Memory and Affect: Autobiographical Memory Distribution and Availability in Normal Adults and Recently Detoxifed Alcoholics

An autobiographical memory task was administered to a group of 15 male alcoholics (duration of abuse x = 16 years) and to a control group comprised of 15 nonabusers. The alcoholics were inpatients in a chemical dependence treatment program who had their last drink 8 days prior to testing. Two aspects of autobiographical memory were compared. First, the distribution of memories for life events over the lifespan clearly differed for the two groups. The alcoholic group recalled far fewer memories from the most recent 5 years and showed an exaggerated tendency to recall memories from their early adulthood when compared to the control group. This result is consistent with a model of the onset of a temporally graded retrograde amnesia subsequent to a protracted period of alcohol abuse. In such cases the context for self-evaluation may remain heavily rooted in late adolescence. Second, in contrast to results of the control group, the data from men in the alcohol group revealed no relationship between latency to report autobiographical memories associated with a particular affect and self-rated frequency of such affects. This dissociation indicates the possible impact of atypical memory performance on views of the self.     

The EARLY ALLIANCE Prevention Trial: An Integrated Set of Interventions to Promote Competence and Reduce Risk for Conduct Disorder, Substance Abuse, and School Failure

Describes the EARLY ALLIANCE interventions, an integrated set of four programs designed to promote competence and reduce risk for early-onset conduct disorder, substance abuse, and school failure. These interventions are evaluated as part of a prevention trial that begins at school entry and targets child functioning and socializing practices across multiple contexts (school, peer group, family) and multiple domains (affective, social, and achievement coping-competence). The paper presents the conceptual foundation of the four interventions, including a synopsis of the risk and protective factors associated with conduct disorder and related outcomes, and of the coping-competence model driving EARLY ALLIANCE. The developmental rationale, intended impact, and procedures are described for each intervention: a universally administered classroom program and indicated, peer, reading-mentoring, and family programs. Interventions are currently being tested in a prevention trial, which is briefly summarized.     

An evaluation of the short-term impact of a media-based substance abuse prevention programme

A state-wide substance abuse prevention programme, entitled KidsInTouch, incorporated a multifaceted approach involving: (a) media-based interventions; and (b) parent training workshops. KidsInTouch was targeted at parents and their children, ages five to 12 years. The media-based interventions attempted to increase children's and parents' awareness and knowledge about substance abuse and prevention. In addition, the intervention advertised and solicited audience participation in parent training workshops. Parents participating in the parent training workshops, in comparison to the control parents, evidenced significant improvement in both alcohol and other drug knowledge and parenting skills. The implications of using the media and involving children and their parents in substance abuse prevention programmes are discussed.     

Impact of substance abuse and child maltreatment training on service utilization in a rural setting

Substance abuse and child maltreatment have been recognized as co-morbid problems encountered in families presenting in the child protective services (CPS) system. Nonetheless, utilization rates of substance abuse treatment services have generally lagged well behind what the research would suggest are prevalence rates for substance abuse disorders in this population, suggesting problems in recognition and referral practices among CPS workers. In response to this, 25 training programs were funded by the National Center on Child Abuse and Neglect. This study reports data from one program. Trainees indicated a high level of satisfaction and demonstrated significant knowledge gains. More importantly, utilization of substance abuse services increased significantly across time in a multi-county region receiving training relative to a comparison region receiving none. The gain was limited, suggesting that while increased knowledge may translate into increased service utilization, additional barriers to accessing needed services must also be addressed.     

TEACHING NAMING OF COIN VALUES—COMPREHENSION BEFORE PRODUCTION VERSUS PRODUCTION ALONE1

The purposes of this experiment were to determine whether (a) it would require fewer trials to teach verbal production of coin values directly or to teach auditory comprehension first, (b) comprehension training would generalize or transfer to production, and (c) production training would generalize to comprehension. Fourteen mentally retarded subjects participated. Their mean mental age was 4.83 yr (SD = 1.83), their mean chronological age was 12.67 yr (SD = 3.17), their mean IQ was 43.86 (SD = 7.81), and their mean arithmetic grade level was Kindergarten 0.1. A matched groups pretest-posttest design, as well as a multiple baseline across responses within each group were employed. The Comprehension-Production Group received coin-value training using two procedures sequentially: auditory comprehension (pointing to the correct coins in response to their verbally stated value) followed by verbal production (verbally stating the coins' value in response to a pointing prompt). The Production Group was trained on the production procedure only. Each subject was repeatedly administered coin-value comprehension and coin-value production tests, which provided the dependent measures. The results indicated that the two experimental groups improved significantly in their comprehension and production of coin values from pretest to posttest and maintained those increments on one- and four-week followup tests. Mean group performance on four-week followups ranged from 89 to 96% correct for the two dependent measures and two groups. Multiple-baseline data showed pronounced increases in performance only after training was initiated on a particular coin. A comparison of the number of trials required for both groups to complete their respective training programs indicated that teaching production alone (X? trials = 137.42) was significantly more efficient than training both comprehension and production (X? = 281.71). The failure of the comprehension procedure to facilitate production acquisition was evidenced by the fact that the Comprehension-Production Group required as many verbal naming trials to achieve mastery as did the Production Group. On the other hand, there was generalization from production training to comprehension. Subjects in the Production Group who were not trained to point to the coins in response to verbal instruction averaged 99% correct on the comprehension test. Research to this point may suggest an interaction between mental level and direction of transfer. The mentally retarded may experience facilitation from production to comprehension training, and for the nonretarded, the direction of transfer may be the converse.     

