The maintenance of cooperative and helping behaviours in cooperative groups.

BACKGROUND: This study was a full-year investigation of whether children, who had previously been trained to cooperate and help each other, were able to use these behaviours in reconstituted groups without additional training one year later. AIMS: (i) To examine whether children who have previously been trained to cooperate demonstrate more cooperative and helping behaviours in their groups than children who had no been trained and (ii) to determine the effect of prior training on children's learning. SAMPLE: The study involved 144 Grade 2 children (mean age = 94.5 months; third year of schooling), from nine schools in a similar socio-demographic area of Brisbane, Australia. Sixty-four children, who had been trained in cooperative group behaviours in the previous year, were assigned to the Trained groups and 80 children, who had not received any training, were assigned to the Untrained groups. METHOD: The children worked in four-person, mixed-ability (high-, medium-, and low-ability), gender-balanced groups (2 males, 2 females) for one six-week social studies unit of work each term for three school terms. Videotaping occurred in the 5-6 week of each work unit. Videotapes were coded for behaviour and verbal interactions. Learning outcomes data were also collected. RESULTS: The children in the trained groups exhibited more cooperative behaviour and they provided more explanations, both in response to explicit and implicit requests for help across the three periods of time. The children in the trained groups used higher level cognitive strategies such as providing specific concrete facts and reasons in their interactions and they also obtained higher scores on the learning outcomes questionnaire than their untrained peers. CONCLUSION: Young children who have been trained to cooperate and help each other are able to demonstrate these behaviours in reconstituted groups without additional training a year later.

The Montreal Type A Intervention Project: major findings.

This article reports a comparison of three short-term treatments (aerobic exercise, cognitive-behavioral stress management, and weight training) in modifying behavioral and cardiovascular reactivity to laboratory psychosocial stressors in healthy Type A men. One hundred seven men completed the treatments and evaluations, 33 in the aerobic exercise group, and 37 each in the cognitive-behavioral stress management and weight-training groups. The stress management group showed significantly greater changes in behavioral reactivity (reductions of 13% to 23% below initial values) than the two physical exercise groups, which did not differ significantly from each other. For physiological reactivity, changes attributable to intervention were trivial for all three treatment groups. The positive finding of reduced behavioral reactivity as a result of the stress management intervention is of potential clinical significance and warrants further exploration. The lack of meaningful reductions in physiological reactivity also requires further exploration in that it raises questions concerning the ability of behavioral treatments in general to modify physiological reactivity, the ability of existing measures to assess accurately changes that are produced and, most fundamental of all, the relevance of physiological reactivity as an outcome measure for treatment efforts with Type As.

Virtual reality and cognitive assessment and rehabilitation: the state of the art.

VR offers the potential to develop human testing and training environments that allow for the precise control of complex stimulus presentations in which human cognitive and functional performance can be accurately assessed and rehabilitated. However, basic feasibility issues need to be addressed in order for this technology to be reasonably and efficiently applied to the neuropsychological assessment (NA) and cognitive rehabilitation (CR) of persons with acquired brain injury and neurological disorders. This chapter will provide an introduction to the basic concepts of neuropsychological assessment and cognitive rehabilitation along with rationales for virtual reality's applicability in these complimentary fields. We review the relevant literature regarding theoretical and pragmatic issues for these applications, and provide a description of our ongoing work developing a mental rotation/spatial skills cognitive assessment and training system. References are provided in each section for further reading in each area reviewed.

Improving spatial functioning in children with cerebral palsy using computerized and traditional game tasks.

PURPOSE: To examine the effectiveness of combining virtual environment (VE) instruction with additional desk-top tasks, based on the Luria-Vygotsky methodology, for spatial remediation in children having complex motor disabilities restricting movement. METHODS: In Experiment 1, from among children attending for residential rehabilitation, an experimental subgroup had additional spatial training using a VE and corresponding desk-top models. All children were tested at the start and end of training, using four spatial tests. In Experiment 2, larger groups of children (pair-matched for initial performance) were given the same training as in Experiment 1, but experimentals received both VE-based training and supporting tasks designed to improve executive functions and verbal regulation of spatial functioning. Assessment involved a wider range of tests than in Experiment 1. RESULTS: In Experiment 1, both groups showed improvement at retest, but experimentals showed greater improvement. Children beginning with the lowest level of cognitive performance failed to benefit from the additional training. In Experiment 2 the experimental group made significantly greater improvement than controls, irrespective of initial performance level. CONCLUSIONS: VE-based spatial training is effective for children with complex disabilities, particularly when combined with training that remediates cognitive weaknesses.

