Binding Of Independent Contexts In Source Memory, Samantha Nicole Spitler
Binding Of Independent Contexts In Source Memory, Samantha Nicole Spitler
LSU Master's Theses
Within the present study the binding between two independent source dimensions in a multidimensional source memory paradigm was investigated. Specifically, I examined stochastic dependence between the retrieval of each source dimension. Previous work has defined stochastic dependence as the higher probability of correct source retrieval for one dimension contingent on previous correct retrieval of a second source dimension, versus when contingent on incorrect retrieval of the second source dimension. Evidence is mixed as to whether item information within source dimensions must be encoded simultaneously in order to demonstrate eventual stochastic dependence. The present study tested the binding of two cross-modal …
The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira
The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira
LSU Master's Theses
There are different ways of lying and these lies may have different impacts on memory. In this study, participants studied pictures of objects, and later lied and told the truth about these and other objects by describing them or by denying they had seen them. Forty-eight hours later, participants were tested on their source memory. Results revealed that participants had good memory for having falsely described a never-seen object, but poor memory for having falsely denied seeing a studied object. These results suggest that telling certain types of lies may make a person more likely to forget having lied at …
Source Memory And The Picture Superiority Effect, Noelle L. Brown
Source Memory And The Picture Superiority Effect, Noelle L. Brown
LSU Master's Theses
Two experiments were conducted to explore whether a picture superiority effect exists in source memory. To investigate this issue, participants studied a mixed list of pictures and words. Experiment 1 tested people's memory for an organizational source where half the pictures and words were studied on the left or right side of a computer monitor. In Experiment 2 an associative source was tested. During encoding half of the pictures and words were associated with a female voice and the other half with a male voice. At test, participants' memory for the location or voice of the pictures and words was …
Source Memory, Subjective Awareness, And The Word Frequency Mirror Effect, Benjamin A. Martin
Source Memory, Subjective Awareness, And The Word Frequency Mirror Effect, Benjamin A. Martin
LSU Master's Theses
The current study investigated the subjective states of recollection and familiarity in source memory. Participants studied low and high frequency words, presented in one of two sources, and were then asked to make source decisions and subjective judgments of recollection and familiarity at test. Half of participants were asked to identify the source of an item before the subjective awareness judgment (SM-first group), while the other half of participants made a source decision to an item after judging it as recollected or familiar (RF-first group). The test order manipulation affected participants’ patterns of responding. Participants in the RF-first group tended …
How Cue-Dependent Is Memory?: Internal Reinstatement And Cueing Effects In Recognition And Source Memory, Jeffrey Joseph Starns
How Cue-Dependent Is Memory?: Internal Reinstatement And Cueing Effects In Recognition And Source Memory, Jeffrey Joseph Starns
LSU Doctoral Dissertations
This study explored the role of internal context reinstatement in masking the effects of external context cues on recognition and source memory. Participants studied words paired with pictures of male and female faces. Following the study phase, participants completed either a source test in which they decided whether each test word was studied with a male or female face (Experiments 1, 3, and 4) or a recognition test in which they decided whether each test word appeared in the study phase (Experiment 2). On selected trials, a studied face was reinstated at test to serve as a cue for the …
The Effect Of Emotion On Witness Suggestibility, Cristine Carmen Roussel
The Effect Of Emotion On Witness Suggestibility, Cristine Carmen Roussel
LSU Master's Theses
When witnesses are exposed to highly stressful and emotional events, the result is often increased arousal and a change in the pattern of attention. Both of these factors are likely to impact witnesses’ memory for the event. In addition, witnesses are often exposed to post-event information from a variety of sources (e.g., investigators, other witnesses, media reports). The goal of the present study was to explore, in the context of the eyewitness suggestibility paradigm, the impact of emotional arousal and attentional focus on event memory and the incidence of eyewitness suggestibility. A secondary goal of this study was to explore …
The Effects Of Internal And External Context Reinstatement On Source Memory, Jeffrey Joseph Starns
The Effects Of Internal And External Context Reinstatement On Source Memory, Jeffrey Joseph Starns
LSU Master's Theses
Memory for attended aspects of an encoded event (item memory) is facilitated when features of the encoding context are reinstated at test, indicating that item and context features are bound together in memory traces (Smith, 1979). The present study investigated whether reinstated contextual features similarly enhance memory for other contextual details of an event (source memory). Participants studied words that appeared on either the top or bottom of the computer screen in either a large or small font size. Following the study phase, participants completed a recognition/source test in which they had to indicate the location in which they studied …
