Effects of different non-driving-related-task display modes on drivers’ eye-movement patterns during take-over in an automated vehicle

Highly automated vehicles relieve drivers from driving tasks, allowing them to engage in non-driving-related-tasks (NDRTs). However, drivers are required to take over control in certain circumstances due to the limitations of highly automated vehicles. This study focused on drivers’ eye-movement patterns during take-overs when an NDRT (watching videos) was presented via a head-up-display (HUD) and a mobile device display (MDD), compared to no NDRT as the baseline. The experiment was conducted in a high-fidelity driving simulator with real-world driving videos scenarios. Forty-six participants took part in the experiment by completing three drives in three counterbalanced conditions (HUD, MDD and baseline). A take-over-request was issued towards the end of automated driving requesting drivers to stop the NDRT and take over control. Eye-movement data including pupil diameter, blinks, glance duration and number of AOI (Area of Interest) were collected and analysed. The results show that during automated driving, drivers were more engaged in the MDD NDRT with smaller pupil diameter and shorter glance duration on the front scenario compared to the HUD and baseline modes. The number of AOI was reduced during automated driving in both MDD and HUD modes. The take-over-request redirected drivers’ visual attention back to the driving task from NDRT by increasing drivers’ pupil diameter, glance duration and number of AOI. However, the effect of MDD NDRT on pupil diameter and glance duration continued even after the take-over-request when the NDRT was terminated. The study demonstrated HUD is a better display to help maintain drivers’ attention on the road.     

传统媒体上强势品牌广告竞争溢出效应的作用机制及分布规律

由于产品之间存在相互关联性, 一个企业的广告不仅会对本企业产品的市场需求产生促进作用, 而且对其它企业产品的市场需求也会产生一定影响, 这种影响被称为广告的溢出效应。以往研究发现, 强势品牌广告竞争对弱势品牌具有溢出效应, 但该研究仅验证了溢出效应存在, 并未对其作用机制进行深入挖掘。通过实验方法探讨强势品牌广告竞争对弱势品牌的溢出效应的作用机制及边界条件是当务之急, 实验一探讨强势品牌广告竞争对弱势品牌溢出效应的作用机制, 主要包括探讨中介变量和调节变量两个方面的问题。中介变量包括消费者对强势品牌的涉入度、感知产品质量、行业市场份额变化三个变量, 调节变量包括消费者广告态度、消费者任务导向、产品生命周期、产品同质性四个变量。实验二探讨强势品牌广告竞争对弱势品牌的溢出效应的整体分布规律, 包括产品成长期和成熟期两个时期的溢出效应分布规律。研究将揭示强势品牌广告竞争的作用机制和整体分布规律, 有利于丰富溢出效应理论和广告效果理论。     

Is the street-crossing behavior with a head-mounted display different from that behavior in a CAVE? A study among young adults and children

The use of virtual reality (VR) has become increasingly popular in the field of traffic psychology, where realistic traffic situations can be simulated and pedestrians‘ actual crossing behavior can be studied. There are two main kinds of pedestrian simulators: one uses a technology based on rear-projection screens (Cave Automatic Virtual Environment, or CAVE); the other uses a head-mounted display (HMD). Despite their extensive use, it is yet to determine whether they are equally suitable for studying street crossing. The present study was aimed at comparing street-crossing behavior and subjective evaluations in an HMD-based (HTC vive pro) pedestrian simulator and a CAVE-like pedestrian simulator, among young adults and 12-year-old children. Thirty young adults and twenty-six children performed 36 street-crossing trials (combining different speeds, traffic conditions, and gap sizes) on each of the two simulators. The results indicated that, compared to the CAVE-condition participants, HMD-condition participants accepted more crossing trials (hence, shorter gaps), initiated their crossings sooner, crossed at a slower speed, had shorter safety margins, and caused more collisions. The main difference between the two devices was in crossing initiation, which occurred markedly earlier (1.72 s) with the HMD than in the CAVE: the perception–action coupling was less finely tuned in the CAVE, probably because visual information in front of the pedestrian was missing due the absence of ground projection and 3D rendering. A significant effect of vehicle-approach speed was observed for both devices, with more unsafe behaviors at 60 km/h than at 40 km/h. Children displayed riskier crossing behavior than young adults did, with more accepted crossings, slower crossing speeds, shorter safety margins, and higher collision rates, especially in the HMD. Compared to the CAVE, the HMD received higher ratings for level of presence and a preference for VR, but also higher simulator-sickness scores. No adverse effects of exposure to virtual reality was found on stereoacuity or postural balance. The suitability of using CAVE and HMD simulators is discussed, especially for studying child pedestrians.     

