Stimulus representation: a subprocess of imprinting and conditioning.

We suggest a way to reconcile imprinting and associative learning that respects the real differences between the two phenomena but helps to recognize underlying commonalities. Rather than treating each type of learning as the manifestation of a unitary mechanism, we approach learning as a combination of separate subprocesses. Exploration of the literature regarding one of these subprocesses, namely, that governing the representation of stimuli, revealed striking similarities between imprinting and conditioning. These similarities suggest predictions for fresh experimental work that will help to uncover the general rules by which combinations of stimulus features are represented in memory.

Timing of presentation of prenatal auditory stimulation alters auditory and visual responsiveness in bobwhite quail chicks (Colinus virginianus).

One group of bobwhite quail embryos (Colinus virginianus) was exposed to 10 min/hr of bobwhite chick contentment calls immediately followed by 10 min/hr of bobwhite chick distress calls. A 2nd group of embryos was exposed to the same auditory stimulation but in the opposite order of presentation. Postnatal testing revealed that chicks exposed prenatally to the bobwhite chick contentment call and distress call (in either order of presentation) continued to respond to maternal auditory cues into later stages of postnatal development compared with unmanipulated chicks. Chicks exposed prenatally to the contentment call followed by the distress call showed an accelerated pattern of visual responsiveness to maternal cues, whereas chicks exposed prenatally to the distress call followed by the contentment call showed deficits in the normal pattern of perceptual visual responsiveness, suggesting that the auditory stimulation precocial avian embryos encounter 1st is influential in directing early intersensory development.

Modified sensory features of social stimulation alter the perceptual responsiveness of bobwhite quail chicks (Colinus virginianus).

This study examined the sensory features of postnatal social experience that bobwhite quail chicks (Colinus virginianus) require to maintain species-typical responding to maternal auditory-visual cues. Chicks were reared in 1 of 3 conditions after hatching: altered tactile, auditory, or visual experience with siblings. Findings revealed that altered tactile, auditory, or visual experience during the first 36 or the first 72 hr following hatching modified chicks' preferential responding to species-specific maternal cues. During the second 36 hr, altered tactile or auditory experience disrupted chicks' perceptual development, whereas altered visual experience did not affect species-typical responsiveness. Results indicate that (a) timing of early postnatal visual experience can affect early filial responsiveness to maternal cues and (b) normal sensory experience derived from early social interaction affects species-typical perceptual development.
