Two experiments used simulated purchase tasks (hypothetical scenarios measuring purchasing decisions). SGMs were recruited through Reddit and LGBTQ+ community organizations across the United States. In Experiment 1, participants were randomly assigned to nine instructional sets combining varying vaccine administration modes (oral, mucosal, or subcutaneous) with different dosage schedules (one dose, two doses, or one dose annually). Experiment 2 examined how bundling HIV vaccines with one of nine health commodities affected demand. Participants also responded to questions assessing demographics, HIV risk behaviors, experiences of racial discrimination, and trust in institutions. The results demonstrated that the exponentiated demand equation effectively modeled vaccine acceptance across conditions (median <i>R</i>^<i>2</i> = 0.92). Contrary to expectations, vaccine characteristics had a minimal influence on demand (Q₀: <i>R</i>^<i>2</i> = 0.007; log α: <i>R</i>^<i>2</i> = 0.001). Instead, individual factors significantly influenced demand intensity (consumption when price = 0; Q₀) and price sensitivity (sensitivity of consumption to increasing price; α). Significant predictors of Q₀ included injection drug use history, experiences of racial discrimination, and trust in science. Low household income was the strongest predictor of log α. Bundling HIV vaccines with other health commodities showed subtle effects on acceptance, with condoms and dental examinations significantly differing from the reference category. These findings suggest that behavioral economic approaches can inform policy decisions about pricing, bundling strategies and targeted interventions to maximize HIV vaccine uptake among SGMs who face disproportionate HIV risk without requiring exposure to non-market-ready vaccines.</p>","PeriodicalId":17411,"journal":{"name":"Journal of the experimental analysis of behavior","volume":"124 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, our study used spatiotemporal data to compare the accuracy of four machine learning algorithms (i.e., logistic regression, support vector classifiers, random forests, and artificial neural networks) in detecting the presence and the components of time-based schedules in 12 rats involved in a behavioral experiment. Using spatiotemporal data, the algorithms accurately identified the presence or absence of programmed schedules and correctly differentiated between fixed- and variable-space schedules.

First, responses to the timeout lever could produce 2-min timeouts from a free-operant avoidance schedule wherein shocks could be postponed by pressing an avoidance lever. Then, timeout responding was extinguished by withholding timeouts while the avoidance response continued to postpone shocks. Finally, response-independent timeouts were delivered as the avoidance schedule remained unchanged.

Of the 75% who did not, classes emerged for 36% and 15% of participants during stacking and clustering, respectively, with a criterion of consecutive class-indicative sorts in the first two sorting tests, and by 45% and 15% of participants during stacking and clustering, respectively, with a criterion of two successive class-indicative sorts in any of the four sorting tests. Overall, a somewhat higher percentage of participants formed classes during stacking than during clustering, sometimes on a delayed basis. Finally, even higher yields were obtained when criterion was defined as two nonconsecutive class-indicative sorting tests.

Initially we asked, what do pigeons remember during the delay in delayed matching to sample: a retrospective coding of the sample or a prospective coding of the comparison-related response? This led us to examine the basis of the differential outcomes effect. Why are samples associated with differential outcomes learned faster and remembered better than samples associated with common outcomes? This research helped us discover a procedure that resulted in functional stimulus equivalence: Samples associated with the same comparison are commonly associated. This research led Peter to develop his creative model of pigeon equivalence class formation. His model predicts the conditions under which pigeons satisfy the three components of what is known as <i>Sidman equivalence</i>: reflexivity, symmetry, and transitivity, phenomena that are difficult to demonstrate in pigeons. Importantly, his model predicts the opposite of reflexivity (<i>anti-reflexivity</i>) and symmetry (<i>anti-symmetry</i>). Research confirming Peter's model laid to rest the belief that the emergent relations defining Sidman equivalence can be satisfied only by an organism capable of using language.
