The Effect of Valence and Arousal on Spatial Attention

Conceptual metaphor theory suggests that to mentally represent abstract concepts we use metaphorical associations to map them onto more concrete constructs (Lakoff & Johnson, 1980; 1999). Using a choice reaction time (CRT) task, Meier and Robinson (2004) found that positively valenced words primed attention to higher areas in vertical space, while negatively valenced words primed attention to lower areas in vertical space, consistent with the good is up/bad is down conceptual metaphor. Meier and Robinson (2004; 2005) suggest this provides evidence that emotional words create an automatic and obligatory metaphor-congruent shift in spatial attention, driven by a Valence x Position interaction. However, other research shows that the arousal level, not just the valence of emotional words can affect reaction time (Robinson, Storbeck, Meier & Kirkeby, 2004). This means concluding that valence alone is driving the shift in attention is premature. Furthermore, Brookshire, Irvy and Casasanto (2010) dispute Meier and Robinson’s claim that the relationship between affect and metaphor is automatic, instead suggesting that affect-metaphor associations are optional and only accessed under certain contextual conditions. The purpose of this thesis was therefore two-fold. First, it aimed to explore whether valence, arousal, or an interaction between the two was responsible for driving the metaphor-consistent shift in spatial attention observed by Meier and Robinson (2004). Second, it aimed to progress the discussion about when affective stimuli, in the form of emotional words, automatically activate the good is up/bad is down conceptual metaphor. Three CRT experiments were conducted in which (a) emotional stimulus words were differentiated by arousal level as well as valence and (b) the evaluation of stimulus words’ affective tone (pleasant/unpleasant) was manipulated. A Valence x Position interaction in relation to the good is up but not bad is down conceptual metaphor was found when the valence of priming words was evaluated, suggesting valence, rather than arousal or a combination of both, is driving the affect-metaphor relationship. No evidence for the automatic activation of affect-metaphor associations was found when the word’s affective tone was not evaluated. These findings suggest that while driven by valence, affect-metaphor associations are not fully automatic and occur only under certain contextual conditions. The implications for our understanding of how emotion impacts spatial attention are discussed, suggesting metaphors enrich, rather than monopolise our mental representation of abstract, affective concepts

Distal posterior tibial artery perforator flaps for the management of calcaneal and Achilles tendon injuries in diabetic and non-diabetic patients

Management of Achilles tendon and heel area defects is a common challenge for the reconstructive surgeon due to the lack of soft tissue availability in that region. In this article, we present our experience in covering these defects by using the distal perforator propeller flaps based on the posterior tibial artery. Perforator flaps are based on cutaneous, small diameter vessels that originate from a main pedicle and perforate the fascia or muscle to reach the skin. Their development has followed the understanding of the blood supply from a source artery to the skin. Six patients (five males and one female) underwent reconstruction by using the posterior tibial artery distal perforator flap for covering defects in the distal Achilles tendon region in patients with and without diabetes mellitus. Postoperative complications included a hypertrophic scar formation in one patient, partial marginal flap necrosis in another patient, and a wound infection in a third patient. All wounds were eventually healed by the last postoperative visit. In conclusion, perforator flaps based on the distal posterior tibial artery may be a reliable option for the coverage of small to moderate size defects of the Achilles tendon and heel area regions

Vulvar reconstruction should be performed using gluteal-fold perforator flap because of less morbidities and complication

The autors present a case of bilateral vulvar defects after abrasion of malignant skin neoplasm, reconstructed with a gluteal-fold perforator flap, resulting in a successful outcome

Understanding adaptation to first episode psychosis through the creation of images

This article aims to understand and explore the meaning of adaptation to First Episode Psychosis (FEP). An innovative method of data collection was used with ten participants who experienced FEP which integrated drawings of their lived experience within semi-structured interviews. The data were analysed through Interpretative Phenomenological Analysis and hermeneutic-phenomenological image analysis. Participants’ experience was captured in four superordinate themes which identified that adaptation to FEP entailed: ‘Finding out how psychosis fits into my story’, ‘Breaking free from psychosis’, ‘Fighting my way through psychosis’, and ‘Finding a new way of being ‘me’’. The participants’ path of adaptation to FEP was an interplay of pains, challenges, and gains, and there was resonance with posttraumatic growth in their accounts. This article illustrates that creating images may offer a powerful way of conveying the multifaceted aspects of adaptation to FEP and could help individuals in communicating and processing their experience
