Well... it was obvious that the reward system is involved. It is in virtually every addiction... but working memory... hmmm that's really interesting...
Nicotine Withdrawal Affects the Brain's Cognitive System

Most attempts to stop smoking are unsuccessful in the long term, even with smoking cessation methods such as nicotine replacement therapy. Penn State researchers are looking at how reward processing and working memory may determine why smokers choose to smoke again after trying to quit.

+Hank Johnson​​ set us up for a challenge and the Chilean Resistance answered accordingly!
We planned and moved all over the country to achieve a positive difference in the MU account across our country cells.
Many agent all over the country moved even when for us it was the middle of the working day. We had funny stories of people lying at their offices to get an early leave or a free day (That we won't disclose here, just in case 😉). Some even went to places with usually no MU to maximize the delta results.

These are the results. Negative differences are shown in red and positive ones are shown in green.

We might have lost the global account. But in Chile, we feel we won and we had a wonderful time playing this challenge!!

Why Do We See Similarities Across Languages? The Brain May Be Responsible

For years, researchers have been interested in the similarities seen across human languages. A new study led by University of Arizona researcher Masha Fedzechkina suggests that some of those similarities may be based on the human brain's preference for efficient information processing.

The research is in Psychological Science. (full access paywall)

Have you ever feel like the only thing you want to do is cry but you smile instead?

Jerry Fodor passed away... I feel there is a hole in my modular mind now... 😭😭😭😭

Your papers, conferences, and ideas will be greatly missed!! (Even if I didn't agree with some points and all that) 😭😭😭😭😭

"Over the years, I have become convinced that xsl [cross-situational learning] is the basic learning mechanism that humans use to learn word-meaning mappings. xsl learning allows the learner to infer the meaning of a word by using the covariation of meanings that occur in the contexts of different situations. In Smith et al. (2006), we have shown that xsl can be highly robust under large amounts of referential uncertainty (i.e. a lexicon can be learned well even when an agent hears a word in contexts containing many possible meanings). However, this was shown using a mathematical model containing many unrealistic assumptions. When relaxing such assumptions, such as using a robot (cf. this book), having many agents in the population (Vogt & Coumans 2003) or assuming that words and meanings occur following a Zipfian distribution (Vogt 2012), xsl is no longer that powerful.
To resolve this, a learner requires additional cues to learn a human-size lexicon, such as joint attention or corrective feedback."

"We found that intelligence was not associated with global modularity features (e.g., number or size of modules) or the whole-brain proportions of different node types (e.g., connector hubs or provincial hubs). In contrast, we observed characteristic associations between intelligence and node-specific measures of within- and between-module connectivity, particularly in frontal and parietal brain regions that have previously been linked to intelligence. We propose that the connectivity profile of these regions may shape intelligence-relevant aspects of information processing."

Nodding Raises Likability and Approachability

Full article at http://neurosciencenews.com/nodding-likability-8042/

The act of nodding positively affects the subjective likability of people by about 30 percent and their approachability by 40 percent, according to a study conducted by researchers from Hokkaido University and Yamagata University in Japan.
