RESUMEN
Given that the DSM taxonomy of personality disorders is flawed by severe classificatory problems, the development of alternative classificatory systems, such as the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), has now become a priority. This study examined the internal consistency, second-order factor structure, and criterion validity of a Spanish translation of the DAPP-BQ in two samples: subjects with personality disorder (n = 155) and subjects from the general population (n = 300). Alpha coefficients ranged satisfactorily from .75 to .93. Four second-order factors of Emotional Dysregulation, Dissocial Behavior, Inhibitedness, and Compulsivity were obtained, which were replicable between samples and identical to those reported in the literature. Finally, disordered subjects scored significantly higher than normal subjects on 17 of the 18 DAPP-BQ traits. Some pending issues in the construction of an alternative taxonomy of personality disorders are discussed.

When discrepant stimuli are presented to each eye and fusion is impossible, perception spontaneously oscillates between the two patterns (binocular rivalry). Functional MRI (fMRI) research identified a frontoparietal network in the right hemisphere associated with perceptual transitions, and it has been proposed that this network is at the origin of the perceptual alternations. Neuroimaging results, however, do not imply causality and lesion studies are needed. Here, we studied one patient who had most of the prefrontal cortex disconnected from the rest of the brain after a bilateral frontal leucotomy. His performance in two binocular rivalry tasks was indistinguishable from that of the controls. The results indicate that prefrontal cortex is unnecessary for perceptual alternations during binocular rivalry.
