The terrestrial slug "Limax" has a highly developed ability to associate the odor of some foods (e.g., carrot juice) with aversive stimuli such as the bitter taste of quinidine solution. The procerebrum (PC) is a part of the slug's brain thought to be involved in odor-aversion learning, but direct evidence is still lacking. Here, the authors…

The persistence of new memory traces in the hippocampus, encoded following appropriate activation of glutamatergic receptors and the induction of synaptic plasticity, can be influenced by heterosynaptic activation of neuromodulatory brain systems. We therefore investigated the effects of a hippocampus-specific blockade of dopamine D1/D5 receptors…

The focus of this manual is the timber wolf and its experience in the United States. The activities are designed to enable students to gain a factual understanding of the timber wolf, question any misinformation they have learned regarding wolves, and learn to appreciate the wolf as a creature of nature rather than fear it as a creature of fairy…

Article investigated the pattern of results for three series of tests in which monkeys were deprived of sight of their limbs from birth. (Author/RK)

Visual memory in monkeys was examined under four different conditions, each with a separate group. (Editor)

Predictions of two-stage learning theories were evaluated by measuring observing responses which produced the discriminative stimuli for .5 sec. (Editor)

This study is concerned with the transfer of learned helplessness from one aversive motivator, shock, to another, frustration. (Author)

The mother of a deaf preschool girl recounts how a pet kitten found by her daughter has provided the occasion and motivation for much language practice. (GW)

While responses permitting no change in location are learned very slowly, responses that allow unambiguous flight from a dangerous location are learned very rapidly. Two experiments examine the possible reinforcing properties of the flight response in avoidance acquisition. (Author/RK)

Sociobiology, although in its formative stage, is the most promising paradigm for bridging the gap between biology and the social sciences. (Author/AM)

Students of ethology are often confused about the validity of arguments based on comparisons of animal and human behavior. The problem can be dealt with purely theoretically or through observational or experimental studies of human behavior. Some results of using these two methods are described and discussed. (Author/MA)

The author examines the evolutionary and neural roots of a triune intelligence comprised of a primal mind, an emotional mind, and a rational mind. A simple brain model and some definitions of unfamiliar behavioral terms are included. (Author/MA)

Rhesus monkeys were reared in total isolation, in partial isolation, or under normal conditions with access to mothers and peers. Each group was compared on the rate of acquisition of a simple operant response. (GO)

Whether a stimulus compound is separable or integral has predictable consequences for several human information processing tasks. The purpose of these experiments was to explore the implications of this distinction for research in animal learning and the development of learning theory. (Author/RK)
