What children can tell us about living in danger

Developmental challenges faced by children growing up in situations of chronic danger linked to community violence and communal conflict are reviewed. The concept of post-traumatic stress disorder is expanded to include situations of chronic and on-going traumatic stress associated with dangerous environments--war zones and inner city neighborhoods plagued by violence and crime. Of particular importance is the impact of chronic stress and danger on the child's world view, the child's social map, and the child's moral development. On the basis of field work in 5 war zones, the article points to the importance of adult-led "processing" of the young child's experience to his or her psychological coping and moral development. Some of the contradictions operating in such environments are explored--for example, that "fanatical" ideology may provide short-term support for adults and children but also may serve to prolong communal conflict, impede the necessary processing of experience, and increase vulnerability in the long run.

What catatonia can tell us about "top-down modulation": a neuropsychiatric hypothesis

Differential diagnosis of motor symptoms, for example, akinesia, may be difficult in clinical neuropsychiatry. Symptoms may be either of neurologic origin, for example, Parkinson's disease, or of psychiatric origin, for example, catatonia, leading to a so-called "conflict of paradigms." Despite their different origins, symptoms may appear more or less clinically similar. Possibility of dissociation between origin and clinical appearance may reflect functional brain organisation in general, and cortical-cortical/subcortical relations in particular. It is therefore hypothesized that similarities and differences between Parkinson's disease and catatonia may be accounted for by distinct kinds of modulation between cortico-cortical and cortico-subcortical relations. Catatonia can be characterized by concurrent motor, emotional, and behavioural symptoms. The different symptoms may be accounted for by dysfunction in orbitofrontal-prefrontal/parietal cortical connectivity reflecting "horizontal modulation" of cortico-cortical relation. Furthermore, alteration in "top-down modulation" reflecting "vertical modulation" of caudate and other basal ganglia by GABA-ergic mediated orbitofrontal cortical deficits may account for motor symptoms in catatonia. Parkinson's disease, in contrast, can be characterized by predominant motor symptoms. Motor symptoms may be accounted for by altered "bottom-up modulation" between dopaminergic mediated deficits in striatum and premotor/motor cortex. Clinical similarities between Parkinson's disease and catatonia with respect to akinesia may be related with involvement of the basal ganglia in both disorders. Clinical differences with respect to emotional and behavioural symptoms may be related with involvement of different cortical areas, that is, orbitofrontal/parietal and premotor/motor cortex implying distinct kinds of modulation--"vertical" and "horizontal" modulation, respectively.     

What gene-environment interactions can tell us about social competence in typical and atypical populations

Social competence is a complex human behaviour that is likely to involve a system of genes that interacts with a myriad of environmental risk and protective factors. The search for its genetic and environmental origins and influences is equally complex and will require a multidimensional conceptualization and multiple methods and levels of analysis. Behavioural genetic research can begin to address the fundamental yet complex question of how children develop social competence by uncovering the various influences on social development and disentangling variance due to multiple genes, environments and experiences. In this paper, we review the current status of research on sociability, face recognition, emotion recognition, and theory of mind (TOM)--well defined and measured constructs that are likely to be useful indices for detecting genetic and environmental influences on social competence. We also propose specific milestones as indices of further progress in the field: the development of an operational definition of the construct of social competence, the identification of social endophenotypes-psychological processes that are validly and reliably measured components of social competence, and improving specificity and homogeneity with regard to social endophenotypes within a population of study by employing 'extreme social phenotypes'. These efforts will lead to a better understanding of the specific contributions to the normal variation of social competence in the general population as well as to atypical social development.     

