Does the cognitive reflection test measure cognitive reflection? A mathematical modeling approach

We used a mathematical modeling approach, based on a sample of 2,019 participants, to better understand what the cognitive reflection test (CRT; Frederick In Journal of Economic Perspectives, 19, 25–42, 2005) measures. This test, which is typically completed in less than 10 min, contains three problems and aims to measure the ability or disposition to resist reporting the response that first comes to mind. However, since the test contains three mathematically based problems, it is possible that the test only measures mathematical abilities, and not cognitive reflection. We found that the models that included an inhibition parameter (i.e., the probability of inhibiting an intuitive response), as well as a mathematical parameter (i.e., the probability of using an adequate mathematical procedure), fitted the data better than a model that only included a mathematical parameter. We also found that the inhibition parameter in males is best explained by both rational thinking ability and the disposition toward actively open-minded thinking, whereas in females this parameter was better explained by rational thinking only. With these findings, this study contributes to the understanding of the processes involved in solving the CRT, and will be particularly useful for researchers who are considering using this test in their research.     

What does it take for context to support action memory?

Previous research on the relation between context and action memory has given ambiguous results. Some experiments have found positive context effects, whereas other experiments have failed to demonstrate a context effect in action memory. Under nonmotor encoding conditions orderly action-locus pairings have been found to yield better recall than random pairings, this not being the case with motor encoding (Helstrup, 1989 a ). Three new experiments explored whether memory for loci could be linked with memory for action–using modified replications. The first experiment provided item-specific reasons for the action-locus connections, whereas the second experiment used a whole-list relational context task. Both experiments indicated that contexts can influence action memory also under enactment conditions, with strongest effect for whole-list contexts. The third experiment demonstrated how a positive context effect can be removed when the functional value of whole-list relational support cues is reduced.     

Is the matching familiar figures test a measure of cognitive style? A warning for users

A probabilistic model of reflection-impulsivity as measured by the Matching Familiar Figures Test (MFFT) is presented and tested on 77 fourth graders. In testing the model two groups emerged, a random response group (n = 22) and a cognitive response group (n = 55), who use the evaluation process. Correlations among latencies, total errors, initial errors, school-scores, and IQs were compared for our total sample and the two groups. The correlation of MFFT latencies and errors disappeared for the random-response group and new correlations with errors appeared while the cognitive response group kept a statistically significant correlation of latencies with errors and no other error correlation was shown. This last group was classified by Kagan's median-split procedure showing that most reflective subjects kept their classification. Preliminary results suggest a reinterpretation of reflection-impulsivity literature, especially as related to the impulsive style.     

What measure of interpersonal dependency predicts changes in social support?

One of the most intriguing characteristics of interpersonal dependency is its ability to predict elevated levels of social support. Yet studies of interpersonal dependency use various measures to assess this effect. In this study, I compared 3 commonly used measures of interpersonal dependency in terms of their prediction of social support: Hirschfield's Interpersonal Dependency Inventory (IDI; Hirschfeld et al., 1977), the dependency factor of the Depressive Experiences Questionnaire (DEQ; Blatt, D'Afflitti, & Quinlan, 1976), and the Dependency subscale of the Personal Style Inventory (PSI; Robins et al., 1994). A total of 152 undergraduates were administered these measures as well as measures of depressive symptoms and social support a week prior to their first exam period and a week after this period (interval time = 8 weeks). DEQ-dependency predicted an increase in social support, whereas PSI-Dependency and IDI predicted a decrease in social support over time. DEQ-dependency appears to capture better than the other 2 measures the dialectic tension between risk and resilience in interpersonal dependency.     

A metric for the cognitive map: found at last?

A network of brain areas collectively represent location, but the underlying nature of this "cognitive map" has remained elusive. A recent study reports that the activity patterns of some entorhinal cortical neurons form a remarkably regular array of evenly spaced peaks across the surface of the environment. These "grid cells" might be the basis of a metric used for calculating position, and their discovery could greatly advance our understanding of how navigational computations are performed.     

The dot-probe task to measure emotional attention: A suitable measure in comparative studies?

