IntroductionTexting while driving is a significant risk factor for automobile collisions. The use of cell phones is prevalent among young people and commonly reported when they drive.MethodA web-based survey of 861 college student drivers determined how texting was associated with other forms of risky driving, perceptions of risk, and their driving and texting interactions with a significant other.ResultsTexting drivers were more likely to engage in other risky driving behaviors, perceived less risk in texting and driving, felt more immune to traffic risks, and had friends who text and drive. Logistic regression analyses showed that even after adjusting for risky driving behaviors and perceived risk, texting drivers were significantly more likely to do so if they saw their significant other text and drive.ConclusionsTraffic safety campaigns need to address important social influences on this behavior.  相似文献

Although research has indicated that cognitions and situational factors play a role in relationship satisfaction and aggression, few studies have investigated the association between intimate partner violence (IPV) and relationship values. We addressed this gap by measuring college students’ perpetration of and victimization by four types of IPV; namely, physical violence, sexual violence, threats, and psychological aggression over the past year. One-way ANOVAs and multiple regression analyses were used to measure the association between IPV and the endorsement of relationship values. The results suggest that past IPV perpetration and victimization correlated with the current endorsement of relationship values for males more than females. In general, male perpetrators rated relationship values such as security, investment, others’ approval, and daily conflict as less important than non-perpetrators. Although male victimization explained significant variance in security, investment, and others’ approval, the results were somewhat mixed as to whether victimization related to higher or lower ratings of relationship values, with the majority of the results suggesting an inverse correlation between relationship value endorsement and IPV experience. Future research can investigate mediating factors in the relationship between IPV and relationship value endorsement, as well as look at how IPV and relationship values influence decisions concerning relationship maintenance.  相似文献

In a task involving the detection of a predesignated letter during the silent reading of a series of passages, left-brain-damaged aphasic patients and right-brain-damaged patients showed patterns of performance consistent with those of normal individuals. Both of the brain-damaged groups were more likely to detect letters when they were pronounced in a typical way (e.g., g in "ago") than in an atypical way (e.g., g in "through"), suggesting the use of phonological recoding during silent reading. In addition, both of these groups were more likely to detect letters when they occurred in content than in function words, suggesting a differential processing of these word types. Possible differences in the strategies predominantly relied on for phonological recoding and for the differential processing of content and function words by different groups of patients are discussed.  相似文献

Right-handed adults were asked to identify by name bilaterally presented words and pronounceable nonwords. For words in the normal horizontal format, word length (number of letters) affected left visual hemifield (LVF) but not right visual hemifield (RVF) performance in Experiments 1, 2, 3, 5, and 6. This finding was made for words of high and low frequency (Experiment 6) and imageability (Experiment 5). It also held across markedly different levels of overall performance (Experiments 1 and 2), and across different relative positionings of short and long words in the LVF and RVF (Experiment 3). Experiment 4 demonstrated that the variable affecting LVF performance is the number of letters in a word, not its phonological length. For pronounceable nonwords (Experiment 7) and words in unusual formats (Experiment 8), however, length affected both LVF and RVF performance. The characteristics identified for RVF performance in these experiments also hold for the normal reading system. In this (normal) system the absence of length effects for horizontally formatted words is generally taken to reflect the processes involved in lexical access. Length effects in the normal reading system are thought to arise when lexical access for unusually formatted words and for the pronunciation of nonwords requires the short-term storage of information at a graphemic level of analysis. The characteristics of LVF performance indicate that horizontally formatted words presented to the right cerebral hemisphere can only achieve lexical access by a method that requires the short-term storage of graphemic information. This qualitative difference in methods of lexical access applies regardless of whether the right hemisphere is seen as accessing words in the left hemisphere's lexicon or words in a lexicon of its own.  相似文献

IntroductionNumerous studies have focused on the association of dating violence (DV) and alcohol use. However, little research has as yet assessed their co-occurrence in short timeframes.ObjectiveThis study aims to investigate alcohol use in the two hours preceding DV and in the two hours following DV.MethodCollege students (n = 649, 71% females, mean age = 19.8) reported their experience of DV and their hazardous drinking on self-administered questionnaires. They also reported their alcohol use in the two hours preceding – as well as following – a specific DV event (i.e. insult between dating partners).ResultsChi-square tests outline that alcohol use in the two hours preceding an insult is associated with alcohol use in the two hours following an insult. Regressions show that higher scores of hazardous drinking puts students at risk of insulting or being insulted in a context of alcohol use.ConclusionThe findings can contribute to DV prevention programs among college students.  相似文献

This paper provides an overview of a conceptual model that integrates theories of social ecology, minority stress, and community readiness to better understand risk for and outcomes of intimate partner violence (IPV) among LGBTQ+ college students. Additionally, online survey data was collected from a sample of 202 LGBTQ+ students enrolled in 119 colleges across the United States to provide preliminary data on some aspects of the proposed model. Results suggested that students generally thought their campuses were low in readiness to address IPV; that is, students felt that their campuses could do more to address IPV and provide IPV services specific to LGBTQ+ college students. Perceptions of greater campus readiness to address IPV among LGBTQ+ college students was significantly and positively related to a more favorable LGBTQ+ campus climate and a greater sense of campus community. Additionally, IPV victims were more likely to perceive higher levels of campus community readiness than non‐IPV victims. There was no association between IPV perpetration and perceptions of campus community readiness. Greater sense of community was marginally and inversely related to IPV victimization and perpetration. Sense of community and LGBTQ+ campus climate also varied to some extent as a function of region of the country and type of institution. Implications for further development and refinement of the conceptual model, as well as future research applying this model to better understand IPV among sexual minority students are discussed.  相似文献

ABSTRACT

Students’ worries about transitioning to college are correlated with long-term reduced psychological well-being, so we investigated how psychological need satisfaction might mitigate millennials’ worries about college. As parents can support or undermine their children’s basic needs, we also examined the influence of autonomy-supportive and helicopter parenting during the transition. Additionally, we compared these outcomes between first- and continuing-generation students. Incoming college students (N = 355) completed measures of parental relationship need satisfaction, parental involvement, worries about college, and family achievement guilt. Higher need satisfaction in the parental relationship was associated with reduced worries and feelings of achievement guilt for both first- and continuing-generation students. Autonomy-supportive parenting moderated the relationship between autonomy and millennials’ worries about college. Helicopter parenting did not moderate any of the relationships examined in this study but was positively associated with students’ transition worries and achievement guilt. We discuss these findings in the context of self-determination theory.  相似文献

为考察攻击性信息对脆弱型高自尊大学生返回抑制的影响机制,本研究采用线索靶子范式,分别将攻击性及中性词汇作为靶子(实验1)和线索(实验2)呈现。实验1发现,脆弱型和安全型高自尊组对攻击性信息均存在注意捕获,从而使攻击性信息的返回抑制量降低。实验2发现,脆弱型高自尊组对攻击性信息存在注意解除困难,从而使攻击性信息的返回抑制量降低。脆弱型高自尊大学生对攻击性信息存在过多的注意维持,降低了视觉搜索效率,这可是其好发攻击性行为的潜在认知加工机制。  相似文献
