The Effects Of Neonatal Immune System Activation With Lipopolysaccharide On Adolescent And Adult Anxiety Behaviours In Male And Female Rats, Alina Zaltzman
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, …
Individual Differences In Temperament And Cognitive Biases In Middle Childhood: Vulnerability To Internalizing Psychopathology, Patricia L. Jordan
Individual Differences In Temperament And Cognitive Biases In Middle Childhood: Vulnerability To Internalizing Psychopathology, Patricia L. Jordan
Electronic Thesis and Dissertation Repository
A multi-trait multi-method study was conducted exploring associations between individual differences in child temperament and cognitive vulnerability for depression and anxiety. Two-hundred and five 7-year-old children and their parents participated. Low positive emotionality and high negative emotionality predicted a depressogenic attributional style as well as attentional biases for positive and sad stimuli. Individual differences in child fearfulness were also associated with attentional biases to threat-related information. Associations between child cognitive vulnerability and parental history of depression and anxiety were also explored, as well as associations between child internalizing symptoms and (1) child temperament and (2) cognitive vulnerability. Paternal, but not …
