The article “Skin Deep” written by Nina G. Jablonski and George Chaplin discusses the evolution of skin color. Right from the beginning of the article, Jablonski and Chaplin debunked the existing theory that darker skin color evolved to protect humans against skin cancer. As a matter of fact, evidence has shown that skin color in humans is the product of natural selection. “Skin Deep” also discusses topics like melanin, skin cancer, and how human migrations took an important role in the evolution of skin color.

The first thing that I learned about perception was earlier discovered by a psychologist by the name of Max Wertheimer. He discovered that our body clearly separates images into figures

seen and provide a way that afterwards the child can then understand and be able to communicate what they have seen effectively. These skills are all very crucial in helping children and young people to learn and manage how to listen and understand different concepts. They can then have a chance to develop their own opinions and ideas to then be able to participate in different decision making and problem solving in appropriate ways. Babies are nonverbal so to begin with they use sounds and facial expressions to communicate to adults expressing themselves and their needs (e.g. smiling, cooing and gurgling). Toddlers then start to have a small understanding and can use words and gestures to make connections to people and be able to develop their knowledge and understanding

Our study of the distinctively visual deepens our understanding of the world and those who inhabit it.

It is about reading faces and expressions. It is about making decisions from our “unconscious part of brain that is faster and often more correctly than the logical part of the brain can manage. In

and exercise. Whilst early on vision is best at 25cm they can gradually focus on objects further away. • Intellectual Development: Baby explores its environment by putting objects in its mouth. They become aware of different smells and can recognise familiar faces and voices. Baby can focus on moving objects and responds to brightly coloured bold images. Baby is egocentric. • Communication and Language Development: Baby will turn head towards sounds and recognises familiar voices – will stop crying when it hears them. Baby responds to smiles when not upset, pauses to listen and makes noises as well as crying to gain

Determining the most beneficial augmentative and alternative communication device is a critical component in AAC because it takes time and dedication to teach a client how to use the device as well as teach others around them how to understand. Hypothetically if a SLP were to provide wasted effort the results could have the potential to be devastating because in some circumstances all the client has is little time. Lucky enough for speech language pathologists there are models for assessment that provide guided intervention tactics. Assessment models can be described as feature matching, the participation model, and or the universal design for learning. Typically, feature matching is a quick and easy way to guide assessment because essentially

Are faces special? Critically evaluate the evidence that we have evolved a specialised neural network dedicated to processing faces. Brian Marron, 11461992, SF TSM.

The way a human eye and brain works together to produce visual data understandable to the

Distinctive facial features. A child may have a small head, flat face, and narrow eye openings, for instance. This gets more obvious by age 2 or 3 years.

Great writers create great characters. The novel, High Fidelity, focuses on the life of Rob, owner of a record store who his girlfriend just left him for another guy. Rob tells and describes the stories of his relationships and his breakups. He faces many struggles because of the decisions he made himself in the past. Hornby created Rob and Laura as believable characters and made Rob a victim of himself to describe the flaws in human beings.

Our brains can process perceptions in two ways: Bottom up and top down. In bottom up processing, there are 3 different ways that a person interprets or perceives what they see. Template matching uses prior knowledge of an object and creates a template using that prior knowledge. For example, the brain can use a template of the letter A in order to perceive an A. Template matching is very particular and uses every detail to create a template. However, prototype is a more generic type of matching. Prototype uses an idealized representation of an object or event. For example, to perceive a dog, the brain uses a generic idea of a dog (head, pointy ears, wet nose, big jowls). The third type of bottom up processing is called categorical perception.

Compare and contrast Marr and Nishihara’s and Biederman’s theories of object recognition. How well do they explain how we are able to recognize three dimensional objects despite changes in viewing angle?

At birth newborns eye muscles and nerves are still developing, so their vision is not great. At birth infants can see an estimated 20/240, but in six months’ time the babies’ vision tremendously increases and they are able to see at 20/40. As infant’s vision increases they begin to see color and eventually recognize shapes. By 8 weeks of age infants are able to see color and around 3 months they are able recognize that an objects shape stays the same, even if in a different setting. As infants develop they not only are able to distinguish colors and shapes but also are able to develop the ability to perceive objects that are occulted are in fact whole.
