Power Spectral Density Analysis of Lateral Human Standing Sway

A number of investigators have used power spectral density (PSD) analysis to try to identify and quantify various sensory systems which are involved in upright standing. Using PSD analysis, over a frequency range from 0.02-2.5 Hz, the present study examined two trials of lateral sway in each of 80 men. The results showed that little change occurred in PSD values between the first and second trials. Exponential curves were fit to the averaged trials data of each subject. The values of the parameter estimates obtained from the curve-fitting were regressed on the values of various direct, and derived anthropometric variables to try to explain the variance of the parameter estimates in terms of the anthropometrics. The subject’s center of gravity location accounted for no more than 15.8% of the parameter variance, whereas the remaining anthropometrics explained even less. The overall averaged data suggest that three functions (related to visual, vestibular, and proprioceptive processes) may underlie the sway pattern over this frequency range. PSD curves of individuals with a history of high-level athletic activity clearly differed from those of sedentary subjects.     

Do stigma and its psychosocial impact differ between Asian-born Chinese immigrants and Western-born Caucasians with head and neck cancer?

Stigma appears to influence emotional distress and well-being in cancer survivors, but cross-cultural differences have been ignored. Previous studies suggest that stigma may be especially relevant for survivors of Asian origin. However, their study designs (e.g. focused on female cancers, qualitative designs, and an absence of comparison groups) limit the strength of this conclusion. We hypothesized that (1) Asian-born Chinese immigrants (AI) would report more perceived cancer-related stigma than Western-born Caucasians (WBC); and (2) the impact of stigma on emotional distress and well-being would be greater in AI as compared to WBC. Head and neck cancer survivors (n = 118 AI and n = 404 WBC) completed measures of well-being, emotional distress, and a three-item indicator of stigma in structured interviews. The majority of respondents (59%) reported one or more indicators of stigma. Stigma correlated significantly with emotional distress (r = .13, p = .004) and well-being (r = ?.09, p = .032). Contrary to our hypotheses, WBCs and AIs did not differ in reported stigma nor did we detect differences in its psychosocial impact. Stigma exerts a deleterious psychosocial impact on head and neck cancer survivors. It did not differ significantly between AI and WBC survivors.     

Retrieval plus scanning: Does it occur?

In the two experiments reported here, we tested the retrieval-plus-scan model of delayed probe recognition by adding a second probe 2 sec after subjects had responded to the first probe. According to this model, the list items should still be in consciousness from the first probe at the time of the second probe. Consequently, on tests in which the first probe had been tested immediately, we expected to find the same pattern of performance on both first and second probes. On tests in which the first probe came after a filled delay, we expected the first-probe data to show the effects of retrieval and proactive interference. These effects should not be present on the second probe. The results of the first-probe data in both experiments were consistent with the retrieval-plus-scan model. The second-probe data did not fit the model, however. In the first experiment, the second probe on what had been delayed first-probe trials still produced intercept differences, indicating the presence of retrieval. In the second experiment, the effects of proactive interference were still present on the second probe. It is suggested that these results not only invalidate the retrieval-plus-scan model for delayed probe recognition but that they, along with other results, cast doubt on a scanning operation in immediate probe recognition.     

Federal Funds to Train Clinical Psychologists for Work with Underserved Populations: The Bureau of Health Professions Graduate Psychology Education Grants Program

This paper describes the Bureau of Health Professions (BHPr) Graduate Psychology Education program (GPE), which supports projects that train health service psychologists for work with underserved populations. BHPr history and funding criteria are discussed, as are those of BHPr's parent organization, the Health Resources Service Administration. BHPr objectives and methods for support of clinical psychology training parallel those that BHPr has used to support training in other heath professions. The paper also describes three psychology internship training programs in academic medical settings that competed successfully for BHPr GPE funding in 2002. The three training projects differ significantly in training rotation sites, target populations with which trainees work, and the other health care professions that partner with psychology in interdisciplinary training—but they are similar in that each project provides an example of a program that effectively satisfied BHPr criteria for expanding psychology's scope of practice with underserved populations.     

From Standard Scientific Realism and Structural Realism to Best Current Theory Realism

I defend a realist commitment to the truth of our most empirically successful current scientific theories—on the ground that it provides the best explanation of their success and the success of their falsified predecessors. I argue that this Best Current Theory Realism (BCTR) is superior to preservative realism (PR) and the structural realism (SR). I show that PR and SR rest on the implausible assumption that the success of outdated theories requires the realist to hold that these theories possessed truthful components. PR is undone by the fact that past theories succeeded even though their ontological claims about unobservables are false. SR backpeddles to argue that the realist is only committed to the truth about the structure of relations implied by the outdated theory, in order to explain its success. I argue that the structural component of theories is too bare-bones thin to explain the predictive/explanatory success of outdated theories. I conclude that BCTR can meet these objections to PR and SR, and also overcome the pessimistic meta-induction.     

