中学生知识获得过程是从情景记忆向语义记忆转化的过程

本研究探讨中学生的知识掌握过程。针对2001—2002年度上学期教学内容,对初中二年级学生的四门课程分别进行两次测验。对于每道选择题,学生首先选择正确答案,然后指出记忆的意识状态：记住的、知道的、猜测的。结果发现,学生记忆意识类型的转变(由记住向知道)取决于课程类型、保持时间和学生等级。对于不同课程,学生占优势的意识类型不同,自然学科知道的反应占优势,社会学科记住的反应占优势;优等生知道的反应多于其他学生;随着学习时间的延长,中学生的意识类型发生了由记住向知道的转变,这表明知识掌握过程中,中学生的知识表征发生了由情景记忆向语义记忆的转变。     

Following slower drivers: Lead driver status moderates driver’s anger and behavioural responses and exonerates culpability

Two experiments investigated the effects of lead-driver status on the anger-experienced and aggression-expressed in traffic scenarios in which the lead drivers’ actions were determined by an event obviously beyond, or within, their control. Experiment I contrasted reactions to lead-cars bearing Learner driver markings (Low Status) or similar unmarked cars (Control), while Experiment II contrasted reactions to Ambulances (High Status) or otherwise identical generic work vans (Control). Reported anger, heart-rate and behaviour were measured while drivers drove. When the lead vehicle slowed or changed course because of the actions of another road user, drivers were reliably more angered when slowed by a learner driver than an unmarked sedan. Drivers reported less anger when slowed by an Ambulance, than by a work van, when there was no apparent cause for the lead-vehicle slowing. Driver behaviour also differed according to lead-vehicle status. Drivers allowed greater headway between themselves and a slower ambulance, but drove closer to the work-van, and followed Learner drivers at a dangerously close distance, leaving greater headway behind a similar, unmarked car. Reliable differences in subjective anger ratings and behaviour suggest that anger experienced and expressed depends not just on the actions of the perpetrator but on the perceived status of that perpetrator. Higher status vehicles appear to be forgiven their indiscretions more readily even when there are no extenuating circumstances, whilst lower status drivers are likely to be blamed more readily for circumstances beyond their control.     

Survival from the Brain's Perspective

The concern about man's harmful impact on the environment focuses attention on the external environment, i.e., the real world out there, which may not survive in a form to support life. But supporting life of an individual is in the hands of that individual's brain, which is primarily concerned with various needs of the internal environment, also referred to as the self. Confronted with diverse and often competing needs, the brain has evolved a complexity in man, which makes it doubtful that any one collective strategy may be effective in preserving the external environment.

Enrichment and Stress in Families Caring for a Child with a Serious Emotional Disorder

We examined enrichment and stress in 214 families who had children with severe emotional disorders. Caregivers' ratings of enrichment and stress were obtained through a newly developed instrument, the Effects of the Situation Questionnaire, which used parallel items covering 17 life areas. While ratings of stress were generally higher than enrichment, caregivers reported some enrichment in areas encompassing self concept and family relationships, Bivariate and multivariate analyses using various child, family, and service-system variables revealed that stress was notably associated with severity of the child's disorder, low empowerment, and a lack of coordination among service providers. Enrichment was unrelated to severity but associated with high empowerment and spiritual support. Our findings suggest that families' experiences of caregiving can have both positive and negative aspects and that a comprehensive approach to serving and studying families should take both into account.     

MODIFICATION OF HUMAN GASTRIC ACID SECRETION WITH OPERANT-CONDITIONING PROCEDURES1

In an attempt to control gastric acid secretion with operant-conditioning techniques, four normal women were given visual feedback on gastric pH plus money reinforcers. When money was made dependent on increased secretion in a differential-reinforcement-of-high-rates schedule, the rate of secretion of three of the four subjects increased to three times baseline. When money was then made dependent on decreased secretion in a differential-reinforcement-of-other-behaviors schedule, the rate of secretion of these three subjects returned to baseline levels. Heart rate, respiratory frequency, abdominal electromyographic activity, and stomach motility (measured by the electrogastrogram method) were not consistently correlated with acid secretion across subjects, although individual subjects showed substantial correlations between acid secretion and one or more other physiological response.     

Help Wanted: People With Disabilities and Recruitment Advertising

People with disabilities rely heavily on specialist agencies to find suitable employment. This research examines how agency consultants use recruitment ads in their work with clients. The authors analyzed the ads collected by consultants and learned that the ads were dominated by organization and job attributes. The ads contained less information about preferred applicant characteristics and selection procedures. Consultants used the ads to facilitate immediate matches between clients and employers, but they also used the ads to nudge clients in new career directions. The results reflect challenges consultants experience in balancing the long‐term needs of clients against the short‐term demands of employers.     

The effect of geographic indication in advertising background pictures on product evaluation: The moderating role of familiarity

This study investigates whether geographic indications in the backgrounds of advertising pictures might affect the viewer's evaluation of a product. The findings reveal that participants in the proximal geographic indication evaluated the product more favourably than those in the distal geographic indication when they were exposed to feasibility‐related information. By contrast, participants in the distal geographic indication evaluated the product more favourably than those in the proximal geographic indication when they were exposed to desirability‐related information. However, familiarity with geographic indications eliminated this effect.     

‘It’s silly these doors don’t open’: a six-year-old girl emerges from a chronic state of emotional withdrawal

This clinical paper explores the way in which the first two years of a long-term psychotherapy helped six-year-old Anna to lessen her retreat into a chronic withdrawn emotional state. Over the course of the first year she would occasionally pick up the fridge from the doll’s house and try to open the doors, but because the fridge was actually a block of wood the doors could not open. In treatment, this inquiry came to represent the difficulties of engaging and making contact with a baby who found it very hard to feed. The author describes how, as Anna entered into a therapeutic relationship, it slowly became clear that there was an inner world jam-packed with persecutory anxieties and a family history of unmourned loss and trauma. Through fear Anna slammed the doors to her mind – to knowing herself – and by not feeding, Anna starved herself of opportunities for mental growth. It took some time for her to state, “it’s silly these doors don’t open, they should”. In the discussion of this clinical material the author draws on the work of Francis Tustin, Alessandra Piontelli and Marguerite Reid to consider the link between intergenerational and prenatal trauma and subsequent emotional disturbance in the child.
