What is an independent variable in an experimental study?
A variable that confounds the results
A variable that remains constant throughout the study
A variable that is manipulated by the researcher
A variable that is measured but not manipulated
The independent variable is manipulated by the researcher to observe its effect on the dependent variable. This allows the experiment to assess cause and effect relationships.
Which brain structure is primarily responsible for regulating balance and coordination?
Amygdala
Occipital lobe
Hypothalamus
Cerebellum
The cerebellum is responsible for fine-tuning motor activities and maintaining balance and posture. It plays a key role in coordinating movement.
What is the purpose of using a control group in an experiment?
To eliminate the need for random assignment
To provide extra experimental manipulation
To serve as a baseline for comparison
To introduce confounding variables
A control group provides a baseline by which the effects of the independent variable can be measured in the experimental group. This comparison helps confirm that observed changes are due to the manipulation.
Which method involves studying behavior in its natural environment without interference?
Naturalistic observation
Case study
Survey
Experiment
Naturalistic observation involves watching subjects in their natural settings without any experimental manipulation. This method minimizes artificial influences that could alter behavior.
In psychological research, informed consent refers to:
Participants paying for the study
Researchers deciding on behalf of participants
Researchers altering procedures without permission
Participants agreeing to take part after fully understanding the procedures
Informed consent ensures that participants have a clear understanding of what the research entails before agreeing to participate. This ethical practice protects participants' rights and wellbeing.
Medium
Which research design is best suited to establish cause-and-effect relationships?
Case study
Experimental design
Survey research
Correlational design
Experimental design allows researchers to manipulate the independent variable and directly measure its effect on the dependent variable. This controlled approach is vital for establishing causal relationships.
What does a double-blind study ensure in research?
That the study is conducted in two different locations
That neither participants nor experimenters know who is receiving the treatment
That participants receive double doses of the treatment
That the study utilizes both qualitative and quantitative methods
A double-blind study design is used to prevent both participant and experimenter biases that could affect the study's results. By keeping both parties unaware of group assignments, the study's objectivity is maintained.
Which neurotransmitter is commonly associated with regulating mood?
Glutamate
Serotonin
GABA
Acetylcholine
Serotonin plays a significant role in mood regulation and has been linked to conditions such as depression. Understanding its function is essential in the study of affective disorders.
Which of the following is an important ethical procedure after an experiment involving deception?
Recording false data
Withholding the true purpose from participants permanently
Debriefing the participants
Extending the experiment without consent
Debriefing is critical following studies that involve deception so that participants understand the true nature of the research. This practice helps alleviate potential negative effects and reinforces ethical standards.
Which imaging technique is known for its high spatial resolution in brain studies?
fMRI
CT scan
Ultrasound
EEG
fMRI offers high spatial resolution, making it ideal for pinpointing active brain regions during various tasks. Although EEG provides excellent temporal resolution, it lacks the spatial detail that fMRI delivers.
What is the primary role of the limbic system in the brain?
Controlling motor coordination
Processing visual information
Managing language production
Regulating emotions and memory
The limbic system, which includes structures such as the amygdala and hippocampus, is central to processing emotions and forming memories. Its effective functioning is crucial for both emotional regulation and learning.
In research, what is a confounding variable?
The variable that is purposely manipulated
A variable that confirms the hypothesis
The outcome variable measured by the study
An extraneous factor that unintentionally affects the dependent variable
A confounding variable is an uncontrolled factor that can influence the dependent variable, potentially skewing the results of the experiment. Recognizing and controlling for these variables is essential for valid research outcomes.
Which term refers to a data point that significantly deviates from other observations in a dataset?
Mean
Outlier
Mode
Median
An outlier is a data point that diverges significantly from the other values in a dataset. Identifying outliers is important because they can greatly influence statistical analyses and interpretations.
What is the primary goal of operationalizing variables in psychological research?
To increase the sample size
To define variables in measurable terms
To generate qualitative data
To eliminate the need for statistical analysis
Operationalizing variables involves defining abstract concepts so that they can be measured or manipulated in a study. This process is key to testing hypotheses and ensuring that the data collected is meaningful.
Which scale of measurement involves ranking items without assuming equal intervals between ranks?
Ordinal scale
Interval scale
Nominal scale
Ratio scale
The ordinal scale ranks items in order, but the differences between ranks are not necessarily equal. This property distinguishes it from interval and ratio scales, which assume consistent intervals between measurements.
