Lying to insurance companies: the desire to deceive among physicians and the public

This study examines the public's and physicians' willingness to support deception of insurance companies in order to obtain necessary healthcare services and how this support varies based on perceptions of physicians' time pressures. Based on surveys of 700 prospective jurors and 1617 physicians, the public was more than twice as likely as physicians to sanction deception (26%versus 11%) and half as likely to believe that physicians have adequate time to appeal coverage decisions (22%versus 59%). The odds of public support for deception compared to that of physicians rose from 2.48 to 4.64 after controlling for differences in time perception. These findings highlight the ethical challenge facing physicians and patients in balancing patient advocacy with honesty in the setting of limited societal resources.     

Functional analysis and treatment of self-injurious behavior in young children a summary of 30 cases

The assessment and treatment of self-injurious behavior (SIB) has received much attention in the literature; however, few studies have focused on early intervention for this behavior. In the current study, functional analyses with developmentally appropriate modifications were conducted in an outpatient clinic with 30 children (aged 10 months to 4 years 11 months) to assess SIB and problem behavior in its early stages. The reported mean age of SIB onset was 17 months, and head banging was the most prevalent topography. Functional analyses identified sources of reinforcement for SIB in 62.1% of cases; with the inclusion of all forms of problem behavior, sources of reinforcement were identified for 87.5% of cases. Function-based treatments were developed for 24 cases, with functional communication training prescribed most often (70.8% of cases). Implications of these findings for the development of early intervention programs for SIB are discussed.     

Knowing in advance: the impact of prior event information on memory and event knowledge

We examined the influence of newly acquired information on children's memory and general representation of a personally experienced event. Thirty-five children between the ages of 5 and 7 years participated in the novel event (Visiting the Pirate). The day before participating, children were: (1) provided with new information specific to the up-coming event; (2) engaged in a discussion generally related to the event topic based on existing knowledge; or (3) discussed an unrelated topic. Advance information specific to the event led to better recall and, in particular, to better integration of the experience into a general event representation both soon after the event and at a follow-up interview 4 months later, whereas general discussion of the topic without the event specific information neither enhanced memory reports nor facilitated the integration of event information. Providing information in advance can have significant effects on memory and knowledge acquisition although many variables, including those relating to the specific content of the information, will affect this relation.     

Relationship of depression and anxiety to cancer patients' medical decision-making

The purpose of this study was to examine the relation of depression and anxiety to cancer patients' medical decision-making. Participants were 79 rural and urban cancer patients undergoing chemotherapy. The four decisional styles of the Decisional Processing Model were the independent variables. Dependent variables were anxiety and depression, measured by Spielberger's State-Trait Anxiety and the Center for Disease Control Depression Scale, respectively. Consistent with the Decisional Processing Model, analysis suggested that patients make medical decisions by information seeking, information processing, advice following, or ruminating. Decisional style did not vary according to type or stage of cancer, prognosis, time elapsed since initial diagnosis, or whether cancer was initial or recurrent. Decisional style did not systematically vary with depression and anxiety suggesting how a person makes decisions is a stable personality trait. Thus, decision-making may follow a cognitive schema. It is likely that patients' decisional styles help to manage anxiety and depression when confronted with life-threatening illness. Implications for informed consent and patients' involvement in decision-making are discussed.     

Age constraints on first versus second language acquisition: evidence for linguistic plasticity and epigenesis

Does age constrain the outcome of all language acquisition equally regardless of whether the language is a first or second one? To test this hypothesis, the English grammatical abilities of deaf and hearing adults who either did or did not have linguistic experience (spoken or signed) during early childhood were investigated with two tasks, timed grammatical judgement and untimed sentence to picture matching. Findings showed that adults who acquired a language in early life performed at near-native levels on a second language regardless of whether they were hearing or deaf or whether the early language was spoken or signed. By contrast, deaf adults who experienced little or no accessible language in early life performed poorly. These results indicate that the onset of language acquisition in early human development dramatically alters the capacity to learn language throughout life, independent of the sensory-motor form of the early experience.     

