Characterization of speed fluctuation and drag force in young swimmers: A gender comparison

The aim of this study was to compare the speed fluctuation and the drag force in young swimmers between genders. Twenty-three young pubertal swimmers (12 boys and 11 girls) volunteered as subjects. Speed fluctuation was measured using a kinematical mechanical method (i.e., speedo-meter) during a maximal 25-m front crawl bout. Active drag, active drag coefficient and power needed to overcome drag were measured with the velocity perturbation method for another two maximal 25 m front crawl bouts with and without the perturbation device. Passive drag and the passive drag coefficient were estimated using the gliding decay velocity method after a maximal push-off from the wall while being fully immersed. The technique drag index was also assessed as a ratio between active and passive drag. Boys presented meaningfully higher speed fluctuation, active drag, power needed to overcome drag and technique drag index than the girls. There were no significant gender differences for active drag coefficient, passive drag and passive drag coefficient. There were positive and moderate-strong associations between active drag and speed fluctuation when controlling the effects of swim velocity. So, increasing speed fluctuation leads to higher drag force values and those are even higher for boys than for girls.     

Individual Differences in Working Memory Abilities in Healthy Adults

The goal of this study was to understand the role of individual characteristics such as age, gender and education of healthy adults on working memory abilities, as conceptualized in the central executive, phonological loop, and visuospatial sketchpad. The sample comprised 302 adults aged from 18 to 65 with different educational backgrounds. Participants were submitted to a protocol of established neuropsychological tests that were selected to assess the central executive, phonological loop, and visuospatial sketchpad. The results revealed that these factors influenced working memory abilities differentially. Education level influenced all the three components in the same direction. Individuals with higher academic qualifications have better performance in tests assessing the central executive, phonological loop, and visuospatial sketchpad, whereas age affected performance in the task evaluating the central executive. Age and gender also influenced the performance in tasks related to visuospatial sketchpad in the sense that younger individuals or men reveal better visual and spatial abilities as conceptualized in the visuospatial sketchpad.     

Philosophy of Science and Ethics

The issue whether science can be correctly submitted to ethical judgment has been widely debated especially in the 1960s. Those who denied the legitimacy of such a judgment stressed that this would entail an undue limitation of the freedom of science; those who defended such a limitation laid stress on the great dangers that an uncontrolled growth of scientific knowledge has already produced and would continue to produce against humankind. This sterile debate can be settled by recognizing that scientific knowledge can and must be evaluated, as far as its validity is concerned, exclusively through the methodological criteria admitted by the professionals of the single scientific disciplines concerned, and no ethical judgment is pertinent from this point of view. Nevertheless, if we consider science as a particular system of social activities, entailing concrete procedures, conditions and applications, the ethical evaluation of these actions is pertinent and correct. A second question is whether or not the inclusion of these ethical investigations in the specific domain of philosophy of science is correct. If one conceives philosophy of science simply as an epistemology of science consisting in a logical-methodological investigation about the language of scientific theories, this broadening would appear spurious. This view, however, is too narrow and dated: a fully fledged philosophical investigation on the complex phenomenon of science cannot prevent important outlooks and instruments of the philosophical inqujiry (in particular ethics) from legitimately pertaining to the philosophy of science.     

Emotional valence of spoken words influences the spatial orienting of attention

The influence of the affective content of speech on the spatial orienting of auditory attention was examined by adapting the dot probe task. Two words, one of which was emotional in one quarter of the trials, were played simultaneously from a left- and a right-located loudspeaker, respectively, and followed (or not) by a lateralized beep to be detected (Experiments 1 and 2) or localized (Experiment 3). Taboo words induced attentional biases towards their spatial location in all experiments, as did negative words in Experiment 3, but not positive words. Thus, in audition, the identification of an emotional word automatically activates the information about its spatial origin. Moreover, for both word types, attentional biases were only observed when the emotional word was presented on the participant's right side, suggesting that the dominant left hemisphere processing of words constrains the occurrence of spatial congruency effects.     

Eating Disorders: A Bond between Medicine,Culture and Psychoanalysis

Action in connection with the therapeutic process is often equated with acting out. The subtle behaviour that belongs to ?the complicated system of transmitting and receiving unconscious signals? (Sandler), with which the patient attempts to make the analyst behave as the object of transference or to fulfill an unconscious desire, is also described as acting out or micro-acting out (Treurniet). This fine-grained action, however, means nothing; it is not symbolic or communicative action. Its intention is, rather, to trigger effects and induce interactions. It occurs not only on the side of the analysand but also on that of the analyst, and is part of the unconscious communication in the therapeutic process. Presented here are some of the various interactive ways and means with which the analyst is prompted into unconscious action and certain, unnoticed, ways in that he turn ?treats? the patient. The analyst's action responses can bear the character of interpretations with which he may unintentionally reveal how he regards the behaviour of the patient.     

