Performance-based adaptive schedules enhance motor learning

Although investigators have shown that random scheduling of several tasks enhances learning more than blocked scheduling does, the advantages of random scheduling may be limited because it does not take into account the nominal difficulty of each task, the difference in difficulty between tasks, and the skill level of the learner in that type of schedule. The authors propose 2 new algorithms for adaptively determining the nominal difficulty and the number of trials for each task on the basis of both current and delayed performance of the learner (N = 48). The authors tested the adaptive algorithms in a 2 x 2 factorial design, and they show that the algorithms outperform random scheduling when performance is measured on a delayed retention test.     

Living the Paradox: Female Athletes Negotiate Femininity and Muscularity

Sportswomen live in 2 cultures: the sport culture that is inherently masculine and the larger social culture where femininity is celebrated for women. In this investigation, which was grounded in feminist cultural studies, we pursued the research question: how do female athletes negotiate and reconcile the social expectations surrounding femininity with athleticism? Twenty-one female college athletes participated in focus group interviews about body image and perceptions of muscularity and femininity. Data analysis resulted in 3 higher order themes: the influence of hegemonic femininity, athlete as other, and physicality. These athletes expressed that being feminine contrasted with being athletic. They further conveyed that as athletes, they were marginalized and perceived as different from “normal” women. Yet, they also were proud of their strong, developed bodies and expressed feelings of empowerment that generalized beyond the sport context.     

Cognitive Remediation in Schizophrenia

Cognitive deficits are routinely evident in schizophrenia, and are of sufficient magnitude to influence functional outcomes in work, social functioning and illness management. Cognitive remediation is an evidenced-based non-pharmacological treatment for the neurocognitive deficits seen in schizophrenia. Narrowly defined, cognitive remediation is a set of cognitive drills or compensatory interventions designed to enhance cognitive functioning, but from the vantage of the psychiatric rehabilitation field, cognitive remediation is a therapy which engages the patient in learning activities that enhance the neurocognitive skills relevant to their chosen recovery goals. Cognitive remediation programs vary in the extent to which they reflect these narrow or broader perspectives but six meta-analytic studies report moderate range effect sizes on cognitive test performance, and daily functioning. Reciprocal interactions between baseline ability level, the type of instructional techniques used, and motivation provide some explanatory power for the heterogeneity in patient response to cognitive remediation.     

Acquisition of hierarchical reactive skills in a unified cognitive architecture

In this paper, we review Icarus, a cognitive architecture that utilizes hierarchical skills and concepts for reactive execution in physical environments. In addition, we present two extensions to the framework. The first involves the incorporation of means-ends analysis, which lets the system compose known skills to solve novel problems. The second involves the storage of new skills that are based on successful means-ends traces. We report experimental studies of these mechanisms on three distinct domains. Our results suggest that the two methods interact to acquire useful skill hierarchies that generalize well and that reduce the effort required to handle new tasks. We conclude with a discussion of related work on learning and prospects for additional research, including extending the framework to cover developmental phenomena.     

Effect of Socioeconomic Status on the Linkage Between Suicidal Ideation and Suicide Attempts

Previous suicide attempts are a leading risk factor for completed suicide. To identify specific characteristics of those at high risk for attempts, we investigated associations with socioeconomic status (SES). Data from the 2013 Korean Community Health Survey (KCHS) included adults who reported suicidal ideation (N = 220,245). Attempts in the past 12 months were assessed. Associations of demographic, socioeconomic, and suicide‐related behavioral factors were analyzed using multiple logistic regression. Among those with suicidal ideation, 862 (3.9%) had attempted suicide. After stratification by age and gender, results showed that low education and unemployed young adult men and women had significantly higher rates of attempts. The lowest income level was associated with significantly higher rates of attempts in only young adult women. Among those with the lowest and highest income, the association between ideation and attempts was attenuated, whereas it was enhanced among other income groups.     

Flow,Diversity, Form,and Influence of Political Talk in Social‐Media‐Based Public Forums

By investigating social‐media‐based public forums and using network and content analyses, this study explores how political discussions flow, how diverse they are, and what forms of political discussions are influential. The results suggest that the flow of political discussions is not notably centralized and cliquish. Participants refer primarily to the remarks of like‐minded fellow citizens. Political discussions are more emotional than cognitive and express more anger than anxiety, but it appears that cognitive discussions are more influential than emotional ones. Among cognitive components, assertive and strong discussions have greater influence than analytical ones. These results have implications for the practice of citizenship and the theory of selective exposure as well as for future directions in political communication research.     

Body Hair Removal: The ‘Mundane’ Production of Normative Femininity

Although womens body hair removal is strongly normative across contemporary Western cultures, only two studies of mundane depilation have been published, and they were based on data from the US (Basow, 1991) and Australia (Tiggemann & Kenyon, 1998), respectively. The present survey, comprised of a sample of 678 women, extends this work. We investigated UK practices, a wider array of body regions and removal methods, and the relationship between depilation and age. Over 99% of participants reported removing some hair, most commonly from the underarms, legs, pubic area, and eyebrows. Shaving and plucking were the most common removal methods. Significant relationships between age and leg, pubic, and facial depilation were found. Results document the normativity of hair removal, and we argue that hair removal is part of the taken-for-granted work of producing an acceptable femininity.     

Preschool language exposure and use: A comparison study of dual-language learners and English monolingual children

This study explored the language experiences of dual language learners (DLL; n = 19) and English monolinguals (EM; n = 13) in preschool classrooms where English is the primary language of instruction and many home languages are present. Using the Language ENvironment Analysis™ system as a primary tool, we quantitatively analysed an average of 34 hours of recordings collected over 5–8 days for each participating child (M_age = 52 months) in six classrooms. Results showed that, during a typical preschool day, DLLs spoke as much as EMs but received less adult talk overall and had more 5-min segments with zero adult–child conversations than their EM peers. Follow-up analyses revealed that teachers generally talked less when children initiated the conversations than when adults initiated the conversations, and this pattern was particularly evident for DLLs. Study implications and future research are discussed.
