Responsive and Behaving Brain Questions

 

 

Psychology 1: Video 3: The Responsive Brain (In: videorespbrain.ws) 1. Key terms: Reciprocal, Feed-forward, Feed-back, Behavior, Modify, physical and psychological stress, learning, maze, Enrichment and deprivation, Plasticity, Perception. From the behaving brain video: please remember learn, scopalomine, physiostingmine, acetylocholine, dendrite, soma, axon, transmitter, and the descriptions of how brain Anatomical structures contain INHERENT behaviors). Those structures common to both videos include brain stem, hippocampus, amygdale and cortex.

Novel terms and definitions

Please take notes in margin where needed: 2. Overview:

a. Brain executes behavior (feed-forwara) that modifies brain structure and

the effort and efficiency to execute future behaviors (feed-back). b. Internal modification of behavior: relationship to memory and the concept of Apriori origin of behavior.

C. The relationship between the Storage of the consequences of actions on the execution of future acts and development of behavior and mental processes.

The role that the Concept of error correction has on energy expended during performance of behavior.

e. Selective advantage that these items might provide.

The relationship these items have with natural selection and ability to survive and reproduce.

g. Please attend to the micro-macro, physical-psychological organization of the examples in the video.

3. Examples illustrating the above topics. Please note that the types of observation included naturalistic and laboratory setting, and initial state and manipulated states were described.

a. Field (Miami U): Premature babies in Intensive Care Unit. Hypothesis: Physical Touch stimulation adjusts neural growth and future cognitive development. Independent variable: infants that do and do not receive massage: Dependent variable: brain weight, alertness, cognitive abilfty. Finding: Massage increased brain activity to 8 months after end of experiment.

b. Shandberg: Rats. Hypothesis: If Mother’s physical touch adjusts neural growth and future cognitive development then. Independent variable: rats that do receive mothers touch and rats that receive artificial physical touch when deprived of mother; Dependent variable: brain weight, alertness, cognitive ability. Finding: Mothers touch increased brain activity beyond duration of experiment.
