From task characteristics to learning: A systematic review

Wielenga‐Meijer, E. G. A., Taris, T. W., Kompier, M. A. J. & Wigboldus, D. H. J. (2010). From task characteristics to learning: A systematic review. Scandinavian Journal of Psychology, 51, 363–375. Although many theoretical approaches propose that job characteristics affect employee learning, the question is why and how job characteristics influence learning. The present study reviews the evidence on the relationships among learning antecedents (i.e., job characteristics: demands, variety, autonomy and feedback), learning processes (including motivational, meta‐cognitive, cognitive and behavioral processes) and learning consequences. Building on an integrative heuristic model, we quantitatively reviewed 85 studies published between 1969 and 2005. Our analyses revealed strong evidence for a positive relation between job demands and autonomy on the one hand and motivational and meta‐cognitive learning processes on the other. Furthermore, these learning processes were positively related to learning consequences.     

Virtual reality technology in neuropsychological testing: A systematic review

Neuropsychological testing aims to measure individuals' cognitive abilities (e.g. memory, attention), analysing their performance on specific behavioural tasks. Most neuropsychological tests are administered in the so-called ‘paper-and-pencil’ modality or via computerised protocols. The adequacy of these procedures has been recently questioned, with more specific concerns about their ecological validity, i.e. the relation between test scores observed in the laboratory setting and the actual everyday cognitive functioning. In developing more ecological tasks, researchers started to implement virtual reality (VR) technology as an administration technique focused on exposing individuals to simulated but realistic stimuli and environments, maintaining at the same time a controlled laboratory setting and collecting advanced measures of cognitive functioning. This systematic review aims to present how VR procedures for neuropsychological testing have been implemented in the last years. We initially explain the rationale for supporting VR as an advanced assessment tool, but we also discuss the challenges and risks that can limit the widespread implementation of this technology. Then, we systematised the large body of studies adopting VR for neuropsychological testing, describing the VR tools' distribution amongst different cognitive functions through a PRISMA-guided systematic review. The systematic review highlighted that only very few instruments are ready for clinical use, reporting psychometric proprieties (e.g. validity) and providing normative data. Most of the tools still need to be standardised on large cohorts of participants, having published only limited data on small samples up to now. Finally, we discussed the possible future directions of the VR neuropsychological test development linked to technological advances.     

An all‐or‐nothing thinking turns into darkness: Relations between dichotomous thinking and personality disorders1

Dichotomous thinking is an individual's propensity to think in terms of binary opposition. While this thinking style may be useful for quick decision‐making, some clinical psychologists have indicated that such a style is related to personality disorders. Oshio (2009 ) revealed that the Dichotomous Thinking Inventory (DTI) has significant positive correlations with borderline personality and narcissism. This study examines whether dichotomous thinking is associated with cluster A, B, and C personality disorders. The participants comprised 152 Japanese undergraduates (84 male and 68 female). They completed the DTI and Ten Personality Styles scale (10 PesT; Nakazawa (2006 )), developed from the definitions of personality disorders in the DSM‐IV. Structural equation modeling supported the hierarchical factor structure of personality disorders. The dichotomous thinking effects “cluster” level of disorders more than other levels. The results indicated that thinking dichotomously may lead to wide‐ranging personality disorders.     

Critical thinking: A Socratic model

A concept of critical thinking is developed based on the Socratic method and called accordingly a Socratic model. First the features of critical thinking stressed in this model are stated and illustrated. The Socratic method is presented and interpreted, then taken to yield a model of critical thinking. The process of internalization by which the Socratic model helps us to become critical thinkers is described. Argument analysis is considered as a widely used instructional strategy adaptable for teaching critical thinking on the Socratic model. This Socratic model is advanced as one helpful way of organizing our ideas about critical thinking, helpful in unifying disparate factors and anchoring them in the humanist tradition.     

