Clinical utility of the MMPI in the evaluation of adolescent suicide attempters

MMPI profiles of female adolescents hospitalized on a general pediatrics floor following a suicide attempt were compared to a control group of medically hospitalized, female adolescents referred for psychiatric evaluation. The suicide attempters had only a lower score on the K scale when compared to the control group. Results do not suggest that a single MMPI profile differentiates suicide attempters from a comparison group of adolescents with emotional difficulties. Implications of these findings are discussed.     

Perceptual sensitivity to dimensional and similarity relations in free and rule-governed classifications

Two experiments were conducted to investigate the perceptual primacy of dimensional and similarity relations in the stimulus classifications of younger and older subjects. In Experiment 1, 4- and 10-year-olds were given free classifications in which they could group stimuli according to overall similarity or identities in size, color, or orientation. Both age groups classified stimuli most frequently according to identities on separate dimensions. In Experiment 2, 4-year-olds and adults were given free classifications followed by rule-governed classifications which required them to group stimuli according to specific relations. In the free classifications, a majority of subjects in both age groups classified the stimuli most frequently according to identities on separate dimensions. In the rule-governed classifications, both age groups were more accurate when a single separate relation was required for solution than when overall similarity was required. These results support a differential-sensitivity view of perceptual development, which asserts that individuals at all ages primarily perceive and use separate relations.     

Brief report: An extension of the sequential alternating treatment design using reversals with subjects not available concurrently

This brief report proposes an extension of the traditional Alternating Treatments Design that would be acceptable to use in hospital and residential settings where subjects are often not concurrently available. Concerns about the inability of traditional designs to work in these special situations and the emergence of a “scientist–practitioner split” are discussed. An example of how the Extended Alternating Treatments Design might be used is provided.     

The applicability of verbal mnemonics for different populations: A review

The main aims of this review were to assess(1) the likelihood of learners making spontaneous use of verbal mnemonics, and (2) the extent to which learners will benefit from using verbal mnemonics. Over 60 investigations of verbal mnemonics were reviewed, most of which concentrated upon sentence mnemonics or first-letter mnemonics; although many of the studies used students as subjects, the review also considers the value of verbal mnemonics for schoolchildren, mentally handicapped people, brain-injured patients, and the elderly. On the whole, verbal mnemonics are relatively popular internal memory aids and, when compared to standard control conditions such as rehearsal, appear to be effective learning strategies for most of the populations studied, although mentally handicapped people and schoolchildren may find it difficult to produce effective mnemonics themselves; additionally, students and schoolchildren can benefit from the use of mnemonic sentences as part of more complex techniques. Comparisons between verbal mnemonics and other memory-aiding strategies have, however, given more equivocal results. A number of areas for future research are identified. In particular it is hoped to see a development of recent trends to use non-student subject, and to investigate the applicability of verbal mnemonics outside the laboratory.     

Spelunking as a manifestation of a counterclaustrophobia

Material is presented from the case history of a patient whose interest in spelunking (cave exploration) was found to be an unconscious expression of a type of counterclaustrophobia. Both oedipal and preoedipal determinants of the claustrophobic anxieties are delineated. Of particular note in this instance is the testicular element in the genesis of the patient's claustrophobia. His confusion of the movements of his testicles into his inguinal canals during childhood defecation with the movements of the feces themselves lent an special intensity to his fear of being flushed away from the mother by an expulsive anal birth from the claustrum. Childhood anxiety aroused when his testicles would become trapped in the inguinal canals was an important forerunner of the adult fear of being trapped in confined spaces. A counterphobic element of the spelunking per se was his enjoyment in hanging suspended by a rope in caves. In this manner, he was able to act out (by virtue of his body-testicle equation) his identification with, and control over, the disappearing testicles in the setting of a claustrophilic union with the mother.     

Age and sex differences in the cooperative and noncooperative behavior of pairs of American children

Game playing behavior of same and mixed sex pairs of 5-, 8-, and 11-year-old American children was compared, using a game in which cooperative behavior maximized reward. Pairs of 8- and 11-year-old children were relatively more cooperative and attained significantly more Joint Reward Goals than 5-year-old pairs. Older pairs were not maximally cooperative, however, in terms of all the dependent measures; in adjusting for initial differences on practice trials, 5-year-olds and 8-year-olds took less time than the 11-year-olds, and 11-year-old pairs of boys took significantly more time than all other pairs. In addition, cooperative behavior increased across trials, especially for the 11-year-old children.     

Duration of negative practice and the reduction of leg pounding of a traumatically brain-injured adult

This study evaluated the relative efficacy of long (1 minute) and short (15 seconds) durations of negative practice for reducing self-stimulatory leg pounding of a traumatically brain-injured adult. In individual social skill training classes, long negative practice and short negative practice were administered concurrently in an alternating treatments design. Generalization of treatment effects outside of training sessions was assessed during the client's lunch period. The results revealed that both durations of negative practice were equally effective in reducing leg pounding during training sessions. However, the effects of training did not generalize to settings in which the practice contingency was not enforced. Pounding was more frequent and negative practice somewhat less effective during periods of high social stimulation.
