Effect of external HMI for automated vehicles (AVs) on drivers’ ability to infer the AV motion intention: A field experiment

A field experiment was conducted aiming to shed light on how drivers negotiate an ambiguous traffic situation when encountering an autonomous vehicle (AV) in the presence of a yielding intention signal (AV with eHMI) or not (AV without eHMI). A traffic conflict scenario was created with two opposing vehicles instructed to perform a left turn at a four-way junction, at the same point in time. Forty participants were assigned to two groups encountering either an AV with eHMI or an AV without eHMI. To check for equivalence across the two groups, both groups also encountered a conventional vehicle (CV). Results showed that the two groups performed similarly during encounters with a CV. During encounters with AV, however, participants provided with the eHMI maintained higher speed before the AV and finished their maneuver quicker than when they were not provided with eHMI. Additionally participants provided with eHMI rated higher their ability to infer the AV intention before coming to a full-stop than those provided without eHMI. The above findings indicate that the presence of eHMI on AV can accelerate drivers’ inferences about yielding intention of an AV, and have the potential to optimize AV-driver interaction in ambiguous traffic situations.     

Intuitive Dualism and Afterlife Beliefs: A Cross-Cultural Study

It is widely held that intuitive dualism—an implicit default mode of thought that takes minds to be separable from bodies and capable of independent existence—is a human universal. Among the findings taken to support universal intuitive dualism is a pattern of evidence in which “psychological” traits (knowledge, desires) are judged more likely to continue after death than bodily or “biological” traits (perceptual, physiological, and bodily states). Here, we present cross-cultural evidence from six study populations, including non-Western societies with diverse belief systems, that shows that while this pattern exists, the overall pattern of responses nonetheless does not support intuitive dualism in afterlife beliefs. Most responses of most participants across all cultures tested were not dualist. While our sample is in no way intended to capture the full range of human societies and afterlife beliefs, it captures a far broader range of cultures than in any prior study, and thus puts the case for afterlife beliefs as evidence for universal intuitive dualism to a strong test. Based on these findings, we suggest that while dualist thinking is a possible mode of thought enabled by evolved human psychology, such thinking does not constitute a default mode of thought. Rather, our data support what we will call intuitive materialism—the view that the underlying intuitive systems for reasoning about minds and death produce as a default judgment that mental states cease to exist with bodily death.     

Perception of communal motives in couples: Accuracy,bias, and their associations with relationship length

Can romantic partners accurately perceive each other’s communal motives, or are these perceptions biased by their own motivational hopes and fears? This study used data from N = 1,905 partnered participants to examine the extent to which partner perceptions of communal motives correspond to targets’ (accuracy) and perceivers’ (motivational bias) explicit and implicit communal motives. Our results indicate that explicit communal motives and implicit communal approach motives can be (a) accurately inferred and (b) positively bias communal motive perception. Furthermore, there was no evidence for moderation of either accuracy or motivational bias by relationship length. These findings point to the early visibility of both implicit and explicit motives in couples, as well as their persistent biasing effects on partner perception.     

知觉模糊度影响学习的延迟效应

基于迁移适当加工理论,采用连续识别任务范式,通过操纵字词和图片的模糊度来考察知觉模糊非流畅的延迟效应。结果发现：（1）模糊不流畅的材料学习判断值更低;（2） 知觉模糊程度对即时的再认成绩没有影响,但在延迟再认测试中流畅性较低的模糊材料成绩更好。该结果表明实验操纵方式所引发的编码过程和记忆测试所需的检索过程性质上相匹配,而且延迟测试时,知觉非流畅可以促进学习,说明该效应存在边界。     

Not Simply in the Eye of the Beholder: Authenticity as a Product of Candidate Preference and Unfettered Speech

Authenticity has emerged over recent decades as a prominent theme in both the press and in political research—and peaked in the 2016 presidential contest that pitted Donald Trump against Hillary Clinton, Bernie Sanders, Marco Rubio, and Ted Cruz. In this context, we attempted to answer the question: How do voters judge a presidential candidate's authenticity? Here we use motivated reasoning and correspondent inference theory as theoretical frameworks to examine how partisan preference combines with perceptions of unfettered speech and strategic impression management to influence voter judgments of a candidate's authenticity. An online survey of 525 respondents demonstrated that individuals' partisan preferences influenced both judgments of a candidate's authenticity and their perceptions of behaviors signifying authenticity (use of unfettered speech versus strategic impression management). These behavioral signals partially mediated the relation between candidate preferences and authenticity judgments. Moreover, voters, given their partisan preferences, differentially weighted candidates' use of unfettered speech and strategic impression management tactics in their judgments of authenticity. Finally, unfiltered/politically incorrect speech was found to have both positive and negative effects on authenticity judgments. Findings further elucidate the nature of authenticity as perceived in others and identify intermediary variables and boundary conditions that influence those perceptions.     

