Psychopathy and aggressive behaviour among Nigerian male prison inmates: The moderating role of substance abuse

This study investigated the moderating role of substance abuse in the relationship between psychopathy and aggression among male prison inmates. Two hundred and sixty-seven male prison inmates from the Nigerian Prison Services were participants. The inmates were incarcerated for armed robbery (27.3%), theft (31.1%), murder (12.8%), rape/assault/child abuse (19.1%), burglary/arson (5.6%) and kidnapping (1.5%) in Enugu prisons, Nigeria. Their mean age was 28.32; SD = 5.53. Their length of time in prison ranges from 1 to 12 years, with a mean of 3.38 years. Participants responded to self-reported measures of aggression, psychopathy, and drug abuse. The result of the moderated regression analysis indicated substance abuse to moderate the relationship between primary psychopathy and verbal aggression, and between secondary psychopathy and hostility. The study findings underscore the importance of psychological intervention aimed at addressing aggression among prison inmates with histories of substance abuse and psychopathy.     

SUSTAINABILITY SEEN THROUGH AN INTEGRAL LENS

The call to create a sustainable society includes many ideas that are consonant with Integral Science, including its conception of humans as part of nature, emphasis on healthy communities as fundamental building blocks, and emphasis on collaborative social organization. Integral Science expands the sustainability discussion by adding an ecological view of growth, and fractal structures to explain resilient structure. It describes the new society as a collaborative learning society that adapts appropriately to accurate signals. It also shows that the new society is already emerging.     

Executive function and theory of mind: stability and prediction from ages 2 to 3

Several studies have demonstrated a relation between executive functioning (EF) and theory of mind (ToM) in preschoolers, yet the developmental course of this relation remains unknown. Longitudinal stability and EF-ToM relations were examined in 81 children at 24 and 39 months. At Time 1, EF was unrelated to behavioral measures of ToM but was significantly related to parent report of children's internal-state language, independent of vocabulary size. At Time 2, behavioral batteries of EF and ToM were significantly related (r=.50, p<.01). Furthermore, EF (Time 1) significantly predicted ToM (Time 2), independent of several controls. A reciprocal relation (internal-state language --> EF at Time 2) was nonsignificant with the controls included. Individual differences in EF were relatively stable.     

In focus. Has patient autonomy gone to far? Geneticists' views in 36 nations

We surveyed genetics professionals, patients, and the public about rights to information, to requested services, and to parenthood, posing difficult cases found in practice. In all, 2906 genetics professionals (63%), 499 primary care physicians (59%), 476 North American genetics patients (67%), 394 French patients (51%), 593 German patients (65%), and 988 members of the American public (99%) returned anonymous questionnaires. Results suggest a trend toward increased respect for patient autonomy since an earlier survey in 1985; in most nations more would perform prenatal diagnosis for a couple with 4 daughters who desire a son. A minority (35% in U.S., 14% elsewhere) would perform PND for a deaf couple who want a deaf child, but most (94% in U.S., 62% elsewhere) would do prenatal paternity testing in the absence of rape or incest. About half (51%) would support a woman with fragile X who wants children. The trend to respect patient autonomy was greatest in the U.S. and was least evident in China and India. In general, responses to these cases illustrate a shift away from population or eugenic concerns to a model of genetics focused on the individual.     

Factor analytic evaluation of differences between black and caucasian emotionally disturbed children on the children's depression inventory

Scores on the Children's Depression Inventory (CDI) for 392 Caucasian and 159 black psychiatric inpatients between 6 and 18 years of age were subjected to principal-components factor extraction with Varimax rotation. Factors not contributing to variance were eliminated using the scree test (Cattell, 1966) and the degree of variance accounted for by remaining factors for both groups was examined through respective squared multiple correlations. A comparison of CDI factors for blacks and Caucasians indicated some differences, with blacks be ing less suicidal yet higher on other behavioral dimensions, such as oppositionality, and Caucasians higher on affective dimensions, such as sadness. The results support research on black-Caucasian differences and suggest the need to validate further the CDI with minority populations.     

