Test Questions Terms in this set (41)Which modern psychological perspective focuses on events in the body and brain, and their effects on behavior, emotions, and thought? biological After trauma to the head, Tim showed deficits in his abstract thinking, memory, planning and judgement. In what area of the cerebral cortex do you suspect damage? frontal lobe Coin-shaped electrodes are pasted onto Miranda's scalp, and they are connected by wire to a machine that translates the electrical energy from her brain into wavy lines on a moving piece of paper. From this description, it is evident that Miranda's brain is being studied by the use of: EEG Research has shown that height and weight are strongly correlated. One explanation is that they may both be effects of different levels of nutrition. This explanation is an example of what kind of correlational issue? third variable problem Which of the following statements about neurons is not true? Neurons either do or do not "fire." Stimulation of the dendrites does not always trigger "firing." Activation must exceed a threshold before the neuron begins to "fire." The intensity of the stimulus makes the neuron respond more intensely. Activation must exceed a threshold before the neuron begins to "fire." An experiment in which the true purpose is hidden from the researcher as well as the participant is called a: double-blind experiment According to some historical accounts, Phineas Gage experienced a dramatic personality change as a result of damage to his: frontal lobes The ethical principal of _______ means that research participants are given enough info about a study to make a reasonable decision about whether or not to participate. informed consent Today, the predominant approach to viewing and treating psychological problems is: biological When a person quickly determines the emotional importance of sensory information in order to decide whether or not to approach a person, the _______ is responsible for this function. amygdala A brief change in electrical voltage in the neuron in response to stimulation is called: action potential The cerebrum is divided into two separate halves that are connected by a large band of fibers are called: corpus callosum Michael Gazzaniga, the researcher involved in the "split brain studies," suggests that human beings try to interpret their individual actions in order to construct a world that makes sense, and that this interpreting function appears to occur in the ________ hemisphere. left A reliable source of measure is one that: tends to produce the same result whenever it's used to measure the same thing. tends to differentiate between accurate and inaccurate data. is also an accurate measure of an underlying property. tends to produce the same result whenever it's used to measure the same thing. A statement that attempts to predict or to account for a set of phenomena is called a/an: theory Which of the following regions is involved in the ability to make plans, think creatively, and take initiative? temporal lobes parietal lobes frontal lobes occipital lobes frontal lobes Some researchers argue that the only way to conduct research is through highly controlled, lab studies. Others argue that experimental procedures should resemble "real world" conditions. Essentially, these researchers are debating the importance of ____________. random selection vs. random sampling internal vs. external validity observational vs. correlational research empirical vs. scientific method internal vs. external validity The ________ receive information; the ___________ transmit information. axons; cell bodies axons; dendrites Subjects are randomly assigned to the experimental or control condition: to make sure the two groups are equivalent. to eliminate the placebo effect. to control for possible correlations between the independent and dependent variables. to control for experimenter effects. to make sure the two groups are equivalent. A cell that conducts electro-chemical signals and is the basic unit of the nervous system is called a: glial cell neuron The _______ lobe, which processes visual information, is located at the back of the cerebral cortex. frontal occipital A negative correlation means that: high values of one variable are associated with low values of the other. high values of one variable are associated with high values of the other. low values of one variable are associated with low values of the other. there is no relationship between the two variables. high values of one variable are associated with low values of the other. Mike wants to know how many licks it takes to get to the center of his all-day sucker. He tells his friends that "one full gyration of the tongue around the outer surface of the lollipop" is what constitutes a "lick." In an informal way, Mike is offering a(n): way to use casual observation to answer his question. way to eliminate the reactivity sometimes associated with observation. operational definition for the abstract properties he wants to measure. excuse for eating a lot of candy. operational definition for the abstract properties he wants to measure.

