Colour perception changes with basic colour word comprehension

Recent work has investigated the origin of infant colour categories, showing pre-linguistic infants categorise colour even in the absence of colour words. These infant categories are similar but not identical to adult categories, giving rise to an important question about how infant colour perception changes with the learning of colour words. Here we present two novel paradigms in which 12- and 19-month-old participants learning English as their first language were assessed on their perception of colour, while data on their colour word comprehension were also collected. Results indicate that participants' perception of colours close to the colour category boundaries dramatically change after colour word learning. The results highlight the shift made from infant colour categories to adult-like linguistically mediated colour categories that accompanies colour word learning.

Research Highlights

• We aimed to test whether colour perception is linguistically mediated in infants.
• We used novel eye-tracking and pupillometry paradigms to test infant colour perception either side of learning colour words.
• Infants' discrimination of colour changes after learning colour words, suggesting a shift due to colour word learning.
• A shift from pre-linguistic colour representation to linguistically mediated colour representation is discussed.

     

Difficult name,cold man: Chinese names,gender stereotypicality and trustworthiness

Names can play an important role in forming first impressions. While much of the literature has demonstrated how alphabet-based names influence impression formation, little is known about how character-based names (e.g., Chinese names) affect interpersonal trust. Across six studies, we demonstrated that a difficult-to-recognise Chinese name with less frequently used characters activated masculine perception, which in turn decreased trust in the name holder. The masculine inferences from difficult names were replicated across within-subjects (Study 1a and 1b) and between-subjects judgements and maintained irrespective of normative knowledge about difficult names as male names (Study 1c). The mediation of gender stereotypicality was manifested in both measured spontaneous gender inference (Study 2a and Study 2b) and manipulated gender information (Study 2c). The effects of recognisability on masculine and trust perceptions were independent of pronunciationability (Study 2b). This research extends previous research by revealing the implications of character-based names and pictographic language on the feeling-as-information theory, also in terms of interpersonal contexts.     

编码和检索阶段的异质情境流畅性对再认的影响

研究采用经典的R/K范式，通过两个实验分别探讨编码阶段和检索阶段的异质情境流畅性对再认的影响。实验1为2（异质情境：高流畅性预期情境和低流畅性预期情境）×2（测试词类型：目标词和分心词）的混合实验设计，异质情境发生在编码阶段；实验2与实验1设计相同，不同之处在于异质情境发生在检索阶段。结果发现：异质情境发生在检索阶段时只对K反应产生影响，目标词在高流畅性情境中比低流畅性情境中的K反应率更高，而分心词在低流畅性情境中比高流畅性情境中的K反应率更高。研究表明，检索阶段的异质情境流畅性只影响熟悉性再认，支持双系统加工理论。     

A new goodness-of-fit measure for probit models: Surrogate R2

Probit models are used extensively for inferential purposes in the social sciences as discrete data are prevalent in a vast body of social studies. Among many accompanying model inference problems, a critical question remains unsettled: how to develop a goodness-of-fit measure that resembles the ordinary least square (OLS) R² used for linear models. Such a measure has long been sought to achieve ‘comparability’ of different empirical models across multiple samples addressing similar social questions. To this end, we propose a novel R² measure for probit models using the notion of surrogacy – simulating a continuous variable $S$ as a surrogate of the original discrete response (Liu & Zhang, Journal of the American Statistical Association, 113, 845 and 2018). The proposed R² is the proportion of the variance of the surrogate response explained by explanatory variables through a linear model, and we call it a surrogate R². This paper shows both theoretically and numerically that the surrogate R² approximates the OLS R² based on the latent continuous variable, preserves the interpretation of explained variation, and maintains monotonicity between nested models. As no other pseudo R², McKelvey and Zavoina's and McFadden's included, can meet all the three criteria simultaneously, our measure fills this crucial void in probit model inference.     

X good things in life: Processing fluency effects in the “Three good things in life” exercise

The present study examined whether difficulty of recollection may influence the effectiveness of the “Three good things in life” exercise that has previously been shown to increase happiness. Participants were randomly assigned to write 1–10 good things that happened to them during the day in the course of two weeks. We measured life satisfaction, positive and negative affect before the exercise and three times after the exercise. We found no effect of the number of good things participants wrote each day. Life satisfaction and positive affect of participants did not increase after the two weeks of the exercise, but we found a reduction in negative affect. We further investigated various aspects of the exercise in exploratory analyses.     

Perceptual fluency effects in judgments of creativity and beauty: creative objects are perceived fluently yet they are visually complex

ABSTRACT

Perceptual fluency typically has a positive influence on aesthetic evaluations of beauty, but few studies have examined its influence on creativity evaluations. Creativity has two facets, originality and quality. If creativity judgments involve estimating product originality, such judgments may be associated with perceptual disfluency, while product quality may be associated with perceptual fluency. We examined the relationship between perceptual fluency and judgments of creativity and beauty across seven experiments. Creativity judgments were affected by most perceptual fluencysources. We observed a highly-fluent-is-beautiful-and-creative relation when testing repeated exposure and figure-ground contrast. Prototypicality displayed a high-fluency–is-beautiful relation, with creativity judgments unaffected. Visual complexity displayed a consistent disfluent-is-creative effect, with mixed results for beauty. For creativity (but not beauty) evaluations, increased saliency of visual complexity led to discounting fluent-is-creative effects, supporting the hypothesis that there are at least two fluency pathways to creativity judgments that take both originality and quality into account.     

How to separate coordinate and categorical spatial relation components in integrated spatial representations: A new methodology for analysing sketch maps

Spatial relations between landmarks can be represented by means of categories and coordinates. In the present research, this paradigm was applied to sketch maps based on information acquired in goal-directed behaviour of exploration of a university campus area. The first aim was to investigate whether categorical and coordinate information can be considered conceptually independent in sketch maps. The second aim was to assess which kind of distance measure served better to represent coordinate information in the present case study, and finally to assess the factorial structure of coordinate and categorical data. Analytic methodology as well as statistical analysis were found to confirm that separating coordinate and categorical components was formally as well as empirically appropriate. A series of confirmatory factor analyses showed the best fit for the model with two correlated components, as well as an acceptable reliability of measures emerged. The two components were moderately correlated. Moreover, the adoption of Manhattan distance seemed to be the most effective method to represent coordinate spatial relations in spatial sketch maps of areas acquired through navigation.
