Scientific analysis of Buddhism and a comparative study of Buddhism and science

As Buddhism spread into China, the Mahayana (Dacheng) and Hinayana (Xiaocheng) schools, as well as the kong 空 (empty) or you 有 (being) schools, each developed separately, with all sorts of competing theories emerging. While Chinese Buddhism saw a revival in modern times, Western science also gained ground all over the country, and many scholars, technologists and monks sought to interpret the meaning of kong according the achievements and method of the natural sciences. They used science to interpret the content and methods of Buddhist teachings, ontology, and outlook on life. Of the scholars who did so, Wang Jitong (王季同) and You Zhibiao (尢智表) are the most excellent. __________ Translated from Pumen Xuebao 普门学报 (Universal Gate) Vol. 27, 2005 (5) by Kong Xiangzhen, Ma Tianxiang, and Andrew Herron     

Retrieval processes in fifth graders and adults

This research was concerned with retrieval processes which underlie conceptual clustering. In a free recall task with categorized lists, fifth graders' and adults' retrieval was examined temporally by means of interword response times. List organization and retrieval cue factors were manipulated in order to assess the developmental relevance of an hypothesized three component retrieval model. The results indicated that both age groups used a qualitatively similar retrieval strategy, involving search for and decoding of higher-order memory units. Providing retrieval cues eliminated the category search component, but also increased the likelihood of exhaustive recall attempts under random presentation conditions. The results were discussed in terms of the inter-relationships between storage and retrieval strategies. Age-related differences in retrieval time were attributed to insufficient reorganization during input and failure to attempt to recall all of a category's members.     

Convergence between attention variables and factors of psychometric intelligence in older adults

The purpose of the present study was to examine the hypothesis that individual differences on measures of attention would converge with select factors of psychometric intelligence, especially fluid intelligence and short-term acquisition and retrieval. A sample of 83 elderly adults $\text{(}\text{X}\text{= 71}\text{years}\text{)}$ was administered a battery of 17 psychometric ability tests. Tests were selected to mark four psychometric ability factors (Cattell and Horn's dimensions of fluid and crystallized intelligence, short-term acquisition and retrieval, and perceptual speed). Also, seven tasks representing four aspects of attention—decoding processes, selective attention, attention switching, and concentration—were administered. A confirmatory factor analysis was conducted to examine the relationships among the four psychometric ability factors and 11 variables obtained from the attention tasks. Results were only partially consistent with the hypothesized pattern of convergence. Two attention measures had significant loadings on a fluid-type intelligence factor, and one had a marginally significant loading on a short-term memory factor. In general, the greatest convergence occured between attention variables and the ability factor of Perceptual Speed. Results were discussed with respect to previous research on psychometric abilities and cognitive processes, the theory of fluid-crystallized intelligence, and their implications for understanding intellectual aging.     

Structuring decision problems and the ‘bias heuristic’

This paper examines our understanding of the decomposition of immediate acts when structuring decision problems. Seven different types of uncertainties are identified, and four of these are shown to be taken explicitly into account in models within the province of decision theory, described in terms of four interlocking systems interfaced with semantic memory (a core act-event system, and systems buffering utilities, probabilities and events, respectively). Requisite decision modeling is shown to require that the remaining three types of uncertainty (procedural uncertainty; how the decision maker will feel about subsequent acts; agency for changing subsequent states of the world) are also resolved. Methods for ‘fixing’ structure are discussed in terms of aiming at a common understanding about the ‘small world’ in which a decision problem is located. Difficulties in resolving uncertainties in doing this are described. An alternative approach, common in studies invoking ‘behavioural decision theory’ is contrasted: imposing structure, assuming common understanding. The latter approach is shown to involve (i) the ‘naturalisation’ of the small world in which the decision problem is located, and (ii) the utilisation of normative models as ‘ideal types’, leading to the use of the ‘bias’ argument in discussing subjects' performance in decision tasks. Using this argument reflexively, the operation of the ‘bias heuristic’ is identified in a survey of published papers referencing this approach to the study of decision making. Effects identified are: availability of tasks, subjects and explanations; representativeness of findings; and anchoring and adjustment of explanations. Implications for practice are discussed throughout the paper.     

Self-punitive behavior in humans: Effects of a self-fulfilling prophecy

Human subjects were exposed to contingencies which programmed aversive tones (100 db). Two types of contingencies were employed: self-confirming (i.e., self-fulfilling prophecies), in which the aversive tone was occasioned by the prediction it was about to occur; and self-disconfirming, in which the tone was probable when subjects predicted it would not occur. Experiments 1 and 2 used a modified classical conditioning paradigm, and demonstrated that a self-confirming contingency maintained reliable self-punitive responding, i.e., subjects consistently predicted and therefore obtained tones on every trial. Subjects in Experiment 3 were instructed to express predictions continuously throughout four sessions to ensure adequate sampling of the various predictions. Subjects exposed to a self-disconfirming contnngency reliably evidenced awareness of the contingency in effect (judged by answers on a postexperimental questionnaire), whereas subjects exposed to a self-confirming contingency failed to show effective avoidance behavior or contingency awareness. Experiment 4 investigated free-operant self-punitive behavior, utilizing a single prediction response button, which subjects depressed repeatedly. Subjects were exposed to either periodic or aperiodic punishment schedules over as many as four sessions. In general, more persistent self-punitive responding was found in the groups receiving periodic punishment. The results from the four experiments show that self-confirming contingencies can effectively prolong self-punitive responding in human subjects. The findings are consistent with a blocking interpretation of self-punitive behavior, which asserts that when an aversive event is already predicted by stimuli in the situation (including temporal cues), the association between a response and punishment is impaired, and self-punitive responding is likely to be maintained. An integration of human and animal self-punitive research is proposed.
