Maternal prenatal depressive symptoms (PD symptoms) pose a risk factor for child adjustment difficulties (CAD), defined as internalizing and externalizing symptoms. This study examined the underlying mechanisms of the link between PD symptoms and CAD in a longitudinal study. Longitudinal data from pregnancy to age 3, encompassing four assessment points, were analyzed for = 582 mothers participating in the German family panel .

Response speeds in simple decision-making tasks begin to decline from early and middle adulthood. However, response times are not pure measures of mental speed but instead represent the sum of multiple processes. Here we apply a Bayesian diffusion model to extract interpretable cognitive components from raw response time data.

In recent years, mathematical models of decision making, such as the diffusion model, have been endorsed in individual differences research. These models can disentangle different components of the decision process, like processing speed, speed-accuracy trade-offs, and duration of non-decisional processes. The diffusion model estimates individual parameters of cognitive process components, thus allowing the study of individual differences.

In comparison to young adults, middle-aged and old people show lower scores in intelligence tests and slower response times in elementary cognitive tasks. Whether these well-documented findings can both be attributed to a general cognitive slow-down across the life-span has become subject to debate in the last years. The drift diffusion model can disentangle three main process components of binary decisions, namely the speed of information processing, the conservatism of the decision criterion and the non-decision time (i.

Older adults typically show slower response times in basic cognitive tasks than younger adults. A diffusion model analysis allows the clarification of why older adults react more slowly by estimating parameters that map distinct cognitive components of decision making. The main components of the diffusion model are the speed of information uptake (drift rate), the degree of conservatism regarding the decision criterion (boundary separation), and the time taken up by non-decisional processes (i.

Several previous studies reported relationships between speed of information processing as measured with the drift parameter of the diffusion model (Ratcliff, 1978) and general intelligence. Most of these studies utilized only few tasks and none of them used more complex tasks. In contrast, our study ( = 125) was based on a large battery of 18 different response time tasks that varied both in content (numeric, figural, and verbal) and complexity (fast tasks with mean RTs of ca.

Empirical findings demonstrate gender differences in attitudes toward meat consumption and actual meat-eating behavior. Furthermore, several studies have found that men score higher on all three Dark Triad personality dimensions (Machiavellianism, narcissism, and psychopathy). In this study, we investigated whether these personality differences mediate the association between gender and meat-eating justification, which in turn was expected to predict meat consumption.
