Abstract/Results: RESULTS:
In this Project, we have investigated memory mechanisms in the human visual system, by employing a combination of psychophysics and functional magnetic resonance imaging (fMRI) methodologies to identify the neural correlates of different types of learning processes. For this purpose, we implemented and optimized a number of fMRI visual mapping paradigms in order to identify the visual brain areas of interest.
We first observed the adaptive functional reorganization of visual memory in a population of temporal lobe epilepsy patients with right unilateral hippocampal sclerosis. We used fMRI to measure brain activity changes during the episodic encoding of abstract line drawings and found that the patients engaged the left hippocampus more than controls and that the level of engagement was correlated with their memory recognition scores. These finds suggested functional reorganization of visual memory with an adaptive role, as a consequence of prolonged disease. We also found that familiar items activated visual cortical areas more than novel items, suggesting a reinstatement of visual information as a consequence of learning.
In a second study, we implemented a visual learning paradigm whereby subjects performed a face discrimination task on faces presented in multiple orientations, in order to investigate the hypothesis that the human visual system contains specialized processing mechanisms that are more engaged by upright faces than by inverted faces or non-face objects, as a result of extensive practice with upright faces. Our psychophysics experiments showed that participants gave more errors and were slower in their responses as faces were rotated away from 0º. In addition, performance was improved when participants underwent periods of training, both for trained and untrained orientations. Consistently with the expertise hypothesis, we also found a parametric modulation of fMRI activity in specialized visual brain areas, according to the quadratic behavioural effect of face orientation.

Abstract/Results: ABSTRACT:
Previous research had shown that processing speed and premorbid IQ are predictors of verbal-memory efficiency in patients with schizophrenia. We investigated whether the same factors are involved in visual memory. A total of 49 patients with schizophrenia and 43 healthy controls were administered a picture recognition task. Half of the pictures were black and white, and half were in color, in order to vary the depth of encoding. Processing speed was measured by three standard tasks, and premorbid IQ was measured by the National Adult Reading Test (NART). Patients were significantly impaired in picture recognition. Regression analyses revealed that NART score was a significant predictor of the recognition of both types of picture in patients. Processing speed was a significant predictor of the recognition of the colored pictures. The effect of diagnosis on the recognition of colored pictures was reduced to nonsignificance when processing speed was entered in the regression. These data suggest that premorbid IQ is involved in visual-recognition efficiency. However, the deficit observed in patients is accounted for by decreased processing speed.

Long-term memory for movie details: selective decay for verbal information at one week

Abstract/Results: ABSTRACT:
Mnemonic representations of complex events are multidimensional, incorporating information about objects and characters, their interactions and their spatial–temporal context. The present study investigated the degree to which detailed verbal information (i.e., dialogues), as well as semantic and spatiotemporal (i.e., “what”, “where”, and “when”) elements of episodic memories for movies, are forgotten over the course of a week. Moreover, we tested whether the amount of dimension-specific forgetting differed as a function of the participant's age. In a mixed design, younger and middle-aged participants were asked to watch a ~90 min movie and provide yes/no answers to detailed questions about different dimensions of the presented material after 1, 3 days, and 1 week. The results indicate that memory decay mainly affects the verbal dimension, both in terms of response accuracy and confidence. Instead, detailed information about objects/characters’ features and spatiotemporal context seems to be relatively preserved, despite a general decrease in response confidence. Furthermore, younger adults were in general more accurate and confident than middle-aged participants, although, again, the verbal dimension exhibited a significant age-related difference. We propose that this selective forgetting depends on the progressive advantage of visual compared to auditory/verbal information in memory for complex events.

Abstract/Results: ABSTRACT:
How do we visually explore and remember objects in our environment? Despite extensive research, the interplay between eye movements and visual memory remains incompletely understood. Traditional models of eye movements focus on image-specific factors like saliency and semantics, but emerging evidence highlights the role of intrinsic factors (e.g., genetic variability, endogenous dynamics). Additionally, eye movements and memory processes are tightly linked at the neural level. This study investigates the influence of eye movement spatial distribution during free exploration of visual scenes on long-term memory formation, examining whether fixation density patterns are a stronger determinant of memory than image factors. We recorded eye movements from 120 participants exploring 180 images, with five repeated five times. Participants then completed a free recall task, verbally reporting objects from the repeated images. Eye movement topography (gaze maps) demonstrated significant overlaps with memory maps, exceeding the overlap with saliency and semantics. Notably, gaze-to-memory map overlap predicted individual performance. These findings provide novel evidence that eye movement patterns contribute directly to long-term memory formation, with gaze topography serving as a critical input for encoding visual scenes. This study highlights the role of eye movements in memory and sheds light on visual exploration and memory consolidation mechanisms.
