- Asynchronous Control (Self-Paced Control, Asynchronous BCI)
- A mode of interaction with a computer or assistive device where the user can issue commands at any time of their choosing, rather than being constrained to respond within system-defined time windows. …
- Asynchronous Learning (Asynchronous Instruction)
- A mode of education in which learners engage with instructional content on their own schedule rather than in real time with an instructor, typically via pre-recorded videos, written materials, or inte…
- At-Risk Populations (Vulnerable Populations)
- Groups that are more likely to experience harm from digital attacks, surveillance, institutional discrimination, or other threats, and are disproportionately affected when such harms occur. Originally…
- Ataxia (Cerebellar Ataxia)
- A neurological condition characterized by impaired coordination and control of voluntary movements, typically caused by damage to the cerebellum or its connections. People with ataxia may experience u…
- Ataxia-Telangiectasia (A-T, Louis-Bar Syndrome)
- A rare, inherited, progressive neurological disorder that typically appears in early childhood and causes increasing difficulties with movement, coordination, and immune function. Children with A-T us…
- Athetoid (Athetosis, Athetoid Movement)
- A type of involuntary movement characterised by slow, continuous, writhing motions, particularly affecting the hands, fingers, and face. Athetoid movements are commonly associated with athetoid cerebr…
- Athetoid Cerebral Palsy (dyskinetic cerebral palsy, athetosis)
- A type of cerebral palsy characterized by involuntary, slow, writhing movements (athetosis) that affect the face, trunk, and limbs. It accounts for about 10-15% of cerebral palsy cases and results fro…
- Athetoid Cerebral Palsy (Dyskinetic Cerebral Palsy, Athetosis)
- A form of cerebral palsy characterized by involuntary, uncontrolled, slow writhing movements, particularly affecting the hands, feet, arms, and legs, and sometimes the muscles of the face and tongue. …
- Athetosis (Athetoid movements)
- A movement disorder characterized by slow, involuntary, writhing movements, particularly affecting the hands, feet, and face. Athetosis is one form of dyskinetic cerebral palsy and results from damage…
- Atomic Facts (Atomic Claims)
- Self-contained units of information extracted from longer text, each representing a single verifiable claim or observation. In AI reliability research, decomposing model responses into atomic facts en…
- Attention (Attentional processing, Selective attention)
- The cognitive process of selectively focusing on relevant stimuli while filtering out competing information. Cognitive neuroscience typically decomposes attention into three networks: alerting (mainta…
- Attention Capture Pattern (Attention Capture, Attention Grabbing Design)
- A design element on a website intentionally crafted to draw users' attention toward content that serves the site's interests rather than the user's goals. Examples include bright promotional banners, …
- Attention Deficit (Attention Deficit Disorder, ADD, Attention Deficit Hyperactivity Disorder, ADHD)
- A cognitive condition characterised by difficulty sustaining focus, filtering distractions, and maintaining concentration on tasks. Attention deficits are common following traumatic brain injuries and…
- Attention Deficit Hyperactivity Disorder (ADHD)
- A neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with functioning and development. ADHD affects approximately 7.6% of ch…
- Attention Management (Attention Design)
- Design strategies and techniques that help users direct, maintain, and recover attention while interacting with digital content. For users with ADHD, attention management in interface design includes …
- Attention Mechanism (Attention)
- A technique in neural networks that allows models to focus on relevant parts of the input when generating each part of the output, rather than relying solely on a fixed-length context vector. In seque…
- Attention Network Test (ANT, ANT-I, ANT-Child)
- A computer-administered cognitive task developed by Fan, Posner, and colleagues that measures three functionally distinct attention networks — alerting (sustained readiness), orienting (shifting atten…
- Attention Restoration (Attention Restoration Theory, ART)
- A theoretical framework proposing that directed attention is a finite cognitive resource that becomes depleted through effortful focus and is restored through exposure to environments or activities th…
- Attention Tunneling (Visual Tunneling, Attentional Tunneling, Cognitive Tunneling)
- A phenomenon in which a user concentrates so narrowly on a primary information source - typically a visual overlay, head-up display, or instrument - that they fail to notice relevant events, objects, …
- AuDHD (Autism and ADHD co-occurrence)
- A term used by the neurodivergent community to describe the co-occurrence of autism spectrum disorder and attention deficit hyperactivity disorder in the same individual. Research suggests significant…
