Part 2: Definitions. Describe, in just 1 or 2 sentences, how each of the following concepts is operationalized in the study indicated. (2 points each)

Grading Criteria:

  • 1 pt. for correctly identifying the concept
  • 1 pt. for using a procedural definition

11. Reversible versus Nonreversible Sentences

To determine if sentences are reversible or nonreversible I would present them to a group of participants and ask them to judge whether they still make sense when the agent and object are reversed (e.g., "The dog ate the bone." --> "The bone ate the dog."). Those for which a majority responded "yes" could then be classified as reversible while those for which a majority responded "no" could be classified as nonreversible.

12. Psychological Distance Between Two Words in a Sentence

To measure the psychological distance between two words in a sentence I would present the sentence to a group of participants along with several other sentences then ask them to make speeded recognition judgements (by pushing a YES or NO button as quickly as possible in response to words presented on a computer screen). I would measure recognition time for the second word in the sentence under two conditions, when it is predeeded by a the first word and when it is preceeded by a word from a different sentence, and use the difference between these two times as my measure of the psychological distance between the two words in the sentence.

13. Similarity of Two Sentences

To assess the similarity of two sentences I would include one of them in a list of to-be-remembered sentences, then ask a group of participants to choose between them in a two-alternative forced-choice recognition test. The similarity of the two sentences could then be defined as the percentage of participants who incorrectly choose the sentence that was not on the study list.

14. Psychological Distance Between Two Events in a Story

To measure the psychological distance between two events in a story I would present the story to a group of participants along with several other stories then ask them to make speeded true/false judgements by pushing a TRUE or FALSE button as quickly as possible in response to test sentences presented on a computer screen. I would measure the reaction time for the second of the two events under two conditions, when it is preceeded by a the first event and when it is preceeded by an event from another story, and use the difference between these two times as my measure of the psychological distance between the two events.

15. The Codability of Animals

I would present photographs of different animals (e.g., cows, humming birds, sloths, etc.) to participants on a computer monitor and ask them to generate a name for each as quickly as possible. The average naming latency (as measured by a computer) could be used to measure codability.

Part 3: Short Essay. Answer each of the following questions. Use no more than half a page for each answer and be sure to use examples were they are appropriate. (5 points each)

16. The English prepositions "in" and "on" are both translated into Spanish as "en". If the Sapir-Whorf hypothesis is correct, native speakers of English should, therefore, be more aware of and sensitive to the distinction captured by "in" and "on" than are native speakers of Spanish. Design an experiment to test this hypothesis. Be sure to describe the independent and dependent variables in your experiment. What pattern of results would you expect if the hypothesis is true? What pattern of results would you expect if it is false?

Grading Criteria:

  • 1 pt. for identification of I.V.
  • 1 pt. for identification of D.V.
  • 1 pt. for correct prediction if hypothesis is true
  • 1 pt. for correct prediction if hypothesis is false
  • 1 pt. for coherence of answer

Example Answer:

I would use an ABX discrimination task to test this hypothesis. The independent variable would be the native language of the participants (either English or Spanish). On each of several trials, they would be shown two pictures that differed along two dimensions, and one of those dimensions would involve the "in - on" distinctions. As an example, one picture might show a frog on a box and the other a turtle in a box.  Participants would then be shown a third picture that differed from each of the first two pictures along one of the dimensions (e.g., a frog in a box) and asked which of the first two pictures it was most like. The dependent variable would be the probability of matching on the basis of the spatial relation (in) rather than the other dimension (the frog). If the hypothesis is true, English speakers should match on the spatial relation more often than the Spanish speakers. If the hypothesis is false, the two language groups should not differ from one another.

17.Savin & Perchonock (1965) took advantage of the tradeoff between storage capacity and processing complexity in short-term memory in their experimental test of the derivational theory of complexity. How would you change their experiment to test the hypothesis that syntactic processing is facilitated by by semantic constraint? Be sure to describe the independent and dependent variables in your modified experiment, using operational definitions and/or examples where they are appropriate. What pattern of results would you expect if the hypothesis is true? What pattern of results would you expect if the hypothesis is false?

Grading Criteria:

  • 1 pt. for identification of I.V.
  • 1 pt. for identification of D.V.
  • 1 pt. for correct prediction if hypothesis is true
  • 1 pt for correct prediction if hypothesis is false
  • 1 pt. for coherence of the answer

Example Answer:

I would present participants with a list of unrelated sentences. Each sentence would be followed by a list of eight randomly selected words unrelated to the sentence. Participants would be required to repeat back each sentence verbatim, then repeat back as many of the eight words as they could remember. All of the sentences would be passive sentences taken from Slobin (1966) except for some filler sentences that wouldnot be scored. The dependent variable would be the number of randomly selected words recalled correctly (0 - 8). The independent variable would be the reversibility of the sentences (as in Slobin, 1966). Half of the passive sentences would be reversible, meaning that the subject and object could potentially reverse roles (as in, "The girl was chased by the boy."). The other half would be irreversible, meaning that the subject and object could not change roles (as in, "The bagel was eaten by the boy."). If the hypothesis is true, I would expect more words to be recalled when the sentence is irreversible. If the hypothesis is false, I would expect to find no difference between the reversible and irreversible sentences.
