Further evidence for phonological constraints on visual lexical access: TOWED primes FROG

If the phonological codes of visually presented words are assembled-rapidly and automatically for use in lexical access, then words that sound alike should induce similar activity within the internal lexicon.Towed is homophonous with TOAD, which is semantically related tofrog, andbeach is homophonous withbeech, which is semantically related totree. Stimuli such as these were used in a priming-of-namingtask, in which words homophonous with associates of the target words preceded the targets at an onset asynchrony of 100 msec. Relative to spelling controls (trod, bench), the low-frequencytowed and the high-frequencybeach speeded up the naming offrog andtree, respectively, to the same degree. This result was discussed in relation to the accumulating evidence for the primacy of phonological constraints in visual lexical access. nt]mis|This research was supported in part by National Institute of Child Health and Human Development Grants HD-08945 and HD-0 1994 to the first author and Haskins Laboratories, respectively.     

Hypothalamo-pituitary-adrenocortical axis function and hedonic behavior in adult male and female rats prenatally stressed by maternal food restriction

Neuroendocrine activation during stress is affected by many factors contributing to the variability of the stress response. The present study was aimed at evaluating long-term changes in hypothalamo-pituitary-adrenocortical (HPA) axis function and in hedonic behavior in adult offspring prenatally stressed by maternal food restriction, with attention on possible gender differences. Adult offspring were blood sampled via a tail artery cannula. Prenatally stressed females had significantly higher adrenal weights compared to males. Plasma ACTH levels, which rose in response to acute stress induced by handling, were significantly higher in females compared to those in males. A similar pattern was found in plasma corticosterone. The rise in ACTH levels was more pronounced in prenatally stressed rats though the rise in corticosterone failed to be modified. Corticotropin releasing hormone (CRH) and proopiomelanocortin mRNA levels in the hypothalamic paraventricular nucleus and anterior pituitary, respectively, were found to be unchanged. The present experiments failed to reveal a decrease in hedonic behavior in prenatally stressed rats. In contrast, in male offspring a tendency to a higher sucrose preference was observed. These data together with observed changes in hormone and CRH mRNA levels indicate that the gestational stress used did not result in a depression-like state in adult offspring.     

Psychosocial correlates of contraceptive practices during late adolescence

This article reviews the literature on psychosocial correlates of contraceptive practices among sexually active late adolescents (primarily college undergraduates). It seeks to help identify subgroups of adolescents who either do not use or misuse contraceptive means, putting them at risk for unwanted pregnancy, AIDS, and other sexually transmitted diseases. The intent is to promote further research on those variables with the most potential for predicting contraceptive behaviors, which will assist in the development and implementation of effective prevention and intervention programs.     

Rosa Luxemburg, “The Russian Revolution”

The essay concerns the highly controversial pamphlet of Rosa Luxemburg The Russian Revolution (1918/1922), in which Luxemburg criticizes Lenin’s post-revolutionary policies, in particular his dissolution of the Constituent Assembly, an elected body. The essay reviews the history of the text’s publication and the intense debate, which continues to this day, over whether or not Luxemburg changed her mind on its central critique. At stake in the argument is not only Luxemburg’s evaluation of Lenin’s actions but also the correct weighting to be given to the two components in the central Marxist–Leninist dialectic of revolution: spontaneity and consciousness. In elaborating this point the essay brings in examples from the writings of Lukács and Stalin, and also discusses the dialectic’s centrality in socialist realism.     

A longitudinal study of psychosocial distress in breast cancer: prevalence and risk factors

This longitudinal study was conducted among 102 women with non-metastasic breast cancer to identify the time evolution and prevalence of distress at specific times through diagnosis and treatment of disease: preliminary diagnosis, surgery, definitive diagnosis and chemotherapy. Additionally, the study aimed to examine the role of demographic, medical and psychosocial factors on distress. The results indicated that prevalence of distress was higher at initial diagnosis (25%) than the following time points (approximately 17%). The differences inter-individuals in the levels of distress were observed over the four assessments. No relation between distress and demographic and medical factors was found. However, psychosocial aspects were significant risk factors. Patterns of emotional suppression and specific coping responses like helplessness/hopelessness, anxious preoccupation, cognitive avoidance and fatalism were positively related to distress, whereas fighting spirit and perceived social support showed a protective role. Moreover, helplessness/hopelessness and anxious preoccupation jointly predicted 75% of cases and 98% non-cases of distress. Finally, a mediational model between emotional suppression and distress through helplessness/hopelessness was tested. Results support the necessity of routine distress screening all through the illness. Implications of data for psychosocial interventions with breast cancer patients are highlighted.     

