Rule-Based Category Learning In Children: The Role Of Inhibitory Control, Rahel R. Rabi Jul 2012

Rule-Based Category Learning In Children: The Role Of Inhibitory Control, Rahel R. Rabi

Electronic Thesis and Dissertation Repository

The present study examined category learning in relation to inhibitory control and working memory in children and adults. Results revealed that categorization performance improved with age. Young children struggled with rule learning, many older children were successful at rule learning, and most adults had no difficulty with the task. Model-based analyses suggested that performance differences were due to young children’s inability to inhibit the salient, but irrelevant rule. Interestingly, when the analyses focused only on older children and adults who used the task appropriate strategy, the age-related rule-based deficit disappeared. Also, results revealed that successful performance on the categorization task …


The Effects Of Neonatal Immune System Activation With Lipopolysaccharide On Adolescent And Adult Anxiety Behaviours In Male And Female Rats, Alina Zaltzman Jul 2012

The Effects Of Neonatal Immune System Activation With Lipopolysaccharide On Adolescent And Adult Anxiety Behaviours In Male And Female Rats, Alina Zaltzman

Electronic Thesis and Dissertation Repository

The present study examined the effects of neonatal (postnatal days 3 and 5) acute immune system activation with lipopolysaccharide (LPS) on adolescent and adult anxiety behaviours. The major findings suggest that neonatal LPS does not have general long-lasting effects on adolescent anxiety and locomotor behaviours. Rather, early endotoxin treatment has highly specific effects on certain anxiety behaviours that vary depending on the development period. Moreover, neonatal LPS does not seem to influence adult voluntary and non-voluntary locomotor activity or anhedonia, independent of, or in response to, an adult immune challenge. Finally, sex differences were observed in various responses in adulthood, …