What clocks tell us about the neural correlates of spatial imagery

We review a series of experimental studies aimed at answering some critical questions about the neural basis of spatial imagery. Our group used functional magnetic resonance imaging (fMRI) to explore the neural correlates of an online behaviourally controlled spatial imagery task without need for visual presentation—the mental clock task. Subjects are asked to imagine pairs of times that are presented acoustically and to judge at which of the two times the clock hands form the greater angle. The cortical activation elicited by this task was contrasted with that obtained during other visual, perceptual, verbal, and spatial imagery tasks in several block design studies. Moreover, our group performed an event‐related fMRI study on the clock task to investigate the representation of component cognitive processes in spatial imagery. The bulk of our findings demonstrates that cortical areas in the posterior parietal cortex (PPC), along the intraparietal sulcus, are robustly involved in spatial mental imagery and in other tasks requiring spatial transformations. PPC is bilaterally involved in different kinds of spatial judgement. Yet the degree to which right and left PPC are activated in different tasks is a function of task requirements. From event‐related fMRI data we obtained evidence that left and right PPC are activated asynchronously during the clock task and this could reflect their different functional role in subserving cognitive components of visuospatial imagery.     

Acquiring new word meaning: What does it tell us about development

R. J. Sternberg (1984, Developmental Review, 4, 113–138) offers a thoughtful and provocative essay on how individuals acquire meanings for novel or unfamiliar nouns. The Sternberg essay, however, is incomplete on a number of grounds. By stressing general processes and specific knowledge as critical components in the acquisition of verbal concepts, for example, it overlooks two logically complementary categories—specific processes and general knowledge—and the role these play in the acquisitions in question. A second concern is that the paper blurs distinctions among development, short-term learning, and the origin/acquisition of individual differences. Finally, Sternberg is encouraged to frame the specific phenomenon described here within the context of a larger theory of intellectual development and to indicate what else this specific model can be used to explain.     

What the stories children tell can tell about their memory: narrative skill and young children's suggestibility

The authors examined the relation between children's narrative ability, which has been identified as an important contributor to memory development, and suggestibility. Across 2 studies, a total of 112 preschool-aged children witnessed a staged event and were subsequently questioned suggestively. Results from Study 1 indicated that children's ability to provide a high-quality narrative of the event was related to resistance to suggestive questions, and narrative ability appeared to supersede age as a predictor of such resistance. In Study 2, children's general language and narrative abilities were measured in addition to their ability to produce a high-quality narrative about the target event. These results replicated Study 1's findings that children's ability to produce a high-quality narrative of a previously experienced event predicted resistance to suggestion. However, the quality of children's autobiographical memory narratives predicted shifting from denial to assent. Findings are considered in light of narrative's role in memory development and underlying mechanisms that may explain children's suggestibility.     

Interactions do not only tell us when,but can also tell us how: Testing process hypotheses by interaction

Hypotheses about psychological processes are often tested using traditional mediation analysis. This analysis relies on measurement of a transmitting variable. Conducting this analysis has become almost synonymous with examining process hypotheses. An alternative strategy to mediation analysis (the Testing‐a‐Process‐hypothesis‐by‐an‐Interaction Strategy, TPIS) is illustrated here. TPIS is based on a fully experimental design whereby a hypothesized process is tested by an interaction between the hypothesized cause of an effect and a contextual variable. In the interaction term, the contextual variable allows comparison of the causal effect observed when the process is uninterrupted to the effect observed when the process is interrupted. Thus, TPIS translates a theoretical process hypothesis into a statistical interaction hypothesis that uses a fully experimental design to directly examine the hypothesized process.

Society,self, and mind in moral philosophy: The scottish moralists as precursors of symbolic interactionism

Many of the concepts central to symbolic interactionism were anticipated by the eighteenth century Scottish moralists. The symbolic-interactionist and Scottish moralist orientations both hold that society alone engenders uniquely human qualities, self arises through sympathetic interaction, and mind and self reconstruct their environments. George H. Mead's conception of thought as internal dialogue between the “I” and “me” aspects of the self and his notion of the “generalized other” were foreshadowed by some of the Scottish moralists, particularly Adam Smith. These schools differ, though, in their treatments of emotion, communication, political structures, and the origin of sympathy.     

