The Effects Of Cognitive And Perceptual Load - 1543 Words

The effect of cognitive and perceptual load, cued attentional focus and stimulus rarity on attentional capture by abrupt-onset stimuli. ABSTRACT: Abrupt-onset stimuli have been observed to exhibit significant attentional capture effects, however the automaticity of this process has been questioned in recent literature (Yantis Jonides, 1990; Neo Chua, 2006). The current study examined the effect of pre-focused attention and stimulus frequency on attentional capture by abrupt-onset stimuli, in order to further explore the automaticity of this process. It was observed that abrupt-onset stimuli are effective in capturing attention, but the strength of this effect is greatly determined by other variables, including attentional focus and stimulus rarity; and in particular, cognitive and perceptual load (Minamoto et al., 2015; Lavie Tsal, 1994). It was concluded that attentional capture by abrupt-onset stimuli is not an automatic process as it fails to meet the load-insensitivity and intentionality criteria (Yantis Jonides, 1990). These findings lay a foundation for further attentional research, an important factor of educational psychology. The effect of cognitive and perceptual load, cued attentional focus and stimulus rarity on attentional capture by abrupt-onset stimuli. Attention is a cognitive phenomenon that describes an individual’s ability to focus their awareness on salient external stimuli (Rensink et al., 1997). Automatic attentional capture, i.e.Show MoreRelatedLiterature Review : Cognitive Load1018 Words   |  5 PagesMarch 2016 Literature Review Cognitive load is the degree of effort that an action requires for completion, associated with working memory and characterised by elements such as reaction time and accuracy, especially within the context of conflicting stimulus (Lavie, 2010). A facet of the load theory of attention, closely intertwined with concepts such as perceptual load, or how the degree of effort it takes to maintain focus on a specific stimulus, cognitive load can be seen to focus more heavilyRead MoreComparing Attentional Capture By Rare And Constant, Novel, Sudden Onset Stimuli1548 Words   |  7 Pagesaffect attentional processes may be established. Based upon the experimental findings, it is proposed that when a sudden onset stimulus is both rare and novel, the attentional capture processes when perceiving these stimuli are influenced by perceptual load and modes of attention. Implications of these findings are discussed further in the paper.

Perception and attention are two independent mechanisms relevant to one another. Attention is the state of focused awareness on a division of available perceptual information. This paper will explain the concept of perception, break down the perceptual organizational process, define the concept of attention, analyze the nature of the attention process and explain the relationship between perception and attention. Define the concept of perception Read MoreThe Automation And Its Effects On The Environment784 Words   |  4 Pagesproblem to fix. The most common being that humans are typically drawn to situations that bias toward automation is natural, such as; choosing a path requiring less effort, natural trust in a system that has not failed previously, and the psychological effect of delegating tasks in a shared responsibility environment (Parasuraman Manzey, 2010). Compounding on the issue is that bias does not appear to be resolved by experience of the operator as it influences the natural human factors for which automationRead MoreAnxiety and Attention: The Gap in Research Essay3207 Words   |  13 PagesToday, cognitive psychologists know an extensive amount of information on our attention – our ability to divide our attention, our ability to selectively choose what we want to attend to and so on. It is agreed on that our cognitive load and resources are two of the influencing f actors when studying how attention works. In a normal-functioning mind, studying these two aspects may be enough to understand how our attention operates, but cognitive psychologists must delve much deeper than this whileRead MorePhysical Development And Child Development929 Words   |  4 Pageschild starts to develop, because it is the more physical and bigger movements for a child and baby to make. Physical development itself is ‘comprising changes in body size (growth) and proportions, the order and acquisition of motor skills, and perceptual and motor capacities’ (Doherty and Hughes, 2009, p.8). This is why parents see physical development first, it is not just the movements that the children achieve it is also how fast they grow, ‘from birth to age 6 months, a baby may grow 1/2 toRead Moreaging Essay6944 Words   |  28 PagesCOGNITIVE AND PERCEPTUAL FACTORS IN AGING AND DRIVING PERFORMANCE* Edward J.

Intelligence, for psychometric tests, refers to the innate overall cognitive ability. There are four versions of the Wechsler scales: the Wechsler Intelligence Scale for Children 4th edition (WISC-IV; Wechsler, 2003) for children aged 6-16, the Wechsler Preschool and Primary Scale of Intelligence Revised for children aged 4 - 6 1/2Read MoreLink Between Spatial Attention And Social Anxiety1480 Words   |  6 Pagesmechanisms which underlie such selective processing in models of anxiety(Clarke et al 2013). There are several different models of anxiety processing, however in this paper only the cognitive model of anxiety will be used. This model will be used because it uses both automatic and controlled processes that disrupts the cognitive economy to induces a state of anxiety. The model also gives an insight on the response on the physiological and behavioral changes that take place while undergoing the processRead MoreHow Does Distraction Affect Information Processing?1574 Words   |  7 Pagestheir attention. Digging even deeper into the connection between distractions and attention, Lavie (2010) utilizes cognitive load theory to demonstrate that under conditions of high perceptual load, such as in the task of learning or repeating new information, distractions are especially debilitating to information processing. On the other hand, when the task has low perceptual load such that it does not use much working memory, information processing is not as affected. Theoretically, it is thus
