The relationship between emotional arousal and long-term memory is addressed in two experiments in which subjects viewed either a relatively emotionally neutral short story or a closely matched but more emotionally arousing story and were tested for retention of the story 2 weeks later. Experiment 1 provides essential replication of the results of Heuer and Reisberg and illustrates the common interpretive problem posed by the use of different stimuli in the neutral versus emotional stories. In Experiment 2, identical slides were (...) used in both the neutral and arousal stores. Two different stories were created by varying the narration that accompanied each slide. In both experiments, subjects who viewed the arousal story both experienced a greater emotional reaction to the story than did the subjects who viewed the neutral story, and subsequently exhibited enhanced memory for the story. Subjects in Experiment 2 who viewed the arousal story also recalled more slides than did the subjects who viewed the neutral story. This effect was greatest for story phase 2, the phase in which the emotional slide narration occurred. Because this enhanced retention of the story slides cannot be explained by any differences in the slides themselves, the results provide new evidence to support the contention that emotional arousal influences long-term memory in normal human subjects.

Ritualized behavior, intuitively recognizable by its stereotypy, rigidity, repetition, and apparent lack of rational motivation, is found in a variety of life conditions, customs, and everyday practices: in cultural rituals, whether religious or non-religious; in many children's complicated routines; in the pathology of obsessive-compulsive disorders (OCD); in normal adults around certain stages of the life-cycle, birthing in particular. Combining evidence from evolutionary anthropology, neuropsychology and neuroimaging, we propose an explanation of ritualized behavior in terms of an evolved Precaution System geared (...) to the detection of and reaction to inferred threats to fitness. This system, distinct from fear-systems geared to respond to manifest danger, includes a repertoire of clues for potential danger as well as a repertoire of species-typical precautions. In OCD pathology, this system does not supply a negative feedback to the appraisal of potential threats, resulting in doubts about the proper performance of precautions, and repetition of action. Also, anxiety levels focus the attention on low-level gestural units of behavior rather than on the goal-related higher-level units normally used in parsing the action-flow. Normally automatized actions are submitted to cognitive control. This “swamps” working memory, an effect of which is a temporary relief from intrusions but also their long-term strengthening. Normal activation of this Precaution System explains intrusions and ritual behaviors in normal adults. Gradual calibration of the system occurs through childhood rituals. Cultural mimicry of this system's normal input makes cultural rituals attention-grabbing and compelling. A number of empirical predictions follow from this synthetic model.

Previous research has demonstrated that self-involvement enhances the memorability of information encountered in the past. The emergence of this effect, however, is dependent on guided evaluative processing and the explicit association of items with self. It remains to be seen, therefore, whether self-memory effects would emerge in task contexts characterized by incidental-encoding and minimal self-involvement. Integrating insights from work on source monitoring and action recognition, we hypothesized that the effects of self-involvement on memory function may be moderated by the extent (...) to which encoding experiences entail volitional processing. The results of three experiments supported this prediction. Despite the adoption of an incidental task context and stimulus materials that were inconsequential to participants, the act of selection enhanced the memorability and accessibility of information. The implications of these findings for contemporary treatments of self are considered. (shrink)

Bringing Ritual to Mind explores the cognitive and psychological foundations of religious ritual systems. Participants must recall their rituals well enough to ensure a sense of continuity across performances, and those rituals must motivate them to transmit and re-perform them. Most religious rituals the world over exploit either high performance frequency or extraordinary emotional stimulation to enhance their recollection. But why do some rituals exploit the first of these variables while others exploit the second? McCauley and Lawson advance the ritual (...) form hypothesis, arguing that participants' cognitive representations of ritual form explain why. Reviewing evidence from cognitive, developmental and social psychology and from cultural anthropology and the history of religions, they utilize dynamical systems tools to explain the recurrent evolutionary trajectories religions exhibit.
