冷酷无情特质：一种易于暴力犯罪的人格倾向

冷酷无情特质(callous unemotional trait, CU)是指对他人冷漠、缺乏罪责感、低共情的一种人格倾向, 伴随有高频率和高破坏性的反社会行为甚至暴力犯罪。CU特质者在情感上表现为对负性情绪加工不敏感, 缺乏共情; 在认知上表现出追求奖赏、忽视惩罚; 在生物学方面, CU特质者生理唤醒水平低、皮质醇水平低、杏仁核和腹内侧前额叶活动异常。未来研究的方向是修订发展本土化CU特质量表、探析CU特质者的性别差异、梳理CU与品行障碍等其他精神障碍的关系、为暴力犯循证矫正的方案设计提供科学依据。     

Consistency of aggressive temperament in domestic pigs: The effects of social experience and social disruption

Resident‐intruder (R‐I) tests can be used to measure the aggressive temperament of domestic pigs (Sus scrofa), and have previously been shown to predict the severity and persistence of aggression when unfamiliar pigs are mixed. To study the consistency of individual differences in aggressiveness over time, 112 pigs (eight from each of fourteen litters) were given two R‐I tests at each of three ages (46, 80, and 113 days). Pigs were R‐I tested singly in an arena within the home pen, where a smaller unfamiliar intruder pig was introduced to a resident pig. Latency to the first attack by the resident was recorded, and the test was stopped as soon as an attack occurred, otherwise the test lasted five minutes. Pigs from eight of the litters used here had been allowed to mix with another litter prior to weaning (days 10–30; socialised), while pigs in six litters remained in littermate groups (control). To determine whether consistency would survive the effects of social disruption, pigs were mixed into new groups on two occasions between the first and second test, then remained in these groups until the third test. Evidence of consistency was found, despite the social disruption. Socialised pigs were more aggressive than controls, females were more aggressive than males, and certain litters were more aggressive than others. After adjusting for these, consistent differences between individuals were still evident. Consistency was higher between the second and third tests compared to the first and second, possibly because of stable group membership or the effects of age or experience. In support of the idea that social experience improves consistency, socialised pigs were more consistent than controls throughout. Evidence of consistent individual differences in aggressive temperament suggests that breeding or changes to early life experiences could have a long‐lasting influence on aggressive behaviour in pigs.

工读学生与普通学生对责任判断的比较研究

用内隐联想测验对40名工读学生与普通学生的责任判断进行比较研究,结果表明:工读学生比普通学生辨别攻击词以及与"责任在他"有关的短语的反应时短;工读学生辨别与"责任在他"有关的短语的速度比辨别与"责任在我"有关的短语的速度快,而普通学生辨别与"责任在他"有关的短语的速度比辨别与"责任在我"有关的短语的速度要慢;工读学生在"责任在他—攻击,责任在我-不攻击"的联合辨别反应时上比普通学生短。这些反应时的差异反映了工读学生存在着敌意归因与对攻击信念的内隐联想。

The moderating effect of parental warmth on the association between spanking and child aggression: a longitudinal approach

Using data from the Early Head Start Research and Evaluation Study, this study analysed the stability of child aggressive behaviour beginning in infancy and tested whether spanking when the child was 36 months was associated with aggressive child behaviour among three ethnic groups and whether maternal warmth moderated the effect of spanking on aggressive behaviour in each ethnic group at 36 months, after controlling for earlier aggressive behaviour. Participants included 693 Hispanic parent–child dyads, 1013 African‐American dyads and 1086 Caucasian dyads who met qualifications for participation in the Early Head Start programme. Findings suggest that infant temperament was associated with aggressive behaviour at 24 and 36 months and that child aggression remained stable. Among the three ethnic groups, spanking was only associated with aggressive behaviour for children who had Caucasian mothers and maternal warmth did not moderate the effect of spanking on aggressive behaviour.