For social animals, attending to and recognizing the emotional expressions of other individuals is of crucial importance for their survival and likely has a deep evolutionary origin. Gaining insight into how emotional expressions evolved as adaptations over the course of evolution can be achieved by making direct cross-species comparisons. To that extent, experimental paradigms that are suitable for investigating emotional processing across species need to be developed and evaluated. The emotional dot-probe task, which measures attention allocation toward emotional stimuli, has this potential. The task is implicit, and subjects need minimal training to perform the task successfully. Findings in nonhuman primates, although scarce, show that they, like humans, have an attentional bias toward emotional stimuli. However, the wide literature on human studies has shown that different factors can have important moderating effects on the results. Due to the large heterogeneity of this literature, these moderating effects often remain unnoticed. We here review this literature and show that subject characteristics and differences in experimental designs affect the results of the dot-probe task. We conclude with specific recommendations regarding these issues that are particularly relevant to take into consideration when applying this paradigm to study animals.     

Is Understanding Epistemic in Nature?

Is understanding epistemic in nature? Does a correct account of what constitutes understanding of a concept mention epistemological notions such as knowledge, justification or epistemic rationality? We defend the view that understanding is epistemic in nature – we defend epistemological conceptions of understanding. We focus our discussion with a critical evaluation of Tim Williamson's challenges to epistemological conceptions of understanding in The Philosophy of Philosophy. Against Williamson, we distinguish three kinds of epistemological conceptions and argue that Williamson's arguments succeed against only the most heavily committed kind, and leave the less heavily committed kinds untouched. Further, we argue that Williamson's elaboration of lessons from his arguments point in a direction opposite of his own conclusions and give vivid articulation and support to epistemological conceptions. We suggest also that skepticism about Williamson's larger metaphilosophical conclusions – according to which understanding plays no special role in the epistemology of philosophy – may be in order.     

The mouse attentional-set-shifting task: A method for assaying successful cognitive aging?

Humans exhibit considerable variance in cognitive decline with age, with some exhibiting little disruption and others becoming significantly impaired. In aged rodents, individual differences in spatial memory have been used to identify putative compensatory mechanisms underlying successful hippocampal aging. However, there are few parallel rodent models of cognitive decline in frontal-cortex-mediated functions. We tested the hypothesis that, like aged humans, aged mice would exhibit greater variance in executive function measures, as compared with young mice. We examined the performance of young and aged C57BL/6N mice in the attentional-set-shifting task. Whereas young and old mice did not differ on trials-to-criterion performance, aged mice exhibited significantly greater variance in mean correct latency—selective to the extradimensional shifting stage—as compared with their younger counterparts. Thus, this task may be used to identify mechanisms underlying individual differences in decline of frontal-mediated performances with age.     

Zero-sum beliefs shape advantaged allies’ support for collective action

Three studies (N₁ = 1,019; N₂ = 312; N₃ = 494) tested whether seeing intergroup relations as inherently antagonistic shaped advantaged social groups’ allyship intentions. More specifically, we tested whether endorsing zero-sum beliefs related to their willingness to support system-challenging and system-supporting collective action. Zero-sum beliefs were negatively correlated with system-challenging and positively correlated with system-supporting collective action intentions. Zero-sum beliefs were more common among advantaged than disadvantaged groups and translated into lower allyship intentions. Advantaged group members with higher levels of zero-sum beliefs were also more likely to experience anger and fear when considering the demographic racial shift in the United States. Increased fear was associated with greater support for system-supporting and lower support for system-challenging collective action. We find consistent evidence that advantaged group members see intergroup relations as a zero-sum game and that these beliefs are negatively related to their intentions to become allies.     

Schedule control, supervisor support and work engagement: A winning combination for workers in hourly jobs?

The changing natures of both work and the lives of the U.S. workforce have created an array of challenges for organizations attempting to foster work engagement. To accommodate the work and family needs of an increasingly diverse workforce, many firms are offering flexible work solutions to employees. However, the distribution of these types of organizational resources is unequal, with workers in lower-wage hourly jobs having the least access to any form of flexibility. The purpose of this paper is to examine the relationship of schedule control, as a form of flexible work practice, and work engagement among workers employed in hourly retail jobs. Authors tested a model whereby the relationship between schedule control and work engagement is mediated by schedule satisfaction and perceived supervisor support. A sample of 1343 full-time hourly retail workers was used to address the study's purpose. Hypothesized relationships were fully or partially supported. Implications for research and practice are discussed.     

