Assessment test to assess a person's ability to identify various odors. Participants use scratch 'n' sniff cards and after scratching them one at a time, are asked to identify which of four pictures on the computer screen matches the odor they have just smelled. Participants ages 10-85 are administered nine odor cards, while those ages 3-9 are administered five odor cards. Child participants (ages 3 -9 years) are first asked to identify the eight pictures that are used as answer choices, to ensure they can complete the task. Having identified the pictures, they are asked if they have tasted or smelled the objects or foods depicted. This test takes approximately 4 to 5 minutes to administer and is recommended for ages 3-85.

Assessment test to measure the memory of patients using their ability to sort objects. It requires immediate recall and sequencing of different visually and orally presented stimuli. Pictures of different foods and animals are displayed with accompanying audio recording and written text (e.g., elephant), and the participant is asked to say the items back in size order from smallest to largest, first within a single dimension (either animals or foods, called 1-List) and then on 2 dimensions (foods, then animals, called 2-List). The score is equal to the number of items recalled and sequenced correctly, and the test takes approximately 7 minutes to administer. This test is recommended for ages 7-85, but is available for use as young as age 3, if requested.

Data set that looked at religion, self-rated health, depression, and psychological well-being in a sample of older Blacks and older Whites (aged 65 and over) within the United States. Questions were asked regarding religious status, activities, and beliefs among those who currently practice the Christian faith, those who used to be Christian but are not now, and those who have never been associated with any religion during their lifetimes. Demographic variables include age, race, sex, education, and income. Wave II was collected in 2004 and reinterviewed 1,024 respondents. There were 75 respondents who refused to participate, 112 who could not be located, 70 that were too ill for participation, 11 who had moved to nursing homes and 208 were deceased. * Dates of Study: 2001- 2004 * Study Features: Longitudinal, Minority Oversample * Sample Size: 1,500

A supplemental instrument that is a measure of speed of processing. The participant is presented with a set of nine symbols on the computer screen, each associated with a number 1-9, and is then presented with a series of symbols without numbers and is asked to orally say each number that should go with that symbol, without skipping any. The score is equal to the number of symbols correctly identified orally within two minutes. Recommended for ages 8-85 as a supplement to the Pattern Comparison Processing Speed Test or as a potential alternative in cases where a participant's motoric limitations would preclude administering the Pattern Comparison Processing Speed Test. Takes approximately 3 minutes to administer.

Assessment test that measures the ability of patients to identify words and letters. The participant is asked to read and pronounce letters and words as accurately as possible. The test administrator scores them as right or wrong. For the youngest children, the initial items require them to identify letters (as opposed to symbols) and to identify a specific letter in an array of 4 symbols. The test is given in a computerized adaptive format and requires approximately 3 minutes. This test is recommended for ages 7-85, but is available for use as young as age 3, if requested. Separate but parallel reading tests have been developed in English and in Spanish.

Supplemental instrument that is a measure of immediate recall in which the participant is presented with a list of 15 unrelated words via audio recording and is asked to recall as many as he/she can. This process is repeated twice more, and the score is equal to the total number of words recalled across all three trials. This instrument is recommended for ages 8-85 as a supplement to the Picture Sequence Memory Test or as a potential alternative in cases where a participant's visual limitations would preclude administering the Picture Sequence Memory Test. The test takes approximately 3 minutes to administer. (The NIH Toolbox version of this test differs from some other available versions in that there are three rather than five learning trials and there is neither a delayed recall trial nor an interference trial.)

A measure for the assessment of episodic memory that involves recalling increasingly lengthy series of illustrated objects and activities that are presented in a particular order on the computer screen. The participants are asked to recall the sequence of pictures that is demonstrated over two learning trials; sequence length varies from 6-18 pictures, depending on age. Participants are given credit for each adjacent pair of pictures (i.e., if pictures in locations 7 and 8 and placed in that order and adjacent to each other anywhere such as slots 1 and 2 one point is awarded) they correctly place, up to the maximum value for the sequence, which is one less than the sequence length (if there are 18 pictures in the sequence, the maximum score is 17, because that is the number of adjacent pairs of pictures that exist). The test takes approximately 7 minutes to administer. This test is recommended for ages 3-85.

Assessment test that measures both a participant''s attention and inhibitory control. The test requires the participant to focus on a given stimulus while inhibiting attention to stimuli (fish for ages 3-7 or arrows for ages 8-85) flanking it. Sometimes the middle stimulus is pointing in the same direction as the flankers (congruent) and sometimes in the opposite direction (incongruent). Scoring is based on a combination of accuracy and reaction time, and the test takes approximately 3 minutes to administer. This test is recommended for ages 3-85.

Assessment test that measures the cognitive flexibility of patients. Two target pictures are presented that vary along two dimensions (e.g., shape and color). Participants are asked to match a series of bivalent test pictures (e.g., yellow balls and blue trucks) to the target pictures, first according to one dimension (e.g., color) and then, after a number of trials, according to the other dimension (e.g., shape). Switch trials are also employed, in which the participant must change the dimension being matched. For example, after 4 straight trials matching on shape, the participant may be asked to match on color on the next trial and then go back to shape, thus requiring the cognitive flexibility to quickly choose the correct stimulus. Scoring is based on a combination of accuracy and reaction time, and the test takes approximately 4 minutes to administer. This test is recommended for ages 3-85.

THIS RESOURCE IS NO LONGER IN SERVICE. Documented on January 6, 2023. rOGED is a searchable database containing ovarian gene sequences, data, and images of ovarian genes expressed in rats. The site also provides customized gene expression profiles in the rat oviduct and uterus or mouse ovary. The database was constructed from total RNA isolated from intact ovaries, granulosa cells, or residual ovarian tissues collected from immature PMSG/hCG-treated rats at 0 (no PMSG), 12, and 48 h post-PMSG, as well as 6 and 12 h post-hCG. The total RNA was used for DNA microarray analysis using Affymetrix Rat Expression Arrays 230A and B. The microarray data was compiled and utilized for display of individual gene expression profiles through specially developed software. The final rOGED provides immediate analysis of temporal gene expression profiles for over 28,000 genes in intact ovaries, granulosa cells, and residual ovarian tissue during follicular growth and the preovulatory period. The accuracy of the rOGED was validated against the gene profiles for over 100 known genes. The utility of the rOGED was demonstrated by identifying seven genes which have not been described in the rat periovulatory ovary. The rOGED can be used as an instant reference for ovarian gene expression profiles, as well as reliable resource for identifying important yet, to date, unknown ovarian genes.
