It's #ecvp poster day for our lab - one this morning, the rest this afternoon. Fun conference so far!

TLDR: In our task, we found that searchers would first use a combination of both perceived effort and time to determine what makes an object “easy” or “hard” to interact with in relation to all other objects, before prioritizing interactions with said easier objects.

Overall, we found that in line with our previous work, effort appears to be the predominant factor driving selection choices. Nevertheless, time was still an important and aversive attribute that should not be overlooked. Specifically, time became particularly aversive when paired with high effort.

We manipulated the speed and predictability of coin movements, and the duration of time participants chased coins for before they would flip. Annoying, we know!! Thus, allowing us to tease apart the interaction between time and effort and the degree to which these influence selection choices.

We had participant “chase” and “attack” virtual coins with their computer mouse. Participants needed to repeatedly click on a coin until it would “give up” and flip over. Once flipped, the coin would reveal previously hidden visual information.

New paper from our lab alert! We have just published another paper on interactive search. This time we investigated the interaction between effort and time on selection choices using a computer game inspired task. Read it here: doi.org/10.1177/1747... Or read the thread below for the gist!

We have a paper out at Behavior Research Methods. Led by Hayward Godwin, it examines sharing practices (using visual search as a case study) and makes recs for sharing data outputs in a manner that will enable others to better find, access, and understand them. link.springer.com/article/10.3...

🧵5/6 To our surprise, in Experiment 2, participants consistently prioritised interactions with information-poor cubes first. 🔍 Why? We believe that whilst less optimal, it was cognitively easier to process information-poor cubes first. In other words, effort wins again.

🧵 4/6 In Experiment 2 we focused on visual information. Cubes either contained multiple shapes (information-rich) or were predominately empty (information-poor). Our logic? Focusing on areas with a large number of potential targets would be the more optimal strategy.

🧵 3/6 In Experiment 1, half of the cubes were made to be hard to rotate, and half were easy. Our results showed that participants developed an extremely strong and consistent bias towards selecting easy cubes first. 😴 We’re wired to avoid physical effort – even in simple mouse movements.

🧵 2/6 Methods: We ran two experiments where participants rotated virtual cubes whilst trying to find a target T-shape amongst distractor L shapes. 💻 We utilised @threejs.org and @jspsych.org to make this possible. You can demo this yourself via this link! – tinyurl.com/4tz6aufs

Ever fumbled through your bag for your keys? That’s an interactive search: moving objects to uncover obscured visual information. In a new paper from our lab, we asked: What determines where people choose to look first in these tasks? Spoiler: effort matters. 🔗 doi.org/10.3758/s134... 🧵1/6
