Keywords

💡Mental Rotation

Mental rotation refers to the cognitive ability to manipulate and rotate objects in the mind’s eye. In the video, it is highlighted as a crucial skill utilized when solving jigsaw puzzles, as individuals must envision how pieces might fit together from different angles.

💡Working Memory

Working memory is the system responsible for temporarily holding and processing information needed for cognitive tasks. The video mentions working memory as essential for remembering where puzzle pieces are placed and how they relate to the overall image.

💡Episodic Memory

Episodic memory is the ability to recall specific events or experiences from one’s past. In the context of jigsaw puzzles, the video suggests that episodic memory helps individuals remember where certain pieces are located and how they have previously been used.

💡Processing Speed

Processing speed is the rate at which an individual can perceive, interpret, and respond to information. The video associates this with the rapid mental tasks required when determining where a puzzle piece should go.

💡Task Switching

Task switching is the ability to shift focus between different tasks or cognitive processes. The video implies that while solving puzzles, individuals often switch between different types of cognitive tasks, such as analyzing shapes, colors, and patterns.

💡Mindfulness

Mindfulness is a mental state achieved by focusing on the present moment while calmly acknowledging and accepting one's feelings and thoughts. The video draws a parallel between jigsaw puzzles and mindfulness practices, suggesting that the focused nature of puzzling can lead to relaxation and stress reduction.

💡Ventral Pathway

The ventral pathway, also known as the 'what' pathway, processes information related to object recognition and form representation. In the video, this pathway is mentioned as responsible for processing the visual information of what is on a puzzle piece.

💡Dorsal Pathway

The dorsal pathway, also known as the 'where' pathway, processes spatial information, such as the location of objects. The video explains that this pathway helps in remembering where puzzle pieces are placed and integrates spatial information with object recognition.

💡Integration

Integration in this context refers to the brain's ability to combine different types of information, such as visual and spatial data, to perform complex tasks. The video highlights the challenge of integrating 'what' and 'where' information to accurately place puzzle pieces.

💡Leisure Activities

Leisure activities are non-obligatory activities that individuals engage in during their free time for enjoyment and relaxation. The video emphasizes the cognitive benefits of engaging in a variety of leisure activities, including jigsaw puzzles, reading, dancing, and playing card games.

you don't realize that you are doing

this but it's important to solve jigsaw

puzzles it's such a focused task that M

can relax also M your mind something

like it's similar like meditation like

mindfulness training in general people

say they've they feel really relaxed and

after jigsaw puzzling and this

relaxation is really important for

psychological health

[Music]

for example you have this piece jigsaw

puzzle on and you look at it so the

first thing which is happening the

information gets into your eyes goes

through to the occipital cortex from

there and there are two pathways so

there's one pathway going like in this

direction we call it ventral that's a

lower part and there's this pathway the

dorsal pathway and they they are

processing different information for

example the the ventral path in this

direction is processing the image on the

jigsaw puzzle in the what information

what is on on the puzzle piece and then

you put this puzzle piece maybe here in

the left upper corner of this and so

remember where you put it and where you

saw it and so that's where information

it's going the dorsal way and those

informations what and where somehow the

brain needs to integrate this

information to make use of it again and

this is like a really difficult task for

the brain to integrate again all this

information and so you also need this

integration to find the right pieces

again

[Music]

there have many leisure activities which

with which you can like target brain

functions and in general we find that

it's important to do many different

leisure activities and not just doing

one again and again so if you think

about training the brain it's most

important to have like this variations

in in tasks and then cheek so passing is

just one task next to other tasks I

think it might be probably better than

watching television because watching

television is very inactive but for

example reading and dancing and doing

card games it's the accumulation of all

these activities and just jigsaw puzzles

one piece and the whole puzzle
