Identifying distinctive groups in a college applicant pool

In a time when most post-secondary educational institutions must distribute limited resources more efficiently, segmentation analysis affords a way to direct planning to yield strategic benefits. The Automatic Interaction Detector is recommended to the institutional research community as an analytical tool for effectively identifying distinctive subgroups within an educational market. In this application, AID is used to segment the Boston College applicant pool according to subgroups' relative probabilities of enrolling. The findings illustrate that AID can make a useful contribution to market research and that the technique has broader applicability—to other student groups and to other educational policy questions.An earlier version of this paper was presented at the Twenty-First Annual Forum of the Association for Institutional Research, Minneapolis, May 1981.     

Children's memories for painful cancer treatment procedures: implications for distress

Children (ages 3 to 18, N = 55) diagnosed with leukemia were tested for their memories of lumbar punctures (LPs), a repeated and painful part of the cancer treatment protocol. Memory for both event details and the child's emotional responses was assessed one week after the LP. Children of all ages displayed considerable accuracy for event details, and accuracy increased with age. Overall recall accuracy for event details and emotional responses was similar. Recall among children given oral Versed was similar to that among children not given Versed. Finally, higher distress predicted greater exaggerations in negative memory 1 week later (although controlling for age weakened this relationship); moreover, greater exaggerations in negative memory predicted higher distress at a subsequent LP. These results indicate that children's memories play an important role in their experience of distress during repeated stressful events.     

A Combination of Vocal f0 Dynamic and Summary Features Discriminates between Three Pragmatic Categories of Infant-Directed Speech

To assess the relative contribution of dynamic and summary features of vocal fundamental frequency (f₀) to the statistical discrimination of pragmatic categories in infant-directed speech, 49 mothers were instructed to use their voice to get their 4-month-old baby's attention, show approval, and provide comfort. Vocal f₀ from 621 tokens was extracted using a Computerized Speech Laboratory and custom software. Dynamic features were measured with convergent methods (visual judgment and quantitative modeling of f₀ contour shape). Summary features were f₀ mean, standard deviation, and duration. Dynamic and summary features both individually and in combination statistically discriminated between each of the pragmatic categories. Classification rates were 69% and 62% in initial and cross-validation DFAs, respectively.

Power imbalance and anticipation of conflict resolution: Positive and negative attributes of perceptual recall

This study investigated the impact of power imbalance on the relationship between perceived communication behaviors and the anticipation of conflict resolution. The subjects were 120 students who responded to a survey questionnaire in which they evaluated a conflict in which they were engaged. They were divided into three groups (high power, low power, equal power) based upon their responses to the survey. Correlational analysis indicated that when the participants in the conflict were of equal power, anticipated resolution was related to perceptions of both solution‐oriented and control behavior. However, in cases of power imbalance, solution‐oriented behavior was the only significant cue identified, and it was used by both low‐and high‐power participants.
