Associative learning: Box jellyfish learns to avoid bumps

Current Biology, 2023
Operant conditioning - learning to do something for a desired outcome - has never been convincingly demonstrated in Cnidaria. A study now shows that box jellyfish, Tripedalia cystophora, can learn to avoid bumping into an obstacle based on visual cues.

Learning to Avoid Extremism

Educational Theory, 2023
AbstractDemocracies are calling on schools to respond to a rise in extremist ideologies and actions. In this article Sigal Ben‐Porath situates the rise in extremism within the broader context of political polarization. She suggests that the latter is a more appropriate target for school intervention than the former. She further suggests that addressing

GALVANIC SKIN RESPONSE DURING AVOIDANCE LEARNING

Psychophysiology, 1966
ABSTRACTRelations between galvanic skin response (GSR) and other variables during learning of a shock‐avoidance task were observed. Ss operated a four‐position switch as cued by visual stimuli: one always shocked, one never shocked, and two associated with switch positions which avoided the shock.

Forebrain serotonergic involvement in avoidance learning

Neuroscience Letters, 1985
The one-way active avoidance deficit caused by the serotonergic (5-HT) releasing compound p-chloroamphetamine (PCA) was examined in rats after degeneration of 5-HT neurons in the forebrain. Injection of 5,7-dihydroxytryptamine (5,7-DHT) into the forebrain in desipramine (20 mg/kg)-pretreated rats resulted in a 65-70% decrease in 5-HT concentrations in ...

Alcoholism, Avoidance Learning and Emotional Responsiveness*

British Journal of Social and Clinical Psychology, 1966
Two groups of alcoholics, one consisting of clinic patients and one of chronic drunkenness offenders, were compared with two groups of nonalcoholic subjects (students and unemployed workers) in respect to their ability to learn to avoid pain‐producing stimuli.

Learning implicitly to produce avoided behaviours

Quarterly Journal of Experimental Psychology, 2011
The literature on repetition processing reveals an intriguing paradox between the particular salience of repetitions, which makes them easy to learn, and a tendency to avoid them when generating sequences. The aim of this experiment was to study the extent to which children can learn to produce these avoided behaviours by means of an artificial ...

Avoidance Learning to Aversive Brain Stimulation

Psychological Reports, 1962
While training rats for self-stimulation of the brain, it was observed in 3 rats rhar the intra-cranial stimulation (ICS) was noxious. Two of the animals jumped completely out of the Skinner box at the onset of a current as low as 20 pA.

The Avoidance Learning Problem

1972
Publisher Summary This chapter focuses on the avoidance learning problem. The first form the problem of avoidance learning took was quite unrecognizable. A human S's finger was placed on a metal electrode and after a 2-second conditioned stimulus (CS), or warning stimulus, electricity from an inductorium is applied. The unconditioned response (US) is

Hormones and Avoidance Learning

1975
Hormonal involvement in learning processes is most likley to take one of two forms. First, as the previous chapter has shown, hormones in the form of neurotransmitters could underlie the formation and maintenance of memory traces themselves and play a major role in the neural organization of information as well. Second, hormones can affect the learning
