Driving anger scale validation: Relationship of driving anger with the aberrant driving behaviour of truck drivers

Truck-related accidents in China have substantially increased. Truck driver safety issues have elicited considerable attention from transportation safety researchers. Driving anger is one of the most important factors that influence driving behaviour. However, little knowledge about the driving anger of truck drivers was available in the relevant literature. This study aimed to (1) provide empirical data about the driving anger of truck drivers, (2) examine the factor structure and psychometric properties of the driving anger scale (DAS) with a sample of truck drivers and (3) explore how the driving anger of truck drivers predicts their aberrant driving behaviour. The three-part survey data from 475 randomly selected truck drivers were collected in this study. The self-reported aberrant driving behaviour that was measured with the driving behaviour questionnaire was predicted by the drivers’ DAS ratings. One-factor structure and three-factor structure of the DAS were tested for Chinese truck drivers. Results indicated that the one-factor structure of the six-item DAS was more suitable for truck drivers than the three-factor structure. The factor structure of the DAS for Chinese truck drivers was consistent with the structure of the original version by Deffenbacher, Oetting, and Lynch (1994). The internal consistency, convergent validity and criterion-related validity of the six-item DAS were acceptable. Driving anger amongst truck drivers can be used to predict their aberrant driving behaviour. This study identified several practical implications to reduce the driving anger of truck drivers and consequently improve their driving behaviour.

Cross-cultural differences in driver aggression,aberrant, and positive driver behaviors

The present study investigated differences in driver aggression for self and others within countries and cultural differences between driver aggression, aberrant, and positive driver behaviors across five countries (Estonia, Greece, Kosovo, Russia, and Turkey). It was predicted that drivers from these five countries differ significantly in terms of driver aggression for self and others, aberrant, and positive driver behaviors. In the study, 743 participants completed the questionnaire package, including the Driver Aggression Indicators Scale (DAIS), the short version of the Driver Behavior Questionnaire (DBQ) with items from the Positive Driver Behavior Scale, and the Demographic Information Form. Paired samples T-tests were conducted to examine the differences in driving aggression between self and others in the five countries. The results indicated that, except for Russian drivers, drivers reported that other drivers had higher driver aggression than themselves. To examine the cross-cultural differences, analysis of covariance (ANCOVA) tests were conducted for the two dimensions of the DAIS (hostile aggression and revenge, and aggressive warnings) and the three dimensions of the DBQ with items from the Positive Driver Behavior Scale (errors, violations, and positive driver behaviors). Cross-country item-based comparisons were then made for the DAIS and the DBQ. The ANCOVA results showed significant differences in both item-based and subscale comparisons. Russian drivers were significantly different from other drivers in terms of hostile aggression and the revenge subscales of the DAIS and positive driver behaviors. Turkish drivers were significantly different from other drivers in several items of the DBQ, including errors and violations. The findings suggest that culture-specific strategies might be conducted for traffic-related anger management. Furthermore, differences in errors and violations among the five countries may be due to cultural differences. Positive driver behaviors might be better promoted in countries by drawing on their distinct cultural road safety strategies.     

The Effect of Reminders of Death on Reckless Driving: A TerrorManagement Perspective

Why do young people, especially young men, engage in reckless driving despite the fact that this behavior contradicts the basic biological imperative of self-preservation? Answering this interesting and crucial question may lead to effective interventions. A series of studies, based on terror management theory, examined the effects of reminders of death on risk taking while driving. The dependent measures were either self-reported behavioral intentions of risky driving or driving speed in a car simulator. Findings showed that mortality-salience inductions led to more risky driving than the control condition only among individuals who perceived driving as relevant to their self-esteem. The introduction of positive feedback about driving eliminated this effect. The complex role of self-esteem in the process of risk taking is discussed.     

