How Do Cultural Numerical Concepts Build Upon an Evolved Number Sense?
نویسنده
چکیده
Several authors (e.g. Dehaene, 1997) have proposed that mathematical concepts build upon an evolved innate number sense, which we share with many other species. However, they have left unspecified how these mathematical concepts can come into existence and how they are transmitted. Models of content biased cultural transmission (e.g. Boyer, 2001) predict that cultural traits that bear a close fit to or a strong violation of intuitions provided by evolved cognitive mechanisms (modules) will be more widespread than others. Here, I adopt a similar approach to explain the emergence and spread of two mathematical concepts: positive integers, which have emerged independently in many cultures, and zero, which has evolved only once as a true numerical concept, but has successfully spread to other cultures. I will argue that these patterns of emergence and transmission lie in their fit with or their violation of intuitions provided by our evolved number sense.

Our Sense of Identity: “Who am I?” Gender and Cultural Studies
Identity is seen as a cultural and social construct, which indicates how we have been embodied and how we might represent ourselves. The knowledge that identities are the outputs of discourses is a familiar characteristic of some societal concepts. Gender, as an identity or a sense of our identity we build for ourselves, rather than something we are born with, is a constructed cultural category...

Our ancestors without fear, worry and anxiety are not our ancestors, as organisms without defense systems were extinct. Therefore, while behavior such as fear and anxiety are useful to prevent harm, the exaggerated form, that is, anxiety disorders, has more costs than benefits. Likewise, while a panic attack is a normal and useful response in the face of life-threatening danger, a panic disorde...

متن کاملAn Approach to Nonlocal, Nonlinear Advection
We describe an approach to nonlocal, nonlinear advection in one dimension that extends the usual pointwise concepts to account for nonlocal contributions to the flux. The spatially nonlocal operators we consider do not involve derivatives. Instead, the spatial operator involves an integral that, in a distributional sense, reduces to a conventional nonlinear advective operator. In particular, we...
