Concept learning by pigeons: Matching-to-sample with trial-unique video picture stimuli

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.     

Fire play: ICCARUS—Intelligent command and control,acquisition and review using simulation*

Is it possible to educate a fire officer to deal intelligently with the command and control of a major fire event he will never have experienced? The authors of this paper believe there is, and present here just one solution to this training challenge. It involves the development of an intelligent simulation based upon computer managed interactive media. The expertise and content underpinning this educational development was provided by the West Midlands Fire Service. Their brief for this training programme was unambiguous and to the point:

• 1 Do not present the trainee with a model answer, because there are no generic fires. Each incident is novel, complex, and often ‘wicked’ in that it changes obstructively as it progresses. Thus firefighting demands that Commanders impose their individual intelligence on each problem to solve it.
• 2 A suitable Educational Simulator should stand alone; operate in real time; emulate as nearly as possible the ‘feel’ of the fireground; present realistic fire progress; incorporate the vast majority of those resources normally present at a real incident; bombard the trainee with information from those sources; provide as few system‐prompts as possible.
• 3 There should also be an interrogable visual debrief which can be used after the exercise to give the trainees a firm understanding of the effects of their actions. This allows them to draw their own conclusions of their command effectiveness. Additionally, such a record of command and control will be an ideal initiator of tutorial discussion.
• 4 The simulation should be realisable on a hardware/software platform of £10 000.
• 5 The overriding importance is that the simulation should ‘emulate as nearly as possible the feelings and stresses of the command role’.

     

Auditorysame/different concept learning by monkeys

Two rhesus monkeys learned the auditory abstract concept ofsame/different. They were trained with 38 different environmental and natural sounds, which were arranged in different combinations as training progressed. Upon transfer to 138 different novel stimuli, they performed as well (78.8% correct) on the first exposure to the novel stimuli as they did (77.3%) with their training stimuli. The comparatively large set of training sounds, contact with the sound source, and a special fading procedure are thought to have contributed to the monkeys’ being able to learn this concept. Implications for species’ similarities/differences in cognitive processing are discussed.     

An approach to psychosexual counselling

Summary In considering in this paper the origins, development and need for psychosexual counselling to be an integral part of the provision of a counselling service, one must not lose sight of the fact that some higher educational institutions still have no general counselling provision.It is interesting to note that in the UK at a time when the age of consent and voting age were lowered to eighteen years (Family Law Reform Act, 1969, operational 1970 and Representation of the People Act, 1969), and students were rejecting the idea of wardens and academic tutors acting in loco parentis, the National Union of Students (at their annual conference in 1969) passed a resolution pressing for Counselling Services to be established in each higher educational institution-staffed by fully trained personnel, Milner (1974). Nine years later this resolution has not yet been fully implemented.The university community represents a cross-section of the population, any of whom may have a psychosexual problem and seek help from the counselling service. Counsellors must be trained to treat psychosexual problems as part of their normal range of activities.Storr (1960) points out that it is The individual as well as the disease that needs treatment. This applies in counselling as it does in medicine, so that the counsellor should be able to treat the individual as a whole, and at the same time treat his psychosexual problem.University of Reading     

A meta-analytic investigation of therapy modality outcomes for sexually abused children and adolescents: an exploratory study

OBJECTIVE: The purpose of the current study was to investigate the independent effects of different treatment elements on a number of secondary problems related to childhood and adolescent sexual abuse, as well as investigate a number of different moderators of treatment effectiveness. METHOD: Twenty-eight studies that provided treatment outcome results for children and adolescents who had been sexually abused were included in the meta-analysis. Different aspects of psychological treatment, such as specific treatment modalities (individual, cognitive-behavioral, etc.) or secondary problems (behavior problems, psychological distress, etc.) were investigated. RESULTS: The overall mean weighted effect size for the meta-analysis was d=.72 (SE=.02). The results indicate that psychological treatment after childhood or adolescent sexual abuse tended to result in better outcomes than no treatment. There was significant heterogeneity in the effectiveness of the various psychological treatment elements. Play therapy seemed to be the most effective treatment for social functioning, whereas cognitive-behavioral, abuse-specific, and supportive therapy in either group or individual formats was most effective for behavior problems. Cognitive-behavioral, family, and individual therapy seemed to be the most effective for psychological distress, and abuse-specific, cognitive-behavioral, and group therapy appeared to be the most effective for low self-concept. CONCLUSIONS: The choice of therapy modality should depend on the child's main presenting secondary problem. Further research should be conducted investigating other possible moderators and secondary problem outcomes.     

Bilingual Mathematics

在加拿大。有人讲英语,有人讲法语,于是加拿大就将英语和法语都定为自己的官方语言。其实,加拿大不仅仅在官方语言上实施“一国两制”,在度量单位上也是公制和英制交替使用。这给加拿大人生活带来了些许不便。Brad也常为之头疼。
