  2. conditioned stimulus

  3. unconditioned response

  4. conditioned response

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

After repeated pairing of CS and US, the organism begins responding to the conditioned stimulus (CS) alone. This learned response to the CS is called the conditioned response (CR). The unconditioned stimulus (US) naturally triggers the unconditioned response (UR) without learning.

What function does control serve?

Directions: Read the following passage and answer the question.
In general, every stimulus directs activity. It does not simply excite it or stir it up, but directs it toward an object. Put the other way around, a response is not just a reaction, a protest, as it were, against being disturbed; it is, as the word indicates, an answer. It meets the stimulus, and corresponds with it. A light is the stimulus to the eye to see something, and the business of the eye is to see. If the eyes are open and there is light, seeing occurs; the stimulus is but a condition of the fulfillment of the proper function of the organ, not an outside interruption. To some extent, then, all direction or control is a guiding of activity to its own end; it is an assistance in doing fully what some organ is already tending to do.
This general statement needs, however, to be qualified in two respects. In the first place, except in the case of a small number of instincts, the stimuli to which an immature human being is subject are not sufficiently definite to call out, in the beginning, specific responses. Compare the behavior of a beginner in riding a bicycle with that of the expert. There is little axis of direction in the energies put forth; they are largely dispersive and centrifugal. Direction involves a focusing and fixating of action in order that it may be truly a response, and this requires an elimination of unnecessary and confusing movements. In the second place, although no activity can be produced in which the person does not cooperate to some extent, yet a response may be of a kind which does not fit into the sequence and continuity of action. A person boxing may dodge a particular blow successfully, but in such a way as to expose himself the next instant to a still harder blow. Adequate control means that the successive acts are brought into a continuous order; each act not only meets its immediate stimulus but helps the acts which follow.
In short, direction is both simultaneous and successive. At a given time, it requires that, from all the tendencies that are partially called out, those be selected which center energy upon the point of need.  Successively, it requires that each act be balanced with those which precede and come after, so that order of activity is achieved. Focusing and ordering are thus the two aspects of direction, one spatial, the other temporal. The first insures hitting the mark; the second keeps the balance required for further action.  Obviously, it is not possible to separate them in practice as we have distinguished them in idea. Activity must be centered at a given time in such a way as to prepare for what comes next. The problem of the immediate response is complicated by one's having to be on the lookout for future occurrences.

  1. It serves to determine action.

  2. It serves to determine the intensity of action.

  3. It predetermines action.

  4. It sets the stage for the initiation of action.

A Correct answer
Explanation

(1) “Adequate control means that the successive acts are brought into a continuous order; each act not only meets its immediate stimulus but helps the acts which follow.” In other words, control determines action.

(2) Intensity of action cannot be derived from the passage.
(3) Since “direction is both simultaneous and successive” it does not pre-determine, but determines.
(4) Setting the stage is akin to preparatory work, but control goes well beyond the preparatory. (5) Control goes well beyond the motivation.

Multiple choice
  1. Conjugate eye movements

  2. Vergence eye movements

  3. Saccadic eye movements

  4. Smooth pursuit movements

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Conjugate eye movements are those that preserve the angular relationship between the right and left eyes. For example, when you move both eyes left and then right, a conjugate movement is made. Up and down movements and combinations of vertical and lateral movements also fall into the conjugate category.
