Prejudice against women: A new perspective

Studies 1 and 2 of this paper were designed to reexamine the assumption that women and men are prejudiced against women. Subjects were 50 college women, 40 college men, 40 high-school women and 40 high-school men who were presented with four employment applications for evaluation. The names referring to the gender of the applicants were manipulated so that half of the subjects were shown the two most qualified applicants as female and the two least qualified as male. The other half of the subjects were shown the reverse of this. The results for this factor, with women subjects, revealed that the sex of the applicants did not interfere with or distort the subject's judgments (p>.25). The men subjects did not show a preference for or a prejudice against applicants of either sex (p>.05). The qualifications of the applicants were selected according to each subject's previous ranking of 10 job-related characteristics. The results for this factor, with women subjects, indicated a significant difference between the subjects' ranking of the characteristics and their final selection of the applicants (p<.05). The men subjects showed no significant difference between the subjects' rankings of the job-related characteristics and their rating of the applicants (p>.05). No significant interaction between factors was found for either population of subjects (p>.05). This research reflects changing attitudes of women towards women and provides new insights regarding men's attitudes toward their own sex.The authors of this paper would like to extend our sincere gratitude to Dr. John Schaeuble for his continuous support of this research endeavor.     

A developmental and cross-cultural study of the influences of rule structure and problem composition on the learning of conceptual classifications

Five experiments were conducted permitting direct comparisons in the way Ss of different ages and cultures solved conceptual problems. One group of problems (Traditional) could be solved using a reference rule of conjunction or disjunction. Another group of problems (Intradimensional) could be solved either by one of the reference rules, or by a structurally simpler rule. Analysis of American performance confirmed that older Ss not only solved using the simpler rule more often than younger Ss, but when they did so they solved faster. For both American age groups, solution using the simpler rule led to no difference in performance between conjunctive and disjunctive Intradimensional problems. Conjunction proved easier than disjunction only for the Traditional problems. Unlike Americans, the Kpelle of Liberia did not solve using the simpler rule, and found conjunction easier than disjunction for both Traditional and Intradimensional problems. When a memory aid was provided the Kpelle showed a pattern of performance exactly like Americans.     

Power and speed components of individual differences in letter matching

Several previous studies have reported a correlation (typically around −.30) between standardized verbal ability test scores and name identity minus physical identity reaction times (NI-PI) in a letter-matching task. This correlation has usually been thought to reflect the mutual dependence of both measures on long-term memory access time. The present research was designed to assess Carroll's (1981) suggestions that: (a) NI — PI may not be the optimal formula for predicting standardized test scores from letter matching data, and (b) NI — PI may actually be related to the speed rather than the power component of standardized tests. Fifty-one subjects previously tested with a standardized reading test participated in letter-matching and word-reading tasks. The latter tasks required subjects to read words and specially constructed pseudowords. Power and speed measures were derived from the word-reading tasks and the standardized test on theoretical grounds (and supported by a principal components analysis). The results supported both of Carroll's contentions. NI — PI reaction time was related more to speed than power and the NI — PI statistic (as usually used) was not the optimum formula for predicting standardized test scores.     

Effects of parent enhancement therapy on the treatment outcome and generalization of a parent training program

The purpose of the present study was to examine the effectiveness of parent enhancement training in facilitating treatment and maintenance effects of a parent training program. Seventeen mothers and their clinic-referred noncompliant children were assigned to either a parent training alone group or a parent training plus parent enhancement therapy group. Fifteen mothers and their nonclinic children served as a quasi-control group. All clinic-referred mother-child dyads were treated individually by teaching the mother to reward compliance and other prosocial behavior and to use time-out for noncompliance. In addition, mothers in the parent training plus parent enhancement group also received treatment related to the following areas: parent's perception of their child's behavior, parent's personal adjustment, parent's marital adjustment, and parent's extrafamilial relationships. Assessment consisted of four home observations by independent observers prior to treatment, after treatment, and at a 2-month follow-up. The data indicated that the parent training plus parent enhancement therapy was more effective than parent training alone in changing child deviant behavior at posttreatment and in maintaining child compliance, child deviant behavior, parental rewards and parent contingent attention at follow-up. The control group did not change over the three assessment periods.     

The Importance of Context in the US Preexposure Effect in CTA: Novel versus Latently Inhibited Contextual Stimuli

Three experiments were conducted to examine the role of novel contextual stimuli in producing the unconditioned stimulus (US) preexposure effect. Experiment 1 demonstrated that novel contextual stimuli produce a significantly stronger US preexposure effect than familiar or “latently inhibited” contextual stimuli. Moreover, subjects preexposed in the presence of latently inhibited contextual cues failed to show a significant US preexposure effect. Experiments 2 and 3 attempted to provide evidence that the addition of a single novel stimulus to the latently inhibited context would result in a significantly stronger US preexposure effect than when no such novel cue was present. Experiment 3 was able to demonstrate this effect. Results are consistent with the Rescorla–Wagner (1972) model of conditioning.     

A review of functional assessment use in data-based intervention studies

We reviewed the extent and variety of functional assessment procedures used in behavioral intervention studies. The contents of six research journals dating from 1986 to 1992 were searched for articles describing single-subject intervention studies that targeted problematic social behaviors. Articles meeting this initial criteria were examined to determine if a functional assessment was conducted. If so, the various procedures comprising the functional assessment, types of interventions conducted, and demographic characteristics of study participants were recorded for each study. Results are compared to similar reviews of research dating from 1980–1985. Potential reasons for the paucity of studies incorporating functional assessment procedures are discussed. Finally, directions for future research and applied practice are provided.
