Effects of A Dual-Task Intervention in Postural Control and Cognitive Performance in Adolescents

Abstract

The aim was to assess dual- versus single-task training for motor performance and cognitive performance in adolescents. Two experiments were performed. In the first, 30 adolescents were randomized to three groups to determine the effect of dual-task difficulty on postural control: α-scaling and root mean square (RMS). In the second, 20 adolescents were randomized to two groups to determine the effect of dual-task practice to improve working memory. RMS in the post-test was lower than the pre-test in both dual-task groups, while α-scaling was lower in post-test than pre-test only in the high-difficulty dual-task group. A practice effect was observed on the percentage of correct answers only in the dual-task group (p?=?0.035). Thus, dual-task training could enhance motor and cognitive performance more than single-task training.     

亲社会行为的认知过程及脑神经基础

亲社会行为是指有利于他人和社会的行为,包括合作、分享、助人、安慰等。亲社会行为产生主要涉及几种认知过程:对他人行为和情绪的注意、社会信息加工、对结果的奖赏预期、社会规范表征、自我控制、以及社会信息整合与价值计算等。基于这些认知过程,研究发现,亲社会行为主要与前脑岛和前扣带回、默认网络背内侧子系统、奖赏系统以及前额叶皮层等神经区域有关,因此提出亲社会行为共同的认知-脑神经回路。未来可以对亲社会行为脑神经基础的共性、功能连接以及跨文化研究等方面做进一步探讨。     

Self-Regulation in the Classroom: A Perspective on Assessment and Intervention

Il n’y a pas de définition simple et univoque du concept d’apprentissage autorégulé. Des théoriciens de psychologie de l’éducation ont réduit l’éventail des aptitudes des élèves à s’autoréguler en se focalisant sur le versant scolaire de l’éducation, à savoir l’acquisition des connaissances et les objectifs de réussite. Toutefois, le monde complexe de l’étude en classe engendre une situation où différents buts entrent en concurrence aux yeux des élèves. Le modèle d’autorégulation à double processus de Bookaerts montre que les deux objectifs que sont l’étude et le bien‐être interagissent. Nous estimons que lorsque les élèves ont accès à des stratégies autonomes bien au point se traduisant par de bonnes habitudes de travail, ils ont une plus grande probabilité de se motiver pour les études et de sauvegarder leur bien‐être quand une source de stress bloque l’apprentissage. There is no simple and straightforward definition of the construct of self‐regulated learning. Theorists in educational psychology have narrowed the scope of students’ capability to self‐regulate through a focus on the academic side of education, namely on learning and achievement goals. However, the messy world of classroom learning creates a situation in which different goals compete for students’ attention. Boekaerts’ dual processing self‐regulation model describes how learning goals interact with well‐being goals. We propose that when students have access to well‐refined volitional strategies manifested as good work habits, they are more likely to invest effort in learning and get off the well‐being track when a stressor blocks learning. Shifting definitions of SRL have led to changing measurement procedures; researchers moved away from decontextualised measures of SRL to domain‐specific measures and then on to context‐sensitive measures. The validity and reliability of the first generation of SR assessment has been limited and several issues remain. Recently, researchers have designed assessment packages including new instruments that better capture self‐regulation as a process (including for example traces of mental events, situational manipulations, and records of student work strategies). A combination of instruments is preferable over a single instrument for assessing self‐regulation as a process and the effects of interventions to improve students’ self‐regulatory capacity. At present, many sound SRL interventions exist and some general lessons can be learned about classroom intervention research.     

Adolescent Self-Esteem and Cognitive Skills Training: A School-Based Intervention

We developed and evaluated a school-based psychosocial prevention program for adolescents, focusing on self-esteem, negative cognitive processes, and peer isolation. Fifty-one tenth-grade students between the ages of 13–16 were recruited and randomly allocated to one of three groups; Social Cognitive Training group (SCT), Attention Placebo Comparison Group (APC) and a Waitlist Control group (WL). A pre-post design using two types of measures: specific measures of the target skills (self-esteem, self-statements) and impact measures (quality of peer relationships, acceptability of intervention for adolescents and teachers) evaluated the effectiveness and social validity of the intervention. Multivariate Analyses of Variance showed significant improvements on measures of target skills for the SCT group in contrast to the comparison conditions on reported self-esteem, and self statements, however mixed results were found on the impact measures. While the SCT group was rated as highly acceptable and useful by both adolescents and teachers, student self report ratings of quality of peer relationships showed little change across the study period. We discussed our findings in terms of the effectiveness of group based cognitive interventions in developing adolescent self-esteem and social competence, and the ecological validity of implementing programs within naturalistic settings.     

