El Banco Interamericano de Desarrollo (BID) y la Fundación INECO se unieron para dar vida a la primera Red Latinoamericana de Conducta Humana y Políticas Públicas. Se trata de un grupo multidisciplinario de expertos que asesorará a los gobiernos de la región, con el principal objetivo de alcanzar impacto social a través de políticas que conlleven una comprensión más realista de la conducta humana.

ABSTRACT This study examined whether systematic whole-body stimulation and increased attention to visuospatial motion patterns can enhance the appraisal of action meanings evoked by naturalistic texts. Participants listened to action and neutral (non-action) narratives before and after videogame-based bodily training, and responded to questions on information realized by verbs (denoting abstract and action processes) and circumstances (conveying locative or temporal details, for example). Strategically, we worked with dyslexic children, whose potential comprehension deficits could give room to post-training improvements. Results showed a selective boost in understanding of action information, even when controlling for baseline performance. Also, this effect proved uninfluenced by short-term memory skills, and it was absent when training relied on non-action videogames requiring minimal bodily engagement. Of note, the movements described in the texts did not match those performed by participants, suggesting that well-established effector- and direction-specific language embodiment effects may be accompanied by more coarse-grained sensorimotor resonance, driven by activation of motor and visuospatial sensory systems. In sum, the stimulation of movement-related mechanisms seems to selectively boost the appraisal of actions evoked by naturalistic texts. By demonstrating such links between two real-life activities, our study offers an empirical tie between embodied and situated accounts of cognition.
RESUMEN En este trabajo, evaluamos si la estimulación corporal ecológica puede mejorar la comprensión de acciones en textos naturalistas. Primero, 20 niños con dislexia realizaron pruebas de comprensión de narraciones con alto y bajo contenido motor. Luego, se estimuló su sistema motor mediante videojuegos dinámicos en la consola Nintendo Wii. Al evaluárselos nuevamente con otro par de textos, se observó una mejoría específica en su comprensión de acciones. Este efecto no se debió a un incremento en memoria de trabajo y tampoco surgió ante videojuegos que no requieren actividad corporal. Así, éste es el primer estudio en demostrar que la actividad corporal sistemática puede mejorar la comprensión de acciones en historias narrativas.

ABSTRACT The linguistic profile of Parkinson’s disease (PD) is characterized by difficulties in processing units which denote bodily movements. However, the available evidence has low ecological validity, as it stems from atomistic tasks which are never encountered in real life. Here, we assessed whether such deficits also occur for meanings evoked by context-rich narratives, considering patients with and without mild cognitive impairment (PD-MCI and PD-nMCI, respectively) and matched controls for each group. Participants read two naturalistic stories (an action text and a neutral text) and responded to questions tapping the appraisal of verb-related and circumstantial information. In PD-MCI, impairments in the appraisal of action meanings emerged alongside difficulties in other categories, but they were unique in their independence from general cognitive dysfunction. However, in PD-nMCI, deficits were observed only for action meanings, irrespective of the patients’ domain-general skills (executive functions and general cognitive state). Also, using multiple group discriminant function analyses, we found that appraisal of action meanings was the only discourse-level variable that robustly contributed to classifying PD-MCI patients from controls (with an accuracy of 88% for all participants and for each sample separately). Moreover, this variable actually superseded a sensitive executive battery in discriminating between PD-nMCI and controls (with a combined accuracy of 83% for all participants, correctly classifying 79.2% of patients and 87.5% of controls). In sum, action appraisal deficits seem to constitute both a hallmark of naturalistic discourse processing in PD and a sensitive subject-level marker for patients with and without MCI. Such findings highlight the relevance of ecological measures of embodied cognitive functions in the assessment of this population.
RESUMEN En este estudio, basado en un nuevo protocolo de lectura de textos narrativos, evaluamos la aprehensión de acciones en la enfermedad de Parkinson, considerando pacientes con y sin deterioro cognitivo leve (EP-DCL y EP-nDCL). Los pacientes con EP-DCL presentaron déficits en distintas categorías textuales, pero sólo la aprehensión de acciones resultó independiente de sus habilidades cognitivas generales. Los pacientes EP-nDCL sólo manifestaron déficits en dicha categoría. Además, esta variable permitió clasificar a más del 80% de los pacientes, lo cual sugiere que el procesamiento de acciones en textos naturalistas podría constituir un marcador robusto de esta enfermedad.
