In this paper, we describe software that turns a Macintosh computer into an off-the-shelf tool for experiments on visual search. Our design goals included portability (between members of the Macintosh computer family and between various research settings), user-friendliness (equivalent to Macintosh programming standards), flexibility (to allow replication and extension of important experiments on visual search), and adaptability (very short design-to-data and data-to-analysis turnaround times). We describe how the software meets these goals in three major phases of an experiment: stimulus construction, experimental control, and statistical analysis. We then list several landmark studies of visual search that can be easily designed and extended with the software. Finally, we outline plans for expanding the experimental variations that will be supported in future versions of the software. 相似文献

This paper examines the ethical issues of conflict of interest raised by the burgeoning development of physician involvement in for-profit entrepreneurial activities outside their practice. After documenting the nature and extent of these activities, and their potential for conflicts of interest, the paper assesses the major arguments for and against physicians' referral of patients to facilities they own or in which they invest. The paper concludes that an outright ban on such activity seems ethically warranted. 相似文献

Telehealth research in the field of applied behavior analysis (ABA) has focused on the training and supervision of others to implement various behavior analytic procedures. Current guidelines for practicing telehealth suggest that direct telehealth services may be appropriate for some individuals diagnosed with autism spectrum disorder, but more research is needed. This study evaluated the effects of discrete trial teaching with instructive feedback in a dyad arrangement delivered directly via telehealth to teach tact relations to 6 children diagnosed with autism spectrum disorder. All participants and the experimenter were located in different physical locations. All participants learned their primary and secondary targets, and 5 of the participants acquired the observational primary and secondary targets without direct teaching. Areas of future research and clinical implications are discussed in the context of telehealth service delivery. 相似文献

In none of the deception studies that used drawings to date, was the effect of sketching on both speech content and drawing content examined, making it unclear what the full potential is of the use of drawings as a lie detection tool. A total of 122 truth tellers and liars took part in the study who did or did not sketch while narrating their allegedly experienced event. We formulated hypotheses about the total amount of information and number of complications reported and about various features of the drawings. Participants in the Sketch-present condition provided more information than participants in the Sketch-absent condition, and truth tellers reported more details than liars, but only in the Sketch-present condition. In contrast to previous research, no Veracity differences occurred regarding the content of the drawings, perhaps because sketching was introduced as a tool that facilitated verbal recall and not as a stand-alone tool. 相似文献

Loneliness is a significant public health issue that affects young adults. This investigation drew from interpersonal acceptance-rejection theory to understand how remembrances of parental rejection contributed to psychological maladjustment and loneliness in Bangladeshi college students (N = 300; 50% female). Students reported their remembrances of mothers' and fathers' acceptance-rejection, their current psychological maladjustment, and loneliness. Remembrances of rejection by parents in childhood were associated with psychological maladjustment (hostility/aggression, negative self-esteem, negative self-adequacy, emotional unresponsiveness, emotional instability, and negative worldview) for young adult men and women. Psychological maladjustment, in turn, was associated with feelings of loneliness in young adulthood for young men, but not women. Remembrances of parental rejection were also associated with greater hostility and aggression over and above general psychological functioning among both men and women. Findings are discussed in the context of different social and structural features of young adulthood for women and men in Bangladesh. 相似文献

Abstract Although unprecedented in scope and beyond all our life experiences, sweeping social distancing measures are not without historical precedent. Historically, racism, stigma, and discrimination resulted in grossly inequitable application of disease containment measures. But history also provides examples in which broad measures enjoyed remarkable public support. When it comes to COVID-19, blame and division continue to shape containment responses. But the COVID-19 pandemic also resonates with moments in which there was broad social support for containment precisely because lockdowns or stay at home orders are, on the surface, remarkably equitable. Yet even in a context in which a majority of Americans support social distancing, small but coordinated conservative groups are challenging social distancing as a matter of individual rights. In sharp contrast, vulnerable populations, who bear the heaviest burden of disease, have claimed a right to social distancing as a matter of protection. 相似文献

Much coping research has been conducted comparing members of different ethnic groups using discrete racial classifications. However, the past two decades have seen the construct of ethnicity evolve into a complex variable that must be assessed in a more comprehensive way. This study explored how ethnicity, a discrete variable, and the continuous variables of a person's ethnic identity and self-construal contribute to the use of particular coping strategies across various situations. One hundred twelve seventh graders (67 African Americans and 45 Caucasian Americans) from three suburban middle schools completed questionnaires assessing ethnic identity, self-construal, and coping strategies for medical, test, and social criticism stressors. Results supported the hypothesis that ethnicity as a discrete variable is not associated with coping, but that ethnic identity and self-construal are. It was also found that high scores on the ethnic identity and self-construal scales were indicative of more positive psychological adjustment. Implications for future research and methodological considerations are discussed. 相似文献
