On the Validity of Idiographic and Generic Self‐Concept Implicit Association Tests: A Core‐Concept Model

We present a core‐concept model (CCM) suggesting that stimulus centrality is an important factor in category representations in implicit measures. We tested the hypothesis that idiographic stimuli (first name, birthday) are more central and therefore assess self‐concept in Implicit Association Tests (IATs) more validly than generic and nonspecific stimuli (me, you). Superior validity of the idiographic variant emerged across three different domains of self‐concept. First, an idiographic self‐esteem IAT displayed higher correlations than a generic IAT with self‐assessments and observer‐assessments of self‐esteem. Second, an idiographic body scheme‐IAT predicted subjective ratings of body image and objective body‐mass index. Third, an idiographic aggressiveness‐IAT had higher incremental validity for unprovoked aggression when interacting with explicit measures of aggressiveness. We conclude that idiographic stimuli focus participants' attention on the core features of the self, hence, tapping into self‐related associations to a stronger degree than generic stimuli.

Mindfulness meditation counteracts self-control depletion

Mindfulness meditation describes a set of different mental techniques to train attention and awareness. Trait mindfulness and extended mindfulness interventions can benefit self-control. The present study investigated the short-term consequences of mindfulness meditation under conditions of limited self-control resources. Specifically, we hypothesized that a brief period of mindfulness meditation would counteract the deleterious effect that the exertion of self-control has on subsequent self-control performance. Participants who had been depleted of self-control resources by an emotion suppression task showed decrements in self-control performance as compared to participants who had not suppressed emotions. However, participants who had meditated after emotion suppression performed equally well on the subsequent self-control task as participants who had not exerted self-control previously. This finding suggests that a brief period of mindfulness meditation may serve as a quick and efficient strategy to foster self-control under conditions of low resources.     

Impulses got the better of me: alcohol moderates the influence of implicit attitudes toward food cues on eating behavior

This study shows that alcohol consumption enhances the prediction of candy consumption by implicit attitudes and at the same time decreases the predictive validity of cognitive restraint standards. Female participants were assigned to either an alcohol or a control condition and were then given an opportunity to taste candies. For participants in the alcohol condition, candy consumption was uniquely predicted by previously assessed implicit attitudes toward the candy. In contrast, candy consumption was primarily predicted by cognitive restraint (Three Factor Eating Questionnaire) in the control condition. Moreover, participants who consumed alcohol ate significantly more candy at the group level. These results indicate that alcohol increases the behavioral impact of impulsive determinants on eating behavior while disrupting the behavioral impact of reflective determinants. They further demonstrate that measures of implicit attitudes toward tempting stimuli add incremental validity for the prediction of self-control outcomes.     

What mediation analysis can (not) do

The present article is concerned with a common misunderstanding in the interpretation of statistical mediation analyses. These procedures can be sensibly used to examine the degree to which a third variable (Z) accounts for the influence of an independent (X) on a dependent variable (Y) conditional on the assumption that Z actually is a mediator. However, conversely, a significant mediation analysis result does not prove that Z is a mediator. This obvious but often neglected insight is substantiated in a simulation study. Using different causal models for generating Z (genuine mediator, spurious mediator, correlate of the dependent measure, manipulation check) it is shown that significant mediation tests do not allow researchers to identify unique mediators, or to distinguish between alternative causal models. This basic insight, although well understood by experts in statistics, is persistently ignored in the empirical literature and in the reviewing process of even the most selective journals.

Realizing what might be

Schulz has shown that the suppositional view of indicative conditionals leads to a corresponding view of epistemic modals. But his case backfires: the resulting theory of epistemic modals gets the facts wrong, and so we end up with a good argument against the suppositional view. I show how and why a dynamic view of indicative conditionals leads to a better theory of epistemic modals.     

The time course of face matching for featural and relational image manipulations

It was found recently that horizontal and vertical relationships of facial features are differently vulnerable to inversion (Goffaux & Rossion, 2007). When faces are upside down manipulations of vertical relations are difficult to detect, while only moderate performance deficits are found for manipulations of horizontal relations, or when features differ. We replicate the findings of Goffaux and Rossion, and record the temporal courses of face matching performance and the effects of inversion. For vertical relations and featural changes inversion effects arise immediately, starting with the first 50 ms of processing. For horizontal relations inversion effects are absent at brief timings, but arise later, after about 200 ms. The final magnitudes of inversion effects are different in all three conditions, reaching 23.4% for vertical displacement, 10.7% for feature replacement, and 5.8% for horizontal displacement. Our results underline the special status of horizontal in contrast to vertical feature relations, and indicate that local and global configural information is handled in parallel by specific routines, as proposed recently (Senunkova & Barton, 2008).     

Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.
