Cognitive functioning and neuroticism in an elderly community sample

The relationship between neuroticism and cognitive functioning was investigated using data from a community survey of the elderly. Contrary to Pearson (1993, Personality and Individual Differences, 14, 265–266), neuroticism was related to poorer performance on a number of cognitive measures, but the pattern of correlations differed between men and women. For men there were correlations with a dementia screening test and with tests of episodic memory and fluid intelligence, while for women there were correlations with reaction time measures. It is hypothesized that correlations with neuroticism reflect the effect of chronic stress on cognitive ageing.     

Explicit and implicit memory in dementia and normal ageing

Summary In two experiments, young subjects, healthy elderly subjects (spouses), and highly intelligent elderly subjects (elite elderly), were compared with dementia patients in a variety of explicit and implicit memory tasks, to investigate two issues: whether priming in Alzheimer-type dementia is contingent upon the presence of pre-existing representations, and whether intelligence modulates performance in explicit memory tasks in healthy ageing. Dementia patients performed as well as spouses in a homophone-spelling task. Moreover, they established new contextual associations when memory was tested by word-stem completion. The hypothesis that priming in dementia is contingent upon pre-existing memory representations was not supported. Spouses, elite elderly, and young subjects did not differ in their ability to recognize correctly recently heard stimuli or to complete word stems. However, recall of lists of words and paired associates was better in both young and elite elderly subjects than in spouses. It is concluded that intellectual capacity rather than chronological age in healthy subjects modulates performance in explicit-memory tasks.Now at The Social Psychiatry Unit, Australian National University, Canberra, ACT, Australia     

Shame and fragmentation in the marital dyad

The paper outlines an expansion of object relations theory to account for fragmentation and shame. This expansion promotes a better psychodynamic perspective on the type of marital conflict escalation that occurs when each spouse turns to the other for empathic receptiveness while that other is also in a disorganized and vulnerable state of mind. Escalation occurs when spouses have different needs for safety and optimum distance and when the shame generated by continued exposure of these needs is not acknowledged. Clinical precepts promoting a focus on fragmentation and acknowledgement of shame are elaborated.     

A factor analysis of women's measurements taken for garment and pattern construction

In order to facilitate garment and pattern construction, a research which involved taking a minimum of fifty-five measurements on several thousand women was conducted by the Bureau of Home Economics. Partial correlations with age held constant were computed for a representative group of 4,128 of the women. The correlations among twenty-nine of these variables served as the basis of the present study. By a combination of the multiple-group and the centroid method of factoring, five factors were extracted. After twenty-nine rotations, simple structure was evident, and the factors were interpreted as bone length, size of joints, circumference below the waist, circumference of extremities, and circumference above the waist. The intercorrelations of the primaries were computed, and two second-order factors were extracted. One of these seems to be primarily related to the growth of fatty tissue and the other to the development of the bones.The author wishes to express her appreciation to Professor L. L. Thurstone and to the members of the Psychometric Laboratory Staff for advice relative to this study.     

The effects of progressive sleep loss on a lexical decision task: Response lapses and response accuracy

A lexical decision task was used in a paradigm testing the effects of sleep loss and fatigue on performance during a 72-h period of sleep deprivation. The data were partitioned into categories of response lapses, response accuracy, and the signal detection measures of discriminability (d’) and bias (β). Response lapses increased as a function of sleep loss and were fitted best by a composite equation with a major linear component and a minor rhythmic component. Response accuracy decreased as a function of sleep loss, with the rate of decrease being greater for nonwords than for words. Although d’ was higher for right visual field (RVF), it decreased for both fields almost linearly as a function of sleep deprivation. The rate of decrease for RVF stimulation was greater than for left visual field (LVF) stimulation, β did not change monotonically as a function of sleep loss, but showed strong circadian rhythmicity, indicating that it was not differentially affected by sleep loss per se.     

Orthographic and phonological activation in auditory and visual word recognition

A discrete-trials color naming (Stroop)’paradigm was used to examine activation along orthographic and phonological dimensions in visual and auditory word recognition. Subjects were presented a prime word, either auditorily or visually, followed 200 msec later by a target word printed in a color. The orthographic and phonological similarity of prime-target pairs varied. Color naming latencies were longer when the primes and targets were orthographically and/or phonologically similar than when they were unrelated. This result obtained for both prime presentation modes. The results suggest that word recognition entails activation of multiple codes and priming of orthographically and phonologically similar words.