A Study of Prejudice Toward University Student-Athletes

The attitudes of 293 first-time entering students at a large, public eastern university were measured using the revised Situational Attitude Scale (SAS) Student-Athlete. The findings suggested that freshman students perceived student-athletes negatively in situations dealing with academic competence. The contention was made to include the student-athlete culture as one susceptible to prejudice and discrimination. Student-athletes should be educated to the “isms” they may be facing from their peers in the classroom and on the campus. These results also indicated the need to include the student-athlete culture when engaging in “ism” reduction efforts with members of the campus community. Se midieron las actitudes de 293 estudiantes del primer año en una universidad pública grande en el este, usando el Revised Situational Attitude Scale (SAS) Student-Athlete. Los resultados sugieren que los estudiantes del primer año perciben a los estudiantes-atletas de una manera negativa en situaciones que tienen que ver con la competencia académica. Se discutió la visión de la cultura estudiante-atleta como susceptible de prejuicio y discriminación. Se debe educar a los estudiantes-atletas sobre los “-ismos” que ellos podrán encontrar en el aula y en el campus. Estos resultados también indican la necesidad de incluir la cultura estudiante-atleta cuando los miembros de una comunidad universitaria intentan reducir los “-ismos.”     

Enhancing Classroom Performance: A Review of Reinforcement Schedules

During the past decade the application of elementary principles of behavior have become a standard in the classroom teacher's repertoire of behavior change strategies. Unfortunately, the application of more advanced principles of behavior derived through basic behavioral research lies as an untapped resource for classroom teachers. Nowhere is this more apparent than in the use of systematic procedures to deliver reinforcers to enhance academic performance. In this paper we provide educators with information on the use of reinforcement schedules in academic settings. Various schedules of reinforcement are presented along with examples of their application in applied settings.     

Cognitive Behaviour Therapy: A Critical Evaluation of its Theoretical-Empirical Bases and Therapeutic Efficacy

This paper presents a summarizing overview of the present conceptual, empirical, and practical status of the recent “cognitive trend” in behaviour therapy. The theoretical and practical similarities and differences of the three most influential cognitive-behavioural approaches are presented and some empirical evidence of their theoretical bases is critically examined. Finally, the therapeutic efficacy of these approaches is briefly reviewed.     

A Cognitive Behavioral Adherence Intervention for Adolescents with Type 1 Diabetes

This study examined the impact of a cognitive behavioral intervention for nonadherent adolescents with type 1 diabetes. Six youths having problems following the diabetes regimen received training in cognitive restructuring and problem solving during individual sessions. A multiple baseline design across participants was used. Treatment effectiveness was assessed through 24-hr recall adherence interviews with adolescents and frequency of testing data was downloaded from glucose meters. Data was also collected for diabetes-specific stress. Five youths displayed improvement on at least one self-care behavior. Furthermore, the results suggest that the cognitive behavioral intervention was effective in diminishing diabetes-related stress in two participants. Cognitive behavioral interventions show promise for increasing self-care behaviors among nonadherent youths with type 1 diabetes. However, individual youths varied in their response to treatment. Further research is needed in developing procedures to better meet the needs of youths, improve youth participation, and enhance treatment effectiveness.

I only regret that the strict space limitation imposed by the editor restricts my response to points on which my paper was unclear, and to a few important substantive issues. It would have been very satisfying to explore the many constructive and highly intriguing insights contained in the commentators' contributions.     

The Influence of a Visually-Rich Surrounding Environment in Visuospatial Cognitive Performance: A Study with Adolescents

ABSTRACT

Adolescence is a developmental period characterized by a complex maturation process of various cognitive abilities. Cognitive control, which includes response inhibition and working memory, is one of them. A typical study on response inhibition to visual stimuli presents distractors and targets on the same display (e.g., the computer screen). However, in most daily activities, the potential for distraction exists in the individuals’ surrounding environment. This study proposes an alternative experimental paradigm to investigate whether a high- vs. a low-load visual surrounding environment influences adolescents’ visuospatial performance. Sixty-four adolescents (aged 13–17 years) participated in two experimental sessions (one in a high-load and the other in a low-load visual surrounding environment) in which they responded to four visuospatial cognitive tasks (attention and memory). Overall, the results revealed lower performance when the tasks were performed in the high-load environment (e.g., fewer hits and correct responses, and more false alarms and errors). These results suggest that more attention should be devoted to the potential effect of the external environment in adolescents’ everyday activities. We discuss various areas to which these data might be of relevance and make suggestions for future directions of the proposed procedure.     

