The effect of the dominance of an in-vehicle agent’s voice on driver situation awareness,emotion regulation,and trust: A simulated lab study of manual and automated driving

As in-vehicle voice agents increase in popularity, related research is extending to how voice messages can affect the driver’s cognitive and emotional states. Accordingly, we investigated how in-vehicle agent (IVA) voice dominance and driving automation can affect the driver’s situation awareness (SA), emotion regulation (ER), and trust. To this end, a lab-based experiment was conducted with a medium-fidelity driving simulator using actor-recorded voice agents. Twenty-two female and nineteen male driver-licensed participants were recruited to drive simulated vehicles with voice agents and evaluated. The results demonstrated that compared with the dominant voice, the agent with a submissive voice significantly increased ER in both manual and automated driving. Furthermore, the submissive voice significantly increased trust in automated driving compared with the dominant agent. Cross and synergistic interaction effects exist between voice dominance and driving automation in SA and ER, respectively. This study revealed that both the content of the messages of the IVAs and their voice characteristics are essential for modulating the driver’s SA, ER, and trust in driving. It is expected that larger-scale future studies with simulation or on a real road would increase the validity of this study.     

Leg stiffness: Comparison between unilateral and bilateral hopping tasks

Leg stiffness is a predictor of athletic performance and injury and typically evaluated during bilateral hopping. The contribution of each limb to bilateral leg stiffness, however, is not well understood. This study investigated leg stiffness during unilateral and bilateral hopping to address the following research questions: (1) does the magnitude and variability of leg stiffness differ between dominant and non-dominant legs? (2) Does unilateral leg stiffness differ from bilateral leg stiffness? and (3) Is bilateral leg stiffness determined by unilateral leg stiffness? Thirty-two physically active males performed repeated hopping tests on a force platform for each of the three conditions: bilateral hopping, unilateral hopping on the dominant leg, and unilateral hopping on the non-dominant leg. Leg stiffness was estimated as the ratio of the peak vertical force and the maximum displacement using a simple 1-D mass-spring model. Neither the magnitude nor variability of leg stiffness differed between dominant and non-dominant limbs. Unilateral leg stiffness was 24% lower than bilateral stiffness and showed less variability between consecutive hops and subjects. Unilateral leg stiffness explained 76% of the variance in bilateral leg stiffness. We conclude that leg stiffness estimates during unilateral hopping are preferable for intervention studies because of their low variability.     

Speaking (Un‐)Truth to Power: Conspiracy Mentality as a Generalised Political Attitude

Conspiracy theories explain complex world events with reference to secret plots hatched by powerful groups. Belief in such theories is largely determined by a general propensity towards conspirational thinking. Such a conspiracy mentality can be understood as a generalised political attitude, distinct from established generalised political attitudes such as right‐wing authoritarianism (RWA) and social dominance orientation (SDO) (Study 1a, N = 497) that is temporally relatively stable (Study 1b and 1c, total N = 196). Three further studies (combined N = 854) show that in contrast to RWA and SDO, conspiracy mentality is related to prejudice against high‐power groups that are perceived as less likeable and more threatening than low‐power groups, whereas SDO and RWA are associated with an opposite reaction to perceptions of power. Study 5 (N = 1852) investigates the relationship of conspiracy mentality with political behavioural intentions in a specific catastrophic scenario (i.e. the damage to the Fukushima nuclear reactor after the 2011 tsunami in Japan) revealing a hitherto neglected role of conspiracy mentality in motivating social action aimed at changing the status quo.

Interest and Expertise Moderate the Relationship between Right‐Wing Attitudes,Ideological Self‐Placement and Voting

Previous research has suggested that the association between right‐wing authoritarianism (RWA) and social dominance orientation (SDO) is moderated by political interest and involvement. It is here hypothesized that interest also strengthens the association of authoritarianism with political self‐placement and that higher levels of interest in politics shape voting choices that are more strongly associated with authoritarianism. Authoritarianism was defined as a second‐order factor reflecting onto SDO and RWA in a structural equation modelling approach. In Study 1 (two samples, total N = 873), interest was found to moderate the impact of authoritarianism, as hypothesized. In Study 2 (N = 721), a higher order interaction involving interest and political expertise was detected. These results were obtained with different measures and in different electoral campaigns. The motivational and cognitive underpinnings of the moderating effects are discussed. Copyright © 2012 European Association of Personality Psychology.     

