Predicting the difficulty of complex logical reasoning problems

The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.     

Universities are not a good place for psychotherapy and counselling training

This paper outlines eight aspects of institutional practice in university teaching that are at odds with the ethos of therapy: the linearity of university training has consequences for conceptual and cultural issues that may be antithetical to genuine therapeutic practice; certain notions about what reality is and what counts as truth may be reinforced by university trainings; academic knowledge in universities is standardized so as to sabotage therapeutic work; the university privileges a cognitive account; the university trains therapists in ways that are antithetical to the ethos of therapy; universities keep alive hierarchies that sit uneasily with the project of therapy; university training encourages the therapist to develop an identity that is anathema to many traditions in therapy; and compartmentalization of ethics in university-based trainings would run against the ethics of therapy.     

Constructing and deconstructing psychotherapeutic discourse

This paper reviews recent work on the social construction of the self in counselling and psychotherapy, and argues that we need to attend to the ways in which the therapeutic self is fashioned (a) in relation to the ‘psy-complex' as the network of theories and practices concerned with psychological governance and self-reflection in modern Western culture and (b) in the context of ‘therapeutic domains' outside the clinic and academe, domains of discursive regulation and self-expression which then bear upon the activities of professional and lay counsellors. Therapeutic domains contain repertoires, templates and complexes within which counsellors and clients fabricate varieties of truth and story a core of experience into being. I then turn to describe and assess some of the various ways in which this kind of critical reflection on therapeutic discourse and counselling practice now already underpins the work of social constructionist ‘narrative' therapists. Some attention is given to the different pragmatic and deconstructionist approaches which make the discursive constitution of the problem into the problem, either by dissolving or by externalizing the account the client presents. Here I argue that the activities of social constructionist counsellors can be viewed as forms of deconstruction-in-process (a deconstruction of the discursive frames which have been constructed by the client), but that they should not be viewed as stepping outside the discursive conditions of possibility which ground their work. the psy-complex and therapeutic domains still function as relatively enduring structures which limit the degree to which we may construct and deconstruct psychotherapeutic discourse.     

Disturbances of consciousness in dementia with Lewy bodies associated with alteration in nicotinic receptor binding in the temporal cortex

Disturbances of consciousness, including fluctuations in attention and awareness, are a common and clinically important symptom in dementia with Lewy bodies (DLB). In the present study we investigate potential mechanisms of such disturbances of consciousness (DOC) in a clinicopathological study evaluating specific components of the cholinergic system. [3H]Epibatidine binding to the high-affinity nicotinic receptor in the temporal cortex (Brodmann's areas 20 and 36) differentiated DLB cases with and without DOC, being 62-66% higher in those with DOC (F=4.5,p=.025). The were no differences between DLB patients with or without DOC in 125I-labeled alpha-bungaratoxin binding to the low-affinity nicotinic receptor, [3H]pirenzepine binding to the muscarinic M1 receptor, or in choline acetyltransferase activity. These findings provide support for the hypothesis that cholinergic activity is an important neural correlate if consciousness and suggest a mechanism of DOC in DLB involving alterations in the nicotinic receptor, composed of predominantly alpha4 and beta2 subunits.     

The role of optimism in social network development, coping, and psychological adjustment during a life transition.

The authors investigated the extent to which social support and coping account for the association between greater optimism and better adjustment to stressful life events. College students of both genders completed measures of perceived stress, depression, friendship network size, and perceived social support at the beginning and end of their 1st semester of college. Coping was assessed at the end of the 1st semester. Greater optimism, assessed at the beginning of the 1st semester of college, was prospectively associated with smaller increases in stress and depression and greater increases in perceived social support (but not in friendship network size) over the course of the 1st semester of college. Mediational analyses were consistent with a model in which increases in social support and greater use of positive reinterpretation and growth contributed to the superior adjustment that optimists experienced.     

Relationships between ability and personality:does intelligence contribute positively to personal and social adjustment?

Intelligence/personality associations were studied in four large datasets. Correlations between general ability (g) and major personality traits were generally consistent with previous findings. For other traits, an interpretation of the correlation patterning is that traits classifiable as adaptive in terms of personal and social adjustment have positive correlations with g, whilst maladaptive traits have negative correlations. Regression modelling confirmed these associations and structural equation modelling of selected traits showed that Neuroticism acts as a mediator of g on the outcome. Non-linear relationships between intelligence and personality were not found. In two of the datasets the correlation between Neuroticism and Psychoticism decreased with ability level, and the correlation between fluid and crystallised ability increased with level of Neuroticism.     

Evolutionary Psychology of Facial Attractiveness

The human face communicates an impressive number of visual signals. Although adults' ratings of facial attractiveness are consistent across studies, even cross-culturally, there has been considerable controversy surrounding attempts to identify the facial features that cause faces to be judged attractive or unattractive. Studies of physical attractiveness have attempted to identify the features that contribute to attractiveness by studying the relationships between attractiveness and (a) symmetry, (b) averageness, and (c) nonaverage sexually dimorphic features (hormone markers). Evolutionary psychology proposes that these characteristics all pertain to health, suggesting that humans have evolved to view certain features as attractive because they were displayed by healthy individuals. However, the question remains how single features that are considered attractive relate to each other, and if they form a single ornament that signals mate quality. Moreover, some researchers have recently explained attractiveness preferences in terms of individual differences that are predictable. This article briefly describes what is currently known from attractiveness research, reviews some recent advances, and suggests areas for future researchers' attention.     

The Treatment of Substance‐Abusing Clients in Multiservice Mental Health Agencies: A Practice Analysis

This article examines the work behaviors related to counseling substance‐abusing clients by mental health service providers in multiservice mental health agencies. The results support the need for specialized knowledge and skills in working with substance‐abusing clients.
