The present study examined age-related differences in multisensory integration and the role of attention in age-related differences in multisensory integration. The sound-induced flash illusion--the misperception of the number of visual flashes due to the simultaneous presentation of a different number of auditory beeps--was used to examine the strength of(More)
This study assessed whether the comprehension of specific lexical items (a semantic judgment) and reversible passive sentences (a syntactic judgment) would be facilitated by preceding them with either linguistic or extralinguistic context. Twenty aphasic subjects were compared for their ability to comprehend semantic and syntactic components of target(More)
Aphasic subjects' syntactic-based comprehension strategies during reading were investigated. Syntactic distinctions involving tense, word order, and relativization were tested. The results were compared to those previously obtained in the auditory modality (Pierce, 1981; in press). The results indicate that aphasics apply a strategy based on a subject-verb(More)
Aphasic subjects' auditory comprehension of reversible passive sentences is facilitated by preceding predictive and nonpredictive narratives (Hough, Pierce, & Cannito, 1989, Brain and Language, 36, 325-334). The present study found that aphasic subjects also comprehended written reversible passive sentences significantly more accurately when they were(More)
Researchers often conduct visual world studies to investigate how listeners integrate linguistic information with prior context. Such studies are likely to generate anticipatory baseline effects (ABEs), differences in listeners' expectations about what a speaker might mention that exist before a critical speech stimulus is presented. ABEs show that(More)
Although the last decade has witnessed mounting research on the development and evaluation of positive interventions, investigators still know little about the target population of such interventions: happiness seekers. The present research asked three questions about happiness seekers: (1) What are their general characteristics?, (2) What do they(More)
OBJECTIVE In the present study, we sought to investigate whether auditory and tactile cuing could be used to facilitate a complex, real-world air traffic management scenario. BACKGROUND Auditory and tactile cuing provides an effective means of improving both the speed and accuracy of participants' performance in a variety of laboratory-based visual target(More)
Visual perceptual learning (VPL) with younger subjects is associated with changes in functional activation of the early visual cortex. Although overall brain properties decline with age, it is unclear whether these declines are associated with visual perceptual learning. Here we use diffusion tensor imaging to test whether changes in white matter are(More)
This study assessed aphasic subjects' sensitivity to the given-new structure within simple paragraphs and the extent to which narrative discourse is facilitative of syntactic processing in the absence of semantic constraints. Subjects were divided into four groups along the dimensions of comprehension level and fluency. Stimulus items consisted of(More)
The influence of prior linguistic predictive and nonpredictive context on the comprehension of reversible passive sentences was investigated in 16 adults with aphasia. Eight subjects were classified as fluent and 8 as nonfluent. Subjects were presented with the sentences in isolation and preceded by nonpredictive and predictive contextual paragraphs. The(More)
