Firstly realize that Sapir-Whorf was proven wrong in the strong sense, but is accepted in the weak sense. I don't think there's really any doubt now that learning new symbols and languages, or just enhancing your vocabulary in one language, influences thought. Many mathematicians are especially proud of how accurately proofs communicate, and having gained ...

I've studied this a little bit within the context of timing responses to personality test items. General models of reading speed look at both the time to read the words as well as to comprehend. From memory, eye tracking studies have shown how the eyes will often back track to confusing parts of a sentence (apologies for lack of reference). Some general ...

What explains the tendency of people to not count the letter F's in the word "OF"? One possibility to explain this effect is related to the phenomenon of word skipping. When we read, we do not fixate every word, but skip a certain proportion of words while making educated guesses instead. Whether or not a certain word is skipped seems to depend on its ...

If you really wanted to know you could use models of reading behaviour - e.g. EZ-Reader or Swift. The Rayner reviews are the classic go-to to outlne this kind of thing: Rayner, K. (2009). Eye movements and attention in reading, scene perception, and visual search. The Quarterly Journal of Experimental Psychology (2006) (Vol. 62, pp. 1457-506). It will ...

This paper was written in 2010: Perceptual shift in bilingualism: brain potentials reveal plasticity in pre-attentive colour perception. In this paper, we test whether in Greek speakers exposure to a new cultural environment (UK) with contrasting colour terminology from their native language affects early perceptual processing as indexed by an ...

Sounds like what you're describing is "semantic satiation". Wikipedia explains: The explanation for the phenomenon was that verbal repetition repeatedly aroused a specific neural pattern in the cortex which corresponds to the meaning of the word. Rapid repetition causes both the peripheral sensorimotor activity and the central neural activation to fire ...

Motherese may play a role in emotional development. Soken and Pick write: "Concurrent with the exaggerated speech of motherese, there are probably exaggerated facial displays, allowing infants to explore the particular aspects of the face... Child-centered displays may serve as opportunities for learning about affective events." Walker-Andrews (1997) also ...

A few thoughts spring to mind: Part of the answer might depend on the maximum value of X (if all the messages are relatively short, that's a key piece of information). It doesn't decay, I don't think. The more information presented to the user, the more it all has to put into context with each other. But I don't think it's quadratic, either; that seems ...

The two legs upon which speed reading rests, in short, are chunking and seeking. Chunking is reading multiple words at once, while seeking allows you to find those chunks quickly and efficiently. The first exercise below will solve your subvocalization problems, but I recommend doing both in order to read text more effectively. You'll need: A computer ...

We were looking for an EEG device few years ago. The commercial offers were between 20,000 EUR for a 32 passive electrode to 50,000 EUR for an 64/128 active electrode. This included everything except the computers - some offers were without off-line data processing software. I never considered the EEG systems that were not mentioned in the method section of ...

I believe motherese exists to teach the infant to discriminate phonemes in the native language. Kuhl et al. (2005) show that during the first year language critical period, infants gain an increased ability to discriminate between phonemes of the native language, while their ability to discriminate between phonemes of non-native languages declines. ...

Fonagy and Target, although they do not specifically cite the term 'Motherese', believe that what they call 'Marking'- signalling an unreality or playfulness in mirrored displays of affect can play a crucial role in the development of a faculty they call 'Mentalization'. According to their model, newborns experience affect as all-pervading, and do not see ...

I just had a project where I had to figure this out. I found that a good rule of thumb was the following: $$timeToRead = 1300 + (chars * 65);$$ So that's an initial time of 1300ms to adjust to what you need to be reading and about 65ms per character including spaces.

Here is a lexical decision task I wrote years ago using PHP and Javascript (github link). Distributed as-is, no documentation. There is still some vestigial code in there for an experimental manipulation.

One option is to use Inquisit Web Edition. Here is an example script with a lexical decision task. Unfortunately, it is not free and it requires installation of a plug-in. Version 4 of Inquisit runs on OSX and Windows. Thus, it wont work in Linux or on phones, tablets, etc.

Some cognitive scientists I heard are clear about benefits of being bilingual as exposed by @Damien or here - http://www.nytimes.com/2011/05/31/science/31conversation.html?_r=0. They also do not hide the associated cognitive costs especially at a young age. I found the following presentation very interesting ...

It seems to me that it'd be a type of a tip-of-the-tongue phenomenon caused by bilingualism. If you don't use German regularly, it might be attributed to language attrition, but this seems unlikely if you're still being exposed to German more than English. http://en.wikipedia.org/wiki/Tip-of-the-tongue_phenomenon#Effects_of_bilingualism

Difficulties with language is not actually a symptom of autism. Autism Spectrum Disorder involves difficulties in social communication and interaction, as well as restricted and repetitive interests or behaviours (DSM-V, 2013). The term "social communication" is referring to difficulties in the social aspects of language and other communication, such as ...

This is a very interesting question. Unfortunately, I was not able to find something that would give you a clear answer. In essence, I think this question is asking for a cognitive mechanism underlying word generation in phonemic/phonological verbal fluency test which is a matter that has rarely been addressed (Robinson et al, 2012). Studies such as the ...

Just for reference, I ended up writing simple web-based lexical decision task software myself.

It sounds like you're talking about Latent Semantic Analysis. Here's their rundown of what it is. However, LSA as currently practiced has some additional limitations. It makes no use of word order, thus of syntactic relations or logic, or of morphology. Remarkably, it manages to extract correct reflections of passage and word meanings quite well without ...
