This study introduces and examines the principle of accentuation as a novel mechanism in perceptual organization, analyzing its effects through framework Grossberg’s Adaptive Resonance Theory (ART). We demonstrate that localized accentuators, manifesting minimal dissimilarities or discontinuities, can significantly modulate global perceptions, inducing illusions geometric distortion, orientation shifts, apparent motion. Through series phenomenological experiments, we establish supersede...
Background: This study investigates the complex relationship between accentuation and attention in visual perception, extending classical Gestalt principles by introducing dissimilarity as a complementary mechanism to similarity perceptual organization. Objectives Methods: Through series of phenomenological experiments, we demonstrate how accentuation, driven dissimilarity, plays crucial role shaping experience guiding attention. Results: Our findings reveal that serves pre-attentive for...
Affective prosody, which conveys emotions such as anger and happiness through vocal tone, plays a significant role in communication verbal instructions. While emotional stimuli are known to capture attention, the influence of affective instructions on task performance remains underexplored. This study investigated effects prosody response time (RT) accuracy during manual joystick movement task. Forty-five Latvian-speaking participants responded indicating spatial directions (up, down, left,...
Abstract The extent to which languages share properties reflecting the non-linguistic constraints of speakers who speak them is key debate regarding relationship between language and cognition. A critical case spatial communication, where it has been argued that semantic universals should exist, if anywhere. Here, using an experimental paradigm able separate variation within a from languages, we tested use demonstratives—the most fundamental frequent terms across languages. In n = 874 29...
How a food, or dish, is named and how its components attributes are described can all influence the perception enjoyment of food. Therefore, tracing patterns in food descriptions determining their role be value. The aims this study were following: (1) to describe multisensory experience as represented microblog entries concerning drink on Twitter, (2) provide an overview changes above-mentioned representations during period 2011–20, (3) contribute broader understanding human–food...
The main purpose of this work is to explore the Gestalt principle similarity and demonstrate that use term alone not sufficient understand dynamics grouping fully correctly. More generally, aims show for a full understanding perceptual organization occurring both in classical mostly new phenomena here presented. Limits incompleteness have suggested basic, more general stronger role dissimilarity under large variety conditions. Dissimilarity was shown as basic figure-ground segregation, tool...
This study explores perceptual organisation and shape perception when viewing a tetragon an additional element (a dot) that is located at varying positions distances next to the tetragon. The aim of determine factors can alter interpretation object configuration impact whether presented perceived as diamond or square. Methods used in this are forced-choice task subjective measurement eye tracking objective processes. Overall, 31 stimuli were participants: two different sizes with inside...
Symmetry is an important geometric feature that affects object segmentation into parts, though De Winter and Wagemans note partly occluded objects can still be identified by the remaining visible parts. In two sets of experiments with children ( n = 31, age 7–11, M 8.8, SD 1.4) adults 19, 17–57, 30.4, 12.6), we used 13 basic figures distinguished symmetry types to test how they are naturally segmented or combined what developmental impacts on combination. first experiment, participants were...
Although human perception is geometrically constrained, not all geometric relations are equally prominent and used in everyday settings perception.Further, some systematically transformed.In this study we describe a robust framework expressing spatial but including strong systematic non-geometric extensions that operate perception.We generally adopt the view cognition centers on qualitative relations, geometrical topological also functional ones (Coventry Garrod, 2004, Gärdenfors, 2014, Mani...
Abstract Our paper provides a critical overview of the advantages, disadvantages, uncertainties, and challenges regarding AI application in medicine. Without denying importance medical applications, we are arguing for hybrid complementary view future systems where powerful resources integrated with human decision making.
Face perception is considered to be a canonical example of configurational visual processing. However, not all facial information equally important when reading expressions. The eyes and mouth seem crucial, but they have different roles significance. By varying the shape mouth, eyes, other factors, we conducted two experiments: first, examined eye movements depending on configurations types instructions (neutral emotionally valenced); second, used same stimuli in rating task. Our results...
The article investigates the relations, in light of new paradigms economic development, between trust and wealth at micro level Republic Latvia, by means a structural equation modelling-based approach framework combining social capital identity theory, rationale cross-fertilization cognitive science. Results are also tested against control dimensions reflecting relevant divides Latvian society (residence place dimensions; ethno-linguistic belongings; educational differences). General results...
This paper aims to describe how spatial semantic categories of containment and support are expressed in three languages, – Lithuanian, Latvian Estonian, which spoken the same area, though only first two them genealogically related. Our research is based on a production task (n = 60 for each language) consisting answers picture stimuli representing major subtypes support: full containment, partial interlocking support-from-below, adhesion, hanging encirclement with contact support. The...
Biological motion perception is a specific type of perceptual organization, during which clear image moving human body perceptually generated in virtue certain core light dots representing the major joint movements. While processes biological have been studied extensively for almost century, there still debate on whether task performance can be equally precise across all visual field or central specified perception. The current study explores and figure–ground segmentation peripheral field,...
With some overlapping and contradicting results a number of studies have demonstrated that there is an interrelation between colors emotions.Some conclude other aesthetic effects are strong emotion triggers inducing affective reaction when interacting with interfaces or webpages.Our study tests color-emotion mappings in interface environments within modified framework Ou et al. (2004a, b, c) applying rating task in-group quasiexperimental setting for selected from typical color scheme (MS...
Spatial proximity is not just a geometric attribute but co-determined by factors of scale (visual scope or navigational scale), object features, and specific interactional patterns between objects, to mention few.We conducted three experiments test the use natural language descriptors in Latvian (words representing different operators language).In repeated-measures quasi-experiment (Study 1, n=25, adults), we used rating task evaluate set functional stimuli (photographs everyday scenes) with...
Abstract Studies analysing biological motion perception based on reduced number of dots have demonstrated that can be perceived even when only the lower part body is visible or representing object reduced. What minimal amount information enables to distinguished from its scrambled version? The results current experiment demonstrate version formed approximately 5 (4.7 ± 0.1) dots. Additionally, we also investigated whether threshold value for differs in central and peripheral visual fields....
