Dobkins and Bosworth (2001) investigated divided attention effects on motion processing by employing a “set-size effects” paradigm (see Fig. Attenuation theory is a model of selective attention proposed by Anne Treisman, and can be seen as a revision of Donald Broadbent's filter model.Treisman proposed attenuation theory as a means to explain how unattended stimuli sometimes came to be processed in a more rigorous manner than what Broadbent's filter model could account for. This is especially important for survival in dangerous situations. As such it is a gateway to the rest of cognition. But the process of how we choose stimuli, and what happens to the rest, has been up for debate throughout the scientific community over the years. This information handout explains selective attention and its role in cognitive behavioral therapy (CBT). The advantage of selective attention is that it allows us to focus on important elements of our environment while blocking out things that could be distracting. Because it is impossible to give attention to every stimulus in our environment, we use selective attention to select what stimuli are important as events occur. Selective attention is our coping mechanism to process the information around us. However, divided attention is the ability to divide ones attention between two or more tasks.  : 5–7 The contrast of the two theories placed a new emphasis on the separation of visual attention tasks alone and those mediated by supplementary cognitive processes. Of the many cognitive processes associated with the human mind (decision-making, memory, emotion, etc), attention is considered the most concrete because it is tied so closely to perception. A type of attention which involves focusing on a specific aspect of a scene while ignoring other aspects. This experiment reveals two things: that we are missing a lot of what goes on around us, and that we have no idea that we are missing so much. It was as though the gorilla was invisible. Selective attention intervenes after this stage to select information that will be entered into visual short-term memory." It is described in most introductory textbooks and is featured in more than a dozen science museums. Attention is a limited resource, so selective attention allows us to tune out unimportant details and focus on what really matters. However, focusing too much on one thing could be a disadvantage if other things in the environment require more urgent focus. Selective attention is a cognitive process in which a person attends to one or a few sensory inputs while ignoring the other ones. 81.1A ). Psychologists have understood without the need for experimentation that we can only pay attention to a limited set of stimuli at one time. To our surprise, it has become one of the best-known experiments in psychology. The "cocktail party phenomenon" is a process that allows us … Selective attention is the process of focusing on a particular object in the environment for a certain period of time. In contrast to selective spatial attention studies, divided attention studies address how dividing attention across multiple stimuli in a display affects stimulus processing. Selective attention is the process of focusing on a particular object in the environment for a certain period of time. Therefore, it is worthy to explore its characteristics and functions, ways to control it and investigation methods. Attention is one of the most intensely studied topics within psychology and cognitive neuroscience. Selective attention can be conscious (as when one chooses to attend to an interesting object, like a tv, instead of a less interesting one, like a coffee table) or unconscious (as in a scene of a green field with a single red tulip - the tulip will receive attention initially). Selective attention is purposely focusing your conscious awareness onto a specific stimulus. Selective Attention I've always been somewhat bothered by this term because it seems somewhat redundant to me...see what you think. Selective attention can be conceptualized as a maintaning process (mechanism) within CBT. Biases in perception can lead to biases in information processing negative emotion.
