Intelligence,Wellbeing and Procreative Beneficence

If Savulescu's (2001, 2009) controversial principle of Procreative Beneficence (PB) is correct, then an important implication is that couples should employ genetic tests for non‐disease traits in selecting which child to bring into existence. Both defenders as well as some critics of this normative entailment of PB have typically accepted the comparatively less controversial claim about non‐disease traits: that there are non‐disease traits such that testing and selecting for them would in fact contribute to bringing about the child who is expected to have the best life. We challenge this less controversial claim, not by arguing deductively for its falsity, but by showing that Savulescu's central argument for this presumably less controversial claim fails. Savulescu offers intelligence as the paradigm example of a testable non‐disease trait such that testing and selecting for it would increase the likelihood that the child selected would be the one who is expected to have the best life (or at least as good a life as the others). We provide a series of arguments aimed at demonstrating that Savulescu's argument from intelligence fails. If our arguments are successful, the upshot is not that PB is false, but more modestly, that the burden of proof remains squarely with Savulescu.     

Time-dependent forgetting in visual short-term memory

ABSTRACT

Whether visual short-term memory can be lost over an unfilled delay, in line with time-dependent forgetting, is controversial and prior work has yielded mixed results. The present study explored time-dependent forgetting in visual short-term memory in relation to other factors. In three experiments, participants compared single target and probe objects over a 2 s or 10 s retention interval. The objects across trials were either similar or dissimilar (Experiment 1) and had to be remembered in the presence of an additional distractor (Experiment 2) or under conditions where the amount of time separating trials varied (Experiment 3). In all experiments, the retention interval manipulation made the biggest contribution to performance, with accuracy decreasing as the retention interval was lengthened from 2 s to 10 s. These results pose problems for interference and temporal distinctiveness models of memory but are compatible with temporal forgetting mechanisms such as decay.     

Basic Human Values and Their Contexts: A Multilevel Analysis of Support for the Use of Armed Drones in the United States,United Kingdom,and Turkey

Armed drones are now a key component of military strategy; however, little empirical research has explored the phenomenon in terms of psychological processes. Previous research has emphasized the importance of basic human values for structuring understandings of and opinions towards foreign policy issues. Using a social representations approach, we used a multilevel modeling approach to explore the link between values and support for the use of armed drones in the United Kingdom, the United States, and Turkey. In line with our predictions, high priority of self-transcendence values negatively predicted, and high priority of conservation values positively predicted, support for armed drones. Furthermore, given our theoretical framework, we specified that values should be conceptualized as prioritized or devalued within a particular context, and when values were specified as country-level, as well as individual predictors, this led to an increase in model fit. These findings are discussed in light of a developing line of research on meta-representations and their consequences for political opinion, and directions for future research are advanced.
