DO INFANTS SHOW GENERALIZED IMITATION OF GESTURES?

Two experiments were conducted to investigate generalized imitation of manual gestures in 1- to 2-year-old infants. In Experiment 1, 6 infants were first trained four baseline matching relations (e.g., when instructed "Do this", to raise their arms after they saw the experimenter do so). Next, four novel gestures that the infants did not match in probe trials were selected as target behaviors during generalized imitation Test 1; models of these gestures were presented on unreinforced matching trials interspersed with intermittently reinforced baseline matching trials. None of the infants matched the target behaviors. To ensure that these behaviors were in the infants' motor skills repertoires, the infants were next trained to produce them, at least once, under stimulus control that did not include an antecedent model of the target behavior. In repeat generalized imitation trials (Test 2), the infants again failed to match the target behaviors. Five infants (3 from Experiment 1) participated in Experiment 2, which was identical to Experiment 1 except that, following generalized imitation Test 1, the motor-skills training was implemented to a higher criterion (21 responses per target behavior), and in a multiple-baseline, across-target-behaviors procedure. In the final generalized imitation test, 1 infant matched one, and another infant matched two target behaviors; the remaining 17 target behaviors still were not matched. The results did not provide convincing evidence of generalized imitation, even though baseline matching was well maintained and the target behaviors were in the infants' motor skills repertoires, raising the question of what are the conditions that reliably give rise to generalized imitation.     

Effects of classroom context on university students’ judgments about cheating: mediating and moderating processes

Hypothetical vignettes were used to examine the effects of classroom context variables (pedagogical quality and classroom goal structure) on undergraduate (study 1) and graduate (study 2) students’ judgments about cheating. Consistent with attribution theory and previous findings, poor (versus good) pedagogy and performance (versus mastery) goals structures resulted in more teacher blame and less student blame for cheating, and cheating was rated as more acceptable and more likely in these situations. Participants’ own prior cheating history but not their experience as a classroom teacher also affected these judgments. Relations between classroom context variables and assigned blame for cheating were mediated by students’ assessments of the fairness of the classroom situation.     

THE EFFECTS OF TEACHING PRECURRENT BEHAVIORS ON CHILDREN'S SOLUTION OF MULTIPLICATION AND DIVISION WORD PROBLEMS

We examined the effects of teaching overt precurrent behaviors on the current operant of solving multiplication and division word problems. Two students were taught four precurrent behaviors (identification of label, operation, larger numbers, and smaller numbers) in a different order, in the context of a multiple baseline design. After meeting criterion on three of the four precurrent skills, the students demonstrated the current operant of correct problem solutions. These skills generalized to novel problems. Correct current operant responses (solutions that matched answers revealed by coloring over the space with a special marker) maintained the precurrent behaviors in the absence of any other programmed reinforcement.     

THE EFFECTS OF RESPONSE CARDS ON STUDENT AND TEACHER BEHAVIOR DURING VOCABULARY INSTRUCTION

The use of response cards during whole‐class English vocabulary instruction was evaluated. Five low‐participating students were observed during hand‐raising conditions and response‐card conditions to observe the effects of response cards on student responding and test scores and teacher questions and feedback. Responding and test scores were higher for all targeted students in the response‐card condition. The teacher asked a similar number of questions in both conditions; however, she provided more feedback in the response‐card condition.     

Stressed out over possible failure: The role of regulatory fit on claimed self-handicapping

The self-protective mechanism of self-handicapping appears to be motivated by the need to protect ability attributions in the face of concern about possible failure. Indeed, the present research finds a correlation between trait self-handicapping and chronic prevention focus. Moreover, the present research examines the role of “regulatory fit” on the use of claimed self-handicapping by exposing high and low trait self-handicappers to performance situations framed in prevention or promotion terms. Consistent with our regulatory fit hypothesis, high self-handicappers (HSHs) handicapped significantly more (by reporting higher levels of stress) when the task was framed in prevention focus rather than promotion focus terms, and did so even when the viability of the handicap was dubious. Self-handicapping in the prevention focus condition was mediated by elevated feelings of evaluative concern. The findings suggest that conditions of regulatory fit (i.e., HSHs under prevention focus) can lead to increased use of self-handicapping.     

Right frontal EEG asymmetry and behavioral inhibition in infants of depressed mothers

Recent studies have shown associations between maternal psychopathology and inhibited behaviors in infants. Moreover, physiological factors have been identified as affecting the continuity of behavioral inhibition across childhood. The purpose of the present study was to examine electroencephalogram (EEG) activity and inhibited behavior in 12-month-old infants of depressed versus non-depressed and mothers. Repeated measures MANOVAs indicated that the infants of mothers with stable psychopathology had greater relative right frontal EEG asymmetry, a pattern that typically accompanies greater negative affect and greater withdrawal behaviors. Infants of affectively ill mothers also showed more proximal behaviors toward a stranger and a novel toy than infants of well mothers, but fewer non-proximal behaviors toward their mothers. These results are discussed within a framework of behavioral inhibition for infants exposed to early psychopathologies in their mothers.     

Depressive Symptoms in Young Adults: The Role of Attachment Orientations and Romantic Relationship Conflict

Although romantic involvement in adulthood has generally been associated with enhanced well-being, some aspects of adults’ romantic relationships (e.g., maladaptive conflict behaviors) have been linked with depressive symptoms. In order to better understand the role of romantic involvement in well-being, the present study examined links among attachment orientations, conflict behaviors with romantic partners, and depressive symptoms in an undergraduate sample of young adults (N = 110). Correlational analyses generally supported the hypothesized links. When a regression series was applied to the data in order to determine whether young adults’ conflict behaviors serve as a mediator in the link between their attachment orientations and depressive symptoms, mediation was not supported. Instead, results supported a model wherein attachment orientations and conflict behaviors (attacking) were independent predictors, explaining unique variance in young adults’ depressive symptoms. Findings underscore the importance of considering specific aspects of young adults’ romantic relationships in the prediction of their depressive symptoms and illuminate the role attachment orientations and conflict behaviors in their depressive symptoms.     

The relationship between violence and youth suicide indicators among Asian American and Pacific Islander youth

The literature documents a relationship between interpersonal violence and suicide. One tool used to understand interpersonal violence is the Power Wheel, developed from clinical experience and originally used in domestic violence education. We examine the relationship between Teen Power and Control Wheel domains and suicidal indicators (seriously considered suicide, made a suicide plan, and attempted suicide) among Asian American and Pacific Islander high school students, in terms of both victimization and perpetration. Data from a 2007 survey of two multi-ethnic high schools on the island of O'ahu, Hawai'i were used. The survey assessed interpersonal youth violence and a multitude of risk and protective factors. It found that females were significantly more likely to seriously consider suicide and attempt suicide, compared to males. There were no statistically significant differences in seriously considering suicide, making a suicide plan, and attempting suicide by ethnic group, employment status, or hours worked per week. Using the Wheel, we found that all dimensions for victimization and perpetration were associated with the three suicidal indicators. However, the magnitude of this association was dramatically higher for victims than for perpetrators. School- and healthcare-based prevention strategies should ensure that both suicide and violence intervention components are addressed. Professionals who work with youth should be trained to feel comfortable, confident, and competent in discussing suicide and violence, and be willing and capable to assess and intervene.
