A researcher wants to study the effect of a new medication on anxiety levels. Participants are randomly assigned to either receive the medication or a placebo. What is the independent variable in this study?
The new medication
✓
Anxiety levels
Participant age
Random assignment
Correct Answer
The new medication
The independent variable is the factor that is manipulated by the experimenter. Anxiety levels are the dependent variable, which is measured. Random assignment is a control method. Participant age is a demographic variable that might be controlled but is not the independent variable.
Question 2
Which of the following research methods allows researchers to determine cause-and-effect relationships between variables?
Case study
Experimental research
✓
Naturalistic observation
Correlational study
Correct Answer
Experimental research
Experimental research involves manipulating an independent variable and measuring its effect on a dependent variable, allowing for cause-and-effect conclusions. Correlational studies identify relationships but not causality. Case studies provide in-depth information about one or a few individuals but lack generalizability. Naturalistic observation involves observing behavior in its natural setting without intervention, thus not establishing causality.
Question 3
Before participating in a psychological study, individuals must be informed about the study's purpose, risks, and their right to withdraw. This ethical principle is known as:
Deception
Debriefing
Confidentiality
Informed consent
✓
Correct Answer
Informed consent
Informed consent ensures participants understand the study and voluntarily agree to participate. Debriefing occurs after the study to explain its true purpose and any deception. Confidentiality protects participants' personal information. Deception is sometimes used in research but must be justified and followed by debriefing.
Question 4
A negative correlation between two variables indicates that:
One variable causes a decrease in the other.
There is no relationship between the variables.
As one variable increases, the other variable decreases.
✓
As one variable increases, the other variable also increases.
Correct Answer
As one variable increases, the other variable decreases.
A negative correlation means that as one variable's value goes up, the other variable's value tends to go down. When both variables increase together, it is a positive correlation. No relationship indicates a correlation close to zero. Correlation does not imply causation.
Question 5
In Pavlov's classical conditioning experiment, the salivation to the sound of the bell after conditioning is the:
Conditioned response (CR)
✓
Unconditioned stimulus (UCS)
Conditioned stimulus (CS)
Unconditioned response (UCR)
Correct Answer
Conditioned response (CR)
The conditioned response (CR) is the learned reaction to the previously neutral stimulus (the bell). The unconditioned stimulus (UCS) is the food, which naturally elicits salivation. The unconditioned response (UCR) is the natural salivation to the food. The conditioned stimulus (CS) is the bell, which becomes associated with the food.
Question 6
A child cleans their room to avoid being grounded. This is an example of:
Positive reinforcement
Negative punishment
Positive punishment
Negative reinforcement
✓
Correct Answer
Negative reinforcement
Negative reinforcement involves the removal of an aversive stimulus (being grounded) to increase the likelihood of a behavior (cleaning the room). Positive reinforcement adds a desirable stimulus to increase behavior. Positive punishment adds an aversive stimulus to decrease behavior. Negative punishment removes a desirable stimulus to decrease behavior.
Question 7
What happens during extinction in classical conditioning?
The conditioned stimulus is repeatedly presented without the unconditioned stimulus.
✓
The unconditioned stimulus is no longer effective in eliciting a response.
The conditioned stimulus is paired with a new unconditioned stimulus.
The conditioned response reappears after a rest period.
Correct Answer
The conditioned stimulus is repeatedly presented without the unconditioned stimulus.
Extinction occurs when the conditioned stimulus (e.g., bell) is repeatedly presented without the unconditioned stimulus (e.g., food), leading to a decrease and eventual disappearance of the conditioned response. The reappearance after a rest period is spontaneous recovery. Pairing with a new UCS is higher-order conditioning. The UCS always elicits the UCR.
Question 8
Which schedule of reinforcement produces a high, steady rate of responding because reinforcement is unpredictable?
Fixed-interval
Fixed-ratio
Variable-ratio
✓
Variable-interval
Correct Answer
Variable-ratio
A variable-ratio schedule provides reinforcement after an unpredictable number of responses, leading to high and steady rates of behavior (e.g., gambling). Fixed-ratio schedules produce high response rates with a pause after reinforcement. Fixed-interval schedules produce a scallop-shaped response pattern. Variable-interval schedules produce a slow, steady rate of responding.
Question 9
Which memory system holds information for only a few seconds or less, such as the fleeting image of a lightning flash?
Long-term memory
Working memory
Sensory memory
✓
Short-term memory
Correct Answer
Sensory memory
Sensory memory is the initial, briefest stage of memory that holds raw sensory information for a very short duration. Short-term memory holds a limited amount of information for a slightly longer period. Long-term memory has a vast capacity and duration. Working memory is a component of short-term memory involved in active manipulation of information.
Question 10
Remembering how to ride a bicycle, even after many years, is an example of which type of long-term memory?
Semantic memory
Procedural memory
✓
Flashbulb memory
Episodic memory
Correct Answer
Procedural memory
Procedural memory is a type of implicit long-term memory that stores information about how to perform skills and actions. Episodic memory stores personal experiences and events. Semantic memory stores general facts and knowledge. Flashbulb memory is a vivid, detailed memory of a significant event.
