Cognitive Abilities in the Wild: Population-scale game-based cognitive assessment
Psychology and the social sciences are undergoing a revolution: It has become
increasingly clear that traditional lab-based experiments fail to capture the
full range of differences in cognitive abilities and behaviours across the
general population. Some progress has been made toward devising measures that
can be applied at scale across individuals and populations. What has been
missing is a broad battery of validated tasks that can be easily deployed, used
across different age ranges and social backgrounds, and employed in practical,
clinical, and research contexts. Here, we present Skill Lab, a game-based
approach allowing the efficient assessment of a suite of cognitive abilities.
Skill Lab has been validated outside the lab in a crowdsourced population-size
sample recruited in collaboration with the Danish Broadcast Company (Danmarks
Radio, DR). Our game-based measures are five times faster to complete than the
equivalent traditional measures and replicate previous findings on the decline
of cognitive abilities with age in a large population sample. Furthermore, by
combining the game data with an in-game survey, we demonstrate that this unique
dataset has implication for key questions in social science, challenging the
Jack-of-all-Trades theory of entrepreneurship and provide evidence for risk
preference being independent of executive functioning.Comment: 11 pages, 4 figures, and 2 table
Unveiling Mycoplasma hyopneumoniae Promoters: Sequence Definition and Genomic Distribution
Several Mycoplasma species have had their genome completely sequenced, including four strains of the swine pathogen Mycoplasma hyopneumoniae. Nevertheless, little is known about the nucleotide sequences that control transcriptional initiation in these microorganisms. Therefore, with the objective of investigating the promoter sequences of M. hyopneumoniae, 23 transcriptional start sites (TSSs) of distinct genes were mapped. A pattern that resembles the σ70 promoter −10 element was found upstream of the TSSs. However, no −35 element was distinguished. Instead, an AT-rich periodic signal was identified. About half of the experimentally defined promoters contained the motif 5′-TRTGn-3′, which was identical to the −16 element usually found in Gram-positive bacteria. The defined promoters were utilized to build position-specific scoring matrices in order to scan putative promoters upstream of all coding sequences (CDSs) in the M. hyopneumoniae genome. Two hundred and one signals were found associated with 169 CDSs. Most of these sequences were located within 100 nucleotides of the start codons. This study has shown that the number of promoter-like sequences in the M. hyopneumoniae genome is more frequent than expected by chance, indicating that most of the sequences detected are probably biologically functional
