Patterns in perceived crash risk among male and female drivers with and without substantial cycling experience

Perceived risk of crashes is generally higher in female than in male cyclists. No study has assessed whether these gender differences only apply to riding bicycles. Using an online risk assessment task and survey, this study (a) tested the hypothesis that compared to men, women perceive higher risks, irrespective of traffic mode and (b) explored gender differences in the predictors of perceived risk. Data were analysed from 595 driver licence holders in Australia: 444 who cycled regularly, termed ‘cyclists’ from here on (31% women) and 151 regular drivers who did not (63% women), who are referred to as ‘drivers’. Cyclists in their role as cyclists and drivers in their role as drivers (traffic role) were instructed to imagine being in a specified traffic scenario and to assess crash likelihood. Each of 6 traffic scenarios was presented twice but differing in configuration: a violating car and a violating bicycle. A mixed ANOVA, with rated probability of a crash as the dependent variable, gender and traffic role as grouping factors, and configuration as the repeated measure, resulted in a main effect of configuration, showing that both drivers and cyclists perceived higher levels of risk of violating cars than of violating bicycles (η_p2 = 0.34). The interaction of traffic role and configuration showed this difference to be smaller for drivers than for cyclists (η_p2 = 0.18). This suggests that drivers are aware of the car’s high injury potential in crashes with cyclists. The main effect of gender showed that irrespective of traffic role, women perceived higher risk than men, which supported the hypothesis that gender differences are not limited to cycling (η_p2 = 0.03). The main effect of traffic role was not significant.For the predictors of perceived risk, ANOVA showed main effects for traffic role and gender, with small effect sizes (from η_p2 = 0.02 to η_p2 = 0.03). Cyclists were more confident, less inattentive and more in favour of stricter laws. Women felt less skilled and were more concerned about risks. None of the interactions between gender and traffic role were significant, which lent further support to the hypothesis that gender differences were a general rather than a cycling specific characteristic. Thus, perceived risk does not differ between women who regularly cycle and those who do not. These findings may inform interventions about the role of perceived risk in the uptake of cycling.     

词汇预测性对中文高、低阅读技能儿童眼动行为的影响

操纵目标词的预测性、词频和阅读技能水平,考察句子阅读中词汇预测性对高、低阅读技能儿童眼动行为的影响,揭示其在儿童阅读发展中的作用。结果显示：儿童对高预测词的跳读率更高、注视时间更短,且预测性与词频交互影响跳读率和注视时间;预测性对高阅读技能儿童早期的跳读率影响更大,而对低阅读技能儿童晚期的再阅读时间具有更大影响。结果表明：词汇预测性影响儿童阅读的眼动行为和词汇加工,且作用大小和发生时程受阅读技能调节。     

精诚合一:医学哲学事业的永恒主题

医学哲学事业的价值在于发现并弘扬医学的基本精神。“精诚合一”是医学亘古不变的基本精神。当代医学哲学研究的任务是揭示医学的“精诚合一”特征及其深刻内涵,注重“精”与“诚”的有机结合,批判现实医疗活动和理论研究在“精”、“诚”问题上的片面,弘扬医学的基本精神。     

职业评定量表(VIESA)的信度和效度研究

根据D.E.Super的职业发展理论,职业选择的成熟与发展一般分为五个阶段,中学生正处在从探索到成熟的重要转变期。本研究以美国大学测验中心的职业分类系统为基础,以职业评定量表VIESA为工具和对象,对北京市第六十五中学的179名高中三年级学生和北京师范大学心理学系的55名二年级学生进行了施测,检验了量表的信度和效度。量表的信度指标基本在.70以上,构想效度良好,以专业满意感为效标的效标效度达到显著水平。     

组织中的政治技能及相关研究

政治技能是个体在工作中影响他人以实现组织目标的能力,对个体的工作绩效和某些工作态度、缓解工作中压力带来的紧张感等具有一定的作用。个体的洞察力、控制、亲和力、主动影响及发展经验被视为政治技能的影响因素,通过实践练习、替代学习等方法可实现政治技能的培训和开发。在未来的研究中,对政治技能概念的理解、测量多源性等方面的问题还需要进一步的探讨     

政治与关系视角的员工职业发展影响因素探讨

通过对16家制造型企业中的343个员工、662个同事及343个直接领导的配对数据进行实证分析,文章探讨了员工的组织政治技能、政治知觉,以及他们与直接上司的关系对于员工职业发展的关系。多层线性分析模型（HLM）结果表明：员工的政治技能有助于促进其与领导之间形成良好的关系（guanxi）,并籍此积极影响个人在组织中的职业发展,员工－领导关系是政治技能与职业发展之间的中介变量。另外,组织政治知觉影响政治技能对领导关系的作用,在政治氛围浓重的组织中,员工－领导关系更易受到员工政治技能的影响

TEACHING BETWEEN-CLASS generalization OF TOY PLAY BEHAVIOR TO HANDICAPPED CHILDREN

In this study, young children with severe and moderate handicaps were taught to generalize play responses. A multiple baseline across responses design, replicated with four children, was used to assessthe effects of generalization training within four sets of toys on generalization to untrained toys from four other sets. The responses taught were unique for each set of toys. Acrossthe four participants, training to generalize within-toy sets resulted in complete between-class generalization in 11 sets, partial generalization in 3 sets, and no generalization in 2 sets. No generalization occurred to another class of toys that differed fromthe previous sets in that they produced a reaction tothe play movement (e.g., pianos). Implications for conducting research using strategies based on class interrelationships in training contexts are discussed.     

Effects of situational demand in the role-play assessment of assertive behavior

Assertive and nonassertive subjects role played responses to interpersonal situations of known response difficulty in which various types of assertions were appropriate to evaluate the interactive effects of demand and difficulty on assertive performance. Subjects responded as they normally would (low demand) and as if they had just finished an extensive assertive training program (high demand). Role-play data, rated for overall assertion, revealed that (a) subjects were more assertive under high than low-demand; (b) assertive performance varied with situational difficulty; and (c) self-reports of assertive ability predicted behavior only when role-play situations were easy or demand low, and high demand had preceded low demand. It was concluded that assertive performance is strongly influenced by situational and cognitive variables, that self-reports predict behavior only in specific assessment circumstances, and that role plays tend to measure maximal, rather than typical, performance. These findings are discussed in terms of their implications concerning the validity of role-play assessment procedures.An earlier version of this paper was presented at the annual convention of the Association for Advancement of Behavior Therapy, Toronto, Canada, November 1981.     

Primes, contingent attention, and training: effects on a child's motor behavior

The use of primes, contingent attention, and training sessions to assess a child's engagement and skill in six large motor activities was examined using a combination reversal and multiple-baseline design. Assessment was based on four levels: proximity to equipment, touching equipment, unskilled participation, and skilled participation. Before training, priming (suggestion to the child) was more effective than contingent attention for increasing the subject's engagement (but not skill) in five activities and for increasing skilled participation in one activity. Training of four activities in the natural environment effectively increased the subject's skill level in five activities. Thus, training appeared to generalize to one of these five activities in this setting and also to skillfully executed stair climbing in an adjoining setting. After training, primes and contingent attention were sufficient to maintain both the subject's skill level and engagement in all activities. Postchecks in the same setting the following semester with different teachers revealed only slight increases in participation, as compared to previous baselines, but all participation was at the skilled level. Social interaction, which was not experimentally manipulated, did not systematically vary in relation to changes in experimental conditions.
