Testing message diffusion in harmonic logistic curves

The growth of a population of knowers of a message was studied to test a human interactance hypothesis. The conditions investigated involvedpeople interacting in time, with the population pairing off randomly (i.e., determined by many, small, different influences) and transferring an attribute (i.e., an all-or-none act) at either a steady rate or a waning rate, subsequent to the originating stimulus. The mathematical expressions for these pre-conditions were the differential equations for the linear logistic for steady acting and the harmonic logistic for waning acting. Variant forms of these curves were developed. Two exploratory experiments, or pretests, comprised launching a coffee slogan in a town and imitating a badge wearer in a boys' camp. Since the activity rate waned harmonically in both cases, the harmonic logistic fit best in both the town and the camp as expected by the hypothesis.A paper read before Section K sponsored by the Committee on Social Physics of the AAAS Conference in Boston, December 30, 1953.

Influence of maternal gender-role beliefs and role satisfaction on daughters' vocational interests

We examined whether maternal gender-role ideologies and role satisfaction influence daughters' vocational interests. 152 female undergraduate students (Mage = 18.7 years), from predominantly white, middle- to upper-class homes, as well as their mothers and fathers, participated voluntarily. Students identified their career choices, completed a gender-role ideology scale and an identification with parents questionnaire, and reported their perceptions of their mothers' and fathers' gender-role ideologies and role satisfaction. Each parent completed a gender-role ideology scale and a role satisfaction questionnaire. Path analyses support a model in which actual and perceived maternal attitudes (n= 135) influence the gender-role ideologies of daughters, which in turn influence the gender stereotyped nature of daughters' career choices (Q= .90; W= 14.00, p> .05); furthermore daughters' maternal identification moderated the relationship between perceived maternal gender-role ideology and own gender-role ideology. A similar model substituting fathers' attitudes (n= 128) did not fit the data. The results indicate how maternal attitudes influence daughters' career choice, and support the role of family socialization on children's career aspirations.     

Lead and hyperactivity: Lead levels among hyperactive children

Previous work has demonstrated an association between hyperactivity and increased body lead burdens in school-age children. In the present study it is shown that within a group of hyperactive children those for whom an organic etiology is present have lead burdens lower than in those for whom no apparent cause could be found. These data lead us to reject the notion that hyperactivity per se is responsible for the acquisition of elevated lead levels, and further strengthen the suspicion that for some children lower lead level absorption may be implicated in the development of the hyperkinetic disorder.This work was supported in part by the Office of Child Development, Grant #OCD-CB482.

Lip reading in infants: Attention to speech presented in- and out-of-synchrony

Twelve 10- to 16-week-old infants were presented with nursery rhymes spoken with speech sounds and lip movements in-synchrony and out-of-synchrony by 400 msec. Two observers measured the amount of time the infants did not attend to the two types of stimuli. The results showed that the infants attended significantly less to the out-of-synchrony presentation than to the in-synchrony presentation. This finding was interpreted as an indication that young infants are aware of the congruence between lip movements and speech sounds.     

The role of the school psychologist: Teachers'' preferences as a function of personal and professional characteristics

Teachers were surveyed concerning the importance of 12 potential roles for school psychologists (e.g., counseling, case or program consultation, community liaison, psychodiagnostics). Results showed that direct and remedial services which did not require the school psychologist to intrude on the teacher's prerogatives were in general considered to be most important. However, teachers who reported using “open education” methods were significantly more likely to value more indirect, preventive, and collaborative school psychology services than their colleagues. Grade level taught, gender, experience, and teaching specialty had virtually no effect on respondents' ratings of the school psychologist roles.     

The 1979 division 27 award for distinguished contributions to community psychology and community mental health: Emory L. Cowen

Summary The metaphor of the paper's title offers a framework for a brief summary. Effective wooing of primary prevention requires that we take seriously, and adhere to, its clear, sensible defining guidelines; systematize, and further develop, its generative base; use that base to guide the formulation of new primary prevention programs; further develop frameworks to promote informed choices of programs derecions from among many attractive possibilities; and be more hard-nosed as program evaluators. That type of courtship should improve our love life with — and perhaps even, science of — primary prevention in mental health. Editor's Note: Emory L. Cowen was honored at the 1979 annual meeting of the American Psychological Association in New York, New York, on September 4, 1979, receiving the Division of Community Psychology Award for Distinguished Contributions to Community Psychology and Community Mental Health. The selection was made by an Awards Committee composed of all the past-Presidents of the Division. Dr. Cowen was introduced by Jack M. Chinsky of the University of Connecticut, and Julian Rappaport of the University of Illinois at Urbana—Champaign.This paper bears some (superficial) resemblance to a talk given at division 27's Distinguished Contribution Award ceremony, during the 87th Annual APA Meetings, New York, N.Y., 9/4/79. This draft is surely lengthier, more convoluted,no more informative, and muchless fun than the spoken version. Conceivably, the main accomplishment of my incessant revisions will prove to be the significant incapacitation of 10 gifted typing fingers attached to the hands of Sharon DeVita — the prime initial victim of my obsessionality. To Sharon, who suffered the indignity and boredom of eternal retypings, my boundless gratitude for her patience, forbearance, and good cheer, well beyond the call of duty.Preparation of this paper was done under support of a grant from the NIMH Experimental and Special Training Branch (MH 14547-02-03), which the author acknowledges with gratitude.
