Sensory, Attentional And Perceptual Processes

This section explores the key processes of sensation, attention, and perception, detailing how humans interact with their environment through sensory modalities and the cognitive functions that influence perception.

Introduction

This section introduces sensory, attentional, and perceptual processes, emphasizing their interrelation in acquiring knowledge about the world.

Knowing The World

This section explores the processes through which we gain knowledge of our environment, emphasizing the roles of sensation, attention, and perception.

Nature And Varieties Of Stimulus

This section discusses the variety of stimuli present in our environment and how our sensory systems are specialized to process these stimuli, highlighting the nature of sensation and its role in perceptual processes.

Sense Modalities

This section covers the various sense modalities, the functionalities and limitations of sense organs, the processes of sensation and perception, and factors influencing these processes.

Functional Limitations Of Sense Organs

This section discusses the functional limitations of human sense organs, emphasizing how stimuli must exceed specific thresholds to be perceived.

Attentional Processes

This section explores the concept of attention, its types including selective, divided, and sustained attention, and the factors that influence them.

Selective Attention

This section explores the concept of selective attention, its types, influences, and the processes underlying how we focus on specific stimuli while ignoring others.

Sustained Attention

Sustained attention refers to the ability to maintain focus on a specific task or stimulus over an extended period.

Perceptual Processes

This section explores the processes of perception, explaining how sensory information is interpreted and various factors that influence perception.

Processing Approaches In Perception

This section explores the dual nature of perceptual processing through bottom-up and top-down approaches, and how both contribute to our understanding of sensory information.

The Perceiver

The section discusses how humans interpret sensory information, emphasizing the active role of the perceiver shaped by motivations, expectations, and cultural backgrounds.

Principles Of Perceptual Organisation

This section explores how we organize visual stimuli into meaningful wholes, detailing key principles outlined by Gestalt psychologists.

Perception Of Space, Depth, And Distance

This section explores how we perceive space, depth, and distance using various monocular and binocular cues.

Monocular Cues And Binocular Cues

Monocular and binocular cues are essential for depth perception, providing different ways for the brain to interpret three-dimensional space from two-dimensional images.

Perceptual Constancies

Perceptual constancies allow us to maintain a stable perception of objects despite changes in sensory input.

Illusions

Illusions are misperceptions caused by the brain's interpretation of sensory information, often resulting in a disconnect between physical stimuli and perceived experience.

Socio-Cultural Influences On Perception

This section explores how socio-cultural factors shape and influence human perception.

Key Terms

This section outlines the essential terms related to sensory, attentional, and perceptual processes, detailing their definitions and significance.

Summary

This section summarizes the key concepts of sensory, attentional, and perceptual processes, emphasizing their interrelated nature and relevance in understanding our experiences of the world.
