the second talk I gave at #psynom23 looked at some preliminary results from an ALL task using sleep as the variable of interest: participants were more accurate in the sleep condition, and, once again, made different types of errors than in the non-sleep one.

in case you missed my talks at #psynom23, here are links to slides! the first talk I gave was for APCAM: participants in an artificial language learning task committed different errors in the multitalker condition than in the single talker condition.

B’bye San Francisco @Psychonomic_Soc #psynom23 so much great science! Thank you.

I had a great time at #psynom23! Very glad the rain stopped in time for a great morning walk!
Graph titled forgetting rate for all events. Line graph showing slow and steady decrease in memory from 100% for memories in sept-oct 2023 to ~60% for memories from march-may 2020
Instead of a typical Ebbinghaus logarithmic forgetting curve (sharp initial drop that flattens over time), he finds a steady & slow linear decrease in memory. This matches past diary studies. Likely due to the types of events that get chosen or the very specific & useful retrieval cues #Psynom23 End
This Nov he randomly selected 10 events per month and cued his memory with the date, title, description and thoughts. He recognized all the events (knew they happened) but had either no recall, composite recall (combo of events), partial recall or complete recall. #Psynom23 3/
Every day he recorded two events including a title, event description, his emotions/thoughts, its location, who else was there, its importance and whether it was a unique event or something that would likely repeat (eg weekly tennis match). #Psynom23 2/
March 2020 @irahyman.bsky.social started keeping an autobiographical memory diary. Planned to compare pandemic memories to post pandemic, but still no clear end. Decided after 3.5 years it was time to start looking at the data.
Each day he..

If training is probabilistic (eg source is mostly wrong), repetition from untrustworthy source still increases belief. But when source is always wrong repetition does not increase belief. Social cues can moderate (or even eliminate) the effect. #Psynom23 6/
Speaker in front of slide with true fact on green background and false statement on red background.
Next, @rmpillai.bsky.social talking about our research on how repetition increases belief. Can we disrupt this relation when the information comes from an untrustworthy source? Trained ppl through experience that Mr. Green was trustworthy and Mr. Red was untrustworthy (often wrong) #Psynom23 5/
Higher education ⬆️ climate change concerns but no effect on severe weather concerns. Direct experience w severe weather is a small predictor of climate concerns, so is indirect experience (know someone). Much stronger predictor of severe weather concerns. The two concepts are different. #Psynom23 4/
Speaker in front of slide reading climate and weather are not the same. Picture of closet with text climate is average weather over a long period. Picture of T-shirt and shorts with text weather is experienced in the moment
Next, Wandi Bruine de Bruin on public perceptions of climate vs weather. Do ppl understand how they differ? 2021 world risk poll, nationality representative samples in 121 countries (about 1000 per country) - sounds like an amazing open dataset!

Also no increase when 2 statements share same topics (e.g. two different facts about cows & teeth). But when facts have the same underlying meaning (cows have a hard dental pad for chewing instead of front teeth & cows have no front teeth) reading the first makes the 2nd feel more true #Psynom23 2/
Back at it #Psynom23! Morning session on judgment. First up is Jessica Udry discussing the effects of repetition on belief. People think repeated information is truer. But they find no increase when just the topic is repeated (e.g. first see "cows" then "cows do not have front teeth"). 1/
Today! 8:20 am PST @psychonomicsociety.bsky.social, we're part of the Cognition: Development, Embodiment and Culture session in Continental 1&2 #psynom23

I really enjoy learning about diversity, disability identity & scientific research from disabled scholars themselves at @Psychonomic_Soc #psynom23 their perspectives are needed to remove disability stigma & ensure full inclusivity and equity! Please open up to them.
Diversity and inclusion reception happening now at #Psynom23
If you're at #psynom23, come see my graduate student Katie Burnett present "Beliefs about access to offloaded information at test impacts depth of encoding" (poster #3158) in the evening poster session!
Ppl had ⬆️ memory for key possessions in basketball game that changed likely outcome (surprising moments). In 2nd study asked fans for most positive/negative memory of a single play, game and season. Again see links with surprise even for these long-term events (hours/months).

Graph of win probability for exciting game (lots of ups/downs) vs boring game (stable from beginning to end)
Final speaker James Anthony on how surprise is linked with enhanced autobiographical memory for real world events. Takes advantage of sports as a domain. Sporting events vary in their excitement and surprise and are strongly emotional and memorable for fans. #Psynom23 /10
Graphs showing Clinton supporters were less positive and more negative after election than before particularly when outcome was a surprise. Similar for Trump supporters but more positive after election.
Graphs showing memory details and coherence did not differ by political affiliation or surprise.
Report emotion before and after election, details of memory. Emotional response to the election was amplified by surprise but objective memory did not differ with political affiliation or surprise. Similar for both elections but differences in subjective memory across the two elections.
#Psynom23 /9
Next up is Kimberly Chiew talking about how expectation affects our emotional response to complex real-world events and our memory for those events. Specifically the 2016 and 2020 US elections. Retrospective report a few weeks after 2016 election, 6 mo later and 1 yr later. #Psynom23 8/
Graphs showing the lockdown period was perceived as shorter in line with temporal comprehension in memory
Also examined ppls monthly affect and how it affected later autobiographical memory retrieval. More likely to retrieve memories from months with more negative emotions. When asked to judge time of news events in 2020, think things during lockdown were closer together #Psynom23 7/
Graph showing large bump for memories in March 2020
Next up, Nina Rouhani on how reward prediction errors shape memory. Specifically, how did our collective experience of the pandemic affect our autobiographical memory. Most memories from 2020 were in March as things shut down. Memories were also more similar across ppl in March #Psynom23 6/
Slide - Take-Home Idea A message intervention can reduce the harmful effects of anxiety on learning. Surprise shapes how we learn and how we feel
Overall, students corrected more errors when feedback was surprising (confident correct but actually wrong). Anxious ppl were less likely to learn from mistakes but the positive message protected against these effects. #Psynom23 5/
Adam Barnas presents his poster today on Spatial attention cuing of spatial directions.
12pm. Come check it out! @adamjbarnas.bsky.social @psychonomicsociety.bsky.social #psynom23
On left graphs showing that shifts in emotional valence and change in the music itself impair temporal order memory. On right, shifts towards positive emotions facilitate memory integration.
When images occurred during different emotional states (eg calm/sad), ppl had impaired memory for which item was presented first as compared to when both items were seen during the same emotion. Concludes that memories are organized around emotional stability and change. #Psynom23 2/
Time for the first symposium at #Psynom23 - Temporal dynamics of affect and surprise shape laboratory and real-world memories. First up, David Clewitt looking at how emotional changes can segment memories. Ppl listened to music that shifted emotion while they studied pictures of objects. 1/
What a beautifully delivered and balanced keynote by Jennifer Eberhardt! rigorous research intertwined with personal accounts to emphasise the pervasive patterns of racial bias that continues to plague us!Thanks #psynom23 @Psychonomic_Soc
And on that note G’night, San Francisco!
