	Title	Acquisition, extinction, and reacquisition of responding with delayed and immediate reinforcement			Type	Journal Article
	Year	1998	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	43	Issue	1	Pages	97-101
	Keywords	Acquisition; Delayed reinforcement; Extinction; Rats
	Abstract	The present study investigated acquisition, extinction, and reacquisition of free-operant responding when rats' lever presses produced water after a resetting delay of 0, 10, 20, or 30 s. Results indicated that: (1) responding was acquired rapidly at all delays without shaping or autoshaping; (2) resistance to extinction was directly related to delay length and inversely related to intermittency of reinforcement; (3) responding acquired with delayed reinforcement recovered less rapidly from extinction, and was less efficient, than responding acquired with immediate reinforcement. Comparing these results with those of studies using discrete-trials and free-operant procedures with no reinforcement delay suggest that the specific conditions under which behavior is maintained determines, in part, the behavioral effects of delay and intermittency of reinforcement.

	Title	Altering “motivational” variables alters induction produced by upcoming food-pellet reinforcement			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	1	Pages	17-26
	Keywords	Animals; Conditioning, Operant; Food Deprivation; Male; Motivation; Rats; Rats, Sprague-Dawley
	Abstract	Previous research has demonstrated that rats will increase their rates of lever pressing for sucrose rewards in the first half of an experimental session when food pellets, rather than the same sucrose, continually serve as the reward in the second half of the session. This effect has been coined induction, and the present study investigated whether it could be altered by altering “motivational” variables. Experiment 1 manipulated subjects' motivation by altering, across conditions, their level of food deprivation. Predictably, the size of induction varied directly with level of deprivation. Experiments 2 and 3 manipulated subjects' motivation by feeding them food pellets and sucrose, respectively, prior to their responding in the experimental session. These pre-session feedings decreased the size of the observed induction in both experiments. The results from the present study indicate that the size of induction is correlated with subjects' motivation to respond for the available reinforcers. They are also consistent with the idea that operant processes underlie the effect. The notion that induction might encompass the concept of “anticipation” is also discussed.

	Title	Appetitive latent inhibition in rats: preexposure performance does not predict conditioned performance			Type	Journal Article
	Year	2006	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	72	Issue	1	Pages	42-51
	Keywords	Animals; Appetitive Behavior; Association Learning; Conditioning, Classical; Habituation, Psychophysiologic; Individuality; Inhibition (Psychology); Male; Motivation; Rats; Rats, Wistar; *Reaction Time
	Abstract	Nonreinforced preexposure to a conditioned stimulus impairs subsequent conditioning with that stimulus. The goal of these studies was to assess the extent to which acquisition performance could be predicted from preexposure performance using a correlational approach. For both preexposure and autoshaping, four measures of performance were computed, including overall average lever pressing, lever pressing in the initial session, percentage change in lever pressing, and slopes. These measures were correlated in a large sample of rats trained in an autoshaping situation. None of the three measures of autoshaping performance was consistently predicted by any of the three measures of preexposure performance. These results are consistent with the view that latent inhibition is not reducible to long-term habituation.

	Title	Behavioral comparability of wild and domesticated rats			Type	Journal Article
	Year	1981	Publication	Behavior Genetics	Abbreviated Journal	Behav Genet
	Volume	11	Issue	5	Pages	545-553
	Keywords	Animals; Behavior, Animal; Female; Genetics, Behavioral; Intelligence; Learning; Male; Rats/genetics
	Abstract	The oft-repeated concern for the lack of behavioral comparability of domestic rats with wild forms of Rattus norvegicus is unfounded. Laboratory rats appear to show the potential for all wild-type behaviors, including the most dramatic social postures. Moreover, domestics are capable of assuming a feral existence without difficulty, one where they readily behave in a fashion indistinguishable from wild rats. The one behavioral difference that is clearly established concerns performance in laboratory learning paradigms. The superiority of domestics in these laboratory tasks speaks more to quieting the concerns of degeneracy theorists than to problems of using domestic Norway rats as subjects representative of their species.

