Observer Influences on Fathers and Mothers: An Experimental Manipulation of the Structure and Function of Parent – Infant Conversation

From studies over the past 20 years four contrasting hypotheses can be made about the nature of parent–infant communication: (1) mothers and fathers display similar skills to their infants and do not exert a differential influence on their development; (2) fathers are less sympathetic to their infants' level of development and therefore inadvertently stretch the child's development more than mothers; (3) both parents differentially socialize their sons' and daughters' early communicative skills; (4) any apparent differences between parents reflect their expectations about being observed. To examine these hypotheses together, this experiment records the communication of 10 mother–infant and 10 father–infant dyads in two conditions: when an observer was present or absent. The analysis revealed two patterns. Firstly, in keeping with most research on parent–child communication, mothers and fathers both simplified their speech to their infants in similar ways. Secondly, both the structure and function of parental communication showed differences between the two conditions and many of these differences were moderated by interactions between condition and sex of parent or child. The data thus provide more support for the first and fourth hypotheses cited above. It is suggested that analyses of parent–infant interaction should move away from simple assumptions about parental ‘influences’ upon children's development to consider the subtleties of different parental styles in different settings.     

Empathy as a cognitive inhibitor of interpersonal aggression

The studies presented in this paper examined empathy, especially perspective taking, as a potential inhibitor of interpersonal aggression. The theoretical rationale for these investigations derived from Zillmann's [(1988): Aggressive Behavior 14: 51–64] cognitive excitation model. Study 1 revealed that dispositional empathy correlates negatively with self-reported aggression and with conflict responses that reflect little concern for the needs of the other party. Empathy also was positively related to constructive responses to interpersonal conflict (i. e., those that do involve concern for the needs of the other party). In Study 2, perspective taking was manipulated with instructions to subjects prior to participation in a reaction-time task designed to measure aggression. When threat was relatively low, subjects who were instructed to take the perspective of the target responded less aggressively than did those who had been instructed to focus on the task. Study 3 examined the effect of dispositional perspective taking on verbal aggression. Threat was manipulated in terms of the combination of provocation and gender of the interactants. As predicted, perspective taking related to aggression inhibition under conditions of moderate threat–for males under low provocation and females under high provocation. These effects were predicted and explained in the context of the cognitive-excitation model. © 1994 Wiley-Liss, Inc.     

Parental influence on children's self-estimated agressiveness

Parental influence on children's self-estimated aggressivences was measured with inventories. One hundred seventy-four adolescents (85 girls and 89 boys; mean age 13.6 years, SD 0.7) from a suburban school, known as prone to problems of aggression, served as subjects. The dependent variable aggresive personality was measured with the Buss-Durkee Hostility Inventory [J consult Psychol 21:343, 1974]. Parental influence was measured with scales specifically developed for the present research. the subjects estimated: 1) their emotional relation to each parent; and 2) their perception of how their parents a and b) behave when angry c) at home and d) with their peers. The results revealed clearly gender-specific efects: mothers and fathers affected sons and daughters differently. According to LISREL analyse, mother had a clearly stronger impact on sons, while fathers had a slightly stronger effect on daughters. In the case of fathers, hiting and alcohol abuse were, in addition to a negative emotional relationship, strong predictors of daughter's aggresivencess. However, aggressive fathers tended in general to get a counterreaction with their sons, leading to low aggressiveness with the same type of behavior in their case. Typical maternal predictors of children's aggressivencess were shouting and a negative emotional relationship. In the case of daughters, the former was a more important predictor than the latter, but in the case of sons, it was the other way around. Modeling effects were revealed: subjects imitated their parents' styles of behavior in anger, however, with different patterns at home and with peers. The results may be interpreted as support for both the cognitive learning and the frustration-aggression hypotheses as sources for aggressive behavior. © 1992 Wiley-Liss, Inc.     

Sex and post-menopause hormone therapy effects on hippocampal volume and verbal memory

Many studies suggest sex differences in memory and hippocampal size, and that hormone therapy (HT) may positively affect these measures in women; however, the parameters of HT use that most likely confer benefits are debated. We evaluated the impact of sex and postmenopausal HT use on verbal learning and memory and hippocampal size in 94 cognitively intact women and 49 men. Using analysis of covariance that controlled for age and education, women had better total word learning and delayed verbal memory performance than men. HT analyses showed that non-HT users performed similarly to men, while HT users performed better than men in Delayed Memory regardless of whether use was current or in the past. Women had larger hippocampal volumes than men regardless of whether they were HT users. Using univariate linear models, we assessed group differences in the predictive value of hippocampal volumes for verbal learning and memory. Hippocampal size significantly predicted memory performance for men and non-HT users, but not for HT users. This lack of relationship between hippocampal size and verbal learning and memory performance in HT users suggests HT use may impact memory through extra-hippocampal neural systems.     

Preferences for ‘Gender‐typed’ Toys in Boys and Girls Aged 9 to 32 Months

Many studies have found that a majority of boys and girls prefer to play with toys that are typed to their own gender but there is still uncertainty about the age at which such sex differences first appear, and under what conditions. Applying a standardized research protocol and using a selection of gender‐typed toys, we observed the toy preferences of boys and girls engaged in independent play in UK nurseries, without the presence of a parent. The 101 boys and girls fell into three age groups: 9 to 17 months, when infants can first demonstrate toy preferences in independent play (N = 40); 18 to 23 months, when critical advances in gender knowledge occur (N = 29); and 24 to 32 months, when knowledge becomes further established (N = 32). Stereotypical toy preferences were found for boys and girls in each of the age groups, demonstrating that sex differences in toy preference appear early in development. Both boys and girls showed a trend for an increasing preference with age for toys stereotyped for boys. Theoretical implications of the findings are discussed with regard to biological predispositions, cognitive development and environmental influences on toy preference.

