Psychological harassment
This is humiliating or abusive behaviour that lowers a person’s self-esteem or causes them torment. This can take the form of verbal comments, actions or gestures. Falling into this category is workplace mobbing. Community Based Harassment — stalking by a group against an individual using repeated distractions that the individual is sensitized to, such as clicking an ink pen.

Racial harassment
The targeting of an individual because of their race or ethnicity. The harassment may include words, deeds, and actions that are specifically designed to make the target feel degraded due to their race or ethnicity.

Typically the targeted individual is a subordinate, for example, a fraternity pledge, a first-year military cadet, or somebody who is considered 'inferior' or an 'outsider'.
