Culture and odor categorization : agreement between cultures depends upon the odors
2003
This study evaluated the effect of culture on the relationship between psychological dimensions underlying odor perception and odor categorization. In a first experiment, French, Vietnamese and American participants rated several perceptual dimensions of everyday odorants, and sorted these odorants on the basis of their similarity. Results showed that the three groups of participants differed in their perceptual judgments but agreed in categorizing the odors into four consensual groups (floral, sweet, bad, and nature). Three dimensions––pleasantness, edibility, cosmetic acceptability––discriminated these groups in the same way in the three countries. In a second experiment, the participants…
Graphemic complexity and multiple print-to-sound associations in visual word recognition
2005
Max Planck Institute for Psycholinguistics, Nijmegen, The Netherlands It has recently been reported that words containing a multiletter grapheme are processed slower than are words composed of single-letter graphemes (Rastle & Coltheart, 1998; Rey, Jacobs, Schmidt-Weigand, & Ziegler, 1998). In the present study, using a perceptual identification task, we found in Experiment 1 that this graphemic complexity effect can be observed while controlling for multiple print-to-sound associations, indexed by regularity or consistency. In Experiment 2, we obtained cumulative effects of graphemic complexity and regularity. These effects were replicated in Experiment 3 in a naming task. Overall, these r…
Wine Quality Perception: A Sensory Point of View
2016
Wine is a complex product, which had moved from a nutritional food to a hedonic beverage in consumer representation. This fact has increased the demand of quality products in the market. In this context, it is of high interest for wine producers to understand the underlying indicators of consumers’ quality perception as well as the relative importance they attach to these cues when inferring quality in wine to reach the alignment of consumers’ expectations, needs and wants. This chapter is aimed at giving an overview of the current state of knowledge of the indicators of wine quality perception from a sensory point of view. For this purpose, the factors driving perceived quality of wine as …
Perception of mineral character in Sauvignon blanc wine: inter-individual differences
2014
Revue non indexée dans le JCR.; Of the descriptors employed to characterize wine organoleptically, minerality is arguably one of the most enigmatic. The aim of the work described in this article was to delineate the nature of perceived minerality in Sauvignon wine, specifically its sensorial reality for experienced wine professionals from France and New Zealand. Participants evaluated 16 Sauvignon blanc wines (8 French; 8 New Zealand) under three conditions, ortho-nasal olfaction, palate only (Nose-clip condition), and by full tasting (global perception). Data from the global condition only are reported here. Key results include: i) that although there were quantitative differences in perce…
Ambiente comunitario y actitud hacia la autoridad: relaciones con la calidad de las relaciones familiares y con la agresión hacia los iguales en adol…
2014
El objetivo del presente estudio es explorar las relaciones entre la calidad de las relaciones familiares, la percepción del ambiente comunita-rio y la actitud de los adolescentes hacia la autoridad (policía, profesores) y normas sociales, en la predicción del bienestar subjetivo y un problema conductual de actualidad como es la agresión hacia los iguales. Para poner a prueba estas relaciones múltiples se ha utilizado una muestra de 554 adoles-centes de ambos sexos con edades comprendidas entre los 12 y los 16 años. Los datos se recogieron en dos tiempos con un intervalo temporal de 6 me-ses y se analizaron mediante el cálculo de modelos de ecuaciones estructu-rales, incluyendo un análisis …
“Red wins”, “black wins” and “blue loses” effects are in the eye of beholder, but they are culturally universal: A cross-cultural analysis of the inf…
2014
Abstract Although many studies have demonstrated an influence of uniform colors on sports performance, there are still more questions than answers regarding this issue. In our study, participants from Poland (N = 147) and China (N = 143) watched a two-minute video of a semi-professional boxing match. The participants viewed six different versions of the same fight - the original was modified to change the colors of the boxers’ trunks (red vs. blue, blue vs. red, blue vs. black, black vs. blue, red vs. black, and black vs. red). We experimentally confirmed that “black wins” and “red wins” effects exist, but in a way that caused an erroneous perception of the number of blows landed by boxers …
Reclaiming the Stroop Effect Back From Control to Input-Driven Attention and Perception
2019
According to a growing consensus, the Stroop effect is understood as a phenomenon of conflict and cognitive control. A tidal wave of recent research alleges that incongruent Stroop stimuli generate conflict, which is then managed and resolved by top-down cognitive control. We argue otherwise: control studies fail to account for major Stroop results obtained over a century-long history of research. We list some of the most compelling developments and show that no control account can serve as a viable explanation for major Stroop phenomena and that there exist more parsimonious explanations for other Stroop related phenomena. Against a wealth of studies and emerging consensus, we posit that d…
Perceived Social Support, School Engagement and Satisfaction with School
2017
Abstract There is evidence that social support from families, peers and teachers has an influence on student engagement, academic success, and satisfaction with school. The aim of this work is to use structural equations to analyze the effects of the perceived academic support and the school engagement on the satisfaction with school. A battery of measurement tools was administered to 2028 Angolan students aged between 14 and 22 years (mean = 17.4; SD = 2.3). The results show the influence of the perceived academic support of teachers, family, and peers on the satisfaction with school using the school engagement as mediating variable. The perception of peer support does not show a predicti…
How Comprehensive School Students Perceive their Psychosocial School Environment
2010
The aim of this study was to describe students’ perceptions of their psychosocial school environment and to examine the associations between such perceptions and students’ perceived school performance. Our analyses were based on data from the Health Behaviour in School‐Aged Children 2006 study, involving responses by Finnish students from grades 7 and 9. The results indicated that students’ perceptions of their school environment were fairly positive, but that a remarkably large proportion of the students reported negative attitudes towards school. School engagement, school strain, and teacher‐student relations were found to be the most influential predictors in the psychosocial school envi…
Students' Perception of School and Their Smoking and Alcohol Use: A Cross-National Study
2000
The objective of the paper is to study how 15 year old students' perceptions of the psychosocial environment in their schools, defined as student autonomy, teacher support, student support and demands, relate to smoking and alcohol use. Data from 15 year old students in Finland and Norway are included (n=2.816), using structural equation modelling to test theoretical models. The best model fitting the data shows that low student autonomy, low teacher support, student support and inadequate demands are significantly associated with health compromising behaviours directly, and indirectly through students' satisfaction with school. Low student autonomy is the strongest predictor of the four. T…
