The Adolescent Activities Checklist: Reliability,standardization data,and factorial validity

This study was conducted to provide standardization data and information on the reliability and factorial validity of the recently developed Adolescent Activities Checklist (AAC). A total of 563 adolescents in grades 7 through 12 served as subjects. Significant main effects for gender, race, and grade were obtained in a multivariate analysis of variance. On the basis of this information, standardization data were established for these three variables. Further investigation indicated that the internal consistency of the AAC was high. In addition, results of a principal components analysis conducted on the frequencies of the Unpleasant and Pleasant Activities subscales revealed four and three factors, respectively. For unpleasant activities, the major dimensions were found to occur in three situations-namely, social interactions, family situations, and school situations. Stressful events also occurred as one of the four unpleasant activities dimensions. For pleasant activities, three dimensions appeared: heterosocial behavior, reinforcing interpersonal situations, and social reinforcement.     

Part-list recall following part-whole learning

Following five trials of part-list free recall learning and six trials of whole-list free recall learning, Ss were asked to recall the part-list items on two successive trials. Experimental Ss whose whole list contained all of the part-list items recalled more part-list items than did control Ss whose whole list contained none of the part-list items. The data are inconsistent with current notion of subjective organization.     

Motivational and neuroanatomical specificity of hypodipsia for aversive solutions produced by medial preoptic injury to the rat.

Bilateral medial preoptic lesions in rats dramatically lowered the rejection threshold for quinine-adulterated water but not for food in 24-hr forced-choice tests. The detection threshold for quinine in a two-bottle choice test, however, was unaffected by the medial preoptic lesion. Bilateral septal and lateral preoptic lesions had no effect on any quinine-adulteration tests. The enhanced rejection of quinine-adulterated water in a forced-choice test by medial-preoptic-damaged rats was also observed after 24-hr of water deprivation. Furthermore, the plasma osmolality of medial preoptic rats was significantly elevated above controls after 24-hr of water deprivation. These findings were interpreted as suggesting that a medial preoptic lesion produces a deficit in thirst-motivated behavior.     

Relations among self-reported depressive symptoms in clinic-referred children versus adolescents.

Although there is consensus regarding the existence of childhood depression, disagreement remains as to whether symptoms are developmentally isomorphic. Previous studies focused on developmental differences in symptom levels; analyses of relations among symptoms may be more appropriate, however. Here both approaches were used to compare the Children's Depression Inventory responses from 1,030 clinic-referred children and adolescents. Four of nine symptom categories showed significant developmental differences in their correlations with total score. Externalizing behavior and guilt were more strongly related to depression in children than adolescents; affective symptoms and concerns about the future showed the reverse pattern. Results illustrate the importance of considering relations among symptoms as well as differences in symptom levels when evaluating theoretical claims about developmental differences in the nature of clinical syndromes.     

Development and psychometric evaluation of the Primary Appraisal of Smoking Cessation Inventory.

For this study, we developed and evaluated the psychometric properties of the Primary Appraisal of Smoking Cessation Inventory (PASCI), a self-report measure designed to assess the perceived gains and losses associated with quitting smoking based on the theoretical model of stress described by Lazarus and Folkman (1984). We administered the 26-item PASCI and two other questionnaires to 244 current smokers and to 30 ex-smokers. Item analyses indicated that two items on the PASCI should be deleted due to low item-total correlations. A principal components analysis of the remaining 24 items identified two separate and independent factors, Losses and Gains, and scores on the subscales of both factors were internally consistent and stable over repeated administrations. The validity of the PASCI was established by examining the relationship between smoking status and scores on the PASCI subscales and by finding significant correlations between the PASCI and the Decisional Balance Scale (Velicer, DiClemente, Prochaska, & Brandenburg, 1985), a measure conceptually similar to the construct measured by the PASCI. We concluded that the PASCI is reliable and valid and can be used to investigate the relationship between primary appraisal and smoking cessation.     

Infants' ability to use object kind information for object individuation.

The present studies investigate infants reliance on object kind information in solving the problem of object individuation. Two experiments explored whether adults, 10- and 12-month-old infants could use their knowledge of ducks and cars to individuate an ambiguous array consisting of a toy duck perched on a toy car into two objects. A third experiment investigated whether 10-month-old infants could use their knowledge of cups and shoes to individuate an array consisting of a cup perched on a shoe into two objects. Ten-month-old infants failed to use object kind information alone to resolve the ambiguity with both pairs of objects. In contrast, infants this age succeeded in using spatiotemporal information to segment the array into two objects, i.e. they succeeded if shown that the duck moved independently relative to the car, or the cup relative to the shoe. Twelve-month-old infants, as well as adults, succeeded at object individuation on the basis of object kind information alone. These findings shed light on the developmental course of object individuation and provide converging evidence for the Object-first Hypothesis [Xu, F., Carey, S., 1996; Xu, F., 1997b]. Early on, infants may represent only one concept that provides criteria for individuation, namely physical object; kind concepts such as duck, car, cup, and shoe may be acquired later in the first year of life.     

Psychodynamic assessment of changes in children with autism under psychoanalytic treatment

In this article the authors report insights into autism developed through their extensive experience of psychoanalytic therapy with children with autism. The fi rst stages of body psychic development are seriously disrupted by this pathology, resulting in primitive anxieties of falling and of being liquefi ed. These anxieties are connected to the fragile development of body ego and of its related spatiotemporal organisation. The changes in children observed by the authors during the therapeutic process lead them to offer a psychodynamic assessment tool, which revolves principally around the development of body ego. After the initial state of 'severe autism', the authors describe three stages: the stage of 'recovery of the skin' (Bick); the established 'symbiotic phase', subdivided into 'vertical then horizontal splitting of the body ego'; and fi nally the stage of 'individuation'. First, the authors describe the principal psychoanalytic approaches to autism and refl ect on the links possible with nonpsychoanalytic work.     

Evolution,depression and counselling

In this paper a framework of evolutionary psychology is used to develop a model of depression. In this model depression is seen as not normally a biochemical illness or disorder, but instead as usually due to the person becoming trapped within a psychologically activated but unwanted and inappropriate suite of natural emotions, with the activation coming from a perception of a major decline in personal usefulness that can include failure, guilt, shame or perceived rejection. A neuropsychological observation that supports this model is described. The implications of the model for counselling with depressed clients are outlined in terms of a multi-dimensional approach, oriented around perceived usefulness. It is predicted that clients receiving such counselling will recover more rapidly and be less likely to suffer a relapse than those receiving just drugs or a form of counselling that covers fewer dimensions.
