Many kinds of objects and events in our world have a strongly time-dependent quality. However, most theories about concepts and categories either are insensitive to variation over time or treat it as a nuisance factor that produces irrational order effects during learning. In this article, we present two category learning experiments in which we explored peoples’ ability to learn categories whose structure is strongly time-dependent. We suggest that order effects in categorization may in part reflect a sensitivity to changing environments, and that understanding dynamically changing concepts is an important part of developing a full account of human categorization. 相似文献

Psychic processes underlying suicidal behaviours during adolescence and their evolution are explored. A longitudinal study was conducted of thirty adolescent patients hospitalised following a suicide attempt. Clinical interviews were used combined with the Rorschach Test and the Thematic Apperception Test (TAT) a few days after the suicide attempt and one year later. Results initially showed common forms of psychic adjustment: melancholic identifications were linked to an excessive dependence on objects. One year later, these forms of psychic adjustment changed: for many adolescents, the melancholic identifications shifted and self-image improved. The emergence of representations of murder fantasies immediately after the suicidal behaviour allowed a possible transformation of violence into symbolisation. A case study illustrates these psychic changes. 相似文献

Neuroendocrine dysfunction is hypothesized to be an early emerging vulnerability marker for depression. We tested whether the main and interactive effects of maternal psychopathology and early child temperamental vulnerability for depression assessed at age three predicted offspring’s basal cortisol function at age 6 years. 228 (122 males) children participated in the baseline and follow-up assessments. At age three, maternal lifetime psychopathology was assessed with a diagnostic clinical interview, and child temperamental positive affectivity (PA) and negative affectivity (NA) were assessed using laboratory observations. At age six, children’s waking and evening cortisol were assessed on 2 days. Maternal lifetime anxiety predicted offspring’s higher morning cortisol at age six. Child temperamental NA at age three predicted higher evening cortisol at age six. There was a significant interaction between maternal lifetime depression and child temperamental PA at age three in predicting offspring’s morning cortisol at age six. For the offspring of mothers with lifetime depression, higher PA at age 3 predicted lower morning cortisol at age 6. These findings highlight the importance of examining the main and interactive effects of maternal psychopathology and early child temperamental vulnerability in predicting the development of offspring’s stress physiology. Findings hold significance in identifying etiological mechanisms of risk and delineating the complex developmental pathways to psychopathology. 相似文献

Anxiety disorders are the most frequently diagnosed form of psychopathology in children and often result in chronic impairment that persists into adulthood. Identifying neurobehavioral correlates of anxiety that appear relatively early in life would inform etiological models of development and allow intervention and prevention strategies to be implemented more effectively. The error-related negativity (ERN), a negative deflection in the event-related potential at fronto-central sites approximately 50 ms following the commission of errors, has been consistently found to be larger among anxious adults. The current study sought to extend these findings to even younger individuals: the ERN was elicited by a Go/NoGo task in 48 six year-old children with a clinical anxiety disorder assessed by diagnostic interview and 48 age-matched controls. In addition to child anxiety disorder, the ERN was examined in relation to maternal history of anxiety disorder, which was previously related to a smaller ERN. Anxious children were characterized by a larger (i.e., more negative) ERN and maternal history of anxiety disorder was associated with a smaller ERN. Thus, the relationship between an increased ERN and clinical anxiety is evident by age 6, and this effect appears independent from an opposing influence of maternal anxiety history on the ERN. These findings support the ERN as a promising neurobehavioral marker of anxiety, and implications are discussed. 相似文献

Children with autism spectrum disorders (ASD) experience high rates of anxiety, sensory processing problems, and gastrointestinal (GI) problems; however, the associations among these symptoms in children with ASD have not been previously examined. The current study examined bivariate and multivariate relations among anxiety, sensory over-responsivity, and chronic GI problems in a sample of 2,973 children with ASD enrolled in the Autism Treatment Network (ages 2–17 years, 81.6 % male). Twenty-four percent of the sample experienced at least one type of chronic GI problem (constipation, abdominal pain, bloating, diarrhea, and/or nausea lasting three or more months). Children with each type of GI problem had significantly higher rates of both anxiety and sensory over-responsivity. Sensory over-responsivity and anxiety were highly associated, and each provided unique contributions to the prediction of chronic GI problems in logistic regression analyses. The results indicate that anxiety, sensory over-responsivity and GI problems are possibly interrelated phenomenon for children with ASD, and may have common underlying mechanisms. 相似文献