The underlying cerebrum is referred to as "white matter" because it contains mostly ________. myelinated axons; dendrites
cell bodies; myelinated axons The communication chemicals that actually cross the synaptic gap between axons and dendrites are: neurotransmitters Techniques such as meta-analysis are useful in psychology because: they help reduce unintended changes in subjects' behavior due to cues given by the experimenter. they allow for the careful study of behavior in schools, workplaces, and other natural contexts. they include subjects who are exposed to experimental conditions that do not include the independent variable. rarely does one study prove anything and this technique analyzes data from many studies. they include subjects who are exposed to experimental conditions that do not include the dependent variable. Dr. Stearns is studying what happens behaviorally when a brain area is temporarily inactivated. Which method is he most likely to be using? fMRIs TMS Which of the following regions contains the auditory cortex? temporal lobes temporal lobes Functional magnetic imaging (fMRI) directly measures the oxygen levels in the blood in the brain in order to examine the: virtual lesioning that occurs due to lack of O2. neural activity of the brain during a specific task. electrical activity of the brain. different functions of the brain's two hemispheres. neural activity of the brain during a specific task. Professor C. Cane wants to know if eating sweets for a bedtime snack makes children active. In here study, sweets before bedtime would be the: independent variable independent variable In general, the ________ hemisphere is in charge of the left side of the body and the ________ hemisphere is in charge of the right side of the body. left; right right; left An organized system of assumptions and principals that purports to explain a specified set of phenomena and their interrelationships is called a/an: hypothesis hypothesis After a stroke, a patient appears to be unable to respond to words spoken to her. The patient has no problem speaking, but she is not able to follow verbal directions. What is a likely explanation for these symptoms? damage to the auditory cortex damage to Wernicke's area In order to be useful, a test must be valid, that is, it must: produce the same results from one time to the next. compare results against established standards of performance. measure what it is designed to measure. predict other criteria of the trait in question. measure what it is designed to measure. Which structure controls the pituitary gland through chemical signals? hypothalamus The higher a mail monkey's level of the hormone testosterone, the more aggressive he is likely to be. This means that: testosterone causes aggression. testosterone and aggression are uncorrelated. testosterone and aggression are negatively correlated. testosterone and aggression are positively correlated. testosterone and aggression are positively correlated. If you list a set of scores from the lowest value to the highest, then take the middle value to indicate what is a typical score, you are using the: median Which of the following is true? Scientists should keep their research secret so others will not steal their ideas. It is a waste of time and money to replicate a study that has already been done. Disclosure of the details of a study is important to allow for replication by others. Research procedures, once patented, should be shared in order to increase profits. Disclosure of details of a study is important to allow for replication by others. A detailed description of a particular individual being studied or treated is called: a representative sample a case study
What is a limitation of correlational studies? Correlations tell us nothing about the relationship between two variables. A causal relationship can never be inferred. Correlations are not reliable or valid. Most of the time, statistical correlational analysis is too complicated to run. A causal relationship can never be inferred. Wilhelm randomly assigns participants to wo groups and compares the group that receives a treatment with the group that receives no treatment.

This response reflects which kind of love? 3 answers Which technique for investigating the function of brain regions is similar to Lesioning but has no ill effects?Brain Stimulation
The procedure of stimulating a specific area of the brain is much the same as in lesioning, but the much milder current in this research does no damage to the neurons. It does cause the neurons to react as if they had received a message. This is called electrical stimulation of the brain, or ESB.
What neurotransmitter affects neurons involved in muscle action arousal vigilance memory?Acetylcholine (ACh) is found throughout the nervous system, where it acts as either an excitatory or inhibitory neurotransmitter, both within the brain and between neurons and muscle cells. 2. Norepinephrine is involved in activation, vigilance, and mood regulation.
Which part of the brain is located at the base of the skull and looks like a stalk rising out of the spinal cord?The Brainstem lies at the base of the brain and the top of the spinal cord. The brainstem is the structure that connects the cerebrum of the brain to the spinal cord and cerebellum. It is composed of 3 sections in descending order: the midbrain, pons, and medulla oblongata.
