RATINGS OF MANAGERIAL CHARACTERISTICS: EVALUATION DIFFICULTY, CO-WORKER AGREEMENT, AND SELF-AWARENESS

This research examined variables contributing to self-awareness and coworker agreement on 30 managerial characteristics. The first study collected data from 233 management students on the difficulty of rating different characteristics. It also developed reliable measures of self-protection mechanisms that may negatively influence self-awareness. Four self-protection factors were identified: Denial, Giving Up, Self-Promotion, and Fear of Failure. The second study collected self-, supervisor, peer, and subordinate ratings of the managerial characteristics to derive multiple measures of self-awareness. There was a total of 283 co-worker ratings for 36 target middle managers. The results showed that within-sample co-worker disagreement measures from Study 2 were higher for items that were perceived by the sample in Study 1 as more difficult to rate. Self-ratings were more highly related to the average of co-worker ratings than to the ratings provided by any one co-worker alone. Co-workers' ratings of the target's use of self-protection mechanisms were negatively associated with self-awareness measures. Ideas are discussed for other correlates of self-awareness and ways to enhance the value of feedback processes.     

Now you see me,now you don’t: Adapting practice through target exclusion negatively impacts motor learning

How to optimize practice through scheduling of different task components or skills is a question that has received a lot of attention in motor learning research. Consistently, schedules with high variability in the order that skills are practiced elicit better learning outcomes than schedules with low variability. Another idea is that learners should seek to reduce the uncertainty of practice outcomes, by avoiding well-learned, low error components in acquisition. To test this idea, we used a target exclusion method to prevent learners from returning to task components with low error and studied how individuals given choice over practice choose to allocate time to components of varying difficulty. In a multi-target adaptation paradigm, we compared exclusion with no exclusion methods in random-schedule, self-control and yoked, matched-schedule groups (6 groups total). To manipulate uncertainty, we excluded targets from practice once participants attained a criterion error score (mean < 5^o) from the last 5 trials to the same target. Contrary to our predictions, groups that practiced without target exclusion were more accurate in retention compared to exclusion groups; irrespective of practice schedule. Self-control groups adopted uncertainty-based practice, spending more time at difficult targets and less time at easier targets. However, there were no group differences in error, based on schedule-type (random, self-control and yoked). In conclusion, target exclusion was not an effective method for learning and did not support the efficacy of uncertainty-based practice for learning novel skills. There were benefits from keeping easier/low error skills in practice for later retention. These benefits did not appear to be related to the increased switching between skills, but could be related to increased task engagement and more optimal challenge associated with practice on a range of target difficulties, rather than the most difficult.     

A short-term longitudinal examination of young adolescent functioning following divorce: The role of family factors

The purposes of this study were to examine young adolescent functioning over a 2-year period after divorce and to assess the role of two family factors, interpersonal conflict and the parent-adolescent relationship, in predicting such functioning. One hundred and twelve young adolescents, their mothers, and their social studies teachers served as participants. One-half of the adolescent were from recently divorced families and one-half were from married families. Mothers completed measures concerning interparental conflict and the parent-adolescent relationship, adolescents completed a measure of the relationship, and teachers completed measures assessing four areas of adolescent functioning. The results indicated that adolescents from divorced families were functioning less well than those from married families. There were no changes in adolescent functioning and the parent-adolescent relationship from the first to second year postdivorce. High levels of interparental conflict in divorced families were associated with more parent-adolescent relationship problems. In turn parent-adolescent relationships problems served as the best predictor of concurrent and subsequent difficulty in adolescent functioning.This study was supported, in part, by the William T. Grant Foundation and the University of Georgia's Institute for Behavioral Research.     

Effects of difficulty and diagnosticity on choice among tasks in relation to achievement motivation and perceived ability.

The experiment is a partial replication of a study conducted by Trope. It investigates the effects of two person characteristics (achievement motive and perceived own ability) and two task characteristics (difficulty and diagnostic value about own ability) on choice among achievement tasks. In accordance with the results of Trope, it was found that high-diagnostic tasks were preferred to low-diagnostic tasks, independent of their difficulty. Trope's finding that high resultant achievers choose high-diagnostic tasks over low-diagnostic tasks to a greater extent than low resultant achievers was not replicated. However, the perceived degree of own ability affected choice behavior: When easy and difficult tasks were both high in diagnosticity, subjects high in perceived ability preferred difficult over easy tasks, whereas subjects low in perceived ability preferred easy over difficult tasks. From this latter finding it is concluded that a self-informational conception of choice behavior has to include the subjective probability of success at tasks as a determinant of choice, in addition to objective difficulty and diagnostic value.     

