Han older faces (see Williams et al. Consequently,Research Aim was to examine the brainbehavior correlations in vmPFC,dmPFC,and amygdala for the facial expressions in relation to each other too as young vs. older faces in samples of young and older adults. In specific,Hypothesis a predicted a good correlation in between vmPFC activity to content relative to angry (or neutral) faces and accuracy,too as speed,of identifying happy relative to angry (or neutral) expressions in each young and older adults. A related pattern was predicted for young when compared with older faces. Moreover,comparable correlations have been expected for amygdala activity (Hypothesis b). Hypothesis c,in trans-ACPD web contrast,predicted a damaging correlation involving dmPFC activity to angry (or neutral) relative to content faces and accuracy,at the same time as speed,of identifying angry (or PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/26683129 neutral) relative to pleased expressions in both young and older participants. Once again,a comparable pattern was predicted for older when compared with young faces. The concentrate of your present paper on mPFC and amygdala as regions of interest (ROI) was motivated by evidence outlined above that these areas seem to become specifically involved in facial emotion reading in young and older adults (Keightley et al. Moreover,these regions have already been shown to become involved in thinking concerning the self in each young and older adults (Gutchess et al. Mitchell et al. Ebner et al a). That is,locations of mPFC are recruited when young (Amodio and Frith Mitchell Van Overwalle,and older (Gutchess et al. Ebner et al a) adults “mentalize” about their own or other people’s intentions,thoughts,feelings,and preferences,or empathize with them (V lm et al,that are processes that seem specifically relevant when attempting to decode other people’s feelings and feelings from facial displays as in the present study. Furthermore,these brain regions show only moderate agerelated structural modifications (Raz and Kennedy,and show largely intact functional patterns in older adults (Gutchess et al. Wright et al. Ebner et al a,in preparation),even in research that uncover general lower activity in these regions in older than young adults (Mather et al. Mitchell et al.

Investigation aim Analysis Aim : Brain activity in vmPFC,dmPFC,and amgydala through facial expression identification as a function of facial expression and age of face in young and older adults Particular study prediction Hypothesis a: Greater vmPFC activity to delighted than angry (or neutral) faces and to young than older faces across age groups Hypothesis b: Higher amygdala activity to pleased than angry (or neutral) faces and to young than older faces across age groups Hypothesis c: Higher dmPFC activity to angry (or neutral) than happy faces and to older than young faces across age groups Hypothesis d : Higher dmPFC activity to angry (or neutral) than pleased faces in older than young adults Analysis Aim : Brainbehavior correlations in vmPFC,dmPFC,and amygdala for different facial expressions and diverse age of faces in young and older adults Hypothesis a: Constructive correlations amongst vmPFC activity to happy relative to angry (or neutral) faces and capacity of identifying happy relative to angry (or neutral) faces in young and older adults; related pattern predicted for young relative to older faces Hypothesis b: Positive.
