Temperature And Pain Changes Resulting From Post Surgical (Arthroscopy) Application Of Cold Packs, Caroline L. Creager Dec 1990

Temperature And Pain Changes Resulting From Post Surgical (Arthroscopy) Application Of Cold Packs, Caroline L. Creager

All-Inclusive List of Electronic Theses and Dissertations

Post-surgical cold applications are beneficial to orthopedic surgery patients. However, their use is limited because of the difficulty in maintaining a constant temperature, increased need for attention, and unwanted leaks or condensation from ice bags. Twenty-one arthroscopic surgery patients were divided into three groups: a Dura*Kold cold pack group, an Aircast Cryo/cuff compression dressing group, and a control group. Six dependent variables were examined: subjective pain ratings three and 48 hours after surgery, a subjective rating of functional activity 48 hours after surgery, skin temperature for three hours after surgery, and pain medication consumed during three hours and 48 hours …


A Comparison Of Circadian Rhythms In Day And Night Shift Workers, Mary Lee Blood Oct 1990

A Comparison Of Circadian Rhythms In Day And Night Shift Workers, Mary Lee Blood

Dissertations and Theses

The present study examined whether and to what extent physiological rhythms of long-term night workers become adapted to their unconventionally scheduled hours of work and sleep and how the degree of adaptation would be reflected in ratings of sleep quality, mood, anxiety, energy and satisfaction.


Inferences About Guessing And Knowing By Chimpanzees (Pan Troglodytes), Daniel J. Povinelli, Kurt E. Nelson, Sarah T. Boysen Sep 1990

Inferences About Guessing And Knowing By Chimpanzees (Pan Troglodytes), Daniel J. Povinelli, Kurt E. Nelson, Sarah T. Boysen

Sentience Collection

The visual perspective-taking ability of 4 chimpanzees (Pan troglodytes) was investigated. The subjects chose between information about the location of hidden food provided by 2 experimenters who randomly alternated between two roles (the guesser and the knower). The knower baited 1 of 4 obscured cups so that the subjects could watch the process but could not see which of the cups contained the reward. The guesser waited outside the room until the food was hidden. Finally, the knower pointed to the correct cup while the guesser pointed to an incorrect one. The chimpanzees quickly learned to respond to the knower. …


Vocal Recognition Of Pups By Mother Mexican Free-Tailed Bats, Tadarida Brasiliensis Mexicana, Jonathan P. Balcombe May 1990

Vocal Recognition Of Pups By Mother Mexican Free-Tailed Bats, Tadarida Brasiliensis Mexicana, Jonathan P. Balcombe

Sentience Collection

The ability of Mexican free-tailed bat mothers and pups to recognize vocalizations of their presumptive kin (pup isolation calls and mother echolocation calls, respectively) was tested using playbacks of recorded calls. Captive individuals were presented with calls of two bats, one presumptive kin and the other a stranger, from opposite sides of a circular wire arena. Response was determined by amount of time spent on each side of the arena, time spent in contact with a cloth bat model in front of each speaker, and number of separate contacts with each model. For the latter two measures, mothers showed a …

Evidence For Common Coding Of Temporal And Nontemporal Information In Pigeons, Stephen Bridson Jan 1990

Evidence For Common Coding Of Temporal And Nontemporal Information In Pigeons, Stephen Bridson

Theses and Dissertations (Comprehensive)

Two experiments found evidence that pigeons commonly code temporal and visual samples that are associated with the same comparisons in many-to-one matching. In Experiment 1, pigeons were trained to match temporal (2-sec and 8-sec keylight durations) and color (red and green) samples to line tilt comparisons (vertical and horizontal). Similar rates of forgetting were found for all samples. Furthermore, retention of sample information appeared more similar for samples which shared common comparisons than those that did not. In Experiment 2, pigeons learned new comparison (circle and triangle) associations with either temporal or visual samples from Experiment 1. When tested on …


The Level And Determinants Of Burnout Of Mormon Mothers In A Utah Suburban Town, Christina Mordock Jan 1990

The Level And Determinants Of Burnout Of Mormon Mothers In A Utah Suburban Town, Christina Mordock

Theses and Dissertations

The purpose of this study was to examine burnout in Mormon mothers in a suburban Utah town. Specifically the amount and some determinants of burnout among these Mormon women was studied. A random sample of 266 Mormon mothers completed a questionnaire and a modified version of the Maslach Burnout Inventory (MBI) which consisted of three subscales, (Emotional Exhaustion, Depersonalization, and Personal Accomplishment), and two categories in each subscale (Frequency and Intensity). The subjects scored in the moderately burned out category in each subscale. Significant relationships were found between the amount of burnout and the following: the age of the mother, …


