Strength-is-Weakness: The (ir)relevant relation between resources and payoffs in coalition formation

A key observation in coalition formation is that bargainers who control many resources are often excluded from coalitions by bargainers who control few resources, the Strength-is-Weakness effect. We argue that this effect is contingent on whether resources provide a legitimate claim to be included in a coalition. Across three incentivized coalition experiments (n = 2745; 915 triads), three participants (player A had four resources, player B had three resources, player C had two resources) negotiated about a payoff of 90 monetary units. Depending on condition, these resources were obtained randomly, earned, or earned and proportionally linked to the payoff. Results showed player As were less included when resources were obtained randomly and more often included in coalitions when resources were earned and/or proportionally linked to the payoff. This provides evidence that the Strength-is-Weakness is contingent on the legitimacy of the resources.     

Common knowledge of payoff uncertainty in games

Using epistemic logic, we provide a non-probabilistic way to formalise payoff uncertainty, that is, statements such as ‘player i has approximate knowledge about the utility functions of player j.’ We show that on the basis of this formalisation common knowledge of payoff uncertainty and rationality (in the sense of excluding weakly dominated strategies, due to Dekel and Fudenberg (1990)) characterises a new solution concept we have called ‘mixed iterated strict weak dominance.’     

A re‐examination of melioration and rational choice

We examined how people allocate choices between two alternatives when the payoff from each alternative varied as a function of the allocation of recent choices. On any one trial alternative A had a higher immediate payoff than alternative B, but across all trials B had a higher overall payoff than A. Rational choice theory requires that participants allocate all their responses to the alternative with the greatest overall payoff irrespective of which has the higher immediate payoff. Melioration, in contrast, proposes that participants are motivated to choose the alternative with the higher immediate payoff, irrespective of the consequences for future returns. We report four experiments in which we varied the nature of the payoffs. Participants exhibited self‐control consistent with rational choice theory when payoffs varied in magnitude, but exhibited impulsiveness consistent with melioration when the payoffs varied in probability. Finally, we show that impulsivity when payoffs varied in probability can be overcome following un‐reinforced practice. Copyright © 2002 John Wiley & Sons, Ltd.     

Cultural Difference in Hand Preference: Evidence from India and Japan

Indian (N = 400) and Japanese (N = 502) adult subjects were examined for their hand preference on a 7-point scale (1 = left always, 7 = right always) of the 32-item Waterloo Handedness Questionnaire (Steenhuis & Bryden, 1989). Factor analyses of the data yielded a two-factorial structure of hand preference: skilled and unskilled. Interaction of Culture × Hand preference indicated that Indians had more right-hand preference for unskilled activities whereas Japanese subjects had more right-hand preference for skilled activities. Further analyses revealed that the frequency of middle category responses was more common in Japanese subjects. Indian subjects were found to give more extreme responses for either right- or left-hand preference. Findings are discussed in the light of cultural training given to the individuals in these two societies, which are essentially collective in nature.     

The functions of music and their relationship to music preference in India and Germany

Is the use of music in everyday life a culturally universal phenomenon? And do the functions served by music contribute to the development of music preferences regardless of the listener's cultural background? The present study explored similarities and dissimilarities in the functions of music listening and their relationship to music preferences in two countries with different cultural backgrounds: India as an example of a collectivistic society and Germany as an example of an individualistic society. Respondents were asked to what degree their favorite music serves several functions in their life. The functions were summarized in seven main groups: background entertainment, prompt for memories, diversion, emotion regulation, self‐regulation, self‐reflection, and social bonding. Results indicate a strong similarity of the functions of people's favorite music for Indian and German listeners. Among the Indians, all of the seven functions were rated as meaningful; among the Germans, this was the case for all functions except emotion regulation. However, a pronounced dissimilarity was found in the predictive power of the functions of music for the strength of music preference, which was much stronger for Germans than for Indians. In India, the functions of music most predictive for music preference were diversion, self‐reflection, and social bonding. In Germany, the most predictive functions were emotion regulation, diversion, self‐reflection, prompt for memories, and social bonding. It is concluded that potential cultural differences hardly apply to the functional use of music in everyday life, but they do so with respect to the impact of the functions on the development of music preference. The present results are consistent with the assumption that members of a collectivistic society tend to set a higher value on their social and societal integration and their connectedness to each other than do members of individualistic societies.     

