AN EXPERIMENTAL COMPARISON OF A CONTINGENCY MANAGED COURSE WITH LARGE LECTURE METHOD1

Contingency management procedures resembling the Personalized System of Instruction (PSI) were compared with a conventional lecture method in teaching an introductory psychology course. The use of a within-subjects design in which half of the students experienced both teaching conditions made it possible to examine the reliability of test-score differences over time when subjects were balanced over conditions. In the contingency management course, material was broken down into 14 small units, each unit covering about 30 pages of text. Students were assigned to an undergraduate teaching assistant who was encouraged to develop a close working relationship with each of his/her 13 assigned students. Specifically, this meant that the assistant was to call each student by his/her first name, show an interest in the student's quiz performance, help the student understand difficult concepts, and discuss various topics of interest to the student. Each week, the teaching assistant administered up to four different 10-item multiple-choice quizzes over the week's chapter. A modified “Doomsday Contingency” required each student either to achieve a score of 80% on one of the four quizzes or drop the course. Most students passed the quiz during the first session of the week; those not passing were tutored on special areas of weakness. No student was actually forced to leave the course under the Doomsday Contingency. Although quizzes were administered on a group basis, they were scored individually while the student stood near by. In addition to the weekly quiz assignment, students under the contingency management procedures were asked to attend one lecture per week. The contingency management method departed from traditional PSI in that (1) self pacing was minimal, such that students were required to master one unit per week or drop the course, (2) teaching assistants met with students in small groups, and usually gave individual tutoring only to those students who did not pass the quiz on the first attempt, and (3) students were asked to attend one lecture per week. However, it was similar to PSI in that small units of subject matter were assigned and unit mastery was assessed through use of undergraduate assistants who delivered immediate feedback. Students in the conventional lecture group attended three 50-min lectures each week; two of these lectures followed textbook material closely, while the third, which was attended by all students, concerned material only indirectly related to the text. As a result, students in both conditions were exposed to essentially identical material. Students in the lecture condition could also obtain copies of the unit quizzes, although few did so. Course grades were determined by scores on two 45-item multiple-choice hourly exams, each covering half of the semester material (each worth 25%), and by a 90-item final exam over the entire course (worth 50%). These measures also served as the dependent variables. The experimental design employed a crossover technique in which one fourth of the students began with the contingency management method and then switched to lecture method at midsemester, while another fourth began with the lecture method and switched to contingency management. The other students stayed in the same condition throughout the semester, half under contingency management and half under the lecture method. On the last day of class, all students filled out an extensive questionnaire that assessed their opinions and attitudes about the teaching techniques. In addition to allowing for assessment of any progressive effects that the contingency management procedures might have had over time, the crossover design also permitted students to make meaningful comparisons of the two teaching methods, since half of the students experienced both methods in the same course. Although average test performance was only slightly higher under the contingency management condition, this difference occurred on each exam and was statistically reliable in each case. Further, the method did not interact with time, as it produced about a three-item advantage per half semester. On each of the three exams, teaching method accounted for between 5 and 8% of the total variance in test scores. Finally, attitude measures indicated that students experiencing half a semester of the contingency management procedures preferred them to the lecture technique, but that only those students with a full semester of contingency management rated the course significantly better than students in the full semester lecture course.     

Sex differences in preadolescent self-disclosure

Both amount and content of self-disclosure may vary with sex role. Both adult and preadolescent females have been reported as engaging in greater amounts of self-disclosure than males; the present study attempted to replicate these findings with preadolescents, and to investigate sex differences in the content of self-disclosure. A self-disclosure questionnaire covering a wide range of subjects was administered to 307 urban children. The sex difference on the total number of items revealed to a friend closely approached significance, with girls showing greater disclosure. When only intimate content items were examined, the sex difference reached clear significance. Content analysis showed that girls were more willing to reveal items related to emotionality, anxiety, and dependence.     

Handedness and sex differences in hemispheric asymmetry

A study was designed to assess the contributions of the factors of sex and familial history to cerebral dominance, where cerebral dominance was inferred from laterality on a dichotic listening task. The 144 subjects were selected from a larger sample on the basis of handedness, sex, and familial history of sinistrality, and tested on a task involving the dichotic presentation of CV syllables. Analysis of the data indicated that in female subjects, the presence of familial sinistrality increased the likelihood that they present atypical left-ear superiorities, while in males the converse was the case. Moreover, there was a significant sex difference overall, such that males were more clearly lateralized than females. A review of other dichotic listening studies provided support for the reliability of this sex difference for dichotic tasks using verbal material. A review of the clinical literature indicated that the hypothesis of a sex difference is at least tenable and merits further investigation. However, the possibility that there is a sex difference in the cognitive strategy used in dichotic listening cannot be ruled out.     

Comorbidity of test anxiety and other anxiety disorders in children

Elementary school children with clinically significant test anxiety, as determined by self-report and a clinical interview, were assessed for the incidence of other fears and anxiety. The results indicated that test-anxious children reported more fears and general worries than their non-test-anxious peers. As expected, the test-anxious children experienced more negative cognitions and subjective distress when taking a test. Furthermore, the fear of negative evaluation was not limited to an actual test, since these children also reported identical symptoms when engaged in a second social-evaluative task. Finally, 60% of the testanxious sample met DSM-III criteria for an anxiety disorder. The results are discussed in terms of the relationship of text anxiety to more complex social-evaluative dysfunctions, more pervasive anxiety conditions, DSM-III anxiety disorders, and the utility of test anxiety as an indicator of the presence of these more pervasive anxiety states.This research is based on a dissertation conducted by the first author under the direction of the second author.

