Improved standards for laboratory animals?

In February 1993, Judge Charles R. Richey of the United States District Court issued a summary judgment in the case of Animal Legal Defense Fund, et al. v. The Secretary of Agriculture, et al. The decision, which was in favor of the Animal Legal Defense Fund, requires the U.S. Department of Agriculture to withdraw its current regulations governing exercise for dogs and the psychological well-being of nonhuman primates used for biomedical research and to issue new regulations containing only minimum, measurable standards. Both plaintiffs and defendants contended that they were seeking the best interests of the laboratory animals. The issue at stake is whether animals are better protected if the government establishes limited minimal standards or is allowed to require institutions to provide additional standards, which will be judged on the basis of their effectiveness in maintaining healthy animals. The Court avoided this dispute, however, by placing primary emphasis on applying the Administrative Procedures Act and stating that it was merely interpreting the "plain meaning" of the Animal Welfare Act, as amended. In this article, arguments are presented for interpreting the law in a far more flexible way than Judge Richey did. The conclusion is also reached that there were no winners in the Animal Legal Defense Fund case and that the real losers are the laboratory animals.     

Classical Psychophysics and the Assessment of Agreement and Accuracy In Judgments of Personality

ABSTRACT The just noticeable difference (jnd) unit of classical psycho-physics is introduced as a new way to describe accuracy and agreement in observer evaluations of personality. A formula for estimating jnd's from typically available summary statistics is derived from Thurstone's law of comparative judgment. A study examining four traits judged in 10 samples of subjects where the design permitted the calculation of jnd's by the method of paired comparisons indicated that the formula predicted the empirically derived jnd's associated with the mean judge ratings with considerable precision. Jnd's of criterion measures were also predicted, and while fit was somewhat less impressive in this case, there was still appreciable convergence between predicted and empirical values. The implications of jnd measures of agreement and accuracy are discussed. These implications include (a) possibilities for increased understanding of bias in observer judgments, (b) a new recognition that equal correlations to external criteria do not necessarily imply equal accuracy, and (c) alternative ways of describing the magnitude of effect in psychological research.     

Relevant consequence and empirical inquiry

A criterion of adequacy is proposed for theories of relevant consequence. According to the criterion, scientists whose deductive reasoning is limited to some proposed subset of the standard consequence relation must not thereby suffer a reduction in scientific competence. A simple theory of relevant consequence is introduced and shown to satisfy the criterion with respect to a formally defined paradigm of empirical inquiry.Research support was provided by the Office of Naval Research under contract No. N00014-89-J-1725 to Osherson and Weinstein, Swiss National Science Foundation under contract No. 21-32399.91 and by a Siemens Corporation grant to Osherson.     

Adult Age and Gender Differences in Eyewitness Recall in Field Settings1

Six-hundred-fifty-one citizens were stopped in public places and tested for prompted recall of physical characteristics of a young woman to whom they had spoken for approximately 15 s, 2 min earlier. Recall differed as a function of the two targets used on five of eight characteristics, but no significant differences were found for either target as a function of the gender or age group of the witnesses. Young adults (18-29 years of age) in general were superior to middle-aged adults (30-44), who in turn were superior to older adults (45-65). Women were significantly more accurate than men in accuracy of recall for weight, and for characteristics judged to be more important than less important for person memory. Male and female witnesses were equally confident in their recall performance. Young and middle-aged groups were significantly more confident in recall than the oldest group. Significant correlations were found between confidence and accuracy of recall for men and for women, and for each age group. Women made significantly longer duration estimates of the encounters with the targets than did men. Men overestimated the duration by a 2:1 ratio, and women overestimated by a 3:1 ratio. No significant correlations were found between accuracy of duration estimates and confidence in reports. The results were interpreted in terms of their forensic importance.     

Parental functioning and children's adjustment in families of divorce: A prospective study

This paper prospectively examined relations between marital status, predivorce parenting practices, and children's adjustment, using data from the New York Longitudinal Study (NYLS). Prospective analyses of children's predivorce adjustment indicated that neither boys nor girls showed more problematic behavior prior to parental separation, and only boys had more difficulties after divorce. However, parents of to-be-divorced families reported more difficulties in childcare practices before divorce than did parents of always-married families. Parenting difficulties in to-be-divorced families were found consistently for boys but not for girls. Results suggest that the difficulties found among boys after divorce may be linked with parenting problems that begin before divorce.The authors are indebted to Alexander Thomas and Stella Chess, the original investigators of the project.

The thin ideal, depression and eating disorders in women

It is proposed that a cultural ideal of thinness for women causes depression at a higher rate among women than among men. This model accounts for five currently unintegrated trends in the epidemiology of depression. It explains why: (1) twice as many women as men are likely to be depressed; (2) this sex difference emerges at puberty; (3) this sex difference is only found in western countries; (4) there is more depression today; (5) the average age of onset for depression is younger now than in the past. Four parallel trends in eating disorders can also be accounted for by the same factor.     

The Influence of Verbal Responses to Common Greetings on Compliance Behavior: The Foot-In-The-Mouth Effect

This study reports the results of three field experiments which demonstrate that asking someone how they feel, having them verbally respond, and then acknowledging that response, facilitates compliance with a charitable request. The findings are discussed with respect to the influence of public commitments on behavioral consistency.
Before you ask anyone for a donation, you first ask them how they're feeling. After they tell you they're feeling good, and you tell them you're glad they're feeling good, the/11 be more likely to contribute to helping someone who isn't.     

Naming consistency in Alzheimer''s disease

Although lexical semantic deficits are postulated to play a prominent role in the anomia of Alzheimer's disease, it is unclear whether the primary disturbance is one of lexical access or one of lexical semantic loss. Response consistency on a naming task is one means of evaluating the underlying source of naming impairment. Access dysfunction usually implies variable word-finding difficulty, while a theory of lexical loss predicts that many word names would be consistently unavailable. Nineteen Alzheimer's disease patients were administered a visual confrontation naming task (the Boston Naming Test) on two occasions 6 months apart. Eighty percent of errors occurred consistently at both times; only 20% of errors occurred on only one occasion. Response consistency occurred significantly more often than expected under the assumption of no response consistency. Findings support the hypothesis that anomia in Alzheimer's disease is in part due to a loss of lexical semantic information.
