Adolescents with attention deficit hyperactivity disorder: Mother-adolescent interactions,family beliefs and conflicts,and maternal psychopathology

A group of 83 adolescents with attention deficit hyperactivity disorder (ADHD) were subdivided into those with ADHD alone (n = 27) and those with ADHD and oppositional defiant disorder (ADHD/ODD, n = 56). They were compared to each other and a community control group (n = 77) on measures of family conflicts, family beliefs, maternal adjustment, and observations of mother-adolescent interactions during both a neutral and conflict discussion. Both ADHD groups had more topics on which there was conflict and more angry conflicts at home than control adolescents on parent reports. Only the ADHD/ODD adolescents reported more such conflicts, endorsed more extreme and unreasonable beliefs about their parent-teen relations, and demonstrated greater negative interactions during a neutral discussion than the control teenagers. Similarly, only mothers of the ADHD/ODD teens displayed greater negative interactions during a neutral discussion, more extreme and unreasonable beliefs about their parent-teen relations, greater personal distress, and less satisfaction in their marriages than the mothers in the control group. Most findings for the ADHD only group were between the control group and the group with mixed ADHD/ODD but did not differ from either group. Results imply that it is the combination of ODD symptoms with those of ADHD that is associated with the greater-than-normal conflicts, anger, poor communications, unreasonable beliefs, and negative interactive styles seen in ADHD adolescents. These same characteristics typify their mothers' interactions as well such that both the adolescents' ODD symptoms and maternal psychological distress (hostility) make unique contributions to the degree of conflict and anger in the parent-teen relations of ADHD adolescents.     

Visual experience, visual field size, and the development of nonvisual sensitivity to the spatial structure of outdoor neighborhoods explored by walking.

When places are explored without vision, observers go from temporally sequenced, circuitous inputs available along walks to knowledge of spatial structure (i.e., straight-line distances and directions characterizing the simultaneous arrangement of the objects passed along the way). Studies show that a life history of vision helps develop nonvisual sensitivity, but they are unspecific on the formative experiences or the underlying processes. This study compared judgments of straight-line distances and directions among landmarks in a familiar area of town by partially sighted persons who varied in types and ages of visual impairment. Those with early childhood loss of broad-field vision and those blind from birth performed significantly worse than those with early or late acuity loss and those with late field loss. Broad-field visual experience facilitates perceptual development by providing a basis for proprioceptive and efferent information from locomotion against distances and directions relative to the surrounding environment. Differences in the perception of walking, in turn, cause the observed differences in sensitivity to spatial structure.     

A developmental view of therapeutic bonding in the family: treatment of the disconnected family

Data from an ongoing research study have been used to identify a subgroup of families of severely ill, young adults who present formidable treatment challenges to the family therapist. The disconnected family is characterized by disturbances in attachment between one or both parents and the patient. In many cases, disturbances in attachment and caretaking in the family of origin are reported for the parents in these families. Disconnected families that also have intense emotional styles of relating are particularly difficult to treat. A treatment model that focuses on intergenerational attachment issues is described.     

Effect of time of day on the relationship between mood state, anaerobic power, and capacity

Mood state was estimated in six men using the Profile of Mood States questionnaire, with a "right now" directional set prior to performance of a modified Wingate power test, once at 03.00 hr., 09.00 hr., 15.00 hr., and 21.00 hr., on different days. Anaerobic power was measured as peak power output in 5 sec., and anaerobic capacity was measured as total external work performed during the 30-sec. test. Intraindividual difference scores were calculated as a subject's score minus his mean over the four tests. Multiple regression analyses showed that time of day and the Profile of Mood States fatigue score accounted for 51% of the variance in peak power and 62% of the variance in anaerobic capacity. However, the relationships between fatigue and subsequent anaerobic power and capacity reached statistical significance only at 21.00 hr. These results suggest that intraindividual differences in the mood state are related to subsequent performance. Greater than usual levels of fatigue are associated with reduced performance capacity. However, this relationship is dynamic and is dependent upon the time of day.     

Gender differences in social support and physical health

A large body of prospective data has accumulated linking social support to health, and most social scientists agree that low levels of support are associated with poor physical and mental health. Unfortunately, most of the research has been limited to White men. When women and people of color are included in the designs, the relationships between social support and physical health are more complicated. Prospective population-based studies provide evidence that low support is associated with increased risk of mortality in women. However, in several studies, results indicated that, for specific age groups, women with high social support have increased risk of mortality. Factors that may contribute to the observed gender differences in the social support-physical health relationship are discussed. Future research should include adequate numbers of women and more sophisticated measures of social support to move the field forward.     

Stories as a mnemonic aid for older learners

The effectiveness of a story mnemonic for free-recall learning was assessed in 71 community-dwelling elderly adults. Participants received 1 of 3 memory-training programs: (a) narrative story, (b) method of loci, or (c) placebo training. The stimuli consisted of 26 nouns chosen for being highly imagible and concrete. Recall was examined immediately following study of the words, after 1 hr, and after 3 days. At each testing interval, both mnemonic condition groups outperformed the placebo group. The results suggest that a story mnemonic can enhance word retention on a free-recall task.     

Reliable operant apparatus for fish: Audio stimulus generator, response button, and pellet-dispensing nipple

As part of ongoing research into the ability of koi to categorize complex auditory stimuli, we have had to develop novel apparatus. The stimulus generator presents sound from two CD drives under computer control through a new underwater speaker. The operant manipulandum is a horizontal button that eliminates spurious triggering by water turbulence and problematic response topographies. The button’s design has also been adapted for use by tilapia in an aquacultural food-preference study. The feeder uses a nipple to dispense food pellets reliably under water. In this paper, the apparatus is described in detail. Also discussed are methodological issues related to its design, as well as its usage in a pilot study in which koi learned to discriminate music from silence by using a single manipulandum with food reinforcement.     

Does Parenting Differ Based on Social Class?: African American Women's Perceived Socialization for Achievement

Research has provided some evidence of ethnic group, gender, and class differences in the socialization for achievement. However, there is little research on African American women with the exception of the studies of low-income, single mothers. To understand the similarities and differences in socialization for achievement based on social class, middle-class African American women from working- and middle-class backgrounds were studied using qualitative and quantitative methods to compare them on issues related to achievement socialization. Women from middle-class backgrounds reported that their parents had higher expectations for them and were more involved in their education than did women from working-class backgrounds. More middle-class parents expected their daughters to be successful in careers than did working-class parents. Women from working-class families did receive support from their parents but they did not have as much support as did the women from middle-class backgrounds. Women from working-class families perhaps made use of other sources to support their desire to succeed. There were no differences in perceived race-related socialization based on social class. Implications of these findings for future research are discussed.
