PSYC 155 Lecture Notes - Lecture 17: Genetic Marker, Threshold Of Pain, Biofeedback
Document Summary
Cycle of pain-offset relief: can work the other way around too. Dampening of own pain when watching spouse in pain: the more empathetic the women were, the better was their descending pain inhibition when they observed their spouse in pain. In dorsal anterior cingulate cortex (dacc: naomi eisenberger et al. , 2006, pain threshold goes down when you"re in an emotionally upset state, tolerates more pain when not upset. Tolerates less pain when upset: new plasticity gene, u-opioid receptor gene (oprm1, mu-opioid re(cid:272)eptor ge(cid:374)e is a ge(cid:374)eti(cid:272) (cid:373)arker that"s (cid:271)ee(cid:374) li(cid:374)ked to physi(cid:272)al pain sensitivity. Individuals with g-allele tend to be more pain sensitive: 2 copies of gene a-allele and g-allele, g/g most pain sensitive. A/a least pain sensitive: g-allele individuals also have more trait sensitivity to emotional pain, casey, 2000. Females have a lower pain perception for pain threshold: women tend to have a lower threshold for feeling pain, but have a higher tolerance for pain, biofeedback:
