Sociobiology is based on the premise that some behaviors (social and individual) are at least partly inherited and can be affected by natural selection. [ 7 ] It begins with the idea that behaviors have evolved over time, similar to the way that physical traits are thought to have evolved. It predicts that animals will act in ways that have ...
A prominent example of pulse-rate generational theory is Strauss and Howe's theory. Social scientists tend to reject the pulse-rate hypothesis because, as Jaeger explains, "the concrete results of the theory of the universal pulse rate of history are, of course, very modest. With a few exceptions, the same goes for the partial pulse-rate theories.
In medicine, a pulse represents the tactile arterial palpation of the cardiac cycle (heartbeat) by fingertips. The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint (posterior ...
The Red Queen's hypothesis is a hypothesis in evolutionary biology proposed in 1973, that species must constantly adapt, evolve, and proliferate in order to survive while pitted against ever-evolving opposing species. The hypothesis was intended to explain the constant (age-independent) extinction probability as observed in the paleontological ...
t. e. Social dynamics (or sociodynamics) is the study of the behavior of groups and of the interactions of individual group members, aiming to understand the emergence of complex social behaviors among microorganisms, plants and animals, including humans. It is related to sociobiology but also draws from physics and complex system sciences.
Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval. Other terms used include "cycle length variability", "R–R variability" (where R is a point corresponding to the peak of the QRS complex of the ECG wave; and R–R is ...
A number of methods are used in social neuroscience to investigate the confluence of neural and social processes. These methods draw from behavioral techniques developed in social psychology, cognitive psychology, and neuropsychology, and are associated with a variety of neurobiological techniques including functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), positron ...
[1] [3] Both concepts play an important role in science and engineering, including biology, chemistry, and cybernetics. Mathematically, positive feedback is defined as a positive loop gain around a closed loop of cause and effect. [1] [3] That is, positive feedback is in phase with the input, in the sense that it adds to make the input larger.
