The “Jewish Knight” of Slobodka honor culture and the image of the body in an Ultra-Orthodox Jewish context

Scholarship on Ultra-Orthodox Jewish thought has traditionally assumed that the views of these communities derive from a struggle against the Jewish Enlightenment and Zionism, as well as against any values they identify as “modern.” This article challenges that assumption. Beginning with an examination of Ultra-Orthodox sources that present an image of the religious leader as the “ideal Jew,” the author then focuses on sources concerning the founder of the Slobodka Yeshiva in Lithuania. This rabbi intended his students to internalize “modern” norms found in the European honor culture of his time, while translating them into the language of Jewish Ultra-Orthodoxy. The author chooses to present his argument by tracing the image of the body in the Slobodka method, since it is precisely through the nexus of the body that Ultra-Orthodox Judaism was segregated from general European society and culture.     

Unintentional movements induced by sequential transient perturbations in a multi-joint positional task

We explored the phenomenon of unintentional movements of a multi-joint effector produced by multiple transient changes in the external force. The subjects performed a position-holding task against a constant bias force produced by a robot and were instructed not to intervene voluntarily with arm movements produced by changes in the robot force. The robot produced a smooth force increase leading to hand movement from the trunk, followed by a dwell time. Then, the force dropped to its initial value leading to hand movement toward the initial position but with an undershot. Such perturbation episodes were repeated four times in a row. The accumulated perturbation and undershoot distances kept increasing without saturation within the sequence of four perturbation episode. The limb apparent stiffness before dwell time increased over sequential perturbations while apparent stiffness after dwell time decreased. We interpret the results as consequences of a drift of the hand referent coordinate (RC) caused by a hypothesized RC-back-coupling mechanism and a coupled drift of the apparent stiffness. The results show that RC-back-coupling continues to lead to unintentional movements over repeated perturbations and is accompanied by a relatively slow re-setting process.     

How motor practice shapes memory: retrieval but not extra study can cause forgetting

We investigated the retrieval specificity of retrieval-induced forgetting (RIF) of motor sequences. In two experiments, participants learned sequential finger movements, each consisting of the movement of two fingers of either the left or the right hand. In the learning phase, these motor sequences were graphically presented and were to be learned as responses to simultaneously presented letter stimuli. Subsequently, participants selectively practiced half the items of one hand. A final recall test then assessed memory for all initially learned items. We contrasted different kinds of selective practice with each other. Whereas retrieval practice required retrieving motor sequences in response to letter stimuli from the learning phase, extra study was an extension of the learning phase, that is, participants performed motor sequences in response to the same animation graphic display as in the learning phase again accompanied by the letter stimulus. All practice conditions strengthened the practiced items, but only retrieval practice resulted in RIF. Thus, the strengthening of items through practice did not suffice to induce forgetting of related motor sequences. Retrieval was a necessary component for practice to shape memory for body movements by impairing the subsequent recall of motor sequences that were related to the practiced motor sequences.     

汉语成语谜语问题解决中思路竞争的眼动研究

在谜语问题解决过程中, 可能存在着通过简单联想和新异联想寻找答案这两种思路。两个实验中设置了包括寻常答案与新颖答案在内的若干备择答案(实验1为4个, 实验2为6个)供被试选择, 利用眼动技术记录被试在解题过程中的不同时间段内对新颖答案与寻常答案的平均注视时间, 考察汉语成语谜语问题解决中两种思路之间冲突的过程。实验1操纵了任务要求, 实验2操纵了规则线索的有效性。实验结果表明：(1)在成语谜语问题解决中的一段时间内新异联想和简单联想能够同时发生且形成竞争; (2)选择“新颖且合适答案”的任务要求, 提高了成功形成新颖语义联结的概率, 但是并没有加快新异联想发生、发展的进程, 也没有改变两种思路相互竞争的局面; (3)有效的规则线索可以抑制简单联想, 阻止其发生, 同时可以加快新异联想发生、发展的进程。     

合理性对汉语阅读中双字词语义预视效益的优势作用：眼动研究

语义预视效益(SPB)对于揭示阅读中读者能否从副中央凹提取高水平信息具有重要意义。关于SPB的产生机制仍然存在争议。本研究通过同时操控预视词的合理性和语义相关性考察了二者对汉语阅读中双字词SPB的影响。结果发现,合理性主效应显著,合理预视下目标词的注视时间显著短于不合理预视;语义相关性主效应不显著,未发现二者的交互作用。研究结果支持了语境匹配假说,进一步说明了汉语阅读中预视词的合理性对SPB的优势作用。     

英语专业大学生阅读汉语和英语材料的眼动研究

用EyelinkⅡ眼动仪记录23名母语为汉语的英语专业大学生阅读汉语和英语对照材料的眼动情况。结果发现：（1）被试阅读汉—英对照材料时,理解率没有差异,但汉语材料的阅读速度、阅读时间和阅读效率等明显优于英语材料的;（2）在注视次数、平均注视时间、注视频率、平均眼跳幅度和回视入次数等指标上,被试阅读汉语材料的成绩明显高于英语材料的;（3）对汉—英同义目标词加工的眼动特点分析发现,相对于英语目标词,被试对相同像素汉语目标词的加工更难。     

Disequilibrium in the mind,disharmony in the body

Although it is generally acknowledged that experiences of frustration, confusion, and anxiety are embodied phenomena, very little is known about how these processes modulate presumably unconscious, but constantly present, subtle bodily movement. We addressed this problem by tracking the low-level dynamics of body movement, using 1/f noise, pink noise, or “fractal scaling”, during naturalistic experiences of affect in two studies involving deep learning and effortful problem-solving. Our results indicate that body movement fluctuations of individuals experiencing cognitive equilibrium was characteristic of correlated pink noise, but there was a whitening of the signal when participants experienced states that are diagnostic of cognitive distress such as anxiety, confusion, and frustration. We orient our findings within theories that emphasise the embodied nature of cognition and affect and with perspectives that view affective and cognitive processes as emergent products of a self-organising dynamical system (the brain) that is inextricably coupled to the body.     

The Role of Executive Control of Attention and Selective Encoding for Preschoolers' Learning

Selectivity in encoding, aspects of attentional control and their contribution to learning performance were explored in a sample of preschoolers. While the children are performing a learning task, their encoding of relevant and attention towards irrelevant information was recorded through an eye‐tracking device. Recognition of target items was used as measure of learning outcome, and individual differences in resistance to interference and inhibition of attention to task‐irrelevant stimuli (i.e. distractibility) were used as measures of executive control of attention. Results indicated well‐developed selectivity during encoding in young children. Recognition performance was related to selective encoding and aspects of attentional control, explaining individual differences in learning. Copyright © 2011 John Wiley & Sons, Ltd.     

Mediating factors in chick social pecking: II. effects of exposure to movement

Unfamiliarity with movement may lead isolated chicks to respond aggressively when tested with live, moving conspecifics. This hypothesis was tested by comparing the number and locus of pecks by isolated chicks to a stationary or moving model of a chick, and to a live chick. In a second test of the hypothesis chicks that viewed a moving object during isolation and chicks isolated without movement were tested with a live con-specific and their number and locus of pecks were compared. Neither experiment supported the hypothesis. Movement alone failed to excite aggressive pecks and prior experience with movement failed to suppress aggressive pecks. In the first experiment imlated chicks treated the live testmate more aggressively than the moving or stationary model. In the second experiment aggressive pecking of chicks was unaffected by prior experience with movement, These fmdmgs do not support the hypothesis that movement excites aggression in isolated chicks. Nonetheless the results focus attention on the generally neglected problem of emotional and motivational states produced by isolation.
