Since Piaget's contribution to the field, infant cognitive development and methods for its investigation have advanced considerably, with numerous psychologists investigating different areas of cognitive development including memory, language and perception, coming up with various theories [4] —for example Neo-Piagetian theories of cognitive ...
The reproduction of behaviors such as choosing one object over another or repeatedly placing an object in a certain spot is a type of situational memory test used to identify the child's level of memory capability. Deferred imitation, the ability to reproduce behaviour without cuing, can be seen and tested near the age of 18– 24 months.
The Mental and Social Life of Babies is a 1982 book by Kenneth Kaye.Integrating a contemporary burgeoning field of research on infant cognitive and social development in the first two years of life with his own laboratory's studies at the University of Chicago, Kaye offered an "apprenticeship" theory.
The Barnes maze is a tool used in psychological laboratory experiments to measure spatial learning and memory. The test was first developed by Dr. Carol Barnes in 1979. [ 1 ] The test subjects are usually rodents such as mice or lab rats , which either serve as a control or may have some genetic variable or deficiency present in them which will ...
It is difficult to develop an animal model that perfectly reproduces the symptoms of depression in patients. It is generic that 3 standards may be used to evaluate the reliability of an animal version of depression: the phenomenological or morphological appearances (face validity), a comparable etiology (assemble validity), and healing similarities (predictive validity).
Serotonin pathways are thought to modulate eating, both the amount as well as the motor processes associated with eating. The serotonergic projections into the hypothalamus are thought to be particularly relevant, and an increase in serotonergic signaling is thought to generally decrease food consumption (evidenced by fenfluramine , however ...
Part of this theory stems from much research into the major neurotransmitter, serotonin, which seems to show that major psychological illnesses such as bipolar disorder and anorexia nervosa are caused by abnormally reduced levels of Serotonin in the brain. [1] The model also suggests that psychological illness could and should be treated like ...
It has been observed that the pathology of depression involves dysfunction of monoamine neurotransmitter circuits in the CNS, particularly of serotonin and norepinephrine. Selective serotonin reuptake inhibitors (SSRIs) are the most widely used antidepressant and include fluoxetine (Prozac), citalopram (Celexa), and fluvoxamine (Luvox). These ...
