All Giraffes Have Female‐Specific Properties: Influence of Grammatical Gender on Deductive Reasoning About Sex‐Specific Properties in German Speakers

Grammatical gender is independent of biological sex for the majority of animal names (e.g., any giraffe, be it male or female, is grammatically treated as feminine). However, there is apparent semantic motivation for grammatical gender classes, especially in mapping human terms to gender. This research investigated whether this motivation affects deductive inference in native German speakers. We compared German with Japanese speakers (a language without grammatical gender) when making inferences about sex‐specific biological properties. We found that German speakers tended to erroneously draw inferences when the sex in the premise and grammatical gender of the target animal agreed. An over‐generalization of the grammar–semantics mapping was found even when the sex of the target was explicitly indicated. However, these effects occurred only when gender‐marking articles accompanied the nouns. These results suggest that German speakers project sex‐specific biological properties onto gender‐marking articles but not onto conceptual representations of animals per se.     

Searching for Control: Priming Randomness Increases the Evaluation of Ritual Efficacy

Reestablishing feelings of control after experiencing uncertainty has long been considered a fundamental motive for human behavior. We propose that rituals (i.e., socially stipulated, causally opaque practices) provide a means for coping with the aversive feelings associated with randomness due to the perception of a connection between ritual action and a desired outcome. Two experiments were conducted (one in Brazil [n = 40] and another in the United States [n = 94]) to evaluate how the perceived efficacy of rituals is affected by feelings of randomness. In a between‐subjects design, the Scramble Sentence Task was used as a priming procedure in three conditions (i.e., randomness, negativity, and neutral) and participants were then asked to rate the efficacy of rituals used for problem‐solving purposes. The results demonstrate that priming randomness increased participants' perception of ritual efficacy relative to negativity and neutral conditions. Implications for increasing our understanding of the relationship between perceived control and ritualistic behavior are discussed.     

Familiar Verbs Are Not Always Easier Than Novel Verbs: How German Pre‐School Children Comprehend Active and Passive Sentences

Many studies show a developmental advantage for transitive sentences with familiar verbs over those with novel verbs. It might be that once familiar verbs become entrenched in particular constructions, they would be more difficult to understand (than would novel verbs) in non‐prototypical constructions. We provide support for this hypothesis investigating German children using a forced‐choice pointing paradigm with reversed agent‐patient roles. We tested active transitive verbs in study 1. The 2‐year olds were better with familiar than novel verbs, while the 2½‐year olds pointed correctly for both. In study 2, we tested passives: 2½‐year olds were significantly below chance for familiar verbs and at chance for novel verbs, supporting the hypothesis that the entrenchment of the familiar verbs in the active transitive voice was interfering with interpreting them in the passive voice construction. The 3½‐year olds were also at chance for novel verbs but above chance with familiar verbs. We interpret this as reflecting a lessening of the verb‐in‐construction entrenchment as the child develops knowledge that particular verbs can occur in a range of constructions. The 4½‐year olds were above chance for both familiar and novel verbs. We discuss our findings in terms of the relative entrenchment of lexical and syntactic information and to interference between them.     

Dissociation between magnitude comparison and relation identification across different formats for rational numbers

ABSTRACT

The present study examined whether a dissociation among formats for rational numbers (fractions, decimals, and percentages) can be obtained in tasks that require comparing a number to a non-symbolic quantity (discrete or else continuous). In Experiment 1, college students saw a discrete or else continuous image followed by a rational number, and had to decide which was numerically larger. In Experiment 2, participants saw the same displays but had to make a judgment about the type of ratio represented by the number. The magnitude task was performed more quickly using decimals (for both quantity types), whereas the relation task was performed more accurately with fractions (but only when the image showed discrete entities). The pattern observed for percentages was very similar to that for decimals. A dissociation between magnitude comparison and relational processing with rational numbers can be obtained when a symbolic number must be compared to a non-symbolic display.     

The Phenomenology of Early Psychosis Elicited in an Occupational Therapy Expressive Evaluation

Expressive assessments facilitate sharing, and the therapeutic understanding of youth. The experiences of nine young adults seeking help for psychosis were explored with an arts-based, occupational therapy expressive evaluation. The study used participant-observation methods. Data analysis drew on hermeneutic phenomenology. The findings illustrate the challenges these participants have in feeling connected to a shared world of doing, and in locating themselves within the temporal flow of time. Of significance was the potential to read the unfolding of creation in clay media as an acted narrative to tap into “constellations of meaning.” Implications for clinical practice and professional reasoning are highlighted.     

Tool use in neurodegenerative diseases: Planning or technical reasoning?

Recent works showed that tool use can be impaired in stroke patients because of either planning or technical reasoning deficits, but these two hypotheses have not yet been compared in the field of neurodegenerative diseases. The aim of this study was to address the relationships between real tool use, mechanical problem‐solving, and planning skills in patients with Alzheimer's disease (AD, n = 32), semantic dementia (SD, n = 16), and corticobasal syndrome (CBS, n = 9). Patients were asked to select and use ten common tools, to solve three mechanical problems, and to complete the Tower of London test. Motor function and episodic memory were controlled using the Purdue Pegboard Test and the BEC96 questionnaire, respectively. A data‐transformation method was applied to avoid ceiling effects, and single‐case analysis was performed based on raw scores and completion time. All groups demonstrated either impaired or slowed tool use. Planning deficits were found only in the AD group. Mechanical problem‐solving deficits were observed only in the AD and CBS groups. Performance in the Tower of London test was the best predictor of tool use skills in the AD group, suggesting these patients had general rather than mechanical problem‐solving deficits. Episodic memory seemed to play little role in performance. Motor dysfunction tended to be associated with tool use skills in CBS patients, while tool use disorders are interpreted as a consequence of the semantic loss in SD in line with previous works. These findings may encourage caregivers to set up disease‐centred interventions.     

正念与大学生智慧推理的关系：个人成长主动性的部分中介作用

为了考察正念、个人成长主动性(PGI)与智慧推理之间的关系,采用五因素正念量表、个人成长主动性量表与智慧推理量表对242名18-27岁成年早期的大学生进行调查,探讨正念对智慧推理的影响,并检验个人成长主动性的中介效应模型。结果发现：（1）正念对智慧推理水平具有显著的正向影响;（2）个人成长主动性在正念对智慧推理的影响中发挥部分中介作用。     

推理方向与规则维度对儿童因果推理的影响

采用Frye和Zelazo等（1996）所设计的“二进二出”装置（斜面滚球装置）,设置了不同的推理方向、规则维度的因果推理任务,采用个别实验法,研究了60名3.5～4.5岁儿童因果推理能力的发展。结果发现：（1）儿童在不同方向的因果推理任务上成绩差异显著,因→果推理成绩要好于果→因推理;（2）不同维度下儿童的推理成绩有极显著的差异性,一维的因果推理更容易,三维合取规则的因果推理任务更难;（3）3.5～4岁左右是儿童因果推理能力发展的快速期。