Nutritive And Nonnutritive Sucking And The Temporal Organization Of The Suckling Behavior Of Domestic Piglets, Jeffrey Rushen, David Fraser Dec 1989

Nutritive And Nonnutritive Sucking And The Temporal Organization Of The Suckling Behavior Of Domestic Piglets, Jeffrey Rushen, David Fraser

Feeding Behavior Collection

Detailed video recordings of the suckling behavior of one piglet from each of four litters were analyzed to determine how the components of piglet suckling behavior are organized in relation to the time of milk ejection and the temporal pattern of grunting by the sow. Early in the suckling episode, most piglets massaged the udder with their snouts, and then changed gradually to sucking the teats with slow mouth movements (1-2/sec). The piglets then had a distinct phase of sucking with rapid mouth movements (4-5/sec) which began suddenly and lasted about 5 to 15 sec. The weight gains of piglets …


Numerical Competence In A Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson Mar 1989

Numerical Competence In A Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson

Sentience Collection

A chimpanzee (Pan troglodytes), trained to count foods and objects by using Arabic numbers, demonstrated the ability to sum arrays of 0-4 food items placed in 2 of 3 possible sites. To address representational use of numbers, we next baited sites with Arabic numbers as stimuli. In both cases performance was significantly above chance from the first sessions, which suggests that without explicit training in combining arrays, the animal was able to select the correct arithmetic sum for arrays of foods or Arabic numbers under novel test conditions. These findings demonstrate that counting strategies and the representational use of numbers …


Non-Breeder Asymmetry In Florida Scrub Jays, Jonathan P. Balcombe Mar 1989

Non-Breeder Asymmetry In Florida Scrub Jays, Jonathan P. Balcombe

Ethology Collection

The data of Woolfenden and Fitzpatrick (1984) show a statistically significant asymmetry in the sex ratio of non-breeders when one of the breeders is not the non-breeder's parent. 1 propose that the asymmetry is attributable to a combination of two factors acting on non-breeders: the value of inheriting a territory, and incest avoidance. Although natal territories are only occasionally inherited by non-breeders, and then apparently only by males, the rate of inheritance is significantly higher for parent/step-parent breeders (n = 6) than when both breeders are the non-breeder's parents (n = 1). An alternative hypothesis, that step-parents determine the non-breeder …


Effects Of Age On Motor Preparation And Restructuring, Paul Amrhein, Noreen Goggin, George Stelmach Mar 1989

Effects Of Age On Motor Preparation And Restructuring, Paul Amrhein, Noreen Goggin, George Stelmach

Department of Psychology Faculty Scholarship and Creative Works

Age-related decrements in motor plan restructuring were investigated. In this experiment, older and younger adults performed a discrete aiming task that involved responses that were precued and responses that were modified at the time of an imperative signal. On 75% of the trials, the precue specified the response-stimulus (valid trials) with respect to the movement parameters of the arm (left or right) and direction (toward or away). On the remaining 25% of the trials, the response-stimulus was different from the precue (invalid trials) in that the subject was required to modify a planned movement by changing the arm to be …

Conspecific Recognition In The Chimpanzee (Pan Troglodytes): Cardiac Responses To Significant Others, Sarah T. Boysen, Gary G. Berntson Jan 1989

Conspecific Recognition In The Chimpanzee (Pan Troglodytes): Cardiac Responses To Significant Others, Sarah T. Boysen, Gary G. Berntson

Sentience Collection

The ability of a chimpanzee (Pan troglodytes) to recognize photographs of conspecifics was evaluated with heart-rate measures. Heart rate was recorded before, during, and after viewing photographs of an aggressive chimpanzee, a friendly companion animal, and an unfamiliar chimpanzee. The subject displayed a differential pattern of heart-rate response to the stimulus animals, without prior experience with the photographs. Responses to the aggressive animal were acceleratory, which suggests a defensive response. Respiratory sinus arrhythmia suggested that this response was associated with sympathetic activation. In contrast, responses to the familiar animal were minimal, whereas cardiac deceleration was observed in response to the …


Comprehension Of "Absence" By An African Grey Parrot: Learning With Respect To Questions Of Same/Different, Irene M. Pepperberg Nov 1988

Comprehension Of "Absence" By An African Grey Parrot: Learning With Respect To Questions Of Same/Different, Irene M. Pepperberg

