Relations between voting choice and similarity in traits between voters and political candidates are examined in two studies. The first study was conducted in Spain, where the personalities of Mariano Rajoy and José Luis Rodríguez Zapatero were assessed. The second study was conducted in Italy, where the politicians assessed were Walter Veltroni and Silvio Berlusconi. Results show in both cases a similarity between voters' self-reported personality and their appraisals of the leaders of the party for which they voted. Similarity is generally higher with respect to traits that are the most distinctive for each platform and its leader. The findings show a higher similarity between voters and their leaders on the markers of agreeableness, such as "loyal" and "sincere." Findings hold across countries and political figures, demonstrating the role that personal characteristics of both voters and candidates play in orienting political preference. 相似文献

Many studies have investigated infant smiling behaviour during wake and active sleep. In the majority of studies authors agreed that two month-old infants exhibit social smiles. However it is not clear if newborns exhibit different kinds of smiles during wake and active sleep to two month-old infants and if the communicative context can affect the quantity and quality of these smiles.The aim of this study was to test if different kinds of communication affects the amount and the quality of smiles during different behavioural states.Smiling behaviour was analyzed during interactive wake (IW) and active sleep (AS), in 40 newborns randomly assigned to 4 groups of 10 newborns each: continuous tactile communication group, discontinuous non periodic tactile communication group, discontinuous periodic tactile communication group, absent communication group. In the total sample the open/closed mouth (social/non social) smiles ratio was 38/5 during IW and 1/28 during AS (p < .001). Moreover these ratios were different between the four groups.Different kinds of tactile communication affect amount and quality of the smiles of newborns during IW and AS. Moreover the morphological difference of the smiles during IW and AS suggested that for newborns the smiling behaviour during IW could have a social meaning, as it does for two month-old infants. 相似文献

The influence of stable individual differences on behaviour need not solely rely upon deliberative processes but can also be exerted through automatic associative processes. In this contribution, three studies that illustrate the role of individual differences in automaticity are presented in the domain of helping behaviour. The first study provides evidence both for a double dissociation and for an additive pattern of implicit and explicit measures in predicting relevant altruistic behaviours. The subsequent two studies show that when the concept of altruism is subliminally primed, individual differences in implicit attitudes significantly predict behaviour. The results are in line with the gatekeeper model, and their implications are discussed focusing on the key role of individual differences in modulating automaticity effects.

Mapping of number onto space is fundamental to mathematics and measurement. Previous research suggests that while typical adults with mathematical schooling map numbers veridically onto a linear scale, pre-school children and adults without formal mathematics training, as well as individuals with dyscalculia, show strong compressive, logarithmic-like non-linearities when mapping both symbolic and non-symbolic numbers onto the numberline. Here we show that the use of the linear scale is dependent on attentional resources. We asked typical adults to position clouds of dots on a numberline of various lengths. In agreement with previous research, they did so veridically under normal conditions, but when asked to perform a concurrent attentionally-demanding conjunction task, the mapping followed a compressive, non-linear function. We model the non-linearity both by the commonly assumed logarithmic transform, and also with a Bayesian model of central tendency. These results suggest that veridical representation numerosity requires attentional mechanisms. 相似文献

The adaptive calibration model (ACM) is an evolutionary-developmental theory of individual differences in stress responsivity. In this article, we tested some key predictions of the ACM in a middle childhood sample (N = 256). Measures of autonomic nervous system activity across the sympathetic and parasympathetic branches validated the 4-pattern taxonomy of the ACM via finite mixture modeling. Moreover, the 4 patterns of responsivity showed the predicted associations with family stress levels but no association with measures of ecological stress. Our hypotheses concerning sex differences in responsivity were only partly confirmed. This preliminary study provides initial support for the key predictions of the ACM and highlights some of the methodological challenges that will need to be considered in future research on this topic. 相似文献

This article discusses 3 ways in which adaptive developmental mechanisms may produce maladaptive outcomes. First, natural selection may favor risky strategies that enhance fitness on average but which have detrimental consequences for a subset of individuals. Second, mismatch may result when organisms experience environmental change during ontogeny, for instance, because they move from one environment to another. Third, organisms may learn about their environment in order to develop an appropriate phenotype; when cues indicate the environmental state probabilistically, as opposed to deterministically, sampling processes may produce mismatch. For each source of maladaptation, we present a selection of the relevant empirical research and illustrate how models from evolutionary biology can be used to make predictions about maladaptation. We also discuss what data can be collected to test these models in humans. Our goal is to show that evolutionary approaches not only yield insights into adaptive outcomes but can also illuminate the conditions leading to maladaptation. This perspective provides additional nuance to the dialectic between the developmental psychopathology model and evolutionary developmental psychology. 相似文献

To become cooperative members of their cultural groups, developing children must follow their group's social norms. But young children are not just blind norm followers, they are also active norm enforcers, for example, protesting and correcting when someone plays a conventional game the "wrong" way. In two studies, we asked whether young children enforce social norms on all people equally, or only on ingroup members who presumably know and respect the norm. We looked at both moral norms involving harm and conventional game norms involving rule violations. Three-year-old children actively protested violation of moral norms equally for ingroup and outgroup individuals, but they enforced conventional game norms for ingroup members only. Despite their ingroup favoritism, young children nevertheless hold ingroup members to standards whose violation they tolerate from outsiders. 相似文献

The classic bystander effect stipulates that people help others more when they are alone than when other bystanders are present. We reason that, sometimes, the presence of bystanders can increase helping, notably in situations where public self-awareness is increased through the use of accountability cues (e.g., a camera). We conducted two experiments in which we tested this line of reasoning. In both experiments, participants read messages soliciting support in an online forum. We varied the number of people that were present in that forum to create a bystander and an alone condition. In Study 1, we introduced an accountability cue by making participants' screen-names more salient, and in Study 2, we used a webcam. Both studies indicate that, as expected, the bystander effect can be reversed by means of cues that raise public self-awareness in social settings. 相似文献

In Evaluative Conditioning (EC) studies, novel Conditioned Stimuli (CSs) are usually selected so to be neutral. However, in real life, because of the tendency of humans to evaluate novel stimuli automatically, novel CSs are very often initially valenced. From the literature little is known on whether EC can be successful under these conditions. In this contribution we applied a specific EC paradigm, namely self-referencing (SR) task, to new fictitious social groups. We present three studies. The first preliminary study is a pretest for selecting novel CSs. We examined the valence of four fictitious novel groups with both direct (semantic differential) and indirect (IAT) measures. The results showed that one pair was neutral (Lerriani vs. Dattiani) and the other was valenced (Niffiani, CS+ vs. Duppiani, CS?). In the second and third studies, we applied the SR paradigm to the neutral and initially valenced CSs. The results revealed a significant EC effect on both indirect and direct measures, such that the groups associated with the self became more positive and the groups associated with the other became more negative. The effects were found for both neutral and initially valenced groups, therefore showing that neutrality is not a prerequisite for EC effects. If anything, the effects were stronger for the initially valenced groups, especially on the indirect measure. Results are discussed in light of the detection of EC effects for both neutral and initially valenced CSs. 相似文献
