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)

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)

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. (Author/RK)

Experimenters in the past have reported that when insulin is used as the unconditioned stimulus (US), rats will learn an aversion to a sodium chloride but not a sucrose solution, whereas with formalin as the US, they will learn an aversion to a sucrose but not a saline solution. The present experiments failed to confirm these findings. (Editor)

These experiments investigate the degree to which neophobia, the reluctance to consume novel food, can be modified by toxicosis, the conditions under which the contingency between ingestion and illness enhances neophobia, and the manner in which previously learned aversions mediate subsequent enhanced neophobia. (Author/RK)

These experiments investigate situations in which a negative correlation involves a 24 hour delay between the occurrence of a conditioned stimulus and an unconditioned stimulus; they also investigate the mechanism by which any inhibition so produced might occur. (Author/RK)

This research has three purposes: 1) to determine whether subjects instructed to study silently in a free-recall experiment engage in associative encoding, 2) to test the validity of associative ability as an individual difference variable, 3) to test for an interaction between presentation rate and associative reaction time. (Editor/RK)

From experiments showing that subjects differentially attend to parts of the visual field, psychologists have inferred a limitation on human visual information processing capacity. The model presented describes an optimal way to allocate a limited quantity of "cognitive resources", "attention" or "mental effort". An experiment tests this model.…

Presents an overview and an example of use of the Information-Visualization System, an approach to visual selection enabling educators to match desired learning outcomes with the best visuals to carry the message. Decision tables and resource book containing visual options, information types, and suggested methods of enhancing visuals are…
