Emotions as ecosystemic adaptations

Despite Gregory Bateson's interest in emotion and culture, the potential for understanding emotion systemically and culturally was lost very early in the mainstream development of family therapy, partly as a reaction to the dominant psychiatric‐psychoanalytic paradigm of North America at the time. In those pioneering years, to take emotion seriously was to risk appearing stuck in a one‐person psychology. In an interesting paradox, it is relational psychoanalysts and parent–infant researchers such as Beatrice Beebe and Frank Lachmann who have recently turned to systems theory to give a fuller account of emotions and emotional regulation in self and relationships. The author draws on their ideas together with the work of Peter Fonagy, Patricia Crittenden, Jessica Benjamin, Britt Krause and others to sketch briefly an ecosystemic theory of emotional expression. This sketch is used to give contextual meaning to two contrasting clinical topics in relation to anger: self‐harm and conduct ‘disorder’.     

Horizontal and vertical attentional orienting in Parkinson’s disease

Patients with Parkinson’s disease (PD) typically suffer from an asymmetric degeneration of dopaminergic cells in the substantia nigra, resulting in right-sided (RPD) or left-sided (LPD) predominance of motor symptomatology. As the dopaminergic system is also involved in attention, we examined horizontal and vertical orienting of attention in LPD (N = 10), RPD (N = 9) and controls (N = 10). Four LPD patients demonstrated left neglect and three LPD patients demonstrated neglect for the upper visual field. LPD patients demonstrated a slower performance in detecting targets in the left hemifield and did not demonstrate a validity effect, unlike RPD patients and controls. RPD patients performed similar to controls, with the exception of one patient showing left and another showing right neglect, and two RPD patients demonstrated lower neglect. In sum, horizontal and vertical orienting of attention can be affected in Parkinson’s disease – particularly in LPD – from very subtle slowing to clinically detectable horizontal and/or vertical neglect.     

Symbolic versus associative learning

Ramscar and colleagues (2010, this volume) describe the "feature-label-order" (FLO) effect on category learning and characterize it as a constraint on symbolic learning. I argue that FLO is neither a constraint on symbolic learning in the sense of "learning elements of a symbol system" (instead, it is an effect on nonsymbolic, association learning) nor is it, more than any other constraint on category learning, a constraint on symbolic learning in the sense of "solving the symbol grounding problem."     

Questioning Chase and Simon's (1973) “Perception in Chess”: The “experience recognition” hypothesis

Pattern recognition lies at the heart of the cognitive science endeavor. In this paper, we provide some criticism of this notion, using studies of chess as an example. The game of chess is, as significant evidence shows, a game of abstractions: pressures; force; open files and ranks; time; tightness of defense; old strategies rapidly adapted to new situations. These ideas do not arise on current computational models, which apply brute force by rote-memorization. In this paper we assess the computational models of CHREST and CHUMP, and argue that chess chunks must contain semantic information. This argument leads to a new and contrasting claim, as we propose that key conclusions of Chase and Simon's (1973) influential study stemmed from a non-sequitur. In the concluding section, we propose a shift in philosophy, from “pattern recognition” to a framework of “experience recognition”.     

Language access and language selection in professional translators

Two experiments were conducted measuring self-paced reading to study language access and language selection in professional translators and bilinguals when they understood sentences randomly presented in their first language (L1, Spanish) and second language (L2, English). These sentences contained a critical cognate word or a control matched word. The effect of cognate words was considered an index of between-language activation while the inhibition of the non-target language was examined with the asymmetrical switching cost. In Experiment 1, participants read and repeated sentences while in Experiment 2 participants read sentences without repeating them after reading. The results indicated that lexical processing depended on the experience of participants in professional translation and the demands imposed by the understanding task (reading and repeating or only reading).     

To carry or not to carry — Is this the question? Disentangling the carry effect in multi-digit addition

Recent research has suggested addition performance to be determined by both the need for a carry operation and problem size. Nevertheless, it has remained debatable, how these two factors are interrelated. In the current study, this question was pursued by orthogonally manipulating carry and problem size in two-digit addition verification. As the two factors interacted reliably, our results indicate that the carry effect is moderated by number magnitude processing rather than representing a purely procedural, asemantic sequence of processing steps. Moreover, it was found that the carry effect may not be a purely categorical effect but may be driven by continuous characteristics of the sum of the unit digits as well. Since the correct result of a carry problem can only be derived by integrating and updating the magnitudes of tens and units within the place-value structure of the Arabic number system, the present study provides evidence for the idea that decomposed processing of tens and units also transfers to mental arithmetic.     

What is the source of cultural differences? -- Examining the influence of thinking style on the attribution process

The present research is intended to find out whether individuals with analytic or holistic thought have different attribution processes. Cross-cultural research has suggested that East Asians, who tend to have a holistic thought pattern, differ in cognitive process from Westerners, who tend to engage in analytic thought. However, studies that found cultural difference in attribution process may have non-equivalence problems that make it hard to interpret the causal relationship between thinking style and attribution process. The present research extends this by measuring participants’ thinking style within a single culture in order to ensure equivalence on potentially confounding variables such as prior knowledge and cognitive capacity. Two experiments demonstrate that both types of thinkers have identical attribution processes and suggest different thinking styles might relate to different tendencies toward situational information, but not to the attribution process itself.     

A pilot randomized trial of metacognitive therapy vs applied relaxation in the treatment of adults with generalized anxiety disorder

Metacognitive Therapy (MCT) and Applied Relaxation (AR) were compared in a pilot treatment trial of generalized anxiety disorder (GAD). Twenty outpatients meeting criteria for DSM-IV-TR GAD were assessed before treatment, after treatment and at 6 m and 12 m follow-up. The patients were randomized and treated individually for 8-12 weekly sessions. There was no drop-out from MCT and 10% at 6 m follow-up from AR. At post-treatment and at both follow-up points MCT was superior to AR. Standardized recovery rates for MCT at post-treatment were 80% on measures of worry and trait-anxiety compared with 10% following AR. At 6 m follow-up recovery rates for MCT were 70% on both measures compared with 10% and 20% for AR. At 12 m follow-up recovery rates for MCT were 80% (worry) and 60% (trait-anxiety) compared with 10% and 20% following AR. The recovery rates for MCT are similar to those obtained in an earlier uncontrolled trial (Wells & King, 2006). The effect sizes and standardized recovery rates for MCT suggest that it is a highly effective treatment.     

Evaluating the cognitive avoidance model of generalised anxiety disorder: Impact of worry on threat appraisal, perceived control and anxious arousal

Generalised anxiety disorder (GAD) is characterised by persistent and uncontrollable worry. According to the cognitive avoidance theory of GAD, worry may function as an affective dampening strategy motivated by intolerance of negative emotional states. By facilitating avoidance of more distressing cognitions and associated affect, worry is said to preclude modification of the fear representation in memory, maintaining threat associations and perpetuating further anxiety and worry. The present study evaluated these assumptions in a treatment-seeking GAD sample. Sixty-one participants were randomly allocated to conditions in which they were instructed to worry, imaginally process or relax in response to an anxiety trigger. Results supported the detrimental impact of worry, showing maintained threat expectancies and decreased control perceptions compared to other modes of processing. However, skin conductance level increased as a function of worry and there was no suggestion that worry suppressed affective responding. These findings highlight the need for clarification of the mechanisms involved in the maintenance of threat associations and worry in GAD.
