Coder's block is a good way to describe it.

I've had phone interviews where I've been asked to solve a logic puzzle with pen/paper while explaining my approach. Solving a problem you've never thought about while being put on the spot turns out to be incredibly difficult. These sorts of problems require deep concentration and quiet yet it tends to be awkward to have silence between strangers. The situation really inhibits serious problem solving.
