A Q-methodological study of lesbian identities

A Q-methodological study of lesbian identities is reported, which reveals substantive factors representing identity account clusters explicated as the ‘Personal Fulfilment’ identity, the ‘Special Person’ identity, the ‘Individualistic’ identity, the ‘Radical Feminist’ identity, and the ‘Traditional’ identity. These identities are supported and illuminated by the use of accounts given by the same respondents in tape-recorded interviews and are related to the rather limited previous literature in the field. Further developments in the investigation of accounts of identity are proposed.     

Frames of reference in preschoolers’ perception of motion

Experiments 1 and 2 established children’s (mean age 3 years, 7 months) subject-relative and object-relative motion thresholds at 1°31.37′/sec and 1°9.33′/sec, respectively, speeds well above those found for adults. Experiment 3 established that preschoolers, like adults, attribute object-relative motion to the smaller of two objects, with the inducing properties of the larger stimulus greatest when it is surrounding rather than adjacent to a smaller stimulus. The inducing advantage of surroundedness was equivalent for a single-element square frame and a multielement six-dot frame.     

The effects of violence on infants and young children: international perspectives on prevention

People become subject to political and social violence when governments fail to give priority to basic health care or education. Attempts to meet foreign obligations also produce severe economic recessions which further impede efforts to improve the general quality of life of disadvantaged populations. Since multiple factors contribute to violence, a multidisciplinary approach is best suited to address the problem. For example, poverty and its associated risks are linked to violence, but living in poverty does not necessarily engender violence. Living in poverty may, however, fuel high rates of child mortality, illiteracy, malnutrition, excessive population growth, street children, and familial disintegration. An integrated action program was developed in Brazil for at-risk individuals and their families based upon the idea of building and reinforcing family ties and intergenerational togetherness. Undernourished infants, street children, the handicapped, women subjected to violence, and neglected senior citizens received special interventions in the program described in the text.     

Evaluating pediatric psychology consultation services in a medical setting: An example

We examined the nature of referrals to a health center-based pediatric psychology service from 1990 to 1993 and assessed the satisfaction of health professionals with these services. Archival evaluation of 1467 records showed that over half of the consultation requests came from general pediatrics, pediatric neurology, and surgical services and that 70% of the psychological services were delivered on an outpatient basis. The most frequent referrals were for cognitive/neuropsychological evaluation and externalizing behavior problems. Pediatric psychology trainees were involved in 94% of the consultations. Survey of health professionals (n = 143) indicated very high overall satisfaction with the quality of services delivered. Presenting problems yielding the greatest likelihood for future consultation requests were behavior problems, child abuse, coping with illness, and depression/suicide. Results are discussed in the context of previous evaluations of pediatric psychology services and recommendations for future evaluation research.     

Visual comparison processes: Identity and similarity decisions

In the first experiment, in which two successively presented free-form visual patterns varied in their similarity to each other, subjects had to decide, in one condition, if the patterns were “identical” and in two other conditions if the patterns were “similar.” Qualitative individual differences in the effect of similarity on the time required to make a decision were found in the “identity” condition, and these differences interacted with the “similarity” conditions. The individual differences and the experimental effects are interpreted in terms of a two-process model of the visual comparison process—a holistic matching process that is sometimes accompanied by an analytic difference detection process. In the second experiment, the same subjects repeatedly categorized subsets of the free-form visual patterns on the basis of similarity. There appeared to be no individual differences in the subjects’ perceptions of similarity, but subjects’ perceptions did differ from the assumptions made by the experimenters when they established the response criteria for the first experiment.     

Deception research involving children: ethical practices and paradoxes

This commentary draws on the thoughtful contemplation and innovative procedures described in the special section articles as well as current professional codes and federal regulations to highlight ethical practices and paradoxes of deception research involving children. The discussion is organized around 4 key decision points for the conduct of responsible deception research involving children: (a) evaluating the scientific validity and social value of deception research within the context of alternative methodologies, (b) avoiding and minimizing experimental risk, (c) the use of child assent procedures as questionable ethical safeguards, and (d) debriefing as both remedy and risk.     

A Comparison of Three Methods of Teaching Skin Self-Examinations

Skin self-examinations are essential for the early identification and treatment of skin cancers. However, little is known about the most effective methods for teaching skin cancer detection and skin self-examination. This study compared three skin cancer education methods that are commonly used in the primary care setting: viewing a videotape, reading brochures, and one-on-one instruction from a nurse practitioner. One hundred forty-three young adults were randomly assigned to one of the four conditions (educational intervention or wait list) and completed measures of skin cancer knowledge, ability to visually discriminate cancerous versus noncancerous skin growths, and behavioral ability to perform a skin self-examination immediately (Time 1) and 3 weeks (Time 2) after the educational intervention. Results showed that participants across all educational interventions had significantly higher skin cancer knowledge compared to those in the wait-list control group, and these knowledge scores were maintained for 3 weeks. Participants in the brochure condition scored significantly higher than participants in all other conditions on an observational measure of skin self-examination. Demographic variables, such as gender and ethnicity, were not found to be related to performance on any of the dependent measures. These findings provide preliminary evidence that knowledge of skin cancer may be enhanced through a variety of educational techniques and that written materials (e.g., brochures) may represent the minimal intervention level necessary for teaching adults how to perform thorough skin self-examinations.     

Stimulus disparity and punisher control of human signal-detection performance

The present experiment examined the effects of varying stimulus disparity and relative punisher frequencies on signal detection by humans. Participants were placed into one of two groups. Group 3 participants were presented with 1:3 and 3:1 punisher frequency ratios, while Group 11 participants were presented with 1:11 and 11:1 punisher frequency ratios. For both groups, stimulus disparity was varied across three levels (low, medium, high) for each punisher ratio. In all conditions, correct responses were intermittently reinforced (1:1 reinforcer frequency ratio). Participants were mostly biased away from the more punished alternative, with more extreme response biases found for Group 11 participants compared to Group 3. For both groups, estimates of discriminability increased systematically across the three disparity levels and were unaffected by the punisher ratios. Likewise, estimates of response bias and sensitivity to the punisher ratios were unaffected by changes in discriminability, supporting the assumption of parameter invariance in the Davison and Tustin (1978) model of signal detection. Overall, the present experiment found no relation between stimulus control and punisher control, and provided further evidence for similar but opposite effects of punishers to reinforcers in signal-detection procedures.
