The host is often the personality that seeks treatment. [1] Therefore, the psychotherapists often deal primarily with the host personality. Part of the therapeutic process for DID involves helping the host recognize the alters and become aware when the alters are present. [5] In some cases, the host is unaware of any alters or even that they ...
Host factors that may vary in a population and affect disease susceptibility can be innate or acquired. Some examples: [1] general health; psychological characteristics and attitude; nutritional state; social ties; previous exposure to the organism or related antigens; haplotype or other specific genetic differences of immune function ...
A virus can enter a susceptible cell, but it may or may not be able to replicate. A virus may only replicate in a permissive cell. Viral replication will therefore occur in a susceptible cell which is also a permissive cell that 1) facilitates entry (susceptibility) and 2) supports intracellular replication (permissive cell).
The idea that individuals vary in their sensitivity to their environment was historically framed in diathesis-stress [4] or dual-risk terms. [5] These theories suggested that some "vulnerable" individuals, due to their biological, temperamental and/or physiological characteristics (i.e., "diathesis" or "risk 1"), are more vulnerable to the adverse effects of negative experiences (i.e., "stress ...
For example, a participant will be asked whether their birth year is even and whether they have performed an illegal activity; if yes to both or no to both, to select A, and if yes to one but no to the other, select B. By combining sensitive and non-sensitive questions, the participant's response to the sensitive item is masked.
The behavioral immune system is a phrase coined by the psychological scientist Mark Schaller to refer to a suite of psychological mechanisms that allow individual organisms to detect the potential presence of infectious parasites or pathogens in their immediate environment, and to engage in behaviors that prevent contact with those objects and individuals.
Spontaneous recovery is associated with the learning process called classical conditioning, in which an organism learns to associate a neutral stimulus with a stimulus which produces an unconditioned response, such that the previously neutral stimulus comes to produce its own response, which is usually similar to that produced by the unconditioned stimulus.
Host–parasite coevolution is a special case of coevolution, where a host and a parasite continually adapt to each other. This can create an evolutionary arms race between them. A more benign possibility is of an evolutionary trade-off between transmission and virulence in the parasite, as if it kills its host too quickly, the parasite will ...
