Gender sceptics and feminist politics

Some feminist gender sceptics hold that the conditions for satisfying the concept woman cannot be discerned. This has been taken to suggest that (i) the efforts to fix feminism’s scope are undermined because of confusion about the extension of the term ‘woman’, and (ii) this confusion suggests that feminism cannot be organised around women because it is unclear who satisfies woman. Further, this supposedly threatens the effectiveness of feminist politics: feminist goals are said to become unachievable, if feminist politics lacks a clear subject matter. In this paper, I argue that such serious consequences do not follow from the gender sceptic position. I presented an earlier version of this paper at the ‘Stirling Political Philosophy Group’ meeting and am grateful to those present for their constructive criticisms. I am also grateful to Alan Millar, the anonymous referees for this journal and Jenny Saul (who has read more than one version of this paper!) for their detailed and extremely helpful comments and suggestions.     

Naming and categorization in young children: v. manual sign training

Following pre-training with everyday objects, 8 children aged from 2 to 4 years learned to produce one manual sign (fists placed one above the other, in front of body) to one stimulus and an alternative manual sign (shoulders touched with ipsilateral hands) to the other stimulus, with each of three pairs of different arbitrary wooden shapes (Set 1). The six stimuli then were presented in category match-to-sample tests, which all subjects passed. Three of the children were next trained to produce the manual signs (denoted as fist/shoulder) for an additional six arbitrary stimuli, Set 2. All 3 children went on to pass category match-to-sample tests for Set 2, and for Set 1 and Set 2 combined. In the final experimental phase, 2 of the children were trained, for one of the six stimulus pairs, to produce the vocal tact "zag" to one stimulus and "vek" to the other. Both children showed category transfer of these vocalizations in test trials with each of the remaining five stimulus pairs, and all the stimuli combined in a 12-stimulus array. In line with Horne and Lowe's (1996) naming account, manual sign naming was found to be as effective as vocal naming in establishing arbitrary stimulus categorization, measured in terms of category sorting and transfer of function. The findings also have implications for the training of verbal repertoires in people with learning disabilities.     

关系复杂性和分类方式对个人关系类别间接性学习的影响

以144名大学生为被试,使用关系复杂性变化的三种虚拟外星生物实验材料,创设功能预测任务和自由分类、限定分类任务,探查关系复杂性和分类方式对个人关系类别间接性学习的影响.结果发现：（1）随着关系复杂性的增高,各学习阶段下,三种学习材料功能预测成绩彼此间均无显著差异;（2）关系复杂性和分类方式对个人关系类别间接性学习的分类结果存在交互影响作用,具体表现为,关系复杂性较低时自由分类和限定分类结果的杰卡德相似性无显著差异,关系复杂性较高和高时限定分类极其显著高于自由分类,自由分类方式下,关系复杂性不同的三种学习材料间差异不显著,限定分类方式下,关系复杂性较高和高两种学习材料分类结果的杰卡德相似性间无显著差异,但均极其显著高于关系复杂性较低的学习材料.     

Word Learning and Attention Allocation Based on Word Class and Category Knowledge

Attention allocation in word learning may vary developmentally based on the novelty of the object. It has been suggested that children differentially learn verbs based on the novelty of the agent, but adults do not because they automatically infer the object's category and thus treat it like a familiar object. The current research examined whether adults and children differentially learn words or attend to objects without access to category knowledge in a relatively difficult (Experiment 1, adult n = 54, child n = 66) and a relatively easy task (Experiment 2, adult n = 88, child n = 62). Results show that category knowledge affects noun and verb extension for children but not adults and that adults similarly attended to objects when learning a verb regardless of category knowledge. These findings highlight the importance of investigating how word class, attention allocation, and categorical inference interact across development. Copyright © 2014 John Wiley & Sons, Ltd.     

