“…The lack of correlation in our study is rather in keeping with the double dissociations between tools use and tool-noun comprehension that we observed at individual level. These findings also agree with other studies that described selective deficits affecting one of these abilities at a time (De Renzi & Lucchelli, 1988;Negri et al, 2007;Rosci, Valentina, Laiacona, & Capitani, 2003;Rumiati et al, 2001) and suggest that the ability to use tools is not necessary for a successful comprehension of their nouns.…”

“…This is in line with a number of lesion studies showing that action recognition and execution are subserved by different brain regions Rosci et al, 2003), and lesions to the left motor and premotor areas do not necessarily impact the accuracy in the comprehension of words associated with hand actions (Arévalo, Baldo, & Dronkers, 2010). Based on these findings, it seems unlikely that sensorimotor regions host the representations of action concepts or the lexical definition of those categories.…”

It has been proposed that language and action representational systems overlap when the tasks used to assess them involve the same stimuli and require abilities acquired at similarly early developmental stage. We matched variables at task and stimulus level to test this hypothesis in a group of 12 left-damaged patients (and 17 controls). At the patients' group level, we replicated previously reported correlations between linguistic and nonlinguistic tasks. When performances were analysed individually, however, double dissociations were observed between the ability to imitate pantomimes and the ability to produce and comprehend the corresponding action verbs, as well as between the ability to use tools and the ability to comprehend the corresponding tool nouns. These findings suggest that processing action words is independent of the ability to produce the associated object-directed actions. Double dissociations were also found between the ability to comprehend action verbs and the ability to comprehend tool nouns. Moreover, action and tool naming showed differential effects of age of acquisition, suggesting that the two word categories meet the lexical organization by word class (nouns and verbs), even when related to identical action concept. Dissociations at behavioural level are supported by anatomical dissociations shown in the analysis of patients' lesions.

“…IA is not simply a more severe form of IMA as some sceptics argued (Sittig 1931;Zangwill 1960), as demonstrated by reports of patients with impaired imitation but normal object and tool use and vice versa (e.g. De Renzi & Lucchelli 1988;Rosci et al 2003). Recently, Goldenberg (2009) proposed that, in the case of imitation, the system needs to understand the spatial relationships between body parts, while in tool/object use, it needs to understand the spatial relationships between the hand and the tool or between tools and objects.…”

Cognitive neuroscientists have contributed to the understanding of imitation according to their expertise. Neuropsychologists first established over a century ago that lesions to the left hemisphere of right-handed individuals lead to a dramatic reduction of their ability to imitate gestures. In contrast, after frontal lobe damage, patients may experience severe difficulties in inhibiting their imitative tendency. These findings suggested that our tendency to imitate is mostly sustained by the left hemisphere and that we normally manage successfully to keep it under control. Neuropsychologists went on investigating other aspects of gesture imitation. These include the existence of putative mechanisms involved in imitating different types of gestures (e.g. meaningful and meaningless or transitive and intransitive), the strategic control over these mechanisms and whether there are differences in imitation depending on the action goal or the body part used. Based on neuropsychological findings, some cognitive models of gesture imitation have been forwarded, the most influential of which will be reviewed here. In particular, reference will be made to the dual route model and to accounts that associate the imitative deficit to putative degraded body representations.

“…Contrary to this hypothesis is the performance of apraxic patients who are not impaired for conceptual knowledge of graspable objects. There are a number of such patients (Buxbaum & Saffran, 2002;Buxbaum, Sirigu, Schwartz, & Klatzky, 2003;Buxbaum, Veramonti, & Schwartz, 2000;Cubelli et al, 2000;Halsband et al, 2001;Hodges, Spatt, & Patterson, 1999;Montomura & Yamadori, 1994;Moreaud, Charnallet, & Pellat, 1998;Ochipa et al, 1989;Rapcsak et al, 1995;Rosci, Valentina, Laiacona, & Capitani, 2003;Rumiati et al, 2001; for review, see Johnson-Frey, 2004; for discussion, see Dumont, Ska, & Joanette, 2000;Hodges, Bozeat, Lambon Ralph, Patterson, & Spatt, 2000;Mahon & Caramazza, 2003). For instance, Rosci and colleagues (2003) designed a study to specifically investigate the issue of whether impairments for object use are related to deficits in conceptual knowledge of manipulable objects.…”

Research over the last several decades has led to clear and empirically tractable proposals about the representation of conceptual knowledge in the brain. Here we argue that there are already sufficient data from neuropsychology to strongly constrain extant hypotheses about the representation of conceptual knowledge. One constraint imposed by these neuropsychological data is that recognition of actions and understanding of objects do not necessarily depend on the ability to produce object-associated actions. This conclusion compels a reconsideration of the role played by motor planning and/or execution processes in action and object recognition and understanding.
