Why are negative behaviours likely to be immediately invoked traits? The effects of valence and frequency on spontaneous trait inferences 下载免费PDF全文
Yuki Shimizu 《Asian Journal of Social Psychology》2017,20(3-4):201-210
People make trait inferences immediately when observing others’ behaviours. Previous studies reported that this spontaneous trait inference (STI) occurs more strongly from negative behaviours than from positive behaviours. However, what is responsible for this negativity bias in STI is unclear. In this study, two experiments investigated the effects of valence (an event's affective positivity or negativity) and frequency (how frequently the behaviour is observed in everyday life) on the occurrence of STI using an adapted version of a savings‐in‐relearning paradigm. Experiment 1 revealed that only valence affected the frequent occurrence of STI. In addition, the instructions to suppress impression formation or to focus attention on an actor's face made no difference to the results. In Experiment 2, the negativity bias in STIs was shown a week after exposure to the behavioural stimuli. These results suggest that the negativity bias in STIs occurs robustly, and the negative valence of observed behaviour is mostly responsible for the negativity bias in STI. The importance of immediate categorization of negative stimuli is discussed in terms of ecological priority. 相似文献

Self-motion perception and vestibulo-ocular reflex (VOR) were studied during whole body yaw rotation in the dark at different static head positions. Rotations consisted of four cycles of symmetric sinusoidal and asymmetric oscillations. Self-motion perception was evaluated by measuring the ability of subjects to manually track a static remembered target. VOR was recorded separately and the slow phase eye position (SPEP) was computed. Three different head static yaw deviations (active and passive) relative to the trunk (0°, 45° to right and 45° to left) were examined. Active head deviations had a significant effect during asymmetric oscillation: the movement perception was enhanced when the head was kept turned toward the side of body rotation and decreased in the opposite direction. Conversely, passive head deviations had no effect on movement perception. Further, vibration (100 Hz) of the neck muscles splenius capitis and sternocleidomastoideus remarkably influenced perceived rotation during asymmetric oscillation. On the other hand, SPEP of VOR was modulated by active head deviation, but was not influenced by neck muscle vibration. Through its effects on motion perception and reflex gain, head position improved gaze stability and enhanced self-motion perception in the direction of the head deviation. 相似文献

Some recent evidence suggests that mental rotation of characters in children aged 7 or 8 years might be lateralized to the left parietal hemisphere. An alternative statement exists, however, the finding might be completely unspecific for mental rotation but either be simply a function of task difficulty or a consequence of the use of characters as stimuli. To test these alternatives, ERPs of 24 second graders were measured twice: (a) during mental rotation with characters as stimuli and orientations of 30°, 90°, or 150° and (b) during memory scanning with characters as stimuli and set sizes of 1, 2, or 3 letters. In both cases, an amplitude modulation was found. The effect of mental rotation as a function of character orientation turned out to be lateralized to the left parietal hemisphere. The effect of memory scanning as a function of set size, however, turned out to be completely non-lateralized. Thus, children's left hemisphere activation during mental rotation is reliable as well as specific. 相似文献

设计并采用“换位体验”的社会互动范式,结合自陈报告法和情感错误归因程序的内隐态度研究范式,通过2个实验比较了面对不同程度的人际伤害,自发性观点采择和语言劝说这两种不同的人际伤害消解方式分别对外显和内隐宽恕的影响。结果发现:无论面对何种程度的人际伤害,(1)与自发性观点采择相比,语言劝说可以有效的促进外显宽恕;(2)自发性观点采择可以有效减少负面内隐态度,促进内隐宽恕,而语言劝说会提高负面内隐态度,阻碍内隐宽恕。该研究结果说明不同人际伤害消解方式对内隐和外显宽恕的影响是不同的,同时也证明了观点采择可以在人际互动中自发产生,并且会对人际关系产生隐性影响。 相似文献