The effects of brief prayer on the experience of forgiveness: An American and Indian comparison

The present study offers a cross‐cultural examination of the effect of prayer on forgiveness. American (n = 51) and Indian (n = 100) participants either prayed for their romantic partner (prayer condition) or described their romantic partner's physical attributes (control condition). Prayers were self‐guided and lasted 3 minutes. Pre‐test and post‐test measures of retaliation were completed. Results showed that participants in the prayer group showed statistically significant decreases in retaliation motives from pre‐test to post‐test and the magnitude of this change was not different across cultures. Control groups in both cultures showed no change. Because of the religious diversity present in the Indian sample, the robustness of the effect of prayer on forgiveness was tested across Christian, Hindu and Muslim Indians. Religious affiliation did not moderate the effect of prayer on forgiveness in this sample. Results suggest that a brief prayer is capable of producing real change in forgiveness and this change is consistent across American and Indian cultures and across three different religious groups in India. Brief prayer for others that enhances forgiveness may be useful for individuals in close relationships, in certain counselling settings and for people in many different walks of life.     

Evaluating the reliance on past choices in adaptive learning models

Adaptive learning models are used to predict behavior in repeated choice tasks. Predictions can be based on previous payoffs or previous choices of the player. The current paper proposes a new method for evaluating the degree of reliance on past choices, called equal payoff series extraction (EPSE). Under this method a simulated player has the same exact choices as the player but receives equal constant payoffs from all of the alternatives. Success in predicting the next choice ahead for this simulated player therefore relies strictly on mimicry of previous choices of the actual player. This allows determining the marginal fit of predictions that are not based on the actual task payoffs. To evaluate the reliance on past choices under different models, an experiment was conducted in which 48 participants completed a three-alternative choice task in four task conditions. Two different learning rules were evaluated: an interference rule and a decay rule. The results showed that while the predictions of the decay rule relied more on past choices, only the reliance on past payoffs was associated with improved parameter generality. Moreover, we show that the Equal Payoff Series can be used as a criterion for optimizing parameters resulting in better parameter generalizability.     

Crow Indian justice: Strategies of informal social control

This study presents ethnographic findings based on fieldwork conducted on the Crow Indian Reservation in Southeast Montana. Special focus is placed on patterns of informal social control which help preserve a condition of communal harmony among reservation Indians. Aspects of kinship obligation, religion, ceremony, and personality are introduced as strategies influencing early socialization and adherence to rules. Off‐reservation problems of assimilation regarding alcohol abuse and adjustment to non‐Indian judicial systems are discussed.     

Support with Strings: Workfare as an 'Impermissible Condition'

abstract Even if a state would have been perfectly within its rights not to provide for people's welfare at all, it might still be wrong for it to exercise that discretion conditional upon something that claimants do (like ‘look for work’). What might make some conditions morally permissible and others impermissible? One answer is in terms of the consonance of the condition with the purposes of the policy. If a policy is supposed to be for one purpose — or, morally, if it can be justified only by reference to one purpose — then that policy must not impose conditions that are appropriate only to some other purpose. It is an improper exercise of power for public officials to tack wholly inappropriate conditions onto programmes justified on some other grounds altogether. Tacking labour‐market conditions onto policies that are ostensibly designed to promote people's welfare can be a case in point.     

