The effects of police surveillance and law enforcement on driver behaviour

Police surveillance and enforcement activities can have a significant effect on the compliance of traffic rules and regulations. The extent to which road users are influenced by traffic law enforcement depends on the strategies used in police surveillance and on the efficiency of the punitive system. Although police surveillance can have limited and transient effects, the punitive system does not seem able to cope with the demands of the traffic system. Alternative approaches to traffic behaviour control are suggested that could have far greater impact on the behaviour of road users.     

Effects of driver cell-phone use on driver aggression

Using 2 field procedures, the authors assessed impacts of cell-phone use on mild forms of driver aggression. Participants were 135 drivers traveling within a city of approximately 17,000 people in an otherwise little-populated region of western North Dakota. The authors videotaped the participants while a confederate driver in a low-status vehicle frustrated them. In Experiment 1, the confederate was traveling well under the posted speed limit. In Experiment 2, the confederate remained motionless at a stoplight that had turned green. When the confederate visibly talked on a hand-held cell phone (n = 67), male drivers exhibited their frustration by honking their horn more quickly and frequently than did drivers in no-cell-phone trials, and female drivers were more angry according to blind judgments of videotaped facial expressions that were compared with those of drivers in no-cell-phone trials (n = 68). The present results suggested that driver cell-phone use contributes to the growing crisis of roadway aggression.     

Field operational test of a seatbelt reminder system: Effects on driver behaviour and acceptance

The long-term effects on driver behaviour and acceptance of a seatbelt reminder system were examined in an on-road study. The system was capable of detecting seatbelt use in all seating positions and produced a two-stage visual and auditory warning if occupants were unrestrained. The effects of this system were evaluated alone and in combination with two other intelligent transport systems: intelligent speed adaptation and a following distance warning system. Twenty-three fleet car drivers drove an instrumented vehicle (SafeCar) for at least 16,500 km as part of their everyday driving. The results revealed that driver and passenger interaction with the seatbelt reminder system led to large and significant decreases in the percentage of trips where occupants were unbelted, in the percentage of total driving time spent unbelted, and in the time taken to fasten a seatbelt in response to system warnings. The seatbelt reminder system was rated by drivers as being useful, effective and socially acceptable, and led to a decrease in drivers’ subjective workload. These results were found even though the baseline pre-exposure seatbelt wearing compliance rates among participants were high.     

A constraint on comparisons: Equally detailed alternatives

Children's errors in collective comparison tasks are atributed to the comparison of the wrong classes. It is specifically hypothesized that alternative classes are erroneously formed subject to the constrain that the same kinds of properties are criterial for each alternative. This hypothesis, called the equally detailed alternatives hypothesis, is tested in three experiments with hierarchically organized stimuli and requests to compare a superordinate class and a nonincluded subclass, for example, dogs and yellow cats. In all three experiments 4-year-old children's comparisons were found to be in accord with the hypothesis. In the first experiment both perceptual and linguistic factors determine which classes are compared. In the second experiment, as predicted, erroneous subclass comparisons were more common when all subclasses were distinguished by the same kinds of properties. In the third experiment, the children were asked to partition the stimulus objects into the classes to be compared. The vast majority of partitions were erroneous and in accord with the hypothesis. Potential benefits of the constrain are considered.     

A detailed examination of mediation in PA learning

This paper reports a single experiment in which verbal and imaginal mediators were compared in paired-associate learning. Pair concreteness and delay of recall (immediate vs 1-week delay) were also manipulated. The dependent variables included the latencies of mediator discovery and mediator production, response recall, mediator recall, and recall latency. A variety of differences between verbal and imaginal codes were found in the dependent measures. In addition, a profound effect of immediate recall on subsequent recall was discovered. The results are discussed in terms of the differences between the two modalities of memory.     

A controlled evaluation of the impact of a parent training programme on child behaviour and mothers' general well-being

This study was designed to assess the impact of a parent training programme run by the Eastern Health Board (EHB) on two factors, child behaviour and mothers' general well-being. Thirty-nine mothers (Experimental group), and forty mothers on a waiting list for the course (Control group), were assessed before the Experimental group commenced the course and again when the Experimental group had completed the course. The Experimental group was also assessed one year after completing the course. Although initially the Control group started from a slightly better position, statistically significant for one of the four measures, mothers in the Experimental group changed more during the course and rated their children as having fewer and less intense behavioural problems, and saw themselves as having fewer psychological symptoms and increased levels of self-esteem at post-course assessment. These beneficial effects were maintained at follow-up.     

A critical evaluation of some commonly-employed methods for the assessment of type a coronary-prone behaviour

Type A coronary-prone behaviour has been repeatedly associated with an increased incidence of coronary heart disease (CHD) amongst middle-aged men and women. This association appears to be independent of other standard CHD risk factors such as smoking, high blood pressure and elevated serum cholesterol levels. This paper presents normative and correlational data for a number of commonly-employed self-report measures of Type A behaviour and the structured interview. These data replicate U.S. findings that self-report measures tend to correlate only moderately with the Structured-Interview method of assessment of Type A behaviour. The implications of these data for researchers attempting to assess Type A behaviour, especially with limited resources, are discussed.     

The impacts of an air-crash on students’ transportation choice behaviour: An empirical study undertaken in Taiwan

This research’s objectives are to identify major factors influencing offshore student–commuters’ transportation mode-choice and to develop simple Logit choice models prior and post a major air disaster. The total trip time, trip cost, ease of access to a transportation mode, student–commuters’ household income, and the risk perceived by student–commuters using different transportation modes are found to have impacts on their mode-choice behaviour. Several logit model specifications were tested. The research reveals student–commuters’ transportation mode-choice behaviour significantly changed post the May 2002 Penghu air accident. Reduction in airfares (which most airlines used to promote their services after the air-crash) was less attractive to passengers than convincing them that airline services were safe. Therefore, any post-disaster airline marketing campaign aimed at student–commuters should change from reduced fare promotion to service safety promotion.     