Third-Party Consent Searches: Legal vs. Social Perceptions of “Common Authority”1

We investigate the degree of correspondence between legal concepts underpinning third-party consent searches (a co-resident permits police search of shared living space and belongings) and laypersons' sociocultural expectations. In accord with the legal concepts, we hypothesized that laypersons would be able to distinguish between authority over (1) exclusive-use vs. common-use areas, and (2) personal effects in exclusive-use vs. common-use areas. But, we also expected that (3) the interpretation of “common authority” would be influenced by the presence vs. absence of the co-resident, and (4) the type of intruder (social, commercial, civil authority, or criminal justice authority) would influence responses to requests for entry. These hypotheses were tested using a fully between-subjects, factorial design (N= 160). Results supported our first three hypotheses. Subjects understood the concept of a warrantless search and distinguished between “exclusive use” areas and “common authority” areas at the level of rooms within the shared residence. Subjects' interpretation of “common authority” for third-party consent purposes was influenced by physical presence of the co-resident. If the co-resident was absent, “common authority” was interpreted as independent consent power. There was no consensual interpretation of “common authority” when the co-resident was present and protested the proposed search. Results suggest situational dependence of lay understandings of “common authority” over jointly used areas.     

Perceived Voluntariness of Consent to Warrantless Police Searches1

Two issues involved in warrantless consent searches were examined: perceived voluntariness of consent and affirmativeness, or the form of a police search request. Research on actor-observer divergence in causal perceptions suggests the possibility of misunderstandings between courts and defendants concerning perceived voluntariness of consent to warrantless searches. Research on speech-act theory suggests that perceived choice of consent would be greatest when a search request was phrased interrogatively and unspecifically. In a laboratory experimental investigation of these legal issues, 96 subjects read vignettes in which two levels of perspective (consentor or observer) were crossed with two levels of request form (interrogative or declarative) and two levels of request specificity (not specific or specific). Observers underestimated the likelihood of consentors' requesting more information about the search request and overestimated consentors' perceived freedom to revoke consent and the permitted scope of the search. Search requests phrased interrogatively resulted in higher perceived choice in permitting entry, but also resulted in higher perceived likelihood of actually granting entry. Ignorance of legal ramifications of consent searches appears to be widespread, even in a college-educated sample.     

Another look at gender-related differences in leadership behavior

This investigation examined self-related behavioral differences in terms of broad leadership styles using a methodology that minimized biases inherent in research designs previously employed to investigate this area. Subjects consisted of 40 males and 41 females who served in the role of leader, and who instructed both a male and a female subordinate in a card-sorting task. Experimental sessions were tape-recorded and transcribed, after which judges classified word phrases into various language categories. Factor analysis of the language categories yielded two factors of verbal behavior within a leadership situation: a socially oriented style and a task-oriented style. In contrast to generally accepted stereotypes, results indicated that within the present experimental context male leaders preferred to use phrases that indicated a more social style than female leaders. However, both male and female leaders used language that indicated a task-oriented approach to a significantly greater degree when instructing a female rather than a male subordinate. Implications and interpretations of the results are discussed.     

The Impact of Case Characteristics and Prior Jury Experience on Jury Verdicts1

An archival analysis of records from 206 criminal cases was used to evaluate the impact of personal and situational factors on jury verdicts. In particular, we evaluated whether repeated jury service produced bias in jurors that was sufficient to affect jury decisions. A variety of case characteristics and indices of prior jury experience was examined for their relative impact on trial outcomes. Several of the case characteristics were related to verdicts, but the personal characteristics were not. Although more than half of the juries contained experienced jurors, juror experience had little influence on verdicts in either major or subsidiary analyses. However, there was a slight tendency for small juries with large proportions of experienced jurors to convict. This result is consistent with data from Kentucky; a meta-analysis across the two data sets indicates that it is a reliable finding. The results have implications for the determination of jury size. We suggest that future research examine the possibility that increasing jury size may reduce the influence of an individual's bias by providing a balance of other jurors with no or offsetting biases.
