What the Wise Ought Believe: A Voluntarist Interpretation of Hume's General Rules

This paper advances an interpretation of what Hume called ‘the general rules’: natural principles of belief-formation that nevertheless can be augmented via reflection. According to Hume, reflection is, in part, what separates the wise from the vulgar. In this paper, I argue that for Hume being wise must therefore be, to some degree, voluntary. Hume faced a significant problem in attempting to reconcile his epistemic normativity, i.e. his claims about what we ought to believe, with his largely involuntarist theory of the mind. Reflection on the General Rules, and an interpretation of that reflection as voluntary, helps explain not only Hume's theory of belief, but also how he hoped to reconcile epistemic normativity with naturalism about the mental.     

Reasons for withdrawing belief in vivid autobiographical memories

Previous studies have shown that many people hold personal memories for events that they no longer believe occurred. This study examines the reasons that people provide for choosing to reduce autobiographical belief in vividly recollected autobiographical memories. A body of non-believed memories provided by 374 individuals was reviewed to develop a qualitatively derived categorisation system. The final scheme consisted of 8 major categories (in descending order of mention): social feedback, event plausibility, alternative attributions, general memory beliefs, internal event features, consistency with external evidence, views of self/others, personal motivation and numerous sub-categories. Independent raters coded the reports and judged the primary reason that each person provided for withdrawing belief. The nature of each category, frequency of category endorsement, category overlap and phenomenological ratings are presented, following which links to related literature and implications are discussed. This study documents that a wide variety of recollective and non-recollective sources of information influence decision-making about the occurrence of autobiographical events.     

Prevalence-based decisions undermine visual search

In visual search, observers make decisions about the presence or absence of a target based on their perception of a target during search. The present study investigated whether decisions can be based on observers’ expectation rather than perception of a target. In Experiment 1, participants were allowed to make target-present responses by clicking on the target or, if the target was not perceived, a target-present button. Participants used the target-present button option more frequently in difficult search trials and when target prevalence was high. Experiment 2 and 3 employed a difficult search task that encouraged the use of prevalence-based decisions. Target presence was reported faster when target prevalence was high, indicating that decisions were, in part, cognitive, and not strictly perceptual. A similar pattern of responses were made even when no targets appeared in the search (Experiment 3). The implication of these prevalence-based decisions for visual search models is discussed.     

Individual differences in strategies for syllogistic reasoning

Current theories of reasoning such as mental models or mental logic assume a universal cognitive mechanism that underlies human reasoning performance. However, there is evidence that this is not the case, for example, the work of Ford (1995), who found that some people adopted predominantly spatial and some verbal strategies in a syllogistic reasoning task. Using written and think-aloud protocols, the present study confirmed the existence of these individual differences. However, in sharp contrast to Ford, the present study found few differences in reasoning performance between the two groups, in terms of accuracy or type of conclusion generated. Hence, reasoners present an outward appearance of ubiquity, despite underlying differences in reasoning processes. These findings have implications for theoretical accounts of reasoning, and for attempts to model reasoning data. Any comprehensive account needs to account for strategic differences and how these may develop in logically untrained individuals.     

Executive functions in decision making: An individual differences approach

This individual differences study examined the relationships between three executive functions (updating, shifting, and inhibition), measured as latent variables, and performance on two cognitively demanding subtests of the Adult Decision Making Competence battery: Applying Decision Rules and Consistency in Risk Perception. Structural equation modelling showed that executive functions contribute differentially to performance in these two tasks, with Applying Decision Rules being mainly related to inhibition and Consistency in Risk Perception mainly associated to shifting. The results suggest that the successful application of decision rules requires the capacity to selectively focus attention and inhibit irrelevant (or no more relevant) stimuli. They also suggest that consistency in risk perception depends on the ability to shift between judgement contexts.     

There is more than obeying display rules: Service employees’ motives for emotion regulation in customer interactions

Although research has focused on how service employees regulate their emotions, few studies have explored why they do so. In this article, we first described which kinds of motives for emotion regulation exist in customer interactions. Second, we investigated how the motives are related to four emotion regulation strategies. The application of an explorative approach resulted in a list of 10 motives, which could be classified into the three motive categories: pleasure, prevention, and instrumental. Hierarchical linear modelling of 421 reported service interactions from a diary study revealed that the motive categories were differently related to the emotion regulation strategies. Motives of the instrumental category were only significantly positively related to surface acting. Motives of the pleasure category were positively related to deep acting and automatic regulation as well as negatively related to surface acting and emotional deviance. Motives of the prevention category were positively related to deep acting, surface acting, and emotional deviance as well as negatively related to automatic regulation. These results can be used by organizations not only to enhance the motivation of employees towards emotion regulation, but also towards more authentic emotional expressions.     

Linking cognitive and reaching trajectories via intermittent movement control

Theories of decision-making have traditionally been constrained by reaction time data. A limitation of reaction time data, particularly for studying the temporal dynamics of cognitive processing, is that they index only the endpoint of the decision making process. Recently, physical reaching trajectories have been used as proxies for underlying mental trajectories through decision space. We suggest that this approach has been oversimplified: while it is possible for the motor control system to access the current state of the evidence accumulation process, this access is intermittent. Instead, we demonstrate how a model of arm movements that assumes intermittent, not continuous, access to the decision process is sufficient to describe the effects of stimulus quality and viewing time in curved reaching movements.

In this article, I juxtapose Pentecostal churches with youth gangs, two popular barrio institutions that at first glance appear to be irreconcilable but when considered together evince organic parallels that reveal important insights into contemporary life in urban poverty. Reflecting on ethnographic data from the Dominican Republic and elsewhere, I argue that due to an analogous ritualization of everyday life – through rigorous rules and clearly defined consequences for breaking them – both Pentecostal churches and youth gangs, despite their ostensible differences, afford a unique kind of freedom in constraint, and by providing reliable spaces of predictability, control, and mastery, have become popular stages for managing the precariousness of barrio life in late modernity.
