Effect of fine motor skills training on arithmetical ability in children

Previous researches have shown that there was a strong relationship between fine motor skills and arithmetical abilities in children. However, the majority of previous studies examined only the correlations between fine motor skills and arithmetical abilities, but did not attempt to determine their causal relationship. Thus, the aim of the present study was to examine the effect of motor skills training on arithmetical abilities among 80 first graders. One of the results showed that the intervention group, which received training in fine motor skills for 10 min, showed greater improvements in performance on an arithmetic task and a pegboard than did the active control group, which read their favourite book for 10 min. These findings have suggested that training in this study is an appropriate program for improving fine motor skills and further fine motor skills had a significant influence on arithmetical abilities in children, with a medium effect size. The present study has, for the first time, provided evidence that there will be a causal relationship between these factors.     

Unconscious integration of pointing relation between two masked arrows

In the present study, by using a briefly masked prime display paradigm, we investigated whether the pointing relation (same or different) between two unconsciously perceived arrows in the prime could be processed. Since only motor response priming can reflect unconscious processing of two arrows’ pointing-direction relation (i.e., a relational integration), we could distinguish the motor response priming from the visual priming in this study which in other studies were not separated. We also manipulated the prime-to-target stimulus onset asynchronies (SOA) by using a 70?ms and a 180?ms SOA. In this experiment, two masked arrow signs pointing in the same or different directions (> > or > <) were simultaneously presented in the prime, followed by two arrow symbols also pointing in the same or different directions in the target. The participants were asked to decide whether the two arrows in the target were pointing in the same or different directions. The results did not show any visual priming effect, but did show that the unconsciously perceived pointing relation in the prime elicited a positive motor response priming effect in RT under the 70?ms SOA condition, and a negative motor response priming effect in accuracy under the 180?ms SOA condition. The results were discussed in terms of self-motor-inhibition (or mask-triggered inhibition) and attention mechanisms. Overall, this study indicated that the pointing relation between the two subliminal arrows in the prime could influence the subsequent responses to the target and suggested that people can integrate unconsciously perceived information.     

Predictors of Treatment Completion and Recidivism Among Intimate Partner Violence Offenders

This study examined the variables that predicted completion of an AMEND-Emerge-based program designed to treat men (n = 202) who had engaged in intimate partner violence and the rates of recidivism among those who completed versus those who failed to complete the program. Data were collected from an archival database that housed historical and demographic data on each participant; recidivism was determined by accessing publicly available court records, and was defined very broadly as any charges filed within a year after participating in the program. Overall recidivism for this sample was low (22.28%). Demographic factors demonstrated to correctly classify post-treatment recidivism included age, race, and relationship status. Whereas those who completed the program had lower recidivism than non-completers, the differences between those groups in age, race, and relationship status suggest that features of the program may not address the needs of younger African Americans who are not married.     

Using Curriculum-Based Measurements for Program Evaluation: Expanding Roles for School Psychologists

Educators increasingly need to evaluate schoolwide reform efforts; however, complex program evaluations often are not feasible in schools. Through a case example, we provide a heuristic for program evaluation that is easily replicated in schools. Criterion-referenced interpretations of schoolwide screening data were used to evaluate outcomes associated with participation in four-year-old kindergarten. Nonparametric analyses allowed for group comparisons across early literacy screening outcomes. Risk ratios demonstrated that four-year-old kindergarten participants were less likely to score “at-risk” on kindergarten and first grade screenings. The methods employed meaningfully addressed local program effectiveness questions. Further, they were easily determined and disseminated. Implications for extensions of the heuristic to other evaluation questions and data sources as well as limitations of the approach are discussed.     

Learning words and learning sounds: Advances in language development

Phonological development is sometimes seen as a process of learning sounds, or forming phonological categories, and then combining sounds to build words, with the evidence taken largely from studies demonstrating ‘perceptual narrowing’ in infant speech perception over the first year of life. In contrast, studies of early word production have long provided evidence that holistic word learning may precede the formation of phonological categories. In that account, children begin by matching their existing vocal patterns to adult words, with knowledge of the phonological system emerging from the network of related word forms. Here I review evidence from production and then consider how the implicit and explicit learning mechanisms assumed by the complementary memory systems model might be understood as reconciling the two approaches.     

