Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall

All Master's Theses

This study aimed to establish preliminary health and behavioral data, as well as understand group variation for a large population of Macaca fascicularis individuals within an anthropogenically altered monkey forest. A parasitic analysis of 40 mother and infant individuals showed that M. fascicularis carried 13 different parasitic taxa, and that there was parasitic variation between groups. Body condition scores were determined using a newly created and adapted body condition scale from 146 sampled mother macaques. Body condition scores were significantly different between groups, specifically the pond group when compared to the three other groups. Mother-infant behavioral differences were seen between …

The Effects Of Therapy Balls On In-Seat And On-Task Behavior In Young Children, Ariel Ching

All Master's Theses

This study utilized an alternating treatment design to study the effects of therapy balls, chairs, and the element of choice on the in-seat and on-task behaviors of three, preschool-aged children. Participants were between 4 and 5 years old, typically developing, and were selected based on their ability to make a choice between two different stimuli. This study was conducted at a table, with the participant engaging in a fine-motor activity that they had shown preference to, based on a paired-stimulus preference assessment (Play-Doh, coloring, magnetic blocks, etc.). It was hypothesized that the participants would show higher rates of in-seat and …

Use Of A Two-Action Paradigm Apparatus With Captive Lemurs: Insights Into Social Learning, Carly Batist

All Master's Theses

Lemurs have been understudied in cognitive research despite possessing a unique phylogenetic position as the lineage linking primates to other mammals. I used a two-action paradigm apparatus to test social learning abilities in seven lemur species at the Duke Lemur Center. There were three groups: push (had model previously taught to push), pull (had model previously taught to pull), and control (no model). I conducted experimental trials to determine if lemurs in push/pull groups learned faster and more efficiently from the model than lemurs in control groups who lacked a model to observe. I found evidence of social facilitation in …

Mother-Infant Interactions In A Free-Ranging Population Of Pigtail Macaques (Macaca Nemestrina), Emily Dura

All Master's Theses

The Southern pigtail macaque (Macaca nemestrina) is an understudied species in the Cercopithecidae family distributed in Southeast Asia. In this field study, I focused on interactions of Southern pigtail macaques to better understand mother-infant relationships. I observed five to six mother-infant dyads from April 2016 to September 2016 in the Segari Melintang Forest Reserve, Perak, Peninsular Malaysia. I used focal sampling methods to score mother and infant behaviors from two ethograms. I hypothesized that as infant age increased, mother and infant behaviors seen to be important in pigtail macaque mother-infant captive studies, would change over time. As infant …

Chemical And Behavioral Ecology Of The Coastal Giant Salamander (Dicamptodon Tenebrosus), David Reavill

All Master's Theses

Intraspecific interactions are an important factor in shaping the population structure of terrestrial salamanders. Both physical interactions and scent-marking are vital components to the establishment of territories and influence dispersion of individuals. However, little is known about the terrestrial interactions of many salamander species, particularly that of the Coastal Giant Salamander (Dicamptodon tenebrosus). In this study, I observed the first evidence for the use chemical cues by terrestrial D. tenerosus in regards to shelter selection. I also observed the first accounts of agonistic and display behavior of terrestrial D. tenebrosus. These results suggest that terrestrial D. tenebrosus …

Behavioral Response To Uvb Differs In Subalpine Populations Of Daphnia Melanica, Amanda Tompkins

All Master's Theses

Daphnia are a genus of freshwater zooplankton that inhabit ponds and lakes. They are commonly used as a model organism because they can reproduce clonally and are considered a foundation species in pond ecosystems. Daphnia melanica that inhabit the subalpine ponds of the Olympic National Park are exposed to high levels of ultraviolet radiation (UVR). UVR causes DNA damage that can be detrimental to the organism if not fixed. One way to avoid these harmful rays is to migrate to protected areas. In my study, I looked at two behaviors in D. melanica: diel vertical migration (DVM), which involves …

A Punishment-Free, Toilet-Training Protocol For Children With Developmental Disabilities, Chelsea Lynn Pearsall

All Master's Theses

The present investigation adapted a behaviorally-based toilet-training protocol for use with two male children with developmental disabilities. Positive practice and verbal reprimands were eliminated, and reinforcement, scheduled sits, and a urine alarm were utilized. Data were collected on the number of intoilet urinations, urinary accidents, and self-initiations. Results show that both participants exhibited significant improvement in their toileting skills and met the final success criteria rapidly. These results were maintained through follow-up. Implications for the elimination of punishment procedures in future toilet training protocols are discussed.

