“…At the moment, it seems that object recognition is sensitive to surface property information but receives no particular benefit from it (unless the property is diagnostic, as discussed below). However, work with Alzheimer’s patients has shown that color information can improve visual recognition, at least in the short‐term (Cernin et al. , 2003), suggesting that benefits may accrue in development and aging.…”

Object recognition studies have almost exclusively involved vision, focusing on shape rather than surface properties such as color. Visual object representations are thought to integrate shape and color information because changing the color of studied objects impairs their subsequent recognition. However, little is known about integration of surface properties into visuo-haptic multisensory representations. Here, participants studied objects with distinct patterns of surface properties (color in Experiment 1, texture in Experiments 2 & 3) and had to discriminate between object shapes when color/texture schemes were altered in within-modal (visual and haptic) and cross-modal (visual study/haptic test and vice versa) conditions. In Experiment 1, color changes impaired within-modal visual recognition but had no effect on cross-modal recognition, suggesting that the multisensory representation is not influenced by modality-specific surface properties. In Experiment 2, texture changes impaired recognition in all conditions, suggesting that both unisensory and multisensory representations integrate modality-independent surface properties. However, the cross-modal impairment might have reflected either the texture change or a failure to form the multisensory representation. Experiment 3 attempted to distinguish between these possibilities by combining changes in texture with changes in orientation, taking advantage of the known view-independence of the multisensory representation, but the results were not conclusive owing to the overwhelming effect of texture change. The simplest account is that the multisensory representation integrates shape and modality-independent surface properties. However, more work is required to investigate this and the conditions under which multisensory integration of structural and surface properties occurs.

“…Older adults often have decreased visual acuity and contrast sensitivity (Faubert, 2002). Normally aging adults and those with dementia may benefit from the use of color in recognizing objects, perhaps due to these decreased visual abilities (Cernin, Keller, & Stoner, 2003;Wijk et al, 2002;Wurm, Legge, Isenberg, & Luebker, 1993). Color can improve the cue's degree of contrast with the environment and give additional sensory information about the cue.…”

Working Memory, Cues, and Wayfinding in Older Women

Individuals create cognitive maps based on relationships between cues in the environment. Older individuals are often impaired in wayfinding, especially in environments that lack distinctive features. This study examines how working memory ability in older women is related to wayfinding performance in the presence of salient (distinctive, prominent) or nonsalient cues. The degree of salient cue complexity is also examined, thus leading to the hypothesis that salient, complex cues are important in wayfinding and that working memory capacity is related to wayfinding performance. The virtual computer-generated arena is used to test this hypothesis in 20 healthy older women in three different environmental cue conditions varying in salience and complexity. Data analyses indicate that older women perform best in salient cue conditions. A greater working memory capacity is related to improved performance in the nonsalient cue condition. These findings offer preliminary evidence that cue salience is especially important in wayfinding.

“…According to experimental research, the presence of color "cues" significantly improves the performance of a variety of tasks related to memorization [40; 79; 88], even with cognitive impairments [33]. With color cues, people of the old (65-74 years old) and great (over 75 years old) age best remember the area in virtual simulations [37].…”

The purpose of the article is to present an analysis of the studies existing in domestic and foreign science of the necessary age-related "correction" of the color of the educational environment for older people, carried out in respect of the fact that chromatic communication is not limited exclusively to biological reactions, but its structure, in addition to perceptual one, includes much more significant psychological mechanisms and semiotic levels. The selection of research sources was carried out through the RSCI, Google Scholar, Scopus, and Web of Science systems. In total, 63 full texts of articles published between 1999 and 2019 were analyzed. In the process of work, the methods of theoretical and comparative analysis, systematization and generalization of the material were used. The analysis made it possible to distinguish three groups of research. The first group includes works that present the physiological prerequisites for the necessary changes in the chromatic design of the educational space intended for older people. The second group of studies analyzes various aspects of the impact of the color of the educational environment on older people in a psychological connotation. The third group involves the socio-cultural aspects of the formation of the educational environment for older people and analyzes this phenomenon in terms of connection with the lifestyle, way of thinking, physical and emotional-intellectual activity, and social conditions of the aging person. The results of the study convince that color correction in an educational environment designed for older people can cause noticeable changes in the quality of learning at several levels at once – biological (increasing the availability of information and significantly reducing physiological barriers to perception), psychological (supporting and strengthening the processes of memorization and information processing, increasing the psychological comfort of the educational environment), and social (improving the quality of life of older people).