Perversion: a clinical possibility

Abstract

Clinical work with perverse patients presents numerous difficulties to psychoanalysis, be that due to the characteristics typical of the perverse structure, which is founded on the mechanism of disavowal, or to the inefficiency of neutrality and free association in this kind of practice. A study of existing literature on the subject and a thorough examination of their own clinical findings led the authors to propose a different kind of strategy for dealing with transference that would make clinical work with these patients plausible and indicate options for the paralyzing position that is imposed on the analyst by the perverse patient in order to derange the analytic process. By proposing an alternative for the “semblance subject-supposed-knowledge,” the authors defend the idea that clinical work with perverse patients is possible, resulting in a subject less captive of the phantasmagoric scene.

Drummond S et al. Perversion: eine klinische Möglichkeit

Klinische Arbeit mit perversen Patienten bildet zahlreiche Schwierigkeiten für die Psychoanalyse, sei es wegen der Eigenart der perversen Struktur, welche durch den Mechanismus der Verleugnung begründet wird oder sei es wegen der Ineffektivität der Neutralität und freien Assoziation bei dieser Art von Praxis. Ein Studium der vorhandenen Literatur über das Thema und eine gründliche Überprüfung eigener klinischer Befunde führte die Autoren dazu, eine unterschiedliche Art von Strategie des Umgangs mit Übertragung vorzuschlagen. Das würde klinische Arbeit mit diesen Patienten plausibel machen und auf Optionen für die paralysierende Position hinweisen, die dem Analytiker durch den perversen Patienten aufgebürdet wird, um den analytischen Prozess zu stören. Ein Alternative für das “semblance subject-supposed knowledge” vorschlagend, verteidigen die Autoren die Idee, daß klinische Arbeit mit perversen Patienten möglich ist, mit dem Ergebnis eines Subjekts, welches weniger durch die phantasmagorische Szene gefesselt ist.

Drummond S et al. perversión: una posibilidad clínica.

El trabajo clínico con pacientes perversos presenta numerosas dificultades para el psicoanálisis, puede ser debido a las características típicas de la estructura perversa, fundamentado en le mecanismo de repudio, o debido a la ineficacia de la neutralidad y asociación libre en este tipo de práctica. Un estudio de la literatura existente sobre el tema y un examen completo de los hallazgos clínicos, llevó a los autores a proponer un tipo diferente de estrategia para el manejo de la transferencia, que pudiera hacer posible el trabajo clínico con estos pacientes, también indicar opciones para la situación de paralización que estos pacientes imponen al analista para desorganizar el proceso analítico. Con la proposición de una alternativa para la “semblance-subject-supposed knowledge(apariencia del sujeto-supuesto saber),” el autor defiende la idea de que el trabajo clínico con pacientes perversos es posible, resultando un asunto menos cautivo de la escena fantasmagórica.     

Metaphonological abilities of adult illiterates: New evidence of heterogeneity

Abstract

Adult illiterate and literate subjects with at most second-grade education, from the same poor settlement in Brazil, were tested on rhyme judgement, initial syllabic vowel deletion and initial consonant deletion. Corrective feedback was provided continuously throughout the tests. The literate subjects were proficient on all three tasks. Illiterates achieved non-negligible performance on vowel deletion and rhyme judgement, but performed poorly on consonant deletion. These results bring additional support to the notion that metaphonological competence involves separate components which obey different developmental mechanisms.     

Categorical perception of speech sounds in illiterate adults

Children affected by dyslexia exhibit a deficit in the categorical perception of speech sounds, characterized by both poorer discrimination of between-category differences and by better discrimination of within-category differences, compared to normal readers. These categorical perception anomalies might be at the origin of dyslexia, by hampering the set up of grapheme-phoneme correspondences, but they might also be the consequence of poor reading skills, as literacy probably contributes to stabilizing phonological categories. The aim of the present study was to investigate this issue by comparing categorical perception performances of illiterate and literate people. Identification and discrimination responses were collected for a /ba-da/ synthetic place-of-articulation continuum and between-group differences in both categorical perception and in the precision of the categorical boundary were examined. The results showed that illiterate vs. literate people did not differ in categorical perception, thereby suggesting that the categorical perception anomalies displayed by dyslexics are indeed a cause rather than a consequence of their reading problems. However, illiterate people displayed a less precise categorical boundary and a stronger lexical bias, both also associated with dyslexia, which might, therefore, be a specific consequence of written language deprivation or impairment.
