Group Work in Counsellor Training: Research and Development in One Programme

Group work as an integral part of counsellor training appears to have been under-utilised. Certainly it is the case that empirical evaluations of such group work appear rarely in guidance and counselling journals. An attempt is made to remedy these deficiencies by reviewing studies relevant to counsellor training and to report on 17 years of research and experience with group work within a counsellor training programme at a New Zealand university.     

Stressed vowel perception in word recognition

The purpose of this study was to measure subjects' ability to detect deliberate stressed, front-vowel misarticulations embedded in two-syllable words. Reaction times to words with various vowel-height misarticulations were examined for 25 women to assess the effect of a specific vowel height change on listeners' ability to recognize a word. Statistical analysis indicated no significant differences between reaction times to initial, stressed vowel changes along the height dimension, suggesting that subjects responded similarly to all vowel errors on the detection task. This finding provides further evidence that stressed-vowel information may serve as a perceptual anchor in guiding a listener during word recognition.     

An electronic audio switch

This article describes an electronic switch that allows presentation of sine wave stimuli without the often undesirable transient thump, thud, or click usually caused by ordinary electromechanical switches.     

Social psychology, ‘marital rape exemptions’, and privacy

A 50-state statutory search revealed that variations exist in marital rape exemptions throughout the United States. States handle the question of marital rape in one of three ways: (1) by abolishing the exemption for husbands; (2) by qualifying the exemption; or (3) by allowing the exemption. Although marital rape is a topic that has been largely ignored by social psychology, it is an area ripe for psycho-legal analysis. Possible relationships between social psychology, marital rape exemptions, and privacy are discussed against a background of a psychological jurisprudence.     

Neurosteroids in the Hippocampus: Neuronal Plasticity and Memory

The hippocampus, which is critically involved in learning and memory processes, is known to be a target for the neuromodulatory actions of steroid hormones produced by the adrenal glands and gonads. Much of the work of B.S. McEwen and collaborators has focused on the role of glucocorticosteroids and estrogen in modulating hippocampal plasticity and functions. In addition to hormones derived from the endocrine glands, cells in the hippocampus may be exposed to locally synthesized neurosteroids, including pregnenolone, dehydroepiandrosterone and their sulfated esters as well as progesterone and its reduced metabolites. In contrast to hormones derived from the circulation, neurosteroids have paracrine and/or autocrine activities. In the hippocampus, they have been shown to have trophic effects on neurons and glial cells and to modulate the activity of a variety of neurotransmitter receptors and ion channels, including type A gamma-aminobutyric acid, N-methyl-D-aspartate and sigma receptors and N- and L-type Ca2+ channels. There is accumulating evidence that some neurosteroids, in particular pregnenolone sulfate, have strong influences on learning and memory processes, most likely by regulating neurotransmission in the hippocampus. However, the hippocampus is not the only target for the mnesic effects of neurosteroids. Associated brain regions, the basal nuclei of the forebrain and the amygdaloid complex, are also involved. Some neurosteroids may thus be beneficial for treating age- or disease-related cognitive impairments.     

Obstacles and advocacy in children's mental health services: managing the Medicaid maze

Of federal programs available, Medicaid offers the greatest potential for serving children's mental health needs. Obstacles to children receiving services through Medicaid are largely determined by a state's policy of regulating services. State policies affect the delivery of mental health services for children in two ways: first, by determining which services to make available, and second, by specifying the conditions of access to those services. Accordingly, this article focuses on obstacles within states' policies that prevent effective utilization of services by children. Specifically, states' choices of eligibility criteria, services, and the procedural obstacles present within payment options are examined. Suggestions for future research are made.     

A comparison of the Bem Sex-Role Inventory and the Heilbrun Masculinity and Femininity Scales

This study compares two instruments which have recently been devised to measure sex-role identification, Heilbrun's Masculinity and Femininity Scales and the Bem Sex-Role Inventory. Correlations between the masculine and feminine scales of these instruments were significant for male but not female subjects; intrascale comparisons found no relationship between the Bem scales but moderate correlations between the Heilbrun scales for male subjects. There was agreement between the two measures in classifying approximately 47% of the subjects into one of the four sex-role categories. Misclassification occurred primarily on categories which have been found to show considerable overlap in personality characteristics.     

Sentence repetition and processing resources in Alzheimer's disease

Sentence processing in Alzheimer's disease (AD) has been found to be influenced by several grammatical and extragrammatical factors, including phrase structure and verb-argument relations, number of propositions/verbs, and processing resource capacity. This study examines the effects of these variables on sentence production in AD. Normal control and AD subjects were asked to repeat six types of sentences varying along the above dimensions of complexity. Subjects' processing resource capacity was measured using several verbal working memory tests. AD subjects' sentence-repetition performance was impaired compared to the normal control group. Significant effects were observed for branching direction of phrase structure, canonicity of verb-argument relations, and serial position of errors. Sentence-repetition performance significantly correlated with working memory scores. The findings are interpreted within a resource capacity theory of sentence processing.