Task difficulty, cardiovascular response, and the magnitude of goal valence

Sixty-four young women expected to perform an easy, moderately difficult, or extremely difficult memory task with the opportunity to earn a small incentive for good performance. Cardiovascular (heart rate, systolic and diastolic blood pressure) and subjective measures were taken immediately prior to task performance. Both systolic blood pressure (SBP) responses and ratings of goal attractiveness were nonmonotonically related to expected task difficulty, with the most pronounced SBP elevations and highest goal attractiveness in the moderately difficult task condition. Product-moment correlations among cardiovascular response measures revealed a strong positive association between systolic and diastolic pressure (but not heart rate) change in the easy condition, positive relationships among all measures in the moderately difficult condition, and no significant correlations in the extremely difficult condition. Subjective measures of arousal were not affected by the task difficulty manipulation. Principal findings are discussed in terms of a theoretical model proposed by Brehm (1979) that states that motivation varies as a nonmonotonic function of the difficulty of goal attainment. Intercorrelations among cardiovascular response variables are considered in terms of their possible indication of the mechanisms underlying blood pressure changes associated with variations in motivation.     

Family relations, mental health and adherence to nutritional guidelines in patients facing dialysis initiation

This study investigated the effect of family relations on patients' adjustment to dialysis. The two main aims were to develop a family typology, and to explore the influence of family profile on the patient's anxiety, depression and adherence to nutritional guidelines. The sample consisted of 120 patients (mean age 63 years; 67.5% of men). They completed several measures 1, 6 and 12 months after dialysis initiation. The scales used were the Family Relationship Index and the Hospital Anxiety and Depression Scale. Perceived adherence to nutritional guidelines was assessed using two visual analogical scales. Results showed that family relations remained stable over time. Cluster analysis yielded three family profiles, which were named conflict, communicative and supportive families. Patients belonging to conflict families perceived themselves as less adhering to nutritional guidelines. For these patients, anxiety and depressive moods increased significantly over time, whereas mental health remained stable over time for communicative and supportive families. This research underlines that family relations are essential in global consideration of the care of patients treated by dialysis. Conflict families seem especially at risk. They should be identified early to help them adapt to this stressful treatment.     

Performance-based adaptive schedules enhance motor learning

Although investigators have shown that random scheduling of several tasks enhances learning more than blocked scheduling does, the advantages of random scheduling may be limited because it does not take into account the nominal difficulty of each task, the difference in difficulty between tasks, and the skill level of the learner in that type of schedule. The authors propose 2 new algorithms for adaptively determining the nominal difficulty and the number of trials for each task on the basis of both current and delayed performance of the learner (N = 48). The authors tested the adaptive algorithms in a 2 x 2 factorial design, and they show that the algorithms outperform random scheduling when performance is measured on a delayed retention test.     

Intermittent low-calorie regimen and booster sessions in the treatment of obesity

The present study investigated two new weight-control strategies: an intermittent low-calorie regimen and intermittent scheduling of booster sessions. A new approach to predicting patient weight loss, based on a pretreatment assessment with a highly-structured eating regimen, was also studied. Forty-eight obese patients were randomly assigned to either a Standard Behavioral weight-control condition or to an Intermittent Low-calorie Regimen (< 750 cal for 2 days/week) condition and to one of two maintenance schedules: a Spaced schedule in which the six booster sessions were held at monthly intervals, or a Massed schedule, in which four of the six meetings were held during the third month. Neither the intermittent low-calorie regimen nor the intermittent scheduling of booster sessions significantly affected weight loss. However, weight loss at 1 year was related to compliance to self-monitoring and to self-reported change in eating habits and exercise. In addition, weight loss at 1 year was related to weight loss during the initial pretreatment assessment period.     

Determinants of the Magnitude of Goal Valence: The Interactive Effects of Need,Instrumentality, and the Difficulty of Goal Attainment

An experiment was conducted in which subjects could earn either a high (14/15) or a low (1/15) chance of winning a McDonald's Big Mac hamburger by successfully performing a difficult or very difficult memorization task. During the morning hours prior to the experimental session, half the subjects did not eat (high need) whereas the rest did (low need). As predicted, anticipatory ratings of the attractiveness of the hamburger increased across task difficulty for subjects in high need given the high chance and decreased across task difficulty for subjects in low need given the high chance. Furthermore, ratings were low and unaffected by task difficulty for the low-need subjects given the low chance. An unexpected increase in attractiveness ratings among subjects in high need given the low chance provided the impetus for a second experiment. In this study, subjects, all of whom were in high need, were given either an extremely high (79/80) or an extremely low 0/80) chance of winning the hamburger given success on the difficult or very difficult task. With this stronger manipulation, the attractiveness ratings of the hamburger increased as a function of task difficulty for subjects given the high' chance and, unlike the first experiment, decreased modestly as a function of task difficulty for subjects given the low chance. Results of the two experiments are discussed in terms of the energization theory of motivation.     

