Visual discrimination by heifers (Bos taurus) of their own species

Species discrimination has been described in several taxa but rarely in domestic animals. In contrast to wild species, domestic species present a great phenotypic variety. This study investigated whether 10 Prim'Holstein heifers (Bos taurus) could discriminate images of cows from images of other domestic animals. The experiment was based on simultaneous discrimination. Responses were obtained through instrumental conditioning using a food reward. In Experiment 1, the reward was associated with a cow face and, in the reversal learning task, with faces of other domestic species. The results showed that in both tasks, cows were able to reach the criterion in few sessions. Therefore, despite great phenotypic variety (a cognitive challenge) cows were able to visually discriminate their own species from other domestic species.

Conceptual framework from the Paris Psychosomatic School: A clinical psychoanalytic approach to oncology1

This article presents further clinical material from the Paris Psychosomatic School ( Aisenstein, 2006 ). The Freudian foundations of psychosomatics are detailed and post-Freudian developments focusing on the contribution of the Paris Psychosomatic School are outlined, in particular, the somatizing process as a result of regression and the somatizing process as a result of drive unbinding. The authors argue that the latter possibly gives rise to progressive and serious illness leading to death. The relationship of classical psychoanalysis to psychotherapeutic treatment from the angle of the Paris school is commented on. The authors then turn to two clinical presentations of women suffering from breast cancer. The method of evaluating the patients’ capacities for undergoing psychotherapeutic treatment and their mental capacity for healing is discussed. The face-to-face psychoanalytic treatment undertaken with the second case is discussed. Finally, the authors recall Freud’s insistence after 1920 on the opposition of the life drives and the death drives, which placed self-destruction at the centre of psychic functioning. They conclude that current research in biology and medicine, notably research concerning programmed cell death, will converge with psychoanalytic psychosomatics to illuminate somatizing processes and demonstrate the relevance of psychoanalytic treatment to patients who are capable of mental reorganization in the course of their illness and medical treatment.     

Situational consistency in behavioral patterns of aggressive boys: Methodological considerations on observational measures

The issue of situational consistency is of great interest for early intervention with aggressive boys, but efforts to show behavior stability across settings have been unsuccessful to date, due principally to methodological problems. It is argued here that a more appropriate matching of response form, interaction partner, and situations should increase the situation consistency of observed behavior. The results support this proposition in that, more crosssetting behavior consistency was found in the pairing of situations where aggressive boys (age 6–7 years) were interacting with an adult female (mother/child versus baby-sitter/child) than in the pairing of situations where the boys were interacting with an adult male (mother/child versus father/child) or with the teacher in a nondyadic situation (classroom). The implications of using an extreme group are also discussed.This research program was funded by Le Conseil Québécois de la Recherche Sociale, the Quebec Government's FCAR research program, the Social Sciences and Humanities Research Council of Canada, the Canadian Ministry of Employment and Immigration, and the University of Montreal FDR program.     

Effects of a visual frame and of low radial accelerations on the visually perceived eye level

The purpose of this study was to determine how the combined effects of a reference frame and of very low gravito-inertial forces produced by centrifugation affect the visually perceived eye level (VPEL). Twenty subjects were instructed to set a luminous target to the VPEL under various experimental conditions involving two main factors: (1) visual context (frameless, frame centered, frame moved down 50 mm, and frame moved up 50 mm) and (2) gravito-inertial context (motionless, Gi₁=9.81001 m/sec² and Gi₂ = 9.95 m/sec²). The visual context significantly reduced the lowering of VPEL in darkness as caused by radial acceleration; this confirms the prevailing role of vision versus propriosomesthesis. However, under condition Gi₂, there was a significant effect on the VPEL in spite of the presence of the luminous frame; this demonstrates that VPEL processing involves both visual and propriosomesthesic information. Furthermore, the VPEL varied linearly with the vertical shift of the luminous frame for any of the gravito-inertial conditions used in this study, but, under condition Gi₂, the VPEL was shifted downward.     

Examen d'une erreur fondamentale dans la perception du hasard

Un des principaux facteurs expliquant le jeu excessif serait les perceptions erronées qu'entretiennent les individus concernant le hasard. Cet article vise à préciser les perceptions du joueur en analysant ses verbalisations lors de la production ou de la reconnaissance de suites aléatoires. Deux études empiriques ont été réalisées. E est prédit que la majorité des gens ont une perception erronée à l'égard du hasard et qu'il existe une relation entre le nombre d'issues possibles (par exemple deux lors du tir d'une pièce de monnaie ou six lors du tir d'un dé) et le nombre de verbalisations erronées faisant référence aux événements passés de la suite. Comme on le prévoyait, près de 70% des verbalisations sont l'expression d'une perception erronée, la plupart se référant à des liens de dépendance entre les événements de la suite. Cependant, l'augmentation du nombre d'issues possibles n'a pas d'effet significatif sur la proportion de perceptions erronées. La discussion met en relief les implications pratiques et théoriques des perceptions inadéquates des joueurs sur l'illusion du contrôle du jeu et des comportements excessifs en résultant.     

Simulation study of a decision-making model of squash competition, phase one: The analysis of the protocol

This study aims at specifying some of the cognitive processes underlying decision-making in squash competition. More specifically, the study focuses on the strategy of the defending player (D) when chosing among three categories of preparation (total preparation for one particular event, partial preparation in favor of one event and absence of biased preparation). D is viewed as an information processing system (IPS) placed in a problem-solving situation, the problem being what decision to reach. The results obtained in a preceding investigation about the nature of the information processed by a player to anticipate and prepare for the opponent's shot in a real game setting, are used to determine a typical protocol of the behavior of D. The analysis of this protocol allows one to formally define (in Backus-Normal-Form) the problem space of D which is also D's internal representation of the task environment. From the problem space are derived (1) the problem behavior graph depicting the search of D through his problem space for a solution, and (2) the production system (a set of conditional statements, each expressing what to do under specific conditions) defining the logic of the search. The results of this first phase of the simulation study of a decision-making model of squash competition show that the cognitive strategy of D is based upon the use of a specific preformed algorithm. This algorithm could be stored in some long-term memory and activated by the current state of information in short-term memory. Finally, the proposed model also leads to the suggestion that the cognitive strategy of the performer may be influenced by a variety of factors such as the experience of the player, the time pressure, the expectancies, the performer's confidence in his predictions and the mistakes caused by incorrect predictions.