Hard
In a longitudinal study investigating cognitive decline, which advantage is most prominent compared to a cross-sectional study?
Immediate results without time delay
Easier data collection and analysis
Ability to track changes over time within the same individuals
Elimination of participant dropout effects
Longitudinal studies excel at observing changes over time in the same sample, offering insights into developmental trends or cognitive decline. This design provides a dynamic picture that cross-sectional studies, which capture a single moment, cannot deliver.
How does random assignment enhance the internal validity of an experiment?
By allowing the use of correlational methods
By standardizing the dependent variable
By increasing the sample size automatically
By ensuring that all participant characteristics are evenly distributed across groups
Random assignment distributes potential confounding variables evenly among groups, enhancing the experiment's internal validity. This process increases the likelihood that observed effects are due to the experimental manipulation rather than preexisting differences.
Which research method is best suited for exploring rare phenomena that are difficult to replicate?
Survey research
Observational study
Case study
Experimental design
Case studies provide an in-depth analysis of rare or unique phenomena that may not be easily studied through other methods. While they lack generalizability, they are invaluable for generating hypotheses and gaining detailed insights.
Which brain imaging technique combines both structural and functional information and has been increasingly used in cognitive neuroscience?
PET/CT scan
X-ray imaging
EEG
MRI
A PET/CT scan integrates the metabolic information of PET with the anatomical details of CT, providing a comprehensive view of brain activity and structure. This hybrid approach is especially useful in diagnosing complex neurological conditions.
In psychological research, what is the primary drawback of relying solely on correlational studies to infer causality?
Correlation does not imply causation, so the relationship might be influenced by a third variable
They require manipulation of variables
Correlational studies are usually more expensive
They do not require statistical analysis
The main limitation of correlational studies is that they only reveal associations between variables, not direct cause-and-effect relationships. A third variable might be responsible for the observed relationship, which is why experimental designs are needed to infer causality.

AP Psych Unit 2 Progress Check & Review Cheat Sheet

  1. Neuron Structure & Function - Our brain cells, or neurons, are like tiny communication hubs, sending electric signals through dendrites and axons to keep you thinking, feeling, and moving. The myelin sheath acts like insulation on a wire, speeding up these messages so your reactions feel lightning-fast. Course Notes
  2. Limbic System Roles - Dive into your brain's emotional control center: the limbic system! Structures like the amygdala act as your fear alarm, the hippocampus files away your memories, and the hypothalamus keeps your body's basic needs in check. Survive AP Psychology
  3. Cerebral Cortex Lobes - The cerebral cortex is divided into four lobes, each with its own VIP duties: the frontal lobe plans and reasons, the parietal lobe processes touch, the occipital lobe interprets vision, and the temporal lobe handles sound and memory. Understanding these zones helps you map brain function to everyday life. Survive AP Psychology
  4. Assimilation & Accommodation - When you learn, your brain either tucks new info into existing mental "folders" (assimilation) or reshuffles those folders to fit fresh ideas (accommodation). Jean Piaget's dynamic duo explains how we grow smarter and stay flexible thinkers. Knowt
  5. Problem-Solving Strategies - Algorithms are step-by-step recipes that guarantee a solution, while heuristics are mental shortcuts that speed things up - sometimes at the cost of accuracy. Beware mental sets: once you find one way to solve a problem, you might get stuck repeating it! Knowt
  6. Memory Encoding Types - Encoding is like taking notes in your brain: visual encoding sketches pictures, acoustic encoding records sounds, and semantic encoding focuses on meaning. The richer the note, the better your recall later on. Knowt
  7. Random Assignment - In experiments, random assignment is like shuffling a deck of cards - everyone has an equal shot at being in any group. This trick helps control confounding variables and keeps your results airtight. Course Notes
  8. Placebo Effect - Believe it or not, expecting a treatment to work can produce real results - hello, placebo effect! That's why control groups are superheroes, protecting studies from misleading mind tricks. Course Notes
  9. Ethical Principles - Psychology research isn't just about brains; it's about people. Informed consent, debriefing, and confidentiality ensure participants stay safe, respected, and in the loop. Course Notes
  10. Statistical Significance - Statistical significance tells you whether your results are due to chance or a real effect. Understanding p-values and confidence levels is a must for interpreting data like a pro. Course Notes
