Correct answer: diffusion of responsibility. Explanation: Members of a group will often feel less inclined to do something about a situation; the larger the group, the less an individual will feel a sense of responsibility to take charge. This is called a "diffusion of responsibility" and is thought to be responsible for the "bystander effect ... theory that cones are activated by light waves associated with blue, red, and green and can then see all colors by mixing these three. opponent process theory contends that cells within the thalamus respond to opponent pairs of receptor sets (black/white, red/green, blue/yellow), and when one color is activated, the other is essentially turned offRatcliff, R.
