The results of this study suggested that size change may contribute to the forgetting of events occurring late in development, but that neurological immaturity may underly the forgetting of earlier events. (Editor/RK)

A general hypothesis of associative learning should be based on the broadest possible foundation of empirical evidence, including confirmation in both aversive and appetitive situations. For this reason the present experiment was designed to test the surprise hypothesis using a procedure in which the unconditioned stimulus was the presentation of…

Three experiments examined predictions generated by incorporating a common-elements account of stimulus generalization within the Rescoral-Wagner model of conditioning. (Editor)

The purpose of the present experiment was to explore what it is that people remember about complex pictures. The experiment investigated several types of information which people might remember about two kinds of pictures, those which represent real-world scenes and those which represent collections of objects.

These experiments suggested that human subjects perceived velocity and acceleration directly and accurately. As well, they suggested that extrapolation of velocity is performed accurately through a direct extension of the movement that was seen. (Author/RK)

Examines the relationship between the linguistic component and the graphic component of university texts and articles. (AM)

A course and instructor evaluation model, developed at Ben Gurion University, is discussed in terms of its use as a diagnostic tool for the improvement of teaching. The evaluation model is presented as a theoretical basis for teaching diagnosis. (RAO)

Eighty-six adults serially recalled lists of visually presented consonant letters similar in auditory or visual features or dissimilar on both feature sets. There were significantly more errors at every auditory list position than at the corresponding visual and neutral list positions, which did not themselves differ. Positive correlation exists…

Levitz and Ullmann's research (1969) was replicated, based on the findings that normal subjects can increase their number of uncommon associations in response to instructions and reinforcement. Results show that normals change their responses by means of an editing process and suggests this response is a "symptom" of normal flexibility rather than…

A method of preparing computerized subject and author indexes for research and development laboratory notebooks is described. Wiswesser Line Notation is used as the subject entry capable of listing specifically and unambiguously the compounds described in the notebooks. (Author)

Three experiments investigated the relationship in speech perception between the mechanisms that determine the source of speech sounds and those that analyze their actual acoustic contents and extract from them the acoustic cues to a sound's phonetic description. (Author/RK)

The DELTA Chart acts as a communication device by displaying project needs in flow-chart form. Its five elements are: Decision box, Event box, Logic box, Time Arrow, and Activity box. It can also provide the administrator with better planning and monitoring capabilities. For journal availability see HE 509 147. (LBH)

This is Part II of a description of BASIC programming language, including explanations of "for...next" and "tab" commands. (JH)

This month's article presents three reading skills reinforcement centers that will strengthen your individualized reading program and make it more flexible. (Editor)

Together, these studies replicate and extend Gordon and Spear's (1973a) findings that proactive interference decreases as the interval between prior and subsequent learning increases and that reactivation of a prior memory just before subsequent learning significantly increases the proactive interference due to the prior learning.
