Development of the concept of family in elementary school children

Two studies were conducted to examine the relation of age, gender, and family structure to children's understanding of the concept of family. In Study 1,387 children in Grades 1 through 6 were asked to classify various groupings of individuals as constituting or not constituting a family. Results showed both age and gender differences in children's conceptions of families: Younger children, especially boys, generally used concrete, absolute criteria for defining a family; younger girls were similar to older children in that they were more likely to employ abstract, relational criteria for family definition. Results also showed that children's own family structure was not related to their family definitions. In Study 2, 64 children from the original sample were given a measure of cognitive ability to examine whether differences in cognitive development or differences in socialization were a likely source of younger girls' more advanced understanding. Gender differences in cognitive ability did not emerge, suggesting that the gender effects in Study 1 reflected differences in the socialization of boys and girls. Implications of the findings for understanding children's reactions to family disruption are discussed.     

Progamming time in serial tapping responses as a function of pathway constraint

Summary This study varied the accuracy demand within a linear series of targets to investigate the effect of movement-pathway constraints on response-programming time. Sidaway, Christina, and Shea (1988) have suggested that constraints placed upon movement initiation by the demand for response precision may play an important role in determining the length of the programming process. By varying the subtended angles of a series of three targets, this experiment tested the specific prediction of Sidaway et al. that programming time may be a function of the target, within a line of targets, that subtends the smallest angle at the start position. It is this target that demands the greatest precision in the movement pathway. Subjects participated in a series of conditions in which the size and placement of the target that imposed the maximal constraint was varied. In each condition the subjects were required to strike a series of three targets with a stylus in a simple reaction-time paradigm. Analysis of the reaction-time results revealed a significant effect of size of constraint, but no effect of position of constraint. Analysis of the movementtime data dispelled movement-duration and movement-velocity interpretations of the results and intimated a possible online trajectory-correction process.Portions of these data were first presented at the Annual Meeting of the Psychonomic Society in Atlanta, Georgia, November 1989.     

Workers' compensation for law enforcement related post traumatic stress disorder

The questions of how Post Traumatic Stress Disorder (PTSD) manifests itself among police officers and their eligibility to receive workers' compensation for PTSD are explored. The nature of the police officer's occupation, the prevalence of stress-related disorders among police personnel, and the relationship of the police personality to the dynamics of the way stress is manifested are considered. The extent to which workers' compensation statutes in various states cover mental injuries is also examined, and the variables that may affect the outcome of an officer's receiving compensation for PTSD are discussed. Finally, implications for mental health professionals who testify as expert witnesses in cases dealing with police stress, as well as those who work in the assessment and treatment ofpolice personnel, are explored.     

Some differences between phonetic and auditory modes of perception

When third-formant transitions are appropriately incorporated into an acoustic syllable, they provide critical support for the phonetic percepts we call [d] and [g], but when presented in isolation they are perceived as time-varying ‘chirps’. In the present experiment, both modes of perception were made available simultaneously by presenting the third-format transitions to one ear and the remainder of the acoustic syllable to the other. On the speech side of this duplex percept, where the transitions supported the perception of stop-vowel syllables, perception was categorical and influenced by the presence of a preposed [al] or [ar]. On the nonspeech side, where the same transitions were heard as ‘chirps’, perception was continuous and free of influence from the preposed syllables. As both differences occurred under conditions in which the acoustic input was constant, we should suppose that they reflect the different properties of auditory and phonetic modes of perception.     

Issues in treatment efficacy research with alcoholics.

A variety of therapeutic strategies have been used in the treatment of alcoholic patients. Within this context, behavioral techniques have been widely employed with varying degree of effectiveness. This paper attempts to explore theoretically 2 widely used behavioral therapeutic methods, systematic desensitization and covert sensitization, along with traditional insight-oriented therapy. Possible merits and limitations of applying these treatment approaches to alcoholic patients are explored.     

Explicit syllable and phoneme segmentation in the young child

To write a language, one must first abstract the unit to be used from the acoustic stream of speech. Writing systems based on the meaningless units, syllables and phonemes, were late developments in the history of written language. The alphabetic system, which requires abstraction of the phonemic unit of speech, was the last to appear, evolved from a syllabary and, unlike the other systems, was apparently invented only once. It might therefore be supposed that phoneme segmentation is particularly difficult and more difficult, indeed, than syllable segmentation. Speech research suggests reasons why this may be so. The present study provides direct evidence of a similar developmental ordering of syllable and phoneme segmentation abilities in the young child. By means of a task which required preschool, kindergarten, and first-grade children to tap out the number of segments in spoken utterances, it was found that, though ability in both syllable and phoneme segmentation increased with grade level, analysis into phonemes was significantly harder and perfected later than analysis into syllables. The relative difficulties of the different units of segmentation are discussed in relation to reading acquisition.     

Use of a “balance-sheet” procedure to improve the quality of personal decision making: A field experiment with college applicants

This study tested the effectiveness of a “balance-sheet” or tallying procedure used to induce high school seniors to think carefully about considerations relevant to their choice of college. Students who were exposed to the balance-sheet procedure three months before their choice of college were compared with a control group six weeks after making their decision. In comparison with control subjects, students administered the balance-sheet procedure tended (though the findings were not always significant at the 0.05 level) (1) to select a wider array of alternatives in formulating the decision, (2) to take into account more self-related and fewer social considerations, (3) to express less regret and report less concern about their choice following the decision, and (4) were less interested in receiving supportive, dissonance-reducing information. The balance-sheet procedure appears to make salient the importance of the decision, helps clarify the merits of the choice alternatives, and stimulates a search for feasible alternatives.
