This book was released on 2012-12-06 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Language depends on a normally functioning left hemisphere. This central fact of human cerebral dominance was well established by 19th century aphasiologists and has been repeatedly confirmed by subsequent investiga tions. Predominance, however, does not imply exclusivity. As demonstrated by the commissurotomy patients studied by Eran Zaidel and associates, the right hemisphere is also capable of subserving some linguistic functions. The question, then, is not whether the right hemisphere can process language, but how and when it does so. This volume focuses on the right hemisphere's contribution to one important aspect oflanguage, lexical semantics. Although the right hemisphere may well be involved in other linguistic functions, such as prosody, the greatest evidence for right hemisphere language competence has been obtained for the processing of word meanings. In addition, cognitive psychology and psycho linguistics have provided us with well-developed models of the lexicon and lexical access to guide our inquiry. Finally, there are techniques available for studying lateralized lexical processing in the normal as well as in the brain injured hemispheres. For these reasons, a focus on the lexicon is likely to yield the greatest number of insights about right-hemisphere language processing.

Available in PDF, EPUB and Kindle. Book excerpt: The statement, "The Right Hemisphere (RH) processes language"--while not exactly revolutionary--still provokes vigorous debate. It often elicits the argument that anything the RH does with language is not linguistic but "paralinguistic." The resistance to the notion of RH language processing persists despite the fact that even the earliest observers of Left Hemisphere (LH) language specialization posited some role for the RH in language processing, and evidence attesting to various RH language processes has steadily accrued for more than 30 years. In this volume, chapters pertain to a wide, but by no means, exhaustive set of language comprehension processes for which RH contributions have been demonstrated. The sections are organized around these processes, beginning with initial decoding of written or spoken input, proceeding through semantic processing of single words and sentences, up to comprehension of more complex discourse, as well as problem solving. The chapters assembled here should begin to melt this resistance to evidence of RH language processing. This volume's main goal is to compile evidence about RH language function from a scattered literature. The editorial commentaries concluding each section highlight the relevance of these phenomena for psycholinguistic and neuropsychological theory, and discuss similarities and apparent discrepancies in the findings reported in individual chapters. In the final chapter, common themes that emerge from the enterprise of studying RH language and future challenge for the field are reviewed. Although all chapters focus only on "typical" laterality of right handed people, this work provides a representative sample of the current state of the art in RH language research. Important features include: * a wide range of coverage from speech perception and reading through complex discourse comprehension and problem-solving; * research presented from both empirical and theoretical perspectives; and * commentaries and conclusions integrating findings and theories across sub-domains, and speculating on future directions of the field.

Book excerpt: The goal of this study was to test whether semantic priming in response to a word that immediately follows a related sentence or single-word is age-invariant. This was done using the N400 event-related brain potential (ERP). N400 amplitude varies inversely with semantic priming (Kutas, 1980), and this effect is larger for sentence primes than for word primes (Kutas, 1993). ERPs were recorded while 20 older (M = 71.5, SD = 6.4) and 20 young (M = 23.0, SD = 2.3) subjects read word-pairs and highly constrained sentences. Each final word varied on the degree of relatedness to the preceding context, with some being highly related (BC), moderately related (R), or unrelated (U). An Age X Context X Relatedness repeated-measures analysis of variance (ANOVA) was conducted on N400 amplitude at the .05 level of significance. Significant results were further analyzed with Tukey A post-hocs also conducted at the .05 level of significance. In young subjects, N400 amplitude showed the expected N400 effect gradient (U> R> BC) in both the sentence and word-pair contexts. N400 responses in older subjects showed no discrimination between the conditions (U = R = BC) for the word-pairs and limited discrimination (U> BC) for the sentence endings, indicating that older subjects were able to benefit from the constraints of a sentence context. These results provide electrophysiological evidence of age-related changes in semantic priming, and are interpreted in the context of the inhibition-deficit hypothesis (Hasher & Zacks, 1988) whereby older adults fail to inhibit related but irrelevant items in working memory.

