Question 1

Which of the following best describes the function of the short-term sensory store (STSS) in the information processing model?

Accepted Answer

It stores vast amounts of sensory information (auditory, visual, kinesthetic) for a very brief period, allowing some of it to be abstracted and further processed.

Question 2

According to the information processing model, which factor would most likely increase the speed of response selection?

Accepted Answer

Increasing the amount of practice under consistent conditions.

Question 3

A student is able to recall a phone number for a short time after hearing it but forgets it soon after. Which memory system is primarily involved in this scenario?

Accepted Answer

Short-term memory (STM)

Question 4

In the Sperling experiment (1960), what did the results demonstrate about sensory memory?

Accepted Answer

Sensory memory can hold a large amount of information for a very brief period, but most is lost unless attended to.

Question 5

Which of the following best illustrates the concept of 'controlled processing' in response selection?

Accepted Answer

Counting the number of occurrences of the letter 'a' on a slide.

Question 6

A basketball player misses a crucial free throw during a high-pressure game, despite normally performing well. Which psychological concept best explains this phenomenon?

Accepted Answer

Choking under pressure

Question 7

Which equation correctly represents the reaction time (RT) for the second stimulus ($$S_2) in $$the Psychological Refractory Period (PRP) when the stimulus onset asynchrony (SOA) is between 50 ms and 200 ms?

Accepted Answer

$$RT_{S_2$} = RT_{S_1$} + 100$$

Question 8

Which of the following is a real-world example of the information processing bottleneck?

Accepted Answer

A driver hesitating to brake when two hazards appear almost simultaneously on the road.

Question 9

Which statement about automaticity is most accurate?

Accepted Answer

Automaticity is developed through a large amount of practice, especially under consistent conditions, but can lead to errors if the environment changes suddenly.

Question 10

Which of the following factors is NOT known to affect sustained attention?

Accepted Answer

Short-term memory capacity

Question 11

According to the Inverted-U Principle, what happens to performance as arousal increases beyond the optimal level?

Accepted Answer

Performance decreases due to perceptual narrowing and slower reaction times.

Question 12

Which of the following best describes perceptual narrowing?

Accepted Answer

The tendency for the perceptual field to shrink under stress with high arousal, focusing attention on the most relevant stimuli.

Question 13

Which scenario best illustrates the double stimulation paradigm?

Accepted Answer

A subject must respond with separate actions to two stimuli presented very closely together in time, leading to delays due to interference in movement programming.

Question 14

Which of the following is true about the transition of information from short-term memory (STM) to long-term memory (LTM)?

Accepted Answer

It requires attention and effortful processing, such as rehearsal and encoding.

Question 15

A person is texting while walking and fails to look both ways before crossing the street. Which stage of the information processing model is most affected?

Accepted Answer

Response selection

Question 16

Which of the following equations best represents the relationship between arousal and performance according to the Inverted-U Principle?

Accepted Answer

$$Performance = -a(Arousal - b)^2$ + c$$

Question 17

Which of the following is a limitation in stimulus identification?

Accepted Answer

Parallel processing

Question 18

Which of the following statements about memory systems is correct?

Accepted Answer

Long-term memory (LTM) has unlimited duration and capacity.

Question 19

Which of the following best explains why performance may decrease under high stress according to the Attentional Control Theory of Anxiety?

Accepted Answer

Attention to the current goal is reduced in the presence of threatening internal or external stimuli.

Question 20

A driver is distracted by a phone conversation while operating a vehicle. According to research, which stage of the information processing model is most impacted?

Accepted Answer

Response selection
