The interaction of semantic and orthographic processing during Chinese sonograms recognition: An ERP study

The present study investigated the interaction of semantic and orthographic processing during compound sinogram recognition, using event related potentials (ERPs) and a picture-word matching task. The behavioral results showed that participants generally needed more time to make a response and were more prone to make mistakes, when the paired mismatch sinogram was orthographically similar or semantically related to the picture’s matching name. The N400 results indicated the main effect of semantics and the significant interaction of semantics by orthography. Moreover, only under the semantically related condition (S+), the mean amplitude of N400 was more negative going in orthographically similar condition (O+) than in orthographically dissimilar one (O-), while there was no significant difference under the semantically unrelated condition (S-). Consequently, the sub-lexical orthographic information plays an important role in discriminating the sinograms sharing related semantics

Systematics of Spiny Predatory Katydids (Tettigoniidae: Listroscelidinae) from the Brazilian Atlantic Forest Based on Morphology and Molecular Data

<div><p>Listroscelidinae (Orthoptera: Tettigoniidae) are insectivorous Pantropical katydids whose taxonomy presents a long history of controversy, with several genera incertae sedis. This work focused on species occurring in the Brazilian Atlantic Forest, one of the world's most threatened biomes. We examined material deposited in scientific collections and visited 15 conservation units from Rio de Janeiro to southern Bahia between November 2011 and January 2012, catching 104 specimens from 10 conservation units. Based on morphological and molecular data we redefined Listroscelidini, adding a new tribe, new genus and eight new species to the subfamily. Using morphological analysis, we redescribed and added new geographic records for six species, synonymized two species and built a provisional identification key for the Atlantic Forest Listroscelidinae. Molecular results suggest two new species and a new genus to be described, possibly by the fission of the genus <i>Hamayulus</i>. We also proposed a 500 bp region in the final portion of the COI to be used as a molecular barcode. Our data suggest that the Atlantic Forest Listroscelidinae are seriously endangered, because they occur in highly preserved forest remnants, show high rates of endemism and have a narrow geographic distribution. Based on our results, we suggest future collection efforts must take into account the molecular barcode data to accelerate species recognition.</p></div
