Blind readers were tested using two methods of reading text displayed by an Apple microcomputer. The first method employed an Optacon system, a device that displays tactile representations of single characters, and the second used an interactive single electronic braille cell that displayed grade 1 braille characters. The results demonstrated no difference in accuracy or reading speed between these two methods. Thus, the serial presentation of braille characters at a single position appears to be a viable method of information transfer between computers and braille readers. 相似文献
The proposal that peripheral visual changes (cues) tend to summon attention automatically was tested by studying the effect
of peripheral cueing on simple detection latency. Delay between cue onset and target onset, the contingent relationship between
cue location and target location, and instructions to subjects were manipulated. Results showed that a peripheral display
change could capture attention even when the target was far more likely to appear at an uncued location. When subjects were
explicitly informed that targets were likely to appear away from the cued location they were able to suppress this effect,
but were unable completely to reverse it by rapidly orienting attention towards the uncued side. Hence the process appears
to be automatic in the sense that it occurs unless there are explicit instructions to the contrary. With explicit instructions
the processing operation can be suppressed, but not completely reversed.

This article summarizes the results of an evaluation of mediation services in three court-based programs. Among the issues considered are client evaluations of the mediation experience and their assessments of immediate and long-term effects. Two comparison groups are utilized: parents who contested custody without the offer of court-based mediation and parents who divorced but did not contest custody. Results of the research indicate that mediation provides a valuable compliment to the existing domestic relations court processes. Mediation enjoys high user satisfaction and helps promote compliance with the agreement, a sense of equity, and continued cooperation. Thus, while the expectations of the process should not be overstated, it appears that even a brief mediation with a troubled population can produce modest but positive benefits. 相似文献
The empirical research pertaining to the effectiveness of telephone counseling and referral systems personnel was critically reviewed. The assessment was organized according to several evaluation strategies that researchers have utilized to evaluate effectiveness. These strategies included, for example, client self-reports, client "shows" versus "no-shows" following referral, data pertaining to suicide rates, counselor ratings of personal effectiveness, and phone workers' ability to offer empathy to clients. It was concluded that discussions of effectiveness should be constrained by a careful consideration of the specific index of efficacy chosen by investigators as well as methodological issues associated with current research in this area. There is reason to believe that the availability of telephone crisis services may be related to reduced suicide rates among young white females. Also, there is a significant need to empirically associate counseling technique and indices of effectiveness with substantive measures of client outcome in future research. Additional topics reviewed include the probable differential effectiveness of lay workers with various presenting problems of clients, and the role that training and maturity seem to play in successful interventions. Guidelines for the use of evaluation techniques which coincide with service goals are also offered. 相似文献
One of the most serious psychosocial problems worldwide is substance abuse because of its repercussions not only on the physical and psychological health of the abuser but also on their relational functioning. Among the well-established therapeutic approaches for the treatment of substance abuse is family therapy, which, in addition to influencing personal variables, promotes changes in family dynamics. The main objective of this study is to review the scientific literature published from 2010 to the present on the efficacy and effectiveness shown by family-based treatment approaches for substance use problems both in adolescent and adult samples. In addition, the effect on secondary variables such as family functioning and behavioral problems is evaluated. The empirical evidence accumulated in the last decade and reviewed in the present study indicates that the incorporation of family members in the treatment of substance abuse produces benefits by diminishing consumption and improving family functioning. Limitations of this study and of the research reviewed are discussed and directions for future research are provided. 相似文献
In this paper, I will explore the role of art-making, the experience of trauma and dissociation, and the process of working with self-states from an analytic and creative frame. Relevant literature on dissociation, trauma, and the use of art will be discussed. A case involving my work with an adolescent girl who had experienced sexual abuse from a family member will be shared, with an emphasis on the meaningful role images played during the therapeutic process. Both Jungian and psychoanalytic models of conceptualizing and working with dissociation are included, following Donald Kalsched’s (2013) recommendation for a “binocular stance” to treatment, including both a focus on the inner, intrapsychic world and the interpersonal, relational realm, and how art images both illuminated and expressed these realms. Within the therapeutic process, art images allowed the therapist a view into the client’s unconscious process, and created a meeting ground for dissociative barriers to be gradually seen, felt and known, by both therapist and client. The experience of dissociation, in images and in session, provided a reference point for myself and my client, Taylor, to develop a shared understanding and a framework for growth. 相似文献
From the perspective of mathematical practice, I examine positions claiming that mathematical objects are introduced by human agents. I consider in particular mathematical fictionalism and a recent position on social ontology formulated by Cole (2013, 2015). These positions are able to solve some of the challenges that non-realist positions face. I argue, however, that mathematical entities have features other than fictional characters and social institutions. I emphasise that the way mathematical objects are introduced is different and point to the multifaceted role that relations and interconnections play in this context. Finally, I argue that mathematical entities can be considered to be pragmatically real.
This research investigates both the downstream effect of perceived brand authenticity on consumers' actual, consequential choice and the important role of inferred brand dedication in the relationship between perceived brand authenticity, anticipated quality, and purchase intentions. We also investigate the interactive effect of two source-related factors—intrinsic motivation and congruity—on consumers' brand authenticity perceptions. We present findings from three studies using different product categories (utilitarian/consumable: hand sanitizer; hedonic/consumable: chocolate; hedonic/non-consumable: sunglasses). Study 1 shows that consumers use information regarding the intrinsic motivation of those behind the brand and congruity between the brand's actions and what it represents to consumers when forming brand authenticity perceptions and that intrinsic motivation and congruity interact to increase authenticity perceptions. We anticipate that consumers' positivity toward brands perceived as authentic will extend to actual choice through anticipated quality. Study 2 demonstrates that consumers choose authentic brands over inauthentic brands above what chance would dictate and anticipated quality can forecast this choice. Next, we extend our collective process knowledge by exploring an underlying reason why consumers anticipate that brands presented through marketing communications as authentic will have higher quality. We suggest that when managers present brands as authentic, consumers infer greater dedication of those behind the brand and inferred dedication influences anticipated product quality. Study 3 provides support and uncovers a serial mediation process, highlighting the importance of inferred dedication. Specifically, perceived brand authenticity increases consumers' brand dedication inferences, which in turn increases anticipated product quality, and ultimately purchase intentions. 相似文献
