Perspectiva Narrativa sobre HISTORIA DEL TIEMPO, de Stephen Hawking
Cognition in Mathematics, Science, & Technology eJournal 11/2010; 2(19). DOI:10.2139/ssrn.1707364
Reseña con resumen y comentario de HISTORIA DEL TIEMPO, de Stephen Hawking, sintetizando las tesis principales del libro y evaluándolas desde el punto de vista de una filosofía del tiempo (tanto cósmico como humano) informada por la teoría narrativa y la filosofía evolucionista. Cualquier historia o teoría del tiempo, por compleja que sea, ha de volverse más complicada una vez se tiene en cuenta el papel de las descripciones, modelos y teorías en tanto que instrumentos cognitivos históricamente situados. El lenguaje intencionalista de Hawking a la hora de describir el "diseño cósmico" también se somete a crítica.

ABSTRACT - This is a review and commentary of Stephen Hawking's A Brief History of Time, summarizing some of the book's main tenets and evaluating them from the standpoint of a philosophy of time (both cosmic and human) informed by narrative theory and by evolutionary philosophy. Any account of time, however complex, is further complicated once the role of descriptions as historically situated cognitive instruments is taken into account. Hawking's intentionalist discourse as regards cosmic design is also criticized.

What Makes us Human?
En este programa de la BBC (2012-13) está parte de la respuesta a esta pregunta que nos hacíamos en mayo de 2012: Qué gen buscar, cuál es el gen cuya mutación ha potenciado la conectividad de las neuronas, que es la clave para el pensamiento humano. Lo que posibilita la sintaxis, las herramientas complejas, y las fusiones conceptuales. Véase...
The Mirror Phase and Mirror Neurons
The Mirror phase and Mirror Neurons (video).
The ability to recognize oneself in a mirror, once considered a uniquely human attribute, is shared by great apes, dolphins, elephants and magpies. Diana Reiss (Hunter College, CUNY) discusses comparative studies of mirror self-recognition in dolphins and elephants, which show striking similarities to humans and great apes in regard to their behavior when exposed to a mirror.

La voz interior
Una conferencia que explica ciertos efectos de la atención para la activación de centros motores de producción lingüística en los circuitos cerebrales asociados a la verbalización y al almacenamiento léxico. También dice cosas interesantes para explicar las voces que algunas personas oyen dentro de su cabeza—aquello de Pink Floyd de "there's someone in my head but it's not me" (The Dark Side of the Moon).
Inner speech in action : EMG data during verbal thought and auditory verbal hallucination
Conférence de Hélène Loevenbruck.
Inner speech refers to the silent production of words in one’s mind. It plays a central role in human consciousness at the interplay of language and thought and it has been described as a kind of motor action. An influential motor control model (the ‘predictive model’) claims that when motor commands are sent to the motor system to achieve an intended state, an efference copy is issued in parallel. This efference copy is used to calculate a prediction of the sensory outcome of the motor plan. It is suggested that if the actual sensory feedback matches the predicted outcome then self-authorship is experienced. This model has been extended to inner speech and it has been suggested that a defective efference copy could underlie auditory verbal hallucinations (AVH) in schizophrenia, with self-initiated covert verbal actions experienced as originating from an external cause. In this talk, I will present labial EMG data that suggest that wilful inner speech can be regarded as a kind of action and AVHs as disrupted inner speech.
