Researchers have found a positive correlation between parents spanking their children and their children being aggressive. Iddo believes that a 3rd variablemay be responsible for this relationship. Which of the following would support Iddo's idea? Spanking causes children to be more aggressive. Aggressive children are spanked more Spanking children causes them to be upset which makes them more aggressive. Stress in the household causes parents to spank more often and also causes kids to be more aggressive

Aggressive children are spanked more -?

In an experiment, why is a confounding variable a problem? It makes the results difficult to interpret It replaces the dependent variable It replaces the independent variable It creates a participant expectancy effect

It makes the results difficult to interpret

Match the brain region to it's function Frontal cortex- Temporal lobe-

Sam hypothesized that caffeine makes people more talkative. He ran a research study where he randomly assigned participants into one of two groups. One group of participants drank a caffeinated beverage. The other group drank the same beverage without caffeine. Participants were not told about the caffeine. Sam was careful not to indicate anything about caffeine levels when he gave out the drinks. Indicate which of the following is true (There are TWO correct responses) Sam is conducting a correlational study Sam should be wary of the directionality problem Sam will compare the mean talkativeness scores for the caffeine group with the mean talkativeness scores in the no caffeine group. Sam is blind to the experimental design If Sam gets statistically significant results confirming his hypothesis, his data will suggest that changes in caffeine level cause changes in talkativeness

Sam will compare the mean talkativeness scores for the caffeine group with the mean talkativeness scores in the no caffeine group. If Sam gets statistically significant results confirming his hypothesis, his data will suggest that changes in caffeine level cause changes in talkativeness

Which of the following is true of confounding variables (2 correct answers) They make it impossible to measure the dependent variable They change along with the independent variable They make it impossible to determine if the independent variable caused the change in the dependent variable.. They change along with the dependent variable.

They make it impossible to determine if the independent variable caused the change in the dependent variable. They change along with the independent variable

If the sensory receptors located in your thumb in your right hand did not function at all, what might the consequence be? Check all that could apply. (Hint: there are 2 correct answers) You would lose your sense of touch in your right thumb.. Due to plasticity, the sensory region for the thumb in the sensory region of the brain may eventually shift to respond to the face, and you might feel a touch on your thumb when your face was touched. You would not be able to move your right thumb. Due to plasticity the motor area for the thumb would instantly compensate for the lost sensory function and you would never notice any deficit.

What kind of data is best represented in a scatter plot? experimental case study double blind study correlational

correlational

Which of the following can ONLY be studied with a correlational approach (not an experimental approach). Check all that apply. (There are TWO correct responses) testing the effectiveness of a specific memory strategy for recalling vocabulary words examining the relationship between gender and life satisfaction examining the effect of poverty on school attendance looking at video game play to see whether different types of rewards impact strategy selection

examining the relationship between gender and life satisfaction examining the effect of poverty on school attendance

Phineas Gage lost a section of his brain when a tamping iron shot through his head. Surprisingly, he recovered and was able to perform most tasks. However, he changed as a person. Among other impairments, he had a great deal of trouble with planning. Also, his emotional reactions were altered. He no longer registered the importance and relevance of frightening or otherwise emotionally important stimuli. The tamping iron went through his frontal cortex (related to planning) and damaged the connection between this area and the amygdala (a subcortical area related to emotion).

frontal amygdala

In the Clever Hans example, whether or not people in the audience knew the answer to the questions is a(n) [ Select ] ["dependent", "correlational", "independent"] variable and Hans' responses to the questions is a(n) [ Select ] ["correlational", "independent", "dependent"] variable.

independent dependent

Which of the following is true of an agonist? it never leads to an action potential in the postsynaptic neuron it has no impact on the firing rate of the postsynaptic neuron It always leads to an action potential in the post synaptic neuron it sometimes leads to an action potential in the post synaptic neuron

it sometimes leads to an action potential in the post synaptic neuron

Neurotransmitter Q opens up Cl- ion channels on the postsynaptic neuron. If lots of neurotransmitter Q (and no other neurotransmitter) is released into the synapse what will happen in the postsynaptic neuron? it will fire an action potential it will block the neurotransmitter it will hyperpolarize it will depolarize

it will hyperpolarize

Imagine that you stubbed your toe, shouted out "Ow!" and hopped away in pain. The [ Select ] ["temporal lobe", "frontal lobe", "occipital lobe", "parietal lobe"] would be involved with the feeling of pain and the [ Select ] ["temporal lobe", "occipital lobe", "frontal lobe", "parietal lobe"] would be involved when you hopped away.

Tony is conducting a research study using the PSYC 1001 experiment pool. If you participate in his study, he will use random assignment to put you in either the "music" or "no music" group.

random assignment

When a person enters the fight or flight mode, which system becomes active? peripheral nervous system central nervous system sympathetic nervous system parasympathetic nervous system

sympathetic nervous system

In some cases psychology research is done with animals rather than humans. When conducting animal research, the researcher must consider the health and well-being of the animal participants .

the health and well-being of the animal participants

Which part of the neural communication process uses the most energy (ATP)? binding of neurotransmitters to receptors the sodium-potassium pump sodium passing through open ion channels along its concentration gradient release of neurotransmitters

the sodium-potassium pump
