CONSCIOUS AND UNCONSCIOUS PROCESSES IN DECISION MAKING 1 Conscious and Unconscious Processes in Decision Making (original) (raw)

Unconscious influences of, not just on, decision-making

Behavioral and Brain Sciences, 2014

To what extent do we know our own minds when making decisions? Variants of this question have preoccupied researchers in a wide range of domains, from mainstream experimental psychology (cognition, perception, social behavior) to cognitive neuroscience and behavioral economics. A pervasive view places a heavy explanatory burden on an intelligent cognitive unconscious, with many theories assigning causally effective roles to unconscious influences. This article presents a novel framework for evaluating these claims and reviews evidence from three major bodies of research in which unconscious factors have been studied: multiple-cue judgment, deliberation without attention, and decisions under uncertainty. Studies of priming (subliminal and primes-to-behavior) and the role of awareness in movement and perception (e.g., timing of willed actions, blindsight) are also given brief consideration. The review highlights that inadequate procedures for assessing awareness, failures to consider artifactual explanations of "landmark" results, and a tendency to uncritically accept conclusions that fit with our intuitions have all contributed to unconscious influences being ascribed inflated and erroneous explanatory power in theories of decision making. The review concludes by recommending that future research should focus on tasks in which participants' attention is diverted away from the experimenter's hypothesis, rather than the highly reflective tasks that are currently often employed.

Does unconscious thought improve complex decision making?

Psychological Research Psychologische Forschung, 2009

In a recent study, Dijksterhuis et al. (Science 311:1005, 2006) reported that participants were better at solving complex decisions after a period of unconscious thought relative to a period of conscious thought. They interpreted their results as an existence proof of powerful unconscious deliberation mechanisms. In the present report, we used a similar experimental design with an additional control, immediate condition, and we observed that participants produced as good (and even descriptively better) decisions in this condition than in the "unconscious" one, hence challenging the initial interpretation of the authors. However, we still obtained lower performances in the "conscious" relative to the "immediate" condition, suggesting that the initial result of Dijksterhuis et al. was not due to the action of powerful unconscious thought processes, but to the apparent disadvantage of further conscious processing. We provide an explanation for this observation on the basis of current models of decision making. It is Wnally concluded that the beneWt of unconscious thought in complex decision making is still a controversial issue that should be considered cautiously.

Unconscious processing of information in dynamic decision-making–an experimental approach

2008

The purpose of the paper is to investigate the effects of unconscious versus conscious ways of making decisions in a dynamic decision-making task. An experimental setting is used to study this question; three experimental groups are distinguished: immediate decision-making (only limited time for cognitive processing), considered decisionmaking (time for conscious processing), and distracted decision-making (time for unconscious processing). As experimental stimulus, a simulator based on the Kaibab Plateau model is employed. Although more than 100 subjects have been tested so far, group differences are not significant for most data examined. Implications comprise the improvement of the experiment in order to derive at more substantial results. The value of the paper lies in the fact that it connects to a recent discussion in psychology and transfers it into a domain in the core interest of the system dynamics community: decision-making in situations with dynamic complexity.

Is the unconscious, if it exists, a superior decision maker?

Boundary conditions on unconscious thought in complex decision making

2008

Should individuals delegate thinking about complex choice problems to the unconscious? We tested two boundary conditions on this suggestion. First, we found that in a decision environment similar to those studied previously, self-paced conscious thought and unconscious thought had similar advantages over conscious thought constrained to a long fixed time interval in terms of identifying the option with the highest number of positive outcomes. Second, we found that self-paced conscious thought performed better than unconscious thought in a second decision environment where performance depended to a greater extent on magnitudes of the attributes. Thus, we argue that it is critical to take into account the interaction of forms of processing with task demands (choice environments) when considering how to approach complex choice problems.

