Acquired procedural dyscalculia associated to a left parietal lesion in a child.

We report the case of an 11-year-old boy who developed an anarithmetia in association with a left temporo-parietal tumor. His oral and written language were normal as well as his ability to judge magnitudes, process numbers, read operation signs and retrieve number facts. He had a specific difficulty in performing the procedures of subtraction, especially when it involved borrowing. These skills had been mastered before the present illness. This case shows that the components of calculation can be dissociated by brain lesions sustained during childhood, while arithmetic abilities are being acquired, thus reinforcing findings from developmental dyscalculias, that suggest a modular organisation of those skills during development.     

Long-term retention of a motor skill: Implicit sequence knowledge is not retained after a one-year delay

Experimental work shows that some motor skills are retained well over a long delay and others are not. It is possible that motor tasks that are primarily implicit are retained over long intervals, whereas those with an explicit component are subject to more rapid forgetting. To test whether implicit motor skills are retained, 24 (experienced) participants were retested after a one-year delay for their retention of an implicit motor sequence. They had been trained on the sequence in a button-pushing task. Although the experienced participants responded faster than they had a year earlier, they showed no retention of the sequence compared to 24 participants who had received no training a year earlier, and no savings in relearning the sequence. The overall speed effect may indicate that the amount of training is crucial to the degree of retention of a skill. The results indicate that it is not the case that implicit motor skills are well retained whereas those with an explicit component are not.     

Effects of communication skills on stress responses while speaking Japanese and English

The present study was conducted to examine the effects of communication skills on stress responses, such as physiological (blink and heart rate), emotional (state of anxiety and mood), and behavioral responses (smiling and expressing an opinion) in stressful communication situations, specifically answering questions and giving a speech in Japanese and English. Participants were 32 students (16 men and 16 women; Mage = 19.5 yr., SD = 1.3) attending a Japanese university. A high communication skills group was selected from the upper tertile scores of the Social Skills Inventory, and a low communication skills group was selected from the lower tertile scores. Analysis indicated that individuals who had high communication skills performed without heart-rate increase and with more positive attitude during stressful communication tasks. Individuals who had low communication skills displayed higher anxiety prior to the experiment than those who had high communication skills.     

Family Etiology and Remission in a Case of Psychogenic Fugue

A psychogenic fugue lasting six days occurred in a 15-year-old girl living with her mother, sister, and stepfather. The fugue was of the most complete type — the patient assumed a new identity; spoke a foreign language she had studied in school; “regressed” to an earlier period in history; radically altered her dress and grooming; and showed skills, interests, and personality features she had not shown before. Although accounts of fugues are rare and often sketchy, the present case is unique in the amount of detail that was available. The argument between situational and psychodynamic interpretations of fugue is reviewed briefly, and a family systems interpretation of the present case is offered.     

A Dialectical Behavior Therapy Skills Group Case Study on Mothers With Severe Emotion Dysregulation

Parenting is an emotionally demanding endeavor, which can be particularly challenging for parents who struggle with psychopathology and lack the regulation skills to manage their own emotional lability. Although dialectical behavior therapy (DBT) is an effective treatment that directly targets emotion dysregulation, little is known about whether DBT might also improve parenting behaviors. A DBT skills group was employed to examine whether DBT skills are utilized by mothers in their parenting and whether skill use improves parenting. Four mothers with severe emotion dysregulation who met diagnostic criteria for at least one Axis I disorder were part of a case study, in which they completed a DBT skills group for mothers, and two of the mothers participated in an in-depth exit interview regarding their use of DBT skills in their parenting. The mothers reported substantial changes in their parenting during the exit interview and modest improvements were found for parenting in pre- to posttreatment parenting assessments. This paper describes the various parenting contexts in which DBT skills were used and discusses maternal emotion regulation as a potential pathway from DBT skills to improved parenting.     

Event-related brain potentials elicited by rhyming and non-rhyming pictures differentiate subgroups of reading disabled adolescents

Event-related brain potentials were recorded while disabled adolescent subjects read and judged whether two sequentially presented pictures had names that rhymed. Subjects with relatively good phonetic skills displayed an N400 priming effect, i.e., a significant reduction in the amplitude of the negative peak, occurring approximately 400 msec post-stimulus, for pictures with names that rhymed with preceding pictures as compared with pictures that had names that did not rhyme with the prime. No such effect was evident for subjects with relatively poor phonetic skills. This lack of an N400 priming effect provides evidence for a reduction in neural capacity and/or activation during phonological processing in the subjects with poor phonological skills. Demonstrating the N400 priming effect to be stronger in one group of reading disabled subjects, compared to another, supports the position that specific subtypes of reading disability exist. In addition to the stronger N400 priming effect, the phonetically stronger group also exhibited an enhanced negativity, from 700 to 1,000 msec after target stimulus onset, compared to phonetically inferior subjects. This finding replicates earlier work and possibly reflects a higher level of confidence in the group with better phonetic skills.     

