Correlates of sociometric status in school children in Buenos Aires

Teacher ratings on Spanish translations of the Comprehensive Behavior Rating Scale for Children and peer nominations were obtained for 110 school children (42 boys and 68 girls) in grades 2– 5 at a public elementary school in Buenos Aires. Nominations of likes best were negatively correlated with language processing deficits, attention problems, and sluggish tempo as rated by both teachers and peers, and positively correlated with teacher ratings of social competence, for both boys and girls. The reverse pattern was found for nominations of likes least. Children were assigned to sociometric status groups of popular (n=27), rejected (n=28), neglected (n=7) controversial (n=11), and average (n=37) based on number of LL and LB nominations. Rejected and popular children could be differentiated by teacher and peer ratings of linguistic information processing deficits, inattention, and sluggish tempo. Behavioral characteristics of motor hyperactivity, impulsivity, and aggression were significantly associated with being male but did not differ by sociometric status group.The assistance of Claudia Colon, Educational District of Buenos Aires, and Viviana Smith, Department of the Interior, Argentina, in the translation of measures is gratefully acknowledged.

Locus of semantic priming effects in speeded naming

The locus of semantic priming effects was examined by measuring onset and rime durations as well as response latencies of words with consistent and inconsistent pronunciations, using the postvocalic naming task. We found that the effect of a semantic prime on naming duration was localized rather than spread across the entire word; onset durations were shorter in the related condition than in the unrelated condition, but rime durations were equal in the two prime conditions. Moreover, the priming effect on onset durations was larger for words with inconsistent than for those with consistent pronunciations. These duration results cannot be accounted for by previous proposals, but they can be accounted for by models in which phonemes are activated in parallel rather than serially from left to right and in which motor programs are based on phonemes rather than syllables. Contrary to previous reports of an interaction of prime and regularity (a factor closely related to consistency) on naming latency, we found no interaction of prime and consistency on response latency. We argue that this conflict is only apparent and arises because naming latency conflates response latency and initial phoneme duration for some targets.     

Gender Differences in the Suicide-Related Behaviors of Adolescents and Young Adults

Gender differences in suicide-related behaviorswere examined in an older adolescent and a young adultsample (primarily Caucasian). Suicide-related behaviorswere assessed by the Life Attitudes Schedule (LAS) as well as by measures of depressivesymptomatology and hopelessness. The LAS measures a broadcontinuum of potentially life-diminishing orlife-enhancing behaviors. There are four LAScontent-category subscales: overtly suicidal and death-related,self-related, risk and injury-related, and health-relatedbehaviors. As hypothesized, in both samples, genderdifferences in the expression of suicide-related behaviors were obtained. Males from both samplesendorsed substantially more risk-taking andinjury-producing behaviors than females. Males in bothsamples also reported more negative health-relatedbehaviors than females. In contrast, females reported moresymptoms of depression than males. Hopelessness scoresonly differentiated male and female young adults; maleand female adolescents did not differ significantly on the hopelessness measure. These findings areprimarily discussed in terms of gender-role socializationtheory. Implications for the treatment of suicidality aredrawn.     

Category and Attribute Knowledge Deterioration in Alzheimer's Disease

A prevalent theory regarding the deterioration of semantic memory in Alzheimer's disease is that it is a bottom-up process. If this is true, performance on tests of attribute knowledge should decline more rapidly than performance on tests of categorical knowledge as dementia severity increases. In the present study, a convincing pattern of findings to either support or reject the theory failed to emerge. This raised questions regarding the ability to separate attribute and categorical knowledge, and whether one can be tested without influence of the other. Questions also were raised regarding the additional cognitive processes needed to complete tasks of semantic memory.     

