Frage 21 von 42

1

Identify the dependent & independent variable.
Compared to children, adults are bad at learning language. This is counterintuitive; adults outperform children on most measure of cognition, especially those that involve effort (which continue to mature into early adulthood). The present study asks whether these mature effortful abilities interfere with language learning in adults & further, whether interference occurs equally for aspects of language that adults are good (word-segmentation) versus bad (Grammar) at learning. Learners were exposed to an artificial language comprised of statistically defined words that belong to phonologically defined categories (grammar). Exposure occurred under passive or effortful conditions. Passive learners were told to listen while effortful learners were instructed to try to 1) learn the words, 2) learn the categories, or 3) learn the category order. Effortful learners showed an advantage for learning words while passive learners showed an advantage for learning the categories. Effort can therefore hurt the learning of categories.
Q: A dependent variable in this study is:

Wähle eine der folgenden:

effort expended
how well the words are learned
whether the participants are instructed to learn words or categories
the age of the participants in the experiment

Erklärung

Frage 22 von 42

1

Consider the following paragraph from the Method section of the paper on page 3.
After exposure, participants completed 2 forced choice tests: (1) a word-level test in which they were asked which of two words was more likely to belong in the language they just listened to, and (2) a sentence-level test in which they were asked which sentence was more likely to belong in the test were randomized separately for each subject. In these 2 tests, there were 3 types of interest: word segmentation, order & category structure. All word segmentation items occurred in the first, word-level, test and all of the order & category structure occurred in the second, sentence-level test.
Q: Which of the following best describes the design of this study?

Wähle eine der folgenden:

independent groups
repeated-measures
longitudinal
pretest-posttest

Consider the following paragraph from the Method section of the paper on page 3.
After exposure, participants completed 2 forced choice tests: (1) a word-level test in which they were asked which of two words was more likely to belong in the language they just listened to, and (2) a sentence-level test in which they were asked which sentence was more likely to belong in the test were randomized separately for each subject. In these 2 tests, there were 3 types of interest: word segmentation, order & category structure. All word segmentation items occurred in the first, word-level, test and all of the order & category structure occurred in the second, sentence-level test.
Q: If the word-level test was always carried out first, this could potentially lead to:

You are studying an intervention that affects the whole community, so a control group is impractical

I ask the 10 students with the lowest grade on Midterm 1 to attend a compulsory review session before Midterm 2. Their scores on Midterm 2 are on average better than Midterm 1. Conclusion: My review session was effective.
I ask my students if they have any questions about the exam during a review session. None of them says anything in response to my question. Conclusion: None of the students have any questions.
