Autonomic Differences in Facial Expressions
Our biology is organized by these emotions. You’re feeling really happy, what’s your heart rate, stress level? What
about being angry? This must mean that biology is organized. They have just established this facial way of defining
emotions. Heart rate as indicators; have people relive emotions (i.e. think of a time when you experienced anger).
Once your face is showing a specific expression, then you show the same physiological patterns like having
elevated heart rate in the case of anger and fear. Interestingly for anger you have higher peripheral temperature in
your fingers. You’re reliving these emotional events in your life you’re able to distinguish fear and anger by the
temperature in your fingers. The major message here is that it’s possible to distinguish emotions by the different
physiological indicators. Anger and fear look pretty similar, hard to tell apart, there’s no difference in heart rate,
but there is a difference in temperature.
Emotion effects on Emotion Recognition
How does emotion affect your cognition, judgments? That’s a big topic. Our emotions change all the time, from
moment to moment, second to second. How we take in information hasn’t really been looked at when this
emotion field started. Just like biology can differentiate the emotion, how about cognition?
Does Emotion influence our cognitive and perceptual biases?
Whether the emotion of what you’re feeling will affect some emotional cognitive biases and perception of
someone else. Mood congruency effect; in this particular case we want to induce disgust and flash those spatial
expressions on the screen and measure what their bias was. Did they see more disgust?
What is his cognitive processing style?
Flash the faces rapidly after showing happy or disgust situations. If you’re in the happy condition, if you saw a
happy face you would also see little bits of other things. You were seeing multiple possibilities. You might see
anger when you’re sad. Exploration are dependent on possibilities of whether you’re happy or sad.
How accurate is his judgment?
If you were frightened then you will project fear in other people. So if we’re talking about a disposition rather than
an induced emotion we could fine different cognitive biases. In the first example of disgust vs. happy,
Intergenerational transmission of anxiety emotional and cognitive biases
Do parents bias this? We already know that these mothers that are overprotective will have children to score
higher anxiety as well. So one possibility that's been explored is that of you are more anxious its more likely to
have negative biases. You will always focus on the negative interpretations of situations.
Anxiety produces a higher tendency to perceive stress.
Hane et. al 2011
I will read you situations such as a group of students who laugh when you walk by. What do you think is going on?
What are you going to do about it? They put themselves in that person shoes. Do they interpret that situation as a
threat to themselves? It can be a perception of laughing at your shoes. In this particular case you get the parent
