perseverative errors and more total errors , but did not make significantly more anticipatory errors than control animals. ANTICIPATORY AND PERSEVKRATTVE ERRORS FOLLOWING FRONTAL LESIONS IN THE RAT1 BRKNDA N ...
. The frontal lesion group showed increased anticipatory error as did the parietal group to a lesser extent. The parietal group showed what appeared to be an increase in perseverative behavior. It is suggested ...
Abstract A previous study using a rodent five-choice test of attention found poor choice accuracy and increased perseverative responding following medial prefrontal cortex (mPFC) lesions . As this rat ...

of the affective or motivational significance of errors . Patients with schizophrenia show rigid, perseverative behaviour that is not optimally responsive to outcome. Findings of reduced anterior cingulate cortex ...
; Luria 1980; Szczepanski and Knight 2014), including primate lesion studies (Jacobsen 1935; Harlow et al. 1952), suggest a deficit in “immediate recall” following damage to frontal lobe areas. Subsequently ...
