also shown adolescents to be less sensitive to the aversive effects of tetrahydrocannnabinol (THC), one of the major cannabinoids in marijuana (Schramm-Sapyta et al., 2007), while being more sensitive to cannabinoid-induced disruptions in cognitive performance (Cha et al., 2006). A propensity for adolescents to be more sensitive to the rewarding properties of certain natural stimuli, including novelty (Douglas et al., 2003) and social conspecifics (Douglas et al., 2004), has been reported as well. Moreover, when assessing oral reactivity as an index of hedonic affect to taste stimuli, adolescents have been reported to exhibit not only greater positive taste responses to palatable sucrose solutions but also reduced negative taste reactions to the aversive taste of quinine (Wilmouth & Spear, 2009).
