Instructions for Climbing the Ladder (The Minimalism of Wittgenstein's Tractatus)

I aim to present a solution to the apparent paradox of the Tractatus by means of a minimalist reading grounded in the idea that the correct logical symbolism alone “finally solves” in essentials the philosophical problems. I argue that although the sentences of the Tractatus are nonsensical, rules presented in its symbolism are not. The symbolism itself expresses only a priori rules of logic through schematic variables that do not say anything. I argue that this reading correctly expresses the ladder structure of the book, and that it can account for Wittgenstein's critique of the Tractatus in Some Remarks on Logical Form.     

Investigating the contribution of metacontrast to the Fröhlich effect for size

According to the Fr?hlich effect, observers perceive the initial position of a fast moving stimulus displaced in the direction of motion. On the basis of Kirschfeld and Kammer's as well as Fr?hlich's original assumption that metacontrast plays an important role in the emergence of the phenomenon, we predicted different amounts of misperception for stimulus enlargement compared to stimulus reduction. These basic predictions were confirmed in Experiment 1. In Experiment 2, we investigated whether an overestimation-bias might account for these results. But the overestimation of non-changing stimuli was too small to adequately explain the dissociation. In Experiment 3, we predicted and found different effects of the factor stimulus lightness on misperception in the enlargement and reduction condition. In Experiment 4, we showed that misperception in the enlargement condition is reduced when frames are used instead of filled stimuli, as in the earlier experiments. Results are discussed with respect to the original Fr?hlich effect.     

Getting stuck or stepping back: Effects of obstacles and construal level in the negotiation of creative solutions

Difficult issues in negotiation act as interfering forces but their effects on negotiation processes and outcomes are unclear. Perhaps facing such obstacles leads individuals to take a step back, attend to the big picture and, therefore, to be able to craft creative, mutually beneficial solutions. Alternatively, facing obstacles may lead negotiators to focus narrowly on the obstacle issue, so that they no longer consider issues simultaneously, and forego the possibility to reach high quality, integrative agreements. Three experiments involving face-to-face negotiation support the “getting stuck” hypothesis, but only when negotiators are in a local processing mode and not when they are in a global processing mode. Implications for the art and science of negotiation, and for construal level theory, are discussed.     

Weight Bias Internalization Scale Discriminates Obese and Overweight Patients with Different Severity Levels of Depression: the Italian Version of the WBIS

We have investigated the psychometric properties of the Italian version of the weight bias internalization scale (WBIS) in overweight and obese patients who were attending weight loss programs. Participants were 386 overweight and obese patients admitted in two medical centers specializing in the treatment of obesity. All the patients were administered the WBIS, and measures of binge eating, depression, self-esteem, and body dissatisfaction. Confirmatory factor analysis failed to confirm the fit of the original 11-item unidimensional model. Item analysis and exploratory factor analysis indicated that 9 items included in the original measure (the items 1 and 9 were excluded because low item-total correlations) formed a reliable unidimensional measure of internalized weight bias (WBIS-9). The WBIS-9 was significantly correlated with convergent measures and was able to categorize individuals with different severity levels of depression (sensitivity of 0.72 and specificity of 0.70). The WBIS-9 may be useful in clinical practice to discriminate patients with more severe psychopathology, comorbid disordered eating patterns, and risk for poor outcomes.     

The effectiveness of university counselling for improving academic outcomes and well-being

The work discusses the effectiveness of the counselling treatment to enhance student academic success. The participants were randomly assigned to either an experimental group (66 students who had completed counselling treatment) or a wait-list comparison group (44 students). The Adult Self Report (ASR) by Achenbach and Rescorla [2003. Manual for the ASEBA adult forms & profiles. Burlington, VT: Research Center for Children, Youth, & Families, University of Vermont] and the Outcome Questionnaire 45 (OQ-45) by Lambert and Hill [1994. Assessing psychotherapy outcomes and processes. In A. E. Bergin & S. L. Garfield (Eds.), Handbook of psychotherapy and behavior change (pp. 72–113). New York: John Wiley] were applied before and after the counselling sessions. Data show statistically significant decrease in the ASR clinical scales for both internalising and externalising problems after counselling as well as in the OQ-45 scores for distress symptoms and relationship difficulties. Compared with the control group, the students who received counselling exhibited a significant recovery regarding their progress with their studies.     

Exercise commitment and proneness to eating disorders in a group of physical education teachers

The study examined the association of exercise commitment with proneness to eating disorders in 50 physical education teachers who had been practicing various aerobic sports at least three times a week for at least 5 years. Significant coefficients were found between Commitment to Exercise Scale scores, the number of weekly training sessions, and scores on the Eating Disorders Inventory-2 scales measuring Maturity Fears, Social Insecurity, Perfectionism, and Asceticism. However, no relationship was found between the Commitment to Exercise Scale and the Eating Disorders Inventory-2 variables measuring anorexic tendencies (such as Drive for Thinness, Body Dissatisfaction, and Bulimia). Findings suggest the presence of some psychological factors common to both anorexic tendencies and excessive exercising but not complete overlap, so a rather more complex pattern of relationships appears to be mediated by sex and personality characteristics.     

Motion misperception caused by feedback connections: A neural model simulating the Fröhlich effect

When asked to indicate the starting position of a fast moving stimulus, observers do not indicate the actual starting position but a later position on the motion trajectory. This perceptual illusion is known as the “Fröhlich effect”. We present a neural model aimed at simulating this phenomenon based on feedforward and feedback connections. The basic simulation mechanisms seem to be compatible with the attentional and the motion extrapolation account. A comparison between simulated and empirical results showed that the model is capable of generating the same main effects as those found in the empirical data.

Social exclusion lowers working memory capacity in gay-men but not in heterosexual-men

Because sexual orientation is a crucial factor in social discrimination, this study assessed how the working memory capacity of gay-men and heterosexual-men is affected by a social exclusion event (N = 88). To manipulate the experience of social exclusion participants were included or excluded from a game of Cyberball. To assess working memory capacity, participants had to recall a series of letters while performing math problems in an automated version of the operation span task. The results of this small study, showed the sexual orientation of participants interacted with variations in belonging such that being ostracized (but not being included) lowered the working memory capacity of gay-men relative to heterosexual-men. Implications for research on belonging, social exclusion, and stereotype threat are discussed.
