Do not reduce your hot end temperature to solve this issue. As mentioned it is a temperature problem - or more accurately a cooling issue. PLA takes a few seconds to set after it is extruded, and so if you extrude the next layer immediately on top of one just printed, you will get deformation. You need to provide the time for proper cooling. Most slicers offer some ways of handling this.
As mentioned, most slicers allow you to specify a minimum layer time. If a layer will be less than this time, the slicer will automatically slow things down so that the just-printed layer can solidify before going on to the next layer. Of course the problem with this approach is that the hot end itself remains close to the printed object. Still, it remains one of the better techniques for this issue.
Skeinforge, and perhaps other slicers, offered a cooling strategy called orbit where it would move the hot end away from the printed object and basically move in circles for a few seconds. The problem with this is that your hot end can ooze during this time.
A third technique - and one that's not implemented by the slicer - is to just print multiple objects. Just adding a second object, as part of the same print job, can be a simple way to solve this issue. Usually this problem only happens on small objects anyways, so it's not too wasteful of filament.
