings are discussed in terms of the importance of using impairment criteria, rather than just severity of inattention, impulsivity and hyperactivity, when diagnosing ADHD in preschool children.     

The tell-tale heart: physiological reactivity during resolution of ambiguity in youth anxiety

In the past decade, cognitive biases and physiological arousal have each been proposed as mechanisms through which paediatric anxiety develops and is maintained over time. Preliminary studies have found associations between anxious interpretations of ambiguity, physiological arousal, and avoidance, supporting theories that link cognition, psychophysiology, and behaviour. However, little is known about the relationship between youths’ resolutions of ambiguity and physiological arousal during acute stress. Such information may have important clinical implications for use of verbal self-regulation strategies and cognitive restructuring during treatments for paediatric anxiety. In this brief report, we present findings suggesting that anxious, but not typically developing, youth select avoidant goals via non-threatening resolution of ambiguity during a stressor, and that this resolution of ambiguity is accompanied by physiological reactivity (heart rate, heart rate variability, and respiratory sinus arrhythmia). We propose future empirical research on the interplay between interpretation bias, psychophysiology, and child anxiety, as well as clinical implications.
