Is positivity a cue or a response option? Warm glow vs evaluative matching in the familiarity for attractive and not-so-attractive faces

Monin (2003) showed that the attractiveness of a face increases its perceived familiarity regardless of prior exposure, and suggested that this beautiful-is-familiar effect was due to the misattribution to familiarity of the positive affect (or “warm glow”) elicited by attractive faces. This research tests the alternative interpretation that an evaluative match between a positive stimulus (an attractive face) and a positive response (“familiar”) accounts for this effect in the absence of any misattribution. In a face recognition task, participants were led to signal their sense of familiarity with previously seen and unseen faces by selecting either a pleasant (affectively congruent) or unpleasant (affectively incongruent) image. Consistent with the warm glow heuristic, higher false alarm rates were obtained for more attractive distracters, and this effect survived (and was, if anything, stronger) when an affectively incongruent response format was used. These findings are discussed in the context of current face memory and perceptual fluency models.     

The evaluative connotation of processing fluency: Inherently positive or moderated by motivational context?

A fundamental question for evaluation research is whether cues can impact evaluative responses directly or only in combination with contextual information. Focusing on the experience of processing fluency, the current work tested whether manipulating this cue’s motivational context would moderate its evaluative impact. Because fluently processed stimuli can be assumed to communicate safety, owing to implicit signals of either familiarity (through processes monitoring perception-memory coordination), we reasoned that motivation to avoid negative events should heighten preferences for fluently processed stimuli. Following a motivation manipulation, prevention-focused, but not promotion-focused, participants preferred stimuli that they were able to process quickly (Experiment 2) and that were preceded by concordant primes (Experiment 1). These findings suggest that the value of fluent processing reflects its relation to contextual features, such as one’s current motivational state.     

Language, Learning, and Color Perception

Abstract— People perceive colors categorically. But what is the role of the environment (or nurture)—specifically, language—in color perception? The effects of language on the way people categorize and perceive colors have been considered to be minimal, but recent evidence suggests that language may indeed change color perception. Speakers of languages with different color-name repertoires show differences in the way they perceive color. Research shows that categorical effects on color perception can be induced through laboratory training and suggests language can similarly change color perception through the mechanism of perceptual learning.

运动轨迹和方向对视觉空间关系加工的影响

视觉空间关系分为类别与数量两种表征。研究通过控制起参照作用的运动客体消失状态与定位客体出现时间,分析客体运动信息对两种关系判断的影响。结果发现:运动信息在各间隔时间对类别任务影响呈序列排列,运动方向较轨迹信息有优势,轨迹较法线信息有优势;数量表征仅在0ms间隔受运动方向促进,在其他间隔下,三种位置上的判断均无差异。结果表明运动客体类别表征比数量表征更持久;且相对类别表征,数量判断作为精确距离表征不易受运动方向和轨迹信息影响。     

背景图相关度与知觉流畅性对意义材料学习的影响

可取难度理论和不流畅理论认为不流畅加工可促进学习,认知负荷理论则认为知觉不流畅所激发的额外认知负荷可能阻碍学习。研究采用2（知觉流畅性：流畅,不流畅）×3（背景图相关度：相关背景图、无关背景图和空白背景）被试间实验设计,考察学习意义材料时认知负荷（通过插入的背景图控制）与知觉流畅性的相互作用。结果发现：（1）知觉流畅性的主效应显著,知觉流畅时的学习成绩显著高于知觉不流畅时的成绩;背景图相关度的主效应显著,相关背景图条件下的成绩显著高于空白背景和无关背景图。（2）知觉流畅性与背景图相关度的交互作用显著,在知觉流畅条件下,呈现相关背景图的得分显著高于空白背景和无关背景图,后二者无显著差异;知觉不流畅条件下,三者间无显著差异。研究结果表明,在知觉流畅的条件下插入相关背景图有利于意义材料的学习;该结果支持认知负荷理论。     

Swedish norms for word fluency tests: FAS, animals and verbs

Verbal fluency tests are useful measures of acquired language impairment and cognitive decline of various etiologies. The aim of this study was to provide normative data for the Swedish population on the three verbal fluency tests, FAS, Animals and Verbs. A group of 165 healthy participants ranging from 16 to 89 years of age were assessed with the verbal fluency tests and tests of level of intellectual functioning. The sample was stratified by education, age and gender. Level of education had a substantial influence on the performance on verbal fluency, most clearly so in FAS and Verbs. Intellectual level had a positive and significant correlation with all measures of word fluency. Moreover, there was an interaction between age and gender such that women aged between 30 and 64 years outperformed elderly men on FAS and Verbs. Guidelines for instructions and scoring in Swedish are given in the article.     

Limited information estimation and testing of discretized multivariate normal structural models

Discretized multivariate normal structural models are often estimated using multistage estimation procedures. The asymptotic properties of parameter estimates, standard errors, and tests of structural restrictions on thresholds and polychoric correlations are well known. It was not clear how to assess the overall discrepancy between the contingency table and the model for these estimators. It is shown that the overall discrepancy can be decomposed into a distributional discrepancy and a structural discrepancy. A test of the overall model specification is proposed, as well as a test of the distributional specification (i.e., discretized multivariate normality). Also, the small sample performance of overall, distributional, and structural tests, as well as of parameter estimates and standard errors is investigated under conditions of correct model specification and also under mild structural and/or distributional misspecification. It is found that relatively small samples are needed for parameter estimates, standard errors, and structural tests. Larger samples are needed for the distributional and overall tests. Furthermore, parameter estimates, standard errors, and structural tests are surprisingly robust to distributional misspecification.
