“…In the present studies, daily intake was constant across a wide range of both unit and meal-initiation prices; intake was reduced only at the highest prices. Previous work has shown that for a number of species in the free-feeding paradigm, daily intake declines to some extent as within-meal prices increase, but is unaffected by meal-initiation prices (with rats: Jensen, Collier, & Medvin, 1983;Kanarek, 1976;Kanarek & Collier, 1979;Kaufman & Collier, 1983;with cats: Collier, Kaufman, Kanarek, & Fagan, 1978;Kanarek, 1975;Kaufman, Collier, Hill, & Collins, 1980;with guinea pigs: Hirsch & Collier, 1974;with chickens: Kaufman & Collier, 1983). These results suggest that the changes in intake seen in the classic refinement paradigm as a function of schedule and magnitude of reinforcement may be comparable to that seen here as high feeding costs became limiting.…”

A corollary of the law of effect predicts that the larger the reinforcement, the greater the rate of responding. However, an animal must eat more small portions than large portions to obtain the same daily intake, and one would predict, therefore, that when eating smaller portions an efficient animal would eat less (conserving time and energy) and/or respond faster (conserving time). The latter of these predictions was supported by the present experiments with free-feeding rats for which portion size (pellet size or duration of feeder presentation) and portion price within meals were varied. Response rate was a function of the unit price (responses/g) of food: Rats responded faster when portions were smaller or when prices were higher. Meal size and frequency were relatively unaffected by unit price, but were influenced by the price of meal initiation. The results are discussed in relation to the economic differences between traditional operant and free-feeding paradigms and to both traditional and more recent formulations of the law of effect.

“…Maintaining dietary diversity appears to be an adaptive means of addressing specific nutritional demands. Many owners feed their cats once or twice a day, sometimes giving more than their cats can eat in a single meal (Kaufman et al 1980). When owned cats have ad libitum access to food, they eat 7-20 small meals daily (Mugford 1977), more closely resembling wild-type feeding patterns, hence feeding other than ad libitum might prompt more frequent hunting.…”

Drivers and facilitators of hunting behaviour in domestic cats and options for management

1. Domestic cats Felis catus are distinct from other domesticated animals because their phenotype and genotype are relatively unchanged. While they live with people as pets or pest controllers, they retain capacity for survival independent of human support and readily persist as feral animals. Most cats retain some propensity to express hunting behaviours, even if hunting is not required for nutrition. In some settings, depredation by cats is a threat to biodiversity conservation, leading to attempts to mitigate their impacts. 2. We characterise drivers and facilitators of the hunting behaviour of domestic cats: evolutionary origins, diet, life history, personality and environment.Hunting is driven particularly by evolutionary constraints and associated physiological and nutritional requirements. Proximate causes of variation in hunting behaviours relate to prey availability, husbandry and degree of domestication, while early life history and personality play further roles. 3. We review cat management approaches in terms of effectiveness, feasibility and welfare. Amongst lethal, large-scale methods of population control, poisoning is most frequently used in cat eradications from islands. Because poisoning is challenged on welfare grounds, euthanasia is used at smaller scales and in inhabited, mainland settings. Non-lethal approaches, primarily surgical sterilisation, are favoured by cat advocates but entail challenging logistics and scale. In attempts to inhibit predation of wild species by pet cats, owners restrict outdoor access and use collar-mounted devices, including bells, sonic devices, collar covers and bibs. Other individual-level interventions, such as dietary and behavioural enrichment, some of which may improve cat welfare, have potential, but effects on hunting remain untested. 4. Understanding and managing the hunting behaviour of cats are complex challenges. We highlight drivers and facilitators of this behaviour, representing starting points for formulating solutions that might be acceptable to cat owners and wider groups of people who value cat welfare, while also being effective for wildlife conservation.

“…Several behavioral investigators have emphasized how response costs or constraints affect operant response output (Staddon, 1979; Kaufman, 1980; Kaufman et al, 1980; Foltin, 1991). Collier and colleagues studied how work requirements, such as the number of lever presses necessary for obtaining food, could serve as determinants of response output and affect consumption parameters (Collier and Jennings, 1969; Johnson and Collier, 1987).…”

There are numerous problems with the hypothesis that brain dopamine (DA) systems, particularly in the nucleus accumbens, directly mediate the rewarding or primary motivational characteristics of natural stimuli such as food. Research and theory related to the functions of mesolimbic DA are undergoing a substantial conceptual restructuring, with the traditional emphasis on hedonia and primary reward yielding to other concepts and lines of inquiry. The present review is focused upon the involvement of nucleus accumbens DA in behavioral activation and effort-related processes. Viewed from the framework of behavioral economics, the effects of accumbens DA depletions and antagonism on food-reinforced behavior are highly dependent upon the work requirements of the instrumental task, and DA depleted rats are more sensitive to increases in response costs (i.e., ratio requirements). Moreover, interference with accumbens DA transmission exerts a powerful influence over effort-related choice behavior. Rats with accumbens DA depletions or antagonism reallocate their instrumental behavior away from food-reinforced tasks that have high response requirements, and instead these rats select a less-effortful type of food-seeking behavior. Nucleus accumbens DA and adenosine interact in the regulation of effort-related functions, and other brain structures (anterior cingulate cortex, amygdala, ventral pallidum) also are involved. Studies of the brain systems regulating effort-based processes may have implications for understanding drug abuse, as well as energy-related disorders such as psychomotor slowing, fatigue or anergia in depression and other neurological disorders.
