A growing body of research suggests that many voters rely on facial cues from political candidates to elect their leaders. Our study proposes that having a baby face could be an asset for a political candidate in a collectivist culture. Using election bulletin photographs from Taiwan's 2004, 2008 and 2012 legislative election, we look at the extent to which a candidate's baby face is related to election outcomes. Our multilevel modelling includes the number of candidates as Level 1 units, and the number of counties in which the candidates competed as Level 2 units. Vote share is the outcome variable. After considering the candidates' traits (perceived babyfacedness, competence, attractiveness and warmth) and background characteristics, babyfacedness was the strongest predictor of vote share. Results across three elections show consistent patterns: the more babyfaced the candidate, the greater the percentage of votes a candidate received, regardless of the candidate's gender, political affiliation or incumbency status. Babyfacedness is more influential than perceived competence, attractiveness and warmth. 相似文献

Starting in early childhood, children are socialized to be honest. However, they are also expected to avoid telling the truth in sensitive situations if doing so could be seen as inappropriate or impolite. Across two studies (total N = 358), the reasoning of 3- to 5-year-old children in such a scenario was investigated by manipulating whether the information in question would be helpful to the recipient. The studies used a reverse rouge paradigm, in which a confederate with a highly salient red mark on her nose asked children whether she looked okay prior to having her picture taken. In Study 1, children tended to tell the truth only if they were able to observe that the mark was temporary and the confederate did not know it was there. In Study 2, children tended to tell the truth only if they were able to observe that the mark could be concealed with makeup. These findings show that for children as young as age 3, decisions about whether to tell the truth are influenced by the likelihood that the information would be helpful to the recipient. 相似文献

Nairne, Thompson, and Pandeirada (2007) proposed that our memory systems serve an adaptive function and that they have evolved to help us remember fitness-relevant information. In a series of experiments, they demonstrated that processing words according to their survival relevance resulted in better retention than did rating them for pleasantness, personal relevance, or relevance to moving to a new house. The aim of the present study was to examine whether the advantage of survival processing could be replicated, using a control condition that was designed to match the survival processing task in arousal, novelty, and media exposure--the relevance to planning a bank heist. We found that survival processing nonetheless yielded better retention on both a recall (Experiment 1) and a recognition (Experiment 2) test. This mnemonic advantage of survival processing was also obtained when words were rated for their relevance to a character depicted in a video clip (Experiment 3). Our findings provide additional evidence that the mnemonic benefit of survival processing is a robust phenomenon, and they also support the utility of adopting a functional perspective in investigating memory. 相似文献

The effect of visual search efficiency on response preparation: neurophysiological evidence for discrete flow 总被引:1,自引:0,他引:1
Most models assume that response time (RT) comprises the time required for successive processing stages, but they disagree about whether information is transmitted continuously or discretely between stages. We tested these alternative hypotheses by measuring when movement-related activity began in the frontal eye field (FEF) of macaque monkeys performing visual search. Previous work showed that RT was longer when visual neurons in FEF took longer to select the target, a finding consistent with prolonged perceptual processing during less efficient search. We now report that the buildup of saccadic movement-related activity in FEF is delayed in inefficient visual search. Variability in the delay of movement-related activity accounted for the difference in RT between search conditions and for the variability of RT within conditions. These findings provide neurophysiological support for the hypothesis that information is transmitted discretely between perceptual and response stages of processing during visual search. 相似文献

- Consumer acceptance of technological innovations is crucial to marketing new products. According to the most influential model in this area, the Technology Acceptance Model (TAM), perceived usefulness (PU) and perceived ease of use (PEOU) determine users' behavioural intentions to use or purchase a system or product. In the specific context of network externalities, a sense of utility that arises from the number of users (NOU) is considered as important as technology‐specific valuation. This study conducted an empirical survey to examine the effects of TAM and network externalities on the acceptance of Multimedia Messaging Services (MMS), an innovation in the field of mobile telecommunications. The results confirm the effectiveness of the TAM and find that network externalities effect affects users' acceptance to this mobile innovations. Accordingly, the TAM can be applied to predict consumer's acceptance to the mobile telecommunication innovations in the presence of network externalities.

人们在识别自己所熟悉的物体时, 不仅依赖于对输入信息的感知而且还会受到自上而下调节机制的影响。研究者基于功能磁共振成像(fMRI), 利用虚幻探测范式对自上而下字母加工的神经网络进行研究。该研究要求被试从纯噪声(实际没有任何字母)中探测字母。通过对fMRI数据进行心理生理交互效应分析, 发现当被试从纯噪声图片中“看”到字母时, 多个脑区的活动由于受到来自于右侧梭状回的影响而加强。该发现表明自上而下的字母加工网络不但包含负责字母形状和语音加工的脑区, 还涉及一些负责高级认知加工的区域。 相似文献

Experience plays a crucial role in the development of face processing. In the study reported here, we investigated how faces observed within the visual environment affect the development of the face-processing system during the 1st year of life. We assessed 3-, 6-, and 9-month-old Caucasian infants' ability to discriminate faces within their own racial group and within three other-race groups (African, Middle Eastern, and Chinese). The 3-month-old infants demonstrated recognition in all conditions, the 6-month-old infants were able to recognize Caucasian and Chinese faces only, and the 9-month-old infants' recognition was restricted to own-race faces. The pattern of preferences indicates that the other-race effect is emerging by 6 months of age and is present at 9 months of age. The findings suggest that facial input from the infant's visual environment is crucial for shaping the face-processing system early in infancy, resulting in differential recognition accuracy for faces of different races in adulthood. 相似文献
