Children's comprehension of visual formal features in television programs

A review of previous studies on children's comprehension of visual formal features did not warrant predictions about children's understanding of the formal features as used in three items from Sesamstraat, the Dutch version of Sesame Street. Therefore, a study was designed in which 45 children in the age range of 4–6 years watched the items and were interviewed. In the first item, a split screen was used to visualize simultaneity of actions. The second item used a subjective camera to suggest the construction of a home video by one of the characters. Version 1 of this item did not show the character while making home video, whereas Version 2 did show the character while filming. The third item contained a dissolve (Version 1) or a cut (Version 2) to indicate the end of a dream. A general conclusion was that although older children (mean AGE=5.9 years) understood the visual formal features better than younger children (mean AGE=4.4 years), the extent to which children in both age groups understood the visual formal features appeared to vary between items and versions. Most children in both age groups understood the split screen in the first item. The younger age group did not understand the subjective camera if the making of the home video was not shown. Both the younger and the older age group understood the version with the cut better than the original version with the dissolve. In the discussion, the question was addressed what the findings of this study and previous studies teach us about children's understanding of visual formal features in general.     

Similarity and difference in the processing of same- and other-race faces as revealed by eye tracking in 4- to 9-month-olds

Fixation duration for same-race (i.e., Asian) and other-race (i.e., Caucasian) female faces by Asian infant participants between 4 and 9 months of age was investigated with an eye-tracking procedure. The age range tested corresponded with prior reports of processing differences between same- and other-race faces observed in behavioral looking time studies, with preference for same-race faces apparent at 3 months of age and recognition memory differences in favor of same-race faces emerging between 3 and 9 months of age. The eye-tracking results revealed both similarity and difference in infants’ processing of own- and other-race faces. There was no overall fixation time difference between same race and other race for the whole face stimuli. In addition, although fixation time was greater for the upper half of the face than for the lower half of the face and trended higher on the right side of the face than on the left side of the face, face race did not impact these effects. However, over the age range tested, there was a gradual decrement in fixation time on the internal features of other-race faces and a maintenance of fixation time on the internal features of same-race faces. Moreover, the decrement in fixation time for the internal features of other-race faces was most prominent on the nose. The findings suggest that (a) same-race preferences may be more readily evidenced in paired comparison testing formats, (b) the behavioral decline in recognition memory for other-race faces corresponds in timing with a decline in fixation on the internal features of other-race faces, and (c) the center of the face (i.e., the nose) is a differential region for processing same- versus other-race faces by Asian infants.     

孙诒让管子研究之特色与影响

道咸以来,考据学渐衰,《管子》研究也随之进入了平缓时期。生活于清末的学者孙诒让,在《管子》研究史上承前启后,乃清末考据学之杰出者。他的《札迻》引经据典,校勘辨疑,极有乾嘉之遗风。特别是其中的《管子》部分,充分体现其学术思想,无论内容还是特色,很有典型性。后世学者校读《管子》,多以不同版本对勘,再参以前人之成果,注重多重证据,就是受了孙诒让《管子》研究的影响。     

梁启超《管子》研究的特色与影响

梁启超是清末民初的著名学者,一身兼有旧学和新学影响,在《管子》研究上也有所建树。他的《管子》研究,正处于变法维新时期,他以今文经学的宗旨为指导思想,通过对中西方制度等方面的对比,试图找到改变中国命运的一剂良方。《管子》是礼法并重、制度以刚柔相济为要,故而十分符合梁启超的初衷。他结合自己的学术研究,通过《管子》书来评价管仲,并突显了《管子》的经济与法治思想,这是其《管子》研究的特色,并在《管子》真伪的讨论、义理的研究和管子形象的提升上对后世产生深远的影响。     

Experienced utility: Utility theory from Jeremy Bentham to Daniel Kahneman

Utility is sometimes defined as being a way to summarise choice, and sometimes as the benefit we get from experience. In economics, the twentieth century saw the former definition supplant the latter. Recent research by Kahneman and colleagues has undertaken to resurrect the latter definition under the heading of “experience utility”. In this paper I give a brief history of the concept of experience utility, and examine three normative claims that have been made about it: that it avoids the problem of dependent utilities, that it can be measured from an invariant “zero point”, and that it allows intrapersonal comparison of utilities.     

