Early intervention in the family system: A framework and review

A framework for understanding the effect of early intervention on family structure and functioning is presented. The framework uses five sets of variables to characterize families: Their ecology; and the values, roles, personalities, and interactions of family members. Twenty research studies that met criteria of having comparison/control groups, beginning intervention either prenatally or during the first 3 months of infancy, and directing intervention to family functioning are abstracted and examined in detail. Successful and unsuccessful studies are compared as to population and nature of intervention. Two criteria of success are used: (1) The commonly used criterion of any positive change; (2) a more rigorous criterion of change in at least three areas of family functioning, based on the assumption that more pervasive change will have more lasting influence on child development. Application of the first criterion found that 75% of early family focused intervention studies showed a successful outcome. Application of the latter criterion found that 50% showed a successful outcome. Further, there were no significant differences between successful and unsuccessful studies as to target group or type of intervention. The review suggests that early intervention targeted at family functioning is effective and that a more pervasive and sustained effect is likely if the intervention includes at least 11 or more contacts over at least a 3-month period.     

Twelve‐Step Groups,Attributions of Blame for Personal Sadness,Psychological Well‐Being,and the Moderating Role of Gender1

Two studies investigated links among 12‐step group participation, gender, attributions of blame for personal sadness, and psychological well‐being. Study I used a correlational design to examine these links cross‐sectionally among substance abusers who identified alcohol as their primary drug problem. Study 2 used an experimental design to examine prospective links among these variables for substance abusers who were also adult children of alcoholics. Females engaged in more blame than did males, and personal blame was negatively related to psychological well‐being in Studies 1 and 2. Most significantly, 12‐step group participation was associated with lower personal blame among females but not among males across both studies. These results indicate that 12‐step groups can reduce personal blame among females who have substance abuse problems.     

Strategy selection in causal reasoning: when beliefs and covariation collide.

The present study investigated how people combine covariation information (Cheng & Novick, 1990, 1992) with pre-existing beliefs (White, 1989) when evaluating causal hypotheses. Three experiments, using both within- and between-subjects designs, found that the use of covariation information and beliefs interacted, such that the effects of covariation were larger when people assessed hypotheses about believable than about unbelievable causal candidates. In Experiment 2, this interaction was observed when participants made judgments in stages (e.g., first evaluating covariation information about a causal candidate and then evaluating the believability of a candidate), as well as when the information was presented simultaneously. Experiment 3 demonstrated that this pattern was also reflected in participants' metacognitive judgments: Participants indicated that they weighed covariation information more heavily for believable than unbelievable candidates. Finally, Experiments 1 and 2 demonstrated the presence of individual differences in the use of covariation- and belief-based cues. That is, individuals who tended to base their causality judgments primarily on belief were less likely to make use of covariation information and vice versa. The findings were most consistent with White's (1989) causal power theory, which suggests that covariation information is more likely to be considered relevant to believable than unbelievable causes.     

Differences in performance on a reversal learning test and division of labor in honey bee colonies

We studied the association between honey bee (Apis mellifera) division of labor and performance on an olfactory reversal-learning test. Manipulations of colony age structure and flight experience were used to test whether differences in performance are associated with age, current behavioral state, or flight experience. Nurse bees showed significantly faster rates of extinction to a learned odor than did foragers. This difference was associated primarily with differences in behavioral state, rather than age; it was seen when comparing nurses and foragers from typical colonies and normal-age nurses and precocious foragers from single-cohort colonies. Differences in extinction rate were not related to differences in flight experience; there was no difference between foragers and foraging-age bees denied flight experience. These results suggest that changes in learning and memory occur in association with division of labor. We speculate on the possible functional significance of the difference in extinction rate between nurses and foragers. Received: 15 January 2000 / Accepted: 22 August 2000     

Father-infant interaction program: Preparation for parenthood

The role of the father in child care has been expanding in recent years. Today, the father assumes a more active interest in his wife's pregnancy and participates more in the care and nurturing of his children. Fathers are most comfortable and confident when they have direct exposure and experience with their infants from the time of the infants' birth. To be of greater assistance, preparation for parenthood courses can increase the information that they offer on the father's role with his children. These courses can provide opportunities for expectant fathers to meet separately from their wives to discuss and share concerns and feelings about parenthood. Fathers express very positive feelings about having opportunities to interact with their infants and to discuss concerns and feelings with other fathers.     

Negotiation Teamwork: The Impact of Information Distribution and Accountability on Performance Depends on the Relationship among Team Members

We examined how the distribution of information among team members and accountability pressures affected the quality of negotiated settlements reached among teams of friends negotiating against teams of strangers. The main conclusions of the experiment may be summarized by the following findings: (1) Teams of strangers reaped a greater share of the joint profit than did teams of friends when teammates were accountable to a supervisor as opposed to negotiating strictly on their own behalf. (2) Teams of strangers also reaped a marginally greater share of the joint profit than did teams of friends when teammates possessed unique, as opposed to common, information about their own team's preferences. (3) Not surprisingly, teams of friends were more cohesive than were teams of strangers; however, teams of friends were also more concerned about maintaining their relationship than were teams of strangers. (4) Teams of friends felt least cohesive when they were accountable to a supervisor, whereas teams of strangers felt most cohesive when they were accountable. Similarly, friends indicated greater relationship concerns when having to deal with distributed information, whereas information distribution had no effect on the relationship concerns of strangers. (5) For teams of strangers, greater team cohesiveness was positively correlated with better performance. (6) Moreover, when teams of strangers felt more cohesive than their opponents, they earned more than teams of strangers who felt less cohesive.     

Immigrant youth of Indian origin: Generational differences in self-critical perfectionism

A community sample of foreign-born first generation (n = 53) and U.S.-born secondgeneration (n = 57) youth of Indian origin (ages 18–25) was studied. Variables predicting self-critical perfectionism were perceived prejudice, enculturation, and communication difficulty with parents and their interaction with generation status. The differences between the two generations pointed to nuanced self-pressures of Indian immigrant youth, despite good academic standing and middle-class family income. Implications discuss counseling with Indian immigrant youth.     

Canine responses to familiar and unfamiliar humans

Dogs were observed during controlled approaches by their owners and by strangers. Significant differences between the dogs' responses to their owners and their responses to strangers were found. These results supported the popular belief that dogs respond differently to different persons, and not merely to different situations in which persons are usually encountered.
