Feedback As A Source Of Criterion Noise In Recognition Memory, Bryan Franks
Feedback As A Source Of Criterion Noise In Recognition Memory, Bryan Franks
LSU Master's Theses
In two experiments, I investigated whether providing accuracy feedback on recognition memory tests affects discriminability of encoded targets from lures. The primary hypothesis was that feedback is a source of criterion noise which leads to lower discriminability. Additionally, it was predicted that separate sources of criterion noise might have additive effects. In both experiments, the presence of feedback was manipulated within-subjects. In Experiment 1, participants completed two recognition tests in which they made either “old/new” decisions or responded using an 8-point confidence scale. Feedback lowered discriminability for both response type conditions, although a slightly larger deleterious effect was observed in …
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 …
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 …
