Abstract:
Older adults are at a significantly increased risk of being involved in motor vehicle accidents. Evidence reveals that visual processing speed decreases with age, which may impact driving. The Motor-Free Visual Perception Test- Third Edition (MVPT-3) is used as a pre-driving assessment and has an age-normed Response Time Index that measures visual processing speed. In 2015, a new version, the new Motor-Free Visual Perception Test- Fourth Edition (MVPT-4), was published. The new MVPT-4 does not yet demonstrate its utility in measuring visual processing speed. The purpose of this study was to explore if differences in visual processing speed between younger adults ages 20-35 years and older adults ages 70 years and older could be detected using the new MVPT-4. Results revealed a significant difference between older and younger adults’ time to complete the MVPT-4 (pKeywords:

Aim of the study is to examine the values of the three dimensional perception and collect information about that. Starting point is the observation of differences in two and three dimensional perception abilities of individuals having education in visual arts. It has been observed that some students, who have high level of competency in two dimensional perception, do not have the same competency in three dimensional perception. This is considered important since it creates two and three dimensional perceptions and differences of expression between them. We tried to emphasize the importance of the subject particularly in terms of visual arts education in the current visual age. The study is a document review. In this study we addressed the characteristics of the age we are living in, perception, visual perception, and two and three dimensional perception. We summarized the differences in visual perception and included three dimensional comprehension. By examining the related literature, we came to the conclusion that the two and three dimensional perception processes and their requirements are different. Keywords: sculpture, three dimensional perceptions, visual perception, visual age.

When observing art the viewer's understanding results from the interplay between the marks made on the surface by the artist and the viewer's perception and knowledge of it. Here we use a novel set of stimuli to dissociate the influences of the marks on the surface and the viewer's perceptual experience upon the manner in which the viewer inspects art. Our stimuli provide the opportunity to study situations in which (1) the same visual stimulus can give rise to two different perceptual experiences in the viewer, and (2) the visual stimuli differ but give rise to the same perceptual experience in the viewer. We find that oculomotor behaviour changes when the perceptual experience changes. Oculomotor behaviour also differs when the viewer's perceptual experience is the same but the visual stimulus is different. The methodology used and insights gained from this study offer a first step toward an experimental exploration of the relative influences of the artist's creation and viewer's perception when viewing art and also toward a better understanding of the principles of composition in portraiture.

The study of perception of visual images and the influence of counseling upon them has received little if any attention. This study was designed to investigate this uncharted area and to demonstrate the effects of counseling upon visual perception. The primary function of this investigation was to seek answers to the following questions. Is it possible for group counseling to have an effect on one's perception of visual stimuli? Will a counseling experience which produces a change in a person' behavior also cause that person to perceive visual images in a different way than he perceived them before counseling? In other words, does a concomitant relationship exist between visual perception and other forms of perception?

In this paper, we present a new dataset Perceptual Imagination: Question-Answering (Perceptual-IQ) to evaluate the visual systems' commonsense reasoning ability when confronted with perceptual changes. In our dataset, the machines are given a question that includes a perceptual change over an image and they have to predict human response to the change. Perceptual-IQ consists of 3.7K manually annotated QA pairs from 1.6K curated images and covers various types of perceptual changes. Through the evaluation of vision-language models with Perceptual-IQ, we identify the performance gap (~25%) with human performance.

Visual perception is an important source of information for a human. It is directly related to vision although this relation is commonly not quantified but qualitatively well described. This research aims to establish a human visual perception model to analyse the perception process and thereby quantify its properties. Recognizing the relation between vision and perception, which are deterministic and probabilistic in nature, respectively, a probabilistic theory for perception is developed. From the theoretical results, the perception is defined in mathematical terms and based on this a perception model is devised in virtual reality for the verification of the theory.
