1. Heat production and heart rate of seven steers were measured simultaneously using either a calori- metric chamber or head-cage.2. The relationship between heat production and heart rate for each animal was best described by linear regression.3. Differences between individual animals made separate ‘calibration equations’ necessary for each animal.4. Accuracy of prediction of heat production from heart rate was better than ±10% in all instances.5. It is concluded that frequent measurement of heart rate appears to offer a practical method for esti- mation of heat production of free-range animals.

The Relationship

In this article, we report on a multimethod qualitative study designed to explore the emotional experiences of students in the classroom setting. The purpose of the study was threefold: (1) to explore the correspondence among nonverbal expressions, subjective feelings, and physiological reactivity (heart rate changes) of students’ emotions in the classroom; (2) to examine the relationship between students’ emotions and their competence and value appraisals; and (3) to determine whether task difficulty matters in emotional experiences. We used multiple methods (nonverbal coding scheme, video stimulated recall interview, and heart rate monitoring) to acquire data on emotional experiences of six grade 7 students. Concurrent correspondence analyses of the emotional indices revealed that coherence between emotional response systems, although apparent, is not conclusive. The relationship between appraisals and emotions was evident, but the effect of task difficulty appears to be minimal.