Politics perceptions as moderator of the political skill – job performance relationship: A two-study, cross-national, constructive replication

We developed a two-study, cross-national, constructive replication to examine the role of organizational politics perceptions as a contextual moderator of the political skill – job performance relationship. Specifically, we hypothesized that high levels of political skill would demonstrate its strongest positive effects on job performance when politics perceptions were perceived as low. Conversely, we hypothesized that political skill would demonstrate no relationship with job performance under conditions of high politics perceptions. Across studies conducted both in the United States and Greece, the hypothesis received strong support. In settings characterized by lower perceived politics, high levels of political skill predicted significant increases in job performance, whereas these effects were attenuated in environments characterized by high perceived politics. Contributions and implications of this research, strengths and limitations, and directions for future study are discussed.     

Talking about visually perceived events: Communication effects on eyewitness memory

Communicators' tuning of a message about a social target to their audience's evaluation can shape their representation of the target. This audience‐tuning effect has been demonstrated with ambiguous text passages as input material. We examined whether the effect also occurs when communicators learn about the target's behaviours from visual (nonverbal) input material. In Experiment 1, participants watched a soundless video depicting ambiguous behaviours of a target, described the video to an audience who liked (vs. disliked) the target, and subsequently recalled the video. Both message and recall were biased towards the audience's judgement. In Experiment 2, the video depicted a forensically relevant event, specifically ambiguous behaviours of two persons involved in a bar brawl. Participants tuned their event retellings to their audience's responsibility judgement and remembered the event accordingly. In both experiments, the effect of the audience's judgement on recall was statistically mediated by the extent to which the message was tuned to the audience. The more participants experienced a shared reality with their audience the stronger was the message‐recall correlation (Experiment 2). We conclude that the audience‐tuning effect for visually perceived information depends on the communicators' creation of a shared reality with their audience.

Psychological impact of illness intrusiveness in epilepsy - comparison of treatments

Chronic illnesses are associated with multiple stressors that compromise quality of life (QOL). Implicit in many of these is the concept of illness intrusiveness, the disruption of lifestyles and activities attributable to constraints imposed by chronic disease and its treatment. This study tested the illness intrusiveness theoretical framework in epilepsy and compared the impact of pharmacological and surgical treatments on illness intrusiveness and QOL. Cross-sectional data compared three epilepsy groups (N = 145): (a) 40 patients admitted for presurgical evaluation to an Epilepsy Monitoring Unit; (b) 52 patients treated pharmacologically; and (c) 53 post-surgical patients. Illness intrusiveness differed significantly across epilepsy patients with the differences primarily related to seizure control. Illness intrusiveness varied inversely with seizure control (p < .05). Seizure freedom, whether achieved by surgical or pharmacological treatments, was associated with maximal reduction of illness intrusiveness. Increased illness intrusiveness correlated significantly with decreased QOL and increased depressive symptoms. Perceived control over diverse life domains correlated positively with QOL and psychosocial outcomes. Path analysis supported the validity of the illness intrusiveness theoretical framework in epilepsy. Illness intrusiveness is an important determinant of the psychosocial impact of epilepsy and its treatment. Effective pharmacological or surgical treatment may reduce illness intrusiveness in epilepsy. Findings also offer encouragement that QOL in epilepsy, as in other chronic conditions, may be enhanced by multidisciplinary bio-psychosocial efforts. Health care providers should consider multifaceted interventions to reduce illness intrusiveness and, thereby, improve QOL.     

Shared Reality: Experiencing Commonality With Others' Inner States About the World

ABSTRACT— Humans have a fundamental need to experience a shared reality with others. We present a new conceptualization of shared reality based on four conditions. We posit (a) that shared reality involves a (subjectively perceived) commonality of individuals' inner states (not just observable behaviors); (b) that shared reality is about some target referent; (c) that for a shared reality to occur, the commonality of inner states must be appropriately motivated; and (d) that shared reality involves the experience of a successful connection to other people's inner states. In reviewing relevant evidence, we emphasize research on the saying-is-believing effect , which illustrates the creation of shared reality in interpersonal communication. We discuss why shared reality provides a better explanation of the findings from saying-is-believing studies than do other formulations. Finally, we examine relations between our conceptualization of shared reality and related constructs (including empathy, perspective taking, theory of mind, common ground, embodied synchrony, and socially distributed knowledge) and indicate how our approach may promote a comprehensive and differentiated understanding of social-sharing phenomena.
