Associations between self-rated health and the assessments of anchoring vignettes in cardiovascular patients

Background/ObjectiveAssessments of health can be biased by response shift effects. One method for detecting such effects is the use of anchoring vignettes. The aim of this study was to analyze the relationship between participants’ self-assessed health state and their assessments of these vignettes.MethodA total of 342 cardiovascular patients assessed their own state of health on a 0-100 visual analogue scale. The patients additionally assessed two vignettes featuring fictional persons suffering from specific complaints. A sample of the general population (N = 1,236) served as controls.ResultsThe participants rated the health state of the vignette character featuring physical problems as being significantly better than the general population did (effect size: d = 0.53). The group difference in the assessment of the vignette featuring primarily mental health problems was lower (d = -0.17). Participants’ assessments of the vignettes were positively correlated with their assessments of their own health state (r = .26 and r = .10) and with several quality of life variables.ConclusionsAnchoring vignettes are a useful tool for detecting response shift effects.     

No face-like processing for objects-of-expertise in three behavioural tasks

In the debate between expertise and domain-specific explanations of "special" processing for faces, a common belief is that behavioural studies support the expertise hypothesis. The present article refutes this view, via a combination of new data and review. We tested dog experts with confirmed good individuation of exemplars of their breed-of-expertise. In all experiments, standard results were confirmed for faces. However, dog experts showed no face-like processing for dogs on three behavioural tasks (inversion; the composite paradigm; and sensitivity to contrast reversal). The lack of holistic/configural processing, indicated in the first two of these tests, is shown by review to be consistent rather than inconsistent with previous studies of objects-of-expertise.     

Dynamic facial expressions are processed holistically,but not more holistically than static facial expressions

There is evidence that facial expressions are perceived holistically and featurally. The composite task is a direct measure of holistic processing (although the absence of a composite effect implies the use of other types of processing). Most composite task studies have used static images, despite the fact that movement is an important aspect of facial expressions and there is some evidence that movement may facilitate recognition. We created static and dynamic composites, in which emotions were reliably identified from each half of the face. The magnitude of the composite effect was similar for static and dynamic expressions identified from the top half (anger, sadness and surprise) but was reduced in dynamic as compared to static expressions identified from the bottom half (fear, disgust and joy). Thus, any advantage in recognising dynamic over static expressions is not likely to stem from enhanced holistic processing, rather motion may emphasise or disambiguate diagnostic featural information.     

The composite face illusion: A whole window into our understanding of holistic face perception

Two identical top halves of a face are perceived as being different when their bottom halves belong to different faces, showing that the parts of a face cannot be perceived independently from the whole face. When this visual illusion is inserted in a matching task, observers make more mistakes and/or are slower at matching identical top face halves aligned with different bottom halves than when the bottom halves are spatially offset: The composite face effect. This composite face paradigm has been used in more than 60 studies that have provided information about the specificity and nature of perceptual integration between facial parts (“holistic face perception”), the impairment of this process in acquired prosopagnosia, its developmental course, temporal dynamics, and neural basis. Following a review of the main contributions made with the paradigm, I explain its rationale and strengths, and discuss its methodological parameters, making a number of proposals for its optimal use and refinement in order to improve our understanding of holistic face perception. Finally, I explain how this standard composite face paradigm is fundamentally different than the application to facial parts of a congruency/interference paradigm that has a long tradition in experimental psychology since Stroop (1935), and which was originally developed to measure attentional and response interference between different representations rather than perceptual integration. Moreover, a version of this congruency/interference paradigm used extensively over the past years with composite faces lacks a baseline measure and has decisional, attentional, and stimulus confounds, making the findings of these studies impossible to interpret in terms of holistic perception. I conclude by encouraging researchers in this field to concentrate fully on the standard composite face paradigm, gaze contingency, and other behavioural measures that can help us take one of the most important challenges of visual perception research: Understanding the neural mechanisms of holistic face perception.     

Holistic face perception: Mind the gap!

The most widely used measurement of holistic face perception, the composite face effect (CFE), is challenged by two apparently contradictory goals: having a defined face part (i.e., the top half), and yet perceiving the face as an integrated unit (i.e., holistically). Here, we investigated the impact of a small gap between top and bottom face halves in the standard composite face paradigm, requiring matching of sequentially presented top face halves. In Experiment 1, the CFE was larger for no-gap than gap stimuli overall, but not for participants who were presented with gap stimuli first, suggesting that the area of the top face half was unknown without a gap. This was confirmed in Experiment 2, in which these two stimulus sets were mixed up: the gap stimuli thus provided information about the area of a top face half and the magnitude of the CFE did not differ between stimulus sets. These observations indicate that the CFE might be artificially inflated in the absence of a stimulus cue that objectively defines a border between the face halves. Finally, in Experiment 3, observers were asked to determine which of two simultaneously presented faces was the composite face. Perceptual judgements for no-gap stimuli approached ceiling; however, with a gap, participants were almost unable to distinguish the composite face from a veridical face. This effect was not only due to low-level segmentation cues at the border of no-gap face halves, because stimulus inversion decreased performance in both conditions. This result indicates that the two halves of different faces may be integrated more naturally with a small gap that eliminates an enhanced contrast border. Collectively, these observations suggest that a small gap between face halves provides an objective definition of the face half to match and is beneficial for valid measurement of the behavioural CFE.

基于虚拟情境锚定法的基层政府信任现状调查与影响因素分析

由于政府信任概念的复杂性及其评价的敏感性,传统一般化的政府信任的测量难以避免评价尺度偏差或社会期望偏差。研究对647名浙江省居民进行网络问卷调查并分析,运用虚拟情境锚定法校正偏差,从而探究民众对基层政府信任现状以及影响因素。结果表明：（1）使用“虚拟情境锚定法”后,“信任”和“完全信任”的总比例为33.54%,较校正前降低了36.01%,即验证了评价尺度偏差与社会期望偏差的存在。（2）校正后的民众基层政府信任水平下降,但整体仍处于中等水平;（3）民众的基层政府信任水平受到年龄、月收入水平、政治面貌、教育程度不同程度的影响。
