We examined how the Boston Marathon bombings affected threat perception in the Boston community. In a threat perception task, participants attempted to “shoot” armed targets and avoid shooting unarmed targets. Participants viewing images of the bombings accompanied by affectively negative music and text (e.g., “Terror Strikes Boston”) made more false alarms (i.e., more errors “shooting” unarmed targets) compared to participants viewing the same images accompanied by affectively positive music and text (e.g., “Boston Strong”) and participants who did not view bombing images. This difference appears to be driven by decreased sensitivity (i.e., decreased ability to distinguish guns from non-guns) as opposed to a more liberal bias (i.e., favouring the “shoot” response). Additionally, the more strongly affected the participant was by the bombings, the more their sensitivity was reduced in the negatively framed condition, suggesting that this framing was particularly detrimental to the most vulnerable individuals in the affected community. 相似文献

Women with BRCA mutations are inundated with decisions about managing cancer risks and childbearing considerations. Decisions become more complicated when women face disclosing their mutation and risk-reduction options to a romantic partner. This study identifies the concerns and perspectives of male romantic partners regarding these unique decisions. Twenty-five male participants completed an online survey posted to cancer support group message boards. Participants reported relationship changes regarding intimacy levels (n?=?9), attraction (n?=?2), and communication (n?=?22) after mutation disclosure. Participants whose partners had not undergone prophylactic mastectomy (n?=?14) reported concerns regarding sexual relations (n?=?5), post-surgical appearance (n?=?2), post-surgical attraction (n?=?5), and health/lifespan (n?=?9). Participants did not express attitude changes toward childbearing. While mutation disclosure conversations and surgical options are concerns for many BRCA mutation carriers in relationships, male partners share these concerns. Aspects of the relationship may change, but male study participants continued to support their partners. This information can benefit female BRCA mutation carriers, their current or future partners, and genetic counselors working with this particular population. 相似文献

In this paper, we examine how infants’ natural manual and postural activities — what they prefer and do week by week — are related to developmental transitions in reaching skill and its neuromuscular control. Using a dense, longitudinal design, we tracked the manual and postural activities of four infants in a natural, free‐play setting across the first year of life, and related these activities to two transitions in reaching as measured in a structured laboratory setting: the transition to reaching and the transition to stable reaching. Our data indicated that specific advances in the free‐play setting preceded both transitions. Head and upper torso control, the ability to extend the arm and hand to a distant target, and the ability to touch and grasp objects placed nearby were all precursors to the onset of reaching, whereas sitting independently was associated with the transition to stable reaching. We also found important individual variability in when these ‘components’ were in place, indicating that it is the ensemble of components that is essential, not the order in which they develop or the timing of their contribution. These findings suggest that subsequent experimental manipulations should be planned with respect to infants’ individual constellations of skills, rather than looking at only a single precursor to change. 相似文献

Process analysis research methodology was used to examine the interactions between 41 nonprofessional child-aides and 166 primary graders with school maladaptation in 11 urban and suburban schools. Sixty-five percent of the interaction time was spent in play activities, 15% each in conversation and tutoring. Urban schools had more tutoring, while suburban schools emphasized socialization and relation building. Learning disability children had more tutoring time and acting out children more problem conversation. Aides' personal and attitudinal attributes related to process measures. The findings indicate the feasibility and usefulness of process analysis for studying the helping interventions of nonprofessional workers. 相似文献

In the 1967 version of Fishbein's model of the attitude-behaviour relationship a distinction was drawn between personal and social normative beliefs. Personal normative beliefs were later removed from the model on the grounds that they act as an alternative measure of behavioural intention. It is argued that the existing literature does not support this hypothesis and data is presented which indicates that personal normative beliefs are not an alternative measure of behavioural intention. It is argued that personal normative beliefs can be reconceptualized as measuring a person's ideal behavioural intention; a variable which mediates the relationship between attitudes, subjective norms and intentions, Evidence is presented which supports this hypothesis, but it is further demonstrated that an alternative model can be fitted to the present data. It is argued that it is impossible to discriminate between these alternative models on the basis of path analytic techniques, and the implications that this finding has for attitude research are discussed. 相似文献

53 subjects, who scored high on an anxiety check list, were evaluated for their responsiveness to relaxation exercises and biofeedback. Each subject was cognitively stressed prior to the training phase by imagining anxiety-provoking situations. Analysis was done on pertaining/posttraining anxiety scores and physiological parameters (galvanic skin response, differences in finger temperature, and frontalis muscle activity). Subjects given feedback corresponding to that physiological parameter which changed the most when stressed, maximized that feedback more than subjects receiving nonrelevant or no feedback. All groups reported significant reductions in anxiety symptoms. Follow-up analysis 15 mo. later showed 76% of the subjects were still symptom-free for anxiety regardless of type of feedback received. 相似文献

The Operant Package for the Neurosciences (OPN) is a software system that runs on the TRS-80 Model I and Model III and the Apple II+ and Apple lie microcomputers. It is designed to allow a single microcomputer to control behavioral experiments in up to eight different stations, record experimental data, and provide detailed data analysis. Although segments of the program are written in BASIC, allowing users to interact with OPN in a simple English question-and-answer format, the part that provides real-time experimental control is written in Z-80 assembly language. The present report describes in detail assembly language algorithms that we found to facilitate speed of processing and flexibility of control. Particular problems dealt with how to update and change flag variables controlling the reinforcement contingencies and output conditions in each station, as well as how to decide when each station should shift contingencies. The solutions to these problems utilize byte-oriented parallel processing strategies, converting serially organized reference information for each station into a group of working flag bytes that control contingency and output variables for all stations in parallel. 相似文献
