Contrast class cues and performance facilitation in a hypothesis-testing task: evidence for an iterative counterfactual model

Hypothesis-testing performance on Wason’s (Quarterly Journal of Experimental Psychology 12:129–140, 1960) 2–4–6 task is typically poor, with only around 20% of participants announcing the to-be-discovered “ascending numbers” rule on their first attempt. Enhanced solution rates can, however, readily be observed with dual-goal (DG) task variants requiring the discovery of two complementary rules, one labeled “DAX” (the standard “ascending numbers” rule) and the other labeled “MED” (“any other number triples”). Two DG experiments are reported in which we manipulated the usefulness of a presented MED exemplar, where usefulness denotes cues that can establish a helpful “contrast class” that can stand in opposition to the presented 2–4–6 DAX exemplar. The usefulness of MED exemplars had a striking facilitatory effect on DAX rule discovery, which supports the importance of contrast-class information in hypothesis testing. A third experiment ruled out the possibility that the useful MED triple seeded the correct rule from the outset and obviated any need for hypothesis testing. We propose that an extension of Oaksford and Chater’s (European Journal of Cognitive Psychology 6:149–169, 1994) iterative counterfactual model can neatly capture the mechanisms by which DG facilitation arises.     

Anticipatory nausea and vomiting among cancer patients: A Review

Abstract

Anticipatory nausea and vomiting (ANV), as a side-effect of cancer chemotherapy, is a well recognized phenomenon. The literature is reviewed for data on: prevalence rates, factors contributing to onset and psychological treatments used to attempt a remission in the symptoms. From the available evidence it appears that ANV is a substantial problem with one major review indicating an average combined prevalence of 32%. Although explicable using a conditioning model it has a complex aetiology with emotional and cognitive elements, as well as specific pharmacological factors, playing a role in onset. ANV appears to be responsive to psychologically-based treatment methods, with a good outcome overall. However, more process evaluation is needed in order to understand aetiologic and treatment mechanisms and to determine how best to treat cases of ANV with different aetiologies. It is considered that procedures for identifying and referring patients with ANV should be routinely incorporated into the care of cancer patients receiving repeated cycles of chemotherapy.     

Inattention,working memory,and academic achievement in adolescents referred for attention deficit/hyperactivity disorder (ADHD)

This study investigated the role of inattention and working memory in predicting academic achievement in 145 adolescents aged 13 to 18 referred for attention deficit/hyperactivity disorder (ADHD). Path analysis was used to examine whether auditory-verbal and visual-spatial working memory would mediate the relationships between classroom inattention symptoms and achievement outcomes. Results provide support for the mediational model. Behavioral inattention significantly predicted both auditory-verbal and visual-spatial working memory performance. Auditory-verbal working memory was strongly associated with adolescents' achievement in reading and mathematics, while visual-spatial working memory was only associated with achievement in mathematics. The path from inattention symptoms to reading was partially mediated by the working memory variables, but the path from inattention to mathematics was not mediated by working memory. The proposed model demonstrated a good fit to the data and explained a substantial amount of variance in the adolescents' achievement outcomes. These findings imply that working memory is a risk factor for academic failure for adolescents with attentional problems.     

Handling and self-handling: An object relations perspective on leisure exercise

This paper considers participation in exercise activities as a form of ‘self-handling’. The focus is on individual exercise rather than on activities, such as those involved in some sports and martial arts, which involve pair or group interaction.

The author suggests that the way in which physical activity is used, abused, or avoided in adult life is linked to the quality of primary relationships and in particular to childhood experiences of handling (Winnicott 1962a, 1970). She suggests that exercise evokes ‘memories-in-feeling’ (Klein 1957) of early experiences of handling and is thus essentially object related. A number of different psychic functions of exercise are considered in relation both to theory, particularly Winnicottian theory, and to clinical material.

As we are all aware, not everything a client does in the external world is raised for consideration in the context of the therapeutic relationship. The author reflects on the need to consider the meaning of the client's introduction of the subject of exercise into the therapeutic discourse, as well as the meaning of the physical activity itself.     

Soul pain and the therapeutic use of ritual

Abstract

This paper will explore the relationship between ritual and transformation. It will show how a therapist and a monk work together to create sacred spaces in which individuals can experience transformation of and through their personal histories, linking their past, present and future to address their soul pain through ritual.

It is illustrated with case studies which will demonstrate the phases of ritual work which are collectively important as part of the psycho-dynamic therapeutic process.     

Migration: Vocational perspectives on a complex and diverse transition

This paper outlines the origins of this special issue: a UK Economic and Social Research Council supported seminar series on ‘Careers and Migration’. The series elucidated a number of salient (though under-researched) issues: migration as a diverse and complex process; the loss, recovery and reconstruction of career capital as central in the migration experience; insecurity, security and their dynamic interplay; the salience of relationships with family, compatriots and communities in migrants' career development; and the appropriateness of creative approaches in researching migrants' careers. The seven articles, written by interdisciplinary authorial teams (sometimes working in different occupational sectors) contribute to our understandings of these pressing concerns.     

The Cognitive Reflection Test as a predictor of performance on heuristics-and-biases tasks

The Cognitive Reflection Test (CRT; Frederick, 2005) is designed to measure the tendency to override a prepotent response alternative that is incorrect and to engage in further reflection that leads to the correct response. In this study, we showed that the CRT is a more potent predictor of performance on a wide sample of tasks from the heuristics-and-biases literature than measures of cognitive ability, thinking dispositions, and executive functioning. Although the CRT has a substantial correlation with cognitive ability, a series of regression analyses indicated that the CRT was a unique predictor of performance on heuristics-and-biases tasks. It accounted for substantial additional variance after the other measures of individual differences had been statistically controlled. We conjecture that this is because neither intelligence tests nor measures of executive functioning assess the tendency toward miserly processing in the way that the CRT does. We argue that the CRT is a particularly potent measure of the tendency toward miserly processing because it is a performance measure rather than a self-report measure.     

Teachers' attunement to students' peer group affiliations as a source of improved student experiences of the school social-affective context following the middle school transition

A randomized control trial examined the impact of a professional development program on rural teachers' attunement to student social dynamics, and the influence of teacher attunement on students' school experiences. In intervention schools serving Latino and White rural early adolescents, teachers (N = 14) received training on social dynamics and aspects of early adolescent adjustment; control school teachers (N = 12) received no training. Social cognitive mapping procedures assessed and compared students' and teachers' perceptions of peer groups; structured observations assessed teachers' management of social dynamics. Students (N = 225) self-reported their perceptions of the school social-affective context. Intervention and control schools differed on teacher attunement and management of the social environment. Students whose teachers were more attuned to peer group affiliations evidenced improved views of the school social environment. Findings are discussed in terms of attunement as an element of teachers' invisible hand, and for teachers' role in promoting productive contexts for students during the middle school transition.
