Do psi researchers and skeptics think alike?

Psi phenomena, such as extra-sensory perception and post-mortem survival, that are not explained by known cognitive, neural, or physiological processes, have generated interest and curiosity, but also controversy. Cognitive styles related to evaluating evidence and reaching conclusions are relevant to the controversial nature of psi, as they provide a deeper look into how different groups approach the psi phenomena. The research team, led by Marieta Pehlivanova, compared the cognitive styles, precisely the actively open-minded thinking (AOT) and the need for closure (NFC), of 144 participants divided into four groups: academic psi researchers, lay individuals who believe in psi, academics who are skeptics of psi, and lay individuals who are skeptics. On the one hand, they observed that academic psi researchers demonstrated high levels of AOT, like academic and lay skeptics, and the lay psi group had lower levels of AOT than the other groups. On the other hand, no significant differences in NFC were found among the groups, and academic psi researchers exhibited high psi belief levels comparable to lay believers. These findings suggest that despite their high belief in psi phenomena, psi researchers have a need for certainty and to collect evidence to support reasoning as skeptics. This study was developed within the scope of the research project 212/20 - Comparing cognitive styles among parapsychology researchers, psi-believers, and skeptics, supported by the BIAL Foundation, and published in the scientific journal Frontiers in Psychology, in the article Cognitive styles and psi: psi researchers are more similar to skeptics than to lay believers.

What are the effects of expectation on face perception and its relationship with expertise?

In the scope of the research project 129/20 - Investigating the role of expertise in the predictive coding framework combining time resolved neural and behavioural evidence, supported by the BIAL Foundation, Marie Smith and colleagues, through a behavioural categorization task in which 67 participants learned the probabilistic association between a colour cue and a high and low expertise category (faces and cars respectively), they assessed the individual level of expertise in each category. They found that the perception of the high expertise category (faces) was modulated by expectation. That is, there was a faster response when the faces were expected. Furthermore, in the analysis of neural activity (EEG), there were effects of expectation, with significant decoding of the neural response to expected stimuli. These results support the influence of expectation on face perception, highlight the role of expertise and draw attention to individual variability, which is often neglected. More information is available in the article Effects of expectation on face perception and its association with expertise published in the scientific journal Scientific Reports.

Is the ability to inhibit actions influenced by emotional stimuli?

The ability to inhibit ongoing motor actions is essential to avoid detrimental consequences. Effective inhibition depends mainly on the functioning of several areas, such as the pre-supplementary motor cortex (pre-SMA). The research team, led by Sara Borgomaneri, explored possible changes in the ability of 66 participants to inhibit actions upon facing emotionally negative or neutral human body postures, presented in a stop signal task, before and after the application of a session of repetitive transcranial magnetic stimulation (rTMS) over the pre-SMA, the right inferior frontal gyrus (rIFG) and the left primary motor cortex (lM1). They observed a shorter reaction time to emotionally negative stimuli after applying an inhibitory rTMS session to the pre-SMA. On the other hand, there was a shorter reaction time to neutral body postures after administration of rTMS over rIFG. No significant changes were observed after lM1 stimulation. These results support the existence of emotional effects on motor control systems and provide evidence that such effects may involve separate and distinct neural pathways from those associated with motor inhibition in neutral contexts. This study was developed within the scope of the research project 33/22 - The influence of emotions on actions: Boosting brain network plasticity to improve action control, supported by the BIAL Foundation, and published in the scientific journal Annals of the New York Academy of Sciences, in article The role of pre-supplementary motor cortex in action control with emotional stimuli: A repetitive transcranial magnetic stimulation study.

Effects of a web-based mindfulness intervention

In the scope of the research project 104/18 - Effect of mindfulness on EEG brain activity for cognitive and psychological well-being in the elderly, led by Samantha Galluzzi, the research team aimed to assess both short and long-term cognitive, psychological, and physiological outcomes of an adapted 8-week mindfulness-based intervention (MBI) delivered through live web-based videoconferencing among a group of healthy older adults. The findings, published in BMC Geriatrics, in the article Cognitive, psychological, and physiological effects of a web-based mindfulness intervention in older adults during the COVID-19 pandemic: an open study indicate that participants improved in various domains, including verbal memory, attention switching and executive functions, interoceptive awareness, and rumination both pre-to-post MBI and at 6-month follow-up (T6). Notably, the most significant changes, with medium effect sizes, were observed in immediate verbal memory and self-regulation in interoceptive awareness, and these improvements were sustained at T6. Furthermore, the study revealed changes in EEG alpha1 and alpha2 activity modulation, which correlated with improvements in attention switching, executive function and rumination.

Does autosuggestion modulate our reality?

Autosuggestion posits that individuals can influence their own mental and physiological states through the repetition of a thought, a so-called suggestion. The research team led by Elena Azañón tested whether autosuggestion can alter participants’ somatosensory perception at the finger. In three separate experiments, participants were asked to modulate the perceived intensity of vibrotactile stimuli at the fingertip through the inner reiteration of the thought that this perception feels very strong (Experiment 1, n = 19) or very weak (Experiments 2, n = 38, and 3, n = 20), while they were asked to report the perceived frequency. Notably, an increase in the intensity of vibrotactile stimuli, keeping the frequency constant, can lead either to an increase or a decrease in its perceived frequency. Whereas the direction of this effect is different between people, it is usually constant within one individual and can therefore be used to test for the effect of autosuggestion in a within-subject design. It was observed that the task to change the perceived intensity of a tactile stimulus via the inner reiteration of a thought modulates tactile frequency perception. This study was conducted in the scope of the research project 296/18 - The power of mind: Altering cutaneous sensations by autosuggestion, supported by the BIAL Foundation, and published in the paper How the inner repetition of a desired perception changes actual tactile perception in the journal Scientific Reports.

The quest of physiological markers for the experience of pain

Researcher: Elia Valentini - Department of Psychology & Centre for Brain Science, University of Essex Summary: The aim of this project is to improve measurement of the human experience of pain by investigating a combination of psychophysical and physiological responses during mild noxious stimulation. More specifically, we want to investigate how sensitive and specific to pain the brain oscillatory responses are. We use EEG as the main technique, but we are keen to collaborate with neuroscientists using fMRI, autonomic measures and brain stimulation as well as with computational neuroscientists. A clinical collaborator would also be very much welcome.

EEG investigation of hypnosis and decision-making

Researcher: Rinaldo Livio Perri - University Niccolò Cusano Rome, Italy Summary: I work in the field of hypnosis and cognitive neuroscience. In particular, I adopt the event-related potentials (ERPs) to investigate the effect of the hypnotic suggestions on sensory processing and cognitive performance. I am an expert in decision-making and proactive brain processes before the stimulus administration (e.g., the perceptual, prefrontal and premotor readiness during the expectancy stage). I could help colleagues to properly analyze the ERP signal in the pre-stimulus stage of processing. Also, I would be happy to share my EEG data for re-analyzing them in the frequency domain (e.g., wavelet or coherence analysis in the hypnosis research). Feel free to contact me for any question!
