This paper describes a computational model named Dev E-R (Developmental Engagement-Reflection) that, inspired by Piaget’s theory, simulates the assimilation-accommodation adaptation process. It is implemented with a new extended version of the computational model of creativity known as Engagement-Reflection. That is, this model simulates adaptation as a creative activity. We introduce here the implementation of our model on an agent that is initialized with basic reflex conducts and that through the interaction with a 3D virtual world, it is able to build new behaviors autonomously. The new acquired skills, according to Piaget’s theory, are typically observed in children that have reached the second substage of the sensorimotor period. 相似文献

Including Both Voices: A New Bidirectional Framework for Understanding and Improving Intergroup Relations 下载免费PDF全文
Methods: If successful intergroup harmony is to be achieved between two groups, then both groups' voices must be heard. Despite this, 60 years of social psychological “intergroup” prejudice research has tended to adopt a solely majority‐centric perspective, with the majority group portrayed as the active agent of prejudice, and the minority group as passive targets. Objective: This paper critically reviews relevant literature, highlighting this unidirectional imbalance, and proposes a new, two‐stage bidirectional framework, where we encourage researchers and educators to first understand how minority and majority groups' intergroup attitudes and emotions impact intergroup dynamics, before tailoring and implementing contact and recategorisation strategies to improve intergroup relations, nationally and internationally. Conclusion: We argue that the interactive nature of the intergroup dynamic needs to be better understood, and each group's voice heard, before prejudice can be effectively reduced. Lastly, we describe an Australian study, the Dual Identity and Electronic‐contact (DIEC) programme, that has been conducted and has successfully applied this bidirectional framework. 相似文献

A conspicuous oversight in recent debates about the vexed problem of the value of knowledge has been the value of knowledge-how. This would not be surprising if knowledge-how were, as Gilbert Ryle [1945, 1949] famously thought, fundamentally different from knowledge-that. However, reductive intellectualists [e.g. Stanley and Williamson 2001; Brogaard 2008, 2009, 2011; Stanley 2011a, 2011b] maintain that knowledge-how just is a kind of knowledge-that. Accordingly, reductive intellectualists must predict that the value problems facing propositional knowledge will equally apply to knowledge-how. We show, however, that this is not the case. Accordingly, we highlight a value-driven argument for thinking (contra reductive intellectualism) that knowledge-how and knowledge-that come apart. 相似文献

The Asymptotic Classification Theory of Cognitive Diagnosis (Chiu et al., 2009, Psychometrika, 74, 633–665) determined the conditions that cognitive diagnosis models must satisfy so that the correct assignment of examinees to proficiency classes is guaranteed when non‐parametric classification methods are used. These conditions have only been proven for the Deterministic Input Noisy Output AND gate model. For other cognitive diagnosis models, no theoretical legitimization exists for using non‐parametric classification techniques for assigning examinees to proficiency classes. The specific statistical properties of different cognitive diagnosis models require tailored proofs of the conditions of the Asymptotic Classification Theory of Cognitive Diagnosis for each individual model – a tedious undertaking in light of the numerous models presented in the literature. In this paper a different way is presented to address this task. The unified mathematical framework of general cognitive diagnosis models is used as a theoretical basis for a general proof that under mild regularity conditions any cognitive diagnosis model is covered by the Asymptotic Classification Theory of Cognitive Diagnosis. 相似文献

