Attitudes Of College Students Toward People With Disabilities, Doris M. King Jan 2000

Attitudes Of College Students Toward People With Disabilities, Doris M. King

Theses, Dissertations and Capstones

The purpose of this study is to explore the attitudes of college students toward individuals with disabilities. The instrument used was the Attitude Toward Disabled Persons Scale (ATDP), which was adapted to yield two additional scales. The words “mental illness” and “alcoholic” were substituted for “physically disabled”. The test was administered to undergraduate and graduate students in counseling and psychology.

Analysis of Variance was performed. The results showed a significant gender effect with females having more positive attitudes toward individuals with physical disabilities and mental illnesses. Both groups, males and females, had more positive attitudes toward individuals with physical disabilities …


A Holistic Approach To Managing Behavioral Issues With Persons With Mental Retardation In Extended Care Facilities, Darrell Lilly Jan 2000

A Holistic Approach To Managing Behavioral Issues With Persons With Mental Retardation In Extended Care Facilities, Darrell Lilly

Theses, Dissertations and Capstones

Providing long term care for individuals with mental retardation is one of the most difficult issues confronting mental health and extended care facilities. Inappropriate behaviors related to long term institutionalization present an exceptional challenge for those caring for persons with mental retardation. Applied Humanism emphasizes a holistic view of the person. It recognizes that encouragement, responsibility, the right of choice, and an understanding of human potential are important elements for helping mentally retarded persons develop socially appropriate behaviors. This study examined the principles of applied humanism in the management of inappropriate behaviors among mentally retarded persons in an extended care …


The Effects Of Anxiety Management And Study Skills Training On Test Anxiety In College Students, Karen Carter-Harvey Jan 2000

The Effects Of Anxiety Management And Study Skills Training On Test Anxiety In College Students, Karen Carter-Harvey

Theses, Dissertations and Capstones

This study measured the effects of anxiety management and study skills training on test anxiety in college students. Twenty-one college students from two sections of Introductory Sociology were involved in the study. The Test Anxiety Inventory (TAI) and exam scores were used to evaluate the effectiveness of the training. Pre-test, post-test, and delayed post-test measures were obtained. The analysis of variance (ANOVA) indicated no significant difference on TAI scores or exam scores between the control and experimental groups. Recommendations for further research are given.


Regulation Of Contact With Offspring By Domestic Sows: Temporal Patterns And Individual Variation, E. A. Pajor, D. L. Kramer, D. Fraser Jan 2000

Regulation Of Contact With Offspring By Domestic Sows: Temporal Patterns And Individual Variation, E. A. Pajor, D. L. Kramer, D. Fraser

Rearing Behavior Collection

We used a sow-controlled housing system to examine temporal and individual variation in the tendency of sows to associate with young. During a 5-week lactation, 22 sows and litters were housed in a pen where the sow could freely leave and re-enter the piglets' area by stepping over a barrier that the piglets could not cross. Despite this option, the sows remained with the piglets almost constantly during the 1st day after birth. Nineteen sows ('leavers') changed to spending most of their time away from the litter at some point in the lactation. The change was rapid, often within a …


A Preliminary Investigation Of The Construct Of Psychopathic Personality (Psychopathy) In Chimpanzees (Pan Troglodytes), Scott O. Lilienfeld, Jonathan Gershon, Marshall Duke, Lori Marino, Frans B. M. De Waal Dec 1999

A Preliminary Investigation Of The Construct Of Psychopathic Personality (Psychopathy) In Chimpanzees (Pan Troglodytes), Scott O. Lilienfeld, Jonathan Gershon, Marshall Duke, Lori Marino, Frans B. M. De Waal

Sentience Collection

Although the construct of psychopathy has received considerable attention in humans, its relevance to other animals is largely unknown. We developed a measure of psychopathy for use in chimpanzees (Pan troglodytes), the Chimpanzee Psychopathy Measure (CPM), and asked 6 raters to complete this index on 34 chimpanzees. The CPM (a) demonstrated satisfactory interrater reliability and internal consistency; (b) exhibited marginally significant sex differences (males > females); (c) correlated positively with measures of extraversion, agreeableness, and observational ratings of agonism, sexual activity, daring behaviors, teasing, silent bluff displays, and temper tantrums, and negatively with observational ratings of generosity; and (d) demonstrated incremental …


