Learning a keying sequence you never executed: Evidence for independent associative and motor chunk learning

A substantial amount of research has addressed how people learn and control movement sequences. Recent results suggested that practice with discrete key pressing sequences results in two types of sequence learning: associative learning and motor chunk development (Verwey & Abrahamse, 2012). In the present study, we addressed whether in keying sequences of limited length associative learning develops also when the use of the chunking mode is prevented by introducing during practice random deviants. In line with the notion of two different learning mechanisms, the present results indicate that associative sequence learning develops when motor chunks cannot be developed during practice. This confirms the notion that motor chunks do not rely on these associations. In addition, experience with a particular execution mode during the practice phase seems to benefit subsequent use of that mode with unfamiliar and random sequences. Also, participants with substantial video-gaming experience were faster in executing discrete keying sequences in the chunking mode. These last two results may point to the development of a general ability to produce movement sequences in the chunking mode.     

Multilevel modelling: Beyond the basic applications

Over the last 30 years statistical algorithms have been developed to analyse datasets that have a hierarchical/multilevel structure. Particularly within developmental and educational psychology these techniques have become common where the sample has an obvious hierarchical structure, like pupils nested within a classroom. We describe two areas beyond the basic applications of multilevel modelling that are important to psychology: modelling the covariance structure in longitudinal designs and using generalized linear multilevel modelling as an alternative to methods from signal detection theory (SDT). Detailed code for all analyses is described using packages for the freeware R.     

The Pathoplastic Relationship Between Interpersonal Problems and Fear of Failure

ABSTRACT This study advances the understanding of fear of failure (FF), a dispositional avoidance-oriented achievement motive, by employing interpersonal classification techniques to groups of individuals who fear failure in order to examine the pathoplastic relations between FF and interpersonal problems. Shame-based FF is thought to be related to the self-regulation strategies of appeasement and aggression, and these strategies are hypothesized to be associated with the interpersonal problems of Nonassertiveness and Vindictiveness, respectively. Using 2 independent samples ( n s=60 and 38) reporting high FF, interpersonal profiles were examined for the groups in their entirety and for cluster solutions within the larger samples. Results demonstrated that individuals high in FF exhibited 1 of 2 prototypical interpersonal profiles associated with Domineering/Vindictive or Nonassertive/Exploitable problems that correspond with the hypothesized aggression and appeasement regulation strategies. Consistent with the concept of pathoplasticity, these differences were not better accounted for by demographic, affective, motivational, personality, or attachment style characteristics of the samples.     

Improving access to psychological therapy: Initial evaluation of two UK demonstration sites

Recently the UK Government announced an unprecedented, large-scale initiative for Improving Access to Psychological Therapies (IAPT) for depression and anxiety disorders. Prior to this development, the Department of Health established two pilot projects that aimed to collect valuable information to inform the national roll-out. Doncaster and Newham received additional funds to rapidly increase the availability of CBT-related interventions and to deploy them in new clinical services, operating on stepped-care principles, when appropriate. This article reports an evaluation of the new services (termed ‘demonstration sites’) during their first thirteen months of operation. A session-by-session outcome monitoring system achieved unusually high levels of pre to post-treatment data completeness. Large numbers of patients were treated, with low-intensity interventions (such as guided self-help) being particularly helpful for achieving high throughput. Clinical outcomes were broadly in line with expectation. 55-56% of patients who had attended at least twice (including the assessment interview) were classified as recovered when they left the services and 5% had improved their employment status. Treatment gains were largely maintained at 10 month follow-up. Opening the services to self-referral appeared to facilitate access for some groups that tend to be underrepresented in general practice referrals. Outcomes were comparable for the different ethnic groups who access the services. Issues for the further development of IAPT are discussed.     

Performance,cardiovascular, and health behavior effects of an inhibitory strength training intervention

Female undergraduates were assigned to one of three groups, two involving regulatory training and one not. Training participants performed for 2 weeks tasks that required strong behavioral restraint (Strong Training) or weak behavioral restraint (Weak Training). Later, they took part in (1) a laboratory session in which they performed tasks with inhibitory components, and (2) a follow-up week in which they provided health behavior reports and used designated dental supplies. No Training participants took part only in the session and follow-up week. As expected, laboratory performance was improved for Strong- relative to No Training participants, with performance for Weak Training participants falling in between. Also as expected, Strong Training participants used more floss in the follow-up week than did the No Training participants, with floss for Weak Training participants falling between. Contrary to expectation, Strong Training participants used less toothpaste and reported having brushed less than the No Training participants. In addition, Strong Training participants evinced exaggerated—rather than diminished—cardiovascular responses during the laboratory tasks. The performance and floss use data support the suggestion that inhibitory system strength can be increased through use. The brushing and cardiovascular findings may be interpretable in inhibitory strength terms.     

Rethinking NIMBYism: The role of place attachment and place identity in explaining place‐protective action

The ‘NIMBY’ (Not In My Back Yard) concept is commonly used to explain public opposition to new developments near homes and communities, particularly arising from energy technologies such as wind farms or electricity pylons. Despite its common use, the concept has been extensively critiqued by social scientists as a useful concept for research and practice. Given European policy goals to increase sustainable energy supply by 2020, deepening understanding of local opposition is of both conceptual and practical importance. This paper reviews NIMBY literature and proposes an alternative framework to explain local opposition, drawing upon social and environmental psychological theory on place. Local opposition is conceived as a form of place‐protective action, which arises when new developments disrupt pre‐existing emotional attachments and threaten place‐related identity processes. Adopting a social constructivist perspective and drawing on social representation theory, a framework of place change is proposed encompassing stages of becoming aware, interpreting, evaluating, coping and acting, with each stage conceived at multiple levels of analysis, from intrapersonal to socio‐cultural. Directions for future research and potential implications of the place‐based approach for public engagement by energy policy‐makers and practitioners are discussed.

Why Naturalize Consciousness?

This paper examines the relevance of philosophical work on consciousness to its scientific study. Of particular concern is the debate over whether consciousness can be naturalized, which is typically taken to bear on the prospects for its scientific investigation. It is not at all clear that philosophers of consciousness have properly identified and evaluated the assumptions about scientific activity made by both naturalization and antinaturalization projects. I argue that there is good reason to think that some of the assumptions about physicalism and explanation made by the parties to the debate are open to serious doubt. Thus this paper is an invitation for those inquiring into whether consciousness can be naturalized to more carefully consider the expected payoff of such efforts.     

Verbal intelligence and self-regulatory competencies: Joint predictors of boys’ aggression

Two studies examined the interactive effect of receptive verbal intelligence measured by the Peabody Picture Vocabulary Test and self-regulatory competencies measured in the delay of gratification paradigm on boys’ aggression. Study 1 participants (N = 98) were middle school, low-income boys primarily ethnic minority. Participants for Study 2 (N = 59) were drawn from a treatment camp for boys from low-income neighborhoods with behavioral adjustment problems. In both studies, the interaction between verbal intelligence and self-regulation was significant such that verbal intelligence was associated with lower aggression to a greater extent among boys who had effective self-regulatory skills than among those who had ineffective self-regulatory skills. The implications of these findings for interventions and for a theory of risk factors in aggression are discussed.
