Insensitivity to future consequences following damage to human prefrontal cortex

Following damage to the ventromedial prefrontal cortex, humans develop a defect in real-life decision-making, which contrasts with otherwise normal intellectual functions. Currently, there is no neuropsychological probe to detect in the laboratory, and the cognitive and neural mechanisms responsible for this defect have resisted explanation. Here, using a novel task which simulates real-life decision-making in the way it factors uncertainty of premises and outcomes, as well as reward and punishment, we find that prefrontal patients, unlike controls, are oblivious to the future consequences of their actions, and seem to be guided by immediate prospects only. This finding offers, for the first time, the possibility of detecting these patients' elusive impairment in the laboratory, measuring it, and investigating its possible causes.     

The envious will to power

Envy, from Klein's perspective, is an inherent hatred of goodness that seeks to destroy love, creativity, and life itself. Devoid of constructive value, envy becomes an evil to be restrained or renounced, rather than a potential to be understood or developed. Confusion with evil can be avoided if envy is seen as a defence against the impact of 'otherness' and the greatness of 'others' rather than an inherent hatred of goodness. From this perspective envy emerges as a desperate attempt to preserve one's unique sense of self against the terror of non-being.     

The effect of sampling error on convergence,improper solutions,and goodness-of-fit indices for maximum likelihood confirmatory factor analysis

A Monte Carlo study assessed the effect of sampling error and model characteristics on the occurrence of nonconvergent solutions, improper solutions and the distribution of goodness-of-fit indices in maximum likelihood confirmatory factor analysis. Nonconvergent and improper solutions occurred more frequently for smaller sample sizes and for models with fewer indicators of each factor. Effects of practical significance due to sample size, the number of indicators per factor and the number of factors were found for GFI, AGFI, and RMR, whereas no practical effects were found for the probability values associated with the chi-square likelihood ratio test.James Anderson is now at the J.

Systematic bias in successive movement repetitions

In three separate studies, independent groups of subjects made either 10 subjectively defined steps of the same length, 10 subjectively defined linear arm movements of the same extent, or 10 successive movements of a single experimenter defined linear arm movement. In each case, the repetitions of these movements became increasingly longer. This is an initial report of what may be a ubiquitous phenomenon.     

Why families are not like swamps,solar systems,or thermostats: Some limits of systems theory as applied to family therapy

Family systems theory presents an answer to the riddles of mental disorder and human functioning that stands in marked contrast to other prevailing views based on linearity and traditional science. At this stage of its development, the family systems view does not provide an internally coherent, predictive, or unifying theory about humans and their problems. Further, it tends to both undercontextualize and overcontextualize behavior, substitutes blaming the family for blaming the victim, reifies and anthropomorhizes the systems metaphor, dismisses such concepts as power and responsibility, and discourages research. As one theoretical and clinical perspective among many, however, it can be helpful and eye-opening.Based on a paper presented at the Forty-fifth Annual Conference of the American Association for Marriage and Family Therapy, Chicago, 1987.     

Tigers are something else: A case for family play

This paper is an attempt to bridge the two worlds of family therapy and filial play therapy, introducing the complementary idea of play in therapy. Family play therapy challenges the idea that play is only useful in the treatment of children. Clinical examples are given and uses of play are discussed, including evaluation, play as a therapeutic tool, and the development of themes. The authors believe that therapists who are willing to be playful offer their clients a new world of therapeutic experiences.     

Single parenting: Interventions in the transitional stage

Following divorce or separation, many mother-headed families need to mourn losses, including reduced economic resources. They need to reestablish family rituals, confront such issues as time management and structural changes that can result in scapegoating or over-reliance on a parental child. Normalizing difficulties associated with parenting is important because single parents tend to internalize societal attribution of family difficulties to inadequate family structure rather than developmental stages, limited economic resources, and negative expectations about the capacity of women to head families.     

Beyond home-based family intervention: A multi-family approach toward change

A growing specialty area in the mental health field involves working with emotionally disturbed youth and families-at-risk by providing services in the context of the home environment. A review of the literature provides documentation for family systems, social learning, and ecological interventions with at-risk families receiving home-based intervention but there is an absence of material on the use of multi-family groups with this population. The purpose of this article is to outline the implementation of a multi-family therapy (MFT) component for home-based programs serving at-risk families. Advantages and disadvantages when using MFT are also addressed.The authors are grateful to Linda Pannell for her helpful comments on drafts of this article.
