The role of familiarity in determining typicality

Ashcraft (1978b) found that people tend to know more properties of instances they rate as typical of a category than of instances they rate as atypical. This suggests that variations in typicality result from variations in familiarity. Three experiments are presented that challenge or qualify this suggestion. Experiment 1 showed that subjects sometimes produce more properties for items they rate as low in typicality. Experiment 2 showed that in a large, random sample of items, there was a tendency to produce fewer properties for atypical items, but Experiment 3 indicated that part of the reason for this result was a response bias to assign low typicality ratings to unfamiliar words, rather than a reflection of low perceived typicality of the referents themselves. These results suggest that variations in typicality can exist independent of variations in familiarity, although familiarity may also play a role.     

Irrational beliefs as predictors of negative affective states

One effort to specify cognitive mediators related to dysfunctional emotional responses has been made by Ellis, who proposed that certain irrational beliefs elicit maladaptive emotional reactions. In order to test Ellis's hypotheses in a nonclinical sample, the Irrational Beliefs Test, two anxiety inventories, the MMPI-168, and a locus of control scale were completed by 32 male heavy social drinker undergraduates, who then kept daily records of their anxiety, anger, unhappiness, and drinking behaviors for 7 months. Four factors underlay the 10 beliefs but did not necessarily correlate with dysphoric affect. Certain irrational beliefs predicted daily unhappiness ratings over the 7-month period and daily anger ratings over 3 months, but the beliefs exhibited only a weak relationship with daily general anxiety ratings. Irrational beliefs, especially worrying about approval and competence, were strongly related to test anxiety and Spielberger's trait anxiety measure, were somewhat related to social anxiety and general anxiety, were minimally related to locus of control and social desirability, and were essentially unrelated to the MMPI-168's measures of depression and anxiety and to drinking behaviors. Although 2 of the irrational beliefs failed to exhibit relationships with negative affect, the other 8 show the predicted relationships to moods, providing support for a cognitive mediational model of maladaptive emotions in a nonpathological population.This research was partially supported by grants from the Alcoholism and Drug Abuse Institute, University of Washington, Seattle, from a National Institute of Mental Health small grant AA03947-01, and from a National Institute of Alcohol Abuse and Alcoholism postdoctoral training fellowship No. 1T32AA07171-01.

Sources of organizational power for women: Overcoming structural obstacles

The ability of women (and men) to achieve success within organizational settings depends on their understanding structural and behavioral dimensions of power. However, the increased emphasis on educating women in the behavioral methods (e.g., assertiveness, aspirations, politics) of acquiring power invariably minimizes or omits the potential contribution of structural considerations. In their journey toward power acquisition, women must recognize and utilize the wide array of structural paths available to them. An analysis is undertaken of the main structural (organizational) sources of power — centrality, coping with uncertainty, and control over resources — with emphasis on their ramifications for women.The research cited in this article includes empirically based studies as well as observations, assertions, or admonitions that have not received extensive empirical validation. Nonetheless, the latter personal experiences and observations of these authorities may be valid.Management Analysis Company     

Toward understanding sex differences in pay allocation: Agency,communion, and reward distribution behavior

This research examined the extent to which the personality characteristics of agency and communion are sex linked, and the extent to which differences in these orientations can account for sex differences in reward distribution behavior. In two studies, the agency and communion level of large samples of male and female undergraduates were assessed. As expected, males were more agentic and females were more communal. Moreover, when subjects who scored high or low on agency and high or low on communion were asked to allocate rewards between themselves and a co-worker, these personality differences were related to their allocation decisions. These results were used as the basis for discussing the role that sex-linked personality differences might play in distributive justice judgments.This article is an adaptation of a colloquium presentation at the meeting of the American Psychological Association, Los Angeles, August 1981.

Four experiments examined the effects of noise on semantic memory. The first was a replication of a study by Eysenck, in which subjects had to retrieve words beginning with particular letters which were also instances of specified categories (e.g. Fruit-A). Whereas Eysenck had found that both noise and activation level of the individual interacted with the dominance of the category instance possible, the present study failed to repeat the findings.The remaining experiments used a paper-and-pencil modification of Eysenck's technique; the second and third were successful in showing interactions of dominance and noise, but in opposite directions. The two experiments differed only in the previous experience of the subjects. In a fourth experiment, the same materials were presented in a different sequence, mixing dominant and non-dominant instances. The interaction then disappeared again.These experiments therefore suggest that the effect of noise on memory is not a uniform and mechanical exaggeration of dominance, but depends on the retrieval strategies being employed by the particular subject.     

Increasing participation and improving the quality of discussions in seventh-grade social studies classes

An experiment was conducted to evaluate procedures to improve classroom discussions in seventh-grade social studies classes. An increased number of students participated in discussions when rules were stated for discussions, students were praised for their contributions, the teacher restated or paraphrased students' contributions aloud or on the blackboard, the teacher planned an outline of discussion questions, student contributions to discussions were recorded and were used to determine part of the students' grades for the class, and discussion grades were publicly posted.The second part of the study focused on procedures designed to improve quality of classroom discussions. Students were taught to participate in discussions by providing reasons for their statements, comparisons between different points, or examples supporting their statements. As each type of contribution was taught, recorded, and counted toward part of the students' classroom grades, each type of contribution increased. Ratings of discussions by outside judges consisting of junior high school teachers, junior high school students, and persons experienced in conducting discussions, indicated that the training increased the overall quality of the discussions. Use of the quality training procedures, however, resulted in decreased levels of overall participation in discussion, a decrease that was reversed by the use of a group contingency for participation. Finally, the discussions after training seemed to be preferred by both the teacher and the students.     

Metalinguistic awareness and language development

Thirty-six 3- and 4-year-old children were given a battery of six metalinguistic tasks and two measures of language development: the Peabody Picture Vocabulary Test and a sentence comprehension test. The results clearly showed that the majority of preschoolers were able to make at least some metalinguistic judgments, and that metalinguistic performance improved with age. Furthermore, overall performance on the metalinguistic tasks was significantly correlated with each language measure when the effects of age were partialed out. In contrast, the correlation between age and metalinguistic performance was not significant once the effects of both language measures were partialed out. These data demonstrate that preschoolers' metalinguistic abilities are more extensive than has been previously acknowledged, and that they are closely tied to other aspects of language development at this time.     

Recognition models evaluated: A commentary on Keren and Baggen

In a recent paper (1981), Keren and Baggen proposed two new models for alphanumeric confusion data, based on Tversky’s (1977) feature model of similarity, and compared them with Luce’s (1963) biased choice model. On the basis of their data, they concluded that, although the choice model fit slightly better, their models were to be preferred on grounds of parsimony and interpretability. It is shown here that both of these models are special cases of the Luce model, so that the general Luce model will necessarily fit better. This leads to considerable reinterpretation of Keren and Baggen’s conclusions. Finally, better methods of estimating parameters and evaluating goodness-of-fit are suggested, taking advantage of this relation between the models.
