Psychosis,symbol, affectivity 2: another perspective on the treatment of psychotic disorder

This is the second of two papers concerning our study into an integrated approach to psychotic disorders conducted at the University Psychiatry Unit of Palermo’s Polyclinic over approximately 15 years; this paper concentrates on the clinical phenomena. The study aimed to find the best possible treatment and to improve the prognosis of this patient group. We have explored the efficacy of a range of psycho-therapeutic (cognitive-behavioural, systemic-relational, psychodynamic, group and others), psycho-pharmaceutical, psychiatric rehabilitative and psycho-educational treatments, with a hermeneutic approach instead of a systematic one. The study’s conclusions, described in the paper, are that all psychotic functions start with a nuclear psychic issue connected to emotional development. We describe how the most significant symptoms of acute psychotic manifestations (delusions and misperceptions) make use of an encrypted psychological meaning that can be decoded through the patient’s symbolic language. This language is a key element in diagnosis and in the choice of treatment. The paper describes how we revised our understanding of psychosis from being a brain disease to being a process aimed at the rearrangement of psychic functioning. Our significant results are described.

Use of slope and feature cues in pigeon (Columba livia) goal-searching behavior

Terrain slope provides a directional frame of reference for reorientation and navigation, similar to cardinal directions. Previous studies have shown that, in a goal location task, slope is a very salient cue and that pigeons tend to rely on it even if it is not the most informative cue. Such a strong dependence on one type of information, when there are more effective predictors of reward, is a key premise for a modular view of information processing. Here we tested the provocative hypothesis of a "slope module" for reorientation in slanted environments. Pigeons had to solve a goal location task using slope or another, theoretically salient cue: a beacon feature. Overall, searching behavior was controlled almost equally by the two cues. The fact that, for the first time, slope failed to capture most of the associative strength allows us to reject a strong modularity view and suggests instead that there is competition between cues based on salience. As an interesting additional finding, the reliance on slope and the feature was affected by training location (uphill vs. downhill), suggesting the possibility of a modulatory role of effort on the cue-weighting mechanism of reorientation.     

Perversion and infancy and adolescence

Abstract

Studying the works of Freud and Lacan, the authors carried out research on perversion in childhood. Their work covered the perverse polymorphism of infantile sexuality and the perception of the anatomic difference between the sexes that leads the child to create sexual theories and fantasies. The phallic mother and the fetish are viewed as imaginary solutions directly related to the Oedipus and castration complexes. In perversion, a particular position is taken in relation to the Oedipus complex: a serious flaw occurs in the symbolization of the law, and the mechanisms of denial and disavowal take form. Sexuality requires a second “logical time,” separated from infancy by the latency period, in order to confirm (in action) that a fixed position of jouissance (enjoyment) has actually been established. This can only happen in a period after adolescent enhancement. The distinction between perverse traces and a perverse structure is made, taking into account the fact that, in the case of child analysis, the analyst should free the child from the family fantasy and help him/her to build his/her own fantasy.

Campos Santoro V. et al. Perversion und Kindheit und Adoleszenz.

Im Studium der Arbeiten von Freud und Lacan haben die Autoren Forschung über Perversion in der Kindheit gemacht. Die Studien behandeln den perversen Polymorphismus der infantilen Sexualität und die Wahrnehmung des anatomischen Unterschiedes zwischen den Geschlechtern, welche das Kind dazu führt, Sexual-Theorien und Phatasien zu schaffen.

Die phallische Mutter und der Fetisch werden als imaginäre Lösungen angesehen, die sich direkt auf den Ödipus- und Kastrations-Komplex beziehen. Bei der Perversion wird eine besondere Position in Bezug auf den Ödipus angenommen; ein ernsthafter Mangel tritt bei der Symbolisierung des Rechts auf; die Mechanismen der Verneinung und der Verleugnung bilden sich. Sexualität erfordert eine zweite “logische Zeit”, von der Kindheit durch die Latenz Periode getrennt, um (in der Handlung) zu bestätigen, daß eine fixierte Position der jouissance (Vergnügung) sich tatsächlich etabliert hat. Das kann sich nur in einer Periode nach der adoleszenten Verstärkung ereignen.

Es wird die Unterscheidung zwischen perversen Spuren und einer perversen Struktur gemacht, in Rechnung stellend, daß im Fall der Kinder-Analyse der Analytiker das Kind von der Familien-Phantasie befreien sollte und ihm/ihr helfen sollte, seine/ihre Phantasie auszubilden.

Campos Santoro V. Perversión e infancia y adolescencia.

Estudiando los trabajos de Freud y Lacan, los autores han investigado la perversión en la niñez. Los estudios cubren la sexualidad infantil perversa polimorfa y la percepción de la diferencia anatómica entre los sexos, que llevan al niño a crear teorías sexuales y fantasías.

La madre fálica y el fetiche son vistos como soluciones imaginarias relacionadas directamente con el complejo de Edipo y de castración. La perversión, toma una posición particular en relación al Edipo; un fallo importante tiene lugar en la simbolización de la ley; los mecanismos de negación y repudio toman forma. La sexualidad requiere un segundo “tiempo lógico” separado de la infancia por el periodo de latencia, para confirmar (en acto) que una posición fija de jouissance (goce) se ha establecido. Esto solo puede ocurrir en un periodo posterior a la intensificación adolescente.

La distinción entre las huellas perversas y la estructura perversa se ha hecho, teniendo en cuenta que, en el caso del análisis de niños, el analista debe librar al niño de la fantasía familiar y ayudar a el/ella a construir su propia fantasía.     

A Modeling Study of Potential Sources of Curvature in Human Reaching Movements

The authors of this article suggest that the slight but consistent posture-dependent curvature of the spatial paths in the kinematic transformation between intrinsic and extrinsic coordinates may result in a systematic curvature of movements initially planned as straight-line trajectories toward the target. A kinematic planning model is presented that takes into account the anisotropy of the intrinsic and extrinsic transformation and tends to avoid movements that require excessive joint rotations by introducing slight deviations from a straight-line trajectory. Preliminary simulations showed reasonably good agreement with experimental data, especially considering that the current model is strictly based on kinematics. A quantitative analysis showed that the strategy used in the model achieves a favorable compromise between straight-line movements and angular joint changes: By slightly increasing the spatial length of the movement (i.e., by introducing curvature), an individual can greatly reduce the total amount of joint rotation required to produce the movement.     

Reorienting with terrain slope and landmarks

Orientation (or reorientation) is the first step in navigation, because establishing a spatial frame of reference is essential for a sense of location and heading direction. Recent research on nonhuman animals has revealed that the vertical component of an environment provides an important source of spatial information, in both terrestrial and aquatic settings. Nonetheless, humans show large individual and sex differences in the ability to use terrain slope for reorientation. To understand why some participants—mainly women—exhibit a difficulty with slope, we tested reorientation in a richer environment than had been used previously, including both a tilted floor and a set of distinct objects that could be used as landmarks. This environment allowed for the use of two different strategies for solving the task, one based on directional cues (slope gradient) and one based on positional cues (landmarks). Overall, rather than using both cues, participants tended to focus on just one. Although men and women did not differ significantly in their encoding of or reliance on the two strategies, men showed greater confidence in solving the reorientation task. These facts suggest that one possible cause of the female difficulty with slope might be a generally lower spatial confidence during reorientation.
