Description¶
An experimental apparatus and procedure for studying latent inhibition in adult humans. Subjects attended to one ear of a dichotic tape recording, counting repetitions of paired nonsense syllables, while a white-noise CS was superimposed on one track. In the testing phase, subjects watched a scoreboard and pressed a button whenever they expected a point to be raised, aiming to bring their score down to zero. The criterion for learning was the number of CSs to termination of the experiment, and eye movements were monitored via a mirror to verify which ear was attended.
Design Implications¶
Context¶
Requirements¶
- Subjects must attend to the designated ear during preexposure, verified by monitoring eye movements
Constraints¶
- The experiment terminated either after five consecutive correct presses to the CS or after 31 presentations of the CS
Target Learners¶
- undergraduate psychology students
Learning Goals¶
- learning the rule connecting a white-noise CS to scoreboard point changes
Claims¶
- Latent Inhibition Adult Humans Instrumental Conditioning [+M]
- Latent inhibition in adults occurs even when the CS is preexposed under severe conditions of inattention [+W]
- The inattention manipulation was behaviorally verified: only one of 10 nonmonitored-ear subjects reported hearing the CS during preexposure versus eight of 10 monitored-ear subjects [+W]
- Latent inhibition occurs irrespective of whether preexposure was to the monitored or the nonmonitored ear [+W]
