Effect Of Menstrual Cycle Related Estrogen Fluctuations On Working Memory, Mia Segal
Effect Of Menstrual Cycle Related Estrogen Fluctuations On Working Memory, Mia Segal
Electronic Thesis and Dissertation Repository
Working memory (WM) is a dynamic brain system which allows for the on-line moment-to-moment maintenance, processing and monitoring of information involved in human cognition. Behavioural and neuroimaging studies have shown that the prefrontal cortex (PFC) plays an essential role in WM. Data suggest the PFC may be susceptible to modulation by estrogen. Behavioural studies examining whether PFC-dependent WM tasks exhibit estrogen sensitivity in postmenopausal women have shown a benefit of estrogen. The present study used hormone changes associated with the menstrual cycle to examine whether estrogen has a beneficial effect on WM function in reproductively aged women. Thirty-six women completed …
Rule-Based Category Learning In Children: The Role Of Inhibitory Control, Rahel R. Rabi
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 …

Context Is Everything: Facilitating Fit When New Products Are Ambiguous, Theodore J. Noseworthy
Electronic Thesis and Dissertation Repository
Researchers have long believed that consumers adjust their functional expectations in accordance with a product’s physical appearance. Recently this belief has come under fire. Product categories are converging rapidly. Take modern cell phones; the physical appearance of the iPhone is only tangentially related to the breadth of its functionality. Examples like this have sparked a wealth of interest in exploring how consumers generate inferences for products with functions that span multiple categories. One important finding is that consumers tend to generate functional inferences based mainly on the knowledge of a single category. This suggests that new hybrid products are not …
