What is the term used for behaviors that are problematic due to their infrequency?

The term that describes behaviors that are problematic due to their infrequency is behavioral deficits. This concept refers to a lack or shortage of certain behaviors that are necessary for an individual's functioning or development in various contexts. For instance, a child may lack social skills, which can lead to difficulties in forming relationships with peers. Recognizing these deficits is crucial in behavior analysis, as it helps practitioners identify areas that require intervention and support to enhance the individual's functioning.

Behavioral excesses, on the other hand, relate to overly frequent behaviors that may also cause concern but do not pertain to infrequent behaviors. The other terms, behavioral issues and behavioral patterns, are broader and less specific, making them less precise in identifying the concept of infrequency in problematic behaviors.
