Effect of opponent type on moral emotions and responses to video game play

This study suggests that fighting against different types of opponents in video games (e.g., human opponents vs. monster opponents) may lead to different emotional responses and moral judgments toward game characters. Based on Bandura's moral disengagement theory, this study proposes that shooting at monster opponents makes game players feel less guilty and judge the player-controlled character as more morally justified. An experiment was conducted in which participants played shooting games with either human opponents or monster opponents. The results show that when playing against monster opponents, participants felt both less ashamed and less guilty, reported enjoying the game more, and judged their character as more justified than participants who played against human opponents.     

PAKISTAN AND SIKH NATIONALISM: STATE POLICY AND PRIVATE PERCEPTIONS

The paper will examine Pakistan policies and perceptions of Sikh nationalism in the period from 1947 until the present day. The policies, it will be argued, have been opportunistic rather than strategic and have embraced both covert support for militancy against the Indian state in the 1980s and the attempt to use Sikhs and East Punjab as a bridge between Pakistan and India in the post-2001 period of composite dialogue. Private perceptions will be explored first through the accounts of partition survivors. They contain a typical mixture of romanticized views of Muslim–Sikh rural harmony before 1947 and of the Sikhs as an aggressive ‘Other’ in the ‘War of Religions’ at the time of the massacres and mass migrations. Their official counterpart is the attempt to ‘blame’ Sikhs for the violence and to understand the attacks in East Punjab as part of a Sikh Plan of ethnic cleansing. Secondly, private perceptions will be examined in terms of accounts written at the time of the 1980s Punjab crisis. These Pakistani works support the view of Sikhs as an ‘aggrieved minority’. Sympathy for Sikh nationalist struggle stops short of overt support for the militants in such texts. They frequently indulge, however, in attacks on the ‘Brahminical’ hegemony within India, thus echoing Sikh ethno-nationalist writings. Contemporary writings are suffused with romanticist imaginings of the Punjab, bringing harmony to the region in which the ‘love’ aspect of the love/hate relationship between Punjabi Muslims and Sikhs is emphasized. The extent to which the two Punjabs have drifted away from each other since partition is seldom acknowledged; nor the history of competing Muslim and Sikh nationalisms in the region.     

Intrasexual interactions among female golden hamsters (Mesocricetus auratus) over the estrous cycle

Social interactions of cycling female golden hamsters paired with ovariectomized animals in large enclosures were primarily agonistic over the 4-day estrous cycle. These aggressive interactions were intense as indicated by frequent occurrences of chase and flight behavior. Dominant and subordinate social ranks were established in the majority of pairs (96%) tested, and even females in sexual heat were capable of attacking and dominating their rivals. Furthermore, cycling females exhibited significantly more aggressive acts than ovariectomized opponents 1 day prior to sexual receptivity. No differences in fighting patterns were found between animals on the other 3 days of the estrous cycle. Additional analyses revealed clear differences in agonistic elements, including flank marking, between dominant and subordinate females regardless of whether they were gonadectomized or intact. These analyses also showed that dominant individuals frequently chased and bit opponents during encounters within their nesting area. The data are examined for implications on the adaptive organization of female hamster agonistic behavior and the neuroendocrine regulation of species-typical behavior over the estrous cycle.     

Wrestling the Serpent: Gandhi,Amritsar and the British Empire

Throughout the period of the non‐co‐operation movement in India in the early 1920s, Gandhi surprised and sometimes bewildered the British in India with his incessant labelling of the Government as ‘satanic’. It is argued in this paper that Gandhi deliberately employed the word ‘satanic’ with a keen awareness of its power on both his opponents and supporters. He used it to give religious justification to the non‐co‐operation movement. He used it to apportion guilt and spread disaffection with the British Government. He used it to exhort his followers to greater self‐purification, especially against the ‘weaknesses’ of violence and untouchability.     

