Rats show socially selective helping behavior based on familiarity with the type of rat, but not necessarily the individual rat.

Call-based vocal communication of individually recorded zebra finches changes in social groups across reproductive stages and is related with successful egg laying.

Understanding others' pain is grounded in cognitive rather than sensory faculties.

The subjective time of social interactions reflects one's autistic-like tendency and is critically mediated by oxytocin, indicating that time perception is ingrained with personality traits, which likely have neuroendocrine origins as per previous research.

Regulatory success operates by goal-consistent increases and decreases of distinct attribute representations in generic neural hubs and in domain-specific brain regions, explaining when and why regulatory success generalizes across domains and contexts.

A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.

Rat behavior and dopamine release are preferentially modulated by subjective rather than objective evaluation of outcomes in a social setting.

Neurocognitive processing during sleep selectively biases subjective preferences in simple economic choices when the sleeper is stimulated by covert, reward-associated cues.

Disrupting the right temporo-parietal junction did not change the general motivation to give or adapt behavior to social reputation cues, but specifically reduced the impact of moral-material conflict.

Humans intranasally administered the neuropeptide oxytocin waste less and earn more spoils during intergroup conflict because oxytocin enables group members to better coordinate strategic attacking of out-groups.
