Hypertropia is a condition of misalignment of the eyes ( strabismus ), whereby the visual axis of one eye is higher than the fellow fixating eye. Hypotropia is the similar condition, focus being on the eye with the visual axis lower than the fellow fixating eye. Dissociated vertical deviation is a special type of hypertropia leading to slow ...
Hypertrophy is the increase in the volume of an organ or tissue due to the enlargement of its component cells. [ 1] It is distinguished from hyperplasia, in which the cells remain approximately the same size but increase in number. [ 2] Although hypertrophy and hyperplasia are two distinct processes, they frequently occur together, such as in ...
v. t. e. Behavioral neuroscience, also known as biological psychology, [ 1] biopsychology, or psychobiology, [ 2] is the application of the principles of biology to the study of physiological, genetic, and developmental mechanisms of behavior in humans and other animals. [ 3]
Far-sightedness, also known as long-sightedness, hypermetropia, and hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred. This blur is due to incoming light being focused behind, instead of on, the retina due to insufficient accommodation by the lens. [ 6]
Bielschowsky's head tilt test. Step 1: Determine which eye is hypertropic in primary position. If there is right hypertropia in primary position, then the depressors of the R eye (IR/SO) or the elevators of the L eye are weak (SR/IO). Step 2: Determine whether the hypertropia increases on right or left gaze.
The term ontogeny has also been used in cell biology to describe the development of various cell types within an organism. [4] Ontogeny is a useful field of study in many disciplines, including developmental biology, cell biology, genetics, developmental psychology, developmental cognitive neuroscience, and developmental psychobiology.
A psychological adaptation is a functional, cognitive or behavioral trait that benefits an organism in its environment. Psychological adaptations fall under the scope of evolved psychological mechanisms (EPMs), [2] however, EPMs refer to a less restricted set. Psychological adaptations include only the functional traits that increase the ...
In experimental psychology, a stimulus is the event or object to which a response is measured. Thus, not everything that is presented to participants qualifies as stimulus. For example, a cross mark at the center of a screen is not said to be a stimulus, because it merely serves to center participants' gaze on the screen.
