Genetic Accommodation

Abstract Heyes argues that human metacognitive strategies (cognitive gadgets) evolved through cultural rather than genetic evolution. Although we agree that increased plasticity is the hallmark of human metacognition, we suggest cognitive malleability required the genetic accommodation of gadget-specific processes that enhanced the overall cognitive flexibility of humans.

Abstract. Some people, although they are perfectly healthy and happy, cannot enjoy music. These individuals have musical anhedonia, a condition which can be congenital or may occur after focal brain damage. To date, only a few cases of acquired musical anhedonia have been reported in the literature with lesions of the temporo-parietal cortex being particularly important. Even less literature exists on congenital musical anhedonia, in which impaired connectivity of temporal brain regions with the Nucleus accumbens is implicated. Nonetheless, there is no precise information on the prevalence, causes or exact localization of both congenital and acquired musical anhedonia. However, the frequent involvement of temporo-parietal brain regions in neurological disorders such as stroke suggest the possibility of a high prevalence of this disorder, which leads to a considerable reduction in the quality of life.
