Investigated the development of syntactic awareness in Cantonese-speaking children. Fifty-six subjects from four age groups were asked to judge the grammaticality of 40 sentences and to correct the grammatically-deviant sentences. There was a significant age effect on subject's performance in both judgment and revision tasks. (Author/VWL)

Examines project teams and performance-centered design and electronic performance support systems. Topics include performance improvement; technology development; skills; subject expertise; organizational communication; the role-skill paradox; task analysis; and interpersonal communication. (LRW)

A multiple probe across subjects design was used to evaluate the effectiveness of embedded instruction with three students with developmental disabilities who were enrolled in general education classrooms. Two general education teachers delivered embedded instruction to students during regularly schedule instructional activities. The skills taught…

Background: Semantic and inferencing abilities have not been fully examined in children with communication difficulties. Aims: To investigate the inferential and semantic abilities of children with communication difficulties using newly designed tasks. Methods & Procedures: Children with different types of communication disorder were compared with…

Eight- to 12-month-olds might make A-not-B errors, knowing the object is in B but searching at A because of ancillary (attention, inhibitory, or motor memory) deficits, or they might genuinely believe the object is in A (conceptual deficit). This study examined how diligently infants searched for a hidden object they never found. An object was…

In this paper we discuss an experiment that was carried out with a prototype, designed in conformity with the concept of parallelism and the Parallel Instruction theory (the PI theory). We designed this prototype with five different interfaces, and ran an empirical study in which 18 participants completed an abstract task. The five basic designs…

In this article, the author explains the key differences among three kinds of instructionally relevant tests that can have a huge impact on what goes on in classrooms: "instructionally insensitive tests," "instructionally sensitive tests," and "instructionally informative tests." If educators understand the advantages and limitations of these…

Purpose: Vietnamese children's performance on language-based processing tasks of fast-mapping (FM) word-learning and dynamic assessment (DA) word- and rule-learning tasks were investigated. Method: Twenty-one first- and second-generation Vietnamese preschool children participated in this study. All children were enrolled in 2 Head Start programs…

The study investigated theory of mind and central coherence abilities in adults with high-functioning autism (HFA) or Asperger syndrome (AS) using naturalistic tasks. Twenty adults with HFA/AS correctly answered significantly fewer theory of mind questions than 20 controls on a forced-choice response task. On a narrative task, there were no…

This study inspected the processes of verifying the current discourse constituent against the referents that it passively cues during reading. It seemed plausible that, after understanding "The customer ate pancakes," the processes of fully understanding "The waiter implied that the customer ate eggs" might resemble those of intentionally…

Although valenced information about novel animals changes the implicit and explicit fear beliefs of children (Field & Lawson, 2003), how it might lead to anxiety is unknown. One possibility, based on cognitive models of anxiety, is that fear information creates attentional biases similar to those seen in anxiety disorders. Children between 7 and 9…

Four-month-old infants were habituated with an upright or an upside-down face. Eye-movement recordings showed that the upright and upside-down faces were not explored the same way. Infants spent more time exploring internal features, mainly in the region of the nose and mouth, when the face was upright. They also alternated as frequently between…

Thirty-two subjects completed 2 stimulus equivalence tasks using a matching-to-sample paradigm. One task involved direct reinforcement of conditional discriminations designed to produce derived relations between self-referring stimuli (e.g., me, myself, I) and positive evaluation words (e.g., whole, desirable, perfect). The other task was designed…

Performance in 2 versions of a computer-animated task was compared. Participants either indicated the time of arrival of a target that rolled off a horizontal surface and fell--hidden from view--onto a landing point (production task) or judged flight time on a rating scale (judgment task). As predicted, performance was significantly better in the…

Attentional allocation in feature-search mode (W. F. Bacon & H. E. Egeth, 1994) is thought to be solely determined by top-down factors, with no role for stimulus-driven salience. The authors reassessed this conclusion using variants of the spatial cuing and rapid serial visual presentation paradigms developed by C. L. Folk and colleagues (C. L.…
