Abstract

This study was conducted to investigate the psychological characteristics of the Luria hand test (LHT), a well-known neuropsychological assessment. We investigated the role of inner speech in LHT using the dual-task paradigm. Additionally, we investigated the relation between LHT and Wechsler Memory Scale—Revised (WMS-R) scores. Performance of the 21 university student participants on the LHT decreased significantly in the articulatory suppression condition, but not in spatial suppression. This result indicates that the inner speech or phonological loop of working memory plays an important role in the LHT. Moreover, only the verbal memory score of the WMS-R was correlated significantly with LHT performance. Based on these results, psychological characteristics of the LHT were discussed.

Highlights

The Luria hand test (LHT; Luria, 1966) is a well-known neurological assessment developed originally by AR Luria, a distinguished neuropsychologist influenced by the theory of LS Vygotsky
Post-hoc analysis revealed that the score of the articulatory suppression condition (M = 6.76, SD = 2.72)
As described in the Introduction, the LHT has been regarded as a non-verbal test of serial recall (Japanese Kaufman Assessment Battery for Children-2 (KABC-2) Publication Committee, 2013; Weiner et al, 2011)