An evaluation of the effectiveness of Diploma-level training in cognitive behaviour therapy

Background

As part of the UK government’s initiative to Increase Access to Psychological Therapies (see http://www.iapt.nhs.uk/for full details of the IAPT programme) there has been an expansion in the provision of post-graduate Diploma training in cognitive behaviour therapy (CBT). Previous evaluations of such training programmes have yielded mixed results but have been limited by small sample sizes and/or limited assessment measures.

Aims

To evaluate the impact of a long-standing Diploma in CBT training programme on a variety of measures of CBT competence.

Method

Trainees’ levels of CBT skill are compared at the beginning and end of CBT training. The effect of therapist factors such as age, professional background and gender on the development of CBT competence is also examined.

Results

Results show that trainees demonstrate higher levels of CBT skills after completing the training than they did before, with the majority achieving pre-determined criteria for competence. Trainees’ gender was not related to their performance but trainees’ age showed a negative association with CBT skill (older trainees performed worse). Trainees’ professional background also had an impact on their level of CBT competence, with trainees who were clinical psychologists demonstrating the highest levels of competence across a range of measures.

Conclusions

CBT Diploma training leads to increases in the level of trainees’ CBT competence, with the majority achieving the levels demonstrated in research trials by the end of training. Thus, this training is likely to lead to improved outcomes for patients. Further research is needed to determine the most efficient ways of enhancing CBT skills.     

A functionalist account of shame-induced behaviour

Recent research has shown that shame activates both a restore and a protect motive (De Hooge, Zeelenberg, & Breugelmans, 2010), explaining the hitherto unexpected finding that shame can lead to both approach and avoidance behaviours. In the present article we show a clear difference in priority and development of restore and protect motives over time. Our experiment reveals that shame mainly motivates approach behaviour to restore the damaged self, but that this restore motive decreases when situational factors make it too risky or difficult to restore. In contrast, the motive to protect one's damaged self from further harm is not influenced by such situational factors. As a consequence, the approach behaviour that shame activates may change over time. These findings add to our understanding of the motivational processes and behaviours following from shame.     

The growing field of nonverbal behaviour: A review of twelve books on nonverbal behaviour and nonverbal communication

This book review covers two monographs and ten edited books, mostly psychological in orientation and centered on current research questions about nonverbal behaviour or nonverbal communication. The edited books comprised 213 contributors. In each case, the reader is informed about the origin of the book, its main emphasis, the kind of topics covered, the nature of the material presented (whether theoretical discussions, reviews of research, research reports…), its general interest, and the type of readers who would mostly benefit of it. The material has been organized into five classes: Books of readings, introductory books, books on methods, specific dimensions, and specific topics.     

A detailed study of sequential saccadic eye movements for normal- and poor-reading children

This paper presents the results of an in-depth study of parameters characterizing sequenced saccadic eye movements for a group of dyslexic children and a comparative normal control group with ages in the range greater than 8.0 yr. and less than 13.0 yr. No parameters were statistically different for the two groups, which supports the findings of Brown, et al. and contradicts the findings of Pavlidis. Our results indicate that sequenced saccadic eye movements are not diagnostically useful for early detection of dyslexia.     

Assessment of sexually abused children with anatomically detailed dolls: A critical review

The use of anatomically detailed (AD) dolls is widespread, especially with young children who have been, or may have been, sexually abused. A number of empirical studies have compared the responses of sexually abused and non-abused children to AD dolls. Additional research has assessed AD doll play among non-abused children only. Methodological limitations notwithstanding, virtually all empirical data support the use of AD dolls for data gathering in cases of sexual abuse.     

Effects of a driver enforcement program on yielding to pedestrians

A driver-yielding enforcement program that included decoy pedestrians, feedback flyers, written and verbal warnings, and saturation enforcement for a 2-week period was evaluated in the city of Miami Beach using a multiple baseline design. During baseline, data were collected at crosswalks along two major corridors. Treatment was introduced first at selected crosswalks without traffic signals along one corridor. A week later, enforcement was shifted to crosswalks along the second corridor. Results indicated that the percentage of drivers yielding to pedestrians increased following the introduction of the enforcement program in each corridor and that these increases were sustained for a period of a year with minimal additional enforcement. The effects also generalized somewhat to untreated crosswalks in both corridors, as well as to crosswalks with traffic signals.     

A critical assessment of pedestrian behaviour models

This paper concerns a review and critical assessment of the existing research on pedestrian behaviour in urban areas, focusing on two separate yet complementary aspects: route choice and crossing behaviour. First, an exhaustive review of the existing route choice models for pedestrians is presented. It is shown that the existing models are mainly more stochastic and more macroscopic than required and seldom incorporate the interactions between pedestrians and traffic. Second, the existing models on pedestrians crossing behaviour are presented and assessed. It is shown that, although their approach is usually detailed, deterministic and traffic-oriented, they are mainly devoted to a local level behaviour and focus on only one type of all the potential determinants. Most importantly, these two complementary and possibly interdependent aspects of pedestrian behaviour are always examined separately. The results of this review reveal a lack of an overall and detailed consideration of pedestrian behaviour along an entire trip in urban areas. Moreover, the need for an integrated approach based on flexibility, disaggregation and more determinism is identified. Accordingly, a set of modelling techniques are discussed as a general framework for further research in the field.