Correspondence training, prior verbal training, and control of nonverbal behavior via control of verbal behavior

The role of prior verbal training in correspondence training and later verbal control of nonverbal behavior was examined in two groups of Head Start children. One group received correspondence training without prior verbal training, the other with. Essentially no differences were found between the two sequences; thus it seems appropriate to consider the content phases (reinforcement contingent on target verbalization alone) of previous research as control procedures and not a necessary precursor to correspondence training.     

OVERCORRECTION: GENERALIZATION AND MAINTENANCE1

The present study examined the effects of one component of overcorrection—verbal reprimands—and compared them with the effects of the entire overcorrection procedure. Generalization and maintenance of effects were also evaluated. A combined reversal and multiple-baseline experimental design was used to evaluate the effect of the various contingencies on the inappropriate searching behavior of a severely and profoundly mentally retarded adult living in a group home. Searching was defined as carefully and thoroughly touching floors, sofas, cabinets, etc. Data were collected by group-home personnel during three separate observation periods each day of the 115-day study: before breakfast, after breakfast, and after dinner. Observers also served as experimenters. Following an initial baseline phase, verbal reprimands followed searching behavior during two daily experimental periods in multiple-baseline fashion. An immediate reduction of searching during experimental periods occurred with the onset of verbal reprimands. No reduction was observed in the third daily observation period, the control session. After a second baseline phase, during which searching behavior was not shown to return to the original baseline levels, overcorrection procedures (washing hands) were instituted. Overcorrection virtually eliminated inappropriate searching during both daily experimental periods. Further, the effects generalized to the daily control session. In a final experimental phase, decreased searching behavior was maintained with verbal reprimands alone.     

AN INVESTIGATION OF THE EFFECTS OF TOKEN REINFORCEMENT ON DIVERGENT VERBAL RESPONDING1

The effect of token reinforcement on three classes of divergent verbal responding to verbal stimulus items from three measures of the Wallach-Kogan Creativity test was examined. The subjects consisted of two “gifted”, two “average”, and two “learning disabled” children from a public-school setting. The design utilized both an intra-subject and inter-subject multiple-baseline design with a reversal design added. Tokens were dispensed contingent upon the number of appropriate verbal responses to each stimulus item, i.e., a continuous schedule of reinforcement was used—one token per appropriate response. Interobserver agreement on “appropiateness” was 993%. The tokens could be used to “purchase” items listed in a “menu” format (e.g., ball and jacks—100 tokens). Consistently large effects of token reinforcement were observed, without generalization of effect across the three classes of behaviors, or conditions. These results support the works of Goetz and Baer (Journal of Applied Behavior Analysis, 1973, 6 , 209–217), Goetz and Salmonson (Behavior Analysis and Education, G. Semb, (Ed.), University of Kansas, 1972, 53–61), and Maloney and Hopkins (Journal of Applied Behavior Analysis, 1973, 6 , 425–434). Implications lie in continued experimental analysis of behavior approach to the concept called “creativity”. Additionally, implications are made in classroom application of assessing and intervening in the area of divergent responding for children with deficits in those areas.     

Incidental teaching of language in the preschool

"Incidental teaching" denotes a process whereby language skills of labelling and describing are learned in naturally occurring adult-child interactions. In the present study, 15-min daily samples of the spontaneous speech of 11 children were recorded during free play over eight months of preschool. After incidental teaching of compound sentences, increases in unprompted use of compound sentences were seen for all the children, first directed to teachers, and then to children, in accordance with who attended to the children's requests for play materials. The incidental teaching procedure also stimulated spontaneous variety in speech, and appears to have general applicability to child learning settings.     

The role of verbal behavior in human learning: II. Developmental differences

When children in four different age ranges operated a response device, reinforcers were presented according to fixed-interval schedules ranging in value from 10 to 70 seconds. Only the behavior of the subjects in the youngest of the four groups, the preverbal infants, resembled that of other animal species. The children in age ranges 5 to 6½ and 7½ to 9 years exhibited either the low-rate or high-rate response patterns typical of human adults. Those who showed the low-rate pattern reported a time-based formulation of the contingencies and some of them were observed to occasionally count out the interval before responding. The performance of children aged 2½ to 4 years differed from that of both infants and older children, though containing some patterning elements similar to those produced by the older and younger subjects. The predominant response pattern of the infants consisted of a pause after reinforcement followed by an accelerated rate of responding that terminated when the next reinforcer was delivered. Analysis of postreinforcement-pause duration and response rate showed that infant performance, but not that of the older children, consistently exhibited the same kinds of schedule sensitivity observed in animal behavior. The evidence supports the suggestion that the development of verbal behavior greatly alters human operant performance and may account for many of the differences found between human and animal learning.
