Which of the following statements describing Skinner's theory of operant conditioning is NOT true?
- A.
Rewards and punishments shape behavior
- B.
A behavior followed by a rewarding stimulus is likely to be repeated.
- C.
A behavior followed by a punishing stimulus is less likely to recur.
- D.
A behavior that is ignored will be repeated.
Correct Answer
D. A behavior that is ignored will be repeated.Explanation
Skinner's theory of operant conditioning states that a behavior followed by a rewarding stimulus is likely to be repeated, and a behavior followed by a punishing stimulus is less likely to recur. However, the statement that a behavior that is ignored will be repeated is not true according to Skinner's theory. In operant conditioning, behaviors that are not reinforced or rewarded tend to decrease and eventually extinguish over time.Rate this question:

Harry fights constantly with his parents. Bronfenbrenner would predict that Harry might have difficult related to his teacher because of a disruption in his.
- A.
Mesosystem
- B.
Exosystem
- C.
Chronosystem
- D.
Macrosystem.
Correct Answer
A. MesosystemExplanation
Bronfenbrenner's ecological systems theory suggests that the different systems in a person's environment interact and influence their development. The mesosystem refers to the connections between different microsystems, such as the interactions between family and school. In this case, Harry's constant fights with his parents indicate a disruption in his family microsystem. Bronfenbrenner would predict that this disruption could affect his relationship with his teacher, who is part of his school microsystem, leading to difficulties in that area. Therefore, the correct answer is mesosystem.Rate this question:

Which of the following statements about standardized tests is TRUE?
- A.
They assume that a person's behavior is consistent and stable
- B.
They do not provide any information about differences among people
- C.
They assume that people will perform differently depending on the setting of the test
- D.
They do not allow a person's performance to be compared with the performance of other people.
Correct Answer
A. They assume that a person's behavior is consistent and stableExplanation
Standardized tests assume that a person's behavior is consistent and stable. This means that the test assumes that an individual's performance on the test will be representative of their typical behavior and abilities. It assumes that a person's behavior and abilities will not significantly change from one testing situation to another. This assumption allows for the comparison of test scores among individuals and helps to establish a standardized measure of performance.Rate this question:

MRI uses -- to construct an image of the --
- A.
Radioactive glucose, brain
- B.
Electrical activity levels, heart
- C.
X-rays, brain
- D.
Radio waves, brain
Correct Answer
D. Radio waves, brainExplanation
MRI uses radio waves to construct an image of the brain. During an MRI scan, the patient is placed inside a strong magnetic field, which causes the protons in the body to align with the field. Radio waves are then applied, causing the protons to emit signals that are captured by the MRI machine. These signals are then processed to create detailed images of the brain, allowing doctors to diagnose various conditions and abnormalities.Rate this question:

- B.
Experimental design uses experimental groups only
- C.
All experiments involve at least one independent variable and one dependent variable
- D.
Experiments must demonstrate cause and effect.
Correct Answer
B. Experimental design uses experimental groups onlyExplanation
The given statement that "Experimental design uses experimental groups only" is not true. Experimental design actually uses both experimental groups and control groups. The experimental group is exposed to the independent variable being tested, while the control group is not. This allows researchers to compare the effects of the independent variable and determine causation. Therefore, the correct answer is that experimental design uses both experimental and control groups.Rate this question:

- B.
People may be too relaxed in a laboratory setting
- C.
People who are willing to come to a laboratory might not be representative of the general population
- D.
People behave more naturally when they are away from the stresses of the "real world."
Correct Answer
C. People who are willing to come to a laboratory might not be representative of the general populationExplanation
Conducting observational research in a laboratory may have the drawback that the people who are willing to participate in such studies might not be representative of the general population. This is because individuals who are willing to come to a laboratory setting may have certain characteristics or motivations that make them different from the average person. Therefore, the findings from the study may not be applicable or generalizable to the broader population.Rate this question:

Denise argues that early experiences are more important; Barbara believes that both early and later experiences are important. Denise's view is consistent --, while Barbara's view would be supported by --.
- A.
Freud, Erikson
- B.
Eirkson, Blos
- C.
Blos, Erikson
- D.
Erikson, Freud
Correct Answer
A. Freud, EriksonExplanation
Denise argues that early experiences are more important, which aligns with Freud's theory of psychosexual development. Freud believed that early childhood experiences, particularly those related to the development of the id, ego, and superego, have a significant impact on an individual's personality. On the other hand, Barbara believes that both early and later experiences are important, which is consistent with Erikson's theory of psychosocial development. Erikson proposed that individuals go through various stages of development throughout their lives, and each stage presents unique challenges and opportunities for growth. Therefore, Barbara's view would be supported by Erikson's theory.Rate this question:

- D.
Sickle-cell anemia
Correct Answer
D. Sickle-cell anemiaExplanation
Sickle-cell anemia is a blood disorder that causes the body to produce abnormal red blood cells. These cells are shaped like sickles or crescents, which can get stuck in blood vessels and block the flow of oxygen. This leads to a reduced oxygen supply to the body's tissues and organs, causing symptoms such as joint swelling and potentially leading to heart and kidney failure. Treatment for sickle-cell anemia typically involves managing symptoms and complications through medications like penicillin, pain medication, and antibiotics, as well as blood transfusions. The mention of the Baby HUG study suggests that there is ongoing research to find better treatment options for this genetic disorder in the future.Rate this question:

