时间参照对绿色消费的影响：环保意识和产品环境怀疑的调节作用

绿色消费虽然受到越来越多的关注,但消费者的绿色承诺很难转化为实际的购买行为,出现了消费者的不作为现象。本研究试图探讨时间参照对消费者不作为的影响以及环保意识是否能够有效抑制这种不作为。研究发现,消费者在近期情境下对绿色产品的购买意愿低于远期,出现了绿色消费不作为现象,即个体更倾向于在将来而不是现在购买绿色产品。尤为重要的是,环保意识对消费者不作为的弱化作用受制于个体的产品环境怀疑：产品坏境怀疑较低时环保意识的弱化作用明显,而产品环境怀疑较高时环保意识的弱化作用则不存在。     

基于选项层面的认知诊断非参数方法

充分挖掘选择题(Multiple-Choice, MC)的诊断信息受到了较多关注, 将干扰项信息考虑在内可以提升诊断精度。为了弥补参数模型基于大样本才能获得可靠估计的不足, 以及适用于班级水平的小样本诊断测验情境, 本研究提出了非参数的多选题诊断方法。模拟和实证研结果表明：(1)当MC测验中题目参数不存在较大差异时, ${{d}_{\text{ph}-\text{MC}}}$法在多数情况下表现优于参数类诊断模型。(2)当MC测验中题目参数存在较大差异时, ${{d}_{ph-MC}}$法的表现最优。(3)实证研究中非参数方法和参数类模型的分类一致性程度较高, ${{d}_{\text{ph}-\text{MC}}}$距离法估计得到的考生属性总体掌握程度与总分相关最高。最后, 基于MC诊断测验的特点提出了若干研究方向。     

心理距离对大学生职业决策偏好的影响

职业决策对大学生职业生涯发展具有重要意义。心理距离作为个体决策的重要影响因素之一,是否也影响着大学生的职业决策偏好？研究通过4个实验,采用2（心理距离：远、近）*2（性别：男、女）混合实验设计,以大学生为研究对象,探讨了心理距离（空间距离、时间距离、社会距离、假设性）和性别对职业决策偏好的影响。研究发现：(1)大学生在心理距离远的情境下更偏好选择稳定、职业声望高的职业;在心理距离近的情境下更偏好选择薪资高、专业对口的职业。（2）空间距离、时间距离、社会距离近的情境下,男大学生比女大学生更偏好选择薪资高、专业对口的职业。     

心理长度对二年级儿童数字线估计表征的影响

从心理长度的角度探讨二年级儿童在0~100和0~1000数字范围存在不同表征方式的原因。实验一要求二年级儿童完成长度均为10cm,范围分别为0~100和0~1000的数字线估计任务。实验二要求儿童对长度分别为10cm和18cm,范围均为0~1000的数字线进行估计。结果发现在两个实验中二年级儿童的估计均存在心理长度,但与以往研究的一年级儿童相比,心理长度的范围有所缩小。随着数字范围的增大或长度的减小,儿童的表征方式出现了从线性表征向对数表征的转变趋势。这些结果表明不精确的表征方式可能与心理长度策略的使用有关,心理长度在一定程度上影响了二年级儿童的估计表征方式。     

Examining differences in minority versus majority preschoolers on social categorization and perceived intergroup distance

We examined the differences between majority and minority children (i.e., group membership) on racial categorization and perceived cultural distance, among 4‐ to 6‐year‐old children, in low diversified schools. We used a spontaneous social categorization task using pictures of children from three different racial groups broadly represented in France (Europeans, Black‐, and North‐Africans), and an evaluation of the perceived cultural distance between participants' in‐group and the racial group represented in the picture, adapted to children and based on three factors (language, eating habits, and music). Results revealed an effect of age on racial categorization: the older the children, the more successful they are in this task. They showed a significant effect of the racial group represented in the photos on perceived cultural distance: members of minority groups (i.e., Black‐ and North‐Africans) were evaluated as more different compared to those of the majority group on each of the factors. Finally, we got an interaction between participants' in‐group and the racial group represented in the pictures, for the language factor: members of the majority group perceived as more different photographs representing minorities peers than those representing majority peers, while participants belonging to minority groups perceived no differences between photographs, according to the racial criteria.     

