Biofeedback as a treatment for childhood hyperactivity: a critical review of the literature

Hyperactivity is a significant problem for which no causal theories have been unequivocally substantiated and one in which treatment approaches have met with limited success. Recent research in behavioral medicine has brought biofeedback into use as a treatment for disorders that are mediated by physiologic functioning, with hyperactivity as one such disorder. 36 studies are reviewed in which biofeedback was used as a treatment for hyperactivity. This review indicated that biofeedback treatments alone have not been effectively evaluated, and methodological problems with the current studies severely limit generalizations that may be made to hyperactive populations. Biofeedback in conjunction with other techniques appears to have promise for reducing some of the behavioral symptoms of the hyperactivity syndrome. Directions for further research are presented.     

The relationship between eye position and egocentric visual direction

Hering’s model of egocentric visual direction assumes implicitly that the effect of eye position on direction is both linear and equal for the two eyes; these two assumptions were evaluated in the present experiment. Five subjects pointed (open-loop) to the apparent direction of a target seen under conditions in which the position of one eye was systematically varied while the position of the other eye was held constant. The data were analyzed through examination of the relationship between the variations in perceived egocentric direction and variations inexpected egocentric direction based on the positions of the varying eye. The data revealed that the relationship between eye position and egocentric direction is indeed linear. Further, the data showed that, for some subjects, variations in the positions of the two eyes do not have equateffectsTjn egocentric direction. Both the between-eye differences and the linear relationship may be understood in terms of individual differences in the location of the cyclopean eye, an unequal weighting of the positions of the eyes in the processing of egocentric direction, or some combination of these two factors.     

Culturally grounded strategies for suicide and alcohol risk prevention delivered by rural Alaska Native communities: A dynamic wait-listed design evaluation of the Qungasvik intervention

We examined the effectiveness of the Qungasvik (Tools for Life) intervention in enhancing protective factors as a universal suicide and alcohol prevention strategy for young people ages 12−18 living in highly affected rural Alaska Native communities. Four communities were assigned to immediate intervention or to a dynamic wait list. Outcomes were analyzed for 239 young people at four time points over two years of community intervention. Outcomes assessed two ultimate variable protective factors buffering suicide and alcohol risk, and three intermediate variable protective factors at the individual, family, and community level. Dose dependent intervention effects were associated with growth in ultimate but not intermediate variables. This evaluation of the Qungasvik intervention provides support for the effectiveness of its Indigenous strategies for suicide and alcohol misuse prevention in this rural Alaska Native setting. Though findings did not provide support for a theory of change where growth in ultimate variables is occasioned through effects on intermediate variables, research designs focused on young people who enter intervention at lower levels of preexisting protection hold promise for better understanding of intervention change processes. The Qungasvik intervention is responsive to an acute public health need for effective rural Alaska Native suicide and alcohol risk prevention strategies.     

Motivated to Forgive? Partisan Scandals and Party Supporters

In this study, we investigate how partisan motivations shape voters' reactions to a political scandal by drawing on a unique survey experiment fielded immediately after Justin Trudeau's brownface/blackface scandal broke during the 2019 Canadian election. We thus explore motivated reasoning in real time in a competitive and highly partisan election context. Are voters more willing to forgive politicians for past behavior when their own party leader's impropriety is cued? To what extent do personal interests, such as cross-pressures or electoral concerns, affect the motivation to forgive? Our findings show that partisan-motivated reasoning is overwhelmingly powerful, producing politically biased judgments of politicians implicated in scandals. Furthermore, voters' willingness to forgive scandals is also influenced by “strategic” considerations, in that preferences over which political party wins or loses in the election affect opinions about whether someone should be forgiven or whether the scandal is considered important at all. However, we find no evidence that personal involvement in the issue raised by the scandal conditions partisan motivations. We posit that the environment—in this case, a competitive election—is an important consideration for understanding the extent and limits of partisan-motivated reasoning.     

