Assessment of death attitudes: an empirical approach

The Threat Index and the Death Anxiety Scale were administered to 228 subjects. Based on the high/low criterion scores, 105 subjects were assigned to the following four groups: (a) high death threat/high death anxiety, (b) high death threat/low death anxiety, (c) low death threat/high death anxiety, and (d) low death threat/low death anxiety. During the experimental phase of the study, subjects viewed a filmstrip on death rituals in various cultures. A recall test was then administered. Results indicated no significant group differences on recall performance. Initial no-show rates for the second part of the experiment were observed in the four groups reflecting a significant negative relationship between death anxiety and initial no-show rates. The possibility of defensive responding on the Death Anxiety Scale was suggested.     

Community responses following suicide, homicide, and other deaths: the perspective of potential comforters

To determine whether actual responses of potential comforters in the community differ according to cause of death, 83 college students participated in a structured, individual interview. They were asked demographic questions about themselves, the bereaved, and the deceased, and then about various aspects of how they, and others in the community, responded to the death. Students were grouped by their reports of the cause of death (suicide, homicide, accident, natural anticipated death, or natural unanticipated death). When the death was by suicide or homicide, others were perceived as relatively less supportive of the bereaved person. When the death was by suicide, respondents themselves tended more to blame the bereaved person. When the death was by homicide, the bereaved person was perceived as reacting relatively worse. Potential comforters were relatively more shocked when the death was by homicide or accident.     

Testing the dimensionality of the self-consciousness scales

The self-consciousness scale of Fenigstein, Scheier, and Buss (1975) was subjected to internal and external consistency tests based on the classical test theory model. The scale was found to have five underlying dimensions: two for private self-consciousness (viz., self-reflectiveness and internal state awareness), two for public self-consciousness, and one for social anxiety. The confirmatory factor analysis procedures employed by Burnkrant and Page (1984) are shown to be fallible as indicators of unidimensionality. Theoretical implications of newly identified dimensions in the public self-consciousness subscale are discussed.     

Superstitious behavior in humans

Twenty undergraduate students were exposed to single response-independent schedules of reinforcer presentation, fixed-time or variable-time, each with values of 30 and 60 s. The reinforcer was a point on a counter accompanied by a red lamp and a brief buzzer. Three color signals were presented, without consistent relation to reinforcer or to the subjects' behavior. Three large levers were available, but the subjects were not asked to perform any particular behavior. Three of the 20 subjects developed persistent superstitious behavior. One engaged in a pattern of lever-pulling responses that consisted of long pulls after a few short pulls; the second touched many things in the experimental booth; the third showed biased responding called sensory superstition. However, most subjects did not show consistent superstitious behavior. Reinforcers can operate effectively on human behavior even in the absence of a response-reinforcer contingency and can, in some cases, shape stable superstitious patterns. However, superstitious behavior is not a consistent outcome of exposure of human subjects to response-independent reinforcer deliveries.     

Conditional relations by monkeys: Reflexivity, symmetry, and transitivity

Two cynomolgous macaques categorized six colors into two groups of three after conditional discrimination training (zero-delay symbolic match-to-sample). The procedures resulted in the establishment of relations among the elements of each set-relations that were not specifically trained and that can be characterized by the properties of reflexivity, symmetry, and transitivity. Each set of colors was related to a characteristic pattern of responding: One response pattern involved temporal duration (press and hold the response keys); the second response pattern entailed repeated pressing and releasing of the response keys (fixed ratio 8). Six combinations of two colors were trained, three combinations from each set. After discriminative performance stabilized for each monkey, they were tested with 10 additional color combinations, all of which differed from the training combinations. The conditional relations established between test combinations can be characterized as stimulus equivalence. The training procedures were analogous to the procedure of using category names, and have implications for understanding the function of language in the formation of equivalence classes.
