Exploration and learning in capuchin monkeys (Sapajus spp.): the role of action–outcome contingencies

Animals have a strong propensity to explore the environment. Spontaneous exploration has a great biological significance since it allows animals to discover and learn the relation between specific behaviours and their consequences. The role of the contingency between action and outcome for learning has been mainly investigated in instrumental learning settings and much less in free exploration contexts. We tested 16 capuchin monkeys (Sapajus spp.) with a mechatronic platform that allowed complex modules to be manipulated and to produce different outcomes. Experimental subjects could manipulate the modules and discover the contingencies between their own specific actions and the outcomes produced (i.e., the opening and lighting of a box). By contrast, Control subjects could operate on the modules, but the outcomes experienced were those performed by their paired Experimental subjects (“yoked-control” paradigm). In the exploration phase, in which no food reward was present, Experimental subjects spent more time on the board and manipulated the modules more than Yoked subjects. Experimental subjects outperformed Yoked subjects in the following test phase, where success required recalling the effective action so to open the box, now baited with food. These findings demonstrate that the opportunity to experience action–outcome contingencies in the absence of extrinsic rewards promotes capuchins’ exploration and facilitates learning processes. Thus, this intrinsically motivated learning represents a powerful mechanism allowing the acquisition of skills and cognitive competence that the individual can later exploit for adaptive purposes.     

Impaired configural body processing in anorexia nervosa: Evidence from the body inversion effect

Patients with anorexia nervosa (AN) suffer from severe disturbances of body perception. It is unclear, however, whether such disturbances are linked to specific alterations in the processing of body configurations with respect to the local processing of body part details. Here, we compared a consecutive sample of 12 AN patients with a group of 12 age‐, gender‐ and education‐matched controls using an inversion effect paradigm requiring the visual discrimination of upright and inverted pictures of whole bodies, faces and objects. The AN patients presented selective deficits in the discrimination of upright body stimuli, which requires configural processing. Conversely, patients and controls showed comparable abilities in the discrimination of inverted bodies, which involves only detail‐based processing, and in the discrimination of both upright and inverted faces and objects. Importantly, the body inversion effect negatively correlated with the persistence scores at the Temperament and Character Inventory, which evaluates increased tendency to convert a signal of punishment into a signal of reinforcement. These results suggest that the deficits of configural processing in AN patients may be associated with their obsessive worries about body appearance and to the excessive attention to details that characterizes their general perceptual style.     

The psychodynamic of panic attacks: A useful integration of psychoanalysis and neuroscience1

This article tries to explain, in the light of some neuroscientific and psychoanalytical considerations, the repetitive pattern of panic attacks. Freud considered the panic attack as an ‘actual neurosis’ not involving any conflictual process. Recent neuroscientific findings indicate that psychosomatic reactions, set off by a danger situation, depend on the primitive circuit of fear (including the amygdala) characterised by its speed, but lack accurate responses and may also be activated by harmless stimuli perceived erroneously as dangerous. The traumatic terror is stored in implicit memory and may be set off by a conditioned stimulus linked to a previous danger situation. In the panic attack, the traumatic event is created by the imagination and this construction (a micro‐delusion), built in loneliness and anxiety, has the same power as the real trauma. A mutual psychosomatic short‐circuit between body and psyche, in which terror reinforces the somatic reactions and the psychic construction, is established. Therefore, it is important to highlight these constructions in order to analyse and transform them. In the second part of the article the author reviews the main psychoanalytical theories about panic attacks, stressing how, in his opinion, panic attack is a consequence of the breakdown of the defence organisation at various levels and may appear during periods of life crisis. Two patients suffering from a deficit of personal identity are presented. The various organisations and the different levels (biological, neuroscientific, associative, traumatic) of the panic attack determine different kinds of therapeutic approaches (pharmacological, cognitive and psychoanalytical). While the psychopharmacological treatment is aimed at reducing the neurovegetative reaction and the cognitive method is attempting to correct the associative and perceptive processes of fear signals, psychoanalytical therapy represents both a specific means to free patients from panic attacks as well as an indispensable route for their emotional growth.     