Seeing Like a Geologist: Bayesian Use of Expert Categories in Location Memory

Memory for spatial location is typically biased, with errors trending toward the center of a surrounding region. According to the category adjustment model (CAM), this bias reflects the optimal, Bayesian combination of fine‐grained and categorical representations of a location. However, there is disagreement about whether categories are malleable. For instance, can categories be redefined based on expert‐level conceptual knowledge? Furthermore, if expert knowledge is used, does it dominate other information sources, or is it used adaptively so as to minimize overall error, as predicted by a Bayesian framework? We address these questions using images of geological interest. The participants were experts in structural geology, organic chemistry, or English literature. Our data indicate that expertise‐based categories influence estimates of location memory—particularly when these categories better constrain errors than alternative (“novice”) categories. Results are discussed with respect to the CAM.     

领导-成员交换与情绪枯竭:互惠信念和权力距离导向的作用

结合社会交换理论和角色理论,领导-成员交换关系中下属的回报不仅受到互惠规范的约束,还受到上下级关系权力不对称的影响。因此,将探索互惠信念和权力距离导向单独及交互项对领导-成员交换与情绪枯竭关系的调节作用。采用两个时间点172名员工的匹配数据,运用层级回归对假设进行了检验。结果表明,领导-成员交换(T1)与情绪枯竭(T2)总体上呈显著负向关系。互惠信念(T1)和权力距离导向(T1)单独对领导-成员交换与情绪枯竭关系的调节作用并不显著,但是二者的交互项的调节作用显著。即,领导-成员交换、互惠信念和权力距离导向对情绪枯竭有显著三维交互作用。具体的,高互惠信念和低权力距离导向的员工,领导-成员交换与情绪枯竭呈显著正向关系;高互惠信念和高权力距离导向的员工,领导-成员交换与情绪枯竭呈显著负向关系。研究验证了领导-成员交换过程中互惠规范的作用,表明互惠规范的适用性受到上下级关系特征的影响。     

Finger counting habit and spatial–numerical association in children and adults

Sensory-motor experiences are known to build up concrete and abstract concepts during the lifespan. The present study aimed to test how finger counting habits (right-hand vs. left-hand starters) could influence the spatial–numerical representation in number-to-position (explicit) and digit-string bisection (implicit) tasks. The subjects were Italian primary school children (N = 184, from the first to the fifth year) and adults (N = 42). No general preference for right- or left-starting in the finger counting was found. In the explicit task, right- or left-starting did not affect performance. In the implicit task, the right-hand starters shifted from the left to the right space when bisecting small and large numbers respectively, while the left-hand starters shifted from the right to the left space with higher leftward bias for large numbers. The finger configuration in Italian children and adults influences the spatial–numerical representation, but only when implicit number processing is required by the task.     

Auditory spatial concepts in blind football experts

ObjectivesWe compared the spatial concepts given to sounds' directions by blind football players with both blind non-athletes and sighted individuals.MethodParticipants verbally described the directions of sounds around them by using predefined spatial concept labels, under two blocked conditions: 1) facing front, 2) pointing with the hand towards the stimulus.ResultsBlind football players categorized the directions more precisely (i.e., they used simple labels for describing the cardinal directions and combined labels for the intermediate ones) than the other groups, and their categorization was less sensitive to the response conditions than blind non-athletes. Sighted participants' categorization was similar to previous studies, in which the front and back regions were generally more precisely described than the sides, where simple labels were often used for describing directions around the absolute left and right.ConclusionsThe differences in conceptual categorization of sound directions are a) in sighted individuals, influenced by the representation of the visual space b) in blind individuals, influenced by the level of expertise in action and locomotion based on non-visual information, which can be increased by auditive stimulation provided by blind football training.