Checkmate? The role of gender stereotypes in the ultimate intellectual sport

Women are surprisingly underrepresented in the chess world, representing less that 5% of registered tournament players worldwide and only 1% of the world's grand masters. In this paper it is argued that gender stereotypes are mainly responsible for the underperformance of women in chess. Forty‐two male–female pairs, matched for ability, played two chess games via Internet. When players were unaware of the sex of opponent (control condition), females played approximately as well as males. When the gender stereotype was activated (experimental condition), women showed a drastic performance drop, but only when they were aware that they were playing against a male opponent. When they (falsely) believed to be playing against a woman, they performed as well as their male opponents. In addition, our findings suggest that women show lower chess‐specific self‐esteem and a weaker promotion focus, which are predictive of poorer chess performance.

The effect of manipulating context-specific information on perceptual-cognitive processes during a simulated anticipation task

We manipulated contextual information in order to examine the perceptual-cognitive processes that support anticipation using a simulated cricket-batting task. Skilled (N= 10) and less skilled (N= 10) cricket batters responded to video simulations of opponents bowling a cricket ball under high and low contextual information conditions. Skilled batters were more accurate, demonstrated more effective search behaviours, and provided more detailed verbal reports of thinking. Moreover, when they viewed their opponent multiple times (high context), they reduced their mean fixation time. All batters improved performance and altered thought processes when in the high context, compared to when they responded to their opponent without previously seeing them bowl (low context). Findings illustrate how context influences performance and the search for relevant information when engaging in a dynamic, time-constrained task.     

Exploration evoked by the environment is balanced by the need to perform in cricket spin bowling.

In the theory of ecological dynamics, adaptive responses emerge through exploration when an individual interacts with their environment. This study investigates how when competing, the environment guides perceptual-motor exploration that is balanced by the need to meet performance requirements. To understand this, eight emerging expert cricket spin bowlers aged 21 ± 3 years competed in three small-sided simulated practice matches where pitch conditions were manipulated to present familiar and unfamiliar environmental pitch constraints. It was hypothesized that bowlers would explore the unfamiliar pitch by searching for an action mode that allowed them to best exploit the conditions to achieve a successful outcome (e.g., take a wicket) while simultaneously attempting to satisfy the immediate performance requirements (e.g., limit runs per over). A mixed methodology was used to first identify the perceptions and intentions of the bowlers (dimensions, themes, and action modes), followed by analysis of the resultant action characteristics (delivery speed, spin rate, and pitching position) and performance outcomes (economy rate, strike rate, and bowling average). Overall, when competing on the familiar pitch, the bowlers reported primarily attuning to task constraints (75%). In contrast, when bowling on the unfamiliar pitch, all bowlers reported that their attention was more focused upon picking up key affordances related to environmental pitch constraints (100%). The majority of bowlers indicated that they bowled differently on the unfamiliar pitch by using more “side-spin” and less “over-spin”. Interestingly, it was not until the second performance on this pitch that execution variables significantly changed. Despite these changes, bowlers continued to pay attention to the opposing batters’ strategies throughout all three practice matches. The consistency of this response can be explained by an overarching strategy for all types of bowling in cricket that is more closely linked to the ongoing individual-opponent interaction. That is, the bowlers must perform and ‘stay in the game’ whilst simultaneously adapting to any environmental changes. Therefore, demonstrating the need to continually satisfy the immediate performance requirements to afford the opportunity to explore new affordances in the environment that may offer exploitation.     

Women's reactions to discrimination from members of the same or opposite sex

The effects upon women's self-evaluations of experiencing varying severity of failure in interpersonal competition against male vs. female opponents were explored. The results supported the hypothesis that self-esteem in women is more vulnerable to interpersonal rejection from men as opposed to other women. Specifically, subjects reported lower self-esteem when severe failure was due to the actions of alleged, male opponents rather than female ones. Also, severe failure elicited less favorable self-evaluations than mild failure only when the female subjects confronted male opponents. Finally, contrary to a defensive self-presentation hypothesis, subjects did not respond to discrimination from men by presenting themselves as being discrepant from the stereotype of women. Instead, subjects who interpreted their failure as reflecting prejudice on the part of men evaluated themselves more favorably on positive traits underlying the female stereotype.     

