What counts as a decision? Predictors of perceived decision making

We examined lay perceptions of what counts as a decision. Eighty-six subjects read 10 scenarios that described clear decisions (e.g., choosing a graduate school), clear “nondecisions” (e.g., an accidental wrong turn), or ambiguous actions (e.g., eating a donut when on a diet or allowing someone else to make the decision). The subjects rated each scenario as to whether the actor had made a decision and also rated six other attributes. The scenarios were rated as clearly illustrating a decision if the actor engaged in a lot of thought and did not act reflexively. Consideration of consequences and having alternatives were moderately related to decision ratings, whereas having self-control problems and the influence of physiological drives showed little relationship with decision ratings. Thus, lay concepts of decision making differ from decision theory in that thoughtful, intentional behavior is more important in defining a decision than are decision theoretic components, such as alternatives and consequences.     

What is behind a summary-evaluation decision?

Research in psychology has reported that, among the variety of possibilities for assessment methodologies, summary evaluation offers a particularly adequate context for inferring text comprehension and topic understanding. However, grades obtained in this methodology are hard to quantify objectively. Therefore, we carried out an empirical study to analyze the decisions underlying human summary-grading behavior. The task consisted of expert evaluation of summaries produced in critically relevant contexts of summarization development, and the resulting data were modeled by means of Bayesian networks using an application called Elvira, which allows for graphically observing the predictive power (if any) of the resultant variables. Thus, in this article, we analyzed summary-evaluation decision making in a computational framework.     

When is a mental health professional competent to assess a person's decision to hasten death?

As the country continues to debate the legality of aid-in-dying, it appears inevitable that at some point there will be a need for mental health professionals to be involved in assessments of individuals asking for a hastened death. I designed this article to provide a set of guidelines that will allow both mental health professionals and potential consultees to determine if a professional has the training and expertise necessary to be a competent consultant.     

A word’s meaning affects the decision in lexical decision

The influence of an isolated word’s meaning on lexical decision reaction time (RT) was demonstrated through four experiments. Subjects in two experiments made lexical decision judgments, those in a third experiment pronounced the words used in the lexical decision task, and those in a fourth experiment quickly pronounced their first associative response to the words. Differences in lexical access time for the words were measured with the pronunciation task, and differences in meaning were assessed with the association task. Multiple regression analyses of lexical decision RT were conducted using associative RT, pronunciation RT, and other target word properties (printed frequency, length, instance dominance, and number of dictionary meanings) as predictor variables. These analyses revealed a relationship between lexical decision RT and associative RT after the effects of other variables had been partialed out. In addition, word frequency continued to have a significant relationship to lexical decision RT beyond that shared with pronunciation RT and the other variables. The results of these experiments indicate that at least some of the effect of word meaning and word frequency in lexical decision is attributable to a decision stage following lexical access.     

Narrative responsibility and moral dilemma: A case study of a family’s decision about a brain-dead daughter

A brain death case is presented and reinterpreted using the narrative approach. In the case, two Japanese parents face a dilemma about whether to respect their daughter’s desire to donate organs even though, for them, it would mean literally killing their daughter. We argue that the ethical dilemma occurred because the parents were confronted with two conflicting narratives to which they felt a “narrative responsibility,” namely, the responsibility that drives us to tell, retell, and coauthor the (often unfinished) narratives of loved ones. We suggest that moral dilemmas arise not only from conflicts between moral justifications but also from conflicts between narratives and human relationships.     

Do self-reported decision styles relate with others’ impressions of decision quality?

Research has demonstrated the usefulness of decision styles for predicting various performance-related criteria. It is still unclear, however, which particular styles are associated with a general tendency to make high-quality decisions. Participants (n = 168) completed a common measure of five decision styles, along with a measure of the traits in the five-factor model of personality. Self and peer evaluations of general decision quality were obtained as performance criteria. Results showed that specific decision styles predicted variance in both measures of decision quality. And, there was clear evidence for incremental validity for specific decision styles when self-ratings were predicted. In the context of past research, this study supports a primary focus on rational or analytical styles for understanding and predicting decision success.

Is there a neighborhood frequency effect in English? Evidence from reading and lexical decision

What is the effect of a word's higher frequency neighbors on its identification time? According to activation-based models of word identification (J. Grainger & A. M. Jacobs, 1996; J. L. McClelland & D. E. Rumelhart, 1981), words with higher frequency neighbors will be processed more slowly than words without higher frequency neighbors because of the lexical competition mechanism embodied in these models. Although a critical prediction of these models, this inhibitory neighborhood frequency effect has been elusive in studies that have used English stimuli. In the present experiments, the effect of higher frequency neighbors was examined in the lexical decision task and when participants were reading sentences while their eye movements were monitored. Results suggest that higher frequency neighbors have little, if any, effect on the identification of English words. The implications for activation-based models of word identification are discussed.     

