In humans, drugs affect vigilance, and previous work on salticids has shown that the \"vigilance decrement\" is unlikely to be sensory habituation and that caffeine ameliorates reductions in attention. We exposed <i>Trite planiceps</i> to delta-9 tetrahydrocannabinol (THC) and methamphetamine before presenting them with a repeated visual stimulus. In the THC experiment, spiders were given a THC solution, water, or a vehicle solution, using a within-subjects design. The orienting response (i.e., \"interest\") of salticids on a track ball to face a fly stimulus presented peripherally on a monitor was scored, as well as \"general movement\" (e.g., walking, as a control for physical fatigue) and \"no movement.\" The methamphetamine experiment was identical except that salticids were given methamphetamine solution or water. In both the THC and methamphetamine treatments, general movement dropped over time, while in control treatments, this was constant. Additionally, due to an initial stimulating effect of methamphetamine on interest, the response decrement was significantly steeper when spiders were administered methamphetamine compared with water. Our results suggest that the modulation of sustained attention, and possibly motivation, is likely in salticids. basic local alignment search tool genome queries on a closely related species and pharmacological radioligand experiments suggested that salticids do not possess cannabinoid receptors, but the presence of transient receptor potential proteins may help explain the small behavioral changes observed with THC. In contrast, how methamphetamine affects salticids remains unknown.

By observing behaviors, we can understand motivational needs, decision-making processes, and preferences. Food acquisition is a survival motivator that covers a great part of daily activities, in contrast, play behavior shares a common basis with predation and social interactions. In the domestic cat, vocalizations, particularly the meow, are an acoustic signal expressing motivational and emotional states and are correlated to specific contexts, especially in cat-human interactions. This study investigated how contexts influenced meowing under two motivational conditions: feeding and play. Employing the synchronous citizen science approach, 48 guardians interacted with their cats as the researcher remotely recorded procedures involving presenting a feeder or toy and restricting access for 60 s. During the restriction periods, the cats could see and smell but not reach the stimulus. The condition influenced the frequency of meowing: they meowed significantly more in the feeding condition than in the play condition, suggesting a link between meowing frequency and the motivational context of eating, a crucial survival context. The food presentation likely influenced their motivation to vocalize. During feeding restriction, cats exhibited a significantly higher gazing at the guardian and gazing while meowing, suggesting the potential use of bimodal signals (visual and vocal) to enhance communication. In the play restriction condition, higher contact behaviors indicated a physical response to regain access, highlighting the play's social and motivational aspects. These findings help clarify contexts that motivate cats' vocalizations, aiding our understanding of their vocal communication.

The important role of facial elements (hooked beak and conspicuous eye color) in recognizing avian predators has been repeatedly demonstrated. However, no attention has yet been paid to the importance of their configuration (i.e., the mutual position of the eyes and beak). We tested the ability of untrained wild great tits to recognize a dangerous predator with its eyes rotated by 90° around its beak (inline dummy) and by 180°around its beak (invert dummy) in an outdoor aviary experiment. A dummy of a sparrowhawk with its head devoid of eyes and beak (empty dummy) served as a behavioral baseline alongside dummies of an unmodified sparrowhawk and a pigeon (as a harmless control). The tits showed no more fear toward the empty dummy than they did toward the pigeon. Toward the invert dummy, the tits showed no less fear than toward the unmodified sparrowhawk. By contrast, in the case of the inline modification, their behavior can be interpreted as increased fear. Our results do not prove that tits use holistic processing in predator recognition, but sensitivity to the presence and configuration of facial elements in the predator's face suggests that this possibility should not be ruled out.

In Experiment 1, budgerigars and pigeons were trained to discriminate whether 16 icons were the same or different from one another. When the number of icons was reduced, the discrimination tendency of both species was correlated with the entropy value, replicating previous findings. Experiment 2 further supported this correlation by controlling for the number of icons and icon patterns. However, Experiment 3 revealed that when entropy was constant, the subjects judged different more frequently for arrays with more icons per pattern, which contradicts entropy-based predictions. Notably, the response patterns of the subjects in Experiment 3 were inconsistent with logical same-different judgments, suggesting that these animals perform the MIAT based on criteria distinct from those of same-different conceptualization. These findings challenge the validity of typical MIAT for examining same-different concepts in animals and indicate the need to develop more reliable alternative methods.

