Attentional priming: recent insights and current controversies.

Curr Opin Psychol 2018 Nov 28;29:71-75. Epub 2018 Nov 28.

Icelandic Vision Laboratory, School of Humanitites and Social Sciences, University of Akureyri. Hafnarstræti 97, Akureyri IS600, Iceland.

Humans possess a primitive memory system for attention deployments that allows quick reorientation of visual attention to stimuli that are relevant to behavior at any given moment. We review recent evidence regarding such attentional priming effects from a number of different perspectives. We discuss recent findings on the time course and duration of such effects, the potential interaction of priming and top-down attentional guidance; how priming can be used to probe the nature of visual representations and attentional templates; findings on the basic nature of priming effects and recent relevant findings on so-called serial dependencies that share many characteristics with attentional priming.

Alternative splicing of the vitamin D receptor modulates target gene expression and promotes ligand-independent functions.

Toxicol Appl Pharmacol 2018 Dec 12. Epub 2018 Dec 12.

Department of Environmental and Molecular Toxicology, Oregon State University, 1007 Agriculture & Life Sciences Building, Corvallis, OR 97331; USA; LS Pharma, 884 Park St., Lebanon, OR 97355; USA.

Alternative splicing modulates gene function by creating splice variants with alternate functions or non-coding RNA activity. Naturally occurring variants of nuclear receptor (NR) genes with dominant negative or gain-of-function phenotypes have been documented, but their cellular roles, regulation, and responsiveness to environmental stress or disease remain unevaluated. Informed by observations that class I androgen and estrogen receptor variants display ligand-independent signaling in human cancer tissues, we questioned whether the function of class II NRs, like the vitamin D receptor (VDR), would also respond to alternative splicing regulation.

The influence of the OPRM1 (A118G) polymorphism on behavioral and neural correlates of aggression in healthy males.

Neuropharmacology 2018 Dec 12. Epub 2018 Dec 12.

Department of Psychiatry, Psychotherapy and Psychosomatics, Faculty of Medicine, RWTH Aachen University, 52074, Aachen, Germany; JARA Institute Brain Structure Function Relationship Institute for Neuroscience and Medicine (INM 10), Forschungszentrum Jülich, 52425 Jülich, Germany.

Current models of aggression suggest that in addition to personality traits and environmental factors, biological vulnerability associated with genetics substantially impacts aggressive behavior. In a functional imaging study, we investigated the influence of the single nucleotide polymorphism of the mu 1 subtype opioid receptor gene (OPRM1), implicated in sociability, on correlates of trait and state aggression to delineate the function of these influences in aggression. A key aim was further to differentiate different aspects of aggressive reactions - namely, the reaction to provocation and the decision to punish an opponent. Read More

Cell-Based Model of the Generation and Maintenance of the Shape and Structure of the Multilayered Shoot Apical Meristem of Arabidopsis thaliana.

Bull Math Biol 2018 Dec 14. Epub 2018 Dec 14.

Department of Mathematics, University of California, Riverside, USA.

One of the central problems in animal and plant developmental biology is deciphering how chemical and mechanical signals interact within a tissue to produce organs of defined size, shape, and function. Cell walls in plants impose a unique constraint on cell expansion since cells are under turgor pressure and do not move relative to one another. Cell wall extensibility and constantly changing distribution of stress on the wall are mechanical properties that vary between individual cells and contribute to rates of expansion and orientation of cell division.

Foraging Performance, Prosociality, and Kin Presence Do Not Predict Lifetime Reproductive Success in Batek Hunter-Gatherers.

Hum Nat 2018 Dec 14. Epub 2018 Dec 14.

Department of Anthropology, Dartmouth College, Hanover, NH, 03755, USA.

Identifying the determinants of reproductive success in small-scale societies is critical for understanding how natural selection has shaped human evolution and behavior. The available evidence suggests that status-accruing behaviors such as hunting and prosociality are pathways to reproductive success, but social egalitarianism may diminish this pathway. Here we introduce a mixed longitudinal/cross-sectional dataset based on 45 years of research with the Batek, a population of egalitarian rain forest hunter-gatherers in Peninsular Malaysia, and use it to test the effects of four predictors of lifetime reproductive success: (i) foraging return rate, (ii) sharing proclivity, (iii) cooperative foraging tendency, and (iv) kin presence.

Sex differences in empathy for pain have been repeatedly observed. However, it is unclear whether this is due to sex differences in "bottom-up" somatomotor representations of others' pain (self-other resonance) or to "top-down" prefrontal control of such responses. Here, we provide data from 70 subjects suggesting that sex differences in empathy for pain lie primarily in pre-reflective, bottom-up resonance mechanisms. Read More
