Reliability of the Behavior Problem Checklist with institutionalized male delinquents

Interrater and 2-week test retest reliability coefficients were determined for subscales of the Behavior Problem Checklist on 50 males incarcerated in a state receiving facility for delinquent adolescents. Raters were 22 dormitory counselors, 2 of whom rated each child after 1 week and again after 3 weeks of observing the boys. Interrater reliability ranged from .06 to .68 on the various BPC subscales and was .50 overall, reflecting wide variation in the agreement of raters in rating boys on different dimensions. Test-retest reliability coefficients for the same rater at 2-week intervals were higher (.71 overall) and also varied among subscales. Raters were able to agree best on aggressive, acting-out behaviors. Other personality dimensions tapped by the BPC were rated with less reliability in this particular setting.This research was conducted with the cooperation and support of the Alabama Department of Youth Services, Diagnostic and Evaluation Center, Mt. Meigs, Alabama.     

Further investigation of increasing vocalizations of children with autism with a speech-generating device

We replicated and extended the findings of Gervarter et al. (2016) by using prompting and reinforcement to produce increased vocal speech with 3 young children diagnosed with autism spectrum disorder (ASD) who used a speech generating device (SGD). We extended Gervarter et al. by adopting a more robust experimental design, conducting session-by-session preference assessments, and measuring the emergence of novel vocalizations. The frequency of vocalizations increased for all 3 participants after the introduction of an echoic prompt. These results suggest that SGD-based interventions may lead to increased vocal output for children with ASD.     

The Disclosure–Intimacy Link in Computer‐Mediated Communication: An Attributional Extension of the Hyperpersonal Model

The present research investigated whether the attribution process through which people explain self‐disclosures differs in text‐based computer‐mediated interactions versus face to face, and whether differences in causal attributions account for the increased intimacy frequently observed in mediated communication. In the experiment participants were randomly assigned to a face‐to‐face or computer‐mediated interaction with a confederate who made either high‐ or low‐intimacy self‐disclosures. Results indicated that computer‐mediated interactions intensified the association between disclosure and intimacy relative to face‐to‐face interactions, and this intensification effect was fully mediated by increased interpersonal (relationship) attributions observed in the computer‐mediated condition. The article presents an attributional extension of the hyperpersonal model ( Walther, 1996 ) by demonstrating the role of causal attributions in interpersonal intensification processes in text‐based computer‐mediated interactions.     

Knowing what a novel word is not: Two-year-olds 'listen through' ambiguous adjectives in fluent speech

Three studies investigated how 24-month-olds and adults resolve temporary ambiguity in fluent speech when encountering prenominal adjectives potentially interpretable as nouns. Children were tested in a looking-while-listening procedure to monitor the time course of speech processing. In Experiment 1, the familiar and unfamiliar adjectives preceding familiar target nouns were accented or deaccented. Target word recognition was disrupted only when lexically ambiguous adjectives were accented like nouns. Experiment 2 measured the extent of interference experienced by children when interpreting prenominal words as nouns. In Experiment 3, adults used prosodic cues to identify the form class of adjective/noun homophones in string-identical sentences before the ambiguous words were fully spoken. Results show that children and adults use prosody in conjunction with lexical and distributional cues to ‘listen through’ prenominal adjectives, avoiding costly misinterpretation.     

Is there a neighborhood frequency effect in English? Evidence from reading and lexical decision

What is the effect of a word's higher frequency neighbors on its identification time? According to activation-based models of word identification (J. Grainger & A. M. Jacobs, 1996; J. L. McClelland & D. E. Rumelhart, 1981), words with higher frequency neighbors will be processed more slowly than words without higher frequency neighbors because of the lexical competition mechanism embodied in these models. Although a critical prediction of these models, this inhibitory neighborhood frequency effect has been elusive in studies that have used English stimuli. In the present experiments, the effect of higher frequency neighbors was examined in the lexical decision task and when participants were reading sentences while their eye movements were monitored. Results suggest that higher frequency neighbors have little, if any, effect on the identification of English words. The implications for activation-based models of word identification are discussed.     

