Abstract/Results: ABSTRACT:
Size aftereffects are a compelling perceptual phenomenon in which we perceive the size of a stimulus as being different than it actually is following a period of visual stimulation of an adapter stimulus with a different size. Here, we used continuous flash suppression (CFS) to determine if size aftereffects require a high-level appraisal of the adapter stimulus. The strength of size aftereffects was quantified following a 3-s exposure to perceptually visible and invisible adapters. Participants judged the size of a target that followed the adapter in comparison to a subsequent reference. Our experiments demonstrate that the adapter no longer influenced the perceived size of the subsequent target stimulus under CFS. We conclude that the perception of size aftereffects is prevented when CFS is used to suppress the conscious awarness of the adapting stimulus.

Abstract/Results: ABSTRACT:
Our understanding of how form, orientation and size are processed within and outside of awareness is limited and requires further investigation. Therefore, we investigated whether or not the visual discrimination of basic object features can be influenced by subliminal processing of stimuli presented beforehand. Visual masking was used to render stimuli perceptually invisible. Three experiments examined if visible and invisible primes could facilitate the subsequent feature discrimination of visible targets. The experiments differed in the kind of perceptual discrimination that participants had to make. Namely, participants were asked to discriminate visual stimuli on the basis of their form, orientation, or size. In all three experiments, we demonstrated reliable priming effects when the primes were visible but not when the primes were made invisible. Our findings underscore the importance of conscious awareness in facilitating the perceptual discrimination of basic object features.

Abstract/Results: ABSTRACT:
We investigated if the subliminal processing of threatening animal (snakes and spiders) and neutral object (cars and houses) stimuli can influence the discrimination of a subsequent visible stimulus. The prime and target pair were either identical, of the same category but with different physical features, or different in category and physical features. In two experiments, participants discriminated the basic level category (e.g. snake vs. spider) of a visible target stimulus that had been preceded by a visible or perceptually invisible prime stimulus. One experiment used visual masking to render prime stimuli perceptually invisible and the other used continuous flash suppression (CFS). Priming effects were demonstrated in both experiments when the prime was visible but not when the prime was rendered perceptually invisible. These findings demonstrate that conscious awareness could be required in the perceptual discrimination of threatening animal and neutral object images at their specific basic level category.

Abstract/Results: ABSTRACT:
We applied continuous flash suppression (CFS) during an interocular transfer paradigm to evaluate the importance of awareness and the contribution of early versus late visual structures in size recognition. Specifically, we tested if size judgements of a visible target could be influenced by a congruent or incongruent prime presented to the same or different eye. Without CFS, participants categorised a target as “small” or “large” more quickly when it was preceded by a congruent prime – regardless of whether the prime and target were presented to the same or different eye. Interocular transfer enabled us to infer that the observed priming was mediated by late visual areas. In contrast, there was no priming under CFS, which underscores the importance of awareness. We conclude that awareness and late visual structures are important for size perception and that any subconscious processing of the stimulus has minimal effect on size recognition.

ABSTRACT:
What is and what is not processed outside of conscious awareness is currently being increasingly investigated as the field begins to appreciate and understand more the involvement of different visual pathways in the brain. Our project aimed to determine the degree to which different object characteristics and objects are processed subconsciously relative to when they are processed consciously and to determine the contribution of the lateral occipital complex (LOC) during these processes. Several behavioural experiments were carried out. The experiments used continuous flash suppression (CFS) and more traditional visual masking paradigms to examine if the form, size, and orientation of objects, as well as words and emotionally salient stimuli, could be processed outside of conscious awareness. These experiments revealed that words and emotionally salient stimuli are processed outside of conscious awareness but not the most basic feature of objects, including their form, size and orientation, at least within the context of visual perception. Our functional magnetic resonance imaging (fMRI) experiment further revealed that LOC contributes to the processing of these features during conscious awareness. Taken together, our findings indicate that it is unlikely that it does so outside of conscious awareness. It seems that consciousness awareness is required for processing the basic features of objects, such as their form, size, and orientation, for perceptual purposes.