Sensitivity and bias under conditions of equal and unequal academic task difficulty

We conducted an experimental analysis of children's relative problem-completion rates across two workstations under conditions of equal (Experiment 1) and unequal (Experiment 2) problem difficulty. Results were described using the generalized matching equation and were evaluated for degree of schedule versus stimulus control. Experiment 1 involved a symmetrical choice arrangement in which the children could earn points exchangeable for rewards contingent on correct math problem completion. Points were delivered according to signaled variable-interval schedules at each workstation. For 2 children, relative rates of problem completion appeared to have been controlled by the schedule requirements in effect and matched relative rates of reinforcement, with sensitivity values near 1 and bias values near 0. Experiment 2 involved increasing the difficulty of math problems at one of the workstations. Sensitivity values for all 3 participants were near 1, but a substantial increase in bias toward the easier math problems was observed. This bias was possibly associated with responding at the more difficult workstation coming under stimulus control rather than schedule control.     

Response elimination in rats with schedules of omission training, including yoked and response-independent reinforcement comparisons

After rats were trained to lever press, response elimination began with factorial combinations of fixed vs variable and adjusting vs constant omission training schedules. A time interval scheduling reinforcement remained the same in a constant schedule, and its length was increased as response rate declined in the adjusting schedule. A variable time (VT) response-independent reinforcement schedule followed response elimination to test the durability of response cessation. Experiment I included groups whose reinforcement was yoked to that received by the omission schedule groups. Rate of response elimination was faster with an adjusting than a constant schedule, and slightly faster with a variable than a fixed schedule. There were no significant differences in rate of response elimination between omission schedule and yoked groups. Shorter delay of reinforcement tended to increase rate of response elimination. In the subsequent VT durability test all groups displayed near-zero response rates. In Experiment II adjusting fixed and variable omission schedules, including yoked groups, were compared with fixed time (FT) and VT reinforcement schedules. Response elimination was slower in the FT and VT groups, and they responded more in a subsequent VT durability test. It was concluded that differential reinforcement of other behavior fails to account for these omission training effects, and suggestions were made for an analysis based on the correlation between response and reinforcement rate.     

Cross-Sectional and Longitudinal Examination of Attachment,Separation-Individuation,and College Student Adjustment

This article examined stability and change in late adolescent attachment relations and the interrelationship among attachment, separation-individuation, and college adjustment variables. Two studies are reported. In the first cross-sectional study, freshman and upperclassmen college students completed self-report measures of attachment, separation, and adjustment. In the second study, students completed measures of attachment in their freshman year and 2 years later as juniors. In junior year, students also completed several measures of separation and adjustment to college. The results of both studies suggested stability in attachment to parents, over time, for both men and women. Security of attachment proved to be inversely related to independence from parents in cross-sectional and prospective/longitudinal analyses. Security of attachment to parents was positively and pervasively associated with a variety of concurrent indexes of college student adjustment. Secure attachment assessed in freshman year also was positively associated with academic and emotional adjustment in junior year, although the longitudinal results were not as pervasive as the cross-sectional findings. The results supported the importance of current and past perceptions of attachment for understanding late adolescent development and adjustment.     

Understanding Respite Care Use by Families of Children Receiving Short-Term, In-Home Psychiatric Emergency Services

Respite care is widely believed to be an important support service for families raising a child with a disability. We report the findings of a respite care utilization study conducted within the context of a larger research and demonstration project examining three models of intensive, in-home services for children experiencing psychiatric crises. Respite care, both in-home and out-of-home, was a support service available to families in two of the three study conditions. Overall, 34% of 146 eligible families used in-home and or out-of-home respite care. Utilization was lower than the estimates developed prior to implementation, prompting an inquiry at the end of the first project year designed to maximize use and to gather more information on caregiver and service provider attitudes toward respite care. The inquiry included caregiver and provider focus groups, surveys, and enhanced data collection and analysis. Caregiver interviews indicated that many families did not fully understand what it meant to receive respite care or even that it was available to them. A comparative analysis of respite care users and non-users revealed that respite care users were more likely to have younger children, children who had a greater number of assessed functional impairments, and fewer social supports. Respite care users also reported greater difficulty managing their children's difficult behaviors.     

Spacing enhances the learning of natural concepts: an investigation of mechanisms,metacognition, and aging

In two experiments, we examined spacing effects on the learning of bird families and metacognitive assessments of such learning. Results revealed that spacing enhanced learning beyond massed study. These effects were increased by presenting birds in pairs so as to highlight differences among families during study (Experiment 1). Self-allocated study time provided evidence that more attention was paid during spaced than during massed study and resulted in no age differences in learning (Experiment 2). Metacognitive measures revealed sensitivity to the processing advantage of spaced study and to differences in classification difficulty across categories. No difference occurred in monitoring accuracy for young versus older adults. These findings provide evidence for discrimination- and attention-based accounts of the spacing effect in natural concept learning.     

