Gender-related differences in moral judgments

The moral sense is among the most complex aspects of the human mind. Despite substantial evidence confirming gender-related neurobiological and behavioral differences, and psychological research suggesting gender specificities in moral development, whether these differences arise from cultural effects or are innate remains unclear. In this study, we investigated the role of gender, education (general education and health education) and religious belief (Catholic and non-Catholic) on moral choices by testing 50 men and 50 women with a moral judgment task. Whereas we found no differences between the two genders in utilitarian responses to non-moral dilemmas and to impersonal moral dilemmas, men gave significantly more utilitarian answers to personal moral (PM) dilemmas (i.e., those courses of action whose endorsement involves highly emotional decisions). Cultural factors such as education and religion had no effect on performance in the moral judgment task. These findings suggest that the cognitive–emotional processes involved in evaluating PM dilemmas differ in men and in women, possibly reflecting differences in the underlying neural mechanisms. Gender-related determinants of moral behavior may partly explain gender differences in real-life involving power management, economic decision-making, leadership and possibly also aggressive and criminal behaviors.     

Ethnicity differences in child and parental outcomes following involvement the PACE program

This study investigated ethnic differences in the extent to which engagement (i.e., attendance and quality of participation) in the PACE (Parenting our Children to Excellence) program predicted positive child and parent outcomes. PACE is an 8-week preventive intervention aimed at parents of preschool children. The study investigated the relation of engagement to outcomes in an ethnically diverse sample of 298 African American and 280 European American parents. Overall results demonstrated that engagement in PACE significantly improved child and parent outcomes for both African American and European American participants. Some improvements were evident at post-assessment already and were maintained or became stronger at a one-year follow-up assessment, whereas others only became evident at follow-up. Specifically, results revealed that attendance in PACE significantly improved child coping competence and parenting stress for both the African American and European American samples. PACE attendance also significantly improved child behavior problems, parental satisfaction and parental efficacy for the European American sample. Findings indicate that PACE is a promising intervention for parents of African American and Caucasian preschoolers; although further research and program refinement is necessary in order to understand the mechanisms with the PACE intervention that seem to vary for African American compared to Caucasian families.     

Generating animal and tool names: an fMRI study of effective connectivity

The present fMRI study of semantic fluency for animal and tool names provides further evidence for category-specific brain activations, and reports task-related changes in effective connectivity among defined cerebral regions. Two partially segregated systems of functional integration were highlighted: the tool condition was associated with an enhancement of connectivity within left hemispheric regions, including the inferior prefrontal and premotor cortex, the inferior parietal lobule and the temporo-occipital junction; the animal condition was associated with greater coupling among left visual associative regions. These category-specific functional differences extend the evidence for anatomical specialization to lexical search tasks, and provide for the first time evidence of category-specific patterns of functional integration in word-retrieval.     

Grammatical class effects in brain-damaged patients: functional locus of noun and verb deficit

Two patients are described with grammatical class dissociation: CG, a semantic-dementia patient who presented a disproportionate impairment of nouns compared to verbs; SA, a patient with a left parietal lesion who presented impaired sentence production and a disproportionate deficit for verbs compared to nouns. The results are discussed within the current models on semantic memory and lexical access.     

Bidirectional Relationships Between Parenting Stress and Child Coping Competence: Findings From the Pace Study

The present study was designed to evaluate the bidirectional relationships between parenting stress and child coping competence. Data from a diverse sample of 610 parents enrolled in the parenting our children to excellence program was used to evaluate whether parenting stress negatively contributes to affective, achievement, and social coping competence in preschoolers, as well as whether child coping competence predicts parenting stress; after accounting for child disruptive behavior. Results from cross-lagged panel analyses demonstrated a bidirectional relationship, such that parenting stress predicted later child coping competence and child coping competence predicted later parenting stress. Assessment of ethnicity differences indicated that child coping continues to have a long-term impact on parenting stress, regardless of parent ethnicity. The same relationship did not hold for earlier parenting stress on later child coping competence, however, indicating a bidirectional relationship for African American families, but not for their European American counterparts. The relationship between parenting stress and child coping competence is discussed with respect to their conceptual and clinical implications. Suggestions for parent training intervention and prevention programs are given.     

A fMRI study of word retrieval in aphasia

The neural mechanisms underlying recovery of cognitive functions are incompletely understood. Aim of this study was to assess, using functional magnetic resonance (fMRI), the pattern of brain activity during covert word retrieval to letter and semantic cues in five aphasic patients after stroke, in order to assess the modifications of brain function which may be related to recovery. Four out of five patients had undergone language recovery, according to standard testing, after at least 6 months of rehabilitation. The cerebral activation of each patient was evaluated and compared with the activation pattern of normal controls studied with the same fMRI paradigm. In the patients, the pattern of brain activation was influenced by the site and extent of the lesion, by the degree of recovery of language, as reflected by task performance outside the scanner, and by task requirements. In the case of word retrieval to letter cues, a good performance was directly related to the activation in Broca's area, or in the right-sided homologue. On the other hand, in the case of semantic fluency, the relationship between performance level and activation was less clear-cut, because of extensive recruitment of frontal areas in patients with defective performance. These findings suggest that the performance in letter fluency is dependent on the integrity of the left inferior frontal cortex, with the participation of the homologous right hemispheric region when the left inferior frontal cortex is entirely of partially damaged. Semantic fluency, which engages the distributed network of semantic memory, is also associated with more extensive patterns of cerebral activation, which however appear to reflect retrieval effort rather than retrieval success.     

The breakdown of semantic knowledge: insights from a statistical model of meaning representation

Investigations of patients with semantic category-specific deficits have revealed a wide range of performance and variability in categories that are impaired or spared; this variability presents a challenge to accounts of category specificity. Accounts based only on impairment to semantic features of a particular type (e.g., visual), as well as accounts based only on featural properties (e.g., feature intercorrelations), are insufficient to explain the variability of patients' performance. A first goal of the paper is to discuss how a hybrid account incorporating both a level of organization according to feature types (a level of nonlinguistic conceptual representations) and a level of organization dictated by featural properties may provide a more comprehensive account of the cases reported in the literature. The second and most novel goal of the study reported here is to derive from our hybrid account a series of novel predictions concerning the representation and impairment of a different domain of knowledge: knowledge of actions and events, a domain of knowledge that has received remarkably little attention to date.
