The disappearance of real and subjective contours

The disappearance characteristics of luminous designs were studied in three experiments. The stimuli were geometric forms set off by either real or subjective contours. Subjective-contour forms fragmented more often and in a manner qualitatively different from that of forms created with real contours. Previewing a real-contour form increased the subsequent fragmentation of that form, but no adaptation effects were noted among forms created with subjective contours, and there was no cross-contour adaptation. These results are interpreted as inconsistent with the position that subjective contours result from the partial activation of feature-analyzer mechanisms in the visual system.     

THE FORMATION OF FRIENDSHIPS AMONG ZAMBIAN UNIVERSITY STUDENTS

Les recherches aux Etats-Unis ont fait apparaître une relation entre distance psychologique et distance physique. A L'Université de Zambie, en raison des particularités géographiques du campus et de la complexité sociale du corps étudiant, on peut pousser plus loin L'étude de la relation entre espace et liens sociaux. L'analyse des schémas d'amitié entre étudiants montre que les relations spatiales ont un certain rôle dans L'établissement des liens interpersonnels, mais que les facteurs sociaux et psychologiques sont plus déterminants. Il apparaît comme on pouvait s'y attendre, que dans la plupart des cas, L'amitié s'établit avec un partenaire de même sexe, de même âge et surtout de la même école d'origine. Les facteurs linguistiques ou tribaux sont sans importance: ils semblent dépassés par un sentiment grandissant d'appartenance à une élite. Les étudiants zambiens ont un comportement insulaire bien que non chauvin: ils ont peu d'amis parmi les étudiants qui viennent d'autres parties d'Afrique et aucun parmi les quelques étudiants blancs. La religion joue un grand rôle, ce qui n'a rien d'étonnant dans une société où L'influence des écoles et de la morale des missions n'a pas encore disparu. Les étudiants zambiens sont aussi individualistes dans le choix de leurs amis que les étudiants de n'importe quel autre pays. Ils semblent souvent plus solitaires et avoir plus grand besoin d'un confident que les étudiants anglais et suf-africains.     

Extension cues in open and closed figures

Subjects were shown line drawings of figures differing in degree of closure, and asked what the drawings most looked like. Responses were dichotomized into “upright” (e.g. beaker) and “extended” (e.g. runway). Although, overall, about twice as many upright as extended responses were given, relatively open figures yielded about twice as many extended responses as did relatively closed figures. Converging lines as such appeared an unexpectedly weak cue for extension, and horizontal discontinuity in a drawing seemed more suggestive of extension than did vertical discontinuity. Reclassifying the responses as two- or three-dimensional showed that although two-dimensional responses were less common overall, they were three times as common in relatively closed drawings. Predictions are made relating the findings to standard visual illusions.     

Effects of modeling and videotape feedback with knowledge of results on motor performance

On the basis of social learning theory it can be hypothesized that information acquired through model observation can provide as rich a basis for a cognitive representation as that acquired by means of the usual KR procedure. A source of external information similar to that of model observation is videotape feedback (VTFB). Therefore, it was the purpose of this study to test the potency of these two sources of information with KR. The design was a 4 (groups) × 10 (blocks) factorial ANOVA with repeated measures on the last factor. Both immediate transfer and 48-hr retention effects were assessed. The immediate transfer analysis indicated a significant main effect for group. This effect appeared to be due to the poor performance of the VTFB group. The same effect approached significance after the 48-hr retention. Subsequent variance analysis indicated significant differences between transfer and retention within all conditions except modeling.     

Clinician-Stakeholders’ Perspectives on Using Patient Portals to Return Lynch Syndrome Screening Results

Test results for genetic conditions, such as Lynch Syndrome (LS), have traditionally been returned by genetic counselors or other providers who can explain results implications and provide psychosocial support. Returning genetic results through an Electronic Health Record’s patient portal may increase the efficiency of returning results and could activate patient follow-up; however, stakeholder input is necessary to determine acceptability and appropriate implementation for LS. Twenty interviews were conducted with clinicians from six specialties involved in LS screening that represent a range of settings. Data were analyzed using directed content analysis and thematic analysis across content categories. Participants felt that patient portals could supplement personal calls, but the potential sensitive nature of LS screening results indicated the need for caution. Others felt that LS results could be returned through portals if there were clear explanations of the result, reputable additional information available within the portal, urging follow up confirmatory testing, and a referral to a genetics specialist. Patient portals were seen as helpful for prompting patient follow-up and providing resources to notify at-risk family members. There is potential for patient portals to return LS screening and other genetic results, however we raise several issues to resolve before implementation is warranted.     

De l’opportunité d’une nouvelle loi sur la fin de vie ?

This paper deals with the end of life issue. It advocates for putting the legislation about end of life a part from bioethics laws and addresses some legal problems.     

Prevalence of Types of Perpetration: Gender and Patterns of Intimate Partner Violence Within a Prison Sample in Singapore

It has been reported in Western research on intimate partner violence (IPV) that there are similar rates between males and females (Filbert, 2010). The objective of this study was to compare male and female prisoners from Singapore on rates of IPV as well as the Johnson (2006) types of IPV. Women (n = 75) self-reported higher rates of physical IPV perpetration in the past year (64.0%) than (n = 75) did men (46.1%). Women reported similar rates of IPV for themselves and their partners in the past year (64.0%), while men reported slightly more physical IPV for themselves (46.1%) than they did for their female partners (41.3%). In line with Johnson (2006), rates of intimate terrorism were calculated between 5% and 7% for themselves and their partners, with little variation due to gender. Violent resistance (VR) was calculated at between 2.1% and 7%, with more female than male VR reported for women. Much higher rates of situational couple violence was calculated for both males and females, ranging from 53.3% to 66.7% in the past year, while mutual violent control was significantly lower, ranging from between 14.8% to 20.0%, with data being discussed in relation to patriarchal and family violence perspectives. We concluded that the rates of IPV between males and females were very similar as were the types of IPV. Further research with other cultures should be encouraged for comparison with Western samples.     

Predictors of adherence to aerobic exercise in rectal cancer patients during and after neoadjuvant chemoradiotherapy

This pilot study explored predictors of adherence to exercise during and after neoadjuvant chemoradiotherapy (NACRT) in rectal cancer patients. Eighteen rectal cancer patients were prescribed three supervised aerobic exercise sessions/week during NACRT followed by ≥150 min/week of unsupervised aerobic exercise after NACRT. Although not statistically significant, adherence to supervised exercise during NACRT was meaningfully better for patients who were women (d = .82; P = .12), younger (d = ?.62; P = .30), married (d = .62; P = .42), with better mental health (r = .32; P = .21), fewer diarrhea symptoms (r = .48; P = .052), and higher anticipated enjoyment (r = .31; P = .23), support (r = .32; P = .22), and motivation (r = .31; P = .23). After NACRT, adherence was significantly better for patients who reported worse mental health (r = ?.56; P = .046) and meaningfully better for patients who were women (d = .54; P = .38), better educated (d = .77; P = .22), had no comorbidities (d = ?.63; P = .17), and exercised at baseline (d = 1.05; P = .12). Demographics, tumor side effects, and motivational variables may predict adherence to exercise during and after NACRT.