Transfer to intermediate forms following concept discrimination by pigeons: chimeras and morphs

Two experiments examined pigeons' generalization to intermediate forms following training of concept discriminations. In Experiment 1, the training stimuli were sets of images of dogs and cats, and the transfer stimuli were head/body chimeras, which humans tend to categorize more readily in terms of the head part rather than the body part. In Experiment 2, the training stimuli were sets of images of heads of dogs and cats, and the intermediate stimuli were computer-generated morphs. In both experiments, pigeons learned the concept discrimination quickly and generalized with some decrement to novel instances of the categories. In both experiments, transfer tests were carried out with intermediate forms generated from both familiar and novel exemplars of the training sets. In Experiment 1, the pigeons' transfer performance, unlike that of human infants exposed to similar stimuli, was best predicted by the body part of the stimulus when the chimeras were formed from familiar exemplars. Spatial frequency analysis of the stimuli showed that the body parts were richer in high spatial frequencies than the head parts, so these data are consistent with the hypothesis that categorization is more dependent on local stimulus features in pigeons than in humans. There was no corresponding trend when the chimeras were formed from novel exemplars. In Experiment 2, when morphs of training stimuli were used, response rates declined smoothly as the proportion of the morph contributed by the positive stimulus fell, although results with morphs of novel stimuli were again less orderly.     

Lexically-driven syntactic priming

Syntactic priming studies demonstrate that exposure to a particular syntactic structure leads speakers to reproduce the same structure in subsequent utterances. Explanations for this phenomenon rely on either the retrieval of morphosyntactic features associated with the verb in the prime sentence or the preservation of the mapping between message and word sequences in the prime sentence. Two experiments test the featural account of syntactic priming. We used single word primes to investigate the dative alternation in German (Experiment 1) and Dutch (Experiment 2). Native speakers read ditransitive verbs that are restricted either to the prepositional (dative) or double object construction, followed by pictures that can be described with either structure. We find that a single verb in isolation is sufficient to bias speakers' production preferences supporting lexically-driven accounts of syntactic priming.     

Ethical Phenomenology and Metaethics

In recent times, comments have been made and arguments advanced in support of metaethical positions based on the phenomenology of ethical experience – in other words, the feel that accompanies our ethical experiences. In this paper I cast doubt on whether ethical phenomenology supports metaethical positions to any great extent and try to tease out what is involved in giving a phenomenological argument. I consider three such positions: independent moral realism (IMR), another type of moral realism – sensibility theory – and noncognitivism. Phenomenological arguments have been used in support of the first two positions, but my general claim is that ethical phenomenology supports no metaethical position over any other.I discuss two types of phenomenological argument that might be offered in support of different types of moral realism, although I couch my debate in terms of IMR. The first argument asserts that ethical properties are not experienced in the way that rivals to IMR say we experience them. Against this I claim that it is odd to think that one could experience ethical properties as any metaethical theory characterizes them. The second argument is more complicated: the general thought is that an adequate metaethical theory should not distort our ethical experience unduly. I consider one aspect of our ethical experience – that there is some ethical authority to which our judgements answer – in order to illustrate this idea. I discuss why IMRealists might think that this phenomenon supports their position. Against them I claim that other metaethical positions might be able to accommodate the phenomenon of ethical authority. Even if they cannot, then, secondly, I argue that there are other aspects of our ethical experience that sit more naturally with other metaethical positions. Hence, one cannot argue that ethical phenomenology as a whole supports one theory over any others.     

The Silent Treatment? Changes in patient emotional expression after silence

Psychotherapy can be an emotionally laden conversation, where both verbal and nonverbal interventions may impact the therapeutic process. Prior research has postulated mixed results regarding how clients emotionally react following a silence after the therapist is finished talking, potentially due to studying a limited range of silences with primarily qualitative and self-report methodologies. A quantitative exploration may illuminate new findings. Utilising research and automatic data processing from the field of linguistics, we analysed the full range of silence lengths (0.2–24.01 s), and measures of emotional expression—vocally encoded arousal and emotional valence from the works spoken—of 84 audio recordings of Motivational Interviewing sessions. We hypothesised that both the level and the variance of client emotional expression would change as a function of silence length; however, due to the mixed results in the literature, the direction of emotional change was unclear. We conducted a multilevel linear regression to examine how the level of client emotional expression changed across silence length, and an ANOVA to examine the variability of client emotional expression across silence lengths. Results of both analyses indicated that as silence length increased, emotional expression largely remained the same. Broadly, we demonstrated a weak connection between silence length and emotional expression, indicating no persuasive evidence that silence leads to client emotional processing and expression.