Monitoring of learning for emotional faces: how do fine-grained categories of emotion influence participants’ judgments of learning and beliefs about memory?

Researchers have evaluated how broad categories of emotion (i.e. positive and negative) influence judgments of learning (JOLs) relative to neutral items. Specifically, JOLs are typically higher for emotional relative to neutral items. The novel goal of the present research was to evaluate JOLs for fine-grained categories of emotion. Participants studied faces with afraid, angry, sad, or neutral expressions (Experiment 1) and with afraid, angry, or sad expressions (Experiment 2). Participants identified the expressed emotion, made a JOL for each, and completed a recognition test. JOLs were higher for the emotional relative to neutral expressions. However, JOLs were insensitive to the categories of negative emotion. Using a survey design in Experiment 3, participants demonstrated idiosyncratic beliefs about emotion. Some people believed the fine-grained emotions were equally memorable, whereas others believed a specific emotion (e.g. anger) was most memorable. Thus, beliefs about emotion are nuanced, which has important implications for JOL theory.     

Social and medical influences on attributions and evaluations of chronic pain

Abstract

Previous research suggests that judgments of pain are subject to social influences, including characteristics of the person in pain, the judge, and the social context in which the judgment occurs. In this experiment, eight vignettes describing a person with chronic low back pain were varied as a function of patient ethnicity (Caucasian vs African-American), litigation status (litigant vs non-litigant), and medical evidence (strong vs weak). Participants (N= 116) read vignettes, made attributions of causality for the person's pain and disability, and evaluated the severity of the pain syndrome. Pain and disability were perceived as more legitimate when the person in pain was a non-litigant and when medical evidence was strong. Evaluations of syndrome severity were more extreme when evidence was strong. A three-way interaction indicated that judgments may have been influenced by ethnic stereotypes. These findings substantiate the influence of social variables in judgments of persons with pain.     

Voice pitch preferences of adolescents: Do changes across time indicate a shift towards potentially adaptive adult-like preferences?

An evolutionary approach to attractiveness judgments emphasises that many human trait preferences exist in order to assist adaptive mate choice. Here we test an adaptive development hypothesis, whereby voice pitch preferences indicating potential mate quality might arise or strengthen significantly during adolescence (when mate choice becomes adaptive). We used a longitudinal study of 250 adolescents to investigate changes in preference for voice pitch, a proposed marker of mate quality. We found significantly stronger preferences for lower-pitched opposite-sex voices in the older age group compared with the younger age group (using different sets of age-matched stimuli), and marginally increased preferences for lower-pitched opposite-sex voices comparing within-participant preferences for the same set of stimuli over the course of 1 year. We also found stability in individual differences in preferences across adolescence: controlling for age, the raters who had stronger preferences than their peers for lower-pitched voices when first tested, retained stronger preferences for lower-pitched voices relative to their peers about 1 year later. Adolescence provides a useful arena for evaluating adaptive hypotheses and testing the cues that might give rise to adaptive behaviour.     

Explicit and implicit emotion regulation: A dual-process framework

It is widely acknowledged that emotions can be regulated in an astonishing variety of ways. Most research to date has focused on explicit (effortful) forms of emotion regulation. However, there is growing research interest in implicit (automatic) forms of emotion regulation. To organise emerging findings, we present a dual-process framework that integrates explicit and implicit forms of emotion regulation, and argue that both forms of regulation are necessary for well-being. In the first section of this review, we provide a broad overview of the construct of emotion regulation, with an emphasis on explicit and implicit processes. In the second section, we focus on explicit emotion regulation, considering both neural mechanisms that are associated with these processes and their experiential and physiological consequences. In the third section, we turn to several forms of implicit emotion regulation, and integrate the burgeoning literature in this area. We conclude by outlining open questions and areas for future research.
