Screening for autism spectrum disorder in a naturalistic home setting using the systematic observation of red flags (SORF) at 18-24 months.

The purpose of this study was to examine the utility of the Systematic Observation of Red Flags (SORF; Dow et al., 2016) as a level 2 screener for autism spectrum disorder (ASD) in toddlers during a naturalistic video-recorded home observation. Psychometric properties of the SORF were examined in a sample of 228 toddlers-84 with ASD, 82 with developmental delay (DD), and 62 with typical development (TD).

Long and Short Term Cumulative Structural Priming Effects.

We present six experiments that examine cumulative structural priming effects (i.e., structural priming effects that accumulate across many utterances).

Changes in task-extrinsic context do not affect the persistence of long-term cumulative structural priming.

We present two experiments exploring the role of extrinsic memory factors (i.e., factors that are extrinsic to the primary task that is being performed) and intrinsic memory factors (i.

Structural priming as implicit learning: cumulative priming effects and individual differences.

We explored the claim that structural priming is a case of implicit learning within the language production system. The experiment began with a baseline phase, in which we assessed participants' rates of production for double object and prepositional object constructions. Then participants were biased toward the production of either the double object or prepositional object construction.

Long-term cumulative structural priming persists for (at least) one week.

We present an experiment that explores the degree to which cumulative structural priming effects of the sort reported in Kaschak (Memory and Cognition 35:925-937, 2007) persist over the course of a week. In the first session of the experiment, participants completed written sentence stems that were designed to bias them toward producing the double object (Meghan gave Michael a toy) or prepositional object (Meghan gave a toy to Michael) construction. Participants returned for a second session of the experiment a week later.
