Mental health of lesbian, gay, bisexual, and heterosexual siblings: effects of gender, sexual orientation, and family

Self-identified lesbian, gay male, and bisexual (LGB) individuals were recruited via convenience sampling, and they in turn recruited their siblings (79% heterosexual, 19% LGB). The resulting sample of 533 heterosexual, 558 lesbian or gay male, and 163 bisexual participants was compared on mental health variables and their use of mental health services. Multilevel modeling analyses revealed that sexual orientation predicted suicidal ideation, suicide attempts, self-injurious behavior, use of psychotherapy, and use of psychiatric medications over and above the effects of family adjustment. Sexual orientation was unrelated to current psychological distress, psychiatric hospitalizations, and self-esteem. This is the 1st study to model family effects on the mental health of LGB participants and their siblings.     

Space is special in Sign

Following groundbreaking work by linguists and cognitive scientists over the past thirty years, it is now generally accepted that sign languages of the deaf, such as ASL (American Sign Language) or BSL (British Sign Language), are structured and processed in a similar manner to spoken languages. The one striking difference is that they operate in a wholly non-auditory, visuospatial medium. How does the medium impact on language processing itself?     

Using event-related potentials to examine hemispheric differences in semantic processing

Event-related potentials (ERPs) were used as the dependent measure in a divided visual field study examining the processing of lexically ambiguous words in the cerebral hemispheres. The goal was to determine if the N400 ERP component is sensitive measure of hemispheric differences in semantic processing. ERP waveforms were examined for lateralized target words that were related to either the dominant (MONEY) or subordinate (RIVER) meanings of ambiguous words (BANK). These waveforms were compared to trials where the prime-target pairs were unrelated. Reliable N400s, reflecting a significant difference between related and unrelated trials, were seen when targets were presented to the right visual field/left hemisphere. However, there were no N400s observed for either the dominant or subordinate conditions when targets were presented to the left visual field/right hemisphere.     

The impact of a history of sexual abuse on high-risk sexual behaviors among females attending alternative schools

The goal of this study was to explore whether a history of sexual abuse is associated with high-risk sexual behaviors among female adolescents attending alternative schools in a large urban city in the southwestern United States, and to examine the role of depression and substance abuse in explaining this association. One hundred eighty-four sexually active female adolescents constituted the sample for this analysis. Forty-nine (26.6%) reported that they were forced to have sex. Having a history of sexual abuse substantially increased sexual risk behaviors. Adolescents reporting a history of sexual abuse, compared to those who did not report such a history, were significantly more likely to have initiated sexual activity (intercourse) before age 14, to have had three or more sexual partners in the last 3 months, and to have had a history of sexually transmitted diseases. These associations remained significant after controlling for age, ethnicity, and family income. Depression and substance abuse did not explain the association between sexual abuse and high-risk sexual behaviors. It seems reasonable to conclude that adolescents with a history of sexual abuse have greater difficulty practicing safe sexual behaviors than do those who have not been sexually abused. Given the prevalence of child sexual abuse and the extent of its impact, it is critical that intervention strategies for adolescent females address the issue of abuse and help them adopt self-protective sexual behaviors. The findings also highlight the importance of targeting adolescents who attend alternative schools.     

Stability of formal thought disorder and referential communication disturbances in schizophrenia

This study examined the degree to which different types of communication disturbances in the speech of 48 schizophrenia patients and 28 controls were variable and state related versus stable and traitlike. Clinically rated formal thought disorder and 5 types of referential disturbance showed substantial stability within participants over time. The sixth type of referential disturbance, the vague reference, was not stable over time. Formal thought disorder was associated with the severity of core psychotic symptoms in patients. whereas referential disturbances showed little or no association with positive or negative symptom severity. Furthermore, changes in psychotic symptoms over time were accompanied by corresponding changes in formal thought disorder but not referential disturbances. These results support the idea that some types of referential disturbances are traitlike and may be reflective of vulnerability as well as manifest illness.     

Toddlers' self-regulated compliance to mothers,caregivers, and fathers: implications for theories of socialization

To compare children's socialized behavior to parents and nonparental agents, this study examined self-regulated compliance to mothers and caregivers--an early form of internalization--in 90 toddlers, half of whom were also observed with fathers. Adults were observed in play, teaching, and discipline sessions with the child and were interviewed on child-rearing philosophies. Child cognition and emotion regulation were assessed, and naturalistic observations were conducted at child-care locations. Mean-level and rank-order stability were found in child compliance to the 3 adults. Child emotion regulation and adult warm control in a discipline situation were related to self-regulated compliance to the mother, caregiver, and father. Compliance to parents correlated with parental sensitivity and philosophies, and compliance to the caregiver correlated with child cognition and social involvement when child-care quality was controlled. Maternal sensitivity and warm control discipline predicted compliance to the caregiver but not vice versa. Results are consistent with theoretical positions on the generalization of socialization from the mother to nonmaternal agents.     

‘Implanted in us by Nature’: The Cognitive Science of Religion and its Importance for Theology

Abstract: The Cognitive Science of Religion (CSR) holds that religion emerges from human cognition and its intuitions. Hence, it describes religion as a ‘natural’ belief in ‘supernatural agents’. Traditional theology also maintained that there is an ‘innate’ or ‘implanted’ knowledge of God or gods. It will be argued that CSR and theology can be related, yet not in a straightforward manner. After sketching out in what sense CSR calls religion ‘natural’ and how it describes ‘supernatural agents’, this article explores some examples of the traditional theological doctrine of an ‘implanted’ knowledge of God. It shows that the reliability of such an ‘implanted’ knowledge of God was disputed among theologians and, even if it was affirmed, had an ambiguous position in theology. This also applies to CSR if it is to be related to the traditional theological doctrine. There are illuminating convergences between CSR and theology but also considerable divergences. Both, however, prove significant for theology.     

Differential effects of congenital left and right brain injury on intelligence

IQ performance was compared in 28 prepubertal children with unilateral left vs. right hemisphere preperinatal injury. Results indicated statistically superior FSIQ and VIQ in the left-lesioned group. Findings were interpreted as consistent with the hypothesis of a left-right maturational gradient, whereby early right hemisphere damage has a more severe effect on overall intellectual functioning than early left injury. Findings also lend support for a greater crowding effect, as seen in the sparing of verbal skills, after early left hemisphere injury.     

Adding sound to lipread lists: The effects on serial recall of adding an auditory pulse train and a pure tone to silently lipread lists

These investigations examined subjects’ serial recall of lipread digit lists accompanied by an auditory pulse train. The pulse train indicated the pitch of voiced speech (buzz-speech) of the seen speaker as she was speaking. As a purely auditory signal, it could not support item identification. Such buzz-speech recall was compared with silent lipread list recall and with the recall of buzz-speech lists to which a pure tone had been added (buzz-and-beep lists). No significant difference in overall accuracy of recall emerged for the three types of lipread list; however, there were significant differences in the shape of the serial recall function for the three list types. Recency characterized the silent and the buzz-speech lists, and these lists differed in their varying susceptibilities to a range of speechlike suffixes. By contrast, adding a pure tone to a buzz-speech list (buzz-and-beep) produced little recency and no further recall loss as a function of suffix type. We discuss these effects with reference to the contrast betweensensory-similarity and speechlikeness accounts of auditory recency and suffix effects. Sensory similarity accounts cannot capture the effects reported here, but processing in a speech mode (buzz-and-beep) need not always lead to recency effects like those resulting from clearly heard or lipread lists.
