无意识元认知调控下的策略转换

通过两位数乘法算式答案判别任务研究无意识元认知调控下策略转换的的认知加工特征。整个算式答案判别任务分为两种策略使用情境：一种为只可以使用尾数策略的任务情境;另一种为既可以使用尾数策略,又可以使用奇偶策略的任务情境。实验结果表明：1）无意识元认知具有高选择性、高效性和高潜力,能在策略使用情境转变之后,快速察觉并选择使用更为简单、高效的奇偶策略;2）尾数策略使用的强大思维定势阻止奇偶策略的意识化,致使绝大多数被试未能发现任务情境的变化而在内隐状态下使用了奇偶策略;3）策略在内隐或外显状态下使用具有同等效力,策略内隐使用具有高效性和高潜力。     

学习困难儿童的元记忆监测与控制特点

以有无意义联系的两种中文词对为材料,采用2×3×2混合实验设计,对小学三到五年级学习困难儿童的元记忆监测、控制水平与学优儿童之间的差异及其发展特点进行研究。结果表明：1．学习困难儿童在三种元记忆监测判断等级上均显著低于学优儿童。2．学习困难儿童具有元记忆控制能力,但其控制水平相对低于学优儿童。3．学习困难儿童的元记忆监测判断和学习时间分配之间存在交互影响。4．学习困难儿童的元记忆监测和控制水平存在较为复杂的发展特点。据此得出结论认为,学习困难儿童的元记忆监测与控制能力都比学优儿童差,同时也表现出一定的发展趋势。     

An inexpensive 1-millisecond experiment control interface for IBM PCs and its user-friendly control language

An inexpensive, professionally manufactured, digital I/O experiment control interface for any PC-compatible computer is described. It plugs into a standard printer port and provides 1-msec accuracy for up to 4 inputs and 22 outputs. It also allows experiment control procedures to be written in an easy-to-learn, easy-to-use Experiment Control language (ECBASIC). In addition to many instructions specifically designed to simplify behavioral research, ECBASIC provides for transparent collection and storage of event logs.     

Creating a hypertext markup language document for an information server

This paper briefly overviews the World-Wide Web. It then provides a short tutorial on the use of the hypertext markup language to publish information on the web. Hypertext markup language is a special page-layout language that was developed to help make creating and retrieving information on the web consistent and efficient. Hyperlinks within hypertext markup language make the language especially powerful because they enable the browser to transparently retrieve images, movies, or audio files from virtually any computer on earth simply by clicking on an item displayed on the monitor.     

Vaginal scent marking: effects on ultrasonic calling and attraction of male golden hamsters

Male hamsters were tested for their responses to areas that had been scent marked by intact or vaginectomized females to determine the effects of naturally deposited vaginal secretions on male behavior. In the first experiment males produced more ultrasonic courtship calls when investigating areas marked by intact females than areas scented by vaginectomized females, demonstrating that vaginal marks facilitate such calling. In a wind-tunnel preference test situation in which scent-marked alleys and clean alleys served as sources of odor, males approached the scented alley first if it had been freshly marked by intact females but not if it had been scented by vaginectomized females or other males. Thus, the odors of vaginal marks are sufficient to attract males over short distances. After males entered these alleys they showed a preference for odors of both intact and vaginectomized females over no odors, but still spent significantly more time investigating the odors of intact females than those of vaginectomized females. These experiments indicate that vaginal secretions are one of the primary cues that elicit male courtship calling, and the small quantities of vaginal secretions deposited by females in vaginal marks are sufficient to elicit ultrasonic calling and attract males over short distances. Thus it is likely that vaginal scent marking and ultrasonic calling by females interact to facilitate attraction and location of mates during courtship.     

Minority Influence, Divergent Thinking and Detection of Correct Solutions

In many applied settings involving influence processes in small groups, the interest is in how such processes aid or hinder effective decision making and problem solving. In a recent formulation, Nemeth (1986) argued that exposure to opposing views emanating from a minority leads to divergent thinking, a process that involves a consideration of the problem from varying viewpoints. On balance, such influence would aid performance. Exposure to opposing majority viewpoints leads to convergent thought where S s presumably concentrate on the proposed viewpoint to the exclusion of other considerations. On balance, this form of influence tends not to aid performance and may prove to be an impediment. In the present study, these hypotheses were tested in the context of anagram solutions. Results showed that subjects exposed to the minority viewpoint found more correct words and they achieved this superior performance by a usage of all possible strategies. Subjects exposed to the majority viewpoint initially used the strategy suggested by the majority to the detriment of other strategies and, in general, performed at the level of control subjects. These results are discussed in terms of potential contributions made by exposure to dissenting minority viewpoints in small group decision-making settings such as trial by jury and in society at large.     

Examining the initial usability,acceptability and feasibility of a digital mental health intervention for college students in India

Generalised anxiety disorder (GAD) is prevalent among college students in India; however, barriers like stigma, treatment accessibility and cost prevent engagement in treatment. Web- and mobile-based, or digital, mental health interventions have been proposed as a potential solution to increasing treatment access. With the ultimate goal of developing an engaging digital mental health intervention for university students in India, the current study sought to understand students' reactions to a culturally and digitally adapted evidence-based cognitive behavioural therapy (CBT) for GAD intervention. Specifically, through theatre testing and focus groups with a non-clinical sample of 15 college students in India, the present study examined initial usability, acceptability and feasibility of the “Mana Maali Digital Anxiety Program.” Secondary objectives comprised identifying students' perceived barriers to using the program and eliciting recommendations. Results indicated high usability, with the average usability rating ranking in the top 10% of general usability scores. Participants offered actionable changes to improve usability and perceived acceptability among peers struggling with mental health issues. Findings highlight the benefits of offering digital resources that circumvent barriers associated with accessing traditional services. Results build on existing evidence that digital interventions can be a viable means of delivering mental healthcare to large, defined populations.     

An Examination of the Connections Between Eating Disorder Symptoms,Perceived Burdensomeness,Thwarted Belongingness,and Suicide Risk Among Undergraduate Students

Suicide attempts and premature mortality due to suicide are elevated in people with eating disorders. Informed by the interpersonal theory of suicide, two studies examined the role of perceived burdensomeness and thwarted belongingness in explaining the association between eating disorder symptoms and suicide risk. Results indicated that various eating disorder symptoms had an indirect effect on suicide risk through perceived burdensomeness and thwarted belongingness. Targeting perceived burdensomeness and thwarted belongingness may be useful for decreasing suicide risk among undergraduates with eating disorder symptoms.
