The effects of attentional shift training on the execution of soccer skills: A preliminary investigation

One of the most important skills in soccer is the ability to respond quickly and accurately to the changing demands of the competitive environment (i.e., position of ball, teammates, opponents). A multiple baseline design across 4 male collegiate soccer players was used to determine the effectiveness of an attentional training program on the execution of targeted soccer skills. The treatment included information and laboratory attentional shift exercises followed by practice of attentional shifting skills on the execution of different soccer exercises. Following treatment, the accuracy of execution of the experimental soccer drill improved.     

Reflections on change in science and religion

Science and the Catholic church are both conservative, slow-to-change institutions. However, science has institutionalized procedures that ensure that ample amounts of criticism of currently accepted theories and methodologies will always be present. This arrangement of continuous conjectures and refutation in science ensures often slow but steady change. Because supporters often think of religions as trafficking in timeless truths, criticism of church beliefs and practices (even when intended to stimulate reflection and improvement) is frequently seen as being disloyal to the institution. Because of the growing crises caused by world overpopulation, I argue that the Catholic church's opposition to all artificial methods of birth control now lacks whatever moral force it might have had when originally promulgated. By highlighting theological perspectives that might be appropriate for the ecological realities of the 21st century, I hope the church will see the wisdom of reevaluating many of its positions in the light of rapidly approaching ecological imperatives.     

The development of aggression in toddlers: A study of low-income families

The effort by developmental psychopathologists to understand the etiology of antisocial behavior has resulted in several significant findings. First, aggressive behavior is highly stable from early childhood into adolescence and adulthood. Second, parental factors including rearing practices and parental psychopathology, are correlated with childhood behavior problems. It was the aim of the present study to examine the correlates and stability of aggressive behavior in a sample of toddlers from low income families. Eight-nine mother-child dyads (52 boys and 37 girls) were observed in laboratory assessments when the child was 18- and 24-months old. Frequency and pervasiveness of aggression were coded from videotapes. Familial criminality, maternal depressive symptomatology, child noncompliance, and difficult child temperament were examined as contributors to the prediction of aggression in toddlers. Stability of aggression was moderate, especially for aggression occurring in low-stress situations. While there were few sex differences in the frequency and stability of aggression, there were marked differences in the correlates and predictors of aggression. Gender-specific, interactional models of the development of aggression are proposed.This study was supported by grants to Daniel Shaw and Joan Vondra from the following organizations within the University of Pittsburgh: the Mental Health Clinical Research Center for Affective Disorders, the Office of Child Development, the School of Education in conjunction with the Buhl Foundation, and the Faculty of Arts and Sciences. Portions of this paper were presented at the Meeting for the Society for Life History Research, Philadelphia, April 1992. The authors would like to acknowledge the contribution of Julie Alley, Jodi Chusta, and Kevin Cosley for their invaluable assistance in behavioral coding. Special thanks is given to the mothers and children who participated in this research.     

Taking an individualized approach to the assessment of self-efficacy and the prediction of alcoholic relapse

The present study reports on a clinical instrument designed for assessing self-efficacy in alcoholics. In contrast to studies that construct general measures, it was proposed that taking an individualized approach to assessment might offer an effective methodology. Thirty-four alcoholics in an outpatient, behaviorally oriented treatment program participated as subjects. During therapy, an Individualized Self-Efficacy Survey (ISS) was developed for each subject. The ISS was developed by (a) administering the Drinking Patterns Questionnaire (DPQ) to identify important problem areas (e.g., work, children, marital) and specific drinking antecedents and (b) constructing a 15-item scale using each drinker's most important cues. The utility of having clients choose their own items was supported by finding a significant relationship between problem areas identified as important on the DPQ and the areas reported as surrounding relapse. ISS ratings were reflective of efficacy changes during treatment, while posttreatment ISS scores were predictive of subsequent relapse. Situation-specific prediction of relapse was not found. The advantages of this methodology for clinical use are discussed, while general directions for future research are suggested.     

A comparison of instruction formats for administering a computerized behavioral test

Shaping and fading techniques were employed to replace written instructions used in computerized behavioral tests. Apple Macintosh computers and HyperCard with Pascal extensions were chosen as the development environment to implement the new techniques. Initial Findings demonstrate the effectiveness and relative efficiency of shaping techniques to teach correct performance on the Symbol-Digit Test.     

