Effect of unconditioned stimulus linked subconvulsive current in chicks

Unblocking with Qualitative Change of Unconditioned Stimulus

Conditioned barpress suppression was used to examine the effects of qualitative changes in the unconditioned stimulus (US) between Phases 1 and 2 of a blocking paradigm. In Phase 1, rats received pairings of a conditioned stimulus (CS) with footshock. In Phase 2, experimental subjects received a single trial of the same CS or a different CS compounded with a second stimulus and followed either ...

On the respective contributions of awareness of unconditioned stimulus valence and unconditioned stimulus identity in attitude formation through evaluative conditioning.

Evaluative conditioning (EC) is a central mechanism for both classic and current theories of attitude formation. In contrast to Pavlovian conditioning, it is often conceptualized as a form of evaluative learning that occurs without awareness of the conditioned stimulus-unconditioned stimulus (CS-US) contingencies. In the present research, the authors directly address this point by assessing the...

Retrograde amnesia gradients by subconvulsive and high convulsive transcranial currents in chicks.

Either a subconvulsive or a high convulsive current was delivered transcranially at various intervals after a learning trial to independent groups of newly hatched chicks. The one-trial learning involves suppression of the chicks' predilection to peck at a small shiny bead. The effect of current on retention was measured one day later. Results indicate a current-sensitive memory consolidation p...
