#SFUPsychology students! We are looking for people to participate in our EEG studies. Each session takes two hours or less. We pay you $20 as a small token of our appreciation for helping us in our scientific pursuits!

Target-elicited N2pc and singleton detection positivity (SDP) predict working-memory capacity when participants decide to search or not on a trial-by-trial basis.

#Attention is theorized to play a key role in #WorkingMemory, a link between selective-enhancement processes & WM has proved elusive. @_DanielTay & @JmcdInHEL reveal this missing link and the condition that is sufficient to reveal it #PLOSBiology https://t.co/0C9JbuzBXS

The deadline to apply for the SFU PhD Program in Psychology is quickly approaching (Dec 1, 11:59 PM PST)! If you're interested in studying attention and distraction using EEG and behavioural measures, please do not hesitate to contact me! https://t.co/YuSHZ2CzDD

5) Many groups are working to increase voter participation among students, like https://t.co/CLLyz0quG5 You can also work with them on your campus and direct your students to do the same. 6) Write a letter in your faculty newsletter with any of the ideas here.

Dear fellow profs, especially those of you in swing states: According to the Higher Education Act of 1965, it is not only our right, but our obligation to teach civic engagement. We have at least some influence over our students, so let’s use it! Here are some ideas....

Something new from my lab! The attentional blink affects the ability to suppress salient visual distractors. Please share if you think it is cool. @ResearchGate:

People have difficulty responding to a second target (T2) while they are busy processing a preceding target (T1). But can people suppress a salient visual distractor (D2) that accompanies T2? Is there an attentional blink for distractor suppression?

Congrats to Andrew Lowery for publishing this cool paper! It is available on JEPGEN (online first) and on my ResearchGate page. Revisiting the automaticity of reading: Electrophysiological recordings show that stroop words capture spatial attention.

Interference in the Stroop task is reduced when the word and color patch are placed at different locations and is diluted further by the presence of another distractor that is response neutral. Such...

What’s wrong with this picture? 1—Iowa's 88-year-old, ANTI-ABORTION Senator Chuck Grassley is running for re-election. 2—His opponent called the recent SCOTUS decision "a direct attack on women." 3—@APA’s affiliated "Psychology PAC" just donated $2500 to Grassley’s campaign.

Do salient visual objects invariably capture attention? Authors Daniel Tay, @ali_jannati, Jessica Green & @JmcdInHEL investigated by recording brain electricity in a novel paradigm. Findings detailed in @APA_Journals Human Perception & Performance. Link: https://t.co/nRoV379DCz

Our recent study on visual orienting activity just appeared as an Early Release on the Journal of Neuroscience website. Do visual targets elicit N2pc without concurrent distractors? No, but they do elicit visual orienting activity (VOA).

Paraphrased excerpt from significance statement: Here, we disentangled visually guided orienting activity from sensory activity using ERPs. A neural index of visually guided attention orienting was identified.

Here are some results from a seminal paper by Luck and Hillyard (1994, JEPHPP, Experiment 2). In the single-item condition, there was some early lateralized activity that was chalked up to sensory imbalance. But might it be something else? An early N2pc, perhaps?