Long-term durability and transfer of enhanced conceptual performance in the elderly.

To evaluate the durability and transfer of enhanced cognitive functioning in the elderly, subjects (ages 64 to 84) who had previously participated in a unidimensional concept identification study were tested on a bidimensional conjunctive concept identification problem. The conjunctive problem was administered approximately 12 mo after completion of the unidimensional study. In the earlier unidimensional study, substantial and equivalent improvement had been found with both a training group and a reinforced training group. In this study, efficient conjunctive problem solving was found with the (unidimensional) training group, showing that enhanced cognitive performance can be durable and transfer to a similar task. Durability and trasnfer were not observed with the (unidimensional) reinforced training group, however, a finding that appears to have resulted from the extrinsic reinforcement token system employed in the unidimensional training with that group.

Psychotherapy in the overall management strategy for social anxiety disorder.

Cognitive-behavioral therapies (CBTs) are effective treatments for social anxiety disorder/social phobia. Although a variety of procedures are included under the term cognitive-behavioral treatment, it is, however, clear that the key factor influencing treatment outcome for social anxiety disorder is exposure to feared situations. Two formalized CBT programs are cognitive-behavioral group therapy (CBGT) and social effectiveness training (SET). They both involve exposure, but differ in that CBGT focuses on correction of cognitive errors, whereas SET uses social skills training in addition to exposure to feared social situations. CBGT is more efficacious than a psychological placebo and has shown efficacy comparable to that of phenelzine in a double-blind, placebo-controlled study. The onset of effect of phenelzine was more rapid, whereas the effect of CBGT was more sustained. The major component of SET, imaginal and/or in vivo exposure, has been demonstrated to be more effective than pill placebo or the beta-blocker atenolol. Many questions remain regarding CBT strategies and their place in the overall management of patients with social anxiety disorder. Depending upon the particular patient profile, various combinations of drug and/or CBT may prove to be the optimal treatment strategy.

Reality orientation and dementia: a controlled trial of two approaches.

Classroom Reality Orientation was investigated with a sample of dements drawn from a psychogeriatric hospital and an old people's home. Treatment effects were examined on a range of cognitive and behavioural measures, and compared with the effects of a specific behaviourally directed orientation training in the ward. Class RO improved cognitive functioning but not behaviour, irrespective of degree of dementia. Highly significant behavioural change was demonstrated for ward behaviour orientation training and this technique is not only cheaper but has potential in managing dements.

DNA methylation age deviation and cognitive status among older adults in the US, NHANES 1999-2002.

Biological aging, measured using DNA methylation, is a potential biomarker for cognitive health outcomes. We evaluated associations between DNA methylation measures of aging and cognition in a nationally representative sample of adults aged 60+ in the National Health and Nutrition Examination Survey (NHANES), 1999-2002. Genome-wide DNA methylation data were used to create 13 measures of biological aging trained on different aging phenotypes. Cognition was assessed with the Digit Symbol Substitution Test (DSST). To evaluate associations between each DNA methylation measure and DSST score, survey-weighted linear regression models adjusted for age, sex, race/ethnicity, education, smoking, serum cotinine, and BMI were run. We assessed effect modification by sex, education, and race and ethnicity. Included participants (N=1,463) were an average of 70.5 years old and 82.7% non-Hispanic White. The average DSST score was 46.9 (SD 17.6). Ten of 13 DNA methylation measures were associated with DSST (adjusted p<0.05). One year of GrimAge2 accelerated aging was associated with -0.41 points lower DSST score (95% CI: -0.61, -0.21; adjusted p=5&#xd7;10-4). In stratified analyses, higher magnitudes of association were observed among male and non-Hispanic White participants across multiple aging measures. DNA methylation may be a useful biomarker of cognitive status among older adults.

