RALPH WENDELL BURHOE: HIS LIFE AND HIS THOUGHT

Abstract. The fourth installment from the author's book-length study of Ralph Wendell Burhoe's life and thought sets forth the substance of his intellectual theological program. Constructed with the intention of laying the foundation for behavior that conforms to the requirements for survival as laid down by the reality system of which we are part, it also aims to provide motivation for such behavior. The heart of the program is formed by concepts of God and soul. The concept of God grounds an understanding of a reality system upon which we are dependent and to which we must conform whereas the concept of soul gives assurance that our behavior does make a difference and that our contributions to the reality system possess an everlasting quality.     

Sequential responding to arabic numerals with wild cards by the chimpanzee (Pan troglodytes)

One adult female chimpanzee (Pan troglodytes) was trained to respond serially to three arabic numerals between 1 and 9, presented on a cathode-ray-tube (CRT) screen. To examine the factors affecting her sequential responding behavior, wild-card items were added to the three-item sequences. When this wild-card item remained until the subject responded to the last numeral (i.e., the terminator condition), her response to the terminator at each point of the sequence was controlled by the ordinal distance between numerals. Thus, the number of responses to the terminator increased as the ordinal distance between numerals increased. When the wild-card item was eliminated by the subject’s response (wild-card conditions), the probability of responses to the wild card before the first numeral increased as a function of the serial position of the first numeral. These results were consistent with previous studies of response time and suggest both serial position and symbolic distance effects. It is suggested that the subject might form the integrated 9-item linear representations by training of possible subsets of three-item sequences. Knowledge concerning the ordinal position of each numeral was established through this training. Received: 27 October 1999 / Accepted: 22 November 1999     

A probabilistic model of semantic plausibility in sentence processing

Experimental research shows that human sentence processing uses information from different levels of linguistic analysis, for example, lexical and syntactic preferences as well as semantic plausibility. Existing computational models of human sentence processing, however, have focused primarily on lexico-syntactic factors. Those models that do account for semantic plausibility effects lack a general model of human plausibility intuitions at the sentence level. Within a probabilistic framework, we propose a wide-coverage model that both assigns thematic roles to verb–argument pairs and determines a preferred interpretation by evaluating the plausibility of the resulting ( verb , role , argument ) triples. The model is trained on a corpus of role-annotated language data. We also present a transparent integration of the semantic model with an incremental probabilistic parser. We demonstrate that both the semantic plausibility model and the combined syntax/semantics model predict judgment and reading time data from the experimental literature.     

Mapping numerical magnitudes onto symbols: the numerical distance effect and individual differences in children's mathematics achievement

Although it is often assumed that abilities that reflect basic numerical understanding, such as numerical comparison, are related to children’s mathematical abilities, this relationship has not been tested rigorously. In addition, the extent to which symbolic and nonsymbolic number processing play differential roles in this relationship is not yet understood. To address these questions, we collected mathematics achievement measures from 6- to 8-year-olds as well as reaction times from a numerical comparison task. Using the reaction times, we calculated the size of the numerical distance effect exhibited by each child. In a correlational analysis, we found that the individual differences in the distance effect were related to mathematics achievement but not to reading achievement. This relationship was found to be specific to symbolic numerical comparison. Implications for the role of basic numerical competency and the role of accessing numerical magnitude information from Arabic numerals for the development of mathematical skills and their impairment are discussed.     

Self-Interest, Symbolic Attitudes, and Support for Public Policy: A Multilevel Analysis

This paper examines the role of self-interest and symbolic attitudes as predictors of support for two domestic policy issues—guaranteed jobs and incomes and national health insurance—in the American National Election Survey (ANES) between 1972 and 2004. As was the case in 1976 when Sears, Lau, Tyler, and Allen (1980 ) first explored this topic, symbolic attitudes continue to be much more important predictors of policy attitudes than various indicators of self-interest over the 30 years we analyze. We explore this finding further to determine whether any individual/internal and external/contextual variables affect the magnitude of self-interest effects on policy support. Five possible internal moderators of self-interest effects are examined: (1) political knowledge, (2) issue publics, (3) political values, (4) social identifications, and (5) emotions, but none are found to boost the magnitude of the self-interest effect. However, we do find some evidence that contextual variables representing the social/information environment moderate the impact of self-interest on public opinion.     

