Sunk Cost and Commitment to Medical Treatment

The influence of prior, irretrievable, investment (sunk cost) on commitment to medical treatment was investigated. Three studies were run investigating the influence of sunk cost in the form of money, time, and effort. A total of 637 participants (314 male) with a mean age of 19.58 years were recruited from an undergraduate population. A computer program simulated the process of arranging a course of physiotherapy. Participants invested one of three amounts of sunk cost (under budget, on budget, or over budget) into arranging sessions with a chiropractor. Participants then decided how much time they wished to commit to these chiropractor sessions or to an alternative treatment with a better chance of success. Results revealed a significant effect of invested money, a significant effect of invested effort, but no effect of invested time. Invested money produced a sunk cost effect, while invested effort appeared to exert influence via cognitive dissonance. The implications for healthcare decision-making are discussed.     

Mothers' Parenting and Young Economically Disadvantaged Children's Relational and Overt Bullying

We examined links between mothers' parenting and children's relational bullying and overt bullying in a sample of children attending a Head Start program. Mothers completed surveys and face-to-face interviews. Head Start teachers completed assessments on children. Results indicated that a small percentage of children in the sample was rated by teachers as engaging in relational bullying “frequently to almost always,” and slightly over half of the sample was rated by teachers as engaging in relational bullying “occasionally to about half of the time.” Similar results were found for the frequency with which children engaged in overt physical bullying. Regarding mothers' parenting, maternal empathy was most strongly correlated with both children's relational bullying and overt physical bullying. In addition, mothers' inappropriate developmental expectations for children and mothers' need to exert power over children rather than grant them independence were related to children's relational bullying. A composite variable for mothering predicted 11% of the variance in children's relational bullying. No gender differences were found for children's relational bullying and children's overt bullying.     

Life cycle and loss--the spiritual vacuum of heroin addiction

This research studied the function of heroin addiction as a family-learned method of coping with death, separation, and loss across the life cycle. Heroin addicts, psychiatric outpatients, and normal students were given an extensive interview and test battery to determine the incidence of loss of family members and significant others. Because the impact of death is often overcome through religious rituals, this study also investigated the subjects' perception of their families' religious values and orientation to life's meaning and purpose. Results indicate that the incidence of death differs significantly across groups and that addicts have a distinct orientation to death, are more suicidal, and have more premature and bizarre death experiences. During childhood they have more family separations, and they tend to develop a distinct pattern of continuously separating from and returning to their families. They are also less likely to have a clearly defined purpose in life. A subset of parents from each group were also interviewed and tested, and these results support the theory of the intergenerational transmission of behavior.     

Empty nest,cohort, and employment in the well-being of midlife women

Whether the empty-nest experience has positive or negative consequences for women's well-being at midlife may depend on their historical cohort membership and employment status. In this study, it was posited that the empty nest was likely to be a negative experience among the particular cohort of women (Cohort II) who reached adulthood during the period of strong societal emphasis on women's maternal role known as the feminine mystique, would be experienced positively among the earlier cohort (Cohort I) who as young adults were encouraged to enter the labor force during World War II. Analyses of covariance tested the relationships among empty-nest status, cohort membership, and employment status, and three measures of psychological well-being, adjusted for age, education, and marital status. The results of this study show that cohort and employment each have important independent associations with women's well-being at midlife, but that the experience of the empty nest depends on these two factors, especially cohort experiences.The authors wish to thank Joseph Veroff, Elizabeth Douvan, and Richard Kulka for the use of the data from The Study of Modern Living, and Joseph Veroff for comments on an earlier version of this paper.     

Token economy: patient and staff changes

A token economy program conducted with severely regressed, “backward” state hospital patients is described. An evaluation of the effects of the reinforcement program after one year has revealed substantial gains in patient eating, grooming, and dressing behavior and involvement in activities on and off the ward. In addition, several measures of staff attitudes toward patients evidence meaningful gains in staff expectations about the treatability of patients and the degree of the latters' psychological deficit.     

Assessing pavlov’s impact on the American conditioning enterprise

In this article, the visibility of Pavlov and of Watson in American psychology are compared, and the periods of their respective influence are specified with greater precision than is afforded by merely impressionistic methods. The author also critically examines the possibility that the early history of the American classic-conditioning enterprise involved a succession of two phases: a Watsonian/speculative phase and a Pavlovian/empirical phase. In conclusion, the author assesses the possibility that the publication of Pavlov’sConditioned Reflexes (1927) “stimulated” scholarly work on Pavlovian conditioning, and finds this proposition lacking empirical support.
