The Extended Mind Hypothesis

The idea that we use pieces of our external environment to aid in our cognitive abilities has always been visible yet has remained somewhat ignored as our computational processes were always considered to be circumscribed to those that transpire under skin and skull in the biological brain. Then in 1998 Andy Clark and David Chalmers proposed a radical new form of externalism called the Extended Mind Hypothesis. Referred to as active externalism because of the active role the environment plays in driving cognitive processes it came under attack from a number of angles.

Cocaine Causes Dopamine Reuptake In Crickets To Be Blocked

This article was written with the help of Macquarie University and relevant staff who assisted in providing the apparatus, methods etc. for the data collection.

Abstract
In an attempt to examine the effects of cocaine on dopamine and horizontal locomotor activity, an experiment was conducted on Acheta domestica (crickets). In a double-blind design 121 crickets were randomly assigned to groups before baseline data collection commence. After which, they were then injected with either cocaine or saline only (vehicle). In both the pre and post-treatment timeframes horizontal locomotor activity was measured for twenty minutes. Statistically significant results were found to exist between the saline and cocaine groups, with the cocaine group displaying a much higher amount of horizontal locomotor activity than their counterparts. These results suggest, as is supported by other evidence, that cocaine blocks the Dopamine Transporter.