Chimpanzee (Pan Troglodytes) Responses To Visitors Using Chimpanzee-Friendly Behaviors, Daniella Bismanovsky

All Master's Theses

Many studies suggest that zoo visitors are a cause of stress among animals; among primates, visitor presence can lead to an increase in aggressive displays, time spent non-visible to the public, and a decrease in overall activity. This study tested the effectiveness of using species-specific behaviors among a group of captive chimpanzees. There were 2 conditions: a control, and an experimental condition in which visitors were asked to adopt a stooped posture or lean on the railing, and show a chimpanzee play face. The visitors stooped their posture, sat, and leaned on the railing significantly more in the experimental condition …

Introversion, Extraversion, And Humor, Tanna Marlane Boucher

All Master's Theses

The differences in behavioral expression of humor for introverts and extroverts was investigated, as well as the behavioral expression of humor and humor ratings of video clips containing sound versus those with no sound. Subjects were videotaped as they watched humorous clips in a room alone. The results indicated that there was no significant difference between introverts and extroverts in terms of their behavioral expression of humor. These findings are consistent with the literature on social aspects of humor in that people tend to express more humor in social groups than when alone. However, subjects did show significantly more behavioral …

Operantly Conditioning A College Student's Study Behaviors, Norman L. Culbertson

All Master's Theses

A 20 year old, male, sophomore college student, who was considered an underachiever, was confined to a laboratory study room for a specified number of observed hours during a period of three weeks. An attempt was made to operantly condition increased study behaviors by the E's control of study break reinforcers. The experiment consisted of three phases, conditioning, reversal, and reconditioning. Statistical results showed that when reinforced in this manner for study behaviors, the S significantly increased his amount of study time and number of pages read. It was concluded that (1) operant conditioning procedures could be used successfully to …

State-Dependent Learning As A Function Of The Temporal Relationship Between Noncontingent Footshock And Electroconvulsive Shock, T. Scott Shutt

All Master's Theses

Rats were given a noncontingent footshock followed at various intervals by electroconvulsive shock. Twentyfour hours later they were trained on a non-shock passive avoidance task and tested for retention 72 hours later. When the interval between NCFS and ECS was short the animals showed an amnesia which reduced as the interval was lengthened. An interval of .5 seconds produced the most pronounced amnesia and intervals greater than 10 seconds produced virtually no amnesia. The results were consistent with a state dependent retrieval failure hypothesis.

Duration Of State-Dependent Learning Induced By Ncfs-Ecs, Larry Wayne Morris

All Master's Theses

This paper investigated the course of the state-dependent function induced by NCFS-ECS at 24 hr. time intervals, beginning at 24 or 48 hrs. after NCFS-ECS treatment and terminating at 120 hrs. Results of both experiments indicate a state-dependent effect lasting up to 72 hrs., was absent at the 96 hr. retention test but, apparently returned by the 120 hr. retention test. Recommendations included investigation of fixed time intervals after the 120 hr. retention test.

