Assessing Memory: Explicit and Implicit Memory Tests Mariana V. C. Coutinho, PhD Today’s Lecture Class Recap Assessing Long-term Memory Explicit Memory Tests Implicit Memory Tests Questions? 04/30/2024 2 Question What is the main difference between the explicit and implicit memory systems? 04/30/2024 3 Focus of Lecture Today The focus of our lecture today is on how psychologists measure LTM. You will learn about tests of explicit and implicit memory. 04/30/2024 4 Class Activity  We will start with a class activity.  You will complete three tests, and your task is to determine whether they are:  Explicit Memory Tests  Implicit Memory Tests 04/30/2024 5 First Test: Instructions  You will be presented with a list of words, your task is to study them since you will be tested on them later. 04/30/2024 6 First Test: Instructions  You will be presented with a list of words, your task is to study them since you will be tested on them later. Ready? 04/30/2024 7 First Test: Encoding Phase List of words  Moon  Desk  Mother  Elephant  Shelf  Speaker  Cable  Telephone  Clock  Medicine  Course 04/30/2024 8 Filler Trial Please answer the following question. 20*100 = ? 5*7 = ? 04/30/2024 9 First Test: Test Phase Write down as many words you can remember. 04/30/2024 10 First Test: Test Phase Write down as many words you can remember. Moon Desk Mother Elephant Shelf Speaker Cable Telephone Clock Medicine Course 04/30/2024 11 The test you performed is an example of a test of __________ A. Explicit Test B. Implicit Test 04/30/2024 12 The test you performed is an example of a test of __________ A. Explicit Test B. Implicit Test Why? 04/30/2024 13 The test you performed is an example of a test of __________ A. Explicit Test B. Implicit Test Why? Conscious retrieval 04/30/2024 14 Now let’s describe explicit memory tests in detail. 04/30/2024 15 Assessing Explicit Memory Two types of tests Recall Test Recognition Test 04/30/2024 16 Recall vs. Recognition Memory Test How do they differ? Recall Test Generate the information previously studied. Recognition Test Identify the information previously studied. 04/30/2024 17 Recall vs. Recognition Memory Test How do they differ? Recall Test Generate the information previously studied. For example: the test you just performed. 04/30/2024 18 Recall vs. Recognition Memory Test Recognition Test Identify the information previously studied. For example: multiple-choice question. 04/30/2024 19 Designing a Memory Test Most tests of Long-term Memory includes two phases: Encoding Phase Retrieval Phase 04/30/2024 20 Designing a Memory Test  Encoding Phase (Presented with a list of words) Retrieval Phase (Prompt to retrieve them) 04/30/2024 21 Encoding Phase The encoding phase is when stimuli (to be remembered) are presented to participants. 04/30/2024 22 Encoding Phase The encoding phase is when stimuli (to be remembered) are presented to participants. For example: list of words. 04/30/2024 23 Encoding Phase  For example: Study the following words carefully because you will be tested on them later.  Printer         Desk Computer Mouse Shelf Speaker Cable Telephone Clock 04/30/2024 24 Designing a Memory Test Most tests of Long-term Memory includes two phases: Encoding Phase Retrieval Phase 04/30/2024 25 Retrieval Phase The retrieval phase is when participants are asked to retrieve (through recall or recognition) the information previously studied. 04/30/2024 26 Retrieval Phase – Recall Test Write down as many word from the list as you can remember. 04/30/2024 27 Types of Recall Test Free Recall Cue Recall 04/30/2024 28 Types of Recall Test Free Recall No hint provided Cue Recall A cue is present 04/30/2024 29 Free Recall Encoding Phase dog chocolate basket … 04/30/2024 30 Free Recall Test Phase Write down all words you were presented with earlier 04/30/2024 31 Cue Recall Encoding Phase dog-cat chocolate-jelly basket-pen … 04/30/2024 32 Cue Recall Test Phase What word is missing in the pair? dog-? chocolate-? basket-? 04/30/2024 33 Class Activity Now we are going to complete another test. Your task is to determine whether it is a Implicit Memory Test Explicit Memory Test 04/30/2024 34 Instructions For the experiment today you will complete two task. The first one, please indicate if the following words are pleasant or unpleasant. 04/30/2024 35 Door 04/30/2024 36 Test Phase Please complete the word stem with the first word that you can think of: Do______ Or______ Lo_______ ____art 04/30/2024 37 Question What type of memory test is this? Implicit Memory Test Explicit Memory Test 04/30/2024 38 Question What type of memory test is this? Implicit Memory Test Explicit Memory Test Why? 04/30/2024 39 Assessing Implicit Memory Psychologists use the following tests to induce priming and assess implicit memory: Word-fragment Word - stem completion 04/30/2024 40 Let’s describe the priming test in more detail … 04/30/2024 41 Word-fragment/Word - stem completion Training Phase (participants are exposed to words but not told that their memory will be tested later on)  They are asked a question about the words to ensure they paid attention to them.  For example: indicate whether they are pleasant words. 04/30/2024 42 Word Fragment Completion Test Phase: please complete the fragments with the first word that comes to mind A_p_e O_r_n_ _ B_r_ 04/30/2024 43 Word Stem Completion Test Phase: please complete the word stem with the first word that you can think of: Do_______ OR_____ 04/30/2024 44 Participants complete the word stem or fragments using words that they seen before. And they are not aware of doing so. 04/30/2024 45 Thank you! 04/30/2024 46
