Hemispheric asymmetries in the split-fovea model of semantic processing

We report a series of neural network models of semantic processing of single English words in the left and the right hemispheres of the brain. We implement the foveal splitting of the visual field and assess the influence of this splitting on a mapping from orthography to semantic representations in single word reading. The models were trained on English four-letter words, presented according to their frequency in all positions encountered during normal reading. The architecture of the model interacted with the training set to produce processing asymmetries comparable to those found in behavioral studies. First, the cueing effects of dominant and subordinate meanings of ambiguous words were different for words presented to the left or to the right of the input layer. Second, priming effects of groups of related words were stronger in the left input than the right input of the model. These effects were caused by coarser-coding in the right half compared with the left half of the model, an emergent effect of the split model interacting with informational asymmetries in the left and right parts of words in the lexicon of English. Some or all of the behavioral data for reading single words in English may have a similar origin.     

哲学视域中战国楚竹书《周易》的文献价值

上海博物馆所藏楚竹书<周易>见证了数字式爻题的早已存在,与其他传本的<周易>爻题一样,充分蕴示了卦所潜涵的繁复无尽的变动不居之流变情状及卦与卦间所潜涵的同样繁复无尽的流变互通情状,由此而充分符示了宇宙人生中两大类势力互动格局繁复无尽的变动不居之流变图景与诸格局间同样繁复无尽的流变互通图景.楚竹书<周易>的卦爻画已是完全符号化了的卦爻画,但符号化的卦爻画于西周时期<周易>古经成书时当已存在,这种卦爻画乃是易学成为具有自身特有话语系统的高度哲学性的天人之学的根基.残存的楚竹书<周易>卦名后与上爻之辞终了后的奇特符号标识,昭示了卦与物事的极而必反、覆而相通之理,但尚难解读出经文分篇方面的信息.     

论伦理秩序

实存的伦理关系是客观条件与主观条件的历史性统一,伦理关系本质上是现实合理性秩序中的关系,是有主体精神渗透其中并通过道德、法律、习俗等规则体系维系的关系,它的首要问题是秩序的合理性和正当性。研究伦理秩序应把道德和伦理两个概念加以区分;伦理秩序的顺畅和谐在于道德的有效调节,也在于法律的有效控制。伦理秩序在社会变革中经过必然与自由的辩证运动,使矛盾化解,推动社会和谐发展。和谐社会应当是以公正支撑的合理的伦理秩序的社会。     

Episodic Memory in Adult Age and Effects of Sibship Size and Birth Order: Longitudinal Data

This study examined the effects of sibship size and birth order on episodic memory performance in adulthood and old age. Participants were 1,141 healthy individuals aged 35–80 years, who took part in a longitudinal project on age, health, and memory. Episodic memory measurements over a 5-year interval included tests of recognition (recognition of faces, family names, first names, and nouns) and tests of recall (free recall of sentences, free recall and cued recall of nouns, and recall of activities). Results showed significant effects for both recall and recognition, that is, the smaller the sibship size is for an individual and the earlier born, the better memory performance. These results demonstrate that the effects of sibship size and birth order previously shown in children and adolescents (Belmont and Marolla, Science 182:1096–1101, 1973; Zajonc and Markus, Psych Rev 82:74–88, 1975; Zajonc, Am Psychol 56:490–496, 2001) are robust over time and hold over a large adult range.

A formalisation of violation, error recovery, and enforcement in the bit transmission problem

The design of complex multi-agent systems is increasingly having to confront the possibility that agents may not behave as they are supposed to. In addition to analysing the properties that hold if protocols are followed correctly, it is also necessary to predict, test, and verify the properties that would hold if these protocols were to be violated. We illustrate how the formal machinery of deontic interpreted systems can be applied to the analysis of such problems by considering three variations of the bit transmission problem. The first, an example in which an agent may fail to do something it is supposed to do, shows how we deal with violations of protocols and specifications generally. The second, an example in which an agent may do something it is not supposed to do, shows how it is possible to specify and analyse remedial or error-recovery procedures. The third combines both kinds of faults and introduces a new component into the system, a controller, whose role is to enforce compliance with the protocol. In each case the formal analysis is used to test whether critical properties of the system are compromised, in this example, the reliable communication of information from one agent to the other.     

Measuring the quality of the sibling relationship during middle childhood: The psychometric properties of the Sibling Relationship Inventory

To address a significant gap in the literature on sibling relationships, the present study examined the psychometric properties of the Sibling Relationship Inventory (SRI) in an Italian sample. The study had three main aims: (i) to investigate the factorial structure of the SRI; (ii) to evaluate the invariance of the SRI's factorial structure across birth order; and (iii) to test the SRI's validity. To this end 385 children, 213 first-borns and 172 second-borns (aged 6 to 12) were recruited. Confirmatory factor analyses showed a three-factor structure identical to that reported by the authors of the SRI. Critically, the SRI structure was stable when first- and second-borns were considered separately. Overall, the Italian version of the SRI showed good psychometric properties.     

Exploring the forgetting mechanisms in working memory: Evidence from a reasoning span test

In working memory (WM) span tests participants have to maintain to-be-remembered information while processing other, potentially distracting, information. Previous studies have shown that WM span scores are greater when span lists start with a long processing task and end with a short processing task than when these processing tasks are presented in the reverse order (e.g., Towse, Hitch, & Hutton, 2000). In Experiment 1, we obtained a similar stimulus order effect in a reasoning span test, using reasoning sentences that were equated for length in terms of the number of constituent words, but which differed in processing complexity; span scores were greater when lists began with a complex sentence and ended with a simple sentence than when this stimulus order was reversed. In Experiment 2, the stimulus order effect was not found when processing duration was held constant while sentence complexity was varied using a computer-paced moving window presentation paradigm. These results suggest that duration-based constraints can affect degree of forgetting independently of the load generated during processing phases in WM span performance and therefore imply that time-related forgetting can occur in WM span tests, particularly when the difficulty of the processing component blocks active maintenance of to-be-remembered material.