In our study, we explored the personality of 27 pairs of captive coppery titi monkeys (<i>Plecturocebus cupreus</i>), using a Hominoid Personality Questionnaire of 54 personality items. We also examined the effect of pair duration, pair affiliation, and the presence of offspring on the personality of these pairs. We built a model with five components to describe titi monkey personality structure in our colony and labeled these components as aggressive, cool, cautious, innovative, and helpful. Helpful, which we relate to \"agreeableness,\" was significantly higher in males than in females. Aggressive and helpful were correlated within couples. Helpful was also negatively related to the time spent since pairing. Innovative was higher for pairs with higher affiliation. Additionally, we compared personality similarity between a group of pairs that were created based on initial compatibility (determined via a \"speed-dating\" experiment), and a group of tenure-matched pairs that were determined quasirandomly. Pairs determined from speed dating were more helpful than pairs from the colony comparison group, which suggests that high levels of initial attraction may facilitate an increase in prosocial personality traits. Our findings, including the negative correlation of \"helpful\" with time since pairing and the heightened \"innovative\" trait in pairs with stronger affiliation, may suggest subtle dynamics within titi monkey personalities.

Employing a randomized multiple simultaneous parasitism paradigm, we experimentally investigated how model egg color, dimensions, and maculation influenced the rejection rates of eight distinct egg types across 28 different pairings of two eggs at a time. First, we assessed whether egg rejection decisions depended on model egg features. Then, for a subset of trials (36%) where one egg was accepted and the other was rejected, we utilized a conjoint design analysis, a methodology borrowed from economics and marketing. Using the conjoint analysis, we showed that white model eggs were 50% more likely to be rejected relative to blue eggs, small-round eggs were 39% more likely to be rejected compared to large-elongated model eggs, and maculated eggs were 19% more likely to be rejected compared to immaculate eggs. These findings reaffirmed the roles of egg color, dimension, and maculation as key visual cues influencing egg rejection behavior in American robins.

However, the role of olfaction and vision in dogs' perception of everyday situations has been underexplored. To investigate this topic, we used a simple food-searching paradigm. A treat was hidden in one of three locations, either (a) visible from the starting point (vision condition), (b) invisible from the starting point (smell condition), or (c) invisible with an additional decoy treat presented as a distraction (fake condition). About 87 dogs of various breeds were categorized into either the olfactory-focused or the vision-focused group based on their sniffing behavior in a pretest. It was hypothesized that olfactory-focused dogs would preferentially use their sense of smell for task solving, whereas vision-focused dogs would rely more on visual information. Thus, it was expected that dogs of each group would have an advantage in the corresponding condition. However, there was no difference between groups in the duration to find the food in the three conditions. In general, food was approached faster in the vision condition, and dogs in all groups were distracted by the presence of the fake food. Thus, for all dogs, the visual sense was more dominant than the olfactory sense, and they could easily switch between using the two senses. The results are discussed in light of breed differences and general perception skills of domestic dogs.

In contrast, in patch-leaving tasks, subjects choose between staying at a patch for an SS (or LL) reinforcer and leaving for an LL (or SS) reinforcer. Previous studies show that blue jays, monkeys, humans, and rats prefer the SS reinforcer in binary-choice tasks, whereas the same subjects prefer the LL reinforcer in equivalent patch-leaving tasks. The current study systematically replicated this research using pigeons. Six pigeons responded in a binary-choice task and in two patch-leaving tasks in which staying led to an LL (Patch-L) or SS (Patch-S) reinforcer. Across conditions, the SS reinforcer delay varied from 5 to 55 s; the LL reinforcer delay was always 60 s. In binary-choice conditions, subjects preferred the SS reinforcer. In Patch-L and Patch-S conditions, subjects preferred the LL and SS reinforcer, respectively, reflecting a bias to stay at the patch. This bias persisted when the stay response was more effortful and when the delays to both reinforcers were equal. This may reflect a species-specific win-stay bias and the differential consequences of staying (which led to a stimulus signaling food) versus leaving (which led to a stimulus never associated with food). Thus, we propose a conditioned-reinforcement account of intertemporal choice in patch-leaving contexts. We suggest several avenues for further investigations of the mechanisms underlying intertemporal choice in different contexts and question the economic equivalence of the operant and patch-leaving procedures.
