Event-related potentials to overlapping shapes: Effects of saliency and interference

Visual perception is often challenged by various difficulties that act concomitantly and whose respective impacts may therefore be hard to distinguish. We used event-related potentials to dissociate the impact of target saliency, generated by occlusion, from that of interference produced by incongruent nontargets. In one block, the target (a square) partially occluded another square tilted by 45°. This nontarget square interfered only to a small extent with target perception. In another block, the target was the occluded stimulus, and interference from the nontarget was substantial. Blocks including two kinds of overlapping shapes (a cross and a square) were added to control for the interference effect. Block comparisons revealed that occlusion modulated an occipital N250 and reaction times. In contrast, interference modulated a parietal N380 but not reaction times.     

On the nature of intuitive and delusional thought: Its implications in clinical work with psychotic patients

The author tries to differentiate intuitive imagination from delusional imagination and hypothesises that psychosis alters the system of intuitive thinking, which consequently cannot develop in a dynamic and selective way. Scholars of different disciplines, far removed from psychoanalysis, such as Einstein, Hadamard or Poincar, believe that intuitive thinking works in the unconscious by means of hidden processes, which permit a creative meeting of ideas. Thanks to Bion's work, psychoanalysts have begun to understand that waking thinking is unconsciously intertwined with dream‐work. The delusional construction is similar to a dreamlike sensorial production but, unlike a real dream, it remains in the waking memory and creates characters which live independently of the ‘dreamer's’ awareness. It is a dream that never ends. On the contrary, the real dream disappears when it has brought its communicative task to an end. In the analysis of psychotic patients it is very important to analyse the delusional imagination which dominates the personality and continuously transforms the mental state, twisting emotional truth. The delusional imagination is so deeply rooted in the patient's mental functioning that, even after systematic analysis, the delusional world, which had seemed to disappear, re‐emerges under new configurations. The psychotic core remains encapsulated; it produces unsteadiness and may induce further psychotic states in the patient. The author reports some analytic material of a patient, who, after a delusional episode treated with drugs, shows a vivid psychotic functioning. Some considerations are added on the nature of the psychotic state and on the therapeutic approach used to transform the delusional structure. This paper particularly deals with the difficulty in working through the psychotic episode and in ‘deconstructing’the delusional experience because of the terror connected with it. In the reported case, the analytic work changed the delusional construction into a more benign one characterised by phobic qualities. The analysis of the psychotic transference allowed the focus to be on the hidden work which had been continuously influencing the transferential picture of the analyst and the patient's psychic reality.     

Violence and Latin‐American preadolescents: A study of social brain function and cortisol levels

The present study investigated exposure to violence and its association with brain function and hair cortisol concentrations in Latin‐American preadolescents. Self‐reported victimization scores (JVQ‐R2), brain imaging (fMRI) indices for a social cognition task (the ‘eyes test’), and hair cortisol concentrations were investigated, for the first time, in this population. The eyes test is based on two conditions: attributing mental state or sex to pictures of pairs of eyes (Baron‐Cohen, Wheelwright, Hill, Raste, & Plumb, 2001). The results showed an association among higher victimization scores and (a) less activation of posterior temporoparietal right‐hemisphere areas, in the mental state condition only (including right temporal sulcus and fusiform gyrus); (b) higher functional connectivity indices for the Amygdala and Right Fusiform Gyrus (RFFG) pair of brain regions, also in the mental state condition only; (c) higher hair cortisol concentrations. The results suggest more exposure to violence is associated with significant differences in brain function and connectivity. A putative mechanism of less activation in posterior right‐hemisphere regions and of synchronized Amygdala: RFFG time series was identified in the mental state condition only. The results also suggest measurable effects of exposure to violence in hair cortisol concentrations, which contribute to the reliability of self‐reported scores by young adolescents. The findings are discussed in light of the effects of exposure to violence on brain function and on social‐cognitive development in the adolescent brain.

The Lateralized Linguistic Cerebellum: A Review and a New Hypothesis

During the past 2 decades the collaboration across disciplines and the methodologic and conceptual advances of contemporary neuroscience have brought about a substantial modification of the traditional view of the cerebellum as a mere coordinator of autonomic and somatic motor functions. Growing insights in the neuroanatomy of the cerebellum and its interconnections, evidence from functional neuroimaging and neurophysiological research, and advancements in clinical and experimental neuropsychology have established the view that the cerebellum participates in a much wider range of functions than conventionally accepted. This increase of insight has brought to the fore that the cerebellum modulates cognitive functioning of at least those parts of the brain to which it is reciprocally connected. This article reviews the recently acknowledged role of the cerebellum in cognition and addresses in more detail experimental and clinical data disclosing the modulatory role of the cerebellum in various non-motor language processes such as lexical retrieval, syntax, and language dynamics. In agreement with the findings indicating a topographical organization of the cerebellar structures involved in language pathology we advance the concept of a "lateralized linguistic cerebellum." In our view crossed cerebral diaschisis processes, reflecting a functional depression of supratentorial language areas due to reduced input via cerebellocortical pathways, might represent the relevant pathomechanism for linguistic deficits associated with cerebellar pathology.     

