INTRODUCTION Schema-based instruction has been shown to improve diagnostic performance and reduce cognitive load. However, to date, this has only been studied in controlled research settings. More distractions in classrooms may limit generalizability to real-world settings. We evaluated whether schema-based instruction would maintain its effects on cognitive load optimization and performance in...

Episodic memory provides a mechanism for accessing past experiences and has been relatively ignored in computational models of cognition. In this paper, we present a framework for describing the functional stages for computational models of episodic memory: encoding, storage, retrieval and use of the retrieved memories. We present two implementations of a computational model of episodic memory ...

The attribute hierarchy method is a psychometric procedure for classifying examinees’ test item responses into a set of structured attribute patterns associated with different components from a cognitive model of task performance. Results from an AHM analysis yield information on examinees’ cognitive strengths and weaknesses. Hence, the AHM can be used for cognitive diagnostic assessment. The p...

In the area of patient safety, recent attention has focused on diagnostic error. The reduction of diagnostic error is an important goal because of its associated morbidity and potential preventability. A critical subset of diagnostic errors arises through cognitive errors, especially those associated with failures in perception, failed heuristics, and biases; collectively, these have been refer...

Anxiety disorders, especially panic disorder, are the prevalent psychiatric disorders. Given the high prevalence of this disorder (1.5 to 5 percent of the population), significant impact on quality of life and dysfunctional cognitions during panic attacks and cognitive functions, the present study examined the efficacy of cognitive behavioral therapy on improvement of cognitive functions patien...

We investigate a general cognitive model of group behaviors, based on Festinger’s social comparison theory (SCT), a prominent social psychology theory. We describe two possible implementations of SCT process at an architectural level, on the basis of the Soar cognitive architecture. The first, which seems to follow directly from Festinger’s social comparison theory, treats the SCT process as an...

The mind integrates cognitive and perceptual processes that are currently best modeled using many different computational mechanisms. These are difficult to integrate into a single cognitive model and are thus a challenge to developing a unified model of human cognition. This paper presents two computational principles that identify common elements among these mechanisms and uses these principl...

In this work we want to provide a tool for handling information coming from different information sources. In fact the real world we often have to deal with different sources asserting different things and, in order to decide, it is necessary to consider properly each of them trying to put this information together. According to us, a good way to do it is exploiting the concept of trust. In fac...

background: alzheimer's disease is the most common form of dementia which is still difficult to be differentiated from other types of brain disorders. moreover, mild cognitive impairment refers to the presence of cognitive impairments that is not severe enough to meet the criteria of alzheimer's, and its diagnosis in early stages is so critical. there is currently no distinct method available f...
