Differential effects of massage and heelstick procedures on transcutaneous oxygen tension in preterm neonates

The present study investigated the differential effects of heelsticks and tactile-kinesthetic massage on transcutaneous oxygen tension (TcPO₂) in preterm infants. The sample was comprised of 37 stabilized preterm neonates from the Neonatal Intensive Care Unit. During the heelstick procedure, TcPO₂ significantly declined an average of 14 mmHg. When compared to the tactile-kinesthetic massage, TcPO₂ levels during the heelstick (M = 39.8) were significantly lower than during the stimulation (M = 72.8). Mean TcPO₂ levels remained clinically safe during the four massage sessions evaluated. The TcPO₂ levels during kinesthetic stimulation were somewhat more varied, and movement and pressurization of the TcPO₂ electrode were investigated as possible artifactual explanations for this phenomenon. Overall, the findings indicate that social forms of touch such as tactile-kinesthetic massage do not appear to have a medically compromising effect on TcPO₂ in the preterm neonate. These findings are evaluated in relation to the “minimal touch” policy, and implications for future handling of the stabilized preterm neonate are discussed.     

Countertransference and the developing family therapist: Treatment and supervision issues

All therapists experience reactions toward clients, which have traditionally been called countertransference. Such reactions toward families pose special issues for beginning and developing family therapists. This clinically based and clinically oriented article describes some of the reactions, clues pointing to their existence, and indicates some of the ways beginning and developing family therapists and their supervisors and consultants can deal constructively with these reactions.     

Some perceptual properties of consonants in multitalker babble

This study investigated whether consonant phonetic features or consonant acoustic properties more appropriately describe perceptual confusions among speech stimuli in multitalker babble backgrounds. Ten normal-hearing subjects identified 19 consonants, each paired with /a/, 1–19 and lui in a CV format. The stimuli were presented in quiet and in three levels of babble. Multidimensional scaling analyses of the confusion data retrieved stimulus dimensions corresponding to consonant acoustic parameters. The acoustic dimensions identified were: periodicity/burst onset, friction duration, consonant-vowel ratio, second formant transition slope, and first formant transition onset. These findings are comparable to previous reports of acoustic effects observed in white-noise conditions, and support the theory that acoustic characteristics are the relevant perceptual properties of speech in noise conditions. Perceptual effects of vowel context and level of the babble also were observed. These condition effects contrast with those previously reported for white-noise interference, and are attributed to direct masking of the low-frequency acoustic cues in the nonsense syllables by the low-frequency spectrum of the babble.     

Positive life events and social support and the relationship between life stress and psychological disorder

Conclusion In conclusion, the present research demonstrated the deleterious effects of negative life events. Number of negative events was a significant predictor of psychological disorder even when initial disorder was statistically controlled. The cross-sectional regression findings provided some support for the stress-buffering effects of positive life events, but these effects were nonsignificant when initial disorder was statistically controlled. The cross-sectional and prospective regression findings suggest that received social support, as measured by the ISSB, does not have a direct or stress-buffering effect on psychological disorder. These analyses, however, demonstrated the direct and stress-buffering effects of perceived social support, as measured by the ISEL, and the data suggest that the ISEL is a promising measure of this construct.The authors thank Sheldon Cohen who provided helpful comments on an earlier version of this article.     

Feminine sex role and depression in middle-aged women

The present study was designed to investigate the relationship of sex-role orientation and depression in middle-aged women. It was hypothesized that middle-aged females who were clinically depressed would score higher in feminine characteristics on the Bem Sex Role Inventory (BSRI) than similar women who were not depressed. The subjects were two groups of women between the ages of 35 and 50. The clinical group consisted of 15 women who were currently diagnosed as depressive and who were undergoing treatment for depression at three local mental health centers. The nonclinical group consisted of 24 women who were not currently seeking treatment for depression and who had never undergone psychiatric treatment or therapy. All subjects were administered the BSRI and Beck's Depression Inventory.Results supported the hypothesis that depression in middle-aged females is related to their degree of acceptance of the traditional feminine role. For all subjects, depression scores were positively correlated with femininity scores. It was concluded that the woman who subscribes to a traditional feminine role stereotype has a greater vulnerability to depression in her middle years.     

