A critique of Wechsler's deterioration formula for the WAIS is offered because it neglected the important matter of significant sex differences in intellectual abilities and because it did not make optimal use of the differential test score method. Two revised formulae were devised, one for males and one for females. The female formula was much more successful than Wechsler's in maximizing deterioration slope. Recommendation is made to use the WAIS formula for men and the revised formula for women.
Many years ago it was suggested by Luckhardt and Carlson (5) that hunger is governed by a "hormone." This hypothesis developed from the observation that under certain conditions, defibrinated blood transfused from a starved dog augments the stomach contractions (hunger pangs) of the satiated recipient. Conversely, Tschukitscheff (as reported by Bash [1]) observed the inhibition of gastric motility in a starved dog following the transfusion of blood from a surfeited donor. Most recently, the hormone hypothesis has been revived by Morgan (6) and by Morgan and Stellar (7).It is to be noted that in the fashion of the day, Carlson defined hunger in terms of gastric motility. Recognizing the absence of perfect correlation between food ingestion and stomach motility, he has defended his adoption of the latter as a more valid index of hunger (2). In recent psychological discourse, emphasis has shifted to the overt or behavioral manifestations of hunger, i.e., it is operationally defined in terms of the instrumental act of approaching food or the consummatory response of food ingestion (cf. 1, 4, 7). The experiment reported here was designed to examine the hormone hypothesis within the context of such a behavioral definition of hunger. Our methodology paralleled that of Luckhardt and Carlson. We injected animals with blood drawn from surfeited donors and we injected animals with blood drawn from hungry (food-deprived) donors. To anticipate our results, the subsequent food intake of the two recipient groups was found to be strikingly identical in amount. METHOD
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
