“…Spontaneous speech is often used to validate different neuropsychiatric attributes (11)(12)(13)(14)(15)(16) . But if multiple items representative of spontaneous speech are used, and it is also observed that the patient presents, for example, aphasia, subjecting him/her to the same failure over and over again can be harmful.…”

“…Within this framework, many psychological attributes are evaluated or validated on the basis of spontaneous speech (11)(12)(13)(14)(15)(16)(17)(18)(19) , considered as a key attribute. However, there are few studies on the validity of spontaneous speech itself, in particular, on how it is perceived by caregivers in adults with acute aphasia.…”

RESUMEN Objetivo Estudiar la relación entre la percepción del cuidador sobre el deterioro en el habla espontánea del paciente, según un ítem de cuatro preguntas administradas mediante entrevista semiestructurada, y el desempeño del paciente en la Evaluación Breve de la Afasia (EBA). Método Se examinaron 102 pacientes diestros, con lesiones cerebrales focales de diferente tipo y localización. EBA es un instrumento válido y confiable para la medida de la afasia. Se correlacionó la percepción del cuidador con el ítem de habla espontánea, la puntuación total y los tres principales factores de EBA: el factor de Expresión, el de Comprensión y el Complementario. Se analizó la precisión (sensibilidad-especificidad) de la percepción del cuidador sobre el habla espontánea del paciente, respecto de la presencia o ausencia de trastorno, según el profesional, en el ítem de habla espontánea de EBA. Resultados La correlación estudiada fue satisfactoria, siendo mayor (superior al 80%) para los siguientes indicadores: el ítem de habla espontánea, el factor de Expresión y la puntuación total de la escala; la correlación fue un poco menor (superior al 70%) para el factor de Comprensión y el Complementario. Comparando dos puntos de corte que evaluaron la precisión en la percepción del cuidador, se observaron resultados satisfactorios en términos de sensibilidad y especificidad (>70%), con cocientes de probabilidad superiores a 3. Usando la mediana como punto de corte, se obtuvieron discriminaciones diagnósticas más satisfactorias. Conclusión Entrevistar al cuidador específicamente sobre el habla espontánea del paciente, en forma abreviada, proporciona información relevante para el diagnóstico de la afasia.

“…The PFC appears to support organizational and coherence functions in cognition and, more specifically, in communication as successive utterances are woven together to create a narrative (Silbert, Honey, Simony, Poeppel, & Hasson, 2014;Troiani et al, 2008). Similarly, mentalizing (perceiving and interpreting others' behavior as part of their intentional mental states) and the construction of situational models in discourse (e.g., context, chronology) are reliant on PFC activity (AbdulSabur et al, 2014). In addition, PFC networks are involved in coarse semantic processing (predominantly right temporal), coherence monitoring (dorsolateral prefrontal), text PFC in Discourse: An fNIRS Study 67 integration (left-frontotemporal), character perspective monitoring (e.g., theory of mind; medial frontal), and spatial imagery (interparietal sulcus; Mason & Just, 2006).…”

“…However, it is at the level of discourse where the pragmatic properties of language naturally emerge and where language systems and cognitive processes, such as organizational schemas, are likely to interact (AbdulSabur et al, 2014). The present study is an exploratory, quantitative, observational study of brain function during naturalistic discourse processing and production in non-brain-injured adults.…”

“…Most scientific studies of language over the past 50 years have taken the form of investigations at the levels of words and single sentences (AbdulSabur et al, 2014). However, it is at the level of discourse where the pragmatic properties of language naturally emerge and where language systems and cognitive processes, such as organizational schemas, are likely to interact (AbdulSabur et al, 2014).…”

Discourse is a commonly occurring and cognitively demanding form of naturalistic communication (e.g., conversation, event narration, personal and fictional narratives, text reading/generation). Because of the prevalence of these communication acts in daily routines (e.g., educational, vocational, and social), disrupted discourse is an important target for treatment of persons with cognitivecommunication (CC) disorders (American Speech-Language Hearing Association, 2005). However, there is a paucity of information with regard to the underlying cognitive architecture and processing demands associated with the various forms of discourse in non-brain-injured adults. This is, in part, due to a number of methodological constraints of functional neuroimaging technologies such as functional magnetic resonance imaging that severely limit ecologically typical communication acts such as listening and speaking during scanning. To circumvent these issues, this pilot investigation used functional near infrared spectroscopy (fNIRS) to monitor hemodynamic activity in the prefrontal cortex (PFC) during natural discourse-processing tasks in 13 neurologically healthy adult participants. Task demands were manipulated across a variety of discourse types to elucidate the associated neural and cognitive resources. Results indicate that the comprehension of well-organized discourse text is minimally demanding on the PFC. However, discourse production places a significant burden on the PFC and these processing demands generally reflect the relative complexity of the discourse task. These findings are discussed in terms of potential clinically relevant implications with regard to the elicitation, assessment, and remediation of CC impairments in clinical populations. Key words: brain injury, cognitive-communicative disorders, cortical activity, discourse, functional near infrared spectroscopy, speech-language pathology DISCOURSE AND NEUROIMAGINGDiscourse is a cognitively demanding form of naturalistic communication, commonly utilized in daily activities across ed-
