5- And 8-Month-Olds’ Visual Exploration Of 2d Scenes: The Relative Impact Of Object Size, Object Detail, And Depth Cue On Infants’ Visual Attention, Yu Guan

Doctoral Dissertations

How infants visually explore complex scenes containing objects varying in size, depth cues, and amount of detail is still an open question. When infants are presented with a complex scene, we do not know which dimensions of the scene are more likely to catch their attention first, and which are more likely to sustain their looking duration the most. This study aimed to investigate how infants’ explore 2D displays containing different combinations of object size, depth cues, and detail.

In experiment 1, forty infants (twenty of 5 months old and twenty of 8 months old) were presented with stimuli containing …

Infants’ Responses To Affect In Music And Speech, Daniel K. Feinberg

Pitzer Senior Theses

Existing literature demonstrates that infants can discriminate between categories of infant-directed (ID) speech based on the speaker’s intended message – that is, infants recognize the difference between comforting and approving ID speech, and treat different utterances from within these two categories similarly. Furthermore, the literature also demonstrates that infants understand many aspects of music and can discriminate between happy and sad music. Building on these findings, the present study investigated whether exposure to happy or sad piano music would systematically affect infants’ preferences for comforting or approving ID speech. Five- to nine-month-old infants’ preferences for comforting or approving ID speech …

Infant Perceptions Of Mixed-Race Faces: An Exploration Of The Hypodescent Rule In 8.5 Month-Old Infants, Sophie Beiers

Pitzer Senior Theses

Studies have shown that adults often categorize mixed-race individuals of White and non-White descent as members of the non-White racial group, an effect said to be reminiscent of the “hypodescent” or “one-drop rule.” This effect has not yet been thoroughly studied in infants, although 9-month-old infants have been shown to be able to categorize mono-racial faces into different racial groups. In the present study, the perception of mixed-race White and Asian/Asian American faces was studied in sixteen 8.5-month-old infants. The infants were randomly assigned to two stimulus groups. The stimuli were the photographed faces of female college students who had …
