We examined the contribution of executive control to individual differences in response time (RT) for naming objects and actions. Following Miyake et al., executive control was assumed to include updating, shifting, and inhibiting abilities, which were assessed using operation span, task-switching, and stop-signal tasks, respectively. Experiment 1 showed that updating ability was significantly ...

Although language rehabilitation in patients with primary progressive aphasia (PPA) is recommended, rehabilitation studies in this clinical syndrome are scarce. Specifically, in relation to semantic dementia (SD), few studies have shown the possibility of lexical relearning. Objective: To analyze the effectiveness of rehabilitation for lexical reacquisition in SD. Methods: Three SD patients wer...

This paper investigates homophone naming performance in an individual with impaired word retrieval. The aim of the study is to investigate the status of homophone representations using treatment of homophone picture naming in aphasia. The focus of this paper is the representation of heterographic homophones (words which sound the same but are spelled differently, e.g., 'knight' vs. 'night'). Ad...

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...

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...

Background Picture naming is a common tool in aphasia diagnosis and therapy. However, opinions differ as to which type of image (e.g., photographs, drawings) most suitable for tasks whether there difference on correctness latencies based type. Moreover, recent studies have mainly analysed colour photographs black-and-white line drawings leaving out types like graphic representations that apply ...

PURPOSE Current knowledge regarding the topography of essential language cortex is based primarily on stimulation mapping studies of nonlesional epilepsy patients. We sought to determine whether space-occupying temporal lobe lesions are associated with a similar topography of language sites, as this information would be useful in surgical planning. METHODS We retrospectively compared the topo...

Word-retrieval and rapid naming abilities play an important role in language processing and cognitive development. Researchers have demonstrated that early language difficulties may lead to later reading impairments and several decades of research has convincingly demonstrated that rapid automatized naming is a powerful predictor of concurrent and future reading development. As a result, resear...
