Time and direction preparation of the long latency stretch reflex

This study investigated time and direction preparation of motor response to force load while intending to maintain the finger at the initial neutral position. Force load extending or flexing the index finger was given while healthy humans intended to maintain the index finger at the initial neutral position. Electromyographic activity was recorded from the first dorsal interosseous muscle. A precue with or without advanced information regarding the direction of the forthcoming force load was given 1000 ms before force load. Trials without the precue were inserted between the precued trials. A long latency stretch reflex was elicited by force load regardless of its direction, indicating that the long latency stretch reflex is elicited not only by muscle stretch afferents, but also by direction-insensitive sensations. Time preparation of motor response to either direction of force load enhanced the long latency stretch reflex, indicating that time preparation is not mediated by afferent discharge of muscle stretch. Direction preparation enhanced the long latency stretch reflex and increased corticospinal excitability 0–20 ms after force load when force load was given in the direction stretching the muscle. These enhancements must be induced by preset of the afferent pathway mediating segmental stretch reflex.     

Housing First and Photovoice: Transforming Lives,Communities, and Systems

This article presents findings from a community‐based participatory evaluation of a Housing First program on the Island of O'ahu. In this study, clients in a Housing First program used Photovoice to evaluate the program and to advocate for progressive housing policies. Written together by members of the Housing First Photovoice group, this collaborative article describes the outcomes from both the Housing First program and the Photovoice project and demonstrates the ways in which participatory program evaluations can interact with client‐driven programs like Housing First to produce a cumulative, transformative impact. Findings suggest that community psychologists hoping to re‐engage with community mental health systems through enacting transformative change should consider taking a community‐based participatory approach to program evaluation because increased client voice in community mental health programs and their evaluations can have far‐reaching, transformative impacts for research, practice, and policy.     

精诚合一:医学哲学事业的永恒主题

医学哲学事业的价值在于发现并弘扬医学的基本精神。“精诚合一”是医学亘古不变的基本精神。当代医学哲学研究的任务是揭示医学的“精诚合一”特征及其深刻内涵,注重“精”与“诚”的有机结合,批判现实医疗活动和理论研究在“精”、“诚”问题上的片面,弘扬医学的基本精神。     

发展性计算障碍儿童的数认知

发展性计算障碍作为一种特异性学习障碍,影响儿童的数学成就与数学学习观念,因而引起了多学科研究的关注和重视。文章分析了发展性计算障碍领域在数认知方面的已有研究,揭示了发展性计算障碍的数认知缺陷及内部差异,从一般认知加工障碍与数字加工模块障碍两个角度阐述了发展性计算障碍的可能成因,最后对当前研究进行了小结与展望,认为数认知缺陷的复杂关系、亚类型特征、成因之间的相互作用与机制还需进一步研究     

Spontaneous translation and language mixing in a polyglot aphasic

The literature on language mixing in polyglot aphasics is reviewed and a case report of a patient with spontaneous translation is presented. A microgenetic model of language processing provides an interpretive framework for language mixing and spontaneous translation as symptoms of polyglot aphasia. It is suggested that language mixing reflects a deficit at the linguistic level while spontaneous translation reflects a deficit at the prelinguistic level of language processing. A hypothesis about the organization of multiple languages in a single speaker is proposed.     

THE EXISTENCE OF GOD AND THE CREATION OF THE UNIVERSE

Abstract. Kant argues that any argument for a transcendent God presupposes the logically flawed ontological argument. The teleological argument cannot satisfy the demands of reason for a complete explanation of the meaning and purpose of our universe without support from the cosmological argument. I avoid the assumption of a perfect being, and hence the ontological argument, in my version of the cosmological argument. The necessary being can be identified with the creator of the universe by adding analogical mental relations. The creation of the universe is then shown to reflect modern scientific cosmology as well as stories and metaphors in the Eastern and Western religious traditions and to resolve the problem of evil.     

幽明之故与天人之际--从船山易学的视域看

易学具有一个言幽明而不言有无的视域,明清之际的思想家王夫之的研究表明,从这个视域可以更为深入地理解中国哲学的基本问题:天人之际.天人之际的根本回答不在于流俗所理解的"天人合一",而在于天人相继.通过天人相继,确立的是人的自由以及人道的基本依据.而且,在幽明之故的视野中,还可以生发出中国古典思想对原善问题的基本理解,善不是别的,正是在人道的畛域内发生的对天人之间的存在连续性的努力.     

Can Infinitival to Omissions and Provisions Be Primed? An Experimental Investigation Into the Role of Constructional Competition in Infinitival to Omission Errors

An experimental study was conducted on children aged 2;6–3;0 and 3;6–4;0 investigating the priming effect of two WANT‐constructions to establish whether constructional competition contributes to English‐speaking children's infinitival to omission errors (e.g., *I want ___ jump now). In two between‐participant groups, children either just heard or heard and repeated WANT‐to, WANT‐X, and control prime sentences after which to‐infinitival constructions were elicited. We found that both age groups were primed, but in different ways. In the 2;6–3;0 year olds, WANT‐to primes facilitated the provision of to in target utterances relative to the control contexts, but no significant effect was found for WANT‐X primes. In the 3;6–4;0 year olds, both WANT‐to and WANT‐X primes showed a priming effect, namely WANT‐to primes facilitated and WANT‐X primes inhibited provision of to. We argue that these effects reflect developmental differences in the level of proficiency in and preference for the two constructions, and they are broadly consistent with “priming as implicit learning” accounts. The current study shows that (a) children as young as 2;6–3;0 years of age can be primed when they have only heard (not repeated) particular constructions, (b) children are acquiring at least two constructions for the matrix verb WANT, and (c) that these two WANT‐constructions compete for production.     

What Children Feel About Their First Encounter with Child and Adolescent Psychiatry

The first meeting in psychotherapeutic and psychosocial work, has a big impact on the continuation. It is a less explored research field. Children’s “voices” tend to come in the back-ground in family therapy and other settings. In a project at CAP (Child and Adolescent Psychiatry) the children’s views were collected in interviews with parents and therapists present. The grounded theory analysis process was used. The children addressed the importance of the therapist’s actions and positions in helping them to be able to communicate and to be in a dialogue. To be accepted and allowed to express feelings was important, and so was how the therapist managed to adjust to each person in the room and give space for various perspectives.     

Eavesdropping on social life: The accuracy of stranger ratings of daily behavior from thin slices of natural conversations

In two studies the authors examined the accuracy of stranger ratings of daily behavior based on thin slices of natural conversations. Methodologically, the studies extend past research by using a behavioral accuracy criterion, benchmarking zero-acquaintance accuracy against target and informant accuracy, and employing a representative design that sampled contexts from targets’ daily situations. Theoretically, the studies investigate how stereotypes influence the accuracy of first impressions depending on their sample-based validity. Across both studies, after listening to five conversational snippets (2.5 min total), the ratings of strangers were as accurate as the targets’ and informants’ ratings. Further, ratings for gender-stereotypic behaviors with a kernel of truth resulted in greater initial accuracy than ratings for gender-stereotypic behaviors with no kernel of truth.
