Wittgenstein on Dreaming and Skepticism

In this paper I aim to elucidate Wittgenstein’s claim that the so-called dream argument is senseless. Unlike other interpreters, who understand the sentence “I am dreaming” as contradictory or self-defeating, I intend to elucidate in what sense one should understand it as senseless or, more precisely, as nonsensical. In this sense, I propose to understand the above-mentioned claim in light of Wittgenstein’s criticism of skepticism from the Tractatus logico-philosophicus to his last writings. I intend to show that the words “I am dreaming” are nonsensical in the same sense as the alleged proposition “There are physical objects” or the expression of doubt about the existence of external objects.

     

Regression-based techniques for statistical decision making in single-case designs

The present study evaluates the performance of four methods for estimating regression coefficients used to make statistical decisions about intervention effectiveness in single-case designs. Ordinary least square estimation is compared to two correction techniques dealing with general trend and a procedure that eliminates autocorrelation whenever it is present. Type I error rates and statistical power are studied for experimental conditions defined by the presence or absence of treatment effect (change in level or in slope), general trend, and serial dependence. The results show that empirical Type I error rates do not approach the nominal ones in the presence of autocorrelation or general trend when ordinary and generalized least squares are applied. The techniques controlling trend show lower false alarm rates, but prove to be insufficiently sensitive to existing treatment effects. Consequently, the use of the statistical significance of the regression coefficients for detecting treatment effects is not recommended for short data series.     

Perceptual organization and artificial attention for visual landmarks detection

In biological vision systems, attention mechanisms are responsible for selecting the relevant information from the sensed field of view, so that the complete scene can be analyzed using a sequence of rapid eye saccades. In recent years, efforts have been made to imitate such attention behavior in artificial vision systems, because it allows optimizing the computational resources as they can be focused on the processing of a set of selected regions. In the framework of mobile robotics navigation, this work proposes an artificial model where attention is deployed at the level of objects (visual landmarks) and where new processes for estimating bottom-up and top-down (target-based) saliency maps are employed. Bottom-up attention is implemented through a hierarchical process, whose final result is the perceptual grouping of the image content. The hierarchical grouping is applied using a Combinatorial Pyramid that represents each level of the hierarchy by a combinatorial map. The process takes into account both image regions (faces in the map) and edges (arcs in the map). Top-down attention searches for previously detected landmarks, enabling their re-detection when the robot presumes that it is revisiting a known location. Landmarks are described by a combinatorial submap; thus, this search is conducted through an error-tolerant submap isomorphism procedure.     

Different patterns of dissociation in unilateral spatial neglect

The aim of this paper is to discuss the issue of dissociations found in unilateral spatial neglect according to the modality of space exploration and the nature of the task. For this purpose we present a reanalysis of the data from a recent paper of Gentilini et al. (1989) comparing visual and blindfolded exploration of a computer keyboard and discuss the performance of a left-brain-damaged patient with right visuospatial neglect and left-sided neglect dyslexia. We conclude that unilateral spatial neglect cannot be interpreted as a disruption of a single attentional mechanism, but rather it reflects impaired attentional mechanisms at several levels of cognitive processing.     

The experience of male spouses in the context of breast cancer: a systematic review of the literature

The purpose of this systematic review is to look into how the experience of husbands of women treated for breast cancer is approached in the literature. Between July and August 2015, the databases of PubMed, SciELO and BIREME were searched for papers published in the period January 2005–July 2015; a final sample of 23 papers was defined. The studies listed several negative and positive aspects of the experience, such as financial difficulties, psychological distress, lack of coping skills among family members, social recognition of the role of caregiver, acquisition of new responsibilities and the maturing of family members.     

Social cognitive career theory and the prediction of interests and choice goals in the computing disciplines

We tested the fit of the social cognitive choice model [Lent, R.W., Brown, S.D., & Hackett, G. (1994). Toward a unifying social cognitive theory of career and academic interest, choice, and performance [Monograph]. Journal of Vocational Behavior, 45, 79-122] to the data across gender, educational level, and type of university among students in a variety of computing disciplines. Participants were 1208 students at 21 historically Black and 21 predominantly White universities. They completed measures of self-efficacy, outcome expectations, interests, goals, and social supports and barriers with respect to computing majors. The SCCT model yielded adequate fit to the data across each of the grouping variables. Implications for future research on SCCT’s choice hypotheses in the context of science and engineering-related fields are discussed.     

Emotion in an alliance rupture and resolution sequence: A theory‐building case study

Aims: Alliance rupture and resolution processes are occasions for the client to have his or her core interpersonal patterns activated in the here and now of the therapy and to negotiate them with the therapist. So far, no studies have been conducted on emotional processing, from a sequential perspective using distinct emotion categories, in alliance rupture and resolution therapy sessions. This is the objective of this theory‐building case study. Method: This client underwent a 34‐session long, psychodynamic psychotherapy within the context of an open trial. An alliance rupture‐resolution sequence of two subsequent sessions, along with a third control session, was selected from this case and these sessions were rated using the Classification of Affective‐Meaning States (CAMS), an observer‐rated method to classify distinct emotions, according to current emotion‐focused models. Results: The results indicate that the rupture session was associated, above all, with core maladaptive fear, evoked in the actual here and now of the therapeutic relationship, whereas the resolution session was associated with the expression and experience of adaptive hurt as regards biographical issues of the client. Discussion: These results are discussed with regard to the alliance rupture and resolution model and the exploration of integrating client's emotional processing in the model.     

Body and meaning

Abstract

This paper discusses the very important but disregarded theme of somatization. Somatizers comprise a wide-ranging group of patients, who normally choose to consult doctors rather than psychoanalysts for treatment. We present two clinical reports of somatizing patients in which the psychoanalyst played a considerable role in the study and treatment of their problems. The subjects were not only totally relieved of their physical symptoms, but also dramatically changed their psychic lives.
