Faire parler l’expérience étudiante en orientation pour soutenir la capabilité à s’orienter

The report built by the students to their vocational path has been little studied, whereas it is currently the subject of much political and societal attention. Based on the concepts of capabilities, student experience and life events, the study, conducted by questionnaire, mainly sought to better understand the guidance path lived, of 110 students enrolled in the second year of a degree in psychology in France (objective 1). Mobilizing, in order to compare (objective 2), two methods of textual analysis carried out in double blind, one automatic, other manual, the results show that the enunciation of the events having marked their trajectory and their current questioning in orientation testify of a reflexive activity in link with their capabilities. By mentioning rich past experiences, painful episodes of life, various influences and frequent readjustments, the events mentioned show a certain distance to oneself and a propensity to think about the future in relation to the past. Marked by speeches of uncertainty and fear concerning the capability and identity aspects, the academic choices to be made and the future vocational integration to be carried out, the student questions are mainly part of a short temporality. Capacitive devices in vocational guidance are discussed and extensions of analysis and research outlined.     

睾酮与人类攻击行为

睾酮是一种可以在男性的睾丸间质细胞、女性卵巢和胎盘的皮层细胞中合成并分泌的雄性激素, 它可以调节个体的各种生理、形态和行为过程, 对个体生存和繁殖至关重要。大量研究表明, 睾酮与社会行为的关联存在双向性, 睾酮可以调节社会行为, 社会行为可以反馈并进一步影响睾酮水平。我们将关注点聚焦于睾酮与人类攻击行为之间的关联。早期研究发现, 高睾酮水平个体表现出更高的攻击性; 近期的研究根据挑战假设理论模型和生物社会地位模型得出, 人体内的睾酮水平对竞争性相互作用具有高度反应性。此外, 通过对大量研究的回顾与分析, 我们总结出睾酮水平的变化可以通过增强杏仁核的反应性或减少前额叶皮质-杏仁核功能耦合来影响攻击行为。未来的研究者应考虑其他激素(如皮质醇)和人格特征调节睾酮和人类攻击行为之间关系的潜在作用, 以及相关的生物学机制。     

等效性检验——结构方程模型评价和测量不变性分析的新视角

常用的结构方程模型拟合指数存在一定局限, 如χ ²以传统零假设为目标假设, 无法验证模型, 而RMSEA和CFI等描述性的拟合指数不具备推断统计性质, 等效性检验有效弥补了这些问题。首先说明等效性检验如何评价单个模型的拟合, 并解释其与零假设检验的不同, 然后介绍等效性检验如何分析测量不变性, 接着用实证数据展示了等效性检验在单个模型评价和测量不变性检验中的效果, 并与传统模型评价方法比较。     

Explaining neurocognitive aging: is one factor enough?

As an introduction to the special issue on neurocognitive factors underlying age effects, we discuss a number of recent developments in the literature on aging. The classic distinction between generalized and process-specific cognitive changes with old age has reappeared in the distinctions between the frontal lobe hypothesis and more differentiated views of neurocognitive aging. We argue that neurological decay in the frontal cortex has important implications for cognitive control, but that the frontal lobe hypothesis does not capture the plethora of changes that characterize aging and incorrectly suggests a unitary effect.     

Supervenience and Basic Christian Beliefs

A field-oriented interpretation of Whiteheadian societies of actual occasions, when used to explain the notion of "strong supervenience" as applied to the mind-brain problem, allows one to claim that not only higher-level properties such as consciousness but even higher-level entities such as the mind or soul are emergent from lower-level systems of neuronal interaction. Moreover, it also explains the preexistence of God to the world and Christian belief in eternal life with the triune God in a way that is impossible within the limits of a theory of strong supervenience.     

Mathematical determinacy and the transferability of aboutness

Competent speakers of natural languages can borrow reference from one another. You can arrange for your utterances of ‘Kirksville’ to refer to the same thing as my utterances of ‘Kirksville’. We can then talk about the same thing when we discuss Kirksville. In cases like this, you borrow “aboutness” from me by borrowing reference. Now suppose I wish to initiate a line of reasoning applicable to any prime number. I might signal my intention by saying, “Let p be any prime.” In this context, I will be using the term ‘p’ to reason about the primes. Although ‘p’ helps me secure the aboutness of my discourse, it may seem wrong to say that ‘p’ refers to anything. Be that as it may, this paper explores what mathematical discourse would be like if mathematicians were able to borrow freely from one another not just the reference of terms that clearly refer, but, more generally, the sort of aboutness present in a line of reasoning leading up to a universal generalization. The paper also gives reasons for believing that aboutness of this sort really is freely transferable. A key implication will be that the concept “set of natural numbers” suffers from no mathematically significant indeterminacy that can be coherently discussed.     

Extending the spectrum idea: child personality,parenting and psychopathology

The spectrum hypothesis, postulating that differences between referred and non‐referred samples are confined to mean level differences, is elaborated by exploring whether the covariation between child problem behaviour and its predictors—child personality and parenting, rated by mothers—is similar in referred (N = 205) and non‐referred (N = 596) children and whether personality by parenting interactions can be generalized across samples. Results showed significant mean level differences for all the variables. Both personality and parenting explained problem behaviour, with some differences in strength of the effects across samples. Parenting by personality interactions mainly predicted externalizing behaviour, with benevolence and conscientiousness as the most prominent moderators. Results confirmed that moderators of problem behaviour operate similarly in the two samples, thus corroborating the spectrum hypothesis. Copyright © 2006 John Wiley & Sons, Ltd.

认知年老化与执行衰退假说

在认知年老化领域,执行衰退假说是近年来新兴的一种理论。执行衰退假说在理论上具有很强的吸引力,但在实证研究中却存在很多困难,如执行功能的可分离性问题,执行功能测量的信度和效度问题,以及执行功能与加工速度的关系问题。目前,该领域研究的焦点是：在行为学水平上,控制一般性因素（加工速度）后,执行功能是否仍对认知年老化起重要的中介作用;在神经水平上,执行（额叶）功能随龄的变化情况,以及在认知年老化过程中,额叶在大脑功能重组中扮演的角色。最终实现对认知年老化的理解,需要将认知功能与大脑结构联系起来;既看到广泛存在的共同的基本机制,又不能忽略不同认知结构的选择性变化。
