The Relationship Between Attitudinal Ambivalence and Desire to Quit Smoking Among College Smokers1

Growing evidence shows that attitudes can exist on a bivariate rather than a bipolar plane. This conceptualization provides a more dynamic approach to studying how attitudinal ambivalence (i. e., evaluating an attitude object as both positive and negative) affects smoking‐related behaviors. Based on a sample of 157 college smokers, we obtained preliminary validational support for a smoking‐specific felt attitudinal ambivalence scale. Felt attitudinal ambivalence correlated positively with potential for ambivalence, negative attitudes, and negative as well as positive outcome expectancies related to smoking. Smokers who felt more ambivalent reported a greater desire to quit and were more likely to be contemplators, as defined by the transtheoretical model of behavioral change. In multivariate analyses, felt ambivalence toward smoking predicted desire to quit after controlling for positive and negative attitudes and negative smoking consequences. These results provide promising support for the smoking‐specific felt‐ambivalence scale, and suggest that attitudinal ambivalence should be investigated further as a motivational mechanism to affect smoking cessation.     

Long-term memory in adulthood: An examination of the development of storage and retrieval processes at acquisition and retention

Although it is generally acknowledged that decrements in long-term memory play an important role in the decline of everyday cognitive functioning in adulthood, problems have arisen in localizing the source of these memory deficits. In this article we address three of the methodological and measurement issues that have led to difficulties in interpreting research on adulthood developmental differences in acquisition and long-term retention. Specifically, these issues are stages-of-learning confounds, failures to separate storage and retrieval processes, and failures to separate forgetting from other factors that influence long-term retention tests. A general framework is presented in which each of these problems is dealt with. This model is subsequently applied to an experiment that examined the acquisition and long-term retention of pictures and words in associative memory in both young and old adults. The major findings were that (a) the picture-word manipulation had asymmetrical effects on acquisition and retention, (b) these asymmetries were different for the young and old adults, and (c) the locus (storage/retrieval) of age differences was different at acquisition than at retention. These results strongly suggest that the rules governing acquisition and forgetting are different, not only within age groups, but also across developmental levels in adulthood. More importantly, because the locus of developmental differences was different for acquisition and forgetting, it may be that different mechanisms underly the processing deficits experienced by the elderly when acquiring information than when trying to retain that information over extended periods of time.     

Factors associated with erection in adolescent sex offenders

A majority of adult child molesters report that their deviant interest began prior to the age of 18. This illustrates the need to evaluate adolescents who have molested children. Since self-report of deviant interest is rare in adolescent offenders, psychophysiologic assessment is necessary to help to determine the extent for a deviant interest pattern. The current study was designed to determine what factors are associated with erectile responding to age-inappropriate stimuli in an adolescent sex offender population. Factors studied were (a) admit/deny, (b) history of physical abuse, (c) history of sexual abuse, (d) history of nonsex arrests, and (e) incest/nonincest. The dependent variables were two pedophile indices, a relative measure of deviant to nondeviant arousal. Results indicated that history of sexual abuse was associated with more deviant erectile responding in those adolescents who had molested young boys. The possibility of adolescents modeling their own victimization is discussed.     

Changes in pinch force with bidirectional load forces

The forces used to grasp an object were measured while positive (push) and negative (pull) load forces were applied to the hand under varying frictional conditions. Subjects held between the tips of their thumb and index finger a manipulandum composed of two symmetrically mounted disks. The manipulandum was connected to the stage of an electromagnetic linear motor that generated load forces under computer control. In the first experiment, subjects held the position of the manipulandum constant while the motor generated forces in first the positive and then the negative direction. The motor force at which the manipulandum slipped from the fingers was measured in the second experiment. In both experiments, friction was varied by changing the surface (sandpaper, suede, or plastic) of the manipulandum disks. The pinch forces produced by subjects were linearly related to changes in motor force in both the positive and negative directions, with the slope of this relation varying as a function of the surface properties of the manipulandum. The modulation of pinch force with motor force was influenced, however, by the direction of the load force; higher forces were produced in response to negative load forces. Slip forces varied as a function of pinch force and surface texture; higher forces were associated with materials with lower coefficients of friction. These findings suggest that the friction between the skin and an object being grasped changes as a function of the direction of force that the object applies to the skin, possibly due to the anisotropic nature of glabrous skin, and that this mechanical property contributes to variations in pinch force.     

Factors associated with Borderline pathology in school-age children

The Diagnostic Interview for Borderlines as revised (DIB-R) for use with children and chart review was completed using the records of 54 children, ages 6 to 12 years, who had been admitted to a public psychiatric hospital. Based on the results of the DIB-R, the children were grouped as borderline and nonborderline. The two groups were then compared with regard to 52 independent variables which have historically been associated with the borderline diagnosis. Stepwise logistic regression was used to identify the cluster of diagnostic and independent variables which best discriminated the borderline subjects. Self-destructive behavior, irritable affect, anhedonia, and an externalizing disorder diagnosis at the time of admission accounted for 95.4% of the borderline children. These findings are in contrast to previous studies which have found an assortment of neuropsychological and/or neurological deficits and stressed the importance of a tendency toward psychotic regression on psychological testing as discriminative variables. The authors underscore the idea that borderline pathology may represent a spectrum of disorders and the need for a more specific psychiatric nosology in describing and diagnosing these children.     

Differential thresholds for limb movement measured using adaptive techniques

Differential thresholds for limb movement were measured in 10 subjects, using the transformed up-down procedure. Subjects were required to indicate which of two random displacement perturbations delivered to their forearms had the larger standard deviation (SD). TheSD of the reference signal was fixed for each experimental condition at one of seven values ranging from 0.05 to 3.2 mm. TheSD of the other signal varied depending on the subject’s response. Using this procedure, the differential threshold for limb movement was calculated to be 8%, which is very similar to the thresholds estimated previously for changes in limb position (9%) and force (7%). The sensitivity of the human proprioceptive system to changes in limb displacement was much greater than anticipated, with subjects being able to resolve a 5-μm difference between two perturbations delivered to their arms.     

Preventing harm and promoting ethical discourse in the helping professions: conceptual, research, analytical, and action frameworks

The first in a series of 4 articles, this article provides an overview of the concepts and methods developed by a team of researchers concerned with preventing harm and promoting ethical discourse in the helping professions. In this article we introduce conceptual, research, analytical, and action frameworks employed to promote the centrality of ethical discourse in mental health practice. We employ recursive processes whereby knowledge gained from case studies refines our emerging conceptual model of applied ethics. Our participatory conceptual framework differs markedly from the restrictive model typically used in applied ethics. Our research relies on lived experiences of ethics, while our analytical framework draws attention to the multiple levels and contexts in which ethical dilemmas take place. Finally, our action framework is designed to collaborate with research participants and practitioners in making use of our data and interpretations. We demonstrate how the various frameworks inform each other in an integrative fashion. The article sets the stage for 2 case studies presented in subsequent articles.
