This article describes the Subjective Screening of Stuttering (SSS): research edition that is designed to quantify the selected self-reports of people who stutter (PWS) prior to, during, and following their treatment. The three areas screened by the SSS are perceived stuttering severity, the level of internal or external locus of control, and reported word or situation avoidance. Each of the areas has two or three items rated for three audiences on a one to nine rating scale. Other available measures were reviewed and the need for a single instrument that provides quantified screening of each of the areas was recognized. Results of a research project using the SSS with 16 PWS indicated that percent of syllables stuttered correlated with stuttering severity (r=0.75) and with locus of control (r=0.43) but did not correlate with avoidance. These results were interpreted to indicate a need for other types of therapy following the experimental treatment studied. Reliability and validity of the SSS were judged adequate for research and clinical screening. The possible role of screening self-reports of PWS in combination with more extensive self-report instruments and with objective measures of stuttering is discussed. EDUCATIONAL OBJECTIVES: The reader will be able to (1) assess the perception of stuttering severity, avoidance and locus of control of people who stutter (PWS), and (2) determine from the PWS the self-reported outcome of treatment. 相似文献

We exposed standing participants to optic flow in a moving room. Motion sickness was induced by motion that simulated the amplitude and frequency of standing sway. We identified instabilities in displacements of the center of pressure among participants who became sick; these instabilities occurred before the onset of subjective motion sickness symptoms. Postural differences between Sick and Well participants were observed before exposure to the nauseogenic stimulus. During exposure to the nauseogenic stimulus, sway increased for participants who became sick but also for those who did not. However, at every point during exposure sway was greater for participants who became motion sick. The results reveal that motion sickness is preceded by instabilities in displacements of the center of pressure. 相似文献

Various object properties are perceptible by wielding. We asked whether the dynamics of wielding differed as a function of the to-be-perceived property. Wielding motions were analyzed to determine if they differed under the intention to perceive or not perceive rod length (experiment 1), to perceive object height versus object width (experiment 2), and to perceive the length forward of where the rod was grasped versus the position of the grasp (experiment 3). Perceiving these different properties is known to depend on different components of the object's inertia tensor. Analyses of the subtle recurrent patterns in the phase space of the hand motions revealed differences in wielding across the different perceptual intentions. Haptic exploratory procedures may exhibit distinct exploratory dynamics. 相似文献

We examined the effects of crossing different degrees of cooperation and competition on inphase and antiphase 1:1 frequency locked coordination of left- and right-hand-oscillated pendulums. Degree of cooperation was manipulated through the joint frequency of oscillation specified by a metronome (the higher the frequency, the weaker the cooperation), and degree of competition by length (and, therefore, preferred frequency) differences between the two pendulums (the greater the difference, the stronger the competition). Increasing competition was accompanied by either decreasing cooperation (for six participants) or increasing cooperation (for six different participants). On each trial, a participant attempted to produce a steady-state phase relation phi for a given combination of competition and cooperation. Numerical simulations of the extended Haken-Kelso-Bunz (HKB) equation were used to predict (a) the patterns of shift in phi from either 0 or pi radians due to the different competition-cooperation relations and (b) the patterns of variability in phi. It was expected that the HKB equation would be successful in respect to (a), which it was, but not in respect to (b). The observed failure to confirm (b) was expected from the variability due to the different nonharmonic dynamics of the component oscillators, a source of variability not included in the HKB equation. The experimental results together with simulations and analyses of the phase-plane trajectories of the component oscillators suggest the operation of deterministic in addition to stochastic variability in the phase relation of contralateral limbs. 相似文献

From both direct-realist and motor-theoretic perspectives, the objects of speech perception are construed as articulatory events. We offer the alternative view that it is the auditory properties of phonetic events to which listeners are primarily sensitive. Evidence for this alternative view comes from a variety of sources, including studies of phonetic and phonological universals, comparisons of the perception of speech and nonspeech signals, cross-language perceptual experi- ments, and studies of phonetic categorization by nonhuman animals. 相似文献

Relationships with peers and adults are expected to foster social responsibility in physical activity-based positive youth development programs. Low-income youth (N = 479) were surveyed pre- and post-program.Psychometric properties of a new social responsibility scale were supported. Belonging predicted changes in social responsibility, and leader emotional support moderated the autonomy support- and belonging-social responsibility associations. Those with higher leader emotional support had a stronger positive association between autonomy support and social responsibility. Those with lower leader emotional support had a stronger positive association between belonging and social responsibility. Positive social relationships with peers and staff may facilitate social responsibility. 相似文献

This essay introduces the themes that motivate the three articles that follow. Their common aim is to explore the connections between the Earth Charter and the concept of biodemocracy with the intention of highlighting ways of thinking about the relationship between science, religion, and the environment in the twenty‐first century. Informed by the science of ecology and written by scholars of religion, the articles included here seek to integrate movements and ideas as diverse as postmodern thought, the much‐debated thought of Lynn White, jr. (his preferred spelling), and the synergy emerging between the Earth Charter and Journey of the Universe. 相似文献

When fetal alcohol syndrome (FAS) was initially described, diagnosis was based upon physical parameters including facial anomalies
and growth retardation, with evidence of developmental delay or mental deficiency. Forty years of research has shown that
FAS lies towards the extreme end of what are now termed fetal alcohol spectrum disorders (FASD). The most profound effects
of prenatal alcohol exposure are on the developing brain and the cognitive and behavioral effects that ensue. Alcohol exposure
affects brain development via numerous pathways at all stages from neurogenesis to myelination. For example, the same processes
that give rise to the facial characteristics of FAS also cause abnormal brain development. Behaviors as diverse as executive
functioning to motor control are affected. This special issue of Neuropsychology Review addresses these changes in brain and behavior highlighting the relationship between the two. A diagnostic goal is to recognize
FAS as a disorder of brain rather than one of physical characteristics. 相似文献

The study investigated how children with heavy prenatal alcohol exposure regulate movement speed and accuracy during goal-directed movements. 16 children ages 7 to 17 years with confirmed histories of heavy in utero alcohol exposure, and 21 nonalcohol-exposed control children completed a series of reciprocal tapping movements between two spatial targets. 5 different targets sets were presented, representing a range of task difficulty between 2 and 6 bits of information. Estimates of percent error rate, movement time, slope, and linear fit of the resulting curve confirmed that for goal-directed, reciprocal tapping responses, performance of the group with prenatal alcohol exposure was described by a linear function, as predicted by Fitts' law, by sacrificing movement accuracy. The index of performance was the same for the two groups: it initially increased, then leveled off for more difficult movements. 相似文献
