BLOA Environment and physiology

5 important questions on BLOA Environment and physiology

Neuroplasticity (brain plasticity)

The ability of the brain to adapt to the environment.

It allows the brain to change its structure and function, in response to the external environment.

Generate Adaptation Syndrome (3 stages)

Stage 1: Alarm (fight or flight)
Stage 2: Resistance (body adapts)
Stage 3: Exhaustion (body is not able to resist the stressor anymore)

SRRS -  Holmes-Rahe Social Readjustment Rating Scale

Measures a stress as an inventory of life changes, by assigning various life changes a mean value which is meant to indicate how stressful the life change is.
The more significant the life change, the higher the stress rating.

How is Curtiss's (1977) case study of "Genie" an example of  environmental effects on physiology?

"Genie" was isolated from human company and from any kind of stimulation, therefore her brain development and her physical development were damaged.

Which of the following statements about the effect of the environment on physiology is not true?


The environment has little or no effect on the adult brain.


Explanation:
For a long time, it was assumed that as we become older, the connections in the brain became fixed, and then it was just a matter of time before we started “losing” brain cells. However, this assumption is being aggressively challenged by recent studies showing that the brain never stops changing.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
