Revisiting the category effect: the influence of meaning and search strategy on the efficiency of visual search

A series of experiments evaluated whether the category membership of objects influences the efficiency of visual search (the category effect). Participants were trained to associate meaningful verbal labels with simple shapes so that it was possible to vary the categorical relationship between targets and distractors in the search displays while counterbalancing for the visual similarity of the targets and distractors. Participants were instructed (a) to simply search for the unique item in the displays, (b) to search for the unique item while adopting an active search strategy or (c) to search for the unique item while adopting a passive search strategy. The efficiency of search for targets embedded among distractors from the same category or different category was assessed in terms of the slopes of the search functions for detecting the targets. The results showed that the categorical relationship between targets and distractors influences the efficiency of visual search when participants adopt a passive search strategy but not when participants adopt an active search strategy.     

Patterns of peripheral paralexia: pure alexia and the forgotten visual dyslexia?

The concept of visual dyslexia put forward by Marshall and Newcombe (1973) is assessed. After a long period of neglect it was resurrected in the late 1990s in a narrow form. In the current paper it is proposed that a wider form of the functional syndrome is useful to include amongst other conditions attentional dyslexia and neglect dyslexia. The variety of sub-forms would correspond to the behavioural effects of the different ways in which the orthographic processing systems can be impaired. What distinguishes the broader form from pure alexia is that the patient lacks the capacity to use a serial letter processing strategy, and so interpretation of visual dyslexia in terms of the impairment to the orthographic processing systems is not contaminated by the use of a compensatory strategy that results in processing operations which are qualitatively very different from the normal and highly opaque. The lack of a serial letter processing strategy makes visual dyslexia a much more transparent functional syndrome.

A music quality rating test battery for cochlear implant users to compare the FSP and HDCIS strategies for music appreciation

Abstract

Objective: The purpose of this study was to develop a music quality rating test battery (MQRTB) and pilot test it by comparing appraisal ratings from cochlear implant (CI) recipients using the fine-structure processing (FSP) and high-definition continuous interleaved sampling (HDCIS) speech processing strategies. Design: The development of the MQRTB involved three stages: (1) Selection of test items for the MQRTB; (2) Verification of its length and complexity with normally-hearing individuals; and (3) Pilot testing with CI recipients. Study Sample: Part 1 involved 65 adult listeners, Part 2 involved 10 normally-hearing adults, and Part 3 involved five adult MED-EL CI recipients. Results: The MQRTB consisted of ten songs, with ratings made on scales assessing pleasantness, naturalness, richness, fullness, sharpness, and roughness. Results of the pilot study, which compared FSP and HDCIS for music, indicated that acclimatization to a strategy had a significant effect on ratings (p < 0.05). When acclimatized to FSP, the group rated FSP as closer to ‘exactly as I want it to sound’ than HDCIS (p < 0.05), and that HDCIS sounded significantly sharper and rougher than FSP. However when acclimatized to HDCIS, there were no significant differences between ratings. There was no effect of song familiarity or genre on ratings. Conclusions: Overall the results suggest that the use of FSP as the default strategy for MED-EL recipients would have a positive effect on music appreciation, and that the MQRTB is an effective tool for assessing music sound quality.

Sumario

Objetivo: El propósito de este estudio fue desarrollar una batería de pruebas de clasificación de la calidad musical (MQRTB) y hacer una prueba piloto comparando los índices de valoración de usuarios de implante coclear (CI) con el uso de dos estrategias de procesamiento del lenguaje: la de Procesamiento de Estructuras Finas (FSP) y la de Muestras Intercaladas continuas de Alta Definición (Continua) (HDCIS). Diseño: El desarrollo de la Batería MQRTB comprendió tres etapas: (1) Selección de ítems de prueba para la MQRTB; (2) Verificación de su extensión y complejidad con individuos normoyentes; y (3) Prueba Piloto con usuarios de CI. Muestra de Estudio: Parte 1: comprendió 65 escuchas adultos; Parte 2: comprendió a 10 adultos normoyentes y Parte 3: comprendió a 5 adultos, usuarios de CI MED-EL. Resultados: El MQRTB consistió en 10 canciones, para las cuales se establecieron escalas con sus índices de agrado, naturalidad, plenitud, precisión y aspereza. Los resultados del estudio piloto los cuales compararon FSP y HDCIS para música, indicaron que la aclimatación a una estrategia tenía un efecto significativo en las evaluaciones (p < 0.05). Con aclimatación a FSP, el grupo clasificó la FSP mas cerca a lo que ‘exactamente quiero que suene’ que con HDCIS (p < 0.05), y que la HDCIS sonaba significativamente más precisa y áspera que la FSP. No obstante, con aclimatación a HDCIS, no existieron diferencias significativas en las evaluaciones. No hubo ningún efecto en las evaluaciones a partir de la familiaridad de la canción o a partir del género. Conclusiones: Globalmente, los resultados sugieren que el uso de FSP como estrategia sin otras alternativas, para los usuarios de MED-EL, puede tener un efecto positivo en la apreciación de la música y que la MQRTB es una herramienta efectiva para evaluar la calidad de los sonidos musicales.
