Fitting an ex-Gaussian function to examine costs in event-based prospective memory: Evidence for a continuous monitoring profile

Event-based prospective memory (PM) tasks require individuals to remember to perform a deferred action when a target event occurs. PM task requirements can slow ongoing task responses on non-target trials (‘costs’) under conditions where the defining features of targets are non-focal to the ongoing task, which is indicative that individuals have allocated some form of cognitive control process to the PM task. Recent fits of the ex-Gaussian mathematical function to non-target trial response distributions by prior studies have indicated that these control processes are transiently allocated. In the current paper, fits of the ex-Gaussian function to data reported by Loft and Humphreys (2012) demonstrate a shift in the entire response time distribution (μ) and an increase in skew (τ) for a non-focal PM condition required to remember to make a PM response if presented with category exemplars, compared to a control condition. This change in μ is indicative of a more continuous PM monitoring profile than that reported by prior studies. In addition, within–subject variability in μ was reliably correlated with PM accuracy, suggesting that these control processes allocated on a regular basis were functional to PM accuracy. In contrast, when the ongoing task directed attention to the defining features of targets (focal PM) there was a trend level increase in μ, but the within–subject variability in μ was not correlated with PM accuracy, consistent with the theoretical premise that focal PM tasks are not as dependent on cognitive control as non-focal PM tasks.     

Stress in remote work: two studies testing the Demand-Control-Person model

The popularity of remote work continues to rise, but uncertainty remains about how it influences employee well-being. We extend the Demand-Control-Person (DCP) model to test both person and job factors as important considerations in remote work, suggesting that emotional stability influences the utility of autonomy as a job resource in protecting employees from strain. Additionally, we test self-determination theory (SDT), positioning need satisfaction for autonomy, relatedness, and competence as mechanisms explaining the relationship between remote work and strain. In two field studies, high–emotional stability employees reporting high levels of autonomy experienced the lowest levels of strain, with negative relationships between extent of remote work and strain. In contrast, low–emotional stability employees who also have high autonomy appear more susceptible to strain, and this may increase when they work remotely more often. Our multilevel structural equation modelling revealed that high–emotional stability employees with high autonomy appear best positioned to meet their needs for autonomy and relatedness, even when remote work is more frequent; these in turn reduced the likelihood of strain. Thus, our results support the DCP and SDT models, revealing theoretical and practical implications for designing and managing remote work arrangements.     

A Survey of Rewards for Teens: Extension and 25-Year Follow-Up

Extant reward surveys and item preferences assessments have shown to be a reliable mode of ascertaining potential reinforcers for various populations; however, many are outdated and may comprise of items or rewards that contemporary populations may not value. The purpose of this research is to extend upon the Houlihan, Jesse, Levine, and Sombke (1991 Houlihan, D., Jesse, V. C., Levine, H. D., &; Sombke, C. (1991). A survey for use with teenage children. Child &; Family Behavior Therapy, 13(1), 1–11.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) Survey of Rewards for Teens (SORT) and assess whether there is evidence of a potential, generational shift in reward preferences in high school students from 1991 to 2016. This inquiry is of particular importance to behavior analysts due to the idiosyncratic nature of reward preference, a tendency for rewards to shift over time, and the salient role played by rewards in behavior therapy programs. Results suggest that the reward preferences of contemporary high school students differ when compared to the sample of adolescents in Houlihan et al. (1991 Houlihan, D., Jesse, V. C., Levine, H. D., &; Sombke, C. (1991). A survey for use with teenage children. Child &; Family Behavior Therapy, 13(1), 1–11.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) study. In addition, a proposed revision of the SORT is provided, whose development was derived based on the resulting component structure from a principal components analysis (PCA) and inspection of component psychometric properties.

A Method of Correcting Estimation Failure in Latent Differential Equations with Comparisons to Kalman Filtering

Abstract

Studies have used the latent differential equation (LDE) model to estimate the parameters of damped oscillation in various phenomena, but it has been shown that correct, non-zero parameter estimates are only obtained when the latent series exhibits little or no process noise. Consequently, LDEs are limited to modeling deterministic processes with measurement error rather than those with random behavior in the true latent state. The reasons for these limitations are considered, and a piecewise deterministic approximation (PDA) algorithm is proposed to treat process noise outliers as functional discontinuities and obtain correct estimates of the damping parameter. Comprehensive, random-effects simulations were used to compare results with those obtained using a state-space model (SSM) based on the Kalman filter. The LDE with the PDA algorithm (LDEPDA) successfully recovered the simulated damping parameter under a variety of conditions when process noise was present in the latent state. The LDEPDA had greater precision and accuracy than the SSM when estimating parameters from data with sparse jump discontinuities, but worse performance for diffusion processes overall. All three methods were applied to a sample of postural sway data. The basic LDE estimated zero damping, while the LDEPDA and SSM estimated moderate to high damping. The SSM estimated the smallest standard errors for both frequency and damping parameter estimates.     

To Apologize or Justify: Leader Responses to Task and Relational Mistakes

Abstract

Leadership roles are complex, creating an environment where leaders are likely to make mistakes that result in negative outcomes. We shift the conversation in the literature from examining the effectiveness of mistake responses toward exploring why leaders use different mistake recovery methods. We employ an online experimental method to distinguish between task and relationship mistakes for leaders and suggest that different attributions are made for these two types of mistakes (Study 1). We found that task mistakes are viewed by leaders as more specific and less personal, and that relationship mistakes are viewed as more global, describing the leader’s stable characteristics rather than a specific event. From these findings, we predict that leaders are more likely to apologize for task mistakes and are more likely to justify their relationship mistakes rather than admit wrongdoing for them. We find support for these predictions using a mixed methods approach, employing a laboratory experiment (Study 2) and a critical incident method surveying a panel of leaders (Study 3). As such, this paper extends our understanding of the mistake recovery process for leaders by demonstrating that 1) leaders’ relationship mistakes are viewed as more globally representative of the leader than task mistakes, and 2) leaders are more likely to apologize for task mistakes but more likely to justify relationship mistakes. Relational and task mistakes, however, were not found to be different in regard to their ambiguity or the extent to which they were viewed as a mistake.