The influence of prosodic structure on the resolution of temporary syntactic closure ambiguities

This paper investigates the influence of prosodic structure on the process of sentence comprehension, with a specific focus on the relative contributions of syntactic and prosodic information to the resolution of temporary syntactic closure ambiguities. We argue that prosodic structure provides an initial memory representation for spoken sentences, and that information from this prosodic representation is available to inform syntactic parsing decisions. This view makes three predictions for the processing of temporary syntactic ambiguity: 1. When prosodic and syntactic boundaries coincide, syntactic processing should be facilitated. 2. When prosodic boundaries are placed at misleading points in syntactic structure, syntactic processing should show interference effects. 3. The processing difficulties that have been reliably demonstrated in reading experiments for syntactically complex sentences should disappear when those sentences are presented with a felicitous prosodic structure in listening experiments. These predictions were confirmed by series of experiments measuring end-of-sentence comprehension time and cross-modal naming time for sentences with temporary syntactic closure ambiguities. Sentences with coinciding or conflicting prosodic and syntactic boundaries were compared to a prosodic baseline condition.This research was supported in part by NIMH grant R29 MH51768 to the first author and NIMH grant T32 MH19729 to the Northeastern University Psychology Department.     

An experimental demonstration of discriminated (nongeneralized) imitation

In a number of experiments, nonreinforced imitation has been found to persist at high rates despite the variety of procedures which have been employed to eliminate such responses. In the present experiment, powerful stimulus control was established over imitation by providing an alternative response which was reinforcible. Four children participated in a multiple-schedule experiment in which imitation was reinforced in the presence of one light and bar pressing in the presence of a second light; throughout the experiment, responses were modeled on each trial: hand-arm responses in the presence of the red light and leg responses in the presence of the yellow light. Initially, imitation was reinforced in the presence of the red light and button pressing in the presence of the yellow light. In a within-subjects design, stimulus control was demonstrated by reversing the association of lights and contingencies, then reinstating the original contingencies. The children imitated when reinforced for imitation and pressed the button when button pressing was reinforced. The results demonstrate stimulus control over imitation which is more powerful than in previous investigations and indicate that the prevailing reinforcement contingencies determine whether or not a child will imitate on a particular occasion.This research was supported by a Faculty Summer Research Grant from The American University.

Motivation to manage among college business students: A reassessment

The present study reassesses trends in motivation to manage among college business students (N = 216). Motivation to manage scores are compared with J. B. Miner's (Personnel Psychology, 1974, 27, 605–613) results for three periods since the early 1960s, across two types of universities—public and private, and between males and females. Results indicate that the downward trend in motivation to manage scores appears to be reversing; business students at the private university scored higher on motivation to manage than those at the public university, and males scored higher than females. Implications for vocational research are discussed.     

AN EVALUATION OF TEACHING-FAMILY (ACHIEVEMENT PLACE) GROUP HOMES FOR JUVENILE OFFENDERS

Juvenile crime is a serious problem for which no treatment approach has been found to be reliably effective. This outcome evaluation assessed during and posttreatment effectiveness of Teaching-Family group home treatment programs for juvenile offenders. The evaluation included the original Achievement Place program, which was the prototype for the development of the Teaching-Family treatment approach, 12 replications of Achievement Place, and 9 comparison group home programs. Primary dependent measures were retrieved from court and police files and included number of alleged offenses, percentage of youths involved in those alleged offenses, and percentage of youths institutionalized. Other dependent measures were subjective ratings of effectiveness obtained from the program consumers, including the group home residents. The results showed difference during treatment favoring the Teaching-Family programs on rate of alleged criminal offenses, percentage of youths involved in those offenses, and consumer ratings of the programs. The consumer ratings provided by the youths and their school teachers were found to be inversely and significantly correlated with the reduction of criminal offenses during treatment. There were no significant differences during treatment on measures of noncriminal offenses (e.g., truancy, runaway, and curfew violations). In the posttreatment year, none of the differences between the groups was significant on any of the outcome measures. The results are discussed in terms of measurement and design issues in the evaluation of delinquency treatment programs and in relation to the evaluation of Teaching-Family group homes by Richard Jones and his colleagues.
