The neural bases of distracter-resistant working memory

A major difference between humans and other animals is our capacity to maintain information in working memory (WM) while performing secondary tasks, which enables sustained, complex cognition. A common assumption is that the lateral prefrontal cortex (PFC) is critical for WM performance in the presence of distracters, but direct evidence is scarce. We assessed the relationship between fMRI activity and WM performance within subjects, with performance matched across distracter and no-distracter conditions. Activity in the ventrolateral PFC during WM encoding and maintenance positively predicted performance in both conditions, whereas activity in the presupplementary motor area (pre-SMA) predicted performance only under distraction. Other parts of the dorsolateral and ventrolateral PFCs predicted performance only in the no-distracter condition. These findings challenge a lateral-PFC-centered view of distracter resistance, and suggest that the lateral PFC supports a type of WM representation that is efficient for dealing with task-irrelevant input but is, nonetheless, easily disrupted by dual-task demands.     

Religious Doubt and Spiritual Growth Among Adults Bereaved of a Grandparent

Religious beliefs and bereavement provide contexts for personal growth (Benore & Park, 2004). The death of a grandparent may be especially well-suited to prompt such growth. Using data from 164 adults, ages 18 to 51 years, bereaved of a grandparent, the authors examined whether religious doubt relates to current grief via perceived spiritual growth. Mediation analyses showed that fewer religious doubts were associated with spiritual growth in bereavement, but spiritual growth was associated with higher levels of current grief. Results are discussed within a framework for including family processes in bereavement research that includes religious doubt and spiritual growth.     

Effectively Analyzing Change over Time in Laboratory Research on Stress and Health: A Multilevel Modeling Approach

Stress and health researchers often utilize standardized laboratory stress tasks to evaluate the physical and psychological consequences of challenging experiences. These laboratory sessions usually include multiple measurements of physical and psychological responses collected over time. Multilevel modeling allows researchers to make use of all available data points to model the trajectory of change over time, and within distinct task periods such as baseline, stressor, and recovery. To effectively predict future health outcomes it is important to examine both stress‐related reactivity and recovery. In this paper, we review the analytic approaches used in recent laboratory stress research and note that many recent articles have aggregated multiple responses, used difference scores, or conducted repeated measures analysis of variance (ANOVA). Relatively few studies used a multilevel modeling approach. We highlight the advantages of a multilevel modeling approach and provide an example for using this approach as an alternative to repeated measures ANOVA and difference scores.     

Memory for retinotopic locations is more accurate than memory for spatiotopic locations,even for visually guided reaching

To interact successfully with objects, we must maintain stable representations of their locations in the world. However, their images on the retina may be displaced several times per second by large, rapid eye movements. A number of studies have demonstrated that visual processing is heavily influenced by gaze-centered (retinotopic) information, including a recent finding that memory for an object’s location is more accurate and precise in gaze-centered (retinotopic) than world-centered (spatiotopic) coordinates (Golomb & Kanwisher, 2012b). This effect is somewhat surprising, given our intuition that behavior is successfully guided by spatiotopic representations. In the present experiment, we asked whether the visual system may rely on a more spatiotopic memory store depending on the mode of responding. Specifically, we tested whether reaching toward and tapping directly on an object’s location could improve memory for its spatiotopic location. Participants performed a spatial working memory task under four conditions: retinotopic vs. spatiotopic task, and computer mouse click vs. touchscreen reaching response. When participants responded by clicking with a mouse on the screen, we replicated Golomb & Kanwisher’s original results, finding that memory was more accurate in retinotopic than spatiotopic coordinates and that the accuracy of spatiotopic memory deteriorated substantially more than retinotopic memory with additional eye movements during the memory delay. Critically, we found the same pattern of results when participants responded by using their finger to reach and tap the remembered location on the monitor. These results further support the hypothesis that spatial memory is natively retinotopic; we found no evidence that engaging the motor system improves spatiotopic memory across saccades.     

Our neoliberal fantasies? A preliminary test of research trends in leading journals in work and organizational psychology

Prior to engaging in a substantive discussion on the supposed influence of neoliberalism on research in work and organizational psychology (WOP), it is important to verify the empirical basis of the trends advanced by Bal and Dóci (Neoliberal ideology in work and organizational psychology, European Journal of Work and Organizational Psychology [Online First Publication, 2018]). To this end, we content analysed 745 abstracts of empirical studies published in leading WOP journals during the years 2006–2007 and 2016–2017. Results of our content analysis do not support the hypothesized trends towards more instrumentality and individualism in WOP research, suggesting that Bal and Dóci’s (2018) portrayal of the WOP literature does not provide a solid basis for discussion. On the basis of our findings, we conclude with recommendations to broaden the scope of WOP research to also include macro-level, societal issues.
