Exam 4 Psychology
1. What are substances, such as viruses and drugs, that can cause birth defects?
- A. Teratogens
- B. Placenta
- C. Parturition
- D. Androgens
Correct answer: A
Rationale: Teratogens are substances that can cause birth defects, especially if exposure occurs during critical periods of development. In this context, teratogens refer to external agents that can interfere with the development of the embryo or fetus, leading to structural or functional abnormalities. Choice B, Placenta, is incorrect as it is an organ that develops during pregnancy to provide nutrients and oxygen to the fetus and remove waste products. Choice C, Parturition, refers to the process of giving birth and is not related to substances that cause birth defects. Choice D, Androgens, are male sex hormones and are not associated with causing birth defects.
2. Sandy took part in the April 2013 Boston Marathon, where two bombs were detonated near the finish line, killing three spectators. For approximately 2 weeks after the marathon, Sandy was unable to sleep or concentrate and often found herself reliving the moment she heard the bombs explode. What disorder might Sandy be diagnosed with?
- A. Posttraumatic stress disorder
- B. Phobic disorder
- C. Panic disorder
- D. Acute stress disorder
Correct answer: A
Rationale: Sandy might be diagnosed with posttraumatic stress disorder (PTSD). PTSD typically develops after exposure to a traumatic event and is characterized by symptoms such as re-experiencing the event, avoidance of reminders of the event, negative changes in thoughts and mood, and heightened reactivity. While acute stress disorder can occur shortly after a traumatic event, the duration of symptoms in the scenario suggests a more prolonged impact, aligning with PTSD. Phobic disorder and panic disorder are not as closely related to the described symptoms as PTSD.
3. Who is credited with establishing psychology as a distinct scientific field, separate from other disciplines?
- A. G. Stanley Hall
- B. René Descartes
- C. William James
- D. Wilhelm Wundt
Correct answer: D
Rationale: Wilhelm Wundt is the correct answer as he is credited with establishing psychology as a distinct scientific field. Wundt founded the first laboratory dedicated to experimental psychology in 1879, which marked the beginning of psychology as a separate discipline. While the other individuals mentioned in the choices have made significant contributions to the field of psychology, Wilhelm Wundt is specifically known for his pioneering work in establishing psychology as a unique and independent discipline.
4. Normal human cells have ________
- A. twenty-two chromosome pairs and one pair of sex chromosomes.
- B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
- C. twenty-one chromosome pairs and two trisomy chromosome pairs.
- D. twenty-three chromosome pairs.
Correct answer: A
Rationale: Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This is the correct answer as it accurately describes the typical chromosome count in human cells. Choice B is incorrect because it mentions 'twenty-one trisomy chromosome pairs,' which is not characteristic of normal cells. Choice C is incorrect as it suggests having 'two trisomy chromosome pairs,' which is abnormal. Choice D is incorrect as it states 'twenty-three chromosome pairs,' which is not the standard count in normal human cells.
5. What is the term for the age of an unborn baby, usually dated from the first day of an expectant mother's last menstrual cycle?
- A. Mental age
- B. Chronological age
- C. Functional age
- D. Gestational age
Correct answer: D
Rationale: The correct answer is D, Gestational age. Gestational age is calculated from the first day of the expectant mother's last menstrual cycle, providing an estimate of how far along the pregnancy is. Mental age (choice A), refers to an individual's level of cognitive functioning in relation to others of the same age group. Chronological age (choice B) is a person's actual age in years. Functional age (choice C) refers to how well a person is able to perform various activities compared to their chronological age.
