Cluster analysis in school psychology: An example

This investigation demonstrates the use of Ward's method of cluster analysis to uncover the underlying classification structure in a group of children (N = 200) referred for psychological evaluations by their public school teachers. Data were acquired on children's intellectual development, academic achievement, and social adjustment. The cluster solution identifies six groups of children which are statistically distinct. All three measurement areas are important in distinguishing among the different groups. The six-group solution accounted for appreciable amounts (95%) of the variability in the three measurement areas. Implications for psychologists working in the schools are discussed.     

The role of exploration in win-shift and win-stay performance on a radial maze

Win-shift spatial memory tasks in a radial maze reinforce animals for avoiding previously visited rewarded arms; win-stay tasks reinforce them for returning to those arms. Win-shift tasks have generally been found much easier to perform, and this may be explained either in terms of foraging models which postulate avoidance of locations where food has been found, or in terms of the predominance of spontaneous alternation (exploration). Experiment 1 examined spontaneous alternation behavior in the radial maze as a function of whether the first visit to an arm had been rewarded or not, and showed that alternation was more probable after nonreward than after reward in both hungry and thirsty rats (a result which conflicts with the foraging account of the win-shift superiority). Experiment 2 replicated the finding that win-stay discrimination performance was inferior to win-shift. A manipulation (lengthening the delay between initial and test choices) which weakens spontaneous alternation, reduced, but did not reverse, the win-shift superiority. In Experiment 3, in order to eliminate the influence of spontaneous alternation, versions of the win-stay and win-shift tasks were devised in which, unlike the original task, all arms were familiar at the choice trial. Under those conditions win-stay was performed better than win-shift. It is concluded that spontaneous alternation plays a major role in many spatial memory tasks, and that the results can best be accounted for by combining principles of exploration and simple associative learning, without recourse to foraging models.     

A prospective naturalistic study of the impact of an intensive medical treatment on the social behavior of child and adolescent cancer patients

The impact of intensive chemotherapy and prolonged hospitalization on the social behavior of child and adolescent cancer patients was assessed. Twenty-three patients, aged 18 months to 21 years, were observed while they received chemotherapy in a protected environment or in a regular hospital room. Single-subject analyses were used to examine changes on six behaviors in relation to changes in physiological status. Fourteen patients showed significant change in the frequency of at least one behavior. Play and sleep were the behaviors most likely to change. The changes began to occur as patients experienced the systemic toxic effects of the drugs, although a dissipation of drug toxicity generally was not accompanied by a corresponding behavior change. The findings are discussed in relation to age-developmental and interindividual heterogeneity in response to treatment.     

A modern assessment of the basic forms of aphasia

A brief survey of the field of aphasia is presented. Many of the facts described in the neurological classics remain valid, but the interpretation of these facts must be altered. The basic principles of aphasia are reassessed in the light of neuropsychology. Neuropsychological analysis shows sensory (acoustico-gnostic) aphasia to be based upon an impairment in phonemic hearing. Motor aphasia breaks down into afferent (kinesthetic) and efferent (kinetic) aphasia. The former is based upon an impaired kinesthetic input into the speech functions, which results in a special type of oral apraxia. Efferent (kinetic) aphasia is based upon a breakdown in the kinetic organization of speech motor acts. Nominative (amnestic) aphasia consists of a number of forms, each based on either a weakness of visual or auditory analysis or difficulty in selection between evoked memory traces. “Transcortical motor aphasia” proves to be either perseverative aphasia, i.e., aphasia in which the dynamics of plasticity are impaired, or the result of the impairment of internal speech. The basic defect underlying “conduction” aphasia is beginning to be understood as a weakened acoustico-gnostic function or difficulties in retarding sideline associations.     

Therapeutic Utility of Discussing Therapist/Client Intersectionality in Treatment: When and How?

