Cognitive tutors have been shown to increase student learning in long-term classroom studies but would become even more effective if they provided collaborative support and metacognitive tutoring. Reconceptualizing an established tutoring system as a research platform to test different collaborative and metacognitive interventions would lead to gains in learning research. In this paper, we defi...

This study examined secondary outcomes of a randomized clinical trial that evaluated an individual cognitive-behavioral (ICBT), family-based cognitive-behavioral (FCBT), and family-based education, support and attention (FESA) treatment for anxious youth. Participants (161) were between 7 and 14 years (M=10.27) of age and had a principal diagnosis of separation anxiety disorder, social phobia, ...

BACKGROUND Cognitive traits derived from neuropsychological test data are considered to be potential endophenotypes of schizophrenia. Previously, these traits have been found to form a valid basis for clustering samples of schizophrenia patients into homogeneous subgroups. We set out to identify such clusters, but apart from previous studies, we included both schizophrenia patients and family m...

This paper presents an approach to modeling social transgressions in agent based systems. The approach is intended to be abstract enough that it may be used with many different theories of transgression, apology, forgiveness, etc. We discuss an implementation of this approach in PMFserv, an agent based socio-cognitive modeling framework.

Intelligent Tutoring Systems (ITSs) that adapt to an individual student’s needs have been shown to be extremely effective, showing significant improvement in achievement over non-adaptive instruction (Murray 1999). The most successful of these systems require the construction of complex cognitive models that are applicable only to a specific tutorial in a specific field, requiring the time of e...

In this paper, we explore the hypothesis that episodic memory is a critical component for cognitive architectures that support general intelligence. Episodic memory overlaps with case-based reasoning (CBR) and can be seen as a taskindependent, architectural approach to CBR. We define the design space for episodic memory systems and the criteria any implementation must meet to be useful in a cog...

abstract background and purpose: distress is an important issue with significant effects on nurses and patients in the nursing profession. this study aimed to investigate the effects of mindfulness-based cognitive therapy (mbct) on the distress tolerance of nurses with job burnout. methods: this quasi-experimental study was conducted with a pretest-posttest design and a control group. study pop...

objectives: this study aimed at investigating the effectiveness of mindfulness based cognitive therapy (mbct) in management of pain and functional limits of chronic pain patients. methods & materials: in this semi-experimental study, 30 volunteer female patients suffering from chronic pain attending a clinical assessment for treatment of chronic pain were recruited using the convenience samplin...

Wireless multimedia applications require significant bandwidth, some of which will be provided by third-generation (3G) services. Even with substantial investment in 3G infrastructure, the radio spectrum allocated to 3G will be limited. Cognitive radio offers a mechanism for the flexible pooling of radio spectrum using a new class of protocols called formal radio etiquettes. This approach could...