B. Over many generationsExplanation
Evolution takes place over many generations because it is a gradual process that occurs through the accumulation of small genetic changes over time. These changes are passed on from one generation to the next, resulting in the gradual transformation of species. It is not an immediate process, as significant changes in a species' characteristics and traits require multiple generations to occur. Therefore, evolution is a slow and gradual process that unfolds over many generations.Rate this question:

A fertilized human egg cannot grow into a crocodile, duck, or fish specifically because of:
- A.
Natural selection
- B.
Adaptive behavior
- C.
Evolution
- D.
Genetic code
Correct Answer
D. Genetic codeExplanation
A fertilized human egg cannot grow into a crocodile, duck, or fish specifically because of the genetic code. The genetic code of a human is different from that of a crocodile, duck, or fish. Each species has its own unique set of genes that determine their physical characteristics and development. These genes are passed down from parents to offspring and dictate the traits that an organism will have. Therefore, the genetic code plays a crucial role in determining the specific species that an organism will develop into.Rate this question:

Combining the genes of two parents in offspring is one of the ways in which -- increases in the population, which is valuable for a species because it provides more characteristics for natural selection to operate on.
- A.
Gender variability
- B.
The number of males
- C.
Genetic variability
- D.
The number of females
Correct Answer
C. Genetic variabilityExplanation
Combining the genes of two parents in offspring increases genetic variability in the population. This is valuable for a species because it provides more characteristics for natural selection to operate on. Genetic variability allows for a wider range of traits and adaptations, increasing the chances of survival and reproduction in changing environments. It also helps prevent the accumulation of harmful mutations and promotes the overall health and resilience of the population.Rate this question:

Most individuals who have X-linked diseases are...
- A.
Females
- B.
Intersex
- C.
Hemopheliacs
- D.
Males
Correct Answer
D. MalesExplanation
The correct answer is males. X-linked diseases are caused by mutations in genes located on the X chromosome. Since males have one X chromosome and one Y chromosome, they only need to inherit one copy of the mutated gene to develop the disease. In contrast, females have two X chromosomes, so they would need to inherit two copies of the mutated gene to be affected by the disease. Therefore, males are more commonly affected by X-linked diseases.Rate this question:

Which of the following best exemplifies an evocative genotype-environment correlation?
- A.
Parents suggest music lessons for their musically talented children.
- B.
A nervous adolescent displays anxiety at school
- C.
A highschool student bound for an agricultural college signs up for courses in plant biology
- D.
Musical parents buy a piano for their children.
Correct Answer
A. Parents suggest music lessons for their musically talented children.Explanation
The correct answer is "Parents suggest music lessons for their musically talented children." This exemplifies an evocative genotype-environment correlation because the children's musical talent (genotype) elicits a specific environment (music lessons) that supports and enhances their talent. The parents are responding to the children's inherent abilities and providing an environment that fosters their musical development. This is an example of how a person's genetic predispositions can shape their environment.Rate this question:

Researchers are exploring the potential for using NIPD to diagnose a baby's sex, as early as five weeks after conception, and Down Syndrome. However, being able to detect an offspring's sex and various diseases and defects so early through NIPD raises ethical concerns about...
- A.
A nature versus nurture
- B.
Physical and psychological consequences for children
- C.
Couples' motivation to terminate a pregnancy
- D.
Causing mental retardation in fetuses.
Correct Answer
C. Couples' motivation to terminate a pregnancyExplanation
The potential to diagnose a baby's sex and various diseases and defects through NIPD raises ethical concerns about couples' motivation to terminate a pregnancy. This means that if couples are able to find out early on that their baby may have a certain condition or is of a certain sex, they may be more inclined to consider terminating the pregnancy based on these factors. This raises questions about the value placed on certain traits or conditions, and the potential impact on the overall well-being and diversity of society.Rate this question:

Which of the following statements is true regarding the differences between outcomes for adopted and nonadopted children?
- A.
Adoptees were no more likely to be using mental health serices than their nonadopted counterparts.
- B.
Children who are adopted very early in their lives are more likely to have positive outcomes than children adopted later in life
- C.
Nonadopted children are likely to experience more school-related problems than adopted children
- D.
Adopted adolescents were more likely to be withdrawn.
Correct Answer
B. Children who are adopted very early in their lives are more likely to have positive outcomes than children adopted later in lifeExplanation
Children who are adopted very early in their lives are more likely to have positive outcomes than children adopted later in life. This suggests that the timing of adoption plays a significant role in the well-being of adopted children. Early adoption allows children to form secure attachments with their adoptive parents, which can positively impact their emotional and social development. On the other hand, children adopted later in life may have experienced more instability and trauma, which could lead to greater challenges in their overall outcomes.Rate this question:
