Stressful life events and use of physician services among the elderly: the moderating role of pet ownership

The physician utilization behavior of 938 Medicare enrollees in a health maintenance organization was prospectively followed for 1 year. With demographic characteristics and health status at baseline controlled for, respondents who owned pets reported fewer doctor contacts over the 1-year period than respondents who did not own pets. Furthermore, pets seemed to help their owners in times of stress. The accumulation of prebaseline stressful life events was associated with increased doctor contacts during the study year for respondents without pets. This relationship did not emerge for pet owners. Owners of dogs, in particular, were buffered from the impact of stressful life events on physician utilization. Additional analyses showed that dog owners in comparison to owners of other pets spent more time with their pets and felt that their pets were more important to them. Thus, dogs more than other pets provided their owners with companionship and an object of attachment.     

Characteristics of the indirect McCollough effect

Induction of contingent color aftereffects with a single chromatic grid sometimes results in an illusory color on a grid different from the one presented during induction. Such illusory color, contingently elicited by a noninduced grid, has been termed the indirect McCollough effect (indirect ME). We show that the indirect ME occurs only when the color complementary to the grid color is present during induction (either physically present or as a color afterimage), and that the indirect ME is seen only on gratings that are orthogonal to the induction orientation. These findings are in accord with the account of the indirect ME proposed by Humphrey, Dodwell, and Emerson (1989). We also show that characteristics of the indirect ME (seen following one-grid induction), both on induced and orthogonal orientations, are similar to those observed with the direct ME (seen following the usual two-grid induction procedure). Both procedures result in contingent aftereffects that display substantial retention and that do not display interocular transfer.     

Elevation: A review of scholarship on a moral and other-praising emotion

The term elevation (also referred to as moral elevation), described by Thomas Jefferson and later coined by Jonathan Haidt, refers to the suite of feelings people may experience when witnessing an instance of moral beauty. The construct of elevation signifies the emotion felt when a person is a witness to, but not a recipient of, the moral behavior of others. Scholarship examining elevation has burgeoned since Haidt first introduced the construct. Researchers have explored the antecedents of, and outcomes associated with, witnessing instances of moral beauty. The current review will outline the existing scholarship on elevation, highlight conflicting findings, point out critical gaps in the current state of elevation research, and delineate fertile future directions for basic and applied research. Continued investigation of the affective, motivational, and behavioral responses associated with witnessing virtuous actions of others is warranted.     

Faith versus practice: different bases for religiosity judgments by Jews and Protestants

Jewish tradition is focused much more on religious practice than on religious belief, whereas various denominations of Christianity focus about equally on religious practice and on faith. We explored whether this difference in dogma affects how Jews and Protestants judge religiosity. In Study 1, we showed that Jews and Protestants rated practice equally important in being religious, while Protestants rated belief more important than did Jews. In Study 2, Jewish participants' self‐rated religiosity was predicted by their extent of practice but not knowledge of Judaism or religious beliefs. In contrast, in Study 3, Protestants' self‐rated religiosity was predicted both by their extent of practice and belief, but not knowledge. In all, the results show that Jews and Protestants view the importance of practice in being religious similarly, but that belief is more important for Protestants.

Occasion setting and drug tolerance

There is considerable evidence that drug-paired cues become associated with drug effects. It has been hypothesized that these cues act as Pavlovian conditional stimuli (CSs), and elicit conditional compensatory responses that contribute to tolerance. On the basis of a conditioning analysis of tolerance, we would expect that is should be possible to establish drug-paired cues as occasion setters, as well as conditional stimuli. Using feature-positive discrimination training, we evaluated the contribution of occasion-setting stimuli (as well as CSs) to tolerance to the hypothermic effect of ethanol in rats. The results indicated that a complete associative analysis of drug tolerance should incorporate not only the CS properties of predrug cues, but also the occasion-setting properties of such cues. The findings have implications for interpreting conflicting findings concerning extinction of tolerance and for cue-exposure treatments of addiction.     

A Survey of Management Educators’ Perceptions of Unethical Faculty Behavior

To help academic associations in management develop, refine, and implement a code of ethics, we conducted a survey of management educators’ perception of the ethicality of 142 specific behaviors in teaching, research, and service. The results of the survey could be used to inform ethics committees of these associations regarding the level of acceptability of such conduct. The potential value of our study for the Academy of Management or similar management associations lie in our (1) systematically involving the members in building support for the code of ethics, (2) assessing members’ ethical judgments on both cross-sectional and longitudinal bases so as to identify areas needing particular attention in ethical training, (3) providing an extensive list of specific examples of questionable and potentially unethical behaviors so as to make it easier to implement the code, and (4) providing a template survey document for potential use in involving more stakeholder groups in the development of codes of ethics.

Rationality,Reasonableness, and Critical Rationalism: Problems with the Pragma-dialectical View

A major virtue of the Pragma-Dialectical theory of argumentation is its commitment to reasonableness and rationality as central criteria of argumentative quality. However, the account of these key notions offered by the originators of this theory, Frans van Eemeren and Rob Grootendorst, seems to us problematic in several respects. In what follows we criticize that account and suggest an alternative, offered elsewhere, that seems to us to be both independently preferable and more in keeping with the epistemic approach to arguments and argumentation we favor.

Exploratory behavior as a function of environmental novelty and complexity in male and female rats

Laboratory rats show a positive response to low- and nonstressful novel events. The novel event may involve a number of aspects of the stimulus field. It is usually associated with a change in amount of environmental complexity. Most studies concerning novelty-related behavior involve the introduction of novel objects or the rearrangement of familiar objects. The present purpose was to measure exploratory behavior in response to environments of increased and decreased complexity. Both directions of environmental change are conditions of novelty. A two-way manipulation of increasing and decreasing the complexity of the environment was used. Rats of both sexes showed increased exploration to exposure to novelty, no matter which manipulation was applied; however, female and male rats behaved differently to the two types of novelty. Males responded more to novelty from the introduction of an unfamiliar object. The results indicate novel stimulation, whether of increasing or decreasing complexity, has reward properties. Perhaps the male-specific behavior directed toward unfamiliar objects may serve an adaptive function.     

Reading,syntactic, orthographic,and working memory skills of bilingual Arabic-English speaking Canadian children

This study assessed the reading, language, and memory skills of 56 bilingual Arab-Canadian children age's 9-14. English was their main instructional language, and Arabic was the language spoken at home. All children attended a Heritage Language Program in Toronto where they were taught to read and write Arabic. The children were administered word and pseudo-word reading, language, and working memory tests in English and Arabic. The majority of the children showed at least adequate proficiency in both languages. There was a significant relationship between the acquisition of word and pseudo-word reading working memory, and syntactic awareness skills in the two languages. The poor readers in Arabic had lower scores on all linguistic tasks, except the visual task. There were no significant differences between bilingual English Arabic children and monolingual English-speaking children on the reading, language, and memory tasks. However, bilingual English Arabic children who had reading problems in English had higher scores on English pseudo-word reading and spelling tasks than monolingual English-speaking children with reading disabilities, probably because of positive transfer from the regular nature of Arabic orthography. In this case, bilingualism does not appear to have negative consequences for the development of language reading skills in both languages—Arabic and English—despite the different nature of the two orthographies.
