An Oral History of the National Society of Genetic Counselors

Master's level genetic counselors formed a professional society in 1979, 8 years after the first master's degree training program graduation. This paper presents an oral history of the early years of the National Society of Genetic Counselors (NSGC), reviews the symbiotic development and definition of a profession and a professional society, and discusses events and achievements attributed to the NSGC since its incorporation. This retrospective historical account is based on personal and collective oral history, NSGC archival material and other sources.     

Developmental changes in death anxiety in childhood

A sample of 49 children divided into three age groups (3–4 years, 7–8 years, and 10–11 years) responded to a pictorial derivation of Spielberger's State Anxiety Inventory for Children (STAIC). Three pictures were used as stimuli, in addition to words, for the measure of death anxiety. The intensity measure was the response to six Hebrew mood adjectives as the child chose one of seven schematic face drawings ranging from positive to negative expressions. Reliabilities were comporable to the longer versions of the Hebrew STAIC with older children. Findings indicated significant differences in anxiety scores between the age groups, with older subjects showing higher levels of anxiety. The advantage of a single measure of death anxiety appropriate for a wide age range is discussed, as well as the implication for a developmental pattern of death anxiety.     

Racial differences in intelligence: The importance of the executive system

The race-IQ controversy arose at a time when psychometric views of intelligence dominated. Little attention was paid to more process-oriented models in spite of the fact they provide alternative perspectives on the causes of individual differences in problem-solving. We hypothesized that much of the IQ spread commonly observed between black and white children can be attributed to differences in components of their executive systems, including the knowledge base, control processes, and metacognitive states. To test this possibility, black and white children who differed significantly on fluid and crystallized intelligence were tested on multiple tasks reflecting components of the executive systems as well as on perceptual efficiency tasks. Striking group differences were observed in metamemory, stragegy use, and general knowledge, but few reliable differences were found in perceptual efficiency. Regression analyses showed that different factors predicted fluid and crystallized intelligence, with metamemory predicting the latter but not the former. An implication of these findings has potential educational significance: training directed at executive skills, introduce at an early age, might elevate learning and problem-solving skills in black children, thereby reducing racial differences in crystallized intelligence.     

Snake aggregation pheromones: source and chemosensory mediation in western ribbon snakes (Thamnophis proximus)

Aggregation with conspecifics is a robust phenomenon among snakes that is mediated by chemical cues, although the source of such cues is unknown. Adult western ribbon snakes (Thamnophis proximus) discriminated between skin lipid extracts from conspecifics and those from a sympatric heterospecific snake, the corn snake (Elaphe guttata). Additionally, ribbon snakes were attracted to conspecific skin lipid-marked shelters when paired with control-marked shelters, but no preference was exhibited when shelters marked with E. guttata skin lipids were paired with control-marked shelters. Furthermore, prevention of chemical access to the vomeronasal organs of T. proximus eliminated the ability to respond to conspecific skin lipids. These results indicate that epidermal lipids are the source of chemical cues mediating attraction to shelters marked by conspecifics and that such signals are detected by the vomeronasal system.     

Testing Theoretical Explanations of Intention to Seek Care for a Breast Cancer Symptom1

The purpose of this research was to test theoretical explanations of intention to seek care promptly for a breast cancer symptom. Psychosocial variables (affect, expectations, values, and norms), habit, and facilitating conditions (e.g., insurance) regarding care seeking were proposed to influence intention to seek care promptly. Whether psychosocial variables and habit influenced intention directly or in interaction with facilitating conditions remained unclear. Other variables (i.e., clinical and demographic) were proposed to influence intention by mediation through the theoretical variables. Community-dwelling women without history of breast cancer (N= 99) responded to a questionnaire to assess study variables. In a hierarchical set regression, intention was first regressed on psychosocial variables, habit, and full insurance coverage for care, then on terms representing interactions of insurance coverage with psychosocial variables and habit, and lastly on clinical and demographic variables. Findings revealed that (a) anxiety (measure of affect), utility, (the product of expectations and values), and habit were related to intention, (b) having full insurance coverage did not moderate these relationships, and (c) after controlling for theoretical variables, family history of breast cancer was related inversely to intention. Implications for theory, research, and practice are delineated.     

Left-handedness: a marker for decreased survival fitness

Life span studies have shown that the population percentage of left-handers diminishes steadily, so that they are drastically underrepresented in the oldest age groups. Data are reviewed that indicate that this population trend is due to the reduced longevity of left-handers. Some of the elevated risk for sinistrals is apparently due to environmental factors that elevate their accident susceptibility. Further evidence suggests that left-handedness may be a marker for birth stress related neuropathy, developmental delays and irregularities, and deficiencies in the immune system due to the intrauterine hormonal environment. Some statistical and physiological factors that may cause left-handedness to be selectively associated with earlier mortality are also presented.     

Laboratory observations of trailing behavior in garter snakes.

Using a Y-maze apparatus, nine garter snakes were trained to follow an earthworm-extract trail. Correct trailing improved significantly as training progressed. All snakes were able to attain a trailing criterion of 8 out of 10 correct trials by the termination of training. For each trial, the number of tongue flicks each snake made was recorded and tongue flick rate calculated. Tongue flick rate was found to be highly characteristic and constant for individual subjects. In addition, running speed and tongue flick rate were found to be significantly correlated.     

Sexual assault history and use of health and mental health services

A history of sexual assault may be associated with increased current use of mental health and medical services because of the psychologically and physically disruptive consequences of assault. To test this hypothesis, we estimated rates of mental health and medical services use among 2560 randomly selected community residents, 343 of whom had been sexually assaulted. Sexual assault was associated with seeking both forms of care. Controls for demographic variables, psychiatric diagnosis, health status, and insurance suggested that assault increases use indirectly, through poor mental and physical health. Uninsured, assaulted respondents were especially likely to consult medical providers. Respondents assaulted during childhood were particularly likely to seek mental health care. Assault was more common among mental health service users than nonusers, and among women using medical services compared to female nonpatients. The high prevalence of assault among service users underscores the need for providers to recognize and treat sexual assault-related problems.