The shoulder internal rotation (IR) and forearm pronation (PR) are important elements for baseball pitching, however, how rapid rotations of IR and PR are produced by muscular torques and inter-segmental forces is not clear. The aim of this study is to clarify how IR and PR angular velocities are maximized, depending on muscular torque and interactive torque effects, and gain a detailed knowledge about inter-segmental interaction within a multi-joint linked chain. The throwing movements of eight collegiate baseball pitchers were recorded by a motion capture system, and induced-acceleration analysis was used to assess the respective contributions of the muscular (MUS) and interactive torques associated with gyroscopic moment (GYR), and Coriolis (COR) and centrifugal forces (CEN) to maximum angular velocities of IR (MIRV) and PR (MPRV). The results showed that the contribution of MUS account for 98.0% of MIRV, while that contribution to MPRV was indicated as negative (−48.1%). It was shown that MPRV depends primarily on the interactive torques associated with GYR and CEN, but the effects of GYR, COR and CEN on MIRV are negligible. In conclusion, rapid PR motion during pitching is created by passive-effect, and is likely a natural movement which arises from 3D throwing movement. Applying the current analysis to IR and PR motions is helpful in providing the implications for improving performance and considering conditioning methods for pitchers. 相似文献

In this study, mental rotation performance was assessed in both an object-based task, human figures and letters as stimuli, and in an egocentric-based task, a human figure as a stimulus, in 60 older persons between 60 and 71 years old (30 women, 30 men). Additionally all participants completed three motor tests measuring balance and mobility. The results show that the reaction time was slower for letters than for both human figure tasks and the mental rotation speed was faster over all for egocentric mental rotation tasks. Gender differences were found in the accuracy measurement, favoring males, and were independent of stimulus type, kind of transformation, and angular disparity. Furthermore, a regression analysis showed that the accuracy rate for object-based transformations with body stimuli could be predicted by gender and balance ability. This study showed that the mental rotation performance in older adults depends on stimulus type, kind of transformation, and gender and that performance partially relates to motor ability. 相似文献

Sex differences in mental rotation were investigated as a function of stimulus complexity with a sample size of N = 72. Replicating earlier findings with polygons, mental rotation was faster for males than for females, and reaction time increased with more complex polygons. Additionally, sex differences increased for complex polygons. Most importantly, however, mental rotation speed decreased with increasing complexity for women but did not change for men. Thus, the sex effects reflect a difference in strategy, with women mentally rotating the polygons in an analytic, piecemeal fashion and men using a holistic mode of mental rotation. 相似文献

The authors examined clockwise and counterclockwise wheel-rotation responses to high- or low-pitched tones presented in participants' (N = 96, Experiment 1; N = 48, Experiment 2; N = 48, Experiment 3) left and right ears. In Experiment 1, a Simon effect (fastest responding when tone location and direction of wheel turn corresponded) was obtained when participants' hands were at the top or middle of the wheel but not at the bottom. With line bottom hand placement, a Simon effect was induced by instructions emphasizing hand movements but not by instructions emphasizing wheel movements (Experiment 2), and by a visual cursor controlled by the wheel but not one triggered by the response (Experiment 3). The results of the experiments showed that the nature of the task and the instructed action goal influence the direction of the Simon effect. 相似文献

In complex three-dimensional mental rotation tasks males have been reported to score up to one standard deviation higher than females. However, this effect size estimate could be compromised by the presence of gender bias at the item level, which calls the validity of purely quantitative performance comparisons into question. We hypothesized that the effect of gender bias at the level of distinct item design features could lead to either an over- or underestimation of reported effect sizes of the gender difference in three-dimensional mental rotation. Using automatic item generation we conducted a series of psychometric experiments in which we independently manipulated one out of four different item design features that have exhibited a gender bias in the previous studies (study 1). This was done in a between-subjects design. The results indicated that gender bias caused by item design features linked to the perceptual stadium of mental rotation led to an overestimation of the effect size of the gender difference while item design features associated with the encoding and transformational stadium resulted in an underestimation of the effect size of the gender difference. In study 2 we tested the hypothesis that the gender difference still remains while controlling for the item design features causing gender bias. The results suggest that a significant portion of the gender difference may be attributable to perceptual and encoding processes involved in mental rotation. 相似文献
