Indiscriminate mothering as a contextual factor in aggressive-oppositional child behavior: “Damned if you do and damned if you don’t”

Fifty-two mother-child dyads took part in a parent training program to modify coercive, antisocial child behavior. Prior to intervention, scores on 14 measures of mother-child interaction and on an index of maternal community contacts (known as insularity) were obtained for each dyad. This index was used to divide the sample into two groups (noninsular) n=21; insular n=31). The interactional measures were then compared between the groups. Insular mothers were more aversive and indiscriminate than noninsular mothers in their use of aversive behavior toward their children, while their children were more aversive than noninsular children, especially in response to aversive maternal behavior. It was concluded that research and therapeutic work with deviant families should focus not only on immediate family interactions but also on the extrafamily environment in which these interactions take place.The research data reported in this paper were generated with support of Grant No. R01-1068-58 from the National Institute of Mental Health, Crime and Delinquency Section.

Conceptual,methodological, and clinical issues in cognitive-behavioral assessment

This article reviews cognitive-behavioral assessment principles and procedures. The functions of such assessments are noted, and issues and advances in cognitive assessment are discussed. The need for integrated cognitive, behavioral, and affective assessments is then explored. Finally, conceptual methodological, and clinical issues in the integration of assessments and study of reciprocal determinants are presented.Preparation of this paper was supported in part by a General Research Board Faculty Research Award from the University of Maryland.

An investigation of planned helping behavior

It is argued that stable, individual differences in helping behavior have not generally been observed in previous research because of the type of helping studied. This paper advocates the study of planned helping behavior as opposed to spontaneous helping behavior. The results of three studies are reported. In Study 1, an instrument designed to measure level of involvement in planned helping activities was developed. Scores on this instrument were found to be stable over a 7-month period. Further analysis revealed two major types of planned helping: (a) formal, organizational helping and (b) informal helping between friends and family. Study 2 examined a variety of intrapsychic and demographic correlates of formal and informal planned helping. Study 3 found support for the hypothesis that people in helping professions have higher levels of involvement in everyday planned helping than do people in nonhelping occupations. It is concluded that the study of planned helping, although posing methodological difficulties, is a necessary adjunct to experimental research.     

Separability and integrality of global and local levels of hierarchical patterns

We used a constrained classification task to examine the perceptual relations between global and local levels in hierarchical patterns composed of many, relatively small elements and those composed of few, relatively large elements. In Experiments 1 and 3 subjects were asked to make classifications based on "form" or "texture." In Experiments 2 and 4 they were asked to classify according to the "shape" of the configuration or the elements. The results indicate that configural and elemental levels are perceptually separable for many-element patterns when processed as form and texture: Subjects could attend to either level without being affected by variation along the irrelevant dimension. However, when the same many-element patterns were processed for global and local shape, subjects could not selectively attend to either level. For few-element patterns, global configuration and local elements appeared to be perceptually integral dimensions. These results are relevant to two issues: the global precedence hypothesis and the explanations of integral and separable dimensions.     

When selective adaptation and contrast effects are distinct: a reply to Diehl, Kluender, and Parker

Two alternative conceptualizations of selective adaptation with speech have recently received attention. The adaptation level theory (AL) outlined by Diehl (1981) and a two-stage model outlined by Sawusch and Jusczyk (1981) can both account for much of the adaptation and paired-comparison data. Recently, Diehl, Kluender, and Parker (1985) proposed that all adaptation and contrast data can be accounted for by AL theory. They reported the results of a study that showed evidence of streaming in selective adaptation and claimed that their results provide a counterdemonstration to recent studies that have argued against the AL approach. In the present article, an outline of how the Diehl et al. results can be accounted for by both the two-stage model and AL theory is presented. In addition, a new set of results comparing adaptation and paired-comparison procedures is presented. These results are precisely as predicted by the two-stage model, but they can not be handled by AL theory.     

How much is an icon worth?

We report a new technique for assessing the amount of information extracted from the icon that follows a briefly presented picture. The problem of how to measure such information was formulated in terms of how much physical exposure of a picture an icon is worth. Consider two types of stimulus presentations, each with a base duration of d ms. The first is a d-ms picture followed by an icon, and the second is a d + a-ms picture not followed by an icon. How large does a have to be so that equivalent amounts of information are extracted in the two cases? To answer this question, we showed people pictures and later tested their memory for the pictures. We found that the physical exposure duration needed to reach a particular level of performance was approximately 100 ms longer when an icon was not permitted versus when the icon was permitted. This value was independent of the base duration and the luminance of the picture. Moreover, the same value was obtained using three different kinds of memory test and four different sets of pictures. We conclude that an icon is worth approximately 100 ms of additional physical exposure duration. A reasonable explanation for this robust equivalence between icon and stimulus is that the same encoding processes are responsible for extracting information from the icon and from the physical stimulus. Therefore, any variable that affects these encoding processes must affect extraction of information from the icon and the physical stimulus in an identical manner. This prediction was confirmed for one such variable, picture luminance.     

The word-superiority effect under conditions that approximate reading

Observers detected a briefly flashed target letter embedded in word, pronounceable nonword, and unpronounceable nonword contexts. The word context facilitated perception under both holistic and analytical processing strategies; the facilitative effect was enhanced when processing was analytical.     

Vowel duration in stutterers participating in precision fluency shaping

The purpose of this study was to determine the extent to which stutters manipulate vowel duration to achieve fluency after participating in Precision Fluency Shaping. Nine stutterers who read an all-voiced sentence fluently before and after therapy were selected for study. Wide-band spectrograms were made of the initial phrase of the sentences, and vowel durations were computed. Results indicated that extended vowel durations were characteristic of the fluency of stutterers posttherapy. The subject that had the highest rate of disfluency after therapy also had the shortest vowel durations. Clinical implications concerning the importance of speech rate during carryover practice are made.
