Taylor Vigfusson PSY 340 23 March 2020 ATQ2 1.From this information, medium sounds are the least difficult for infants to detect. This is because for infants and adults, their hearing gets better between 500 and 2,000 Hz, and 2,000 Hz is the best frequency for hearing. When the frequency reaches 2,000 Hz, infants are able to hear it better at a lowest threshold. 2.A stimulus pair that infants do not discriminate from the figure are the plus sign and circle. I can tell they do not discriminate because the average seconds of fixation are almost equal for the two, and this could either be because they cannot tell the difference between the two or they simply prefer looking at both equally. 3.The conclusions that follow from the looking times shown for Experiment 1 and 2 are that infants have a preference for features in an upright position, and they prefer a top-heavy configuration compared to a bottom-heavy configuration based on the fixation times.
