Intermodal blocking in honeybees.
Previous findings of intramodal but not of intermodal blocking in foraging honeybees prompted a new series of experiments with colours, odours, a proximal visual landmark, and a localized geomagnetic anomaly as stimuli. In Experiments 1-2, the landmark was blocked by both colour and odour. In Experiments 3-6, the anomaly was blocked by both colour and odour, but the anomaly failed to block eith...
متن کاملBackward blocking in honeybees.
Three experiments with foraging honeybees were designed to study the effect of experience with A on responding to B after AB+ training. In the first experiment, responding to B was the same whether the AB+ training was preceded or followed by A+ training. In the second experiment, responding to B after AB+ training was less in animals that also had A+ training than in control animals that were ...
متن کاملBlocking in landmark-based search in honeybees
Blocking is by now a classic phenomenon in classical conditioning (Kamin, 1969). In blocking, what would have been learned about one conditioned stimulus (CS) is not learned or not expressed because of experience with another CS. In the first phase of training, a CS alone, CSA, is paired with the unconditioned stimulus (UCS). In the second phase of training, two CSs, CSA and CSB, are together p...
متن کاملBlocking and pseudoblocking: new control experiments with honeybees.
Prompted by doubts about the adequacy of the various control procedures long used in research on blocking, we repeated some earlier experiments with honeybees that had given the appearance of forward, concurrent, and backward blocking. The new experiments differed from the earlier experiments only in that the target stimulus was omitted during the training and was encountered for the first time...
متن کاملIntramodal Palmprint Authentication
Palmprint technology is one of the biometric techniques used to identify an individual. Recognition of palmprints is based on the features like palm lines, texture, ridges etc. Several line and texture extraction techniques have already been proposed. In this paper we propose a novel technique, filiformity to extract the line like features from the palm. We also extracted texture features using...