Increasing social initiations in children with autism: effects of a tactile prompt

An ABAB design was used to assess the effects of a tactile prompting device (i.e., a vibrating pager) as a prompt for the social initiations of 3 children with autism during free-play activities with typically developing peers. Results indicated that the tactile prompt was effective in increasing verbal initiations for all 3 children, and responses to peers' initiations were higher for 2 participants when the tactile prompt was used. Efforts to reduce the frequency of prompts while still maintaining rates of initiations were partially successful for 1 participant.     

Data archiving for animal cognition research: report of an NIMH workshop

In July 2001, the National Institute of Mental Health sponsored a workshop titled "Data Archiving for Animal Cognition Research." Participants included scientists as well as experts in archiving, publishing, policy, and law. As is described in this report, the workshop resulted in a set of conclusions and recommendations concerning (A) the impact of data archiving on research, (B) how to incorporate data archiving into research practice, (C) contents of data archives, (D) technical and archival standards, and (E) organizational, financing, and policy issues. The animal cognition research community is encouraged to begin now to establish archives, deposit data and related materials, and make use of archived materials in new scientific projects.     

Simultaneous temporal and spatial processing

Rats searched for food that was contingent on time and place in an open field. One location was active at a time, the active location moved in a clockwise direction after each reward, and each location was repeated several times on each daily session. When a location was active, the first response after a fixed interval produced food. The intervals associated with each of the four locations were consistently 60, 30, 30 and 60 sec. For independent groups, inspecting an inactive location had no consequence (n = 7) or reduced the amount of food delivered at the active location (n = 6). The rates of inspecting active and inactive locations increased before the associated intervals elapsed, with preferential responding at the active locations. Rates of anticipation at active locations failed to superimpose when plotted as a function of proportional time. Simultaneous temporal and spatial processing contributed to the failure of proportional timing.     

Qualitative Study of Suicidality and Help-Seeking Behaviors in African American Adolescents

This qualitative study explores adolescents’ perceptions of help-seeking behaviors in the context of a hypothetical suicide crisis. Cauce and colleague’s (2002, Journal of Consulting and Clinical Psychology, 70, 44–55) model was used to examine help-seeking behaviors in 3 domains: problem recognition, decision to seek help, and selection of helpers. Forty-two church-going African American adolescents participated in 1 of 6 focus groups that discussed ways to help a hypothetically suicidal student in a vignette. Findings suggest that although the majority of youth had been exposed to a suicidal peer (76%), they were unsure of the seriousness of suicide as a problem in the African American community. The findings suggest that youth were less comfortable with formal interventions in school, religious institutions or traditional mental health settings. However, youth were open to community-based programs that could be located in school, church or community settings if helpers were: young adults, empathic listeners, non-judgmental, maintained confidentiality, and viewed as “natural helpers”. Implications for developing church-based suicide interventions are discussed. This study was supported by a K-01 Career Development Award from NIMH     

Jurors' locus of control and defendants' attractiveness in death penalty sentencing

The authors examined the relationship between jurors' locus of control and defendants' attractiveness in death penalty sentencing. Ninety-eight participants voluntarily served as mock jurors. The authors administered J. B. Rotter's (1966) Internal-External Locus of Control Scale to participants and then randomly assigned them to a group with either an attractive or an unattractive defendant (represented by photographs). Participants read a murder vignette and selected a punishment--either a lifetime jail sentence or the death penalty-for the defendant. Results indicated that neither jurors' locus of control nor defendants' attractiveness influenced sentencing. However, jurors' age and gender significantly influenced sentencing. Men, with the exception of the youngest men, were more likely than women to choose the death penalty. Additionally, young women were more likely than older women to select the death penalty. The authors discuss the implications of these results for the study of jury behavior and bias.
