Abstract

An automated wireless system (WS) for sleep monitoring was recently developed and validated for assessing nighttime sleep. Here, we aimed to evaluate the validity of the WS to correctly monitor daytime sleep during naps compared to polysomnography (PSG). We found that the WS underestimated wake, sleep onset latency, and wake after sleep onset. Meanwhile, it overestimated total sleep time, sleep efficiency, and duration of REM sleep. Sensitivity was moderate for wake (58.51%) and light sleep (66.92%) and strong for deep sleep (83.46%) and REM sleep (82.12%). These results demonstrated that the WS had a low ability to detect wake and systematically overscored REM sleep, implicating the WS as an inadequate substitute for PSG in diagnosing sleep disorders or for research in which sleep staging is essential.

5. Examining the Influence of Perceived Stress on Developmental Change in Memory and Perceptual Speed for Adopted and Nonadopted Individuals

Author

Ricker, Ashley A., Corley, Robin, DeFries, John C., Wadsworth, Sally J., and Reynolds, Chandra A.

Abstract

The present study prospectively evaluated cumulative early life perceived stress in relation to differential change in memory and perceptual speed from middle childhood to early adulthood. We aimed to identify periods of cognitive development susceptible to the effects of perceived stress among both adopted and nonadopted individuals. The sample consisted of participants in the Colorado Adoption Project (CAP, N = 690). Structured latent growth curves were fit to 4 memory outcomes as well as 1 perceptual speed outcome, which described nonlinear change between ages 9 and 30. Both adoption status and cumulative perceived stress indices served as predictors of the latent curves. The perceived stress indices were constructed from the Brooks-Gunn Life Events Scale for Adolescents, and reflected "upsettingness" ratings associated with the occurrence of particular life events during middle childhood (ages 9 to 12) and adolescence (ages 13 to 16). For memory and perceptual speed, cumulative perceived stress did not predict differential cognitive gains. However, differences in perceptual speed trajectories between nonadopted and adopted individuals were observed, with adopted individuals showing smaller gains. Although these findings provide no evidence that emergent variability in memory and perceptual speed trajectories by age 30 are explained by cumulative perceptions of stress in childhood and adolescence, further investigations regarding potential vulnerability across the life span are warranted.

Abstract

Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available.

11. Influence of Interactive Media on Episodic Memory Development During Middle Childhood

Abstract

This dissertation evaluates the influence of exposure to interactive media and tablet-based gaming on metacognition and episodic memory development during middle childhood. Despite a growing body of literature demonstrating the impacts of exposure to interactive media on various aspects of cognitive development, the effects on episodic memory have been largely unexplored. This dissertation addresses this dearth by presenting a conceptual model that describes metacognition as mediating the effects of interactive media on episodic memory in middle childhood. This model allows for the production of multiple testable hypotheses and guides the four overarching research questions addressed in the dissertation. These research questions were investigated using multiple data sets, an experimental intervention, and a variety of statistical approaches across three manuscripts presented as chapters. Findings suggest that the effects of interactive media are not uniform, but rather vary as a function of the child’s age. That is, children’s episodic memory encoding skills are more susceptible to the influence of interactive gaming in middle childhood rather than early childhood, once metacognitive skills have come online. The impacts of interactive media also vary based on features of interactive devices or games and the environments they provide for children. Games high in adaptivity, control, and feedback provided children with more opportunities for metacognitive experiences. After a two-week intervention, manipulating the types of gaming environments children experience in the home, small but significant improvements in episodic memory encoding was observed. This dissertation makes both theoretical and applied contributions to the field of cognitive development. Importantly, these findings provide insight into the mechanisms through which episodic memory is influenced by exposure to different types of interactive media. Additionally, they highlight the importance of considering specific features of interactive games or devices (e.g., adaptivity, control, and feedback) and the types of environments they provide for children in the design of future interactive media targeted at promoting learning environments. Finally, this dissertation provides readily translatable evidence-based research to a wide audience of consumers and policy makers regarding how exposure to different types of interactive media might enhance or inhibit children’s metacognition and episodic memory development.

Abstract

Gilbert et al. conclude that evidence from the Open Science Collaboration's Reproducibility Project: Psychology indicates high reproducibility, given the study methodology. Their very optimistic assessment is limited by statistical misconceptions and by causal inferences from selectively interpreted, correlational data. Using the Reproducibility Project: Psychology data, both optimistic and pessimistic conclusions about reproducibility are possible, and neither are yet warranted.

Abstract

Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

Abstract

Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.
