This Master gave everything a perfunctory glance as it passed through. Off the receiving room was the transfer chamber itself: two long metal tables, a tile floor set with drains, elegant mirror-glass walls which were easy to wash and sterilize. Through the open doorway Sadie could see that Enri had already been strapped to the left table, facedown with arms outstretched. His head was buckled in place on the chinrest, but in the mirrored wall his eyes shifted to Sadie. There was nothing of anticipation in that gaze, as there should have been. He knew to be afraid. Sadie looked away and bowed at the door as the Master passed.
She had. But she could not bring herself to say so, because just thinking it made her hurt all over inside, like shaking apart, and the dream was fragile. Too much of anything would break it; she could feel that instinctively.
They had reached a hill, which overlooked a landscape that Sadie had never seen before: meadows and hills in a vast expanse broken only occasionally by lone trees, and in the distance a knot of thick variegated green. Was that a . . . jungle? A forest? What was the difference? She had no idea.
She had never let herself imagine this. Never, not once. These were the dangerous thoughts, the ones that threatened her ability to keep doing what the Masters wanted or to keep from screaming while she did those things. If she even thought the word free, she usually made herself immediately think about something else. She should not be dreaming about this.
Olivia flinched, then turned and walked stiffly away. Sadie gazed after her for a long while, first trembling as the anger passed, then just empty. Eventually she went back into the transfer room to clean up.
The scene before her changed. Now there were people moving among the sinks and machines. Their bodies were clothed from head to toe in puffy white garments, their heads covered with hoods. They scurried about like ants, tending the sinks and machines, busy busy busy.
A snarl and thump behind her. She spun, her heart pounding, to find that the opulent chamber now held people. Four men and women in neat black uniforms, wrestling a struggling fifth person onto the wooden desk. This fifth man, who was portly and in his fifties, fought as if demented. He punched and kicked and shouted until they turned him facedown and pinned his arms and legs, ripping open his clothing at the back of the neck.
She felt empty inside. The emotion that had driven her to attack the Masters was gone, replaced only by weariness. Still, she remembered the desperate struggles of the captured man in her dream. Like Enri, that man had faced his final moments alone.
And there was something about this chaos, something so subtly counter to everything she knew about the Masters, that she understood at once these were people without Masters. They had built the vehicles and they had built the roads. They had built the whole city.
She told Caridad to run ahead and open the transfer chamber, and signed for Olivia to grab one of the children; any healthy body was allowed in an emergency. The Master was still alive within its old, cooling flesh, but it would not be for much longer. When the Masters reached the administrative level, Sadie quickly waved it toward the transfer chamber, pausing only to grab something from her cubicle. She slipped this into the waistband of her pants, and followed at a run.
Across this series of experiments, we observed no significant effect of doorways on forgetting. In Experiment 2, however, signal detection was impaired when participants responded to probes after moving through doorways, such that false alarm rates were increased for mismatched recognition probes. Thus, under working memory load, memory was more susceptible to interference after moving through doorways.
This study presents evidence that is inconsistent with the location updating effect as it has previously been reported. Our findings call into question the generalisability and robustness of this effect to slight paradigm alterations and, indeed, what factors contributed to the effect observed in previous studies.
Our experience of the world is continuous and rich with information. To manage this constant stream of information, we segment our experience into events, which are stored as episodic memory for later retrieval [22]. Events are determined by boundaries, denoting the beginning and end of a particular period of time. Salient environmental changes are thought to dictate the location of event boundaries (e.g., a change in location, a shift in goal, etc.; [23].
Numerous iterations of this experiment have explored the robustness of the doorway effect. These studies have found that the effect persists regardless of the type of probe (text vs. images [18], recognition vs. recall [10]), travel time [8, 9], the level of immersion (small screens, big screens, or real-life environments [16]; active vs. passive interaction; [11], real or imagined; [6, 12]), age [17], whether the dividing wall is transparent or opaque [8], whether there were additional items to remember [18], or whether participants were probed after returning to the room the item was first encoded in [16].
The aim of Experiment 1 was to conceptually replicate the original study demonstrating the doorway effect [15] under controlled conditions. We increased immersion by using a full virtual reality headset and designed the virtual environment so that all rooms were visually identical, as opposed to previous studies [15] where the walls were different colours. Thus, in our experiment, any forgetting could only be attributed to boundaries rather than salient changes in context or visual processing. We also more than doubled the number of trials (51 trials to 110) so as to maximise statistical power. We hypothesised that, if the doorway effect is indeed solely attributable to door boundaries rather than extraneous experimental factors, we would observe impaired recognition memory in the form of fewer hits and more false alarms.
For Experiment 2, we recruited 63 first-year psychology students from the University of Queensland who received course credit for their time. All participants provided written consent and were required to have normal or corrected-to-normal vision and normal colour vision. Of the 63 participants, 14 aborted the experiment due to motion sickness, and 4 participants were excluded due to poor performance (
Two similar virtual environments (one map per block) were created using Unreal Engine 4 (Epic Games, 2019). Participants viewed the environment with an HTC Vive Headset and interacted with the environment using left and right HTC Vive wireless controllers.
To address the ceiling effect observed in Experiment 1, we introduced a distractor task that would interfere with object memorisation and thus encourage forgetting. After picking up the object and releasing the trigger (initiating movement), participants had to verbally count backwards, in sixes, from a random number provided by the experimenter until the probe screen appeared. Hence, this task increased working memory load during the period between interacting with the objects on the table to being probed by the question screen.
Overall, the findings from Experiment 2 suggest that, under conditions of working memory load during memorisation time, doorways do impair mnemonic performance but not due to forgetting (i.e., fewer hits and more misses, as typically reported by previous research [15]). Instead, doorways increased the false alarm rate to negative probes.
In Experiments 3 and 4, we aimed to conceptually replicate previous experiments that demonstrate the doorway effect in real life contexts [16]. Experiment 3 consisted of passively watching a video from a first-person perspective of someone traversing a corridor with or without curtain boundaries (see Fig. 2). Experiment 4 involved active navigation through the same corridor. The curtain set-up closely resembled that used by a previous study demonstrating the doorway effect during imagined navigation [6]. Also, similar to previous real-life investigations into the doorway effect [6, 10, 12, 16], we increased working memory load demand (counting task) and had participants memorise multiple items to increase task difficulty. We hypothesised that, should the doorway effect be robust to even impermanent boundaries (e.g., curtains) and returning to the original context (as has been shown previously [16]), then participants would demonstrate impaired memory performance after crossing a boundary.
In Experiment 3, participants were seated in a dark room on a swivel chair at a desk upon which the 16 butterfly stimuli were arranged in a specific grid layout (one of the 25 layouts). After the lights were turned on (revealing the stimuli on the desk), participants were given 30 s to memorise the location of each different butterfly in the grid. After 30 s, the lights were turned off and participants were required to spin their chair around to face an open laptop on a desk behind them. The participant then used the laptop track pad to press play on the video of the hallway walk. Participants were encouraged to imagine they were the person walking down the hallway. Like in Experiment 2, participants were also required to count backwards out loud in decrements of 3 from a random number between 90 and 100 (provided by the experimenter). While the participant watched the video, the experimenter stacked and shuffled the photographs behind the participant. After the video ended, the lights were turned back on. To ensure participants paid attention during the video, the experimenter asked the participant whether they had turned left or right at the end of the hallway (all participants answered 100% correctly). After this, participants were given 45 s to rearrange the butterflies into the grid formation they had memorised. Overall, there were 24 trials that alternated between the shift and no shift condition (the starting condition was counterbalanced across participants).
