The Children's Auditory Discrimination Inventory (CADI) was used in the longitudinal study to evaluate the child's ability to identify, between two pictures that have been given oral word equivalents, the picture that represents the orally presented stimulus word. The task, which takes 10 minutes, uses 38 cards with two pictures on each and 38…

The Johns Hopkins Perceptual Test, a brief measure of intelligence in children, requires the child to choose a form identical to a standard. It consists of 3 practice and 30 test items, all involving black geometric figures printed on white cards. There is one booklet for stimulus cards and one for response cards. The child is presented with a…

An adaptation of a technique devised by Mischel (1958) was used in the longitudinal study to measure delay of gratification. Adaptations involved (1) asking the child to identify the larger of two pieces of candy to facilitate comprehension of the rewards, (2) specifying a standard time limit for receipt of the delayed reward which would be…

Data obtained from the administration of the Brown IDS Self-Concept Referents Test as part of the longitudinal study are provided and discussed. The Brown IDS Self-Concept Referents Test is a technique for assessing self-concept which uses a photograph of the young child to induce him to take the role of another toward himself. While looking at…

The Form Reproduction task was included in the longitudinal study test battery to: (1) examine visual-motor performance over time; (2) study processes associated with visual analysis and synthesis and visual-motor integration; and (3) examine its predictive validity for later academic/skill behaviors, e.g., writing. Form Reproduction in Year 1…

The Massad Mimicry Test is an individually administered task for 3-1/2--4-1/2 year-old children. Part I evaluates the child's ability to reproduce phonemes in 30 nonsense words upon hearing each no more than three times from a tape recorded model. Similarly, Part II assesses the child's ability to reproduce meaningful words and phonemes as they…

The Sigel Object Categorization Test (SOCT) is used for studying classification abilities in young children, the criteria for which is considered indicative of both cognitive ability and style. The test consists of two types of stijuli--one set of 12 relatively familiar three-dimensional objects and a second set of colored photographs of these…

The fixation task used in this study measures the amount of time a child fixates or looks at a given picture as it is repeated over six trials and then is followed by a novel picture on the seventh. Two series of slides were used. The first was a redundant nonsocial visual stimulus: six trials of a slide showing 20 chromatic straight lines and a…

The TAMA was designed specifically for the Longitudinal Study as a nonverbal test of general knowledge. The test requires the child to point to the correct picture among three alternatives in response to a question. The two practice items and 25 test items are printed on bound cards, mostly in black and white. Items can be classified as follows:…

The Seguin Form Board Test is used to assess visual discrimination and matching and eye-hand coordination. Previous analysis has shown the vactor loadings for the same scale to differ among age levels, so the test may be measuring different abilities at different age levels. Test materials consist of ten differently shaped wooden blocks and a…

Risk-Taking 2 investigates behaviors of young children who are presented with a choice without prior knowledge of the outcome. The child is asked to choose between a certainty, a toy placed in front of him, and an uncertainty, a paper bag which E had previously explained might contain five toys or none at all. Children who chose the certain toy…

This is the second of two measures designed for this study to test the child's vigor. The measure consists of instructing the child to turn a large wooden crank, mounted on a stand, as fast as he can until the E says to stop. Two trials of 15 second each, preceded by a practice trial, were presented. The score was the number of turns completed in…

The Preschool Inventory is the task in this battery most clearly associated with general cognitive development. It measures a range of verbal, quantitative, and perceptual-motor skills. The Inventory was first developed as a general achievement measure for Head Start children. The 1970 edition of the Inventory contains 64 items in four areas:…
