Semantically Based Lexical Processing Yields Unique Topographic Contributions to the Speech Bereitschaftspotential
… these findings were reports of left lateralized hemispheric asymmetry in the BP topography, shortly before speech onset. Several researchers argued that these shifts were artifacts produced by movements of the articulatory muscles. However, methodological differences between the studies could …

Ear asymmetry : the differential effects of white noise on the perception of voiced and voiceless CV nonsense syllables.
… complexity would enhance the asymmetric hemispheric processing of linguistic stimuli. This hemispheric asymmetry would, in turn, manifest itself in ear asymmetry, more specifically, a right ear preponderance. Under the control condition, one ear received CV syllables and white noise at a …

The face is the thing: faces as a whole are responsible for the lateralization of visual perceptual facial processing
… many of the tasks that have previously shown hemispheric asymmetry, results showed that tasks involving the perception of a face and tasks involving non-face perception loaded on separate factors, indicating they involve independent processes even though both types of tasks are completed by …

Neurosensitivity: Implications for Cognition and Creativity.
… is consistent with cognitive disinhibition and hemispheric asymmetry hypotheses of creativity and models of the creative process suggesting an important role for conscious and unconscious cognition.

On the role of neuronal oscillations in auditory cortical processing
… was aimed at establishing whether there is a hemispheric asymmetry in the way neuronal oscillations are utilized by attention, corresponding to that noted in humans. </p> <p>The results of the first study indicate that in passive conditions, ongoing oscillations reset by stimulus related …

Looking Through the Lens of Individual Differences: Relationships Between Personality, Cognitive Control, Language Processing, and Genes
… results are consistent with previous findings of hemispheric asymmetry in terms of the distribution of dopaminergic and norephinephrine signaling pathways. In Chapter 3, we investigated the extent to which the same processing mechanisms are used to resolve lexical and syntactic conflict. In …

Spatiotemporal Variations in the Radiant Energy Budgets of Mars and Earth
… interseasonal variations with significant hemispheric asymmetry. Near perihelion, global dust storms further perturb these transient, yet periodic energy imbalances. These results are immediately applied to analyze the CO2 budget of Mars’ ice caps. Secondly, Mars’ energy budget is compared …

Training-Induced Changes in Dual -Task fMRI Activation in Young and Old Adults
… were correlated with a significant increase in hemispheric asymmetry and a reduction in age-differences in ventral and dorsal prefrontal cortex. These results indicate that cognitive training programs can reliably alter the functioning of the older and younger adult brain and reduce …

Atypical Lateralization of Language and Face Processing in Autism Spectrum Disorder
… related to reduced functional specialization and hemispheric lateralization of both language and face processing, particularly in posterior lateral temporal cortex. This is an important contribution to the mixed existing literature, and further demonstrates the importance of individual ROI …

A dynamo case study of Mercury, and the early orbital and thermal evolution of the Moon
… lunar nearside. Researchers proposed that this hemispheric asymmetry could be the result of a single diaper ascension of deep, radiogenically heated material, but it is unclear why the diaper occurred in the nearside mantle. In an attempt to explain this observation by heterogeneous tidal …

Simple Models for Complex Tropical Dynamics
… bias is bigger in the Southern Hemisphere. The hemispheric asymmetry in this bias can be traced back to radiation absorbed by the atmosphere, which is associated with dust (for shortwave radiation) and total column water (for longwave radiation). As a whole, this thesis demonstrates the utility …

The Mechanisms and Consequences of Cerebral Lateralization
… Second, what are the consequences of functional asymmetry of cognitive processing in the human brain on our everyday behaviour? Examining 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 …

Neuropsychological effects of anxiety without depression on facial affect perception
… the influence of anxiety without depression on hemispheric processing of Ekman and Friesen's (1976) happy, angry, and neutral emotional faces. Results were counter to hypotheses, where anxious subjects' reaction times to affective valences were slower than nonanxious subjects. Additionally, …

Cerebral Regulation of Cardiovascular Functioning and Fluency among Anxious and Nonanxious Men
This experiment investigated lateralized hemispheric regulation of the autonomic nervous system (ANS) among high anxious and nonanxious university undergraduate men using a novel laboratory paradigm. Specifically, this three phase paradigm entailed the administration of a verbal fluency (left …

Automaticity and Hemispheric Specialization in Emotional Expression Recognition: Examined using a modified Stroop Task
… sad expressions) and the valence hypothesis of hemispheric advantages for emotions (left hemisphere: positive; right hemisphere: negative) were also examined. Four major findings emerged. First, the valence of expressions was processed automatically (robust interference effects). Second, male …

The role of the rostral prefrontal cortex in the context of the aesthetic experience
… reference to existing frameworks. Specifically: hemispheric asymmetry in the processing of emotional stimuli, the Gateway Hypothesis and the Default Mode Network will be explored.Experimental WorkA database of sixty images was created in an online survey (chapter 3) at the beginning of the …
