Hey G+ I haven't been active for a while, and I won't be until after October 8, which election day in Nova Scotia.

I am running as a candidate in the election, you can follow my political musings and campaign on Facebook www.facebook.com/delorey4antigonish and Twitter @Delorey4Nish and my website www.delorey4antigonish.ca

So did you hear the news?

I am the Liberal Candidate for Antigonish, Nova Scotia in the next provincial election, which is expected to be called very soon.

What say you G+, on a citizen`s responsibility to seek public office when asked to put their name on a ballot?  If we have a responsibility to vote in an election, does that responsibility extend to those with the ability to serve in pubic office, that they ought to pursue office?

Hey +Marc Robichaud what time is it?

Oh yeah, that's right, it's +Pebble Time!

My +Pebble is in Halifax ... if the stars align I could get it tomorrow; if not next week for sure!

WOOT!

Now this is awesome!

We've seen Hangouts for music, photos, and news media, but now hangouts for academics ... very cool!

If you've never been to an academic conference, this poster session will give you a taste of what to expect ...
Posterside Hangouts is a new Hangouts On Air, which is hosted by the Science on Google+ Community (http://goo.gl/uhJCN). The main goal of this HOA series is to recreate a poster session-like atmosphere here on G+, so researchers can present their recent findings. Presentations will be grouped by discipline and individual presentations will last approximately 10 – 15 minutes.

Do you have a recent conference presentation, manuscript, or book that you would like to share with the Google+ community? Do you want to give your undergraduate or graduate students practice presenting their research? If yes, then let us know by filling out this short form: http://goo.gl/e0KPhE.

When audition dominates vision: Evidence from cross-modal statistical learning
Presenting information to multiple sensory modalities sometimes facilitates and sometimes interferes with processing of this information. Research examining interference effects shows that auditory input often interferes with processing of visual input in young children (i.e., auditory dominance effect), whereas visual input often interferes with auditory processing in adults (i.e., visual dominance effect). The current study used a cross-modal statistical learning task to examine modality dominance in adults. Participants ably learned auditory and visual statistics when auditory and visual sequences were presented unimodally and when auditory and visual sequences were correlated during training. However, increasing task demands resulted in an important asymmetry: Increased task demands attenuated visual statistical learning, while having no effect on auditory statistical learning. These findings are consistent with auditory dominance effects reported in young children and have important implications for our understanding of how sensory modalities interact while learning the structure of cross-modal information.

Automatic selection of eye tracking variables in visual categorization for adults and infants
We present a computational approach for the selection of diagnostic eye tracking variables. Previous methods for the selection of eye tracking variables have been ad-hoc or hypothesis driven. In the absence of a good hypothesis, researchers are left to experiment with many alternatives. To resolve this problem, we use feature extraction and classification algorithms from machine learning to automatically identify the eye tracking variables that best correlate within sample eye tracking sequences belonging to the same category yet discriminate between categories. This approach allows us to extract the few (i.e., two to four) most diagnostic features from a pool of dozens. While previous work required the testing of a large number of hypotheses, we demonstrate how the proposed  methodology yields the same result without the need to test a large number of alternative hypotheses. Instead, our method is data driven, i.e., the resulting model is obtained from the data. The proposed methodology was verified in a visual categorization task with adults and infants. Here, we presented infants and adults with a category learning task and tracked their eye movements. We extracted an over-complete set of eye tracking variables encompassing durations, probabilities, latencies, and the order of fixations and saccadic eye movements. The method defined identified a small set of variables that allows us to predict category learning among adults and 6- to 8-month-old infants and suggests that the looking strategies of adults and infants are distinct.

Foreign accent does not influence cognitive judgments
A recent paper by Lev-Ari and Keysar (2010) reported that the processing fluency associated with non-native speech causes non-native speakers to sound less credible. The authors found that the same trivia statements were rated as less truthful when spoken by a non-native speaker of English. The present paper reports the results of three studies that attempted to replicate the findings of Lev-Ari and Keysar (2010) by focusing on processing fluency manipulations other than accent. Although we used virtually the same methodology as Lev-Ari and Keysar (2010), we failed to replicate the key finding that foreign-accented speech is less credible than native-accented speech. The implications of this finding is discussed.

Positive Mood May Enhance Cognitive Flexibility: Evidence from category learning
Theories of mood and its effects on cognition suggest that positive mood may increase cognitive flexibility. This increased flexibility is associated with areas in the prefrontal cortex and the anterior cingulate cortex, both of which play crucial roles in hypothesis testing and rule selection. As such, cognitive tasks that rely on these behaviors may benefit from positive mood, whereas tasks that do not rely on these behaviors should not benefit from cognitive flexibility and/or positive mood. We explored this idea within a category-learning framework. positive, neutral, and negative moods were induced in our subjects and they learned either a rule-described or a non-rule-described category set. Subjects in the positive mood condition performed significantly better than subjects in the neutral or negative mood conditions when learning the rule-described categories. Mood had a less obvious effect effect on the learning of non-rule-described categories, but computational modelling suggested that subjects who learned in a positive mood were more likely to use the optimal learning strategy. These results have implication for theories of category learning, and also have implication for the understanding the effects of local, environmental factors like mood on performance.

This looks promising ... where's Google TV (to go with Movies) in Canada?  I thought our recent updates to copyright legislation were supposed to address the media concerns releasing content in Canada ... apparently not.
Rdio launched their new video (TV and Movie) service today. It's basically a movie and TV rental app with support for countries that aren't the US (Nice one, #Vdio!)

No idea how it's going to work on Google TV though -- has anyone tried it?

It is a concern... We have some great privacy commissioners in Canada, but little political will, or so it seems.

Is Bradley Manning a traitor or a hero?
Am I Bradley Manning?
What would it take to be Bradley Manning?
Could YOU be Bradley Manning?
Something to think about

Will Google Textbooks be the end of CourseSmart???

Will have to see some Canadian Content.
Would have liked to see that Google Textbooks also incorporated OpenTextbook options ...
