Q

The ability to conceptualize a new action to be performed in a given situation (Ayres, 1981, 1985). This aspect of praxis involves generating an idea of what to do. It precedes motor planning, which addresses the plan for how to perform the action.

Q

A sensory modulation condition in which the individual tends to ignore or be relatively unaffected by sensory stimuli to which most people respond. In some cases, the person may have an excessive craving for intense stimuli. Used interchangeably with the term under-responsiveness.

Q

A sensory modulation condition in which the individual is disturbed by ordinary sensory input and reacts to it defensively or fearfully, often with strong negative emotion, avoidance, and activation of the sympathetic nervous system. Used interchangeably with the terms over-responsiveness and defensiveness.

Q

The ability to distinguish between different sensory stimuli. This term is usually used to refer to the ability to make fine distinctions between stimuli within one sensory modality, such as discriminating between two points of tactile contact or differentiating between similar sounds. It is sometimes also used to include the central process of organizing temporal and spatial characteristics of sensory stimuli (Miller & Lane, 2000).

Q

set of complex central nervous system processes by which neural messages that convey information about the intensity, frequency, duration, complexity, and novelty of sensory stimuli are adjusted (Miller & Lane, 2000). Behaviorally, this is manifested in the tendency to generate responses that are appropriately graded in relation to incoming sensations, neither underreacting nor overreacting to them.

Q

A sensory modulation condition in which the individual actively seeks out particular kinds of sensations at higher frequencies or intensities than is typical. Sensory seeking may occur for a number of different reasons, including compensation for poor perception, under-responsiveness, or over-responsiveness in one or more sensory systems, or limited movement strategies due to praxis problems. It may also be an expression of temperament or personality. Sometimes called sensation seeking.

Q

The process by which the central nervous system attends to stimuli; this usually involves an orienting response. Sensory registration problems are characterized by failure to notice stimuli that ordinarily are salient to most people.

A

Sensory registration

17
Q

The organization of sensation for use (Ayres, 1979); a complex set of processes in the central nervous system that are involved in sensory modulation, perceptual, and praxic functions. This term is also used to refer to an occupational therapy practice approach (OT-SI) designed to help children who have difficulty with these neural functions.

A

Sensory processing

18
Q

term referring generally to the handling of sensory information by neural systems, including the functions of receptor organs and peripheral and central nervous systems. This includes the processes of reception, modulation, integration, and organization of sensory stimuli, including behavioral responses to stimuli (Miller & Lane, 2000)

A

Sensory integration

19
Q

The ability to appropriately order a series of actions, an important element of motor planning. This term also is sometimes used to refer to the ability to replicate a series of sensory stimuli in the correct order.

A

Sequencing

20
Q

An aspect of praxis that is heavily dependent on somatosensory processing (Ayres, 1989). An impairment of this aspect of praxis is termed somatodyspraxia (Cermak, 1991) and is characterized by poor tactile and proprioceptive processing as well as poor praxis.

A

Somatopraxis

21
Q

A term sometimes used interchangeably with sensory over-responsiveness. It may also refer to a temperament quality or individual difference in which the person tends to notice or be distracted by stimuli that most people would not notice (Dunn, 2001). In neuroscience, the conventional use of this term is in reference to the lowest point of intensity at which a person detects the presence of a sensory stimulus (Lundy-Ekman, 2013).

A

Sensory Sensitivity

22
Q

Pertaining to the tactile and proprioceptive systems.

A

Somatosensory

23
Q

Pertaining to the inner ear receptors in the semicircular canals and otolith organs that detect head position and movement as well as gravity.

A

Vestibular

24
Q

problems are indicated by low scores on visual perception tests, along with difficulty replicating two-dimensional designs with paper and pencil, or difficulty with 
three-dimensional constructions such as building with blocks.

A

Visuopraxis

25
Q

A sensory modulation condition in which the individual fails to notice or is relatively unaffected by sensory stimuli to which most people respond. Used interchangeably with the term hypo-responsiveness.

A

Under-responsiveness

26
Q

A type of over-responsiveness in which there is a tendency to react negatively and emotionally to touch sensations (Ayres, 1979).

A

Tactile defensiveness
