Psychologically, What Causes You To Do Something Wrong Repeatedly?

Example: I am fairly fast and accurate at typing. I am typing a study guide for my psychology class and am on the chapter about the nervous system. Every time I type the word system, I leave out the second ‘s’, regardless of how hard I try to type it correctly. I understand this example is trivial; however, having the same typing error on the same word got annoying and made me question the cause. So, What causes this type of “mental block” and is there a name for it? P.S. Please only respond if you have a serious, psychologically based answer.

5. Name the three parts of the vascular system of plants.
6. Energy ________________ (increases or decreases) as an organism eats a plant.
The Animal Kingdom
Animals are all multicellular with eukaryote type cells. Animals do NOT have a cell wall. They are also heterotrophic and must ingest their food.
1. Insects do not have a backbone.
2. _______________ are a group of animals that do contain a backbone. Mammals are examples of animals with a backbone.
3. _______________ is a term used to describe animals that can NOT control their body temperature internally. They must get into the sun to be warm and in the shade to be cool. Amphibians are examples.
4. ______________is a term used to describe animals that can control their body temperature internally. Humans are an example.
