The young brain is particularly vulnerable to injury due to inherent physiological and developmental factors, and even mild forms of traumatic brain injury (mTBI) can sometimes result in cognitive and behavioural difficulties. Despite the high prevalence of paediatric mTBI, little is known of its impact on children's social functioning. Parent–child relationships represent the centre of young children's social environments and are therefore ideal contexts for studying the potential effects of mTBI on children's social functioning. The aim of this study was to assess the quality of parent–child interactions after mTBI using observational assessment methods and parental report. The sample included 130 children (18–60 months at recruitment) divided into three groups: children with uncomplicated mTBI (= 47), children with orthopaedic injury (OI,= 27), and non‐injured children (NI,= 56). The quality of parent–child interactions was assessed 6 months post‐injury using the Mutually Responsive Orientation (MRO) scale, an observational measure which focuses on the dyadic nature of parent–child exchanges, and the Parental Stress Index questionnaire (Parent‐Child Dysfunctional Interaction (PCDI) domain). Significant differences with medium effect sizes were found between the mTBI group and the NI group on the MRO, but not between the OI group and the other two groups. PCDI scores did not differ across groups, suggesting that observational measures may be more sensitive to changes in parent–child interactions after TBI. The current findings have implications for children's post‐injury social development and highlight the importance of monitoring social outcomes even after minor head injuries.  相似文献

This study tested the hypothesized directional relationship that college students (N = 717; 10.1% response rate to an online survey) who score higher on measures of insecure attachment and social media practices would have lower relationship development quality scores. Structural equation modeling results indicated that participants with greater insecure attachment had lower relationship development quality (large effect size), whereas individuals with greater social media practices had higher relationship development quality scores. Implications for counselors are presented.  相似文献

Two modes of reasoning are used by humans – the `theoretical' (formal) and the `empirical' (non-formal), the first operating with inside-the-syllogism information, the second utilising out-of-the-syllogism information. Cross-cultural research (since Lévy-Bruhl, and especially after Luria) and developmental research (since Piaget) discovered respectively that members of `traditional' societies and children up to a certain age are able to operate only in the empirical mode.The paper brings together diverse discussions about usage of these modes in actual discourse (Ennis, Johnson-Laird, Moore, Olson, Ong, etc.). It concentrates on contradictory opinions as to whether contemporary individuals after they acquire the formal mode preserve and utilise the empirical mode. In this connection it discusses results of neurological experiments investigating performance in solving syllogisms under conditions of transitory suppression of the left or the right hemisphere (Deglin et al.) which demonstrated that one and the same person, depending on which hemisphere is suppressed, uses both strategies. The activated right hemisphere utilizes the `empirical' pattern, the activated left hemisphere utilizes the `logical' pattern. Thus both mechanisms of reasoning are present in the brain simultaneously, but each of them is controlled by different hemispheres.  相似文献

美国与知情同意有关的一些问题   总被引:10,自引:1,他引:9  
知情同意是医疗保健和医学研究的一个基本的伦理学要求。这两种情况中,当医学研究的知情同意标准比医疗保健要求更加严格时,知情同意包含了3种要素:(1)告知病人或受试者该研究的性质。包括益处,危险和其他有关内容;(2)确保病人受试者理解所提供的信息;(3)得到病人或受试者自愿的同意,没有能力参与知情同意的病人包括患痴呆和危重病等无决断 能力的病人,这些病人属弱势病人。如要获许对他们的疾病进行研究,我们必须制定保护弱势受试者有效的伦理政策,提出了关于对痴呆病人、危重病人,脑死亡病人研究的伦理学政策。  相似文献

6—12岁儿童脑波超慢功率涨落分布及发展特点   总被引:1,自引:0,他引:1  
对172名6-12岁的正常儿童进行脑波超慢功率涨落特点的研究。结果表明:(1)各组优势涨落平均功率空间分布表现出额低枕高的前后梯度;(2)随着年龄的增加,不同的脑区其发展趋势是不同的,且逆转现象逐渐减少;(3)左右脑表现出左小右大的不对称性;(4)男女生脑波优势涨落功率的空间分布、逆转趋势、方位等有差异。上述结果说明,脑波超慢功率涨落与儿童的成熟过程及功能状态有密切关系。  相似文献

Recent reports of the discovery of a "God module" in the human brain derive from the fact that epileptic seizures in the left temporal lobe are associated with ecstatic feelings sometimes described as an experience of the presence of God. The brain area involved has been described as either (a) the seat of an innate human faculty for experiencing the divine or (b) the seat of religious delusions.
In fact, religious experience is extremely various and involves many parts of the brain, including some that are prehuman in their evolutionary history and some that are characteristically human. In the continuing integration of such experiences, spiritual formation takes place. Thus the entire human brain might be described as a "God module."
Such a process is only possible because of the brain's complexity. The human brain is the most complex entity for its size that we know of. As used here, complexity is a specialized term denoting the presence of a web of interlinked and significant connections—the more intricate the web, the more complex the entity. Complex systems develop only in a milieu that provides both lawfulness and freedom, and they tend to be self-organizing, becoming more complex and more effective as a result of both inward and outward experience. The evidence suggests that both personal growth and spiritual growth are processes of complexification of character, and of the brain itself. This thesis is tested in light of the work of William James and James W. Fowler.  相似文献

Modest advances are being made in understanding the neurology and functions of laughter. The discovery of tickle-induced "laughter" in animals should facilitate the characterization of this basic emotional response of the mammalian brain. The existence of such vocal activities in species other than humans (e.g., rats) suggests that the fundamental brain processes for joyful affect may have emerged early in vertebrate brain evolution. Here, I summarize the little that we know about the evolutionary and brain sources of laughter, and how the accompanying positive emotions may solidify social bonds within the mammalian brain. Discovery of unique neurochemistries that specifically promote laughter and joy may provide clues for development of new classes of antidepressants.  相似文献

Neurobehavioral Changes in Adolescence   总被引:3,自引:0,他引:3  
Adolescents across a variety of species exhibit age-specific behavioral characteristics that may have evolved to help them attain the necessary skills for independence. These adolescent-related characteristics, such as an increase in risk taking, may be promoted less by the hormonal changes of puberty than by developmental events occurring in brain. Among the prominent brain transformations of adolescence are alterations in the prefrontal cortex, limbic brain areas, and their dopamine input, systems that are sensitive to stressors and form part of the neural circuitry modulating the motivational value of drugs and other reinforcing stimuli. Such developmental transformations of the adolescent brain may predispose adolescents to behave in particular ways and make them particularly likely to initiate use of alcohol and other drugs.  相似文献
