Successful intervention with multi-problem mothers: Effects on the mother-infant relationship

A two-step model of intervention for multi-problem mothers was proposed. In order to improve mother-child interaction and later developmental outcomes, the first step is for the practitioner to help the mother change her external competencies (adult social skills) and internal perceptions (support, depression). These changes make the second step possible—the mother then can learn to foster her own child's development. The model was tested in a study of 95 multi-problem women who participated in a nursing intervention program from mid-pregnancy through the child's first birthday. The results supported the two-step model. Improvements in the mothers' external competencies were related to completion of intervention goals. These external improvements also were related to more optimal patterns of mother-child interaction during teaching and feeding episodes at 1 year. Furthermore, an especially insecure type of attachment relationship was found more frequently among the infants of mothers in the group that did not improve. Changes in internal perceptions were unrelated to intervention or interaction measures. These unexpected results suggest that the mother's internal improvements may have a more delayed or a less direct effect upon the child.     

Infant-mother attachment and children's friendship quality: maternal mental-state talk as an intervening mechanism

Utilizing data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development, we investigated mothers' talk about mental states during play with their 24-month-old children as a mechanism though which infant-mother attachment was associated with children's later friendship quality. A series of repeated measures analyses of covariance indicated that a secure versus avoidant or disorganized infant-mother attachment was associated with more maternal talk about cognitions (but not emotions or desires) at 24 months. Latent growth curve models tested within a structural equation modeling framework revealed indirect effects of infant-mother attachment on observed and mother-reported positive friendship interaction at 54 months and decreases in mother-reported negative friendship interaction from 54 months to 1st grade via maternal cognitive talk at 24 months.     

Paradoxical effects of education on the Iowa Gambling Task

Suitable normative information on the Iowa Gambling Task (IGT) is not currently available, though it is clear that there is great individual variability in performance on this assessment tool. Given that the task is presumed to measure the emotion-based learning systems that are thought to form the biological basis of 'intuition,' there is some reason to think that education (especially tertiary education) might explicitly de-emphasise the role of emotion-based learning in decision-making. This suggests the paradoxical finding that better-educated participants should show poorer performance on the IGT. We recruited 30 participants (all female, all aged 18-25) to participate in a 'real money' version of the IGT. There was no significant difference in performance in blocks 1-3 of the task (trials 1-60). However, there was a substantial effect of education on the final two blocks (trials 61-100), such that the less-well-educated participants produced twice as much of an improvement over baseline as did their university-educated colleagues. A range of possible explanations for this remarkable finding are discussed. The most likely appears to be that tertiary education specifically discourages the use of emotion-based learning systems in decision-making. These findings bear on the extent to which education has a role to play in our reliance on cognition and emotion in decision-making, including the likely role of education in the generation and maintenance of false beliefs.     

A positive emotional bias in confabulatory false beliefs about place

Some neurological patients with medial frontal lesions exhibit striking confabulations. Most accounts of the cause of confabulations are cognitive, though the literature has produced anecdotal suggestions that confabulations may not be emotionally neutral, having a ('wish-fulfilment') bias that shapes the patient's perception of reality in a more affectively positive direction. The present study reviewed every case (N = 16) of false beliefs about place reported in the neuroscientific literature from 1980 to 2000, with blind raters evaluating the 'pleasantness' of the patient's actual and confabulated locations. In each case the confabulated location was evaluated as more pleasant. This striking finding supports the claim that there may be a systematic affective bias in the false beliefs held by neurological patients with confabulation.     

The influence of activity choice on problem behaviors maintained by escape versus attention

This study assessed whether the function of an individual's problem behavior was related to the effectiveness of an intervention involving choice among tasks. Analogue functional analyses were conducted with 7 students with various diagnoses to determine whether problem behaviors were maintained by escape or attention. Following identification of the function of each student's problem behavior, reversal designs were used to assess the effectiveness of an intervention that allowed the students to choose their own instructional tasks. Results showed that students who displayed escape-maintained problem behavior showed substantial reductions in such behavior when they were provided with opportunities to choose among tasks. On the other hand, students who displayed attention-maintained problem behavior did not show any effects as a result of the choice intervention. These findings are discussed in terms of the effective use of behavior management programs involving choice and the reduction of problem behavior.     

