Dreaming and cognition in patients with frontotemporal dysfunction

Individuals with Parkinson’s disease (PD) and temporal lobe epilepsy (TLE) have hallucinations and mild cognitive dysfunction. The objective of this work was to study dreams in PD and TLE patients using a common functional model of dream production involving the limbic and paralimbic structures.Dreams were characterised in early-stage PD (19 males) and TLE patients (52) with dream diaries classified by the Hall van de Castle system and were compared with matched controls.In PD, there were significant differences between patients’ dreams and those of controls: animals, physical aggression, and a befriender were more common in patients, and aggressor and bodily misfortunes were less common. The dreams of patients with frontal dysfunction showed more aggressive features.TLE patients had lower recall than PD patients and a higher proportion of dreams involving family and familiar settings, lower proportions involving success, and a higher incidence of frontal dysfunction.The dreams of PD and TLE patients share important features.     

Prevalence and associated factors with body image dissatisfaction among adults in southern Brazil: A population-based study

We investigated the prevalence of body image dissatisfaction (BID) and associated factors in Florianopolis, Brazil. BID was analyzed in a sample (N = 1720) of adults through the Figure Rating Scale. The independent variables were sociodemographic factors, health behaviors, and morbidities. A multinomial logistic regression analysis was used. More men (14.2%) than women (6.1%) presented BID by being lighter than ideal (LI). Conversely, more women (66.6%) than men (46.3%) showed BID by being heavier than ideal (HI). BID by being HI was higher among older women, those with high BMI and those with a partner. In men, lower BMI and the presence of common mental disorders were associated with BID due to being LI. Advanced ages, alcohol abuse, physical inactivity, and obesity were associated with BID due to being HI. We must consider different public health interventions for men and women to reduce BID in Brazilian adults.     

On Ultrafilter Logic and Special Functions

Logics for generally were introduced for handling assertions with vague notions,such as generally, most, several, etc., by generalized quantifiers, ultrafilter logic being an interesting case. Here, we show that ultrafilter logic can be faithfully embedded into a first-order theory of certain functions, called coherent. We also use generic functions (akin to Skolem functions) to enable elimination of the generalized quantifier. These devices permit using methods for classical first-order logic to reason about consequence in ultrafilter logic.Presented by André Fuhrmann     

Effect of scene complexity on colour constancy with real three-dimensional scenes and objects

The effect of scene complexity on colour constancy was tested with a novel technique in which a virtual image of a real 3-D test object was projected into a real 3-D scene. Observers made discriminations between illuminant and material changes in simple and complex scenes. The extent of colour constancy achieved varied little with either scene structure or test-object colour, suggesting a dominant role of local cues in determining surface-colour judgments.     

What is Pragmatism in Brazil Today?

This paper analyses the relations between Pragmatism and Brazilian culture, nowadays defined as a plural culture. It shows that the introduction of Pragmatism into Brazilian educational movements in the past actually made such culture much more receptive to pragmatist ideas. After discussing the concepts of truth and minimalism on Richard Rorty’s Philosophical Papers, the authors conclude that Brazilian education today is receptive to the conception in which new narratives can be used as a powerful instrument to change the world.     

Measures of temporal discrimination in fixed-interval performance: A case study in archiving data

The primary data of many experimental studies of animal learning and performance consist of the times at which stimuli and reinforcers were delivered, and the times at which responses occurred. The articles based on most of these studies report selected data, either from some sessions or some animals, or summary measures of the animals’ behavior. The primary data are sufficient to produce any of the selected and summary measures, but the selected and summarized data cannot produce many of the measures used in other experimental reports. It is now feasible to archive the primary data from animal behavior experiments so that they are accessible for others to perform secondary analysis. The value of such secondary analysis of archived data is described with a case study in which rats were trained on three fixed-interval schedules of reinforcement.

The costs and benefits of writing, talking, and thinking about life's triumphs and defeats

Three studies considered the consequences of writing, talking, and thinking about significant events. In Studies 1 and 2, students wrote, talked into a tape recorder, or thought privately about their worst (N = 96) or happiest experience (N = 111) for 15 min each during 3 consecutive days. In Study 3 (N = 112), students wrote or thought about their happiest day; half systematically analyzed, and half repetitively replayed this day. Well-being and health measures were administered before each study's manipulation and 4 weeks after. As predicted, in Study 1, participants who processed a negative experience through writing or talking reported improved life satisfaction and enhanced mental and physical health relative to those who thought about it. The reverse effect for life satisfaction was observed in Study 2, which focused on positive experiences. Study 3 examined possible mechanisms underlying these effects. Students who wrote about their happiest moments--especially when analyzing them--experienced reduced well-being and physical health relative to those who replayed these moments. Results are discussed in light of current understanding of the effects of processing life events.     

Emotion regulation abilities and the quality of social interaction

Emotion regulation abilities, measured on a test of emotional intelligence, were related to several indicators of the quality of individuals' social interactions with peers. In a sample of 76 college students, emotion regulation abilities were associated with both self-reports and peer nominations of interpersonal sensitivity and prosocial tendencies, the proportion of positive vs. negative peer nominations, and reciprocal friendship nominations. These relationships remained statistically significant after controlling for the Big Five personality traits as well as verbal and fluid intelligence.     

Moral Emotions

Emotions can be the subject of moral judgments; they can also constitute the basis for moral judgments. The apparent circularity which arises if we accept both of these claims is the central topic of this paper: how can emotions be both judge and party in the moral court? The answer I offer regards all emotions as potentially relevant to ethics, rather than singling out a privileged set of moral emotions. It relies on taking a moderate position both on the question of the naturalness of emotions and on that of their objectivity as revealers of value: emotions are neither simply natural nor socially constructed, and they apprehend objective values, but those values are multi‐dimensional and relative to human realities. The “axiological” position I defend jettisons the usual foundations for ethical judgments, and grounds these judgments instead on a rationally informed reflective equilibrium of comprehensive emotional attitudes, tempered with a dose of irony.
