Law And Biology: Toward An Integrated Model Of Human Behavior, Owen D. Jones Jan 1997

Law And Biology: Toward An Integrated Model Of Human Behavior, Owen D. Jones

Vanderbilt Law School Faculty Publications

As first year law students unhappily discover, the meaning of "law" is frustratingly protean, shifting by usage and user. Depending on whom you ask, law is a system of rules, a body of precedents, a legislative enactment, a collection of norms, a process by which social goals are pursued, or some dynamic mixture of these. Law's principal purpose is to define and protect individual rights, to ensure public order, to resolve disputes, to redistribute wealth, to dispense justice, to prevent or compensate for injury, to optimize economic efficiency, or perhaps to do something else. And yet one thing is irreducibly …

The Energetic Costs Of Rough And Tumble Play In The Juvenile Rat, Stephen M. Siviy, Dale M. Atrens Mar 1992

The Energetic Costs Of Rough And Tumble Play In The Juvenile Rat, Stephen M. Siviy, Dale M. Atrens

Psychology Faculty Publications

The metabolic costs of rough-and-tumble play behavior were studied in juvenile rats. Using indirect calorimetry, it was determined that energy expenditure during play is increased by 66-104% over the resting metabolic rate, indicating that play accounts for between 2% and 3% of the total daily energy budget of the rat. In a subsequent experiment, food intake and body weight were monitored for three weeks in rats allowed to play for one hour per day and in rats not allowed to play. While the body weights of the two groups did not differ significantly from each other, those rats allowed to …


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 …


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 …


Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil Jan 1969

Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil

Papers in Behavior in Biological Sciences

The effects of CS1 duration, partial reinforcement, and trace conditioning on second-order conditioned suppression were investigated, employing 64 rats as Ss. In Experiment 1, the clearest second-order conditioning was obtained when CS1 duration was the same during both the first- and the second-order conditioning phases of the experiment. In Experiment 2, somewhat better second-order conditioning was obtained when first-order conditioning had been under conditions of partial reinforcement, delay CS-US pairing. In neither experiment were CS1 suppression and CS2 suppression during second-order testing well correlated. This aspect of the results raised the question of the influence of nonclassical conditioning factors on …


The Inadequacy Of Intracranial Stimulation To The Posterior Hypothalamus To Serve As A Reinforcer For Maze Learning In The Rat, John A. Bull Aug 1965

The Inadequacy Of Intracranial Stimulation To The Posterior Hypothalamus To Serve As A Reinforcer For Maze Learning In The Rat, John A. Bull

All Master's Theses

Eighteen, 23 hour food deprived, self-stimulating rats were divided into two groups. One group received 20 ICS pulses as a reward for a correct response in a T-maze while the second group received a food reward. The subjects learned for food over 5 days of 10 massed trials per day, but failed to show learning for ICS either within sessions or over days. There was no difference in learning between rats with high bar press rates and those with low rates in either group.
