Teaching with symbols tangentially related to topic: using a linked multimedia approach to enhance learning.

40 undergraduate students, none of whom were history or literature majors, attended a lecture on Medieval literature. For half the students the lecture was supplemented by two sets of slides. One set summarized course content while the second set contained slides of paintings or other forms of visual art which were only tangentially related to the topic. For the other half of the student-group, the lecture was supplemented by course content slides only. Students viewing symbolic slides had significantly higher test scores on a written 20-question multiple-choice test given immediately after the lecture.

Measurement of nonverbal receptive abilities in medical students.

Physicians have been reported to have difficulty in communicating with their patients. An element of this communication gap is proposed be related to the educational curriculum and the selection process of medical schools, in particular, with the emphasis on scientific methodology reducing exposure to humanistic values. This hypothesis was tested by measuring nonverbal receptive abilities in two groups. 30 medical students were compared with 30 college students who were not science majors but were age-, sex- and race-matched. The nonscience majors were better at perceiving nonverbal cues than medical students. Male nonscience majors had higher scores than male medical students while similar results were seen when female nonscience majors were compared with female medical students. Finally, medical students planning to practice as primary care specialists had higher scores than those interested in specialties which do not involve direct or prolonged patient care.

Perception of nonverbal facial cues in chronic phencyclidine abusers.

The ability to interpret nonverbal facial cues was tested in 10 young white male chronic phencyclidine (PCP) abusers. When their responses were compared with those of age-matched controls, abusers were significantly more accurate in interpreting the facial cues of videotaped medical interns. Phencyclidine abusers tend to form a socially maladroit and downwardly mobile group. However, previous studies of similar maladroit populations such as heroin addicts have indicated that they are less accurate in interpretation of nonverbal facial cues. The complex action of multiple affected neurotransmitters in PCP abusers was examined. Dopamine and serotonin were thought to be the relevant transmitters.

Sexualization of the female foot as a response to sexually transmitted epidemics: a preliminary study.

The authors reviewed historical literature and hypothesized a relationship between epidemics of sexually transmitted diseases and foot fetishism. They tested this hypothesis by quantifying foot-fetish depictions in the mass-circulation pornographic literature during a 30-yr. interval. An exponential increase was noted during the period of the current AIDS epidemic. The authors offer reasons for this possible relationship.

Cholera and nightsoil infection in Hong Kong, 1966.

In 1966 there occurred in Hong Kong the rare combination of, in one area, a non-imported case of cholera with no nightsoil infection and, in another area, heavy infection of the nightsoil with no cholera cases. Investigation revealed that there was no connexion between the case (in Kowloon) and the short-lived nightsoil infection (on Hong Kong Island). The hypothesis is advanced that the infection of 5 premises was due to their being visited by a ship's crew, who later left Hong Kong, without the infection spreading to the permanent residents. The authors stress that, in slightly different circumstances and without the existing system of nightsoil monitoring, this infection would not have been detected and cases of cholera might have occurred with no forewarning.
