Fixation (visual)Fixation or visual fixation is the maintaining of the gaze on a single location. An animal can exhibit visual fixation if it possesses a fovea in the anatomy of their eye. The fovea is typically located at the center of the retina and is the point of clearest vision. The species in which fixational eye movement has been verified thus far include humans, primates, cats, rabbits, turtles, salamanders, and owls.
Validity (statistics)Validity is the main extent to which a concept, conclusion, or measurement is well-founded and likely corresponds accurately to the real world. The word "valid" is derived from the Latin validus, meaning strong. The validity of a measurement tool (for example, a test in education) is the degree to which the tool measures what it claims to measure.
AttentionPsychological focus, perception and prioritising discrete informationFocused attentionAttention is the concentration of awareness directed at some task or phenomenon while mostly excluding others. Across disciplines, the nature of this directedness is conceptualized in different ways. In cognitive psychology, attention is often described as the allocation of limited cognitive processing resources to a subset of information, thoughts, or tasks.
CuriosityCuriosity (from Latin cūriōsitās, from cūriōsus "careful, diligent, curious", akin to cura "care") can be a quality related to inquisitive thinking, such as exploration, investigation, and learning, evident in humans and other animals. It can also refer to something (an event, object, person, etc.) which can cause curiosity.
ProcessA process is a series or set of activities that interact to produce a result; it may occur once-only or be recurrent or periodic.
Sexual attractionSexual attraction is attraction on the basis of sexual desire or the quality of arousing such interest. Sexual attractiveness or sex appeal is an individual's ability to attract other people sexually, and is a factor in sexual selection or mate choice. The attraction can be to the physical or other qualities or traits of a person, or to such qualities in the context where they appear. The attraction may be to a person's aesthetics, movements, voice, among other things.Facial expressionFacial expression is a motion and positioning of the muscles beneath the skin of the face. These movements convey the emotional state of an individual to observers and are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species.
Brain–computer interfaceConnection between brain and computerParticipant in a brain-computer interface getting connected to a computerDummy unit illustrating the design of a BrainGate interfaceA brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a system that measures brain activity and translates it into functionally useful outputs, allowing interaction with an external or internal system, most commonly a computer or robotic limb.
Eye trackingMeasuring the point of gaze or motion of an eye relative to the headEye tracking deviceScientists track eye movements in glaucoma patients to check vision impairment while driving.Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement.
Eye movement in readingEye movement in reading involves the visual processing of written text. This was described by the French ophthalmologistLouis Émile Javal in the late 19th century. He reported that the eyes do not move continuously along a line of text, but make short, rapid movements (saccades) intermingled with short stops (fixations). Javal's observations were characterised by a reliance on naked-eye observation of eye movement in the absence of technology.
MydriasisMydriasis is the dilation of the pupil, usually having a non-physiological cause, or sometimes a physiological pupillary response. Non-physiological causes of mydriasis include disease, trauma, or the use of certain types of drugs. It may also be of unknown cause. Normally, as part of the pupillary light reflex, the pupil dilates in the dark and constricts in the light to respectively improve vividity at night and to protect the retina from sunlight damage during the day.*As an Amazon Associate I earn from qualifying purchases.