The Intrinsic Quantum Nature of Nash Equilibrium Mixtures

In classical game theory the idea that players randomize between their actions according to a particular optimal probability distribution has always been viewed as puzzling. In this paper, we establish a fundamental connection between n-person normal form games and quantum mechanics (QM), which eliminates the conceptual problems of these random strategies. While the two theories have been regarded as distinct, our main theorem proves that if we do not give any other piece of information to a player in a game, than the payoff matrix—the axiom of “no-supplementary data” holds—then the state of mind of a rational player is algebraically isomorphic to a pure quantum state. The “no supplementary data” axiom is captured in a Lukasiewicz’s three-valued Kripke semantics wherein statements about whether a strategy or a belief of a player is rational are initially indeterminate i.e. neither true, nor false. As a corollary, we show that in a mixed Nash equilibrium, the knowledge structure of a player implies that probabilities must verify the standard “Born rule” postulate of QM. The puzzling “indifference condition” wherein each player must be rationally indifferent between all the pure actions of the support of his equilibrium strategy is resolved by his state of mind being described by a “quantum superposition” prior a player is asked to make a definite choice in a “measurement”. Finally, these results demonstrate that there is an intrinsic limitation to the predictions of game theory, on a par with the “irreducible randomness” of quantum physics.     

Children's reports of emotionally laden events: adapting the interview to the child

This study examined the influence of expressive vocabulary and temperament on children's verbal reports about emotionally laden events in different interview conditions. In one of three conditions, 58 children aged between 5 and 7 years were interviewed about a time they had felt happy and a time they had felt scared. The interview conditions were: drawing, in which they were asked to draw and tell; re‐enactment, in which they were asked to re‐enact and tell; and verbal, in which they were simply asked to tell. The principal finding was that, whereas for children in the verbal interview condition expressive vocabulary was associated with the amount of information reported and for children in the re‐enactment condition, temperament had a moderate association with the amount reported, for children in the drawing interview condition, neither temperament nor expressive language was associated with the amount of information reported. Children in the drawing condition reported more information than those in the other two interview conditions. The possible mechanisms underlying these findings and their implications for interviewing children in clinical contexts are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

‘Put Your Money Where Your Mouth Is!’: Effects of Streaks on Confidence and Betting in a Binary Choice Task

Human choice under uncertainty is influenced by erroneous beliefs about randomness. In simple binary choice tasks, such as red/black predictions in roulette, long outcome runs (e.g. red, red, red) typically increase the tendency to predict the other outcome (i.e. black), an effect labeled the “gambler's fallacy.” In these settings, participants may also attend to streaks in their predictive performance. Winning and losing streaks are thought to affect decision confidence, although prior work indicates conflicting directions. Over three laboratory experiments involving red/black predictions in a sequential roulette task, we sought to identify the effects of outcome runs and winning/losing streaks upon color predictions, decision confidence and betting behavior. Experiments 1 (n = 40) and 3 (n = 40) obtained trial‐by‐trial confidence ratings, with a win/no win payoff and a no loss/loss payoff, respectively. Experiment 2 (n = 39) obtained a trial‐by‐trial bet amount on an equivalent scale. In each experiment, the gambler's fallacy was observed on choice behavior after color runs and, in experiment 2, on betting behavior after color runs. Feedback streaks exerted no reliable influence on confidence ratings, in either payoff condition. Betting behavior, on the other hand, increased as a function of losing streaks. The increase in betting on losing streaks is interpreted as a manifestation of loss chasing; these data help clarify the psychological mechanisms underlying loss chasing and caution against the use of betting measures (“post‐decision wagering”) as a straightforward index of decision confidence. © 2014 The Authors.

Alcohol and suicide death among American Indians of New Mexico: 1980-1998

The relationship between alcohol use prior to suicide was explored among American Indian decedents in New Mexico for the years 1980 through 1998. The suicide data were collected from New Mexico Vital Statistics and toxicology reports from the New Mexico Office of the Medical Investigator and matched on a case-by-case basis. Detailed analyses were undertaken for all cases of resident New Mexico Indians from the Navajo, Pueblo, and Apache cultures. Alcohol was detected in 69% of all suicides of American Indians with some variance by major tribal cultural groups (range = 62.1% to 84.4%). This is higher than in suicides among the overall New Mexico population (44.3%). The mean blood alcohol concentration (BAC) of the drinking Indian decedents at suicide was 0.198 (+/- SD of .088). Mean BACs were high for both males (0.199) and females (0.180) who had been drinking. Over 90% of the Indian decedents who had been drinking had BACs greater than the legal intoxication level of 0.08. The Navajo had the lowest percentage of cases that were alcohol involved, and their mean BAC was lower than the other two cultural groups. Alcohol use for completed suicides also varied somewhat by age, sex, method of suicide, and place of occurrence, but very little by whether the decedent was an on or off reservation resident. Analyses indicated that alcohol use prior to suicide was significantly more associated with male suicides than for females, and it was negatively correlated for those who died by overdose and also those using other drugs at suicide. Otherwise, alcohol use did not significantly differentiate American Indian suicides by age, use of firearms, hanging, use of other methods, or residence, for the presence of alcohol was a factor very commonly associated with all of these variables. Heavy alcohol consumption is, therefore, an important factor in over two thirds of all completed suicides among the Indians of New Mexico.     