Social Mechanisms Enhance Escape Responses In Shoals Of Rainbowfish, Melanotaenia Duboulayi, Culum Brown, Kevin Warburton Dec 1999

Social Mechanisms Enhance Escape Responses In Shoals Of Rainbowfish, Melanotaenia Duboulayi, Culum Brown, Kevin Warburton

Aquaculture Collection

Shoaling behaviour has been shown to provide many benefits to group members. In this study we examined the ability of fish shoals to escape from a novel trawl apparatus. Fish in shoals of 5 found, and escaped through, a hole in the oncoming trawl more quickly than fish in pairs. Fish in the larger shoals displayed a significant decrease in escape latencies over a series of five trawls, providing clear evidence of net avoidance learning, whereas fish in pairs showed no evidence of learning over successive runs. Observations suggested that more information on the location of the escape route was …


Scale-Model Comprehension By Chimpanzees (Pan Troglodytes), Valerie A. Kuhlmeier, Sarah T. Boysen, Kimberly L. Mukobi Dec 1999

Scale-Model Comprehension By Chimpanzees (Pan Troglodytes), Valerie A. Kuhlmeier, Sarah T. Boysen, Kimberly L. Mukobi

Sentience Collection

The ability of chimpanzees (Pan troglodytes) to recognize the correspondence between a scale model and its real-world referent was examined. In Experiments 1 and 2, an adult female and a young adult male watched as an experimenter hid a miniature model food in 1 of 4 sites in a scale model. Then, the chimpanzees were given the opportunity to find the real food item that had been hidden in the analogous location in the real room. The female performed significantly above chance, whereas the male performed at chance level. Experiments 3 and 4 tested 5 adult and 2 adolescent chimpanzees …


Predicting Flock Vigilance From Simple Passerine Interactions: Modelling With Cellular Automata, David B. Bahr, Marc Bekoff Oct 1999

Predicting Flock Vigilance From Simple Passerine Interactions: Modelling With Cellular Automata, David B. Bahr, Marc Bekoff

Ethology Collection

Vigilance in flocks can be described and modelled as a plausible set of local interactions between neighbouring birds. Each bird in the modelled flock chooses to feed or to scan based solely on whether or not its neighbours are feeding or scanning. This simple model has the ability both to reproduce observations that have not been previously explained and to predict flock behaviours that might be confirmed with future field studies. Examples include simulations showing decreased vigilance with increased flock size (as observed in the field), greater time spent scanning when obstacles such as trees are present (as observed) and …


Asymmetry And Fighting Performance In The Shore Crab Carcinus Maenas, Lynne U. Sneddon, John P. Swaddle Aug 1999

Asymmetry And Fighting Performance In The Shore Crab Carcinus Maenas, Lynne U. Sneddon, John P. Swaddle

Veterinary Science and Medicine Collection

Fluctuating asymmetries (left–right differences in symmetric traits) can be negatively related to fitness parameters in a number of biological systems. Hence, it has been suggested that symmetric individuals should outcompete asymmetric individuals during intraspecific agonistic encounters. However, there is a lack of experimental evidence for such a relationship. We investigated the relationship between trait asymmetry (both directional and fluctuating asymmetry) and the outcome of agonistic encounters among size-matched male shore crabs. Our findings indicate that cheliped (‘weapon claw’) directional asymmetry is not related to the outcome of fights, whereas fluctuating asymmetry in the fifth pereiopod, but not the second pereiopod, …


Overcoming Response Bias Using Symbolic Representations Of Number By Chimpanzees (Pan Troglodytes), Sarah T. Boysen, Kimberly L. Mukobi, Gary G. Berntson Jun 1999

Overcoming Response Bias Using Symbolic Representations Of Number By Chimpanzees (Pan Troglodytes), Sarah T. Boysen, Kimberly L. Mukobi, Gary G. Berntson

