“…Moreover, the level of processing effect was significant in stem completion, but failed to reach significance in word identification. Similar results-that is, larger priming effects after semantic than physical processing-have been reported by Carlesimo, Marfia, Loasses, and Caltagirone (1996) and Hamman & Squire (1996). Jenkins, Russo, and Parkin (1998) used a word fragment completion test to investigate two amnesic groups, a group of Korsakoff patients and a group with closed head injury.…”

In this paper we examine the impact of amnesia and of levels of processing on implicit memory by using a well-established fragmented picture-naming test with proven adequate reliability. A group of patients with amnesia of non-Korsakoff etiology was compared to a control group. While amnesic patients showed a deficit in perceptual priming, both groups showed a comparable level of processing effect. Our results confirm that when a reliable implicit memory test is used amnesia and levels of processing can both be shown to affect implicit memory performance. Thus, functional dissociations between explicit and implicit memory tests may be the consequence of a methodological artifact, that is, a difference in the reliability of the tests.

“…Patients' cognitive profiles were evaluated extensively using a battery of tests (Table 3), including WAISr total intelligence quotient values (TIQ), immediate (IR) and delayed (DR) recall of Rey's 15 words [29], immediate visual memory (IVM) [30], forward (FDS) and backward digit span (BDS), forward (FC) and backward (BC) Corsi Test [31], Raven's 47 progressive matrices (PM) [32], freehand copying of drawings (CD) [33], temporal rules induction [34], and word fluency (WF) [35]. FCb patients had generally preserved cognitive patterns.…”

Cerebellar Damage Impairs Executive Control and Monitoring of Movement Generation

et al. 2014

Executive control of motor responses is a psychological construct of the executive system. Several studies have demonstrated the involvement of the cerebral cortex, basal ganglia, and thalamus in the inhibition of actions and monitoring of performance. The involvement of the cerebellum in cognitive function and its functional interaction with basal ganglia have recently been reported. Based on these findings, we examined the hypothesis of cerebellar involvement in executive control by administering a countermanding task in patients with focal cerebellar damage. The countermanding task requires one to make a movement in response to a ‘go’ signal and to halt it when a ‘stop’ signal is presented. The duration of the go process (reaction time; RT), the duration of the stop process (stop signal reaction time; SSRT), and their relationship, expressed by a psychometric function, are recorded as measures of executive control. All patients had longer go process duration in general and in particular, as a proactive control, as demonstrated by the increase in RT after erroneously performed stop trials. Further, they were defective in the slope of the psychometric function indicating a difficulty on triggering the stop process, although the SSRT did not differ from controls. Notably, their performance was worse when lesions affected deep cerebellar nuclei. Our results support the hypothesis that the cerebellum regulates the executive control of voluntary actions. We speculate that its activity is attributed to specific cerebellar influence over the cortico-striatal loop.
