Thought deceleration

Thought deceleration (also known as bradyphrenia)[1] is the process of thought being slowed down significantly in comparison to that of normal sobriety. When experiencing this effect, it will feel as if the time it takes to think a thought and the amount of time which occurs between each thought has been slowed down to the point of greatly impairing cognitive processes. It can manifest itself in delayed recognition, slower reaction times, and fine motor skills deficits.

Thought deceleration is often accompanied by other coinciding effects such as analysis suppression and sedation in a manner which not only decreases the person's speed of thought, but also significantly decreases the sharpness of a person's mental clarity. It is most commonly induced under the influence of heavy dosages of depressant compounds, such as GABAergics[2][3][4], antipsychotics[5], and opioids[6][7][8]. However, it can also occur to a lesser extent under the influence of heavy dosages of hallucinogens such as psychedelics[9], dissociatives[10], deliriants[4][11], and cannabinoids[12][13][14][15].
