Research suggests that personality may change due to important life events, such as psychotherapy, and that personality and attitudes may predict treatment progress. Longitudinal data in a community mental health clinic showed positive changes in Emotional Stability, Hope, Gratitude, and Motivation during the course of psychotherapy. The static approach relating baseline personality and attitudes to treatment progress did not yield fruitful results. The dynamic approach was more effective, in which we treated personality and attitudes as malleable and used changes in these variables as predictors of progress. Treatment progress correlated with an increase in Emotional Stability. Positive changes in general life attitudes (Hope, Gratitude, Quality of Life) more so than therapy-specific attitudes (Motivation, Working Alliance) predicted symptom reduction. 相似文献

There is increasing evidence that indicates a critical transition period for the maturation of postural control from the ages of 6–7 years. Some studies suggest that this transitional period may be explained by a change from a ballistic toward a sensory strategy, but the cause remains unknown. The purpose of this study was to investigate the influence of the transition period on dynamic postural control in a natural self-initiated leaning task under different sensory conditions. We evaluated the center of pressure (COP) displacement during maximum leaning in four directions (forward, backward, rightward, leftward) under three sensory conditions (eyes open, eyes closed and eyes closed standing on a foam). Three groups were tested: young children (4 years old), older children (8–10 years old) and adults (21–42 years old). The maximum COP excursion along the anteroposterior and mediolateral axes and the COP amplitude were analyzed. Young children showed smaller maximum anteroposterior and mediolateral COP excursion than other groups. Older children also exhibited a significantly smaller maximum excursion along the mediolateral direction but performed similar to adults along the anteroposterior direction. In a similar manner, the analysis of the COP amplitude did not indicate any differences between the groups along the anteroposterior axis. In contrast, along the mediolateral axis, the results showed developmental differences. Furthermore, the effect of sensory conditions was similar across the children's groups. Our results suggest an important plasticity period for the maturation of postural control mechanisms. Notably, our findings support the idea that the postural mechanisms controlling the anteroposterior axis reach maturity before the mechanisms involved in controlling the mediolateral axis. 相似文献

Harmony and conservative extension are two criteria proposed to discern between acceptable and unacceptable rules. Despite some interesting works in this field, the exact relation between them is still not clear. In this article, some standard counterexamples to the equivalence between them are summarized, and a recent formulation of the notion of stability is used to express a more refined conjecture about their relation. Then Prawitz's proposal of a counterexample based on the truth predicate to this refined conjecture is shown to rest on dubious assumptions. As a consequence, two new counterexamples are proposed: one uses the extension of logic with a small amount of arithmetic, while the other uses the extension of a small fragment of arithmetic with a problematic operator defined by Peano. It is argued that both these new counterexamples work fine to reject the conjecture and that the last one works also as a rejection of harmony as a complete criterion of acceptability of rules. 相似文献

Driver distraction due to cellular phone usage is a major contributing factor to road crashes. This study compares the effects of conversational cognitive tasks using hands-free cellular phone on driving performance under three distraction conditions: (1) no distraction (no cellular conversation), (2) normal conversation (non-emotional cellular conversation), and (3) seven-level mathematical calculations. A car-following scenario was implemented using a driving simulator. Thirty young drivers with an average age of 24.1 years maintained a constant speed and distance between the subject vehicle and a leading vehicle on the driving simulator, and then respond to the leading vehicle’s emergency stop. The driving performances were assessed by collecting and statistically analyzing several variables of maneuver stability: the drivers’ brake reaction times, driving speed fluctuation, car-following distance undulation, and car-following time-headway undulation. The results revealed that normal conversation on a hands-free cellular phone impaired driving performance. The degree of impairment caused by normal calculation was equivalent to the distraction caused by Level 3 mathematical calculations according to the seven-level calculation baseline. The calculation difficulty of Level 3 is one double-digit figure plus a single-digit figure, and non-carry addition mental arithmetic is required, e.g., 44 + 4. The results indicated that an increase in the level of complexity of the calculation task was associated with an increase in brake reaction time. The seven-level calculation-task baseline could be applied to measure additional distraction effects on driving performance for further comparison. 相似文献

Arguments from stability for liberal nationalism rely on considerations about conditions for the feasibility or stability of liberal political ideals and factual claims about the circumstances under which these conditions are fulfilled in order to argue for nationalist conclusions. Such reliance on factual claims has been criticised by among others G. A. Cohen in other contexts as ideological reifications of social reality. In order to assess whether arguments from stability within liberal nationalism, especially as formulated by David Miller, are vulnerable to a comparable critique, the rationale for their reliance on factual claims is discussed on the basis of a number of concerns in John Rawls’s political liberalism. The concern with stability in liberal nationalism differs from stability in Rawls’s work, mainly because of the stronger non-ideal or ‘realist’ focus of the former. In so far as the ‘realism’ of arguments from stability for liberal nationalism is recognized, they are not vulnerable to the reification charge. But if the arguments are construed as realist, this at the same time makes for other tensions within liberal nationalism. 相似文献

依恋内部工作模式(internal working model)是一种认知/情感性的构造,是在婴儿/孩子与父母行为交互作用的过程中发展起来的对他人和自我的一种心理表征。Bowlby的内部工作模式的概念为理解依恋行为的发展提供了方法,是依恋研究工作的进步。该文从内部工作模式的性质、内部工作模式的结构和其稳定性的研究对内部工作模式进行了较为详细的介绍,详细论述了在发展心理学和社会心理学不同理论背景下的几种可能的结构,进一步分析了内部工作模式的稳定性和变化的机制及其影响因素,并对今后内部工作模式概念的发展和可能的不同类型的内部工作模型结构的存在进行了思考和探索。特别的提出,随着儿童青少年的成长,人际关系的不断复杂化,个体可能在自身的依恋模式基础上分别分化出不同类型的工作模式结构,对这一理论构想进行深入研究将有可能揭示内部工作模式的个体差异性。 相似文献
