Why is the birth canal so small?

The smaller birth canal became a limiting factor to brain size increases in early humans and prompted a shorter gestation period leading to the relative immaturity of human offspring, who are unable to walk much before 12 months and have greater neoteny, compared to other primates, who are mobile at a much earlier age.

Human consciousness emerges on the interface between three components of animal behavior: communication, play, and the use of tools. These three components interact on the basis of anticipatory behavioral control, which is common for all complex forms of animal life.

What is the role of the brain in controlling behavior?

Of course, the brain plays a critical role in the control of behavior. Complex forms of behavior (including consciousness) necessarily require, and become possible due to, the complexity of the controlling brain. But there is no isomorphism between a controlling system and a controlled system.

Is consciousness a game?

Hence, consciousness is not a game, as previous socio-linguistic theories regarded it, but rather a free play (Derrida, 1975) whose rules may appear and disappear like clouds in a windy day. From the early socio-linguistic point of view, consciousness is its own manifestation in systems of signs.

How does operant conditioning affect human behavior?

Quite simply, operant conditioning controls human behavior via positive and negative reinforcement. A person who finds themselves constantly in trouble with the law when they break certain rules typically learns to associate rule-breaking with legal issues. Likewise, an individual who regularly studies for exams and aces them comes to associate studying with positive grades. When it comes to human behavior, people tend to steer clear of what causes them pain and gravitate towards pleasure and personal satisfaction. These are some of how conditioning, both classical and operant, is theorized to impact human behavior.
