“…The authors argue that by using such an approach they are able to quantify the motivation of the fish to avoid aversive stimuli, and also to investigate the nature of the memory associated with the avoidance response. Startle responses have also been used as a behavioural indicator to characterise the emotion of fear in fish (Davis et al 1976, Dunlop et al 2006. The fact that the fish were able to learn and modulate their behaviour to avoid aversive stimuli such as electric shocks indicates that these responses in fish can be learned and are not just reflex responses.…”

“…In a similar study, Dunlop et al (2006) compared the avoidance learning behaviour of rainbow trout and goldfish Carassius auratus. They used 2 intensities of electric shock as aversive stimuli; these were given in specific regions of an open access tank to determine whether the fish could associate a location with the electric shocks.…”

There is now compelling evidence that teleost fish possess similar nociceptive processing systems to those found in terrestrial vertebrates. Noxious stimulation of these nociceptors -specialised pain receptors -in the skin around the snout of fish generates neural activity that can be electrophysiologically recorded, and induces a number of behavioural and physiological changes. To determine whether changes in behaviour are more than simple responses to the noxious stimulation it is necessary to demonstrate that higher order cognitive processes such as mental state or 'affective state' are involved. However, quantifying the 'motivational affected state' of an animal -a concept encompassing not just pain but also fear, hunger, thirst and pleasure -is difficult owing to its subjectivity. Recent empirical work is beginning to test these concepts in fish, and we review a number of these studies and suggest how these general methodologies could be used to further our understanding of fish cognition and the capacity for fish to experience mental states such as fear or suffering.

“…In preparations that employ a shock-US, this variable has been found to be directly related to the strength of conditioning produced, an effect observed in both mammals (e.g., Annau & Kamin, 1961;Kamin & Brimer, 1963;Morris & Bouton, 2006) and fish (e.g., Dunlop, Millsopp, & Laming, 2006;Fukui & Shishimi, 1985). The present experiment was conducted to see if conditioning can be detected using the methods above, but with a lower shock intensity.…”

Barela (Psychological Reports, 110: 173-186, 2012) presented a novel preparation for the experimental study of classical fear conditioning in goldfish, and successfully employed it in the demonstration of several basic conditioning principles. The present research addressed some basic methodological questions using a modified version of this preparation. Results indicated that the modification made to the visual CS increased its efficacy, and that conditioning to this stimulus was directly related to the number of CS-US trials given, US intensity, and intertrial interval. In addition, conditioning was detected with interstimulus intervals both shorter and longer than those used previously, as well as with an auditory CS. Methodological implications for the future employment of this preparation are discussed.