Using behavioral skills training with preservice teachers in the university classroom

Preservice and novice teachers often identify behavior management as an area of weakness that they attribute to a lack of sufficient instruction during their teacher preparation. Behavioral skills training (BST) is an evidence‐based teaching methodology based on the principles of applied behavior analysis used to teach new skills. This study investigated the use of BST in the university setting to teach undergraduate preservice teachers enrolled in a field‐based special education course to implement a token economy during small group instruction with children. A single‐case research design was used to assess the effectiveness of using BST by evaluating accuracy of implementation before and after BST. Results showed BST was an effective teaching procedure and social validity measures collected from the preservice teachers indicated BST was acceptable to all participants. Limitations and needs for future research are discussed.     

A Case Study Exploring the Influence of a Gardening Therapy Group on Well-Being

In a climate of improving health-care quality and understanding, this study explored how participation in a gardening group, facilitated through a mental health service in Ireland, influenced well-being. A case study used semi-structured interviews and participant observation to explore explicit and tacit aspects of group participation. Thematic analysis clarified that gardening group participation had a positive influence on well-being for all gardeners and group facilitators. This was through promoting coping, facilitating change, and developing skills. The setting, site ethos and tasks were important in assisting people to make lifestyle changes and to develop skills in order to experience well-being.     

Why do the effects of delaying reinforcement in animals and delaying feedback in humans differ? A working-memory analysis

Animal research has shown that reinforcement is substantially less effective when it is delayed, but in studies of human motor learning delays in providing feedback typically have much less effect. One possible explanation is that in human research participants know the response to be learned and can thus focus on it during the delay; that is not the case in experiments on animals. We tested this hypothesis using a task in which participants had minimal information on what movement was correct and found that, as in animal experiments, participants learned only when feedback was immediate. A second experiment confirmed that the effects of the delay depended on how many responses had to be held in working memory: the greater the memory load, the poorer the learning. The results point to the importance of activity during a delay on learning; implications for the teaching of motor skills are discussed.

Satanism as a response to abuse: the dynamics and treatment of satanic involvement in male youths.

Male youths from abusive family environments may be particularly vulnerable to recruitment into satanic cults. Families that are abusive, devalue or invalidate the abused child's feelings, blame the child for the family's problems, and view the world in rigidly moralistic terms create environments in which the youths are likely to identify with the aggressor and label themselves as evil. These youths, who may have poor social skills and feelings of anger, low self-esteem, self-blame, depression, powerlessness, and isolation as a result of the abuse, may use satanic involvement as a means of legitimizing their experience and differentiating from a negatively enmeshed and/or abusive family system. In this paper, the etiological factors and treatment approaches of ten hospitalized boys who had voluntarily involved themselves in repeated group satanic activities during their adolescence are described, and two case illustrations are given. Recommendations for understanding and treating such cases are provided.     

Dialogic argumentation as a vehicle for developing young adolescents' thinking

Argumentive reasoning skills are featured in the new K-12 Common Standards (Common Core State Standards Initiative, 2010), yet with little said about their nature or how to instill them. Distinguishing reasoning skills from writing skills, we report on a multiyear intervention that used electronically conducted dialogues on social issues as the medium to develop argumentive reasoning skills in two cohorts of young adolescents. Intervention groups demonstrated transfer of the dialogic activity to two individual essays on new topics; argument quality for these groups exceeded that of comparison groups who participated in an intervention involving the more face-valid activity of extensive essay writing practice, along with whole-class discussion. The intervention group also demonstrated greater awareness of the relevance of evidence to argument. The dialogic method thus appears to be a viable one for developing cognitive skills that the comparison-group data show do not routinely develop during this age period.     

Evaluation of family therapy trainees: acquisition of cognitive and therapeutic behavior skills

In this study, which describes the evaluation of a structural family therapy training program, we developed an evaluation procedure that can be used with other similar training programs. Trainees were evaluated before and after training as to their improvement in cognitive, case-planning and in-therapy intervention skills. Results suggest a progression of skill learning, beginning with cognitive understanding, followed by case planning, and then intervention skills. Though trainees made significant progress in cognitive and planning skills, this was not the case with intervention skills. Trainees' self-evaluations were similar to their results on other measures.     

Motor learning and ultradian sleep cycle: an electroencephalographic study of trampoliners

Evidence from both animal experiments and human studies suggests that sleep might be involved in neuronal and biochemical mechanisms of learning. In the present study distinct changes in the temporal organization of sleep stages were observed in 8 volunteers participating in a training course in trampolining. Since trampolining requires the acquisition of unaccustomed motor skills, it can be regarded as a special case of motor learning. Subjects who were able to acquire new motor skills during distinct training units in trampolining showed an increase in sleep-cycle period and mean duration of REM and slow-wave sleep. These results are discussed with respect to biochemical mechanisms which may be involved in both learning and organization of sleep stages.     