Sentience Collection

We previously reported that chimpanzees were unable to optimally select the smaller of two candy arrays in order to receive a larger reward. When Arabic numerals were substituted for the candy arrays, animals who had had prior training with numerical symbols showed an immediate and significant improvement in performance and were able to select reliably the smaller numeric representation in order to obtain a larger reward. Poor performance with candy arrays was interpreted as reflecting a response bias toward the intrinsic incentive and/or perceptual features of the larger array. In contrast, the Arabic numerals represent numerosity symbolically and appear to …


The Effects Of Color Contrast On Performance Of The Wais-R Digit Symbol Subtest, Wendell S. Francke Jan 1999

The Effects Of Color Contrast On Performance Of The Wais-R Digit Symbol Subtest, Wendell S. Francke

Theses, Dissertations and Capstones

Color contrast has been shown to aid in visual search tasks using electronic displays, while the research regarding the usefulness of color contrast in aiding visual search using a paper medium is mixed. The present study questions whether subjects’ performance will improve on a paper task where the search target is in high color contrast when compared with a task where the target color does not differ from the rest of the search field.

Thirty-nine adults with normal vision were administered two forms of the WAIS-R digit symbol subtest, one with low chromatic contrast and one with high chromatic contrast, …


Comparing Aggression Between Young-Adult And General Admission Patients In A State-Inpatient Psychiatric Hospital, Jill Kridle Jan 1999

Comparing Aggression Between Young-Adult And General Admission Patients In A State-Inpatient Psychiatric Hospital, Jill Kridle

Theses, Dissertations and Capstones

Because of the inherent danger surrounding violence, aggression studies are particularly important for those working in a health care setting. A constant variable in aggression studies that poses many risk factors is age. This study examined characteristics of aggressors contained on state psychiatric hospital, located in West Virginia. Included on the unit was the neo-adult program and some general admission patients. The study evaluated all aggressors on the unit between September 1997 and August 1998. Comparisons were made to distinguish any possible differences or similarities between the two groups. The results indicated some differences relating to age of aggressor. Young-adult …


The Effect Of Music On Visuospatial Memory, James L. Mccracken Jan 1999

The Effect Of Music On Visuospatial Memory, James L. Mccracken

Theses, Dissertations and Capstones

Music was utilized in an attempt to enhance visuospatial memory. Twenty-eight individuals, who attended a United Methodist Church in southern West Virginia, were randomly assigned to experimental and control conditions. The experimental group was exposed to new age and classical compositions, counterbalanced for order effects. The new age and classical selections were of similar tempo and complexity. The control group received two relaxation periods, of a comparable length to the music presented to the experimental group. The 7/24 Spatial Recall Test was used to measure visuospatial memory. The measure was administered to each participant immediately after exposure to the music …


Behavioral Interactions And Conflict Among Domestic Dogs, Black-Tailed Prairie Dogs, And People In Boulder, Colorado, Marc Bekoff, Robert W. Ickes Jan 1999

Behavioral Interactions And Conflict Among Domestic Dogs, Black-Tailed Prairie Dogs, And People In Boulder, Colorado, Marc Bekoff, Robert W. Ickes

Ethology Collection

Interactions among domestic dogs (Canis familiaris), black-tailed prairie dogs (Cynomys ludovicianus), and people were studied at Dry Creek, Boulder, Colorado. Our objective was to develop a basic understanding of the nature of dog–prairie dog interactions in this recreational area, because this is an issue that has high visibility and over which there is conflict in Boulder: There are those who want dogs to run free regardless of their impact on the behavior and lives of prairie dogs and those who want to protect prairie dogs and have dogs restrained or go elsewhere. We found that dogs clearly influenced the behavior …


Does The Intermediate Booklet Category Test Detect Neurological Deficits In Adhd Children?, Mindy B. Layne Jan 1999

Does The Intermediate Booklet Category Test Detect Neurological Deficits In Adhd Children?, Mindy B. Layne

Theses, Dissertations and Capstones

The purpose of this study was to evaluate the capability of the Intermediate Booklet Category Test (EBCT) detecting neurological deficits among ADHD children. The study included thirty children between the ages of 9 and 14 years with at least an Average IQ. Fifteen of the children were previously diagnosed with ADHD and the other fifteen children did not have any ADHD diagnosis.


