Additive conjoint isotonic probabilistic models (ADISOP)

The ISOP-model or model of twodimensional or bi-isotonicity (Scheiblechner, 1995) postulates that the probabilities of ordered response categories increase isotonically in the order of subject ability and item easiness. Adding a conventional cancellation axiom for the factors of subjects and items gives the ADISOP model where the c.d.f.s of response categories are functions of an additive item and subject parameter and an ordinal category parameter. Extending cancellation to the interactions of subjects and categories as well as of items and categories (independence axiom of the category factor from the subject and item factor) gives the CADISOP model (completely additive model) in which the parallel c.d.f.s are functions of the sum of subject, item and category parameters. The CADISOP model is very close to the unidimensional version of the polytomous Rasch model with the logistic item/category characteristic(s) replaced by nonparametric axioms and statistics. The axioms, representation theorems and algorithms for model fitting of the additive models are presented.     

Sex differences in functional cerebral asymmetries in a repeated measures design

The aim of the present study was to analyze whether task repetitions which are an inevitable part of repeated measures designs might induce performance alterations specific for gender and hemisphere. Male and female subjects conducted twice a lexical decision, a polygon recognition, and a face discrimination task as a visual half field paradigm with the two experimental sessions repeated by 2 weeks. The results show that only in female subjects can a session effect for the lexical decision and the polygon recognition task be demonstrated which is hemisphere specific. Thus, repeated measures designs seem to have a gender- and hemisphere-specific effects of their own which could confound with other variables under study.     

Haptic face identification activates ventral occipital and temporal areas: an fMRI study

Many studies in visual face recognition have supported a special role for the right fusiform gyrus. Despite the fact that faces can also be recognized haptically, little is known about the neural correlates of haptic face recognition. In the current fMRI study, neurologically intact participants were intensively trained to identify specific facemasks (molded from live faces) and specific control objects. When these stimuli were presented in the scanner, facemasks activated left fusiform and right hippocampal/parahippocampal areas (and other regions) more than control objects, whereas the latter produced no activity greater than the facemasks. We conclude that these ventral occipital and temporal areas may play an important role in the haptic identification of faces at the subordinate level. We further speculate that left fusiform gyrus may be recruited more for facemasks than for control objects because of the increased need for sequential processing by the haptic system.     

The social-encoding benefit in face recognition is generalized to other-race faces

Faces are visual stimuli that convey rich social information. Previous experiments found better recognition for faces that were evaluated based on their social traits than on their perceptual features during encoding. Here, we ask whether this social-encoding benefit in face recognition is also found for categories of faces that we have no previous social experience with, such as other-race faces. To answer this question, we first explored whether social and perceptual evaluations for other-race faces are consistent and valid. We then asked whether social evaluations during encoding improve recognition for other-race faces. Results show that social and perceptual evaluations of own- and other-race faces were valid. We also found high agreement in social and perceptual evaluations across individuals from different races. This indicates that evaluations of other-race faces are not random but meaningful. Furthermore, we found that social evaluations facilitated face recognition regardless of race, demonstrating a social-encoding benefit for both own- and other-race faces. Our findings highlight the role of social information in face recognition and show how it can be used to improve recognition of categories of faces that are hard to recognize due to lack of experience with them.     

Socio-cognitive,expertise-based and appearance-based accounts of the other-‘race’ effect in face perception: A label-based systematic review of neuroimaging results

Two competing theories explain the other-‘race’ effect (ORE) either by greater perceptual expertise to same-‘race’ (SR) faces or by social categorization of other-‘race’ (OR) faces at the expense of individuation. To assess expertise and categorization contributions to the ORE, a promising—yet overlooked—approach is comparing activations for different other-‘races’. We present a label-based systematic review of neuroimaging studies reporting increased activity in response to OR faces (African, Caucasian, or Asian) when compared with the SR of participants. Hypothetically, while common activations would reflect general aspects of OR perception, ‘race’-preferential ones would represent effects of ‘race’-specific visual appearance. We find that several studies report activation of occipito-temporal and midcingulate areas in response to faces across different other-‘races’, presumably due to high demand on the visual system and category processing. Another area reported in response to all OR faces, the caudate nucleus, suggests the involvement of socio-affective processes and behavioural regulation. Overall, our results support hybrid models—both expertise and social categorization contribute to the ORE, but they provide little evidence for reduced motivation to process OR faces. Additionally, we identify areas preferentially responding to specific OR faces, reflecting effects of visual appearance.     

Intolerance of uncertainty and difficulties in emotion regulation: Proposal for an integrative model of generalized anxiety disorder

Introduction

The Intolerance of Uncertainty Model (IUM) is a well-tested model of generalized anxiety disorder (GAD).

有关自我增强跨文化普遍性的争论

文化自我观点质疑自我增强（self-enhancement）的跨文化普遍性,认为东亚人并非像西方人一样拥有对自我保持积极评价的需要,而是自我提升（self-improvement）。然而,另外一些学者则认为东亚人同样会表现出自我增强,其中“对自我的重要性”被看作是一个重要的中介变量。至此,笔者针对有关自我增强跨文化普遍性的争论做了回顾,并在此基础之上提出从面子角度研究东亚人自尊的建议,以期为澄清此争论提供新的思路与证据

Reaction time as an indicator of stimulus‐response binding in affective judgment of visual stimuli1

Conventional studies on affective meanings have been conducted using the semantic differential technique. Although it offers reasonably valid and reliable measures for the bindings between visual stimuli and affective responses, it is dependent on subjective rating. Thus, the present study examined whether the reaction time (RT) of affective judgments for visual stimuli (color, shape, and facial expression) can be an objective indicator of the strength of stimuli‐response bindings. The results can be summarized as follows: (a) RTs for judging Evaluation were longer regardless of stimulus type; (b) RTs for Activity were shorter regardless of stimulus type; and (c) RTs for Lightness and Sharpness depended on stimulus type. These phenomena are consistent with the findings of previous affective meaning studies, suggesting that the RTs for affective judgments can be useful indicators reflecting the strength of the bindings between stimulus properties and affective meanings across various target stimuli and rating scales.     

Distinct Facial Characteristics Differentiate Communicative Intent of Infant‐Directed Speech

Adults and infants can differentiate communicative messages using the nonlinguistic acoustic properties of infant‐directed (ID) speech. Although the distinct prosodic properties of ID speech have been explored extensively, it is currently unknown whether the visual properties of the face during ID speech similarly convey communicative intent and thus represent an additional source of social information for infants during early interactions. To examine whether the dynamic facial movement associated with ID speech confers affective information independent of the acoustic signal, adults' differentiation of the visual properties of speakers' communicative messages was examined in two experiments in which the adults rated silent videos of approving and comforting ID and neutral adult‐directed speech. In Experiment 1, adults differentiated the facial speech groups on ratings of the intended recipient and the speaker's message. In Experiment 2, an original coding scale identified facial characteristics of the speakers. Discriminant correspondence analysis revealed two factors differentiating the facial speech groups on various characteristics. Implications for perception of ID facial movements in relation to speakers' communicative intent are discussed for both typically and atypically developing infants.
