OVERVIEW

The course, compulsory for all curricula, provides a coherent, up-to-date introduction to the basic facts and theories concerning (human) sensory perception. The physical and physiological aspects of each sensory modality are considered before its perceptual characteristics. Emphasis is placed on how perceptual experience relates to the physical properties of the world and to physiological constraints in the brain.

AIMS AND CONTENT

LEARNING OUTCOMES

Un'introduzione coerente e aggiornata ai fatti e alle teorie di base riguardanti la percezione sensoriale (umana). Il corso copre gli aspetti fisici e fisiologici di ciascuna modalità sensoriale e le sue caratteristiche percettive. L'enfasi è posta su come l'esperienza percettiva si riferisce alle proprietà fisiche del mondo e ai vincoli fisiologici nel cervello

AIMS AND LEARNING OUTCOMES

The course aims to:

  •      Provide elements on the physical and physiological basis of perception (with particular attention to the visual, auditory and somatosensory system). Sensory processes to support the control of action and behavior will be privileged.
  •      Provide the student with some theoretical and practical tools to experiment with the study of perceptual processes.
  •      Provide elements for the design of algorithms, techniques and systems to measure or influence human perception and behavior.


At the end of the course, the student will have achieved some understanding of the physical stimuli relevant to the considered sensory modalities, and a basic grasp of the underlying sensory physiology. He will also be able to design a simple psychophysical experiment and to model the receptive fields of the primary sensory areas.

PREREQUISITES

Linear algebra and analytical geometry in space.

Elements of signal processing.

TEACHING METHODS

Traditional lectures and guided practical classes on pyshophysics (48h). An 8h supplementary course on "Mechanisms of multisensory integration in health and disability" is also foreseen.

SYLLABUS/CONTENT

Part I – Neurophysiological basis of perception

  • Transduction principles, perception-action cycles.
  • Functional characterization of the main perceptual systems (visual system, auditory system, somesthetic systems).

Part II – Techniques for the analysis and interpretation of data

  • Foundations of psychophysical techniques.
  • Qualification of perceptual features.
  • Representation and analysis of multidimensional signals.

Part III – Interactive and enactive paradigms

  • Introduction to ecological perception (Gibson’s direct perception & sensorimotor theory).
  • Linking images to 3D scene properties (image formation, projective geometry, pinhole camera, homogeneous coordinates).
  • Scene reconstruction (stereoscopic geometry, parallel and vergent optical axes, geometry of the motion field).

Supplementary course (dr. Monica Gori, 8h): Mechanisms of multisensory integration in health and disability.

EXAMS

EXAM DESCRIPTION

Oral exam consisting of two short-answer questions followed by two in-depth questions.

The student who fails or withdraws from the exam cannot register for the next session.

ASSESSMENT METHODS

The student should eventually demonstrate:

  • Basic knowledge of biology, anatomy and physiology of neurosensorial systems.
  • Capacity of distinguishing and analysing the correlations among perceptual sensations, characteristics of the sensory signals, and biological structure.
  • Mastery of methods, techniques and instruments to experimentally characterize perceptual phemomenology.
  • Experience of possible application domains.

The oral exam is aimed at (1) verifying the acquisition of the concepts presented in the course, and (2) evaluating the ability of analysis and modeling on specific problems.

In general, in addition to the correctness and completeness of the answer, the evaluation criteria comprise: the relevance to the question, the clarity of the answer, and the ability to synthesise.
