Motor impairment and antisocial behavior in adolescent males at high risk for schizophrenia

A familial link between schizophrenia and antisocial behavior has been established (e.g., Silverton, 1985). This study examined this relationship in a Danish cohort. The subjects were 36 high-risk males (offspring of a schizzophrenic parent) and 36 low-risk males (offspring of parents without psychopathology). This high-risk subjects exhibited more antisocial behavior than the low-risk subjects. We tested the hypothesis of a correlation between neurointegrative deficits, as defined by motor impairment, and antisocial behavior, rated at ages 10–13, in subjects at genetic risk for schizophrenia. Path analyses were conducted from motor impairment at 1 year and motor impairment at 10–13 years to antisocial behavior separately for high-risk and low-risk subjects. Adolescent motor impairment was a significant predictor of antisocial behavior for high-risk subjects. Motor impairment at 1 year was also associated with antisocial behavior for these subjects, although the association was partly due to the indirect effects of motor impairment at 1 year on motor impairment at 10–13 years, which, in turn, was associated with changes in antisocial behavior. As predicted, none of the path coefficients nor the effect coefficient was significant for low-risk subjects.     

Barriers to fair housing for black women

This article examines barriers to fair housing (or equality of access to housing opportunities) for black women in both the private and public sectors. First the coverages of federal fair housing legislation are described. Then evidence of discrimination (behavior that denies to one group the rights or opportunities given to others) against black women seeking housing is explored in several contexts—on the basis of race, of sex, and of membership in a family with children. Available data suggest that the major form of housing market discrimination confronting black women is based on race. Despite legislation prohibiting them, subtle forms of discrimination on the basis of both race and sex appear to continue. In addition, several instances were reported in which discrimination against families with children was used to camouflage racially motivated discrimination.This analysis is the author's own and should not be attributed to the U.S. Congressional Budget Office.     

The role of recall time in producing hypermnesia

In two experiments subjects presented with either words or pictures showed improved recall over three successive recall tests for both types of materials, partially replicating Erdelyi’s finding of hypermnesia. However, these subjects did not recall more unique items than other subjects who received only one test equated in time with the three shorter ones. It is concluded that hypermnesia results from simply allowing subjects additional recall time. In a third experiment subjects were shown to recall additional information even after a long recall period employed during an experimental session. This surprising amount of item recovery during long recall periods is attributed to the use of subjective retrieval cues that are thought to function in a manner analogous to externally manipulated cues.     

Analogical encoding facilitates knowledge transfer in negotiation

Information learned in one situation often fails to transfer to a similarly structured situation. However, prior findings suggest that comparing two or more instances that embody the same principle can promote abstraction of a schema that can be transferred to new situations. In two lines of research, we examined the effects of analogical encoding on knowledge transfer in negotiation situations. In Experiment 1, undergraduates were more likely to propose optimal negotiation strategies and less likely to propose compromises (a suboptimal strategy) when they received analogy training. In Experiment 2, graduate management students who drew an analogy from two cases were nearly three times more likely to incorporate the strategy from the training cases into their negotiations than were students given the same cases separately. For both novices and experienced participants, the comparison process can be an efficient means of abstracting principles for later application.     

Characteristics of incarcerated women's participation in groups: Exploring the Programme for the International Assessment of Adult Competencies United States prison dataset

This study employs logistic regression and latent class analyses to explore the relationship between incarcerated women's (n = 252) participation in nonacademic prison groups/skills classes and their demographic (e.g., education) and prison context (e.g., time to release) characteristics, using the 2014 Programme for the International Assessment of Adult Competencies United States prison dataset. Time to release was a significant factor in readiness class participation. Time to release and race/ethnicity were significant factors in addiction group participation. Education level had the largest effect size across all groups/classes explored. We discuss counseling implications for using group/class screening to connect with incarcerated women, especially those with intersecting and historically marginalized identities.     

Sensory modality and stimulus control in the pigeon: Cross-species generality of single-incentive selective-association effects

In earlier studies with rats, the effectiveness of the auditory element of a tone–light discriminative stimulus was enhanced when the conditioned incentive value of the compound was negative rather than positive. The present experiment systematically replicated these results in pigeons trained to press a treadle in the presence of a tone–light compound under food-reinforcement or shock-avoidance schedules. Positive incentive value was conditioned to the compound by associating it with either food or relative safety from shock. The compound was made negative in other groups by associating it with shock or the absence of food. When tone and light were presented separately following this training, control by the auditory element was significantly enhanced in the conditions designed to make the compound negative rather than positive. The similarity of this constraint on learning in rats and pigeons suggests that it involves a fundamental attentional and incentive-motivational process with widespread species generality.