Sentience Collection

An African Grey parrot, Alex, learned to report on the absence or presence of similarity and difference between two objects. Alex was shown pairs of objects that were (a) totally dissimilar, (b) identical, or (c) similar or different with respect to one of three attributes (color, shape, or material). In the first two cases, he responded to the respective queries of "What's same?" or "What's different?" with the vocalization "none," and in the third case he responded with the appropriate category label ("color," "shape," or "mah-mah" [matter]). His accuracy was 80.9% to 83.9% for pairs of familiar objects not used …


Effects Of Graded And Steady Exercise And Self-Confidence On Stress, Kristine M. Clarke May 1988

Effects Of Graded And Steady Exercise And Self-Confidence On Stress, Kristine M. Clarke

Dissertations and Theses

This study examined the effects of steady, graded, and no exercise on stress reduction, and the effects of self-confidence on stress reduction through exercise. Seventy-two male and female volunteers from the Portland area, ranging in age from 19-49 years, served as subjects. Subjects completed pre and post measures of the Tennessee Self-Concept Scale and the state portion of the Spielberger State-Trait Anxiety Inventory. Subjects were divided into two experimental and one control group matched according to age and exercise history. The control group kept its exercise at a minimum for eight weeks. Exercise programs for the two experimental groups consisted …


Spatial Memory In Pigeons On A Four-Arm Radial Maze, Robert H.I. Dale Mar 1988

Spatial Memory In Pigeons On A Four-Arm Radial Maze, Robert H.I. Dale

Scholarship and Professional Work - LAS

Pigeon spatial memory was examined using a four-arm radial maze. The maze had four arms, spaced at 90° intervals, extending radially from a central choice area. Subjects were forced into three arms, then permitted two choices to enter the remaining ann. Five subjects chose accurately (90% correct) with delays of 5 min or less, their choices depended on extramaze cues, and the food in the target arm provided no essential cues. After an incorrect first choice, subjects' second choices were more accurate than chance. These data suggest that, while spatial memory has many similar characteristics in rats and pigeons, pigeon …


Hiv Antibody Testing: Performance And Counseling Issues, Michael Gross Jan 1988

Hiv Antibody Testing: Performance And Counseling Issues, Michael Gross

New England Journal of Public Policy

This article assesses the performance of currently used tests for exposure to human immunodeficiency virus (HIV), the infectious agent associated with acquired immunodeficiency syndrome (AIDS); suggests, in view of that information, guidelines for counseling people seeking HIV antibody testing; and evaluates the claim that because antibody test results will effect behavior change in those who are infected, all members of high-risk groups should be tested.

HIV testing is likely to yield a high proportion of false-positive results in low-risk populations and infants born to infected mothers. A negative result may not establish freedom from infection in high-risk groups or the …


Understanding The Psychological Impact Of Aids: The Other Epidemic, Marshall Forstein Jan 1988

Understanding The Psychological Impact Of Aids: The Other Epidemic, Marshall Forstein

New England Journal of Public Policy

HIV has created two epidemics, one of disease, the other the consequence of the psychological response to that disease. Thus far, behavioral change is the only effective means of interrupting the transmission of HIV. The underlying psychological dimensions of the societal and individual responses to AIDS are discussed, with suggestions for how both rational thinking and irrational fears and anxiety contribute to the development of public policy. Examples are given of how short-term solutions to reduce anxiety may actually create long-term problems, potentially increasing the risk of transmission of HIV. Specific psychological mechanisms that contribute to the epidemic of fear …


Mineral-Deficient Diets And The Pig’S Attraction To Blood: Implications For Tail-Biting, David Fraser Dec 1987

Mineral-Deficient Diets And The Pig’S Attraction To Blood: Implications For Tail-Biting, David Fraser

Abnormal Behavior Collection

In two experiments, individually penned growing pigs were exposed daily to two "tail models” (lengths of cotton cord about the size of a pig's tail), one of which had been impregnated with pigs' blood. When fed a balanced "control" diet, the pigs chewed significantly more on the blood-covered model than on the plain one, but with Iarge individual differences between animals. Four weeks of receiving a diet lacking all mineral supplements (iodized salt, dicalcium phosphate, limestone, iron, zinc, manganese, copper, and selenium) caused a pronounced increase in chewing the blood-covered model, and 4 wk of recovery on the control diet …


Similarities Between Human And Animal Spatial Memory: Item And Order Information, Robert H.I. Dale Sep 1987

