An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus
An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus
Theses and Dissertations
A dog was trained to respond deferentially to two light-sound compounds. The dog was then tested with combinations of additional light and sound intensities. The dog appeared to use the information provided by both stimulus dimensions. This research is relevant to the understanding of information processing, specifically categorization and generalization.

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …
The Influence Of Maternal Education On Lifetime Vulnerabilities For Chronic Stress And Heightened Physiological Reactions To Stressors, Hannah Lapp, Celia Moore, Kymberlee O'Brien
The Influence Of Maternal Education On Lifetime Vulnerabilities For Chronic Stress And Heightened Physiological Reactions To Stressors, Hannah Lapp, Celia Moore, Kymberlee O'Brien
Kymberlee M. O'Brien
We examined parental education as predictors of vulnerability to biological and perceived chronic stressors into adulthood. Measures included hair cortisol (hCORT) and cardiovascular parameters as indicators of chronic stress and overall health. The community subjective social status ladder was included to examine relationships between maternal education and assessments of social standing in adult offspring. Participants (N = 107; ages 18-30; M =22.23, SD = 3.01; 50.4% female) were recruited from an urban public university and residents of surrounding low-income areas in Boston, MA. Maternal and paternal education were positively associated with change in sympathetic nervous system (SNS) recovery after a …
Mediating Factors Of Perceived Discrimination: Physiological And Affective Markers., Kymberlee O'Brien, Edward Tronick, Celia Moore
Mediating Factors Of Perceived Discrimination: Physiological And Affective Markers., Kymberlee O'Brien, Edward Tronick, Celia Moore
Kymberlee M. O'Brien
Early life adversity influences later health and may be mediated by psychosocial, affective, and physiological stress and immune factors. We report evidence from MIDUS biomarker project (N = 845, age 34-84, M = 55.09, SD = 11.70) confirming the predicted relationship between early adversity and frequency of diagnosed chronic illnesses (M = 2.8, SD =1.2). Specific psychosocial and physiological variables were tested as mediators. Lifetime (M = .95, SD = 1.5) and daily (M = 12.8, SD = 1.2) discrimination, urinary cortisol (M = 1.1, SD = 1.2 ug/dL), IL-6 (M =2.8, SD = 2.8 pg/mL) (all ps<.001), and …
African-American Males' Perception Of Law Enforcement: A Psychophysiological Perspective, Adolph Brown Iii
African-American Males' Perception Of Law Enforcement: A Psychophysiological Perspective, Adolph Brown Iii
Psychology Theses & Dissertations
This study compared the psychophysiological reactivity of African American and European American males to authority. Nineteen African American males and 23 European American males were randomly assigned to either be interrogated by a police officer, or see a police officer interrogate that experimenter or view a videotape of police activity. Participants' physiological reactivity, acceptance of authority, fear of negative evaluation or social anxiety, and apprehension and anxiety in stressful situations as well as EMG, SCR, heart rate, respiration, and blood pressure were measured. African American males were hypothesized to show greater physiological response than European American males and participants who …