Recording achievement and action planning: A basis for progression to higher education?

A questionnaire developed to establish experience of recording achievement and action planning was administered to 812 students commencing undergraduate study in 1994. While one-to-one tutorial opportunities appeared to be a key element which was associated with positive outcomes, more than one-third of the sample group reported no such opportunities. For the majority of students, recording achievement was not seen as a means of planning and managing learning. Those who participated in a process which they scored highly on criteria associated with quality practice, however, were more likely to see the process as having a role in learning management and were also more confident that they could identify achievements and present evidence for these achievements. Similarly, students involved in planning future actions were more confident when it came to setting goals within higher education. Some implications of these results for guidance practice are highlighted.     

Career support for migrants: Transformation or adaptation?

The complex interfaces created by migration not only challenge core beliefs about the purpose of career guidance and counseling but also about the precise nature and level of the support required for migrants. However, the issue has had little academic attention. While traditional theories informing the practice of career guidance and counseling implicitly reflect a commitment to social equality, they were developed in relatively homogenous Western capitalist contexts that were strongly individualized, masculine, secular, action and future focused. As career guidance and counseling services in more individualized countries seek to meet the needs of a growing number of clients from more collectivist cultures, the universal relevance of such models is increasingly open to challenge. This article explores three core challenges posed by migration for the theory and practice of career guidance and counseling. The first relates to the very purpose of these types of services for migrants; the second, to the way in which migration requires a realignment of the relationship of theory with practice; and the third relates to the need to redefine service delivery models for this client group. The extent to which notions of “quality” in services are culturally dependent will also be considered, together with the potential for general service improvements being stimulated by the provision of high quality services for migrants.     

Is one item an adequate measure of cognitive learning?

While the "leaning loss" scale is a valid means of estimating cognitive learning, the test is valid only when used as designed-with two items.     

When does a referent public problem affect financial and political support for public action?

In three studies we examined the willingness to support action to remedy a public problem. In Study 1 and Study 2, people were asked whether they would financially contribute to solution of a public problem. In Study 3, people were asked whether they would sign a petition to support a public action. The aim was to test whether the willingness to support solution of a public problem is affected by the type of problem that is used as the referent. We hypothesized that the willingness to support a public action is lower when evaluated in the context of a high‐ as opposed to a low‐importance referent problem (importance contrast effect). We also hypothesized that the importance contrast effect is tied to the perceived relatedness between the target and referent problems. The importance contrast effect should be found only when the two problems relate to different category domains. The findings bear out this prediction. Copyright © 2007 John Wiley & Sons, Ltd.     

Antiegalitarians for affirmative action? When social dominance orientation is positively related to support for egalitarian social policies

Previous research has found that people high in social dominance orientation (i.e., antiegalitarians) generally oppose affirmative action policies. We propose that antiegalitarians may be less opposed to strong affirmative action policies because such policies may be perceived to ultimately strengthen racial hierarchies. Studies 1 and 2 demonstrate that antiegalitarian individuals are less opposed to affirmative action policies, as compared to egalitarian individuals, when such policies strongly weigh minority status in selection decisions. Study 3 provides evidence that antiegalitarians lessen their opposition to strong policies only when such policies are believed to enhance racial hierarchies through the recruitment of minorities that remain at the bottom of organizational hierarchies. Theoretical, political, and organizational implications are discussed.     

Simplicity: a unifying principle in cognitive science?

Much of perception, learning and high-level cognition involves finding patterns in data. But there are always infinitely many patterns compatible with any finite amount of data. How does the cognitive system choose 'sensible' patterns? A long tradition in epistemology, philosophy of science, and mathematical and computational theories of learning argues that patterns 'should' be chosen according to how simply they explain the data. This article reviews research exploring the idea that simplicity drives a wide range of cognitive processes. We outline mathematical theory, computational results and empirical data that underpin this viewpoint.
