The reduplicative babbling of five French- and five English-learning infants was examined for evidence of language-specific rhythmic patterns. Three types of patterns were examined: final-syllable lengthening, timing of nonfinal syllables, and number of syllables per utterance. Both English and French exhibit final-syllable lengthening but, because of variable word stress, English tends to lengthen nonfinal stressed syllables, as well as final ones. Thus French final-syllable lengthening is more salient because it is the only regular source of lengthening. There is also some indication that the magnitude of final syllable lengthening is greater in French than in English. In addition, French nonfinal syllables, which are not subject to English variable word stress, are generally equal in length, whereas English tends to have more irregularly timed nonfinal syllables. Finally, French breath-groups often contain as many as four to six syllables, whereas intervals between stressed syllables in English rarely contain more than three syllables. The reduplicative babbling of the French and American infants showed characteristics of the ambient language. In particular, the babbling of the French infants showed a significantly higher percentage of final-syllable lengthening than that of the American infants. The magnitude of their final-syllable lengthening was also greater. The French infants also produced significantly more reduplicative babbles that were four or more syllables in length. Finally, the nonfinal syllables of the French infants tended to be more regularly timed than those of the American infants, although this pattern emerged only in the later stage of the infants' reduplicative babbles.

Corsi's block-tapping task was given to 30 normal subjects and 38 Alzheimer-type demented patients following two different procedures. The first is the most widely standardized (scoring criterion: 3 correct reproductions out of 5 sequences), while the second is more lenient since it does not require subjects to replicate a certain performance three times. Demented patients' scores were lower than those of controls in both conditions, and scores on the two tasks were significantly correlated for patients and controls. However, the requirement of replicating the visuospatial memory performances was more detrimental for demented patients than for controls so the two procedures cannot be considered equivalent.
This article discusses the application of interpersonal process-oriented group psychotherapy to offender populations. Group psychotherapy with offenders presents problems not encountered with other populations; thus, applying the group method requires special considerations. The particular focus of this article is on the relevance of therapeutic factors in group work with offenders, group process as it applies to work with offenders, and work with difficult clients.

Greater manual dexterity and greater conceptual knowledge of tool use represent two main features that distinguish humans from other primates. Studies of human brain lesions suggest that the left hemisphere (at least in right-handed people) includes a system for processing manual skills that is specialized for tool use that interacts with another system involved more with conceptualizing, planning, and accessing knowledge associated with tool use. Growing evidence from recent neuroimaging studies supports this organization, and studies have begun to highlight specific brain regions and pathways that may be necessary for tool use. This review compares and summarizes results from 64 paradigms published over the past decade that have examined cortical regions associated with tool use skills and tool knowledge. A meta-analysis revealed cortical networks in both hemispheres, though with a clear left hemisphere bias, which may be organized to optimally represent action knowledge. Portions of this network appear to represent part of a system that is tightly linked with language systems, which is discussed together with the effects that handedness may have on the cortical organization for tool use.
Psychological preparation for stressful medical procedures is becoming more and more common, and health educators frequently design and implement many of these programs. This article summarizes many of the issues relevant to these patient education programs. Individual differences among patients and their differential responses to types of interventions are emphasized, and descriptions of information provision, skills training, relaxation training/desensitization, modeling, self-statement modification interventions are provided.
Early intervention is an area of intense current interest for parents and professionals. This article describes a mainstream National Health Service (NHS) approach to early intervention, developed at the Scottish Centre for Autism. The aims of treatment are to improve the child's early social communication and social interaction skills, leading to the potential development of play and flexibility of behaviour. This is achieved by 1:1 intensive treatment by trained therapists, and a schedule of parent training. The treatment protocol incorporates a child led approach; the use of imitation as a therapeutic strategy; using language contingent on activities; and the introduction of flexibility into play and social exchanges.
A classroom-based intervention study aimed to explore whether it was possible to teach children with autism and additional learning difficulties to use symbolic pretend play. Five children with autism were involved in a 4 month intervention that used structure, affect and repetition. The intervention progressively faded out the structuring over three phases. All the children were able to use some symbolic acts within play. The study suggests that some of the symbolic play was not the result of replicating previously modelled examples but was spontaneous and novel.

The present study investigated the influence of developmental level on interaction and imitation in infants and young children with autism on the basis of family videos and filmed consultation. The sample comprised 18 children with autism divided into groups according to their developmental quotient (DQ>50 and DQ<50). A quantitative evaluation was performed on video observations at four periods (10-12 months, 16-18 months, 24-26 months, after 4 years) using scales appropriate for the evaluation of interaction and imitation impairments. The findings showed that, at a very early age, infants later diagnosed as having autistic disorder show different intensities of interaction and imitation deficits according to developmental level.

Psychodrama, a method of human relations training and psychotherapy, is traced from its creation by Moreno fifty years ago to its present resurgence with the growth of 'humanistic' psychology. The basic techniques are described, together with Moreno's concepts of social interaction, e.g. encounter, spontaneity, the moment, cathersis and role playing. Its uses and limitations are discussed briefly.
Three patients attempted suicide by burning in one ward of a psychiatric hospital in a period of less than 1 month. No such attempts had occurred there in the previous 9 years. The three patients were schizophrenics with depressive features who occupied the same room in the ward. It seems reasonable to suggest that at least the choice of method and the timing of these suicide attempts were influenced by imitation. Hospital staff should be especially aware of the influence of imitation in suicide in order to avert such undesired epidemics.

An analysis of the temporal distribution of 115 in-patient suicides that occurred in two Swiss psychiatric hospitals in the years 1977-86 failed to reveal any statistically significant clustering of suicides. Thus, the modelling effect does not generally play a decisive role in psychiatric in-patient suicide.