	Title	Biomechanics of tendon healing			Type	Journal Article
	Year	1982	Publication	Journal of Biomechanics	Abbreviated Journal	J Biomech
	Volume	15	Issue	12	Pages	951-958
	Keywords	Achilles Tendon/injuries; Animals; Biomechanics; Rats; Tendon Injuries/pathology/physiopathology; Tensile Strength; Time Factors; Wound Healing
	Abstract	The biomechanics of tendon healing was investigated with unsutured rat achilles tendons. After two, three, and four weeks of healing tensile parameters were assayed with a bone-muscle-tendon-bone preparation elongated to failure at a controlled physiological strain rate. In the third week of healing, stiffness, strength, and energy absorbing capacity all increased approximately 50%. These changes correlated with early fibroplasia. In the fourth week of healing, strength, energy absorbing capacity and elongation to failure all increased relatively more than stiffness. Histologically, larger fibers with better longitudinal alignment developed during this period. At the end of four weeks the tendon's strength was approximately 25% of normal. To summarize, the return of stiffness in a healing tendon preparation correlated with the presence of fibroplasia and the return of other tensile parameters was a function of the amount and organization of the fibroplasia.

	Title	Causal reasoning in rats			Type	Journal Article
	Year	2006	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	311	Issue	5763	Pages	1020-1022
	Keywords	Animals; Association Learning; Bayes Theorem; Cognition; Comprehension; Forecasting; Male; Rats; Rats, Long-Evans
	Abstract	Empirical research with nonhuman primates appears to support the view that causal reasoning is a key cognitive faculty that divides humans from animals. The claim is that animals approximate causal learning using associative processes. The present results cast doubt on that conclusion. Rats made causal inferences in a basic task that taps into core features of causal reasoning without requiring complex physical knowledge. They derived predictions of the outcomes of interventions after passive observational learning of different kinds of causal models. These competencies cannot be explained by current associative theories but are consistent with causal Bayes net theories.

	Title	Chunking versus foraging search patterns by rats in the hierarchically baited radial maze			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	2	Pages	93-104
	Keywords	Animals; Exploratory Behavior; Feeding Behavior; Male; Maze Learning; Rats; Rats, Long-Evans
	Abstract	Rats were exposed to a radial maze containing six black smooth arms and six wire-grid-covered arms and a striped 'exit arm' in experiment 1. The probability of a black or grid arm being baited (5/6 vs 1/6) with sunflower seeds was associated with its proximal cue for some rats (the Relevant Arm Cue group) but not for others (the Irrelevant Arm Cue group). All rats could terminate a trial and receive a highly preferred morsel of apple by entering the exit arm only after having sampled all six seed-baited arms. Relevant Arm Cue rats usually chose some arms from the more densely baited set before choosing an arm from the less densely baited set and made fewer reentries than Irrelevant Arm Cue rats. Although such clustered, higher choice accuracy in the Relevant Arm Cue group corresponds to human clustered, better recall of verbal items from lists hierarchically organized by categories, these rats did not similarly exhaustively retrieve items (arm locations). That is, when required to terminate a trial by entering the 'exit' arm for an apple morsel after having sampled all seed-baited arms, both groups were equally unable to withhold making nonrewarded premature exits. This nonexhaustive foraging search pattern was maintained in the next two experiments in which the radial maze was reduced to three black and three grid arms along with the striped 'exit' arm and in which black and grid arm cues were paired with number of seeds (eight or one) in an arm for Relevant Arm Cue rats. Although Relevant Arm Cue rats displayed perfect clustering by entering all eight-seeded arms before a one-seeded arm, they made more premature exits and reentries into eight-seeded arms in experiment 2 or when forced to enter all eight-seeded arms in experiment 3 than did Irrelevant Arm Cue rats. These foraging tendencies prevent accurate estimations of the amount of information (i.e., arm locations) rats can 'chunk'.

	Title	Competition among spatial cues in a naturalistic food-carrying task			Type	Journal Article
	Year	2003	Publication	Learning & behavior : a Psychonomic Society publication	Abbreviated Journal	Learn Behav
	Volume	31	Issue	2	Pages	143-159
	Keywords	Adaptation, Psychological; Animals; Appetitive Behavior; Association Learning; Attention; Choice Behavior; Cues; Discrimination Learning; Male; Rats; Rats, Long-Evans; Space Perception; *Spatial Behavior
	Abstract	Rats collected nuts from a container in a large arena in four experiments testing how learning about a beacon or cue at a goal interacts with learning about other spatial cues (place learning). Place learning was quick, with little evidence of competition from the beacon (Experiments 1 and 2). Rats trained to approach a beacon regardless of its location were subsequently impaired when the well-learned beacon was removed and other spatial cues identified the location of the goal (Experiment 3). The competition between beacon and place cues reflected learned irrelevance for place cues (Experiment 4). The findings differ from those of some studies of associative interactions between cue and place learning in other paradigms.