A Practice-Specificity-Based Model of Arousal for Achieving Peak Performance

The authors propose a practice-specificity-based model of arousal for achieving peak performance. The study included 37 healthy male physical education students whom they randomly assigned to a high-arousal (n = 19) or low-arousal group (n = 18). To manipulate participants' level of arousal, the authors used motivational techniques. They used heart rate and the Sport Competition Anxiety Test (R. Martens, 1977) to measure the level of arousal that participants achieved. At the determined and given arousal state, the 2 groups performed the task (basketball free throws) for 18 sessions. Both groups performed a retention test at the 2 arousal levels immediately after the last exercise session, in the posttest, and after 10 days. Results showed that both groups learned the task similarly and achieved their peak performance at their experienced arousal level. When tested at an arousal level that differed from the one that they experienced throughout practice sessions, participants' performance had deteriorated significantly. Performance of the task seemed to have integrated with the arousal level of the participants during the task learning. The findings of this study suggest a practice-specificity-based explanation for achieving peak performance.     

A Brief Social Skills Intervention to Reduce Challenging Classroom Behavior

Social skills instruction has been recommended as a way of improving behavioral and social outcomes for students with emotional and behavioral disorders (EBD). A brief social skills intervention (Stop and Think (Knoff in The stop & think social skills program, Sopris West, Longmont, CO, 2001) was used to extend the current literature base for students with EBD. A multiple-baseline across classrooms design was used to examine negative social behavior of five participants attending a self-contained school setting for students with challenging behavior. The primary intervention components included: (a) teach, (b) model, (c) role play, and (d) performance feedback. Specific social skills addressed in intervention were listening, using nice talk, accepting consequences, ignoring others, and following directions. Participants were taught to use a 5-step process for each social skill: (1) stop and think, (2) identify good and bad choices, (3) identify steps to performing the good choice, (4) implement steps, and (5) reflect on the good choice you made. Results indicated students benefitted from 12 sessions of explicit social skills instruction as evidenced by decreases in negative social behavior. Social behavior improvements maintained during 2-week follow-up observations. Decreasing negative social behaviors is important in improving general social and behavioral outcomes as well as demonstrating growth toward being prepared to transition back to less restrictive environments. Limitations, recommendations for future research, and practice implications are discussed.

Cognitive Behavioral Therapy for HIV-Negative Heterosexual Meth Users: The FASTLANE II Intervention

The purpose of this paper is to provide clinicians with a theoretical roadmap and practical toolkit for the FASTLANE II intervention, a 9-session behavior change intervention for HIV-negative meth-using heterosexual men and women that simultaneously targets depressive symptoms, meth use, and sexual risk behavior. The intervention was grounded in cognitive behavioral therapy (CBT), social cognitive theory (SCT), and the theory of reasoned action (TRA), and utilized a variety of cognitive and behavioral techniques. Examples of those techniques are provided, as well how those techniques map onto core theoretical elements of CBT, SCT, and TRA. We present three case studies with sample counseling session dialogue. Techniques and skills from FASTLANE II may be of use to clinicians interested in targeting depression, meth use, and high-risk sexual behavior.     

The Efficacy of Cognitive Intervention in Mild Cognitive Impairment (MCI): a Meta-Analysis of Outcomes on Neuropsychological Measures

