In Professor Coane’s article, False Memory in a Short-Term Memory Task, there was a brief neuroscience reference. “Brain activity patterns associated with false memories were distinguishable from those associated with veridical memory”. I thought this was cool so I looked up some of the details. The studies she is referring to used ERPs and found lateralized brain activity only for true memories.
The idea of true vs. false memories then got me thinking about lying and whether or not those brain activity patterns are also distinguishable. If scans can pick up on false information when the person reporting doesn’t even know it’s false, it seems as though scans could pick up on false information when the person does know. I wonder if maybe ERPs could work in the criminal justice system. Could this work better than a polygraph? Maybe the brain patterns of liars aren’t distinguishable, I don’t know, I just think it’s an interesting idea that we could potentially pick out liars by looking at their brain patterns.