Geographic Variation In Alarm Calls Of Gunnison's Prairie Dogs, C. N. Slobodchikoff, S. H. Ackers, M. Van Ert Dec 1998

Geographic Variation In Alarm Calls Of Gunnison's Prairie Dogs, C. N. Slobodchikoff, S. H. Ackers, M. Van Ert

Communication Skills Collection

Geographic variation in alarm calls of Gunnison's prairie dogs (Cynomys gunnisoni) was analyzed at regional and local scales. Alarm calls in response to a common stimulus (the same human) were recorded at four colonies near Flagstaff, Arizona, and at six sites throughout the southwestern United States. The acoustic structure of calls was analyzed for seven call variables. Regional differences fit the prediction of greater differences with increased geographical separation. Differences between colonies at a local scale were not related to geographical distance, suggesting that local dialects exist within a region. Differences in the level of predation by humans …


Impact Of An Ecological Factor On The Costs Of Resource Acquisition: Fighting And Metabolic Physiology Of Crabs, L. U. Sneddon, F. A. Huntingford, A. C. Taylor Oct 1998

Impact Of An Ecological Factor On The Costs Of Resource Acquisition: Fighting And Metabolic Physiology Of Crabs, L. U. Sneddon, F. A. Huntingford, A. C. Taylor

Ethology Collection

  1. Current game theory models and recent experimental evidence suggests that the strategy an animal adopts in agonistic encounters is determined by individual state. Therefore manipulation of an individual’s state should elicit different behavioural responses. In this paper, mechanisms are examined that underlie state-dependent strategies using Shore Crabs, Carcinus maenas, and how, by altering the environment, behaviour and physiology are affected.
  2. Fights were staged between pairs of male crabs under normoxic and severely hypoxic (< 15 torr) conditions to determine if the metabolic costs of fighting and resource acquisition are affected by water PO2. After fighting, blood and tissue samples from each crab were taken and analysed for metabolites associated with anaerobiosis (L-lactate, glucose and glycogen).
  3. The spectrum …


‘Pleasures’, ‘Pains’ And Animal Welfare: Toward A Natural History Of Affect, D. Fraser, I. J.H. Duncan Jan 1998

‘Pleasures’, ‘Pains’ And Animal Welfare: Toward A Natural History Of Affect, D. Fraser, I. J.H. Duncan

Animal Welfare Collection

In hedonic theories of motivation, 'motivational affective states' (MASs) are typically seen as adaptations which motivate certain types of behaviour, especially in situations where a flexible or learned response is more adaptive than a rigid or reflexive one. MASs can be negative (eg unpleasant feelings of hunger or pain) or positive (eg pleasant feelings associated with eating and playing). Hedonic theories often portray negative and positive MASs as opposite ends of a one-dimensional scale.

We suggest that natural selection has favoured negative and positive affect as separate processes to solve two different types of motivational problems. We propose that negative …


Translocation Effects On The Behavior Of Black-Tailed Prairie Dogs (Cynomys Ludovicianus), John P. Farrar, Karin L. Coleman, Marc Bekoff, Eric Stone Jan 1998

Translocation Effects On The Behavior Of Black-Tailed Prairie Dogs (Cynomys Ludovicianus), John P. Farrar, Karin L. Coleman, Marc Bekoff, Eric Stone

Ethology Collection

We examined the effects of translocation on Black-tailed prairie dog (Cynomys ludovicianus) anti-predator behavior by recording response distances and response times to a human intruder in three colonies containing native, translocated, and combined native and translocated prairie dogs. The translocated prairie dogs barked alarms and concealed themselves at significantly greater intruder distances than mixed or native colonies. However, individuals in different colonies did not differ in the time taken to return to a burrow, to conceal themselves after a human approached the colony, or in the time elapsed after concealment until an animal reappeared. Translocated prairie dogs exhibited nearly twice …


Why It Is Important To Understand Animal Behavior, Joy Mench Jan 1998

Why It Is Important To Understand Animal Behavior, Joy Mench

Anthropomorphism and Anthropocentrism Collection

Although people have long been fascinated by the behavior of animals, the formal discipline of animal behavior--ethology--is actually relatively new, dating to the work of Konrad Lorenz in Austria in the 1930s. Application of ethological principles and methods to the study of animal welfare is an even newer endeavor, of course, and one that has generated a great deal of stimulating discussion and controversy during its short history. In this paper, I provide an overview of the development of behavioral approaches to the study of animal welfare. I then discuss some reasons that behaviors are important to animals and describe …