Materialism in the mainstream of early German philosophy

ABSTRACT

Discussions of the reception of materialist thought in Germany in the first half of the eighteenth century tend to focus, naturally enough, upon the homegrown freethinkers who advanced the cause of Lucretius, Hobbes, and Spinoza in clandestine publications and frequently courted the ire of the state for doing so. If the philosophers belonging to the mainstream of German intellectual life in that period are accorded a place in the story, it is only insofar as they actively set themselves against the materialist threat and, in the course of working to undermine it, actually only succeeded in inadvertently drawing more popular attention to it. By contrast, in this paper I will show that it was not just insofar as the thinkers of the early eighteenth century played the role of the diligent critic and unwittingly propagated the views of their opponents that materialism can be said to have penetrated into the very mainstream of the German Enlightenment. Rather, as I will argue, there was a striking degree of uptake of distinctively materialist claims even among its most vociferous mainstream critics, and that this is the case for thinkers in both the Wolffian and the Thomasian traditions.     

Analysis of the evolution of soccer at the world championships

This research follows the line of investigation opened some years ago about the generalizability studies and variance components applied to soccer. In this investigation, various matches played during the final phase of the last three World Championships (France'98, Korea and Japan'02 and Germany'06) were observed and coded while their interaction contexts were registered. In total, 58 matches were used for this investigation. The following facets were considered: 5 field areas where the 48 contexts are moved or transformed and 7 different types of match result. The results confirm the linear model, which can be generalized to the universe. The resulting 1% of the variance explained by the World Championship facet (1 point when analyzed singly and 14 points when it interacts with the other facets) allows us to confirm that soccer has not changed over the last three World Championships.     

Third party instigation of aggression as a function of attack and vulnerability

Subjects serving as advisors instructed a confederate which shock intensity to deliver to an opponent in a reaction-time competition; subjects could also directly aggress by setting shock for the opponent's partner. Vulnerable subjects (shock electrode on) both instigated less aggression, i.e., suggested that less intense shocks be set, and directly aggressed less frequently than nonvulnerable subjects (no shock electrode). Attacked subjects, those for whom the opponents set shock, both instigated more aggression and more frequently set shock than did nonattacked subjects. The relationship between vulnerability and attack was additive for instigative aggression and multiplicative for direct aggression. Both modes of aggression were significantly influenced by the intensity of provocation from the opponents.     

Lightness constancy and illumination discounting

Contrary to the implication of the term "lightness constancy", asymmetric lightness matching has never been found to be perfect unless the scene is highly articulated (i.e., contains a number of different reflectances). Also, lightness constancy has been found to vary for different observers, and an effect of instruction (lightness vs. brightness) has been reported. The elusiveness of lightness constancy presents a great challenge to visual science; we revisit these issues in the following experiment, which involved 44 observers in total. The stimuli consisted of a large sheet of black paper with a rectangular spotlight projected onto the lower half and 40 squares of various shades of grey printed on the upper half. The luminance ratio at the edge of the spotlight was 25, while that of the squares varied from 2 to 16. Three different instructions were given to observers: They were asked to find a square in the upper half that (i) looked as if it was made of the same paper as that on which the spotlight fell (lightness match), (ii) had the same luminance contrast as the spotlight edge (contrast match), or (iii) had the same brightness as the spotlight (brightness match). Observers made 10 matches of each of the three types. Great interindividual variability was found for all three types of matches. In particular, the individual Brunswik ratios were found to vary over a broad range (from .47 to .85). That is, lightness matches were found to be far from veridical. Contrast matches were also found to be inaccurate, being on average, underestimated by a factor of 3.4. Articulation was found to essentially affect not only lightness, but contrast and brightness matches as well. No difference was found between the lightness and luminance contrast matches. While the brightness matches significantly differed from the other matches, the difference was small. Furthermore, the brightness matches were found to be subject to the same interindividual variability and the same effect of articulation. This leads to the conclusion that inexperienced observers are unable to estimate both the brightness and the luminance contrast of the light reflected from real objects lit by real lights. None of our observers perceived illumination edges purely as illumination edges: A partial Gelb effect ("partial illumination discounting") always took place. The lightness inconstancy in our experiment resulted from this partial illumination discounting. We propose an account of our results based on the two-dimensionality of achromatic colour. We argue that large interindividual variations and the effect of articulation are caused by the large ambiguity of luminance ratios in the stimulus displays used in laboratory conditions.     

