Signaled avoidance learning in crayfish (Procambarus clarkii) was investigated when the crayfish were not confined, by indexing two types of locomotive movement to the escape compartment. Mild shocks, which induced tail flipping in the crayfish, and light illumination were used as unconditioned and conditioned stimuli, respectively. In Experiment 1, two groups of crayfish were trained in a one-way shuttle box. The crayfish in Group Forward were placed in the start compartment facing the escape… Expand
Operant avoidance learning in crayfish, Orconectes rusticus: Computational ethology and the development of an automated learning paradigm
It is demonstrated that crayfish successfully learn to respond to spatially contingent cues, and a new computer framework for the automated control of learning paradigms is introduced, based on routines contained within the JavaGrinders library, which integrates real-time video tracking with robotic interfaces, and provides a suitable framework for implementing automated learning Paradigms.

Shock avoidance by discrimination learning in the shore crab (Carcinus maenas) is consistent with a key criterion for pain
Whether shore crabs placed within a brightly lit chamber learn to avoid one of two dark shelters when that shelter consistently results in shock is examined. Expand
No discrimination shock avoidance with sequential presentation of stimuli but shore crabs still reduce shock exposure
There was no discrimination shock avoidance with sequential presentation of stimuli but, consistent with pain, shore crabs used other tactics to reduce shock exposure and this behaviour is only partially consistent with the idea of pain. Expand
Pain experience in hermit crabs?
Pain may be inferred when the responses to a noxious stimulus are not reflexive but are traded off against other motivational requirements, the experience is remembered and the situation is avoidedExpand
Anxiety-like behavior in crayfish is controlled by serotonin
It is demonstrated that after exposure to stress, crayfish sustainably avoided the aversive illuminated arms of an aquatic plus-maze and this behavior was correlated with an increase in brain serotonin and was abolished by the injection of the benzodiazepine anxiolytic chlordiazepoxide. Expand
Anxiety-like behaviour increases safety from fish predation in an amphipod crustacea
It is found that this modulation of decision-making under an anxiety-like state resulted in an increased survival to predation in microcosm experiments, and calls for further investigation on the costs counterbalancing the survival benefit of an elevated anxiety level evidenced here. Expand
A Multidisciplinary Approach to Learning and Memory in the Crab Neohelice (Chasmagnathus) granulata
A number of important contributions to the field of learning and memory yielded by investigations carried out over more than 20 years in the crab Neohelice (until recently Chasmagnathus) granulata are described. Expand
Gender differences, responsiveness and memory of a potentially painful event in hermit crabs
Nonreflexive responses to a noxious event and prolonged memory are key criteria of a pain experience. In a previous study, hermit crabs, Pagurus bernhardus, that received a small electric shockExpand
Aversive responses by shore crabs to acetic acid but not to capsaicin
Responsibility to acetic acid and thus nociceptive capacity for at least some chemicals are demonstrated by testing behavioural responses of the common shore crab to two chemical irritants frequently used in vertebrate pain studies. Expand
Learning profitable habitat types by juvenile crayfish
Children of the red swamp crayfish can learn preference for habitat types based on experience with food availability, and the ability to learn the relevance of habitat features may be an important trait for the colonization success, and subsequent impact, of introduced species. Expand


Signaled avoidance in the eye withdrawal reflex of the green crab.
The results expand the range of invertebrate animals in which fundamental conditioning phenomena can be demonstrated, and may provide a neuronal model for learning in a signaled avoidance procedure. Expand
Aversive conditioning in honeybees (Apis mellifera)
Learning in honeybees, previously studied by appetitive techniques, was studied here by aversive techniques. In one series of experiments, a shuttle box was used, with the odor of formic acid as theExpand

Eye withdrawal in the green crab, Carcinus maenas was conditioned by pairing a mild vibration to the carapace as a conditioned stimulus with a puff of air to one of the eyes as an unconditioned stimulus, and this is a promising candidate for studying the neuronal basis of classical conditioning.

Species-specific defense reactions and avoidance learning.
The prevailing theories of avoidance learning and the procedures that are usually used to study it seem to be totally out of touch with what is known about how animals defend themselves in nature.Expand

The tail-flip escape reflex of the crayfish shows marked habituation and is very amenable to detailed electrophysiological study. It thus provides a model system for comprehending the neural basisExpand
Quantitative two-process analysis of avoidance conditioning in goldfish.
The shuttlebox performance of goldfish was studied under standardized conditions in a variety of problems--with or without an avoidance contingency, a conditioned stimulus (CS)-termination contingency, and an escape contingency; the good fit suggests that the theory is worth developing further with new experiments designed to challenge it. Expand
Waning of the crayfish escape response as a result of repeated stimulation.
The crayfish escape reflex is unusually amenable to detailed electrophysiological analysis, and the failure of the reflex is not efferent to the giant axons which mediate the tail-flip response and is unlikely to be due to sensory accommodation. Expand
Classical conditioning, differential conditioning, and second-order conditioning of the Aplysia gill-withdrawal reflex in a simplified mantle organ preparation.
Results of the current study show that the gill-withdrawal reflex in that preparation also underwent 2 associative forms of learning: classical conditioning and differential conditioning, and learning in the Aplysia mantle organ preparation resembled learning in vertebrates. Expand

Abstract Golden hamsters received free shock (Experiment 1) or they were partially (Experiments 2 and 3) or continuously (Experiments 4 and 5) punished with mild electric shock for face washing, openExpand
Adaptive Complexity of Interactions Between Feeding and Escape in Crayfish
Observed patterns of interaction in crayfish feeding behavior and escape from threat by tail flips suggest that the neural circuitry responsible for coordination of behavior in invertebrates may not be as simple as usually assumed. Expand