This article takes as its starting point a paper by Hugo Bleichmar presented at the 2003 Joseph Sandler Research Conference on Depression. The author argues in favour of viewing depression in a broad perspective. The Freudian prototype of “guilty depression” represents only one of many pathways leading to depressive states. Psychoanalytic understanding of depression should represent a multidimensional approach, characterised by interacting determinants, both internal and external. In clinical practice, this would imply an attitude of greater freedom and flexibility in the analyst. The paper compares the psychoanalytic account of depression with that given by the cognitive approach. It is argued that within a diverse research field, where depression is studied from different angles—as a disorder of the brain and in terms of cognitive deficits—the contribution of psychoanalysis is that depression is most usefully studied at the level of psychological causation. The psychoanalytic understanding of depressive states in terms of unconscious interpretation and meaning of experience represents a distinct contribution. Implications of viewing depression as an “illness” are discussed. 相似文献

Although goal conflict is an important part of classic and contemporary theories of motivation, the correlates of goal conflict are not well understood. We identify and distinguish conflicting and facilitating goals, and assess relations with goal attainment and psychological well-being in a short-term, prospective study design. Results from multilevel models demonstrated that individuals with greater conflict were less successful in attaining their goals, but the goals they failed attain were not necessarily the ones in conflict. People who experienced goal conflict tended to be ruminative and hesitant, and reported greater levels of negative affect and increases in depression, anxiety, and psychosomatization. People who experienced goal facilitation reported greater levels of positive affect, life satisfaction, and successful goal attainment. This study identifies several implications of holding conflicting and facilitating goals, but also points to a theoretical inconsistency pertaining to goal conflict. Namely, conflicting goals may not be inherently less attainable than nonconflicting goals. We argue that distinguishing between goal- and person-level factors is essential for understanding goal striving. 相似文献

Going beyond previous studies on satisfaction in pursuing approach versus avoidance goals, the current study is the first to examine individual satisfaction in pursuing approach and avoidance goals as determined by regulatory fit between type of goal and type of strategy. Specifically, the present study shows that people with approach goals have greater satisfaction when they use an approach strategy rather than an avoidance strategy. People with avoidance goals have greater satisfaction when they use an avoidance strategy rather than an approach strategy. In addition, we explored how individual differences in the Behavioral Activation System and the Behavioral Inhibition System influenced reactions to approach and avoidance goals and strategies. 相似文献

Cross‐situational word learning, like any statistical learning problem, involves tracking the regularities in the environment. However, the information that learners pick up from these regularities is dependent on their learning mechanism. This article investigates the role of one type of mechanism in statistical word learning: competition. Competitive mechanisms would allow learners to find the signal in noisy input and would help to explain the speed with which learners succeed in statistical learning tasks. Because cross‐situational word learning provides information at multiple scales—both within and across trials/situations—learners could implement competition at either or both of these scales. A series of four experiments demonstrate that cross‐situational learning involves competition at both levels of scale, and that these mechanisms interact to support rapid learning. The impact of both of these mechanisms is considered from the perspective of a process‐level understanding of cross‐situational learning. 相似文献

Since its formulation by Bleuler in 1911, the generalisation of the term ''autism'', mainly due to its use by Kanner in 1943 and its remake by authors of Kleinian inspiration, implies problems which mislead us, blurring our perception and understanding of clinical realities. Our psychoanalytical possibilities can be enlarged by a clear knowledge of the history of psychoanalysis, a dynamic approach to psychiatric classification and to problems related to our conception of the setting. On the basis of a case history the author shows how a child and its family worked through major autistic symptoms and proposes new approaches to some psychoanalytical concepts. 相似文献
