“…We have previously demonstrated that broadly similar costs of generalizing across orientation changes in depth exist in haptic and visual object recognition (Craddock & Lawson, 2008;Lawson, in press). Experiment 2 revealed that haptic size-change costs are of the same order of magnitude as haptic orientation-change costs.…”

Two experiments examined the effects of size changes on haptic object recognition. In Experiment 1, participants named one of three exemplars (a standard-size-and-shape, different-size, or different-shape exemplar) of 36 categories of real, familiar objects. They then performed an old/new recognition task on the basis of object identity for the standard exemplars of all 36 objects. Half of the participants performed both blocks visually; the other half performed both blocks haptically. The participants were able to efficiently name unusually sized objects haptically, consistent with previous findings of good recognition of small-scale models of stimuli (Lawson, in press). However, performance was impaired for both visual and haptic old/new recognition when objects changed size or shape between blocks. In Experiment 2, participants performed a short-term haptic shapematching task using 3-D plastic models of familiar objects, and as in Experiment 1, a cost emerged for ignoring the irrelevant size change. Like its visual counterpart, haptic object recognition incurs a significant but modest cost for generalizing across size changes.

“…Previous research has shown that haptic object recognition suffers when there is a task-irrelevant change of object orientation between study and subsequent recognition (Craddock & Lawson, 2008;Lacey et al, 2007;Lawson, 2009;Newell et al, 2001), similar to the orientation sensitivity observed in visual object recognition (e.g., Lawson, 1999;Tarr & Cheng, 2003). Furthermore, several studies have demonstrated that visual orientation sensitivity generally declines with increasing ISIs (Ellis & Allport, 1986;Ellis, Allport, Humphreys, & Collis, 1989;Humphrey & Lupker, 1993;Lawson & Humphreys, 1996).…”

“…We reported a same-orientation benefit in a haptic old-new recognition task across delays of around 15 min (Craddock & Lawson, 2008) and at short intervals of about 5 sec in a sequential-matching task (Lawson, 2009). However, we are not aware of any studies that have compared orientation sensitivity across different delays.…”

“…There is substantial overlap in the neural architecture invoked during visual and haptic object exploration (e.g., Amedi, Jacobson, Hendler, Malach, & Zohary, 2002;Amedi, Malach, Hendler, Peled, & Zohary, 2001;Miquée et al, 2008), and visual and haptic object recognition are similarly impaired by changes in object orientation (Craddock & Lawson, 2008;Lacey, Peters, & Sathian, 2007;Lawson, 1999Lawson, , 2009Newell, Ernst, Tjan, & Bülthoff, 2001) and object size (Craddock & Lawson, 2009a, 2009b.…”

“…Although haptic object recognition is reasonably fast (e.g., Craddock & Lawson, 2008, 2009aKlatzky, Lederman, & Metzger, 1985), it is generally slower than vision (e.g., Craddock & Lawson, 2009a). Haptics relies on slower, more sequential exploration than does vision and must, therefore, depend more on working and shortt term memory to maintain and integrate information as it accumulates.…”