Socio-demographic determinants of infant neurodevelopment at 18 months of age: Mother-Child Cohort (Rhea Study) in Crete, Greece

Studies on determinants affecting child development are still limited in Greece. The aim of the present study was to describe the socio-demographic characteristics associated with neurodevelopment in infants aged 18 months in the Mother-Child Cohort (Rhea Study) in Crete, Greece. A total of 599 (72.9%) mothers agreed to participate in the neurodevelopment protocol and 612 infants (586 singletons and 26 twins) were assessed by means of the Bayley Scales of Infant and Toddler Development (3rd edition). The present analysis includes 605 infants. Multivariable linear regression models were implemented to examine the associations between the Bayley-III standardised scores and different parental and infant characteristics, also adjusting for quality of assessment. Girls were found to have better neurodevelopmental outcomes in cognitive, receptive and expressive communication, fine motor and social-emotional development. Maternal higher education was positively associated to almost all aspects of infant neurodevelopment assessed. Increasing number of older siblings was negatively associated with cognitive development, communication skills and gross motor development. Our results, also, suggest a positive effect of maternal employment on infants' receptive and expressive communication, and gross motor scores. The results of the present study suggest that in the population on Crete social and environmental factors contributed more to infants' neurodevelopment at 18 months than biological factors.     

Sexual behavior in Spanish adolescents of divorced parents

Marital breakup has been associated with numerous behavioral problems in children, such as sexual risk behaviors. This research is the first to examine sexual behaviors of Spanish adolescents related to whether their parents were married or divorced. Participants were 342 boys and girls aged between 14 and 18 years. The sample provided confidential information about their sexual behavior and birth control methods. Significant differences were only found in percentages of adolescents who had engaged in mutual masturbation, intercourse, or oral sex, and who had practiced these sexual relations in the last six months, in both cases, they were higher when the parents had broken their marital relationship. Regarding adolescents of divorced parents, engaging in intercourse is more likely in older teenagers who live with a stepparent. Moreover, older adolescents who were younger when parents divorced and who live in a reconstituted family, have more sexual partners. These and other findings are discussed.     

Sociodemographic, clinical and outcome differences among anxiety disorders

The aims of this paper are to analyze differences in sociodemographic and clinical characteristics among the various anxiety disorders treated in a Psychology Clinic, and the results of treatment in each anxiety disorder. Data from 282 patients of University Psychology Clinic at the Complutense University of Madrid, who had at least one diagnosis of anxiety according to DMS-IV-TR criteria, were analyzed. The most frequent anxiety disorders were nonspecific anxiety disorder (19.1%) and social phobia (18.8%). Significant differences were observed according to sex (in all disorders, the percentage of women was significantly higher than that of men, except for obsessive-compulsive disorder). Unspecific anxiety disorder required a smaller number of assessment and treatment sessions, whereas obsessive-compulsive disorder required a greater number of sessions. There were no significant differences between the percentage of patients who completed treatment and dropout rates in specific phobia, general anxiety disorder and obsessive-compulsive disorder. Differences between epidemiological and clinical data are discussed.     

Are lies more wrong than errors? Accuracy judgments of inaccurate statements

People are often mistaken when estimating and predicting quantities, and sometimes they report values that they know are false: they lie. There exists, however, little research devoted to how such deviations are being perceived. In four vignette studies, participants were asked to rate the accuracy of inaccurate statements about quantities (prices, numbers and amounts). The results indicate that overstatements are generally judged to be more inaccurate than understatements of the same magnitude; self-favorable (optimistic) statements are considered more inaccurate than unfavorable (pessimistic) statements, and false reports (lies) are perceived to be more inaccurate than equally mistaken estimates. Lies about the future did not differ from lies about the past, but own lies were perceived as larger than the same lies attributed to another person. It is suggested that estimates are judged according to how close they come to the true values (close estimates are more correct than estimates that are less close), whereas lies are judged as deviant from truth, with less importance attached to the magnitude of the deviation.     

No postnatal maternal effect on male aggressiveness in wild-derived strains of house mice

Male aggressiveness is a complex behavior influenced by a number of genetic and non-genetic factors. Traditionally, the contribution of each of these factors has been established from experiments using artificially selected strains for high/low aggressive phenotypes. However, little is known about the factors underlying aggressive behavior in natural populations. In this study, we assess the influence of genetic background vs. postnatal maternal environment using a set of cross-fostering experiments between two wild-derived inbred strains, displaying high (STRA, derived from Mus musculus domesticus) and low (BUSNA, derived from Mus musculus musculus) levels of aggressiveness. The role of maternal environment was tested in males with the same genetic background (i.e. strain origin) reared under three different conditions: unfostered (weaned by mother), infostered (weaned by an unfamiliar dam from the same strain), and cross-fostered (weaned by a dam from a different strain). All males were tested against non-aggressive opponents from the A/J inbred strain. Resource-holding potential was assessed through body weight gains and territory ownership. The STRA males were shown to be aggressive in both neutral cage and resident-intruder tests. On the contrary, the BUSNA males were less aggressive in all tests. We did not find a significant effect of postnatal maternal environment; however, we detected significant maternal effect on body weight with differences between the strains, fostering type and interactions between these factors. We conclude that the aggressiveness preserved in the two strains has significant genetic component whose genetic basis can be dissected by quantitative trait loci analysis.
