A total of 22 articles were analyzed—nine with nonhumans and thirteen with humans. Procedural variables, including trial parameters, stimulus characteristics, and training and testing conditions, were documented alongside the number of participants meeting baseline, symmetry, and global equivalence criteria per experiment. Results showed that 87.5% of human participants demonstrated symmetry, while 58.81% passed global equivalence tests. Among nonhumans, 41.22% demonstrated symmetry, while transitivity was minimally explored, with a 34.83% success rate. A meta-analysis revealed correlations between trial structure, training/testing parameters, and the immediate emergence of symmetry relations in humans. Variability in outcomes across species may stem from differences in prerequisite skills or procedural inconsistencies. Standardizing parameters is essential to distinguish phylogenetic from procedural influences, as current cross-species inconsistencies confound results.

The current study was designed to extend a general discounting framework to gain insights into this fundamental trade-off process. Forty-three undergraduates adjusted the probability of receiving an immediate hypothetical monetary reward (either $200 or $10,000) until that probabilistic reward was judged subjectively equal in value to the same reward received with certainty after a delay (ranging from 1 month to 25 years). We replicated previous findings that demonstrated a linear relation between <i>log</i>(<i>delay</i>) and <i>log</i>(<i>odds-against</i>), derived from the subjective probabilistic values. This linear relation was predicted when these choices were analyzed with the hyperboloid functions that describe simple delay and probability discounting in human decision making. Additionally, we extended the discounting framework and showed that the trade-off between risk and delay was well described by a modified hyperboloid discounting model (<i>R</i><sup>2</sup>s = .99).

To test this hypothesis, we exposed 126 participants to eight, one-shot reward matrices of prisoner's dilemma games, among which socially discounted benefits and undiscounted costs systematically varied. Increasing benefits and increasing costs increased and decreased, respectively, the percentage of cooperators across the matrices. Then, 111 participants from the original sample completed one of five iterated, 40-trial reward matrices programmed to play a tit-for-tat strategy, among which benefits and costs varied. Overall, increasing benefits and increasing costs increased and decreased, respectively, cooperation across trials. This tendency, however, was more clearly observed in later than earlier trials. Both in one-shot and in iterated games, the effect of costs was greater than that of benefits and the effects of both benefits and costs decreased at extreme values. These findings suggest that cost–benefit balance, modulated by social discounting, determines degree of cooperation in both one-shot and repeated-trial cooperation tasks.</p>","PeriodicalId":17411,"journal":{"name":"Journal of the experimental analysis of behavior","volume":"124 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jeab.70046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145012097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