Self-report measure of parental reflective functioning: A study of reliability and validity across three samples of varying clinical risk

The Parental Reflective Functioning Questionnaire (PRFQ) provides an efficient way to measure a parent's capacity to recognize their child's mental states and to understand the relationship between underlying mental states and behavior. To date, limited work evaluates its psychometric properties beyond initial validation studies. Here we examined the reliability and validity of the PRFQ in three samples of varying clinical risk (e.g., community sample, previous mental health diagnosis, substance use disorder diagnosis). Across samples, the majority (e.g., 75%–78%) of mothers identified as White; all mothers were from the USA. We compared the PRFQ to task-based measures of mentalization, the Parent Development Interview (PDI), and measures of the parent-child relationship. The PRFQ was a reliable measure across samples, and it was associated in theoretically consistent ways with task-based measures of mentalization. Parental RF across the PDI and PRFQ were not highly correlated in a sample of mothers with substance use disorders. Existing RF measures may be tapping into a different component of the broader construct of parental reflective functioning (PRF). The PRFQ was further validated by demonstrating relationships with parent-report measures of the parent-child relationship. Taken together, these findings provide additional support for the reliability and validity of the PRFQ.     

Sports specific metacognitions and competitive state anxiety in athletes: A comparison between different sporting types

This study investigated the relationship between sport related metacognitions with state anxiety dimensions, and compared how sporting categories affected these variables, among an online sample of athletes (N = 187). A MANOVA revealed there were significant differences between sporting types in metacognitive beliefs relating to the utility of rumination and arousal, the need to control thoughts, and levels of somatic anxiety. Correlations and multiple regressions showed that that in contrast to the relationships with self-confidence, cognitive and somatic state anxiety were positively associated with specific dysfunctional metacognitive beliefs, but negatively related to metacognitive processes. Overall, these findings highlight that: (a) athletes might adopt metacognitions to meet the different cognitive demands of sport types; and (b) metacognitions are in part responsible for the occurrence of state anxiety and self-confidence during competitions. The findings of this study have implications toward how researchers and sports practitioners approach the comprehensive nature of competitive anxiety.     

A comparison of fixed momentary differential reinforcement of other behavior to variable momentary differential reinforcement of other behavior to reduce challenging behavior

Differential reinforcement of other behavior (DRO) is commonly used to reduce behavioral excesses. Momentary DRO schedules involve delivery of reinforcement contingent upon the absence of the target behavior at a given moment. Two variations of momentary DRO exist: fixed-momentary (FM) DRO and variable-momentary (VM) DRO. In the current study, we directly compared FM-DRO and VM-DRO schedules to reduce challenging behavior maintained by automatic reinforcement exhibited by four children with autism spectrum disorder. The results suggest that both the DRO schedules were equally effective to reduce challenging behavior. A social validity measure showed that most caregivers rated the VM-DRO as a preferred schedule and noted the potential for FM-DRO schedule to become more discriminable over time, which could reduce its effectiveness. However, most caregivers also commented that the FM-DRO schedule was easier to implement.     

Sensorimotor and working memory systems jointly support development of perceptual rhythm processing

We studied the role of sensorimotor and working memory systems in supporting development of perceptual rhythm processing with 119 participants aged 7–12 years. Children were assessed for their abilities in sensorimotor synchronization (SMS; beat tapping), auditory working memory (AWM; digit span), and rhythm discrimination (RD; same/different judgment on a pair of musical rhythm sequences). Multiple regression analysis revealed that children's RD performance was independently predicted by higher beat tapping consistency and greater digit span score, with all other demographic variables (age, sex, socioeconomic status, music training) controlled. The association between RD and SMS was more robust in the slower tempos (60 and 100 beats-per-minute (BPM)) than faster ones (120 and 180 BPM). Critically, the relation of SMS to RD was moderated by age in that RD performance was predicted by beat tapping consistency in younger children (age: 7–9 years), but not in older children (age: 10–12 years). AWM was the only predictor of RD in older children. Together, the current findings demonstrate that the sensorimotor and working memory systems jointly support RD processing during middle-to-late childhood and that the degree of association between the two systems and perceptual rhythm processing is shifted before entering into early adolescence.