Teaching chained skills in a non-school setting using a divided half instructional format

This investigation evaluated the use of dyadic instructional arrangements in teaching chained skills to four students with moderate mental retardation. Each instructional dyad consisted of two students. Each of the three cooking skills was divided into two equal parts, and each student in a dyad received direct instruction on one part of the task analysis during each instructional session. During the following session, the two parts were reversed and a student received instruction on the second part. A constant time delay procedure was used to teach the targeted skills in an off-campus setting. A multiple probe design across skills and replicated across students evaluated the effectiveness of the instructional procedure and teaching arrangement. Results indicate that each of the four students learned the three cooking skills. Implications for future research are discussed.     

The influence of practice on the development of motor skills in pianists: a longitudinal study in a selected motor task

A longitudinal study was conducted to investigate the influence of practice on the long-term development of expert pianists' motor skills in a relevant musical context. Temporal evenness in standardized scale playing was assessed twice in 19 pianists within an average time interval of 27 months. Questionnaires were used for retrospective assessment of practice quantity and several qualitative parameters related to practicing of scales. The development of temporal evenness in scale playing over the follow-up period correlated with the practice time accumulated during that period and with the average daily practice time. Expert pianists with an average daily practice time of 3.75h or more showed an improvement of performance in this selected motor skill. No significant association was observed between motor skill development during the follow-up period and the content of practice. Stepwise linear regression revealed a model predicting 43% of the variance of motor skill development, with practice time accumulated during the follow-up period as the only predictor. It was concluded that, in expert pianists, maintenance of motor skills in the selected motor task was strongly influenced by practice quantity.     

Reported use of a Japanese accent to promote fluency

This report describes a case study of a young adult man who reportedly adopted an imitation of a Japanese accent as a means of eliminating symptoms of stuttering. Prolonged unfilled pauses and altered stress patterns were key features of his deviant speech pattern. Following an extensive evaluation of his communication skills and case history, it was determined that his unusual speech pattern may have resulted from an identification with a small peer group of Japanese exchange students with whom he felt comfortable. This identity (including his accent) may have provided him with self-confidence he lacked as a teenager, thus enabling him to communicate with more assurance and confidence. It was conclude he was neither a stutterer nor a clutterer.     

Teaching social skills to emotionally disturbed adolescent inpatients

A social skills training program was evaluated with emotionally disturbed adolescent inpatients. The targeted social skills required an action or reaction within six skill areas. The program was adapted from a commercially available social skills training game that features the use of response specific feedback, self-monitoring, individualized reinforcers, and individualized performance criteria. A peer conducted the baseline and posttraining sessions while the training was conducted by an adult who had no previous interactive history with the subjects. A multiple baseline design across groups demonstrated that the program increased appropriate responding in all skill areas and that these effects generalized during the posttraining peer conducted sessions. A generalization test indicated that the subjects used their newly learned skills with a novel adult outside the training setting. The program appears quite applicable to emotionally disturbed adolescents since it targets skills in a variety of areas and employs standardized procedures to enhance replicability.     

Assessment of Quality of Outcomes within a Local United Way Organization: Implications for Sustaining System Level Change

This paper provides a historical case study of efforts to implement and sustain "outcomes based funding" in a large United Way system in Central Ohio. The case study describes how community practitioners employed specific strategies to promote sustainability. The use of these strategies corresponds to several techniques suggested in the sustainability literature. This case study is offered as a means of considering how practitioners helped sustain the shift to outcomes based funding within the United Way system. In addition, this case study demonstrates how skills related to implementation and sustainability might be transferred to other situations where practitioners are interested in promoting change within large organizations and/or communities. The authors suggest that skills related to implementation and sustainability are essential to community practice.     

Changes in self-reported driving behaviour following attendance at a mature driver education program

A telephone survey was conducted with 367 drivers aged 55–94 years who had voluntarily attended the 55 Alive/Mature Driving education program one-and-one-half to four years prior. 55 Alive/Mature Driving is a classroom delivered program that presents information on the effects of aging on driving, general rules of the road and road signs, and strategies for reducing driving risk. The survey contained both open-ended and closed questions and asked respondents to recall what they had learned in the course, and how their driving behaviour had changed as a result of attending. Results showed that 20% of respondents, especially older men, were urged to attend the course by a spouse or other. Types of information recalled from the course fell into seven main categories: need for increased vigilance; road rules and road signs; visual skills; self-awareness; maneuvers; safe speed; and space margins. Three quarters of participants said they changed their driving habits as a result of attending the course including: increased awareness and visual skills; changes in attitude; improved speed and space margins; avoidance of hazards; using more caution; obeying road rules; and improved vehicle maneuvers. Men were more likely to report their driving skills had improved since taking the course, and older men reported significantly higher mean comfort scores with their driving. Comments about the course’s delivery underscored the importance of providing opportunities to interact, an environment where participants felt safe in expressing their views, and an opportunity to practice.
