This is an article about the methodology of substitution in problem solving mathematics. The operative use depends on two things: equation or situation which variables appear, a change variable, and second, variable effective only if makes expression easier to understand it possible solve problem. Substitution will be successful original has symmetry especial property that explore, proficiency ...

attentional demands and individuals’ cognitive failure are hypothesized to be determinant factors for workload assessment and job analysis, although previous researches have focused merely on one aspect of attentional demands. the objective of this study was to investigate the degree to which various attentional paradigms would be demanding to the participants with different levels of cognitive...

Current models of temporality in language are either inaccurate or too complex to be cognitively plausible. We present a cognitive model of the computation of aspect in French. Our approach emphasizes the importance of minimalism for cognitive plausibility: structures and computation are kept simple and combinatorial explosion is avoided. Though the model and its current implementation remain p...
