AP PSYCHOLOGY

Detailed explanation-1: -Restricted/repetitive behaviors is a core diagnostic criterion for autism. Motor repetitions, referred to as “lower-order, ” include self-stimulation, hand flapping, twirling, repeating phrases, manipulating objects, banging toys together, and repeatedly pushing buttons (1).

Detailed explanation-2: -People who are distressed by recurring, unwanted, and uncontrollable thoughts or who feel driven to repeat specific behaviors may have obsessive-compulsive disorder (OCD). The thoughts and behaviors that characterize OCD can interfere with daily life, but treatment can help people manage their symptoms.

Detailed explanation-3: -Repetitive behaviour may include arm or hand-flapping, finger-flicking, rocking, jumping, spinning or twirling, head-banging and complex body movements. This is known as ‘stimming’ or self-stimulating behaviour. The reasons behind it include: for enjoyment.

Detailed explanation-4: -Various brain regions and pathways govern repetitive behaviors; however, the most notable pathway is the cortico-basal ganglia-thalamic pathway (Fig. 1a), which is also involved in the motor activities [42, 43].
