Comparative analyses of rider position according to skill levels during walk and trot in Jeju horse

The purpose of this study was to evaluate the rider position at walk and trot as a function of rider skill level by analyzing joint angles. Participants included three advanced riders and six beginners, and training was conducted for one hour, twice a week for 24 weeks. In the walk stage of the beginners’ group, the elbows and shoulders sustained postures comparable to those of the advanced riders group; the trunk tilted forwards at first, but later it tilted slightly behind the vertical. The knee, ankle, and left–right angle kept stable postures after 12 weeks of training (p < .05). The front-rear (FR) angle of the beginners group improved during training, but it was still lower than the advanced riders group after 24 weeks of training (p < .05). At trot, while the knee angle measurement of the beginners’ group was similar to the advanced riders, the ankle joint sustained a forward point posture. The ankle joint maintained dorsiflexion posture with 83.9° ± 5.3 in the advanced riders group, while the beginners group had plantar flexion posture with 98.7° ± 6.0. This study suggested that the correlation between the joint and body segment angles could be an important indicator in the evaluation of rider proficiency.     

“Where is the sun” for hemi-neglect patients?

Human observers use prior constraints to disambiguate a scene; in particular, light is preferentially seen as coming from above but also slightly from the left. One explanation of this lateral bias could be a cerebral hemispheric difference. The aim of the present study was to determine the preferred light source position for neglect patients. For this purpose, we used the ambiguous shaded “Polo Mint” stimulus, a ring divided into eight equal sectors. All sectors but one were the same shape, convex or concave, as determined by the light source position. Participants had to report the side (left or right) of the odd sector or, in a separate experiment, to report its shape (convex or concave). Eight patients with spatial neglect (left neglect N = 7, right neglect N = 1) after a right or left temporo-parietal or thalamic lesion and 14 control participants ran the experiment. Left neglect patients showed a significantly different light bias from the bias observed for controls and for the right neglect patient (i.e., a reduction of the left bias or a right bias rather than a left bias). We conclude that some disabilities presented by patients with spatial neglect may be due to difficulties processing information that is not present in the visual field or imagined in the representational scene.     

On the time-course of adjacent and non-adjacent transposed-letter priming

We compared effects of adjacent (e.g. atricle-ARTICLE) and non-adjacent (e.g. actirle-ARTICLE) transposed-letter (TL) primes in an event-related potential (ERP) study using the sandwich priming technique. TL priming was measured relative to the standard double-substitution condition. We found significantly stronger priming effects for adjacent transpositions than non-adjacent transpositions (with two intervening letters) in behavioural responses (lexical decision latencies), and the adjacent priming effects emerged earlier in the ERP signal, at around 200-ms post-target onset. Non-adjacent priming effects emerged about 50 ms later and were short-lived, being significant only in the 250- to 300-ms time-window. Adjacent transpositions on the other hand continued to produce priming in the N400 time-window (300- to 500-ms post-target onset). This qualitatively different pattern of priming effects for adjacent and non-adjacent transpositions is discussed in the light of different accounts of letter transposition effects and the utility of drawing a distinction between positional flexibility and positional noise.     

即刻学习判断的系列位置效应：内外部线索的影响

为了检验即刻学习判断对内外部线索的敏感性,实验一被试为22名高中生,材料为三列含15个词语的清单,先逐个呈现词语系列位置信息,被试在学习前进行即刻学习判断,结果发现学习判断有显著首因效应,表明学习判断对系列位置信息这一外部线索比较敏感。实验二被试为20名高中生,先逐个呈现词语系列位置信息,被试在学习后进行即刻学习判断,结果发现学习判断同样有显著首因效应,表明学习判断对内部线索的敏感性并未强于外部线索。     

创造性倾向对科学问题解决中原型位置效应的影响*

以科学发明创造题目为实验材料,采用“一对一”的实验范式,对创造性问题解决中的创造性倾向与原型位置效应的关系进行了探讨,实验考察了不同创造性倾向个体在创造性问题解决中的原型位置效应,创造性倾向包括想象力、冒险性、好奇性、挑战性四个因素,结果发现:创造性倾向总分、好奇性、挑战性对原型位置效应有影响,而且原型位置效应随着创造性倾向、好奇性、挑战性的降低而显著;想象力、冒险性对原型位置效应的影响不显著。

Gender Studies in Post-Soviet Society: Western Frames and Cultural Differences

This article is devoted to theexploration of some trends in gender studies incontemporary Russia and is based on ourresearch and teaching in the field over thecourse of seven years. The main concepts ofgender research – gender, feminism,women's subjectivity – were introduced to theRussian public early in 1990s; Russian genderstudies began to develop as a whole due to theapplication of Western concepts and theories.The article examines the growth of genderstudies over the last 10 years, contextualdifferences as well as theoretical approachesin Russian gender studies as these have arisenin the context of the `Russia – West'dichotomy.     

The savings problem in the original position: assessing and revising a model

Abstract

The common conception of justice as reciprocity seemingly is inapplicable to relations between non-overlapping generations. This is a challenge also to John Rawls’s theory of justice as fairness. This text responds to this by way of reinterpreting and developing Rawls’s theory. First, by examining the original position as a model, some revisions of it are shown to be wanting. Second, by drawing on the methodology of constructivism, an alternative solution is proposed: an amendment to the primary goods named ‘sustainability of values’. This revised original position lends support to intergenerational justice as fairness.     

Further differentiating item and order information in semantic memory: students’ recall of words from the “CU Fight Song”, Harry Potter book titles,and Scooby Doo theme song

University of Colorado (CU) students were tested for both order and item information in their semantic memory for the “CU Fight Song”. Following an earlier study by Overstreet and Healy [(2011). Item and order information in semantic memory: Students’ retention of the “CU fight song” lyrics. Memory & Cognition, 39, 251–259. doi:10.3758/s13421-010-0018-3], a symmetrical bow-shaped serial position function (with both primacy and recency advantages) was found for reconstructing the order of the nine lines in the song, whereas a function with no primacy advantage was found for recalling a missing word from each line. This difference between order and item information was found even though students filled in missing words without any alternatives provided and missing words came from the beginning, middle, or end of each line. Similar results were found for CU students’ recall of the sequence of Harry Potter book titles and the lyrics of the Scooby Doo theme song. These findings strengthen the claim that the pronounced serial position function in semantic memory occurs largely because of the retention of order, rather than item, information.
