Modifying food purchases in supermarkets with modeling, feedback, and goal-setting procedures

We compared several procedures designed to modify consumer food purchases with the objectives of reducing fat and increasing carbohydrate content, and reducing dollar expenditures on food. Participants were 126 volunteer community households which, after a 7-week baseline period, were randomly assigned to video-modeling, video-modeling-feedback, video-lecture, video-lecture-feedback, participant-modeling, video-modeling-discussion, and control conditions. The main dependent measure was a weekly record of food purchases, convertible to percentages of nutrients and dollar expenditures. Results indicated that modeling-feedback and participant-modeling procedures were most effective (e.g., 6% reduction of total fat consumption, 19% dollar savings). Strategies to refine and automate modeling and feedback in supermarkets that may benefit consumers, corporations, and government are discussed.     

Bulimia—Its dynamics and treatment: The case of an adolescent male

Male bulimics are rare. Through the analysis of a case of an adolescent man, the causation of this eating disorder from the viewpoint of both nature and nurture is explored. How the pathology develops from defects in early object relationships is explained in detail. Treatment strategies and practical use of the information gleaned are fully elaborated. This is a pragmatic and helpful paper for clinicians on all levels.     

Anxiety and locus of conflict in delinquents

The State-Trait Anxiety Inventory for Children (STAIC) and the Children's Manifest Anxiety Scale (CMAS) were administered to 54 juvenile delinquents (27 males, 27 females). Ratings on locus of conflict were also obtained. The STAIC A-State scale was significantly correlated with internalization but not with externalization or the total maladjustment index. Neither A-Trait nor the anxiety portion of the CMAS was correlated with locus of conflict. All measures of anxiety were significantly correlated with each other. Boys were rated as more internal, external, and maladjusted than girls despite the fact that girls reported more subjectively experienced anxiety.     

Toward a cognitive-behavioral model of child psychopathology and a critique of related interventions

A cognitive- behavioral model recognizes the interdependencies of cognitive, affective, social, developmental, and behavioral factors in the etiology and remediation of childhood psychopathology. The model is concerned with the cognitive distortions and deficiencies that surround behavioral events and emphasizes the combination of treatment strategies with the therapist as a remediation organizer. Recommendations are made regarding treatment expectations, the specificity of the cognition-disorder relationship, the quality of the application of the training, and the need for further involvement of the child in the therapeutic curriculum.Portions of this paper were adapted from an address given at the Instituto Nacional De Salud Mental Honorio Delgado-Hideyo Noguchi, Lima, Peru, December 1984. Portions were also presented as part of a colloquium at Rutgers University. I wish to thank Kelly Bemis for her helpful comments on an earlier draft of this paper.     

The effect of methyl parathion on susceptibility of bobwhite quail (Colinus virginianus) to domestic cat predation

Bobwhite quail (Colinus virginianus) that received either 0, 2, 4, or 8 mg/kg methyl parathion (O,O-dimethyl o-p-nitrophenyl phosphorothioate) treatment were investigated as to their susceptibility to predation by a cat (Felis domesticus) predator. Four hours after receiving methyl parathion (MP), physical activity levels were monitored in quail and included the number of seconds spent still, walking, running, or flying before and after a cat was introduced into an experimental arena. The cholinesterase (ChE) activity for each quail on experiment was determined. Quail that were captured exhibited significantly greater inhibition of brain ChE activity and spent significantly more time being still than noncaptured birds. Birds receiving MP at 8 mg/kg spent more seconds being still than those in other treatment groups and had ChE activity reduced to 42.8% of normal activity. There was a tendency for quail at increasing treatment levels to be more susceptible to capture by the cat predator. The neurological and behavioral effects of methyl parathion may have important ecological ramifications.
