- Q1Ruth and Debbie are identical twins who were raised by the same family. Vince and Frankie are identical twins who were separated at birth and raised by different families. According to research on the heritability of personality traits, Ruth's and Debbie's personalities are statisticallyless likely to match on the personality dimensions of openness and neuroticism than are Vince and Frankie but not on other personality dimensionsmore likely to be similar to one another than are Vince’s and Frankie’s personalitiesless likely to match on the personality dimensions of agreeableness and extraversion than are Vince and Frankie but not on other personality dimensionsmore likely to be dissimilar to one another than are Vince’s and Frankie’s personalitieslikely to be as similar and dissimilar to one another as are Vince’s and Frankie’s personalities30s
- Q2Johnny often hits his brother even though his brother does not do anything to antagonize him. Johnny’s aggression is most likely due to a combination ofhis genetic makeup, the fact that aggression can be evolutionarily adaptive, and a lack of neuroplasticityhis genetic makeup, the environment he grew up in, and the fact that aggression can be evolutionarily adaptivethe environment he grew up in, developmental delays, and the fact that aggression can be evolutionarily adaptivedevelopmental delays, the fact that aggression can be evolutionarily adaptive, and a lack of neuroplasticityhis genetic makeup, developmental delays, and a lack of neuroplasticity30s
- Q3Madeline has previously been diagnosed with major depressive disorder. She has an identical twin sister, Josephine, and a nonidentical sister, Abigail. Neither of Madeline’s sisters have previously been diagnosed with major depressive disorder. Which of the following statements is true of Madeline’s sisters?Neither sister is likely to be diagnosed with major depressive disorder because it is rare for family members to be diagnosed with the same disorder.Josephine is less likely to be diagnosed with major depressive disorder than Abigail in response to a stressful or traumatic event.Because their sister has been diagnosed, it is highly likely that both sisters will be diagnosed with major depressive disorder at some point in their lives.The sisters are equally likely to be diagnosed with major depressive disorder in response to a stressful or traumatic event.Josephine is more likely to be diagnosed with major depressive disorder than Abigail in response to a stressful or traumatic event.30s
- Q4Which hormone is released when a person is under stress?oxytocintestosteroneestrogenprogesteronecortisol30s
- Q5A person whose body is not producing enough testosterone is most likely to exhibitmemory lossoverly aggressive behaviorfatigueincreased hungerincreased thirst30s
- Q6The hormone most associated with the fight or flight response istestosteroneestrogenoxytocindopamineepinephrine30s
- Q7A neuron sends a signal along itsneurotransmitternucleusaxonoptic chiasmdendrite30s
- Q8The medulla oblongata is a part of thebrain stemcerebellumcorpus callosumprefrontal cortexoccipital lobe30s
- Q9The fatty casing that helps speed up the neural transmissions of a neuron is called thecorpus callosumsomamedullamyelin sheathcerebrum30s
- Q10Which of the following describes what happens when a neuron sends a signal?The neuron goes from being negatively charged to being positively charged, and then it remains at that level until it fires again. The magnitude of the positive charge varies depending on the strength of the input signal it receives.The neuron goes from being negatively charged to briefly being positively charged, and finally returns to being negatively charged again. The magnitude of the negative charge is fixed regardless of the strength of the input signal it receives.The neuron goes from being positively charged to briefly being negatively charged, and finally returns to being positively charged again. The magnitude of the negative charge is fixed regardless of the strength of the input signal it receives.The neuron goes from being positively charged to briefly being negatively charged, and finally returns to being positively charged again. The magnitude of the negative charge varies depending on the strength of the input signal it receives.The neuron goes from being negatively charged to briefly being positively charged, and finally returns to being negatively charged again. The magnitude of the positive charge varies depending on the strength of the input signal it receives.30s
- Q11If a body does not have enough potassium, how might that affect neuronal firing?The neurons will struggle to fire because potassium binds to receptors and inhibits neuronal firing.The neurons will fire too easily because there will not be enough positively charged ions to maintain a positively charged resting state.The neurons will struggle to fire because there will not be enough negatively charged ions to trigger the firing of the neuron.The neurons will fire too easily because there will not be enough negatively charged ions to maintain a negatively charged resting state.The neurons will struggle to fire because there will not be enough positively charged ions to trigger the firing of the neuron.30s
- Q12At a synapse, neurotransmitters released by the sending neuron do which of the following?They pass through channels into the receiving neuron.They bind to ions in the synapse, which creates a chemical reaction that causes the receiving neuron to fire.They combine with neurotransmitters released by the receiving neuron.They bind to receptors at the receiving neuron, which opens ion channels.They combine with neurotransmitters released by other sending neurons.30s
- Q13Antagonists function bymimicking neurotransmitters that bind to neural receptors to cause neural firingprompting the production of neurotransmittersstrengthening the connections between neuronsraising the threshold at which the neuron will fireblocking receptors to prevent other neurotransmitters from binding to the neural receptors30s
- Q14A drug that is used to treat seizures functions by preventing inhibitory neurotransmitters from returning to the presynaptic neuron. This slows the rate of neurons firing by increasing the amount of the inhibitory neurotransmitter in the synapse. The drug is most likely to be classified as ahallucinogenbeta blockerselective serotonin reuptake inhibitor (SSRI)stimulantGABA reuptake inhibitor (GRI)30s
- Q15What effect do agonists have?They increase the likelihood that a postsynaptic neuron will fire.They decrease the likelihood that a person will get a good night’s sleep.They lead to a decreased sex drive.They stimulate the gastric system, leading to increased hunger.They decrease the likelihood that a postsynaptic neuron will fire.30s
