The Effects Of Perceived Predation Threat On Stress Response And Memory In Birds, Chlöe S. N. Carter
The Effects Of Perceived Predation Threat On Stress Response And Memory In Birds, Chlöe S. N. Carter
Electronic Thesis and Dissertation Repository
This study examined how perception of predator cues, across three sensory modalities, affects physiology and behaviour of songbirds. I hypothesized that the perception of predator threat would elicit physiological and behavioural responses in both acute and chronic exposure conditions. My first study examined the responses of wild-caught black-capped chickadees (Poecile atricapillus) and house sparrows (Passer domesticus), as well as lab-bred zebra finches (Taeniopygia guttata), to acute predation cue exposure by coding video recorded behaviour and corticosterone analysis. My second study examined changes in black-capped chickadees’ foraging behaviour and memory retention after chronic exposure to …

Synaptic Correlates For Stress Sensitization, Julia Kj Sunstrum
Electronic Thesis and Dissertation Repository
The stress response is essential for survival, but it can be detrimental when persistently activated during chronic stress. Therefore, the magnitude of the stress response must be finely-tuned in order to be adaptive. Indeed, an animal’s stress response system normally undergoes habituation that decreases responses to a repeated, familiar stressor. Importantly, the same animal still responds normally, or even becomes sensitized, to an unfamiliar (novel) stressor. This indicates that chronic stress simultaneously induces two opposing types of plasticity, one that underlies habituated responses and another that drives sensitized responses. The activation of the hypothalamic-pituitary-adrenal (HPA) axis — a hallmark of …
The Effects Of Aromatherapy On Stress In A University Population, Theresa L. Flagler
The Effects Of Aromatherapy On Stress In A University Population, Theresa L. Flagler
Undergraduate Honours Theses
The purpose of the present study was to determine whether aromatherapy has an effect on stress responses in a population of undergraduate university students at a liberal arts college. To do this, participants were brought to a laboratory room and asked to complete a task designed to increase feelings of stress and anxiety by having participants perform a song in front of the researcher. During this, either water vapor infused with a small quantity of lavender oil or unadulterated water vapour was diffusing into the room. To measure stress, participants wore a heart rate monitor throughout the duration of the …
Understanding Burnout In Undergraduate Students: The Role Of Social Media, Paige Walker
Understanding Burnout In Undergraduate Students: The Role Of Social Media, Paige Walker
Brescia Psychology Undergraduate Honours Theses
This study investigated different factors relating to undergraduate burnout and whether social media could act as a protective factor. The study group was comprised of 66 female undergraduate psychology students at Brescia University College. Participants completed one questionnaire with seven subscales which measured the following variables: subjective well-being, student subjective well-being, personality traits, social support, stress, online support, and burnout. The participants were divided into three groups based on their burnout scores. The results of the ANOVA indicated that there were significant differences between the three burnout groups on: subjective well-being, student subjective well-being, conscientiousness, extraversion, openness, social support, and …
Anxiety And Stress In First Year University Students, Kimberly Mccready
Anxiety And Stress In First Year University Students, Kimberly Mccready
Brescia Psychology Undergraduate Honours Theses
The purpose of the study was two-fold: to confirm the finding that anxiety and stress increases as exams draw near, and to provide evidence that smokers will have greater increases in anxiety and stress than non-smokers, as well as increased smoking urges as exam draws near, to deal with the related increase in anxiety and stress. To investigate this, participants were asked to fill out the DASS-21 at three-time points (4 weeks, 2.5 weeks, and 1 week) before the Psychology 1000 midterm examination. Smoking urges of smokers was also to be assessed, however, due to lack of smoking participants, no …
