When Your Race Is Almost Run,but You Feel You're Not Yet Done: Application of the Propulsion Theory of Creative Contributions to Late‐career Challenges

The propulsion theory of creative contributions is a theory that focuses on how a creative act or product builds on and adds to knowledge in various fields. In this article, we apply the propulsion theory of creative contributions not to creative discoveries or inventions, but rather to late‐career decisions about future directions in which one can steer one's career. We consider eight different kinds of career decisions one can make—replication, redefinition, forward incrementation, advance forward incrementation, redirection, reconstruction/redirection, reinitiation, and synthesis. Each offers a viable option for closing out a creative career.     

The Universal Principles of Evolution

Here we identify the core properties of genetic evolution with the intention of providing a unified definition of evolving systems that applies unequivocally in the natural and social sciences. Our definition is: evolution sustains organized systems through high fidelity replication of information. This definition can be broken down into five essential components: (1) high fidelity replication of information with 0% < survival rate < 100%; (2) expendable replication technology distinct from the replication information; (3) inert information that provides no kinetic energy to the replication process; (4) demonstrates a quantifiable resistance to entropy; (5) demonstrates intentionality.     

Self-Prophecy Effects and Voter Turnout: An Experimental Replication

Psychological research has found that being asked to predict one's future actions can bring about subsequent behavior consistent with the prediction but different from what would have occurred had no prediction been made. In a 1987 study, Greenwald, Carnot, Beach, and Young induced an increase in voting behavior by means of such a "self-prophecy" effect: Undergraduates who were asked to predict whether they would vote in an upcoming election were substantially more likely to go to the polls than those who had not been asked for a prediction. This paper reports on a replication of the Greenwald study conducted among a larger group of respondents more representative of the American electorate. No evidence was found that self-prophecy effects increase voter turnout.     

A National Survey on Multicultural Competence for Professional Counselors: A Replication Study

The purpose of this investigation was to replicate findings from Holcomb‐McCoy and Myers's ( 1999 ) study, which assessed the multicultural competence of professional counselors. Factor analysis was conducted to determine the components of multicultural competence (N = 171). Differences existed between multicultural competence and race/ethnicity, F(2, 168) = 4.86, p = .009, Wilks's Λ = .95, partial η² = .06, and education level, F(2, 167) = 8.95, p < .001, Wilks's Λ = .82, partial η² = .10.     

Quantifying the three-dimensional joint position sense of the shoulder

Joint position sense is important for performing activities of daily living and recreational activities. The objective of this study was to develop new insights into the proprioceptive capabilities of the shoulder using a novel virtual reality paradigm where participants actively recreated shoulder positions in all three dimensions. This allows for better identification of changes in joint position sense across different shoulder postures. Ten males and ten female healthy adults matched a cursor controlled by shoulder rotations calculated from motion capture tracking, to a target shoulder position presented in a virtual environment with the use of a virtual reality headset. Four elevation angles, three plane of elevation angles, and three rotation angles were investigated, totaling thirty-six angles that encompassed the range of motion of the shoulder. Joint position sense was enhanced as the elevation angle was increased, and further enhanced when the arm was more externally rotated and elevated. As elevation angle increased to 90°, joint position sense significantly increased. There was also a significant interaction of external rotation on elevation angle. As elevation angle increased, participants were more accurate when the arm was externally, but exhibited greater variability. These improvements in joint position sense are likely produced by increased tension in muscles and capsuloligamentous mechanoreceptors within the shoulder. As many sports and activities of daily living require joint position sense to complete a task, the ability to elevate and externally rotate is important for adequate shoulder proprioception and control.     

No experimental evidence for emotion-specific gaze cueing in a threat context

We examined the utility of a gaze cueing paradigm to examine sensitivity to differences among negatively valenced expressions. Participants judged target stimuli (dangerous or safe), the location of which was cued by the gaze direction of a central face. Dawel et al. reported that gaze cueing effects (faster response times on valid vs. invalid trials) were larger when the central face displayed fear than when it displayed happiness. Our aim was to determine whether this effect was specific to fear, to all threat-related expressions (fear, anger), or to all negatively valenced expressions (fear, anger, sadness, disgust) with the aim of using this protocol to study the development of implicit discrimination of negatively valenced expressions. Across five experiments in which we varied the number of models (1 vs. 4), the number of expressions (2 vs. 5), and the country of residence of participants (Canada vs. Australia) we found no evidence that the magnitude of gaze cueing effects is modulated by expression. We discuss our failure to replicate in the context of the broader literature.     

The impact of past behaviour normality on regret: replication and extension of three experiments of the exceptionality effect

Norm theory (Kahneman, D., & Miller, D. T. (1986). Norm theory: Comparing reality to its alternatives. Psychological Review, 93, 136–153) described a tendency for people to associate stronger regret with a negative outcome when it is a result of an exception (abnormal behaviour) compared to when it is a result of routine (normal behaviour). In two pre-registered studies, we conducted a replication and extension of three classic experiments on past behaviour exception/routine contrasts (N?=?684). We successfully replicated Kahneman and Miller’s (1986) experiments with the classic hitchhiker-scenario (Part 1) and car accident-scenario (Part 2). In both cases, participants examined negative outcomes and tended to indicate a protagonist who deviated from own past behaviour as more regretful than another who followed routine. Pre-registered extensions also showed effects for ratings of social norms, negative affect, and perceived luck. We did not find support for the Miller, D. T., and McFarland, C. [(1986). Counterfactual thinking and victim compensation: A test of norm theory. Personality and Social Psychology Bulletin, 12, 513–519] experiment robbery scenario (Part 3) using a compensation measure, in that compensation to a victim of a robbery was not significantly different comparing exceptional and routine circumstances. However, a pre-registered extension showed that robbery under exceptional circumstances was perceived as more regretful than robbery under routine circumstances. We discuss implications for current and future research.     

Reinventing ourselves

In my role as President of the European Association of Work and Organizational Psychology, I provide an introduction to the ‘Manifesto for the Future of Work and Organizational Psychology’ (this issue), positioning the manifesto within our association’s and discipline’s broader focus on renewal and improvement.     

A note on Type S/M errors in hypothesis testing

Motivated by the recent replication and reproducibility crisis, Gelman and Carlin (2014, Perspect. Psychol. Sci., 9, 641) advocated focusing on controlling for Type S/M errors, instead of the classic Type I/II errors, when conducting hypothesis testing. In this paper, we aim to fill several theoretical gaps in the methodology proposed by Gelman and Carlin (2014, Perspect. Psychol. Sci., 9, 641). In particular, we derive the closed-form expression for the expected Type M error, and study the mathematical properties of the probability of Type S error as well as the expected Type M error, such as monotonicity. We demonstrate the advantages of our results through numerical and empirical examples.     

Lessons worth repeating: Sidman's Tactics of Scientific Research

Murray Sidman's (1960) Tactics of Scientific Research: Evaluating Experimental Data in Psychology just celebrated its sixtieth anniversary. It is without doubt one of the most influential books in the history of Behavior Analysis. This review outlines the rationales for, and details of, methods for the investigation of the behavior of individual subjects that Sidman presented. Many of his observations and recommendations are as timely as ever, maybe even more so, given the “reproducibility crisis” and one of its major origins.
