Does Having Siblings Affect Caretaking Responses To Infants?, Kaitlin Rose Duskin
Does Having Siblings Affect Caretaking Responses To Infants?, Kaitlin Rose Duskin
Cal Poly Humboldt theses and projects
Infant facial cues affect a variety of caretaking-related responses in adults. These effects have primarily been explored as they relate to parental care, however infants receive care from others who are not their parents and it would be important for any caregiver, regardless of parental status, to respond to infant cues effectively. Because siblings often fulfill a caregiver role in the home, this study investigated whether having siblings, younger siblings in particular, influences the way in which adults respond to infant cues. Contrary to my predictions, the findings in this study indicate that having siblings does not influence how rewarding …
Does The Thatcher Effect Extend To Infant Faces?, Sarang Jew
Does The Thatcher Effect Extend To Infant Faces?, Sarang Jew
Cal Poly Humboldt theses and projects
Decades of research on the mechanisms of face processing have demonstrated that humans rely heavily on configural processing strategies when viewing faces. However, this work has been done using almost exclusively adult facial stimuli. More recently, researchers have proposed that infant faces may elicit different neural activity and behavioral responses than adult faces. These observed differences may start at the very early stages of face processing (i.e., the structural encoding occurring within 200ms of seeing a face). However, no studies to date have explored potential differences in processing strategies used for infant faces compared to adult faces. The current study …

Hormonal Medications And Partner Odor Preferences, Jeffrey Lee Frederick
Cal Poly Humboldt theses and projects
The ability to recognize kin through the olfactory sense has important survival and evolutionary implications when choosing mates. Failing to recognize kin when making a choice of whom to mate with can lead to an increase in detrimental genetic outcomes in offspring. Previous studies have indicated that normally ovulating heterosexual women and men prefer the body odor of those with dissimilar immune systems than those with similar immune systems. The use of hormonal contraceptives has shown a preference for similar immune system odors. The current study examines whether the use of hormonal medications predicts preference for body odor. Importantly, this …
