Facing the future: Memory as an evolved system for planning future acts

All organisms capable of long-term memory are necessarily oriented toward the future. We propose that one of the most important adaptive functions of long-term episodic memory is to store information about the past in the service of planning for the personal future. Because a system should have especially efficient performance when engaged in a task that makes maximal use of its evolved machinery, we predicted that future-oriented planning would result in especially good memory relative to other memory tasks. We tested recall performance of a word list, using encoding tasks with different temporal perspectives (e.g., past, future) but a similar context. Consistent with our hypothesis, future-oriented encoding produced superior recall. We discuss these findings in light of their implications for the thesis that memory evolved to enable its possessor to anticipate and respond to future contingencies that cannot be known with certainty.     

Deep-level diversity and leadership

In the special issue on Diversity and Leadership (April 2010), the authors made a strong case for the importance of diversity in workplace leadership, rejected premature declarations that workplace discrimination is obsolete, and called for leadership theories that acknowledge and promote the value of diversity. We appreciate all authors' stressing that the glass ceiling still exists, not only for women but for other historically low-power groups as well. We also agree that modern theories of leadership can benefit immensely from increased participation by scholars and practitioners who are not Western, White, upper-class men (Chin, 2010).     

To carry or not to carry — Is this the question? Disentangling the carry effect in multi-digit addition

Recent research has suggested addition performance to be determined by both the need for a carry operation and problem size. Nevertheless, it has remained debatable, how these two factors are interrelated. In the current study, this question was pursued by orthogonally manipulating carry and problem size in two-digit addition verification. As the two factors interacted reliably, our results indicate that the carry effect is moderated by number magnitude processing rather than representing a purely procedural, asemantic sequence of processing steps. Moreover, it was found that the carry effect may not be a purely categorical effect but may be driven by continuous characteristics of the sum of the unit digits as well. Since the correct result of a carry problem can only be derived by integrating and updating the magnitudes of tens and units within the place-value structure of the Arabic number system, the present study provides evidence for the idea that decomposed processing of tens and units also transfers to mental arithmetic.     

Innovation Implementation

Abstract— In changing work environments, innovation is imperative. Yet, many teams and organizations fail to realize the expected benefits of innovations that they adopt. A key reason is not innovation failure but implementation failure—the failure to gain targeted employees' skilled, consistent, and committed use of the innovation in question. We review research on the implementation process, outlining the reasons why implementation is so challenging for many teams and organizations. We then describe the organizational characteristics that together enhance the likelihood of successful implementation, including a strong, positive climate for implementation; management support for innovation implementation; financial resource availability; and a learning orientation.     

ORDER FROM VIRTUAL STATES: A DIALOGUE ON THE RELEVANCE OF QUANTUM THEORY TO RELIGION

Abstract. Lothar Schäfer has written a poetic tribute pointing out the relevance of quantum theory to religious beliefs. Two items in his article trouble me greatly. First are the excessive claims about the relevance of quantum mechanisms for the creation and evolution of life. Schäfer's claim that “everything that can happen must happen” can be dangerously misleading. The quantum rules predict that most outcomes have a near‐zero chance of occurring. Although “anything can happen” can be a wonderful metaphor for living life, it can be dangerous if taken literally. It can also be misleading when applied to Darwinian mechanisms. My second trouble was with Schäfer's desire to extract moral values from quantum principles in a literalist manner. Extracting ethics from science has always been problematic. Luckily, Schäfer provides balance to these objections by including many wonderful passages that in my opinion correctly point out how quantum theory should change the way we conceive of our place in the universe. I list twelve points in which the quantum ontology differs from our normal Newtonian ontology. Awareness of these aspects is typically missing from our usual appreciation of nature, so Schäfer's poetry on a number of these points is well appreciated.     

