Reaffirming the poverty of the stimulus argument: a reply to the replies

Lidz, Waxman, and Freedman [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn’t have learned: Evidence for syntactic structure at 18-months. Cognition, 89, B65-B73.] argue that acquisition of the syntactic and semantic properties of anaphoric one in English relies on innate knowledge within the learner. Several commentaries have now been published questioning this finding. We defend the original finding by identifying both empirical and logical flaws in the critiques.     

Paternal Psychiatric Symptoms and Maladaptive Paternal Behavior in the Home During the Child Rearing Years

Data from the Children in the Community Study, a community-based longitudinal study were used to investigate associations between paternal psychiatric disorders and child-rearing behaviors. Paternal psychiatric symptoms and behavior in the home were assessed among 782 families during the childhood and adolescence of the offspring. Paternal anxiety, disruptive, mood, personality, and substance use disorders were independently associated with specific types of maladaptive paternal behavior in the home during the child-rearing years after paternal age, education, income, co-occurring paternal psychiatric symptoms, offspring age, sex, intelligence, temperament, and psychiatric symptoms were controlled statistically. Paternal psychiatric disorders that were present by mean offspring age 14 were associated with elevated risk for maladaptive paternal behavior in the home at mean age offspring 16, after prior maladaptive paternal behavior was controlled statistically. These findings suggest that paternal psychiatric disorder may be an important determinant of maladaptive paternal behavior in the home during the child-rearing years. Improved recognition and treatment of paternal psychiatric disorders may help to reduce the amount of maladaptive parenting behavior that many children and adolescents might otherwise be likely to experience.     

Event-based plausibility immediately influences on-line language comprehension

In some theories of sentence comprehension, linguistically relevant lexical knowledge, such as selectional restrictions, is privileged in terms of the time-course of its access and influence. We examined whether event knowledge computed by combining multiple concepts can rapidly influence language understanding even in the absence of selectional restriction violations. Specifically, we investigated whether instruments can combine with actions to influence comprehension of ensuing patients of (as in Rayner, Warren, Juhuasz, & Liversedge, 2004; Warren & McConnell, 2007). Instrument-verb-patient triplets were created in a norming study designed to tap directly into event knowledge. In self-paced reading (Experiment 1), participants were faster to read patient nouns, such as hair, when they were typical of the instrument-action pair (Donna used the shampoo to wash vs. the hose to wash). Experiment 2 showed that these results were not due to direct instrument-patient relations. Experiment 3 replicated Experiment 1 using eyetracking, with effects of event typicality observed in first fixation and gaze durations on the patient noun. This research demonstrates that conceptual event-based expectations are computed and used rapidly and dynamically during on-line language comprehension. We discuss relationships among plausibility and predictability, as well as their implications. We conclude that selectional restrictions may be best considered as event-based conceptual knowledge rather than lexical-grammatical knowledge.     

When can an object feel heavier than itself? Perceived heaviness of a wielded object depends on grasp position

Perceived heaviness is a function of how an object resists being moved, and such resistance is determined by object mass and the distribution of that mass relative to the wrist. Whereas mass is independent of grasp position on an object, distribution of mass relative to the wrist is not. Therefore, perceived heaviness should vary with grasp position. Blindfolded participants wielded internally weighted cylindrical objects while grasping them at different distances from the centre of mass. They rated how heavy each object felt at each location relative to a standard object. The results show that objects felt heavier as they were grasped farther from the centre of mass, highlighting the role of the touch system in controlling movement.     

Perspectives on dichotic listening and the corpus callosum

The present review summarizes historic and recent research which has investigated the role of the corpus callosum in dichotic processing within the context of audiology. Examination of performance by certain clinical groups, including split brain patients, multiple sclerosis cases, and other types of neurological lesions is included. Maturational, age related, and genetic factors are also discussed. Finally, some attention is given to recent trends in audiology research to develop improved diagnostic and rehabilitation tools for individuals with dichotic deficits potentially related to callosal dysfunction.     

Mental illness, criminal risk factors and parole release decisions

Research has not examined whether higher rates of parole denial among inmates with mental illness (MI) are the result of the increased presence of criminal risk factors among this population. Employing a representative sample of inmates with (n = 219) and without (n = 184) MI receiving parole release decisions in 2007, this study tested whether the central eight risk factors for recidivism considered in parole release decisions intervened in the relationship between MI and parole release. MI was associated with possession of a substance use disorder, antisocial personality disorder and violent charges while incarcerated; however, these factors were not related to release decisions. MI was found to have neither a direct nor an indirect effect on release decisions. While results indicate that release decisions appear, to some extent, to be evidence-based, they also suggest considerable discretion is being implemented by parole board members in release decisions above and beyond consideration of criminal risk factors.     

Imagining the unthinkable, illuminating the present

During a catastrophe that disables the health system, ethically charged situations will undoubtedly emerge that will challenge patients, relatives, clinicians, and others involved in health delivery. This second of two special sections of The Journal of Clinical Ethics includes discussions of the implications of a system collapse on particularly vulnerable member of society, children, pregnant women, and those who are socio-economically, culturally, and linguistically disempowered. Additionally, it offers insights into the processes used by committees to plan for catastrophic care.     

Exemplary cases in clinical ethics: commentary on the case of Mr. A

A commentary on a case of a man who is left a "high quad" (ventilator dependant as well as quadriplegic) after an accident discusses the following: The right of patients who sustain catastrophic injuries to choose to discontinue life-sustaining treatment, The role of capacity assessment in treatment decisions and in ethics consultations, The role of advance directives (ADs) for such patients if they lack capacity, Whether a do-not-resuscitate or do-not-attempt-resuscitation order should be seen as "a medical order" or an advance directive, Some hints about what might be intended when a patient refers to the criterion of having a "meaningful life."     

Predictive and incremental validity of the Violence Risk Appraisal Guide scores with male and female jail inmates

The present study examines the predictive and incremental validity of Violence Risk Appraisal Guide scores in a sample of 328 male and 145 female jail inmates held on felony charges. Significant gender differences were observed in VRAG item and total score means, as well as in correlations between the VRAG and concurrent measures of aggression. VRAG scores significantly predicted institutional misconduct during incarceration and recidivism in the first year postrelease for male inmates but not for female inmates. In terms of incremental validity, VRAG scores predicted institutional misconduct and recidivism beyond that accounted for by psychopathy for male inmates but not for female inmates. Implications for clinical practice and future research are discussed.     

Job level, demands, and resources as antecedents of work–family conflict

Although substantial research has examined the conflict that employees experience between their work and family roles, the literature has not investigated the prevalence and antecedents of work–family conflict for individuals who work at different levels of an organization. This study examines differences in work–family conflict (work interference with family and family interference with work) for lower-level and higher-level employees, the factors that might explain these differences, and the differential effect of resources on conflict across job levels. Results indicate that higher-level workers experience greater conflict in both directions than lower-level workers, and that work- and home-based resources are differentially related to the conflict experienced by employees who hold lower-level and higher-level jobs.