Question 11
The process by which information is initially recorded into a form usable by memory is called:
Consolidation
Retrieval
Storage
Encoding
✓
Correct Answer
Encoding
Encoding is the initial process of transforming sensory information into a form that can be stored in memory. Storage is the process of maintaining information in memory over time. Retrieval is the process of locating and recovering information from memory. Consolidation is the process by which a memory becomes stable in the brain.
Question 12
Forgetting information because new information interferes with the ability to recall old information is known as:
Proactive interference
Retrieval failure
Decay theory
Retroactive interference
✓
Correct Answer
Retroactive interference
Retroactive interference occurs when new learning impairs the recall of previously learned information. Proactive interference occurs when old learning interferes with the recall of new information. Decay theory suggests memories fade over time if not used. Retrieval failure occurs when information is in memory but cannot be accessed.
Question 13
According to Jean Piaget's theory of cognitive development, children first develop object permanence during the:
Sensorimotor stage
✓
Concrete operational stage
Formal operational stage
Preoperational stage
Correct Answer
Sensorimotor stage
Object permanence, the understanding that objects continue to exist even when out of sight, is a key cognitive milestone achieved during the sensorimotor stage (birth to 2 years). The preoperational stage involves symbolic thought but lacks logical reasoning. The concrete operational stage involves logical thought about concrete events. The formal operational stage involves abstract reasoning.
Question 14
Erik Erikson's theory of psychosocial development emphasizes that individuals face specific developmental tasks or 'crises' at different stages of life. The primary crisis during adolescence is:
Intimacy vs. Isolation
Identity vs. Role Confusion
✓
Autonomy vs. Shame and Doubt
Trust vs. Mistrust
Correct Answer
Identity vs. Role Confusion
During adolescence (roughly 12-18 years), individuals strive to form a sense of self and personal identity, leading to the crisis of Identity vs. Role Confusion. Trust vs. Mistrust is the crisis of infancy. Autonomy vs. Shame and Doubt occurs in early childhood. Intimacy vs. Isolation is the crisis of early adulthood.
Question 15
A child who is distressed when their parent leaves but is easily comforted upon their return likely demonstrates which attachment style?
Ambivalent attachment
Disorganized attachment
Avoidant attachment
Secure attachment
✓
Correct Answer
Secure attachment
Securely attached children show distress when separated from their caregiver but are readily comforted upon reunion, indicating a healthy attachment bond. Avoidant children show little distress upon separation and avoid the caregiver upon reunion. Ambivalent children are highly distressed by separation and are not easily comforted upon reunion, showing resistance. Disorganized attachment involves inconsistent and often contradictory behaviors.
Question 16
The debate about the relative influence of genetic inheritance and environmental experiences on development is known as the:
Continuity vs. Discontinuity debate
Critical periods debate
Nature vs. Nurture debate
✓
Stability vs. Change debate
Correct Answer
Nature vs. Nurture debate
The nature vs. nurture debate addresses the extent to which genetic inheritance (nature) and environmental factors (nurture) influence development. Continuity vs. Discontinuity refers to whether development is a gradual process or occurs in distinct stages. Stability vs. Change questions whether personality traits remain consistent or change over time. Critical periods refer to specific times when certain experiences are necessary for development.
Question 17
Which psychological perspective focuses on unconscious drives and conflicts, often stemming from early childhood experiences, to explain behavior?
Cognitive perspective
Psychodynamic perspective
✓
Behavioral perspective
Humanistic perspective
Correct Answer
Psychodynamic perspective
The psychodynamic perspective, originated by Sigmund Freud, emphasizes the influence of unconscious psychological processes and early childhood experiences on personality and behavior. The behavioral perspective focuses on observable behavior and learning. The cognitive perspective focuses on mental processes like thinking and memory. The humanistic perspective emphasizes free will and self-actualization.
Question 18
A psychologist who studies how people process, store, and retrieve information, and how these mental processes influence behavior, is working within which perspective?
Sociocultural perspective
Psychodynamic perspective
Cognitive perspective
✓
Biological perspective
Correct Answer
Cognitive perspective
The cognitive perspective focuses on mental processes such as perception, memory, problem-solving, and language. The biological perspective examines the physiological basis of behavior. The sociocultural perspective considers the influence of social and cultural factors. The psychodynamic perspective emphasizes unconscious drives and conflicts.
Question 19
The humanistic perspective in psychology emphasizes:
Free will, self-actualization, and the inherent goodness of people.
✓
The role of observational learning and modeling.
The impact of societal norms and cultural values.
Unconscious conflicts and repressed desires.
Correct Answer
Free will, self-actualization, and the inherent goodness of people.
The humanistic perspective, with figures like Maslow and Rogers, emphasizes human potential, free will, and the drive towards self-actualization. Observational learning is associated with the social-cognitive perspective. Societal norms are central to the sociocultural perspective. Unconscious conflicts are a focus of the psychodynamic perspective.
Question 20
Which perspective would most likely explain abnormal behavior as a result of imbalances in neurotransmitters or structural brain abnormalities?
Cognitive perspective
Biological perspective
✓
Behavioral perspective
Psychodynamic perspective
Correct Answer
Biological perspective
The biological perspective explains behavior, including abnormal behavior, through physiological and neurological factors such as brain structures, neurotransmitters, and genetics. The behavioral perspective focuses on learned behaviors. The cognitive perspective focuses on maladaptive thought patterns. The psychodynamic perspective looks at unconscious conflicts.
