Intuitive understanding of the relation between velocities and masses in simulated collisions

The participants in our experiments were asked to judge whether simulated horizontal collisions appeared to be “natural” or “unnatural”. We manipulated the implied masses and the velocity ratio of two colliding objects. Implied masses were varied through manipulations of the objects' simulated materials (Experiment 1) and sizes (Experiments 2 and 3). For each participant, we determined the interval of velocity ratios that produced “natural” responses most of the time and evaluated how this interval varied as a function of implied masses. The results revealed a fair degree of consistency between predictions of Newtonian mechanics and the participants' responses; this consistency was greater when the implied masses of the colliding objects were varied through manipulations of the simulated materials. Overall, the results support the hypothesis that the cognitive system can integrate multiple sources of stimulus information, enabling individuals to understand multidimensional mechanical events.     

“Avoiding or approaching eyes”? Introversion/extraversion affects the gaze-cueing effect

We investigated whether the extra-/introversion personality dimension can influence processing of others’ eye gaze direction and emotional facial expression during a target detection task. On the basis of previous evidence showing that self-reported trait anxiety can affect gaze-cueing with emotional faces, we also verified whether trait anxiety can modulate the influence of intro-/extraversion on behavioral performance. Fearful, happy, angry or neutral faces, with either direct or averted gaze, were presented before the target appeared in spatial locations congruent or incongruent with stimuli’s eye gaze direction. Results showed a significant influence of intra-/extraversion dimension on gaze-cueing effect for angry, happy, and neutral faces with averted gaze. Introverts did not show the gaze congruency effect when viewing angry expressions, but did so with happy and neutral faces; extraverts showed the opposite pattern. Importantly, the influence of intro-/extraversion on gaze-cueing was not mediated by trait anxiety. These findings demonstrated that personality differences can shape processing of interactions between relevant social signals.     

The two sides of the mental clock: the Imaginal HemiSpatial Effect in the healthy brain

When subjects are asked to compare the mental images of two analog clocks telling different times (the mental clock test), they are faster to process angles formed by hands located in the right than in the left half of the dial. In the present paper, we demonstrate that this Imaginal HemiSpatial Effect (IHSE) can be also observed in two modified versions of the mental clock test: in Experiment 1 subjects had to imagine the position occupied by two numbers within a clock face and to judge if the subtended angle was smaller or greater than 90 degrees , while in Experiment 2 subjects were asked to match two imagined positions on a clock face with two visually presented locations. The finding of the IHSE in these tasks suggested that it is a genuine phenomenon related to spatial imagery tasks, and is consistent with recent neuroimaging evidence that the left parietal lobe is mainly involved in the generation of spatial mental images.     

Contextual effects on prejudiced attitudes: When the presence of others leads to more egalitarian responses

In the present paper, we tested the hypothesis that the physical presence of other ingroup members may ameliorate Whites’ spontaneous affective responses toward Blacks. Results of Study 1 demonstrated that IAT-assessed attitudes toward Blacks were indeed less negative when participants were tested in small groups rather than individually. Study 2 shed light on the underlying processes by demonstrating that respondents at the presence of others displayed increased accessibility to egalitarian-related concepts after Black primes, as compared to respondents tested individually. Overall, results point to the wide malleability of spontaneous affective responses and to the possibility that contextual factors, like the presence of other individuals, might automatically activate egalitarians goals. Results are discussed in relation to current models of automatic intergroup bias and preconscious control over it.     

Conservatism as motivated avoidance of affect: Need for affect scales predict conservatism measures

We propose that individual differences in the motivation to avoid emotions are related to political conservatism. We argue that because conservatism is concerned with managing uncertainty and emphasizes ego-control, conservative ideologies match with the motivational concerns of those individuals who find emotions to be uncertainty-enhancing and dysfunctional. In a group of 267 participants, positive associations were found between emotion avoidance and right-wing authoritarianism, social dominance orientation, and support for conservative policies. Negative associations were found between emotion approach and conservatism measures.     

Implicit ingroup metafavoritism: subtle preference for ingroup members displaying ingroup bias

The current article investigated how individuals evaluate ingroup members displaying either ingroup bias or egalitarian intergroup behaviors. The hypotheses predicted that on explicit responses a preference for the egalitarian ingroup member would emerge; in contrast, on more spontaneous and uncontrolled responses, a preference for the ingroup favoritist would result. Across four studies these hypotheses were confirmed for both minimal groups (Studies 1 and 2) and ethnic groups (Studies 3 and 4). Despite a verbal preference for those who behaved in an egalitarian way, an implicit ingroup metafavoritism was found. Overall, results indicated the presence of dual attitudes in the perception of ingroup members and the strict interconnection between intergroup behaviors and intragroup perception.     

Studying, Practicing, and Mastering: A Test of the Model of Goal-Directed Behavior (MGB) in the Software Learning Domain

The present study tested the model of goal-directed behavior (MGB). The model proposes that behavioral intentions to perform instrumental behaviors are primarily motivated by desires to perform the acts. In turn, desires mediate the effects of attitudes, subjective norms, perceived control, and anticipated emotions on intentions. Construct validity for MGB variables is assessed, and the predictive utility of the MGB is compared with that of the theory of planned behavior (TPB). College students ( N = 102) provided measures for MGB and TPB variables while participating in a training program to use statistical software. We focused on two goal-related instrumental behaviors: studying handbooks and practicing with the package. The results show that the MGB accounts for a greater proportion of variance in intentions and instrumental behaviors than does TPB. Although desires mediate most of the effects of other predictors on intentions to perform the instrumental behaviors, it is proposed that when the behavior is normatively relevant, or when self-efficacy appraisals play a major role, subjective norms and perceived behavioral control may directly affect intentions.     

I Will Put My Law in Their Minds: Social Control and Cheating Behavior Among Catholics and Protestants

Catholics and Protestants differ in terms of social autonomy versus heteronomy. We propose that the regulation of behavior in accordance with social norms depends on the social control exercised by an authority for Catholics more than it does for Protestants. Two experiments measured cheating behavior (the transgression of a social norm) as a function of the religious group (Protestant vs. Catholic) and social control (with vs. without). Catholics were found to be more responsive to social control, that is, to cheat less when social control was salient, whereas Protestants' behavior did not depend on this dimension. In Study 2, intrinsic‐extrinsic religiousness was found to mediate this difference. Results are discussed in the context of the effects of public policies based on social control.