Gender Differences in Patterns of Association Between Prosocial Behavior, Personality, and Externalizing Problems

This study examines whether prosocial behavior and personality have independent or overlapping associations with adolescent externalizing problems. A total of 128 female and 103 male early adolescents (M = 13.6 years old) completed personality inventories. Prosocial behavior was assessed by peer nominations (N = 663). Composite aggression and delinquency scores were derived from maternal and self-reports. Path analyses indicated gender differences in patterns of association. For girls, links between prosocial behavior and both aggression and delinquency were fully mediated by agreeableness and partially mediated by conscientiousness. For boys, prosocial behavior, agreeableness, and conscientiousness were independently and negatively associated with aggression and delinquency. The findings suggest that personality and prosocial behavior are uniquely related to boys' behavior problems but cannot be readily disentangled when it comes to girls' behavior problems.     

Maternal depression and locus of control orientation as predictors of dyadic play behavior

Maternal locus of control orientation and depression were examined in relation to joint negotiation and coordination of mother-child play at 20 months. Subjects were 51 high-social-risk mothers and children. Mothers completed the I-E Scale and the Beck Depression Inventory prenatally and at 20 months; mother-child interaction was videotaped in a laboratory playroom at 20 months. Tapes were coded using the Control-Autonomy Balance Scales to evaluate maternal control and sensitivity and child engagement and autonomy. Analyses of dyadic play behavior indicated that maternal controllingness was related to an external locus of control orientation. Child engagement during play was related to the resolution of mild maternal depression.     

Attachment, Friendship, and Psychosocial Functioning in Early Adolescence

Fifth-graders' (N = 162; 93 girls) relationships with parents and friends were examined with respect to their main and interactive effects on psychosocial functioning. Participants reported on parental support, the quality of their best friendships, self-worth, and perceptions of social competence. Peers reported on aggression, shyness and withdrawal, and rejection and victimization. Mothers reported on psychological adjustment. Perceived parental support and friendship quality predicted higher global self-worth and social competence and less internalizing problems. Perceived parental support predicted fewer externalizing problems, and paternal (not maternal) support predicted lower rejection and victimization. Friendship quality predicted lower rejection and victimization for only girls. Having a supportive mother protected boys from the effects of low-quality friendships on their perceived social competence. High friendship quality buffered the effects of low maternal support on girls' internalizing difficulties.     

The influence of upcoming food-pellet delivery on subjects' responding for 1% sucrose reinforcement delivered by concurrent random-interval schedules

Researchers have demonstrated that rats' rates of operant responding that are maintained by 1% liquid-sucrose reinforcement will increase if food-pellet reinforcement is upcoming within the same session. The authors investigated whether a similar induction effect would be observed when rats pressed a lever for 1% sucrose that was delivered by concurrent random-interval schedules of reinforcement. Results demonstrated that upcoming noncontingent food-pellet delivery increased absolute response rates on the concurrent schedules in 10 of 12 possible instances. Upcoming food-pellet delivery also increased subjects' sensitivity to reinforcement on the concurrent schedules, as measured by the generalized matching law (W. M. Baum, 1974), in 5 of 6 possible instances. The present results extended the finding of induction to responding on concurrent schedules. They also added to evidence suggesting that the effect occurs because the reinforcing value of the weak reinforcer (i.e., the 1% sucrose) has been increased.     

Induction when rats lick for 1% liquid-sucrose reinforcement

Previous research reported that rats responding for 1% liquid-sucrose reinforcement when 32% sucrose reinforcement is upcoming will decrease their response rate (contrast) if licking is the dependent measure and increase their response rate (induction) if pressing a lever is the dependent measure. The present study investigated whether induction could be observed when licking served as the dependent measure and whether induction in lever pressing and contrast in licking behaviour could be concurrently observed. Experiment 1 found induction when rats licked to earn the rewards but consumed them at a location separate from the spout licked to earn them. Experiment 2 also found induction when rats earned (and consumed) rewards by licking the same spout throughout the session. Experiment 3 separately measured instrumental lever pressing for sucrose rewards and licking the sucrose during the reward period. We found that both measures increased for 1% sucrose when 32% sucrose reinforcement was upcoming. The present results indicate that the type of response is not the sole determinant of whether contrast or induction is observed. Rather, they suggest that other procedural details, such as the location of reinforcer delivery, influence which effect is observed. The results also indicate that associative processes underlie the appearance of induction in responding for 1% sucrose.