Getting ready for reading: a follow-up study of inner city second language learners at the end of Key Stage 1.

BACKGROUND: A previous study (Stuart, 1999) showed that early phoneme awareness and phonics teaching improved reading and spelling ability in inner-city schoolchildren in Key Stage 1, most of whom were learning English as a second language. AIMS: The present study, a follow-up of these children at the end of Key Stage 1, addresses four main questions: (1) Are these improvements maintained to the end of Key Stage 1? (2) Are different patterns of cognitive process evident in the word recognition skills of phonics trained versus untrained children? (3) Do the phonics trained children now also show a significant advantage in reading comprehension? (4) Are there differences in amount of reading, in self-concept as readers and in oral vocabulary development between phonics trained and untrained children? Relationships between reading and spelling ages and Key Stage 1 SATs levels are also explored. SAMPLE: Data are reported from 101 seven-year-olds (85 of whom were second language learners) remaining from the original 112 children reported on previously. METHOD: Children were tested on four standardized tests of reading, spelling and vocabulary, and on a further six experimental tests of phoneme segmentation, grapheme-phoneme correspondence knowledge, regular, exception and nonword reading, author recognition and reading self-concept. RESULTS: Lasting influences of early phoneme awareness and phonics teaching on phoneme awareness, grapheme-phoneme correspondence knowledge, word reading and spelling were found. Part of the previously untrained group had now received structured phonics teaching, and were therefore treated as a third (late trained) group. Early and late-trained groups showed similar levels of attainment and similar cognitive processing patterns, which were different from the untrained group. However, there were no influences of training on reading comprehension, self-concept or oral vocabulary. CONCLUSIONS: Early phoneme awareness and phonics training efficiently accelerates the word recognition and spelling skills of first and second language learners alike. However, this is not sufficient to bootstrap the development of language comprehension in the second language learners. Further research is needed into the kinds of language teaching that will best develop their oral and written language comprehension.

Musician children detect pitch violations in both music and language better than nonmusician children: behavioral and electrophysiological approaches.

The idea that extensive musical training can influence processing in cognitive domains other than music has received considerable attention from the educational system and the media. Here we analyzed behavioral data and recorded event-related brain potentials (ERPs) from 8-year-old children to test the hypothesis that musical training facilitates pitch processing not only in music but also in language. We used a parametric manipulation of pitch so that the final notes or words of musical phrases or sentences were congruous, weakly incongruous, or strongly incongruous. Musician children outperformed nonmusician children in the detection of the weak incongruity in both music and language. Moreover, the greatest differences in the ERPs of musician and nonmusician children were also found for the weak incongruity: whereas for musician children, early negative components developed in music and late positive components in language, no such components were found for nonmusician children. Finally, comparison of these results with previous ones from adults suggests that some aspects of pitch processing are in effect earlier in music than in language. Thus, the present results reveal positive transfer effects between cognitive domains and shed light on the time course and neural basis of the development of prosodic and melodic processing.

Implementing integrated treatment for co-existing substance use and severe mental health problems in assertive outreach teams: training issues.

This study sought to evaluate systematically training and implementation of a specific integrated treatment approach for co-occurring problem substance use and mental health within existing assertive outreach (AO) teams. The AO team was treated as a whole unit rather than as individual clinicians. They were provided with training and supervision to deliver a cognitive--behavioural integrated treatment approach. In a quasi-experimental time-lag design three teams were trained immediately and two others after an 18-month delay. There was evidence that teams acquired confidence and skills relevant to working with combined problems and that these gains were maintained over time. These results were replicated in the two teams trained after the delay. This study suggests that training mental health staff to use an integrated treatment approach is well received and produces lasting changes in confidence and skills. However, there are a number of issues related to staff training, shifting attitudes and implementation of integrated approaches into routine mental health practice. These issues are considered and suggestions made for staff training.

Prevalence and symptoms of delirium superimposed on dementia.

