FERTILITY DIFFERENTIALS AMONG SERBIAN JEWS

Recent studies tend to validate the important role played by culture and especially religion in fertility behaviours. This paper investigates a link between religiosity and fertility among Serbian Jewish populations, namely the Sephardi and Ashkenazi Jews. It is found that among Serbian Jews, in spite of general low levels of fertility, religiousness (measured by time devoted to religious activities) and ethnic origin contribute to the fertility differentials. This paper sets out to explore the relationship between religiosity and fertility among Jews in Serbia and whether religiosity has contributed to the fertility differential between the main branches of the Serbian Jewry, namely the Sephardim and Ashkenazim.     

Task switches under Go/NoGo conditions and the decomposition of switch costs

Alternating switches between two simple S-R tasks are combined with Go/NoGo tasks. Non-switches after Go trials are assumed to selectively profit from stimulus driven repetition benefits, whereas switches after NoGo trials are assumed to be selectively delayed by stimulus driven negative priming. Intentionally driven reconfiguration costs are assessed by RT differences between switches after Go trials (no negative priming) and non-switches after NoGo trials (no repetition benefits). Experiment 1 indicates that with short preparation time repetition benefits, negative priming costs, and intentional components contribute approximately additively to switch costs. Experiment 2 confirms that the delay of switches after NoGo trials is indeed due to negative priming. Experiments 3 and 4 show that repetition benefits and intentional components of switch costs are properly assessed only if the settings assure that participants reconfigure the required task set in NoGo as well as Go trials.

Self‐paced study time as a cue for recall predictions across school age

Recent work on metacognition indicates that monitoring is sometimes based itself on the feedback from control operations. Evidence for this pattern has not only been shown in adults but also in elementary schoolchildren. To explore whether this finding can be generalized to a wide range of age groups, 160 participants from first to eighth grade participated in a study based on a self‐paced study time (ST) allocation paradigm. In contrast to previous studies, picture pairs instead of word pairs were used as stimuli to compensate for reduced reading skills in younger participants. Actual ST and judgments of learning (JOLs) made at the end of each study trial were used as core variables. The results are in line with previous findings, in that children's JOLs decreased with increasing ST, suggesting that JOLs were based on the memorizing effort heuristic that easily learned items are more likely to be remembered. Weaker inverse relationship between JOLs and ST was found for the younger children. Overall, these results underline the importance of mnemonic cues in shaping metacognitive feelings not only in adults but also in older children and expose a developmental trend in their use along childhood.     

Computer-based Testing and Training with Scenarios from Complex Problem-solving Research: Advantages and Disadvantages

The use of PC-based simulations for selection and training for jobs which require complex problem solving skills is ever-increasing. This paper gives a short review of such simulations along with a list of advantages and disadvantages of their use. Possible future developments are sketched.