The Crystallization of Contemporary Racial Prejudice across the Lifespan

The conventional wisdom is that racial prejudice remains largely stable through adulthood. However, very little is known about the development of contemporary racial attitudes like symbolic racism. The growing crystallization of symbolic racism through the lifespan is tested using two data sets that measure the stability, consistency, and predictive validity of symbolic racism in samples ranging in age from young adults to the elderly. The results provide evidence that the crystallization of symbolic racism generally takes on a curvilinear trajectory across the lifespan, showing that it is already largely crystallized by voting age, that it continues to crystallize still further through adulthood and that it begins to decline in coherence in late adulthood. The results generally provide evidence confirming early speculations of symbolic racism theorists concerning the crystallization of symbolic racism across the lifespan and are discussed in terms of different theoretical perspectives on the relationship between aging and attitudes more generally.     

Why Do White Americans Oppose Race‐Targeted Policies? Clarifying the Impact of Symbolic Racism

Measures of symbolic racism (SR) have often been used to tap racial prejudice toward Blacks. However, given the wording of questions used for this purpose, some of the apparent effects on attitudes toward policies to help Blacks may instead be due to political conservatism, attitudes toward government, and/or attitudes toward redistributive government policies in general. Using data from national probability sample surveys and an experiment, we explored whether SR has effects even when controlling for these potential confounds and whether its effects are specific to policies involving Blacks. Holding constant conservatism and attitudes toward limited government, SR predicted Whites' opposition to policies designed to help Blacks and more weakly predicted attitudes toward social programs whose beneficiaries were racially ambiguous. An experimental manipulation of policy beneficiaries revealed that SR predicted policy attitudes when Blacks were the beneficiary but not when women were. These findings are consistent with the claim that SR's association with racial policy preferences is not due to these confounds.     

Perceived collective continuity and ingroup identification as defence against death awareness

Perhaps unique among the animal species, humans are aware that they will ultimately die. Terror management theory (TMT) posits that investing in a social group helps people to manage paralysing anxiety stemming from death awareness. In line with this proposition, research to date has shown that when reminded of their own mortality, people increase their identification with a relevant group and defend its beliefs, values, and practices. In the reported study, we demonstrate that a mortality salience induction enhances people’s perceptions of group temporal endurance—or perceived collective continuity (PCC), as we define it. Enhanced PCC leads, in turn, to enhanced group identification. This is in line with the TMT assumption that death awareness leads people to invest in a social group because this constitutes a temporally enduring meaning-system that imbues life with meaning, order, and permanence, and promises death transcendence to those who meet the prescribed standards of value.     

Are we born and do we die?

The stranglehold on our imagination by the mind-body dualisms that permeate the culture is such that most people seem to suppose that "body" and "soul" name distinct and separable entities. Resisting such dualisms in favour of an old-fashioned Aristotelean view of the soul as the form of the body, this essay considers two questions: do human parents produce human beings, and do human beings die? The doctrine of the special creation of the individual soul seems to require us to answer the first question in the negative because, according to this doctrine, parents only produce matter for the God-given soul to form. As to the second, many people seem to suppose that human beings do not die, only their bodies do. Arguing against the view that immortality is a natural property of human minds, the essay suggests (with the help of Joseph Ratzinger) that, whether we speak of "immortality" or of "resurrection", life from death is neither nature, nor achievement, but gift.     

Children’s representation of symbolic magnitude: The development of the priming distance effect

The comparison distance effect (CDE), whereby discriminating between two numbers that are far apart is easier than discriminating between two numbers that are close, has been considered as an important indicator of how people represent magnitudes internally. However, the underlying mechanism of this CDE is still unclear. We tried to shed further light on how people represent magnitudes by using priming. Adults have been shown to exhibit a priming distance effect (PDE), whereby numbers are processed faster when they are preceded by a close number than when they are preceded by a more distant number. Surprisingly, there are no studies available that have investigated this effect in children. The current study examined this effect in typically developing first, third, and fifth graders and in adults. Our findings revealed that the PDE already occurs in first graders and remains stable across development. This study also documents the usefulness of number priming in children, making it an interesting tool for future research.
