Question 1

one pro and one con of using schema

Answer 1

pro: helps us to predict what will happen in our environment based on past experiences and prevents us being overwhelmed with stimuli
con: sometimes schema is not useful if it leads to perceptual errors or inaccurate memories

Question 2

why can information only travel in one direction at a synapse

Answer 2

neurotransmitters travel across the synapse by diffusion from high to low conc so must travel from pre to post synaptic membrane. Also the receptors for the neurotransmitters are only present on the post synaptic membrane