The Relationship Of Dogmatism And Internal-External Control To Psychological Reactance, Edward J. Schau

All Master's Theses

One hundred ninety-two Introductory Psychology students volunteered for credit to complete the Rokeach Dogmatism Scale and the Rotter I/E Scale. The students were also asked to fill out a questionnaire, obstensibly from the administration, asking them to rate the favorability of the first five periods of the day on a scale of 1-100. Two weeks later 94 of the above students, serving as controls, were asked to fill out the identical questionnaire again. They were told that the previous ones had been lost. The 98 remaining students, serving as experimental subjects, received additional information. E said that he had heard …

The Effects Of Contingency Management On Reading Achievement Of Institutionalized Offenders, Forest J. C. Hertlein

All Master's Theses

The hypotheses to be tested in this study are concerned with the use of contingency management. In general, the theory states that behavior normally occurring at a low rate may increase when it is followed by activities which are highly desirable to the student (Premack, 1965). Also suggested in the theory is that a response does not have a zero operant level (Bijou and Baer, 1961). It was assumed, then, that institutionalized offenders enrolled in remedial reading classes have an operant level of some degree for a specific response that could be strengthened by positively reinforcing that response. Because the …

Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler

All Master's Theses

Forty-eight rats were divided into 8 groups; four were maintained under normal conditions and the other four under sensory deprivation and tested at o, 3, 6, and 9 days after condition institution. The response was placing the head through a hole in the operant chamber and the stimulus (0, 1.2, 4, or 12 Vac) was contingent upon the response. Analysis ot variance disclosed significant differences (p<.01) between the deprived and the non-deprived groups at days 6 and 9; and a significant interaction between deprivation condition and time of test. No differences were shown between the stimulus intensities indicating that the stimulus did not have a reinforcing effect.

The Use Of Selected Films And Film Discussions In Modifying Social Distance In Elementary School Children, Stanton C. Baker

All Master's Theses

When conflicts involving interpersonal relationships arise within the school setting, it would appear appropriate to attempt to cope with these conflicts within the framework of the school; particularly the classroom. Many methods of modifying behavior through group procedures have been attempted with varying degrees of success. It was the purpose of this study to investigate the effectiveness of one such method; a fiIm-discussion technique. This program was developed to modify behaviors, attitudes and/or perceptions which interfere with the development of constructive interpersonal relationships within an elementary classroom.

Modification Of Deviant Behavior By Parents, Jeanne M. Gabourie

All Master's Theses

It is the purpose of this study (1) to determine if a child's deviant social behaviors can be effectively modified by his own parents; and (2) to determine if parents can be trained to use behavior modification techniques in the home.

The Meaning Of Two Categories Of Verbal Reinforcement To Middle And Lower Class Children, Steven John Talmadge

All Master's Theses

Many variables contribute to the effectiveness of social reinforcement in eliciting changes in children's behavior. To date, little work has been done on subject variables such as cognizance of reinforcement contingencies and preference for one type of reinforcement as opposed to another. In previous research the effectiveness of verbal, social reinforcers have been evaluated on task performance criteria (e.g., marble in the hole game) with Subjects in direct contact with the reinforcing agent. The present study investigated these variables by having children rate two categories of verbal, social reinforcers. One category was composed of student-centered statements and the other consisted …

Clarification Of The Role Of The Teacher Of The Elementary Educable Mentally Retarded Child In Tacoma, Washington, Stephen Melseth

All Master's Theses

The basic problem is what role expectations does the teacher of elementary EMR children think she has compared to what her principal thinks her role should be? Role expectation statements from four areas were considered: (1) Curriculum and Instruction; (2) School and Community Relations; (3) Administration and Organization; (4-) Guidance and Evaluation.

Three specific questions are cited:

(1) Is there consensus for selected role norm items, among teachers of the elementary EMR child?

(2) Is there consensus for selected role norm items among the building principals?

(3) Is there consensus for selected role norm items between the focal and counter …

Relationship Of Weather Phenomena And Disruptive Behavior In Special Education Classrooms, Carol Bartlett Ryno

All Master's Theses

If a clear-cut relationship between weather phenomena and human behavior could be established, the case for controlled atmosphere in industry, commerce, and education would be strengthened. In the area of education, classroom procedures and learning tasks could be varied in accordance with the weather. This dimension could provide for insights into misbehavior and might enable school personnel to deal with such misbehavior more effectively.

The purpose of the present investigation was to gather information pertaining to the relationship of various weather phenomena and disruptive behavior in the classroom. It was intended that the present study differ from that reported by …
