The ontogeny of relational memory and pattern separation

Episodic memory relies on memory for the relations among multiple elements of an event and the ability to discriminate among similar elements of episodes. The latter phenomenon, termed pattern separation, has been studied mainly in young and older adults with relatively little research on children. Building on prior work with young children, we created an engaging computer‐administered relational memory task assessing what‐where relations. We also modified the Mnemonic Similarity Task used to assess pattern discrimination in young and older adults for use with preschool children. Results showed that 4‐year‐olds performed significantly worse than 6‐year‐olds and adults on both tasks, whereas 6‐year‐olds and adults performed comparably, even though there were no ceiling effects. However, performance on the two tasks did not correlate, suggesting that two distinct mnemonic processes with different developmental trajectories may contribute to age‐related changes in episodic memory.     

Individual differences in white matter microstructure predict semantic control

In everyday conversation, we make many rapid choices between competing concepts and words in order to convey our intent. This process is termed semantic control, and it is thought to rely on information transmission between a distributed semantic store in the temporal lobes and a more discrete region, optimized for retrieval and selection, in the left inferior frontal gyrus. Here, we used diffusion tensor imaging in a group of neurologically normal young adults to investigate the relationship between semantic control and white matter tracts that have been implicated in semantic memory retrieval. Participants completed a verb generation task that taps semantic control (Snyder & Munakata, 2008; Snyder et al., 2010) and underwent a diffusion imaging scan. Deterministic tractography was performed to compute indices representing the microstructural properties of the inferior fronto-occipital fasciculus (IFOF), the uncinate fasciculus (UF), and the inferior longitudinal fasciculus (ILF). Microstructural measures of the UF failed to predict semantic control performance. However, there was a significant relationship between microstructure of the left IFOF and ILF and individual differences in semantic control. Our findings support the view put forth by Duffau (2013) that the IFOF is a key structural pathway in semantic retrieval.     

Commission errors but not critical lures decrease when you have to pay a price for them

Using the Deese-Roediger-McDermott paradigm, we explored the effect of monetary penalty on false memories. Participants were presented 6 15-word lists of semantic associates that all converged on a nonpresented critical lure. Next, half of the participants received a monetary reward (0.10 Euro; about $0.10) for each correctly recalled word, whereas they lost money (0.20 Euro; about $0.20) for each incorrect response. Compared with control participants who received a fixed financial compensation, participants in the experimental group reported fewer commissions (i.e., incorrect responses other than the critical lure). Number of hits and critical lures did not differ between the groups.     

Payoffs for layoffs? An examination of CEO relative pay and firm performance surrounding layoff announcements

In this study, we theorize that chief executive officers’ (CEOs’) peer pay comparisons influence their decisions to engage in layoffs, and we consider the conditions under which layoffs deliver “payoffs” in the form of increases in subsequent CEO relative pay. Our results indicate that CEOs receiving compensation below their peers are significantly more likely to announce layoffs in the subsequent year, relative to those receiving compensation above their peers. Further, we find that the relationship between layoffs and subsequent changes in CEO relative pay depends on postlayoff changes in firm performance, with CEOs in firms with the largest performance gains receiving the largest increases in relative pay. We also show that our results are robust to an alternative operationalization of CEO relative pay. We provide evidence that external social comparisons may have predictable consequences for both CEOs’ propensities to engage in particular strategic actions and future changes in CEOs’ relative pay.     

Work Stress and Comfort in University Faculty: Do Gender and Academic Field Matter?

University faculty face stressors, including multiple roles, institutional pressures, and varying student demands, which may differ by gender and across fields. Using the questionnaire variant of a convergent mixed-methods design, we examined whether self-reported work stress and comfort differed by gender and academic field gender stereotype in participants from two universities. Results showed that female faculty reported more quantitative role overload, qualitative role overload, and career development stress than male faculty regardless of field. Qualitative themes centered on institutional barriers and unique pressures for women, although these experiences varied by field. Implications, limitations, and future research for employment counselors are explored.     

Ethical Leadership and Unethical Pro-Organisational Behaviour: The Mediating Mechanism of Reflective Moral Attentiveness

This study examines the mediating effects of reflective moral attentiveness on the relationship between ethical leadership and subordinates’ unethical pro-organisational behaviour (UPB). Based on two-wave survey data obtained from 233 employees in 60 teams from Chinese government agencies, we found that ethical leadership was positively related to reflective moral attentiveness. In addition, we found that reflective moral attentiveness mediated the relationship between ethical leadership and UPB, such that ethical leadership negatively influenced subordinates’ unethical pro-organisational behaviour through enhancing reflective moral attentiveness.     

Art as Festival in Heidegger and Gadamer

In 'Art as Festival', I put Heidegger and Gadamer into dialogue concerning their respective critiques of traditional aesthetics and their more positive views on the work of art. I use the festival theme to examine some of the philosophical issues in Heidegger's and Gadamer's approaches to the work of art. Specifically, I look at the way both figures conceive the work of art as an encounter which, like the festival, involves a transcendence of subjectivity in an encounter with an event - in this case, the artwork - which the individual does not direct, but rather in which they participate. Putting the theme of festival into play also provides a useful critical lever, especially in the way that it raises important issues of community. More specifically, reflecting on the festival celebration raises questions of the nature of this community, of the relation of the community created in the festival event to the community of the everyday, and thus also of the relation of the aesthetic and the political.     

More Bang for the Buck?: Personality Traits as Moderators of Responsiveness to Pay-for-Performance

Extensive prior research has found that, on average, people are more productive under properly designed incentive pay systems; this effect is not necessarily uniform across people, however. In two laboratory studies utilizing within-person study designs and tasks varying in level of structure, we examine how individuals’ personality dispositions systematically predict differential responsiveness to pay-for-performance (PFP) relative to fixed pay. As expected, average productivity was higher when people received PFP (in the form of piecework pay) than when they received fixed pay, but the productivity-enhancing effects of PFP were especially pronounced for more extraverted and less conscientious individuals in less structured tasks. Emotionally stable individuals also had enhanced productivity under PFP, an effect that has not been observed in previous research on personality and pay.
