Three experiments examined the role of response criteria in a masked semantic priming paradigm using an exclusion task. Experiment 1 used on-line prime-report (“report the prime if you saw it”) and exclusion instructions in which participants were told to avoid completing a word stem (e.g. mo—) with a word related to a prime (e.g. cash) flashed for 0, 38 or 212 ms. Semantic priming (i.e. exclusion failure) was significant in the items analysis, but was moderated by peoples’ ability to report the prime in the participant analysis. Prime-report thresholds in Experiment 2 were made more liberal by instructing participants to guess on every trial. Prime-report increased from Experiment 1 as exclusion failures were eliminated. Experiment 3 clarified the relationship between awareness and prime identification using an on-line measure of confidence and different liberal prime report instructions. The current findings suggest that the ability to act upon (via exclusion performance) and report information in a masked prime is determined by a variable response criterion, which can be manipulated as an independent variable. 相似文献

Causal attributions for events are shaped by information about causal mechanisms that contribute to the events. In the case of damage from earthquakes, these mechanisms include the design of buildings. Three studies presented scenarios drawn from actual reports of recent earthquakes (Kobe, Japan and Northridge, California, USA), including statements by engineers about the quality of the design of damaged and undamaged buildings. Studies examined whether this design information affected attributions for earthquake damage. Participants attributed damage to building design more strongly and rated damage more preventable when scenarios referred to the poor building design of damaged buildings than when scenarios gave no design information. Information about the excellent design of undamaged buildings had less consistent effects. This effect was most consistent with scenarios about the design of damaged buildings. These findings show that mechanism (design) information does influence judgments about damage in earthquakes and, by implication, other hazards. 相似文献

社会信息加工中的相关性维度 总被引:1,自引:1,他引:0
在以往的社会信息加工研究中,多数情况只对刺激作积极、消极的效价区分,这往往导致实验结论中出现困惑和矛盾之处。Peeters提出了另一个区分刺激的维度:相关性(他相关、主相关)。Wentura等人把这一区分引入实验设计后,不但合理解释了以往研究中的问题和疑点,而且获得了新的发现。因此,相关性区分的引入对于此类研究有着重要意义,并对印象形成、刻板印象和群体等其他实验社会心理研究都有一定启发。 相似文献

顿悟:是进程监控还是表征转换 总被引:1,自引:0,他引:1
当前解释顿悟问题解决机制的理论主要有表征转换理论和进程监控理论。进程监控理论主要解释了顿悟问题为什么困难,但事实上它并没有说明顿悟问题为什么会解决,只回答了在什么情况下被试才会寻求其他的方法,而且它把顿悟问题解决的一般过程看成是同常规问题解决方法相同的过程。而表征转换理论主要解释了顿悟是如何获得的——顿悟的获得是由于问题解决者对问题的表征实现了正确的转变,但它并没有解释表征什么时候、怎么样才能转变?顿悟问题的解决经历了三个认知加工阶段,顿悟问题的解决需要在消除定势情况下激活正确的启发信息(线索),并验证了顿悟问题的原型激活和关键启发信息理论假说。 相似文献

我国无统一的多发性硬化(MS)诊断标准,MS的诊断依据Poser标准和McDonald标准。McDonald标准是建立在Poser标准基础上,但更注意利用包括MRI在内的相关实验室检查来证明多发性硬化在时间和空间上的多发性,有利于MS的早期诊断及治疗。对于没有MRI仪器的地方或不能承担MRI检查费用者,可用Poser标准进行诊断,但要注意行视觉诱发电位检查及脑脊液寡克隆IgG区带测定。 相似文献

ObjectivesCricket batting is performed under demanding constraints, which requires rapid and accurate decision making for successful achievement of the skill goal. To understand how batsmen negotiate these constraints, the capability of highly skilled and low skilled cricket batsmen to utilise visual information prior to and during sections of ball flight to strike balls delivered by fast bowlers was examined.MethodSix highly skilled and six low skilled batsmen faced different types of balls delivered by three fast bowlers. Batsmen wore vision occlusion spectacles and were required to strike delivered balls, while their vision of the bowler's delivery action and ball flight was selectively occluded. Three vision conditions were randomly designed that included temporal occlusion at: (i) a point prior to ball release (providing only advance information), (ii) a point prior to ball bounce (providing advance and ball flight information) and (iii) no occlusion (where all advance, ball flight and bounce information were visible). Foot movements made forward or backward were assessed as a measure of ball length judgement, while the quality of bat–ball contact was assessed as a measure of interception.ResultsResults demonstrated the superior capability of highly skilled batsmen to utilise information prior to ball release to judge short ball length. Expert batsmen were better able to utilise ball flight information prior to and post-bounce to attain a superior number of bat–ball contacts.ConclusionsFindings demonstrate that the mechanism of experts to deal with task constraints when attempting to intercept a delivered ball is their capability to pick-up visual information to judge ball landing position. 相似文献

运用视知觉研究中经典的事件切割程序,探讨记叙文中时间信息的事件边界效应.结果发现记叙文中的时间信息会被读者外显地知觉为事件边界,并且,跨度长的时间信息比跨度短的时间信息更易于被知觉为事件边界.这和视知觉研究中的发现是一致的.研究在一定程度上支持了记叙文理解过程中情境模型建构的过程依赖类似于事件知觉中所发现的切割过程的观点,为知觉研究和认知研究领域提供了可供沟通的实证支持. 相似文献
