These experiments attempt to optimize the possibility of demonstrating blocking in a taste-aversion paradigm and to elucidate the conditions under which this interference occurs. (Author/RK)

To complement investigations of the direct effects of lithium toxicosis on consummatory behavior, these experiments were designed to determine the aftereffects on drinking of exposure to a conditioned stimulus previously paired with lithium. (Author/RK)

In four different experiments, brief illumination of a localized visual stimulus was followed by grain presentation unless the pigeon approached the light. Results indicate that although response-reinforcer relations do play a role, stimulus-reinforcer contingencies are the dominant factor in establishing and maintaining approaches to the…

Describes a chemistry laboratory activity for determining the best procedure for analyzing iodide in seaweed. (SL)

Describes a method of determining the molecular weight of a weak acid. (SL)

Describes four experiments in mechanics which utilize a tennis ball serving machine. (SL)

Describes the inception, use, and evaluation of a demonstration laboratory designed to enable first-year university students to observe physical phenomena that they did not observe in the secondary school. (Author/SL)

This paper is addressed to the process of learning to retrieve learned verbal material. Retrieval itself may be viewed as involving a plan or strategy for recovering the appropriate material in the particular situation for recall. (Author)

This series of experiments was designed to evaluate a model of picture and word encoding. The primary assumptions are that both sensory and semantic codes can be activated for both pictures and words but the relative order of access to phonemic information is different for the two types of representation. (Editor/RK)

Three experiments were performed to determine if the use of an organizational strategy influenced free-recall performance more than did the degree of semantic elaboration. (Editor)

This research focused on the development and articulation of the attributes given by individuals in describing others. Of special interest was the generality with which the individual uses an attribute to characterize stimulus persons. (Editor)

Described is the life cycle of the cellular slime molds Acrasiales. Experiments that can be used to explore the aggregation, migration, and culmination activities of the organism are suggested. Laboratory procedures for culturing these slime molds and listings of biological supply houses and literature references are also given. (MA)

With the development of sophisticated techniques in the biology of conception, fetal research, sustaining life after functional death, and abortion, legal and ethical questions face the medical community. (JD)

This research was a further test of the theory of constructive processes proposed by Foos, Smith, Sabol, and Mynatt (1976) to account for differences among presentation orders in the construction of linear orders. This theory is composed of different series of mental operations that must be performed when an order relationship is integrated with…

According to Barlett (1932) remembering prose is a constructive process. Meaningful material is stored in memory in schematic form and recall is achieved by a process of reconstruction. Bartlett observed that recall becomes distorted with the passage of time. This research deals with constructive remembering over time in terms that are compatible…
