John Garcia was an American psychologist very well-known for his researches that focused on taste aversion in rats and for discovering conditioning taste aversion. Taste aversion is often developed after having a drink or food that causes nausea, vomiting or sickness afterwards. Garcia challenged the idea that:
- any association can be learned equally well.
- conditioning takes place in an even faster and stronger manner when the conditioned stimulus is ecologically relevant.
Therefore, the ability to develop a taste aversion works as a survival mechanism. And, regardless of the taste of the food, sights and sounds, ones can tricky themselves into not liking the taste simply because they relate sickness with it.
Identical twins are two people born at the same time from the same person that look alike. The difference is they may develop is in personality from different experiences but usually they have different birthmarks
Answer: A unitary system is one in which power can be granted to or taken back from regions by a decision of central authority without the involvement of the regions themselves while a federal system is one in which there is division of power between a federal government and sub-federal governments(most times state and local governments)
Explanation: characteristics of unitary system include:
1. central government has sovereignty over what happens at every sub-level
2. sub level competencies are defined by statute and not enshrined in the written constitution
3. There is no direct participation of sub-levels in constitutional amendments
Characteristics of federal system include:
1. federal laws supercede state laws
2. federal laws must be applied by state courts
3.federal powers are limited and state powers are protected by the constitution
4. There's representation of states in parliament and states actively participate in constitutional amendments
Example of governments practising unitary system is the United Kingdom, Norway, Romania and Israel while federal system is practised in the United States, Canada, Germany and Australia.
