Butler, Brooke M., "The role of death qualification in venirepersons' evaluations of aggravating and mitigating circumstances in capital trials" (2000). Kovera, Gary Moran, Janat Parker, and Ray Taseff, for their wisdom and guidance through this rather grueling (albeit exhilarating) process. I would like to extend special appreciation to my Major Professor, Gary Moran, for his brilliance, his friendship, and his uncanny ability to always make me laugh.I would like to express my sincerest gratitude to my family and friends: my mother, who learned to accept the fact that she raised a daughter who, to her sheer horror, turned out to be a "bleeding-heart liberal;" my late father, who taught me that I could do anything I put my mind to; Karen, analyzed my neuroses; Doug, who listened to my neuroses; Adina, who understood my neuroses; Mark, who sympathized with my neuroses; and Cachi and Marie, who made me laugh at my neuroses.I would like to thank Anders Madsen, the Director of the Jury Pool at the Eleventh Judicial Circuit of the State of Florida, for graciously allowing me to collect my data from bored venirepersons who just wanted to go home. I would also like to extend my appreciation to the secretaries of the Psychology Department, Annette, Carmen, and Luz, for helping me in any way they could (which usually meant looking the other way when their "bruja loquita" exceeded the maximum number of copies she was allowed to make on the copy card).Last but not least, I would like to extend my deepest gratitude to our late Chairperson of the Psychology Department, Scott Fraser, who taught me statistics, unconditional kindness, and that life is much, much too short not to have a good time. in any matter they see fit. Previous research has found that death qualification impacts jurors' receptiveness to aggravating and mitigating circumstances (e.g., Luginbuhl & Middendorf, 1988 In all but a few states that retain capital punishment, the jury has the primary responsibility of pronouncing either a death or life sentence. This obligation is extremely unusual, considering the fact that it is not constitutionally mandated and jury sentencing in non-capital trials is almost extinct (Hans, 1986). A primary difference between capital jurors and jurors in other cases is that death penalty jurors must undergo an extremely controversial process called death qualification.Death qualification is a part of voir dire that is unique to capital trials. During death qualification, prospective jurors are questioned regarding their beliefs about capital punishment. This process serves to eliminate jurors whose attitudes toward the death penalty would render them unable to be fair and impartial in deciding the fate of a defendant. In order to sit on a capital jury, a person must be willing to consider all legal penalties as appropriate forms of punishment. Jurors who "pass" the aforementioned standard are deemed "death-qualified" and are eligible for capital jury service; jurors who "fail" the aforementioned standard are deemed "excludable...
