The normal resting adult human heart rate ranges from 60â100 bpm. Tachycardia is a fast heart rate, defined as above 100 bpm at rest. Bradycardia is a slow heart rate, defined as below 60 bpm at rest.During sleep a slow heartbeat with rates around 40â50 BPM is common and is considered normal.When the heart is not beating in a regular pattern, this is referred to as an arrhythmia.These abnormalities of heart rate sometimes indicate disease.radycardia is a slow heart rate, defined as below 60 bpm at rest.

Shaping is a conditioning paradigm used primarily in the experimental analysis of behavior. The method used is differential reinforcement of successive approximations.It was introduced by B.F. Skinner with pigeons and extended to dogs, dolphins, humans and other species.n shaping, the form of an existing response is gradually changed across successive trials towards a desired target behavior by rewarding exact segments of behavior.
A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture or material composition. Psychologists have theorized that humans mentally break down images into simple geometric shapes called geons. Examples of geons include cones and spheres.
