Substance Use And Subclinical Psychosis Symptoms, Kelsey Hurm
Substance Use And Subclinical Psychosis Symptoms, Kelsey Hurm
Undergraduate Honors Thesis Collection
Research shows that there may be a connection between substance use and the expression of positive psychosis symptoms, most notably delusions and hallucinations (Stefanis, et al. 2004). While substances such as marijuana have received the most attention in the literature (e.g., Grech et aI.., 2005), other substances such as stimulants (e.g., Curran et aI., 2004), tobacco (e.g., Baeza et aI., 2009), and alcohol (e.g., Compton et aI., 2009) have been implicated in exacerbating the risk of psychosis onset. Further, there is mounting evidence that many psychiatric disorders are not discrete categories but rather the tails of dimensions distributed in the …
Effects Of Tylenol And Social Rejection On Memory, Karina Ashley Hamamouche
Effects Of Tylenol And Social Rejection On Memory, Karina Ashley Hamamouche
Undergraduate Honors Thesis Collection
Individuals tend to describe physical pain and social pain with the same terminology (DeWall & Baumeister, 2006; Eisenberger, et aI., 2003; Way, et aI., 2009). There is a neurobiological overlap between the systems that control physical pain and social pain. During both physical pain and social rejection, the same brain areas (insulae in the central cortical fissure) are active. DeWall (2011) found that individuals who received a dose of acetaminophen had less activity in the bilateral anterior insula and bilateral posterior insula during a social rejection stimulation. Because social rejection also increases memory (Pajkos, et aI., 20 I 1), subjects …
Verbal Overshadowing And The Effects Of Earwitness Testimony On The Likelihood Of Correct Identification Of Target Voices, John P. Buckley Iii
Verbal Overshadowing And The Effects Of Earwitness Testimony On The Likelihood Of Correct Identification Of Target Voices, John P. Buckley Iii
Undergraduate Honors Thesis Collection
Verbal overshadowing is the process by which verbalizing memory interferes with the original memory (Schooler & Engstler-Schooler, 1990). While verbal overshadowing is robust with eyewitness events, it is not a definite occurrence. However, can verbal overshadowing affect memories of auditory information? Previous research on earwitness testimony has shown a verbal overshadowing effect in which the ability to accurately identify a witness's voice is impaired after verbally describing the voice participants heard (Perfect, Hunt, & Harris, 2002). I examined how voice lineup identification may be influenced by verbally describing a presented voice, a nonpresented voice, or an unrelated event. Results did …
