理性行动-社会认同整合性集体行动模型

为探究理性行动理论和社会认同理论两大社会心理学宏论对于个体集体行动参与倾向的共同解释力,以“中日撞船事件”为考察蓝本向天津市431名大学生被试进行调查研究,结果发现：效能和社会规范作为态度和行动倾向的中介变量,在不同情境下对行动倾向的作用不同,符合理性行动原则;内部动机作为态度和效能、社会规范之间的中介变量,并受到学校认同和国家认同的直接或间接影响,支持了社会认同理论对遵从规范行为的解释;回归分析验证了不同水平认同对行动倾向作用程度的差异,整合模型则揭示了其具体的作用路径和影响机制.结论：理性行动理论与社会认同理论可彼此互补成为集体行动参与的整合性解释框架.     

社会交流中人际神经同步的认知机制

近年来,许多研究者开始关注社会交流中的人际神经同步机制,并将人际神经同步作为研究社会交流的一个神经指标,这对于揭示社会交流的本质和规律具有重要意义。本文从心理理论和镜像神经系统的角度,分析社会交流中神经同步的认知机制及其影响因素。未来的研究应关注这两套机制是否因交流目的、对象、形式或内容的不同,而在不同的脑区表现出神经同步,进而引发了不同认知机制的争议;以及这两套机制各自或协同工作适用的情景和任务。     

The effect of variations of emotional expressions on mnemonic discrimination and traditional recognition memory

Face recognition occurs when a face is recognised despite changes between learning and test exposures. Yet there has been relatively little research on how variations in emotional expressions influence people’s ability to recognise these changes. We evaluated the ability to discriminate old and similar expressions of emotions (i.e. mnemonic discrimination) of the same face, as well as the discrimination ability between old and dissimilar (new) expressions of the same face, reflecting traditional discrimination. An emotional mnemonic discrimination task with morphed faces that were similar but not identical to the original face was used. Results showed greater mnemonic discrimination for learned neutral expressions that at test became slightly more fearful rather than happy. For traditional discrimination, there was greater accuracy for learned happy faces becoming fearful, rather than those changing from fearful-to-happy. These findings indicate that emotional expressions may have asymmetrical influences on mnemonic and traditional discrimination of the same face.     

Use of Level 1 and 2 driving automation on horizontal curves on interstates and freeways

Little is known about how the actual use of Level 1 and 2 driving automation systems may be affected by geometric road characteristics in naturalistic driving environments. This study examined the use of these systems on horizontal curves on interstates and freeways. It used travel data collected in a field operational test conducted with two 2016 Land Rover Range Rover Evoque vehicles equipped with adaptive cruise control (ACC) and two 2017 Volvo S90 vehicles equipped with ACC and Pilot Assist (PA). Logistic regression models estimated changes in the likelihood of ACC use associated with horizontal curvature in the Evoque vehicles, and of PA and ACC use in the S90 vehicles, while accounting for traffic conditions. Drivers were less likely to drive with ACC or PA on as horizontal curves became sharper. In the Evoque vehicles, the likelihood of using ACC was 71.6% lower on the sharpest category of horizontal curves (those with a degree of curvature>2.5 degrees per 100 feet of arc or a radius smaller than 2,292 feet), compared with straight road segments or the flattest horizontal curve category (those with a degree of curvature <= 1.5 degrees per 100 feet of arc or a radius no <3,820 feet). In the S90 vehicles, the likelihood of using PA and ACC declined 74.6 and 66.3%, respectively, on the sharpest curves. Many driving automation systems face challenges on horizontal curves, even within their operational design domain. Future implementations that improve functionality may enhance driver experience and boost drivers’ confidence in these systems, which should increase their use and maximize the safety benefits these systems might offer.

Deactivation in the sensorimotor area during observation of a human agent performing robotic actions

It is well established that several motor areas, called the mirror-neuron system (MNS), are activated when an individual observes other’s actions. However, whether the MNS responds similarly to robotic actions compared with human actions is still controversial. The present study investigated whether and how the motor area activity is influenced by appearance (human vs. robot) and/or kinematics (human vs. robot) of the observed action using near-infrared spectroscopy. The results showed that there was a strong interaction between these factors, revealing strong deactivations in sensorimotor areas when the subject saw a human agent performing robotic actions, which was significantly different from responses when observing the human agent acting in a human way and the robot agent performing robotic actions. These results indicate that MNS activity is sensitive to congruency between the appearance and kinematics of the agent, especially when the agent has a human appearance. We discuss the experience-dependent characteristics of MNS sensitivity to observed actions.     

Incongruent imagery interferes with action initiation

It has been suggested that representing an action through observation and imagery share neural processes with action execution. In support of this view, motor-priming research has shown that observing an action can influence action initiation. However, there is little motor-priming research showing that imagining an action can modulate action initiation. The current study examined whether action imagery could prime subsequent execution of a reach and grasp action. Across two motion analysis tracking experiments, 40 participants grasped an object following congruent or incongruent action imagery. In Experiment 1, movement initiation was faster following congruent compared to incongruent imagery, demonstrating that imagery can prime the initiation of grasping. In Experiment 2, incongruent imagery resulted in slower movement initiation compared to a no-imagery control. These data show that imagining a different action to that which is performed can interfere with action production. We propose that the most likely neural correlates of this interference effect are brain regions that code imagined and executed actions. Further, we outline a plausible mechanistic account of how priming in these brain regions through imagery could play a role in action cognition.     

The Ideological Legitimation of the Status Quo: Longitudinal Tests of a Social Dominance Model

Four studies examined whether members of the dominant group (New Zealand Europeans) who were high in Social Dominance Orientation (SDO) employed ideologies of equality-as-meritocracy to legitimate opposition toward policy-based resource allocations that favor disadvantaged groups. We tested this model, derived from Social Dominance Theory, using cross-sectional (Study 1; N =  338) and longitudinal data (Studies 2–4) collected in New Zealand. As predicted, SDO (but not Right-Wing Authoritarianism) exerted a cross-lagged effect on Equality Positioning and not vice-versa (Study 2; 1 year, N =  81); Equality Positioning exerted a cross-lagged effect on attitudes toward resource-specific social policies but not vice-versa (Study 3; 4 months, N =  132); and the cross-lagged effect of SDO on attitudes toward resource-specific policy was mediated longitudinally by Equality Positioning (Study 4; 1 year, N =  47). These findings indicate that the ideological positioning of equality is (at least partially) driven by individual differences in the motivation for group-based social dominance, and this in turn determines support for social and political policies that govern the group-based allocation of resources within society and thus systemic inequality.     

Inferring the preferences of others from spontaneous, low-emotional facial expressions

The present study investigates whether people can infer the preferences of others from spontaneous facial expressions alone. We utilize a paradigm that unobtrusively records people's natural facial reactions to relatively mundane stimuli while they simultaneously report which ones they find more appealing. Videos were then presented to perceivers who attempted to infer the choices of the target individuals—thereby linking perceiver inferences to objective outcomes. Perceivers demonstrated above-chance ability to infer target preferences across four different stimulus categories: people (attractiveness), cartoons (humor), paintings (decorative appeal), and animals (cuteness). While perceivers' subjective ratings of expressivity varied somewhat between targets, these ratings did not predict the relative “readability” of the targets. The findings suggest that noncommunicative, natural facial behavior by itself suffices for certain types interpersonal prediction, even in low-emotional contexts.
