Cognitive architecture of a mini-brain: the honeybee

Honeybees have small brains, but their behavioural repertoire is impressive. In this article we focus on the extent to which adaptive behaviour in honeybees exceeds elementary forms of learning. We use the concept of modularity of cognitive functions to characterize levels of complexity in the honeybee brain. We show that behavioural complexity in the honeybee cannot be explained by independent functions of vertically arranged, domain-specific processing modules, but requires horizontal integration in a central state, and we identify neural mechanisms that may underlie domain-specific processing and central integration. The honeybee may serve as a useful model for the study of intermediate levels of complexity in cognitive functions and the search for their neural substrates.     

Understanding and Treatment of Narcissistic Personality Disturbances

The author discusses how sexuality on the one hand develops and changes during childhood, but on the other hand, holds onto the old residues of different, earlier phases. In adult sexuality, there always remain enigmatic, regressive, even borderline emotions and feelings from earlier experiences. These residues make sexuality incomprehensible and primitive, but also offer possibilities for dreams, fantasies and creativity later in life. Autoerotic fantasies, object fantasies, enigmatic knowledge, sexuality fantasies and creative thinking are realised via these developmental residues.     

The Relationship Between the MCMI Personality Scales and DSM-III,Axis II

Compared were the personality scales of the Millon Clinical Multiaxial Inventory (MCMI) to the diagnosis of personality disorder, according to the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III]; American Psychiatric Association, 1980), obtained by means of the Structured Interview for the DSM-III Personality Disorders (SIDP). The results from 272 psychiatric outpatients show a good correspondence for the Avoidant and the Dependent scales, a fairly good correspondence for the Schizotypal, the Histrionic, the Borderline, the Narcissistic, and the Paranoid scales, and no correspondence for the Schizoid, the Passive-Aggressive, and the Compulsive scales. The Passive-Aggressive scale seems to be positively correlated to personality disorders in general, whereas the Compulsive scale seems to be negatively correlated to a number of personality disorders.