发散思维的序列位置效应：创新想法动态产生机制的新视角

发散思维的序列位置效应是指随着时间的推移,单位时间内想法生成的数量逐渐降低,但想法的独创性逐渐升高的现象。联想理论和执行控制假说分别侧重对序列位置效应的个体差异和认知加工过程进行解释。神经影像学研究表明,在想法产生的整个阶段序列位置效应依赖于默认网络后部和突显网络的持续增强激活和协同合作;在想法产生的后期阶段,颞-顶区域alpha能量值以及执行控制网络与默认网络的协同模式增强。未来研究需要结合语义和神经动态分析等技术,对序列位置效应的特异性机制、动态加工机制以及影响因素进行深入探究,从而为解构创新思维的动态过程提供新的视角。     

Conspiracist beliefs,intuitive thinking,and schizotypal facets: A further evaluation

This study examined whether thinking style mediated relationships between belief in conspiracy and schizotypy facets. A UK-based sample of 421 respondents completed the Generic Conspiracist Beliefs Scale (GCBS), Oxford-Liverpool Inventory of Feelings and Experiences Short (O-Life), and measures indexing preferential thinking style (proneness to reality testing deficits and Need for Cognition). Path analysis revealed direct and indirect relationships between Conspiracy Beliefs and schizotypy facets. Unusual Experiences had a direct effect on Conspiracy Beliefs and predicted Reality Testing and Need for Cognition. Preferential thinking style mediated the schizotypy-belief in conspiracy relationship. This pattern of results (higher experiential-based processing and lower Need for Cognition) was consistent with intuitive thinking. Introverted Anhedonia and Impulsive Nonconformity predicted Reality Testing and had indirect effects on Conspiracy Beliefs. Finally, Reality Testing predicted Conspiracy Beliefs, whereas Need for Cognition did not. These results confirm that cognitive processes related to thinking style mediate the schizotypy-conspiracist beliefs relationship.     

From reading to thinking: Student lines of thought in a seminar on Christianity and colonialism

This article describes a seminar I taught on Christianity and colonialism. I wanted to introduce students to some content while also allowing them to practice some of the expert skills that we use in religious studies, and more specifically in my own sub‐discipline, the anthropology of religion. In particular, I wanted to make more visible some of our practices of critical reading, and how these can feed into practices of complex thinking. However, given the differences between undergraduate and expert practices, what does “critical reading” and “complex thinking” look like in the undergraduate religion classroom? The article presents student readings and lines of thought through the semester, and describes how these undergraduates began to approach complex thinking on the topic of Christianity and colonialism.     

A systematic review on perceptual-motor calibration to changes in action capabilities

Perceptual-motor calibration has been described as a mapping between perception and action, which is relevant to distinguish possible from impossible opportunities for action. To avoid movement errors, it is relevant to rapidly calibrate to immediate changes in capabilities and therefore this study sought to explain in what conditions calibration is most efficient. A systematic search of seven databases was conducted to identify literature concerning changes in calibration in response to changes in action capabilities. Twenty-three papers satisfied the inclusion criteria. Data revealed that calibration occurs rapidly if there is a good match between the task that requires calibration and the sources of perceptual-motor information available for exploration (e.g. when exploring maximal braking capabilities by experiencing braking). Calibration can take more time when the perceptual-motor information that is available is less relevant. The current study identified a number of limitations in the field of perceptual-motor research. Most notably, the mean participant age in the included studies was between 18 and 33 years of age, limiting the generalizability of the results to other age groups. Also, due to inconsistent terminology used in the field of perceptual-motor research, we argue that investigating calibration in older cohorts should be a focus of future research because of the possible implications of impaired calibration in an aging society.     

New Insights into the role of the phonological loop in task switching: evidence from three different age groups

ABSTRACT

The phonological loop plays an important role in task switching. Until now, however, it has been unclear whether it is the maintenance of the task sequence or the retrieval of the task goal that requires phonological processing. In the present study, 60 participants (20 children, 20 adolescents, 20 young adults) performed three phonological working-memory tests before they switched between two tasks in a cue-present condition (random task sequence) and in a cue-absent condition (predictable task sequence). Results revealed that better phonological and central-executive working-memory performance predicted lower switch costs. In line with age-differentiation of cognitive abilities switching was less coupled with working memory in adults compared to children and adolescents. Interestingly, however, relations were only demonstrated in the cue-present but not in the cue-absent condition, indicating that it is more the retrieval of the task goal than the maintenance of the task sequence that requires the involvement of phonological processing.     

