LEMON-JUICE THERAPY: THE CONTROL OF LIFE-THREATENING RUMINATION IN A SIX-MONTH-OLD INFANT1

Chronic, life-threatening rumination was eliminated in a six-month-old infant by squirting a small amount of lemon juice into her mouth whenever rumination or its precursors were detected. A brief suspension of this therapy demonstrated its crucial role. Lemon-juice therapy offers a practical and acceptable alternative to other therapies for rumination, namely electric shock and massive noncontingent attention. However, since this study is limited to a single case, claims as to the effectiveness of this therapy across children are premature.     

Assortative marriage and the familiality of cognitive abilities in families of extremely gifted students

The top 1% of the extremely bright students identified by the Study of Mathematically Precocious Youth (Benbow & Stanley, 1980b) were tested along with their parents, using a battery of specifically designed cognitive tests. These students represented the top 0.03% of their age group in intellectual ability. The results showed that the parents were extremely able and resembled one another significantly more than parents in the general population. In addition, the intellectually precocious children resembled their parents to a lesser extent than children of average ability resemble their parents. These results suggest that considerable assortative mating has occurred among the parents of these extremely gifted youth, but that extreme giftedness cannot be predicted reliably solely as a result of the mating of bright parents.     

Psychometric and CT scan measurements in a case of crossed aphasia in a dextral

A case of crossed aphasia with lesion deep to the right supramarginal gyrus was studied to determine (1) if this patient behaved similar to patients with the same lesion site in the left hemisphere, (2) if visuospatial deficits were present, and (3) if the CT scan asymmetries were similar to those of other right-handers. Speech and language skills were similar to those patients with similar lesions in the left hemisphere. Visuospatial and arithmetic deficits were similar to those described after right-hemisphere and left-hemisphere damage. CT scan asymmetries were atypical. These results provide behavioral and neuroradiological confirmation of atypical hemispheric dominance.     

Blood phobia—beware

In every day life, many people complain that they are afraid of the sight of blood. Stories of trainee medical doctors fainting on first witnessing an operation abound. Many people turn away from films of operations. Despite this, there are few accounts of the treatment of patients presenting with blood phobia as a main complaint. Standard texts on phobias (e.g. Marks, 1969; Rachman, 1974) do not mention it, nor do texts on behavioural treatment (e.g. Yates, 1970). The purpose of this short report is to describe the treatment of a long-standing, circumscribed blood phobia in a 16 yr old boy, and to draw attention to some special considerations surrounding the treatment of blood phobic patients.     

A gentzen system for conditional logic

Conditional logic is the deductive system , where is the set of propositional connectives {, ,} and is the structural finitary consequence relation on the absolutely free algebra that preserves degrees of truth over the structure of truth values C, . HereC is the non-commutative regular extension of the 2-element Boolean algebra to 3 truth values {t, u, f}, andf<u<t. In this paper we give a Gentzen type axiomatization for conditional logic.Presented byJan Zygmunt     

Macrosocial determinants of social integration: Social class and area effect

Theory and research on social support have paid little attention to the existence of important macrosocial variables determining level and content of social relationships. This study examines variations in social integration as a function of social class and residential area characteristics. Results for 234 subjects living in high and low risk neighbourhoods indicated that differences between higher and lower social class groups follow different patterns in different residential areas. Also, same social class position appeared to have different significance as a function of residential area characteristics. The levels of three social integration measures—community integration and satisfaction, community association and participation, and contribution in community organizations—were significantly higher for lower class in low risk neighbourhoods than in high risk ones. However, significant differences were found in only one measure for higher social class groups, with higher levels of community association and participation in high risk neighbourhoods than in low risk ones. The discussion examines a ‘social impoverishment’ hypothesis for high risk environments, and proposes possible protective factors for higher status residents. Relations between formal and informal sources of support, and implications for social intervention strategies are also considered.     

Perceived Causes and Consequences of Property Rights to Jobs

We report two studies of property rights to jobs. Perceptions of having or not having a property right were manipulated in a vignette in the first study. Having a property right was viewed as being associated with increased commitment, organizational citizenship behaviors, willingness to sue for wrongful dismissal and decreased absenteeism and turnover in a sample of 202 undergraduates. In a second, self-report study property rights were associated with increased organizational commitment, increased perceptions of control at work, and organizational tenure in a sample of 95 clerical employees.