González-Vallejo, C., Stewart, T. R., Lassiter, D., & Weindhardt, J. M. (in press). How necessary is the unconscious as a predictive, explanatory, or prescriptive construct? Behavioral and Brain Sciences

Behavioral and Brain Sciences

We elucidate the epistemological futility of using concepts such as unconscious thinking in research. Focusing on Newell and Shanks's use of the lens model as a framework, we clarify issues with regard to unconscious-thought theory (UTT) and self-insight studies. We examine these key points: Brunswikian psychology is absent in UTT; research on self-insight did not emerge to explore the unconscious; the accuracy of judgments does not necessitate the unconscious; and the prescriptive claim of UTT is unfounded.

Testing the Advantages of Conscious vs. Unconscious Thought for Complex Decisions in a Distraction Free Paradigm

SSRN Electronic Journal, 2016

Testing the Advantages of Conscious vs. Unconscious Thought for Complex Decisions in a Distraction Free Paradigm * In this study we test predictions from Unconscious Thought Theory (UTT) that unconscious thought will lead to better decision making in complex decision tasks relative to conscious thought. Different from prior work testing this prediction, we use a method of manipulating conscious and unconscious thinking that is free from distraction. Specifically, we use a 3-week protocol to experimentally induce adverse sleep and circadian states, both of which should reduce deliberative, conscious thinking and therefore increase the relative importance of more automatic unconscious processes. Our findings fail to support UTT predictions and instead coalesce with other replication attempts that cast doubt on the superiority of unconscious processing in complex decision making.

The unconscious thought advantage: Further replication failures from a search for confirmatory evidence

Judgment and decision making

According to the deliberation without attention (DWA) hypothesis, people facing a difficult choice will make a better decision after a period of distraction than after an equally long period of conscious deliberation, an effect referred to as the unconscious thought advantage (UTA). The status of the DWA hypothesis is controversial, as many studies have tried but failed to replicate the UTA. Here, we report a series of experiments that sought to identify the conditions under which the UTA can be replicated. Our starting point was a recent meta-analysis that identified the conditions under which the UTA was strongest in previous studies. Using a within-subjects design and a task that met each of these conditions, we failed to replicate the UTA. Based on closer inspection of previous methods and findings, we then examined some additional factors that could be important for replicating the UTA, including mental fatigue and choice complexity. This was to no avail, as the results reveale...

Not Merely Experiential: Unconscious Thought Can Be Rational

Frontiers in Psychology, 2017

Individuals often form more reasonable judgments from complex information after a period of distraction vs. deliberation. This phenomenon has been attributed to sophisticated unconscious thought during the distraction period that integrates and organizes the information (Unconscious Thought Theory; Dijksterhuis and Nordgren, 2006). Yet, other research suggests that experiential processes are strengthened during the distraction (relative to deliberation) period, accounting for the judgment and decision benefit. We tested between these possibilities, hypothesizing that unconscious thought is distinct from experiential processes, and independently contributes to judgments and decisions during a distraction period. Using an established paradigm, Experiment 1 (N = 319) randomly induced participants into an experiential or rational mindset, after which participants received complex information describing three roommates to then consider consciously (i.e., deliberation) or unconsciously (i.e., distraction). Results revealed superior roommate judgments (but not choices) following distraction vs. deliberation, consistent with Unconscious Thought Theory. Mindset did not have an influence on roommate judgments. However, planned tests revealed a significant advantage of distraction only within the rational-mindset condition, which is contrary to the idea that experiential processing alone facilitates complex decision-making during periods of distraction. In a second experiment (N = 136), we tested whether effects of unconscious thought manifest for a complex analytical reasoning task for which experiential processing would offer no advantage. As predicted, participants in an unconscious thought condition outperformed participants in a control condition, suggesting that unconscious thought can be analytical. In sum, the current results support the existence of unconscious thinking processes that are distinct from experiential processes, and can be rational. Thus, the experiential vs. rational nature of a process might not cleanly delineate conscious and unconscious thought.
