Snake fearful college students underwent Standardized Systematic Desensitization (SSD) treatment in which they received instructions designed to induce cognitions of either self- or drug-produced relaxation. Half of the subjects in each of these conditions were also given high expectancy therapy instructions and low expectancy therapy instructions respectively. All four SSD groups showed significantly greater improvement than a no-treatment control group on both the behavior avoidance test (BAT) and the self-report measure of fear. No differences between self- and drug-attributions of relaxation were found on any measure. Subjects' high expectancy ratings were significantly correlated with improvement on self-report measures but not related to BAT performance. 相似文献

The relative efficacy of the major techniques typically used in behavioral treatment programs for weight reduction was investigated using obese adult volunteers. Study 1 compared the effects of self-monitoring, self-control procedures, monetary rewards, aversive imagery and relaxation training. These procedures resulted in significantly greater weight reduction than either a no treatment group or subjects who graphed and recorded daily weight. Self-monitoring of daily caloric intake was as effective as the other methods, both singly and combined, over a 4 week treatment period. Study 2 compared the long-term effects of self-monitoring vs the full complement of behavioral techniques used in Study 1. The full behavior management program was significantly more effective, both during the treatment period and at 3 and 12 week follow-ups, although self-monitoring again produced substantial weight loss. 相似文献

Two experiments were conducted to determine the relationships between the various parameters of intermittent stimulation and the occurrence of binocular color fusion. Numerous combinations of on and off durations were presented, some synchronously and some asynchronously. Three Os were asked to report all colors experienced during the 15-sec viewing period. Experiment ] showed that fusion can be reliably obtained with on durations of less than 100 msec in combination with off durations of more than 100 msec. Experiment 2 indicated that the limit of dichoptic onset asynchrony within which color fusion reliably occurs is 25 msec. Two possible alternative hypotheses consistent with the data are discussed. 相似文献
