Background: Surgeon performance has been investigated as a factor affecting patient outcomes after orthopaedic procedures to improve transparency between patients and providers.
Purpose/hypothesis: The purpose of this study was to identify whether surgeon performance influenced patient-reported outcomes (PROMs) 1 year after arthroscopic partial meniscectomy (APM). It was hypothesized that there would be no significant difference in PROMs between patients who underwent APM from various surgeons.
This research investigated how an instance of intergroup helping affects intergroup attitudes and cooperative behavior. Past research demonstrates that helping behavior elicits prosociality, both reciprocally and toward uninvolved third parties. However, much of this research has either ignored group membership altogether or has assumed a shared group identity between benefactor and beneficiary.

While various national outcome measures have been developed and employed, no global consensus on standard measurement has been agreed for addiction. It is thus timely to build an international consensus.

- The amygdala plays a key role in how animals adapt behaviorally to threats, but its role in metabolic changes is less understood.
- Research shows that acute stress activates specific amygdala neurons that lead to higher blood sugar levels and reduced appetite, without relying on traditional hormonal signals.
- Repeated exposure to stress can impair this amygdala-liver communication, leading to issues like unstable blood sugar levels and weight gain, highlighting a link between stress and metabolic problems.
Humans and several other species of animals have demonstrated the ability to use familiarity to recognize that they have seen images before. In prior experiments, orangutans failed to show use of familiarity in memory tasks, even when other solutions were not available. We tested for evidence of habituation, a decreased response to repeated stimuli, as a behavioral indicator that repeated images were familiar to subjects.
