Cognitive and Interpersonal Predictors of Stress Generation in Children of Affectively Ill Parents

Stress generation is a process in which individuals, through their depressive symptoms, personal characteristics, and/or behaviors, contribute to the occurrence of stressful life events. While this process has been well documented in adults, few studies have examined it in children. The present study examines whether cognitive and interpersonal vulnerability factors to depression contribute to stress generation in children, independent of their current depressive symptoms. Participants included 140 children (ages 6 to 14) and one of their parents. During an initial assessment, children completed self-report measures assessing cognitive and interpersonal vulnerability factors to depression. Children and their parents also completed measures assessing depressive symptoms. One year later, children and their parents participated in a semi-structured interview assessing the occurrence of stressful life events in the past year. Multi-level modeling results provided strong support for the stress generation process in children of affectively ill parents and highlight the importance of considering gender and age moderation effects.

Adults sexually abused as children: Legal actions and Issues

This article first briefly discusses the problem of delayed memories and long-term effects of child sexual abuse and the current trend to bring civil lawsuits or criminal prosecutions for childhood sexual abuse. The article addresses the primary obstacle to such actions—the statute of limitations—which in most states places a time limit on when legal actions can be commenced. It describes the purpose of the statute of limitations and the need for changing or extending it in child sexual abuse cases; it then summarizes and analyzes the methods used by state legislation and judicial decisions to change or extend the statute of limitations in both criminal and civil actions. The article examines the pros and cons of bringing legal actions for child sexual abuse many years later, and concludes with a discussion regarding the current debate about the accuracy and authenticity of long-term memory and the advisability of legal reforms to extend or eliminate the statute of limitations in this area.     

Place recognition and way finding by children and adults

Children and adults were escorted on their first walk across our university campus and were periodically led off the original route during the return trip. During the return, we stopped prior to intersections on and off the original route to obtain estimates of place recognition accuracy and confidence. The subjects were then asked to point to the path that led back to the start and were corrected if wrong. Accuracy of place recognition was intermediate in a way-finding task requiring reversal of an incidentally learned novel route. However, accuracy increased as subjects were farther from the original route, indicating that the presence of novel landmarks boosted the discrimination of old and new places. Eight-year-old children were less accurate than 12-year-old children and 25-year-old adults, who did not differ in accuracy. There was a similar age difference in the ability to point to the direction to return when subjects correctly recognized that they were off route. The results are used to develop a model of way finding by place recognition.     

Is speed of information processing related to fluid or to crystallized intelligence?

Speed of information processing was examined in relation to the theory of fluid and crystallized intelligence. Sixty sixth grade children completed the Standard Progressive Matrices test and the Mill Hill Vocabulary scale, both untimed, as measures of fluid and crystallized intelligence, and three RT tasks: Memory Scanning, Picture Identification, and Sentence-Picture Comparison. As predicted, RT parameters, with the exception of slope on two tasks, were negatively correlated with scores on both tests. There were no consistent differences between the two tests in the size of correlations with RT, and partial correlations, eliminating the effects of fluid and crystallized intelligence respectively, failed to support any causal relationship between fluid and crystallized intelligence in either direction. Some limitations of the research, specifically in the possible effect of error rates on the speed-intelligence relationship, and in the application to individuals of task parameters derived from group performance, are noted.     

Concurrent validity of the Millon Adolescent Clinical Inventory as a measure of depression in hospitalized adolescents.

This study examined the concurrent validity of the Millon Adolescent Clinical Inventory (MACI; Millon 1993) in the assessment of depression among 88 adolescent inpatients. Doleful Personality and Depressive Affect scales were moderately predictive of a clinical diagnosis of depression, but both scales were strongly associated with scores on the Children's Depression Inventory (Kovacs, 1992). The Suicidal Tendencies scale was weakly associated with placement on suicide precautions. Overall, these results provide moderate support for the use of the MACI in the assessment of hospitalized adolescents.     