A comparison of adult males' and females' interactions with girls and boys

The verbal interactions of adult males and females with trained girl and boy confederates were compared in an unstructured and an immediately following structured situation. Women did not respond differently based on the child's gender in either situation, while men spoke more and used longer mean length of utterances with the boys than with the girls in the unstructured situation. In the structured situation males did not respond differently to girls and boys, speaking more to both than did females. Correlations between the number of words spoken in female-child pairs were higher, suggesting a greater reciprocity of interaction, than for male-child pairs in both situations. The results are seen as reflecting the outcome of differential sex-role socialization for men and women, especially with respect to children, with females socialized to relate with others and men to need to dominate others.     

TEACHER-VERSUS PEER-MEDIATED INSTRUCTION: AN ECOBEHAVIORAL ANALYSIS OF ACHIEVEMENT OUTCOMES

In three experiments, we compared the effects of instructional arrangements that varied in: (a) teacher versus peer mediators, (b) methods used, (c) levels of student academic responding generated, and (d) content taught and tested. Instructional arrangements (i.e., tasks, structure, teacher position, teacher behavior) and students' levels of academic responding were measured by an observation system which served as an index of the independent variables. Students' accuracy on weekly spelling, arithmetic, and vocabulary tests and pre- and post-standardized achievement tests (Experiments 2 and 3 only) were the dependent variables. Results indicated that the classwide peer tutoring, compared to the teacher's procedure, produced more student academic responding and higher weekly test scores, regardless of treatment order or subject matter content (Experiment 1). The four lowest performing students in each class, in particular, benefited from peer tutoring, often performing as well as the other students. These findings were replicated in Experiments 2 and 3 wherein content taught/tested was also manipulated. Standardized test score gains were higher in those areas in which peer tutoring was used longest. Issues related to the functional analysis of instruction and achievement gain are discussed.     

Noncompliance: Medical and Psychological Aspects

Patient noncompliance to oral medication regimens was assessed by interview in a sample of 109 private practice patients at two pharmacies in an outer western suburb of Sydney. Patients were classified into one of the five following groups on the basis of their stated degree of noncompliance to all medications taken (perfect compliance on all medications, occasional noncompliance on all medications, frequent noncompliance on all medications, occasional noncompliance on only some of the medications taken, and frequent noncompliance on only some of the medications taken). Selected medical/phnrmacological, doctor-patient relationship, attitudinal and personality variables were measured and univariate and multivariate analyses of the data undertaken. Contrary to expectations, the total number of medications reportedly taken rind complexity of the regimen were inversely related to noncompliance. Respondents reported satisfaction with the doctor's consultations, skepticism of doctors, attitudes to medication and scores on Rotter's (1966) Internal-External Locus of Control Scale (IEC) did not distinguish the compliant group from the four noncompliant groups combined. The most noteworthy finding concerned the marked ditlerences between the noncompliant groups, especially in relation to the patient's opinion of having to take the medication and the Personal Control scores of the IEC.     

Patterns of regional cerebral blood flow during attempted reading aloud by stutterers both on and off haloperidol medication: Evidence for inadequate left frontal activation during stuttering

Two stutterers, both recent college graduates, were subjected to regional cerebral blood flow measurements while attempting to read aloud. Each one received two measurements, one of which was under the influence of haloperidol, 3 mg daily. Both subjects showed improvement on medication, allowing a stuttering versus essentially no stuttering comparisons for each subject. Both subjects showed higher Broca's area flow in the right compared to the left hemisphere, during stuttering. Both showed higher Wernicke's area flow in the left compared to the right hemisphere, however, during stuttering. During reading aloud without stuttering, however, the Brocas's area flows were reversed, now showing a left hemisphere advantage. The results were interpreted as consistent with H. M. Sussman and P. F. MacNeilage's (1975, Neuropsychologia, 13, 19–26) proposal that stutterers exhibit conventional left cerebral dominance for speech reception, but inadequate left cerebral dominance for speech production.
