Laterality Differences in Perception

<p>The subject of this thesis is laterality differences in perception. The term "laterality difference" refers to an asymmetry in report accuracy for stimuli presented about the center of a person's visual field. A discussion of the literature and experimental findings relevant to this topic is first given. This is followed by a detailed analysis of eight experiments which examine the effects of a number of variables on laterality differences. The main conclusion drawn from these experiments is that perceptual laterality differences are a function of acquired. Reading habits, the structural characteristics of the stimuli, and the order in which the stimuli are reported. To a lesser extent, they are also related to certain other factors such as differential eye sensitivity and handedness. An interpretation in terms of a "post-exposure trace-scanning" hypothesis is given to account for the experimental findings.</p>

Study on Palmaris Longus Muscle Tendon Agenesis Among First Year Filipino Medical Students

Introduction: In the recent years palmaris longus muscle tendon (PLMT) has become an extensively and intensively studied muscle all over the world. The main reason for this is the importance of PLMT which was recognized with development of plastic and reconstructive surgery. The possibilities of PLMT use has become bigger and bigger each dayObjectives: The study aimed to evaluate the incidence of agenesis of palmaris longus muscle tendon among first year Filipino medical students at OLFU.Methods: This study was conducted at the Our Lady of Fatima University Medical Centre, Valenzuela City, Philippines. A semi-structured proforma was used to record the relevant data for the study. The Thompson’s test was used for assessing palmaris longus muscle tendon. After taking consent total of 503 first year Filipino medical students were involved.Results: Out of total 503 subjects, 170 (33.80%) were males and 333 (66.20%) were females. Percentage of frequency of agenesis of palmaris longus muscle tendon in both genders was 17.05%. There was no significant gender and laterality difference in the incidence of the agenesis of palmaris longus muscle tendon. That means there are equal chances of palmaris longus muscle tendon agenesis in both gender and the laterality.Conclusions: There was no significant gender and laterality difference in the incidence of the agenesis of PLMT. This means that there are equal chances of PLMT agenesis in both gender and the laterality.Journal of Gandaki Medical College Vol. 10, No. 1, 2017, Page: 17-20

Temporal and Spatial Aftereffects of a Border on an Afterimage and a Possible Laterality Difference

Five subjects were asked to report the brightness and duration of afterimages formed in a region where a border had previously been exposed. The temporal and spatial aftereffects of the border on the formation of the afterimage varied with the duration of the border and these aftereffects were within the area predicted by a photochemical bleaching hypothesis. In addition to these major findings, the experiment yielded some surprising secondary observations. For example, increasing the degree of bleaching or light adaptation made the afterimage brighter if it was on the right side but decreased the brightness if on the left. The difference between afterimages on the right and left sides was discussed in terms of spatial effects of borders and laterality differences.