An evaluation of sex and cultural differences in arithmetic retrieval-induced forgetting

Retrieval practice of arithmetic facts (e.g. 2?×?3) can interfere with retrieval of other, closely related arithmetic facts (e.g. 2?+?3), increasing response time (RT) and errors for these problems. Here we examined potential sex and culture-related differences in arithmetic retrieval-induced forgetting (RIF). This was motivated by re-analyses of several published arithmetic RIF data sets that appeared to show that the effect occurred for women but not men. Experiment 1 (n?=?72) tested for possible sex differences in a diverse but predominantly Canadian university sample. Experiment 2 (n?=?48) examined potential sex differences in native Chinese participants, which previous research indicated may not be susceptible to the RIF effect for a particular subset of small addition problems (sum?≤?10). In Experiment 1, we found no evidence that the addition RIF effect differed between male and female adults. In Experiment 2, the Chinese adults showed RIF for tie problems (e.g. 2?+?2, 3?+?3, etc.) regardless of sex, but neither sex presented RIF for small non-tie addition problems. The results indicated that the RIF effect is not gender specific, and there might not be strong memory retrieval competition between addition and multiplication facts for non-tie problems in Chinese adults.     

Évolutions législatives et enjeux éthiques liés à la prise en charge des enfants ayant un trouble de la différenciation sexuelle (DSD)

The ethical dilemma concerning the care of children with a disorder of sex development opposes patients who have benefited from undeniable medical and surgical advances over the past 30 years and patients who have suffered from initial carek, experienced as “torture” or “genital mutilation”. The latter, grouped into advocacy organization (including the International Intersex Organization), recommend that genital operation of children must be avoided until they can give their prior consent, in the name of the fundamental right to self-determination and physical integrity. This “free choice” left to the child would not take into account the opinion of the parents or that of the medical team, nor any psychological, social and societal consequences, nor the risks of late surgery. Recent legislative developments are exposed. The interest of legislating on these delicate situations affecting the most intimate is questioned, especially as they are of great complexity because of the heterogeneity of genetic causes and family situations. Medico-surgical Societies, in connection with patient associations denounce this media hold by “Intersex” activists, who are not representative of the patients having been managed more recently. They advocate to continue to understand these situations on a case-by-case basis, leaving the choice to the parents to allow the child to grow up in a gendered body.     

Mother's prenatal and postpartum depression symptoms and infant's sleep problems at 6 months

Mother's prenatal and postpartum depression have been associated with infant's sleep problems. This study aimed to analyze (a) the effects of mother's prenatal and postpartum depression symptoms, including the effects of prenatal and postpartum anxiety and depression scores of the Edinburgh Postnatal Depression Scale (EPDS), on infant's sleep problems at 6 months, and (b) the interaction effect between mother's prenatal and postpartum depression symptoms and infant's sex on infant's sleep problems at 6 months. The sample was comprised of 164 mother–infant dyads whose mothers completed measures of depression at the third trimester of pregnancy, 2 weeks, 3 and 6 months postpartum and a measure of infant's sleep problems at 6 months (CSHQ-I). Mother's prenatal depression symptoms, specifically depression scores of the EPDS, predicted more infant's sleep anxiety and daytime sleepiness, while mother's depression symptoms at 2 weeks postpartum, specifically anxiety scores of the EPDS, predicted more bedtime resistance and CSHQ-I total scores at 6 months. Boys of mothers with more prenatal depression symptoms presented more sleep anxiety at 6 months. Both mother's prenatal and early postpartum depression symptoms have a negative effect on the emergence of infant's sleep problems. Additionally, boys seem more vulnerable to mother's prenatal depression symptoms.     

Integrating Sex Therapy Interventions with Couple Therapy

This conceptual/clinical paper presents a couple, integrative, psychobiosocial model of assessment, treatment, and relapse prevention for common sexual dysfunctions. The goal is to encourage couple therapists to integrate sexual permission-giving, scientifically and clinically relevant sexual information and guidelines, and specific sexual suggestions/interventions into their couple work. The artificial barriers between couple and sex therapy is to the detriment of couples who need to address intimacy and sexuality problems.     

Personality types and risky health behaviors in Norwegian students

Typological research has received increasing interest in recent years, but is still regarded as substandard by personality psychologists. The current investigation shows how a typological approach can enhance our understanding of the influence of personality on risky health behaviors. We focused on Torgersen's eight personality types that represent unique configurations of high and low Extraversion, Neuroticism, and Constraint (Vollrath & Torgersen, 2000). Participants were 606 Norwegian university students. Measures assessed personality factors, smoking, abuse of drugs and alcohol, drunk driving, and risky sexual behaviors. Results replicated earlier research showing that types combining either high Extraversion and low Constraint (Hedonists, Impulsives) or high Neuroticism and low Constraint (Insecures) engage in more risky health behaviors. The discussion focuses on demonstrating that the study of types is a valuable supplement to the dimensional tradition in personality psychology.
