We investigated the effects of gender-based social categories (i.e., men, women, boys, and girls) on attitudes about child sexual abuse and individual differences in the use of such categories. In four experiments, we systematically varied perpetrators’ sex and victims’ sex. In three investigations, we assessed personality variables potentially related to participants’ use of these social categories. Across these four experiments, we varied perpetrator-victim relationships (teacher-student, neighbors) and victims’ ages. In experiment one, individuals had the least negative attitude about child sexual abuse involving adult female neighbors and eighth grade male neighbors. In experiment two, we replicated this effect with fifth grade victims and demonstrated that attitudes were moderated by individual differences in intolerance of ambiguity. In experiment three, we again replicated the aforementioned effect while (a) extending this finding to teacher-student relationships with eighth grade adolescent victims and (b) demonstrating the need for cognition was a moderator. In experiment four, we again replicated (a) our perpetrator sex/victim sex interactive effect and (b) need for cognition moderation while also demonstrating that these effects were applicable to fifth grade victims. Methodological limitations as well as clinical and policy implications (e.g., attenuating the underreporting incidents of child sexual abuse) are discussed.  相似文献

A substantial body of research has examined the speed-accuracy tradeoff captured by Fitts’ law, demonstrating increases in movement time that occur as aiming tasks are made more difficult by decreasing target width and/or increasing the distance between targets. Yet, serial aiming movements guided by internal spatial representations, rather than by visual views of targets have not been examined in this manner, and the value of confirmatory feedback via different sensory modalities within this paradigm is unknown. Here we examined goal-directed serial aiming movements (tapping back and forth between two targets), wherein targets were visually unavailable during the task. However, confirmatory feedback (auditory, haptic, visual, and bimodal combinations of each) was delivered upon each target acquisition, in a counterbalanced, within-subjects design. Each participant performed the aiming task with their pointer finger, represented within an immersive virtual environment as a 1 cm white sphere, while wearing a head-mounted display. Despite visual target occlusion, movement times increased in accordance with Fitts’ law. Though Fitts’ law captured performance for each of the sensory feedback conditions, the slopes differed. The effect of increasing difficulty on movement times was least influential in the haptic condition, suggesting more efficient processing of confirmatory haptic feedback during aiming movements guided by internal spatial representations.  相似文献

Anticipatory postural adjustments (APAs) are an integral part of standing balance. Previous research with balance control has shown that adopting an external focus of attention, compared to an internal focus of attention, yields better performance during motor skills. Despite the importance of APAs, especially among older adults, and the potential benefits of adopting an external focus of attention, studies investigating methods for improving APAs are limited. The aim of this study was to compare behavioral, kinematic and APAs measures while adopting different foci of attention among young and older adults when performing a lower extremity Fitts’ task. Ten young adults (mean age 24 years ± 4.37) and ten older adults (mean age 75 years ± 5.85) performed a lower-extremity reaching task (Fitts’ task) while adopting an external focus (focus on target) and an internal focus (focus on limb) in a within-subject design. A motion capture system was used to record participants’ movement data. Custom software derived movement time (MT), peak velocity (PV), time to peak velocity (ttPV) and variability at target (SDT). Electromyography (EMG) was used to determine APAs onset and magnitude. The findings showed that an external focus of attention led to significantly shorter MT, higher PV, shorter ttPV and more accuracy when reaching the target (SDT) for both age groups. Also, EMG results showed that, with an external focus, APAs onset occurred earlier and APAs magnitude was more efficient. As predicted by Fitts’ Law, participants spent more time executing movements to targets with higher indices of difficulty. Older adults compared to young adults were more adversely affected by the increase of difficulty of the Fitts’ task, specifically, on measures of APAs. In conclusion, adopting an external focus of attention led to better overall movement performance when performing a lower extremity Fitts’ task. The task used in the present study can distinguish between APAs for older and young adults. We recommend that future studies expand on our findings in order to establish a performance-based objective measure of APAs to assess clinical interventions for postural control impairment.  相似文献