Values and behavior: strength and structure of relations

Three studies address unresolved issues in value-behavior relations. Does the full range of different values relate to common, recurrent behaviors? Which values relate more strongly to behavior than others? Do relations among different values and behaviors exhibit a meaningful overall structure? If so, how to explain this? We find that stimulation and tradition values relate strongly to the behaviors that express them; hedonism, power, universalism, and self-direction values relate moderately; and security, conformity, achievement, and benevolence values relate only marginally. Additional findings suggest that these differences in value-behavior relations may stem from normative pressures to perform certain behaviors. Such findings imply that values motivate behavior, but the relation between values and behaviors is partly obscured by norms. Relations among behaviors, among values, and jointly among values and behavior exhibit a similar structure. The motivational conflicts and congruities postulated by the theory of values can account for this shared structure.     

Modeling unipolar depression as a chaotic process

This study inspected the deterministic structure of unipolar depression. Two women self-monitored sadness hourly 10 times a day for 6 months. One woman had a recurrent history of unipolar depression, and the other did not. Data were analyzed by visual inspection, examination of the Fourier transforms of the time plots, and the correlation dimension. Results suggested that in addition to a strong periodic component that existed only within the depressed subject's mood time series, a low-dimensional chaotic process might have been operating. In the nondepressed control subject, no such periodicity or process could be identified. The findings support maladaptive deterministic theories of mood disorders and have implications for the assessment of unipolar depression.     

I don't think that's what really happened: the effect of cross-examination on the accuracy of children's reports

In the courtroom, child witnesses must undergo cross-examination. Prior research has shown that children change their original testimony under cross-examination, but the effect of these changes on the accuracy of children's testimony is unknown. The authors examined the effect of cross-examination on the accuracy of 5- and 6-year-old children's (N=46) reports of a contrived event. Consistent with prior research, children made changes to their original responses during cross-examination. Furthermore, these changes occurred irrespective of original accuracy. Finally, prior exposure to misleading information did not affect children's responses to cross-examination. Even children with no prior exposure to misinformation altered their original responses, decreasing their ultimate levels of accuracy. These findings demonstrate that cross-examination style questioning is inappropriate for young children.     

Physical imagery: kinematic versus dynamic models.

Physical imagery occurs when people imagine one object causing a change to a second object. To make inferences through physical imagery, people must represent information that coordinates the interactions among the imagined objects. The current research contrasts two proposals for how this coordinating information is realized in physical imagery. In the traditional kinematic formulation, imagery transformations are coordinated by geometric information in analog spatial representations. In the dynamic formulation, transformations may also be regulated by analog representations of force and resistance. Four experiments support the dynamic formulation. They show, for example, that without making changes to the spatial properties of a problem, dynamic perceptual information (e.g., torque) and beliefs about physical properties (e. g., viscosity) affect the inferences that people draw through imagery. The studies suggest that physical imagery is not so much an analog of visual perception as it is an analog of physical action. A simple model that represents force as a rate helps explain why inferences can emerge through imagined actions even though people may not know the answer explicitly. It also explains how and when perception, beliefs, and learning can influence physical imagery.     

A Question of Two Answers: Difference and Determination in Barth and von Balthasar

This essay uses the motif of 'the woman as answer' in Barth and von Balthasar to explore aspects of their accounts of sexual difference in relation to ontological and trinitarian difference. In both cases the motif is shown to be problematic for reasons which become apparent in christology. Barth's characterisation of woman as the 'sufficient answer' to the prior 'question' posed by man indicates a tendency towards the elision of difference in his anthropology, which is reflected in the nonsexuality of Christ - the 'true Man' Ð and in aspects of his trinitarian theology. Von Balthasar's 'double answer' of woman to man moves beyond viewing sexual difference as the locus of man's self-completion, but the overdetermination of 'woman' in his mariology undermines this. The pneumatology of von Balthasar's 'Spiritus Creator' suggests possibilities for the development of a christologically-focused anthropology which maintains difference.
