Adopting a powerful posture leads individuals to feel more confident and dominant. Social exclusion can strongly impact individuals' mood and basic social needs. The current research combines these bodies of research, investigating the effects of dominant and submissive poses on responses to social exclusion and inclusion. In two experiments, participants held a slouching or upright pose and were either socially included or excluded using the Cyberball social exclusion manipulation. Social exclusion only affected participants' mood when individuals took a powerful posture: Excluded participants in powerful postures had more negative mood after exclusion than included power‐posing participants, but effects of exclusion and inclusion did not differ among submissive‐posing participants (Experiments 1 and 2). Similarly, it was also found that social exclusion affected basic needs only when participants' adopted powerful poses (Experiment 2). Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

The aim of the present study was to investigate the clinical usefulness of a semi-structured diagnostic parent interview, i.e., the Kiddie-Disruptive Behavior Disorder Schedule (K-DBDS), in preschool children. For Oppositional Defiant Disorder (ODD), to define symptoms two coding methods were compared, i.e., one based on the threshold “often” and the other based on the frequency of behaviors in combination with the presence of clinical concern. For Attention-Deficit/Hyperactivity Disorder (ADHD), to define symptoms, two coding methods were compared, i.e., one with and one without consideration of pervasiveness across contexts. Participants were referred preschool children with externalizing behavioral problems (N?=?193; 83% male) and typically developing (TD) children (N?=?58; 71% male). The referred children were given a diagnosis of either ODD/CD (N?=?39), or ADHD (N?=?58) or comorbid ODD/CD+ADHD (N?=?57) or no diagnosis (N?=?39) based on best-estimate diagnosis. Receiver Operating Characteristic curve analyses showed that a cutoff score of four ODD symptoms using “often” as the threshold for frequency of behaviors led to a sensitivity of 87% and a specificity of 93%; the coding method which included the frequency of behaviors yielded a sensitivity of 56% and a specificity of 100%. For ADHD, a clinical cutoff score of five symptoms without the pervasiveness criterion yielded a sensitivity of 83% and a specificity of 98%; when the pervasiveness criterion was included sensitivity was 77% and specificity 98%. In the clinical assessment of ODD and ADHD in preschool children, the K-DBDS may be used with ODD symptom definition based on the threshold “often” and ADHD pervasiveness across contexts not included. 相似文献

An attempt was made to determine the effects of strength training on elbow flexor stiffness of Down syndrome, non-Down syndrome mentally handicapped, and nonhandicapped subjects. It was hypothesized that stiffness would be affected by the training. Results showed that only half of the individual subjects increased their maximum voluntary contraction (MVC) level as a result of the training and that premeasures and postmeasures of MVC were not significantly different for any of the three groups. As expected, for both premeasures and postmeasures, nonhandicapped subjects had a significantly higher MVC than the other groups who were not significantly different. An important finding was that measures of stiffness (slopes of the IEMG × Torque) were not significantly different for the three groups. This finding is consistant with recent studies (Davis & Kelso, 1982; Shumway-Cook & Woollacott, in press) but raises serious doubts about the popularly held opinion that Down syndrome individuals are hypotonic. It was also found that both the Down syndrome and other mentally handicapped subjects produced significantly less torque at the maximum level than the nonhandicapped subjects. These findings suggest that deficits in mentally handicapping conditions result from a decrease in the range of a primary motor control parameter λ (see Feldman, 1986). 相似文献

Unidirectional positioning movements with spatiotemporal-constraints were examined as a test of impulse-timing theory (Schmidt, 1976; 1980; Wallace, 1981). Movements were examined at the kinematic, kinetic, and neuromuscular levels in three experiments. In the first experiment, displacement was held constant while five different movement times were examined. Both amplitudes and durations of the EMG and the kinetic variables were related to movement time. The results generally support the impulse-timing model. In the second experiment, movements were performed to a target at each of four distances in a constant movement time. EMG and force amplitudes and, unexpectedly, accelerative-force duration were modulated to achieve changes in displacement when movement time was constant. In the third experiment, movement time and displacement were simultaneously varied resulting in four conditions with equal average velocities. The results of this experiment were not as clear and exhibited individual differences. EMG duration did not always vary with changes in movement time. The results of all three experiments could not be adequately accounted for by the impulse-timing model. 相似文献

The authors examined intermanual interactions of 2 hands that were required to concurrently follow trajectories that differed in eccentricity. Ten healthy participants attempted to learn to trace 2 figures, a circle and an ellipse, with bilaterally isochronous (1:1) timing demands. Initial unimanual trials were followed by bilateral practice comprising 750 movement cycles. Two objectives were addressed: The authors' primary aim was to determine if kinematic interlimb interference is evident independent of spatial and temporal interference and to observe the potential practice-related changes in the nature of that interference. That test was afforded by participants' natural tendency to draw a circle with a relatively constant tangential velocity and an ellipse with a systematically varying velocity. A second aim was to observe the nature of spontaneous changes in the performance of each individual effector, and in the relationship between effectors, across practice. Those objectives were specifically addressed in a context in which augmented feedback was not available to direct the learners' attention to a particular feature of performance. The results suggested that interlimb assimilation of spatial features is the primary source of interference for that task and that apparent effects at the kinematic level are the secondary, indirect product of spatial coupling. Those results were found across blocks of practice. With respect to nondirected performance changes, substantially less improvement was evident in the performance of each individual effector than in the reduction of interlimb interference. Specifically, no practice-related changes in temporal variability or velocity bias, and minimal changes in trajectory smoothness, were evident in individual limbs. Conversely, significant reductions were observed in the variability of relative phase between limbs and in the magnitude of interlimb phase lag. 相似文献

Assessment techniques designed to measure adult behavior and mental representation that emphasize relatedness constructs are reviewed. These measures grow out of two traditions, object relations and attachment theories. Although these two paradigms are fairly well elucidated theoretically, the relevant assessment literature is only more recently expanding, especially that focusing directly on adult attachment as opposed to childhood attachment, in addition to a presentation of various projective and objective measures, this review highlights the clinical and research implications for integration of these two paradigms around the cognitive, affective, and behavioral vicissitudes of adult relatedness. 相似文献

Early approaches to projective methods emphasized the use of unstructured materials as stimuli designed to elicit symbolic material within a psychoanalytic framework. Current theorizing concerning projective methods emphasizes the multi-level nature of test behavior and the unique role that projective methods play in the assessment armamentarium. 相似文献

The present study aimed to examine relationships between antisocial personality disorder (APD) symptoms in adulthood and retrospective reports of childhood maltreatment, parental bonding, and teasing, and while controlling for symptoms of depression and anxiety. Four hundred eleven non‐clinical participants (99 males, 312 females), aged 18–65 years, recruited from an Australian university and the general public, completed the questionnaire package. Findings indicated significant associations between childhood maltreatment, parental bonding, teasing, depression, and anxiety, and levels of APD symptomatology. Hierarchical regression analysis revealed that physical abuse, physical neglect, teasing, and level of father care made the largest unique contributions to the prediction of APD scores after statistically controlling for comorbid depression and anxiety. Analysis of variance revealed higher levels of APD symptoms were reported by males and younger participants. This research contributes importantly to our understanding of factors influencing APD symptomatology, with clinical and early intervention implications. 相似文献
