Delay of gratification: impulsive choices and problem behaviors in early and late adolescence

High school students were offered a monetary incentive for participating in research. They were given a choice between a smaller fee immediately or a larger fee one week later. Compared to students who delayed gratification, those who chose the immediate fee showed more self-regulatory deficits. They showed greater involvement with cigarettes, alcohol, and marijuana, had a poorer self-concept and underperformed academically. A replication study with middle-school students and different reward parameters yielded equivalent results. Younger adolescents who chose the immediate monetary incentive showed a similar pattern of problem behaviors as the high school students. The findings indicate that this simple choice-delay procedure yields an unobtrusive behavioral measure of self-regulation and offers a developmentally appropriate extension of the delay-of-gratification paradigm for use with older children and adolescents.     

Cancer Problems in Living and Quality of Life After Bone Marrow Transplantation

This study was conducted to develop an objective problems-in-living scale to identify the needs of cancer survivors after a demanding treatment such as bone marrow transplantation (BMT). A total of 99 adult BMT survivors completed questionnaires containing the 29 items included in the Cancer Problems-In-Living Scale (CPILS). These BMT survivors were most concerned about return of their illness or relapsing, the future, fatigue, not physically being able to have sexual intercourse, changes in their physical appearance, being concerned about infection and crowds, difficulty in obtaining adequate insurance, losing health insurance by changing jobs, and difficulty in meeting medical expenses. The CPILS showed a good level of internal consistency ( = .91). The hypothesis that BMT survivors who had lower levels of physical functioning would experience more problems with living was supported by correlation (.48, p < .001) of the CPILS with the Self-Rated Karnofsky Performance Scale. The construct validity of the CPILS was further supported by a significant negative correlation (–.66, p < .002) with the scores of BMT survivors on a quality-of-life measure, the Satisfaction with Life Domains Scale for BMT.     

On the number of significant findings to be expected by chance

When multiple significance tests are computed, a certain number of significant findings will emerge simply because of chance fluctuations. In the present paper, some factors affecting the number of nominally significant results are elaborated and a general method is suggested which permits unbiased inference as to the significance of a set of findings,as a set. The method advocated employs a high speed computer to generate empirically a sampling distribution tailormade to a particular data matrix. The method is illustrated in the case of dichotomous response to inventory items, where it is found that the statistical model still often used as a basis for estimation is overly conservative. Some problems in the application of the method are discussed.This investigation, part of a larger research project, was supported primarily by research grant M-1078 from the National Institute of Mental Health of the United States Public Health Service. Gratitude is also extended to the National Science Foundation for making available research time on the IBM Model 701 computer. The present paper has benefited greatly from the comments on an earlier version offered by John Tukey and an editor ofPsychometrika.     

Sex differences in duration judgments: A meta-analytic review

We quantitatively reviewed human sex differences in the magnitude and variability of duration judgments. Data from 4,794 females and 4,688 males yielded 87 effect size estimates of magnitude and 28 of variability. The overall sex difference in duration judgment magnitude was small but statistically significant. It was moderated by whether study participants knew in advance (prospective paradigm) or only later (retrospective paradigm) that they would be required to judge duration. Although prospective judgments showed no overall sex effect, some levels of moderator variables showed a small but statistically significant effect. Retrospective judgments showed a larger subjective-to-objective duration ratio for females than for males, and several variables moderated this effect. Females' judgments also showed more intersubject variability than did males' judgments. Relative to males, females sustain attention to time more in the prospective paradigm and have better episodic memory in the retrospective paradigm.     

Counselling at a distance: Challenges and new initiatives

Traditional views of the possibilities of counselling at a distance, mediated by telecommunications technology, are challenged. The current status of telephone counselling is reviewed- it is proposed that the telephone is a vibrant innovative medium for therapeutic work. Computer involvement in therapeutic work is defined, and the issues confronting computer-mediated therapy are contrasted with developments in computer-supported co-operative work. It is concluded that active collaboration between therapists, social scientists and computer scientists is required to develop therapy-specific computer applications to mediate in therapy-at-a-distance.     

The role of ego-control, ego-resiliency, and IQ in delay of gratification in adolescence

The delay-of-gratification behavior of 104 14-year-old Ss (54 girls and 50 boys) was assessed in an experiment in which each subject chose between immediate monetary payment and larger, delayed payment on 5 occasions. Personality data were obtained on these adolescents in the form of California Adult Q-Set ratings made by several research examiners who were blind to the subjects' delay behavior. The number of delayed payments chosen was strongly correlated with these personality ratings, within both sexes. Ss who exhibited the most delay of gratification tended to be independently described as responsible, productive, ethically consistent, interested in intellectual matters, and overly controlled. They tended not to be described as unable to delay gratification, rebellious, unpredictable, self-indulgent, or hostile. Delay behavior in both sexes was also correlated positively with IQ and with Q-sort-derived indexes of ego resiliency and ego control. The relationship between ego control and delay behavior was particularly strong after both IQ and ego resiliency were partialled. These results were interpreted as reflecting the fundamental importance of both cognitive skillfulness and impulse control for adaptive delay behavior in situations that contain strong motivational inducements.     

BEHAVIORAL COMMUNITY PSYCHOLOGY: ENCOURAGING LOW-INCOME PARENTS TO SEEK DENTAL CARE FOR THEIR CHILDREN1

The present study examined the effectiveness and cost efficiency of three different techniques to encourage low-income rural parents to seek dental care for their children. The families of 51 children who needed immediate dental care (determined by dental screening at a local school) were placed into three matched groups and randomly assigned to the treatment conditions: One Prompt (Note Only), Three Prompt (Note, Telephone Contact, Home Visit), and One Prompt plus $5 Incentive. The Three Prompt and One Prompt plus $5 Incentive were significantly more effective in initiating dental visits than the Note-Only procedure. Not only was the One Prompt plus $5 Incentive technique effective in producing a slightly larger percentage of initial dental visits compared to the Three-Prompt technique, it also produced a significantly larger number of followup visits. Furthermore, the cost-effectiveness analysis showed the Incentive condition to be less costly than the Three-Prompt condition in encouraging initial dental visits.     

Modification of an impulsive cognitive tempo in emotionally disturbed boys

In order to determine the relative effectiveness of verbal self-instructions and training to delay before responding in modifying an impulsive cognitive style, 15 impulsive emotionally disturbed boys were assigned to one of three groups. The cognitive-training group was given practice in verbal self-instructions, the delay-training group received practice in delaying before responding, and the control group received no training. Posttreatment scores on the Matching Familiar Figures Test showed a significant increase in latencies for both the cognitive and delay-training groups. However, only the cognitive-training group, which had recieved practice in verbal self-instructions, made fewer errors following training. Implications for future research and potential treatment strategies for verbal self-instructions are discussed.
