A molecular analysis based on the termination of stimuli that are positively correlated with shock and the production of stimuli that are negatively correlated with shock provides a parsimonious count for both traditional discrete-trial avoidance behavior and the data derived from more recent free-operant procedures. The necessary stimuli are provided by the intrinsic feedback generated by the subject's behavior, in addition to those presented by the experimenter. Moreover, all data compatible with the molar principle of shock-frequency reduction as reinforcement are also compatible with a delay-of-shock gradient, but some data compatible with the delay gradient are not compatible with frequency reduction. The delay gradient corresponds to functions relating magnitude of behavioral effect to the time between conditional and unconditional stimuli, the time between conditioned and primary reinforcers, and the time between responses and positive reinforcers. 相似文献

The aim of the present study was to investigate the relationship between extraversion, neuroticism and psychoticism, and road traffic fatalities in a data set of 34 nations. In addition to traffic fatalities per 100,000 vehicles, work-related fatalities were included in the study. Results showed that extraversion had a positive relation to the number of traffic fatalities whereas neuroticism correlated negatively with road fatalities. Occupational fatalities were strongly related to deaths on the roads but not to personality dimensions. Countries with high extraversion scores had more traffic fatalities than countries with moderate or low extraversion scores. The need for well-designed studies investigating the link between personality factors and traffic accident liability via driver behaviour was expressed. 相似文献

The present study examined the impact of Primacy/Recency Effects and Hazard Monitoring on driver attributions. Participants viewed a simulated near collision from the perspective of a trailing motorist. The amount of error free driving prior to the near collision varied between two groups, where the near incident occurred either early or later in their viewing experience. They were then given the opportunity to provide judgments of the offending driver based on how safe, dangerous, risky, and skilled the driver was in general, and to evaluate their overall performance. Results showed a Primacy Effect dominance in that judgments of the driver were most negative in the early group, but this was moderated by high Hazard Monitoring for ratings of “dangerous” and “safe”. This suggests that judgments of other drivers are likely to be quick and based on early information, but are impacted by personal factors such as a tendency to monitor for hazards. 相似文献

The relation between heart-rate deceleration and the expression of positive affect in infancy is examined by testing the hypothesis that intensity of orienting (as indexed by heart-rate deceleration) is predictive of intensity of positive affect (smile size and duration). A social-stimulation procedure was utilized to elicit smiles in 41 3-month-old infants. The first smile elicited was coded for smile size and duration, and the preceding heart-rate deceleration was coded for magnitude, duration, and slope of deceleration. Slope and duration of heart-rate deceleration proved to be reliable predictors of smile size, but none of the heart-rate measures correlated with smile duration. Results suggest that the steeper and more rapid the deceleration, the larger the ensuing smile. Possible mechanisms for this finding are discussed. 相似文献

Many deaths from cardiopulmonary arrest can be prevented by the prompt and effective administration of cardiopulmonary resuscitation (CPR). In this study, we examined the standard training program for teaching CPR to emergency medical technicians (EMTs). We developed an alternative experimental program whereby the behaviors involved in CPR were assessed easily and in greater detail. This assessment provided the basis for a system in which effective CPR skills were reinforced and problems were corrected. Subjects who were trained in CPR according to this experimental program performed more effectively than subjects in the standard program. In addition, retention (maintenance) measures indicated that experimental subjects continued to perform well, often more effectively than professionally employed EMTs. 相似文献

Behavioral determinants of mothers' safety measures to prevent injuries of pre-school children 总被引:4,自引:0,他引:4
Home-related injuries are a major threat to pre-school children in the western world. In this study the behavioral determinants of 18 parental safety measures were assessed. To select behavioral determinants, the Attitude-Social influence-Self-efficacy/barriers model was used with the inclusion of variables from the Health Belief Model and the Protection Motivation Theory. A written questionnaire was completed by 1129 Dutch mothers of pre-school children. Most safety measures were explained (rather) well by the same set of determinants. Main determinants for adopting or not adopting a safety measure were the mother's belief in the necessity of the safety measure according to the child's age, her belief about her partner's opinion on the necessity and her belief about the success of taking the measure. Subsequent important determinants were the mother's belief about the inconvenience and instrumentality of the safety measure; the perceived susceptibility had a minor or moderate influence on most measures. This study did not indicate that more highly educated mothers were more knowledgeable about safety-related subjects. The theoretical implications of this study are discussed. 相似文献

An incentive program to motivate seat belt use was implemented at a large munitions plant. Seat belt usage was assessed daily at an entrance/exit gate of the industrial complex when employees arrived for work in the morning and departed in the afternoon. During treatment incentive fliers, which prompted seat belt usage and gave belt wearers opportunities to win prizes, were distributed only in the afternoon. Seat belt wearing increased from baseline means of 20.4% and 17.3% during the morning and afternoon, respectively, to averages of 55.5% during afternoon departures and 31.1% during morning arrivals. During follow-up, mean belt use dropped almost to baseline levels. Categorizing vehicles according to driver sex and license plate number enabled a study of belt wearing practices of individuals, and revealed that the incentive program influenced some drivers to wear their seat belts during morning arrival when incentives were not distributed (i.e., treatment generalization) and during a follow-up period after the incentives were withdrawn (i.e., response maintenance). 相似文献

We evaluated the efficacy of a commercially available program, the Red Flag, Green Flag Prevention Book, used by parents to teach their children personal safety skills. Children's knowledge and skills regarding the prevention of sexual abuse and abduction were assessed prior to, during, and after training. In one group, training consisted of parents using the prevention book to train their children. Parents of children in the second group used the prevention book with added instructions. Children who did not achieve criterion performance after training with the prevention book received behavioral skills training provided by the experimenter. All children acquired safety skills following behavioral skills training. Follow-up probes 2 months later showed skill maintenance among the older children. Parents reported satisfaction with the procedures and no signs of behavioral or emotional problems following the follow-up probe. 相似文献

The seat belt usage of drivers was observed at the entrance to two campus parking lots during morning arrival times. After 11 days of baseline, fliers which prompted seat belt wearing were handed to drivers of incoming vehicles. At one parking lot all fliers offered a chance to win a prize (noncontingent rewards); while at the second lot only those fliers given to seat belt wearers included a chance to win a prize (contingent rewards). After 24 consecutive observation days, these interventions were removed for 14 days of withdrawal. The recording of vehicle license plates enabled an analysis of belt usage per individual over repeated exposures to the experimental conditions. At the lot with the contingent reward intervention, mean belt usage was 26.3% during baseline, 45.7% during treatment, and 37.9% during withdrawal. At the noncontingent reward lot, the mean percentage of belt wearing was 22.2% during baseline, 24.1% during treatment, and 21.8% during withdrawal. The analysis of repeated exposures per individual verified that only contingent rewards influenced substantial increases in belt wearing, and showed that most of the influence occurred after the initial incentive prompt. 相似文献
