The And Late 's Selection Theory Controversy

The Stroop effect is demonstrated by the reaction time to determine a color when the color is printed in a different color’s name. Participants respond slower or make more errors when the meaning of the word is incongruent with the color of the word. Despite knowing the meaning of the word, participants showed incapability of ignoring the stimulus attribute. This reflects a clear instance of semantic interference and an unfathomed failure of selective attention (Stroop, 1935).

We think important objects and events in our world will automatically grab our attention, but they often don’t, particularly when our attention is focused on something else. Cocktail Party Effect describes the ability to focus your hearing on one specific thing even though noise is all around you. It is named such because this occurs when you are at a party- you can focus on the conversation you are having with the person close to you and can ignore all the other noise and conversation going on around you. Your brain helps you selectively focus on the person you are talking too and 'mutes' the other conversation, music, and general noise around you. Whereas, the failure to notice unexpected objects or events when attention is focused elsewhere is now known as inattentional blindness. The interface between attention and consciousness are examples of the Cocktail party and Inattentional blindness.

Attention is thought to be selective-focused on one subject at a time. Traditionally, it has been assumed that automatic processing is involuntary, it does not require attention, and is relatively fast; whereas, controlled processing is voluntary, does require attention, and is relatively slow. We can conclude from this that the more we repeat a certain material or tasks the more it becomes automatic and effortless to us.

One’s individuality and freedom are questioned when it does not conform to society’s ideals. This is often demonstrated in real life, as well as in popular literary pieces.

Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical

The results show that although the primacy effect was apparent in the results of both tests, the recency effect was not observed in Test 2(as predicted) and strangely not observable in Test 1 either. The reason for this may be the presence of uncontrolled external stimuli caused between the participants listening time and

Selection. Selection is defined in the book as the following “The process of attending to a stimulus.” (Floyd, pg. 109) I have watched this video over and over before writing this paper, but the first time I watched it nothing really stood out to me besides

In order to come to a decision concerning these two questions, several authors, among them Peter Carruthers, Daniel Dennett, Colin McGinn, Nicholas Humphrey and Robert VanGulick, refer to an empirical phenomenon called "blindsight". (2)

In topic 1, the introduction to human uniqueness and social coercion theory, we are introduced to some of the common misinterpretation behind Charles’ Darwin’s theory of evolution, specifically in regards to natural selection and survival of the fittest. One of the biggest contributors to this issue is the lack of exposure to the general public on the overall theory behind these two processes. Instead of a full detailed explanation about natural selection and survival of the fittest, we are just told that it is slow and that to be fit means a level of superiority among competition, respectively. Topic 1 revealed that this is not true, as well as stating that natural selection is about individual risk, benefit and cost is of the utmost importance(Bingham). Based on this newly found insight from the course, how does individual risk, benefit, and cost play such an important role in natural selection even though selection is seen in a population and not a

In the paper, The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information, George A. Miller points out the correlations between neural processing to recognize previously shown information and the amount of information that can actually be remembered. He presents several experiments done with unidimensional stimuli, where there is only one stimuli, and multidimensional stimuli, where there are more than one. In the first experiments talked about, only one sensory process was tested. For example, Pollack’s experiment tested the auditory sense and the ability to differentiate between pitches. Other experiments were recognized that included the other senses, taste and sight, and all the responses varied around the number six. After around six correct responses,

Early studies have widely researched attention with selective processing (Driver, 2001). Broadbent (1958) filter theory of attention states that certain information does not require focal attention. It is based on certain stimulus attributes such as colour and shape (Friedenberg, 2012). A previous study carried out by Treisman and Schmidt (1982) proposes that when attention is diverted from a display of several figures, the participants incorrectly combine the features of colour and shape therefore increases the illusory conjunctions portrayed by the participants (Tsal, 1989). Another study by Shaw (1978) found that reaction time of participant to identify targets varied with the probability that a target would appear in a particular display location. These results indicate that different amounts of attention towards the targets are distributed to different positions in the visual field. However, Houck and Hoffman (1986) found that the feature integration of colour and orientation can sometimes be accomplished without attention (James et al.,

The article by Avital-Cohen and Tsal (2016) discussed the flanker task experiment, which asserted that distractor interference happens unconsciously as a result of focused attention toward the target. The results from the original flanker task indicated that participants had slower responses for incongruent trials, since the distractors are inconsistent with the target and would require a different response (Avital-Cohen & Tsal, 2016). However, Avital-Cohen and Tsal (2016) questioned the findings from the flanker task experiment. They decided to challenge the idea that only the target stimuli receives top-down processing, and not the distractors (Avital-Cohen & Tsal, 2016). The first experiment aimed to test whether the distractor interference is purely bottom-up processing as claimed in the flanker task. The experiment manipulated participants’ expectations of the target using the context effect - a type of top-down processing - by changing the distractors to be either letters or digits (Psych 240 lecture, 9/21/16). Then, the researchers conducted a second experiment and eliminated the ambiguity of distractors. They wanted to test whether the result from experiment 1 was caused by an overall bias or the ambiguous distractors. In experiment 2, the researchers predicted that they would obtain similar results to the first experiment only if the results were due to an overall bias effect (Avital-Cohen & Tsal, 2016). This study allows us to deepen our understanding of available

Late selection models provide a possible explanation for results obtained in some dichotic listening experiments where processing of unattended stimuli did seem to take place. For example, Corteen and Wood (1972, as cited in Naish, 2010), paired electric shocks with certain words, so that a conditioned galvanic skin response (GSR) took place. Later, when these words were again presented to the unattended ear , (without electric shocks), the GSR still occurred for these words as well as other words from the same category, indicating that processing for meaning had indeed taken place. Late section theories could also be used to explain the cocktail party effect (Naish , 2010) i.e. if someone is attending to one conversation at a party and their name is mentioned in another conversation in the room, they are able to hear their name and switch their

The study written about here’s aim was to look at the development of selective attention by using the cross-model Stroop test. The study used fifteen 4-5 year olds, fifteen 6-7 year olds, fifteen 9-11 and thirty undergraduates to participate in the study. The participants were tested individually in a lab and were told they would play a computer game, the aim of the game was to name to colour that appeared of the computer screen however they were wearing head phones and sometimes they would hear a word that could confuse them. The participants were given multiple trial, the first consisting of 18 rounds that occurred in silent conditions, giving the participants a chance to practice and

Research carried out on attention has mainly been associated with the selective processing of incoming sensory information. It proposes, to some degree, our awareness of the world depends on what we choose to focus on and not simply the stimulation received by our senses. Attention is often linked to a filter that screens out most potential stimuli whilst allowing a select few to pass through into our conscious awareness, however, a great deal of debate has been devoted to where the filter is situated in the information processing chain (Martindale, 1991). Psychologists have made extensive contributions to this subject matter in the past century. Notable examples include Donald Broadbent's filter theory of attention (1958), which set the
