RULES OF EVIDENCE:

Abstract— Statistical tests define rules of evidence in psychological science Agreed-upon rules of evidence are needed to discuss what is true Statistics are probability statements about the reliability of associations In public and journalistic debates about psychological topics, the need far statistical rules is evident Anecdotes, intuitions, and sensational and unlikely events often dominate popular discussions Psychological science demands that the probability of events and associations be evaluated by statistical means Understanding of statistical tests can be improved by abandoning the term significance, winch means reliability to psychologists, but in everyday English, means importance. The importance of a result depends on magnitude of association, not on whether the event has a nonzero chance of recurring. Given large samples and multiple measures, statistical tests are used too often to draw misleading conclusions about the importance of research results. Better uses of statistics would focus on the magnitude of effects and error estimates     

INCIDENTAL LANGUAGE LEARNING:

Abstract —Two experiments investigated the performance of first-grade children and adults on an incidental language-learning task. Learning entailed word segmentation from continuous speech, an initial and crucial component of language acquisition. Subjects were briefly exposed to an unsegmented artificial language, presented auditorily, in which the only cues to word boundaries were the transitional probabilities between syllables. Subjects were not told that they were listening to a language, or even to listen at all; rather, they were engaged in a cover task of creating computer illustrations. Both adults and children learned the words of the language. Moreover, the children performed as well as the adults. These data suggest that a statistical learning mechanism (transitional probability computation) is able to operate incidentally and, surprisingly, as well in children as in adults.     

Characteristics of the System of Production of History-of-Psychology Literature, 1975–1986

We used Psychological Abstracts to identify a large international sample of history-of-psychology literature that was published from 1975 through 1986. Information was obtained on such producer characteristics as: The language in which each publication was written; the country (or American state) from which it originated; and authorship gender and number. Differences in productivity were examined as a function of these variables and their combinations; comparisons were made with a random sample of psychological literature and with previously published findings regarding publication in psychology. Conclusions were drawn regarding the history of psychology considered as a literature-producing enterprise.     

Alcoholism treatment and marriage and family therapists: An empirical study

This article reports on results of a mail questionnaire study conducted among 257 members of the American Association for Marriage and Family Therapy (132 respondents, response rate of 51%) on their attitudes toward alcoholism issues (acceptance of alcoholism as a disease, treatment philosophies used with clients and/or families, and acceptance and use of Alcoholics Anonymous as a resource). Results indicated that 69% of respondents (as compared with 42% formerly) considered alcoholism a disease after MFT education. A combination of individual, family therapy, and AA (81.1%); family therapy (66.7%); and AA only (60.6%) were most often used. Controlled use of alcohol by clients in treatment was believed to be unethical by 43.2%, legal by 39.4% and ineffective by 54.5%.     

Effects of setting and number of observations on generalizability of parent-child interactions in childhood obesity treatment

The generalizability of behaviors across observational conditions is a critical issue in behavioral assessment. Generalizability theory was used to examine two aspects of audio recorded parent-child interactions recorded over 6 days of home measurement and 1 day of laboratory measurement in a behavioral treatment program for childhood obesity. Families audiotaped parent-child home meetings during which they reviewed self-monitored diet and exercise records that were coded for the following types of interactions: praise statements, negative statements, prompts for new behaviors, and statements promoting problem solving. A similar meeting was audiotaped in our laboratory. The first question explored was the number of measurements needed to generalize to the universe of the six home measures. Results showed an increase in generalizability over measurements for each behavioral category. Using generalizability coefficients of .60 or more, praise, negative comments and prompts, respectively, could be reliably observed based on 1, 4, or 4 days of measurement. Second, the effects of setting (laboratory versus home) were assessed for 1 day of measurement in each environment. Again using generalizability coefficients of .60, generalizability analysis showed that the lab setting could not be generalized to the home setting based on 1 day of measurement, with generalizability coefficients ranging from .27 for negative comments to .57 for praise. Results suggest that 4 days of behavioral assessment in the home can be used to establish generalizable data for all the dependent measures studied. However, generalizability coefficients suggested that 1 day of laboratory measurement was not adequate to generalize to typical home behavior.This research was supported in part by Grant NIH HD 23713 awarded to the third author.     

The relation between gender schemas and adults' recall of stereotyped and counterstereotyped televised information

The relation between adults' gender-related personality characteristics and memory for gender-stereotyped and counterstereotyped televised information was examined. Eighty middle-class undergraduates, equally divided by gender (92% Caucasian and 8% minority groups), viewed a television program that presented two plots: one was traditionally gender-stereotyped and the other was counterstereotyped. Three weeks after viewing, students answered questions assessing their recall of stereotyped and counterstereotyped information that had been presented in the television program. Masculinity and femininity scores were also assessed. Results indicated that gender aschematic adults recalled more counterstereotypical information than did gender schematic adults. Results were interpreted within an information processing model.The authors thank the students of Georgetown University who participated in this research.     

Differential effects of massage and heelstick procedures on transcutaneous oxygen tension in preterm neonates

The present study investigated the differential effects of heelsticks and tactile-kinesthetic massage on transcutaneous oxygen tension (TcPO₂) in preterm infants. The sample was comprised of 37 stabilized preterm neonates from the Neonatal Intensive Care Unit. During the heelstick procedure, TcPO₂ significantly declined an average of 14 mmHg. When compared to the tactile-kinesthetic massage, TcPO₂ levels during the heelstick (M = 39.8) were significantly lower than during the stimulation (M = 72.8). Mean TcPO₂ levels remained clinically safe during the four massage sessions evaluated. The TcPO₂ levels during kinesthetic stimulation were somewhat more varied, and movement and pressurization of the TcPO₂ electrode were investigated as possible artifactual explanations for this phenomenon. Overall, the findings indicate that social forms of touch such as tactile-kinesthetic massage do not appear to have a medically compromising effect on TcPO₂ in the preterm neonate. These findings are evaluated in relation to the “minimal touch” policy, and implications for future handling of the stabilized preterm neonate are discussed.     

Countertransference and the developing family therapist: Treatment and supervision issues

All therapists experience reactions toward clients, which have traditionally been called countertransference. Such reactions toward families pose special issues for beginning and developing family therapists. This clinically based and clinically oriented article describes some of the reactions, clues pointing to their existence, and indicates some of the ways beginning and developing family therapists and their supervisors and consultants can deal constructively with these reactions.
