Change Detection In Rhesus Monkeys And Humans, Deepna T. Devkar, Deepna T. Devkar Dec 2014

Change Detection In Rhesus Monkeys And Humans, Deepna T. Devkar, Deepna T. Devkar

Dissertations & Theses (Open Access)

Visual working memory (VWM) is the temporary retention of visual information and a key component of cognitive processing. The classical paradigm for studying VWM and its encoding limitations has been change detection. Early work focused on how many items could be stored in VWM, leading to the popular theory that humans could remember no more than 4±1 items. More recently, proposals have suggested that VWM is a noisy, continuous resource distributed across virtually all items in the visual field, resulting in diminished memory quality rather than limited quantity. This debate about the nature of VWM has predominantly been studied with …


Effect Of Anchoring On Perceived Amniocentesis Related Miscarriage Risk Within A Latina Population, Laura E. Panos May 2011

Effect Of Anchoring On Perceived Amniocentesis Related Miscarriage Risk Within A Latina Population, Laura E. Panos

Dissertations & Theses (Open Access)

Most recognized pregnancies are completed without difficulty, yet there is always a 3-5% background risk to have a child with a birth defect. Amniocentesis, the most common type of prenatal diagnostic test, is used to detect chromosomal abnormalities, such as Down syndrome. Amniocentesis is associated with a risk of complications that can lead to a miscarriage, which is typically quoted to be between 1 in 300 and 1 in 500. Amniocentesis uptake rates are typically lowest within the Latina community, and although the factors related to this have been studied before, no specific conclusions have been reached.

The general population …


Knowledge And Perception Of The Role Of Targeted Ultrasound In Detecting Down Syndrome Among A High Risk Population, Ashley M. Henriksen May 2011

Knowledge And Perception Of The Role Of Targeted Ultrasound In Detecting Down Syndrome Among A High Risk Population, Ashley M. Henriksen

Dissertations & Theses (Open Access)

The purpose of this study was to determine the perception and knowledge of targeted ultrasound in women who screen positive for Down syndrome in the first or second trimester, and to assess the perceived detection rate of Down syndrome by targeted ultrasound in this population. While several studies have reported patient perceptions’ of routine ultrasound, no study has specifically examined knowledge regarding the targeted ultrasound and its role in detecting Down syndrome. A targeted ultrasound is a special ultrasound during the second trimester offered to women who may be at a higher-than-average risk of having a baby with some type …
