Key Pecking

Conditions necessary for the development of social interaction were examined with 7 Observer pigeons, each working beside a Model pigeon. Observer was conditioned to pay attention to the Model's behavior. Model's key pecking rate on a multiple fixed-ratio, extinction schedule was controlled by stimuli projected on his key (not visible to Observer), but Observer, whose key always remained the same color, had no discriminative stimuli except those provided by Model's behavior. More precise control of Observer's behavior occurred when Model could be both seen and heard than when Model could be heard only.

Inspection Task

The problem of sustained efficiency in monotonous perceptual tasks is particularly pertinent to industrial inspection. The present research has extended Holland's techniques of behavioral analysis to an industrial framework by analyzing the assembly-line inspection of products. By utilizing four basic schedules of defective product (fixed ratio, variable ratio, fixed interval, and variable interval), it was demonstrated that the detection of defectives can serve as reinforcements for observing behavior. In addition, the vigilance decrement associated with the inspection task was shown to be a function of the differential reinforcement of observing responses. The fact that a rather precise control can be exerted by the environment over the operator's observing behavior has important implications for industry. Some of these implications are discussed.

Novel Behaviour

Social learning is said to occur when social interaction facilitates the acquisition of a novel pattern of behaviour. It usually takes the form of an experienced animal (the demonstrator) performing a behaviour such that a naive animal (the observer) subsequently expresses the same novel behaviour, earlier or more completely than it would have done using individual learning. Social learning is involved in the transmission of a great variety of behaviours, e.g. tool-use, food preferences, and has also been implicated in maladaptive behaviours such as stereotypies in voles. In studies of social learning, the observers usually see the demonstrators receive a reward for performing the required behaviour. But, the role of the reward has rarely been investigated and results have been equivocal. Understanding the role of demonstrator reward on social learning is necessary to assess the cognitive abilities of individuals of different species, and aids understanding of the transmission of maladaptive behaviours.

Ad Libitum Feeding

Four groups of 6 pigeons, maintained at 100, 90, 80, and 70% of their ad libitum feeding weight, showed directly proportional weight-dependent depressant effects on fixed ratio key pecking following d-amphetamine treatment.
