Temperature preference of Nile tilapia (Oreochromis niloticus) juveniles induces spontaneous sex reversal.

PLoS ONE, 2019
Nile tilapia (Oreochromis niloticus) is an African freshwater fish that displays a genetic sex determination system (XX|XY) where high temperatures (above 32°C to 36.5°C) induce masculinization.

Stochastic representation decision theory: How probabilities and values are entangled dual characteristics in cognitive processes.

PLoS ONE, 2020
Humans are notoriously bad at understanding probabilities, exhibiting a host of biases and distortions that are context dependent. This has serious consequences on how we assess risks and make decisions.

Appetitively motivated tasks in the IntelliCage reveal a higher motivational cost of spatial learning in male than female mice

Frontiers in Behavioral Neuroscience
The IntelliCage (IC) permits the assessment of the behavior and learning abilities of mice in a social home cage context. To overcome water deprivation as an aversive driver of learning, we developed protocols in which spatial learning is motivated ...

Evolution of similarity judgements in intertemporal choice [PDF]

, 2014
We study Nature's trade-off when endowing people with the cognitive ability to distinguish between different time periods or different prizes. Our key premise is that cognitive ability is a scarce resource, to be deployed only where and when it really ...

Taking a radical position: Evidence for position specific radical representations in Chinese character recognition using masked priming ERP

Frontiers in Psychology, 2012
In the investigation of orthographic representation of Chinese characters, one question that has stimulated much research is whether radicals (character components) are specified for spatial position in a character (e.g.

Continuum model for chiral induced spin selectivity in helical molecules

, 2015
A minimal model is exactly solved for electron spin transport on a helix. Electron transport is assumed to be supported by well oriented $p_z$ type orbitals on base molecules forming a staircase of definite chirality.

Predation risk reduces a female preference for heterospecific males in the green swordtail [PDF]

, 2016
The presence of a predator can result in the alteration, loss or reversal of a mating preference. Under predation risk, females often change their initial preference for conspicuous males, favouring less flashy males to reduce the risk of being detected ...

Rethinking the Discount Factor in Reinforcement Learning: A Decision Theoretic Approach

, 2019
Reinforcement learning (RL) agents have traditionally been tasked with maximizing the value function of a Markov decision process (MDP), either in continuous settings, with fixed discount factor $\gamma < 1$, or in episodic settings, with $\gamma = 1 ...