Goal progress makes one happy,or does it? Longitudinal findings from the work domain

In a 3‐year longitudinal study with a sample of N=82 young professionals (44% male; age range: 28–39 years), self‐reported progress in the pursuit of personal goals was associated with affective well‐being, work satisfaction, and subjective developmental success in the work domain. Goal progress, however, did not predict an increase in affective well‐being and work satisfaction. Four constructs – goal difficulty, current work involvement, positive fantasies, and goal progress in the private domain – were selected to analyse their potentially moderating effect on the link between goal progress and well‐being increases. Goal difficulty evinced the clearest moderating effects. Goal difficulty predicted change in all outcome criteria, that is, only adults who perceived their goals as difficult to reach also reported a change in positive and negative affect, job satisfaction, and subjective developmental success over a period of 3 years.     

The visitation schedule and child adjustment: a three-year study

Frequency and regularity of visitation is studied over time for a sample of recently separated mother-custody families. Results suggest that stability of visitation is more predictive of child adjustment than frequency of visits and that these effects are manifested over time. Setting up and maintaining a visitation schedule are shown to be related to the relationship that parents establish with each other in the first year of the separation.     

Poverty,ethnicity, and risk of obesity among low birth weight infants

The independent and joint effects of family and neighborhood poverty and ethnicity upon weight trajectories from age two to six-and-a-half were examined using data from the Infant Health and Development Program (N = 985), an early intervention program for low birth weight children and families. At age two, family poverty was associated with higher body mass index (BMI), whereas neighborhood poverty and ethnicity were not. Over time, the BMI of toddlers from poor and near poor neighborhoods increased nonlinearly, while those from nonpoor neighborhoods remained stable. BMIs of Hispanic-American toddlers increased steadily over time, unlike African-American and Anglo-American toddlers. Although initially similar, over time African-American toddlers' BMIs increased more rapidly than Anglo-American toddlers. Family and neighborhood poverty and ethnicity were associated with BMI. More work is needed on how poverty and ethnicity contribute to differences in early weight gain in conjunction with sociocultural and environmental factors in the home and community.     

Instructions as discriminative stimuli (2): A within‐subject examination of the effect of differential reinforcement on establishing novel instructional control1

Abstract: Six undergraduates were exposed to a fixed‐ratio schedule with an instruction to respond slowly and to a differential‐reinforcement‐of‐low‐rate schedule with an instruction to respond rapidly when a white circle was presented on a display monitor. When a yellow circle was presented, however, the subjects were exposed to the fixed‐ratio schedule with the instruction to respond rapidly and to the differential‐reinforcement‐of‐low‐rate schedule with the instruction to respond slowly. Following this, a fixed‐interval schedule was in effect during those stimuli and instructions. Under the white circle, response rates were higher with the instruction to respond slowly than with the instruction to respond rapidly during the fixed‐interval schedule. Such control by instructions was not observed under the yellow circle. A previous study examined establishment of novel instructional control by between‐subject comparisons and found that for three of four subjects ( Okouchi, 1999 ). In contrast, the present results demonstrate the instructional control through within‐subject comparisons for all six subjects.     

Minimizing subject loss in a longitudinal study of deviant behavior

A number of techniques are described to prevent attrition of four different categories of subjects in a longitudinal study of deviant behavior.Difficult to schedule subjects required persistence, empathy and flexibility to ensure their continued participation.Reluctant subjects were persuaded to participate by taking special care to build rapport with that family.Subjects who initially refused were turned around by assuming that a subject's refusal one year was circumstantial, and approaching that subject the following year with personalized correspondence that emphasized the importance of their contribution to the research. Persistence was an important factor in successfully locating and recruitingtransient subjects.     

Mother, child, and situational correlates of toddlers' social competence

Mother, child, and situational correlates of toddlers' social competence in the second year were investigated in a sample of 24 children (11 girls, 13 boys). At 12 months, children's temperament (perceived difficulty) was assessed by questionnaire. Between 14 and 17 months, the children's everyday interaction experiences (maternal responsiveness and involvement) were observed at home. At 24 months, the children's social competence (responsiveness, use of social resources) and the quality of maternal behavior (responsiveness, availability) were assessed in a laboratory play room. The children's social competence was positively related to the contemporary (24 months) as well as the preceding (during the second year) maternal behavior. High-quality maternal behavior during the second year was associated with the child's low perceived difficulty at 12 months. Relationships between child and mother behavior particularly occurred in situations providing some challenge to the child.
