The aim of the present study was to analyze if the left hemisphere preferentially controls flexion responses toward positive
stimuli, while the right hemisphere is specialized toward extensor responses to negative pictures. To this end, right-handed
subjects had to pull or push a joystick subsequent to seeing a positive or a negative stimulus in their left or right hemifield.
Flexion responses were faster for positive stimuli, while negative stimuli were associated with faster extensions responses.
Overall, performance was fastest when emotional stimuli were presented to the left visual hemifield. This right hemisphere
superiority was especially clear for negative stimuli, while reaction times toward positive pictures showed no hemispheric
difference. We did not find any interaction between hemifield and response type. Neither was there a triple interaction between
valence, hemifield and response type. We suppose that response dichotomies in humans are not as tightly linked to a hemisphere-
and valence-bound reaction type as previously assumed. 相似文献

A series of four experiments investigating gaze behavior and decision making in the context of wayfinding is reported. Participants were presented with screenshots of choice points taken in large virtual environments. Each screenshot depicted alternative path options. In Experiment 1, participants had to decide between them to find an object hidden in the environment. In Experiment 2, participants were first informed about which path option to take as if following a guided route. Subsequently, they were presented with the same images in random order and had to indicate which path option they chose during initial exposure. In Experiment 1, we demonstrate (1) that participants have a tendency to choose the path option that featured the longer line of sight, and (2) a robust gaze bias towards the eventually chosen path option. In Experiment 2, systematic differences in gaze behavior towards the alternative path options between encoding and decoding were observed. Based on data from Experiments 1 and 2 and two control experiments ensuring that fixation patterns were specific to the spatial tasks, we develop a tentative model of gaze behavior during wayfinding decision making suggesting that particular attention was paid to image areas depicting changes in the local geometry of the environments such as corners, openings, and occlusions. Together, the results suggest that gaze during a wayfinding tasks is directed toward, and can be predicted by, a subset of environmental features and that gaze bias effects are a general phenomenon of visual decision making. 相似文献

In this study, the relationship between two aspects of the moral self, moral centrality and internal moral motivation, was analyzed. It is argued that these 2 aspects are conceptually distinct but nonetheless empirically related. Based on a cross-sectional study of 205 adolescents (M age = 14.83 years, SD = 2.21 years) it was found that moral centrality and internal moral motivation, even though substantially correlated, interacted in predicting moral emotion expectancies. Even though moral centrality was unrelated to adolescents' age it predicted a longitudinal increase in internal moral motivation over a 1-year interval. Overall, the findings call for a differentiation of moral centrality and internal moral motivation as 2 distinct but interrelated aspects of moral self-development that follow different developmental trajectories and are differentially related to age. At the same time, the study points out that adolescence may be less important for the development of the moral self than commonly assumed. 相似文献

Previous studies on the impact of perceived threat on confirmatory information search (selective exposure) in the context of decision making have yielded mixed results. Some studies have suggested that confirmatory information search is reduced, yet others have found contradictory effects. The present series of 5 studies consistently found that the crucial moderator for these inconsistent findings was whether the induced threat was contextually related to the subsequent decision and information search tasks. Contextual incongruence (e.g., an induction of terrorist threat followed by an economic decision case) results in reduced levels of confirmatory information search, whereas a congruent threat (e.g., an induction of terrorist threat followed by a decision case on terrorism) results in increased levels of confirmatory information search. Analyses of the underlying psychological processes revealed that decision-unrelated threat inductions increase decision makers' experienced decision uncertainty, thus reducing confirmatory information search. 相似文献