The impact of the therapeutic alliance on positive clinical outcomes has been established in the literature; however, literature is lacking on how the intersection of therapist and client identities influences this process. We propose that the relational intersectionality resulting from similarities or differences in therapist and client identities has the potential to impact the bonds, tasks, and goals of treatment (key components of the therapeutic alliance; Bordin, 1979) depending on how it is addressed or avoided in therapy. In this paper, we present a model containing pragmatic steps therapists can follow to navigate these conversations with clients in a way that is therapeutically beneficial and culturally sensitive and attuned. Additionally, we provide suggestions for using the proposed model to train new student therapists (or expose experienced therapists) to ideas of intersectionality and social justice by reflecting on the intersection of their own identities, acknowledging dynamics of power and oppression, and understanding how this could shape their relationship with clients.     

Mobiliser les arbitrages organisationnels pour prévenir les risques professionnels dans les espaces confinés : le cas des chantiers de réfection de canalisation en égouts

This contribution participates to the development of ergonomic contributions to the prevention of occupational risks in confined spaces, specifically in sewer pipe rehabilitation projects. The intervention deployed was structured around a participatory and collaborative approach involving all stakeholders in the project to sustainably improve the prevention of work-related accidents and musculoskeletal disorders among workers. Detailed analyses of workers’ activities coupled with a systemic analysis of the design and collective monitoring of the worksites were carried out. This made it possible to characterize the health and safety risks of site teams as products that compromise between several organizational requirements and situational constraints. Extended to the site manager, the analysis of his activity, although strategic, of anticipation and continuous design of intervention situations, proved to be limited by a vertical organization of the sites, which does not integrate his expertise. Based on the diagnosis, validated and shared by all, the prevention challenges were articulated with the performance objectives of the worksites in a perspective of co-design with and by the different hierarchical levels of the department. The intervention made it possible to collaboratively build new organizational rules that consider the concrete realities of the work of workers and site managers.     

Building self-control strength: Practicing self-control leads to improved self-control performance

Self-control performance may be improved by the regular practice of small acts of self-control.Ninety-two adults’ self-control capacity was assessed using the stop signal paradigm before they started practicing self-control and again at the end of 2 weeks. Participants who practiced self-control by cutting back on sweets or squeezing a handgrip exhibited significant improvement in stop signal performance relative to those who practiced tasks that did not require self-control. Participants who did not practice self-control believed that the tasks should improved self-control, engaged in tasks that were effortful and made self-control salient, but did not actually require self-control. Supplemental analyses suggested that only practicing self-control built self-control capacity; the improved outcomes cannot be explained by self-fulfilling prophecies, increased self-efficacy or awareness of self-control. The results may have implications for understanding the development of self-control in both children and adults, as well as clinical implications for treating disorders that involve low self-control.     

La dynamique identitaire de stagiaires immigrants : Stratégies d’acculturation et insertion dans un collectif de travail

The aim of this research was to explore reciprocal relations between acculturative strategies of immigrant trainees and their “strategies” of integration into a workgroup. The investigation of each participant’s identity dynamics served as a basis to this qualitative and exploratory study, using the IMIS (multistage social identity investigator), created by Zavalloni and Louis-Guérin (1984, 2007). In both the cases presented here, work environments echoed back to some of the main obstacles opposing to the social integration of immigrants. Therefore, part of the results revealed spontaneous emergence of adaptative strategies simultaneously linking to cultures and the profession.     

La perception parentale de la pratique du bilan psychologique de l’enfant et de l’adolescent

The psychological assessment is a widespread approach in child and adolescent psychology, but few studies have examined the experiences of the main stakeholders during this process. This study was conducted among 105 parents consulting for their child in a psychological counseling centre, and investigated by ad-hoc questionnaires the dimensions that can be involved at different moments of the assessment: expectations and perceptions, motivation for change, working alliance, and satisfaction with care. The results highlight the importance of parents’ initial representations and the quality of first contact with psychologists. This study enhances our understanding of procedural elements little studied and yet determinant for the engagement of parents in the psychological assessment and the intervention that would follow.
