Specificity Of The Cardiac Response To Conspecific Vocalizations In Chimpanzees, Gary G. Berntson, Sarah T. Boysen

Sentience Collection

Heart rate measures were used to examine the functional response of young chimpanzees and orangutans to acoustic stimuli, including white noise and chimpanzee vocalizations (threat, stress, and alarm). The initial response of the animals to all stimuli was characterized by a prominent cardiac deceleration and an increase in heart period variability. The deceleratory responses persisted with repeated presentations of the noise, stress, and alarm stimuli. In contrast, the response of chimpanzees to the conspecific threat stimulus reverted over trials to a notable cardiac acceleration. This acceleratory response was not attributable to potential patterns of evoked somatic responses. The features of …

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

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

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

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 …

G89-928 Parent Checklist For Choosing Day Care, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

Choosing appropriate child care can be confusing. Here are some things to consider in selecting the best care for your child.

What Is Good Day Care?

Good day care requires three important things: a caregiver who provides your child with care and guidance and who works with you and your family to made sure your child grows and learns in the best way possible; a setting that keeps your child safe and healthy; activities suited to your child's stage of growth that help the child develop mentally, physically, socially and emotionally.

A Comparison Of Three Populations Of The Plains Pocket Gophers, Geomys Bursarius Illinoensis, In Illinois, Frank P. Wray

Masters Theses

Morphometric and karyotypic analyses were performed on three Illinois populations of the Plains Pocket Gopher, Geomys bursarius illinoensis, to determine if any differences were present among the populations. Gophers were collected in three localities: 1) Iroquois and Kankakee Counties (IKC); McLean County (MC); and St. Clair and Madison counties (SMC). All three populations had the same kind and number of chromosomes (2n=72, FN=70). External measurements did not differ significantly among the three populations. Multivariate analysis of variance of the cranial characters showed that a significant (P<.05) difference existed in both males, F(78,1825)=1.65, and females, F(78,1961)=1.63, between the three regions. Duncan's multiple range tests of some cranial measurements showed a clinal increase going from east to west.

Lasting Responsiveness Of A Kea (Nestor Notabilis) Toward Its Mirror Image, Judy Diamond, Alan B. Bond

Papers in Behavior in Biological Sciences

At the San Diego Zoo we had the opportunity of observing the behaviour of a Kea Nestor notabilis toward its mirror image under conditions of constant exposure over a period of 12 months. ... The introduction of the mirrors appears to have had a striking impact on the bird's listless state. Reports from keepers indicated that the Kea's appetite was restored after the introduction of the mirrors, and the animal was generally more active. Incidents of feather pulling were generally reduced in frequency.

Studies Of Learning And Memory In Natural Contexts : Integrating Functional And Mechanistic Approaches To Behavior, Alan Kamil

Papers in Behavior in Biological Sciences

My purpose in this paper is to describe two research projects that combine experimental psychology and behavioral ecology . The first employs the operant conditioning technology developed by psychologists to test hypotheses arising from ecological studies of foraging animals. The second uses concepts from natural history and ecology to explore the nature and evolution of spatial memory. These two projects demonstrate both the advantages and the challenges of interdisciplinary work.

There are many advantages to combining psychological and biological perspectives on the behavior of animals. But truly interdisciplinary work is rare, mostly because it is so difficult to achieve meaningful …

Toward A Resolution Of The Paradox Of Aggressive Displays: Ii. Behavioral Efference And The Communication Of Intentions, Alan B. Bond

Papers in Behavior in Biological Sciences

An inference from game-theory models of animal conflict is that adversaries should not inform one another about their level of aggressive motivation. This poses a paradox for the traditional ethological account of graded aggressive displays because it is usually assumed that the adaptive significance of these behavior patterns lies in their making such information available. To resolve the paradox, I propose that communication is only an incidental effect of displays, and that their primary adaptive function is regulation of the intensity of aggressive encounters through positive feedback on aggressive motivation, a process termed "behavioral efference." Evidence in support of this …

Characterization Of Steroid-17,20-Desmolase And 20Α-Hydroxysteroid Dehydrogenase From Clostridium Scindens, Amy Elizabeth Krafft

Theses and Dissertations

Clostridium scindens is an obligate anaerobe isolated from the normal intestinal flora of man. It is the only bacterium known at present to synthesize both steroid-17,20-desmolase and 20α-hydroxysteroid dehydrogenase (ZOα-HSDH). This study was undertaken to characterize these neutral steroid transforming reactions in extracts of C. scindens; to purify and characterize the enzymes responsible for side-chain cleavage and 20α- hydroxysteroid oxidoreduction and to clone the genes encoding these enzymes with a view towards studying the mechanism of induction by steroids in a prokaryotic system. Both enzymes were found to be co-inducible in cells cultured in the presence of 17α-hydroxysteroids. In cell …

Perceptions Of The Texas State And Federal Closures Among Inshore Shrimpers In Galveston Bay, Texas And Calcasieu Lake, Louisiana, Nina H. Garfield

Marine Affairs Theses and Major Papers

The inshore shrimp fisheries along the coast of the Gulf of Mexico represent a significant portion of the total shrimp harvest in the Gulf. The shrimp harvest is allocated to the offshore and inshore fisheries through the use of season closures. In 1981, the Gulf of Mexico Regional Fisheries Management Council began implementing a policy known as the Texas Closure; a seasonal closure of the waters of the Federal Conservation Zone concurrent with the traditional season closure of the state waters of Texas. One impact of the Texas Closure on the offshore fishery has been fleet displacement from Texas to …

Isolated Cataplexy: A Familial Study, Kristyna M. Hartse, Frank J. Zorick, Jeanne M. Sicklesteel, Thomas Roth

Henry Ford Hospital Medical Journal

Four members of a family, a mother, her two sons, and the mother's second cousin, presented with a history of isolated cataplexy without excessive daytime sleepiness or other symptoms typical of narcolepsy. They were polygraphically monitored during one night followed by a day of multiple nap tests. No subject manifested objective daytime sleepiness as measured by short latencies to sleep onset during daytime naps, and no subject exhibited periods of sleep onset rapid eye movement sleep in either the night or nap recordings. The incidence of isolated cataplexy in this family was traced by history through six generations. We conclude …

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 …
