introduction: this  research was done to comparison  directionality of drawing fixed shapes in preschoolers and primary school according to role of  handedness.   materials and methods:  in this research causality – comparison, 160 children (80 girls and 80 boys) with mean age of 7/96 in preschool and primary school selected with randomly cluster sampling. the tests were used , handedness quest...

We tested two hypotheses to determine whether dorsal cochlear nucleus (DCN) neurons are specialized to derive directionality from spectral notches: DCN neurons exhibit greater spectral-dependent directionality than ventral cochlear nucleus (VCN) neurons, and spectral-dependent directionality depends on response minima (nulls) produced by coincidence of best frequency (BF) and spectral-notch cen...

Previous research (Oberauer & Wilhelm, 2000) has shown an inherent directionality between the two terms linked in premises of typical deductive reasoning tasks. With three experiments we investigated the effect of inherent directionality on the time to integrate two premises and for the derivation of a conclusion. We varied figure (i.e., order of terms in the premises) and direction of inferenc...
