Not all triads are created equal: further support for the importance of visual and semantic proximity in object identification

Identification deficits were investigated in ELM, a temporal lobe stroke patient with category-specific deficits. We replicated previous work done on FS, a patient with category specific deficits as a result of herpes viral encephalitis. ELM was tested using novel, computer generated shapes that were paired with artifact labels. We paired semantically close or disparate labels to shapes and ELM attempted to learn these pairings. Overall, ELM's shape-label confusions were most detrimentally affected when we used labels that referred to objects that were visually and semantically close. However, as with FS, ELM had as many errors when shapes were paired with the labels "donut," "tire," and "washer" as he did when they were paired with visually and semantically close artifact labels. Two explanations are put forth to account for the anomalous performance by both patients on the triad of donut-tire-washer.     

Automatic integration of non-perceptual action effect features: the case of the associative affective Simon effect

In the first phase of Experiment 1, participants were instructed to move a response key up or down in response to a go signal. One of both responses was consistently followed by an aversive stimulus, whereas the other response was never followed by the aversive stimulus. In a subsequent test phase, the same responses had to be emitted according to the grammatical category (noun or adjective) of positive and negative target words. Results showed that the level of affective correspondence between the task-irrelevant positive or negative connotation of the target and the motivational significance of the effect of the correct response influenced performance. The results of Experiment 2 replicated those of Experiment 1, using alternating target-response assignment. These findings point to the integration of affective action effect feature codes in the cognitive representation of actions.     

Attention to primes modulates affective priming of pronunciation responses

In studies on affective priming of pronunciation responses, two words are presented on each trial and participants are asked to read the second word out loud. Whereas some studies revealed shorter reaction times when the two words had the same valence than when they had a different valence, other studies either found no effect of affective congruence or revealed a reversed effect. In the present experiments, a significant effect of affective congruence only emerged when filler trials were presented in which the prime and target were identical and participants were instructed to attend to the primes (Experiment 2). No effects were found when participants were merely instructed to attend to or ignore the primes (Experiment 1), or when affectively incongruent filler trials were presented and participants were instructed to ignore the primes (Experiment 2).     

Adapting to Context in Community-Based Participatory Research: “Participatory Starting Points” in a Chinese Immigrant Worker Community

Community-based participatory research (CBPR) is increasingly being used to better understand and improve the health of diverse communities. A key strength of this research orientation is its adaptability to community contexts and characteristics. To date, however, few studies explicitly discuss adaptations made to CBPR principles and processes in response to community context and partners’ needs. Using data from our CBPR study, the San Francisco Chinatown Restaurant Worker Health and Safety Project, and drawing from literature on immigrant political incorporation, we examine the links between the contexts of the Chinese immigrant worker community, adaptations made by our collaborative, and study outcomes. In particular, we explore the concepts of contexts of reception and participatory starting points, which may be especially relevant for partnerships with immigrant communities whose members have historically had lower rates of civic and political participation in the US. We discuss contextual findings such as worker partner accounts of language barriers, economic and social marginalization, and civic skills and participation, as well as subsequent adaptations made by the partnership. We also describe the relative effectiveness of these adaptations in yielding equitable participation and building partners’ capacity. We conclude by sharing lessons learned and their implications for CBPR and partnerships with immigrant communities more broadly.     

Complexity of referrals to a specialist psychotherapy service

Consecutive referrals to a specialist psychotherapy service were analysed for complexity. Some 71% had a severe enduring mental illness or personality disorder. Two-thirds of the rest had added psychosocial or behavioural complexity. Only 9% had no severe enduring mental illness, personality disorder, or added complexity; nearly half of these had somatoform disorder. Only 2% of the patients had uncomplicated depression or anxiety disorders.

Patients treated in this psychotherapy service are substantially different from those on whom NICE bases its guidance for the treatment of depression and anxiety, and for whom IAPT was conceived, it functions as a de facto complex case service.     

The organisation of emotional experience: Creating links among emotion,thinking, language,and intentional action

Abstract

This paper discusses how emotional experience is interpreted, understood, and represented. Changes in the status of valued goals, and whether or not these goals can be attained or maintained are key conditions in determining the occurrence of an emotional experience. In addition, assessing the certainty with which goals can be maintained is critical as to which emotion is experienced. This small set of dimensions can be used to identify, and differentiate emotions that are considered to be basic. Basic emotion categories share features, and their elicitation is contingent on a number of components coming into conjunction with one another simultaneously. Thus, for any one basic emotion to be elicited, at least three converging components need to be activated. This view of the conditions for emotion is discussed with reference to componential theories of emotion, and to its developmental and cross-cultural implications.     

Blinking predicts enhanced cognitive control

Recent models have suggested an important role for neuromodulation in explaining trial-to-trial adaptations in cognitive control. The adaptation-by-binding model (Verguts & Notebaert, Psychological review, 115(2), 518–525, 2008), for instance, suggests that increased cognitive control in response to conflict (e.g., incongruent flanker stimulus) is the result of stronger binding of stimulus, action, and context representations, mediated by neuromodulators like dopamine (DA) and/or norepinephrine (NE). We presented a flanker task and used the Gratton effect (smaller congruency effect following incongruent trials) as an index of cognitive control. We investigated the Gratton effect in relation to eye blinks (DA related) and pupil dilation (NE related). The results for pupil dilation were not unequivocal, but eye blinks clearly modulated the Gratton effect: The Gratton effect was enhanced after a blink trial, relative to after a no-blink trial, even when controlling for correlated variables. The latter suggests an important role for DA in cognitive control on a trial-to-trial basis.
