A

other symptoms of parietal lobes damage

18
Q

• Inability to locate and recognize parts of the body or self

A

other symptoms of parietal lobes damage

19
Q

• Neglect of visual, auditory and somatosensory stimuli on the side of the body opposite to the lesion

A

Contralateral Neglect

20
Q

defective sensation and perception and

defective attention

A

cause Contralateral Neglect

21

Wernicke’s Aphasia

31
Q

• Comprehension of speech is impaired

A

• Comprehension of speech is impaired

Wernicke’s Aphasia

32
Q

Speech is: –

fluent but meaningless (word salad) –

devoid of any content –

neologisms

A

Wernicke’s Aphasia

33
Q

Content ranges from mildly inappropriate to complete nonsense

A

Wernicke’s Aphasia

34
Q

The ability to encode, store, retain, recall and recognize information

A

Memory

35
Q

Memory

A

duration of memories and formation and retrieval of information

36
Q

Four types of memory based on

A

duration of retention

37
Q

Sensory memory •

A

200-500 ms after input is perceived

38
Q

– Working memory •

A

Focuses on the processing of briefly stored information

39
Q

– Short-term memory •

A

Holds a few items briefly before the information is stored or forgotten

40
Q

Long-term memory •

A

Relatively permanent and limitless storehouse

41
Q

Three stages in the formation and retrieval of memory:

A

Encoding storage retrieval

42
Q

• Processing and combining received information

A

encoding

43
Q

• Creation of a permanent record of the encoded information

A

storage

44

Recognition

A

Recall
