Source Analysis

I decided to look at the sources that Barbara Fredrickson used in her ""Love 2.0: How Our Supreme Emotion Affects Everything We Feel, Think, Do, and Become", and one source that really interested me was "Oxytocin increases gaze to the eye region of human faces" by Adam J. Guastella, Mitchell, and Dadds (2008). This, I believe, is a report that was published in a journal called "Biological Psychiatry". This study was done as a double blind (meaning both the experimenter and the participants did not know whether or not the participants were in the control group or experimental group), randomized design. The study was to track the eye movements of 52 healthy male volunteers who were presented with 24 neutral faces after intranasal administration or a placebo. What they found was that the participants that were given the oxytocin showed a significant increased time of looking at the eye region of the neutral faces compared to their control group counterparts. They concluded the experiment with hypothesizing that this is perhaps one way that oxytocin enhances emotion recognition (social cues) and interpersonal communication. As it was stated in the "Love 2.0: How Our Supreme Emotion Affects Everything We Feel, Think, Do, and Become", positivity resonance makes us more open and more trusting, which is what oxytocin does. Basically the more you interact with people, the more oxytocin in your brain. I thought it was interesting that the function of oxytocin can be measured like this.
