“…We think that this active and prolonged scanning behavior is fundamental for the process of learning novel visual stimuli, as well as in novel detours. In the study by Bednarski et al (2012), described in the introduction, the spiders had no possibility of engaging in this visual inspection, given the fact that the stimuli were moving.…”

“…We tested Phidippus regius (Koch, 1846), a species belonging to the family of Salticidae that has been successfully tested through a variety of methodologies, such as conditioning (Jakob, Skow, Haberman, & Plourde, 2007;Liedtke & Schneider, 2014;Peckmezian & Taylor, 2015a), using simulated environments (Peckmezian & Taylor, 2015b) and even using neurophysiological recording techniques (Menda, Shamble, Nitzany, Golden, & Hoy, 2014). A previous study (Bednarski, Taylor, & Jakob, 2012) tested the ability of jumping spiders to discriminate between the moving image of a cricket (meaningful) and a moving rectangle (abstract), but the animals seemed unable to learn to discriminate between the two. However, the focus of the experiment was the detection of the motion of stimuli, rather than their shape.…”

“…Our experiment demonstrates that vibration provides an alternative to another proven aversive stimulus, shock (e.g., Skow 2007;Bednarski et al 2012). Shock has several drawbacks that vibration does not share.…”

Previous work has shown that jumping spiders are able to associate visual cues with shock. We tested the efficacy of vibration as an aversive stimulus. Phidippus audax (Hentz 1845) (Salticidae) were first allowed to choose between two video stimuli, a cricket and an oval. We then tethered spiders so they were oriented toward their preferred stimulus with their tarsi touching a platform, either vibrated by a motor (experimental group) or with the motor turned off (control group). Spiders were then given a second opportunity to choose between the stimuli. Experimental spiders were significantly less likely to choose the stimulus that they viewed during training compared to control spiders. Spiders stalked and ate prey soon after experiencing the training procedure, suggesting that vibration caused no lasting harm. In addition, freely moving spiders avoided a vibrating platform, supporting the assertion that the vibration itself is aversive.

“…However, caution is needed before accepting null hypotheses and we are reluctant to suggest, on the basis of non-significant findings, that C. gibbosus and P. wanlessi are simply incapable of solving novel problems by trial and error or that these two species have no capacity for operant conditioning. There has been longstanding interest in determining the capacity that insects and spiders express for various categories of learning (Dukas 2008; Bednarski et al 2012; Liedtke and Schneider 2014), including operant conditioning (Skinner 1938), and we expect operant conditioning to be within the capacity of almost any insect or spider.…”

Solving a novel confinement problem by spartaeine salticids that are predisposed to solve problems in the context of predation

Especially intricate predatory strategies are widespread in the salticid subfamily Spartaeinae. The hypothesis we consider here is that the spartaeine species that are proficient at solving prey-capture problems are also proficient at solving novel problems. We used nine species from this subfamily in our experiments. Eight of these species (two Brettus, one Cocalus, three Cyrba, two Portia) are known for specialized invasion of other spiders’ webs and for actively choosing other spiders as preferred prey (‘araneophagy’). Except for Cocalus, these species also use trial-and-error to derive web-based signals with which they gain dynamic fine control of the resident spider’s behaviour (‘aggressive mimicry’).The ninth species, Paracyrba wanlessi, is not araneophagic and instead specializes at preying on mosquitoes. We presented these nine species with a novel confinement problem that could be solved by trial and error. The test spider began each trial on an island in a tray of water, with an atoll surrounding the island. From the island, the spider could choose between two potential escape tactics (leap or swim), but we decided at random before the trial which tactic would fail and which tactic would achieve partial success. Our findings show that the seven aggressive-mimic species are proficient at solving the confinement problem by repeating ‘correct’ choices and by switching to the alternative tactic after making an ‘incorrect’ choice. However, as predicted, there was no evidence of C. gibbosus or P. wanlessi, the two non-aggressive-mimic species, solving the confinement problem. We discuss these findings in the context of an often-made distinction between domain-specific and domain-general cognition.