Cross-domain semantic priming in normal subjects and a prosopagnosic patient

Cross-domain semantic priming of person recognition (from face primes to name targets at 500msecs SOA) is investigated in normal subjects and a brain-injured patient (PH) with a very severe impairment of overt face recognition ability. Experiment 1 demonstrates equivalent semantic priming effects for normal subjects from face primes to name targets (cross-domain priming) and from name primes to name targets (within-domain priming). Experiment 2 demonstrates cross-domain semantic priming effects from face primes that PH cannot recognize overtly. Experiment 3 shows that cross-domain semantic priming effects can be found for normal subjects when target names are repeated across all conditions. This (repeated targets) method is then used in Experiment 4 to establish that PH shows equivalent semantic priming to normal subjects from face primes which he is very poor at identifying overtly and from name primes which he can identify overtly. These findings demonstrate that automatic aspects of face recognition can remain intact even when all sense of overt recognition has been lost.     

Reconsidering the Role of Attitudes in Exercise Behavior: A Decision Theoretic Approach1

Two studies demonstrated that subjective expected utility (SEU) theory predicted interest in, but not adherence to, a weightlifting exercise program. The studies also showed that attitudes were related to adherence for certain individuals. Specifically, attitudes toward not weightlifting were related to the number of days experienced subjects weightlifted. In addition, in Study 1, experienced subjects had more positive attitudes toward weightlifting and more negative attitudes toward not weightlifting than did inexperienced subjects, and the two groups differed on a number of underlying beliefs. Similarly, in Study 2, experienced subjects had more positive attitudes toward weightlifting and differed from inexperienced subjects on a number of underlying beliefs. These results are discussed in terms of their implications for several issues: the usefulness of SEU theory in the exercise domain; the importance of considering attitudes toward alternative courses of action (including inaction) when attempting to predict exercis–or any other–behavior; the need to distinguish between exercise adoption (initiation) and maintenance (adherence); and the importance of Beach's (1982, 1985) distinction between deasion making and decision implementation.     

Self psychology and group therapy

This paper illustrates how the theories of Heinz Kohut elucidate the curative aspects of group treatment. Group therapy is an ideal milieu in which mirroring, idealizing and alterego transferences can be experienced and worked through. Transmuting internalizations, or psychic structure building, occur when optimal frustration of these needs can be provided by available selfobjects. In group therapy a patient can use the group-as-a-whole, the individual members as well as the leader as potential selfobjects. With the help of individual sessions to reflect on group encounters, a patient can gain a more fully integrated therapeutic experience.The author wishes to acknowledge Susan Sands, Ph.D., Jane Jordan, M.S.W., and Ruth White, Ph.D., for their help.     

The three bears are all boys: Mothers' gender labeling of neutral picture book characters

Two studies examined mother's labeling of gender-neutral characters in young children's picture books. In the first study, mothers and their 18- to 38-month-old children looked at three popular children's books together. The mothers' use of masculine or feminine names or pronouns to refer to gender-neutral characters was recorded. The data revealed an extreme masculine bias: 95% of all characters of indeterminate gender were referred to by the mothers as males. In a second study, specially prepared picture books were used to examine the effect of gender-relevant variables on the mothers' labeling. The results replicated Study 1 in showing a strong bias toward referring to neutral pictures with masculine labels: The incidence of masculine labels was again high and, in addition, was relatively impervious to most of the gender-relevant manipulations included in the books. The one variable that had a strong, consistent effect on the mothers' labeling was the presence of an adult in the pictures: Child Characters were nearly always referred to as males when they appeared alone; they were more likely to be given feminine or neutral lables when they were pictured in the presence of an adult. This result is related to Carpenter's [Activity Structure and Play: Implications for Socialization, in M. Liss (Ed.), Social and Cognitive Skills: Sex Roles and Childrens Play, New York: Academic Press, 1983] model of the development of sex-typed behavior. The data are also discussed with respect to the well-documented sexist bias in picture books for preschool children.This research was support in part by Grants HD-05951 from NICHHD and R01 MH33082-01 from NIMH to the first and third authors, respectively.

Computerphobia

Five studies of over 450 university students presented a comprehensive picture of computer-phobia. Three research and clinically based self-report instruments were developed to measure three nearly independent dimensions of computerphobia-computer anxiety, computer attitudes, and computer cognitions and feelings. Results indicated that older students were more computer anxious, but did not have more negative attitudes, cognitions, or feelings, than did younger students. Women had more negative attitudes than did men. Feminine-identity students showed more anxiety and negative attitudes than did masculine-identity students, regardless of gender. White students had more anxiety and more positive attitudes than did nonwhite students. Computerphobia was related to other anxiety measures (mathematics, state, and trait), but was a separate construct. Experience with computer interaction did not reduce anxiety or improve attitudes. Finally, regardless of academic major, computer-anxious students showed less computer aptitude, literacy, and interest. Implications for treating computerphobia are discussed.
