Increased antagonistic muscle activation during balance recovery has been documented during proprioceptive reliant responses in older adults. The authors examined ankle muscle cocontraction levels in young and older adults during balance recovery from a tether-release-induced, vestibular-input-reliant perturbation. Nine healthy young adult and 9 older women without history of falls performed maximum isometric plantar flexion and dorsiflexion trials followed by balance recovery trials using the ankle strategy. Surface electromyography data normalized to isometric conditions were analyzed during the 100 ms prior to release, the 50 ms immediately after release, and the 100-ms epochs from 100-400 ms following release. No differences existed in gastrocnemius and soleus activity levels (p > .05), though antagonistic tibialis anterior activity was greater in the older adults during the 300-400 ms epoch (young: 23.5 ± 5.8%, older: 38.7 ± 9.4%; p = .001). Vestibular-dominated perturbations may increase antagonistic activity during the recovery phase in older adults, inhibiting efficient balance recovery during proprioceptive and vestibular reliant perturbations. 相似文献

Abstract Intentionality attributions were explored by drawing on the distinction between perfect and imperfect moral duties. Previous research has shown that perfect duty violations carry greater attributional weight than imperfect duty violations (Trafimow & Trafimow, 1999; Trafimow, Bromgard, Finlay, & Ketelaar, 2005). In Studies 1 and 2, the distinction between perfect and imperfect duties was replicated with intentionality judgments, and perfect duty violations received higher intentionality attributions than imperfect duty violations. In Study 3 this effect was reversed by manipulating information about an agent's mental intentions or plans to perform a behavior. That is, participants attributed less intentionality to perfect duty violations compared to imperfect duty violations when a mental intention to perform the behavior was absent. 相似文献

ABSTRACT The present study tested the prediction that male teachers are judged more harshly than female teachers for engaging in heterosexual intercourse with a student. One-hundred and eighty-seven adults (116 women, 71 men) evaluated a hypothetical newspaper article describing an alleged student-teacher relationship as part of a 2 (Gender Dyad: Male Teacher/Female Student or Female Teacher/Male Student) × 2 (Initiator: Student or Teacher) between-subjects design. As expected, a reverse sexual double standard was revealed, in which participants judged situations involving male teachers more harshly than they judged situations involving female teachers, but only when the sexual contact was teacher-initiated. Participants also believed that male students received more social benefits from the sexual contact than did female students. 相似文献

ABSTRACT In a given domain, low-skill individuals typically evaluate the ability level of other people more favorably than high-skill individuals. The current study tests whether this tendency continues to occur even when people have unambiguous distributional information available through which to judge others. Students received distributional information detailing their percentile rank in a statistics course and the percentile rank of another student in the course. Then, students were asked to evaluate their own and the other students' statistics ability. Students evaluated the other person's ability more favorably when their own rank in the course was low rather than high. Therefore, people may use themselves as a standard of comparison when they judge others even when more diagnostic sources of information are available. 相似文献

Differences in adult attachment may concord with differences in social perception. The present study aimed to measure neural activity associated with the presentation of visual social stimuli. In an affective oddball paradigm, event-related brain potentials were recorded while participants viewed negative, positive, and neutral images of people and categorized them according to valence. Brain response amplitudes were examined across valence categories and across attachment groups. Results revealed differences between anxious and avoidant groups in “emotion bias”. The avoidant group displayed a bias towards more neural activation in response to negative compared to positive images. The anxious group trended in the opposite direction. Results are discussed in terms of possible attachment-based differences in motivated attention to social stimuli. 相似文献

Theorists from diverse disciplines purport narrative fiction serves to foster empathic development and growth. In two studies, participants’ subjective, behavioral, and perceptual responses were observed after reading a short fictional story. In study 1, participants who were more transported into the story exhibited higher affective empathy and were more likely to engage in prosocial behavior. In study 2, reading-induced affective empathy was related to greater bias toward subtle, fearful facial expressions, decreased perceptual accuracy of fearful expressions, and a higher likelihood of engaging in prosocial behavior. These effects persisted after controlling for an individual’s dispositional empathy and general tendency to become absorbed in a story. This study provides an important initial step in empirically demonstrating the influence of reading fiction on empathy, emotional perception, and prosocial behavior. 相似文献

Adults and infants can differentiate communicative messages using the nonlinguistic acoustic properties of infant‐directed (ID) speech. Although the distinct prosodic properties of ID speech have been explored extensively, it is currently unknown whether the visual properties of the face during ID speech similarly convey communicative intent and thus represent an additional source of social information for infants during early interactions. To examine whether the dynamic facial movement associated with ID speech confers affective information independent of the acoustic signal, adults' differentiation of the visual properties of speakers' communicative messages was examined in two experiments in which the adults rated silent videos of approving and comforting ID and neutral adult‐directed speech. In Experiment 1, adults differentiated the facial speech groups on ratings of the intended recipient and the speaker's message. In Experiment 2, an original coding scale identified facial characteristics of the speakers. Discriminant correspondence analysis revealed two factors differentiating the facial speech groups on various characteristics. Implications for perception of ID facial movements in relation to speakers' communicative intent are discussed for both typically and atypically developing infants.

Efficient processing of unfamiliar faces typically involves their categorization (e.g., into old vs. young or male vs. female). However, age and gender categorization may pose different perceptual demands. In the present study, we employed functional magnetic resonance imaging (fMRI) to compare the activity evoked during age vs. gender categorization of unfamiliar faces. In different blocks, participants performed age and gender classifications for old or young unfamiliar faces (50% female respectively). Both tasks elicited activations in the bilateral fusiform gyri (fusiform face area, FFA) and bilateral inferior occipital gyri (occipital face area, OFA). Importantly, the same stimuli elicited enhanced activation during gender as compared to age categorization. This enhancement was significant in the right FFA and the left OFA, and may be related to increased configural processing. Our findings replicate and extend recent work, and shows that the activation of core components of the face processing network is strongly dependent on task demands. 相似文献

Many fatal accidents are caused by the driver’s inability, upon the occurrence of sudden events, to detect hazards in time, an ability that is based on the driver’s eye movement patterns, the detection of involved persons, events, objects, as well as the length of time spent on noticing same. This study intends to compare risk perception and decision-making in high-risk traffic situations between individuals with AD and controls by exploring gaze tracking and hazard detection patterns. The study included 16 individuals with early-stage AD and 26 controls. During the experiment, participants underwent several vision and cognitive tests and watched twelve videos of high-risk traffic situations while their eye movement patterns were being recorded by the eye tracking device, in order to understand how cognitive abilities affect eye movement patterns during high-risk traffic situations. The results revealed poorer cognitive abilities and diminished risk perception in individuals with AD compared with the controls and thus an inability to predict potential accidents. In terms of high-risk traffic situations involving pedestrians, traffic violations by others and view-blocking events, a significant difference in gaze patterns was found between individuals with AD and healthy seniors. The contribution of this study is in elaborating the effect of different traffic event type and specific cognitive abilities on traffic risk-detection in individuals with AD. The results of this study may aid in the formulation of driver licensing policies and the design of traffic scenarios; they also elucidate the driving behaviors of individuals with AD. 相似文献