Farrowing Behaviour And Stillbirth In Two Environments: An Evaluation Of The Restraint-Stillbirth Hypothesis, D. Fraser, P. A. Phillips, B. K. Thompson Dec 1997

Farrowing Behaviour And Stillbirth In Two Environments: An Evaluation Of The Restraint-Stillbirth Hypothesis, D. Fraser, P. A. Phillips, B. K. Thompson

Reproductive Behavior Collection

A total of 59 farrowings were studied in either a conventional, narrow farrowing crate (0.43 m wide) or a much wider alternative design with sides spaced 1.2 m apart at the sow’s standing height but narrowing near the floor to limit the sow’s lying area. Using video recording, we monitored each “birth interval” (i.e. the period between two successive births) and noted the interval’s length, the sow’s posture and postural changes during the interval, and whether the interval ended with a live-born or stillborn piglet. The wide and conventional crates did not differ significantly in median interval between piglets (15.9 …


Weapon Size Versus Body Size As A Predictor Of Winning In Fights Between Shore Crabs, Carcinus Maenas (L.), Lynne U. Sneddon, Felicity A. Huntingford, Alan C. Taylor Oct 1997

Weapon Size Versus Body Size As A Predictor Of Winning In Fights Between Shore Crabs, Carcinus Maenas (L.), Lynne U. Sneddon, Felicity A. Huntingford, Alan C. Taylor

Veterinary Science and Medicine Collection

Relative body size (carapace width) and weapon size (chela length) were used as indicators of resource holding potential (RHP) in the agonistic behaviour of male shore crabs, Carcinus maenas (L.). Weapon size was found to be a more reliable predictor of the outcome of pairwise fights than body size. Crabs with longer chelae than their opponents were more likely to win fights than crabs with relatively larger bodies. Body size had less influence on the outcome of fights. Relative body and weapon size did not influence initiation of contests but did affect the likelihood of winning; however, this was significant …

Vocalizations By Isolated Piglets: A Reliable Indicator Of Piglet Need Directed Towards The Sow, Daniel M. Weary, Stephen Ross, David Fraser Jul 1997

Vocalizations By Isolated Piglets: A Reliable Indicator Of Piglet Need Directed Towards The Sow, Daniel M. Weary, Stephen Ross, David Fraser

Communication Skills Collection

When suckling piglets are isolated from the sow and litter-mates they vocalize a great deal. Sows also call when isolated from their piglets. In one experiment, we found that isolated piglets doubled their call rate in response to playback of sow calls, indicating that piglets are directing calls towards the sow. In a second experiment, we found that variation in the piglet isolation calls related to aspects of the piglet's condition: piglets isolated for 13 min in an enclosure kept at approximately 14°C called more, used higher frequency calls and longer calls, than litter-mates isolated in an enclosure kept at …


The Scientific Validity Of Subjective Concepts In Models Of Animal Welfare, Françoise Wemelsfelder May 1997

The Scientific Validity Of Subjective Concepts In Models Of Animal Welfare, Françoise Wemelsfelder

Animal Welfare Collection

This paper takes a closer look at the subjectivity/objectivity relationship, as it plays a role in the science of animal welfare. It argues that subjective, experiential states in animals such as well-being and suffering are, contrary to what is often assumed, open to empirical observation and scientific assessment. The presumably purely private, inaccessible nature of such states is not an inherent property of these states, but derives from their misguided conception as ‘causal objects’ in mechanistic models of behaviour. This inevitably endows subjective experience with a ‘hidden’ status. However, subjective experience should be approached on its own conceptual grounds, i.e. …


Development Of Piagetian Object Permanence In A Grey Parrot (Psittacus Erithacus), Irene M. Pepperberg, Mark R. Willner, Lauren B. Gravitz Mar 1997

Development Of Piagetian Object Permanence In A Grey Parrot (Psittacus Erithacus), Irene M. Pepperberg, Mark R. Willner, Lauren B. Gravitz

