Biological Foundations of Behavior(16)
What neurotransmitter is primarily associated with pleasure?
Dopamine. It plays a key role in the brain's reward system and is involved in mood regulation.
True or False: The amygdala processes emotions.
True. The amygdala is crucial for emotional responses, particularly fear and pleasure.
Fill in the blank: The primary inhibitory neurotransmitter is __________.
GABA (gamma-aminobutyric acid). It helps reduce neuronal excitability throughout the nervous system.
Compare the roles of the hippocampus and amygdala.
Hippocampus: memory formation. Amygdala: emotion regulation.
What structure connects the left and right hemispheres of the brain?
Corpus callosum. It facilitates communication between the two hemispheres.
Cause → Effect: Increased serotonin levels → ?
Enhanced mood and reduced anxiety. Serotonin is associated with feelings of well-being.
What is the function of the prefrontal cortex?
Executive functions such as decision-making, planning, and social behavior.
True or False: Endorphins are involved in pain relief.
True. They act as natural painkillers and are related to feelings of euphoria.
What is the role of the autonomic nervous system?
Regulates involuntary bodily functions: heart rate, digestion, respiratory rate.
Fill in the blank: The neurotransmitter primarily involved in muscle movement is __________.
Acetylcholine. It is essential for communication between nerves and muscles.
What brain structure is critical for regulating homeostasis?
Hypothalamus. It maintains the body's internal balance, including temperature and thirst.
Cause → Effect: Chronic stress → ?
Increased cortisol production leading to various health issues such as anxiety.
What neurotransmitter is often linked to mood disorders like depression?
Serotonin. Low levels of serotonin are associated with mood regulation problems.
True or False: The occipital lobe is responsible for auditory processing.
False. The occipital lobe is primarily responsible for visual processing.
Compare the sympathetic and parasympathetic nervous systems.
Sympathetic: 'fight or flight' response. Parasympathetic: 'rest and digest' functions.
What is the primary function of neurotransmitters?
To transmit signals across synapses between neurons, affecting behavior and mood.
Psychological Theories and Social Influences(16)
Define operant conditioning.
A learning process through which behavior is modified by reinforcement or punishment.
True or False: Socialization only occurs in childhood.
False. Socialization is a lifelong process, influencing behavior and beliefs throughout life.
Compare classical conditioning and operant conditioning.
Classical conditioning: learning through association; Operant conditioning: learning through consequences.
Fill in the blank: The __________ perspective emphasizes how culture shapes behavior.
sociocultural
What is the role of cognitive dissonance?
It motivates individuals to change beliefs or behaviors to reduce discomfort from conflicting ideas.
Cause → Effect: Social influence → __________.
Change in individual behavior
Define the concept of self-efficacy.
Belief in one's ability to succeed in specific situations or accomplish a task.
True or False: Groupthink leads to better decision-making.
False. Groupthink often results in poor decisions due to the desire for consensus.
What is the bystander effect?
The phenomenon where individuals are less likely to help a victim when others are present.
List three agents of socialization.
- Family - School - Media
What does the social learning theory propose?
Behavior is learned through observing and imitating others, especially role models.
Fill in the blank: The __________ theory emphasizes the impact of social roles on behavior.
role theory
Define the concept of cultural relativism.
The practice of assessing a culture by its own standards rather than viewing it through the lens of another culture.
What is the significance of the looking-glass self?
It describes how self-image is shaped by how others perceive us.
True or False: Social norms have no influence on individual behavior.
False. Social norms strongly influence behavior and expectations within a group.
Cause → Effect: Acculturation → __________.
Adoption of cultural traits from another culture.
