The Measurement of Verbal Working Memory Capacity and Its Relation to Reading Comprehension

Ninety-four subjects were tested on the Daneman and Carpenter (1980) reading span task, four versions of a related sentence span task in which reaction times and accuracy on sentence processing were measured along with sentence-final word recall, two number generation tasks designed to test working memory, digit span, and two shape-generation tasks designed to measure visual-spatial working memory. Forty-four subjects were retested on a subset of these measures at a 3-month interval. All subjects were tested on standard vocabulary and reading tests. Correlational analyses showed better internal consistency and test-retest reliability of the sentence span tasks than of the Daneman-Carpenter reading span task. Factor analysis showed no factor that could be related to a central verbal working memory; rotated factors suggested groupings of tests into factors that correspond to digitrelated tasks, spatial tasks, sentence processing in sentence span tasks, and recall in sentence span tasks. Correlational analyses and regression analyses showed that the sentence processing component of the sentence span tasks was the best predictor of performance on the reading test, with a small independent contribution of the recall component. The results suggest that sentence span tasks are unreliable unless measurements are made of both their sentence processing and recall components, and that the predictive value of these tasks for reading comprehension abilities lies in the overlap of operations rather than in limitations in verbal working memory that apply to both.     

SOCIAL INFLUENCE STRATEGIES AMONG JAPANESE AND AMERICAN COLLEGE WOMEN

Social influence strategies of 40 Japanese and 41 American college women were compared. With the use of a free-response format, respondents were asked to describe how they get their way with their mother, father, male teacher/boss, female teacher/boss, male friends, and female friends. Contrary to expectations, content analysis indicated that Japanese women reported using strong and neutral strategies more frequently and weak strategies less freguently than American women. American women used manipulation (especially sexual manipulation) more frequently and reasoning less frequently than Japanese women. Analyses by target of influence indicated that these differences were not found when the target was a female friend but were demonstrated across most of the other targets.     

CODEPENDENCY, LOSS OF SELF, AND POWER

The feminist critique that codependency and loss of self are related to power was tested in a sample of 122 college women and men in committed relationships. Participants completed two codependency measures, a loss of self scale, and three indices of power: perceived power, use of specific influence strategies, and decision making. Among both women and men, codependency and loss of self were positively related to the use of indirect strategies and negatively related to perceived power, and loss of self was negatively related to use of the direct strategies. Among women alone, codependency was also negatively related to use of direct strategies and loss of self negatively related to decision making. These correlational data provide support for a feminist critique of codependency as related to power; however, gender similarities suggest that the relations between power, loss of self, and codependency hold for college men as well as college women.
