Question

QUESTION 25 Natural selection is a rapid process that changes features of an organism in just one generation a superior method of adaptation relative to learning because it benefits all members of the species. based on a fitness criterion: that is, the fastest, largest, strongest, most distinctly marked members of the specics are most likely to survive O a process that enables the genetic transmission of both physical features and behaviors. QUESTION 26 The Rescorla-Wagner model predicts the blocking phenomenon because on the compound conditioning trials.

Explanation / Answer

25.Natural selection is based on fitness criterion,fastest strongest and most distinctly member of species are more likely to survive.The process in nature by which, according to Darwin's theory of evolution, only the organisms best adapted to their environment tend to survive and transmit their genetic characters in increasing numbers to succeeding generations while those less adapted tend to be eliminated. 24.Extinction is a learning process, event or behavior that was previously predictive of a particular outcome is no longer predictive.Extinction refers to the gradual weakening of a conditioned response that results in the behavior decreasing or disappearing. In other words, the conditioned behavior eventually stops. For example, imagine that you taught your dog to shake hands. Over time, the trick became less interesting. 30.The answer is "a shock".Conditional emotional responses (CERs ) are learned emotional reactions like anxiety or happiness that occur as a response to predictive cues. Most American psychologists use the -ed form of the word, calling CERs "conditioned emotional responses." However, to be consistent with earlier arguments about the translation of Pavlov's terms from Russian to English, we will stay with the term conditional except when quoting people who use the -ed form. The process of acquiring a CER is similar to the process of acquiring any other conditional response. A signal comes before a biologically significant event, and the organism learns the correlation (literally "making the connection" on a neural level). For example, we could sound a tone and give you an electric shock. Such fear conditioning establishes a CER quickly. After one or two pairings, the sound of the tone will send a wave of apprehension through amygdalar circuits of any organism capable of processing fear. Due to time limit only some could be answered,the remaining can be asked as another question,they will be answered,thankyou for your cooperation.