The processing of images of spiders and snakes outside of conscious awareness under visual masking

Abstract/Results: ABSTRACT:
The brain is constantly surveying and selecting relevant visual stimuli to attend to. However, it has been suggested that stimuli with emotional salience (e.g., images of spiders and snakes) can bypass this processing and be processed outside of conscious awareness. To explore this possibility, two experiments were completed in which participants were presented with images of spiders and mushrooms (Experiment 1; N = 35), or snakes and flowers (Experiment 2; N = 35). These images were presented under visible (i.e., the participant was able to perceptually see the images) or invisible (i.e., a visual-masking technique was used to render the images perceptually invisible) conditions. Each experiment had two tasks. In the recognition task, the participant’s Galvanic skin response (GSR) was recorded when viewing visible and invisible stimuli. In the priming task, the participant’s reaction time was measured to a visible target stimulus preceded by either a visible or invisible prime stimulus that was either congruent or incongruent. There were no differences in GSR between conditions in the recognition task for either experiment. In the priming task, there were significant Visibility × Congruency interactions in the spider, F(1,32) = 9.47, p = .004, and snake, F(1,33) = 17.46, p < .001, experiments. Pairwise comparisons, correcting for multiple comparisons using the Bonferroni method, revealed that priming occurred in both visibility conditions with stronger effects for the visible (Experiment 1 Cohen’s d = 1.22; Experiment 2 Cohen’s d = 1.25) compared to invisible (Experiment 1 Cohen’s d = 0.59; Experiment 2 Cohen’s d = 0.53) conditions. Results from the recognition task suggest that there is no difference in the physiological response to the processing of different stimuli. However, in the priming task, results suggest that the invisible stimuli were processed outside of conscious awareness. This suggests that conscious awareness may enhance but is not always required to process certain visual stimuli.

The mechanisms of size perception inferred by continuous flash suppression and interocular transfer

Abstract/Results: ABSTRACT
Early visual structures, like the primary visual cortex (V1), have an active role during size perception. We examined interocular transfer in a priming task both within and outside of awareness using continuous flash suppression (CFS). Specifically, stimulus sequences in which a prime and target that were either size-congruent or size-incongruent could be presented in succession to the same eye (monocular condition) or separately to each eye (dichoptic condition). This design enables one to infer the relative contributions of early and later visual structures, as monocular channels remain segregated in early visual areas (like V1 and earlier), but begin to coalesce in the cortex (V1 and beyond). Thus, equivalent reaction times across same and different eye presentations (i.e., interocular transfer) would highlight the importance of later visual areas. Thirty-five participants (Mage = 25.2 years) completed the experiment. Participants categorised a target stimulus as either small or
large. Trials varied prime visibility (CFS vs. visible), prime and target congruency (congruent vs. incongruent size), and eye presentation (monocular vs. dichoptic). A three-way ANOVA revealed a Congruency × Visibility interaction, F(1, 34) = 6.08, p = .02, ?2 p = .15, which was driven by priming effects in the visible (p < .05, d = .25, BF10 = 18.45) but not CFS (p = .99, d = .03, BF10 = 0.23) conditions. There was also an Eye × Visibility interaction, F(1, 34) = 17.10, p < .01, ?2 p = .34, which was driven by a monocular advantage under CFS (p < .01, d = .36, BF10 = 91.25), whereas monocular and dichoptic presentations were equivalent during the visible condition (p = .97, d = .03, BF10 = .21). Taken together, priming effects in the visible but not CFS conditions suggest that awareness is an enabling factor for size perception to occur. Further, we can infer that this is likely mediated by later visual structures, as there was complete interocular transfer of the size information.

