Forming a concept involves selecting the important characteristics of our experiences and categorising them.

The Neitzes, with Katherine Mancuso and other colleagues, used the technique of gene therapy to introduce the gene for the missing red pigment into the cone cells of the monkeys’ retinas. Several months after the therapy, Dalton and Sam were able to see a world in which red hues were visible and oranges no longer looked like lemons, the researchers say in the current issue of Nature.
there is growing evidence that animals share functional parallels with human conscious metacognition -- that is, they may share humans' ability to reflect upon, monitor or regulate their states of mind.
Results indicated that greater religiosity was associated with greater trust in the U.S. Supreme Court to decide this issue, and that stronger moral convictions about physician-assisted suicide were associated with greater distrust in the U.S. Supreme Court to decide this issue. Also, the processes underlying religious trust and distrust based on moral convictions were more quick and visceral than slow and carefully considered.
To observe neurotransmitter uptake and release from individual presynaptic terminals directly, we designed fluorescent false neurotransmitters as substrates for the synaptic vesicle monoamine transporter.
Envy and schadenfreude (gloating over the other's misfortune) are social emotions widely agreed to be a symptom of the human social tendency to compare one's payoffs with those of others. Given the important social components of envy and gloating, we speculated that oxytocin may have a modulating effect on the intensity of these emotions.
