Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman
Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman
Department of Psychology Faculty Scholarship and Creative Works
The dependence of episodic memories on interhemispheric processing was tested. In Experiment 1, positive familial sinistrality (FS+; e.g., the presence of left-handed relatives) was associated with superior episodic memory and inferior implicit memory in comparison with negative familial sinistrality (i.e., FS-). This reflected a greater degree of interhemispheric interaction in FS+ participants, which was hypothesized as facilitating episodic memory. In Experiment 2, the authors directly manipulated inter- versus intrahemispheric processing using tests of episodic (recognition) and semantic (lexical decision) memory in which letter strings were presented twice within trial blocks. Semantic memory was superior when the 2nd presentation went to …
Temporal Response Of The Human Visual System To Suprathreshold Luminance And Opponent Colour Contrast Gratings, Melanie Bucking
Temporal Response Of The Human Visual System To Suprathreshold Luminance And Opponent Colour Contrast Gratings, Melanie Bucking
Theses and Dissertations (Comprehensive)
The goal of the present study was to characterize the temporal processing of both suprathreshold luminance and opponent-colour defined contrast in the human visual system. We used a detection task in five experiments; following a 900 Hz, 2-cycle tone, observers were presented with a sinusoidal grating stimulus. The interval separating the waming tone and the presentation of the grating was manipulated to determine the influences of attentional dwell time in a cross-modal task. This theory states that the first of two successive events will interfere with the processing of the second event. In all four luminance experiments the gratings were …
The Effect Of Delta-9-Tetrahydrocannabinol (Thc) On Lithium-Induced Sickness Reactions In Both Rats (Rattus Norvegicus) And The House Musk Shrew (Suncus Murinus), Stephen W.P. Kemp
The Effect Of Delta-9-Tetrahydrocannabinol (Thc) On Lithium-Induced Sickness Reactions In Both Rats (Rattus Norvegicus) And The House Musk Shrew (Suncus Murinus), Stephen W.P. Kemp
Theses and Dissertations (Comprehensive)
The following experiments examined the ability of delta-9-tetrahydrocannabinol (THC) to attenuate lithium induced sickness in both the nonemetic rat (Rattus norvegicus) and the emetic house musk shrew (Suncus murinus). The ability of THC to attenuate the expression of previously established lithium induced conditioned sickness behavior in Suncus was also examined. Although unconditioned sickness behavior was displayed by both rats and shrews, THC did not attenuate this behavior in either species. However, THC did attenuate conditioned retching in the Suncus murinus. These results are the first to show the attenuation of conditioned sickness in Suncus by THC. They also experimentally verify …
Sensitization To Indirect And Direct Dopamine Agonists: Behavioural Differences In Wheel Running, Vanhthong Vilaysinh
Sensitization To Indirect And Direct Dopamine Agonists: Behavioural Differences In Wheel Running, Vanhthong Vilaysinh
Theses and Dissertations (Comprehensive)
Five experiments examined the effects of repeated exposure to stimulants, largely apomorphine (APO), on wheel running in male Sprague-Dawley rats. In these experiments, minor changes in procedure resulted in profound differences in the effects of APO on wheel running. Experiment 1 I compared changes in wheel running after repeated injections of 3.0 mg/kg amphetamine (AMP), 5.0 mg/kg of APO or vehicle (VEH). AMP resulted in a suppression in wheel running which become more pronounced over trials, while running in APO animals remained similar to the VEH group. Testing provided support for a conditioned suppression of wheel running rats previously treated …
The Effect Of Delta9-Tetrahydrocannabinol (Thc) On The Establishment And The Expression Of Place Conditioning (Rattus Norvegicus), Robert Ernest Sorge
The Effect Of Delta9-Tetrahydrocannabinol (Thc) On The Establishment And The Expression Of Place Conditioning (Rattus Norvegicus), Robert Ernest Sorge
Theses and Dissertations (Comprehensive)
The place conditioning paradigm has been used to assess the antinausea potential of drugs in non-emetic animal species. The present experiments were designed to determine the potential of A9-tetrahydrocannabinol (THC) to alleviate both conditioned and unconditioned sickness in rats (Rattus norvegiens). The results in the present study suggest that when the place aversion is strong (Experiment 1), THC may interfere with the establishment; however when the aversion is weak (Experiments 2 and 3), THC may interfere with the expression. Also, when administered during acquisition of a strong amphetamine-induced place preference, THC also seems to interfere with the establishment of the …
