ABSTRACT

Klara […] was working on the medium difficulty problem. In the first few minutes, she experienced anxiety, which was discernible from her nonverbal expression.… She confirmed that she indeed was anxious.… The heart rate at about this time accelerated significantly.… Similarly, as Klara continued working on the problem she experienced anger. This was evident in her face too.… The heart rate measure also revealed a significantly increased heart rate.… As Klara completed about 75% of the task, enjoyment surfaced. Corresponding [heart rate changes] were not significant […], but the clear drop from those of anger and anxiety suggests that the associated decrease was consequential.… Toward the end of the task, Klara reported being anxious.… In spite of Klara’s subjective experience of anxiety, neither her non-verbal expression nor her heart rate signaled the emotion.
