Top down vs bottom up psychology7/27/2023 It is, therefore, not possible to confirm from these results that top-down effects modulate perception in infants or adults. Infants likewise showed no improvement in perceptual abilities as a result of a sound cue in addition to chance-level face recognition. It was found that, while adults do show a visibility curve similar to the one found in previous work (Gelskov & Kouider, 2010), their perception is not modulated by top-down influences. Both adults and infants between the ages of 10 months and 12 months and 29 days were tested using this paradigm. Using the visibility curves established for adults and infants in a previous study as the basis for experimental design (Gelskov & Kouider, 2010), it was hypothesized that pairing the presentation of a face stimulus with a preceding auditory cue would create an expectation that elicited top-down modulation of perception, making infants and adults better at seeing faces when presented for a short amount of time than they otherwise would be. This study tests the relationship between top-down processing and face recognition in infants. This shift in attentional mechanisms could affect important processes like face perception but it has yet to be tested whether there are top-down effects in face perception in infancy and when they emerge. We use bottom-up processing, the automatic scanning of our surroundings, to take in stimuli, while top-down processes can guide attention to particular features in sensory input to improve perception. It is vital in creating associations that lead to predictions and facilitate processing. Top-down processing involves the voluntary processing of a stimulus triggered by some cue that focuses attention. It has been presumed that some time towards the end of their first year of life a shift occurs, and infants begin to use top-down processing in addition to bottom-up. Initially in life, infants use bottom-up processing, the automatic attentional process of scanning one’s surroundings, to perceive the stimuli that are most salient to them.

A dual approach (top-down and bottom-up) deals with the underlying issues and has more lasting results. We only become more aware of this after we strengthen and grow the thinking brain.
