    Neuronal group selection combines maturation theory and dynamic systems

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Neuronal group selection is a theoretical framework that combines maturation theory and dynamic systems. Maturation theory suggests that the development of the brain and its neural networks occurs in a predetermined sequence, while dynamic systems theory emphasizes the importance of interactions between different elements in the system. Neuronal group selection proposes that the brain's development is shaped by both genetic factors and environmental influences, and that the selection and refinement of neural connections occur through a dynamic process. Therefore, the statement "Neuronal group selection combines maturation theory and dynamic systems" is true.

    Rate this question:

  • 20. 

    Primitive reflexes are surpressed around 3 - 4 months after birth

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Around 3-4 months after birth, primitive reflexes are typically suppressed. These reflexes, such as the Moro reflex or the grasp reflex, are automatic responses that newborns exhibit in response to certain stimuli. As the baby's nervous system develops and matures, these reflexes gradually disappear and are replaced by more voluntary and controlled movements. This suppression of primitive reflexes is an important milestone in a baby's motor development and indicates the progress of their neurological development.

  • 24. 

    Form of memory that involves remembering a stimulus that is not present.

    • Recall

    • Recognition

    • Selective memory

    • Deviant memory

    Correct Answer
    A. Recall
    Explanation
    Recall is the correct answer because it refers to the form of memory that involves remembering a stimulus that is not present. It is the ability to retrieve information or experiences from the past without any external cues or prompts. This can be done by consciously bringing back previously learned information or by reconstructing past events based on memory. Recall is different from recognition, which involves identifying or remembering a stimulus when it is presented again. Selective memory and deviant memory are not accurate terms for this form of memory.

    Rate this question:

  • 25. 

    Memory span can only have 7±2 items

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement that memory span can only have 7±2 items is true. This is based on research in cognitive psychology that suggests that the average person's short-term memory can hold around 7 items, give or take 2. This concept is known as Miller's Law and has been supported by various studies. It means that individuals can typically remember around 5 to 9 pieces of information at a time before their memory starts to deteriorate.

    Rate this question:

  • 28. 

    The renewed response to a new stimulus is known as dishabitation

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Dishabituation refers to the recovery of a response to a previously habituated stimulus when a new stimulus is presented. It is a process in which the individual's response to a habituated stimulus is renewed or revived due to the introduction of a novel stimulus. In other words, dishabituation occurs when a person becomes responsive to a previously habituated stimulus again because of the introduction of a new stimulus. Therefore, the statement "The renewed response to a new stimulus is known as dishabituation" is true.

    Rate this question:

  • 29. 

    Which type memory is more advanced.

    • Recognition

    • Recall

    Correct Answer
