Accepted Answer

The claim relies heavily on anecdotal evidence and lacks openness to peer review.

Question 4

Which of the following best describes the difference between descriptive and inferential statistics?

Accepted Answer

Descriptive statistics summarize data, while inferential statistics allow us to draw conclusions about populations from samples.

Question 5

A psychologist is interested in the heritability of intelligence. Which research design would best help her estimate the genetic contribution to intelligence?

Accepted Answer

Twin studies comparing identical and fraternal twins raised together and apart.

Question 6

Which of the following equations correctly represents the calculation of the standard deviation $$s$$ for a sample of $$n$$ scores $$x_1$$, $$x_2$$, ..., x_n$$ with mean $$\bar{x}$$?

Accepted Answer

$$s = \sqrt{\frac{1}{n-1} \sum_{i=1}^{n} (x_i - \bar{x})^2$}$$

Question 7

Which of the following best describes the process of an action potential in a neuron?

Accepted Answer

A rapid electrical impulse that travels down the axon, caused by the movement of sodium and potassium ions across the membrane.

Question 8

Which of the following is an example of top-down processing in perception?

Accepted Answer

Interpreting a blurry image as a familiar face based on prior experience.

Question 9

A patient suffers damage to the hippocampus and is unable to form new explicit memories, but can still learn new motor skills. This pattern of memory loss is best described as:

Accepted Answer

Anterograde amnesia affecting explicit (declarative) memory but sparing implicit (procedural) memory.

Question 10

Which of the following best illustrates the reconstructive nature of memory?

Accepted Answer

A witness recalls details of a crime that were suggested by leading questions, not actually observed.

Question 11

Accepted Answer

Variable ratio schedule

Question 13

Which of the following is an example of observational learning?

Accepted Answer

A child learns to tie their shoes by watching their older sibling do it.

Question 14

Question 15

Which of the following is a common misconception about heritability?

Accepted Answer

Heritability applies to groups, not individuals, and does not indicate whether a trait can be changed.

Question 16

Which of the following best describes the function of the corpus callosum in the brain?

Accepted Answer

It connects the left and right hemispheres, allowing communication between them.

Question 17

A person is able to detect a candle flame 30 miles away on a clear night. This threshold is an example of:

Accepted Answer

An absolute threshold

Question 18

Which of the following best describes the process of long-term potentiation (LTP) in memory?

Accepted Answer

A long-lasting strengthening of synaptic connections between neurons, increasing the efficiency of neural transmission.

Question 19

Which of the following is a potential danger of pseudoscience in psychology?

Accepted Answer

It can lead people to make harmful decisions based on unsupported claims.
