Accuracy of weightbearing at three target levels during bilateral upright stance in patients with neuropathic feet and control subjects

The purposes of this study were to (1) describe errors in weightbearing at three target levels for patients with neuropathic feet and control subjects, (2) compare the absolute errors at the three target levels between groups, and (3) identify predictor variables of errors in weightbearing by the neuropathic group. The groups of 26 subjects were matched for age and height. Weightbearing was measured with digital scales while subjects attempted to adjust their weight through a designated lower extremity to each target level (25, 50, and 75% of body weight). Analysis of variance indicated no significant difference in the percentage weightbearing between groups at the three target levels. There was a significant difference in errors made in weightbearing by the groups at the three target levels. Mean errors ranged from 8.5 to 9.7% for the neuropathic group and from 2.4 to 6.6% for the control group. The findings cast doubt on the utility (in the absence of feedback) of requesting individuals, particularly those with neuropathic feet, to weightbear at specific target levels.     

Comparison of two locus of control scales in predicting relapse in an alcoholic population

A 3-mo. follow-up was made of 64 male veterans who were discharged from a 21-day Alcohol Detoxification Treatment Program at the Veterans Affairs Medical Center at Lyons, NJ. Scores on the Rotter I-E and Alcohol Responsibility Scales were significantly correlated with tendencies toward a more external direction among the 13% who relapsed, significant on the I-E scale and nonsignificant on the Alcohol Responsibility Scale. When tests were compared as possible predictor variables of alcoholic relapse, the difference in favor of the I-E scale was statistically nonsignificant.     

Developmental perspectives on the localization and detection of auditory signals

Responsiveness of 1-, 3-, and 5-year-old children and adults to octave-band noises at .4 and 10 kHz was assessed with a go/no-go version of visual reinforcement audiometry (VRA) (Moore, Thompson, & Thompson, 1975) and a two-alternative, forced-choice version (Suzuki & Ogiba, 1961; Trehub, Schneider, & Endman, 1980). Infants performed better on the two-alternative, forced-choice version in quiet and in noisy backgrounds, and adults performed better on the two-alternative, forced-choice version in quiet but not in noisy backgrounds. Performance on the two tasks was essentially equivalent for 3- and 5-year-old children. Superior performance on two-alternative VRA over go/no-go may be due to lesser cognitive demands in the case of infants and to the engagement of superior decision strategies in the case of adults.     

On the scope of alcohol expectancy research: remaining issues of measurement and meaning

An article by Leigh (1989d) examined certain substantive and measurement-related limitations of research on alcohol outcome expectancies. Leigh (1989d) criticized research in this field on both conceptual and methodological grounds and speculated on future theoretical directions for research in the field. In their response, Goldman, Brown, Christiansen, and Smith (1991) contended that Leigh's critique is faulty in important respects. However, some of their points are based on misinterpretations of Leigh's comments, and they appear to have insufficient appreciation of conditions necessary for comprehensive measurement validation and for meaningful application of theories of memory to alcohol expectancy research. Despite the limitations of expectancy research, exciting avenues exist for further work.     

Neuropsychological correlates of hypertension: review and methodologic considerations.

Essential hypertension is a chronic disorder having many potential physical and behavioral sequelae. This article evaluates the impact of hypertension on neuropsychological test performance. First, cross-sectional and longitudinal studies that examine the neuropsychological correlates of hypertension are reviewed. In general, hypertensives are found to perform more poorly than normotensives, particularly on tests of memory, attention, and abstract reasoning, and less consistently on tests of perception, constructional ability, mental flexibility, and psychomotor speed. Next, the influence of variables that may moderate relationships between hypertension and neuropsychological performance--such as age, education, and medication usage--are examined. Finally, potential mechanisms, both physiological and psychological, underlying associations between hypertension and neuropsychological performance are discussed.     

Effects of Eltoprazine Hydrochloride on Predatory Behavior in Rats

Treatment of rats with the potent antiaggressive compound eltoprazine hydrochloride (1.0 & 2.0 mg/kg) slowed both predatory attack and killing of frogs. These results demonstrate a specific predation-inhibiting action of the drug which is not obscured by the elements of conspecific aggression seen during muricide. Unlike the closely related compound fluprazine, eltoprazine increased both attack and kill latencies implying that the effects of the two drugs on predation are mediated by at least somewhat distinct drug actions. It is further suggested that eltoprazine may be more specifically antiaggressive in its actions than related phenylpiperazine compounds.

     

On the nature of attachment in a borderline population: a preliminary investigation

Analyses of interpersonal behavior within a borderline population usually focus on object relations variables. In contrast, this preliminary research focuses on the nature of attachment styles and its relation to behavioral pathology. 24 hospitalized borderline patients were administered an Attachment Style Inventory and Millon Clinical Multiaxial Inventory. Analysis confirms predicted differences in attachment style between the borderline and normal control samples as well as indicates that a dependent style of attachment within this borderline sample is associated with less pathology than an avoidant, hostile, or resistant/ambivalent style. The implications of this preliminary work for full-scale research are addressed.     

Childhood peer rejection,aggression, withdrawal,and perceived competence as predictors of self-reported behavior problems in preadolescence

Childhood peer rejection, aggression, withdrawal, and perceived competence were compared as predictors of self-reported behavior problems. Peer sociometric status (Coie, Dodge, and Coppotelli, 1982), teacher ratings of behavior problems (Lorion, Cowen, & Caldwell, 1975), and perceived competence ratings (Harter, 1982) were obtained for 613 second-through fourth-grade children. Two years later, these students completed a modified version of the Youth Self-Report form (Achenbach & Edelbrock, 1987). Rejected children and neglected girls were more likely to have a self-reported nonspecific negative outcome than others. Neglected girls were at heightened risk for depression. A varied set of predictors obtained from different informants emerged for each sex for each of the specific self-reported outcomes of depression, unpopularity, delinquency, aggression, and self-destructive/identity problems. Results are discussed in terms of future directions for longitudinal research on the consequences of poor peer relationships in childhood.This research was supported in part by a grant from the W.

Rhythmic motor behavior of preambulatory motor impaired,down syndrome and nondisabled children: A comparative analysis

The developmental course of rhythmic motor behavior was followed longitudinally for three groups of preambulatory children — normally developing, Down syndrome, and those with profound motor impairment. The groups differed in chronological age but were comparable with respect to motor age. The motor impaired subjects displayed significantly less rhythmic motor behavior than the nondisabled and Down syndrome groups. In comparing particular subtypes of rhythmic motor behavior, differences were found in both the average number of bouts and duration of subtypes among the groups. Longitudinal analyses of the data over the entire observation period revealed that the rhythmic motor behavior of the children with Down syndrome was more similar to that exhibited by the nondisabled children than was the rhythmic motor behavior of the children with motor impairment. However, there was considerable variability among the groups in several particular subtypes.This research was supported by grants from the National Institute of Child Health and Human Development (HD 17650 and HD 07226).The authors acknowledge the assistance of Robert E. Arendt, Grant Youngquist, Michael Hohn, and Charles Lowitzer in obtaining the observational data and thank the families of the subjects for their enthusiasm and dedication to the project.This study was presented at the 23rd Annual Gatlinburg Conference on Research and Theory in Mental Retardation and Developmental Disabilities, April 21, 1990.