Interactions of space and language: Insights from the neglect syndrome

The current article speculates about the interrelations between space and language from the perspective of the neglect syndrome. Various conflicting findings are reviewed and the effect of cultural factors is strongly emphasised. Current scientific literature describes relationships between space and language; however, the available data render it difficult to conclude whether it is the primacy of spatial representations or the complex two‐way interaction between linguistic and spatial representations that determines the nature of cognitive processing. It is hoped that studying the neglect syndrome will provide a solution to this problem. Finally, directions for future research are provided that requires bridging the gap between cognitive theorising and neuroscientific approaches.     

Treatment-resistant depression: A systematic review of systematic reviews

The objective of this research study was to assess pharmacological, somatic and/or psychological treatments in adults with a diagnosis of major depressive disorder who have not responded to at least one course of antidepressant medication. We conducted a systematic review to identify systematic scientific reviews and meta-analyses on treatment-resistant depression (TRD) published until February 2012. Of the sixty studies selected, sixteen met the inclusion criteria and were therefore included in the review. We considered eight main themes, including the definition of TRD, long-term results, and different treatment strategies, including so-called somatic therapies. Based on the review, the definition of TRD should be standardized in order to achieve a shared conceptualization of this disorder. This would allow a better understanding among clinicians and researchers in the field, promoting a homogeneous research methodology and thus leading to more reliable and comparable results. This essential conceptual clarification would also have a positive impact on patients with TRD, their families, and social and health systems.     

思维与语言的关系：来自认知神经科学的证据

在有关人类心智的研究中,思维与语言的关系始终是一个复杂而重要的课题。借助于新的技术手段和研究思路,当代认知神经科学从新的角度探讨了这个古老而神秘的课题。其研究的基本逻辑是：如果某种特定的思维过程（比如简单的算术运算或者三段论推理）在本质上是“语言的”,那么,在进行这种思维活动时,大脑中负责语言信息处理的区域就会参与;反之,如果某种思维过程在本质上是“空间的”,则大脑中负责空间信息处理的区域就会参与其中。结合来自直观的脑功能图谱证据与其它的跨领域证据（如来自行为实验和脑损伤研究的证据）,能够帮助我们更加深入地认识和理解思维与语言的关系问题。     

Cognitive effects of MBSR/MBCT: A systematic review of neuropsychological outcomes

Mindfulness is theorised to improve attention regulation and other cognitive processes. This systematic review examines whether 8-week standardised and manualised mindfulness training programs such as Mindfulness Based Cognitive Therapy (MBCT) and Mindfulness Based Stress Reduction (MBSR) enhances attention, memory and executive function abilities measured by objective neuropsychological tests. Seven databases were searched resulting in 18 studies meeting inclusion criteria for review. Overall studies did not support attention or executive function improvements. We found preliminary evidence for improvements in working memory and autobiographical memory as well as cognitive flexibility and meta-awareness. Short-term mindfulness meditation training did not enhance theorised attentional pathways. Results call into question the theoretical underpinnings of mindfulness, further highlighting the need for a comprehensive theoretical framework.     

Reply to William R. Ferrell's paper "Calibration of sensory and cognitive judgments: A single model for both"

William R. Ferrell's paper is a reply to our article "Calibration of sensory and cognitive judgments: Two different accounts", 1993, 34, 135–148 in this journal. Ferrell's critique centres around three issues: (1) The model of sensory discrimination proposed by Björkman et al. (1993) and discussed in Winman and Juslin (1993) is not new, (2) this model does not predict underconfidence, (3) there is no need for separate models of calibration of sensory and cognitive judgments. Below we respond to each of the three issues raised by Ferrell.     

