The latent structure of psychopathy: a taxometric investigation of the Psychopathy Checklist Revised in a heterogeneous sample of male prison inmates

A taxometric analysis of the Psychopathy Checklist-Revised (PCL-R) is conducted on a group of 409 male maximum-, medium-, and minimum-security federal prison inmates using the four PCL-R facet scores (interpersonal, affective, impulsive lifestyle, and antisocial behavior) as indicators. Results obtained from three quasi-independent taxometric procedures-mean above minus below a cut, maximum eigenvalue, and latent mode factor analysis-reveal consistent support for a dimensional interpretation of the psychopathy concept in a moderately heterogeneous sample of participants. On the basis of these results, it is concluded that psychopathy falls along a continuum and that high and low scores on the PCL-R reflect quantitative differences in degree rather than qualitative differences in kind.     

Generic health-related quality of life amongst patients employing different voice restoration methods following total laryngectomy

Three methods of voice restoration--tracheosophageal speech (TEP), oesophageal speech, electrolarynx--are available following total laryngectomy. TEP produces better voice quality compared with other methods and is assumed to result in better quality of life. Little evidence exists to support the relationship between voice quality and quality of life, however. Advertising this study through several leading laryngectomy charities resulted in the completion of 226 questionnaires (TEP = 147; oesophageal speech = 42; electrolarynx = 37) comprising the Short Form 36 (SF-36) quality of life measure and questions examining perceived voice intelligibility. Additionally, 89 questionnaires comprising only the SF-36 were completed by participants who reported having no serious medical problems, to form a healthy control group. Results indicate that improved voice quality does not result in widespread benefits to quality of life. On only a few dimensions were there differences between voice restoration method: electrolarynx and TEP better than oesophageal speech with respect to pain, TEP better than oesophageal speech with respect to role limitation: physical problems. Additionally whilst widespread differences between voice restoration methods did not occur, all three groups had a worse quality of life compared with the healthy control group. Implications of the results for the selection of voice restoration method to maximize quality of life are discussed.     

The effects of social context,source fairness,and perceived self‐source similarity on social influence: a self‐categorisation analysis

Based upon a self‐categorisation analysis of social influence (Turner, 1991), we predicted that individuals who self‐categorise with the source of a communication would align their own private attitudes more closely with the source when that source was distributively fair rather than unfair in an intragroup context. We expected this pattern to reverse in an intergroup context when the unfairness was ingroup favouring. These expectations were confirmed in a laboratory experiment (N=101). The data suggest that neither source similarity nor source fairness serve simply as persuasion cues to which individuals thoughtlessly conform. We argue, instead that, once self‐categorised, individuals: (1) actively attend to an ingroup member's behaviours and the context in which they occur, and (2) are influenced only by a source who provides some form of social identity enhancement, either by being fair in an intragroup context (Lind & Tyler, 1988) or ingroup favouring in an intergroup context (Tajfel & Turner, 1986).

Marriage and social support in a British–Asian community

People of South Asian origin represent one of the largest ethnic minority populations in Britain. However, research into the marital beliefs and practices of British South Asians has tended to conflate together different South Asian groups of different religious and geographical origins. This study focused on one large religious group originating from one region (Hindus from Gujarat) resident in one large British town, providing analyses drawn from theories of cultural values, acculturation and social identity. Seventy married couples participated in detailed interviews inquiring about the arrangement of their marriage, their attitude towards marriage, gender roles, and the formal and informal support available in times of marital crisis. Our analysis of these interviews suggested that whilst our respondents maintained largely collectivist values in the family, they also saw marriage very much as an expression of individual fulfilment. Marital choice and gender roles in marriage reflected an integrationist strategy combining the traditional cultural practices and identity priorities with the social preferences and economic realities of their new culture. Finally, social support was largely forthcoming from members of the Asian community, reflecting a degree of separation from the majority community particularly when emotional assistance was desired.

Social desirability,adequacy of social support and mental health

The extent to which the association between satisfaction with social support and mental health was due to social desirability was determined. Whether this association differed between those high and low on social desirability was also examined. Measures consisted of the Crowne – Marlowe Scale, the Adequacy of Social Integration and Attachment Indices, the General Health Questionnaire, the Zung Self‐Rating Depression Scale and four scales from the Delusions‐Symptoms‐States Inventory. The sample comprised 132 women and 93 men randomly drawn from a larger sample of 756 selected at random from the Canberra electoral roll. Although social desirability was positively associated with satisfaction with social support and mental health, the association between mental health and satisfaction with social support was little reduced when social desirability was controlled, indicating that social desirability did not account for the association between social support and mental health. The association between satisfaction with social support and mental health did not differ between those high and low in social desirability, suggesting that this association was not moderated by social desirability.

A small-to-large unit progression in metaphonological awareness and reading?

The paper reports a series of studies of reading and metaphonological processing by children in their second year in primary school(aged 6 years). An earlier study had established that, in the first year of learning, performance was characterized by a small-unit approach in which graphemes and phonemes were emphasized. In the second year, reading became more sensitiveto the frequencies of rime structures in the lexicon. Capacity to generate word analogies for nonwords also showed increasing commitment to rime-based responses, and this trend was strongly linked to reading age. The present results suggest that a small-unit approach to reading is augmented by a large-unit approach as development proceeds. This trend was reflected in performance on a test of explicit phonological awareness. When asked to report the segment of sound shared by two spoken words, Primary 1 children were poor in reporting shared rimes but relatively adept in reporting shared phonemes. During Primary 2 there was an improvement in ability to report shared rimes, and this trend was also related to reading age. These results are discussed in relation to the influence of instruction and the nature of the orthography in determining the course of reading development.     

Empirical evaluation of a model of global psychophysical judgments: III. A form for the psychophysical function and intensity filtering

In part I, a concept of ratio estimation is defined and it is shown that if such estimates depend only upon the physical ratio of the signal to the reference signal, the psychophysical function must be a power function. Assuming the same exponents for each component, an invariance condition, equivalent to a sum of power functions, is studied empirically for binaural loudness. It is fully or partially sustained for 19 of 22 respondents. Since failures may be attributable to different exponents in the two ears, the ratio of the two exponents is estimated but that fails to explain the failures. Other possible explanations are suggested. In part II, an intensity filtering model is presented, accounting for the phenomenon where monaural loudness matches show a bias depending on the matching ear. We show (a) that the existence of such a bias does not alter the prior experimental results; and (b) assuming the power function, that five respondents attenuate the opposite ear and two enhance it.
