Normative indications for Xhosa speaking unskilled workers on the Rey–Osterrieth Complex Figure Test

The aim of this study was to establish normative indications for the Rey-Osterrieth Complex Figure (RCF) copy, incidental recall and delayed recall tasks, administered in English on a non-clinical population of Xhosa, unskilled workers (N?=?33) (females n?=?21; males n?=?12), with a background of relatively disadvantaged quality of education up to Grades 11 and 12. The sample was stratified into two age groupings (18 – 29 years, n?=?17; 30 – 40 years, n?=?16), equally distributed for sex and level of education. Within group statistical analyses compared subgroup test performances for sex and age within the total sample. Between group analyses were used to compare the performance of the present sample with age equivalent data derived from a meta-analysis of US normative data on the RCF task. There was an age effect in favour of the younger group for both the immediate and delayed recall tasks. The local data for all RCF tasks were significantly lower than the US normative data, with the indication that higher levels and/or quality of formal school education might advantage performance on this complex visuoperceptual copy and recall task.     

What's Scene and Not Seen: Influences of Movement and Task Upon What We See

Studies concerning the processing of natural scenes using eye movement equipment have revealed that observers retain surprisingly little information from one fixation to the next. Other studies, in which fixation remained constant while elements within the scene were changed, have shown that, even without refixation, objects within a scene are surprisingly poorly represented. Although this effect has been studied in some detail in static scenes, there has been relatively little work on scenes as we would normally experience them, namely dynamic and ever changing. This paper describes a comparable form of change blindness in dynamic scenes, in which detection is performed in the presence of simulated observer motion. The study also describes how change blindness is affected by the manner in which the observer interacts with the environment, by comparing detection performance of an observer as the passenger or driver of a car. The experiments show that observer motion reduces the detection of orientation and location changes, and that the task of driving causes a concentration of object analysis on or near the line of motion, relative to passive viewing of the same scene.     

An Analysis of Certain Effects of Bilateral Temporal Lobectomy in the Rhesus Monkey,with Special Reference to “Psychic Blindness”

Southern, black, poverty-level, female subjects were classified as Actives, Dropouts, or Never-Beens in regard to attendance at a family-planning clinic. The subjects took a story-telling test designed for lower social class subjects and rated a variety of persons and activities along semantic differential dimensions. Women who had dropped out were significantly lower than the other groups in their needs for achievement and for controlling life events. Actives perceived more difficulty in controlling events. Several significant differences were also found in the semantic differential ratings. The results can be interpreted to yield a consistent set of hypotheses about motivations related to birth control decisions.     

A Tachistoscopic Device for Work with Subhuman Primates

The present study examined predictors of siblings’ relations in 202 young adults (aged 21–32 years), who completed the Adult Sibling Relationship Questionnaire and the Narcissistic Personality Inventory. Results indicate that warmth between siblings is explained by gender (with women feeling closer), perceived paternal favoritism, low levels of narcissism, and an interaction suggesting that paternal favoritism moderates the link between narcissism and sibling warmth. Conflict between siblings was explained by gender (sisters), age, parental favoritism, high levels of narcissism, extreme levels of similarity or dissimilarity between siblings, and interactions indicating that older age is a predictor of conflict between siblings among women but not among men. The impact of parental favoritism and narcissism on sibling relationships in young adulthood was discussed.

The neural correlates of reward-related trial-and-error learning: an fMRI study with a probabilistic learning task

This fMRI study investigated the neural correlates of reward-related trial-and-error learning in association with changing degrees of stimulus-outcome predictabilities. We found that decreasing predictability was associated with increasing activation in a frontoparietal network. Only maximum predictability was associated with signal decreases across the learning process. The receipt of monetary reward revealed activation in the striatum and associated frontoparietal regions. Present data indicate that during reward-related learning, high uncertainty forces areas relevant for cognitive control to remain activated. In contrast, learning on the basis of predictable stimulus-outcome associations enables the brain to reduce resources in association with the processes of prediction.     

Suszko’s Thesis,Inferential Many-valuedness,and the Notion of a Logical System

According to Suszko’s Thesis, there are but two logical values, true and false. In this paper, R. Suszko’s, G. Malinowski’s, and M. Tsuji’s analyses of logical twovaluedness are critically discussed. Another analysis is presented, which favors a notion of a logical system as encompassing possibly more than one consequence relation.

Erica Fox Brindley,Music, Cosmology,and the Politics of Harmony in Early China.

Chinese music is a broad topic that includes a wide variety of methodological premises, which music historians, ethnomusicologists, music theorists, and systematic musicologists can use for fruitful exploration. In her book Music, Cosmology, and the Politics of Harmony in Early China （MCPH, hereafter）, Erica Fox Brindley, who is an intellectual and cultural historian of early China, undertakes an historical approach and works out the role of musical sound in the social, natural, and religious order. She explores ＂the role of music, and even sound itself, as both an agent and indicator of moral, orderly, and cosmically balanced rule＂ （42）. Based on early imperial texts Brindley points out that already during the Warring States period （481-221BC） sound （sheng 声） is clearly a component of the cosmos and later, during the Han Dynasty （202BC-220AD）, possesses special cosmic efficacy （69）. The concept of sheng plays an important role in her explanations of the cosmological and political aspects of music,
