micrornas (mirnas) are short, endogenous non-coding rnas that function as guide molecules to regulate transcription of their target messenger rnas. several methods including low-density qpcr arrays are being increasingly used to profile the expression of these molecules in a variety of different biological conditions. reliable analysis of expression profiles demands removal of technical variati...

Event-related potentials (ERPs) were recorded during a picture naming task of simple and complex words in children with typical speech and with childhood apraxia of speech (CAS). Results reveal reduced amplitude prior to speaking complex (multisyllabic) words relative to simple (monosyllabic) words for the CAS group over the right hemisphere during a time window thought to reflect phonological ...

The present research examined whether a communicator's verbal, implicit message regarding a target is used as a cue for inferring that communicator's social identity. Previous research has found linguistic intergroup bias (LIB) in individuals' speech: They use abstract language to describe in-group targets' desirable behaviors and concrete language to describe their undesirable behaviors (favor...

In 1957, Skinner, in his "Verbal Behavior", proposed an explanation on how a language is learned. In 1959, Chomsky strongly argued the non-learnability of language, establishing in the field of developmental psycholinguistics the substitution of the term "learning" for that of "acquisition". Currently, the constructivist models describe language acquisition as a process of ontogenetic, gradual,...

Introduction: Non-verbal communication skills, also called signlanguage or silent language, include all behaviors performed in thepresence of others or perceived either consciously or unconsciously.The main aim of this review article was to determine the effectof the teachers’ non-verbal communication on success in teachingusing the findings of the studies conducted on the relationshipbetween q...

A new gamma camera based on hydrogenated amorphous silicon (a-Si:H) pixel arrays to be used in nuclear medicine is introduced. Various performance characteristics of a-Si:H imagers are reviewed and compared with those of currently used equipment. An important component in the a-Si:H imager is the scintillator screen. A new approach for fabrication of high resolution CsI(Tl) scintillator layers,...

Embedded validity measures can screen for possible noncredible performance, but there is a paucity of literature with youth who have neurological disorders. The purpose of this study is to examine the California Verbal Learning Test, Children's Version (CVLT-C) recognition discriminability (RD) score as an embedded validity marker in a sample of youth with neurological diagnoses. Youth between ...

Web-based software was used to deliver and record the effects of programmed instruction that progressively added formal prompts until attempts were successful, programmed instruction with one attempt, and prose tutorials. Error-contingent progressive prompting took significantly longer than programmed instruction and prose. Both forms of programmed instruction substantially increased the approp...
