We investigate the problems of precondition interactions and eeect cumulations, typically caused by the concurrent execution of actions. Our analysis leads to an integration of property oriented and resource oriented approaches to the representation of action and change. We formalize our ideas by introducing an extension AORC of the Action Description Language AC 2]. In order to enable sound an...

The human brain readily perceives fluent movement from static input. Using functional magnetic resonance imaging, we investigated brain mechanisms that mediate fluent apparent biological motion (ABM) perception from sequences of body postures. We presented body and nonbody stimuli varying in objective sequence duration and fluency of apparent movement. Three body postures were ordered to produc...

Sentence production difficulties are a common feature of aphasia. The aim of the current study was to investigate the processes involved in sentence production and to identify whether consistent patterns of difficulties are associated with non-fluent and fluent aphasic speech. An analysis of sentence production was designed which described thematic, phrasal and morphological structure. The sent...

UNLABELLED Relapse following treatment for stuttering is a common problem for many clients. It has often been suggested that one factor contributing to relapse is the client's difficulty in adjusting to a new role as a fluent speaker. In this tutorial article, we first present a personal construct view of relapse, which suggests that this difficulty may be addressed by increasing the meaningful...

Little is known about the processing of non-verbal sounds in the primary progressive aphasias. Here, we investigated the processing of complex non-verbal sounds in detail, in a consecutive series of 20 patients with primary progressive aphasia [12 with progressive non-fluent aphasia; eight with semantic dementia]. We designed a novel experimental neuropsychological battery to probe complex soun...

This paper presents a new approach for classification of dysfluent and fluent speech using Mel-Frequency Cepstral Coefficient (MFCC). The speech is fluent when person's speech flows easily and smoothly. Sounds combine into syllable, syllables mix together into words and words link into sentences with little effort. When someone's speech is dyfluent, it is irregular and does not flow effortlessl...

As a part of my group’s activities on the extension of the fluent calculus (Hölldobler and Schneeberger 1990; Thielscher 1998), I’ve been working to provide an efficient inference engine for the fluent calculus by using the efficiency of binary decision diagrams (BDDs) (Bryant 1986). In the past, BDDs have significantly improved the performance of algorithms and enabled the solution of new clas...

The hereditary character of dyslexia suggests the presence of putative underlying neural anomalies already in preliterate age. Here, we investigated whether early neurophysiological correlates of future reading difficulties-a hallmark of dyslexia-could be identified in the resting-state EEG of preliterate children. The children in this study were recruited at birth and classified on the basis o...

OBJECTIVE To examine the prevalence and predictors of language attainment in children with autism spectrum disorder (ASD) and severe language delay. We hypothesized greater autism symptomatology and lower intelligence among children who do not attain phrase/fluent speech, with nonverbal intelligence and social engagement emerging as the strongest predictors of outcome. METHODS Data used for t...

BACKGROUND this study examines the linguistic features that may influence the occurrence of speech boundaries in fluent and stuttering individuals. AIM the study seeks to examine the influences of tone and position in a word on the occurrence of speech boundaries in stuttering and fluent adolescents and adults. METHOD one hundred and twenty individuals took part in this study, both male and...
