An important question in the field of imitation is what information is used for movement reproduction. While it is argued that relative motion information is perceived and minimised, direct evidence is lacking. In this experiment relative motion was manipulated to convey a novel kicking action. Twenty-four adults were assigned to one of the three impoverished relative motion display groups showing only the TOE, FOOT or LEG. After practise with partial information, participants watched a full-body display and in a final condition performed the action with an additional context constraint (i.e., a ball). Movement kinematics were collected and difference scores between participants and the model were analysed. The groups did not differ in terms of knee-ankle coordination. For hip-knee, the TOE group performed more like the model than the FOOT and LEG group. When transferred to the full-body display, there were no significant improvements. End-point trajectory information can provide sufficient information to reproduce key characteristics of the movement form. 相似文献

Abstract— Three studies investigated the effects of self-construal activation on behavior conducive to interpersonal proximity. Study 1 revealed that compared with control participants, participants who were primed with the independent (or personal) self sat further away from where they anticipated another person would sit in a waiting room. Results of Study 2 indicated that participants primed with the interdependent (or social) self sat closer to the anticipated other person than did those primed with the independent self. Finally, Study 3 used the chronic self-construal of participants to predict the seating distance in dyadic settings. Results showed that greater independence of participants' self-construals was associated with greater spatial distance during the interaction. Together, the studies provide clear evidence that self-construal activation automatically influences interpersonal behavior as reflected in the actual distance between the self and others. Results are discussed in terms of the functions and motives connected to self-construals. 相似文献

The split fovea theory proposes that visual word recognition of centrally presented words is mediated by the splitting of the foveal image, with letters to the left of fixation being projected to the right hemisphere (RH) and letters to the right of fixation being projected to the left hemisphere (LH). Two lexical decision experiments aimed to elucidate word recognition processes under the split fovea theory are described. The first experiment showed that when words were presented centrally, such that the initial letters were in the left visual field (LVF/RH), there were effects of orthographic neighborhood, i.e., there were faster responses to words with high rather than low orthographic neighborhoods for the initial letters ('lead neighbors'). This effect was limited to lead-neighbors but not end-neighbors (orthographic neighbors sharing the same final letters). When the same words were fully presented in the LVF/RH or right visual field (RVF/LH, Experiment 2), there was no effect of orthographic neighborhood size. We argue that the lack of an effect in Experiment 2 was due to exposure to all of the letters of the words, the words being matched for overall orthographic neighborhood count and the sub-parts no longer having a unique effect. We concluded that the orthographic activation found in Experiment 1 occurred because the initial letters of centrally presented words were projected to the RH. The results support the split fovea theory, where the RH has primacy in representing lead neighbors of a written word. 相似文献

Two technologies are currently used to screen newborn infants for hearing, auditory brainstem response (ABR), and otoacoustic emissions (OAEs). Each technology is based on detecting the infant's physiologic response to auditory stimulation. ABR is a short-latency auditory evoked response originating from eighth nerve and brainstem auditory pathway structures and detected by scalp surface electrodes. OAEs are auditory signals generated by cochlear outer hair cells in response to acoustic stimulation and detected by a miniature microphone coupled to the infant's ear. Although each technique requires specific sound generation and response recording technologies, advances in computerized stimulus delivery and response detection algorithms allow these tests to be performed by trained technicians or volunteers under the supervision of an audiologist. Results of test performance, and the advantages and disadvantages of each technique are described. 相似文献

People with an intellectual disability are over-represented in the criminal justice system in many western countries. Identifying accused persons with intellectual disability is important if they are to receive protections available under the law. Accurate diagnosis is also relevant for correctional administrators, probation and parole services, and community services. Diagnosis of intellectual disability must be made on the basis of both cognitive skills (intelligence) and adaptive behavior. In this study, the Kaufman Brief Intelligence Test assessed intelligence, and the Vineland Adaptive Behavior Scales assessed adaptive behavior, through self-report. Tests were administered to 150 offenders, ranging in age from 13 to 53 years, in Australian prisons, juvenile detention centers, legal aid offices, and probation services. Pearson product-moment correlation coefficients calculated among all subtests and between total scores were significant. ROC curve analyses demonstrated that performance on each effectively predicted a standard score of less than 70 on the other one. 相似文献

This study investigated factors that have previously been implicated in male sexual aggression towards women, using a structural equation modelling approach to assess their relative influence on sexually coercive behaviours in young Singaporean men. Variables were classified under three major headings: childhood experience, personality, and attitudes facilitating violence. Non-sexual aggression against women was included in order to investigate its relationship to sexual aggression as well as its own causal antecedents. Results suggest that sexual and non-sexual aggression have different antecedents, and confirm the primacy of sexual variables (sexual experience, child sexual abuse) as antecedents to sexual aggression. Contrary to the hypothesis that sexual aggression is primarily aggressive in motivation, belligerence exerted only indirect effects on sexual aggression. Attitudinal variables (e.g. attitudes supportive of sexual aggression) contributed modestly to sexual but not to non-sexual aggression. Antisociality exerted indirect effects on both sexual aggression (via sexual experience and acceptance of interpersonal violence) and on non-sexual aggression (via belligerence). Parental violence contributed exclusively to non-sexual aggression. Finally, some cross-cultural differences in sexually coercive behaviour are highlighted. 相似文献

We examined the extent to which visual orienting in 8-month-old infants shows evidence of being guided by object-based representations. Infants’ preferences to look at conspicuous targets presented on one of two stationary objects were measured following an event (cue) which directed their covert attention to one of the objects. The results indicate that by 8 months of age a cue presented on one part of an object directs attention to the whole object (object-centered attention). This then affects responses to targets that appear elsewhere on the cued object. 相似文献

Randomization tests are valid alternatives to parametric tests like the t test and analysis of variance when the normality or random sampling assumptions of these tests are violated. Three SPSS programs are listed and described that will conduct approximate randomization tests for testing the null hypotheses that two or more means or distributions are the same or that two variables are independent (i.e., uncorrelated or “randomly associated”). The programs will work on both desktop and mainframe versions of SPSS. Although the SPSS programs are slower on desktop machines than software designed explicitly for randomization tests, these programs bring randomization tests into the reach of researchers who prefer the SPSS computing environment for data analysis. 相似文献
