The Effect of Erroneous Knowledge of Results on Skill Acquisition when Augmented Information is Redundant

Even though it can be shown that verbal knowledge of results (KR) is redundant with sensory feedback for learning certain motor skills, such findings do not eliminate the possibility that when KR is available it influences underlying learning processes. In order to examine the function of KR more closely, two experiments were designed in which the subjects received conflicting information about their own sensory feedback and the KR presented by the experimenter. In Experiment 1, two erroneous-KR groups, a correct-KR group, and a no-KR group performed 150 practice trials on a simple anticipation timing task and then performed three no-KR retention tests of 30 trials each following intervals of 10 minutes, 1 week, and 1 month. The results supported previous findings that providing correct KR is redundant in anticipation tasks. However, learning was influenced by KR as subjects performed according to the erroneous KR information, thereby ignoring their sensory feedback even after a 1-month interval. In Experiment 2, subjects practised a more complex striking response for the anticipation task for 75 trials and then performed no-KR retention trials either immediately, or 1 day or 1 week later. One of the groups received erroneous KR after 50 practice trials with correct KR. The results confirmed and extended those from Experiment 1, as erroneous KR, even after initial practice with correct KR, influenced retention performance. These results indicate that although KR provides information that is not needed to learn anticipation timing skills, this augmented verbal information is a dominant source of information that influences underlying cognitive processes involved in learning motor skills.     

It's a Wonderful Life: Reflections on Wittgenstein's Last Words

On his deathbed, Wittgenstein is reported to have said, upon hearing that his friends were coming for a visit, “Tell them I've had a wonderful life.” Malcolm found this puzzling, given that Wittgenstein seemed to be fiercely unhappy. I find my way into these words against the backdrop of the Hollywood film It's a Wonderful Life and Wittgenstein's famous remark, to wit, “Man has to awaken to wonder . . . Science is a way of sending him to sleep again.” Along the way I discuss Plato's praise of wonder, Nietzsche's attack on science, and Kierkegaard's remark about finding the sublime in the pedestrian. I conclude that Wittgenstein did have a wonderful life insofar as he was fully awake to wonder, what I call the wonder of our words.     

The Mobilizing Effect of Right‐Wing Ideological Climates: Cross‐Level Interaction Effects on Different Types of Outgroup Attitudes

The present research investigated a multilevel person‐context interactionist framework for the relationship between right‐wing ideologies and prejudice across two large, representative samples (Study 1: European Social Survey: N = 56,752; Study 2: World Values Survey: N = 74,042). Across three different operationalizations of right‐wing ideology, two contextual levels (regional and national) of right‐wing climate, and three types of outgroup attitudes (i.e., age‐, ethnicity‐, and gender‐based), the analyses consistently revealed cross‐level interactions, showing a strong association between right‐wing attitudes and negative outgroup attitudes at the individual level in contexts with a low right‐wing climate, whereas this relationship is weaker and often even absent in contexts with a high right‐wing climate. These cross‐level interactions remained significant after controlling for statistical artefacts (i.e., restriction of range and outliers). The authors propose norm setting as the mobilizing mechanism through which a right‐wing climate develops and curbs the influence of individual right‐wing social‐ideological attitudes on outgroup attitudes.     

Multisystemic therapy for young offenders: families' experiences of therapeutic processes and outcomes

Multisystemic Therapy (MST) has been found to be effective in reducing youth antisocial behavior, but little is known about the process and impact of MST from the perspective of families themselves. This qualitative study explored parents' and young people's experiences of MST, focusing on aspects of the intervention that promoted or limited change. Thirty-seven semistructured interviews were conducted with a consecutive sample of 21 families (21 parent interviews, 16 young people) who had participated in a randomized controlled trial of MST for young offenders in the United Kingdom. Thematic analysis yielded 10 themes, organized into two domains: (a) engagement in MST and initial processes of change captures the central importance of the therapeutic relationship and the MST engagement model in families' positive experiences of MST; and (b) outcomes are complex reflects the range of positive outcomes reported (notably increased parental confidence and skills, improved family relationships, a return to education, and greater reflection and aspiration on the part of the young person) and mixed behavior outcomes. Even when the young person had reoffended, respondents indicated a range of other benefits for the family. The findings support the MST theory of change as well as point to some outcomes not usually measured in MST outcome studies. They also suggest some adaptations that may increase the impact of the intervention, including more attention to the influence of deviant peers, and ongoing support for families struggling to maintain strategies beyond the prescribed treatment period.     

Diversity is what you want it to be: how social-dominance motives affect construals of diversity

We propose that diversity is a malleable concept capable of being used either to attenuate or to enhance racial inequality. The research reported here suggests that when people are exposed to ambiguous information concerning an organization's diversity, they construe diversity in a manner consistent with their social-dominance motives. Specifically, anti-egalitarian individuals broaden their construal of diversity to include nonracial (i.e., occupational) heterogeneity when an organization's racial heterogeneity is low. By contrast, egalitarian individuals broaden their construal of diversity to include nonracial heterogeneity when an organization's racial heterogeneity is high. The inclusion of occupational heterogeneity in perceptions of diversity allows people across the spectrum of social-dominance orientation to justify their support for or opposition to hierarchy-attenuating affirmative-action policies. Our findings suggest that diversity may not have a fixed meaning and that, without a specific delineation of what the concept means in particular contexts, people may construe diversity in a manner consistent with their social motivations.     

Impulse Control Disorders in Parkinson’s Disease: A Psychosocial Perspective

Parkinson's disease (PD) is a progressive neurodegenerative disease primarily characterised by motor symptoms. However, another feature of PD which is receiving increasing attention is the phenomenon of impulse control disorders (ICDs), such as pathological gambling. To date, research into ICDs in PD has centred on a biomedical model of cause, related to the effects of dopamine replacement therapy. However, there are several areas of discrepancy in the current biomedical account of ICDs in PD. In addition, we argue that social and psychological factors also need to be considered to achieve a more complete understanding of the phenomenon. We present a novel conceptual model which combines biomedical and psychosocial factors in the genesis of ICDs in PD and use the model to identify a number of potential treatment intervention points and to highlight important outstanding questions concerning the inter-relationship between psychosocial and biomedical factors in the genesis of ICDs in PD.
