Frege,Dedekind, and the Origins of Logicism

This paper has a two-fold objective: to provide a balanced, multi-faceted account of the origins of logicism; to rehabilitate Richard Dedekind as a main logicist. Logicism should be seen as more deeply rooted in the development of modern mathematics than typically assumed, and this becomes evident by reconsidering Dedekind's writings in relation to Frege's. Especially in its Dedekindian and Fregean versions, logicism constitutes the culmination of the rise of ‘pure mathematics’ in the nineteenth century; and this rise brought with it an inter-weaving of methodological and epistemological considerations. The latter aspect illustrates how philosophical concerns can grow out of mathematical practice, as opposed to being imposed on it from outside. It also sheds new light on the legacy and the lasting significance of logicism today.     

Boundaries of Citizenship Behavior: Curvilinearity and Context in the Citizenship and Task Performance Relationship

Resource allocation, attentional capacity, and role theories all suggest that the well‐documented linear relationship between citizenship behavior and task performance may be more complex than previously believed. In a study of 352 incumbents, we develop hypotheses that propose a curvilinear effect of employee citizenship on task performance. We further argue that this nonmonotonic relationship is different across the targets of citizenship performance and is moderated by several factors from the task context. Results support the curvilinear assertion, indicating that the relationship with task performance inflects when citizenship is more frequently performed. These diminishing returns are amplified when the target of citizenship is the organization compared to the individual. Findings further reveal that the task context elements of accountability and autonomy moderate the curvilinear relationship, whereas ambiguity does not. Implications for a reappraisal of the citizenship–task performance relationship are discussed.     

Deviance,norms, and social reaction

The author suggests a scheme that attempts to resolve some of the conceptual problems and dilemmas that Meier argues persist in the sociology of deviant behavior. He proposes that a distinction be made not only between the normative and the reactive perspectives toward deviance, but also between “hard” and “soft” varieties of the reactive perspective. The normative perspective has limitations and drawbacks—as does a liberal (or “hard") reading of reactive theory. The “soft” variety of the reactive perspective attempts to surmount these limitations and drawbacks.     

Extending a Multilab Preregistered Replication of the Ego-Depletion Effect to a Research Program

We reanalyze the recent multilab preregistered study on ego-depletion by Hagger and Chatzisarantis (2016 Hagger, M. S., &; Chatzisarantis, N. L. D. (2016). A multilab preregistered replication of the ego-depletion effect. Perspectives on Psychological Science, 11, 546–573. doi:10.1177/1745691616652873[Crossref], [Web of Science ®] , [Google Scholar]) as if their data were obtained under the research program-strategy (Witte &; Zenker, 2016a Witte, E. H., &; Zenker, F. (2016a). Beyond schools—Reply to Marsman, Ly, and Wagenmakers. Basic and Applied Social Psychology, 38, 313–317. doi:10.1080/01973533.2016.1227710[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], 2016b Witte, E. H., &; Zenker, F. (2016b). Reconstructing recent work on macro-social stress as a research program.

This strengthens Hagger and Chatzisarantis’s (2016 Hagger, M. S., &; Chatzisarantis, N. L. D. (2016). A multilab preregistered replication of the ego-depletion effect. Perspectives on Psychological Science, 11, 546–573. doi:10.1177/1745691616652873[Crossref], [Web of Science ®] , [Google Scholar]) main conclusion, because our reanalysis more directly corroborates the absence of a medium-sized, or a small-sized, ego-depletion effect (d?=?.50 under α?=?β?=?.05; d?=?.20 under α?=?β?=?.01). We explain how a smaller ego-depletion effect of d?=?.04 can be tested under similar conditions, having determined this value by maximum likelihood estimation, and compare the research program-strategy to a standard meta-analytic integration.     

