Reducing Knowledge of Results about Relative versus Absolute Timing: Differential Effects on Learning

The purpose of the present experiment was to examine further earlier suggestions that a reduced relative frequency of knowledge of results (KR) can enhance the learning of generalized motor programs (GMPs) but at the same time degrade parameter learning, compared with giving KR after every trial (Wulf & Schmidt, 1989; Wulf, Schmidt, & Deubel, 1993). In contrast to these earlier studies, here KR was given separately for relative timing and absolute timing. Subjects practiced three movement patterns that required the same relative timing but different absolute movement times. KR was provided on 100% or 50% of the practice trials for relative timing or absolute timing, respectively. In retention and transfer tests, the groups that had had 50% KR about relative timing demonstrated more effective learning of the relative-timing structure, that is, GMP learning, than the groups that had had 100% KR about relative timing. The KR frequency had no effect on parameterization during retention; yet, when transfer to a task with a novel overall duration was required, the groups given 100% KR about absolute timing were more accurate in parameterization than the groups provided with 50% KR about absolute timing. Thus, the reduced relative KR frequency enhanced GMP learning but had no beneficial effect, or even a degrading effect, on parameter learning. The differential effects of a reduced KR frequency on the learning of relative timing and absolute timing also provide additional support for the dissociation of GMP and parameterization processes.     

Human values,legal regulation,and approval of homosexuality in Europe: A cross‐country comparison

Although research has revealed a trend toward liberalization of attitudes toward homosexuality in Western countries, acceptance of homosexuality differs remarkably among individuals and across countries. We examine the roles of individual value priorities and of national laws regarding homosexuality and the interaction between them in explaining approval of homosexuality. Data are drawn from the European Social Survey and include representative national samples of 27 European countries in 2010. As hypothesized, individuals who prioritized openness to change and universalism values approved of homosexuality more, whereas those who prioritized conservation and power values exhibited more disapproval. Approval was greater in countries whose laws regarding homosexuality were more progressive. In addition, legal regulation of homosexuality moderated the associations of individual value priorities. In countries with more progressive laws, both the positive effect of openness to change values and the negative effect of conservation values on approval of homosexuality were weaker. However, the positive effect of universalism values and the negative effect of power values did not vary as a function of national laws regarding homosexuality.

Prognostische Validität des Level of Service Inventory-Revised

This study examined the validity of the level of service inventory-revised (LSI-R) for a sample of young violent offenders in Germany (N?=199) who were sentenced to more than 2 years imprisonment using a retrospective study design. Offenders with a migrant background from a predominantly Muslim country were compared to native German offenders. Both groups were similar regarding age, criminal history, socioeconomic status, education, current risk of subsequent offending and recidivism. For the group of young offenders with a migrant background from a predominantly Muslim country (n?=85), the LSI-R failed to validly predict problem behavior during imprisonment as well as to validly predict recidivism within 2 and 5 years after release from prison. In contrast, for native German offenders (n?=114) the LSI-R performed satisfactorily in predicting problematic behavior during imprisonment and achieved a moderate to high level of predictive power in predicting recidivism after release from prison. These findings stress the necessity for research on influencing factors, developmental dynamics and prognosis among young violent offenders with a migrant background from a predominantly Muslim culture.     

The Association Between Therapeutic Alliance and Treatment Outcomes in a Group Triple P Intervention

A growing literature has examined the association between therapeutic alliance and treatment outcomes in child therapy. Few studies, however, have specifically investigated the role of therapeutic alliance within evidence-based parenting programs for children with externalizing behavioural difficulties. The current study prospectively collected measures of therapeutic alliance for 117 families completing a Triple P parenting program in a community children’s mental health center. Higher levels of mother and father rated therapeutic alliance were associated with greater gains in parenting skills and parental sense of competence. Parental rated therapeutic alliance was also associated with greater improvements in child conduct problems for mothers, but not fathers. However, therapist ratings of therapeutic alliance had limited associations with treatment improvement. The implications of the findings for clinical practice are discussed.     

COVID-19 Impact Battery: Development and Validation

In addition to impacting the physical health of millions of Americans, the novel-coronavirus (COVID-19) pandemic is a significant psychological stressor due to both the threat of the illness itself and the mitigation strategies used to contain the spread. To facilitate understanding of the impact of COVID-19, validated measures are needed. Using a stepwise procedure in line with best-practice measurement procedures, the current report summarizes the procedures employed to create the COVID-19 Impact Battery (CIB). Two independent samples recruited via Amazon Mechanical Turk (N?=?175, N?=?642) and a third community sample (N?=?259) were used for reliability and validity testing. Validation procedures yielded a battery consisting of three scales assessing COVID-19 related behaviors, worry, and disability. The behaviors scale contains three subscales assessing stockpiling, cleaning, and avoidance. The worry subscale also contains three subscales assessing health, financial and catastrophic concerns. In addition, we created a short version of the battery (CIB-S) to allow for more flexibility in data collection. In summary, we have provided reliability and validity information for the CIB and CIB-S, demonstrating that these measures can facilitate evaluation of the broad impact of COVID-19 on mental health functioning.

     

Young children attribute normativity to novel actions without pedagogy or normative language

Young children interpret some acts performed by adults as normatively governed, that is, as capable of being performed either rightly or wrongly. In previous experiments, children have made this interpretation when adults introduced them to novel acts with normative language (e.g. 'this is the way it goes'), along with pedagogical cues signaling culturally important information, and with social-pragmatic marking that this action is a token of a familiar type. In the current experiment, we exposed children to novel actions with no normative language, and we systematically varied pedagogical and social-pragmatic cues in an attempt to identify which of them, if either, would lead children to normative interpretations. We found that young 3-year-old children inferred normativity without any normative language and without any pedagogical cues. The only cue they used was adult social-pragmatic marking of the action as familiar, as if it were a token of a well-known type (as opposed to performing it, as if inventing it on the spot). These results suggest that - in the absence of explicit normative language - young children interpret adult actions as normatively governed based mainly on the intentionality (perhaps signaling conventionality) with which they are performed.     

Influencing Learning States to Enhance Trainee Motivation and Improve Training Transfer

Purpose  

This study examines a pretraining intervention to enhance transfer of training. The learning-state analog of locus of control was the target for intervention designed to impact motivation to learn which in turn would affect knowledge acquisition and the amount of posttraining practice.