Cognitive training in MCI may stimulate pre-existing neural reserves or recruit neural circuitry as “compensatory scaffolding” prompting neuroplastic reorganization to meet task demands (Reuter-Lorenz & Park, 2014). However, existing systematic reviews and meta-analytic studies exploring the benefits of cognitive interventions in MCI have been mixed. An updated examination regarding the efficacy of cognitive intervention in MCI is needed given improvements in adherence to MCI diagnostic criteria in subject selection, better defined interventions and strategies applied, increased use of neuropsychological measures pre- and post-intervention, as well as identification of moderator variables which may influence treatment. As such, this meta-analytic review was conducted to examine the efficacy of cognitive intervention in individuals diagnosed with mild cognitive impairment (MCI) versus MCI controls based on performance of neuropsychological outcome measures in randomized controlled trials (RCT). RCT studies published from January 1995 to June 2017 were obtained through source databases of MEDLINE-R, PubMed, Healthstar, Global Health, PSYCH-INFO, and Health and Psychological Instruments using search parameters for MCI diagnostic category (mild cognitive impairment, MCI, pre-Alzheimer’s disease, early cognitive decline, early onset Alzheimer’s disease, and preclinical Alzheimer’s disease) and the intervention or training conducted (intervention, training, stimulation, rehabilitation, or treatment). Other inclusion and exclusion criteria included subject selection based on established MCI criteria, RCT design in an outpatient setting, MCI controls (active or passive), and outcomes based on objective neuropsychological measures. From the 1199 abstracts identified, 26 articles met inclusion criteria for the meta-analyses completed across eleven (11) countries; 92.31% of which have been published within the past 7 years. A series of meta-analyses were performed to examine the effects of cognitive intervention by cognitive domain, type of training, and intervention content (cognitive domain targeted). We found significant, moderate effects for multicomponent training (Hedges’ g observed?=?0.398; CI [0.164, 0.631]; Z?=?3.337; p?=?0.001; Q?=?55.511; df?=?15; p?=?0.000; I ² ?=?72.978%; τ ² ?=?0.146) as well as multidomain-focused strategies (Hedges’ g?=?0.230; 95% CI [0.108, 0.352]; Z?=?3.692; p??< 0.001; Q?=?12.713; df?=?12; p?=?0.390; I ² ?=?5.612; τ ² ?=?0.003). The effects for other interventions explored by cognitive domain, training type, or intervention content were indeterminate due to concerns for heterogeneity, bias, and small cell sizes. In addition, subgroup and meta-regression analyses were conducted with the moderators of MCI category, mode of intervention, training type, intervention content, program duration (total hours), type of control group (active or passive), post-intervention follow-up assessment period, and control for repeat administration. We found significant overall effects for intervention content with memory focused interventions appearing to be more effective than multidomain approaches. There was no evidence of an influence on outcomes for the other covariates examined. Overall, these findings suggest individuals with MCI who received multicomponent training or interventions targeting multiple domains (including lifestyle changes) were apt to display an improvement on outcome measures of cognition post-intervention. As such, multicomponent and multidomain forms of intervention may prompt recruitment of alternate neural processes as well as support primary networks to meet task demands simultaneously. In addition, interventions with memory and multidomain forms of content appear to be particularly helpful, with memory-based approaches possibly being more effective than multidomain methods. Other factors, such as program duration, appear to have less of an influence on intervention outcomes. Given this, although the creation of new primary network paths appears strained in MCI, interventions with memory-based or multidomain forms of content may facilitate partial activation of compensatory scaffolding and neuroplastic reorganization. The positive benefit of memory-based strategies may also reflect transfer effects indicative of compensatory network activation and the multiple-pathways involved in memory processes. Limitations of this review are similar to other meta-analysis in MCI, including a modest number studies, small sample sizes, multiple forms of interventions and types of training applied (some overlapping), and, while greatly improved in our view, a large diversity of instruments used to measure outcome. This is apt to have contributed to the presence of heterogeneity and publication bias precluding a more definitive determination of the outcomes observed.     

The Personality Bases of Ideology: A One-Year Longitudinal Study

ABSTRACT

The cross-lagged effects of the Big-Five personality dimensions on Social Dominance Orientation (SDO) and Right-Wing Authoritarianism (RWA) were examined over 1 year (N = 112). Consistent with the Dual Process Cognitive-Motivational Model, SDO and RWA exhibited markedly different personality bases. Low Agreeableness and unexpectedly high Extraversion predicted change in the motivational goal for group-based dominance and superiority (SDO), whereas Openness to Experience predicted change in the motivational goal for social cohesion and collective security (RWA). Neuroticism and Conscientiousness did not predict change in SDO or RWA over time. These findings extend previous cross-sectional (correlational) research and indicate that key dimensions of personality (primarily Agreeableness and Openness to Experience) are an important temporal antecedent of the group-based motivational goals underlying individual differences in prejudice.
