“己之所欲”还是“成人之美”？解释水平视角下个体赠送-接受礼物的偏好不对称性

解释水平理论被广泛应用于消费研究领域。本研究以解释水平理论为理论基础,采用情境问卷调查方法,通过5个实验探讨个体赠送与接受礼物时是否存在性别和角色偏好的不对称性。结果发现,一般情境下,受性别因素影响,男生偏好赠送和接受工具性礼物,女生偏好赠送和接受表达性礼物。但随着心理距离（社会距离和空间距离）的拉近,个体的解释水平降低,更关心他人的喜好和需求,赠送者会更基于接收者的偏好进行礼物选择。     

论公共行政管理的伦理基础——一个公共伦理分析视角

当代中国正处在以城市化为主导的社会转型的关键时期,社会出现了种种不协调,需要相应价值尺度来引导。行政管理本身不是最终目的,它是传达人民的需求与愿望,并保证这些需求和愿望能够通过国家控制反映出来。长期以来,行政管理学界高扬效率、忽视伦理的主题定位,在一定程度上阻碍了行政管理学研究向纵深领域的发展。公共行政管理从产生时起就与某种伦理价值观相联系;公共行政管理的主要伦理规范有公益至上、有害不为、慎用权力、社会责任、平等竞争、增进信任。这些规范为公共行政管理奠定了伦理基础。     

社会生物学伦理观评介

威尔逊通过社会生物学的研究,指出动物的社会行为有其生物学的基础。他认为人类的利他主义伦理也同样有着生物学基础,从而提出了以生物行为科学解释伦理本质的伦理观。社会生物学伦理观,是一座联接伦理学与自然科学的桥梁。当今时代,进一步深入研究社会生物学伦理观,对于完善伦理学的科学基础,对于如何恰当地开展社会伦理教育都具有重要的意义。     

Asian American-white American differences in expressions of social anxiety: a replication and extension

This study examined whether Asian American-White American differences on a trait measure of social anxiety extend to nonverbal behavior and to reports of anxiety-related emotions during a 3-min social performance task. Forty Asian Americans and 40 White Americans completed a trait measure of social anxiety and rated their emotions before, and immediately after, a social performance task. Their videotaped behavior was coded using microlevel behavioral codes (e.g., gaze avoidance, fidgeting). Results indicated that Asian Americans reported more anxiety than White Americans on the trait measure and on the emotion rating scales but that they did not differ substantially on microlevel behavioral indexes of social anxiety. Implications of ethnic variations in the patterns of anxious responding are discussed.     

Movement substructures change as a function of practice in children and adults

An experiment is reported in which participants at 6 (n = 20), 9 (n = 20), and 24 years (n = 20) of age either received or did not receive practice on a rapid aiming task using the arm and hand. The purpose of the experiment was to document the changes in movement substructures (in addition to movement time) as a function of practice. After receiving 10 baseline trials, subjects in the practice groups received 30 practice trials followed by 10 retention trials on each of 5 days, while subjects in the no-practice group had only baseline and retention trials. Retention-only trials were divided into primary (reflecting the ballistic controlled part of the movement) and secondary (reflecting corrective movement adjustments) submovements. In addition, jerk (the 3rd derivative of movement displacement) was calculated as an estimate of the smoothness of the movement. Participants increased the primary submovement as a function of practice; however, the increases were substantially larger in the children (25-30%) than in the adults (10%). Participants also decreased jerk as a function of practice and the decreases were greater in children than in adults. The results suggest that with practice the primary submovement is lengthened so that it ends nearer the target, especially in children. Associated with the primary submovement covering a larger percentage of the movement length and time, movements became smoother.     

Facing faces: studies on the cognitive aspects of physiognomy

Physiognomy, the art of reading personality traits from faces, dates back to ancient Greece, and is still very popular. The present studies examine several aspects and consequences of the process of reading traits from faces. Using faces with neutral expressions, it is demonstrated that personality information conveyed in faces changes the interpretation of verbal information. Moreover, it is shown that physiognomic information has a consistent effect on decisions, and creates overconfidence in judgments. It is argued, however, that the process of "reading from faces" is just one side of the coin, the other side of which is "reading into faces." Consistent with the latter, information about personality changes the perception of facial features and, accordingly, the perceived similarity between faces. The implications of both processes and questions regarding their automaticity are discussed.     

Use of photic feedback as an adjunct treatment in a case of Miller Fisher syndrome

Photic Feedback treatment of a patient diagnosed with Miller Fisher syndrome has resulted in the rapid and permanent remission of symptoms. During Photic Feedback treatment, the CD20 appeared to be slightly increased. This may have been associated with changes in humoral immunity. The present clinical observation of a single patient suggests that Photic Feedback treatment should be investigated as a possible adjunct therapy for patients who suffer from polyneuropathies, such as Miller Fisher syndrome, within a carefully controlled clinical trial.     

Reliability and dimensionality of judgments of visually textured materials

We extended perceptual studies of the Brodatz set of textured materials. In the experiments, texture perception for different texture sets, viewing distances, or lighting intensities was examined. Subjects compared one pair of textures at a time. The main task was to rapidly rate all of the texture pairs on a number scale for their overall dissimilarities first and then for their dissimilarities according to six specified attributes (e.g., texture contrast). The implied dimensionality of perceptual texture space was usually at least four, rather than three. All six attributes proved to be useful predictors of overall dissimilarity, especially coarseness and regularity. The novel attribute texture lightness, an assessment of mean surface reflectance, was important when viewing conditions were wide-ranging. We were impressed by the general validity of texture judgments across subject, texture set, and comfortable viewing distances or lighting intensities. The attributes are nonorthogonal directions in four-dimensional perceptual space and are probably not narrow linear axes. In a supplementary experiment, we studied a completely different task: identifying textures from a distance. The dimensionality for this more refined task is similar to that for rating judgments, so our findings may have general application.     

Inhibitory tagging in visual search can be found if search stimuli remain visible

Klein (1988) reported that inhibitory tagging (i.e., inhibition of return in visual search) made reaction times for the detection of small probes increase at locations where there had previously been rejected items in serial visual search. It is reasonable that the attended and rejected locations are inhibited. However, subsequent studies did not support Klein's idea. In these studies, inhibitory tagging was tested after removing the items from the search tasks. The paradigms in these studies were not appropriate for testing an object-based inhibitory effect because the objects (i.e., items) were removed from the display. In the present study, we found that evidence of inhibitory tagging could be observed only when the items of the search tasks were maintained until the responses for the small probes were made. This appeared to be an object-based effect.
