What is Perception? what is the difference of Perception and Sensation? I hope that this Presentation will help... Credits: Professor Charmaine Maglangit
This PPT contains Perception from Unit 3 Cognitive Process of the subject Psychology for F.Y.B.Sc. Nursing.
Perception is a fundamental cognitive process that involves interpreting and making sense of sensory information received from the environment. It's how we organize and interpret what we see, hear, feel, taste, and smell, allowing us to create a meaningful understanding of the world around us. Perception plays a crucial role in shaping our thoughts, behaviors, and interactions with the external world.
Explain the concepts perception and sensation in terms of the functioning of the sense organs
- Discuss organisation under: form perception, depth perception, perceptual consistency, perception of movement
- Describe the concept Illusion
- Describe extra sensory perception (ESP)
- Outline 3 main types of ESP

Chapter 6: Perception
Selective Attention
At any moment we are conscious of a very limited amount of all that we are capable of experiencing. One example of this selective attention is the cocktail party effect—attending to only one voice among many. Another example is inattentional blindness, which refers to our blocking of a brief visual interruption when focusing on other sights.
Perceptual Illusions
Visual and auditory illusions were fascinating scientists even as psychology emerged. Explaining illusions required an understanding of how we transform sensations into meaningful perceptions, so the study of perception became one of psychology’s first concerns. Conflict between visual and other sensory information is usually resolved with the mind’s accepting the visual data, a tendency known as visual capture.
Perceptual Organization
From a top-down perspective, we see how we transform sensory information into meaningful perceptions when we are aided by knowledge and expectations.
The early Gestalt psychologists were impressed with the seemingly innate way we organize fragmentary sensory data into whole perceptions. Our minds structure the information that comes to us in several demonstrable ways:
Form Perception
To recognize an object, we must first perceive it (see it as a figure) as distinct from its surroundings (the ground). We must also organize the figure into a meaningful form. Several Gestalt principles—proximity, similarity, continuity, connectedness, and closure—describe this process.
Depth Perception
Research on the visual cliff revealed that many species perceive the world in three dimensions at, or very soon after, birth. We transform two-dimensional retinal images into three-dimensional perceptions by using binocular cues, such as retinal disparity, and monocular cues, such as the relative sizes of objects.
Motion Perception
Our brain computes motion as objects move across or toward the retina. Large objects appear to move more slowly than smaller objects. A quick succession of images, as in a motion picture or on a lighted sign, can also create an illusion of movement.
Perceptual Constancy
Having perceived an object as a coherent figure and having located it in space, how then do we recognize it—despite the varying images that it may cast on our retinas? Size, shape, and lightness constancies describe how objects appear to have unchanging characteristics regardless of their distance, shape, or motion. These constancies explain several of the well-known visual illusions. For example, familiarity with the size-distance relationships in a carpentered world of rectangular shapes makes people more susceptible to the Müller-Lyer illusion.
Perceptual Interpretation
The most direct tests of the nature-nurture issue come from experiments that modify human perceptions.
Sensory Deprivation and Restored Vision
For many species, infancy is a critical period during which experience must activate the brain’s innate visual mechanisms. If cataract removal restores eyesight to adults who were blind from birth, they remain unable to perceive the world normally. Generally, they can distinguish figure from ground and can perceive colors, but they are unable to recognize shapes and forms. In controlled experiments, animals have been reared with severely restricted visual input. When their visual exposure is returned to normal, they, too, suffer enduring visual handicaps.
Perceptual Adaptation
Human vision is remarkably adaptable. Given glasses that shift the world slightly to the left or right, or even turn it upside down, people manage to adapt their movements and, with practice, to move about with ease.
Perceptual Set
Clear evidence that perception is influenced by our experience—our learned assumptions and beliefs—as well as by sensory input comes from the many demonstrations of perceptual set and context effects. The schemas we have learned help us to interpret otherwise ambiguous stimu

Perception in psychology can be defined as the sensory experience of the world, which includes how an individual recognizes and interpreter sensory information. This also includes how one responds to those stimuli. Perception includes these senses: vision, touch, sound, smell, taste, and proprioception. These are all senses one takes in to understand the surroundings and respond to its demands. In general, there are a few steps in the formation of perception. First, there is an external stimulus for the sensory organs to detect, for example, the barking of a dog. In this example, the ears will be responsible to detect the stimulus. If the individual pays attention to the bark, the attended stimulus will be transcribed from auditory information into neurological signals and transducer to the brain. Inside the brain, the individual will recognize it as a dog's barking. Then according to one's knowledge and experience with a dog barking, they will carry out a corresponding response to the situation. If the individual is scared of dogs, they may choose to quickly leave or stay further away from the dog. One example can be a mother preparing a meal for a baby. The mother may try the food before feeding. If the food is too hot, the mother will wait until it is cooled in order to protect the baby from a burn. In this case, tactile perception is used Perception is the way individuals recognize and interpret the environment. It is necessary for survival. For example, when one is walking on the street, an accurate and efficient perception of an out-of-control car that is speeding toward them will help them escape from possible injuries from getting hit. In this example, it involves the ability to see and hear the car and maybe people around shouting for the individual's attention. Then it requires the individual to put together all the perceptions of the car and derive meaning from them, ie. they should escape and stay away from the car.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