Similarities Between Human And Animal Spatial Memory: Item And Order Information, Robert H.I. Dale

Scholarship and Professional Work - LAS

Human subjects, sitting at the center of a circle of eight lights, were tested on analogues of radial-maze item-recognition (Roberts & Smythe, 1979) and order-recognition (Kesner & Novak, 1982) tasks. Subjects in the item-recognition condition saw a list of seven lights, and then the nonlist (eighth) light was tested against the first, fourth, or seventh light from the list. The sub- jects were required to point toward the non list light. Subjects in the order-recognition condition saw a series of eight lights, followed by a test of the first and second, fourth and fifth, or seventh and eighth serial positions. …


Task Load, Stimulus Encodability, Test Latency, And Processing Efficiency Effects On The Visual Recognition Memory Of The Chronic Neuropsychologically Impaired, Thomas W. C. Blash Aug 1987

Task Load, Stimulus Encodability, Test Latency, And Processing Efficiency Effects On The Visual Recognition Memory Of The Chronic Neuropsychologically Impaired, Thomas W. C. Blash

All-Inclusive List of Electronic Theses and Dissertations

Psychologists assessing the visual recognition memory (VRM) of neuropsychologically compromised clients with the dual diagnosis of cognitive impairment and emotional sequelae confront two problems, including the dearth of studies dealing with the dually diagnosed (Menolascino, 1984) and inconsistent findings from past research on the effects of cerebral compromise on visual memory (Boller & DeRenzi, 1967; Cremonini, DeRenzi, & Faglioni, 1980; DeRenzi & Spinnler, 1966; DeRenzi, Faglioni, & Villa, 1977; Gouvier, 1983; Kimura, 1963). This study examines the effects of task load (number of stimuli), stimulus encodability, test latency, and cognitive processing efficiency on a group of dually diagnosed individuals who …


An Analysis Of The Effects Of A Low Glycemic Diet On The Antisocial Behavior Of Juvenile Offenders, James Edward Longhurst Aug 1987

An Analysis Of The Effects Of A Low Glycemic Diet On The Antisocial Behavior Of Juvenile Offenders, James Edward Longhurst

Dissertations

The objective of this study was to determine if a low glycemic diet contributes to a reduction in the incidence of antisocial behavior among male juvenile offenders.

One hundred forty juvenile offenders at a residential treatment center were randomly divided into treatment and nontreatment groups. The treatment group ate from a diet which contained foods low in glycemic characteristics. There was no dietary alteration for the control group.

Three instruments were used to measure differences between groups in antisocial behavior following a 5-week experimental period. These instruments include: (1) the Unusual Incident Report--a systematic and objective observer report form, (2) …


Attraction To Blood As A Factor In Tail-Biting By Pigs, David Fraser Apr 1987

Attraction To Blood As A Factor In Tail-Biting By Pigs, David Fraser

Abnormal Behavior Collection

Canvas models, about the size of a pig's tail, were impregnated with pigs' blood or left plain, and were presented to pigs for 12 days in a 2-choice preference test. The pigs showed large, consistent, individual differences in response: some pigs chewed the models continuously while others chewed only slightly; some chewed much more on the blood-covered model, while others showed no preference. On average, the pigs chewed considerably more on the blood-covered model than on the plain one. In a second experiment, pigs presented with a choice test involving a blood-covered and a plain model showed a significant increase …


Sensory Modulation Of Juvenile Play In Rats, Stephen M. Siviy, Jaak Panksepp Jan 1987

Sensory Modulation Of Juvenile Play In Rats, Stephen M. Siviy, Jaak Panksepp

Psychology Faculty Publications

A series of experiments was conducted to determine the extent to which somatosensory stimulation is necessary for the elaboration of juvenile play in rats. Anesthetization of the dorsal body surface of juvenile rats with xylocaine reduced the frequency of pinning, an indicator variable for play, by 35% to 70%, while motivation to play, measured by dorsal contacts, an index of play solicitation, remained largely intact. These data suggest that dorsal body surface anesthetization impairs the ability of juvenile rats to perceive and/or respond to playful gestures. When untreated animals were paired with xylocaine-treated animals, the xylocaine-treated animals consistently pinned the …


Assessment Of Influence That The Church Of Jesus Christ Of Latter-Day Saints Has On Exercise Habit Of Members Living In Utah County, Gary L. Preston Jan 1987

Assessment Of Influence That The Church Of Jesus Christ Of Latter-Day Saints Has On Exercise Habit Of Members Living In Utah County, Gary L. Preston

