Semantic errors reconsidered in the procedural light of stack concepts

The purpose of this paper is to demonstrate the relevance of the stack concept in neuropsycholinguistics, a stack being a file with serially ordered elements. Number names (one, two, three, …) and the names of the days in the week may be viewed in this way. In a stack structure, any element is identified by two pieces of information: the particular stack to which it belongs and its position within that stack. Two experiments are reported that demonstrate a double dissociation. A deep dyslexic patient with agrammatism was found to sort stack elements on the basis of identity of position-within-stacks, while a fluent aphasic with semantic verbal paraphasias used another criterion, grouping together the items of the same stack. First revealed when handling number names, the two psycholinguistic procedures are also shown to be differentially operative with other linguistic material. Introducing the stack concept thus permits a procedural reinterpretation of some “semantic confusions,” particularly but not exclusively those dealing with quantities.     

Pragmatism and Developmentalism in Brazilian Educational Thought in the 1950s/1960

This article proposes to analyse some aspects of the appropriation of New School thinking in Brazil, particularly Deweyan pragmatism, in the 1950s and 1960s. The analysis is based on the assumption that the developmentalist ideology that punctuated the debate on the economic, political and social restructuring of the country in these two decades constituted fertile ground for the return and expansion of pragmatist thinking amongst Brazilian educators, articulating itself, sometimes in contradictory ways, with this ideology. The focus of the analysis will be on the writings of the group of educators which circulated around the figure of Anísio Teixeira, at the time director of the National Institute for Pedagogic Studies (INEP), an organ linked to the Ministry of Education and Culture (MEC), which set itself the task of producing research that would support public policy in the field of education, as well as constituting itself as a center for teacher education and the stimulus and development of innovative experiences in the public school system. The appropriation of Deweyan pragmatism, in this context, had a triple perspective: pragmatism as scientific method, implying a specific conception of science, particularly the social sciences, with emphasis on the application of scientific knowledge in the solution of practical problems; as a way of democratic life; and as a synonym for experimentalism, in the sphere of schooling.     

‘But Do Not Use The Rotted Names’: Theological Adequacy and Homosexuality

The Christian evaluation of homosexuality is based primarily on a model which can view homosexuality only as aberrational. From a Christian theological point of view this model articulates an inadequate vision of the dignity of human being. In its deliberations on the process of church, Vatican Council II implicitly developed a relational-progressive model for understanding the salvific engagement of the complete gift of Godlife and creation. This model, in turn, provides a new basis for understanding human dignity and evaluating homosexuality. Viewed from this perspective homosexuality is able to be considered a sacramental embodiment of Godlife.     

Effects of chronic ethanol consumption on gestation and lactation in rats

Chronic consumption of ethanol during pregnancy and lactation may lead to abnormalities in the fetus or infant. A group of female Wistar rats was submitted to ethanol treatment over a period of a month. A pair-fed control group received sucrose solution isocaloric to ethanol and the control group received water “ad libitum.” Afterward, the females were mated with males over a period of 20 days. At birth, each litter was maximized to eight pups and the remaining ones were decapitated to remove the fetal blood and brains. No significant difference was observed in fetal body and brain weight at birth. During lactation the ethanol and pair-fed groups gained less weight than the control group. After weaning, their weight became similar. Fetal blood glucose levels were decreased in the ethanol-treated group. One hundred percent of the pair-fed and control females delivered live fetuses at term and all survived; only 40% of the females in the ethanol group delivered, and one pup did not survive. Chronic ethanol treatment pointed to a possible reduction in the fertility. It seems likely that the change in body weight of ethanol-fed dams was caused by undernutrition.     

Part of speech and phonological form implied in written-word comprehension: Evidence from homograph disambiguation by normal and aphasic subjects

A sentence construction experiment examining the effect of part of speech and phonological form in written-word comprehension is reported. Normal and aphasic subjects had to write sentences incorporating a given word pair, one word was a homograph (e.g., “bank”) whose meaning was context-biased by the other (e.g., “money”/“river”). The effect of three psycholinguistic factors on subjects' performance was questioned: (i) The relative frequency of one meaning of the homograph as compared to the other meaning; (ii) The lexical/syntactic ambiguity (“ball”/“can”); (iii) The same/different phonological forms of the two meanings (“fair”/“bass”). The results are discussed in the framework of a model in which multiple special-purpose procedures are involved in normal processing, some of them being differentially impaired by brain disease in Broca's and Wernicke's aphasics.     

La Diversité Montréalaise à l’Épreuve de la Ségrégation : Pluralisme et Insertion Résidentielle des Immigrants

Residential segregation is becoming a complex phenomenon in a great number of cities, in which case, it becomes important to use methodological approaches that allow us to take this complexity into account. This article presents a case study of the Montreal situation using a method describing segregation along five dimensions identified by Massey and Denton (Social Forces 67:281–315, 1988): equality, concentration, aggregation, exposition and centralisation, as well as a set of fifteen segregation indices, and seven variables describing the immigrant population. Results indicate that Montreal, in 2001, appeared as a multicultural city characterized by a plurality of immigration patterns of urban insertion.     

Biases in visual orienting to negative and positive scenes in dysphoria: An eye movement study

The study investigated biases for negative information in component processes of visual attention (initial shift vs. maintenance of gaze) in dysphoric and nondysphoric individuals. Eye movements were recorded while participants viewed a series of picture pairs depicting negative, positive, and neutral scenes (each pair presented for 3 s). Biases in initial orienting were assessed from the direction and latency of the initial shift in gaze, whereas biases in the maintenance of attention were assessed from the duration of gaze on the picture that was initially fixated. Results indicated that the dysphoric group showed a significantly greater bias to maintain gaze longer on negative pictures, relative to control pictures, compared with the nondysphoric group. There was no evidence of a dysphoria-related bias in initial shift of orienting to negative cues. Results are consistent with a depression-related bias that operates in the maintenance of attention on negative material.     

Visual experience influences the interactions between fingers and numbers

Though a clear interaction between finger and number representations has been demonstrated, what drives the development of this intertwining remains unclear. Here we tested early blind, late blind and sighted control participants in two counting tasks, each performed under three different conditions: a resting condition, a condition requiring hands movements and a condition requiring feet movements. In the resting condition, every sighted and late blind spontaneously used their fingers, while the majority of early blind did not. Sighted controls and late blind were moreover selectively disrupted by the interfering hand condition, while the early blind who did not use the finger-counting strategy remained unaffected by the interference conditions. These results therefore demonstrate that visual experience plays an important role in implementing the sensori-motor habits that drive the development of finger–number interactions.     

Psychometric Properties and Factorial Structure of the Spence Children's Anxiety Scale (SCAS) in Spanish Adolescents

The Spence Children's Anxiety Scale is an instrument widely applied in the assessment of the most common anxiety disorders in children and adolescents. This study examines its psychometric properties and the factorial structure in a large community sample of Spanish-speaking adolescents (N = 1,374) aged 13 to 17 years. The scale demonstrated strong internal consistency and good convergent and discriminant validity. Factor analysis confirmed the 6-factor original model, providing a good fit of the data for the Spanish sample. The good psychometric properties support its use by clinicians and researchers, adding evidence to the international empirical support for this measure.
