includes the following 5 in-depth Ideas Roadshow Conversations featuring leading researchers. This collection includes a detailed preface highlighting the connections between the different books. Each book is broken into chapters with a detailed introduction and questions for discussion at the end of each chapter: Ellen Bialystok is a world-leading expert on the effects of bilingualism on cognitive processes across our lifespan. This conversation examines how Ellen discovered differences in the development of essential cognitive and language abilities for bilingual children, the use of different brain networks by monolingual and bilingual young adults performing simple conflict tasks, and the postponement of symptoms of dementia in bilingual older adults, and many more fascinating aspects of bilingualism. This conversation explores Victor Ferreira's research which is focused on language production, especially with regard to grammar, lexical structure and speaker-hearer interaction, and his interests to incorporate computational and quantitative modelling of cognitive processing. Topics that are examined in this extensive conversation are what autism actually is, the reasons behind the increased number of diagnoses over the last few years, autism spectrum disorders, Asperger's syndrome, mentalizing, brain imaging to research the cognitive and neurobiological bases of autism and much more. This conversation examines Greg Hickok's neuroscience research related to speech and language which led him to eventually reject many aspects of the mirror neuron hypothesis, while giving his views on the mechanisms behind imitation and what mirror neurons really do. This conversation examines Martin Monti's innovative work with patients who are in a vegetative state or minimally conscious state which has led to some surprising results that might well prove to be integral to our development of a deeper understanding of consciousness.
