Two components in IOR: evidence for response bias and perceptual processing delays using the SAT methodology

Inhibition of return (IOR) occurs when reaction times (RTs) are slowed to respond to a target that appears at a previously attended location. We used the speed-accuracy trade-off (SAT) procedure to obtain conjoint measures of IOR on sensitivity and processing speed by presenting targets at cued and uncued locations. The results showed that IOR is associated with both delays in processing speed and shifts in response criterion. When the target was briefly presented, the results supported a criterion shift account of IOR. However, when the target was presented until response, the evidence indicated that, in addition to a response bias effect, there was an increase in the minimal time required for information about the target to accumulate above chance level. A hybrid account of IOR is suggested that describes effects on both response bias and perceptual processing.     

Attentional spreading in object-based attention: The roles of target–object integration and target presentation time

What is the best account to explain the object-based attentional benefit—that is, the spread of attention within an attended object or prioritization of search across possible target locations within an attended object? Using a task in which the location of the target was known with certainty, in the present study we systematically manipulated the type (letters or bites) and the presentation time (long or short) of the target and flankers in order to test the effects of target–object integration and target presentation time on object-based attention. The results showed that an object-based effect could appear when the target was a bite, no matter whether the target presentation time was long or short; but when the target was a letter, an object-based effect was only observed when the target presentation time was short enough. These findings provide additional evidence supporting the argument of attentional spreading in object-based attention. However, this spreading is moderated jointly by target–object integration and the target presentation time.     

大学新生时间管理倾向、手机依赖与无聊倾向的关系：一项交叉滞后研究

在3个月的时间内对425名大学新生进行3次追踪测量，以考察时间管理倾向、手机依赖与无聊倾向之间的因果顺序和发展变化趋势。结果发现：（1）大学新生的无聊倾向与时间管理倾向呈同时性和继时性的负相关，并与手机依赖水平呈同时性和继时性的正相关。（2）T1和T2的无聊倾向分别正向预测T2和T3的手机依赖，并分别负向预测T2和T3的时间管理倾向；T1的时间管理倾向负向预测T2的无聊倾向；T2的手机依赖正向预测T3的无聊倾向。结论：无聊倾向分别与手机依赖、时间管理倾向之间存在相互预测关系。     

A cross‐cultural analysis of German,Chinese and Indian consumers' perception of web site adaptation

• The aim of this study is to provide empirical evidence, using the theory of planned behavior, as to whether local consumers prefer culturally adapted web sites or standardized web sites The study contributes to the existing literature by showing that consumers from Germany, China, and India prefer web sites adapted to their local culture, and that culture influences consumer beliefs, attitudes, and purchase intention on the web.

Pilocarpine seizures cause age-dependent impairment in auditory location discrimination

Children who have status epilepticus have continuous or rapidly repeating seizures that may be life-threatening and may cause life-long changes in brain and behavior. The extent to which status epilepticus causes deficits in auditory discrimination is unknown. A naturalistic auditory location discrimination method was used to evaluate this question using an animal model of status epilepticus. Male Sprague-Dawley rats were injected with saline on postnatal day (P) 20, or a convulsant dose of pilocarpine on P20 or P45. Pilocarpine on either day induced status epilepticus; status epilepticus at P45 resulted in CA3 cell loss and spontaneous seizures, whereas P20 rats had no cell loss or spontaneous seizures. Mature rats were trained with sound-source location and sound-silence discriminations. Control (saline P20) rats acquired both discriminations immediately. In status epilepticus (P20) rats, acquisition of the sound-source location discrimination was moderately impaired. Status epilepticus (P45) rats failed to acquire either sound-source location or sound-silence discriminations. Status epilepticus in rat causes an age-dependent, long-term impairment in auditory discrimination. This impairment may explain one cause of impaired auditory location discrimination in humans.     

The mediating role of self-efficacy in the development of entrepreneurial intentions

The purpose of this study was to investigate the mediating role of self-efficacy in the development of students' intentions to become entrepreneurs. The authors used structural equation modeling with a sample of 265 master of business administration students across 5 universities to test their hypotheses. The results showed that the effects of perceived learning from entrepreneurship-related courses, previous entrepreneurial experience, and risk propensity on entrepreneurial intentions were fully mediated by entrepreneurial self-efficacy. Contrary to expectations, gender was not mediated by self-efficacy but had a direct effect such that women reported lower entrepreneurial career intentions. The authors discuss practical implications and directions for future research.     

Evaluation of two methods of prompting drivers to use specific exits on conflicts between vehicles at the critical exit

The Florida Department of Transportation used a series of changeable-message signs that functioned as freeway guide signs to divert traffic to Universal Theme Park via one of two eastbound exits based on traffic congestion at the first of the two exits. An examination of crashes along the entire route indicated a statistically significant increase in crashes at the first eastbound exit following the actuation of the system. Furthermore, all of the crashes occurred in close proximity to the exit gore (the crosshatched area at exits that drivers are not supposed to enter or traverse) at the first exit. In Experiment 1, behavioral data were collected using an alternating treatments design. These data revealed that reassigning the exit signs was effective in producing a change in the percentage of drivers using each of the two exits. These data also showed that the reassignment of the theme park exit was associated with an increase in the percentage of motor vehicle conflicts that consisted of vehicles cutting across the exit gore. An analysis revealed that the method used for switching the designated or active theme park exit on the series of changeable-message signs led to the presentation of conflicting messages to some motorists, thus resulting in erratic driving behavior (cutting across the exit gore). In Experiment 2, the treatment evaluated the use of a phased method of switching the designated theme park exit to eliminate the delivery of conflicting messages. The new method for switching the designated theme park exit was not associated with an increase in motorists cutting across the exit gore.     

现代新儒学基本理论的自我消解

现代新儒家的基本理论主张可概括为 :儒学主流说、儒家道统说、新内圣外王之道、良知自我坎陷说、儒学复兴论。现代新儒学第三代重要代表人物已经偏离或放弃了这些基本的理论和主张 ,走上了文化多元化之路。这无疑意味着现代新儒学基本理论的自我消解。现在 ,这股文化思潮的高峰已经过去 ,已经成为历史。     

小学4～6年级儿童对同伴亲社会行为动机的评价

随机选取衡水市358名4～6年级小学生,采用问卷法探讨其对同伴做出帮助行为、分享行为、合作行为、安慰行为等四种亲社会行为动机的评价。结果发现。这些儿童认为其同伴的亲社会动机主要是“乐于助人”、“为他人着想”、“应该这么做”、“获得好朋友”;他们普遍认为同伴的亲社会动机是出于对他人和集体利益的考虑：总体上女生比男生更倾向于从利他和集体利益的角度评价同伴的亲社会动机,特别在合作行为和安慰行为方面;各年级的评价之间没有显著差异。
