Atttudes and behavior: Implications of attitudes toward behavioral alternatives

The relationship between attitudes and behavior was considered. An attitudinal model of behavioral alternatives was presented and its applied and theoretical implications explicated. Three investigations were reported that tested the initial viability of the approach. Support for the model was observed in all three investigations.     

Some theory and results for metrics for bounded response scales

In an earlier note, a new metric for bounded response scales (MBR) was introduced which resembles the city-block metric but is bounded above. It was suggested the MBR may be more appropriate than minkowski metrics for data obtained with bounded response scales. In this article, some formal properties of the MBR are investigated and it is shown that it is indeed a metric. Empirical predictions are then derived from the MBR and contrasted with those of a “monotonicity hypothesis,” which holds that dissimilarity judgements tend to be biased towards overestimation of larger distances, and with the predictions of the minkowski metrics, which imply additivity of collinear segments. Some empirical results are presented which contradict the monotonicity hypothesis and the minkowski metrics, and favor the MBR. Finally, the logic used to motivate the MBR is invoked to define a subadditive concatenation for bounded norms in the one-dimensional case, which may be useful in psychophysical work where the upper bounds are often real, rather than due to the response scale. This concatenation predicts understimation for doubling and overestimation for halving and middling tasks.     

Further study of the electrophysiological correlates of lexical decision

Discriminations were required between words, pseudohomophones, and visually matched nonwords. Two tasks were employed, one which could be accomplished on the basis of a visual code (the REAL task, involving discrimination between words and both types of nonword) and another necessitating the use of a phonological code (the REAL/PSEUD task, words and pseudohomophones vs. nonwords). ERPs were recorded from three midline sites and from left and right inferior parietal sites. Two principal results were observed, (i) the peak latency of a late positive component, P637, covaried with RT, with variations in latency of around one half the corresponding RT variations, and (ii) the peak-to-peak amplitude of N100-P187 interacted with stimulus and task, such that it was larger for nonwords in the REAL task and words in the REAL/PSEUD task. No taskor stimulus-dependent asymmetries were observed in any ERP component. The P637 latency data support a model of RT variation based on the interaction of changes in parallel response preparation and stimulus evaluation processes. The observations with respect to N100-P187 suggest that ERPs are sensitive to factors related to the early processing of words and word-like visual material.     

Emotional stability as a major dimension of happiness

Happiness is associated with both extraversion and neuroticism, and extraversion is generally considered the more important. A recent study of happy introverts has shown that extraversion is not always an essential correlate of happiness, and an extensive meta-analysis has found that neuroticism is a greater predictor of both happiness and life satisfaction. It is suggested that the reason for the importance of neuroticism having been overlooked in the past, is the difficulty of handling the idea that (positive) happiness is related to the absence of a (negative) construct. This difficulty could be resolved by the reversal of neuroticism into an alternative and positive concept of “emotional stability”. Happiness could then be regarded as being associated with two positive qualities. With this change of emphasis, a short empirical study has been made of the relationships between happiness as measured by the Oxford Happiness Inventory (OHI) and extraversion and emotional stability. In bivariate and partial correlation, emotional stability was more strongly associated with happiness than extraversion, and accounted for more of the total variability in multiple regression. Emotional stability was also the greater correlate for a majority of the 29 items of the OHI, and the sole significant predictor of the happiness of younger people.

心理测验中个人拟合研究的回顾与展望

个人拟合研究是对心理测验中偏差行为鉴别的一种新方法,它以Guttman理想模型、项目反应理论和非参数项目反应理论为基础。传统个人拟合指标是对宽泛偏差行为的检验,当前个人拟合研究更具体、更形象,针对于某种偏差行为的专门性指标和图形与回归分析受到了越来越多的关注。但无论哪种个人拟合方法都会受到各种无关因素的影响,如何克服这些影响,提高个人拟合方法的实际应用价值将成为个人拟合研究的主要方向

On the Structure of the Non-dominated Set for Bicriteria Programmes

In multiple-objective programming, a knowledge of the structure of the non-dominated set can aid in generating efficient solutions. We present new concepts which allow for a better understanding of the structure of the set of non-dominated solutions for non-convex bicriteria programming problems. In particular, a means of determining whether or not this set is connected is examined. Both supersets and newly defined subsets of the non-dominated set are utilized in this investigation. Of additional value is the use of the lower envelope of the set of outcomes in classifying feasible points as (properly) non-dominated solutions.
