Nature of spelling errors in transcortical sensory aphasia: A case study

The nature and extent of spelling errors in a patient with transcortical sensory aphasia were investigated. The two experimental conditions required the patient to spell monosyllabic and polysyllabic words both verbally and in written form. Analysis of the spelling errors revealed partially preserved knowledge of the visual image of a word as a whole, as well as preserved knowledge of temporal order. Our patient's error patterns in both conditions were more similar than dissimilar. These findings in conjunction with results reported in the literature indicate that patients exhibiting different aphasia syndromes use separate spelling strategies.     

Analysis and synthesis of bird vocalizations: An FFT-based software system

An FFT-based software package has been designed and implemented in order to analyze and synthesize bird vocalizations. The system is flexible so that screen editing can be per-formed on either the original waveform or the Fourier coefficients of the transform. The edited coefficients of selected notes, syllables, or songs are stored for later modification or combination with other song components to compose entirely new songs. These analyses and synthesis methods have proved to be extremely useful in the elucidation of birds’ perceptive capabilities and the biological significance of their songs.     

Primary obsessional slowness: a nursing treatment programme with a 13-year-old male adolescent

A 13-year-old male adolescent inpatient with a 5-year history of primary obsessional slowness was treated using a nursing intervention programme involving prompting, pacing and shaping, or participant modelling of four types of self-care behaviour. The treatments produced an immediate increase in response rate of three of the four behaviour targets. Treatment gains were not maintained during the gradual fading of the intervention programme. Possible reasons for failure to achieve treatment maintenance are discussed in light of the literature on primary obsessional slowness.     

A comparison of stress-reduction behavioral counseling and contingent nocturnal EMG feedback for the treatment of bruxism

This study compared the efficacy of two treatment modalities (stress-reduction behavioral counseling and contingent nocturnal EMG biofeedback) on night-time bruxism. The 16 subjects (Ss) were assigned sequentially to one of four treatment groups: (1) stress-reduction behavioral counseling: (2) nocturnal biofeedback; (3) stress-reduction behavioral counseling and nocturnal biofeedback; and (4) waiting-list control group. A portable EMG unit was used to record the nightly total of electrical activity (?20 μV) from the masseter muscle 10 days before and after treatment. The three treatment procedures were found to be significantly superior to no-treatment control group. The outcome of the two treatments which made use of stress-reduction behavioral counseling, although better than the treatment which solely used nocturnal biofeedback, was not significantly better. This study demonstrates that stress-reduction skills learned while awake can have a generalized effect on stress-induced muscle activity during sleep. Implications for further research are discussed.     

Neuroticism and the recall of positive and negative personality information

Recent investigations have shown that high-N scorers preferentially process negative information about themselves. The present experiment investigated: (1) whether this effect is related to, or independent of, the well-established effects of depressed mood on information processing; (2) whether the effect is specific to self-referent information or extends also to information about others; and (3) the mechanism by which the effect occurs. High-N scorers, compared to low-N scorers, recalled more negative information about themselves but not about others, and this effect was independent of depression. In addition, the positive self-referent, but not other-referent, personality information recalled by high-N scorers was more extremely positive than that recalled by low-N scorers. Detailed examination of the data provided evidence that the idiosyncracy in information processing associated with high neuroticism is one of selective attention. The findings are discussed in relation to cognitive vulnerability to depression, certain cognitive-therapy procedures and the effects that a therapeutically-induced change in neuroticism is likely to have on an individual's memory for past emotional experiences.     

Race, ethnicity, and depression: a confirmatory analysis

This study addresses two questions: (a) Are depressive-symptom scales equally indicative of depression in different racial/ethnic groups and (b) are there mean differences between the groups in the underlying depressive disorder assessed by these scales? The data consist of interviews obtained from a large community survey of depression in Los Angeles County. Four racial/ethnic groups were considered: Anglos, blacks, English-speaking Hispanics, and Spanish-speaking Hispanics. Confirmatory factor analysis was used to test both one-factor and two-factor models of depression. An invariant factor pattern was demonstrated. No significant mean differences on a factor of Depression were found, but the groups were found to differ on a Well-Being factor. Implications for survey research on psychiatric impairment among different racial/ethnic groups are discussed.     

Internalization versus compliance: Differential processes underlying minority influence and conformity

Two experiments investigated whether minority influence and conformity operate by the same or by different processes. It was predicted that subjects who were simultaneously exposed to a majority and a minority opinion would move towards the minority in private but towards the majority in public. The results of Experiment 1 supported this hypothesis. Experiment 2 investigated three hypotheses predicting that (1) the above interaction would be replicated, (2) minorities would trigger more arguments and counter-arguments, and (3) cognitive activity would mediate internalization but not compliance. Hypotheses 1 and 3 were supported. The second hypothesis was not supported. However, minorities were found to trigger more arguments and fewer counter-arguments than majorities. The results were interpreted as supporting the dual process model.     

A Six Year Longitudinal Study of Graduate Expectations: The Implications for Company Recruitment and Selection Strategies

All job extrants formulate a set of expectations about what a new job will be like. A least in part, these expectations are shaped by their experience of the organization's selection process. What impact do these early impressions have upon subsequent job attitudes and behaviour? This article reports the findings of a longitudinal study of UK graduates from a few weeks prior to organizational entry to five or six years after commencing employment. Both the level of pre-entry expectations and the congruency of these expectations with work experience are found to correlate with subsequent job satisfaction and organizational commitment. More support is found for the congruent expectations hypotheses, and the implications of this for company selection and socialization strategies are discussed.     

Dexamethasone Does Not Prevent Seven-Day ADX-Induced Apoptosis in the Dentate Gyrus of the Rat Hippocampus

Long-term adrenalectomy (ADX) is known to result in apoptosis within the dentate gyrus of the rat hippocampus. While the underlying mechanism is still unclear, adrenal steroids appear to play a pivotal role in granule cell survival, as administration of the mineralocorticoid receptor (MR) agonists, corticosterone and aldosterone, to ADX rats results in protection against the ADX-induced effect. The consequence of administration of the glucocorticoid receptor (GR) agonists, dexamethasone and RU28362, however, is less clear, and either complete or only partial protection for the ADX animal has been reported. This study investigated further the role played by GR in the degenerative process. After establishing the characteristics of seven-day ADX-induced apoptosis in the young male Wistar rat, the effect of chronically-implanted, subcutaneous pellets containing various doses of dexamethasone and corticosterone, on ADX-induced apoptosis was studied. Both high and low doses of corticosterone were found to be protective. In contrast to some other studies, however, neither dose of dexamethasone had any obvious protective effect and rather seemed to increase apoptosis in dentate gyrus of intact animals. Intracerebroventricular infusion of dexamethasone for seven days was also found to be ineffective in preventing apoptosis, demonstrating that it is occupation of MR, rather than GR, which is crucial to dentate gyrus granule cell survival.
