Cross-Age Peer Tutoring and Fluency-Based Instruction to Achieve Fluency with Mathematics Computation Skills: A Randomized Controlled Trial

The current study employed a randomized controlled trial to evaluate the use of peer tutoring and fluency-based instruction to increase mathematics fluency with addition and subtraction computation skills. Forty-one elementary school students between the ages of eight and 12 years participated in the 8-week study using cross-age peer tutoring, Say All Fast Minute Every Day Shuffled, frequency building, and the morningside math facts curriculum (Johnson in Morningside mathematics fluency: math facts (vol 1–6; curriculum program), Morningside Press, Seattle, 2008). Pre- and post-test measures of mathematics fluency and calculation were conducted with all participants. A measure of social skills and competing problem behaviors was also conducted at pre- and post-testing to evaluate any additional effects of the peer tutoring model. The results demonstrated a statistically significant difference between groups on measures of mathematics fluency, with the experimental group demonstrating significantly higher scores than the control group at post-testing. There were no significant differences between groups on measures of social skills and competing problem behaviors or calculation. The findings indicate that cross-age peer tutoring and fluency-based instruction resulted in positive outcomes for tutees in the mathematics domain, specifically mathematics fluency.     

Change in Maternal Stress for Families in Treatment for their Children with Oppositional Defiant Disorder

Our objective was to predict change in maternal stress over the course of a randomized clinical trial comparing the efficacy of two interventions for Oppositional Defiant Disorder (ODD): Parent Management Training and Collaborative & Proactive Solutions. In a secondary analysis of data collected from this randomized clinical trial, we examined whether children’s self-reported positive relations with their parents impacted responsiveness to treatment, which in turn impacted maternal stress. One hundred thirty-four children and their parents (38.1% female, ages 7–14, M age?=?9.51, SD?=?1.77) were tracked across three time points: pre-treatment; one-week post-treatment; and six-month post-treatment. Hierarchical linear models tested change in children’s reports of positive relations with parents, clinician reports of ODD severity, and maternal reports of parenting stress. Models then tested multilevel mediation from positive relations with parents, through ODD severity, onto maternal stress. Hypothesized indirect effects were supported such that children’s reports of positive views toward parents uniquely predicted reductions in ODD severity over time, which in turn uniquely predicted reductions in maternal stress. Results highlight the promise of potential secondary benefits for parents following interventions for children with oppositional problems. Furthermore, results underscore the importance of the parent–child relationship as both a protective factor and as an additional target to complement interventions for child disruptive behaviors.     

Ecological Networks and Community Attachment and Support Among Recently Resettled Refugees

Interventions aimed at enhancing mental health are increasingly centered around promoting community attachment and support. However, few have examined and tested the specific ecological factors that give rise to these key community processes. Drawing from insights from the ecological network perspective, we tested whether spatial and social overlap in routine activity settings (e.g., work, school, childcare) with fellow ethnic community members is associated with individuals’ attachment to their ethnic communities and access to social resources embedded in their communities. Data on routine activity locations drawn from the Refugee Well‐Being Project (based in a city in the Southwestern United States) were used to reconstruct the ecological networks of recently resettled refugee communities, which were two‐mode networks that comprise individuals and their routine activity locations. Results indicated that respondents’ community attachment and support increased with their ecological network extensity—which taps the extent to which respondents share routine activity locations with other community members. Our study highlights a key ecological process that potentially enhances individuals’ ethnic community attachment that extends beyond residential neighborhoods.     

Nature,nurture, and capital punishment: How evidence of a genetic–environment interaction,future dangerousness,and deliberation affect sentencing decisions

Research has shown that the low‐activity MAOA genotype in conjunction with a history of childhood maltreatment increases the likelihood of violent behaviors. This genetic–environment (G × E) interaction has been introduced as mitigation during the sentencing phase of capital trials, yet there is scant data on its effectiveness. This study addressed that issue. In a factorial design that varied mitigating evidence offered by the defense [environmental (i.e., childhood maltreatment), genetic, G × E, or none] and the likelihood of the defendant's future dangerousness (low or high), 600 mock jurors read sentencing phase evidence in a capital murder trial, rendered individual verdicts, and half deliberated as members of a jury to decide a sentence of death or life imprisonment. The G × E evidence had little mitigating effect on sentencing preferences: participants who received the G × E evidence were no less likely to sentence the defendant to death than those who received evidence of childhood maltreatment or a control group that received neither genetic nor maltreatment evidence. Participants with evidence of a G × E interaction were more likely to sentence the defendant to death when there was a high risk of future dangerousness than when there was a low risk. Sentencing preferences were more lenient after deliberation than before. We discuss limitations and future directions.     

