In other words, the state of the temporal expectancy is not observable at every time point in the trial. On the other hand, in nature, temporal expectancies guide actions in a much more complex fashion. For instance, an animal might approach a food patch at different degrees as a function of the expected time of food availability (e.g., nectar collection behavior). The current study aimed to investigate interval timing in a more naturalistic fashion by analyzing the movement trajectory of rats in fixed time (FT-30s) vs. variable time (VT-30s) schedules in modified open field equipment. We observed a temporally patterned movement in FT but not a VT schedule. In the FT schedule, rats moved away from the reward grid after consuming the presented water and were farthest from it at around 15 s, after which they started to approach the reward grid again. There was no such temporal patterning of movement trajectory in the VT schedule. Temporal control in the FT schedule was stronger when water was delivered close to the wall compared to when it was delivered close to the center of the open field. Our results show that movement trajectory may reflect instantaneous temporal expectancy.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"230 ","pages":"Article 105233"},"PeriodicalIF":1.3,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144491549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this procedure, brief lever insertion predicts delivery of a food pellet, non-contingent upon behavior. Sign-trackers preferentially interact with the lever, while goal-trackers preferentially interact with the foodcup. To enhance motivation, rats commonly undergo mild food restriction requiring isolation housing—stressful living conditions for a social species. The present work examines the contribution of housing conditions to performance in PLA and a MWM dual solution task. Male and female rats are assigned to one of three housing conditions at weaning: Enriched (four rats per large cage with enrichment objects), Single (singly-housed standard cage with no enrichment), and Raised Enriched (raised under Enriched conditions, but transitioned to Single conditions at eight weeks). Housing conditions influence PLA performance in a sex-dependent manner. Overall, enriched rats engage in more goal-directed behavior while Single and Raised Enriched rats engage in more cue-directed behavior; this pattern is driven by male rats. Additionally, goal-trackers favor a flexible “place” strategy in the MWM. Results suggest that measures of individual differences in goal- vs. cue-directed behavior are highly sensitive to housing conditions; this sensitivity is greater in males.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"230 ","pages":"Article 105232"},"PeriodicalIF":1.3,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144330376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research in human and non-human animals has found increased levels of risky choice when audiovisual stimuli are presented with wins compared to their absence. The present study was arranged to evaluate how a visual stimulus paired with winning outcomes, and presented on some losing outcomes, would influence risky choice in rats using a probability-discounting paradigm. A choice between a smaller, certain outcome and a larger, uncertain outcome (with changing probabilities) was presented. A visual cue was always presented with winning outcomes and was systematically implemented on a proportion of outcomes where a choice was made for the uncertain alternative, but no food reinforcement was delivered. Increases in risky choice were found when the win-associated stimulus was presented on half of all losing outcomes, relative to when it was omitted. Increases in risky choice were observable when choice was between relatively equal value choices and when the value of the smaller, certain alternative was only slightly higher than that of the larger, uncertain alternative. Risky choices were also more likely following a losing trial with the presentation of the win-paired cue than following a win or a loss without the win-paired cue.

Here we sought to determine the function of antennation by investigating whether females prefer higher antennation intensity. We tested this by measuring and comparing mating behaviors of females who mated with either control males or males where one antenna had been ablated. By ablating one of the male’s antennae, we were able to manipulate the female’s perception of antennation intensity. We found that when females mated with a single male, the ablation treatment had no effect on the female preference behaviors we measured (latency to copulate, kicking behavior, and clutch size). However, when females were allowed to mate twice, once with a control and once with a manipulated male, we found that females laid more eggs when they mated with a control male. Overall, we found that females show a preference for more intense antennation behavior by increasing their clutch size when they mate multiply.

In this article, we present evidences of the long-term dynamics of the thrush nightingale singing in the Kursk region (Russia) over a period of almost half a century. The average size of individual repertoires remained relatively stable throughout the entire observation period, despite an almost twofold increase in the total size of the population's repertoire. Over 40 years (1975 – 2014), the population repertoire of song types has changed completely. For five years (2014–2018), the repertoire remained relatively stable, while in the next six years (2018–2023) there was a complete change again. Thus, the evolution of the population repertoires of the song types over time includes both periods of relative stability and periods of rapid changes up to a complete change in the composition of the dialect in just a few years. In playback experiments, we tested male response to changes in song over time to ascertain how song evolution has affected signal efficacy in male–male competition. There were no obvious differences in the response of territorial males to the playback of songs recorded in 1975 and 2023. We hypothesize that the perception of thrush nightingales is well adapted to the numerous and relatively rapid changes in the local dialect, so their response to playback does not significantly depend on the specific recording presented.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"230 ","pages":"Article 105228"},"PeriodicalIF":1.3,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding how social strategies are shaped by various potentially interacting factors is fundamental to understanding social evolution. We used highly gregarious catfish from the subfamily Corydoradinae to assess how familiarity, environmental cues, and relative body size impact coordination and communication within pairs of fish. Unlike many other model systems, Corydoradinae catfish exhibit clear inter-individual social overtures (termed ‘nudges’) that serve as an easily quantifiable measure of social motivation. Our results show that relative size was a significant predictor of individual nudges across all factor combinations, with smaller individuals nudging at higher rates than their larger partner. However, this effect was most pronounced among socially unfamiliar individuals that shared an environmental background (i.e. diet), but was largely absent when fish were familiar with one another or came from different environmental backgrounds. Cories thus appear to differ from the common behavioral model system three-spined sticklebacks in that familiarity and shared environmental background do not have the same effect on social preferences. Together these results demonstrate that relative body size is important in social interactions of these fish, but that other factors alter its impact. We thus show that individual characteristics affect social motivation in complex ways that likely influence group coordination and composition.