Theses and Dissertations

This study identified and analyzed the influence the Church of Jesus Christ of Latter-day Saints had on the decision of 309 respondents to exercise. The data obtained from the questionaires were analyzed using chi-square to compare males and females. Within the limitations of this study, the following conclusions were justified: women were more influenced by the LDS Church to exercise than men; LDS males and females exercised more than average American adults; walking, jogging, and aerobic dance were the most popular choices of LDS exercisers; and, there is a need to improve the awareness of LDS members concerning the Physical …


Cardiac Correlates Of Individual Recognition In The Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson Sep 1986

Cardiac Correlates Of Individual Recognition In The Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson

Sentience Collection

The ability of a chimpanzee to recognize individuals depicted in photographs was evaluated through the use of heart rate measures. Heart rate was recorded before and during photographic projections of human caregivers, familiar individuals, strangers, and blank control slides. In the absence of explicit training or reinforcement, the chimpanzee displayed a differential pattern of heart rate response to the stimulus categories. Although heart rate responses to all stimuli were predominantly deceleratory, the photographs of caregivers yielded consistently larger responses than other stimuli. Results indicate that the chimpanzee is able to recognize individual humans from novel photographic representations and that heart …


The Effects Of Recreation Specialization And Motivations On The Environmental Setting Preferences Of Backcountry Hikers, Randy J. Virden May 1986

The Effects Of Recreation Specialization And Motivations On The Environmental Setting Preferences Of Backcountry Hikers, Randy J. Virden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study explored how recreation specialization and different types of motivations were related to environmental settings preferred by backcountry hikers. A questionnaire was developed that measured the level of hiking specialization, desired psychological outcomes, and preferred environmental setting attributes. Questionnaires were mailed to 619 backcountry hikers from three Intermountain West hiking areas; a response rate of 68 percent was attained.

Results of the study revealed significant associations between the level of hiking specialization and the psychological states desired by backcountry hikers. In general, increased hiking specialization served to increase the importance of specific psychological outcomes such as autonomy, exercise, achievement …


Variations In Radial Maze Performance Under Different Levels Of Food And Water Deprivation, Robert H.I. Dale, William A. Roberts Mar 1986

Variations In Radial Maze Performance Under Different Levels Of Food And Water Deprivation, Robert H.I. Dale, William A. Roberts

Scholarship and Professional Work - LAS

Four groups of rats were tested on an eight-arm radial maze under a free-choice procedure. The subjects were maintained at either 80% or 100% of their preexperimental free-feeding weights through restricted access to either food or water. Water-deprived subjects received water in the maze; food-deprived subjects received food. Water-deprived subjects learned the task faster than food-deprived subjects. The four groups developed different response patterns. These were measured by the mean transition size, the average angular distance (in 45° units) between consecutively chosen arms. Rats foraging for food and water developed different search strategies, with water-deprived subjects exhibiting lower mean transition …


Effects Of Early Experience Upon Adaptiveness Of Horses, J. C. Heird, R. W. Bell, S. G. Brazier Jan 1986

Effects Of Early Experience Upon Adaptiveness Of Horses, J. C. Heird, R. W. Bell, S. G. Brazier

Equines Collection

Experimentation with laboratory animals, encompassing the range of usual species (mice, rats, cats, clogs, and primates), has conclusively demonstrated that handling by humans during early life facilitates subsequent development in terms of health and viability, reduced emotional reactivity, more adaptive responses to a variety of stressors (both biological and behavioral adaptations), and increased ability to adapt to changing circumstances as exemplified by increased ability to learn and solve problems (seeM. Bornstein 1985, for recent review).

Two studies (described below) (Heircl et a!. 1981; Whitaker 1982) conducted at Texas Tech University (TTU) have extended these findings regarding the beneficial effects of …


Social Ecology And Behavior Of Coyotes, Marc Bekoff, Michael C. Wells Jan 1986

Social Ecology And Behavior Of Coyotes, Marc Bekoff, Michael C. Wells

Ethology Collection

Behavioral patterns are subject to natural selection and behavior like any other attributes of an animal, which contributes to individual survival. The chapter summarizes a long-term study of coyotes that was conducted in the Grand Teton National Park, in the northwest comer of Wyoming. There is remarkable agreement in the results stemming from a limited number of field projects concerned with the social behavior and behavioral ecology of coyotes, and some general principles concerning social ecology, scent marking, predatory behavior, time budgeting, and reproductive and care-giving patterns can be developed that are applicable not only to coyotes but to many …
