Random Generation and the Executive Control of Working Memory

A series of experiments explores the capacity for generating sequences of random responses, relating it to the central executive component of working memory. Experiment 1 shows a broadly similar pattern of redundancy increasing with speed of generation for both the verbal generation of digits and the manual pressing of keys. In both cases deviations from randomness are shown to reflect the increasing use of a limited number of stereotyped response sets. The remaining experiments use keyboard generation. Experiment 2 demonstrates that concurrent immediate serial recall decreases randomness, and that longer recall sequences produce less random output. Experiments 3 and 4 show that whereas simple counting has no effect on randomness, serial recall, semantic category generation, and concurrent digit generation have substantial effects, and a concurrent fluid intelligence test has the greatest influence on the randomness of key pressing. It is suggested that the task of random generation resembles that of category fluency because it requires the subject to switch retrieval plans and inhibit repetition. On this basis it is predicted that a task involving repeated switching of categories will interfere with generation, despite being predictable and having a low memory load. Experiments 5 and 6 confirm this prediction. Strengths and limitations of the switching hypothesis are discussed, as are the implications of our results for the analysis of executive processes.     

Runword: An IBM-PC software package for the collection and acoustic analysis of speeded naming responses

Researchers generally collect two dependent measures from most types of speeded responses: reaction time and error proportion. Recently, experimenters have tested lexical theories using alternative empirical measures, such as response force in decision tasks and response duration in naming tasks. We offer a set of software tools that expands the battery of dependent measures normally available to naming experimenters to include various duration and intensity measures of digitized voice recordings. This article explains the functionality, programming logic, and theoretical motivation behind each measure, as well as the software to support digitized naming experiments. The software runs in DOS on IBM-PC-compatible hardware with SoundBlaster 16-bit sound cards, and it takes advantage of the decreasing costs of hard-drive space and digital sound cards.     

Face-to-face and at a distance: The mediation of guidance and counselling through the new technologies

The hitherto widely-held assumption that the counselling interaction should be conducted face-to-face, while other activities within the overall guidance process could be supported by computer, is re-examined. Recent computer-mediated information and communications technologies are reviewed, and their implications for guidance and counselling as a whole are explored. While fears are still current that human relations will be mechanised through the use of the information and communications technologies, it is contended that human relations will be changed but not necessarily diminished. Comparisons are drawn with the ways in which open and distance learning have brought a re-examination of what is understood to be a 'real' teaching interaction. It is suggested that practitioners in the fields of guidance and counselling must similarly be prepared to manage radical change.     

A Systems/Dialectical Model of Supervision: A Symbolic Process

Although there has been a proliferation of models of supervision in the marriage and family therapy literature recently, most tend to focus on methods rather than on the process of supervision. The model presented here is grounded in developmental concepts and focuses on student learning through a dialectical process of cognitive and emotional growth and incorporates three stages: 1) developing relationships; 2) breaking impasses, and 3) orchestrating changes. Students discover that supervision becomes isomorphic with relationship issues that arise in their therapy sessions. Dialectical in nature in that each stage is characterized by the resolution of contradictory emotions, the supervision process helps supervisees experience emotional shifts in their interactions with others, referred to as emotional restructuring.     

Barriers to Adherence to Child Assessment Recommendations

We conducted a one-year follow-up study of child psychoeducational assessment cases to examine whether and how the assessments were helpful to families. The current report focuses on parents’ views of their child’s assessment as well as the parents’ adherence with the written recommendations provided to them following their child’s assessment. Fifty-one of 72 eligible parents whose child received an assessment in an urban, Midwest university clinic participated. Based on semistructured interviews with the parents about the assessment recommendations, we grouped the recommendations and any barriers to adherence the parents mentioned into categories, and we also rated the clarity and complexity of the recommendations. Findings showed that, on average, parents identified the assessment process as useful and attempted or fully adhered to 71.5?% of recommendations. Parents reported the lowest adherence when referrals were recommended for their child to be seen by other professionals such as a pediatrician or psychiatrist; and they cited significantly more stigma barriers for recommendations to seek counseling/therapy or psychotropic medication than for recommendations pertaining to changes at home or school. Higher parental compliance was predicted by a combination of parents reporting fewer barriers and receiving more home based recommendations. The results support the utility of psychological assessments from parents’ perspectives and suggest ways in which psychologists may increase the likelihood that parents will adhere to their recommendations.     

The Beavers, McMaster and Circumplex clinical rating scales: a study of their sensitivity, specificity and discriminant validity

To assess the sensitivity and specificity of clinical rating scales from the Beavers, McMaster and Circumplex models of family functioning videotapes of sixty families engaging in a standardized family task interview were rated using the three rating scales. The sixty families included twenty containing a child with an emotional disorder, twenty containing a child with a mixed disorder of emotions and conduct, and twenty in which none of the children presented with clinically significant difficulties. The three rating scales accurately classified 85-90% of normal controls, 70-90% of cases containing a child with a mixed disorder of emotions and conduct, and 55-65% of families containing a child with an emotional disorder. On the rating scales, the Beavers and McMaster models showed particularly high levels of sensitivity in detecting clinical cases, whereas the Circumplex rating scale was particularly good at classifying non-clinical cases accurately.     

Thomas Wolfe: Study of a Wanderer

Thomas Wolfe was an American novelist who in his short and tragic life (1900-1939) was preoccupied with themes of lost youth, memory, transience and an insatiable wandering. Wolfe was preoccupied with what I have seen, felt and thought. He was a wanderer who in his brief life made seven voyages to Europe and compulsively explored that continent. He would never own a home or a piece of land. He rarely lived in an apartment for more than a year and more commonly for just a few months. The purpose of this paper is to explore the meaning of Wolfe's tormented wandering and his endless searching. It will be my thesis that Wolfe demonstrated an inability to mourn. His writings are an attempt to recapture his past and to restore a lost world. Emphasis will be placed on themes of loss and mourning, insatiable hunger and desire, preoccupation with transience and death, and a search for that which was lost.     

Confucian Ethics and the Critique of Ideology

The debate between Hans-Georg Gadamer and Jürgen Habermas provides a fresh perspective from which Confucian philosophy may be approached. In this paper, focusing on the Lunyu (Analects), I argue that the sayings of Confucius reflect an essentially 'conservative' orientation, finding in tradition a reservoir of insight and truth. There is a critical dimension to it in that ethical reflection and self-cultivation would enable the individual to challenge particular claims of tradition. However, can self-cultivation transcend tradition as a whole and enable the individual to effect radical change? Following the strategy of Habermas' critique of Gadamer, what happens if tradition is systemically corrupt? In this discussion, rather than taking tradition generally I will focus on the concept of ritual (li) to suggest how the Lunyu seeks to crystallise the wisdom of the past into an ethical guide. The conclusion I draw is in the main a Gadamerian one. Committed to a critical appropriation of tradition, Confucian philosophy seeks ethical renewal from within, on the premise that through incremental change self-cultivation can make a real difference in the quest for moral excellence.
