Impact Of Adolescent Social Isolation On Adult, Binge-Like Ethanol Consumption And Plasma Corticosterone In High-Alcohol-Preferring Mice, Eva Cullins

The Journal of Purdue Undergraduate Research

Adolescent stress exposure increases the likelihood of alcohol misuse and alcohol use disorder (AUD) in adulthood; however, it is not clear how genetic and environmental factors interact to increase risk. This study examined how adolescent social isolation affects adult binge-like ethanol drinking and levels of the stress hormone corticosterone in male and female mice with a genetic predisposition toward high alcohol preference (HAP). Twenty-eight HAP mice were separated into group-housed (GH) and socially isolated (SI) conditions (n = 13, 13). Binge drinking was assessed using a drinking in the dark (DID) procedure. Blood samples were taken before DID and after …

Sustaining Continuous Improvement In Public Sector Services Through Double Loop Learning, Chris Buckell Msc, Mairi Macintyre Assoc. Prof.

International Conference on Lean Six Sigma

Abstract

Purpose: Public Service Organisations (PSOs) are facing continuing funding challenges and increased pressure to maintain and improve service delivery with fewer resources. One response, with the promise of improving efficiency rather than cutting services, has been to implement Continuous Improvement (CI) but success has been sporadic and unpredictable. The well documented and pervasive CI methodologies in PSOs, including Lean and Six Sigma, have general agreement across practitioners and scholars alike, thus the reasons behind their potted success must lie elsewhere, in the culture or the environment perhaps? This work explores the wider contextual issues of CI implementation with the …

Exploring Animacy As A Mnemonic Dimension, Joshua Edward Vanarsdall

Open Access Dissertations

There is a great deal of evidence across cognitive science that animacy, or more generally, the features that make up what it means to be a living thing, is a foundational dimension of human cognition. In perception, animates both capture attention (Pratt, Radulescu, Guo, & Abrams, 2010) and are relatively immune to change blindness (New, Cosmides, & Tooby, 2007). Developmental work places the animate-inanimate distinction as one of the first categories children learn (Opfer & Gelman, 2011). Work in neuroscience points toward a fundamental role for animacy in semantic memory (Caramazza & Mahon, 2003), and linguists have identified animacy as …

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd

MODVIS Workshop

Lightness matching data from disk-annulus experiments has the form of a parabolic (2^nd-order polynomial) function when matches are plotted against annulus luminance on log-log axes. Rudd (2010) has proposed a computational cortical model to account for this fact and has subsequently (Rudd, 2013, 2014, 2015) extended the model to explain data from other lightness paradigms, including staircase-Gelb and luminance gradient illusions (Galmonte, Soranzo, Rudd, & Agostini, 2015). Here, I re-analyze parametric lightness matching data from disk-annulus experiments by Rudd and Zemach (2007) and Rudd (2010) for the purpose of further testing the model and to try to constrain …

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada

MODVIS Workshop

Signal detection theory has been well accepted in vision science to measure human sensitivity to stimuli in a Psychophysical experiment. The theory is formulated so that the measured sensitivity is independent from a response bias (criterion). The formulation is based on an assumption that number of trials in the experiment is infinite but this assumption cannot be satisfied in practice. The assumption came from two normal distributions used in the formulation. The distributions respectively represent a set of signal trial and that of noise trials in the experiment. In this study, I will show how the violation of the assumption …

The Role Of Attention In Retrieval Practice, Joshua W. Whiffen

Open Access Theses

Dividing attention during encoding is detrimental to learning. In contrast, dividing attention during retrieval appears to have very little effect on recall. However, very few studies have investigated whether dividing attention during initial recall has an impact on subsequent retrieval attempts. ^ Research on retrieval practice has clearly shown that retrieval is an active process that leads to important changes in memory that ultimately enhance long term retention. However, it has yet to be established exactly how retrieval practice derives its benefits. One possibility is that retrieval involves the reinstatement of temporal context, which leads to the updating or encoding …
