EFFECT OF CUEING ON SELF-CONTROL OF CLASSROOM BEHAVIOR

Behavioral self-control procedures, composed of self-assessment, self-recording, self-determination and administration of reinforcement, were introduced into a regular third-grade classroom immediately after a baseline period. The procedures produced a small and unstable increase in the level of on-task behavior in eight of the nine subjects. After a second baseline period, a cueing procedure was introduced, using a chart specifying on-task behavior. This enabled within-lesson changes in on-task behavior to be posted clearly for the children. The cueing procedure combined with the self-control procedures produced a high and stable increase in on-task behavior in all subjects.     

Classroom applications of self-determined reinforcement

Self-determined, experimenter-determined, and chance-determined token reinforcement treatments were compared with a no-token treatment, in terms of effect on the learning of history and geography material in the classroom. Each treatment was assigned to one of four heterogeneous classes of Grade nine girls. An initial baseline period preceded the differential reinforcement period, and a token withdrawal period followed. Subsequently, the self-determined treatment was employed in all three token reinforcement classes, before a final baseline period occurred. Findings included a similarity of initial baseline performance for all classes, an equal superiority of self-determined and experimenter-determined treatments to chance-determined and no-token treatments, and significant improvement from initial baseline to final baseline for self-determined and experimenter-determined treatments, but not chance-determined and no-token treatments. Differential token reinforcement experience was found to influence subsequent rate of self-determined token reinforcement.     

Oculomotor adjustments in darkness and the specific distance tendency

Two experiments were performed to investigate the relationship between the oculomotor adjustments assumed in total darkness and perceived distance under reduced visual conditions. Experiment I compared the dark focus of accommodation with the perceived distance of a monocular light point presented in a dark environment. Experiment II compared the convergence angle assumed in darkness (dark convergence) with the perceived distance of the light point. Both accommodation and convergence were found to assume intermediate values in darkness. Perceived distance of the monocular light point was significantly correlated with dark convergence and unrelated to the dark focus of accommodation. It was suggested that ocular vergence is a major determinant of perceived distance under reduced visual conditions, and thus provides a possible mechanism for the specific distance tendency.     

The “soap opera” effect in story recall

When people learn a series of actions of a character, their memory is strongly influenced, we suggest, by beliefs about that character’s motives. Motives serve as schema for deciding the meaning of the actions, their importance, and their interconnections. In two experiments, subjects read and later remembered some dull activities of a character. Experimental subjects knew what this character was worrying about (e.g., an unwanted pregnancy); control subjects did not. Recall and recognition showed that motive subjects distorted many of the colorless events to be motive relevant. Although the motive schema helped connect the disparate actions, it interfered with accurate recording and recall of the details.     

Locomotion, active choice, and spatial memory in children

In two studies, children between 4 and 6 years old were tested on a radial search task requiring nonredundant sampling of eight identically labeled positions in a room. In the training phase (5 days), children made free choices by walking between positions, were passively transported in a pushchair, actively directed their own route from a pushchair, or were led on foot to positions selected by the experimenter. When tested (whether walking or directing while seated in a pushchair), children who had either walked independently or directed the experimenter while being pushed performed competently; those led on foot without spatial choice performed almost as well. Only the children who had neither independent locomotor experience nor autonomous choice performed very poorly. The results are related to neurobiological models of spatial cognition and may have implications for the transportation of children with mobility problems.     

Effects of trait anger and anger expression style on competitive attack responses in a wartime prisoner’s dilemma game

We assessed the role of trait anger and anger expression style on competitive/aggressive decision making and responding. In a 100‐trial iterated Prisoner’s Dilemma (IPD), with instructions to simulate wartime interactions, competition/aggression was defined as “attacking the opponent,” and “waiting for troop reinforcements” was the noncompetitive alternative response. Prior to play, 92 university student players completed the State‐Trait Anger Expression Inventory. They were then paired to play the IPD against partners of similar or dissimilar trait anger levels. At postplay, the State Anger scale was readministered. Results showed significant preplay to postplay increases in state anger, with greater increases shown by high trait anger players. Thus, high trait anger players were especially subject to arousal. Players in the high trait anger group made more competitive/attack responses, and they were more likely to do so when paired with a high trait anger partner. As a result of the high level of competitive/aggressive play, both groups ended with a negative troop count. Trait anger as a general personality temperament was predictive of state anger, competitive/attack responses, and the number of trials before a retaliation was made. The expressive style of anger‐control was also related to manner of play. Trait anger had strong direct and indirect effects through anger control on the number of competitive attack responses. It was concluded that trait anger, especially trait anger/temperament, and anger control difficulties may be toxic personality factors in decision making and competitive behavior. Aggr.

Overcoming Procrastination: The Effect of Implementation Intentions1

A hypothesized solution for procrastination is the formation of an implementation intention ( Van Eerde, 2000 ). University students (N = 152) were assessed using the Aitken Procrastination Inventory ( Aitken, 1982 ) and were asked to report to an experiment. Half of the participants formed implementation intentions to attend. An odds ratio indicated that participants who formed implementation intentions were nearly 8 times more likely to keep their appointments than those who did not. Low procrastinators reported more often for the experiment than did high procrastinators (Low = 49.4%; High = 30.1%), χ²(1, N = 152) = 5.84, p < .016. The interaction between implementation intentions and procrastination was not significant, χ²(1, N = 152) = 0.28, p < .60.     

Racial differences in birth outcomes: the role of general, pregnancy, and racism stress.

OBJECTIVE: This study examined the role of psychosocial stress in racial differences in birth outcomes. DESIGN: Maternal health, sociodemographic factors, and 3 forms of stress (general stress, pregnancy stress, and perceived racism) were assessed prospectively in a sample of 51 African American and 73 non-Hispanic White pregnant women. MAIN OUTCOME MEASURES: The outcomes of interest were birth weight and gestational age at delivery. Only predictive models of birth weight were tested as the groups did not differ significantly in gestational age. RESULTS: Perceived racism and indicators of general stress were correlated with birth weight and tested in regression analyses. In the sample as a whole, lifetime and childhood indicators of perceived racism predicted birth weight and attenuated racial differences, independent of medical and sociodemographic control variables. Models within each race group showed that perceived racism was a significant predictor of birth weight in African Americans, but not in non-Hispanic Whites. CONCLUSIONS: These findings provide further evidence that racism may play an important role in birth outcome disparities, and they are among the first to indicate the significance of psychosocial factors that occur early in the life course for these specific health outcomes.     

Social network members' responses to friends' breakup false alarms

Social networks influence romantic relationships through friends' support or lack of support of the union. However, the consequences of friends repeatedly telling other friends their relationship was going to end but failing to actually terminate the relationship are unclear. Guided by the false alarm effect (FAE), and data from both student (N = 273) and noncollege (N = 226) samples, it was found that breakup false alarms were associated with increases in both positive and negative responses. In addition, when participants were friends with both partners, breakup false alarms were associated with “feeling caught” between the friends. Findings generally support the FAE and paint a complex picture of how social network members react to their close friends' tumultuous relationships.     

Counseling Intimate Partner Abuse Survivors: Effective and Ineffective Interventions

This study obtained feedback from intimate partner abuse survivors (N = 104) regarding helpful and unhelpful aspects of therapy. The survivors’ narrative accounts and answers to quantitative questions were subjected to quantitative and qualitative analysis. Results suggest that survivors sought therapy to understand themselves and the abuse they endured. Clinicians’ diagnoses of codependency or assertions that survivors chose the relationship weakened the therapeutic alliance and reduced the perceived helpfulness of therapy.
