Biological Approach to Behavior Flashcard 2

Front

Which of the following is not true of Rosenzweig, Bennett & Diamond's (1972) study?
Options:
It is difficult to generalize the findings to humans.
The experiment was able to control for extraneous (confounding) variables.
There are ethical concerns regarding the treatment of the animals in the study.
There was evidence of neuroplasticity in the rats - the frontal lobes were denser as a result of dendritic branching in the enriched environmental condition.

Back

The experiment was able to control for extraneous (confounding) variables.

Front

According to Carrion (2009), what effect can stress in the environment have on the brain of children?

Back

Cognitive impairment caused by a smaller hippocampus.

Front

What research method did Maguire use for her study of brain plasticity in taxi drivers?

Back

A quasi-experiment using a single-blind control.

Front

The formation of new dendritic spines is unaffected by altering a test animal's visual or tactile environment.

Back

False

Front

Neuroplasticity refers to

Back

the ability of the brain to change so that a given function can be transferred to a different location in the brain

Front

Which of the following best describes cortical remapping? Options: The process by which the brain strengthens connections between existing neurons, The reorganization of cortical areas in response to learning, experience, or injury, The development of new neurons in the brain throughout a person's life, The phenomenon of lateralization of brain function, where different hemispheres handle specific tasks

Back

The reorganization of cortical areas in response to learning, experience, or injury

Front

Which of the following best illustrates the concept of sense substitution? A person using a hearing aid to amplify sound for better auditory perception. A blind individual using tactile cues to read Braille, thereby substituting touch for vision. A musician developing perfect pitch through extensive training. An individual experiencing synesthesia, where sounds trigger visual sensations.

Back

A blind individual using tactile cues to read Braille, thereby substituting touch for vision.

Front

What is the primary role of long-term potentiation (LTP) in the brain?

Back

To enhance the strength of synaptic connections following repeated stimulation

Front

Which of the following statements about synaptic pruning is true? Synaptic pruning occurs exclusively in childhood and does not happen in adulthood., It is a process that increases the overall number of synapses in the brain., Synaptic pruning helps to refine neural circuits and improve the efficiency of brain function., It only affects sensory neurons and has no impact on cognitive functions.

Back

Synaptic pruning helps to refine neural circuits and improve the efficiency of brain function.

Front

Which of the following factors can promote neural arborization during brain development?
Options:
Increased stress levels in early childhood,
Environmental enrichment and learning experiences,
Genetic predisposition alone, without environmental influence,
Prolonged periods of inactivity and lack of stimulation

Back

Environmental enrichment and learning experiences