Research on bystander intervention has produced a great number of studies showing that the presence of other people in a critical situation reduces the likelihood that an individual will help. As the last systematic review of bystander research was published in 1981 and was not a quantitative meta-analysis in the modern sense, the present meta-analysis updates the knowledge about the bystander effect and its potential moderators. The present work (a) integrates the bystander literature from the 1960s to 2010, (b) provides statistical tests of potential moderators, and (c) presents new theoretical and empirical perspectives on the novel finding of non-negative bystander effects in certain dangerous emergencies as well as situations where bystanders are a source of physical support for the potentially intervening individual. In a fixed effects model, data from over 7,700 participants and 105 independent effect sizes revealed an overall effect size of g = -0.35. The bystander effect was attenuated when situations were perceived as dangerous (compared with non-dangerous), perpetrators were present (compared with non-present), and the costs of intervention were physical (compared with non-physical). This pattern of findings is consistent with the arousal-cost-reward model, which proposes that dangerous emergencies are recognized faster and more clearly as real emergencies, thereby inducing higher levels of arousal and hence more helping. We also identified situations where bystanders provide welcome physical support for the potentially intervening individual and thus reduce the bystander effect, such as when the bystanders were exclusively male, when they were naive rather than passive confederates or only virtually present persons, and when the bystanders were not strangers. 相似文献

The distinction between data and phenomena introduced by Bogen and Woodward (Philosophical Review 97(3):303–352, 1988) was
meant to help accounting for scientific practice, especially in relation with scientific theory testing. Their article and
the subsequent discussion is primarily viewed as internal to philosophy of science. We shall argue that the data/phenomena
distinction can be used much more broadly in modelling processes in philosophy. 相似文献

Previous research has predominantly focused on negative effects of music exposure by demonstrating that listening to antisocial music increases aggression and aggression-related variables. The present research tests the idea that listening to prosocial (relative to neutral) music decreases aggressive outcomes. In fact, five studies revealed that prosocial music exposure decreased aggressive cognition, affect, and behavior. Mediational analyses showed that the effect of music condition on aggressive behavior was accounted for by differences in aggressive affect. Implications of these results for the predictive validity of the general learning model (Buckley & Anderson, 2006) for the effects of media exposure on social tendencies are discussed. 相似文献

A representative sample of German residents (N = 5397) was surveyed with the aim of studying their acceptance of contemporary rape myths (RMA), using items from the Acceptance of Modern Myths About Sexual Aggression Scale [AMMSA; Gerger et al., 2007] in relation to demographic variables (e.g., gender, age), intolerant belief systems (e.g., sexism, islamophobia), the ideologies of rightwing authoritarianism (RWA), and social dominance orientation (SDO), as well as gender identification. Age showed a U-shaped relationship with RMA, whereas gender was unrelated to RMA. For men (women), greater identification with their gender was associated with higher (lower) RMA. Substantial correlations of RMA with intolerant belief systems support the idea of a schema of intolerance. Although RWA and SDO were both related to RMA, only RWA explained unique variance beyond the effects of intolerant belief systems. Results are discussed in comparison to prior studies using mainly student samples. 相似文献

A controversial concept suggests that impaired finger dexterity in Parkinson’s disease may be related to limb kinetic apraxia that is not explained by elemental motor deficits such as bradykinesia. To explore the nature of dexterous difficulties, the aim of the present study was to assess the relationship of finger dexterity with ideomotor praxis function and parkinsonian symptoms. Twenty-five patients with Parkinson’s disease participated in the study. Their left and right arms were tested independently. Testing was done in an OFF and ON state as defined by a modified version of the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS). Finger dexterity was assessed by a coin rotation (CR) task and ideomotor praxis using a novel test of upper limb apraxia (TULIA), in which the patients were requested to imitate and pantomime 48 meaningless, as well as communicative and tool-related gestures. Coin rotation significantly correlated with TULIA irrespective of the motor state and arm involved, but not with the MDS-UPDRS. This association was significantly influenced by Hoehn and Yahr stage.The strong association of finger dexterity with praxis function but not the parkinsonian symptoms indicates that impaired finger dexterity in Parkinson’s disease may be indeed apraxic in nature, yet, predominantly in advanced stages of the disease when cortical pathology is expected to develop. The findings are discussed within a cognitive-motor model of praxis function. 相似文献