人格智力:一种被“冷落”的“热智力”

人格智力(PI)是指个体在对人格及其相关信息推理的基础上,利用这些信息提高一个人的思想、计划和生活经验的能力,包括识别人格信息、形成人格模型、引导个人选择以及系统化计划和目标等相关领域。作为一种新兴的“热智力”,PI并没有像当年情绪智力(EI)那样受人关注。文章从PI的范畴、领域及其局限性等角度分析了这一新能力遭遇“冷落”的原因,指出了PI在整合以人为中心的智力过程中存在概念宽泛、界限模糊、测量的科学性及其形成与发展等诸多值得反思的问题。     

Dimensionality of psychosocial responses to marital disruption

The purpose of the study was to assess whether psychosocial responses to marital disruption were best arranged along one single dimension ranging from maximum positive to maximum negative responses, or whether positive and negative responses constituted two separate and distinct dimensions. Participants were 658 recently divorced individuals. A confirmatory factor analysis revealed that a two-factor model provided a better fit to the data than a one-factor model. Moreover, a number of external variables differentiated between positive and negative responses, indicating that such responses reflect two separate domains. Thus, the findings support the notion that psychosocial responses after marital disruption comprise a bidimensional rather than a unidimensional pattern. The findings are discussed within the general framework of positive-negative asymmetry and the idea that positive and negative evaluations belong to different psychological system.     

Test of a potential link between analytic and nonanalytic category learning and automatic, effortful processing

The link between automatic and effortful processing and nonanalytic and analytic category learning was evaluated in a sample of 29 college undergraduates using declarative memory, semantic category search, and pseudoword categorization tasks. Automatic and effortful processing measures were hypothesized to be associated with nonanalytic and analytic categorization, respectively. Results suggested that contrary to prediction strong criterion-attribute (analytic) responding on the pseudoword categorization task was associated with strong automatic, implicit memory encoding of frequency-of-occurrence information. Data are discussed in terms of the possibility that criterion-attribute category knowledge, once established, may be expressed with few attentional resources. The data indicate that attention resource requirements, even for the same stimuli and task, vary depending on the category rule system utilized. Also, the automaticity emerging from familiarity with analytic category exemplars is very different from the automaticity arising from extensive practice on a semantic category search task. The data do not support any simple mapping of analytic and nonanalytic forms of category learning onto the automatic and effortful processing dichotomy and challenge simple models of brain asymmetries for such procedures.     

Children learn words easier when they are interested in the category to which the word belongs

The overall pattern of vocabulary development is relatively similar across children learning different languages. However, there are considerable differences in the words known to individual children. Historically, this variability has been explained in terms of differences in the input. Here, we examine the alternate possibility that children's individual interest in specific natural categories shapes the words they are likely to learn – a child who is more interested in animals will learn a new animal name easier relative to a new vehicle name. Two‐year‐old German‐learning children (N = 39) were exposed to four novel word–object associations for objects from four different categories. Prior to the word learning task, we measured their interest in the categories that the objects belonged to. Our measure was pupillary change following exposure to familiar objects from these four categories, with increased pupillary change interpreted as increased interest in that category. Children showed more robust learning of word–object associations from categories they were more interested in relative to categories they were less interested in. We further found that interest in the novel objects themselves influenced learning, with distinct influences of both category interest and object interest on learning. These results suggest that children's interest in different natural categories shapes their word learning. This provides evidence for the strikingly intuitive possibility that a child who is more interested in animals will learn novel animal names easier than a child who is more interested in vehicles.     

Is the Lateralized Categorical Perception of Color a Situational Effect of Language on Color Perception?

This study investigated whether and how a person's varied series of lexical categories corresponding to different discriminatory characteristics of the same colors affect his or her perception of colors. In three experiments, Chinese participants were primed to categorize four graduated colors—specifically dark green, light green, light blue, and dark blue—into green and blue; light color and dark color; and dark green, light green, light blue, and dark blue. The participants were then required to complete a visual search task. Reaction times in the visual search task indicated that different lateralized categorical perceptions (CPs) of color corresponded to the various priming situations. These results suggest that all of the lexical categories corresponding to different discriminatory characteristics of the same colors can influence people's perceptions of colors and that color perceptions can be influenced differently by distinct types of lexical categories depending on the context.     

The Body-Machine Interface: A New Perspective on an Old Theme

ABSTRACT

Body-machine interfaces establish a way to interact with a variety of devices, allowing their users to extend the limits of their performance. Recent advances in this field, ranging from computer interfaces to bionic limbs, have had important consequences for people with movement disorders. The authors provide an overview of the basic concepts underlying the body-machine interface with special emphasis on their use for rehabilitation and for operating assistive devices. They outline the steps involved in building such an interface and highlight the critical role of body-machine interfaces in addressing theoretical issues in motor control as well as their utility in movement rehabilitation.
