The phenomenon of blocking provides an interesting and much-studied instance of failure to learn, in spite of contiguous presentations of CS and US. In a blocking experiment, animals receive training with what is termed a compound CS (Phase 2) – in this example represented by the simultaneous presentation of a noise and a light followed by a shock reinforcer. However, the experimental group has first received a phase of training in which the noise alone is conditioned (Phase 1).
The performance of the control group of participants shows that training (Phase 2) with a compound CS is normally sufficient to establish associations between individual CS elements (noise, light) and the US (shock). So in this control group the light, when subsequently presented on its own, will evoke a CR. But the experimental group shows no (or very little) evidence of learning about the light in Phase 2. Although they have received light–US pairings, just as the control participants have, in Phase 2, the formation of the light–US association appears to have been blocked by initial training with the noise in Phase 1.

Blocking in Conditioning:
Blocking is a phenomenon in classical conditioning where an organism fails to learn a new association between a stimulus (CS) and an outcome (US) due to previous conditioning experiences. Here are the two true statements regarding blocking:
1. The phenomenon of blocking:
- The phenomenon of blocking provides an interesting and much-studied instance of failure to learn, despite contiguous presentations of the CS and the US. This means that even though the CS and the US are presented together, the organism does not form the expected association.
- This failure to learn is often seen as evidence that the organism's learning is influenced by prior learning experiences, specifically when the US has already been associated with another CS.
2. Blocking Experiment:
- In a blocking experiment, animals receive training with what is termed a compound CS in Phase 2. This compound CS consists of the original CS and a new CS presented together.
- The experimental group in the blocking experiment has first received a phase of training in which the US alone is conditioned (Phase 1). This initial conditioning phase with the US alone can lead to blocking in the subsequent phase.
Therefore, the correct statements are 1 and 2, as they accurately describe the phenomenon of blocking in classical conditioning experiments.