The effects of information exchange and communication in an asymmetrical negotiation situation

Seventy-eight dyads of male university students participated in a bargaining experiment. The bargaining situation was asymmetrical insofar as the two players had different payoff possibilities. Experimental instructions did not provide information about the opponent's payoff possibilities but players could ask each other for such information (except in the control condition). It was found that the players in the advantaged position (with better payoff possibilities) bluffed more frequently and communicated less with the opponent than their disadvantaged opponents. But there were no differences in the frequency of refusing to give requested information, nor in the frequency of requesting information. Verbal communication opportunities reduced the frequency of bluffing (false information) but did not by themselves lead to smaller payoff differences between the two players. Payoff differences were smallest when information exchange was obligatory and truthful and they were greatest when neither information exchange nor communication was possible.     

A one-person doxastic characterization of Nash strategies

Within a formal epistemic model for simultaneous-move games, we present the following conditions: (1) belief in the opponents’ rationality (BOR), stating that a player believes that every opponent chooses an optimal strategy, (2) self-referential beliefs (SRB), stating that a player believes that his opponents hold correct beliefs about his own beliefs, (3) projective beliefs (PB), stating that i believes that j’s belief about k’s choice is the same as i’s belief about k’s choice, and (4) conditionally independent beliefs (CIB), stating that a player believes that opponents’ types choose their strategies independently. We show that, if a player satisfies BOR, SRB and CIB, and believes that every opponent satisfies BOR, SRB, PB and CIB, then he will choose a Nash strategy (that is, a strategy that is optimal in some Nash equilibrium). We thus provide a sufficient collection of one-person conditions for Nash strategy choice. We also show that none of these seven conditions can be dropped.     

Why so curious? Validation and cross‐cultural investigation of the Hindi Epistemic Curiosity Scale

Epistemic curiosity (EC) is the motive and need to seek knowledge. The present work entails validation of the English EC Scale translated into the Hindi language. Study 1 comprised confirmatory factor analysis of the Hindi scale using a sample of 223 bilingual Indians (143 females). The 10‐item two‐factor structure with Interest and Deprivation subscales was validated for the Hindi EC Scale. Convergent and discriminant validity was established, and model fits were assessed separately for males and females, along with measurement invariance testing. In Study 2, linguistic invariance testing and cross‐cultural comparisons were undertaken for a sample of 151 Indians (93 females) and 219 Americans (179 females) for the EC scales, to assess similarities in the underlying factor structure. Indians did not differ from Americans in their responses to the English EC Scale, but slight differences were observed for the Hindi EC Scale, suggesting an interplay of language and culture. Further, independent t tests compared the two samples on measures of curiosity, gossip, personality, and affect. Americans had a higher tendency toward interpersonal curiosity and agreeableness whereas Indians scored higher on intellect. Cross‐cultural and linguistic differences as well as future work are presented. In sum, the Hindi EC Scale is a valid and reliable instrument that can facilitate further translations into other Indian languages.     