Clinician-guided Internet-based cognitive behavioural therapy (iCBT) programs are clinically effective at treating specific anxiety disorders. The present study examined the efficacy of a transdiagnostic Internet-based cognitive behavioural treatment (iCBT) program to treat more than one anxiety disorder within the same program (the Anxiety Program). Eighty six individuals meeting diagnostic criteria for generalized anxiety disorder (GAD), panic disorder, and/or social phobia were randomly assigned to a treatment group, or to a waitlist control group. Treatment consisted of CBT based online educational lessons and homework assignments, weekly email or telephone contact from a clinical psychologist, access to a moderated online discussion forum, and automated emails. An intention-to-treat model using the baseline-observation-carried-forward principle was employed for data analyses. Seventy-five percent of treatment group participants completed all 6 lessons within the 8 week program. Post-treatment data was collected from 38/40 treatment group and 38/38 control group participants, and 3-month follow-up data was collected from 32/40 treatment group participants. Relative to controls, treatment group participants reported significantly reduced symptoms of anxiety as measured by the Generalized Anxiety Disorder - 7 Item, Social Phobia Screening Questionnaire, and the Panic Disorder Severity Rating Scale - Self Report Scale, but not on the Penn State Worry Questionnaire, with corresponding between-groups effect sizes (Cohen’s d) at post-treatment of 0.78, 0.43, 0.43, and 0.20, respectively. The clinician spent a total mean time of 46 min per person over the program, participants rated the procedure as moderately acceptable, and gains were sustained at follow-up. Modifications to the Anxiety program, based on post-treatment feedback from treatment group participants, were associated with improved outcomes in the control group. These results indicate that transdiagnostic programs for anxiety disorders may be successfully administered via the Internet. 相似文献

How does mindfulness-based cognitive therapy work? 总被引:1,自引:0,他引:1

Mindfulness-based cognitive therapy (MBCT) is an efficacious psychosocial intervention for recurrent depression (
[Kuyken et?al., 2008],
[Ma and Teasdale, 2004] and [Teasdale et?al., 2000]). To date, no compelling research addresses MBCT’s mechanisms of change. This study determines whether MBCT’s treatment effects are mediated by enhancement of mindfulness and self-compassion across treatment, and/or by alterations in post-treatment cognitive reactivity. The study was embedded in a randomized controlled trial comparing MBCT with maintenance antidepressants (mADM) with 15-month follow-up (Kuyken et al., 2008). Mindfulness and self-compassion were assessed before and after MBCT treatment (or at equivalent time points in the mADM group). Post-treatment reactivity was assessed one month after the MBCT group sessions or at the equivalent time point in the mADM group. One hundred and twenty-three patients with ≥3 prior depressive episodes, and successfully treated with antidepressants, were randomized either to mADM or MBCT. The MBCT arm involved participation in MBCT, a group-based psychosocial intervention that teaches mindfulness skills, and discontinuation of ADM. The mADM arm involved maintenance on a therapeutic ADM dose for the duration of follow-up. Interviewer-administered outcome measures assessed depressive symptoms and relapse/recurrence across 15-month follow-up. Mindfulness and self-compassion were measured using self-report questionnaire. Cognitive reactivity was operationalized as change in depressive thinking during a laboratory mood induction.MBCT’s effects were mediated by enhancement of mindfulness and self-compassion across treatment. MBCT also changed the nature of the relationship between post-treatment cognitive reactivity and outcome. Greater reactivity predicted worse outcome for mADM participants but this relationship was not evident in the MBCT group.MBCT’s treatment effects are mediated by augmented self-compassion and mindfulness, along with a decoupling of the relationship between reactivity of depressive thinking and poor outcome. This decoupling is associated with the cultivation of self-compassion across treatment. 相似文献

Depression is characterized by a large risk of relapse/recurrence. Mindfulness-based cognitive therapy (MBCT) is a recent non-drug psychotherapeutic intervention to prevent future depressive relapse/recurrence in remitted/recovered depressed patients. In this randomized controlled trial, the authors investigated the effects of MBCT on the relapse in depression and the time to first relapse since study participation, as well as on several mood states and the quality of life of the patients. 106 recovered depressed patients with a history of at least 3 depressive episodes continued either with their treatment as usual (TAU) or received MBCT in addition to TAU. The efficacy of MBCT was assessed over a study period of 56 weeks. At the end of the study period relapse/recurrence was significantly reduced and the time until first relapse increased in the MBCT plus TAU condition in comparison with TAU alone. The MBCT plus TAU group also showed a significant reduction in both short and longer-term depressive mood and better mood states and quality of the life. For patients with a history of at least three depressive episodes who are not acutely depressed, MBCT, added to TAU, may play an important role in the domain of relapse prevention in depression. 相似文献
