“…It might also have to do with the mixed presentation of delays in the current study, given that Zuidhoek et al (2003) used a blocked presentation of delays. The fact that delay did not result in a significant deterioration of performance, shows that memory traces and maintenance strategies for haptic stimuli were still effective at 10 s retention intervals, comparable to other tactile studies showing retention up to at least 15 s (Kiphart et al 1992;Bowers et al 1990;Burton and Sinclair 2000;Woods et al 2004).…”

Research has shown that haptic spatial matching at intermanual distances over 60 cm is prone to large systematic errors. The error pattern has been explained by the use of reference frames intermediate between egocentric and allocentric coding. This study investigated haptic performance in near peripersonal space, i.e. at intermanual distances of 60 cm and less. Twelve blindfolded participants (six males and six females) were presented with two turn bars at equal distances from the midsagittal plane, 30 or 60 cm apart. Different orientations (vertical/horizontal or oblique) of the left bar had to be matched by adjusting the right bar to either a mirror symmetric (/ \) or parallel (/ /) position. The mirror symmetry task can in principle be performed accurately in both an egocentric and an allocentric reference frame, whereas the parallel task requires an allocentric representation. Results showed that parallel matching induced large systematic errors which increased with distance. Overall error was significantly smaller in the mirror task. The task difference also held for the vertical orientation at 60 cm distance, even though this orientation required the same response in both tasks, showing a marked effect of task instruction. In addition, men outperformed women on the parallel task. Finally, contrary to our expectations, systematic errors were found in the mirror task, predominantly at 30 cm distance. Based on these findings, we suggest that haptic performance in near peripersonal space might be dominated by different mechanisms than those which come into play at distances over 60 cm. Moreover, our results indicate that both inter-individual differences and task demands affect task performance in haptic spatial matching. Therefore, we conclude that the study of haptic spatial matching in near peripersonal space might reveal important additional constraints for the specification of adequate models of haptic spatial performance.

“…Conversely, Klatzky, Lederman, and Metzger (1985) have argued that the identification of objects by touch involves an "expert" system, and Kiphart, Auday, and Cross (1988), in a series of studies, failed to find convincing evidence for an STM decay function even though they used a broad range of delay intervals and stimuli judged to be relatively complex. More recently, Bowers, Mollenhauer, and Luxford (1990) failed in their attempt to observe an STM decay function in a shared-attention recall task. However, in this latest study the range of intervals explored was somewhat narrow, that is, 5, 10, and 20 sec, and the shapes were simple and geometrical.…”

College students actively felt complex objects for 3 sec, and, after delay intervals of 5, 15, 30, or 45 sec, they received either the same object or a different object for comparison. In a signal detection framework, it was observed that d' scores were significantly higher for the 5-and 15sec intervals than for the 30-and 45-sec intervals. Although a clearly negatively accelerated function was not obtained, this is one of the rare instances in which any decay function has been observed for haptic memory. Although it seems counterintuitive that the entire short-term-memory decay function occupies the narrow band extending from 15 to 30 sec, it is clear from previous studies that short-term haptic memory is unique. Results were discussed in terms of findings in both active-and passive-touch experiments.Invited speakers will include Graham Hitch, Asher Koriat, Michael Pressley, and Wolfgang Schneider.
