Relations between infant irritability and maternal responsiveness in low-income families

Relations between infant irritability and maternal responsiveness at 12 and18 months were investigated in low-income mother-infant dyads. Emphasis was placed on whether results varied according to measurement strategies, infant gender, or level of maternal social support and satisfaction with that support. Irritability was measured separately through observation and maternal report, responsiveness was measured observationally, and maternal social support and satisfaction were self-reported via questionnaire. Concurrent relations between irritability and responsiveness were, in general, negative and were larger when irritability was measured observationally rather than by maternal report. Correlations were similar across gender. No longitudinal relations were found between irritability and responsiveness. Amount of maternal social support was weakly related to responsiveness and to responses to infant irritability, and the nature of these relations was unexpected. Irritability-responsiveness relations varied as a function of measurement strategies, which may in part explain mixed findings in the empirical literature.     

Stability in alexithymia levels: A longitudinal analysis on various emotional answers

Alexithymia refers to a specific disturbance in emotional processing that is manifested through difficulties in identifying and verbalizing feelings, and a tendency to focus and amplify the somatic sensations accompanying emotional arousal. The main purpose of the present study was to investigate the stability levels of alexithymia related to changes in emotional distress levels caused by university exams at two different times: after and during the exams. We carried out a 17-week follow-up on 36 university students, alexithymic features and self-reported emotional distress (anxiety, depression and somatic illness) were measured. Whereas emotional distress measures changed significantly during the follow-up period, the degree of alexithymia remained unchanged. We conclude therefore that alexithymia presents a constant trait in non-clinical samples, in contrast to anxiety and depression, which are state phenomena, influenced by stress levels.     

The Development of Early Externalizing Problems Among Children from Low-Income Families: A Transformational Perspective

The present study examined pathways leading to early externalizing problems from age 1 to 31/2 in a design that took advantage of our knowledge of normative progression and normative socialization as well as findings from research on risk. A sample of 130 low-income participants was followed longitudinally from 12 to 42 months using observational measures of developmentally salient parenting and child disruptive behavior to predict early externalizing problems. Results are best accommodated by concepts such as transformation and transaction from developmental psychology. For boys, both child and parent variables predicted later externalizing. For girls and boys, the interaction between child noncompliance and maternal rejection was significant.     

Fragmenting pictures on the apple macintosh computer for experimental and clinical applications

A set of procedures implemented in Microsoft BASIC is described that creates fragmented versions of pictures scanned into the Apple Macintosh, stores them as resource files, and presents them in a computerized perceptual memory test. A total of 150 pictures were selected from the Snodgrass and Vanderwart (1980) set for fragmentation. The perceptual memory test provides for five forms of 30 pictures each, divided into two sets of 15 that serve alternately as the training or old set and the new set. A training set of 15 pictures is presented for identification during the first (training) phase of the test. The second (test) phase presents the training pictures again, randomly mixed with 15 new pictures for identification. The performance of 100 subjects on the memory test is presented, along with results for each form. Overall, subjects showed improvement on the task with practice (skill learning), indexed by a decrease in thresholds from the training set to the new set. Subjects also showed large savings for the repeated pictures (perceptual learning), indexed by a decrease in thresholds from the new to the old set.     

Depression in child psychiatric inpatients: Cognitive and attributional patterns

Cognitive and learned helplessness models of depression view maladaptive cognitive and attributional patterns as core features of depressive disorders. This study examined cognitive and attributional patterns in depressed children, nondepressed children, and a subgroup of remitting depressives who had histories of depression but were not reporting depressive symptoms when evaluated during the first 2 weeks of hospitalization. When compared with nondepressed controls, depressed children reported significantly more hopelessness, more negative self-perceptions, and negative self-perceptions across a wider variety of domains, and they displayed more dysfunctional attributional styles. While 55% of depressed children displayed pervasive maladaptive cognitive patterns, the other 45% of depressed children scored more similarly to nondepressed children, suggesting that childhood depressive disorders may be heterogeneous with respect to cognitive patterns. Contrary to the notion of traitlike depressive cognitive and attributional patterns that persist after the remission of depressive episodes, children with remitting depressions scored similarly to nondepressed children.Partial support for this project was provided by a grant from the John D. and Catherine T. MacArthur Foundation as part of their Network on Risk and Protective Factors in the Major Mental Disorders. I wish to thank Donald Guthrie for providing statistical consultation, Gwen Gordon for her computer assistance, and Niels Mueller and Jean Keller for their help with data collection.     

LATERALIZATION FOR FACIAL EMOTIONAL BEHAVIOR: A METHODOLOGICAL PERSPECTIVE*

Recent attention has focused upon the neuropsychological mechanisms underlying facial emotional expression. The greater intensity of expression and more extensive muscular involvement of the left hemiface have suggested right hemisphere dominance in the expression of emotion. This interpretation is based on the fact that the lower portion of the face is predominantly innervated by the contralateral cerebral hemisphere. The current paper reviews a series of studies on (a) facial asymmetry in normal subjects, (b) facial emotional expression in brain-damaged subjects with unilateral lesions, and (c) peripheral factors mediating facial expression findings. Neuropsychological mechanisms underlying emotional processing are also discussed. Our finding of left-sided facial asymmetries in normals is underscored by our finding that right brain-damaged patients are impaired in the expression of facial emotion. Finally, our studies have demonstrated that the asymmetries in normals and the deficits in patient populations are not artifacts of hemiface size and mobility or facial paralysis and apraxia. Taken together, these studies provide evidence that the right hemisphere is specialized for the expression of facial emotion.     

Intellectual,academic, and adaptive functioning of Tourette syndrome children with and without attention deficit disorder

The intellectual, academic, and adaptive strengths and weaknesses of 30, medication-free children (M = 10.5 years) with Tourette syndrome (TS) were assessed with a battery of standardized psychoeducational measures and the Vineland Adaptive Behavior Scales. Results indicated significant relative weaknesses in mental and written arithmetic, and relative strengths in reading achievement and abstract, logical thinking. Socialization skills emerged as a significant weakness in adaptive functioning. Comparisons between TS children with attention deficit disorder with hyperactivity (ADD-H) (n = 19) weakness in both groups in all areas assessed, but significantly lower performance IQs in TS subjects with ADD-H. These findings are discussed in relation to future research with TS children.     

Addictive personality traits in bulimic patients

Forty-five female patients attending for treatment for bulimia nervosa completed the EPQ and an Impulsiveness Inventory (I₇). An Addiction score, derived from items on the EPQ, was obtained confirming that this group of bulimic patients score almost as high as drug addicts and certainly well above the normal range. On individual personality scales, the bulimic Ss scored higher than normals on N, P, Imp and Emp, but lower on E, Vent and Social Desirability.
