A posteriori information effects on culpability judgments from a cross-cultural perspective

A posteriori information about the moral attributes of the victim of a crime can affect an observer's judgment on the culpability of the actor of the crime so that negative moral attributes of the victim will lead to a lower judgment of culpability. The authors found this effect of a posteriori information among 118 American and 123 Chinese participants, but the underlying mechanisms were different between the two cultural groups. The Americans considered the psychological state of the actor during the crime, whereas the Chinese considered the morality of the actor during the crime. The authors discussed these results in light of the respondents' implicit theories of morality.     

"The W and M are mixing me up": use of a visual code in verbal short-term memory tasks

When normal participants are presented with written verbal short-term memory tasks (e.g., remembering a set of letters for immediate spoken recall) there is evidence to suggest that the information is re-coded into phonological form. This paper presents a single case study of MJK whose reading follows the pattern of phonological dyslexia. In short-term memory tasks MJK does not phonologically re-code written materials but, it is argued, uses a visual code. There are three main lines of evidence for this, (a) MJK tends to substitute visually similar items for one another, (b) her performance is better with visual than auditory stimuli, and (c) she is able to remember numbers (e.g., 8) better than written words (e.g., eight). Investigation of short-term memory in others with phonological dyslexia is warranted.     

Concept mediation in trilingual translation: Evidence from response time and repetition priming patterns

Translation responses to individual words were elicited from 48 English-Spanish-French trilinguals, who translated in six directions at study and two directions at test. Patterns of translation response times and error rates at study reflected the relative proficiency of the trilinguals in comprehension and production of their three languages. At test, repeated items were translated more quickly than new items, with the strongest priming effects occurring for identical repetitions. Repetition priming was also substantial when only the stimulus language or only the response language matched from study to test, implying that repeated comprehension and production processes contribute to priming in translation. Patterns of response times and repetition priming indicate that translation in all directions involved conceptual access. Additive patterns in response time asymmetries and repetition priming were consistent with the treatment of word comprehension and production processes of translation as independent.     

Initial behavior outcomes for the peacebuilders universal school-based violence prevention program

PeaceBuilders is a universal, elementary-school-based violence prevention program that attempts to alter the climate of a school by teaching students and staff simple rules and activities aimed at improving child social competence and reducing aggressive behavior. Eight matched schools (N > 4,000 students in Grades K-5) were randomly assigned to either immediate postbaseline intervention (PBI) or to a delayed intervention 1 year later (PBD). Hierarchical linear modeling was used to analyze results from assessments in the fall and spring of 2 consecutive school years. In Year 1, significant gains in teacher-rated social competence for students in Grades K-2, in childself-reported peace-building behavior in Grades K-5, and reductions in aggressive behavior in Grades 3-5 were found for PBI but not PBD schools. Differential effects in Year 1 were also observed for aggression and prosocial behavior. Most effects were maintained in Year 2 for PBI schools, including increases in child prosocial behavior in Grades K-2. Implications for early universal school-based prevention and challenges related toevaluating large-scale prevention trials are discussed.     

The natural history of problem gambling from age 18 to 29

Aggregate-level prevalences and individual-level developmental trajectories of untreated problem gambling were examined in an 11-year, 4-wave longitudinal study spanning the adolescent through young adult years. The past-year prevalences, 3-4 year incidences, and lifetime prevalences of problem gambling from adolescence through young adulthood were relatively stable at 2%-3%, 1%-2%, and 3%-5%, respectively. Despite the stability of the prevalences at the aggregate level, problem gambling appeared to be more transitory and episodic than enduring and chronic at the individual level. The present study is consistent with the limited evidence available on the natural history of problem gambling in the community in suggesting that natural recovery may be the rule rather than the exception.     

First-order and second-order spectral 'motion' mechanisms in the human auditory system

Light energy displaced along the retinal photoreceptor array leads to a perception of visual motion. In audition, displacement of mechanical energy along the cochlear hair cell array is conceptually similar but leads to a perception of 'movement' in frequency space (spectral motion)--a rising or falling pitch. In vision there are other types of stimuli that also evoke a percept of motion but do not involve a displacement of energy across the photoreceptors (second-order stimuli). In this study, we used psychophysical methods to determine if such second-order stimuli also exist in audition, and if the resulting percept would rival that of first-order spectral motion. First-order auditory stimuli consisted of a frequency sweep of sixteen non-harmonic tones between 297 and 12123 Hz. Second-order stimuli consisted of the same tones, but with a random subset turned on at the beginning of a trial. During the trial, each tone in sequence randomly changed state (ON-to-OFF, or OFF-to-ON). Thus, state transitions created a 'sweep' having no net energy displacement correlated to the sweep direction. At relatively slow sweep speeds, subjects readily identified the sweep direction for both first-order and second-order stimuli, though accuracy decreased for second-order stimuli as the sweep speed increased. This latter characteristic is also true of some second-order visual stimuli. These results suggest a stronger parallelism between auditory and visual processing than previously appreciated.     

