Carry a big stick, or no stick at all: Punishment and endowment heterogeneity in the trust game

2016

AbstractWe investigate the effect of costly punishment in a trust game with endowment heterogeneity. Our findings indicate that the difference between the investor and the allocator’s initial endowments determines the effect of punishment on trust and trustworthiness. Punishment fosters trust only when the investor is wealthier than the allocator. Otherwise, punishment fails to promote trusting behavior. As for trustworthiness, the effect is just the opposite. The higher the difference between the investor and the allocator’s initial endowments, the less willing allocators are to pay back. We discuss the consistency of our findings with social preference models (like inequality aversion, re…

Perfiles básicos del bandolerismo morisco valenciano: del desarme a la expulsión (1563-1609)

2009

espanolA la imagen del problema del bandolerismo morisco valenciano legada por Sebastian Garcia Martinez se contrapone en estas paginas una vision alternativa, basada en el empleo de dos fuentes principales: los libros de cuentas del Maestre Racional y las conclusiones criminales de la Real Audiencia. Dos son los aspectos fundamentales que se revisan: la geografia del fenomeno, a partir de la distincion entre los lugares de origen de los fuera de la ley y los escenarios donde perpetraron sus crimenes, y su evolucion desde 1563 hasta 1609, periodo a lo largo del cual pueden diferenciarse varias fases, tanto desde la perspectiva de la actividad delictiva, como desde la de la energia represiva…

Samuel Fernberger's rejected doctoral dissertation: A neglected resource for the history of ape research in America.

2009

I summarize a never-completed 1911 doctoral dissertation on ape behavior by Samuel Fernberger of the University of Pennsylvania. Included are observations on many behavioral patterns including sensory and perceptual function, learning, memory, attention, imagination, personality, and emotion in an orangutan and two chimpanzees. There are examples of behavior resembling insight, conscience, tool use and imitation. Language comprehension was good but speech production was minimal. The document appears to contradict a brief published article on the project by William Furness in that punishment was frequently used. The document is important for understanding Fernberger's early career, for antic…

Authoritarianism and the transgenerational transmission of corporal punishment.

2019

Abstract Background Authoritarianism, firstly described by Horkheimer in 1936, is characterized by submission to authorities, aggression against subordinates and conventionalism. Authoritarianism is discussed as major contributor for right-wing attitudes. Horkheimer hypothesized that authoritarianism has its origin in the experience of harsh parenting and exposure to corporal punishment (CP) by authoritarian parents. The other way around, literature points towards an association between conventionalism and support of CP as disciplinary method, suggesting a role of authoritarianism in the vicious cycle of transgenerational transmission of CP. Objective We aimed to assess the association of a…

Linking personality and brain anatomy: a structural MRI approach to reinforcement sensitivity theory

2019

Reinforcement Sensitivity Theory (RST) proposes a widely used taxonomy of human personality linked to individual differences at both behavioral and neuropsychological levels that describe a predisposition to psychopathology. However, the body of RST research was based on animal findings, and little is known about their anatomical correspondence in humans. Here we set out to investigate MRI structural correlates (i.e. voxel-based morphometry) of the main personality dimensions proposed by the RST in a group of 400 healthy young adults who completed the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). Sensitivity to punishment scores correlated positively with the gr…

Acetaldehyde Oral Self-Administration: Evidence from the Operant-Conflict Paradigm

2011

Background: Acetaldehyde (ACD), ethanol's first metabolite, has been reported to interact with the dopaminergic reward system, and with the neural circuits involved in stress response. Rats self-administer ACD directly into cerebral ventricles, and multiple intracerebroventricular infusions of ACD produce conditioned place preference. Self-administration has been largely employed to assess the reinforcing and addictive properties of most drugs of abuse. In particular, operant conditioning is a valid model to investigate drug-seeking and drug-taking behavior in rats. Methods: This study was aimed at the evaluation of (i) the motivational properties of oral ACD in the induction and maintenanc…

2019

The ability to respond flexibly to changing environmental circumstances is a hallmark of goal-directed behavior, and compromised flexibility is associated with a wide range of psychiatric conditions in humans, such as addiction and stress-related disorders. To identify neural circuits and transmitter systems implicated in the provision of cognitive flexibility, suitable animal paradigms are needed. Ideally, such models should be easy to implement, allow for rapid task acquisition, provide multiple behavioral readouts, and permit combination with physiological and pharmacological testing and manipulation. Here, we describe a paradigm meeting these requirements and employ it to investigate th…

Acetaldehyde and Motivation

2019

Abstract Acetaldehyde contributes to alcohol’s neuroactive effects through its own motivational properties. This chapter gathers current evidence on acetaldehyde psychoactive action, focusing on behavioral investigations able to unveil acetaldehyde rewarding effects and their pharmacological modulation in vivo. Acetaldehyde induces conditioned place preference for paired environment and cues and is dose-dependently self-administered in a two-bottle choice drinking paradigm. Acetaldehyde’s motivational properties are further highlighted by operant paradigms tailored to model several addiction-like behaviors, such as induction and maintenance of operant responding, drug-seeking in extinction,…

The effects of collaboration and punishment on prospective memory performance in a group setting

2020

Contains fulltext : 225210.pdf (Publisher’s version ) (Open Access) Remembering to perform a delayed intention is termed prospective memory (PM). Often delayed intentions are shared by more than one person; however, there is a dearth of studies examining PM in social settings. We aimed to investigate whether the potential consequences of one's behavior across diverse group settings influence PM performance in event- and time-based tasks. A total of 207 participants were randomly allocated to either an individual, collaborative, or collaborative plus penalty motivation condition and were tested in a 2- or 3-person setting. For the time-based PM task, participants responded less timely in the…

Peer Discipline and Incentives Within Groups

2014

We investigate how a collusive group can sustain non-Nash actions by enforcing internal discipline through costly peer punishment. We give a simple and tractable characterization of schemes that minimize discipline costs while preserving incentive compatibility. We apply the model to a public goods contribution problem. We find that if the per-capita benefit from the public good is low, then regardless of whether peer discipline is feasible or not only small groups will contribute to the good. If the public good benefit is significant but peer discipline is infeasible it remains the case that only small groups contribute. On the other hand, if the public good benefit is significant but peer…
