Fetal Alcohol Syndrome (FAS) Essay Example | Topics and Well Written Essays - 750 words

Fetal Alcohol Syndrome (FAS) - Essay Example It was in 1977, Golden writes, that Americans viewed on national television for the first time a child suffering from fetal alcohol syndrome (FAS) (Golden, 1999, 269). What happened during that event when baby â€Å"Melissa† was introduced to the public was that the public had its first view and gained an understanding through the news segment during which Melissa was introduced by anchor David Brinkley of what FAS was and looked like (Golden, 269). The public learned that the –physical abnormalities of FAS are evidenced in children by conditions of mental retardation (MR), in combination with microcephaly, a condition of a small head; short palperable fissures, or very small eye slits; and a deficient mental ability (Golden, 269).While Melissa was not MR, she did demonstrate a deficient mental capacity, as described by Dr. Kenneth Lyons Jones, who conducted research studies through which he came to know baby Melissa (Golden, 269). The airing of the segment brought about an increased release of information to the American public on the dangers of alcohol and pregnancy (Golden, 269). More than two drinks a day during pregnancy, health officials cautioned, could bring about the very conditions from which Melissa suffered (Golden, 269). Even worse, the effects of alcohol consumption beyond two drinks a day could cause damage greater than what the viewing audiences were seeing as the physical impact of alcohol on baby Melissa (Golden, 269). Tresa M. Roebuck, Sarah N. Mattson, and Edward P. Riley (1999) of San Diego State University also collaborated in studying and writing a book on the effects of alcohol and alcoholism on the brain. â€Å"(Therefore)†¦the impact of prenatal alcohol exposure may be more subtle and far-reaching than once believed (Spear, Spear, Goodlett, 1999, 1),† the group concluded. Suggesting that perhaps less than two drinks per day is enough to adversely impact the developing

The Human-Computer Interface Assignment Example | Topics and Well Written Essays - 1000 words

The Human-Computer Interface - Assignment Example There are various types of the human memory, and human have limited capability to process the information. This information is stored in the different types of memory.†¢Ã‚  Short term or working memory: The short term memory is the capacity and store situated in the frontal lobes. Its function is to manipulate and update the representation, dividing and switching towards the tasks, and selection for the appropriate information. The retention time of the information in the short term memory is from seconds to minutes.†¢Ã‚  Sensory Memory: It corresponds to the perception of an item, and some of the information goes to sensory store, which is actually called as the short term memory. The retention time in sensory memory is in milliseconds to seconds. †¢Ã‚   Long term memory: Cognitive theory is also known as the theory of long term working memory in HCI. This is a long term memory, and requires practice as a prerequisite. Long term theory supposes that information is enc oded in the long term memory, and pace of encoding enlarges with the practice. Information in the long term memory, is encoded in a very organized system. Contrary to Short term memory, the long term memory is not inferred by the secondary task. (Oulasvirta and Saariluomas, 2004).A design team does not know the people behavior about the use of a product. A designer pays a conscious attention for the designing of the internal consistency. Consistency is more required in graphics and layout, dialogue forms and selection techniques.... ensory Memory: It corresponds to the perception of an item, and some of the information goes to sensory store, which is actually called as the short term memory.

This is a long term memory, and requires practice as a prerequisite. Long term theory supposes that information is encoded in the long term memory, and pace of encoding enlarges with the practice. Information in the long term memory, is encoded in a very organized system. Contrary to Short term memory, the long term memory is not inferred by the secondary task. (Oulasvirta and Saariluomas, 2004). 3. Describe the potential outcomes of not using consistency in the human-computer interface. A design team does not know the people behavior about the use of a product. A designer pays a conscious attention for the designing of the internal consistency. Consistency is more required in graphics and layout, dialogue forms and selection techniques. Each domain of the interface has a set of consistent dimensions. Inconsistency in color, size, style and shapes may create issues for the user. For example, Move forward is consistent with Move backward, but reverse, Go backward is not consistent. Inconsistency in HCI also fosters the level of confusion and frustration for the user as a user may access or generalize the other menu. In case of the inconsistent information, a user takes more time to answer the question on the screen. 4. Summarize and explain the steps of the user-centric design process. An engineer only operates the system to construct the design. System is developed on the need of the users. The users’ involvement for the design process is