Gastroesophageal reflux disease (GERD) and inflammatory bowel disease (IBD): attachment styles and parental bonding

The attachment styles and parental bonding by 64 patients (M age = 43.2 yr., SD = 13.3) with Gastroesophageal Reflux Disease (GERD) were compared with those of 64 patients (M age = 42.2 yr., SD = 13.5) with Inflammatory Bowel Disease (IBD) and 126 Healthy participants (M age = 42.2 yr., SD = 12.1). Analysis of scores on the Attachment Style Questionnaire indicated insecure attachment in both the patient and control groups. The Parental Bonding scores indicated perceptions of Affectionless Control by parents in both patient groups. In particular, the mean Father-Protection subscale scores were significantly higher for in the GERD group than in the Healthy and IBD groups.     

Essential elements of the work of a supervisor

The supervisor’s prime task is to consider from the very beginning the analytic ability of the analyst presenting the case; this can be assessed by observing how the colleague transcribes the clinical material and describes what is meaningful in the session. It is extremely important to understand whether the patient’s suffering is neurotic, or whether he suffers from an initial psychotic disorder. In this latter case, the analyst will know that he cannot employ the same tools that he uses for the neurotic patient. It is fundamental to draw careful attention to the importance of the patient’s personal history. In the process of reconstructing the past, the patient’s difficulties are gradually understood by the analyst, the patient and the supervisor. Given that a memory may be distorted by present emotions and conflicts, the analyst must form meaningful hypotheses that, through reconstructing interaction with the original objects, help to comprehend the precarious equilibrium of the present. Over the course of supervision, I consistently emphasize the construction of the analytic relationship, which is based on the analyst’s mind and of the patient’s ability to communicate emotionally, so as to promote the analysand’s mental growth.

     

Multiracial Identity,Color‐Blind Racial Ideology,and Discrimination: Professional Counseling Implications

Because of the expansive multiracial population growth in the United States, the authors explored multiracial identity integration (MII), color‐blind racial ideology (CBRI), and discrimination using regression analyses with 288 individuals. CBRI and discrimination significantly correlated and predicted MII, with 15.3% of the variance explained by discrimination and CBRI. Moderation analysis revealed that CBRI did not moderate the relationship between discrimination and MII. Continued research among multiracial individuals is recommended to better understand the CBRI and racial identity link.     

Invariant reversible QEEG effects of anesthetics.

Continuous recordings of brain electrical activity were obtained from a group of 176 patients throughout surgical procedures using general anesthesia. Artifact-free data from the 19 electrodes of the International 10/20 System were subjected to quantitative analysis of the electroencephalogram (QEEG). Induction was variously accomplished with etomidate, propofol or thiopental. Anesthesia was maintained throughout the procedures by isoflurane, desflurane or sevoflurane (N = 68), total intravenous anesthesia using propofol (N = 49), or nitrous oxide plus narcotics (N = 59). A set of QEEG measures were found which reversibly displayed high heterogeneity of variance between four states as follows: (1) during induction; (2) just after loss of consciousness (LOC); (3) just before return of consciousness (ROC); (4) just after ROC. Homogeneity of variance across all agents within states was found. Topographic statistical probability images were compared between states. At LOC, power increased in all frequency bands in the power spectrum with the exception of a decrease in gamma activity, and there was a marked anteriorization of power. Additionally, a significant change occurred in hemispheric relationships, with prefrontal and frontal regions of each hemisphere becoming more closely coupled, and anterior and posterior regions on each hemisphere, as well as homologous regions between the two hemispheres, uncoupling. All of these changes reversed upon ROC. Variable resolution electromagnetic tomography (VARETA) was performed to localize salient features of power anteriorization in three dimensions. A common set of neuroanatomical regions appeared to be the locus of the most probable generators of the observed EEG changes.
