Numbsense of shape,texture, and objects after left parietal infarction: A case report

Numbsense is a phenomenon, wherein patients can correctly respond to somatosensory stimuli at a higher rate than expected by chance, but cannot perceive the same stimuli consciously. Previously, numbsense has been reported in tactile localization of stimuli on the patient’s own body. Here, we describe a patient with numbsense that involved touched objects. The patient could not recognize the majority of somatosensory stimuli after left parietal infarction, but could correctly select shape, texture, and object stimuli more frequently than expected by chance.     

What is Locke's Theory of Representation?

On a currently popular reading of Locke, an idea represents its cause, or what God intended to be its cause. Against Martha Bolton and my former self (among others), I argue that Locke cannot hold such a view, since it sins against his epistemology and theory of abstraction. I argue that Locke is committed to a resemblance theory of representation, with the result that ideas of secondary qualities are not representations.     

Conceptualising ‘Authority’

Abstract

This paper attempts a conceptualisation of authority intended to be useful across all areas where the concept is relevant. It begins by setting off authority against power, on the one hand, and respect, on the other, and then spells out S₁’s authority as consisting in S₂’s voluntary action performed in the belief that S₁ would approve of it. While this definition should hold for authority generally, a distinction is made between three different kinds of authority according to what grounds them: personal, acquired and bestowed authority. Authority thus defined is then used as an example to argue that there is a kind of property that is response-dependent (R-D), but, consisting in all and only a response, is ontologically different from both secondary qualities and value judgments. While secondary qualities are interactive in that they depend on both the object and the perceiver and on what they are like, genuinely R-D qualities depend ontologically and metaphysically only on the responder. And while value judgments require a concept, R-D qualities require an action as a response. It is hoped that this metaphysical underpinning might be helpful in the discussion of authority in other areas of philosophy and beyond.     

Motivation-focused thinking: Buffering against stress-related physical symptoms and depressive symptomology

Developmental transitions are experienced throughout the life course and necessitate adapting to consequential and unpredictable changes that can undermine health. Our six-month study (n = 239) explored whether selective secondary control striving (motivation-focused thinking) protects against the elevated levels of stress and depressive symptoms increasingly common to young adults navigating the challenging school-to-university transition. Path analyses supplemented with tests of moderated mediation revealed that, for young adults who face challenging obstacles to goal attainment, selective secondary control indirectly reduced long-term stress-related physical and depressive symptoms through selective primary control and previously unexamined measures of discrete emotions. Results advance the existing literature by demonstrating that (a) selective secondary control has health benefits for vulnerable young adults and (b) these benefits are largely a consequence of the process variables proposed in Heckhausen et al.’s (2010) theory.

中小学生数学知识观的调查研究

本研究采用12道假设性情境题目和包含数学涉及运算、思考、实用性三个维度的数学认识问卷,选取90名六年级小学生和106名初二学生作为被试,探讨中小学生的数学知识观。结果表明:1)中小学生数学知识观形成及发展与学校数学课程内容紧密相关。2)中小学生数学知识观存在差异,主要表现在初二学生对假设性情境的认同程度显著地高于六年级学生;在数学认识问卷的数学实用性维度上,六年级学生的肯定程度显著地高于初二学生。3)从总体上看,学生的学业水平与数学知识观的关系不大。     

Agonistic behaviour and bite wound patterns in wild water voles (Arvicola terrestris L.)

Intra‐specific aggression was investigated in a wild colony of Water voles between 1999 and 2004 in South Wales, UK. The occurrence and location (i.e. on the head, neck, body or tail) of bite wounds were recorded for adult and juvenile male and female voles. The greatest (33%) incidence of bite wounds were recorded on juvenile females and the lowest (18%) in adult females. Seasonal analysis of wound data in adults revealed that females were more likely to be bitten during the breeding season whereas bite patterns in males did not vary seasonally. Analysis of bite pattern topography revealed that most Water voles seemingly attempt to bite vulnerable target areas of the body (namely the head and tail). This is in contrast with studies on rats and mice where competitive forms of attack (particularly involving males) largely avoid these areas of the attacked animal's body. Targeting vulnerable areas is normally a characteristic of defensive modes of attack. Patterns of bite topography and agonistic behaviour in this species seem to reflect competitive interactions between individuals, particularly between territorial females and their female offspring, over access to essential resources.

控制理论:诠释毕生发展的新视点

控制发展理论的基本概念包括初级控制与次级控制。初级控制指的是指向外部环境的行为和改变环境以适应个体需求的企图：次级控制的目标是指向个体自身,目的是将初级控制的丧失最小化、维持并提高当前的初级控制水平。次级控制一方面帮助个体应对初级控制的失败,另一方面通过选择功能提高初级控制水平。与次级控制相比,初级控制对个体发展的适应性机是居首位的。该详细阐述了两种控制的含义、维度模式及其相互作用,并从毕生发展的角度讨论了控制的发展特点。     

Distributing mathematical practice of third and seventh graders: Applicability of the spacing effect in the classroom

We examined the effect of distributed practice on the mathematical performance of third and seventh graders (N = 213) in school. Students first received an introduction to a mathematical topic, derived from their curriculum. Thereafter, they practiced in one of two conditions. In the massed condition, they worked on three practice sets in 1 day. In the distributed condition, they worked on one practice set per day for 3 consecutive days. Bayesian analyses of the performance in two follow‐up tests 1 and 6 weeks after the last practice set revealed a positive effect of distributed practice as compared with massed practice in Grade 7. In Grade 3, a positive effect of distributed practice was supported by the data only in the test 1 week after the last practice set. The results suggest that distributed practice is a powerful learning tool for both elementary and secondary school students in the classroom.     

Anxiety, Attributional Thinking, and the Primary Process

In earlier publications, experimental evidence was provided for the existence of the primary vs. secondary process mental organization posited by Freud. A well-established cognitive categorization test based on attributional and relational similarity was found to map on to primary and secondary principles of mental organization respectively, thus offering the opportunity to test hypotheses drawn from psychoanalytic theory independent of the clinical situation. In prior work, primary process shifts occurred under three different conditions-all predicted by psychoanalytic theory: (1) when stimuli were (subliminal) unconscious; (2) when participants were 3-5 years of age; and (3) when tasks were implicit. In the current study, a fourth condition is examined dealing with the relationship of conscious anxiety to primary and secondary processes. In a naturalistic study, 120 patients waiting in medical center waiting rooms rated how anxious they felt on a 10-point scale and then completed a version of the categorization test alluded to above. Those who reported any anxiety at all showed a signifi cant shift toward primary process categorization over those participants who rated themselves as calm. The implications of this fourth fi nding are discussed with respect to signal anxiety and symptom formation.
