Intellectual blocks result in an inefficient choice of mental tactics or a shortage of intellectual ammunition.
Expressive blocks inhibit your vital ability to communicate ideas-not only to others, but to yourself as well.
1) Solving the problem using an incorrect language
Choice of the problem-solving language is difficult not only because the choice is usually made unconsciously, but also because of the heavy emphasis on verbal thinking (with matematical thinking a poor second).
2) Inflexible or inadequate use of intellectual probem-solving strategies
3) Lack of, or incorrect, information
4) Inadequate language skill to express or record ideas
