Space-luminance crossmodal correspondences in domestic chicks

Two morphologically distinct trypanosomes (Trypanosoma ontarioensis n.sp. and Trypanosoma paddae) were found by the haematocrit centrifuge technique in the blood of 53% (64 of 121) of Corvus brachyrhynchos brachyrhynchos wintering in southern Ontario. Trypanosoma ontarioensis n.sp. is a small trypanosome with subterminal kinetoplast. It is monomorphic and not host specific. It was readily cultured in diphasic blood-agar medium. Two-week cultures were infective and contained dividing sphaeromastigotes, epimastigotes, and trypomastigotes. Blood trypomastigotes were detected in low numbers in the blood of inoculated birds (Corvus brachyrhynchos brachyrhynchos, Bonasa umbellus, Gallus domesticus, Melopsittacus undulatus, and Serinus canarius) at 28 and 48 days postinfection. The crows, ruffed grouse, and domestic chicks were laboratory raised while the budgerigars and canaries were from pet stores. One canary that was further examined at 180, 360, 540, 730, and 910 days postinfection still had detectable numbers of trypanosomes in its blood.

First Time

AbstractDomestic chicks were placed in isolation under a constant white light for 30 minutes. Afterwards these birds and a group previously kept in the dark were trained with a Red or a Yellow flashing light for 45 minutes. Subsequently all chicks were given a choice between familiar and unfamiliar flashing lights in some new apparatus which is described in detail for the first time. The chicks exposed to constant light showed a clear preference for the flashing light with which they had been trained whereas the Dark control chicks did not. It is suggested that the constant light activated their visual pathways enabling the Light-exposed chicks to learn more than the Dark control chicks during the imprinting procedure.

Figure Test

Crossmodal correspondences are the automatic associations that most people have between different basic sensory stimulus attributes, dimensions, or features. For instance, people often show a systematic tendency to associate moving objects with changing pitches. Cognitive styles are defined as an individual’s consistent approach to think, perceive, and remember information, and they reflect qualitative rather than quantitative differences between individuals in their thinking processes. Here we asked whether cognitive styles played a role in modulating the crossmodal interaction. We used the visual Ternus display in our study, since it elicits two distinct apparent motion percepts: element motion (with a shorter interval between the two Ternus frames) and group motion (with a longer interval between the two frames). We examined the audiovisual correspondences between the visual Ternus movement directions (upward or downward) and the changes of pitches of concurrent glides (ascending frequency or descending frequency). Moreover, we measured the cognitive styles (with the Embedded Figure Test) for each participant. The results showed that congruent correspondence between pitch-ascending (decreasing) glides and moving upward (downward) visual directions led to a more dominant percept of ‘element motion’, and such an effect was typically observed in the field-independent group. Importantly, field-independent participants demonstrated a high efficiency for identifying the properties of audiovisual events and applying the crossmodal correspondence in crossmodal interaction. The results suggest cognitive styles could differentiate crossmodal correspondences in crossmodal interaction.
