The aim of this study is to understand adolescent players' satisfaction as a function of parenting styles, players' achievement strategies, and their norm breaking behavior. Finnish 14- and 16-year-old ice-hockey players (n=1018) completed a questionnaire measuring their achievement strategies (SAQ; Nurmi, Salmela--Aro & Haavisto, 1995 b), as well as scales of norm breaking and satisfaction, prepared for the present study. The parents (n=979) filled in scales measuring their parenting styles (CRPR; Pulkkinen, 1996) and attitudes towards norm breaking. Results revealed that players from authoritative families who showed a high level of mastery-orientation expressed high satisfaction in playing ice hockey. Results also showed negative associations between authoritative parenting and both task irrelevant and norm breaking behavior. Parents with parental stress and those with authoritarian parenting styles showed positive attitudes to norm breaking behavior, and players from authoritarian and parental stress homes showed norm breaking behavior in ice hockey. There was no association between norm breaking behavior and player satisfaction. Our results contribute to the planning of a coaching system that serves more educational and developmental purposes, and that encourages the desire to play ice hockey as a hobby.  相似文献

We report two studies on rapid serial naming (RSN). Study 1 addressed the relations among RSN tasks comprising different stimuli. Separate components for RSN of alphanumeric and non-alphanumeric stimuli, as well as for tasks in which the stimuli alternated between categories were identified. In Study 2, phonological skills, processing speed, motor dexterity, and verbal fluency were found to explain RSN performance. The studies indicate: (1) that RSN tasks vary in their properties according to the stimuli used and according to the way the tasks are arranged, and (2) that RSN tasks are multi-componented.  相似文献

Low sensitivity to amplitude modulated (AM) sounds is reported to be associated with dyslexia. An important aspect of amplitude modulation cycles are the rise and fall times within the sound. In this study, simplified stimuli equivalent to just one cycle were used and sensitivity to varying rise times was explored. Adult participants with dyslexia or compensated dyslexia and a control group performed a detection task with sound pairs of different rise times. Results showed that the participants with dyslexia differed from the control group in rise time detection and a correlation was found between rise time detection and reading and phonological skills. A subgroup of participants with lower sensitivity to rise time detection characterized by low accuracy in syllable-level phonological skills was found within the dyslexic group. Short stimuli containing only one rise time produced associations with phonological skills and reading, even in a language where the perception of rise time contrasts are not crucial for the signaling of phonemic contrast.  相似文献

The psychometric properties of a Swedish translation of Spreitzer's (1995a) empowerment scale were assessed. Three parallel assessments were made of data from 1,107 female registered nurses, 758 female assistant nurses, and 107 male registered and assistant nurses. The analyses indicated that the psychometric properties of the scale can be considered satisfactory. Suggestions are made regarding future research in the fields of psychometrics and work- and health-psychology.  相似文献

Five-year changes in episodic and semantic memory were examined in a sample of 829 participants (35-80 years). A cohort-matched sample (N=967) was assessed to control for practice effects. For episodic memory, cross-sectional analyses indicated gradual age-related decrements, whereas the longitudinal data revealed no decrements before age 60, even when practice effects were adjusted for. Longitudinally, semantic memory showed minor increments until age 55, with smaller decrements in old age as compared with episodic memory. Cohort differences in educational attainment appear to account for the discrepancies between cross-sectional and longitudinal data. Collectively, the results show that age trajectories for episodic and semantic memory differ and underscore the need to control for cohort and retest effects in cross-sectional and longitudinal studies, respectively.  相似文献

