Temporal Shifts In Weapon Focus: Comparing Retrograde And Anterograde Effects, William Blake Erickson May 2012

Temporal Shifts In Weapon Focus: Comparing Retrograde And Anterograde Effects, William Blake Erickson

Graduate Theses and Dissertations

When an eyewitness suffers an impairment of memory for a criminal's face because the criminal used a weapon during the commission of the crime, this impairment is called the weapon focus effect. Literature provides two explanations for how this effect arises: some implicate the narrowing of attentional cues to the weapon during the commission of a crime because arousal of the victim increases, while others claim that the weapon is merely a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm taking place in a …


Responses To Domestic Violence Public Service Ads: Memory, Attitudes, Affect, And Individual Differences, Courtney Elizabeth Welton-Mitchell Jan 2012

Responses To Domestic Violence Public Service Ads: Memory, Attitudes, Affect, And Individual Differences, Courtney Elizabeth Welton-Mitchell

Electronic Theses and Dissertations

Public service ads (PSAs) are an increasingly visible part of efforts to decrease the occurrence and consequences of domestic violence. Like other advertising, domestic violence PSAs are designed to grab attention, influence attitudes, and enhance memory for ad content. Over the years, images in domestic violence PSAs have changed substantially; agencies have started using pictures that generate emotions - either vivid negative images (bruised faces or body parts), or positive images (smiling faces) that contrast with the negative text. It is not clear, however, how different types of ad images influence memory for the message and attitudes about domestic violence, …


The Reversed Testing Effect : Unraveling The Benefits Of Practiced Recall, Katherine Mary Weber Jan 2012

The Reversed Testing Effect : Unraveling The Benefits Of Practiced Recall, Katherine Mary Weber

Legacy Theses & Dissertations (2009 - 2024)

Eyewitness memory for events has been shown to be malleable and susceptible to intrusions of misinformation (Loftus & Palmer, 1974). It has been demonstrated that practicing retrieval of studied material can lead to improved recall, known as the testing effect (Karpicke & Roediger, 2008; Roediger & Karpicke, 2006). However, practiced recall may also lead to the increased incorporation of misinformation into memory, known as the reversed testing effect (Chan, Thomas, & Bulevich, 2009). While Karpicke and Roediger (2008) used Swahili-English word pairs to demonstrate the testing effect, Chan et al. used video materials. In two out of three of the …


Improving Memory Using N-Back Training, Paul Beavon Jan 2012

Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) …
