Conceptual blockbusting--chap5 Intellectual and Expressive blocks

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