Investigating naturalistic decision making in a simulated microworld: What questions should we ask?

Computer-simulated microworlds can provide a controlled method for investigating concepts related to naturalistic decision making (NDM). However, the extent to which these tools can be used to generate meaningful outcomes is unknown. The current study used a microworld called Networked Fire Chief (NFC) to explore the range of skills and knowledge acquired as participants gained practice on the program. The complexity of the NFC NDM environment was also explored. Twenty participants each completed 20 equivalent 5-min scenarios on NFC. Interview data, behavioral data and performance scores were collected across the trials. Results confirmed that NFC provides an environment that promotes appropriate perceptual-cognitive processing for NDM. However, performance improved to only a small extent across the 20 trials in four performance areas: speed, accuracy, efficiency and planning. In addition, the number of personal and situational factors to be considered when decision making on NFC was not comparable with real-world NDM environments. Overall, results indicated that the use of microworlds for research should be regulated by an understanding of the limitations of their applicability.     

Behaviors associated with “good” and “poor” outcomes in a simulated career decision

What career decision-making procedures enable people to make decisions that yield consequences congruent with their own values? The 40 “best” (most congruent) and 40 “worst” decision makers on the Career Decision Simulation were compared in a sample of 148 community college students. No significant differences appeared in the amount of double checking, number of occupations and information sources checked, amount of information collected, decision time required, and the proportion of information sought about high values. The “best” decision makers, however, were significantly more persistent in immediately seeking more information about an occupation that seemed to match one of their most important personal work values. Following a values-guided search appears more effective than simply searching exhaustively.     

Is the go/no-go lexical decision task an alternative to the yes/no lexical decision task?

In the go/no-go lexical decision task (LDT), participants are instructed to respond as quickly as they can when a word is presented and not to respond if a nonword is presented. By minimizing part of the response selection process in the experimental task, the impact of response decision time on the obtained lexical decision time is probably reduced relative to the standard yes/no LDT (Gordon, 1983). Experiments 1 and 2 show that the go/no-go LDT is sensitive to the effects of word frequency and associative priming--the magnitude of these effects is similar with the two tasks. More important, the go/no-go LDT has a number of advantages with respect to the "standard" yes/no LDT: It offers faster response times, more accurate responding, and fewer processing demands than does the yes/no task. Accordingly, the go/no-go task appears to be an excellent alternative to the standard yes/no task.     

When does explicit justification impair decision making?

The idea that careful analysis leads to better decisions is pervasive in research on decision making. Intriguingly, results raise the possibility that thinking about reasons for decisions before deciding may degrade decision quality. This paper reports the results of a laboratory study which examined whether task characteristics critically influence the effects of thinking about reasons on decision quality. We found that explicit reasoning degraded judgement quality, objectively measured, on an ‘intuitive’ task. However, we also found that explicit reasoning enhanced performance on an ‘analytic’ task.

Self–other decision making and loss aversion

In eight studies, we tested the prediction that making choices for others involves less loss aversion than making choices for the self. We found that loss aversion is significantly lessened among people choosing for others in scenarios describing riskless choice (Study 1), gambling (Studies 2 and 3), and social aspects of life, such as likeably and status (Studies 4a–e). Moreover, we found this pattern in relatively realistic conditions where people are rewarded for making desirable (i.e., profitable) choices for others (Study 2), when the other for whom a choice is made is physically present (Study 3), and when real money is at stake (Studies 2 and 3). Finally, we found loss aversion is moderated when factors associated with self–other differences in decision making are taken into account, such as decision makers’ construal level (Study 4a), regulatory focus (Study 4b), degree of information seeking (Study 4c), omission bias (Study 4d), and power (Study 4e).     

Rational decision‐making among male street prostitutes

This ethnographic study examines the lives of 18 young male street prostitutes. The focus of this study is to identify the benefits and liabilities associated with this activity by grounding the decision to engage in this behavior in a rational choice perspective. Benefits identified include financial gain, sexual pleasure, control of work schedule, and affection. The liabilities include fear of arrest, potential for violence, having sex with undesirable people, and not being paid for services rendered. This study demonstrates that the decision to engage in street prostitution is a complicated process that involves the weighing of the perceived benefits against the perceived risks.     

Judging the animacy of words: The influence of typicality and age of acquisition in a semantic decision task

The age at which members of a semantic category are learned (age of acquisition), the typicality they demonstrate within their corresponding category, and the semantic domain to which they belong (living, non-living) are known to influence the speed and accuracy of lexical/semantic processing. So far, only a few studies have looked at the origin of age of acquisition and its interdependence with typicality and semantic domain within the same experimental design. Twenty adult participants performed an animacy decision task in which nouns were classified according to their semantic domain as being living or non-living. Response times were influenced by the independent main effects of each parameter: typicality, age of acquisition, semantic domain, and frequency. However, there were no interactions. The results are discussed with respect to recent models concerning the origin of age of acquisition effects.
