“…Surprisingly, the majority of studies report similar, or higher, pleasantness ratings in depressed patients compared to controls in response to sweet solutions (Amsterdam et al, 1987;Berlin et al, 1998;Scinska et al, 2004;Swiecicki et al, 2009;Dichter et al, 2010) and various odors (Steiner et al, 1993;Pause et al, 2001;Lombion-Pouthier et al, 2006;Scinska et al, 2008;Clepce et al, 2010). Similarly, evidence from studies of patients suffering from schizophrenia does not suggest that this patient group experiences lower levels of hedonic reactivity to pleasurable stimuli compared with controls (Heerey and Gold, 2007;Barch and Dowd, 2010;Strauss and Gold, 2012).…”
