Answer:
Explanation:
1. Selective attention is the process of directing our awareness to relevant stimuli while ignoring the irrelevant. For example: when you pay attention to a professor in a class or doing your homework. A distraction defined by the Cambridge dictionary is “the state of being bored or something that prevents someone from giving their attention. For example, cellphones are a distraction when you are in school. Divided attention is when you perform two tasks at the same time. For example: when you watch a movie with subtitles or watch the tv while eating. Attentional capture is when an irrelevant item that is unique in some way affects the time to detect a target. For example: trying to find a seat at the cinema even though your friend is waving at you and you don’t notice. Scanning is reading a text quickly in order to find specific information. For example: A DMV employee needs to scan your information to get the details necessary.
2. The procedure consisted in turning down a volume of either one of the 4 sources that were available; or attenuate 3 in order to attend the fourth one. In the process they found that the participant could process the meaning of attend messages. Also, participants could still be able to identify the context of unattended messages; indicating they could identify both attended and unattended messages. The cocktail party effect is when you focus on a single speaker in any environment, even though the voice is surrounded by other noises. It demonstrated the capability of the human being to understand a speech if they really focus; listening to it and leaving all the distractions behind.
3. The broadbent’s model wanted to see how people were able to focus their attention (selective) by deliberately overloading them with stimuli. One of the ways was to send a message to one ear and a different message to the other. It is called the early selection model because it was one of the pioneers of creating a model who uses selective attention.
Answer:
The term that best describes this scenario is situational ethnicity.
Explanation:
A situational ethnicity is an ethnic identity that is particular to a social setting or context. It is an ethnic identity that is chosen for the moment based on the social setting or situation. Here one would choose to use one's ethnicity so as to use to one's advantage.
Answer: between 0.88 and 0.916
Explanation: parameters given are:
n = 1068
CI = 95 % = 1.96
p = 959
Let us Divide p by n.
959 \ 1068 = 0.898
Then,
0.898 -\+ 1.96 (√0.898 (1 - 0.898) \ 1068)
Find standard error
√0.898 (1 - 0.898) \ 1068 = 0.009
Also let us Find Margin of error.
(1.96)(0.009) = 0.018
Then calculate confidence interval.
0.898 -\+ 0.018 = 0.880 to 0.916
The 95% confidence, that the proportion of times NFL teams punt on a fourth down when they shouldn't be punting is between 0.880 and 0.916
Modern humans started spreading from Africa to Europe, Asia, and Australia some 100,000 years ago – a process that took about 70,000 years. We also know that at some point in the past 25,000 years, a group managed to reach America from Siberia at the end of the last ice age.
However, exactly when this occurred and which route these early pioneers took has long been debated. Now new research based on ancient DNA and plant remains from lake deposits, published in Nature, is finally helping us to answer these questions.Lake sediments can help shed light on the plant and animal life of this period because the successive layers of sediment allow us to step back in time to reveal a history of past environments. The researchers recovered sediment cores dating back to almost 13,000 years ago from an area of the corridor which is thought to be the last to become ice-free. Identification of the pollen grains and small fragments of plants in sediments are important in revealing vegetation development.
The sum would be -14k-14, if you distribute 5, then add the two groups together, that would be the answer you'd get.
