Does Environmental Experience Shape Spatial Cognition? Frames of Reference Among Ancash Quechua Speakers (Peru)

Previous studies have shown that language contributes to humans' ability to orient using landmarks and shapes their use of frames of reference (FoRs) for memory. However, the role of environmental experience in shaping spatial cognition has not been investigated. This study addresses such a possibility by examining the use of FoRs in a nonverbal spatial memory task among residents of an Andean community in Peru. Participants consisted of 97 individuals from Ancash Quechua‐speaking households (8–77 years of age) who spoke Quechua and/or Spanish and varied considerably with respect to the extent of their experience in the surrounding landscape. The results demonstrated that environmental experience was the only factor significantly related to the preference for allocentric FoRs. The study thus shows that environmental experience can play a role alongside language in shaping habits of spatial representation, and it suggests a new direction of inquiry into the relationships among language, thought, and experience.     

Improving Accuracy on Bayesian Inference Problems Using a Brief Tutorial

Research suggests that most people struggle when asked to interpret the outcomes of diagnostic tests such as those presented as Bayesian inference problems. To help people interpret these difficult problems, we created a brief tutorial, requiring less than 10 minutes, that guided participants through the creation of an aid (either graph or table) based on an example inference problem and then showed the correct way to calculate the positive predictive value of the problem (i.e., likelihood that positive tests correctly indicate presence of condition). Approximately 70% of those in each training condition found the correct response on at least one problem in the format for which they were trained. Just under 55% of those in the control condition (i.e., no training) were able to find the correct response on at least one table or graph problem. We demonstrated a relationship between numeracy and performance on both problem formats, although we did not find evidence for a relationship between graph literacy and performance for either problem format. Potential improvements to and applications of the tutorial are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

A dual systems theory of incontinent action

In philosophy of action, we typically aim to explain action by appealing to conative attitudes whose contents are either logically consistent propositions or can be rendered as such. Call this “the logical criterion.” This is especially difficult to do with clear-minded, intentional incontinence since we have to explain how two judgments can have non-contradicting contents yet still aim at contradictory outcomes. Davidson devises an innovative way of doing this but compromises his ability to explain how our better judgments can cause our continent behaviors. In this essay, I preserve Davidson’s approach to the logical criterion but deviate from his broader theory of action by developing a default-interventionist dual systems theory of action. To do this, I focus on the dynamical relationship between System 1 and System 2: (1) the logical construction of value judgments in System 2 from System 1 and (2) the imaginative construction of non-propositional conative attitudes in System 1 from System 2. I draw on Street’s Humean constructivism and Peacocke’s theory of imagination for logical and imaginative construction, respectively. Within this framework, I provide a new definition of continence and incontinence that satisfies the logical criterion and explains how our better judgments can cause our continent behaviors.     

Smith’s practicality requirement meets dual-process models of moral judgment

In The Moral Problem, Michael Smith argues that only motivational internalists can offer an adequate explanation of why changes in moral judgment tend to be accompanied by changes in motivation in morally virtuous people. Smith argues that the failure of motivational externalism to account for this phenomenon amounts to a reductio of the view. In this paper, I draw on dual-process models of moral judgment to develop an externalist response to Smith’s argument. The key to my proposal is that motivationally efficacious states are often the source of our moral judgments, and changes in judgment are typically the result of changes in these states. However, moral judgments can also be formed via an alternative pathway that does not necessarily affect motivation, and so motivation and judgment can come apart. This response not only defuses Smith’s objections to externalism, but challenges Smith to square his internalist proposal with the empirical details of moral judgment.     

The cognitive reflection test revisited: exploring the ways individuals solve the test

Individuals’ propensity not to override the first answer that comes to mind is thought to be a crucial cause behind many failures in reasoning. In the present study, we aimed to explore the strategies used and the abilities employed when individuals solve the cognitive reflection test (CRT), the most widely used measure of this tendency. Alongside individual differences measures, protocol analysis was employed to unfold the steps of the reasoning process in solving the CRT. This exploration revealed that there are several ways people solve or fail the test. Importantly, 77% of the cases in which reasoners gave the correct final answer in our protocol analysis, they started their response with the correct answer or with a line of thought which led to the correct answer. We also found that 39% of the incorrect responders reflected on their first response. The findings indicate that the suppression of the first answer may not be the only crucial feature of reflectivity in the CRT and that the lack of relevant knowledge is a prominent cause of the reasoning errors. Additionally, we confirmed that the CRT is a multi-faceted construct: both numeracy and reflectivity account for performance. The results can help to better apprehend the “whys and whens” of the decision errors in heuristics and biases tasks and to further refine existing explanatory models.     

Incidental emotions have a greater impact on the logicality of less proficient reasoners

Previous research shows differences in reasoning about emotional and neutral stimuli. A common explanation hypothesised for this effect is that emotion incurs an additional cognitive load. If this is the case, incidental emotion should have a greater impact on the reasoning of less proficient reasoners, and when items are more difficult, because a greater proportion of available cognitive resources must be allocated to the task. We manipulated the emotional value of reasoning stimuli using conditioning and with the simultaneous presentation of images. The deleterious effect of emotion on logicality was greater for less proficient reasoners. There was also some indication that the effect of emotion may be more pronounced for more difficult items. Physiological responses and affective evaluations of the stimuli were similar across groups, irrespective of reasoning proficiency. Results provide some support for the hypothesis that the impact of emotion occurs through increased cognitive load.     

The modulation of disjunctive assertions

The theory of mental models postulates that disjunctions of the sort, A or B, where A and B are sensible everyday clauses, have a core meaning that allows an inclusive interpretation, referring to three possibilities: A and not-B, not-A and B, and A and B. The meaning of the clauses and knowledge can modulate this meaning by blocking the construction of at least one model of a possibility—for example, “Rui is playing tennis or he is surfing” blocks the model of Rui doing both activities. This theory is implemented in a computer program. Three experiments investigated the core interpretation and interpretations in which the contents of the clauses should block the model of A and B (as in the preceding example), the model of A and not-B, or the model of not-A and B. In Experiment 1, the participants listed the possibilities for each of the four sorts of disjunction. The results corroborated the predicted modulations. In Experiment 2, these predicted interpretations governed the conclusions that participants accepted from disjunctions and categorical premises. In Experiment 3, the predicted interpretations yielded reliable effects on the conclusions that the participants drew for themselves. We relate these results to theories of reasoning.     

Advice conditionals about tips and warnings: interpretations and inferences

Two experiments examine how people interpret and reason about advice conditionals, such as tips, for example, “if you study more your grades will improve”, and warnings, for example, “if you stop exercising you will gain weight”. Experiment 1 showed that when participants reason about whether a tip or warning could be true in different situations, their judgments correspond to a biconditional or conditional interpretation on about half of all trials, but to an enabling or tautology interpretation on many others. Experiment 2 showed that participants make few modus ponens and tollens inferences from tips and warnings, and more modus ponens inferences from tips than warnings. The implications for alternative theories are discussed.
