“…Adult participants are able to focus on standardized paper or computer tasks, introspect on current or past emotional and social experiences, maintain attention on repeated trials, and tolerate being stationary in a scanner. As such, researchers of social appraisal often utilize measures of self-report (e.g., Jakobs et al, 1999), as well as implicit cognition (e.g., Mumenthaler & Sander, 2012) and neural activation (e.g., Vrtička, Andersson, Grandjean, Sander, & Vuilleumier, 2008).
