Moving along the number line: operational momentum in nonsymbolic arithmetic.
Can human adults perform arithmetic operations with large approximate numbers, and what effect, if any, does an internal spatial-numerical representation of numerical magnitude have on their responses? We conducted a psychophysical study in which subjects viewed several hundred short videos of sets of objects being added or subtracted from one another and judged whether the final numerosity was...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولCalibrating the mental number line.
Human adults are thought to possess two dissociable systems to represent numbers: an approximate quantity system akin to a mental number line, and a verbal system capable of representing numbers exactly. Here, we study the interface between these two systems using an estimation task. Observers were asked to estimate the approximate numerosity of dot arrays. We show that, in the absence of calib...
متن کاملComparing implicit and synaesthetic number-space associations: visuospatial and verbal SNARC effects
In Dehaene’s (1992) theory of the mental number line, number and space are implicitly associated, giving rise to the spatial-numerical association of response codes (SNARC) effect, in which smaller numbers are more readily associated with the left side of space, larger numbers with the right, during a parity judgement task. Others, however, have argued that the SNARC effect is flexible (e.g. Bä...
