It can be verbal (speech patterns, physical activity while speaking, or the tone of voice of an individual)[1][2] or it can be non-verbal (facial expressions and body language[2]).
Some psychologists instead use the term honest signals because such cues are involuntary behaviors that often convey emotion whereas body language can be controlled.
For example, the unconscious mind sometimes picks up on and relates non-verbal cues about an individual based on how they have arranged their settings such as their home or place of work.
Not much is known about the unconscious mind but it is believed to contain the biological instincts that humans act on every day, such as sex and aggression.
It includes many mental activities such as thinking, calculating, planning, talking to one's self, internal monologue, and day-dreaming.
Additionally, the manner of phrasing sentences and selection of words that the brain subconsciously generates are used as well to regulate other peoples emotions.