The effect of gap depth on the perception of whether a gap is crossable

Four experiments were performed in order to examine the effect of gap depth on human observers’ perception of whether or not a gap is crossable. Experiments 1 and 2 showed that as the gap’s depth increased, observers tended to increasingly underestimate the maximum width of a gap they could step across. Experiments 3 and 4 clarified this finding: The observed covariation of perceived gap crossability and gap depth depended on the observer’s direction of gaze, rather than on the physical depth of the gap. The optical relations to which observers might be attending are discussed, as well as the possibility that cognitive-affective processes might have contributed to observers’ underestimation of their actual capabilities.     

Resetting the pitch-analysis system: 1. Effects of rise times of tones in noise backgrounds or of harmonics in a complex tone

The question of whether sudden increases in the amplitude of pure-tone components would perceptually isolate them from a more complex spectrum was investigated in two experiments. In Experiment 1, a 3.5-sec noise was played as a masker. During the noise, two pure-tone components of different frequencies appeared in succession. Subjects were asked to judge whether the pitch sequence went up or down. The rise time of these components had only a small and inconsistent effect on discrimination. In Experiment 2, the 3.5-sec background signal was a complex tone. The amplitudes of two of its components were incremented in succession. Again, subjects judged whether the pitch pattern went up or down. This time there was a sizable, monotonic effect of the rise time of the increments, with more rapid increments leading to better discrimination. The difference between the two results is interpreted in terms of the auditory system’s response to changing and unchanging signals and the role of its “sudden-change” responses in attracting perceptual processing to certain spectral regions.     

Relatives' Perceptions of Their Interactional Behavior with a Schizop/hrenic Family Member

Relatives' (N = 77 ) perceptions of their recent interactional behavior with a schizophrenic family member (N = 51 ), as measured by an adjective checklist, were compared with outside observer ratings of the relatives' Affective Style (AS) and the patients' Coping Style (CS) during a family interaction task. Results indicated that, overall, the relatives in the present sample perceived their own interactional behavior toward the patient, as well as the patients' behavior toward them, in a way that paralleled their affective behavior as assessed by outside raters. Moreover, the relatives' rated their relationship with the patient in a fashion that was more predictive of the observed interactional behavior of both the relatives and the patients than were the outside observers' ratings of the relatives' Expressed Emotion (EE) measured either at the patients' index hospitalization (using the Camberwell Family Interview, CFI-EE) or during the post-discharge period (assessed with a brief Five-Minute Speech Sample method, FMSS-EE).     

Clues to Suicide,Reconsidered

This brief paper focuses on a rather recondite aspect of the suicidal scenario: dissembling (feigning, pretending, withholding). Most individuals who commit suicide exhibit prodromal indicia in the month before. These verbal and behavioral clues are found in about 90% of psychological autopsies of suicidal deaths. As for the other 10% who mask or hide their lethal intentions, we do well to assume that even some hidden clues might be deciphered by the skillful clinician or the alert friend or colleague.     

ANALYZING ALERTNESS AMONG PEOPLE WITH PROFOUND MULTIPLE DISABILITIES: IMPLICATIONS FOR PROVISION OF TRAINING

We investigated whether variations in alertness among individuals with profound multiple disabilities affected subsequent responsiveness to training programs. Three experiments were conducted involving 5 people. In Experiment 1, results indicated that alertness of 3 individuals increased with provision of skill-acquisition training programs. Results also indicated no predictive relationship between alertness levels prior to training and subsequent responsiveness to training. Experiment 2 replicated results of Experiment 1 with 2 participants from Experiment 1 and an additional participant. Results of Experiment 2 also indicated that the increased alertness levels accompanying provision of training were not a function of the participants simply being in an inactive environment prior to training. Results of Experiment 3 indicated that alertness of an additional participant increased through provision of another training intervention, involving a systematic preference assessment. Responses during the preference assessment appeared to be unrelated to previously existing alertness levels. These findings suggest the need for caution when considering the withholding of scheduled training because an individual appears to be nonalert.
