Answer:
d. the echo faded before being stored in short-term memory.
Explanation:
The MOST plausible explanation for this phenomenon is that, in the latter case, <em>the echo faded before being stored in short-term memory</em>. Memory is the function that allows human beings to store experiences and to recall them when they are needed. Memory has three stages: sensory memory, short-term memory, and long-term memory. Sensory memory stores memories less than a second after the stimulus has stopped. In this experiment as the instructions came more than three seconds after the stimulus had stopped the students could not store it in short-term memory.
