Algorithms for relational learning and proposi-tional learning face different statistical challenges. In contrast to propositional learners, rela-tional learners often make statistical inferences about data that exhibit linkage and autocorrela-tion. Recent work has shown that these characteristics of relational data can bias inferences made by relational learners. In this paper, we develop a no...

Educational cognitive tools are interactive, computer-based tools that augment one’s mind to facilitate learning. Examples of these include interactive mathematical software, interactive physics simulations, and interactive biology visualizations. While using these tools a learner’s mind becomes coupled with the tool, forming a cognitive system, such that cognitive processes are distributed acr...

Whether the neural mechanisms that underlie the processing of a second language in highly proficient late bilinguals (L2 late learners) are similar or not to those that underlie the processing of the first language (L1) is still an issue under debate. In this study, a group of late learners of Spanish whose native language is English and a group of Spanish monolinguals were compared while they ...

Feedback processing is important for learning and therefore may affect the consolidation of skills. Considerable research demonstrates electrophysiological differences between correct and incorrect feedback, but how we learn from small versus large errors is usually overlooked. This study investigated electrophysiological differences when processing small or large error feedback during a time e...

Network science has emerged as a powerful tool through which we can study the higherorder architectural properties of the world around us. How human learners exploit this information remains an essential question. Here, we focus on the temporal constraints that govern such a process. Participants viewed a continuous sequence of images generated by three distinct walks on a modular network. Walk...

This study investigates the degree to which native-English speaking learners of Spanish can generate expectations for information likely to occur in upcoming portions of an unfolding linguistic signal. We examine Spanish Clitic Left Dislocation, a long-distance dependency between a topicalized object and an agreeing clitic, whose felicity depends on the discourse. Using a self-paced reading tas...

the present investigation was designed to study the production and comprehension of specific means for information highlighted by advanced iranian learners of english as a foreign language. the study focused on the discourse-pragmatically motivated variations of the basic word order such as inversion, pre-posing, it- and wh-clefts. after taking the nelson test, a homogeneous group was settled. ...

abstract background: the radiographic image accuracy depends on the x-ray film information visibility. good visibility is found by good contrast. radiation exposure parameters (kvp, mas) and film processing conditions have impact on contrast. in dentistry radiography machines, exposure time and processing procedure are set by radiographer. no optimized exposure time and processing conditions ma...
