Cumulative Advantage: Conductors and Insulators of Heavy‐Tailed Productivity Distributions and Productivity Stars

We use the metatheoretical principle of cumulative advantage as a framework to understand the presence of heavy‐tailed productivity distributions and productivity stars. We relied on 229 datasets including 633,876 productivity observations collected from approximately 625,000 individuals in occupations including research, entertainment, politics, sports, sales, and manufacturing, among others. We implemented a novel methodological approach developed in the field of physics to assess the precise shape of the productivity distribution rather than relying on a normal versus nonnormal artificial dichotomy. Results indicate that higher levels of multiplicity of productivity, monopolistic productivity, job autonomy, and job complexity (i.e., conductors of cumulative advantage) are associated with a higher probability of an underlying power law distribution, whereas lower productivity ceilings (i.e., insulator of cumulative advantage) are associated with a lower probability. In addition, higher levels of multiplicity of productivity, monopolistic productivity, and job autonomy were associated with a greater proportion of productivity stars (i.e., productivity distributions with heavier tails), whereas lower productivity ceilings were associated with a smaller proportion of productivity stars (i.e., productivity distributions with lighter tails). Results serve as a building block for future theory development and testing efforts aimed at understanding why, when, and how the distribution of individual productivity may follow a nonnormal curve—and to what extent. We also discuss implications for organizations and management in terms of the design and implementation of human resource systems (e.g., selection, training, compensation), as well as for individuals interested in becoming productivity stars themselves.     

Route learning in Korsakoff's syndrome: Residual acquisition of spatial memory despite profound amnesia

Korsakoff's syndrome (KS) is characterized by explicit amnesia, but relatively spared implicit memory. The aim of this study was to assess to what extent KS patients can acquire spatial information while performing a spatial navigation task. Furthermore, we examined whether residual spatial acquisition in KS was based on automatic or effortful coding processes. Therefore, 20 KS patients and 20 matched healthy controls performed six tasks on spatial navigation after they navigated through a residential area. Ten participants per group were instructed to pay close attention (intentional condition), while 10 received mock instructions (incidental condition). KS patients showed hampered performance on a majority of tasks, yet their performance was superior to chance level on a route time and distance estimation tasks, a map drawing task and a route walking task. Performance was relatively spared on the route distance estimation task, but there were large variations between participants. Acquisition in KS was automatic rather than effortful, since no significant differences were obtained between the intentional and incidental condition on any task, whereas for the healthy controls, the intention to learn was beneficial for the map drawing task and the route walking task. The results of this study suggest that KS patients are still able to acquire spatial information during navigation on multiple domains despite the presence of the explicit amnesia. Residual acquisition is most likely based on automatic coding processes.     

Negative mood disrupts self- and reward-biases in perceptual matching

There are established effects of self- and reward-biases even on simple perceptual matching tasks [Sui, J., He, X., &; Humphreys, G. W. (2012). Perceptual effects of social salience: Evidence from self-prioritization effects on perceptual matching. Journal of Experimental Psychology, Human Perception and Performance, 38, 1105–1117]; however we know little about whether these biases can be modulated by particular interventions, and whether the biases then change in the same way. Here we assessed how the biases alter under conditions designed to induce negative mood. We had participants read a list of self-related negative or neutral mood statements [Velten, E. (1968). A laboratory task for induction of mood states. Behavior Research and Therapy, 6, 473–482] and also listen for 10?min to a passage of negative or neutral music, prior to carrying out perceptual matching with shapes associated to personal labels (self or stranger) or reward (£12 or £1). Responses to the self- and high-reward-associated shapes were selectively slower and less sensitive (d′) following the negative mood induction procedures, and the decrease in mood correlated with decreases in the reaction time bias across “high saliency” (self and high-reward) stimuli. We suggest that negative mood may decrease self- and reward-biases through reducing attention to salient external stimuli.

Meeting in the House of Callias: Rhetoric and Dialectic

The purpose of this paper is to briefly describe and compare the original goals and perspectives of both rhetoric and dialectic in theory and in practice. Dialectic is the practice and theory of conversations; rhetoric that of speeches. For theory of dialectic, this paper will turn to Aristotle's Topics and Sophistical Refutations; for theory of rhetoric, to his Rhetoric. Thus it will appear that rhetoric and dialectic are pretty close. Yet, on the other hand, there is a long tradition of mutual antagonism. The paper tries to summarize the common features of, as well as the differences between, the two. To get a taste of both dialectic and rhetoric in practice the reader is invited to enter the House of Callias, as we know it from Plato's Protagoras. After this visit there remains no doubt that rhetoric and dialectic are intertwined on the level of practice. Moreover, we may look forward to their integration on the level of theory.     

Identity processing style and cognitive attributional strategies: similarities and difference across different contexts

Identity processing style refers to the manner in which individuals approach or manage to avoid identity relevant problems and decisions. Two studies were designed to investigate the relationship between identity style and the specific cognitive and attributional strategies youth deploy in achievement and affiliative contexts. In Study 1, 198 American late adolescents filled in the revised Identity Style Inventory and a Strategy and Attribution Questionnaire. In Study 2, 109 Finnish late adolescents filled in the same measures. Study 1 revealed that diffuse/avoidant‐oriented American youth relied on maladaptive strategies in both contexts. Information‐oriented youth engaged in more strategic planning than did their normative and diffuse/avoidant counterparts. Study 2 indicated an identical pattern of associations among the identity processing styles and cognitive and attributional strategies for Finnish youth in achievement but not in interpersonal settings. The results are discussed in the context of a social–cognitive theory of identity development. Copyright © 1999 John Wiley & Sons, Ltd.     

Sex differences in personality are larger in gender equal countries: Replicating and extending a surprising finding

Sex differences in personality have been shown to be larger in more gender equal countries. We advance this research by using an extensive personality measure, the IPIP‐NEO‐120, with large country samples (N > 1000), from 22 countries. Furthermore, to capture the multidimensionality of personality we measure sex differences with a multivariate effect size (Mahalanobis distance D). Results indicate that past research, using univariate measures of effect size, have underestimated the size of between‐country sex differences in personality. Confirming past research, there was a strong correlation (r = .69) between a country's sex differences in personality and their Gender Equality Index. Additional analyses showed that women typically score higher than men on all five trait factors (Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness), and that these relative differences are larger in more gender equal countries. We speculate that as gender equality increases both men and women gravitate towards their traditional gender roles.     

Comments on the 2018 IAAP Conference on Archetype Theory: defending a non‐reductive biological approach

During the course of the 2018 IAAP conference, a criticism of Jung’s idea of the archetype as inherited predisposition was raised that involved examining a number of dreams and visions and assessing them through developments in genetics and neuroscience. From this comparison it was argued that archetypes cannot be inherited and could more reasonably be argued to derive from early experiences. In this essay, the author responds by showing how this conclusion is flawed due to being based on reductive errors. An alternative, non‐reductive but inherited and biological position on the archetype is defended.