Separating the effects of salience and disparity on the rate of observing

Pigeons producing deliveries of grain on a mixed variable-interval, extinction schedule by pecking a center key could also produce discriminative stimuli on concurrent variable-interval schedules by pecking the left or right observing key. The stimuli produced by each observing key were varied independently. In the first experiment, the negative discriminative stimulus was at the far end of the spectrum from the key illumination accompanying the mixed schedule and from the positive discriminative stimulus. When the magnitude of the difference between the latter two stimuli (salience) was varied, more pecks occurred on the observing key producing the larger of the two differences than on the key producing the smaller difference. In the second experiment, the stimulus accompanying the mixed schedule was at the far end of the spectrum, and the magnitude of the difference between the two discriminative stimuli (disparity) was varied. The proportion of pecks occurring on each observing key shifted systematically in the direction of the key producing the larger difference. The salience of the discriminative stimuli and their disparity each has an independent influence on the frequency of observing when the other is controlled, but the effect of the salience appears to be the more substantial.     

Acquisition of stimulus control while introducing new stimuli in fading.

After establishing discrimination between a red positive stimulus and a green negative stimulus, the lowest intensity colors that restricted all responding to the positive stimulus were determined. Then, two new white lines differing in terms of line orientation were each superimposed on one of the colors and were increased in intensity. Thereafter, the intensity of the colors was decreased and eventually eliminated. Probe stimuli consisting of the lines presented against dark backgrounds were presented before each change of stimulus intensity, and probe responding was used to assess the control acquired by various dimension of the new stimuli during the course of fading. The lines acquired control of responding while they were being introduced, and control was strengthened as the colors were attenuated. Such a locus of acquisition was attributed to the starting intensity of the original controlling stimuli and was explained in terms of stimulus blocking. Finally, using probes while introducing the new stimuli enhanced the acquisition of control by the new stimuli.     

Reversibility of single-incentive selective associations.

Rats were trained to press a lever in the presence of a tone-light compound stimulus and not to press in its absence. In each of two experiments, schedules were designed to make the compound a conditioned punisher for one group and a conditioned reinforcer for the other. In Experiment 1, one group's responding produced food in the presence of the compound but not in its absence. The other group's responding terminated the compound stimulus, and food was presented only in its absence. When tone and light were later presented separately, light controlled more responding than did tone in the former group, but tone gained substantial control in the latter. The same effects were also observed within subjects when the training schedules were switched over groups. In Experiment 2, two groups avoided shock in the presence of the compound stimulus. In the absence of the compound, one group was not shocked, and the other received both response-independent and response-produced shock. When tone and light were presented separately, the former group's responding was mainly controlled by tone, but the latter group's responding was almost exclusively controlled by light. These effects were also observed within subjects when the training schedules were switched over groups. Thus, these single-incentive selective association effects (appetitive in Experiment 1 and aversive in Experiment 2) were completely reversible. The schedules in which the compound should have been a conditioned reinforcer consistently produced visual control, and auditory control increased when the compound should have become a conditioned punisher. Currently accepted accounts of selective associations based on affinities between shock and auditory stimuli and between food and visual stimuli (i.e., stimulus-reinforcer interactions) do not adequately address these results. The contingencies of reinforcement most recently associated with the compound and with its absence, rather than the nature of the reinforcer, determined whether auditory or visual stimulus control developed.     

死亡凸显对消费者体验性消费选择偏好的影响及其作用机制

消费者的决策心理与购买行为会受到周边环境暴露的死亡信息的影响发生变化。本文从意义维持模型出发,通过4个实验探讨了死亡凸显对消费者体验性消费选择偏好的影响及其作用机制。结果发现,死亡凸显情境下消费者更倾向选择体验性消费。进一步分析发现,死亡凸显通过降低消费者的生命意义感提高了其对体验性消费的选择偏好。同时,社会支持对此间接效应起到了缓冲作用。研究结果初步揭示,补偿生命意义感的缺失是死亡凸显增加体验性消费选择的潜在机制,这也为新冠疫情背景下的消费者决策行为干预提供了一定参考。