No expectation bias in elite-level cricket umpires’ leg-before-wicket (LBW) decisions according to batting order position

ObjectivesPrevious studies have shown that sport officials’ decisions can be impacted by biases associated with expectations. The aim of this study was to determine whether elite cricket umpires’ decisions are also influenced by expectations associated with batter skill.MethodsLBW decisions (n = 5578) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed in a multi-level binomial logistic regression paradigm. In our first model, we predicted the likelihood that an umpire will answer ‘out’ for batters in the top order (1–4), middle order (5–7), and low order (8-11). In our second model, we controlled for the correctness of a decision.ResultsUmpires were more likely to respond ‘out’ as the batting order progressed, however this did not appear to be due to biased decision-making. Instead, as batting order progressed, batters were more likely to actually be ‘out’.ConclusionsCricket umpires do not seem to be impacted by expectation bias associated with batting order. This study highlights the importance of controlling for the correctness of a decision when exploring bias in sport officials’ decisions.     

When in doubt,it’s not out: Match format is associated with differences in elite-level cricket umpires’ leg-before-wicket decisions

ObjectivesContextual factors can influence the way sports officials apply unambiguous rules. The aim of this study was to better understand the leg-before-wicket (LBW) decision-making behaviour of elite cricket umpires and determine whether their behaviour changes according to the format of the game in which they are adjudicating.MethodsLBW decisions (n = 5578) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed using a signal detection paradigm. Umpire sensitivity (A) and response bias (B) were compared to chance performance in three formats of the game: Four-day, One-day, and T20. Mixed effects models assessed sensitivity and response bias differences between match types.ResultsUmpires were able to differentiate between “out” and “not out” appeals to a high standard but were conservative and had a bias to respond “not out” in all formats of the game. Umpires were less accurate in the shorter formats of the game, particularly T20 cricket and were also significantly more conservative in T20 compared to Four-day Matches.ConclusionsCricket umpires are conservative and are highly accurate LBW decision makers. However, differences in their judgments were associated with different match formats. The unique task goals and contextual pressures afforded by the shorter formats of the game, particularly T20, may account for the observed performance differences we see here.     

Influence of win-loss ratio on performance,satisfaction and preference for opponents

Hypotheses about the preference for opponents in competitive situations, about performance under various win-loss ratios, and about task and opponent satisfaction under various win-loss ratios were tested. A 5 × 5 latin square with four replications and a repeated measure factor of trials was the design used with 20 female college students as subjects. The five different win percents were W₁₀, W₃₀, W₅₀, W₇₀, and W₉₀. A manipulative maze task was used with subjects receiving 20 trials against each of five confederate opponents. Results indicated that (a) when a person knows little or nothing about her ability level she initially prefers to compete with opponents of low ability but with each subsequent contest opponents of higher ability levels are preferred; (b) subjects performed better in the W₅₀ condition; (c) task satisfaction is higher when the percent of wins is equal to or greater than the percent of losses; and (d) opponent satisfaction is greater for opponents who perform equal to or better than the subject.     

Trash talking,respect for opponents and good competition

Trash talking, which is the North American term for verbal barbs directed at opponents during a sporting event in order to gain a competitive edge, is widely accepted by athletes and the athletic community as a legitimate part of sport. It is, however, morally indefensible. A simple Kantian injunction against treating opponents merely as objects to be overcome is sufficient to condemn this verbal abuse. Attempts to justify trash talking as a strategic ploy that implies no disrespect are disingenuous in view of the fact that its effectiveness depends on opponents' being offended by it. Nor can we defend trash talking as enhancing the goal of athletic competition, since the ability to verbally abuse opponents and remain impervious to their abuse are extraneous to the athletic excellence that contests are designed to measure. Attempts to deflect criticisms by partially immunizing sport from moral scrutiny are implausible. With few exceptions, we judge actions in sport by the same moral standards that we use in any other context. Moreover, the view that neither trash talking nor other actions in sport are fit subjects for strict moral scrutiny is inconsistent with the often-heard claim that sport promotes moral development.     

