视觉显示技术的新视角：交互显示

交互显示技术是近年人机界面显示技术中形成的一种新型显示技术。这种技术能根据用户的即时输入或操作特点改变初始界面中的显示内容或方式。交互显示技术可分为简单交互显示技术，如鱼眼技术及其应用，和智能交互显示技术，如速率耦合平滑技术，目标气泡技术等。目前的交互显示技术具有动态性、即时性和智能性等特点，但仍存在如交互方式单一，智能性不高等问题，未来研究需强调显示内容变化、交互形式的多样性及其高级智能交互技术等方面的研究。

不同提示方式的多元图形视觉显示工效学研究

以图形作为实验材料,感觉辨别力和元素权重为实验指标,高可靠性图形的提示方式(没有提示、颜色、亮度、闪烁)为自变量．本文研究了不同提示方式对被试决策绩效的影响,确定图形显示时较优的提示方式。研究结果表明提示能够显著提高被试的决策绩效,在颜色、亮度、闪烁三种提示方式中,较优的提示方式是闪烁。     

Performance Benefits of Spatially Distributed Versus Stacked Information on Integration Tasks

Understanding the best way to present information has been an issue of interest to many researchers. Regardless of the content of the information, purely physical elements such as spatial organization may also influence performance. Across two studies with 111 undergraduates (78 in Study 1 and 33 in Study 2), we compared spatially distributed (i.e. when information sources are presented side‐by‐side) against stacked displays (i.e. when information sources are sitting on top of one another with only the top source fully visible). A distributed display time advantage was consistently observed. As potential explanations, a memory strategy selection hypothesis was examined along with other procedural alternative explanations.

中文阅读中的认知滞后效应

该研究应用EyelinkⅡ眼动仪,采用眼动随动显示技术操纵注视点左侧文本被掩蔽词汇的范围,考察中文阅读过程中词汇加工的认知滞后效应。结果发现:掩蔽词n以左的文本可严重影响被试的总阅读时间;掩蔽词n-1以左文本则不影响被试的总阅读时间。结果表明,相对于注视位置,中文阅读的认知过程存在明显的滞后效应。     

不同风险态度大学生职业决策的线索偏好及信息搜索特点

探讨不同风险态度的大学生在职业决策中的线索偏好及信息搜索特点。以大学生为被试,以Weber的风险态度问卷为工具,筛选出风险寻求大学生26名,风险规避大学生23名,采用信息板技术进行模拟职业决策研究。结果发现：（1）风险寻求和风险规避大学生在职业决策中点击次数最多的职业属性均依次是工资、发展空间和兴趣;（2）在信息板的点击次数上,风险寻求被试比风险规避被试更多;在搜索模式上,风险寻求组被试和风险规避组的得分均为正值,但风险寻求组被试的得分显著高于风险规避组。因此,大学生职业决策中偏好的线索主要是工资、发展空间和兴趣;风险寻求者的信息搜索模式与风险规避者不同,风险寻求者更倾向于以选项为基础的搜索模式。     

员工正念对配偶家庭满意度和工作投入的影响

文章基于资源保存理论, 采用体验抽样法收集了一家商业银行114名员工及其配偶的数据。结果表明, 在个体内层面, 员工正念通过员工情感联结策略的中介作用影响其配偶家庭满意度及第二天早上工作投入; 在个体间层面的配偶家庭负面情感表达调节了员工正念与员工情感联结策略的关系及员工情感联结策略的中介作用, 即配偶家庭负面情感表达水平越高, 员工正念对员工情感联结策略的影响及员工情感联结策略的中介作用相对更弱。     

On-court position and handedness in visual anticipation of stroke direction in tennis

ObjectivesIn racket sports, players integrate information picked up from their opponent's kinematics and contextual cues like on-court position into shot outcome anticipation. In view of suggested difficulties with anticipating left-handed opponents' action intentions, here we examined whether an opponent's handedness interacts with position-dependency in visual anticipation.Design and methodFollowing a 2 (Group) x 2 (Handedness) x 2 (Position) x 3 (Temporal Occlusion) factorial design, 20 tennis players and 20 non-players predicted directional outcome of temporally manipulated point-light animations of identical left- and right-handed forehand groundstrokes performed near vs. far from the court's midline.ResultsTennis players' response selection was mostly affected by an opponent's on-court position, particularly at an early stage of a hitting movement. Opponents' handedness affected response selection similarly in both groups (i.e., bias towards down-the-line predictions against left-handed strokes occluded at racket-ball-contact), but it did not interact with on-court position.ConclusionsFindings highlight that on-court position, and opponents' handedness to some extent as well, appears relevant for skilled visual anticipation in tennis.     

不同性质语篇背景信息的激活与抑制

运用窗口阅读及再认探测技术,探讨即时与延迟状态下合适与不合适背景信息的激活模式。被试阅读含有精细阐述错误信息的实验材料及不含错误信息的参照材料,并对合适或不合适(参照条件下为无关)的探测词进行再认反应。结果发现,合适与不合适信息激活关系随时程延长发生的逆转是由于合适信息激活水平得到提升、不合适信息受到抑制所导致。但即使在延迟状态下,不合适先行词的激活水平也并没有降到与一个无关信息等同的程度,表明受精细阐述的错误信息即使在经过更正之后,其在语篇表征中仍有着比较重要的地位。     

Conventional displays: Evidence for socially mediated costs of threat displays in a lizard

Threat displays are used to settle the vast majority of contests between green anoles (Anolis carolinensis). While these displays have been the subject of a number of studies, very little is understood about the information they convey. Theoretical models divide displays into several types of signals, based on the mechanism that stabilizes their use: 1) performance signals, 2) handicapping signals, or 3) conventional displays. The existence of performance displays has excellent empirical support, as do models of their use. Handicapped signalling models, especially those relating to mate‐choice, have been highly influential, though little evidence suggests that threat displays are, in fact, handicapping. Most threat displays appear to be conventional, but little empirical work documents conventional signalling systems. This study investigated the use of headbob, pushup, and lateral compression displays, and concluded that headbob cadence, a discrete signal with three alternative rhythms, is a conventional display indicating impending escalation. Pushups and lateral compression displays appear not to be handicaps, since neither indicates impending escalation, and they do not correlate with fighting ability or condition. Aggr.
