Some researchers in this field posit that positive psychology can be delineated into three overlapping areas of research:

Some researchers posit environments of ammonia, or more likely water-ammonia mixtures.

Some researchers posit that there are at least three forms of alpha waves, which may all have different functions in the wake-sleep cycle.

Other researchers at the Mayo Clinic posit that all activity that is not sleeping, eating, or sports activity still contributes to overall health.

A few researchers have posited that the positive effects of reminiscence therapy are the result of increased coping skills.

Some researchers, such as Alex Comfort, posit three potential advantages of sexual intercourse in humans, which are not mutually exclusive: reproductive, relational, and recreational.

However, other researchers posit that these symbols are divinity identifiers, decorations, or generic symbols, rather than signs of a writing system.

Psychologists, researchers, and other authors have posited a number of possible explanations for the belief that some can provide valuable crime information from psychic abilities.

For example, these researchers posited that people defend themselves by altering their fear responses from uncertainty to an enthusiasm approach.

Some researchers posit that Sehnsucht has a developmental function that involves life management.
