Relationship between career maturity and self-concepts of suburban and urban middle- and urban lower-class preadolescent black males

The relationship between career maturity and self-concepts of 252 sixth-grade black males was investigated. Student samples of suburban and urban middle- and urban lower-class were drawn from 42 different school settings located in Monroe, Erie, and Westchester Counties of New York State. The Attitude Scale of the Career Maturity Inventory and the Coopersmith Self-Esteem Inventory were used to assess the association of career maturity and self-concepts. Results indicated relatively weak-positive relationships between career maturity and self-concepts. Significant career maturity differences were found. However, self-concepts of the three groups were not statistically significantly different. Of the set of independent variables predicting and estimating variance accounted for (socioeconomic status, family intactness, place of residence, and reading), socioeconomic status was found to have the strongest predictive value on career maturity. It was suggested that researchers examine elementary school black students' career development in view of the group with whom they identify most.     

Texture gradient effectiveness in the perception of surface slant

To assess the development of monocular slant perception as well as the relative effectiveness of different sources of information, children in first, third, and fifth grades and college adults were asked to make judgments of surface slant on the basis of monocular texture gradient information. Accuracy of judgment increased with increasing age. In addition, differences in gradient effectiveness were found. Compression gradients were relatively ineffective sources of information, whereas perspective and multiple gradients resulted in greater accuracy. The results suggest limitations on the specificity of certain forms of gradients.     

INCREASING EXTENDED CARE FACILITY RESIDENTS' ATTENDANCE AT RECREATIONAL ACTIVITIES WITH CONVENIENT LOCATIONS AND PERSONAL INVITATIONS1

Residents of extended care facilities generally exhibit a low level of attendance at recreational and therapeutic activities. Spatial arrangement of rooms, prompting, snacks, and small prizes have been suggested as factors that affect attendance. The present study examined the effects of an extensive system of prompts and the location of activity areas on the attendance of residents at a variety of activities. Twenty-six subjects were randomly selected from the ambulatory population of the facility. The first time each subject entered the activity room during the first 6 min of an activity session their name was recorded. Reliability measures were taken at 10 sessions, with a 95% mean agreement between observers. The variables examined were the amount of individualization of subjects (experimental group I: names announced versus experimental group 2: names not announced), room location (central or peripheral), use of names in announcements (activity only versus activity and group I names), and mode of announcement (PA system only versus PA system and in-person). A counter-balanced group design with repeated measures was used, with a randomly determined order of application of experimental treatments. An analysis of variance split plot 2.222 (Kirk, R. E. Experimental Design: Procedures for the Behavioral Science. Belmont, Ca.: Brooks-Cole, 1968.) of the level of subject attendance yielded significant main effects for room location, F(1, 24) = 5.47, p < 0.05, and type of announcement, F(1, 24) = 9.10, p < 0.01, and significant interactions for Individualization × Use of Names in Announcements, F(1, 24) = 5.57, p < 0.05, and Room Location × Mode of Announcement, F(1, 24) = 7.90, p < 0.01. The results indicate that using a centrally located room and announcement of resident names increases attendance at a variety of activities. The increased social and environmental interaction generated by activity attendance has potential therapeutic benefits for the residents involved. Furthermore, the kind of information reported here and by others should be taken into consideration by planners of a variety of group living facilities, ranging from nursing homes to residential treatment cottages.     

ACCURACY OF SELF-ASSESSMENT OF ON-TASK BEHAVIOR BY ELEMENTARY SCHOOL CHILDREN1

Being able to assess one's own performance would seem to be prerequisite to most forms of self-management. The present study investigated the extent to which children in a typical second-grade classroom could accurately assess their own academic on-task behavior. In essence, this investigation replicated an experiment by Glynn and Thomas (Journal of Applied Behavior Analysis, 1974, 7 , 299–306) and extended those findings, by studying self-assessment over a longer span of time. The 31 children in the class ranged in age from 7 yr five months to 8 yr six months. Although only eight “problem” children were observed and studied, the self-control treatment procedures were applied to all children in the class. Behavior was observed daily during mathematics lessons for over eight school weeks. The study utilized a five-phase ABABC design, where the A phases were baseline periods, B phases were self-control periods, and C phase was a postcheck. In the self-control phases, children were asked by the teacher to put a check on their own individual performance card if they were on-task when a signal sounded. If they were not on-task, they were instructed not to touch their card. Typically, 15 to 20 signals occurred per 40-min session. At the end of the lesson, children were allowed to choose games to play according to how many checks they had earned. During all experimental phases, observers measured children's on-task behavior. Other observers measured the children's accuracy of self-assessment in the self-control phases. The results showed noticeable increases in the daily mean on-task behavior scores in the self-control phases following baseline phases. Also, a high level of on-task behavior was maintained in the postcheck phase. The variances of on-task behavior scores during the self-control phases were noticeably smaller than those in the baseline phases. Generally, individual data reflected group results, with some minor differences. Levels of accuracy of self-assessment varied from very accurate (95% of the time) to relatively inaccurate (56% of the time). The overall level of accuracy for all children was 78%. No consistent individual pattern appeared across phases. Some children got better as the study proceeded and some got worse. Most subjects tended to give themselves too much reinforcement, rather than too little. Peer social surveillance appeared to be the major factor that influenced individuals' evaluation of their own behavior, even though the teacher did make some control remarks in regard to how the children marked their cards. The results also demonstrated that self-control techniques can increase on-task behavior in a classroom with no history of external reinforcement, and that these techniques can have a lasting effect for more than two months of a school year.     

MODIFICATION OF THE EXCESSIVE INAPPROPRIATE CLASSROOM BEHAVIOR OF TWO ELEMENTARY SCHOOL STUDENTS USING HOME-BASED CONSEQUENCES AND DAILY REPORT-CARD PROCEDURES1

Two experiments investigated home-based reinforcement contingencies to control excessive behavior in normal classrooms. Subjects were, respectively, a 12-yr-old fifth-grade boy and a 9-yr-old fourth-grade boy, each in a separate classroom and with a different teacher. Following baseline observations in which observers recorded several categories of student behavior and teacher-student interaction, separate conferences were held including parents of the two children, the principal, teachers, and experimenters. A daily report-card procedure was agreed on, stipulating a one-day suspension from school following three successive “undesirable” daily report cards as well as the supervision of home-based privileges and other reinforcers usually contingent on satisfactory daily reports. Measurements of daily rates of teacher attention indicated no important change in this variable throughout the various experimental conditions. The daily report procedure significantly reduced disruptive classroom behavior. In a second experiment, a teacher-operated timer cued her own time-sample observations. Reliability measures revealed that the teacher could accurately measure the child's behavior while she was teaching the class. The procedure was ultimately successfully expanded to the teacher's total contact hours each day.     

Latent roots of random data correlation matrices with squared multiple correlations on the diagonal: A monte carlo study

In order to make the parallel analysis criterion for determining the number of factors easy to use, regression equations for predicting the logarithms of the latent roots of random correlation matrices, with squared multiple correlations on the diagonal, are presented. The correlation matrices were derived from distributions of normally distributed random numbers. The independent variables are log (N–1) and log {[n(n–1)/2]–[(i–1)n]}, whereN is the number of observations;n, the number of variables; andi, the ordinal position of the eigenvalue. The results were excellent, with multiple correlation coefficients ranging from .9948 to .9992.This research was supported by the Office of Naval Research under Contract N00014-67-A-0305-0012, Lloyd G.
