James-Lange Theory

Vote 0 Votes

I was initially intrigued by the theory because my roommate brought it up and we had a small argument about the accuracy of it. I believe the theory is incorrect and it doesn't reflect how emotions and actions are actually formed. My roommate agrees more with the theory.
When I first think about the James-Lange Theory it seems wrong that emotions are consciously thought about after a physiological response to a stimuli. Emotions seem to be more instantaneous and produced because of stimuli without thought. I don't agree with the process that the theory explains and wanted to prove my roommate wrong.

As I looked at research and articles there were a few things that seemed to refute the theory. I didn't look for evidence to prove my theory correct, but wanted to see holes in the James-Lange Theory. There has been a lot of experiments with rats and disconnecting their viscera (internal structures) from their CNS, and emotions were still produced. This helps support that emotions are not caused from conscious thoughts after an action has taken place. Other support from research showed that similar visceral changes occurred with different emotions. One piece of evidence I like is that visceral changes seemed slower than emotional responses. All of this along with other research shows the inconsistency of the theory and helps my point.

I still believe more in the Cannon-Bard Theory or Two Factor Theory of emotion. I think there is a combination of multiple theories, but more research needs to be gathered to show this.

Can you beat a lie detector test?

There are plenty of people, websites, and shows that "prove" it's possible to lie to the lie detector without getting caught. However, how professional are these polygraphs that they're using? Here's a video taking a look at this,

Here the test accurately and easily told when he was lying even with a simple test. If this guy can't even lie about a simple number he wrote down it is going to be pretty tough to lie when there is more at stake in a police case. It also mentions in our textbook about the Pinocchio response and it seemed to come into play in this video. The guy here paused and looked a little stressed when it was time to lie, this can also be seen in other videos. Not only here, but also in everyday life there are cues that help any normal person decide when someone is lying.

So, with all of this it leads me to wonder how can the test really be beaten? How can elevated heart rates, blood pressure, respiration and other natural brain and bodily responses be controlled when your under pressure and your body knows the truth?

The textbook also mentions that the polygraphs turn up a lot of false positives. I think this is the reason people think that the test is inaccurate and beatable. However, if someone is lying I think there is a very, very high chance of it detecting it and it's difficult to beat it. Until I actually see someone beat an official polygraph and the test administrator i won't believe it. It is hard to control emotions and sensations that occur because of body reactions and the polygraphs are good enough at picking that up.
