Working memory,math performance,and math anxiety

The cognitive literature now shows how critically math performance depends on working memory, for any form of arithmetic and math that involves processes beyond simple memory retrieval. The psychometric literature is also very clear on the global consequences of mathematics anxiety. People who are highly math anxious avoid math: They avoid elective coursework in math, both in high school and college, they avoid college majors that emphasize math, and they avoid career paths that involve math. We go beyond these psychometric relationships to examine the cognitive consequences of math anxiety. We show how performance on a standardized math achievement test varies as a function of math anxiety, and that math anxiety compromises the functioning of working memory. High math anxiety works much like a dual task setting: Preoccupation with one’s math fears and anxieties functions like a resource-demanding secondary task. We comment on developmental and educational factors related to math and working memory, and on factors that may contribute to the development of math anxiety.     

When Worlds Collide: Psychoanalysis and the Empirically Supported Treatment Movement

In this conclusion, I synthesize and elaborate on some of the central threads running through the contributions to the symposium on the implications of the empirically supported treatment (EST) controversy for psychoanalysis. I argue that the EST controversy brings increased urgency to discussions about the role that empirical research should play in the development of psychoanalysis and about the potential contributions of different research paradigms to the field. Different research paradigms are associated with different epistemologies and worldviews, and the dialogue between these worldviews is critical to the vitality and health of the field. On one hand, the EST movement embodies limited, mechanistic, and one-sided values, and psychoanalysis has an important role to play in challenging these values. On the other hand, the EST movement can offer an important corrective to the more insular and rarefied strands within psychoanalysis and to its tradition of argument on the basis of authority.     

Conceptualizing cultural and gendered identities in psychological therapies

This paper addresses implications for psychological therapies and practices of recognizing the varieties of ways ‘race' and gender intersect and impact on therapeutic relationships. We illustrate how ‘race' and gender have either eluded analysis or been treated in oversimplified ways that disallow their interchange and varieties of forms, and impoverish the recognition and process of therapeutic change. Debates about ‘race' and gender in psychotherapy are situated within more general discussions about theorizing whiteness as a normalized cultural absence. This is used to inform how ethnic minorities in Britain, and specifically minority women, have been represented in (and omitted from) the psychiatric and psychotherapeutic literature. Common claims about cultural specificity (or its converse, universality) in psychological therapies, the grounds on which they are offered and their discursive consequences are evaluated. The case is made for therapy as an inevitably intercultural enterprise, while also cautioning against some prevalent misconceptions of intercultural approaches. The final substantive section develops the conceptual arguments proposed in relation to debates about culturally relevant and appropriate models in psychological therapies, including a critical commentary on the uses of gender, cultural and racial ‘matching'. Finally, implications for the training and practices of mental health professionals are discussed.     

Part—whole information is useful in visual search for size × size but not orientation × orientation conjunctions

In visual search tasks, subjects look for a target among a variable number of distractor items. If the target is defined by a conjunction of two different features (e.g., color × orientation), efficient search is possible when parallel processing of information about color and about orientation is used to “guid” the deployment of attention to the target. Another type of conjunction search has targets defined by two instances of one type of feature (e.g., a conjunction of two colors). In this case, search is inefficient when the target is an item defined by parts of two different colors but much more efficient if the target can be described as a whole item of one color with a part of another color (Wolfe, Friedman-Hill, & Bilsky, 1994). In this paper, we show that the same distinction holds for size. “Part— whole” size × size conjunction searches are efficient; “part-part” searches are not (Experiments 1–3). In contrast, all orientation × orientation searches are inefficient (Experiments 4–6). This difference between preattentive processing of color and size, on the one hand, and orientation, on the other, may reflect structural relationships between features in real-world objects.     

Healing rituals with families in exile *

This paper describes work with families who have been subjected to torture and atrocity and forced into political exile. Exile is described as a state of limbo which may be resolved by involving families in rituals which reconnect them to communal life. Therapeutic dilemmas when working with families affected by torture and atrocity are discussed. The culture of refugee families is a resource which can be used to enable them to integrate experiences of atrocity and adapt to life in exile. Therapeutic strategies are discussed through case histories.     

Linking associative and serial list memory: Pairs versus triples

Paired associates and serial list memory are typically investigated separately. An "isolation principle" (J. B. Caplan, 2005) was proposed to explain behavior in both paradigms by using a single model, in which serial list and paired associates memory differ only in how isolated pairs of items are from interference from other studied items. In the present study, 2 experiments identify a critical dissociation between the 2 paradigms, challenging this unified account. Specifically, forward and backward probes were highly correlated for pairs and less so for short lists (triples). The authors asked whether the isolation principle could quantitatively accommodate this type of dissociation. A simulation confirmed that a single model incorporating the isolation principle can adequately explain this and other dissociations, supporting the common processes view.     

Combining speed and accuracy to assess error-free cognitive processes

Both the speed and accuracy of responding are important measures of performance. A well-known interpretive difficulty is that participants may differ in their strategy, trading speed for accuracy, with no change in underlying competence. Another difficulty arises when participants respond slowly and inaccurately (rather than quickly but inaccurately), e.g., due to a lapse of attention. We introduce an approach that combines response time and accuracy information and addresses both situations. The modeling framework assumes two latent competing processes. The first, the error-free process, always produces correct responses. The second, the guessing process, results in all observed errors and some of the correct responses (but does so via non-specific processes, e.g., guessing in compliance with instructions to respond on each trial). Inferential summaries of the speed of the error-free process provide a principled assessment of cognitive performance reducing the influences of both fast and slow guesses. Likelihood analysis is discussed for the basic model and extensions. The approach is applied to a data set on response times in a working memory test. The authors wish to thank Roger Ratcliff, Christopher Chabris, and three anonymous referees for their helpful comments, and Aureliu Lavric for providing the data analyzed in this paper.