Preventing preschool externalizing behavior problems through video‐feedback intervention in infancy

In the present study (1) intervention effects on children's preschool behavior problems were evaluated in a high risk sample with an overrepresentation of insecure adult attachment representations in 77 first‐time mothers, and (2) predictors and correlates of child problem behavior were examined. Early short‐term video‐feedback intervention to promote positive parenting (VIPP) focusing on maternal sensitivity and implemented in the baby's first year of life significantly protected children from developing clinical Total Problems at preschool age. Also, compared with the control group, fewer VIPP children scored in the clinical range for Externalizing Problems. No intervention effects on Internalizing clinical problem behavior were found. The VIPP effects on Externalizing and Total clinical Problems were not mediated by VIPP effects on sensitivity and infant attachment or moderated by mother or child variables. Maternal satisfaction with perceived support appeared to be associated with less children's Internalizing, Externalizing, and Total Problems. More research is needed to find the mechanisms triggered by VIPP, but the outcomes could be considered as promising first steps in the prevention of disturbing, externalizing behavior problems in young children.     

Parametric exploration of the Simon effect across visual space.

The Simon effect refers to the performance advantage for responding to the nonspatial identity of the target when the target's irrelevant location corresponds with the relative location of the response. The present study is a parametric examination of the magnitude of the Simon effect across visual space. Response keys were arranged along vertical, horizontal, and two diagonal axes, and stimuli were arranged in two concentric circles (near and far from fixation) along the same axes. The results show that the Simon effect is of similar magnitude regardless of stimulus-response axis. In contrast to findings from stimulus-response compatibility paradigms, there was no evidence in this study for the presence of an orthogonal compatibility effect or left-right prevalence effect, suggesting that these effects only arise when response location is relevant. The results demonstrate the robust generalizability of the Simon effect under different spatial conditions and thus broaden the relevance of the Simon effect to a variety of applications.     

Getting less than their fair share: Maltreated youth are hyper‐cooperative yet vulnerable to exploitation in a public goods game

Human cooperative behavior has long been thought to decline under adversity. However, studies have primarily examined perceived patterns of cooperation, with little eye to actual cooperative behavior embedded within social interaction. Game‐theoretical paradigms can help close this gap by unpacking subtle differences in how cooperation unfolds during initial encounters. This study is the first to use a child‐appropriate, virtual, public goods game to study actual cooperative behavior in 329 participants aged 9–16 years with histories of maltreatment (n = 99) and no maltreatment (n = 230) while controlling for psychiatric symptoms. Unlike work on perceived patterns of cooperation, we found that maltreated participants actually contribute more resources to a public good during peer interaction than their nonmaltreated counterparts. This effect was robust when controlling for psychiatric symptoms and peer problems as well as demographic variables. We conclude that maltreatment may engender a hyper‐cooperative strategy to minimize the odds of hostility and preserve positive interaction during initial encounters. This, however, comes at the cost of potential exploitation by others.     

Use of absolute and comparative performance feedback in absolute and comparative judgments and decisions

Which matters more—beliefs about absolute ability or ability relative to others? This study set out to compare the effects of such beliefs on satisfaction with performance, self-evaluations, and bets on future performance. In Experiment 1, undergraduate participants were told they had answered 20% correct, 80% correct, or were not given their scores on a practice test. Orthogonal to this manipulation, participants learned that their performance placed them in the 23rd percentile or 77th percentile, or they did not receive comparative feedback. Participants were then given a chance to place bets on two games—one in which they needed to get more than 50% right to double their money (absolute bet), and one in which they needed to beat more than 50% of other test-takers (comparative bet). Absolute feedback influenced comparative betting, particularly when no comparative feedback was available. Comparative feedback exerted weaker and inconsistent effects on absolute bets. Absolute feedback also had stronger (and more consistent) effects on satisfaction with performance and state self-esteem. Experiment 2 replicated these effects in a different university sample, and demonstrated that the effects emerge even when bets are placed after participants rate their satisfaction with their performance (although these ratings do not mediate the effect of feedback on bets). These findings suggest that information about one’s absolute standing on a dimension may be more influential than information about comparative standing, partially supporting a key tenet of Festinger’s [Festinger, L. (1954). A theory of social comparison processes. Human Relations, 7, 117–140.] theory of social comparison.