Medically assisted procreation includes techniques that may allow infertile couples to procreate. However, the application of 2011 bioethics law reveals lots of paradox and high-risk behaviors which arouse the question of the relevance and advisable aspect of its opening to all women.  相似文献

The announcement of the cancer diagnosis and his treatment is an important moment in the set up of the doctor–patient relationship. The law of contracts has long governed the relationship between the doctor and the patient. But the legislature clearly demonstrated its will to consider the patient as full actor of his health, leaving the regime of medical decision, the shared decision. This shared decision is based on an obligation to inform the patient on his health and knows many exceptions (minor patients or adults under guardianship, emergency). In Oncology, the medical decision is a decision coordinated between doctors in the multidisciplinary consultation meetings. This decision is considered as a guarantee of the quality of the medical care. It does not preclude the time of the doctor–patient relationship.  相似文献

针对2004年<医学与哲学>第7期孙福川教授<对"人造美人"医学的十大人文拷问>一文,提出自己的观点,认为"人造美人"是临床医疗行为,其出现并没有偏离医学的目的,"人造美人"的法律主体地位应是患者,因人造美人而出现的纠纷可以适用于处理医疗纠纷的相关法律、法规,同时造美广告也是医疗广告.  相似文献

虚假医药广告问题与对策   总被引:6,自引:1,他引:5  
夸大其词、耸人听闻的虚假广告给人民群众造成了巨大的身心伤害,对社会的侵害与污染极为严重。这些非法广告之所以存在,一方面是相关法律法规制定不完善和执行不严格,一方面是医药卫生领域和广告传媒领域职业道德的缺失。医药信息关系群众的生命安全,所以清除带有虚假成分的医药广告刻不容缓。  相似文献

An interesting fact about customary international law is that the only way you can propose an amendment to it is by breaking it. How can that be differentiated from plain law-breaking? What moral standards might apply to that sort of international conduct? I propose we use ones analogous to the ordinary standards for distinguishing civil disobedients from ordinary law-breakers: would-be law-makers, like civil disobedients, must break the law openly; they must accept the legal consequences of doing so; and they must be prepared to have the same rules applied to them as everyone else.  相似文献

Abstract. Many question whether Islam and science can be compatible. In the first six hundred years of Islam, Muslims addressed all fields of knowledge available to them with unprecedented zeal and contributed immensely to the knowledge that became the precursor of the Renaissance in Europe. The Tatar invasion in the thirteenth century and the total destruction of Baghdad, the Muslim capital of knowledge and science, followed by the crusades, the ensuing hostility between East and West, and Western colonialism of Muslim countries led to a distrust of all knowledge emanating from the West. Such distrust closed the doors to ijtihad, a dynamic method in Islamic jurisprudence for addressing change, new demands, and new acquired knowledge, even though the Qur'an challenges Muslims to think, contemplate, understand, comprehend, and examine everything around them—tasks that bring humankind closer to God as they find methods to apply God's laws of justice and equity to the benefit of all humankind. Islam is the religion of yusr (ease) and not ‘usr (hardship). The creation of the world was for human benefit and use. Innovation for such beneficial use and application is a must.  相似文献

Piéron's law, which formulates the effect of the signal intensity i on the mean or the median reaction time (MRT) as a power function, MRT=R+i-βC, in which R, β and C are positive parameters, is of much interest in the simple reaction time literature. In particular, consistent estimates of β are obtained. However, this law offers no information regarding the effect of the signal intensity on other aspects of the reaction time distribution. In addition, the background intensity, which also has some impact on the detectability of the signal, is not considered in Piéron's law. In this paper, we generalize Piéron's law based on the above comments. That is, we assume that both β and C are functions of the background intensity and of the percentile rank. We then investigate from a theoretical viewpoint some possible functional forms of β and C, with a special emphasis on the dependency of β on the background intensity. It is shown that the so-called “Fechner-Thurstone-type representation” forces β and C to be “separable.” If we further assume a near-miss to Weber's law-type representation, then the functional form of β can be determined.  相似文献
