Behavioral markers of chronic low-level lead exposure in young mice were examined in the present study. Three groups of C57BL/6J mice (N = 35) were exposed from birth to PND 28 to one of three lead acetate levels: 0 ppm (control), 30 ppm (low-dose), or 330 ppm (high-dose). On PND 28, and immediately prior to sacrifice, mice were tested on the novel odor recognition task [(NODR) (memory task)], on the open field task [(OF) (exploratory behavior, habituation, and anxiety behavior task)], and on the nose poke task [(NP) (exploratory behavior task)]. Blood lead levels were analyzed with inductively coupled plasma …

Eyewitness Memory In Adults, Carlos Manuel Vargas
Open Access Theses & Dissertations
This study encompasses the areas of eyewitness misidentifications and eyewitness suggestibility by developing a Video Suggestibility and Eyewitness Identification Scale for adults. Two hundred one college students were recruited to test this novel psychometric scale following procedures loosely based on the Gudjonsson Suggestibility Scales. The two main subscales proposed are labeled True, which measures non-leading questions answered correctly, and Yield, which measures questions endorsed based on misinformation; two lineup identification subscales were also analyzed for exploration. Reliability estimates showed acceptable internal consistency of True and Yield subscales after negative feedback was provided; while reliability in Target Present Lineups increased and …
