Behavioral Psychology and Physiology Questions

Multiple choice
  1. occur when we can first detect some stimulus

  2. occur when we can detect the change in the intensity of a stimulus

  3. depend on the energy necessary to stimulate a sensory receptor

  4. are measured in Judgmental Normal Differences

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

Difference threshold refers to the minimum change in stimulus intensity that can be detected. This is also called Just Noticeable Difference (JND). Option A describes absolute threshold, C describes energy for receptors, and D is not a real measurement term. Difference thresholds are about detecting CHANGES, not initial detection.

Multiple choice
  1. The number of mistakes a person makes

  2. The amount of time a person needs to clap their hands when instructed

  3. The brain activity that follows exposure to a stimulus

  4. How quickly a person can blink their eyes after being told to do so

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

Speed of processing in cognitive psychology is measured by brain activity following stimulus exposure, typically using event-related potentials (ERPs) or reaction time tasks. The number of mistakes (A) measures accuracy not speed. Options B and D refer to specific motor tasks but not standardized processing speed measures. Brain activity measurement (C) is the most accurate general description of processing speed assessment techniques.

Multiple choice
  1. occur after the response

  2. occur before the response

  3. occur simultaneously with the response

  4. are unrelated to the response except during extinction

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

Thorndike's law of effect states that responses followed by satisfying consequences become more likely to occur again. The critical consequence must occur AFTER the response, not before or during it. This timing is essential for learning to take place.

Multiple choice
  1. unconditioned stimulus

  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

Prolonged eye contact between two individuals is weighted with great significance because

Directions: Read the passage and answer the given question.

One of the most potent elements in body language is eye behaviour. You shift your eyes, meet another person's gaze or fail to meet it - and produce an effect out of all proportion to the trifling muscular effort you have made. When two people look searchingly into each other's eyes, emotions are heightened and  the relationship tipped toward greater intimacy.

In normal conversation, each eye contact lasts only about a second before one or both individuals look away. Because the longer meeting of the eyes is rare, it is weighted with significance when it happens and can generate a special kind of human-to-human awareness. Most of the time, a lingering look is inter­preted as a sign of attraction and this should be scru­pulously avoided except in appropriate circumstances. A young woman once complained. ‘That man makes me so uncomfortable, half the time when I glance at him he's already looking at me - and he keeps right on looking.'

Proper street behaviour requires a balance of at­tention and intention. You are supposed to look at a passer-by just enough to show that you are aware of his presence. If you look too little, you appear haughty or furtive; too much and you are inquisitive. Usually what happens is that people eye each other until they are about eight feet apart, at which point both cast down their eyes.

Much of eye behaviour is so subtle that we react to it only on the intuitive level. This has been demon­strated in elaborate experiments. Subjects sit and talk in the psychologist's laboratory, irrespective of the fact that their eye behaviour is being observed from be­hind a one-way vision screen. In one fairly typical ex­periment, subjects were induced to cheat while per­forming a task, then were interviewed and observed. It was found that those who. had cheated met the interviewer's eyes less often than was normal, an in­dication that 'shifty eyes' can actually be a tip-off to an attempt to deceive.

However, none of the `facts' of eye behaviour are cut and dried, for there are variations between indi­viduals. People use their eyes differently and spend different amounts of time looking at others. Besides, no pattern of eye behaviour is precisely predictable in any normal conversation.

  1. it always generates a special awareness

  2. such contacts are extremely rare

  3. such contacts are often interpreted negatively

  4. such contacts create a great impression

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

The passage states: 'In normal conversation, each eye contact lasts only about a second. Because the longer meeting of the eyes is rare, it is weighted with significance when it happens.' Option B correctly identifies that prolonged contacts are rare.