Positive emotion impedes emotional but not cognitive conflict processing

Cognitive control enables successful goal-directed behavior by resolving a conflict between opposing action tendencies, while emotional control arises as a consequence of emotional conflict processing such as in irony. While negative emotion facilitates both cognitive and emotional conflict processing, it is unclear how emotional conflict processing is affected by positive emotion (e.g., humor). In 2 EEG experiments, we investigated the role of positive audiovisual target stimuli in cognitive and emotional conflict processing. Participants categorized either spoken vowels (cognitive task) or their emotional valence (emotional task) and ignored the visual stimulus dimension. Behaviorally, a positive target showed no influence on cognitive conflict processing, but impeded emotional conflict processing. In the emotional task, response time conflict costs were higher for positive than for neutral targets. In the EEG, we observed an interaction of emotion by congruence in the P200 and N200 ERP components in emotional but not in cognitive conflict processing. In the emotional conflict task, the P200 and N200 conflict effect was larger for emotional than neutral targets. Thus, our results show that emotion affects conflict processing differently as a function of conflict type and emotional valence. This suggests that there are conflict- and valence-specific mechanisms modulating executive control.     

Personality Predictors of Behavioral Self‐Regulation: Linking behavioral self‐regulation to five‐factor model factors,facets, and a compound trait

This study examined relationships between a composite of several facet‐level traits within the five‐factor model (FFM) of personality and outcomes across 3 phases of behavioral self‐regulation. The goal of this research was to investigate the potential of the compound trait approach as an alternative to predicting self‐regulatory outcomes based on the full FFM, conscientiousness or other FFM factor‐level traits, or any individual facet‐level trait within the FFM. These relationships were investigated using a sample of 312 participants completing both goal‐related questionnaires and a decision task designed to simulate aspects of self‐regulated performance within organizations. Consistent with hypotheses, the collection of traits within the composite – assertiveness, activity, achievement striving, deliberation, dutifulness, self‐discipline, and ideas – performed as well or better than any single factor or facet of the FFM. The future research and practice implications for goal propensity, a compound trait related to all phases of behavioral self‐regulation, are discussed.     

Verbal knowledge, working memory, and processing speed as predictors of verbal learning in older adults

The present study aimed at modeling individual differences in a verbal learning task by means of a latent structured growth curve approach based on an exponential function that yielded 3 parameters: initial recall, learning rate, and asymptotic performance. Three cognitive variables-speed of information processing, verbal knowledge, working memory-and the participant's age were included in the model in order to explain individual differences in the learning parameters. The data come from the second wave of the Zurich Longitudinal Study on Cognitive Aging (D. Zimprich, Martin, et al., 2008) comprising 334 participants ranging in age from 66 to 81 years (M = 74.43, SD = 4.41). Among the logistic, the Gompertz, and the hyperbolic function, the exponential function described the data best. Reliable individual differences were found in all 3 learning parameters. The cognitive predictor variables affected the verbal learning parameters differentially: All 3 predictors affected positively initial recall, the asymptotic performance increased with better working memory and faster processing speed, and the learning rate was positively associated with verbal knowledge only. Age did not affect the learning parameters but correlated negatively with working memory and processing speed. The finding of large and reliable individual differences in learning is seen as evidence that the potential for positive change, or plasticity in adulthood is maintained and that it is worthwhile to enhance the determinants of learning or learning itself.     

Gender characteristics of cerebral hemodynamics during complex cognitive functioning

Functional Transcranial Doppler sonography (fTCD) has been applied to assess peak mean cerebral blood flow velocity (MFV) with a high temporal resolution during cognitive activation. Yet, little attention has been devoted to gender-related alterations of MFV, including spectral analysis. In healthy subjects, fTCD was used to investigate a series of cerebral hemodynamic parameters in the middle cerebral arteries (MCA) during the Trail Making Tests (TMT), a means of selective attention and complex cognitive functioning. In females, there was a frequency peak at 0.375 Hz in both MCA, and we observed a dynamic shift in hemispheric dominance during that condition. Further, after the start phase, there was an MFV decline during complex functioning for the entire sample. These novel results suggest condition-specific features of cerebral hemodynamics in females, and it adds to the notion that gender is a fundamental confounder of brain physiology.
