Book Description
Understanding spoken communication in noisy environments is a task a majority of the world's population takes part in each day. This process is called speech perception. An individual's auditory, visual, and cognitive ability are important during speech perception in non-ideal listening conditions, and while the contributions of perceptual and cognitive abilities have been documented for younger (i.e., 18-30 years old) and older adults (i.e., 60+years old), studies have almost exclusively failed to include non-geriatric adults between 31 and 59 years old. The purpose of the current study was to identify the auditory, visual, and/or cognitive abilities, which could individually or collectively predict an individual's improvement in speech recognition performance, derived from seeing a speaker's face in a non-geriatric adult (i.e., 20-59 years old) sample. The results indicate no age-related differences in the ability to integrate audiovisual speech information. Rather, these data reveal that differences in working memory capacity (WMC) and perceptual ability modulate the noise level at which their maximum integration occurred. Non-geriatric adults with smaller working memory capacities experience maximum integration in quieter noise levels, demonstrating a reliance on perceptual abilities; however, as the environment becomes noisier their inferior WMC limits their ability to compensate and they have difficulty identifying the target speech. Alternatively, those participants with larger WMCs experience maximum integration in louder noise levels. They have a certain immunity to the effects of noise, allowing them to identify speech under poorer (i.e., louder) listening conditions. Additionally, maximum integration is experienced in more advantageous (i.e., quieter) listening conditions with increasing age, indicating the optimal noise levels for speech recognition differ with age.

Book Description
This newly revised and updated Fourth Edition continues to focus on speech therapy, addressing concerns that aid in the rehabilitation and recovery of aphasia patients. Topics include: assessment of language and communication, principles of language intervention, restorative approaches to language intervention, cognitive neuropsychological approach implications, functional intervention, and treatment for each syndrome. Other approaches and therapy for associated neuropathologies of speech and language related functions are also discussed. For more information, visit http: //connection.LWW.com/go/chapey.

Book Description
The purpose of this study was to investigate the effects of semantic associational strength (SAS) upon adult aphasics' auditory comprehension abilities. Twenty-eight adult aphasics (25 males and 3 females) and 12 normal control subjects were presented three experimental tasks, each containing 45 items. Experimental task 1 contained single word picture sets of high SAS, moderate SAS, and low SAS words. Experimental task 2 contained two word picture sets of high, moderate, and low SAS words, and experimental task 3 contained three word picture sets of high, moderate, and low SAS words. Subjects heard one, two, and three word verbal sequences for experimental tasks 1, 2, and 3, respectively, and pointed to the appropriate picture sequence. Level of SAS was determined on the basis of the two most frequently occurring word associations of 50 normal individuals to 195 words selected from the most frequently occurring 3,000 English words. The findings in this study revealed that aphasics had substantially more difficulty auditorily selecting picture sequences of high SAS words than sequences of moderate and low SAS words, and more difficulty auditorily selecting picture sequences of moderate SAS words than sequences of low SAS words. Results further indicated that, irrespective of degree of SAS between words, aphasics' retentional ability was adversely influenced by an increase in verbal sequence length. The presence of a significant interaction between the SAS and length factors negated the support for an interaction hypothesis that degree of SAS would differentially affect aphasics' comprehension as message length increased. Aphasics' performance on the experimental task was highly related to their overall communicative ability as assessed by the Porch Index of Communicative Ability.