The Suppression and Justification of Prejudice as a Function of Political Orientation

Politically conservative (versus liberal) individuals generally report more prejudice towards various low‐status out‐groups. Three studies examined whether prejudice suppression factors—specifically, internal and external motivation to suppress (IMS and EMS, respectively) prejudice—can help explain the relationship between political orientation and prejudice. Study 1 showed that IMS and EMS partially mediated the relationship between political orientation and affective prejudice towards Arabs. Study 2 demonstrated that when justification [right‐wing authoritarianism (RWA) and social dominance orientation] and suppression (IMS and EMS) factors are simultaneously tested as mediators, only RWA partially mediated the relationship between political orientation and prejudice towards deviant (e.g. gay men) out‐groups, whereas RWA and IMS fully mediated the relationship between political orientation and prejudice towards derogated out‐groups (e.g. Blacks). Intriguingly, IMS rendered social dominance orientation effects non‐significant for derogated out‐groups. Study 3 showed that anticipating an out‐group interaction (with a Black or lesbian confederate) diminished the mediational contribution of IMS in the political orientation–prejudice relationship because of increased IMS among participants; yet the increases in IMS did not completely eliminate differences in prejudice as a function of political orientation. Ultimately, these three studies demonstrate that suppression (in addition to justification) factors do help explain the relationship between political orientation and prejudice.

Early Positive Information Impacts Final Evaluations: No Deliberation‐Without‐Attention Effect and a Test of a Dynamic Judgment Model

Evaluation judgments were affected by information order and not by subsequent unconscious versus conscious deliberation. In three experiments, we examined the influence of early positive information on final evaluations of four objects. Based on a task analysis, we predicted primacy effects in judgments in a sequential data acquisition task. Thinking periods following presentation were used to manipulate conscious or unconscious processing. In all three studies, we found no effects of thinking manipulations but instead found reliable order effects. We developed and tested an online judgment model on the basis of the belief updating model of Hogarth and Einhorn. The model accounted for large proportion of the individual level variability, and model comparison tests supported the presence of a primacy effect. Copyright © 2013 John Wiley & Sons, Ltd.     

Confirmatory Search and Asymmetric Dominance

Decision makers use confirmatory search strategies in judgment tasks. As a result of this, their attention towards task‐relevant cues is biased in favor of cues supporting available responses. Changing these responses can alter the cues used in the judgment task and, subsequently, alter beliefs. We use this mechanism to predict and explain the emergence of the asymmetric dominance effect in judgment. In four sets of experiments, we document systematic changes in belief, as dominated options are added to the response set. These effects emerge for a number of naturalistic judgment tasks and are mediated by the increased accessibility of decoy‐supporting cues. Finally, these effects can be eliminated when the decision maker's attention is drawn towards the cues supporting the non‐dominant response. Copyright © 2014 John Wiley & Sons, Ltd.     

Social dominance orientation predicts drive for muscularity among British men

The present study tested the hypothesis that men's drive for muscularity would be associated with their valuation of domination, power, status, and aggression over others. A community sample of 359 men from London, UK, completed measures of drive for muscularity, social dominance orientation, right-wing authoritarianism, trait aggression, and need for power, as well as their demographic details. Bivariate correlations showed that greater drive for muscularity was significantly correlated with most of the measures and their subscales. However, in a multiple regression analysis, the only significant predictor of drive for muscularity was support for group-based dominance hierarchies (Adj. R² = .17). These results suggest that men's drive for muscularity is associated with a socio-political ideology that favours social dominance.     

Language dominance in translation priming: Evidence from balanced and unbalanced Chinese–English bilinguals

It is well established in the masked translation priming literature that the priming effect is sensitive to language direction with noncognates—namely, the priming effect is consistently observed from first language (L1) to second language (L2), but not always from L2 to L1. Several recent reports demonstrated both L1–L2 and L2–L1 priming and attributed the restoration of L2–L1 priming to high proficiency in L2. Here, the current study tested two groups of highly proficient Chinese–English bilinguals, with one group more dominant in English and the other more balanced in both languages. The L2–L1 priming effect was only observed with the balanced bilinguals, but not the English-dominant ones. Based on these results, I argue that the language proficiency account is not sufficient to explain the priming asymmetry and that the relative bilingual balance is a more accurate account. Theoretically, the cross-language balance is determined by the representational difference between L1 and L2 at the semantic level. I discuss the results in relation to various bilingual models, in particular, the sense model and the distributional representational model (DRM), which capture the semantic representations of bilinguals.
