The simple discrimination reversal task is a useful way to evaluate this function, as it directly measures processes related to performance change, such as sensitivity to consequences, learning set formation, and concept formation. Few studies on aging have employed this task, and those that have did not examine its component processes or include middle-aged adults. This study aimed to evaluate cognitive flexibility and its component processes through a simple discrimination reversal task, applied to 100 participants divided into four age groups: emerging adults, younger adults, middle-aged adults, and older adults. After learning three simple simultaneous visual discriminations, the function of the positive and negative stimuli was reversed three times, with participants needing to meet a performance criterion each time. Older participants were more likely to fail to meet the performance criterion in some of the reversals, a pattern consistent with reduced sensitivity to consequences and failure in class formation. Moreover, older individuals who succeeded in the task learned the new function assigned to stimuli more slowly during reversals and were less likely to form classes in the second reversal. However, all participants who met the criterion across the three reversals showed evidence of learning-set formation, regardless of age.</p>","PeriodicalId":49914,"journal":{"name":"Learning & Behavior","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach is problematic as it does not consider the decisions of the foraging animals, and little attention is given to the cognitive processes that underpin these behaviors. One such process is the ability to predict fruit availability, as this would allow animals to direct their foraging towards productive food sources and would ensure rapid seed removal when fruits are ready to be eaten. This is particularly important for species that cannot move rapidly between resources, such as tortoises. This study investigated temporal (24-h cycle) and visual cues use during food anticipation in captive red-footed tortoise (Chelonoidis carbonaria), an important seed disperser in its natural environment. A significant increase in activity was observed in the hour immediately preceding food delivery, suggesting that the tortoises learned to predict the availability of food. Test trials, in which the visual and temporal cues were put in conflict or removed, revealed that the tortoises used both sources of information to predict food availability. Moreover, extinction trials, in which the tortoises did not have reliable temporal or visual cues prior to feeding, resulted in a rapid loss of anticipatory behavior. These findings provide insights into the cognitive processes that control anticipatory foraging behavior and, as such, have important implications for both animal and plant fitness, furthering our knowledge of mutualistic services such as seed dispersal.</p>","PeriodicalId":49914,"journal":{"name":"Learning & Behavior","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145180244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zebrafish consumed significantly more food pellets and manipulated food differently when conspecifics were present, indicating that passive social facilitation due to the mere presence of conspecifics was sufficient to increase feeding behavior. Males exhibited stronger socially facilitated feeding responses, consuming more pellets, spitting pellets more frequently, and orienting food spitting away from stimulus fish, suggesting competitive motivations. Females showed more cautious feeding behavior, holding pellets in their mouths for longer.

The objectives were: to assess whether training pure tacts and intraverbals, through the inclusion of different stimuli, facilitates learning transfer to new impure tacts, and to determine whether one of these verbal operants (pure tact or intraverbal) better promotes learning transfer. The sample included 54 children aged 11-12 years, using a within-subjects experimental design with pre-post measures. The research was divided into 17 phases and six cycles, with two levels of the independent variable: (1) different stimuli in pure tacts and same in intraverbals, and (2) same stimuli in pure tacts and different in intraverbals. The presentation order was counterbalanced to control for order effects in training. Analyses using repeated-measures ANOVAs revealed that while participants could learn with either type of training, the training of pure tacts facilitated a greater learning transfer toward new impure tacts. In fact, training with pure tacts significantly increased the accuracy of responses in impure tact tests compared to intraverbal training, promoting greater generalization of learning (Pure tacts: M = 80.25%; SD = 4.04; F(1,26) = 5.44, p = .028, ηp<sup>2</sup> = .173; Intraverbals: M = 51.54%; SD = 3.65; F(1,26) = 8.33, p = .008, ηp<sup>2</sup> = .243). This finding suggests that pure tacts play a key role in promoting generative behavior, allowing the acquisition of new behavioral repertoires without explicit instruction.

Williams Animal Learning & Behavior, 19, 337-344, (1991) challenged this hypothesis in an experiment with pigeons in which Stimulus A, associated with a variable interval schedule, was always followed by Stimulus X, associated with extinction, while Stimulus B, associated with the same variable interval schedule, was always followed by Stimulus Y, also associated with a variable interval schedule. Although Williams found that most of the pigeons pecked more at Stimulus A than at Stimulus B (behavioral contrast), when the pigeons were given a choice between Stimulus A and B, they showed a preference for Stimulus B. In the present experiment (a slight modification from Williams's), we confirmed this finding. Although our pigeons pecked more at Stimulus A than at Stimulus B, they generally preferred Stimulus B, the stimulus that was not followed by extinction. This result suggests that positive contrast may not result from an increase in the subjective value of the unchanged component.
