Purpose: The purpose of this study is to identify relationships among the word-finding behaviors ratio using discourse production task, subjective memory, and objective memory in healthy elderly adults.Methods: Ninety-five adults participated study. Participants were used picture description tasks. To evaluate deficit elderly, Subjective Memory Complaints Questionnaire (SMCQ) was used, deficit,...

Patients with early stage Alzheimer's disease (AD) show deficits in person knowledge and spatial associative memory. The current investigation examined the ability of impairment in these domains to differentiate AD from other overlapping conditions. In experiment 1, 14 AD patients, 21 vascular dementia (VaD) patients, 11 frontal variant frontotemporal dementia (fvFTD) patients and 41 controls w...

We investigated the semantic blocking effect in picture naming and word-picture matching for two nonfluent aphasic patients who show evidence of a deficit in inhibiting verbal representations (M.L. and B.Q), one fluent aphasic patient (K.V.), and neurologically intact control participants. In two picture-naming tasks (Experiments 1A and 1B), M.L. and B.Q, relative to controls, showed a greatly ...

This paper proposes the hierarchical naming scheme, which is a way of naming and addressing suitable for large-scale distributed systems. FIrst, assumptions of the systems are provided, and features required for naming in the systems are discussed. Then, the methods for giving location-independent IDs and addresses representing objects' location are proposed. Our scheme constructs global IDs an...

BACKGROUND Children with specific language impairment (SLI) have problems not only with language performance but also with sustained attention, which is the ability to maintain alertness over an extended period of time. Although there is consensus that this ability is impaired with respect to processing stimuli in the auditory perceptual modality, conflicting evidence exists concerning the visu...

Multiple accounts have been proposed to explain category-specific recognition impairments. Some suggest that category-specific deficits may be caused by a deficit in recurrent processing between the levels of a hierarchically organized visual object recognition system. Here, we tested predictions of interactive processing theories on the emergence of category-selective naming deficits in neurol...

Older adults' relatively better memory for positive over negative material (positivity effect) has been widely observed in Western samples. This study examined whether a relative preference for positive over negative material is also observed in older Koreans. Younger and older Korean participants viewed images from the International Affective Picture System (IAPS), were tested for recall and r...

The combination of investigating child and family characteristics sheds light on the constellation of risk factors that can ultimately lead to dyslexia. This family-risk study examines plausible preschool risk factors and their specificity. Participants (N = 196, 42 % girls) included familial risk (FR) children with and without dyslexia in Grade 3 and controls. First, we found impairments in ph...

The overall goals of this study were to test single versus multiple cognitive deficit models of dyslexia (reading disability) at the level of individual cases and to determine the clinical utility of these models for prediction and diagnosis of dyslexia. To accomplish these goals, we tested five cognitive models of dyslexia--two single-deficit models, two multiple-deficit models, and one hybrid...
