A minority of people (Aphantasics) report an inability to visualise. Aphantasia has been linked to Autism – a neurodevelopmental condition affecting social interactions. There is a risk of a circular logic informing proposed links, as the most popular metric of autistic traits, the Autism-Spectrum Quotient (AQ), has an Imagination subscale with items relating directly and indirectly to imagery. We tested for inter-relationships between imagery vividness ratings and the expression of autistic traits, using metrics that do and do not encompass an Imagination subscale. We also conducted hierarchical linear regression analyses to assess the contributions of different AQ subscale scores to imagery inter-relationships. Only in our highest-powered study (N = 308) were we able to detect a weak inter-relationship between AQ scores and imagery, independent of the Imagination subscale. We suggest that only a weak inter-relationship should exist, as many autistic people describe themselves as visual thinkers who have strong imagery.

Yoshimori Sugano
This online experiment aimed to replicate Sugano’s (2021) findings on how exposure to delayed auditory feedback affects feeling of control (agency). Participants first adapted by repeatedly reproducing a sequence of seven, eight or nine tones on a single trial basis while receiving either immediate (10 ms) or delayed (110 ms) auditory feedback on their keypresses. This exposure aimed to recalibrate their timing perception. Following adaptation, they reproduced the sequence again. However, the computer would assume control of the tone pips starting with the fourth pip from the participants with 50 % probability, presenting them at a fixed interval (the average of the first three participant-initiated tones). Participants judged either whether their keypresses caused the tones (agency judgment: AJ) or if the tones felt synchronized with their keypresses (simultaneity judgment: SJ). Analyses revealed similar shifts in both judgments after exposure to delay, however, the AJ exhibited a greater shift compared to the SJ. In addition, the shift reflects a change in bias, not in sensitivity. The result aligns with Sugano’s (2021) in-person study, suggesting online experiments can effectively explore agency.

Decision confidence plays a critical role in humans’ ability to make adaptive decisions in a noisy perceptual world. Despite its importance, there is currently little consensus about the computations underlying confidence judgements in perceptual decisions. To better understand these mechanisms, we addressed the extent to which confidence is informed by a naturalistic prior distribution. Contrary to previous research, we did not require participants to internalise parameters of an arbitrary prior distribution. We instead used a novel psychophysical paradigm leveraging probability distributions of low-level image features in natural scenes, which are well-known to influence perception. Participants reported the subjective upright of naturalistic image patches, targets, and then reported their confidence in their orientation responses. We used computational modelling to relate the statistics of the low-level features in the targets to the average distribution of these features across many naturalistic images, a prior. Our results showed that participants’ perceptual and importantly, their confidence judgments aligned with an internalised prior for image statistics. Overall, our study highlights the importance of naturalistic task designs that capitalise on existing, long-term priors to further understand the computational basis of confidence.

Asking participants to Think Aloud is a common method for studying conscious experience, but it remains unclear whether this approach alters thought qualities—such as meta-awareness, rate of topic shifts, or the content of thoughts in task-absent conditions. To investigate this, we conducted two studies comparing thinking aloud to thinking silently. In Study 1, 111 participants alternated between 15-minute intervals of verbalizing and silently reflecting on their stream of consciousness in a counterbalanced design. A subset also reported topic shifts intermittently via self- and probe-catching methods. Results showed that the stream of consciousness was minimally reactive to the Think Aloud protocol, with no significant differences in meta-awareness and topic shifting rates. Moreover, among 21 thought qualities and 18 content topics analyzed, only three qualities (private thoughts, mind blanking, and session difficulty) and one topic (partner, intimacy, love, and sexual matters) differed between Think Aloud and Silent Think. In Study 2, 102 participants either did Think Aloud or Silent Think while responding to thought probes. Findings replicated the lack of differences in the frequency and meta-awareness of topic shifts between Think Aloud and Silent Think. Furthermore, no differences in reported cognitive load were observed between the two conditions. These results emphasize the value of the Think Aloud procedure for examining the stream of consciousness, demonstrating its reliability and minimal impact on the natural flow of thoughts. Thus, Think Aloud offers a robust model system for examining the otherwise unverbalized stream of consciousness in task-absent contexts.

Psychedelic drugs offer valuable insights into consciousness, but disentangling their causal effects on perceptual and high-level cognition is nontrivial. Technological advances in virtual reality (VR) and machine learning have enabled the immersive simulation of visual hallucinations. However, comprehensive experimental data on how these simulated hallucinations affects high-level human cognition is lacking. Here, we exposed human participants to VR panoramic videos and their psychedelic counterparts generated by the DeepDream algorithm. Participants exhibited reduced task-switching costs after simulated psychedelic exposure compared to naturalistic exposure, consistent with increased cognitive flexibility. No significant differences were observed between naturalistic and simulated psychedelic exposure in linguistic automatic association tasks at word and sentence levels. Crucially, visually grounded high-level cognitive processes were modulated by exposure to simulated hallucinations. Our results provide insights into the interdependence of bottom-up and top-down cognitive processes and altered states of consciousness without pharmacological intervention, potentially informing both basic neuroscience and clinical applications.

