Software for advanced ANOVA courses: A survey

In response to a survey of faculty regarding their commercial software preferences for advanced analysis of variance courses, it was found that the most frequently used packages were SAS, SPSS^x, and BMDP, all originally mainframe packages. The fourth choice, SYSTAT, was written for microcomputers but is currently also available for other host computers. Difficulty for students was the most frequently cited reason fornot using one of these four packages. The most important criteria for choosing software packages were variety of designs, accuracy, and ease of use. Cost was a factor only for microcomputer licenses. Packages using the general linear model approach were paramount to some, while others would not consider such packages. Instructors decried the lack of the “ideal program,” but the diversity of their desires makes it clear that no program could be ideal for all of them. Many faculty seemed unaware of newer software packages or of the extent to which older packages (particularly Minitab) have been modified; some had their choices constrained by departmental limitations. Better dissemination of information about statistical software is needed, whether it be from software publishers or through the professional literature.     

INCREASING HABILITATIVE SERVICES FOR PERSONS WITH PROFOUND HANDICAPS: AN APPLICATION OF STRUCTURAL ANALYSIS TO STAFF MANAGEMENT

We evaluated a structural analysis methodology for enhancing the utility of a staff management program. In Experiment 1, a structural analysis of direct-care staff behavior in a mental retardation facility revealed differences in work patterns over time. Specific times were identified when few basic care duties were necessary and staff engaged in nonwork activity. In Experiment 2, a management program was implemented to increase staff members' training activities during periods identified through the structural analysis. The program was accompanied by increases in training activities and decreases in nonwork behavior. The improvements were maintained during a 43-week period while the most labor-intensive component of the program was withdrawn. Staff acceptability measures indicated a positive response to the management intervention, although responses varied across components within the multifaceted program. The increased training was accompanied by beneficial changes among clients with profound handicaps. Results are discussed regarding practical considerations for improving staff performance and for adopting innovations resulting from applied research.     

SIGNS AS DETERRENTS OF ILLEGAL PARKING IN SPACES DESIGNATED FOR INDIVIDUALS WITH PHYSICAL DISABILITIES

The percentage of illegal parking in spaces reserved for the physically disabled was monitored under three sign conditions: ground markings, ground markings plus vertical signs, and vertical signs containing a message that concerned citizens were watching the spaces. Illegal parking dropped from 69.3% of 102 vehicles during the initial ground-sign condition to 57.3% of 36 vehicles in the first vertical-sign condition. Following removal of the vertical signs, illegal parking increased to 68.7% of 43 vehicles. During the second vertical-sign condition, illegal parking dropped to 53.7% of 32 vehicles, followed by an increase to 69.5% of 68 vehicles after the vertical signs were removed. The lowest rate of illegal parking (27.1% of 78 vehicles) occurred in the vertical-sign-plus-message condition. Illegal parking subsequently increased to 34.6% (of 94 vehicles) when the message sign was removed, followed by an increase to 65.2% (of 105 vehicles) when the vertical signs were removed.     

Generating makes words memorable,but so does effective reading

In many experiments, memorial benefits have been found when subjects generate items from fragments rather than read items in their complete forms. Does generation cause-this-difference, or are subjects disposed to adopt different strategies when generating as opposed to reading? If generating causes the difference, items processed in the same way apart from a generative stage should therefore benefit from that generative stage. Our experiments did result in benefits for generating as opposed to reading, but only when the readers processed the words poorly—by pronouncing them. When the readers processed the items well, by imagining them, generating was no better than reading. A new generation effect was found in meta memory. Subjects thought they would remember more generated items than read items; however, the act of making the prediction entailed meaningful processing, and the generated items were not actually remembered better than the read ones.     

Hard-to-manage preschool boys: Family context and the stability of externalizing behavior

Preschool boys identified by their teachers as active, inattentive, and impulsive (N=42) were compared with matched classroom controls (N=43) and with parentidentified problem boys (N=27) on measures of family functioning often associated with children's problem behaviors, including family history of psychopalhology, stressful life events, and family composition. Teacher-identified and parent-identified problem boys did not differ on measures of family adversity, and both groups came from less well functioning families than comparison boys. Mothers of problem boys, regardless of referral source, were more negative and controlling toward their sons when observed in a compliance task. Children's problem behaviors were moderately stable over a oneyear follow-up period; initial symptom levels, maternal self-reported depression, and negative maternal control predicted follow-up ratings of externalizing problems.Thanks are expressed to Clea Angell, Clare Flanagan, Julie Hunt, Patricia Huszar, Andrea Lurier, Sarah McAuliffe, Jasmine Sardessai, and Teri Sobolik for help with data collection, coding, and analysis. We are grateful to the staff of the many preschools in the Pittsburgh area who facilitated our work. Special appreciation is expressed to the children and parents who participated in this study.Portions of these data were presented at the Rochester Symposium on Developmental Psychopathology, Rochester, New York, October 1988, and at the Society for Research in Child and Adolescent Psychopathology, Costa Mesa, California, February, 1990. This work was supported by grant R0I MH32735 from the National Institute of Mental Health to Dr. Campbell.     

The Situational Facilitation of Interpersonal Attraction: A Three-factor Hypothesis1

A theoretical analysis of observations of natural and man-made disasters, festive social events, and task-oriented crash programs led to a three-factor hypothesis of attraction facilitation. It was proposed that interpersonal attraction toward strangers is facilitated when there is emotional arousal, sharing, and out-of-role behavior. In a laboratory investigation (N= 120), postexperimental attraction toward a dissimilar stranger increased when all three factors were present but not when only two of the three factors were present (p < .01). Consistent with the reinforcement-affect model of attraction, increased attraction toward the stranger in the three-factor conditions was paralleled by more positive feelings about the experiment in the three-factor than in the two-factor conditions. Knowledge of the variables underlying facilitation effects could be utilized on a societal basis to create attraction-enhancing occurrences.