Sandplay in Jungian analysis: matter and symbolic integration

Jung described a way of thinking, tied to sensations and feelings, that is a thought connected to the body. Again in The Archetypes and the Collective Unconscious, Jung (1954) speaks of the symbol as a 'live body', corpus et anima. If the mind cannot credit itself with the discomfort that manifests through the body, this is a sign of a separation between mind and body. A consequence of all this is the literalization of the discomfort which makes it impossible to have a symbolic dimension. Therapy activates a process in which the patient can move from a stage of separation to a possible connection between mind and body, resulting in changes in the level of communication and of awareness. The mind opens itself to symbolization and the body becomes a field for a common language. From our reflections we have come to ascertain that we can speak of analysis only when an imaginary space is achieved, an intermediate space between the patient and the analyst, a space that is created from the intertwining of the symbolic capability of the patient with that of the analyst. Focusing our attention on the use of sandplay in analytic therapy, we know that one puts in the sand box objects that are marks of our psyche, visible traits that contain actions, corporeal movements and feelings. When one focuses on the overall representation built, one can go beyond the literal image and the analyst, keeping alive the image through his symbolic capability, opens the possibility of a dialogue with the symbolic dimension. The imagination as a symbolic thought is the humus that allows the analyst to maintain the intermediate symbolic level open by activating a symbolic process within the dialectic of the analysis.     

Deception, catholicism, and hope: understanding problems in the communication of unfavorable prognoses in traditionally-catholic countries

The doctor's use of deception in appropriate circumstances has commonly been considered a necessity of the medical art. Resistance to full and frank communication is typical of many traditionally Catholic countries, and particularly of Italy, a western country where Catholicism remains particularly influential. The Catholic teaching on truth and lies, and the problem of telling the truth to a severely ill patient is discussed. It is suggested that the contemporary Catholic model of gradually telling a terminal patient the truth, which looks reasonable and feasible in theory, is rarely followed in practice, as in the majority of cases the truth is not told tout court. Problems stem from the way in which medicine is currently practiced in Italy; from the synergism between Catholicism and the medical tradition's grounded paternalism; and from the ambiguity of the term 'hope'. Catholic ethics in fact recommends that the truth must be told without destroying hope, but the Catholic meaning of 'hope' is very different from its meaning in current language.     

Baby talk from the perspective of discourse production: Linguistic choices and context coding by different speakers

Twenty men and 20 women with children under 3 years of age, and 20 men and 20 women without children were asked to select the most suitable utterance for a series of drawings representing different contexts of mother/father-infant interaction. Data were analyzed in three sections related to different hypotheses: In Phase 1, informational content and syntactic construction of sentences were selected in strict relationship with context by all speakers (closeness to context rule); in Phase 2, different speech acts were selected by different speakers within the same context (analysis of illocutionary force and canonicality); in Phase 3, the same contexts were linked to different interactional dimensions for the four groups, which formed different representations of the same interactional scene. Results are discussed in an attempt to integrate specific rules of adult-infant interaction and more general aspects of discourse production.     

Abortion in adolescence

Sexual attitudes and behavior of adolescent females have been the topic of much interest over the past decade. Feelings about contraception, conception, and abortion have been described in relation to the adolescents' beliefs about the possibility of becoming pregnant, who will or will not "protect" them, and the influence of significant others on their decision making. This study explores differences in 35 women who had abortions during their teenage years with 36 women whose abortions occurred after the age of twenty. A demographic questionnaire, the Millon Clinical Multiaxial Inventory, and the Beck Depression Inventory were completed by women who were members of a patient-led support group. Premorbid psychiatric histories, the decision-making process itself, and distressing symptoms postabortion are reported. Specific differences in perceptions of coercion, preabortion suicidal ideation, and nightmares post-abortion were found in the adolescent group. Antisocial and paranoid personality disorders as well as drug abuse and psychotic delusions were found to be significantly higher in the group who aborted as teenagers. Hypotheses regarding the influences of adolescent development on mother/child relationships, power struggles, and the use of fantasy as a coping device are explored.     

Cross-modal and intra-modal binding between identity and location in spatial working memory: The identity of objects does not help recalling their locations

In this study we tested incidental feature-to-location binding in a spatial task, both in unimodal and cross-modal conditions. In Experiment 1 we administered a computerised version of the Corsi Block-Tapping Task (CBTT) in three different conditions: the first one analogous to the original CBTT test; the second one in which locations were associated with unfamiliar images; the third one in which locations were associated with non-verbal sounds. Results showed no effect on performance by the addition of identity information. In Experiment 2, locations on the screen were associated with pitched sounds in two different conditions: one in which different pitches were randomly associated with locations and the other in which pitches were assigned to match the vertical position of the CBTT squares congruently with their frequencies. In Experiment 2 we found marginal evidence of a pitch facilitation effect in the spatial memory task. We ran a third experiment to test the same conditions of Experiment 2 with a within-subject design. Results of Experiment 3 did not confirm the pitch–location facilitation effect. We concluded that the identity of objects does not affect recalling their locations. We discuss our results within the framework of the debate about the mechanisms of “what” and “where” feature binding in working memory.
