“…At first glance, this result is surprising because it suggests a possible overlap between language control and nonverbal control mechanisms not observed in AMBA; however, upon closer inspection, it appears that it might capture the multi-step process intrinsic to the language control task. Managing semantic processes and language comprehension activates language centers, as well as areas responsible for domain general cognitive processing [89][90][91]. There is evidence that in addition to language processing, the left inferior frontal gyrus is recruited to complete semantically ambiguous tasks [92] and verbal and nonverbal cognitive tasks [93], including task selection [94], suggesting that that it is connected to a domain general cognitive network.…”

The purpose of this study was to examine the relationship between language control, semantic control, and nonverbal control in bilingual aphasia. Twelve bilingual adults with aphasia (BPWA) and 20 age-matched bilingual adults (AMBA) completed a language control task, semantic control task, and nonverbal control task, each designed to examine resistance to distractor interference. AMBA and BPWA exhibited significant effects of control on all tasks. To examine efficiency of control, conflict magnitudes for each task and group were analyzed. Findings revealed that AMBA exhibited larger conflict magnitudes on the semantic control task and nonverbal control task compared to the language control task, whereas BPWA exhibited no difference in conflict magnitudes between the language control task and semantic control task. Further analysis revealed that BPWA semantic control conflict magnitude was smaller than AMBA semantic control conflict magnitude. Taken together, these findings suggest that BPWA present with diminished effects of semantic control. In the final analysis, conflict magnitudes across tasks were correlated. For AMBA, semantic control and nonverbal control conflict magnitudes were significantly correlated, suggesting that these two types of control are related. For BPWA, language control and nonverbal control conflict magnitudes were significantly correlated; however, this finding may capture effects of domain general cognitive control as a function of increased cognitive load, rather than domain general cognitive control as a function of language control.

“…Este supuesto también podría relacionarse con el bajo desempeño que presentó el paciente en algunas subpruebas de lenguaje, es decir, que las dificultades en este dominio podrían deberse a la complejidad del estímulo presentado (que aumentan la carga cognitiva). El análisis presentado por Tesak (1994), sobre los efectos de la carga cognitiva en tareas de lenguaje en pacientes afásicos, apunta a que, semejante a lo encontrado en el paciente del presente estudio, el éxito en las actividades más simples y la falla en las más complejas puede ser un problema computacional más que estructural (o de la condición de base de los pacientes).…”

Evaluación neuropsicológica de un adulto colombiano diagnosticado con Síndrome de Morquio B

El síndrome de Morquio B es una enfermedad rara y de baja prevalencia, por lo cual poco se ha estudiado so- bre el funcionamiento neuropsicológico y estado cognitivo de quienes lo padecen. Este estudio de caso presenta los resultados del funcionamiento en atención, memoria, lenguaje, gnosias, praxias y funciones ejecutivas de un adulto co- lombiano diagnosticado con este síndrome. Se encontró que el paciente puede adquirir nuevo conocimiento; muestra memoria visoespacial y de trabajo verbal conservadas; repite, lee y escribe información sencilla que es conocida para él; sigue órdenes simples a partir de comandos verbales; muestra habilidades visoperceptuales y grafomotoras; tiene un desarrollo normal de pensamiento abstracto y asociativo, y es capaz de planear y solucionar problemas. Sin embargo, presenta dificultades en atención visual sostenida, atención audio-verbal, velocidad de procesamiento, lenguaje comprensivo, repetición y escritura al dictado de frases completas, flexibilidad cognitiva, y fluidez verbal semántica y fonológica. Se discute como factores más relevantes del funcionamiento cognitivo del paciente la relación entre el síndrome de Morquio B y la gangliosidosis GM1, y la falta de entrenamiento en el manejo de información de alta complejidad, dada su condición de desescolarización. Palabras clave: Síndrome de Morquio B, MPS IV-B, enfermedades raras, evaluación neuropsicológica, mucopolisacaridosis

Innateness, autonomy, universality? Neurobiological approaches to language

The concepts of the innateness, universality, species-specificity, and autonomy of the human language capacity have had an extreme impact on the psycholinguistic debate for over thirty years. These concepts are evaluated from several neurobiological perspectives, with an emphasis on the emergence of language and its decay due to brain lesion and progressive brain disease.Evidence of perceptuomotor homologies and preadaptations for human language in nonhuman primates suggests a gradual emergence of language during hominid evolution. Regarding ontogeny, the innate component of language capacity is likely to be polygenic and shared with other developmental domains. Dissociations between verbal and nonverbal development are probably rooted in the perceptuomotor specializations of neural substrates rather than the autonomy of a grammar module. Aphasiologicaldata often assumed to suggest modular linguistic subsystems can be accounted for in terms of a neurofunctional model incorporating perceptuomotor-based regional specializationsand distributivity of representations. Thus, dissociations between grammatical functors and content words are due to different conditions of acquisition and resulting differences in neural representation. Human brains are characterized by multifactorial interindividual variability, and strict universality of functional organization is biologically unrealistic.A theoretical alternative is proposed according to which (1) linguistic specialization of brain areas is due to epigenetic and probabilistic maturational events, not to genetic ”hard-wiring,” and (2) linguistic knowledge is neurally represented in distributed cell assemblies whose topography reflects the perceptuomotor modalities involved in the acquisition and use of a given item of knowledge.
