ACCOMMODATION IN FISHES

Convergence accommodation.

Steady-state accommodation responses were measured in both eyes as a function of vergence angle and direction of lateral gaze. The measurements were made with a binocular laser optometer. Small speckle patterns were used as fusional stimuli in an otherwise dark field. These patterns have the advantage of providing no blur stimulus to accommodation. Convergence accommodation for vergence angles ...

Accommodation in Binocular Contour Rivalry

Although contour rivalry is known to suppress the contribution of the non-dominant eye to some visuomotor mechanisms such as the pupillary light reflex, there have been no reports of the impact of rivalry on accommodation control. In the situation where the accommodation demands in the two eyes are in dynamic conflict, it has been reported that the accommodation response can be modelled in term...

Presupposition Accommodation in Update Semantics

The study of presuppositions lies on the border of semantics and pragmatics. It concerns information, assumed to be part of the discourse context by the speaker, as apparent in the syntactic form of the utterance. Missing presupposed information will normally be lled in by the hearer, provided it is compatible with the context. My thesis tries to characterise this process of presupposition acco...

Dynamic accommodation in rhesus monkeys

The dynamics of Edinger-Westphal (EW) stimulated accommodation were studied in two young rhesus monkeys to understand the relationships between accommodative amplitude and rates of accommodation and disaccommodation. Accommodative responses were recorded with infrared photorefraction at five different amplitudes spanning the full EW stimulated accommodative range available to each eye. Combined...
