Mographic Variables Various research have failed to discover 1479-5868-9-35 important relationships amongst N value (respondents)] Answer option [n ( )] Not typically (score 1?) Normally (score schizophrenia symptom severity and EBC dependent variables (61, 63, 68). Brown and colleagues (61) and Bolbecker and colleagues (63) also reported null final results involving symptom severity and extinction dependent variables. Parker and colleagues (66) found no considerable correlations amongst good or negative symptoms along with the three phases of conditioning the authors usedcontrols (63, 64), although 3 other studies reported no considerable differences among groups (61, 65, 67). Ultimately, with regard to UR amplitude, 3 research reported improved UR amplitude in schizophrenia vs. controls (63, 65, 67), whereas 3 research reported no substantial group distinction (61, 62, 64).Frontiers in Psychiatry | http://www.frontiersin.orgDecember 2015 | Volume 6 | ArticleFrontiers in Psychiatry | http://www.frontiersin.org 6 December 2015 | Volume 6 | ArticleKent et al.TABLE 3 | EBC stimulus properties for research of EBC in schizophrenia.
