The Good Behavior Game was implemented with four children attending a church-affiliated preschool in efforts to increase concurrent compliance and cooperation. Sessions were conducted individually with each child pair while in free play. The children were given various instructions by “Buddy Bear” (a puppet). Children were praised individually for compliant behavior while noncompliant and inappropriate behaviors were ignored. Further instances in which children complies (i.e., cooperation) were rewarded with tokens make of felt, shaped like happy faced or dinosaurs and placed on a large felt board. If the children earned their criterion levels of tokens, they received animal snacks. Improvements in compliance were noted, with generalization occurring across therapists but not settings. Factors influencing the results and implications of the findings are discussed. 相似文献

In-vehicle information systems (IVIS) have been shown to increase driver workload and cause distraction, both of which are causal factors for accidents. This simulator study evaluates the impact that two prototype ergonomic designs for a smart driving aid have on workload, distraction and driving performance. Scenario complexity was also manipulated as an independent variable. Results showed that real-time delivery of smart driving information did not increase driver workload or adversely affect driver distraction, while also having the positive effect of decreasing mean driving speed in both the simple and complex driving scenarios. Subjective workload was shown to increase with task difficulty, as well as revealing important differences between the two interface designs. The findings are relevant to the development and implementation of smart driving interface designs in the future. 相似文献

Multiple studies have shown an increased accident risk due to telephoning while driving. On the other hand, driving with passengers leads to a decreased accident risk. One explanation is a conversation modulation by passengers in cars which leads to a different conversation pattern which is not so detrimental to driving as that when phoning. A driving simulator study was conducted in order to examine this conversation modulation more closely and to find out more about the factors involved in this modulation, especially about the role of visual information available to the passenger. In a within-subject design the conversational patterns of 33 drivers and passengers in different in-car settings (passenger as usual, passenger without front view or passenger without view of the driver) were compared to a hands-free cell phone and to a hands-free cell phone with additional visual information either about the driving situation or the driver. Participants were instructed to have a naturalistic small-talk with a friend. Results of the drivers’ speaking behavior showed a reduction of speaking while driving. Compared to a conversation partner on the cell phone, a passenger in the car varies his speaking rhythm by speaking more often but shorter. Further analyses showed that this effect is also found with a cell phone when providing the conversation partner additional visual information either about the driving situation or the driver. This latter finding supports the idea that conversation modulation is not triggered by being in the car but by the visual information about the driver’s state and the driving situation. 相似文献

This research examined the development of proceduralised “driving without awareness” in a driving simulator by paying participants to drive a simulated road regularly over 12 weeks of testing. This longitudinal research paradigm is a significant departure from previous studies which have examined drivers in a conscious attentional mode using short experimental sessions or cross-sectional designs comparing expert and novice performance. During each session, participants took two “trips” on the simulated road; sometimes travelling on a “to and from” journey on one half of the road, sometimes traversing the entire road in one direction. A range of measures, including driving performance, vehicle detection, perceptual speed regulation, and hazard reactions were collected. The results showed the development of driving patterns and changes in object detection performance indicative of proceduralised driving. Speed and lane position variability quickly decreased with practice, as did participants’ subjective experiences of driving difficulty. Performance on an embedded detection task appeared to become a proceduralised part of the driving task, becoming highly efficient in later stages of the experiment. The changes in attentional focus and driving performance over time provide new light on previous research findings and allow us to critically re-examine several established models of driver behaviour. 相似文献

Inattentional blindness: looking without seeing 总被引:3,自引:0,他引:3
Arien Mack 《Current directions in psychological science》2003,12(5):180-184
Surprising as it may seem, research shows that we rarely see what we are looking at unless our attention is directed to it. This phenomenon can have serious life-and-death consequences. Although the inextricable link between perceiving and attending was noted long ago by Aristotle, this phenomenon, now called inattentional blindness (IB), only recently has been named and carefully studied. Among the many questions that have been raised about IB are questions about the fate of the clearly visible, yet unseen stimuli, whether any stimuli reliably capture attention, and, if so, what they have in common. Finally, is IB an instance of rapid forgetting, or is it a failure to perceive? 相似文献

