1. 0:00Do you have students who read with great difficulty, who have a bad handwriting, or have a little more difficulty
2. 0:05understanding a text or solving a mathematical operation?
3. 0:09Did you know that it may be due to some fault in thier laterality?
4. 0:13I'm Natalia Cardenas and today we're going to talk about what laterality is and how to find
5. 0:18some problems in it.
6. 0:25The laterality is the natural preference that our body has to define which side
7. 0:31right or left, will direct our actions.
8. 0:34It is defined by 4 domains:
9. 0:36• Ear, •eye,
10. 0:38• hand and •foot.
11. 0:39The laterality allows the right cerebral hemisphere communicate without any contretemps
12. 0:45with the left lateral hemisphere.
13. 0:48Therefore, a defined laterality will allow our brain to develop all
14. 0:54its cognitive potential.
15. 0:57The laterality is much more noticeable in the hands, which commonly defines us
16. 1:03as right-handed or left-handed.
17. 1:04But speaking strictly of laterality what defines us as right-handed or left-handed is
18. 1:09the preference to use the 4 domains on our right side or on our left side.
19. 1:15That is, if you are right-handed, you should prefer to use your right eye, right ear, right hand
20. 1:23and right foot.
21. 1:24And if you are left-handed you should prefer to use your left eye, left ear, left hand
22. 1:31and left foot.
23. 1:32That means that you have a homogeneous laterality.
24. 1:37When only one of the domains eye, ear or foot domains is contrary to the rest,
25. 1:42the result is crossed laterality.
26. 1:44For example, if you have preference for your right eye, your right hand and your right foot
27. 1:50but your left ear, it means that you have crossed laterality.
28. 1:55It is said that you have a cross in the left ear. Another example would be that you have preference
29. 2:02to use your left eye, your left hand, your left foot and your right ear. You also
30. 2:09have crossed laterality but right ear.
31. 2:14Contrary laterality occurs when you are forced to use a domain that you naturally
32. 2:20do not use, the classic example being the right hand and the left hand when they forced
33. 2:26left-handed people to write with their right hand.
34. 2:31Writing with both hands does not define you as ambidextrous, an ambidextrous has the facility
35. 2:36to do all the actions with the right hand and with the left hand.
36. 2:40For example, brushing teeth, covering or uncovering a bottle or throwing a ball.
37. 2:45Therefore, if we look only at writing, it is very easy to confuse ambidextry
38. 2:51with crossed laterality.
39. 2:52Before we will talk about the problems that can arise from not having a defined laterality,
40. 2:58I would like to comment that there are children who define it as laterality at 4 or 5 years or even
41. 3:03before and start reading at 3 years, it is very likely that these children have high
42. 3:08capabilities.
43. 3:09But normally a child can define his laterality until he is 7 years old.
44. 3:14And in some countries we ask to start reading and writing at 6 years of age where children are still
45. 3:19discovering which side of their body is going to direct their actions.
46. 3:24This causes problems of reading, writing and comprehension, we are forcing the little kids
47. 3:30to start reading and writing when we must continue stimulating their senses and their motor skills.
48. 3:37Science has observed that the development of the thoughts or actions of people
49. 3:42with crossed, contradictory or ambidextrous laterality are slow and can be easily
50. 3:49blocked and this is reflected in their lack of concentration, in their slowness to understand some texts,
51. 3:56in their handwriting and its poor reading and in its difficulty in solving
52. 4:01mathematical logical problems or just understanding them.
53. 4:04And the worst of all is that it can continue even when we are adults.
54. 4:08To know the laterality of your students make the following steps:
55. 4:13Look with what hand they draw, with what hand they throw an object, with what hand they uncover a
56. 4:19bottle of screw cap, with which hand they take snacks like peanuts or potato chips.
57. 4:24To know their preference foot:
58. 4:26Look at what they start to walk or run,
59. 4:32what foot do they support when you ask them to maintain balance
60. 4:35and with what foot they kick a ball.
61. 4:38To know their eye preference:
62. 4:40Ask them to cover one of them and read a word from the board, peek through a
63. 4:45slit or look through a telescope
64. 4:48And finally to know their preference by ear:
65. 4:52observe which ear their prefer to use when speaking on the phone,
66. 4:56ask them to listen through the window or the classroom door.
67. 4:59Remember that laterality is defined by the side that they use most frequently when performing
68. 5:05these actions.
69. 5:06Before saying goodbye, I would like to remind you that it is very common for students with contradictory
70. 5:12, crossed or ambidextrous laterality have behavioral problems, get bad grades
71. 5:17or you notice that they are a little slower than the rest of their classmates.
72. 5:21So before qualifying them as disastrous or bad students make sure their laterality
73. 5:28is defined.
74. 5:29Today I have a challenge for you. Observe yourself, get a test of laterality, share in our
75. 5:34Instagram account a photo or a video while you are doing the test.
76. 5:38And in our Twitter account with #MyLateralityIs your results.
77. 5:43If you liked the video, give it a like and share it.
78. 5:45And subscribe to our channel for more neuroeducation videos.
79. 5:49It´s define by 4 domains, ear, (laughs) feet and hands.
80. 5:56And to define us like left-handed we should use our left eye, left ear, left hand
81. 6:04and right foot. (laugh)
82. 6:12I was doing so well.
