The aim of this paper was to explore effects of specific emotions on subjective judgment, driving performance, and perceived workload. The traditional driving behavior research has focused on cognitive aspects such as attention, judgment, and decision making. Psychological findings have indicated that affective states also play a critical role in a user’s rational, functional, and intelligent behaviors. Most applied emotion research has concentrated on simple valence and arousal dimensions. However, recent findings have indicated that different emotions may have different impacts, even though they belong to the same valence or arousal. To identify more specific affective effects, seventy undergraduate participants drove in a vehicle simulator under three different road conditions, with one of the following induced affective states: anger, fear, happiness, or neutral. We measured their subjective judgment of driving confidence, risk perception, and safety level after affect induction; four types of driving errors: Lane Keeping, Traffic Rules, Aggressive Driving, and Collision while driving; and the electronic NASA-TLX after driving. Induced anger clearly showed negative effects on subjective safety level and led to degraded driving performance compared to neutral and fear. Happiness also showed degraded driving performance compared to neutral and fear. Fear did not have any significant effect on subjective judgment, driving performance, or perceived workload. Results suggest that we may need to take emotions and affect into account to construct a naturalistic and generic driving behavior model. To this end, a specific-affect approach is needed, beyond the sheer valence and arousal dimensions. Given that workload results are similar across affective states, examining affective effects may also require a different approach than just the perceived workload framework. The present work is expected to guide emotion detection research and help develop an emotion regulation model and adaptive interfaces for drivers. 相似文献

This study tested an affective events theory (AET) model in the Oxford House network of recovery homes. Residents’ congruence with their home (P–E fit) was hypothesized to directly influence behavior that supported the house and other residents—citizenship behavior. We further hypothesized P–E fit would be related to member intentions to leave, with attitudes toward the home mediating that relationship. To assess this, we administered a cross‐sectional national survey to 296 residents of 83 randomly selected Oxford Houses. Although the AET model demonstrated good fit with the data, an alternative model fit better. This alternative model suggested an additional indirect relationship between P–E fit and citizenship mediated by attitudes. Results suggested affective experiences such as feeling like one fits with a community may influence engagement and disengagement. There appears to be a direct influence of fit on citizenship behavior and an indirect influence of fit through recovery home attitudes on both citizenship and intentions to leave the home. We conclude affective experiences could be important for community engagement and disengagement but AET may need to integrate cognitive dissonance theory. 相似文献

Affective differentiation is the degree to which positive affect (PA) and negative affect (NA) are uncorrelated. The dynamic model of affect (Zautra, Potter, & Reich, 1997) posits that the link between PA and NA should be stronger when stress is high. Because neuroticism relates to more negative everyday stress perceptions and therefore higher daily stress, we hypothesized that neuroticism should be associated with lower affective differentiation on a daily basis. We examined how neuroticism impacts momentary affective differentiation in undergraduate students (n = 126) using an experience sampling design with mood monitored four times daily for one week. We found that neuroticism moderates the within-person relationship between PA and NA: those who are higher in neuroticism experience less affective differentiation. This effect was not mediated or moderated by recent major life stress. We replicated the main finding in two subsequent samples (n = 102 and n = 120, respectively), and thus present the first large set of studies to demonstrate consistently that neuroticism moderates the within-person link between PA and NA. 相似文献

The aim of this study was to investigate the patterns of contralateral motor overflow (i.e. mirror movement) between the homologous body parts on the right and left side, in stroke patients during single-finger and multi-finger maximum force production tasks. Forty subjects, including stroke (n = 20) and normal subjects (n = 20), participated in this study. The stroke subjects maximally pressed force sensors with their fingers in a flexed position using a single (index, middle, ring, or little) or all fingers (all 4 fingers) using the impaired (IH) or unimpaired (UIH) hand, while the non-patient subjects used their right hands for the same tasks. The maximal voluntary forces in the ipsilateral and unintended pressing forces of each contralateral finger were recorded during the tasks. The magnitude of motor overflow to the contralateral side was calculated using the index of contralateral independence (CI). During the single finger tasks, the finger CI was significantly decreased in the UIH (91%) compared with that in the IH (99%) or normal hands (99%). Likewise, the multiple finger tasks showed that the CI was significantly lower in the UIH (84%) compared with that in the IH (96%) or normal hands (99%). However, the maximal forces were significantly lower in the IH relative to those in the UIH and normal hands. These data demonstrate that stroke patients have greater motor overflow from the UIH to the IH. 相似文献

Theories of adolescent behaviour attribute increases in risk-taking and sensation-seeking in this age group to a heightened sensitivity to emotional stimuli on the one hand and a relatively immature cognitive control system on the other hand. However, little research has outlined to what extent relevant and irrelevant emotional stimuli bias the imbalance between affective processing and cognitive control. Thirty-three adolescents (19 females, aged 12–14) and 37 adults (18 females, aged 18–29) completed two attentional conditions of an emotional face working memory (WM) 0-back/2-back task. Participants were asked to attend to the emotional facial expression in the “relevant” emotion condition, and to the gender of the face in the “irrelevant” condition. The results revealed a WM improvement for happy faces in the relevant condition in both age groups, and an impairment for irrelevant happy faces in adolescents, but not adults. Furthermore, the difference between both attentional conditions for happy faces was larger in adolescents than adults. Results are discussed within the framework of theories of adolescent behaviour. 相似文献

