s about "The Complete IB Psychology Biological Approach Course 2026: From Zero to Expert!" for "IB Diploma Psychology Mastery Hub: The Industry Foundation": Question: Within the context of the IB Psychology Biological Approach, which neuroimaging technique is MOST suitable for investigating the rapid, millisecond-level temporal resolution of neural activity during a cognitive task, while also acknowledging its limitations in spatial precision for pinpointing exact neuronal clusters?
Positron Emission Tomography (PET)
Functional Magnetic Resonance Imaging (fMRI)
Diffusion Tensor Imaging (DTI)
Electroencephalography (EEG)
Q2Domain Verified
A study within the IB Psychology Biological Approach aims to explore the causal relationship between the activation of the amygdala and fear conditioning. Which experimental manipulation would provide the STRONGEST evidence for causality, moving beyond mere correlation?
Correlating self-reported fear levels with amygdala volume in a sample of individuals with and without phobias.
Observing a significant positive correlation between amygdala activation (measured by fMRI) and fear responses in participants exposed to phobic stimuli.
Administering a pharmacological agent that selectively enhances amygdala activity and observing an increase in conditioned fear responses.
Utilizing transcranial magnetic stimulation (TMS) to temporarily inhibit amygdala activity and observing a decrease in conditioned fear responses.
Q3Domain Verified
Consider the IB Psychology Biological Approach's exploration of neurotransmitters and their influence on behavior. If a researcher hypothesizes that increased dopamine levels are responsible for enhanced reward-seeking behavior, which of the following experimental designs would best isolate dopamine's specific role, controlling for potential confounding variables related to other neurotransmitter systems?
Administering a dopamine antagonist and observing a reduction in reward-seeking behavior, while also measuring serotonin and norepinephrine levels to ensure they remain stable.
Measuring dopamine levels in participants who spontaneously engage in high levels of reward-seeking behavior compared to those who do not.
Correlating dopamine receptor density with self-reported motivation for rewards.
Administering a dopamine agonist and a serotonin antagonist simultaneously and observing changes in reward-seeking behavior.
