Does Unconscious Thought Outperform Conscious Thought On Complex Decisions? A Further Examination, Scott Andrew Withrow, Todd J. Thorsteinson Apr 2009

Does Unconscious Thought Outperform Conscious Thought On Complex Decisions? A Further Examination, Scott Andrew Withrow, Todd J. Thorsteinson

Psychology Faculty Publications

Two experiments examined the benefits of unconscious thought on complex decisions (Dijksterhuis, 2004). Experiment 1 attempted to replicate and extend past research by examining the effect of providing reasons prior to rating the options. Results indicated no significant differences between the conditions. Experiment 2 attempted to replicate the findings of Dijksterhuis, Bos, Nordgren, and van Baaren (2006) and determine if a memory aid could overcome the limitations of conscious thought on complex tasks. Results revealed that a memory aid improved decisions compared to the conscious thought condition. Participants in the unconscious thought condition did not perform significantly better than did …

Animal Metacognition: Problems And Prospects, J. David Smith, Michael J. Beran, Justin J. Couchman, Mariana V.C. Coutinho, Joseph B. Boomer Jan 2009

Animal Metacognition: Problems And Prospects, J. David Smith, Michael J. Beran, Justin J. Couchman, Mariana V.C. Coutinho, Joseph B. Boomer

Language Research Center

Researchers have begun to evaluate whether nonhuman animals share humans’ capacity for metacognitive monitoring and self-regulation. Using perception, memory, numerical, and foraging paradigms, they have tested apes, capuchins, a dolphin, macaques, pigeons, and rats. However, recent theoretical and formal-modeling work has confirmed that some paradigms allow the criticism that low-level associative mechanisms could create the appearance of uncertainty monitoring in animals. This possibility has become a central issue as researchers reflect on existing phenomena and pause to evaluate the area’s current status. The present authors discuss the associative question and offer our evaluation of the field. Associative mechanisms explain poorly …


Development Of Response Evaluation And Decision (Red) And Antisocial Behavior In Childhood And Adolescence, Reid Griffith Fontaine, Chongming Yang, Kenneth A. Dodge, Gregory S. Pettit, John E. Bates Jan 2009

Development Of Response Evaluation And Decision (Red) And Antisocial Behavior In Childhood And Adolescence, Reid Griffith Fontaine, Chongming Yang, Kenneth A. Dodge, Gregory S. Pettit, John E. Bates

Reid G. Fontaine

Using longitudinal data on 585 youths (48% female; 17% African American, 2% other ethnic minority), the authors examined the development of social response evaluation and decision (RED) across childhood (Study 1; kindergarten through Grade 3) and adolescence (Study 2; Grades 8 and 11). Participants completed hypothetical-vignette-based RED assessments, and their antisocial behaviors were measured by multiple raters. Structural equation modeling and linear growth analyses indicated that children differentiate alternative responses by Grade 3, but these RED responses were not consistently related to antisocial behavior. Adolescent analyses provided support for a model of multiple evaluative domains of RED and showed strong …


If The Large Wta-Wtp Gap For Public Goods Is Real (And There Are Good Reasons To Think So) Conventional Welfare Measures Are Simply Incorrect, Philip E. Graves Jan 2009

If The Large Wta-Wtp Gap For Public Goods Is Real (And There Are Good Reasons To Think So) Conventional Welfare Measures Are Simply Incorrect, Philip E. Graves

PHILIP E GRAVES

A robust finding in economics is that decision-makers often exhibit a much smaller dollar willingness to pay (WTP) for an item than the minimum amount that they claim to be willing to accept (WTA) to part with it. The spread between these two numbers is particularly large for public goods, raising serious public policy concerns regarding which number, if either, is appropriate for valuing such goods. A traditional utility maximizing model is presented here that predicts–as both measures are currently calculated–that WTA will exceed WTP, quite plausibly by a substantial amount for public goods. Moreover, it is shown here that …