Behaviour of Young Growing Pigs in a Resident‐Intruder Test Designed to Measure Aggressiveness

A total of 125 growing pigs (47 days old) were tested for aggressive responses on two occasions using a resident‐intruder (R‐I) design. Our aims were twofold: (1) to attempt to replicate earlier work on pigs showing that resident aggression is a consistent individual characteristic, unaffected by weight or sex of the resident or intruder and (2) to develop behavioural measures to characterise the wide range of aggressive responses in the test. Resident pigs, housed since birth with littermates, were placed individually in a divided‐off portion of their home pen, and a smaller, unfamiliar intruder (approximately 66% of the resident's weight) was introduced. The test ended 5 min after the first investigation of the intruder by the resident or when one of the pigs began to attack the other (by delivering a sudden, rapid series of bites). On days 1 and 2, 33.6% and 43.2% of tests, respectively, ended in an attack by a resident. Intruder attacks were rare. Pigs were consistent in whether they attacked or not over the two tests, although attack latencies for pigs attacking in both tests were not correlated. Females were more likely to attack and attacked more quickly than males on the first test day but not in the second test or overall. Intruder sex had some effect on the test outcome (males were attacked more rapidly in the second test only). Resident and intruder weight had no effect. Aggressive pigs (meaning pigs that attacked vs. pigs that did not and fast‐attacking pigs vs. slow‐attacking pigs) showed a number of differences in behaviour during the R‐I test: (1) they took longer to make initial contact with the intruder in their first test; (2) they showed a higher frequency of aggressive acts (single head knocks, bites, and shoves); (3) they spent a greater proportion of the test engaging in social contact with the intruder rather than non‐social behaviours; (4) their social behaviour involved more postures directed toward the head as opposed to flank‐ or rear‐directed postures or re‐establishing social contact; and (5) they showed closer physical contact with intruders during social encounters, as characterised by their lower head positions. Some of these behavioural measures could be used to improve the measuring power of the test in the future. Improved behavioural measures would enable aggressiveness scoring among pigs that did not attack instead of classifying them all together as “non‐attacking.” Aggr.

The effects of alcohol and the salience of aggressive cues on triggered displaced aggression

Alcohol increases the aggression-augmenting effects of provocation. Theories of alcohol and aggression suggest that impaired cognitive processing induced by acute intoxication leads individuals to process aggression-inducing social cues differently depending on whether they are high or low in salience. We examined the effects of intoxication and aggressive cue salience within the triggered displaced aggression paradigm. An ethnically diverse sample of 74 primarily young adult participants (40 men and 34 women; M=23.28, SD=3.14 years) were recruited from the university community and surrounding area. All participants were provoked by an experimenter, randomly assigned to a 2 (alcohol condition: alcohol vs. placebo) x 2 (trigger salience: high vs. low salience) between-subjects design, and then given the opportunity to aggress against the undeserving triggering agent. As expected, intoxication combined with a salient triggering cue elicited the most displaced aggression among all conditions. These results provide the first evidence that the effect of alcohol on triggered displaced aggression is moderated by the salience of the triggering event.

Weakly aggressive behaviour towards nymphs in the cockroach Schultesia nitor (Blattaria: Zetoborinae)

This paper describes aggressive behaviour in the cockroach Schultesia nitor, a tropical forest species living in bird nests. Young S. nitor nymphs are known to show active dispersal while old nymphs and adults are contrastingly strongly gregarious, a combination of features never observed in other cockroach species. Our laboratory experiments using video recording of confrontations between pairs show that aggressive behaviour towards conspecific nymphs is not exhibited towards nymphs of the species Phoetalia pallida, and thus can be considered species specific in S. nitor. But, it is not kin oriented: the mother and all adults of both sexes in different physiological states exhibit this behaviour as well. Six types of aggressive interactions were discriminated, occurring in age-symmetric pairs of nymphs and adults. Even more frequent aggression was exhibited by adults and last instar nymphs towards younger nymphs of all instars. The frequency of aggressive acts and types of aggressive interactions varied according to sex and size of the two interacting individuals. The possible function and evolution of this behaviour is discussed, with emphasis on the difficulty of interpreting obvious but weak and not kin-biased aggression.
