Learning multiple rules simultaneously: Affixes are more salient than reduplications
Language learners encounter numerous opportunities to learn regularities, but need to decide which of these regularities to learn, because some are not productive in their native language. Here, we present an account of rule learning based on perceptual and memory primitives (Endress, Dehaene-Lambertz, & Mehler, Cognition, 105(3), 577-614, 2007; Endress, Nespor, & Mehler, Trends in Cognitive Sc...
متن کاملCounting descent pairs with prescribed tops and bottoms
Given sets X and Y of positive integers and a permutation σ = σ1σ2 · · ·σn ∈ Sn, an X, Y -descent of σ is a descent pair σi > σi+1 whose “top” σi is in X and whose “bottom” σi+1 is in Y . We give two formulas for the number P n,s of σ ∈ Sn with s X, Y -descents. P X,Y n,s is also shown to be a hit number of a certain Ferrers board. This work generalizes results of Kitaev and Remmel [15] [16] on...
متن کاملq-Counting Descent Pairs with Prescribed Tops and Bottoms
Given sets X and Y of positive integers and a permutation σ = σ1σ2 · · · σn ∈ Sn, an (X,Y )-descent of σ is a descent pair σi > σi+1 whose “top” σi is in X and whose “bottom” σi+1 is in Y . Recently Hall and Remmel [4] proved two formulas for the number P n,s of σ ∈ Sn with s (X,Y )-descents, which generalized Liese’s results in [1]. We define a new statistic statX,Y (σ) on permutations σ and d...
متن کاملInfant discrimination of faces in naturalistic events: actions are more salient than faces.
Despite the fact that faces are typically seen in the context of dynamic events, there is little research on infants' perception of moving faces. L. E. Bahrick, L. J. Gogate, and I. Ruiz (2002) demonstrated that 5-month-old infants discriminate and remember repetitive actions but not the faces of the women performing the actions. The present research tested an attentional salience explanation f...
متن کاملDoes Biosynthetic Silver Nanoparticles Are More Stable With Lower Toxicity than Their Synthetic Counterparts?
Control of size and shape is a challenge in nanoparticle synthesis. Synthetic and biosynthetic (both extracellular and intracellular) methods are used to prepare silver nanoparticle (SNP). In this study, the behavior of three strains of Staphylococcus aureus (S. aureus) was investigated in the presence of silver nitrate intra- and extracellularly. S. aureus strains biosynthesized SNPs intracell...
