As the most robust accessory mineral, both physically and chemically, zircon can preserve valuable geochemical information of the melt that it crystallized from, which makes it an extremely powerful tool to investigate the nature of the first 500 Ma of Earth’s history. Zircon is…

Understanding why conflict persists or comes to a peaceful resolution is a central question in international relations. In these three chapters I examine the micro and macro factors that affect the Israeli-Palestinian conflict—one of the most enduring, and focal conflicts. In th…
The present study tested aspects of restorative environments theoretical frameworks developed by Kaplan and Kaplan (1989) and Ulrich (1983). The frameworks have similar evolutionary assumptions, and both predict that natural environments are relatively high in restorative potent…
This dissertation explores the social impact and cultural meaning of Christian conversion among Dayaks, the indigenous people of East Kalimantan, Indonesia. The findings are based on eighteen months of fieldwork in Samarinda, East Kalimantan as well as archival research conducte…
Cross-language activation among the three languages of trilingual speakers was studied using a cross-language, translation-equivalent priming paradigm in a lexical-decision task. The effects of proficiency level in each language and the relative proficiency levels of the three l…
The simultaneous presentations of independently-established discriminative stimuli can control rates of operant responding higher than rates maintained by the individual stimuli. This “additive-summation” phenomenon has been shown with a variety of different reinforcers (e.g. fo…
The role of assembled phonology in English word recognition has been the focus of a considerable research effort. Yet, the empirical findings regarding the role of assembly exhibit marked contradictions, which are further linked to the properties of the experimental method. This…
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 …
The nature of learning in backward masking was investigated in a series of experiments. Five experiments were conducted to probe various aspects of learning in backward masking, including retention over time without practice, transfer of learning across different SOAs, and trans…
Five experiments were concerned with the occurrence of one behavior. i.e., head-banging, under conditions of reinforcement, extinction, limited reinforcement, and choice when an alternative behavior, i.e., key-pecking, was reinforced under a variety of reinforcement schedules. T…
Does the development of sensory processing effect preferential looking behavior? Three experiments were performed, each with a sample of 13 three- and four-month-old infants to provide insight into this question. In addition, a fourth experiment was conducted to determine if a c…
Circadian rhythms in Syrian hamsters can be phase shifted by behavioural arousal during the usual rest phase of the circadian rest-activity cycle. Phase shifts can be greatly potentiated by prior exposure to constant light for 2 cycles. This could reflect nonphotic input pathway…
This dissertation presents research on functional and neural mechanisms of cognition-emotion interaction in incentive learning (preference formation) and related decision making (preference expression) in three chapters. A novel reward-based preference formation and expression t…
Day and night are often simulated for nocturnal rodents in the laboratory with 24 h lighting regimes alternating between moderate indoor light levels and complete darkness. Sometimes, complete darkness is replaced by dim illumination to aid human vision, with the assumption that…
A measure of Narcissistic Group Identity was developed and tested in a cross-sectional pilot study of 319 university students. Analyses revealed that Narcissistic Group Identity predicted more negative attitudes toward Arab immigrants, compared to Asian, Latino, and European imm…
This dissertation examines the reference frames used in the representation of location of tactile stimuli, using data from neurologically intact participants in experiments that use a spatial interference effect, and from brain-damaged individuals with tactile perception deficit…
This thesis explores the effects of discourse context, specifically whether a referent is discourse-given or discourse-new, on the online processing of the dative alternation and the active/passive alternation. Previous research provides support that the discourse status of a re…
In this thesis different data were analyzed, including behavioural performance (speed and accuracy), fMRI brain activation, and modelling simulation, to investigate the underlying processes in perceptual and symbolic, masked and unmasked magnitude priming. The perceptual stimuli…
In Syrian hamsters, circadian rhythms can be phase shifted by light at night or by behavioural arousal during the day (usual sleep period). Previous work in this lab has defined arousal procedures that have differential clock resetting effects; arousal stimulated by running in a…
