There’s a reason why politicians sometimes find it hard to talk. Rick Perry’s failure to remember the name of one of the federal agencies he would abolish if elected president, namely the Department of Energy, was most likely an example of a very common phenomenon called "Tip of the Tongue" phenomenon or TOT."

The majority of naturally occurring TOT states are linked to proper names and the likelihood of finding oneself in such a state increases as we get older. "
