Blocking and backward blocking involve learned inattention.
Four experiments examine blocking of associative learning by human participants in a disease diagnosis procedure. The results indicate that after a cue is blocked, subsequent learning about the cue is attenuated. This attenuated learning after blocking is obtained for both standard blocking and for backward blocking. Attenuated learning after blocking cannot be accounted for by theories such as...
متن کاملDifferential Cue Salience, Blocking and Learned Inattention
A classic blocking design is modified by varying the relative salience of the blocked and the blocking cue. It is found that, in accordance with the learned inattention theory of blocking, the amount of blocking is diminished when the blocked cue is more salient than the blocking cue. In addition, when studying the patterns of answers about the control cues, it is found that low salience cues w...
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 rabbit eyeblink conditioning is not due to learned inattention: indirect support for an error correction mechanism of blocking.
Blocking is a classical conditioning task in which prior training to one cue such as a tone reduces learning about a second cue such as a light, when subsequently trained as a tone-light compound. Blocking has been theorized to come about through a US-modulated error correction mechanism by Rescorla & Wagner (1972) as well as through a mechanism of learned inattention as theorized by Mackintosh...
متن کاملBackward Blocking 1 Running Head: BACKWARD BLOCKING AND INTERFERENCE BETWEEN CUES Backward Blocking and Interference between Cues are empirically equivalent in non-causally framed learning tasks
Backward blocking (BB) and interference between cues (IbC) are cue competition effects produced by very similar manipulations. In a standard BB design both effects might occur simultaneously, which implies a potential problem to study BB. In the present study with humans, the magnitude of both effects was compared using a non causal scenario and a within subjects design. Previous studies have m...
