Psychological variables in the control of brain-computer interfaces

BCI (Brain-Computer Interface) is a system that allows interaction between the human brain and a computer. It is based on analyzing electroencephalographic signals (EEG) and processing them to generate control commands. The study analyzed the possible influence of psychological variables, such as the imaginative kinesthetic capacity and anxiety, in relation to performance in a BCI. All participants (4 male and 19 female students) completed the questionnaires and carried out a session of BCI to control their EEG signals in a virtual setting of a car along a straight road. The group was divided into two subgroups according to their EEG signals or differential responses obtained in the left-right discrimination. Study results showed no significant differences in cognitive variables of imagination or in anxiety. By comparing the degree of participants' BCI control, a new quantitative parameter for comparing performances and making decisions in signal processing was found. The findings, the ongoing research process to refine the control of a BCI, and the interaction of psychological and computer procedures are discussed.     

Bion's Notes on memory and desire – its initial clinical reception in the United States: A note on archival material

While Bion's 1967 memory and desire paper reflected a crucial episode in his clinical thinking during his epistemological period, it was also central to his evolution as a Kleinian psychoanalyst who worked with seriously disturbed adult patients. The author explicates and contextualizes these claims with a new archival document, the Los Angeles Seminars delivered by Bion in April 1967, and the full‐length version of Notes on memory and desire. Bion here instigated a radical departure from years of theory‐laden work when he made his clinical work and ideas accessible to a new audience of American Freudian analysts. While this new group was keenly interested to hear about Bion's clinical technique with both borderline and psychotic patients, there were varied reactions to Bion's ideas on the technical implications of the analyst's abandonment of memory and desire. Both the Los Angeles Seminars and Notes elicited responses ranging from bewilderment, admiration to skepticism amongst his audience of listeners and readers. These materials also however allow for a more complete and systematic presentation of important ideas about analytic technique – and while his ideas in this domain have been long valued and known by many psychoanalysts, this contribution stresses the crucial aspect of the reception of his ideas about technique in a particular American context. American analysts gained a much more explicit idea of how Bion worked analytically, how he listened, formulated interpretations and factored in the analyst's listening receptivity in the here‐and‐now. The author concludes with a consideration of the importance of Bion's American reception in 1967.     

On understanding projective identification in the treatment of psychotic states of mind: The publishing cohort of H. Rosenfeld, H. Segal and W. Bion (1946–1957)

A publishing cohort of Kleinian analysts – Rosenfeld, Segal and Bion – implemented Klein's (1946) notions of projective identification and the 'paranoid ' and 'schizoid ' positions in the understanding of a group of psychotic disorders. The author differentiates Klein's (1946) Notes on some schizoid mechanisms paper from its revised version of 1952, maintaining that it was Rosenfeld's clinical work during this period that helped to centralize Klein's redefinition of projective identification. The stage was set for Segal 's contribution in terms of 'symbolic equations,' where the psychotic's attack on the breast left him incarcerated in internal torment and persecution, where things-in-themselves were confused with what they symbolically represented. Segal in turn linked psychotic to normal, paranoid–schizoid to depressive positions, where by means of projective identification and symbolic imagination, the patient could arouse feelings in the analyst related to sadness, guilt and loss. Bion assumed that psychotic pathology reflected disordered thinking, when the severely disturbed used language as a mode of action. The psychotic was profoundly confused between the use of thought and action in the natural world – where thought was required, he preferred action and vice versa. Bion also drew upon projective identification in a new, broader way, so that analysis could now become more of an intersubjective, bi-directional field of projective and communicational influence between patient and analyst. The paper concludes with the impact of the work of Rosenfeld, Segal and Bion and variations on the technique of analyzing psychotic states in terms of the patient's early history, transference and countertransference.     

The role of the patient's remembered history and unconscious past in the evolution of Betty Joseph's 'Here and now' clinical technique (1959-1989)

The author historicizes one aspect of Betty Joseph's ongoing technical contributions in terms of its originating London kleinian context. Early on she drew upon both the patient's remembered history and unconscious past, linking these experiences in past-to-present transference interpretations in order to effect psychic change. In evolving the technique of 'here and now' analysis, Joseph came to emphasize a communicative definition of projective and introjective identification as well as the significance of enactments while marginalizing the use of part-object anatomical interpretative language. She gradually set aside directly linking the patient's past with the present, compelled now by making direct contact with her patients. She now tracked how difficult patients acted in and responded to interpretations from moment to moment. The author maintains that the explicit and implicit conceptual work of Wilfred Bion as well as Joseph's continuous group workshop for analysts led to an increased understanding of the patient's projective impact on the analyst's countertransference responses, and thereby increased the analyst's capacity with 'difficult to treat' narcissistic spectrum patients described by her colleague, Herbert Rosenfeld. In recent work, while Joseph continues to elucidate what patients recall about their early past, she formats her understanding in terms of a direct analysis of the structure of the patient's projected internal object relations in the transference. The analyst works with the patient's communications and enactments, with a greater emphasis on a more 'inside-to-outside' understanding of transference in contrast to the earlier 'past-to-present' work associated with both Freud and Klein. This investigation concludes with one example of Betty Joseph's significant impact on contemporary kleinian technique by taking up some of Michael Feldman's work. Now the analyst listens to the 'past presented,' the patient's projected internal world, as well as tracks how the patient hears and subtly mishears interpretations for defensive, equilibrium-maintaining purposes, as the analyst attempts to effect psychic change by widening the ego's perceiving functions.