Does Optimal Distinctiveness Contribute To Group Polarization?, Joo Hwan Lee Jan 2009

Does Optimal Distinctiveness Contribute To Group Polarization?, Joo Hwan Lee

ETD Archive

Group polarization occurs when group members have more extreme views after learning others in the group have similar attitudes. This effect has been found in numerous studies (e.g., Stoner, 1969 Mackie, 1986). Several theories, such as self-categorization theory and social comparison theory have been used to explain the phenomenon of group polarization. In the current research, an alternative framework based on optimal distinctiveness theory was proposed as a way to predict group polarization. This theory claims that individuals have two conflicting needs- the need to belong and the need to be distinct. When one of these needs is unmet, people …


The Effects Of Increasing The Risk Perception Of High-Risk Behaviors On Decision Making Among College Daily Smokers And Never-Smokers, Scott Patterson Jan 2009

The Effects Of Increasing The Risk Perception Of High-Risk Behaviors On Decision Making Among College Daily Smokers And Never-Smokers, Scott Patterson

LSU Doctoral Dissertations

Participation in high-risk behaviors, such as substance use or dangerous driving practices, is widely reported by young adults and college students. Psychosocial theories explain participation in high-risk behaviors by the effects of risk perception on the outcome of behavior. Physiological researchers assert that biological factors (such as the role of the prefrontal cortex) better account for participation in high-risk behaviors based on impulsive decision-making patterns in substance users. The current study explored the relationship between impulsive decision-making and risk perception by assessing the impact of changes in high-risk perceptions on a measure of impulsive decision-making (delay discounting task). A sample …


Signal Detection With Criterion Noise: Applications To Recognition Memory, Aaron S. Benjamin, Michael Diaz, Wee, Serena Jan 2009

Signal Detection With Criterion Noise: Applications To Recognition Memory, Aaron S. Benjamin, Michael Diaz, Wee, Serena

Research Collection School of Social Sciences

A tacit but fundamental assumption of the theory of signal detection is that criterion placement is a noise-free process. This article challenges that assumption on theoretical and empirical grounds and presents the noisy decision theory of signal detection (ND-TSD). Generalized equations for the isosensitivity function and for measures of discrimination incorporating criterion variability are derived, and the model's relationship with extant models of decision making in discrimination tasks is examined, An experiment evaluating recognition memory for ensembles of word stimuli revealed that criterion noise is not trivial in magnitude and contributes substantially to variance in the slope of the isosensitivity …


Supporting Decision Making In A Complex World, Jonathan Tall Jan 2009

Supporting Decision Making In A Complex World, Jonathan Tall

LSU Master's Theses

Recent research has questioned whether explicit thinking is necessary or even useful for complex decision making (Gladwell, 2005; Dijksterhuis & Nordgren, 2006; Newell, Wong, Cheung, & Rakow, in press). The present research approaches this issue by examining how different types of decision support facilitate/hinder performance in a diagnostic medical task. The results from 3 experiments indicate that providing an external memory aid improves performance in complex tasks. Additional support in the form of a coding procedure improved awareness of the magnitude of drug effects, but did not improve detection of negative side effects. The results suggest that while performance is …


Knowing When To Trust Others: An Erp Study Of Decision-Making After Receiving Information From Unknown People, Cheryl Boudreau, Mathew D. Mccubbins, Seana Coulson Jan 2009

To address the neurocognitive mechanisms that underlie choices made after receiving information from an anonymous individual, reaction times (Experiment 1) and event-related brain potentials (Experiment 2) were recorded as participants played 3 variants of the Coin Toss game. In this game, participants guess the outcomes of unseen coin tosses after a person in another room (dubbed “the reporter”) observes the coin toss outcomes and then sends reports (which may or may not be truthful) to participants about whether the coins landed on heads or tails. Participants knew that the reporter's interests either were aligned with their own (Common Interests), opposed …
