Decreased Reception of Nonverbal Cues in Heroin Addicts

The ability to interpret nonverbal cues was tested in 15 young, white American male heroin addicts who were not intoxicated. When their responses were compared with those of age-matched controls, addicts were found to be significantly less accurate in reading nonverbal communications.     

Hope as Grounds for Forgiveness

It is widely assumed that Christianity enjoins its followers to practice universal, unconditional forgiveness. But universal, unconditional forgiveness is regarded by many as morally problematic. Some Christian scholars have denied that Christianity in fact requires universal, unconditional forgiveness, but I believe they are mistaken. In this essay, I show two things: (1) that Christianity does enjoin universal, unconditional forgiveness of a certain sort, and (2) that Christians, and perhaps other theists, are always justified in exercising unconditional forgiveness. Though most philosophers treat forgiveness as grounded in our beliefs about the offender's current state, I argue that we might more fruitfully ground forgiveness in hope for the wrongdoer. Christianity's commitment to the existence of an omnipotent God who is concerned about the moral status of His creatures always justifies such hope and thus always justifies forgiveness.     

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.     

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.
