Components and recognition of facial expression in the communication of emotion by actors.

This article addresses the issue of the communication of emotion by actors. In Study 1, the facial behavior of 6 actors portraying emotions as felt or unfelt were analyzed with the Facial Action Coding System. Results indicated that the portrayals of felt emotions were closer to the expression of genuine emotion than the portrayals of unfelt emotions for 3 of the 6 emotions under investigation. Study 2 examined the decoding of actors' portrayals from facial behavior. Decoders were found to be very accurate in recognizing the emotional category but not in judging the encoding condition.

The effects of formaldehyde on voluntary ethanol consumption in the laboratory rat: a comparison of two methods of determination of a single test solution.

The effect of formaldehyde on voluntary alcohol intake in rats was examined. Alcohol intake was measured using individually determined alcohol concentrations. The results did not support the tension reduction hypothesis: Stress induction did not enhance alcohol intake. It is concluded that a revision of the tension reduction hypothesis should be formulated.

Effects of unavoidable electric shocks on voluntary alcohol consumption in the rat.

The purpose of this experiment was to study the effects of electric shocks on voluntary alcohol intake in rats. Alcohol intake was measured using individually determined alcohol concentrations. Contrary to many previous studies, alcohol intake was reduced during the stressful treatment. It is concluded that accounting for individual differences in alcohol intake is important when studying the effect of stress on alcohol consumption.

Facial expressions of emotions and ethological behavioral categories.

The purpose of this study was to measure the capacity of human subjects to match facial expressions of emotions and behavioral categories that represented the motivational states they are supposed to illustrate. 100 university students were shown facial stimuli they had to classify using ethological behavioral categories. The results showed that accuracy of judgment was over-all lower than what was usually found when fundamental emotional categories were used. The data also indicated that the relation between emotional expressions and behavioral tendencies was more complex than expected.

Alcohol intake in the rat as a function of the method of selection of a single test solution.

Two methods of selection of a single test solution of alcohol were compared with 78 male Sprague-Dawley rats evenly divided into two groups that differed according to the method used. It was found that the method of selection affected many parameters of alcohol consumption, including its stability. It was concluded that the difference in the effects of the two methods was related to the fact that one method permits a higher degree of individuality for the establishment of a single test solution.

Judgment of facial expressions of emotion as a function of exposure time.

The purpose of this experiment was to study the accuracy of judgment of facial expressions of emotions that were displayed for very brief exposure times. Twenty university students were shown facial stimuli that were presented for durations ranging from 10 to 50 msec. The data showed that accuracy of judgment reached a fairly high level even at very brief exposure times and that human observers are especially competent to process very rapid changes in facial appearance.

Accuracy and latency of judgment of facial expressions of emotions.

The aim of the experiment was to study the relation between accuracy of judgment of facial expressions of emotions and time for judgment. The results for 34 college students confirmed previous data showing high performance in identification of all emotions, although there were some important differences between emotions. Also, times for judgment were longer for the emotions which were more difficult to identify.

Patient identification for computer data linkage.

To permit linkage of computerized patient data obtained from different sources, a universal and efficient method of patient identification is necessary. A coding system of 16 characters with a high degree of discrimination is proposed. The first five characters code the individual's family name, the next four his given name; the next six digits are his date of birth expressed in day, month and year; and the last character codes his sex. This system, using readily available patient information, is simple to manipulate and generates codes that are also medically informative. When this method of identification was tested on a list of 18,000 persons, no identical codes were found.