汉语双字词句知觉广度的眼动研究

阅读知觉广度通常指阅读者在阅读文本过程中每次注视能获取有用视觉信息的范围。既往的汉语知觉广度的研究一般把单字作为基本的知觉呈现单元,但在某些呈现条件下,此类呈现方式会导致阅读过程中的语义加工的完整性被破坏。本研究采用眼动追踪技术,使用移动窗口范式和中央凹掩蔽范式,使用双字词句作为阅读材料,双字词作为基本的知觉呈现单元,探讨在保证知觉呈现单元语义完整性的基础上大学生的汉语阅读知觉广度。实验一采用移动窗口范式,结果发现,知觉广度范围为注视词左侧1个双字词及右侧1-2个双字词的空间。实验二采用中央凹掩蔽范式,结果验证了实验一的研究结果。该结果表明,在汉语阅读过程中,以双字词为基本的视觉呈现单元,较既往研究中单字为基本呈现单元的情况,更好地保证了阅读中语义的完整性,从而获得了更大的知觉范围。该结果建立于视觉呈现单元的语义完整性的基础上,是对现有的汉语阅读知觉广度理论的完善和扩展。     

Local and global reference frames for environmental spaces

Two experiments examined how locations in environmental spaces, which cannot be overseen from one location, are represented in memory: by global reference frames, multiple local reference frames, or orientation-free representations. After learning an immersive virtual environment by repeatedly walking a closed multisegment route, participants pointed to seven previously learned targets from different locations. Contrary to many conceptions of survey knowledge, local reference frames played an important role: Participants performed better when their body or pointing targets were aligned with the local reference frame (corridor). Moreover, most participants turned their head to align it with local reference frames. However, indications for global reference frames were also found: Participants performed better when their body or current corridor was parallel/orthogonal to a global reference frame instead of oblique. Participants showing this pattern performed comparatively better. We conclude that survey tasks can be solved based on interconnected local reference frames. Participants who pointed more accurately or quickly additionally used global reference frames.     

通货膨胀、通货紧缩和产品类型对货币幻觉的影响

货币幻觉是指经济交易活动中,人们因倾向于以货币的名义价值而非实际价值思考从而对其消费和投资行为造成影响的一种认知偏差。本研究探讨了在通货膨胀和通货紧缩下以及产品类型对货币幻觉程度的影响。研究发现,在通货膨胀或通货紧缩下,大部分被试判断经济状况时不受货币名义价值的影响,而判断快乐程度和离职意向时受到货币名义价值的影响;在相同的涨价幅度下被试对日常消费品和昂贵消费品涨价幅度的判断差异显著,昂贵消费品引起人们更高程度的货币幻觉。     

The effect of goal activation on the evaluation of hybrid products1

A hybrid product (i.e. a multifinal means) is connected with goals relevant to the key functionalities best served by the product categories constituting the product. Given that single‐ or multiple‐category inference for a hybrid product can be elicited in individuals, we propose that single‐ (vs. multiple‐) category inference can lead to a relatively higher preference for the hybrid product if only one of the key focal goals that the hybrid product can satisfy is activated. We also explore whether the evaluation of a hybrid product in single‐category inference will reflect valuation and/or devaluation effects if only one of multiple key focal goals attached to the hybrid product is active.     

The Relation of Personal Epistemology to Parenting Style and Goal Orientation in College Mothers

This study sought to establish the relevance of mothers’ epistemic beliefs to their parenting style and preferred academic goals for their child. College mothers (N = 163) from primarily working class families completed a variety of self-report measures including a modified version of Schommer’s [(1990). Journal of Educational Psychology, 82, 498–504] Epistemological Beliefs Questionnaire, the Parental Attitudes Questionnaire-Revised [Reitman, Rhode, Hupp, & Altobello (2002). Journal of Psychopathology and Behavioral Assessment, 24(2), 119–127], and several goal orientation scales. Results indicated that a view of learning as effortful and under the learner’s control and a view of knowledge as actively constructed were associated with an authoritative parenting style and with a preference for their child to focus on learning, improvement, and effort in approaching academic tasks. By contrast, a view of learning as quick, straightforward, relatively passive and as based in innate constraints and a view of knowledge as consisting of discreet, unambiguous facts were associated with authoritarian and permissive styles and the adoption of performance goals for one’s child. Portions of this study were presented at the annual meeting of the Society for Research in Child Development in Atlanta, April, 2005.
