Factor structure of the McCarthy scales for school-age children with low GCIs

This study aimed to cross-validate the factor analysis of the McCarthy Scales and to determine the construct validity of these scales for children who score one standard deviation below the normative mean on general cognitive ability. The sample was comprised of 77 children aged 6 to $\text{8}\text{1}\text{2}$ with a mean General Cognitive Index (GCI) of 61.6. Principal factor analysis produced four meaningful factors which corresponded closely to four of the scales on McCarthy's battery. The present findings discourage the interpretation of the Quantitative Scale for school-age children with GCIs below 84. Other implications of the results for the interpretation of McCarthy profiles for low-scoring school-aged children are discussed.

INSTRUCTIONS,FEEDBACK, PRAISE,BONUS PAYMENTS,AND TEACHER BEHAVIOR1

The study was conducted within a training and demonstration center for teachers from several different school districts. The teachers staffing the center were employees of the host school district who volunteered to serve in the center. Unfortunately, these volunteers did not always use the program materials appropriately and therefore did not always provide clear models for visiting teachers. In particular, four of the volunteer teachers did not always instruct their students from the appropriate reading text, even when encouraged to do so by the principal of the school in which the center was located. Various procedures were employed to alter this situation. The experimenter, (associate director of the training and demonstration center) provided instructions, feedback, and praise regarding use of the appropriate reading text. These procedures had clear effects with only one teacher. Then, merit or bonus payments were provided for teachers who used the appropriate reading text for criterion periods of time; a procedure that was very effective with all four teachers. The problem worked on in this study is typical of those faced by workers in public institutions where change cannot be brought about by the researcher's authority. All teachers in the present study had the necessary skills to demonstrate accurately the prescribed program procedures, but they did not always do so until the bonus payment was used. Although the bonus payment procedure might be inappropriate in some school situations, the procedure could easily be adjusted to accommodate the established practices of many schools. For example, establishment of explicit performance criterion and use of in-service stipends for meeting criterion performance during school hours, rather than attendance at meetings after school, might well be comparably effective.     

An attitude profile for studies of population psychology

Attitudes toward specific issues in population covary, but are independent enough to warrant separate assessment. Identifiable components include family planning, abortion, contraception, and population management. Modernity may be defined as a norm-setting factor, establishing a baseline around which the four other dimensions may vary. A system of beliefs will be more or less in phase or out of phase depending on the congruence between modernity and the other four indices. Scales to assess each factor were developed, and an attempt was made to minimize unwanted or artifactual variance pertaining to generalized distrust or misanthropy. Five case vignettes were given to illustrate the personological implications of contrasting profile configurations.     

Signal/noise ratios for domain-referenced tests

Using the assumption of randomly parallel tests and concepts from generalizability theory, three signal/noise ratios for domain-referenced tests are developed, discussed, and compared. The three ratios have the same noise but different signals depending upon the kind of decision to be made as a result of measurement. It is also shown that these ratios incorporate a definition of noise or error which is different from the classical definition of noise typically used to characterize norm-referenced tests. Part of the work leading to this paper was accomplished while the authors were assistant professors at the State University of New York at Stony Brook.     

THE PAINS OF R-GEORGE,ROBOT

In this essay I wish to raise the question of whether it is meaningful to say that a certain sort of robot is in pain. This is, of course, not an empirical question. There exists no robot of the sort I shall describe. But, I shall argue, if such a robot did in fact exist, it would be meaningful to say it is in pain.     

The female athletic role as a status determinant within the social systems of high school adolescents

This study examined the relationship between female athletic participation and status attainment within the social status systems of high school adolescents. Although earlier research has consistently demonstrated that the athletic role for males is associated with greatest status within the school, findings regarding the status of female athletes have been contradictory: Some studies have found high status rankings for female athletes while others have revealed negative results. It was therefore argued that current research go beyond the general construct of "female athlete" and consider the type of sport with which the adolescent female is associated as a possible status determinant. Employing a sport typology proposed by Metheny (1967), it was predicted that females associated with sex-appropriate or "feminine" sports (e.g., tennis) would receive significantly higher status ratings than those identified with sex-inappropriate or "masculine" sports (e.g., basketball). One hundred and twenty-one male subjects were asked to indicate which female athlete (associated with a sex-appropriate versus a sex-inappropriate sport) they would most like to date, while 111 female subjects were asked to choose which female athlete they would most like to have as a friend. Chi-square analyses revealed that, as predicted, females associated with sex-appropriate sports were given significantly greater status than females identified with sex-inappropriate sports by both male and female subjects. These results suggest that social assessments made about female sport participation within high school status systems remain heavily influenced by traditional beliefs regarding feminine, "ladylike" behavior.     

Stevens' power law and time perception: effect of filled intervals, duration of the standard, and number of presentations of the standard

Subjects estimated the duration of five different time intervals, either filled or unfilled, in relation to one or two standard intervals. Half of the subjects were presented with the standard at the beginning of the experiment only, and half were presented with the standard before every interval. The five estimations were then used to calculate, for each subject, the exponent in Stevens' Power Law which describes the form of the power relationship. The resulting over-all exponent of .91, although nearly linear, was significantly different from 1.0. The data were then analyzed by a 2 X 2 X 2 analysis of variance which showed a significant interaction between presenting the standard either once or before each interval with the duration of the standard.