The MMPI–2 Restructured Clinical (RC) Scales and Redundancy: Response to Tellegen,Ben-Porath,and Sellbom

In this article, we examine 5 criticisms of Tellegen, Ben-Porath, and Sellbom (2009/this issue) about our study demonstrating the redundant relationships of the Restructured Clinical (RC) scales with extant MMPI–2 scales. We discuss differences in univariate versus multivariate comparisons of the RC scales and our “proxy” scales using their data. We show that (a) both the RC and extant proxy scales identified in our analyses account for most of the variance in the Clinical scales; (b) the proxy scales are redundant with the RC scales; (c) the proxy scales matched the 6 RC scales in accounting for variance in the Clinical scales exactly in three cases, differed by ≤.02 in 2 cases, and reached a maximum of .11 in one case; (d) the item overlap between RC1 and HEA is not at issue but rather their correlation with Scale 1; and (e) the evidence for the construct validity of the RC scales is weak using findings on the incremental validity of RC4 as illustrative.     

The Duty to Support Nationalistic Policies

We demonstrate that citizens perceive a duty to support policies that benefit their nation, even when they themselves judge that the consequences of the policies will be worse on the whole, taking outsiders into account. In terms of actions, subjects think they would do their perceived duty rather than violate it for the sake of better consequences. The discrepancy between duty and judged consequences does not seem to result from self‐interest alone. When asked for reasons, many subjects felt an obligation to help their fellow citizens before others, and they also thought that they owed something to their nation, in return for what it did for them. The obligation to help fellow citizens was the strongest predictor of perceived duty. In an experiment with Israeli and Palestinian students, group membership affected both perceived overall consequences and duty, but the effect of group on perceived consequences did not account for the effect on perceived duty.

Specificity of MMPI cluster types to chronic illness

Abstract

Cluster analysis derived MMPI profile types were compared for three distinct illness populations: chronic low back pain (CLBP), mixed headache (HA), and cardiac disease (CD). Results replicated previous findings in the chronic pain and cardiac literatures. Differences between diagnostic groups and genders were found for the prevalence of the derived MMPI profile types. Results indicated that, in males, the two chronic pain groups had similar profile types and similar relative frequencies of these types, but both differed from the CD sample. The chronic pain groups tended to have a greater number of patients with pathological and distressed MMPI profile types and a lesser representation in the subclinical profile type compared to the CD sample. Similar findings were obtained for females, though the CLBP group tended to have a higher frequency of highly distressed, pathological profiles than either the HA or CD groups. Results suggested that the MMPI may be a measure of response to illness rather than reflecting predisposing personality types for any given illness and that the higher frequency of highly distressed profiles in the chronic pain samples reflects the increased suffering of those populations compared to other illnesses.     

Paradoxical effects of presentation modality on false memory.

Two experiments are reported in which the effects of presentation modality on false memory in recall and recognition are studied. False recall and recognition of critical targets are lower for non-presented items related to a study list when that study list is presented visually than when presented auditorily. This pattern of low levels of false memory for critical targets holds even when participants read the visually presented study items aloud. These results suggest that recollection of visual detail plays a role in the prevention of false memory. However, both the hit rates (true memory) and the false-alarm rates to weakly related distractors (non-critical targets) were higher for visual presentation than for auditory presentation, suggesting that more than one mechanism may underlie false recognition.     

At the Edge of Eternity's Shadows: Scaling the Fractal Continuum from Lower into Higher Space

In this paper, I elaborate the hyperspatial implications of the fractal-scaling scheme that I introduced previously. Four case examples where out-of-body experiencers reported heightened and amplified visual capacities are correlated with this explanatory model. Three of these cases are identified as including an additional hyperspace signifier, the reported capacity to see through solid and opaque physical obstructions. One of these cases included yet another hyperspace signifier, the reported capacity to pass through such obstructions. Additional evidence supportive of this thesis is drawn from the literature on ecstatic experience, including out-of-body, near-death, and other varieties of mystical or visionary experience, and from that on psychedelic experience. Yet other hyperspace signifiers reported by ecstatic voyagers are also considered, including sensations of seeing outward spherically in 360 degrees and of seeing on all sides of three-dimensional solids simultaneously.
