Effects of oral contraceptives and natural menstrual cycling on environmental learning.

Background: Endogenous ovarian hormones as well as exogenous oestradiol and progesterone play an important role in cognitive processing. Specifically, these hormones play a role in different aspects of memory, both in terms of storage capacity and temporal duration of the mnemonic track. These hormones also have various effects on different types of memory (i.

Effect of professional expertise and exposure to everyday life decision-making on moral choices.

Moral sense is defined as a feeling of fairness or unfairness of an action that knowingly causes harm to people other than the subject. It is crucial in determining human behavior and becomes pivotal in operational environments. Here we assessed whether professional daily life experience in an operational environment affects moral judgment by asking 41 military pilots of the Italian Air Force (P) and 69 controls (C) to solve 40 moral dilemmas.

Cognitive Reserve in Healthy Aging and Alzheimer's Disease: A Meta-Analysis of fMRI Studies.

Cognitive reserve (CR) has been defined as the ability to optimize or maximize performance through differential recruitment of brain networks. In the present study, we aimed at providing evidence for a consistent brain network underpinning CR in healthy and pathological aging. To pursue this aim, we performed a coordinate-based meta-analysis of 17 functional magnetic resonance imaging studies on CR proxies in healthy aging, Alzheimer's disease (AD), and mild cognitive impairment (MCI).

Domain-Specific Interference Tests on Navigational Working Memory in Military Pilots.

Introduction: Human navigation is a very complex ability that encompasses all four stages of human information processing (sensory input, perception/cognition, selection, and execution of an action), involving both cognitive and physical requirements. During flight, the pilot uses all of these stages and one of the most critical aspect is interference. In fact, spatial tasks competing for the same cognitive resource cause greater distraction from a concurrent task than another task that uses different resource modalities.