Elevated rates of attention deficit and overactivity have been noted previously in samples of institution-reared children. This study examined the hypothesis that inattention/overactivity(I/O) might constitute a specific deprivation syndrome. One hundred and sixty five children adopted at varying ages (e.g., 0–42 months of age) into the UK following severe early deprivation were compared with 52 within-UK adoptees who did not suffer deprivation. The children were rated by teachers and parents on levels of I/O, conduct difficulties, and emotional difficulties using the Revised Rutter Scales. Data were collected at age 6 for the entire sample and at age 4 for the UK adoptees and for the subsample of Romanian children who entered the UK before the age of 2 years. Mean level analyses suggested a significant effect of duration of deprivation on I/O, but not on conduct or emotional difficulties. The effects of duration of deprivation were specific to I/O and were not accounted for by low birth weight, malnutrition, or cognitive impairment. Levels of I/O correlated with attachment disturbances. Furthermore, the effects of duration of deprivation on I/O did not attenuate over time. We conclude that I/O may well constitute an institutional deprivation syndrome, but that the type of attention deficit and overactivity exhibited by these children may present a different clinical picture from that of ordinary varieties of attention deficit disorder or hyperkinetic syndrome. 相似文献

Etiology of Inattention and Hyperactivity/Impulsivity in a Community Sample of Twins with Learning Difficulties 总被引:3,自引:0,他引:3
A community sample of 373 8 to 18 year-old twin pairs in which at least one twin in each pair exhibited a history of learning difficulties was utilized to examine the etiology of inattention and hyperactivity/impulsivity (hyp/imp). Symptoms of attention-deficit/hyperactivity disorder (ADHD) were assessed by the DSM-III Diagnostic Interview for Children and Adolescents. Inattention and hyp/imp composite scores were created based on results of a factor analysis. Results indicated that extreme ADHD scores were almost entirely attributable to genetic influences across several increasingly extreme diagnostic cutoff scores. Extreme inattention scores were also highly heritable whether or not the proband exhibited extreme hyp/imp. In contrast, the heritability of extreme hyp/imp increased as a linear function of the number of inattention symptoms exhibited by the proband. This finding suggests that extreme hyp/imp may be attributable to different etiological influences in individuals with and without extreme inattention. If this result can be replicated in other samples, it would provide evidence that the hyp/imp symptoms exhibited by individuals with Combined Type ADHD and Predominantly Hyp/Imp Type ADHD may be attributable to different etiological influences. 相似文献

This study sought to advance understanding of overconfidence in driving, and its relationship to safety-relevant individual difference factors. We compared the traditional, general above average affect (AAE) in driving ability with an assessment of AAE in relation to compensation for impairments, such as intoxication, fatigue and distraction. General driving and driving impairment AAEs were found to be distinct with unique relationships to illusory control, driver stress, and self-reported unsafe driver behaviors (errors, violations, lapses). Illusory control was associated with driving impairment AAE but not with general driving AAE. Both AAEs were negatively related to dislike of driving but related differently to other criteria. Risk factors related to self-estimation (violations, thrill-seeking) were distinct from factors related to competence relative to peers (aggression). Men scored more highly than women did on both AAEs. Trivia and driving calibration tasks were used to discriminate three aspects of a recent Bayesian belief updating model of overconfidence: overestimation, overplacement (AAE), and overprecision. Findings indicated that overplacement in the calibration tasks was related to AAE, its conceptual equivalent. There was a significant gender difference in overplacement but no gender difference in overprecision. The unique relationships between various types and facets of overconfidence, and driving-relevant individual differences, support the need for tailoring safety interventions to drivers of differing psychological characteristics. 相似文献

Driver distraction is a recognized cause of traffic accidents. Although the well-known guidelines for measuring distraction of secondary in-car tasks were published by the United States National Highway Traffic Safety Administration (NHTSA) in 2013, studies have raised concerns on the accuracy of the method defined in the guidelines, namely criticizing them for basing the diversity of the driver sample on driver age, and for inconsistent between-group results. In fact, it was recently discovered that the NHTSA driving simulator test is susceptible to rather fortuitous results when the participant sample is randomized. This suggests that the results of said test are highly dependent on the selected participants, rather than on the phenomenon being studied, for example, the effects of touch screen size on driver distraction. As an attempt to refine the current guidelines, we set out to study whether a previously proposed new testing method is as susceptible to the effects of participant randomization as the NHTSA method. This new testing method differs from the NHTSA method by two major accounts. First, the new method considers occlusion distance (i.e., how far a driver can drive with their vision covered) rather than age, and second, the new method considers driving in a more complex, and arguably, a more realistic environment than proposed in the NHTSA guidelines. Our results imply that the new method is less susceptible to sample randomization, and that occlusion distance appears a more robust criterion for driver sampling than merely driver age. Our results are applicable in further developing driver distraction guidelines and provide empirical evidence on the effect of individual differences in drivers’ glancing behavior. 相似文献