Group Identity and Conflicting Expectations of the Future in Northern Ireland

Much of the conflict in Northern Ireland is based on investments in one of three opposing political futures possible for the region: remaining part of Britain, joining Ireland, or becoming independent. Speculative scenarios describing each of these futures were randomly assigned to equal numbers of Protestant and Catholic undergraduates in Northern Ireland, and their expectations regarding material and civic improvement for their ingroup and peace and reconciliation between the groups were assessed. Two dimensions of religious identity, measured by the Identity and Public subscales of Luhtanen and Crocker's (1992) Collective Self-Esteem Scale (CSES), moderated the differences between groups, but only for their expectations of peace and reconciliation. Stronger expectations of improvement for the ingroup were related to higher scores on the Public subscale, regardless of religion or the political future presented. Thus, group identity had a complex, context-dependent relationship to intergroup conflict.     

Anger-Related Traits and Response to Interpersonal Conflict Among New York City Traffic Agents1

This study evaluates the psychosocial correlates of anger-related traits. Participants include New York City traffic enforcement agents (TEAs), who issue summonses for vehicular and parking violations and are frequently confronted by angry motorists. This sample of TEAs is 53% African American and 57% female. Participants completed surveys at 2 points, 4 months apart, which measured attitudinal, affective, and expressive components of hostility and anger, as well as dimensions of workplace psychosocial response. Results indicate that trait anger-in was positively associated with frequency of conflict, anger intensity, and burnout in cross-sectional analyses; and positively associated with frequency of conflict in prospective analyses. Trait anger was positively associated with an increase in burnout over a 4-month period. These findings provide support for the transactional model of hostility and health and have implications for worksite interventions promoting cardiovascular health.     

Herrnstein''s syllogism: genetic and shared environmental influences on IQ, education, and income

Genotypes may influence the phenotypic associations among IQ, education, and income. To investigate this hypothesis, we believe that the appropriate methodology requires estimation of genetic and environmental influences using data able to separate these influences. The National Longitudinal Survey of Youth (NLSY) is a nationally representative sample that contains genetically-informative full- and half-siblings (28–35 years old in 1992; Ns=1943 full-siblings, 129 half-siblings). A biometric genetic model was fit that estimated the shared environmental and genetic variance components of IQ, years of education, and hourly income. The total heritabilities were 0.64 for IQ, 0.68 for education, and 0.42 for income. Heritabilities due to a common genetic factor were 0.35 for IQ, 0.52 for education, and 0.12 for income. Environmental influences due to a common shared environmental factor were 0.23 for IQ, 0.18 for education, and 0.08 for income. The model predicted a correlation of 0.63 between IQ and education and 0.34 between IQ and income. Sixty-eight percent of the former and 59% of the latter was genetically mediated; the remainder was mediated by common shared environment. These findings suggest that social inequality in the United States has its origin in both genetically-based traits and in different environmental backgrounds.     

Can Perceivers Identify Likelihood to Sexually Harass?

We investigated how men who differ in theirlikelihood to sexually harass (LSH) are perceived bythemselves and others. In Study 1, 36 Caucasian maleparticipants, who were paid for their participation, were videotaped being interviewed by asubordinate female. Participants rated her performanceand then responded to self-report attitudinal andpersonality scales. Higher LSH men reported moretraditional attitudes toward women's roles, a less femininepersonality, and lower competency ratings for the femaleinterviewer. Study 2 investigated whether participantscould differentiate between high and low LSH men from videoclips. Eighty-one male and 76female Caucasian participants, who were fulfilling acourse requirement, rated high LSH men (compared to lowLSH men) as (1) higher in LSH, (2) more masculine, (3) less feminine, and (4) more traditionaltoward women's roles than low LSH men. Implications ofthis ability to detect likelihood to sexually harass arediscussed.