Power imbalance,its legitimacy,and aggression

Sixty Japanese female students were asked to exchange shocks in electric roulette games with female opponents. The subjects were assigned to either the 80%, 50%, or 20% win conditions. Half of them were then led to judge that the power unbalance was legitimate by being informed that the assignment was based on a prior performance contest, with the good performer being assigned to the advantageous position. The other subjects were led to perceive the power imbalance as illegitimate by being informed that the assignment was randomly decided. The opponents always severely attacked them. The retaliation by the subjects was analyzed by a two-way ANOVA with Power Imbalance and Legitimacy. It was found that the subjects both in the 20% and 50% win conditions set more intense shocks to their opponents than those in the 80% win condition. This is not consistent with the fear of retaliation hypothesis which had predicted that the subjects would refrain from intensely aggressing against the opponent who had a greater aggressive capacity. It was also found that in the 80% win condition, the subjects set more intense shocks when the unbalance had been determined by their performance than when determined by luck, whereas in the 20% win condition, they set more intense shocks when the imbalance had been determined by luck than when determined by their performance. These suggest that retaliation depended upon perceived justifiability of aggression which was predicated on the legitimacy of the power imbalance. Finding in the 50% win condition that the shock settings were higher when the power imbalance had been determined by their performance than when determined by luck was interpreted in terms of their heightened competitiveness.     

Effect of anosmia on the behavior of standard non-aggressive male mice opponents during agonistic encounters

This study assessed whether the differences observed in a previous experiment [Martinez M, Salvador A, Simon VM (1994): Aggressive Behavior 20:441–451] in the behavior of isolated male mice over several agonistic encounters in which they confronted either an “anosmic” or an “intact” non-aggressive “standard opponent” were due to the differences in the behavior of the opponents themselves. Ethologically-inspired analysis was used to assess the behavior of the opponents during the first agonistic encounter. Anosmic opponents spent less time in social investigation and defense and more time in immobility than intact ones. These results suggest that the differences in the behavior of the opponents could be one of the causes of the differences observed in the behavior of the aggressive males confronting them. However, more research is needed to study if other variables, such as the production of odors, are also affected by the state (deprived or intact) of the olfactory sense. These findings provide additional support for the view that the type of opponent used in studies on intermale aggression is of paramount importance.Aggr.

Behavioral changes over several successful agonistic encounters between male mice: Effects of type of “standard opponent”

This study assessed whether two types of non-aggressive “standard opponents” (“intact” and “anosmic” group-housed males) produced similar behavioral changes in isolated OF1 male mice given several experiences of victory. Experimental groups confronted either intact or anosmic opponents every two days until they had completed four encounters. The behavioral changes were recorded using a detailed ethologically inspired analysis. These changes were clearly different depending on the opponent type. When intact opponents were used, experimental subjects increased the time spent in digging, non-social exploration, explore from a distance, and attack over encounters, but showed decreased time spent in threat and a decreased latency to the first attack. In encounters with anosmic opponents, only declines in the latencies to threat and attack were noted. Moreover, the experimental groups differed in their behaviors over encounters. Those confronting intact opponents spent less time in social investigation, more time in explore from a distance and threat, and showed a shorter latencies to threat and attack than counterparts confronting anosmics. These results suggest that, although both types of “standard opponents” are similar in their non-aggressiveness, they elicit rather different behavioral responses in their adversaries. These findings provide additional support for the view that the type of opponent used in studies on intermale aggression is of paramount importance. Indeed, the use of different types of “standardized non-aggressive opponents” appears to be an important source of variability between studies. © 1994 Wiley-Liss, Inc.     

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.