To investigate whether learning to discriminate between visual compound stimuli depends on decomposing them into constituting features, hens were first trained to discriminate four features (red, green, horizontal, vertical) from two dimensions (colour, line orientation). After acquisition, hens were trained with compound stimuli made up from these dimensions in two ways: a separable (line on a coloured background) stimulus and an integral one (coloured line). This compound training included a reversal of reinforcement of only one of the two dimensions (half-reversal). After having achieved the compound stimulus discrimination, a second dimensional training identical to the first was performed. Finally, in the second compound training the other dimension was reversed. Two major results were found: (1) an interaction between the dimension reversed and the type of compound stimulus: in compound training with colour reversal, separable compound stimuli were discriminated worse than integral compounds and vice versa in compound training with line orientation reversed. (2) Performance in the second compound training was worse than in the first one. The first result points to a similar mode of processing for separable and integral compounds, whereas the second result shows that the whole stimulus is psychologically superior to its constituting features. Experiment 2 repeated experiment 1 using line orientation stimuli of reversed line and background brightness. Nevertheless, the results were similar to experiment 1. Results are discussed in the framework of a configural exemplar theory of discrimination that assumes the representation of the whole stimulus situation combined with transfer based on a measure of overall similarity.  相似文献

Recent findings are reviewed indicating that upper alpha oscillations - when analyzed with appropriate time/ frequency resolution - show a similar physiological reactivity as theta in working memory tasks. Comparable to theta, a load dependent increase in power can be observed during retention and increased evoked activity during retrieval. During retrieval attempts theta behaves like a traveling wave spreading from anterior to posterior sites. During actual retrieval, however, evoked upper alpha becomes transiently nested in theta. We suggest that theta reflects working memory functions whereas upper alpha may be important for the reactivation of long-term memory codes in short-term memory.  相似文献

The sensorimotor transformations necessary for generating appropriate motor commands depend on both current and previously acquired sensory information. To investigate the relative impact (or weighting) of visual and haptic information about object size during grasping movements, we let normal subjects perform a task in which, unbeknownst to the subjects, the object seen (visual object) and the object grasped (haptic object) were never the same physically. When the haptic object abruptly became larger or smaller than the visual object, subjects in the following trials automatically adapted their maximum grip aperture when reaching for the object. This adaptation was not dependent on conscious processes. We analyzed how visual and haptic information were weighted during the course of sensorimotor adaptation. The adaptation process was quicker and relied more on haptic information when the haptic objects increased in size than when they decreased in size. As such, sensory weighting seemed to be molded to avoid prehension error. We conclude from these results that the impact of a specific source of sensory information on the sensorimotor transformation is regulated to satisfy task requirements.  相似文献

We tested the influence of two horizontally aligned visual landmarks on pointing movements to memorized targets, to investigate whether the visuomotor system can make use of an egocentric representation unaffected by visual context. The endpoints of pointing movements were systematically distorted toward the nearest visual landmark, indicating that spatial representations included both target and nontarget information. These distortions were not due to the presence of the landmarks during the movement but, rather, to their presence in the encoding phase. Qualitatively similar distortions were present even with the shortest possible retention phase, when the target was extinguished at movement onset. Finally, we found the same pattern of distortion when participants were forced to remember the target within an allocentric frame of reference. We argue that even early memory representations for pointing movements are influenced by visual information in the surrounding visual field.  相似文献

A statement of the professional umbrella society DGPT is presented that was formulated in cooperation with the various professional societies and with the German Society of Psychosomatic Medicine and Psychotherapy and the Society of Child and Adolescent Therapy. The statement is a reaction to the public claim for effective evidence of psychotherapy and takes the opportunity for a comprehensive presentation of this field. In the introduction Alf Gerlach, as chairman of the umbrella society at the time of the formulation of this statement and now executive chairman responsible for coordinating research, describes the history of the development of the statement.There were two particular moments prompting this statement. On the one hand the Scientific Advisory Board for Psychotherapy as an advisory committee based on the law of psychotherapy, has presented demands for effective evidence that are incompatible with psychoanalysis. Thus, the recognition of psychoanalysis as a treatment method for illnesses was put in doubt. On the other hand, a suggestion was put forward to the Board to recognize psychodynamic psychotherapy as an independent entity. This questioned the unity of the psychotherapeutic field.The statement was passed onto the Scientific Advisory Board last autumn. It is intended for a professional audience and includes answers to important issues of this field. It will have an important role to play in future discussions about professional politics. For this reason, we have decided to begin the present issue of our journal with this statement and thus to open a wide discussion forum.
