As Linkadge pointed out, the abstract does not suggest psychostimulants act primarily on dopamine D4 receptors. Rather, the article is a review of the role of DA D4-receptors in psychostimulant addiction.
Stimulants are indirect dopamine agonists that do not target any particular receptor directly, but they increase synaptic dopamine, which in turn acts on the full range of DA receptors. If there is a receptor they act "primarily" on, it would be D2 simply because that is the most common DA receptor.
