Removal of a single testis results in hypertrophy of the remaining gonad (compensatory testicular hypertrophy; CTH) in juveniles and adults of many mammalian species. CTH is thought to be mediated in part by post-castration decreases in negative feedback from the testes onto the…

Circadian rhythms in the Syrian hamster can be adjusted by inducing the animal to become active during its usual sleep period. This type of clock resetting is distinct from clock resetting by light, and is thus known as nonphotic phase shifting. Although the prevailing view has …
This dissertation consists of two studies. The first study assessed the current attitudes of government employees and college students toward persons with disabilities, and explored the relationship to attitude of salient demographic variables such as: gender, age, education, wo…
The perception of time is one of the hallmarks of conscious experience. However, despite this importance, time is a relatively understudied dimension in psychology and cognitive neuroscience. A central question within the time perception literature is whether timing relies on a …
Death from myocardial infarction and progressive coronary disease is still the number one killer for men and women in the United States and other developed nations. The role of the cardiologist is to efficiently fix the "heart pump" and return the patient to his or her role in s…
Mild to moderate traumatic brain injury (TBI) is associated with increased risk of Post-Traumatic Stress Disorder (PTSD) in returning veterans of the Iraq and Afghanistan wars. Evidence from neuroimaging and neuropsychological studies suggests that PTSD and TBI may share a commo…
This position paper explores information on military background and mental health status of criminal defendants. Focusing on Vietnam, Iraq and Afghanistan veterans, the link between military service, post-traumatic stress disorder and criminal behavior is thoroughly examined. De…
Waterpipe tobacco smoking has become increasingly popular in the past decade, yet no studies examined personality predictors of its use. This study is the first to assess impulsivity as a potential correlate for waterpipe tobacco smoking use and frequency. 43.2% reported ever us…
Stimulus-elicited (phasic) skin conductance responses (SCRs) to indifferent stimuli have often been employed to examine abnormalities in orienting (allocation of attention) in studies of schizophrenia. Most previous studies have examined phasic activity only during habituation p…
Organismic variables appear to modulate various forms of opioid-mediated behaviors. For instance, morphine antinociception is sensitive to gender and aging differences in that its magnitude is greater in male than in female rats, and is lower in older than in younger female rats…
Cardiac patients after an event, such as myocardial infarction (MI), coronary artery bypass graft surgery (CABGs), and percutaneous transluminal coronary angioplasty (PTCA), or/and heart transplant, commonly experience prolonged psychological depression following hospital discha…
This study describes Palestinian refugee women's experience and management of diabetes while living in a refugee camp. The effects of their personal status and health on quality of life are also examined. In-depth interviews were conducted in Arabic by the investigator with 42 P…
Two very different approaches to managing stress have been developed. Relaxation training has documented efficacy with many conditions, and recently, written emotional disclosure has also demonstrated positive health effects. No prior studies have directly compared their efficac…
This dissertation is a biblical and theological study of human physiological phenomena which occurred in connection with manifestations of God's presence. By investigating human physiological phenomena, we are ultimately interested in how God's presence affects the subjects of h…

Two multi-group studies were conducted to investigate flashbulb (FB) memories for the death of the President of Turkey, Turgut Özal. In Study 1, the recollections of two groups of participants (Turks living in Turkey and in North America) were obtained twice, two weeks and seven…
Circadian rhythms in rodents can be phase shifted by activity bouts or light pulses. Syrian hamsters were entrained to a 14:10 full photoperiod (FPP) and were induced to run in the middle of their subjective day. Four of 11 hamsters showed high levels of induced wheel running an…
This thesis will partly compare the approaches of two pioneers in Islamic philosophy to the soul-body problem: the philosophical psychology of Mulla Sadra (Sadr al-Muta'allihin Shirazi 975-1050/1571-1640) and that of Ibn Sina (370-428/980-1037). Our main concern will be with the…
