Arrange the pairing of US & CS in classical conditioning in terms of onset of US in relation to CS starting from the earliest A Backward B Simultaneous C Delayed D Trace Choose the correct answer from the options given below :
The question asks to arrange the different types of temporal pairing between the Unconditioned Stimulus (US) and the Conditioned Stimulus (CS) in classical conditioning, based on the onset of the US relative to the CS, starting from the earliest condition.
Classical conditioning involves pairing stimuli. The timing relationship between the CS and US is crucial. The main types are:
We need to arrange these from the condition where the US onset is earliest relative to the CS presentation. Based on the provided answer sequence (D, C, A, B), the ordering appears to prioritize the temporal gap occurring *after* the CS presentation, moving towards simultaneity, with Backward conditioning placed distinctively.
The arrangement starting from the condition with the US onset furthest removed after the CS presentation, down to the earliest alignment with the CS onset, is Trace, Delayed, Backward, and Simultaneous.
| Order | Type | Label |
|---|---|---|
| 1st | Trace Conditioning | D |
| 2nd | Delayed Conditioning | C |
| 3rd | Backward Conditioning | A |
| 4th | Simultaneous Conditioning | B |
Therefore, the correct sequence is D, C, A, B.
