A Comparison of Distractors for Controlling Distress in Young Children During Medical Procedures

Distraction is a strategy that has been shown to be effective and safe in the control of pain and distress. We assessed the utility of two simple distraction procedures for reducing children's pain and distress. Three conditions, control, brief film, and short story, were delivered during repeated medical procedures in a randomized sequence to eight young children with cancer. Scores on the Observational Scale of Behavioral Distress (OSBD-R) as well as observer ratings of overall behavioral distress showed that the short story procedure was more effective than either the control condition or the cartoon film. These results argue for the utility of simple parent–child interactive distraction tasks to ameliorate children's procedural distress.     

The Role of General and Specific Psychomotor Tracking Ability in Validity

A study of 1,099 males and females in pilot training was conducted to investigate the relative importance of general and specific factors of psychomotor tracking ability in the prediction of several pilot training criteria. Measures of psychomotor tracking ability were derived from the Basic Attributes Test (Carretta and Ree 1994). The criteria were the dichotomous passing or failing pilot training and the average of six flying work samples. Comparisons of linear models indicated that general psychomotor tracking ability was the source of most of the validity and that only the specific measure of reaction time was incremental. Reaction time, although part of the psychomotor taxonomy, has frequently been identified as a measure of cognitive ability.

Critical incidents for psychology students in a refugee camp: Implications for counselling

Malawi is host to over one million refugees from the Mozambican war. Although there are no recognized positions for professional counsellors in Malawi, the need for counselling war affected refugees has been recognized. The experience of two psychology students who worked with war affected children is investigated, using the technique of Critical Incidents Analysis. Key characteristics of this work are identified as a means to creating a training curriculum to prepare students for future placement in refugee camps.     

Comparison of behaviors of suspected sexually abused and nonsexually abused preschool children using anatomical dolls

Using anatomical dolls, the play behaviors of nine sexually abused preschool children (five males, four females), ranging in age from 3 to 5 years, were compared with nine preschool children for whom there was no suspicion of sexual abuse and who were matched on the basis of age, gender, race, family status, and socioeconomic status. There was no significant difference between the two groups on explicit sexual behavior (vaginal, oral, and anal intercourse with thrusting motions between the dolls or between the child and the dolls and masturbation by the child). The groups were significantly [t(8)=2.19, p <.05; Wilcoxon W=6, p <.05) different when behaviors with suspicious sexual implication were combined with explicit sexual behaviors. There were no differences between the groups on measures of nonsexual behavior. The occurrence of the suspicious sexual behaviors is discussed and reviews of previous doll research and physical evidence of child sexual abuse are provided.This project was supported in part by a grant from The Graduate College of Western Michigan University, Kalamazoo, Michigan.     

Concerning the determination of trait variability

An analytic technique for the study of trait variability is presented. An expression for the average variance from test to test and an expression for the variance of these variances are derived in terms of the number of tests and the intercorrelations between them, and limiting cases are examined. The question of the true relationship between the nature of the distribution of test scores in a sample ofN persons and the nature of the distribution ofn traits in a single individual is discussed, and other problems are introduced.     

FIT: An iterative parameter-estimation function in LISP

A nested parameter-estimation program (FIT), written in LISP, is described. FIT searches an n-dimensional parameter space for the set of parameter values associated with either a minimum or a maximum criterion score. The range of the parameters is cut in half on each iteration. Two versions of FIT, one suitable for use on large, mainframe systems and the other designed for small microprocessors, appear in the appendices.     

Human spatial orientation in the pitch dimension

Two experiments were conducted. In Experiment I, each of eight Ss attempted to place himself at 13 different goal orientations between prone and supine. Deviations of achieved body pitch angles from goal orientations were determined. In Experiment II, each of eight Ss attempted to align a visual target with his morphological horizon while he was placed at each of the 13 goal orientations. Changes in settings of the target were examined. Results indicate that Ss underestimate body pitch when they are tilted less than 60 deg backward or forward from the vertical, overestimate body pitch when they are nearly prone, and accurately estimate body pitch when they are nearly supine. In contrast, Ss set the visual target maximally above the morphological horizon when they are tilted 30 deg forward from the vertical. The findings are discussed in terms of common and different physiological mechanisms that may underlie judgments of these types.     

Directional information and apparent movement

The number of alternative directions that a point of light can take in the apparent movement produced by the successive exposure of two points of light may be considered its directional information. The present experiment is concerned with the relationship between such directional information and the threshold between apparent movement and apparent successiveness, the original hypothesis being that the greater the directional information, the higher the threshold of movement. In fact, contrary results were obtained. Thresholds were obtained under conditions where movement could occur in either eight directions or only in two directions, better and more persistent movement being found under the former conditions. But this result is obtained only when one measures thresholds by an ascending method: increasing the time separation between light points from optimal movement to successiveness. An hypothesis is proposed to explain the findings stated in terms of “attentional disarticulation”.