In this study, we investigated motor and cognitive procedural learning in typically developing children aged 8–12 years with a serial reaction time (SRT) task and a probabilistic classification learning (PCL) task. The aims were to replicate and extend the results of previous SRT studies, to investigate PCL in school-aged children, to explore the contribution of declarative knowledge to SRT and PCL performance, to explore the strategies used by children in the PCL task via a mathematical model, and to see whether performances obtained in motor and cognitive tasks correlated. The results showed similar learning effects in the three age groups in the SRT and in the first half of the PCL tasks. Participants did not develop explicit knowledge in the SRT task whereas declarative knowledge of the cue–outcome associations correlated with the performances in the second half of the PCL task, suggesting a participation of explicit knowledge after some time of exposure in PCL. An increasing proportion of the optimal strategy use with increasing age was observed in the PCL task. Finally, no correlation appeared between cognitive and motor performance. In conclusion, we extended the hypothesis of age invariance from motor to cognitive procedural learning, which had not been done previously. The ability to adopt more efficient learning strategies with age may rely on the maturation of the fronto-striatal loops. The lack of correlation between performance in the SRT task and the first part of the PCL task suggests dissociable developmental trajectories within the procedural memory system. 相似文献

Linguistic relativity—the idea that language affects thought by way of its grammatical categorizations—has been controversially debated for decades. One of the contested cases is the grammatical gender of nouns, which is claimed to affect how their referents are conceptualized (i.e., as rather female or male in congruence with the grammatical gender of the noun), especially when used allegorically. But is this association strong enough to be detected in implicit measures, and, if so, can we disentangle effects of grammatical gender and allegorical association? Three experiments with native speakers of German tackled these questions. They revealed a gender congruency effect on allegorically used nouns, but this effect was stronger with an explicit measure (assignment of biological sex) than with an implicit measure (Extrinsic Affective Simon Task) and disappeared in the implicit measure when grammatical gender and allegorical associations were set into contrast. Taken together, these findings indicate that the observed congruency effect was driven by the association of nouns with personifications rather than by their grammatical gender. In conclusion, we also discuss implications of these findings for linguistic relativity. 相似文献

Understanding and modeling the influence of mobile phone use on pedestrian behaviour is important for several safety and performance evaluations. Mobile phone use affects pedestrian perception of the surrounding traffic environment and reduces situation awareness. This study investigates the effect of distraction due to mobile phone use (i.e., visual and auditory) on pedestrian reaction time to the pedestrian signal. Traffic video data was collected from four crosswalks in Canada and China. A multilevel mixed-effects accelerated failure time (AFT) approach is used to model pedestrian reaction times, with random intercepts capturing the clustered-specific (countries) heterogeneity. Potential reaction time influencing factors were investigated, including pedestrian demographic attributes, distraction characteristics, and environment-related parameters. Results show that pedestrian reaction times were longer in Canada than in China under the non-distraction and distraction conditions. The auditory and visual distractions increase pedestrian reaction time by 67% and 50% on average, respectively. Pedestrian reactions were slower at road segment crosswalks compared to intersection crosswalks, at higher distraction durations, and for males aged over 40 compared to other pedestrians. Moreover, pedestrian reactions were faster at higher traffic awareness levels. 相似文献

This article uses walking ethnography to approach the memoryscape of Stockton, a peninsula settlement opposite the city of Newcastle, Australia. As new residents of the city, we walked the memoryscape of Stockton together and with friends and family seeking encounters with the material objects of local memory as an entry into place. Stockton's memoryscape is full of objects gravid with deeply localised meanings. In some cases, our encounters have stimulated inquiry into documented histories and stories behind the objects, however we remain primarily concerned with the prospects, and limitations, of encountering the memoryscape ‘fresh’. From these experiences we adopt a three-part argument. First, Stockton's memoryscape exhibits a shared local identity based on defiance evident in three groups of memorial objects: (i) unintentional memorials created by the unstable landscape (ii) DIY memorials made by local residents, and (iii) monuments sanctioned by local authorities. Second, Stockton's memoryscape remains powerfully rooted in place. It is vibrant, defying digitisation, defying displacement and re-placement. Stockton's memorials and monuments need to be found, encountered, shared in situ on the unstable ground of ballast and sinking sand. Third, walking ethnography restricted to a bounded area, mode of mobility (walking), theme (memorials), and epistemology (encounter with objects) generates rich ethnographic material on place, even without expert knowledge of the past. These experiments in walking and encountering objects in the vernacular memoryscape animated our imagination even with only limited detail on what to remember and how to feel about it. This offers a contribution to interdisciplinary research on the affective power of found material objects in ethnographic analysis. 相似文献
