What is the role of motor simulation in action and object recognition? Evidence from apraxia

Abstract: An important issue in contemporary cognitive neuroscience concerns the role of motor production processes in perceptual and conceptual analysis. To address this issue, we studied the performance of a large group of unilateral stroke patients across a range of tasks using the same set of common manipulable objects. All patients (n = 37) were tested for their ability to demonstrate the use of the objects, recognize the objects, recognize the corresponding object-associated pantomimes, and imitate those same pant… Show more

“…It also is in line with the results from neuropsychological studies showing that damage to various parts of the motor system such as the basal ganglia (43,44), the inferior parietal lobe (43)(44)(45), the inferior frontal gyrus (43,45,46), the left premotor cortex (43,45), the primary motor cortex (43,45), and the bilateral superior parietal lobule (46) cause motor or praxis disorders (a disorder affecting the capacity to perform actions despite preserved basic motor and somatosensory functions) but do not necessarily hamper action identification.…”

“…An association of deficits in imitation and recognition of gestures has been observed at a group level by Negri et al (2007;r ¼ 0.59, p ¼ 0.001), while Tessari et al (2007) found only a trend (r ¼ 0.32, p ¼ 0.07). At variance with the group-level pattern, in the study by Negri et al (2007), patient P.T. was found to be impaired at imitating meaningful (object-associated and intransitive actions) as well as meaningless gestures, but he was able to recognize object-associated pantomimes.…”

“…A visual gesture can be imitated using a semantic or a non-semantic route. In addition to the visual analysis, the semantic route encompasses the input praxicon that allows the recognition of a familiar gesture, the semantic or conceptual system, that stores its content, and the output praxicon that permits to produce it (in Negri et al (2007), praxicons are referred to as axemes). The non-semantic route is necessary for imitating novel gestures, in the same way that the sublexical mechanism of language production models is necessary for reading novel, regular words and non-words.…”

“…Adolescents with congenital motor disorders recognize biological motion in spite of never having experienced it in their own actions and thus not having any relevant actions to simulate (Pavlova et al 2003). Studies of apraxia, in which patients no longer know how to perform the correct actions to use with various objects, nevertheless recognize the objects and the correct actions carried out on them by others (Hodges et al 1999;Negri et al 2007). …”