This book was released on 2013 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is commonly known that the left hemisphere of the brain is more efficient in the processing of verbal information, compared to the right hemisphere. One proposal suggests that hemispheric asymmetries in verbal processing are due in part to the efficient use of top-down mechanisms by the left hemisphere. Most evidence for this comes from hemispheric semantic priming, though fewer studies have investigated verbal memory in the cerebral hemispheres. The goal of the current investigations is to examine how top-down mechanisms influence hemispheric asymmetries in verbal memory, and determine the specific nature of hypothesized top-down mechanisms. Five experiments were conducted to explore the influence of top-down mechanisms on hemispheric asymmetries in verbal memory. Experiments 1 and 2 used item-method directed forgetting to examine maintenance and inhibition mechanisms. In Experiment 1, participants were cued to remember or forget certain words, and cues were presented simultaneously or after the presentation of target words. In Experiment 2, participants were cued again to remember or forget words, but each word was repeated once or four times. Experiments 3 and 4 examined the influence of cognitive load on hemispheric asymmetries in true and false memory. In Experiment 3, cognitive load was imposed during memory encoding, while in Experiment 4, cognitive load was imposed during memory retrieval. Finally, Experiment 5 investigated the association between controlled processing in hemispheric semantic priming, and top-down mechanisms used for hemispheric verbal memory. Across all experiments, divided visual field presentation was used to probe verbal memory in the cerebral hemispheres. Results from all experiments revealed several important findings. First, top-down mechanisms used by the LH primarily used to facilitate verbal processing, but also operate in a domain general manner in the face of increasing processing demands. Second, evidence indicates that the RH uses top-down mechanisms minimally, and processes verbal information in a more bottom-up manner. These data help clarify the nature of top-down mechanisms used in hemispheric memory and language processing, and build upon current theories that attempt to explain hemispheric asymmetries in language processing.

This book was released on 2017 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current study examined second language learners and employed a masked semantic priming paradigm paired with a lexical decision task in an attempt to better understand the processes of acquiring semantic information from a second language (L2) and organizing into the lexicon of a learner. Results from previous literature reveal discrepant results, with some studies providing support for the Revised Hierarchical Model (RHM) emphasizing direct translation links from the first language (L1) being essential for second language processing, while other studies find that an L1 is not necessarily needed in order to process semantic information, thus, supporting the Distributed Representation Model (DRM). Of additional interest, were both the role of hemispheric processing and the relationship of working memory on second language semantic integration. Results from our study revealed an asymmetrical priming effect from the L2-L1 direction with better accuracy for targets in the left hemisphere providing support for the RHM.

Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2019 in the subject Psychology - Cognition, grade: 1,3, University of Wuppertal, language: English, abstract: In order to retrieve information more efficiently and quickly, our central nervous system makes use of implicit preactivation of associative neural networks. In this study, 78 participants were instructed to identify a sequence of word pairs consisting of either German words, nonwords or pseudowords within a lexical decision task. The procedure was carried out under three different conditions: a) no associations within a word pair, b) connection through general second-level cooccurrences, and c) connection through lemmatized second-level cooccurrences. The analysis of variance revealed highly significant differences in reaction time and error rate between lemmatized second-level cooccurrence compared to general second-level cooccurrences. Both, error rate and reaction time, were lower for lemmatized second-level cooccurrences. Stimuli consisting of words with second-level association had a positive effect on the reaction time and error rate. This could be proven due to a stimulus onset asynchrony of 50ms, avoiding semantical competition that could cause inhibitory effects on the reaction time. Linear regression also revealed that lemmatized second-level cooccurrences had a greater influence on the reaction time up to the target and the error rate compared to general second-level cooccurrences. This information could be used to improve models that explain the process of word recognition by adding the influence of the lemmatized second-level cooccurrence.

This book was released on 2006-05-05 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new edition of the essential resource on using functional neuroimaging techniques to study the neural basis of cognition, revised with the student in mind; thoroughly updated, with new chapters on fMRI physics, skill learning, emotion and social cognition, and other topics. This essential resource on neuroimaging provides an accessible and user-friendly introduction to the field written by leading researchers. The book describes theoretical and methodological developments in the use of functional neuroimaging techniques to study the neural basis of cognition, from early scientific efforts to link brain and behavior to the latest applications of fMRI and PET methods. The core of the book covers fMRI and PET studies in specific domains: attention, skill learning, semantic memory, language, episodic memory, working memory, and executive functions. By introducing a technique within the description of a domain, the book offers a clear explanation of the process while highlighting its biological context. The emphasis on readability makes Handbook of Functional Neuroimaging of Cognition ideal for classroom use in advanced undergraduate and graduate courses in cognitive neuroscience. This second edition has been completely updated to reflect new developments in the field, with existing chapters rewritten and new chapters added to each section. The section on history and methods now includes a chapter on the crucial topic of the physics of functional neuroimaging; the chapters on skill learning and executive functions are new to the domain section; and chapters on childhood development and emotion and social cognition have been added to the section on developmental, social, and clinical applications. The color insert has been increased in size, enhancing the visual display of representative findings. Contributors Todd S. Braver, Jeffrey Browndyke, Roberto Cabeza, B.J.
