Different types of perceptual blocks

* Perceptual Blocks. These are obstacles that prevent us from clearly perceiving the problem or the information needed to solve it. A few perceptual blocks are: * Stereotyping:- This assumes that once an item or idea is identified it can have no other use or function. * Imaginary boundaries:- We project boundaries on the problem and solution that need not exist in reality. * Information overload:- Trying to satisfy an excess of information and detail restricts the alternative that can be considered. from http://http-server.carleton.ca/~gkardos/88403/CREAT/Block4.html here is some helpful linksfrom my search through ask.com: http://ask.reference.com/web?q=Perceptual%20Blocks%20&l=dir&qsrc=2891&o=100043