The encoding of episodic memories depends on segmentation; memory performance improves when segmentation is available and performance is impaired when segmentation is absent. Indeed, for episodic memories to be created, the encoding of information into long-term memory requires the experience of event boundaries (i.e., context-shifts defined by salient moments of change between packets of to-be-learned stimuli). According to this view episodic encoding, and therefore learning, is critically dependent on the nature of working memory. Motived by this theoretical framework, here we explore the effects of segmentation on long-term memory performance, investigating the possibility of optimising learning by aligning the presentation of stimuli to the capacity of working memory. Across two experiments, we examined whether manipulating the boundaries between events influences memory. Participants travelled within a virtual environment, with spatial–temporal gaps between virtual locations providing context-shifts to segment sequentially presented lists of words. Both accurate recall and memory for temporal order improve and the number of falsely recalled words reduces when reducing the quantity of information presented between boundaries. Taken together, the present results suggest that closely matching the quantity of information between boundaries to working memory capacity optimises long-term memory performance.

Sound-induced flash illusion (SiFI) is an auditory-dominant multisensory illusion that can be used to assess multisensory integration. Although previous studies have shown that one-time intervention exercise training does not significantly affect SiFI, the long-term improvement of SiFI with exercise training remains controversial. In the present study, the classical SiFI paradigm was used to investigate the effects of long-term exercise training on the SiFI. Differences in SiFI among the skill exercise, physical exercise, and control groups were also assessed. The results showed that SiFI was lower in both the skill group and the physical group than in the control group (Experiment 1), and the skill group had a lower SiFI than the control group because the skill group had a finer temporal binding window of multisensory integration (Experiment 2). In addition, previous studies have shown that brain plasticity in athletes of open skill exercises is predominantly in the cerebellum and that exercise skill learning is associated with cerebellar neuroplasticity. Therefore, we used transcranial direct current stimulation (tDCS) to modulate the cerebellum to examine whether the cerebellum was involved in SiFI (Experiment 3). The results showed that the cerebellum was involved in the SiFI, and the reduction in the SiFI in the skill group was due to the increase in developed cerebellar function resulting from long-term skill training. These results suggest that long-term skill exercise training is effective at preventing SiFI, and the present study provides empirical support for intervention training in the area of multisensory integration.

Items held in visual working memory (VWM) influence early visual processing by enhancing memory-matching visual input. Depending on current task demands, memory items can have different priority states. Here, we investigated how the priority state of items in VWM affects two key aspects of early visual processing: access to visual awareness and attention allocation. We used three perceptual tasks: the breaking continuous flash suppression task (Experiment 1), the attentional capture task (Experiment 2), and a visual search task (Experiment 3). We found that stimuli matching prioritized VWM items yielded a large perceptual advantage over stimuli matching non-prioritized VWM items (despite minimal memory loss). Additionally, stimuli matching non-prioritized memory items exhibited a (small but consistent) perceptual advantage over VWM-unrelated stimuli. Taken together, observers can flexibly de-prioritize and re-prioritize VWM contents based on current task demands, allowing observers to exert control over the extent to which VWM contents influence concurrent visual processing.

Free-choice behavior is unique in that actions are internally self-determined, unlike forced-choice behavior, which is externally specified. Several studies suggest these two action modes can lead to different behavioral, affective, and motivational outcomes. We examined whether people estimate free-choice differently from forced-choice processing time due to possible introspective biases associated with these modes. Consistent with previous studies, free choices were slower than forced choices and action mode interacted with perceptual difficulty. Importantly, all effects in mean reaction times (RTs) were mirrored in mean introspective RTs (iRTs). Moreover, objective RTs alone could essentially predict iRTs without any contributing distortion of choice modes. Thus, introspection about RT appears equally accurate for both externally and self-determined actions, suggesting that iRTs are primarily based on a direct read-out of temporal information. Possibly, accurate introspection about processing time is a crucial basis for potentially distinct subjective experiences of free and forced choices.

For millennia, humans have created drawings as a means of externalizing visual representations, and later, to aid communication and learning. Despite its cultural value, we understand little about the cognitive states elicited by drawing, and their downstream benefits. In two preregistered experiments, we explored these states; Undergraduate participants (Ns = 69, 60) encoded words by drawing or writing, periodically describing their thoughts using multi-dimensional experience sampling, a tool for characterizing the features of ongoing thought. Subsequent memory was tested via free recall. Contrasted with writing, drawing improved memory, and evoked thoughts that were more visual and elaborative. Recall was also dictated by the emergence of these thought patterns, with the former most important when drawing. Our findings establish that drawing elicits unique thought patterns that promote successful memory, providing an explanation for drawing’s influential role in our everyday lives.

Despite its cultural value, we understand little about the cognitive states elicited by drawing, and their downstream benefits. In two preregistered experiments, we explored these states; Undergraduate participants (<em>N</em>s = 69, 60) encoded words by drawing or writing, periodically describing their thoughts using multi-dimensional experience sampling, a tool for characterizing the features of ongoing thought. Subsequent memory was tested via free recall. Contrasted with writing, drawing improved memory, and evoked thoughts that were more visual and elaborative. Recall was also dictated by the emergence of these thought patterns, with the former most important when drawing.
