Connectionist attention to variables has been too restricted in two ways. First, it has not exploited certain ways of doing without variables in the symbolic arena. One variable-avoidance method, that of logical combinators, is particularly well established there. Secondly, the attention has been largely restricted to variables in long-term rules embodied in connection weight patterns. However, short-lived bodies of information, such as sentence interpretations or inference products, may involve quantification. Therefore short-lived activation patterns may need to achieve the effect of (...) variables. The paper is mainly a theoretical analysis of some benefits and drawbacks of using logical combinators to avoid variables in short-lived connectionist encodings without loss of expressive power. The paper also includes a brief survey of some possible methods for avoiding variables other than by using combinators. (shrink)

Modality specificity in priming is taken as evidence for independent perceptual systems. However, Easton, Greene, and Srinivas (1997) showed that visual and haptic cross-modal priming is comparable in magnitude to within-modal priming. Where appropriate, perceptual systems might share like information. To test this, we assessed priming and recognition for visual and auditory events, within- and across- modalities. On the visual test, auditory study resulted in no priming. On the auditory priming test, visual study resulted in priming that was only (...) marginally less than within-modal priming. The priming results show that visual study facilitates identification on both visual and auditory tests, but auditory study only facilitates performance on the auditory test. For both recognition tests, within-modal recognition exceeded cross-modal recognition. The results have two novel implications for the understanding of perceptual priming: First, we introduce visual and auditory priming for spatio-temporal events as a new priming paradigm chosen for its ecological validity and potential for information exchange. Second, we propose that the asymmetry of the cross-modal priming observed here may reflect the capacity of these perceptual modalities to provide cross-modal constraints on ambiguity. We argue that visual perception might inform and constrain auditory processing, while auditory perception corresponds to too many potential visual events to usefully inform and constrain visual perception.

Research on values is extensive. Values and value systems are concepts that have interested researchers across domains such as psychology, sociology, and anthropology. However, antecedents of values have not received sufficient attention. In this study, we develop and assess a personal value system from the ancient texts of India. The texts describe a system of existential beliefs and values or prescriptive beliefs. Existential beliefs are concerned with the nature of reality. Prescriptive beliefs or values follow from these existential beliefs, and (...) behavior is influenced by values. The content of existential beliefs and the implied values or prescriptive beliefs are extracted from the texts and a conceptual model of the belief system is developed. Scales are constructed and administered to a sample of subjects. Responses from the survey are analyzed using a structural equation modeling framework. Confirmatory factor analysis is used to assess the scales and establish their adequacy. The nomological net of existential beliefs and values is empirically assessed, and construct validity is examined. Results support the belief system described in the texts. (shrink)
