Possibilities and limits of mind-reading: A neurophilosophical perspective

Access to other minds once presupposed other individuals’ expressions and narrations. Today, several methods have been developed which can measure brain states relevant for assessments of mental states without 1st person overt external behavior or speech. Functional magnetic resonance imaging and trace conditioning are used clinically to identify patterns of activity in the brain that suggest the presence of consciousness in people suffering from severe consciousness disorders and methods to communicate cerebrally with patients who are motorically unable to communicate. The techniques are also used non-clinically to access subjective awareness in adults and infants. In this article we inspect technical and theoretical limits on brain–machine interface access to other minds. We argue that these techniques hold promises of important medical breakthroughs, open up new vistas of communication, and of understanding the infant mind. Yet they also give rise to ethical concerns, notably misuse as a consequence of hypes and misinterpretations.     

Intra-Household Arrangements and Economic Satisfaction

This paper studies the nature of intra-household arrangements in Mexico on the basis of the relationship between a person’s economic satisfaction and her household income. It also studies different theories of the family. The main results support the argument that Mexican families are mostly altruistic and communitarian, with the evidence rejecting a cooperative-bargaining model in Mexican families. Special consideration is given to the situation in low-income families, where marginalization from the household’s economic resources may expose a person to substantially severe economic deprivation. Intra-household arrangements may vary across countries and cultures. Thus, their understanding is crucial for making cross-country comparisons based on household income and per-capita income measures.     

Life satisfaction and satisfaction in domains of life: is it a simple relationship?

This paper studies the nature of the relationship between life satisfaction and satisfaction in domains of life. The domains-of-life literature assumes that a person’s overall satisfaction with his or her life depends on his or her satisfaction in many concrete areas of life, which are classified into a few main domains of life. This paper addresses the issue of what characteristics the relationship between life satisfaction and satisfaction in domains of life has by focusing on its specification. The domains-of-life literature has commonly assumed that an additive relationship between domains satisfaction and life satisfaction does exist. This paper argues that the use of an additive relationship has substantially restricted our comprehension of the relationship; since it makes impossible to empirically address questions such as: Is life satisfaction just a weighted average of domain satisfactions? How easy is it to substitute satisfaction in one domain by satisfaction in another? Is it reasonable to expect similar additional benefits when we continuously improve satisfaction in one domain? What happens with our life satisfaction when we manage to continuously improve satisfaction in all domains? What happens with the importance of one domain when satisfaction in another domain declines? The paper argues that there could be substantial gains in the understanding of the relationship by assuming alternative specifications. At an empirical level the investigation works with four different specifications: an additive relationship, a semi-logarithm relationship, a logarithm–logarithm relationship, and a constant elasticity of substitution (CES) relationship. Using a database from Mexico, the investigation finds out that an additive specification provides – at least for Mexico – a goodness of fit similar to those of alternative specifications. However, there are some relevant issues in the relationship between domains satisfaction and overall life satisfaction that cannot be studied with an additive specification; hence, the?use of an alternative specification – in particular a CES specification – is preferable if the objective is to understand rather than to predict life satisfaction.     

Searching for Spiritual Signatures in SETI Research

The Search for Extraterrestrial Intelligence (SETI) research assumes that we live in an intelligence-friendly universe. But do we live in a spiritual-friendly universe? We include the spiritual quest in a new multidisciplinary approach to SETI. In a thought experiment, we consider two types of alien civilizations by including a Spiritual factor in the Drake Equation. Using the analogy of planetary biomarkers and the concept of noosphere introduced by Teilhard de Chardin, we propose two spiritual markers that could evidence the presence of a noosphere in an exoplanet.     

Instructions, illusory self-tilt and the rod-and-frame test

If an illusion of self-tilt is involved in rod-and-frame test performance, then instructions to adjust the rod to the body midline (egocentric instructions) should result in less rod adjustment error than the standard instructions for the rod-and-frame test to adjust the rod to the gravitational vertical. Two experiments were designed to examine this possibility. The results of the first experiment indicate that the tilted rod-and-frame display induces an illusion of self-tilt in the opposite direction. Significant differences between instructional conditions were found in the second experiment as expected. Other rod-and-frame studies are discussed in view of these findings.     

Visual scanning during pattern recognition in children and adults

Eye movement and fixation responses of 3- to 6-year-old children and adults were recorded during a pattern recognition task. During familiarization, fixations were more repetitive and less extensive for older subjects. The fixation patterns of older children who were consistently able to solve the recognition problems were like those of the adults. Unsuccessful 4- to 6-year-olds spent more time fixating the modified area of the nonstandard pattern presented in paired comparison with the standard, even though their final decision was false. Thus, preschool children were able to locate relevant visual information even when they did not use this information to solve tasks. The results suggest that visual fixations do not always reflect active attention, and that direct fixations of visual information are clearly not sufficient and may not be necessary for problem solving.     

Utility of composite and multiple criteria measuring discriminative efficiency in personnel selection

The present study examined the utility of decision making in personnel selection comparing multiple and composite criteria by discriminative efficiency, in a bricklaying training program. We have found valid predictors (aptitudes, personality and experience) with different forms of the criterion, the ERPF scale, in logistic and multiple regression analysis. Results seem indicate that there is not a better criterion, so it depends on different conditions and different aims to reach. We proposed criteria as combining measures but not opposed.     

Why do we share aggressive online content? Testing a short cycle model

The present study aimed to observe the impacts of aggressive online content exposure and personality on aggressive content sharing, considering the mediating role of positive and negative affects. A total of 302 Brazilians, equally divided into two groups, participated in a social network simulation, being exposed to aggressive (experimental group) or neutral (control group) posts and choosing what they would like to share on this site (among aggressive or nonaggressive material). A factorial MANOVA showed a significant difference for positive and negative affects and aggressive content sharing (Wilks' Λ = 0.936; F[3, 298] = 6.812; p = .001; η² = 0.064). Through structural equation modeling, an explanatory model was also tested, in which this behavior was directly predicted by aggressive online content exposure and suffered indirect effects from openness, conscientiousness, and extroversion, mediated by positive affects (goodness-of-fit index = 0.997, comparative fit-index = 0.998, Tucker-Lewis index = 0.996, SRMR = 0.028, root-mean-square error of approximation = 0.035, CI = 0.003−0.054). It is possible to conclude that the objectives are met, highlighting the contribution to understanding aggressive online behavior through the proximal processes described in the general aggression model.
