Compared to the controls, the patients were impaired at inflecting real irregular verbs but not real regular verbs both for past-participle and present-tense forms, but were not impaired at real regular verbs either for past-participle or present-tense forms. For novel past participles, the patients exhibited this same pattern of impaired production of class II (irregular) forms but spared class I (regular) production. In the present-tense,

patients were impaired at the production of class II forms (which are regular in the present-tense), but spared at production of class I (regular) forms. Contrary to the pattern observed in English, the errors made by the patients on irregulars did not reveal a predominance of regularization Dinaciclib order errors (e.g., digs digged). The findings thus partly replicate prior findings from English, but also reveal new patterns from a language with a more complex morphological system that includes verb classes (which are not SNS-032 research buy possible to test in English). The demonstration of an irregular deficit following temporal-lobe damage in a language other than English reveals the cross-linguistic generality of the basic effect, while also elucidating important language-specific differences in the neurocognitive basis of regular and irregular morphological forms.

“We

report a patient with severe anosognosia for hemiplegia, who recovered instantly and permanently when viewing herself in a video replay. We believe the observed dramatic reinstatement of the patient’s awareness related to her self-observation ‘from the outside’ (3rd person perspective) and ‘off-line’ (at a time later than the actual attempt to execute a movement); her anosognosia had been unaltered when she observed her plegic arm in her ipsilateral visual field (self-observation from a 1st-person perspective

and ‘on-line’). secondly To our knowledge, the role of self-observation in videos or mirrors has not being assessed in AHP to date. Our study provides preliminary evidence that, when right hemisphere damage impairs the ability to update one’s body representation, judgements relying on 3rd-person and off-line self-observation may be spared in some patients and may facilitate 1st person awareness.

“Human observers readily identify objects with moving parts, and recognize their underlying structure even when the component parts undergo complex movement. This suggests the existence of neural representations that are invariant to motion and state of articulation, which together allow our visual system to maintain ‘object constancy’. Ventral temporal cortex has previously been implicated in object perception and in coding object identity, but it is unclear where this is achieved when objects undergo motion-driven shape changes.