Sentience Collection

The authors evaluated the ontogenetic performance of a grey parrot (Psittacus erithacus) on object permanence tasks designed for human infants. Testing began when the bird was 8 weeks old, prior to fledging and weaning. Because adult grey parrots understand complex invisible displacements (I. M. Pepperberg & F. A. Kozak, 1986), the authors continued weekly testing until the current subject completed all of I. C. Uzgiris and J. Hunt's (1975) Scale 1 tasks. Stage 6 object permanence with respect to these tasks emerged at 22 weeks, after the bird had fledged but before it was completely weaned. Although the parrot progressed …


A Study Of Self-Esteem Comparing Special Education With Regular Education Students During The Middle School Years, Debra A. Davis Jan 1997

A Study Of Self-Esteem Comparing Special Education With Regular Education Students During The Middle School Years, Debra A. Davis

Theses, Dissertations and Capstones

The purpose of this study was to compare differences in levels of self-esteem between special education students and a control group of normal students. One hundred sixty-two fifth- through eighth-grade students from Doddridge County Middle School, West Union, West Virginia, were assessed by teachers using the Self-Esteem Index. The students were initially divided into two groups according to their placement in the regular or the special education programs. There was a total of 81 students in each of the groups. The configuration of each group was as follows: 24 learning-disability students, 14 behavior-disorder students, 16 gifted students, nine speech/language-disorder students, …


The Effects Of Cognitive-Behavioral Therapy On Anxiety Among The Elderly In A Nursing Home Setting, Lawrence David Parker Jan 1997

The Effects Of Cognitive-Behavioral Therapy On Anxiety Among The Elderly In A Nursing Home Setting, Lawrence David Parker

Theses, Dissertations and Capstones

This study evaluated the effects of cognitive-behavioral therapy on the severity of anxiety among the elderly in a nursing home setting. Eighteen adults were involved in the research. The Beck Anxiety Inventory (BDI) was used for a pre-test, post-test, and delayed post-test measures. The results of the t-test indicated a significant difference between the pre-test and the post-test measures in the experimental group. The significant difference was not, however, maintained over time. The results of t-test between the pre-test delayed post-test for the experimental group was non-significant. The results of the study suggested that cognitive-behavioral therapy training did have a …


A Concurrent Validity Study Of The Kaufman Brief Intelligence Test And The Wechsler Adult Intelligence Scale - Revised, Kimberly D. Rayburn Jan 1997

A Concurrent Validity Study Of The Kaufman Brief Intelligence Test And The Wechsler Adult Intelligence Scale - Revised, Kimberly D. Rayburn

Theses, Dissertations and Capstones

The Kaufinan Brief Intelligence Test (K-BIT) as a valid screening instrument for the more comprehensive Wechsler Adult Intelligence Scale-Revised (WAIS-R) was studied. Both assessment instruments were administered to 34 subjects referred to a private psychological practice as part of a requested battery of test. Each test produces a verbal score, nonverbal score and combined verbal and nonverbal score. Results indicate that each section of the K-BIT has a significant correlation to its WAIS-R counterpart. The correlation between the verbal scores, nonverbal scores and the combined scores of the two instruments were .87, .78, and .88, respectively. The K-BIT appears to …


Language-Naive Chimpanzees (Pan Troglodytes) Judge Relations Between Relations In A Conceptual Matching-To-Sample Task, Roger K.R. Thompson, David L. Oden, Sarah T. Boysen Jan 1997

Language-Naive Chimpanzees (Pan Troglodytes) Judge Relations Between Relations In A Conceptual Matching-To-Sample Task, Roger K.R. Thompson, David L. Oden, Sarah T. Boysen

Sentience Collection

Three chimpanzees with a history of conditional and numeric token training spontaneously matched relations between relations under conditions of nondifferential reinforcement. Heretofore, this conceptual ability was demonstrated only in language-trained chimpanzees. The performance levels of the language-naive animals in this study, however, were equivalent to those of a 4th animal—Sarah—whose history included language training and analogical problem solving. There was no evidence that associative factors mediated successful performance in any of the animals. Prior claims of a profound disparity between language-trained and language-naive chimpanzees apparently can be attributed to prior experience with arbitrary tokens consistently associated with abstract relations and …