A computer-controlled language training system for investigating the language skills of young apes

A computer-controlled language training system was designed and constructed to enhance the objectivity and efficiency of inquiry into the language-relevant behaviors of apes. The system allows the S to gain control over the events of the 24-h day in direct correspondence with its competence in using a keyboard on which each key represents a word. Various incentives can be obtained through the selection and depression of appropriate keys in accordance with rules of sentence structure monitored by a computer. The system is flexible and allows for eventual conversation between man and ape, with the computer as the intermediary. A Teletype records all that transpires. Achievements of the chimpanzee S over the course of the first 8 months of the system’s operation attest to the worth of the system and training methods.     

Effect of mouth opening on bite-force discrimination

The purpose of this study was to determine whether different extents of mouth opening affect normal subjects' (N = 24; 12 women, 12 men) ability to discriminate differences in their interincisor bite force. Three mouth openings were selected including 50, 70, and 90 percent of maximum opening for each subject. Bite force was measured using a specially designed strain gauge scale which permitted subjects to monitor visually when their biting force equalled a preset resistance. Resistance forces of 500 and 1000 gm. were selected as standards. The procedure involved the use of a modified method of constant stimuli in which each subject was presented with a series of paired resistance settings, one at a time--the first resistance setting being the standard and the second resistance was the comparator. This paired-comparisons procedure was continued until the subjects' difference limen (DL) value (the threshold of discrimination between two forces) could be established. An analysis of variance yielded no significant differences in subjects' ability to discriminate bite force as a function of mouth opening.     

Infants' recognition memory, forgetting, and savings.

In four experiments infants of 5–6 months of age were tested for recognition memory of briefly presented visual stimuli. In the first experiment infants showed relatively more looking at a novel picture when it was paired with a picture they had just studied for 10 or 20 sec. This differential response to novelty served as evidence of immediate recognition memory. In the second experiment these same 10- or 20-sec study times were used but were not sufficient to produce reliable evidence of memory over a long (48 hr) retention interval or even as short an interval as 40 sec. The third experiment demonstrated substantial delayed recognition if a brief reexposure of materials was introduced immediately prior to the recognition test. This reminder required less than the minimal study time found necessary to produce immediate recognition memory in Experiment 1. The results of the fourth experiment indicated that the savings effects that occurred in Experiment 3 were not solely due to familiarity with the testing procedures. The implications of savings effects in infants' memory are discussed.     

Cartoons in Counseling

Frequently human foibles are portrayed in thought-provoking ways within cartoons and comic strips. Counselors, searching for new and imaginative ways to deal with counselees, can use such caricatures as stimulus material and as a technique for facilitating self-exploration and understanding. This article outlines some possibilities for using cartoons in counseling.     

Three experiences affecting spatial discrimination learning by ambulatory children

Children 1 and 3 years of age were given a two-choice spatial discrimination task. They were placed in front of a barrier and encouraged to walk around it; one route around the barrier was blocked. Three experiments studied the effects of different types of experience with this spatial problem. The first examined trial and error experience, in which the child was allowed to walk the route he or she had chosen. Although most children readily learned to choose the open route, the pattern of choices indicated that 3-year-olds were more likely to achieve a learning criterion after an error than 1-year-olds. A second experiment looked at the effects of showing the children the layout of the problem prior to trial and error experience. The 3-year-olds were again more likely than the 1-year-olds to achieve criterion after an error; furthermore, they were likely to know the correct route on the first trial. The third experiment let the children watch their parents take the correct route. This procedure eliminated age differences in performance. The initial choices of the 1-year-olds indicated that they were likely to know the correct route, and if they did not, they were just as likely to learn from their mistakes as the 3-year-olds. The data were interpreted within a mathematical model of learning. Based upon these analyses, we propose two developmental trends. One involves a growth in sensitivity to the consequences of a choice of route. The other is a progression from social learning to more independent and ideational methods of spatial problem solving.
