It is noteworthy that constructs examined during functional neuroimaging may differ when examined outside of the scanner (Gur, Erwin, & Gur, 1992). For example, Pinkham et al (2012) found that performance on a trustworthiness task changed when evaluated during fMRI compared to a psychological laboratory setting. Likewise, the Social Cognition and Functioning (SCAF) study indicated that the psychometric properties of measures in neuroscience may differ when used in behavioral paradigms (Green & Penn, 2013; Kern et al. 2013). It is also important to note that emotion identification may not be one construct, but multiple ones, especially when one compares identification of positive to negative emotions.