Interpretation, psychoanalysis, and the philosophy of mind

I suggest that a conflict between two philosophical models of the mind so far unremarked in discussions of psychoanalysis is at the heart of questions about its status as a science, the objectivity of psychoanalytic interpretations, and the nature of the unconscious. In philosophy one model is embodied in the tradition of Descartes, Hobbes, Locke, Kant, among many others, which construes thought as prior to and independent of language. According to this tradition the mind is self-contained and mental contents or "ideas" are essentially subjective phenomena. It follows that knowledge of other minds and the material world is radically problematic. In the second and more contemporary model the phenomenon of meaning is dependent on interactions between minds, and between mind and the world. Since meaning is understood to be intrinsically social, so in an important sense is mind. I develop this second philosophic model, indicating its relevance for psychoanalysis. I also point out some of the contributions of psychoanalysis to philosophy of mind.     

"Come on, Jack, tell us about yourself": the growth spurt of group psychotherapy

Group psychotherapy evidenced a growth spurt in the decade of the 1930s and prior to World War II. Following upon the pioneering efforts of the psychoeducators (Pratt, Marsh, Lazell) and the writings of the early analysts (Freud, Adler, Dreikurs, Burrow), the next wave of practitioners and theorizers popularized and expounded the use of the group treatment modality in hospitals, clinics, and private practice. A review of the seminal ideas and efforts of Jacob Moreno, Louis Wender, Paul Schilder, Lauretta Bender, Alexander Wolf, and Samuel Slavson continues the historical overview begun earlier in this journal (Ettin, 1988). In a continuing effort to call up the wisdom of the past in the service of the work of the present, the emphasis in this paper will be on practical application. Representative quotes will be embedded in the text to capture the tenor of the times, and special attention will be given to (1) theoretical underpinnings such as the proposed advantages, curative variables, and therapy goals of a group treatment; (2) the basic logistics of practice, including optimum group size, composition, membership and exclusion criteria, and length, frequency, and structure of the meetings; and (3) technical considerations, such as the role of the therapist and the techniques, procedures, and processes of the ongoing group endeavor, as well as the interface between individual and group sessions. In conclusion, it will be argued that group psychotherapy matured just in time to respond to the pressing need for efficient mental treatment mandated by the coming of the Second World War.     

Demonstrations of spatiotemporal integration and what they tell us about the visual system

Five sets of displays are presented on the journal website to be viewed in conjunction with the text. We concentrate on the factors that give rise to the integration and disruption of the direction of apparent motion in two-dimensional and three-dimensional space. In the first set of displays we examine what factors contribute to the integration and disruption of apparent motion in the Ramachandran/Anstis clustered bistable quartets. In the second set we examine what factors give rise to the perception of the direction of motion in rotating two-dimensional wheels and dots. In the third and fourth sets we examine how the depth cues of shading and disparity contribute to the perception of apparent motion of opaque displays, and to the perception of rotating unoccluded displays, respectively. In the fifth set we examine how the depth cue of motion parallax influences the perception of apparent motion. Throughout, we make inferences about the roles which various parallel pathways and cortical areas play in the perceptions produced by the displays shown.     

Philosophy and the morality of abortion

ABSTRACT Abortion is a philosophically interesting issue because both sides seem so certain of their conclusions, yet the issue is at the same time clearly a derivative one. It is also highly political, and needs to be seen within the context of the growth of the women's movement. A philosophical overview of the issue in section 1 construes the central claims of the pro-choice and anti-abortion positions as moral and conceptual constructions, which extend everyday moral thinking into the area of abortion. It notes the interesting relation between such constructions and other arguments about abortion, and how this is responsible for their social and historical specificity. Section 2 defends the pro-choice position as a victory of moral sensitivity over linguistic guile. Section 3 situates the argument within the politics of feminism, and recognises the limited contribution which philosophy is able to make.