Delirium is a frequent syndrome among patients who are elderly. People who are older with cognitive impairment who are institutionalized are at increased risk of developing delirium when hospitalized. In addition, their prior cognitive impairment makes detecting their delirium a challenge. This study goal was to describe the effect of severity of prior cognitive impairment on delirium prevalence and symptom presentation among patients who were older and were newly admitted to an acute care hospital. A total of 104 were included in this descriptive study and screened for delirium. The results showed that the prevalence of delirium increased according to the severity of the patients' prior cognitive impairment. Except for disorganized thinking, all symptoms of delirium were similar among patients with mild, moderate, and severe prior cognitive impairment. The study concluded that training nurses to recognize subtle changes in mental status among those patients who were older with prior cognitive impairment may prevent the underdetection of delirium.

[Cognitive therapy].

This paper offers an introduction to cognitive therapy which gives special importance to schemas of thinking in the expression of affect and behavior. Depression is a disease in which distorted and idiosyncratic patterns of thinking are activated; these are the major target of cognitive therapy. This therapy obeys specific laws and techniques based on scientific data and thus requires special training. The improvement of depression through cognitive therapy leads to the disappearance of depressive symptoms and the birth of adequate patterns for the management of psychic equilibrium. A plethora of publications emphasize the efficacy of cognitive therapy in the treatment of depression. This technique is in use, in Lebanon, in the Clinical and Research Service of Psychiatry and Psychology at St. Georges Hospital, Beirut.

Effects of functional training of dysphagia to prevent pneumonia for patients on tube feeding.

OBJECTIVE: The purpose of this study was to evaluate the effects of functional training on outbreak frequency of pneumonia for the elderly dysphagia patients who were being tube fed. METHODS: Subjects were divided into two groups; one group (n = 10) received oral care (i.e. non-training group) and the other group (n = 11) received functional training of dysphagia in addition to oral care (i.e. training group). The dental health team treated subjects once a week for 3 years (1999-2001). The frequency of pneumonia outbreaks and changes in activities of daily living scale (ADL) were evaluated for each year. RESULT: It was recognised that the frequency of pneumonia in the training group decreased year by year (p < 0.05). Cognitive items in ADL improved in two subjects of the training group. No statistical differences were recognised in the non-training group. CONCLUSION: It was suggested that once-a-week functional training of dysphagia with professional oral care might be effective in preventing pneumonia for elderly people who were being tube fed.

Training to estimate blood glucose and to form associations with initial hunger.

BACKGROUND: The will to eat is a decision associated with conditioned responses and with unconditioned body sensations that reflect changes in metabolic biomarkers. Here, we investigate whether this decision can be delayed until blood glucose is allowed to fall to low levels, when presumably feeding behavior is mostly unconditioned. Following such an eating pattern might avoid some of the metabolic risk factors that are associated with high glycemia. RESULTS: In this 7-week study, patients were trained to estimate their blood glucose at meal times by associating feelings of hunger with glycemic levels determined by standard blood glucose monitors and to eat only when glycemia was < 85 mg/dL. At the end of the 7-week training period, estimated and measured glycemic values were found to be linearly correlated in the trained group (r = 0.82; p = 0.0001) but not in the control (untrained) group (r = 0.10; p = 0.40). Fewer subjects in the trained group were hungry than those in the control group (p = 0.001). The 18 hungry subjects of the trained group had significantly lower glucose levels (80.1 +/- 6.3 mg/dL) than the 42 hungry control subjects (89.2 +/- 10.2 mg/dL; p = 0.01). Moreover, the trained hungry subjects estimated their glycemia (78.1 +/- 6.7 mg/dL; estimation error: 3.2 +/- 2.4% of the measured glycemia) more accurately than the control hungry subjects (75.9 +/- 9.8 mg/dL; estimation error: 16.7 +/- 11.0%; p = 0.0001). Also the estimation error of the entire trained group (4.7 +/- 3.6%) was significantly lower than that of the control group (17.1 +/- 11.5%; p = 0.0001). A value of glycemia at initial feelings of hunger was provisionally identified as 87 mg/dL. Below this level, estimation showed lower error in both trained (p = 0.04) and control subjects (p = 0.001). CONCLUSION: Subjects could be trained to accurately estimate their blood glucose and to recognize their sensations of initial hunger at low glucose concentrations. These results suggest that it is possible to make a behavioral distinction between unconditioned and conditioned hunger, and to achieve a cognitive will to eat by training.
