Little attention has been paid to neuropsychological mechanisms-of-change in counseling. A pilot study (test n=50; control n=47) tested memory priming to transform clinical mental states into real/sham antidote forms, added to psychodynamic, CBT, and humanistic counseling. Real priming significantly sped up depression reduction (SMD 1.01) and wellbeing increase relative to sham (SMD 0.95, ps<.001), showing the value of targeting core memory systems within traditional mental health counseling.
