THE LATERALIZATION OF THE WORD FREQUENCY EFFECT
… experiments were performed to investigate the lateralization of the word frequency effect and the interaction with word class. Positive results would support proposals of multiple lexicons in lexical retrieval models. The first was a small-n experiment varying visual angle of presentation, …

The Mechanisms and Consequences of Cerebral Lateralization
… the mechanisms that give rise to cerebral lateralization, Experiments 1 and 2 tested the assumption that there is a causal relationship in the degree and direction of lateralization between left- and right-hemisphere dominant tasks. In experiment 1, this relationship between left-hemisphere …

Individual differences in hemispheric lateralization of language processing
… SOA correlated with the dichotic listening lateralization index. Individual differences were unrelated to the lateralized indices.</p> <p>The findings suggest that both dichotic listening and the shorter SOA condition measured automatic or perceptual lateralization whereas the longer SOA …

Vocal Handedness: The Emergence of Lateralization at Fledging
… -namely, locatability. The emergence of vocal lateralization when the bird leaves the nest, regardless of age at which it occurs, is also curious and I posit that if lateralization of function is a way of compartmentalizing the complex world, then perhaps laterality arises when this world is …

Characterizing the perceptual diffusion of auditory lateralization images
When two statistically independent noise sources with different interaural time delays are presented simultaneously over headphones, the separated source images seem to become diffuse and merge over time. Experiments were designed to test the hypothesis that the measure of diffusion perceived would …

Naturalistic Visuomotor Behaviours Reveal Reduced Handedness Lateralization In Autism
… how handedness, a robust marker of cerebral lateralization, is modulated in autistic and non-autistic right-handed adults (n=27 per group) using a naturalistic LEGO® model-building task. Participants recreated five models from blocks placed on a standardized tabletop, enabling detailed …

Lateralization of Emotion, Reaction Time, and Skin Conductance Responsiveness
<p>Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of …

Atypical Lateralization of Language and Face Processing in Autism Spectrum Disorder
… respectively. Furthermore, the degree of lateralization is related to behavioural proficiency in both domains. Converging evidence suggests that the development of lateralization in these separate domains is typically interrelated. Neuroimaging literature demonstrates reduced leftward …

Predicting lateralization performance at high frequencies from auditory-nerve spike timing
Psychophysical sensitivity to interaural time differences (ITD) in the envelope of high- frequency sinusoidally amplitude-modulated (SAM) tones is generally poorer than that to low- frequency pure tones (PT). ITD sensitivity at high frequencies might be improved using "transposed stimuli" (TS), …

Lateralization of Sinusoidally - Amplitude-Modulated Tones: Effects of Spectral Locus and Temporal Variation
… of spectral locus and temporal variation, the lateralization of sinusoidally-amplitude-modulated tones. An acoustic pointing task was employed in which listeners varied the interaural intensitive disparity of a narrow band of noise (the pointer) so that it matched the intracranial position of a …

Lateralization of motor behavior as a measure of cognitive functioning and resting-state electrocortical activity
… and motor measures maps onto hemispheric lateralization and this has important implications for psychopathology (e.g., depression) and cognition. The present study evaluates the relationship between performance on finger-tapping tasks (FTT), alpha power during resting-state …

Developmental Plasticity of Language Representation in Healthy Subjects and Children with Medically Intractable Epilepsy
… of language was determined by comparing lateralization in children with developmental, acquired, and tumour pathologies. Findings from 105 consecutive intracarotid sodium amobarbital procedures were retrospectively analyzed, revealing no lateralization differences between pathology …

The face is the thing: faces as a whole are responsible for the lateralization of visual perceptual facial processing
Previous research has identified multiple tasks that display asymmetries favoring either the left or right hemisphere of the brain. Among these tasks are judgments of facial features, emotion, numerosity, facial resemblance, gender, and line midpoint. Verbal tasks typically display a left …

Lateralized Induction of Cardiovascular Responses: Exploring Asymmetric Autonomic Regulation
… node and the myocardium of the heart. This lateralization has also been observed in afferent as well as efferent projections to nuclei in the brainstem, hypothalamus, and amygdala. Where laterality has not been as clear is in regions of the frontal lobe dedicated to the regulation of …

That's Just Your Point of View: How Visuospatial Biases and Functional Lateralization Influence the Way We Perceive the World
How can individual differences in visuospatial attention and other lateralized functions affect the perception of one’s environment? This research question was examined through the four studies which comprise this dissertation. Studies 1 and 2 examined how visuospatial biases (and other lateralized …

Analysis of early auditory evoked potentials elicited by stimuli with directional information
… of ABRs and BDs rather correspond to the lateralization of the stimuli than to the interaural parameters. Chap. 4 deals with the dipole source analysis of multi-channel ABR data to lateralized clicks. The moment trajectories of a rotating dipole do not correlate with a single interaural …

An fMRI study of object recognition and cerebral laterality
… In the functional localizer experiment, opposite lateralization between words and (to a lesser degree) faces were observed. However, between-category univariate fMRI results were not consistently lateralized to the left hemisphere for words or oppositely lateralized to the right hemisphere for …
