“…A limitation of the present study concerns the measurement of the RTs, highlighting the need for the future studies that measure RTs and disentangle different phases of task performance such as perceiving the haptic stimuli, performing a mental operation, and locating this information physically onto the referent space (cf. Szubielska and Bałaj 2018). Secondly, we did not assess particular exploration strategies.…”

The current study investigated adults’ spatial-scaling abilities using a haptic localization task. As a first aim, we examined the strategies used to solve this haptic task. Secondly, we explored whether irrelevant visual information influenced adults’ spatial-scaling performance. Thirty-two adults were asked to locate targets as presented in maps on a larger or same-sized referent space. Maps varied in size in accordance with different scaling factors (1:4, 1:2, 1:1), whereas the referent space was constant in size throughout the experimental session. The availability of irrelevant, non-informative vision was manipulated by blindfolding half of the participants prior to the experiment (condition without non-informative vision), whereas the other half were able to see their surroundings with the stimuli being hidden behind a curtain (condition with non-informative vision). Analyses with absolute errors (after correcting for reversal errors) as the dependent variable revealed a significant interaction of the scaling factor and non-informative vision condition. Adults in the blindfolded condition showed constant errors and response times irrespective of scaling factor. Such a response pattern indicates the usage of relative strategies. Adults in the curtain condition showed a linear increase in errors with higher scaling factors, whereas their response times remained constant. This pattern of results supports the usage of absolute strategies or mental transformation strategies. Overall, our results indicate different scaling strategies depending on the availability of non-informative vision, highlighting the strong influence of (even irrelevant) vision on adults’ haptic processing.

“…This study shows that canonical size can be disclosed both in the visual and tactile domain-which supports the conclusions about there being similarities in information processing for both visual and tactile size (cf. Craddock & Lawson, 2009a, 2009bSmith et al, 2005;Szubielska, 2015;Szubielska & Bałaj, 2018), but it does not settle whether physical size information is represented both visually and tactilely. It is possible that in a tactile condition, participants used visual images and visualized drawings on sheets before they made them with the perceptual haptic feedback.…”

“…An increasing amount of research shows similarities between visual and haptic spatial processing (for an overview, see Lacey & Sathian, 2014) which also applies to the size of objects. The accuracy of estimating the size of objects perceived by sight and by touch does not differ, especially when adults estimate the magnitude manually (Smith et al, 2005;Szubielska & Bałaj, 2018). In sighted individuals both haptic and visual recognition are size-dependent (Craddock & Lawson, 2009a, 2009bSzubielska, 2015).…”

“…In the current study, we asked whether, similarly to the visual domain (Konkle & Oliva, 2011), adults use canonical size in the tactile domain-when producing embossed drawings of familiar objects from memory. As there are similarities between visual and tactile processing of spatial features of objects (e.g., Lacey & Sathian, 2014, Smith et al, 2005Szubielska & Bałaj, 2018) we expected that the canonical size effect reveals both in visual domain and in tactile drawings. Participants were asked to draw objects of various real-life sizes in two different conditions-using eyesight, on ordinary sheets of paper and, when blindfolded, using touch, on special foils designed for use by blind individuals to create drawings (the foil becomes convex in the place where the lines are made).…”

“…In sighted individuals both haptic and visual recognition are size-dependent (Craddock & Lawson, 2009a, 2009bSzubielska, 2015). In both a tactile domain and a visual domain, enlarging and reducing the size of objects in the mind increases the response time in imagery scaling task, which is a linear function of increasing the change of scale (Szubielska & Bałaj, 2018;Szubielska & Möhring, 2019).…”

To date canonical size for physical objects has been exclusively investigated in the visual domain and termed canonical visual size. As the visual and haptic modalities are interconnected in object processing, we have investigated if canonical size occurs in the tactile domain, namely, in embossed drawings made by sighted adults when blindfolded. 17 participants were asked to draw 16 objects of 8 different ranks of physical size. In the visual domain, they drew on sheets of paper, and in the tactile domain, they drew (when blindfolded) on special plastic sheets for embossed graphics haptically controlling the performance with hands. In both the visual and the tactile domain the size of drawings increased linearly with the logarithm of the physical size of real-world objects indicating occurrence of canonical size effect in both domains. Our findings demonstrated that canonical size is not only visual in character but that it is also revealed in a haptic drawing task. It suggests that spatial images (at least visual and tactile) are shared instead of being unimodal in nature.

The present study examined differences in adults’ spatial-scaling abilities across three perceptual conditions: (1) visual, (2) haptic, and (3) visual and haptic. Participants were instructed to encode the position of a convex target presented in a simple map without a time limit. Immediately after encoding the map, participants were presented with a referent space and asked to place a disc at the same location from memory. All spaces were designed as tactile graphics. Positions of targets varied along the horizontal dimension. The referent space was constant in size while sizes of maps were systematically varied, resulting in three scaling factor conditions: 1:4, 1:2, 1:1. Sixty adults participated in the study (M = 21.18; SD = 1.05). One-third of them was blindfolded throughout the entire experiment (haptic condition). The second group of participants was allowed to see the graphics (visual condition); the third group were instructed to see and touch the graphics (bimodal condition). An analysis of participants’ absolute errors showed that participants produced larger errors in the haptic condition as opposed to the visual and bimodal conditions. There was also a significant interaction effect between scaling factor and perceptual condition. In the visual and bimodal conditions, results showed a linear increase in errors with higher scaling factors (which may suggest that adults adopted mental transformation strategies during the spatial scaling process), whereas, in the haptic condition, this relation was quadratic. Findings imply that adults’ spatial-scaling performance decreases when visual information is not available.
