Purpose: In this study, the authors used cued shadowing to examine children's phonological word-form representations by studying the effects of onset and rhyme primes on lexical access. Method: Twenty-five preschoolers with specific language impairment (SLI; hereafter known as the SLI group), 24 age- and gender-matched children (AM group), and 20…

Children with Developmental Coordination Disorder (DCD) show deficits in the covert orienting of visuospatial attention, suggesting an underlying issue in attentional disengagement and/or inhibitory control. However, an important theoretical issue that remains unclear is whether the pattern of deficits varies with DCD severity. Fifty-one children…

Despite their lack of vision, congenitally blind subjects are able to build and manipulate cognitive maps for spatial navigation. It is assumed that they thereby rely more heavily on echolocation, proprioceptive signals and environmental cues such as ambient temperature and audition to compensate for their lack of vision. Little is known, however,…

The provision of online counselling and emotional support is a subject of intense debate among service providers. The subject is explored here by triangulating data from a statistical analysis of data from a children's helpline, interviews with practitioners and a focus group. Despite practitioners' concerns relating to misinterpretation,…

Purpose: This preliminary investigation assessed the attentional processes of preschool-age children who do (CWS) and do not stutter (CWNS) during Traditional cueing and Affect cueing tasks. Method: Participants consisted of 12 3- to 5-year-old CWS and the same number of CWNS (all boys). Both talker groups participated in two tasks of shifting and…

Behavioral evidence concerning memory in forms of high-functioning autism (HFA) and in moderately low-functioning autism (M-LFA) is reviewed and compared. Findings on M-LFA are sparse. However, it is provisionally concluded that memory profiles in HFA and M-LFA (relative to ability-matched controls) are similar but that declarative memory…

In four experiments, task-switching processes were investigated with variants of the alternating runs paradigm and the explicit cueing paradigm. The classical diffusion model for binary decisions (Ratcliff, 1978) was used to dissociate different components of task-switching costs. Findings can be reconciled with the view that task-switching…

When observers search for a target object, they incidentally learn the identities and locations of "background" objects in the same display. This learning can facilitate search performance, eliciting faster reaction times for repeated displays. Despite these findings, visual search has been successfully modeled using architectures that maintain no…

Four experiments contrasted the predictions of a general encoding-retrieval match hypothesis with those of a view claiming that the distinctiveness of the cue-target relationship is the causal factor in retrieval. In Experiments 1, 2, and 4 participants learned the relationships between 4 targets and trios of cues; in Experiment 3 there were 3…

There is a general consensus among second-language (L2) researchers today that lexical inferencing (LIF) is among the most common techniques that L2 learners use to generate meaning for unknown words they encounter in context. Indeed, claims about the salience and pervasiveness of LIF for L2 learners rely heavily upon data obtained via concurrent…

Although previous research has reported impairments in implicit learning in individuals with ASD, research using one implicit learning paradigm, the contextual cueing task (Chun and Jiang in Cognitive Psychol 36:28-71, 1998), shows evidence of intact ability to integrate spatial contextual information. Using an adaptation of this paradigm, we…

The study presented here sought to explore the role of auditory cues in the spatial knowledge of blind individuals by examining the relation between the perceived auditory cues and the landscape of a given area and by investigating how blind individuals use auditory cues to create cognitive maps. The findings reveal that several auditory cues…

Although exposure-based treatments appear to be efficacious for the treatment of anxiety-related disorders, many individuals experience a renewal of the original fear response at follow-up. In an effort to prevent fear renewal, researchers have begun to use exposure of the conditioned stimulus in different contexts during extinction. Although…

The social-pragmatic theory of language acquisition proposes that children only become efficient at learning the meanings of words once they acquire the ability to understand the intentions of other agents, in particular the intention to communicate (Akhtar & Tomasello, 2000). In this paper we present a neural network model of word learning which…

Multiple cue probability learning (MCPL) involves learning to predict a criterion based on a set of novel cues when feedback is provided in response to each judgment made. But to what extent does MCPL require controlled attention and explicit hypothesis testing? The results of two experiments show that this depends on cue polarity. Learning about…