Competing stimulus assessments: A systematic review

The current review summarizes the literature on competing stimulus assessments (CSAs). CSAs are pretreatment assessments designed to systematically identify stimuli that reduce problem behavior (PB), ostensibly through reinforcer competition or substitution. We report on the participant characteristics, outcomes, and predictive validity of published CSAs that included (a) no-stimulus control trial(s), (b) test trials during which each stimulus was available singly and noncontingently, and (c) measurement of PB and stimulus engagement or contact. Results showed that CSAs have broad utility across a variety of topographies and functions of PB. In the majority of CSA applications for which extended analyses, or validations, were performed, stimuli shown to reduce PB during the CSA produced similar reductions during extended analysis. This was the case regardless of topography or function of PB, or whether the stimuli were assumed to be “matched” to the stimulation thought to be produced by PB. Implications for future research are discussed.     

Atypical shape bias and categorization in autism: Evidence from children and computational simulations

The shape bias, a preference for mapping new word labels onto the shape rather than the color or texture of referents, has been postulated as a word‐learning mechanism. Previous research has shown deficits in the shape bias in children with autism even though they acquire sizeable lexicons. While previous explanations have suggested the atypical use of color for label extension in individuals with autism, we hypothesize an atypical mapping of novel labels to novel objects, regardless of the physical properties of the objects. In Experiment 1, we demonstrate this phenomenon in some individuals with autism, but the novelty of objects only partially explains their lack of shape bias. In a second experiment, we present a computational model that provides a developmental account of the shape bias in typically developing children and in those with autism. This model is based on theories of neurological dysfunctions in autism, and it integrates theoretical and empirical findings in the literature of categorization, word learning, and the shape bias. The model replicates the pattern of results of our first experiment and shows how individuals with autism are more likely to categorize experimental objects together on the basis of their novelty. It also provides insights into possible mechanisms by which children with autism learn new words, and why their word referents may be idiosyncratic. Our model highlights a developmental approach to autism that emphasizes deficient representations of categories underlying an impaired shape bias.     

Oxford cognitive screen: A critical review and independent psychometric evaluation

The Oxford cognitive screen (OCS) is a stroke-specific cognitive screening assessment. Although the test developers have provided psychometric information for the assessment, the OCS has received minimal external scrutiny, with which to triangulate the underpinning psychometrics. The purpose of this study is to provide a critical review and independent validation of the OCS. This study analysed data from an anonymised clinical database, which consisted of 316 patients who were assessed using the OCS on an Acute Stroke Unit. The rates of impairment on tests of memory and receptive communication were lower than expectation, suggesting that these subtests may be relatively insensitive. Patients with aphasia were more likely to be unable to categorised as impaired on non-language tests, suggesting that they remain sensitive to language processing or non-dominant hand usage. Some of the subtests of the OCS achieve high retest reliability, which makes them good candidates for measuring cognitive change over time. Although the OCS has many advantages, it is also important to adequately consider its limitations, that is insensitivity to memory problems, the potential confounding impact of non-dominant hand usage, and the potential that some tests may sample overall cognitive ability instead of domain-specific functioning.     

Constructive Thought Strategies and Job Satisfaction: A Preliminary Examination

In order to examine the potential of constructive thought strategies for enhancing employee job satisfaction, an existing dispositional model of job satisfaction was expanded and tested. Structural equation modeling techniques indicated significant relationships among constructive thought strategies, dysfunctional thought processes, subjective well-being, and job satisfaction. In addition, two competing models were examined to test for the full or partial mediation of the effects of constructive thought strategies on job satisfaction. The implications of these findings for constructive thought strategy training interventions are discussed, along with directions for future research efforts.     

Preschoolers’ use of feedback for flexible behavior: Insights from a computational model

This study addressed preschoolers’ cognitive flexibility in an inductive task requiring response feedback processing to infer relevant task goals. A total of 63 4- to 6-year-olds were tested on a perceptual matching task in which they needed to switch attention among three colors. A computational model was designed to track down how responses to positive and negative feedback changed as children progressed through the task. The results showed that children’s differential response to positive and negative feedback developed with age. In addition, age differences in feedback responding increased as the task unfolded. These findings are interpreted as reflecting an increase in flexibility with age in terms of growing efficiency in feedback processing.
