action at a time, and humans see their world in objects. Another purpose of attention is so that actions can be directed and controlled (Allport, 1987 cited in Naish 2010). It is important to research this in order to optimise health and safety and performance in occupational fields and make further discoveries in clinical neuropsychology. Some debates rage around how we attend to objects through our auditory and visual processes. Early selection theorists argue that all extraneous information
deficit hypothesis is the leading theory to arise from research, which leads Shaywitz (1996) to suggest a child which holds an insufficiency within discourse at the phonological level, leads to impairment in their capability to section the written word into its fundamental phonological elements. This blocks access to more advanced linguistic processes and deters deriving meaning from text, with the main focus of this hypothesis focusing on oral language instead of visual perception. Several studies have
activate if the surrounding was dark and center was light-on; the reverse is true for the off-center RF. There are two complementary theories of color vision: One of them is the dominant and popular trichromatic theory, which argues that three types of cones (L, M, S) are sufficient to code the color vision. However, Hering raised a different theory--- color opponent theory. He argued that there were four elemental colors (R,Y, G, and B) not three. He also noted the pairing of R & G, and of B & Y. Three
of speech perception which combines auditory and visual inputs to form a cohesive and comprehensive speech percept (Nath and Beauchamp, 2012). In their 1976 article ‘Hearing Lips and Seeing Voices’, Harry McGurk and John MacDonald described a perceptual phenomenon they referred to as ‘the McGurk effect’ (McGurk and MacDonald, 1976). The McGurk effect is an audiovisual illusion that is
Divided attention refers to the ability to divide ones attention between two or more tasks. The focused attention models explain how all our inputs are focused on one task at any one time, however it is clear from looking at everyday life that we are able to divide our attention, successfully being able to complete more than one task at the same time. There are two main explanations of divided attention, one is the modular theories and the one I will be focusing on; the capacity model by Kanheman
early vs late selection models of attention. How well do they explain how we selectively attend to information? Attention was described by William James (1890, cited in Eysenck & Keane, 2000, p130) as “the taking possession of the mind, in clear and vivid form , of one out of what seem several simultaneously possible objects or trains of thought. Focalisation, concentration of consciousness are of its essence.” This definition emphasises how attention is thought of as a selective process
Both attention and perception are concepts that relate to the cognitive development of human beings. Both concepts contribute to our ability to control and direct the processing of stimuli, whether it is physical, visual, auditory or retrieved from stored memory. Perception is the ability to make sense of our surroundings, whereas attention is the ability to concentrate on any perceived stimuli. A link between perception and attention comes from an individual’s ability to choose which stimuli to
An auditory brainstem response is an electrical potential generated from the changes in neural activity when an acoustic stimulus is presented into the ear. Stimuli in the form of clicks, tonebursts or chirps are transmitted through a transducer and measured using surface electrodes positioned on the scalp. The elicited waveform response consists of 7 waves that occur within a period of 10ms after the presented stimuli. Each waveform peak is labeled from I-VII where each wave corresponds to a neural

Multiple Intelligence theory maintains that there are at least seven learning styles (“intelligences”): interpersonal, intra-personal, body/kinesthetic, visual/spatial, mathematical/logical, verbal/linguistic and musical/rhythmic (Lazear, D.1991). For the purposes of this paper I will simplify the seven categories into three main categories in which people