Age Differences in Variables Affecting Motor Inhibition

This study's purpose was to analyze the effects of aging on motor control, with a specific focus on analyzing the characteristics of motor inhibition failure. A continuous‐response task was conducted with 35 younger adults and 35 older adults, under several conditions and using two types of switches. The results indicated the following: (a) in older adults, response type and auditory stimuli strongly affected motor inhibition failure, and (b) in younger adults, motor inhibition failures rarely occurred. When they did occur, they were strongly affected by factors directing visual stimuli. These results suggest age‐related differences in variables that affect motor inhibition, and that movement and the associated nervous excitation might strongly affect motor inhibition in older adults.     

Subtle Motor Findings During Recovery from Pediatric Traumatic Brain Injury: A Preliminary Report

Pediatric traumatic brain injury (TBI) is a heterogeneous condition, varying in both severity and sequelae. The long-term motor deficits following severe TBI requiring inpatient rehabilitation are better established than those following milder forms of TBI. The authors examined motor performance 2 and 12 months postinjury in children without overt motor impairment using standard measures of upper limb function and the Physical and Neurological Examination for Subtle Signs (PANESS). The PANESS was sensitive to differences between children with TBI and uninjured children as well as to changes in children with TBI over time. These data suggest that subtle motor deficits are present after milder forms of TBI and, particularly those related to balance and gait, may persist even 12 months postinjury.     

Remote Limb Ischemic Conditioning at Two Cuff Inflation Pressures Yields Learning Enhancements in Healthy Adults

The authors tested whether 2 doses of remote limb ischemic conditioning (RLIC), induced via blood pressure cuff inflation, enhanced motor and cognitive learning to an equal extent, and explored a panel of blood biomarkers of RLIC. Thirty-two young adults were randomized to 3 groups and underwent a 7-day protocol of RLIC/sham followed by motor and cognitive training, with follow-up. Both RLIC groups had greater motor learning and a trend toward greater cognitive learning compared with the sham group. RLIC at the lower inflation pressure was as effective as RLIC with the higher inflation pressure. No significant candidate blood biomarkers were found. RLIC could be a well-tolerated method to enhance learning and improve rehabilitation outcomes in people with neurological conditions.     

Decline of Hip Joint Movement Relates to Overestimation of Maximum Forward Reach in Elderly Persons

The authors aimed to characterize age-related changes in the performance of maximum reach and identify kinematic parameters that explain the age-related discrepancy between perceived and actual maximum reach distance. Maximum reach was evaluated in 22 younger women (21.3 years old) and 20 older women (81.2 years old). Both the perceived and actual maximum forward reach and forward excursion of the center of pressure was shorter in older women. Older women also overestimated their maximum reach distance to a greater extent. Decline of movement at the hip joint specifically correlated with both the maximum distance and the overestimation. Based on these results, decline of hip control may be a primary factor for the age-related retardation of perceived and actual maximum reach.     

The Impact of Family Unification Housing Vouchers on Child Welfare Outcomes

This study addresses whether providing housing vouchers through the Family Unification Program (FUP) to families involved in the child welfare system reduces child maltreatment and the need for child welfare services. The study uses child welfare administrative data on 326 children in Portland, Oregon, and 502 children in San Diego, California from the point at which their families were referred to the program through 18 months post‐referral. Using a quasi‐experimental waitlist comparison design, probit regressions show little impact of FUP on preventing child removal from home, but some positive impact on reunification among children already placed out of home. Hazard estimations show receipt of FUP speeds up child welfare case closure. Impacts on new reports of abuse and neglect are mixed, but point toward reduced reports. Low rates of removal among intact comparison families and high rates of reunification for children in out‐of‐home care suggest poor targeting of housing resources. Housing vouchers are being given to families not bearing the risks the program is intended to address. The presence of some positive findings suggests that housing vouchers might help reduce child welfare involvement if better targeting were practiced by child welfare agencies.
