Bounty: 250

In the visual sciences it is known that the oblique effect can be reduced by means of training. The oblique effect is observed when testing subjects psychophysically with a grating acuity task (e.g., the BaGa test). Visual acuity is better when horizontal or vertical gratings are tested than when diagonals are used. The performance in discerning diagonal gratings has been shown to improve after training subjects, although performance in the cardinal directions stays better than the oblique stimuli.

The oblique effect has been observed in the tactile sense too. However, the amount of papers in the scientific literature is quite restricted in the tactile modality. I wasn’t able to find evidence in the literature whether training can improve people’s performance in tactile diagonal grating tasks.

Does training improve people’s performance in oblique tactile gratings relative to gratings with horizontal/vertical orientations?

In an interview with a Czech neurologist Syka, I’ve heard that much of the mental health (such as the ability to reason, communicate and process information) in older age mainly depends​ on the amount of informational ballast we create. The argument states that with this additional information, we unnecessarily wear some of the basic mental mechanisms out (Even though there’s no the effect of “too much memories”). Does knowledge of more languages tend to improve or worsen these mental skills?

Sort a list of tuples by Nth item in Python

Suppose you have a list of tuples that looks something like this:

[('abc', 121),('abc', 231),('abc', 148), ('abc',221)]

And you want to sort this list in ascending order by the integer value inside the tuples.

We can achieve this using the key keyword with sorted().

sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=lambda x: x[1])

key should be a function that identifies how to retrieve the comparable element from your data structure. For example, the second element of the tuple, so we access [1].
