為瞭解兒童在認知發展行為的表現，本研究招募國小一年級學童56名，五年級學童32名參與實驗進行。應用囚犯困境賽局與最後通牒賽局之架構設計兩個遊戲，來檢測兒童在合作與分享行為之表現。分析受試者之背叛比率、提供數量、拒絕比率等實驗資料，來檢測年齡、性別以及長幼關係是否會造成顯著影響。 實驗結果發現： （1）年齡較大兒童較傾向較合作且拒絕比率較低，這個結果和認知發展理論的結論一致。 （2）受試者資料在性別效果的假設檢定結果都不顯著。 （3）年齡較小兒童的平均提供數量都大於一半，這個結果和最後通牒賽局的理論預測相反。（4）對手為不同年齡時的背叛比率和拒絕比率都比對手為同年齡時低，這個結果支持國小開設混齡教育課程。 / This paper studies children’s behavior in an ultimatum game and a prisoner’s dilemma game with 56 children of age 7 and 32 children of age 11. With the experimental data of defect ratio, offer quantity and rejection ratio, we tested the age, sex and seniority effects under these two games. The experimental findings are as follows. （1）The older children are more cooperative and have lower rejection ratio than younger ones. These results are consistent with the developmental psychology theories. （2） We observe no significant sex effect in the three tests. （3） For younger children, the average offer quantity is higher than fifty percent, this is different from theoretical prediction and literature results.（4）We found that for pairs consisting of subjects of different ages, The defect ratio and rejection ratio are lower than pairs of the same age subjects. This evidence may provide support for mixed-age education program for some courses in elementary school.

Il presente lavoro di ricerca si è proposto di indagare i costrutti di intuizione e analisi nell’ambito del decision-making attraverso l’integrazione di differenti tipologie di dati al fine di delineare un quadro esauriente e dettagliato dell’oggetto di studio. Nello specifico, la prima parte della ricerca si è occupata dello studio di intuizione e analisi attraverso l’impiego di scale self-report. L’obiettivo generale degli Studi 1 e 2 è stato quello di verificare l’esistenza di relazioni tra differenti strumenti che, sebbene propongano definizioni e operazionalizzazioni diverse dello stesso costrutto, presentano aree di sovrapposizione. A partire da tali connessioni, ci si è, quindi, posti l’obiettivo di identificare ampi profili individuali, cognitivi e decisionali, descritti attraverso tali differenti dimensioni stilistiche. La seconda parte della ricerca si è posta l’obiettivo di indagare intuizione e analisi “in azione”, ossia di valutare il ruolo di strategie e stili individuali intuitivi e analitici nell’ambito di uno specifico contesto strategico. Focalizzando l’indagine sulla prospettiva del proposer, negli Studi 3, 4 e 5 è stato utilizzato l’Ultimatum Game come setting sperimentale. In particolare, lo Studio 3 si è proposto di verificare se le persone siano in grado di attivare processi di mindreading pertinenti per interagire con successo nel corso del gioco. Attraverso lo Studio 4, ci si è posti l’obiettivo di valutare come l’introduzione di due distinte modalità, intuitiva e analitica, di processamento delle informazioni relative all’altro giocatore influenzi le proposte monetarie. Da ultimo, nello Studio 5 ci si è focalizzati sul ruolo giocato dallo stile individuale intuitivo e analitico nell’influenzare direttamente l’entità delle offerte e nel modulare l’effetto della modalità di pensiero intuitivo e analitico. / The present work aimed at researching into the constructs of intuition and analysis in decision-making through the integration of different sources of data in order to provide a comprehensive and multifaceted outline of the issue at hand. Specifically, the first part of the investigation concerned the study of intuition and analysis by employing self-report inventories. The general purpose of the Study 1 and 2 was to verify the existence of relationships among different instruments which, even though providing varied conceptual and operational definitions of the same constructs, showed some points of overlapping. Basing on these relations the goal was, then, to identify broad cognitive and decision profiles including a set of characteristics, rather than defining individual styles through single and isolated dimensions. The second part of the investigation intended to study intuition and analysis “in action”, that is to assess the role of both intuitive-analytical strategies and individual styles within a specific strategic context. Focussing on the proposer’s perspective, Study 3, 4, and 5 all employed the Ultimatum Game as experimental setting. Study 3 aimed at assessing whether people can activate relevant mindreading processes in order to successfully interact in the course of the game. Study 4, then, investigated how the monetary proposals were affected by the introduction of two distinct modes, intuitive and analytical, of processing information about the counterpart. Finally, in Study 5, the role of individual intuitive and analytical style in directly influencing the entity of the offers and, in case, modulating the effect of the intuitive and analytical modes of thinking was examined.

La tesi presenta alcuni dei risultati di un esperimento longitudinale condotto in due carceri statunitensi tra settembre 2015 e giugno 2016. L’obiettivo dell’analisi è testare lo studio delle preferenze sociali nella cornice dell’Economia Comportamentale e della teoria dei giochi (osservazione diretta del comportamento dei soggetti chiamati a compiere delle scelte in alcune situazioni selezionate), piuttosto che attraverso risposte a questionari auto valutativi. Infatti vengono messe in relazione i comportamenti osservati nei giochi e le spiegazioni che i soggetti intervistati danno di essi. Attraverso analisi statistica si può arrivare a dire che i comportamenti osservati nei giochi non sono sempre sufficienti per evidenziare le preferenze sociali dei soggetti, così come, del resto, non lo sono le risposte narrative. La conclusione che viene tratta dall’elaborato è che osservazione diretta dei comportamenti e analisi delle narrative personali dei soggetti sono due elementi ugualmente importanti per la comprensione delle preferenze sociali e che, lungi dall’escludersi a vicenda, si completano. / The thesis presents some of the results of a longitudinal experiment conducted in two U.S. prisons between September 2015 and June 2016. The objective of the analysis is to test the efficacy of studying social preferences in the framework of behavioral Economics and game theory (direct observation of the behaviour of the subjects asked to make choices in real situations), rather than through self-evaluative questionnaires and surveys. In fact, the analysis links the behaviors observed in the games and the explanations given by the subjects. In general it can be said that the behaviors observed in the games are not always sufficient to highlight the social preferences of the subjects, as well as, moreover, are not the narrative answers. The conclusion that comes from the elaborate is that direct observation of the behaviors and analysis of the personal narratives of the subjects are two equally important tools in the study social preferences and that, far from being mutually exclusive, they complement each other.

