Epigenetic inheritance and the intergenerational transfer of experience

Currently, behavioral development is thought to result from the interplay among genetic inheritance, congenital characteristics, cultural contexts, and parental practices as they directly impact the individual. Evolutionary ecology points to another contributor, epigenetic inheritance, the transmission to offspring of parental phenotypic responses to environmental challenges-even when the young do not experience the challenges themselves. Genetic inheritance is not altered, gene expression is. Organismic pathways for such transmission exist. Maternal stress during the latter half of a daughter's gestation may affect not only the daughter's but also grand-offspring's physical growth. The author argues that temperamental variation may be influenced in the same way. Implications for theory and research design are presented along with testable predictions.     

Impact of substance abuse and child maltreatment training on service utilization in a rural setting

Substance abuse and child maltreatment have been recognized as co-morbid problems encountered in families presenting in the child protective services (CPS) system. Nonetheless, utilization rates of substance abuse treatment services have generally lagged well behind what the research would suggest are prevalence rates for substance abuse disorders in this population, suggesting problems in recognition and referral practices among CPS workers. In response to this, 25 training programs were funded by the National Center on Child Abuse and Neglect. This study reports data from one program. Trainees indicated a high level of satisfaction and demonstrated significant knowledge gains. More importantly, utilization of substance abuse services increased significantly across time in a multi-county region receiving training relative to a comparison region receiving none. The gain was limited, suggesting that while increased knowledge may translate into increased service utilization, additional barriers to accessing needed services must also be addressed.     

The World Health Organization WHOQOL-100: tests of the universality of Quality of Life in 15 different cultural groups worldwide.

The World Health Organization Quality of Life assessment (WHOQOL-100) was developed simultaneously across 15 international field centers and includes 24 facets relating to quality of life, which are grouped into 4 larger domains: physical, psychological, social relationships, and environment. It also includes 1 facet examining overall quality of life and general health perceptions. This article examines the extent to which the WHOQOL-100 assesses quality of life perceptions in different cultures and whether it is structurally comparable in these cultures. Regression analysis showed all 4 domains to be important in assessing quality of life in each of the 15 centers. Structural equation modeling suggested further support for the proposal that there are universal facets and domains that are cross-culturally important in determining quality of life and suggested that the ordering of facets within domains is comparable across cultures.     

Genetic Testing Considerations in Breast Cancer Patients

Genetic testing is now feasible for a growing number of cancers. Although the implications for unaffected relatives have been widely described, the impact of the tests on affected individuals are often not recognized. We present and discuss four cases that highlight some of the issues—for example, feelings of guilt and anxiety, intrafamilial conflict, and support needs—that may arise in testing affected individuals. We offer some suggestions to aid in the approach to such testing.     

Overconfidence in estimation: Testing the anchoring-and-adjustment hypothesis

People are frequently overconfident in the accuracy of their estimates of uncertain quantities. The present study requested 50%- or 90%-confidence ranges. Overconfidence is shown when less than the target percentage of ranges include the true value. Tversky and Kahneman (1974) proposed that people use an anchoring-and-adjustment heuristic: They begin with a starting value, one supplied to them or generated by them, and insufficiently adjust their estimates around this anchor. The present data support the proposed anchoring process. If subjects receive another person's point estimates, their own implicit point estimates are correlated with these values. However, anchoring- and-adjustment processes do not invariably produce overconfidence. Subjects who receive anchors are no more overconfident than are those who do not receive anchors. If subjects are required to produce a point estimate first, overconfidence decreases; processes involved in explicitly displaying the point estimate are implicated. Overconfidence may occur because people do not realistically assess their estimation ability.     

Derivation and application of a unit scoring system for the strong vocational interest blank for women

Scoring keys, based upon unit weights, were made up for fourteen occupations of theStrong Vocational Interest Blank for Women. The study here presented of scores obtained in using these keys, in comparison with scores obtained from Dr. Strong's keys, indicates, for 551 women at the University of Rochester, that the new, unit-weighted keys are valid for all practical purposes and make possible a great saving in scoring time.     

The Peabody Individual Achievement Test

The relationship of the Peabody Individual Achievement Test (PIAT) to the California Achievement Tests (CAT) and to the Wechsler Intelligence measures was assessed on adolescent psychiatric inpatients. Correlations among all three tests were high, but differentially so with advancing levels of the CAT. Further, age and grade estimates derived from the PIA T more closely approximated the youngster's actual age and grade placement than did those derived from the CAT.     

Influences of Gender as a Basic-Level Category in Person Perception on the Gender Belief System

The use of gender as an organizing category in social perception and its influence on the gender belief systemwere investigated. A modified version of the Role Construct Repertory Test and selected self-report questionnaires were completed by 190 college students (165 women and 25 men). All the participants used gender to organize their person schemas, and using gender in this way related positively to gender stereotyping. Both sexist gender attitudes and use of gender as an organizing category predicted gender stereotyping. Components of the gender belief system were only correlated if they were conceptually similar. The findings are congruent with gender transcendent and multifactorial gender identity theories.     

Alexander Bain's Mind and Body (1872): An underappreciated contribution to early neuropsychology

Alexander Bain (1818–1903) is well known for his two influential textbooks, The senses and the intellect (1855) and The emotions and the will (1859). In comparison, Bain's Mind and body: The theories of their relation (1872) has been of limited interest to historians, and it is here where he presents one of the first neural network models. This paper addresses the historical foundations of Bain's neural network model and explores some of his primary influences. Additionally, this study addresses some of the reasons Bain's Mind and Body did not receive the historical notice his earlier works garnered.
