According to some synesthetes' reports, their experience involves an emotional sensation in which a conflict between the photism and presented color of a stimulus may evoke a feeling of discomfort. In order to investigate the impact of this experience on performance, two experiments were carried out on two synesthetes and their matched control groups. Experiments were tailored for each synesthe...

The color-word Stroop is a popular measure in psychological assessments. Evidence suggests that Stroop performance relies heavily on reading, an ability that improves over childhood. One way to influence reading proficiency is by orthographic manipulations. To determine the degree of interference posed by orthographic manipulations with development, in addition to standard color-Words (purple) ...

For the past 50 years, language acquisition researchers have explored the fascinating question of “the language explosion”: how children are able to rapidly acquire hundreds to thousands of new words in a brief period of time. Focusing primarily on how basic-level nouns, such as “cup”, are quickly mapped to visible objects, researchers have proposed several constraints guiding early word learni...

In this paper, we describe a new scheme to color image segmentation which is based on supervised pixel classification methods. Using color pixel classification alone does not extract accurately enough color regions, so we suggest to use a strategy based on four steps in different color spaces: simplification, pixel classification, marker extraction and color watershed growing. The strategy is p...

Basic color terms were originally defined by Berlin and Kay based on linguistic definitions and refer to a subset of color expressions that are universal across languages. In this paper, we investigate and report that basic color terms demonstrate much stronger statistical characteristics that differentiate them from other color words. We introduce a probabilistic interpretation of color naming...

The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e., to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view, observers are unable to ignore irrelevant features of an attended object (Kahneman & Henik, 1981). In th...

The presence of irrelevant words (incongruent color and shape names) substantially slowed the sorting of shapes and colors. This interference was maintained over four sessions of practice for color sorting, but essentially vanished for shape classification and color classification using stimuli in which the word and color were physically separated. Interference with oral naming was maintained o...

Region growing-based color image segmentation approaches suffer from expensive computation cost. In order to overcome this issue, a novel region-based color image segmentation method based on P systems is proposed in this paper. A tissue-like P system is designed in such a way that an adaptive selection of target regions is achieved. The proposed method is evaluated on several real-life color i...