[pt] O objetivo deste trabalho é aplicar a Teoria dos Jogos como elemento motivador no ensino da Matemática em turmas da terceira série do ensino médio de uma escola estadual da cidade do Rio de Janeiro, que apresentam com grande frequência dificuldades no aprendizado desta disciplina. Construímos então uma sequência didática a ser realizada em sala de aula: apresentação de breve histórico da teoria, realização do jogo Dilema do Prisioneiro e posterior explicação sobre os resultados previstos pela teoria para este jogo, introduzindo os conceitos de matriz de ganhos e estratégia dominante. Em seguida foi aplicado um teste simples de auto-avaliação, para fixação dos tópicos apresentados anteriormente. Assumindo então que neste momento os alunos estão familiarizados com os conceitos mais simples da Teoria dos Jogos, realizamos em sala de aula o jogo Barganha com Ultimato, para posterior comparação de resultados com aqueles obtidos por Bianchi, Carter e Irons e Castro e Ribeiro. / [en] The objective of this study is to apply Game Theory as a motivating element in the teaching of mathematics in those classes in the 3rd series of secondary education in the state schools of the city of Rio de Janeiro which have already frequently presented difficulties in learning this discipline. We construct a didactic sequence to be applied in the classroom: presentation of a brief history of the theory; the realisation of the game, the Prisoner s Dilema; and a subsequent explanation of the results predicted by Game Theory for this game, introducing the concepts of the result matrix and the dominant strategy. We then apply a simple self-assessment test in order to consolidate these topics. Once the students are familiarised with the basic concepts of Game Theory, we realise the Ultimatum Game in the classroom in order to compare the results with those obtained by Bianchi, Carter e Irons and Castro e Ribeiro.

[pt] O objetivo deste trabalho é investigar como os alunos do Ensino Médio da rede pública estadual de ensino do Rio de Janeiro se comportam com a aplicação da Teoria dos Jogos como elemento motivador no ensino da Matemática, uma vez que apresentam, com grande frequência, dificuldades nesta disciplina. Para atingir o objetivo proposto elaboramos uma sequência didática que consistia na realização dos jogos Barganha com Ultimato e Dilema do Prisioneiro em sala de aula, sem qualquer explicação prévia sobre os conceitos básicos da Teoria dos Jogos. Nesta sequência didática, após a realização de cada jogo explicamos os resultados previstos pela teoria, introduzindo os conceitos de matriz de ganhos, estratégia dominante e equilíbrio de Nash, e explicamos o funcionamento do jogo Pôquer Simplificado com seus resultados teóricos. Ao término da aplicação da sequência didática, realizamos um teste de auto-avaliação simples, para que pudéssemos verificar o nível de aprendizado dos alunos envolvidos. Por fim, comparamos os resultados obtidos pelos pares de alunos que participaram do jogo Barganha com Ultimato (realizado quando ainda não possuíam qualquer experiência em Teoria dos Jogos) com aqueles obtidos por Bianchi, Carter e Irons e Castro e Ribeiro. / [en] The objective of this work is to investigate the effect of game theory as a motivator for mathematics education on those second year high school students in the state public schools of Rio de Janeiro who have already shown frequent difficulties with the discipline. In order to achieve the proposed goal, we develop a didactic sequence involving the application in the classroom of the games the Ultimatum Game and the Prisoner s Dilema without any prior introduction to the basic concepts of game theory. After the completion of each game, we explain the results predicted by the theory, introducing the concepts of the payoff matrix, the dominant strategy and the Nash Equilibrium. In addition, we explain the operation of the game of Simplified Poker along which its theoretical results. Upon completion of the application of this didactic sequence, we apply a simple self-evaluation test in order to verify the academic level of the students involved. Finally, we compare the results obtained by the pairs of students who participated in the game the Ultimatum Game (performed when the students still had no experience of Game Theory) with the results obtained by Bianchi, Carter e Irons and Castro e Ribeiro.

Robots and virtual agents grow rapidly in behavioural sophistication and complexity. They become better learners and teachers, cooperators and communicators, workers and companions. These artefacts – whose behaviours are not always readily understood by human intuition nor comprehensibly explained in terms of mechanism – will have to interact socially. Moving beyond artificial rational systems to artificial social systems means having to engage with fundamental questions about agenthood, sociality, intelligence, and the relationship between mind and body. It also means having to revise our theories about these things in the course of continuously assessing the social sufficiency of existing artificial social agents. The present thesis presents an empirical study investigating the social influence of physical versus virtual embodiment on people's decisions in the context of a bargaining task. The results indicate that agent embodiment did not affect the social influence of the agent or the extent to which it was perceived as a social actor. However, participants' perception of the agent as a social actor did influence their decisions. This suggests that experimental results from studies comparing different robot embodiments should not be over-generalised beyond the particular task domain in which the studied interactions took place.
