An adaptive network model covering metacognition to control adaptation for multiple mental models

Learning processes can be described by adaptive mental (or neural) network models. If metacognition is used to regulate learning, the adaptation of the mental network becomes itself adaptive as well: second-order adaptation. In this paper, a second-order adaptive mental network model is introduced for metacognitive regulation of learning processes. The focus is on the role of multiple internal mental models, in particular, the case of visualisation to support learning of numerical or symbolic skills. The second-order adaptive network model is illustrated by a case scenario for the role of visualisation to support learning multiplication at the primary school.     

Counter-stereotypical impulsivity and violence among African American college men

The study examined the relationship between impulse control and violence in terms of past feelings and acts among African American males enrolled in Historically Black Colleges and Universities. Data were gathered from a sample of 1,874 male undergraduates in eleven colleges and universities with predominantly African-American students. Less than six percent were classified as impulsive, and even less than half of the impulsive males had past feelings and acts of violence. The study offers strategies for impulse control which may help to further minimize incidents of violence on the college campus.     

Towards autonomous artificial agents with an active self: Modeling sense of control in situated action

In this paper we present a computational modeling account of an active self in artificial agents. In particular we focus on how an agent can be equipped with a sense of control and how it arises in autonomous situated action and, in turn, influences action control. We argue that this requires laying out an embodied cognitive model that combines bottom-up processes (sensorimotor learning and fine-grained adaptation of control) with top-down processes (cognitive processes for strategy selection and decision-making). We present such a conceptual computational architecture based on principles of predictive processing and free energy minimization. Using this general model, we describe how a sense of control can form across the levels of a control hierarchy and how this can support action control in an unpredictable environment. We present an implementation of this model as well as first evaluations in a simulated task scenario, in which an autonomous agent has to cope with un-/predictable situations and experiences corresponding sense of control. We explore different model parameter settings that lead to different ways of combining low-level and high-level action control. The results show the importance of appropriately weighting information in situations where the need for low/high-level action control varies and they demonstrate how the sense of control can facilitate this.     

The impact of Wii Fit intervention on dynamic balance control in children with probable Developmental Coordination Disorder and balance problems

The aim of this study was to examine differences in the performance of children with probable Developmental Coordination Disorder (p-DCD) and balance problems (BP) and typical developing children (TD) on a Wii Fit task and to measure the effect on balance skills after a Wii Fit intervention.Twenty-eight children with BP and 20 TD-children participated in the study. Motor performance was assessed with the Movement Assessment Battery for Children (MABC2), three subtests of the Bruininks Oseretsky Test (BOT2): Bilateral Coordination, Balance and Running Speed & Agility, and a Wii Fit ski slalom test. The TD children and half of the children in the BP group were tested before and after a 6 weeks non-intervention period. All children with BP received 6 weeks of Wii Fit intervention (with games other than the ski game) and were tested before and afterwards.Children with BP were less proficient than TD children in playing the Wii Fit ski slalom game. Training with the Wii Fit improved their motor performance. The improvement was significantly larger after intervention than after a period of non-intervention. Therefore the change cannot solely be attributed to spontaneous development or test–retest effect. Nearly all children enjoyed participation during the 6 weeks of intervention. Our study shows that Wii Fit intervention is effective and is potentially a method to support treatment of (dynamic) balance control problems in children.     

The Goal Circuit Model: A Hierarchical Multi‐Route Model of the Acquisition and Control of Routine Sequential Action in Humans

Human control of action in routine situations involves a flexible interplay between (a) task‐dependent serial ordering constraints; (b) top‐down, or intentional, control processes; and (c) bottom‐up, or environmentally triggered, affordances. In addition, the interaction between these influences is modulated by learning mechanisms that, over time, appear to reduce the need for top‐down control processes while still allowing those processes to intervene at any point if necessary or if desired. We present a model of the acquisition and control of goal‐directed action that goes beyond existing models by operationalizing an interface between two putative systems—a routine and a non‐routine system—thereby demonstrating how explicitly represented goals can interact with the emergent task representations that develop through learning in the routine system. The gradual emergence of task representations offers an explanation for the transfer of control with experience from the non‐routine goal‐based system to the routine system. At the same time it allows action selection to be sensitive both to environmental triggers and to biasing from multiple levels within the goal system.     

