Internalism (education)
The view that an educational account should focus on the beliefs and practices of teachers and learners without reference to the interpretations available in allied disciplines in the social sciences, including psychology. See Externalism, Interdisciplinarity
Internal consistency
Internal consistency refers to an important requirement for composite scales, in which the individual items or tests making up the scale are statistically associated with each other. If so, then it can be assumed that they are all measuring the same construct or attribute. It is important to note that measures of internal consistency do …
Internal speech
Sub-vocal speech articulation. Highly self-aware individuals use inner speech significantly more frequently compared to less self-aware individuals. Brain-imaging studies have shown that inner speech is associated with activation of the left inferior frontal area. In contrast, the monitoring of one’s own speech (auditory verbal imagery), by means of imagining the sentences they generated when spoken …
Internal capsule
White matter located between the basal ganglia and the thalamus and through which the lateral and medial bundles of the corticospinal tracts descend to the spinal cord (see figure below for further details). Fibers from the motor cortex join fibers from other areas of the cortex (viz., the corona radiate) to form a bundle of …
Intermodal coordination
The ability to associate sensory input from one modality to that of another. See Active intermodal matching, Amodal, Cross-modal coordination, Cross-modal matching, Intermodal perception, Intersensory redundancy hypothesis, Lateral geniculate nucleus (or body)
Intermodal perception
Perceiving relationships among different types of sensory input. The development of intermodal perception has been reviewed in a large number of papers over the years. See Active intermodal matching, Amodal, Intermodal coordination, Intersensory redundancy hypothesis, Perceptual development
Interdiscipline
A coming together of two or more established disciplines to tackle an issue or problem of common interest that is perceived as being irresolvable within the confines of a single discipline. Existing at the interstices of disciplines, it may as Thomas S. Kuhn (1922-1996) once said, develop into new discipline with its own borders and …
Interdigital necrotic zone (INZ)
The regions lying between the newly forming digits, where ‘programmed’ cell death (apoptosis) occurs (see figure below). Interdigital necrotic zone (left) and the outcome of apoptosis some 15 days later (right). See Apoptosis, Cell death
Interdisciplinarity
In a general sense, it involves all attempts to reorganize and integrate scientific knowledge along lines other than those defined by the specializations of contemporary disciplines.
