El procesamiento cognoscitivo de las oraciones negativas

Resumen

Dentro del estudio de la comprensión de las oraciones negativas, la revisión del modelo del procesamiento de la negación de Clark ha hecho surgir dos tipos de críticas.

En primer lugar, el gran «margen de libertad» que posee dicho modelo le hace excesivamente ambiguo y difícilmente contrastable, planteando serios problemas en la interpretación de los datos experimentales, y en la formalización del mismo.

En segundo lugar, junto a los teóricos de la «función natural semántica», se ha señalado la imprescindible necesidad de introducir, en el estudio del lenguaje, los llamados factores contextuales y pragmáticos.

RESUMEN

Crespo comienza manifestando que su propósito es sondear, aunque sea de forma elemental, la posibilidad y potencial productividad de una consideración de la racionalidad como elemento explicativo dentro de una teoría social de las actitudes. El autor explica que un concepto no exclusivamente utilitario o instrumental de la racionalidad puede ser de utilidad para comprender ciertos desarrollos de la dinámica actitudinal, en concreto, aquellos en que es posible pensar que cambiamos de actitud porque somos argumentalmente convencidos. Crespo resalta la posibilidad de considerar las actitudes, entendidas como procesos de significación evaluativa o toma de postura respecto a otros significativos, como procesos sociales susceptibles de enjuiciamiento y eventualmente necesitados de legitimación o justificación. El autor finaliza su trabajo repasando extensamente algunas características del concepto de actitud en relación con su carácter evaluativo y su vinculación a la acción. Los comentarios de Amalio Blanco, Charles Antaki y M^a Dolores Avia valorando esta exposición siguen a la misma, al igual que la respuesta de Crespo a estos autores.     

Psychoacoustic cues to emotion in speech prosody and music

There is strong evidence of shared acoustic profiles common to the expression of emotions in music and speech, yet relatively limited understanding of the specific psychoacoustic features involved. This study combined a controlled experiment and computational modelling to investigate the perceptual codes associated with the expression of emotion in the acoustic domain. The empirical stage of the study provided continuous human ratings of emotions perceived in excerpts of film music and natural speech samples. The computational stage created a computer model that retrieves the relevant information from the acoustic stimuli and makes predictions about the emotional expressiveness of speech and music close to the responses of human subjects. We show that a significant part of the listeners’ second-by-second reported emotions to music and speech prosody can be predicted from a set of seven psychoacoustic features: loudness, tempo/speech rate, melody/prosody contour, spectral centroid, spectral flux, sharpness, and roughness. The implications of these results are discussed in the context of cross-modal similarities in the communication of emotion in the acoustic domain.     

Defending the Indispensability Argument: Atoms, Infinity and the Continuum

This paper defends the Quine-Putnam mathematical indispensability argument against two objections raised by Penelope Maddy. The objections concern scientific practices regarding the development of the atomic theory and the role of applied mathematics in the continuum and infinity. I present two alternative accounts by Stephen Brush and Alan Chalmers on the atomic theory. I argue that these two theories are consistent with Quine’s theory of scientific confirmation. I advance some novel versions of the indispensability argument. I argue that these new versions accommodate Maddy’s history of the atomic theory. Counter-examples are provided regarding the role of the mathematical continuum and mathematical infinity in science.     

Lashing Out after Stewing over Public Insults: The Effects of Public Provocation,Provocation Intensity,and Rumination on Triggered Displaced Aggression

Four studies present the first evidence showing that public (vs. private) provocation augments triggered displaced aggression by increasing the perceived intensity of the provocation. This effect is shown to be independent of face‐saving motivation. Following a public or private provocation, Study 1 participants were induced to ruminate or were distracted for 20 min. They then had an opportunity to aggress against another person who either acted in a neutral or mildly annoying fashion (viz. triggering event). As expected, the magnitude of the greater displaced aggression of those who ruminated before the triggering event compared with those distracted was greater under public than private provocation. Study 2 replicated the findings of Study 1 and confirmed that public provocations are experienced as more intense. Studies 3 and 4 both manipulated provocation intensity directly to show that it mediated the moderating effect of public/private provocation found in Study 1. The greater intensity of a public provocation increases reactivity to a subsequent trigger, which in turn, augments triggered displaced aggression. Aggr.

Little Jeremy's Struggle with Autism,Schizophrenia and Parano a

Since its formulation by Bleuler in 1911, the generalisation of the term ''autism'', mainly due to its use by Kanner in 1943 and its remake by authors of Kleinian inspiration, implies problems which mislead us, blurring our perception and understanding of clinical realities. Our psychoanalytical possibilities can be enlarged by a clear knowledge of the history of psychoanalysis, a dynamic approach to psychiatric classification and to problems related to our conception of the setting. On the basis of a case history the author shows how a child and its family worked through major autistic symptoms and proposes new approaches to some psychoanalytical concepts.     

A connectionist model of category learning by individuals with high-functioning autism spectrum disorder

Individuals with autism spectrum disorder (ASD) show atypical patterns of learning and generalization. We explored the possible impacts of autism-related neural abnormalities on perceptual category learning using a neural network model of visual cortical processing. When applied to experiments in which children or adults were trained to classify complex two-dimensional images, the model can account for atypical patterns of perceptual generalization. This is only possible, however, when individual differences in learning are taken into account. In particular, analyses performed with a self-organizing map suggested that individuals with high-functioning ASD show two distinct generalization patterns: one that is comparable to typical patterns, and a second in which there is almost no generalization. The model leads to novel predictions about how individuals will generalize when trained with simplified input sets and can explain why some researchers have failed to detect learning or generalization deficits in prior studies of category learning by individuals with autism. On the basis of these simulations, we propose that deficits in basic neural plasticity mechanisms may be sufficient to account for the atypical patterns of perceptual category learning and generalization associated with autism, but they do not account for why only a subset of individuals with autism would show such deficits. If variations in performance across subgroups reflect heterogeneous neural abnormalities, then future behavioral and neuroimaging studies of individuals with ASD will need to account for such disparities.     

Psychometric properties of a revised Spanish 20-item Toronto Alexithymia Scale adaptation in multiple sclerosis patients

There have been a small number of investigations of alexithymia in multiple sclerosis (MS) using the 20-item Toronto Alexithymia Scale (TAS-20). However, the TAS-20 factor structure has not yet been evaluated in a MS patient sample, and earlier Spanish translations of this instrument require some improvement. We aimed to evaluate the factorial validity and reliability of an improved Spanish translation of the TAS-20 (the TAS-20-S). The TAS-20-S was completed by 221 MS patients. Confirmatory factor analysis was used to compare the fit of six different factor models. Internal consistency and retest reliability coefficients were also computed. The correlated three-factor model and the higher-order factor model made up of Difficulty Identifying Feelings, Difficulty Describing Feelings, and Externally Oriented Thinking achieved the best fit. Alpha coefficients ranged between .87 and .67; mean inter-item correlations ranged between .48 and .20; and retest correlations after 6 months ranged between .61 and .52. A high degree of alexithymia was present in 18.1% of the sample. Reliability and the traditional three-factor structure were demonstrated for the TAS-20-S, which can now be recommended for assessing an aspect of emotional processing in MS patients.     

Burial and the Crossing of Boundaries

This article discusses portrayals of the underworld in classical and contemporary poetry, exploring connections between darkness and light, the underworld, and growth in the natural world. It links them together with the idea of beauty, and especially beauty in writing poetry. It gives examples of how contemporary poets can use innovative and radical forms to suggest the world of the darkness that is the underworld.
