A ray of light about frozen embryos.

The Tennessee Supreme Court's decision in Davis v. Davis, a case that raises the question of how to allocate frozen embryos in the event of divorce, addresses many of the legal issues posed by in vitro fertilization. The decision considers the interests of the progenitors as well as of the children who may result. For example, the court held that gamete providers' discretion regarding the disposition of embryos can be limited only when their decisions would harm the children who might be born. The court also made clear that efforts to seek genetic parenthood are protected only when accompanied by a desire to raise the resulting children, a conclusion that also affects other reproductive technologies. In addition to elaborating an analytic framework, the court set guidelines for resolving disputes when the couples had made no prior agreements, including holding that while the embryos are ex-utero the desire to avoid genetic parenthood almost always trumps the wish to become a parent. The well-reasoned analysis in Davis v. Davis should help shape legal and ethical discussion regarding the use of in vitro fertilization for many years to come.     

Contributions of a supportive work environment to parents' well-being and orientation to work

Examined the joint and unique contributions of informal social support in the workplace and formal, family-responsive benefits and policies provided by employers to the job-related attitudes and personal well-being of employed parents with a young child. Eighty married men, 169 married women, and 72 single women with a preschool child completed a survey concerning social support from co-workers and supervisor, utilization of family-responsive benefits and policies, readiness to leave the employer for additional benefits, job satisfaction, organizational commitment, role strain, and health symptoms. Among the findings: (a) Fathers and mothers expressed equal levels of job satisfaction and organizational commitment, but mothers reported more role strain and health symptoms; (b) nearly 48% of married women's organizational commitment was accounted for by measures of support in the workplace; (c) informal social support at work was significantly more important to men's well-being than that of women; and (d) formal, family-responsive policies appeared more consequential for the prediction of women's role strain, perhaps because of women's greater responsibility for adjusting work life to meet the demands of family roles.     

Are words represented by nodes?

Semantic priming in a lexical decision task was investigated with concurrent pretarget and posttarget primes. The posttarget prime also served as a pattern mask of the lexical decision target. Forward priming is defined as the presence of a semantically related pretarget prime and an unrelated posttarget prime. Backward priming is defined as the presence of a semantically related posttarget prime and an unrelated pretarget prime. Forward and backward priming were compared both when the nonword foils were "legal" and when they were "illegal" with respect to English orthography. Predictions were derived for two general approaches to word recognition: spreading-activation and expectancy-set theories. Both approaches assume that word representations occupy distinct, nonoverlapping locations in memory. Backward-prime facilitation was equivalent to forward-prime facilitation when nonword foils were illegal; however, backward-prime facilitation was not significant when nonword foils were legal. These results challenge both approaches. The proposed solution uses semantic-space (distributed) representations that are functionally unitized by a resonant matching (verification) process.     

Generativity and Erikson's “belief in the species”

Generativity is the concern for guiding and promoting the next generation through such creative behavior as parenting, teaching, mentoring, leading, and generating products and outcomes that benefit others. Erikson (1963) has argued that in order to be generative in adulthood, people must have a fundamental “belief in the species” or a faith that human progress is possible and worth working toward. The present study focuses on hope and trust concerning the self and others (Erikson's “belief in the species”). In addition, however, the study examines the relation between generativity and personality traits, in this case, dominance, leadership, self-absorption, and nurturance. A sample of 70 adults was administered (1) a series of self-report questionnaires converging on Erikson's idea of belief in the species, (2) a self-report scale assessing generativity, (3) measures of personality traits, and (4) two open-ended measures of generativity requiring subjects to describe life commitments and creative endeavors. The results provide modest support for Erikson's claim of a link between belief in the species and generativity, with significant positive correlations obtained (1) between self-report generativity and two measures of belief in species and (2) between generativity assessed through life commitments and one measure of belief in the species. In addition, the personality trait of nurturance was positively related to all three generativity measures. Problems and issues in the assessment of generativity are discussed.     

Age differences in the acculturation process

Age differences were assessed in a conceptual model that seeks to explain how acculturation affects psychological well-being among Mexican Americans. The data were from a national probability sample of 859 persons of Mexican decent. It was hypothesized that low acculturation creates financial stress. Moreover, low acculturation and financial stress were in turn predicted to erode feelings of personal control and self-esteem. Finally, diminished feelings of control and low self-esteem were hypothesized to exert a negative impact on psychological well-being. When data from respondents of all ages was assessed, empirical support was found for all of the hypotheses except the linkage between acculturation and financial stress. However, few age differences emerged in the model. The authors conclude that older Mexican Americans may not be more vulnerable to the stressors associated with acculturation.     

Memories of a bicycle tour

One person's memories of a 47-day bicycle tour of Scandinavia were tested 3–4 months later. The tests assessed frequency, spatial, and temporal knowledge of events. Results indicated that frequency judgements were based on some combination of counts of discrete event memories and a general impression of the tour. Episodic memories showed clear variation as a function of where events had occurred, and judged and actual locations of episodes were strongly related. In fact, knowledge of the week in which something had happened appeared to hinge on where in a sequence of locations it was thought to have taken place. The apparent dependence of temporal judgements on spatial information is consistent with other findings in the literature indicating that temporal memories about past events are derived from a variety of other associated information, much of which is temporally referenced.     

Acquired affective-evaluative value: conservative but not unchangeable

In a previous study on Evaluative Conditioning it was found that unlike signal-learning, evaluative learning is resistant to extinction. In the present experiment we tried to replicate and corroborate this finding. In addition, we investigated the effectiveness of a counterconditioning procedure to alter acquired evaluative value. On a within-subject base (n = 30), it was found that the mere contingent presentation of neutral with (dis)liked pictures of human faces was sufficient to change the affective-evaluative tone of the originally neutral stimuli in (negative) positive direction. Next, we replicated the finding that an extinction procedure does not have any influence on the acquired evaluative value of the originally neutral stimuli, and this even in subjects fully aware of the extinction presentations. We demonstrated the effectiveness of a counterconditioning procedure to alter acquired evaluative value, and in addition, found some evidence that awareness of the counterconditioning manipulations is not a prerequisite for its effectiveness. The theoretical consequences of these findings are phrased in terms of a fundamental distinction between signal-learning and evaluative learning, and some important implications for the behavioral treatment of affective-emotional disorders are suggested.     

The relations between sex-typed play and preschoolers' social behavior

For decades toy choice has been a very popular measure of children's sex-role adoption. In the present study, the relations between choice of masculine, neutral, or feminine toys and other social behaviors (sex typed and non-sex typed) were examined. The social behaviors (socializing, requesting assistance, prosocial behaviors, aggressive/defensive behaviors) and toy choices of 33 preschool children were observed in their classrooms. Only two behaviors were found to be sex typed (socializing with peers and spontaneous prosocial behavior), and both of these behaviors were related to toy choice. Toy choice was also related to helping. Among boys, masculine toy choice was associated with requesting assistance from teachers. When toy choice was classified as masculine, androgynous, and feminine, only sociability toward peers was related to toy choice. The results are discussed in terms of their implications for the continued use of toy choice as a measure of sex-role adoption.The authors wish to express their gratitude to Rene Dodez for her assistance in data analysis and to the children and teachers at the Child Study Laboratory. We also appreciate the contributions of Drs. Laurie Chassin, Jerry Harris, Susan Somerville, Sharlene Wolchik, and Antonette Zeiss. This research was completed by the first author in partial fulfillment of the masters of arts degree at Arizona State University.
