Maternal Negativity and Children's Externalizing Behavior

Maternal negativity in parent-child interactions related to both the presence and persistence of child externalizing behavior problems. We examined how behavior of 120 mothers and their children in an interaction task at preschool related to assessments of child behavior problems at preschool, first grade, and third grade. At preschool and first-grade, children were assigned to three groups: comparison, moderate externalizing, and pervasive externalizing; at both timepoints the pervasive externalizing group had greater maternal negativity assessed at preschool. Maternal negativity was predicted, beyond the child's disruptive behavior in the task, by two variables: mother's perception of low spousal agreement and support related to child problems and depression. At third grade, child symptoms and diagnoses of ADHD and ODD were predicted by mothers' commands and repeat commands, though not negativity, in the preschool interaction task. Implications of these findings for early family intervention are discussed.     

Predicting vertical ground reaction force during running using novel piezoresponsive sensors and accelerometry

ABSTRACT

Running is a common exercise with numerous health benefits. Vertical ground reaction force (vGRF) influences running injury risk and running performance. Measurement of vGRF during running is now primarily constrained to a laboratory setting. The purpose of this study was to evaluate a new approach to measuring vGRF during running. This approach can be used outside of the laboratory and involves running shoes instrumented with novel piezoresponsive sensors and a standard accelerometer. Thirty-one individuals ran at three different speeds on a force-instrumented treadmill while wearing the instrumented running shoes. vGRF was predicted using data collected from the instrumented shoes, and predicted vGRF were compared to vGRF measured via the treadmill. Per cent error of the resulting predictions varied depending upon the predicted vGRF characteristic. Per cent error was relatively low for predicted vGRF impulse (2–7%), active peak vGRF (3–7%), and ground contact time (3–6%), but relatively high for predicted vGRF load rates (22–29%). These errors should decrease with future iterations of the instrumented shoes and collection of additional data from a more diverse sample. The novel technology described herein might become a feasible way to collect large amounts of vGRF data outside of the traditional biomechanics laboratory.     

Gender,Gender Role Identity,and Type of Relationship as Predictors of Relationship Behavior and Beliefs in College Students

The authors explored the relationship of gender, gender role identity, and type of relationship—same‐sex friendship, cross‐sex friendship, or romantic relationship—to relationship behaviors and beliefs among 429 college students. They discuss implications for individual and group counseling, consultation, and primary prevention on college campuses.

Clinical Competencies Specific to Family‐Based Therapy

Research has indicated that traditional office‐based family therapy services are not always effective with at‐risk families and that there is an increasing trend toward home‐based delivered services (W. Snyder & E. McCollum, 1999). In this qualitative study, the author explored experienced home‐based family therapists' perceptions of the competencies most salient to the provision of family‐based therapy. Several themes emerged from this study. The author presents 2 central themes: joining—including joining with the family, the family's community, and school personnel—and bridging the gap between academia and current community‐based programs.     

The role of a vertical reference point in changing gait regulation in cricket run-ups

The need to identify information sources which facilitate a functional coupling of perception and action in representative practice contexts is an important challenge for sport scientists and coaches. The current study investigated the role of visual information in regulating athlete gait behaviours during a locomotor pointing task in cricket. Integration of experiential knowledge of elite coaches and theoretical understanding from previous empirical research led us to investigate whether the presence of an umpire would act as a vertical informational constraint that could constrain the emergent coordination tendencies of cricket bowlers’ run-up patterns. To test this idea, umpire presence was manipulated during run-ups of 10 elite medium-fast bowlers. As hypothesised, removal of the umpire from the performance environment did not result in an inability to regulate gait to intercept a target, however, the absence of this informational constraint resulted in the emergence of different movement patterns in participant run-ups. Significantly lower standard deviation values of heel-to-crease distances were observed in the umpire condition at multiple steps, compared to performance in the no-umpire condition. Manipulation of this informational constraint altered gait regulation of participants, offering a mechanism to understand how perception–action couplings can be varied during performance in locomotor pointing tasks in sport.     

The impact of strategy instruction and timing of estimates on low and high working-memory capacity readers' absolute monitoring accuracy

Working-memory capacity, strategy instruction, and timing of estimates were investigated for their effects on absolute monitoring accuracy, which is the difference between estimated and actual reading comprehension test performance. Participants read two expository texts under one of two randomly assigned reading strategy instruction conditions (an explanation strategy versus no strategy). Next, readers estimated comprehension test performance both immediately and after a delay. Readers' estimations were followed by the completion of a comprehension test, a postdiction of test performance, and a working-memory capacity task. The results showed that low working-memory capacity readers were generally more accurate than high working-memory capacity readers but were not affected by strategy instruction or timing of estimates. In contrast, high working-memory capacity readers were most accurate when instructed to use an explanation strategy and when estimates were made immediately. These results are described in the context of the increased processing hypothesis, which contends that more effortful processing during reading augments the availability of text concepts and, in turn, enhances absolute monitoring accuracy.     

A critical pedagogy of place: from gridlock to parallax 1

Differences of perspective, standpoint and subjectivity can help to enlarge the conceptual landscape of environmental education theory. Rejections of difference, on the other hand, can become an intolerance that narrows the scope of inquiry. This rejoinder argues that Bowers’ repeated rejections of critical pedagogy are based on a partial reading of the critical tradition, and that these critiques, including his current call to ‘avoid embracing’ a critical pedagogy of place, are unnecessarily dismissive and therefore counterproductive. Environmental education has benefited and will continue to benefit from the critical tradition of which critical pedagogy is a part. Relationships and/or antagonisms are constructed through human responses and interactions. Sameshima’s pedagogical theory of parallax is introduced as a way of seeing relationships between ideas that have been thought to be opposed. Moving toward relationship rather than rivalry, the rejoinder concludes by suggesting that Bowers’ and Freire’s criticality is actually more alike than different.