Abstract/Results: ABSTRACT:
There is some evidence for the unconscious processing of emotional stimuli (particularly aversive), which is thought to serve an adaptive purpose. However, results in the research literature have been inconsistent. This psychophysical study examined the subconscious processing of aversive (snakes and spiders) and neutral (cars and houses) images using a priming paradigm. Two experiments were
conducted in which the awareness of a priming stimulus was suppressed in half of the trials using either visual masking (Expt 1; N =16) or continuous flash suppression (Expt 2; N =16). Participants
were tasked with discriminating the proceeding target stimulus using a 2-alternative forced choice method. Reaction times (RTs) to this stimulus were recorded.
Expt 1: ANOVA demonstrated a three-way interaction for Valence
(Aversive vs Neutral), Visibility (Visible vs Masked), and Priming Condition [Different Class (e.g. snake followed by spider) vs Different Exemplars (e.g. snake followed by different snake) vs Same Exemplar (e.g. same snake repeated)] (F(2,30) = 9.66, p < .001). This result was driven by faster RTs for Same Exemplar pairs in comparison to Different Class and Different Exemplar pairs, but only in the Visible condition. Aversive stimuli were found to have slower reaction times than Neutral stimuli but only in the Visible, Different Class condition.
Expt 2: ANOVA demonstrated a two-way interaction between Visibility and Priming Condition (F(2,30) = 19.88, p < .001). Similar to Expt 1, faster RTs were found for Same Exemplar pairs in comparison to Different Class and Different Exemplar pairs in the Visible condition. This priming effect was not found in the Masked condition. There were no interactions or main effects of Valence.
Given we have been unable to demonstrate evidence of priming in both the visual masking and CFS experiments, we conclude that the visual processing of aversive and neutral images is greatly facilitated by awareness.

Abstract/Results: ABSTRACT:
It is widely assumed that subliminal word priming is case insensitive and that a short SOA (<?100 ms) is required to observe any effects. Here we attempted to replicate results from an influential study with the inclusion of a longer SOA to re-examine these assumptions. Participants performed a semantic categorisation task on visible word targets that were preceded either 64 or 192 ms by a subliminal prime. The prime and target were either the same or different word and could appear in the same or different case. We confirmed the presence of subliminal word priming (same word?<?different word reaction times). The word priming effect did not differ when case was the same or different, which supports case insensitive word priming. However, there was a general facilitation effect driven by case (same case?<?different case). Finally, there was a significant difference between the two SOA conditions; however, there were no interactions between SOA and any other factor, demonstrating that subliminal priming did not differ between short and long SOAs. The results demonstrate that word priming is case insensitive but that there is nevertheless an overall facilitation when words, regardless if they are repeated or not, are presented in the same case. This facilitation in case may reflect modularity in the low-level processing of the visual characteristics of words.

BIAL Foundation Archive
Start date: 1994
History:
The BIAL Foundation was created in 1994 by Laboratórios BIAL in conjunction with the Council of Rectors of Portuguese Universities. BIAL’s Foundation mission is to foster the scientific study of Man from both the physical and spiritual perspectives.
Along the years the BIAL Foundation has developed an important relationship with the scientific community, first in Portugal and after worldwide. Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Title:
fMRI form adaptation and size repetition enhancement in different subdivisions of the lateral occipital complex
Publication year: 2022

Abstract/Results: Research findings on which brain areas demonstrate fMRI adaptation to the form, orientation, and size of visual stimuli has been mixed. Studies demonstrate effects in various subdivisions of the lateral occipital complex (LOC), including retinotopically tuned areas LO-1 and LO-2, and dorsal stream areas in the intraparietal sulcus (IPS). Therefore, we aimed to examine fMRI adaptation in four subdivisions of the LOC (LO-proper, posterior fusiform sulcus, LO-1, and LO-2) and three discrete regions in the IPS (caudal IPS, IPS-proper, and anterior IPS) to clarify the role that these structures play in form, orientation, and size processing. Participants performed three tasks which involved judging whether two serially presented novel objects shared the same form, orientation, or size. On each version of the task, one feature varied from trial-to-trial (e.g., form) while the other two features (e.g., orientation and size) were held constant. In this way, we were able to examine the unique fMRI signal changes in response to changes in form, orientation, and size in isolation. Form adaptation – a decrease in fMRI signal following repeated presentation of the same stimulus – was present in LO-proper and pFS, highlighting the role of LOC in form processing. Size repetition enhancement – an increase in fMRI signal following repeated presentations of the same stimulus – was observed in pFs. We propose that the latter result demonstrates the effects that top-down factors can have on visual areas, specifically when there is stimulus uncertainty. There was no evidence of orientation processing in any of the regions examined. Neither form adaptation nor size repetition enhancement was present in the three IPS regions-of-interest. Last, retinotopically defined LO1 and LO2 could not be reliably identified in participants and therefore we were unable to examine adaptation in these areas as we originally intended to do.
