Reward-related processes are impaired in children with ADHD. Whether these deficits can be ascribed to an aversion to delay or to an altered responsiveness to magnitude, frequency, valence, or the probability of rewards still needs to be explored. In the present study, children with ADHD and normal controls aged 7 to 10 years performed a simple probabilistic discounting task. They had to choose between alternatives where the magnitude of rewards was inversely related to the probability of outcomes. As a result, children with ADHD opted more frequently for less likely but larger rewards than normal controls. Shifts of the response category after positive or negative feedback, however, occurred as often in children with ADHD as in control children. In children with ADHD, the frequency of risky choices was correlated with neuropsychological measures of response time variability but unrelated to measures of inhibitory control. It is concluded that the tendency to select less likely but larger rewards possibly represents a separate facet of dysfunctional reward processing, independent of delay aversion or altered responsiveness to feedback. 相似文献

Although word recognition deficits (WRD) are a known cause of reading comprehension deficits (RCD), other contributions to RCD, including executive function (EF), have not been fully explored. We examined the contribution of EF (working memory and planning), along with attention, decoding, fluency, and vocabulary to reading comprehension in 60 children (including 16 WRD and 10 RCD), ages 9–15 years. After controlling for commonly accepted contributors to reading comprehension (i.e., attention, decoding skills, fluency, and vocabulary), EF continued to make a significant contribution to reading comprehension but not to word recognition skills. These findings highlight the need for consideration of the role of EF in RCD. 相似文献

ABSTRACTThe interaction between interfacial dislocations and γ/γ′ interface is critical to the high temperature creep properties of single crystal superalloys. However, only a few studies have paid attention to the detailed structure such as local interfacial morphologies and the elemental distribution around interfacial dislocations. In this paper, the interfacial protrusions and related dislocations in a single crystal superalloy after creep at high temperature – low stress have been investigated in detail. It is found that the morphology and size of the interfacial protrusions remain almost the same during the early and middle stages of high temperature creep, which indicates a local equilibrium at the interfacial protrusions. Steps at different height are formed at the γ/γ′ interface at the initial stage of high temperature creep since dislocations could move along the γ/γ′ interface, which indicates that dislocation motion at different creep stage may affect the morphology of γ/γ′ interface. 相似文献

The average velocities of screw dislocations in Ni 3 Al single crystals have been directly measured as a function of resolved shear stress (RSS) and orientation in the temperature domain of the flow stress anomaly using the etch-pit technique. The velocity was found to be extremely sensitive to the RSS in all cases. In contrast with ordinary metals, the screw dislocation velocities in Ni 3 Al show anomalous behaviour; under a constant RSS, the velocities decrease dramatically with increasing temperature. Furthermore, the velocities and the tension-compression asymmetry of the velocities depend on the orientation of applied stress. 相似文献

This study explored how early childhood teachers (n=5) and young children (n=174) (age range 7 to 8 years; males = 81; females = 93) in two primary schools constructed and interpreted the right to HIV/AIDS education. Data were captured using individual interviews with teachers and group interviews with young children. Analysis of the data showed that teachers viewed young children's right to health information positively but did not consider the right to sexual information. Teachers operated within discourses which upheld the image of the child as innocent requiring protection from sexual knowledge. Children's perceptions of their rights to knowledge of sex in HIV/AIDS education showed ambiguity. Some accepted the right to know whilst others felt that knowledge about HIV/AIDS was inconsistent with childhood innocence. 相似文献

The study examined the success of a group based behavioural intervention with Nigerian youths aimed at reducing the risk of contracting and spreading HIV/AIDS and other sexually transmitted illness (STI). Participants were 147 youths (males=75, females=72, age range 5 to 24 years). The study explored the influence of motivational factors (self efficacy), attitudinal factors (perceived personal risk), knowledge (instrumental knowledge of AIDS) and behavioural factors (refusal of high-risk behaviour) in predicting condom use amongst youth participating in a group-based HIV prevention intervention. Findings indicated that the intervention program reliably predicted participants' attitudinal dispositions to high risk heterosexual behaviour. Instrumental knowledge of HIV/AIDS, perceived self-efficacy, perceived personal risk of HIV/AIDS and refusal of risk behaviour were significant predictors of condom use. 相似文献

The aim of this article is to discuss the current legislation, and power structures in and between different levels of the Church of Sweden in terms of church–state relations and secularisation, with the help of theories from sociology of religion and ecclesiology drawn from José Casanova, Grace Davie and Avery Dulles. With themes from Lutheran theology, including the two regiments and the common priesthood of all believers, we analyse the current legislation and power structures from the perspective of the so-called ‘dual line of responsibility’. The underlying hypothesis is that the structures of the former state church are still deciding the power structures in the Church of Sweden. This creates obscurity concerning the role of the church in public society and negatively affects the ecclesiastical development of the church now that it has lost its earlier status as a state church. 相似文献

Abstract This article questions the adequacy of the philosophical category of realism in characterizing Rheticus' endorsement of Copernicus' astronomy. Rheticus and Osiander agree that the human intellect is restricted in its aspirations to truth, resulting in a condition of “causal ignorance” regarding the celestial phenomena on Rheticus' part. Copernicus' pupil advances trust in the most true hypothesis of the motion of the earth without postulating its absolute truth. Causal knowledge waits after Resurrection. In line with Luther's comment on Genesis 1:14, Rheticus ascribes a theological meaningfulness to the pursuit of mathematics, alerting the astronomer to his immortal soul and divine creation. 相似文献

Abstract This paper explores some of the therapeutic issues which arise when working with sexually abused clients. It is suggested that both the client and the therapist may at moments take any of the three positions in the Oedipal triangle and that the mother, father and child status are interchangeable in the transference and counter-transference. It is also suggested that the Oedipus myth represents the failure of a family to contain sexual and murderous passions. I describe a Hindu myth which takes a similar triangle of passion but illustrates how containment is possible. It is proposed that this implies we need to re-evaluate the presence of the erotic in therapy in a more positive light. It is further suggested that the sexually abused client needs to experience the containment of passion if a healing process is to occur. 相似文献