The Effect of Affective States on Selective Exposure to Televised Entertainment Fare1

Subjects were placed into a negative, neutral, or positive affective state and then, ostensibly in a waiting period, provided with an opportunity to watch television. They were free to choose among situation comedy, game show, action drama, and not watching. Time of selective exposure was measured unobtrusively. Compared to other affect-conditions, subjects in the condition of negative affect avoided comedy. Time of exposure in this condition was significantly below that in the condition of neutral affect. The tendency to avoid comedy was stable over the 10-minute test period. Compared to other affect conditions, subjects in the condition of positive affect preferred action drama. Time of exposure in this condition was significantly above that in the condition of neutral affect. Subjects experiencing negative affect watched less action drama over time; in contrast, subjects experiencing positive affect watched more action drama, but less game show. A subsequent investigation showed that hostile comedy tended to be avoided by provoked subjects specifically. Merely frustrated subjects were found to actually prefer such comedy. Furthermore, neither provoked nor frustrated subjects avoided nonhostile comedy. The findings were considered consistent with the proposal that persons select exposure to those materials that hold the greatest promise of providing prompt relief from negative affective experiences.     

Effect of racial bias on composite construction

We investigated how prior bias about a face's racial characteristics can affect its encoding and resultant facial composite construction. In total, 61 participants (24 Europeans, 18 Indians living in India and 19 Indians living in Europe) saw a racially ambiguous unfamiliar face and were led to believe it was either European or Indian. They created a composite of this face, using EFIT6. Two groups of independent raters (one Indian, the other European) then assessed the apparent race of each composite. A different two groups (one Indian, one European) assessed each composite's degree of resemblance to the target face, to determine whether this was influenced by the constructors' initial categorisation of the target face as “own-race” or “other-race.” Composites appeared significantly more “Asian” or “European” according to the bias induced in their creators, but there was no evidence of any own-race bias in the resemblance ratings for the composites.     

Individual Pathways Through the Junior-to-Senior Transition: Narratives of Two Swedish Team Sport Athletes

Athletes frequently describe the junior-to-senior transition (JST) as the most difficult within-career transition, and many athletes have acknowledged that they failed to cope well with it. Athletes’ development in the JST is influenced by narratives existing within relevant contexts and settings. This study served as a follow-up to the quantitative longitudinal study to gain a deeper understanding of individual JST paths through a qualitative narrative approach. The aim was to explore 2 team sport athletes’ (John, the football player, and Anna, the basketball player) JST pathways, emphasizing psychosocial factors that were perceived as facilitating and debilitating the process. Narrative type interviews were conducted, and the holistic-form structural analysis was used. Through their narratives, John and Anna reconstructed their JST paths, attaching meanings to certain events, recounting the people involved, and making personal reflections. John had a performance and family narrative and Anna had an enjoyment and relationship narrative. They perceived their key facilitating persons to be their family members and teammates. The debilitating factors were some coaches’ behaviors. At the time of this study, John and Anna had already terminated their athletic careers and had refocused on getting an education. Although they did not reach elite senior levels in their sports, they found their athletic careers to be meaningful life experiences.

Lay Summary: The aim was to explore two team sport athletes’ junior-to-senior transition (JST) pathways, emphasizing psychosocial factors involved in the transition process. The findings revealed two narratives. John (football player) storied his JST as a performance and family narrative and Anna (basketball player) as an enjoyment and relationship narrative.     

Similarities and Variations in Facial Expressions of Emotions: Cross-cultural Evidence

North American (Canadian) and Indian observers were shown photographs of six facial emotions; happiness, sadness, fear, anger, surprise, and disgust, expressed by American Caucasian and Indian subjects. Observers were asked to judge each photograph, on a 7-point scale, for the degree of (a) distinctiveness (free from blending with other emotion categories), (b) pleasantness-unpleasantness, and (c) arousal-nonarousal of expressed facial emotion. The results showed significant interaction of Observer × Expressor × Emotion for the distinctiveness judgement. It was found that fearful and angry expressions in Indian faces, in comparison to Caucasian faces, were judged as less distinctly identifiable by observers of both cultural origins. Indian observers rated these two emotion expressions as being more distinctive than did North Americans irrespective of the culture of the expressor. In addition, Indian observers judged fearful and angry expressions as more unpleasant than did North Americans. Caucasians, in comparison to Indians, were judged to have more arousal in most of the emotion expressions.
