I found this to be a rather interesting article. I think it directly relates to the material we studied in Chapter 3 (dealing with the emotional brain). One of the main reasons I found it interesting is because it seems to go against common sense, or at least against conventional wisdom. Many of us have undoubtedly heard others tell us not to go to bed angry, but this study suggests that "brain activity (specifically in the lateral prefrontal cortex) is a far better indicator of how someone will feel in the days following a fight with his or her partner." Generally those who had high activity in this area had a better mood than those who had low activity in this area. I believe what helps set this recent study apart is that it did not take place entirely in a laboratory, but also involved real situations/relationships. In other words, one can probably be more confident of its external validity.
In our textbook (starting on p. 61 in Chapter 3), Reeve writes about the relationship between the prefrontal cortex and affect. Here it mentions that, "the limbic system receives incoming sensory stimulation (that) activate rather automatic emotional reactions... stimulation of the cortex can generate emotional states." Reeve also makes the point that one must make a distinction between the left and right side of the prefrontal cortex because each is qualitatively different from the other. Reeve also makes reference to the Behavioral Inhibition System, which includes the two dimensions of personality, one of which is "how sensitive versus stable a person is to threats, punishments, and the experience of negative emotion (Reeve 2009, p.61)."
I was actually rather impressed with the physiological measures used - researchers used an fMRI, recorded facial expressions, and tested cognitive skills. As I mentioned before, the researcher (Hooker) found that the level of activity in their lateral prefrontal cortex may be a significant factor in predicting a person's experiences, ability to bounce back, etc.
The main reason why I chose this article and wanted to share it with others is because I am rather fascinated by the unconscious activity that takes place in the brain. As others probably have heard, there have been studies that suggest people actually have a tendency to make better decisions having slept on it - I think I heard about this in Social Psychology. I believe I also heard data that supports this in my BioPsychology course. While sleeping, our brain continues to process information. It's very interesting to think of the possibility that being angry while we go to sleep may actually help us better deal with our problems, confront them face on with our subconscious attention. This may be drifting a little bit from Motivation and Emotion, but I find it very interesting how I have often woken up with solutions to some of my problems that I had never thought of before - I believe my mental activity throughout the night has sometimes helped me come up with effective solutions.
In any case, this study does provide insight and understanding into physiological activities, such as the activation of certain brain structures and subsequent impact on emotional states. For the reasons I have mentioned, I actually believe this type of research is very important and may lead to more effective interventions for people facing certain problems, such as depression.
The article ends with the following...
While Hooker acknowledges that more work must be done to develop clinical applications for the research, it may be that lateral prefrontal cortex function provides information about a person's vulnerability to develop mood problems after a stressful event. This raises the question as to whether increasing lateral prefrontal cortex function will improve emotion regulation capacity.
