No full textOn the genesis of unilateral micrographia of the progressive type
No full textWe report a patient who, following a focal ischemic lesion of the left basal ganglia, developed right hand micrographia characterised by progressive reduction of letter size during writing (progressive micrographia). The patient did not show relevant cognitive impairments, but achieved pathological scores in tests for verbal fluency, and cognitive flexibility and monitoring. A systematic investigation of the writing performances demonstrated that micrographia showed a clear length effect in whatever writing style or task, while it was not observed in drawing, or in left hand writing to a comparable extent. Right hand progressive micrographia was not affected by a concurrent motor and cognitive load; instead, switching between two kinds of allographic responses and presenting one letter at a time in copying tasks reduced severity of micrographia significantly. These findings support the view that progressive micrographia in our patient could be ascribed to a defect in regulating the motor output on the basis of self-generated strategies. This conclusion would be consistent with neuroimaging evidence about the role of the basal ganglia in the control of motor sequencing, and could suggest that progressive micrographia might be associated with specific executive defects
Metacognition Mediates the Relationship Between Maladaptive Personality Traits and Levels of Personality Functioning: A General Investigation on a Nonclinical Sample
No full textThe impaired ability to reflect on one's own state of mind and that of others (called metacognition or mentalization) is a central feature of personality disorders (PDs). Metacognition involves different specific abilities, which can be selectively impaired with different PDs and personality maladaptive traits. Moreover, research in the field of PDs has indicated that personality features and metacognitive abilities are associated with the severity of personality pathologies. In this study, we tested a mediation model of the interactions between these variables on predicting levels of personality functioning in a sample of adults taken from the general population (N = 775). Results showed that the relationship between personality traits and personality functioning is partially mediated by metacognitive abilities. These findings support the hypothesis that metacognition plays a significant role in predicting the levels of impairment in personality functioning. These findings have several clinical implications