控制感剥夺激发状态毅力：趋近动机的中介作用

采用概念判断任务,通过两个递进式实验探索控制感剥夺对状态毅力的影响并考察趋近动机在其中的作用。实验1主观报告结果显示：短时条件下,控制感剥夺组的状态毅力显著高于控制感维持组,尤其表现在努力持续性维度;长时条件下,两组差异不显著。实验2在此基础上加入行为指标结果显示：短时控制感剥夺通过高趋近动机对状态毅力产生影响。结果表明毅力是可塑的,突出表现在努力持续性上,该效应出现在个体经历短时控制感剥夺后。     

Bernstein’s levels of movement construction: A contemporary perspective

Explanation of how goal-directed movements are made manifest is the ultimate aim of the field classically referred to as “motor control”. Essential to the sought-after explanation is comprehension of the supporting functional architecture. Seven decades ago, the Russian physiologist and movement scientist Nikolai A. Bernstein proposed a hierarchical model to explain the construction of movements. In his model, the levels of the hierarchy share a common language (i.e., they are commensurate) and perform complementing functions to bring about dexterous movements. The science of the control and coordination of movement in the phylum Craniata has made considerable progress in the intervening seven decades. The contemporary body of knowledge about each of Bernstein’s hypothesized functional levels is both more detailed and more sophisticated. A natural consequence of this progress, however, is the relatively independent theoretical development of a given level from the other levels. In this essay, we revisit each level of Bernstein’s hierarchy from the joint perspectives of (a) the ecological approach to perception-action and (b) dynamical systems theory. We review a substantial and relevant body of literature produced in different areas of study that are accommodated by this ecological-dynamical version of Bernstein’s levels. Implications for the control and coordination of movement and the challenges to producing a unified theory are discussed.     

Stratégies de contrôle adaptatives au fil de l’âge adulte et rôle des ressources cognitives dans leur déploiement

The current study investigated the age-related differences in control strategies deployment, and examined the relations of control strategies with indicators of well-being and cognitive efficiency. Eighty-five participants aged from 18 to 93 years old completed measures of control strategies and anxiety, and were administered several cognitive tests designed to assess processing speed, reasoning and episodic memory. Results showed that (1) middle-aged individuals use more control strategies based on emotional regulation and goal disengagement than younger and older individuals, (2) individuals who deploy more control strategies focused on emotions report lower levels of anxiety, and (3) cognitive resources moderate the relation between age and control strategies deployment. That is, although increased age is associated with lower deployment of control strategies, the current project showed that age effects in control strategies were weaker for people with higher levels of cognitive resources than for people with lower levels of cognitive resources.     

Treatment Effectiveness of PMTO for Children's Behavior Problems in Iceland: Child Outcomes in a Nationwide Randomized Controlled Trial

Well‐documented treatment methods must be tested following their implementation in community service agencies and across different cultures to ensure continuing effectiveness. This study was a randomized controlled trial (RCT) of Parent Management Training—the Oregon model (PMTO), conducted within a nationwide implementation in Iceland. Families of 102 clinically referred children with behavior problems were recruited from five municipalities throughout Iceland. Child age ranged from 5 to 12; 73% were boys. Families were randomly assigned to either PMTO or services usually offered in the communities (SAU). Child adjustment was measured with a latent construct based on parent, child, and teacher reports of externalizing and internalizing problems and social skills. Prepost intent‐to‐treat analyses showed that PMTO treatment led to greater reductions in child adjustment problems relative to the comparison group, obtaining a modest to medium effect size based on the construct score. Only one indicator (parent‐rated Social Skills) showed significant change independently and information on amount and kind of treatment in the SAU was limited. Overall, findings indicate that PMTO is an effective method to treat children's behavior problems in a Northern European culture and supply evidence for the method's successful implementation in community settings in Iceland. This is one of few nationwide implementation studies of PMTO outside the United States and the first RCT in Iceland to test a treatment model for children's behavior problems.     

Imitation: definitions, evidence, and mechanisms

Imitation can be defined as the copying of behavior. To a biologist, interest in imitation is focused on its adaptive value for the survival of the organism, but to a psychologist, the mechanisms responsible for imitation are the most interesting. For psychologists, the most important cases of imitation are those that involve demonstrated behavior that the imitator cannot see when it performs the behavior (e.g., scratching one's head). Such examples of imitation are sometimes referred to as opaque imitation because they are difficult to account for without positing cognitive mechanisms, such as perspective taking, that most animals have not been acknowledged to have. The present review first identifies various forms of social influence and social learning that do not qualify as opaque imitation, including species-typical mechanisms (e.g., mimicry and contagion), motivational mechanisms (e.g., social facilitation, incentive motivation, transfer of fear), attentional mechanisms (e.g., local enhancement, stimulus enhancement), imprinting, following, observational conditioning, and learning how the environment works (affordance learning). It then presents evidence for different forms of opaque imitation in animals, and identifies characteristics of human imitation that have been proposed to distinguish it from animal imitation. Finally, it examines the role played in opaque imitation by demonstrator reinforcement and observer motivation. Although accounts of imitation have been proposed that vary in their level of analysis from neural to cognitive, at present no theory of imitation appears to be adequate to account for the varied results that have been found.
