Fetal responsiveness to auditory and tactile stimulation
… fetal behavioural responses to auditory and tactile stimulation. Responses were examined for the second- and third-trimester fetuses (second-trimester ≤ 27 gestational weeks (wGA), third- trimester >27 wGA), in both experiments, respectively.<br/><br/>Experiment 1 of this thesis examined …

Modification of a dichotomous tactile stimulation technique for left and right hemispheric specialization in normal and dyslexic readers
… and dyslexic male readers using a dichotomous tactile stimulation technique. The study was a modification of Witelson's (1974; 1976) studies using non-verbal (shapes) and verbal (letters) stimuli. An additional verbal (objects) task, in which subjects recognized and verbally reported the …

Interactions of Early-life Temperature Exposure, Offspring Genotype and Maternal Care on Later-life Maternal Care Provisioning in Female Rats
… exposure and levels of supplemental licking-like tactile stimulation. The second project investigated the main effects of observed early-life inter-individual maternal licking received and interactions with naturally occurring genetic variants in dopamine-related genes. I hypothesized that …

One step ahead: Investigating the influence of prior knowledge on the perception of others’ actions
… momentum paradigm, as well as a cross-modal visuotactile paradigm were employed to test the hypothesis that people’s perceptual processes while observing the actions of others would be affected by such top-down cues about the actor’s intentions. We found, first, that people overestimate other …

Investigating social cognition and personal space through tactile event-related potentials in virtual reality
Heightened neural responses to tactile stimuli over the somatosensory cortex in peripersonal space (PPS) have been found in previous research, with a similar enhancement occurring during social cognition. This heightened somatosensory response is indicative of the brain’s sensitivity to respond to …

Investigation of the Clinical Utility of the Spatio-Spectral Dynamics of Sensorimotor ECoG in Response to Different Somatosensory Stimulation Modalities in Human Subjects
… function. Usually, following the electrical stimulation of the peripheral nerves, visual assessment of the phase reversal of the somatosensory evoked potentials (SSEPs) is employed to delineate the central sulcus (CS). However, proper assessment of the phase reversal in the SSEP waveform is …

Four- and 7-month-old infants' sensitivities to contingency during face-to-face social interactions
… condition were reinforced through standardized tactile stimulation for gazing at an experimenter's neutral face. Yoked infants in the noncontingent condition received the same tactile stimulation regardless of their behaviours. Infants in the contingent condition learned the contingency; their …

Predictive Measures of Fetal Distress in Calves During Delivery
… with longer tongues are less responsive to tactile stimulation. While not conclusive, our data strongly suggest that tongue parameters can be useful as predictive measures of stress, but when all three stress indicators are present in the calf (long tongue, reduced reflex, and dark color) it …

Perception of patterned vibratory stimulation: An evaluation of the tactile vision substitution system
… to provide visual aids for the blind. The tactile vision substitution system (T.V.S.S.) is an example of one such visual aid. The system presents patterned tactile stimulation to the skin of the observer provided by the output of a closed-circuit television system. Research conducted with …

Dynamic Tactile Information is Sufficient for Precise Curvature Discrimination
<p>Our tactile perceptual experiences occur when we interact, actively and passively, with environmental objects and surfaces. Previous research has demonstrated that active manual exploration enhances the tactile perception of object shape. Nevertheless, the factors that contribute to this …

Auditory Stimulation of Comatose Patient : An Exploratory Case Study
… of intermittent, repetitive, long-term auditory stimulation.</p> <p>A patient who appeared to be unconscious thirty-three days, who had no evidence of extensive cortical damage and who had no evidence of hearing difficulties participated. The experimental stimulation was applied by earphones and …

The Analysis of a Substrate Preference of PEROMYSCUS (Rodentia: Cricetidae)
… rocks is elicited by both the shading and the tactile stimulation they provide rather than by any preference for their visual form.</p> <p>Simultaneously, several biological and methodological variables were monitored. The biological variables were: species, sex experience (whether previously …

What Next? Unpacking Anticipatory EEG Oscillations in Auditory, Tactile and Visual Modalities: Relations with Behavior and Executive Function in Children and Adults
… correlates of anticipatory attention to visual, tactile and auditory stimuli with inter- and intra-individual variation in executive function (EF) abilities. Consistent with prior findings (Weiss, Meltzoff, & Marshall, 2018), the sensorimotor mu rhythm in the alpha range of the EEG signal was …

fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications
… using computer controlled and reproducible tactile stimulation. It was found that both the optimal spatial resolution and preferred level of smoothing were intimately coupled to the experiment’s contrast-to-noise. These results were utilised for monitoring sensory activation of S1 in three …

The development of the preterm infant's responsiveness to auditory and tactile social stimuli prior to 40 weeks' postconceptional age
… that preterm infants receive inappropriate tactile and auditory stimulation because of early birth, few studies have explored the development of responsiveness to tactile and auditory stimulation prior to 40 weeks' postconceptional age. The present research traced longitudinally the …

Incidence of hypoxaemia with intravenous fentanyl and midazolam sedation in adult patients undergoing oral surgery procedures
… not given routinely, unless indicated. Verbal or tactile stimulation was performed to encourage respiratory effort when SpO2 ≤94%. Monitoring continued for forty minutes from the time of sedation end point. Data were exported from the ‘BeneVision N12 Mindray’ monitor to Microsoft Excel. …

Relations between sensory-related factors and stress in autistic and non-autistic adults
… Parenting often comes with increased sensory stimulation, such as noise or tactile stimulation. Therefore, responsivity to sensory stimuli could be a risk factor for parenting stress. Autistic parents and Highly Sensitive Persons (HSP) may be particularly at risk of elevated parenting stress, …
