从《游叙弗伦》看苏格拉底的敬神

由苏格拉底之死而引发的苏格拉底敬神之探讨,迄今为止仍为许多研究者孜孜以求。文章试图以柏拉图这篇专门探讨敬神主题的对话《游叙弗伦》为切入点,来考察苏格拉底的敬神。前三节逐一分析该篇对话所探讨的关于敬神的三种定义:1.敬神即做神所做;2.凡神所喜即敬神;3.敬神即在于侍奉神。一则考察习俗敬神观的根据,以及游叙弗伦对这种敬神观的立场,二则从苏格拉底对游叙弗伦的回应来看苏格拉底对这种习俗敬神观的态度。最后一节试图考察苏格拉底自身的敬神态度,以及这种态度与其作为哲人的智慧之间的内在关联。

Tactile contact and evaluation of the toucher

The authors investigated the effect of touch on a person's evaluation of the toucher in a field setting. In the context of selling a 2nd-hand car, the authors instructed a male seller to slightly touch (or not touch) a man who was interested in the car. After the participant left the seller, a female confederate solicited him, asking him to evaluate the car seller on various dimensions. The results showed that for each dimension that the participants evaluated, the touch condition was associated with statistically higher positive evaluations of the toucher than the no-touch control condition.     

THE MEASUREMENT AND FURTHER CONCEPTUALIZATION OF TEACHER COMMUNICATION CONCERN

This study reported the development of a set of scales to measure the self, task, and impact dimensions of teacher communication concern. Three stages of instrument development were described: item construction, testing of the hypothesized factor structure, and reliability and validity information. The result was a 15-item instrument with three subscales. In an effort to refine the conceptualization of teacher communication concern, a secondary purpose of the study was to examine the relationship of teacher communication concern to two variables: anxiety about teaching and attitude toward teaching as a career. Results were that teacher communication concern was not related to anxiety about teaching, but was positively related to attitude about teaching.     

The influence of materialism and ideal body internalization on body‐dissatisfaction and body‐shaping behaviors of young men and women: Support for the Consumer Culture Impact Model

Exposure to media images of the ‘body‐perfect’ ideal has been partly blamed for the pursuit of thinness among women and muscularity among men. Research has largely overlooked the materialistic messages frequently associated with these images. We present findings from two studies with Icelandic students aged 18–21, one focusing on young women (n = 303) and one on young men (n = 226), which test associations of materialistic and body‐perfect ideals with body dissatisfaction and excessive body shaping behaviors. In both studies, the internalization of materialistic values is strongly linked to the internalization of body‐perfect ideals: the thin‐ideal for young women, and the muscular‐ideal for young men. A materialist value orientation also predicted body dissatisfaction in both studies, and was linked to body shaping behaviors, albeit differently for young women and men. Thus, the research identifies materialism as a further correlate of both body dissatisfaction and excessive body‐shaping behaviors. The findings support Dittmar's ( 2008 ) Consumer Culture Impact Model, which proposes that the body‐perfect and ‘material good life’ ideals jointly impact well‐being.     

The role of verbal memory in regressions during reading is modulated by the target word’s recency in memory

During reading, a number of eye movements are made backward, on words that have already been read. Recent evidence suggests that such eye movements, called regressions, are guided by memory. Several studies point to the role of spatial memory, but evidence for the role of verbal memory is more limited. In the present study, we examined the factors that modulate the role of verbal memory in regressions. Participants were required to make regressions on target words located in sentences displayed on one or two lines. Verbal interference was shown to affect regressions, but only when participants executed a regression on a word located in the first part of the sentence, irrespective of the number of lines on which the sentence was displayed. Experiments 2 and 3 showed that the effect of verbal interference on words located in the first part of the sentence disappeared when participants initiated the regression from the middle of the sentence. Our results suggest that verbal memory is recruited to guide regressions, but only for words read a longer time ago.     

Ain’t sure who to blame: Metacognitive influences on appraisal–emotion processes

In this research, we propose that emotions are affected not only by appraisals, but also by a metacognitive sense of confidence versus doubt over the appraisals. Focusing on core-relational themes (CRTs), higher-order appraisals comprising the combined meaning of several appraisals, we predicted and found evidence, over two studies, that the effect of a CRT on the corresponding emotion is stronger if one feels confident about the validity of the CRT compared to feeling doubtful. In Study 1, CRT was manipulated by recall and in Study 2, CRT was manipulated in vivo. Both designs produced consistent support for the hypotheses. These findings demonstrate the need to consider metacognitive processes in understanding the effects of appraisals on emotions.     

“Deafness” effects in detecting alterations to auditory feedback during sequence production

Past research has shown that when discrete responses are associated with a perceptual goal, performers may have difficulty detecting stimuli that are commensurate with that goal. Three experiments are reported here that test whether such effects extend to sequence production. In Experiment 1, participants performed 8-note melodies repeatedly, and on each trial a single tone could be altered with respect to its pitch and/or synchrony with actions. Results suggested a selective deficit of detection when feedback pitch was unchanged and the event was slightly delayed. Experiment 2 showed that this “deafness” to feedback is limited to rhythmic motor tasks that require sequencing, in that similar effects did not emerge when participants produced pitch sequences by tapping a single key repeatedly. A third experiment demonstrated similar results to Experiment 1 when the mapping of keys to pitches on the keyboard was reversed. Taken together, results suggest a selective deafness to response-congruent delayed feedback, consistent with the idea that performers suppress previously planned events during production.     

Auditory temporal pattern learning by songbirds using maximal stimulus diversity and minimal repetition

The sequential patterning of complex acoustic elements is a salient feature of bird song and other forms of vocal communication. For European starlings (Sturnus vulgaris), a songbird species, individual vocal recognition is improved when the temporal organization of song components (called motifs) follows the normal patterns of each singer. This sensitivity to natural motif sequences may underlie observations that starlings can also learn more complex, unnatural motif patterns. Alternatively, it has been proposed that the apparent acquisition of abstract motif patterning rules instead reflects idiosyncrasies of the training conditions used in prior experiments. That is, that motif patterns are learned not by recognizing differences in temporal structures between patterns, but by identifying serendipitous features (e.g., acoustical cues) in the small sets of training and testing stimuli used. Here, we investigate this possibility, by asking whether starlings can learn to discriminate between two arbitrary motif patterns, when unique examples of each pattern are presented on every trial. Our results demonstrate that abstract motif patterning rules can be acquired from trial-unique stimuli and suggest that such training leads to better pattern generalization compared with training with much smaller stimulus subsets.     

Crystallization acceleration of amorphous Fe40Ni40P14B6 alloy by fluxing technique

The effect of fluxing on the structure and the crystallization of amorphous Fe₄₀Ni₄₀P₁₄B₆ alloy has been studied. Subjected to fluxing, the incubation time upon isothermal crystallization decreases, whereas, the onset crystallization temperature upon non-isothermal crystallization (with constant heating rate) decreases, and crystallization peaks become less sharp. via structural characterization, it is considered that fluxing promotes relaxation of the system; the atomic structure becomes more similar to the corresponding crystallized phase, thus alleviating the transient effect on nucleation and accelerates the crystallization.
