Attentional biases using the body in the crowd task: Are angry body postures detected more rapidly?

Research using schematic faces has consistently demonstrated attentional biases towards threatening information (angry faces), which are accentuated for individuals with higher levels of anxiety. However, research has yet to reveal whether this is the case for other nonverbal channels of communication. In the research reported here, ninety-five undergraduates completed a body in the crowd task analogous to the face in the crowd task, to examine whether attentional biases for threat existed for schematic body postures. Participants demonstrated faster detection of threat. A discrepant angry posture in a neutral crowd was identified quicker than a discrepant happy posture in a neutral crowd. This effect was pronounced for individuals with higher self-reported levels of trait anxiety. Results also demonstrated evidence of delayed disengagement from threat. Individuals were slower (i.e., more distracted) by identical crowds of angry postures rather than happy or neutral crowds and were slower to detect a discrepant neutral posture among an angry crowd than neutral among a happy crowd. These findings are the first to establish threat biases using body postures in a visual search paradigm. The results are in accordance with previous research using schematic face stimuli. Theoretical and practical implications are discussed.     

Addendum to: Heterogeneity Coefficients for Mahalanobis' D as a Multivariate Effect Size

In a previous paper (Del Giudice, 2017 [Heterogeneity coefficients for Mahalanobis' D as a multivariate effect size. Multivariate Behavioral Research, 52, 216–221]), I proposed two heterogeneity coefficients for Mahalanobis' D based on the Gini coefficient, labeled H and EPV. In this addendum I discuss the limitations of the original approach and note that the proposed indices may overestimate heterogeneity under certain conditions. I then describe two revised indices H₂ and EPV₂, and illustrate the difference between the original and revised indices with some real-world data sets.     

Size does matter: Women mentally rotate large objects faster than men

Performance in a computerized “mental rotation” task was measured in groups of males and females while they rotated Shepard‐Metzler‐like cube assemblies on either a standard laptop screen (size = 36 cm) or on a large display wall (584 cm) where the stimuli appeared at considerably larger sizes and within a much wider field of view than that typically used in most spatial tasks. Males and females did not differ significantly in performance in the standard size condition with regards to response time but females performed faster than males in the large display condition. Males were also found to be significantly more accurate than females, regardless of display. We found no sign of trading accuracy for speed for either of the sexes or screen size conditions. We surmise that such an effect may be due to differences in task‐solving strategies between the sexes, where a holistic strategy – which may be preferred by males is negatively affected by large object sizes, whereas a piecemeal approach, that may be preferred by females, is virtually unaffected by display size.     

Visions as ‘Good to Think’: A Cognitive Approach to Visionary Experience in Islamic Sufi Thought

This article explores one type of visionary experience described and interpreted by mystics within certain traditions, which may be termed a ‘cognitive’ or ‘gnostic’ vision. Such visions provide information or offer solutions to problems of theology or religious interpretation.

A close textual analysis of a selection from the writings of an eighteenth century Indian Sufi, Shāh Wal? Allāh of Delhi, demonstrates this process of intensive thinking through superimposed grids which combine elements of religious symbol systems. This type of thinking triggers a mystical experience which is subsequently interpreted in a problem solving or divinatory mode.     

Moved to tears: Technical considerations and dilemmas encountered in working with a 13-year-old boy with acquired quadriplegia 1

This paper is about therapeutic work with David, a 13-year-old boy who, at the age of 5, was the victim of a hit-and-run road traffic accident resulting in quadriplegia. The circumstances leading to the accident and its sequelae reveal a particularly complex picture, which combines early emotional deprivation and trauma. Although cognitively intact and able to speak, David could not move. Yet he created movement in others through a desperate necessity, by communicating via the employment of extreme projective forces. The highly complex presentation of emotional, psychic and bodily damage in the child, and in particular, David's physical paralysis, has had a profound impact upon what I have come to think of as the ‘mindbody’ of the therapist. Winnicott has talked of the infant's ‘psyche/soma’. Here I want to extend the notion and consider the bodily impact of projections in particular and how these have a powerful emotional and physical resonance on the ‘mindbody’ of the therapist, especially in therapy with a young person whose body is damaged. In this paper, I consider technical challenges and dilemmas encountered in the work, including the complex interplay of transference/countertransference phenomena. This unusual presentation of a boy in extraordinary circumstances led to considerations of psychoanalytic method and interpretative activity, which may be viewed as being inspired by ‘emotional truthfulness’.2 2 Alex Dubinskey (Chair ACP conference 2004) commenting on aspects of this work used the term ‘emotional truthfulness’.

Dans cet article, l'auteur raconte son travail thérapeutique auprès de David, âgé de 13 ans, qui à l'âge de 5 ans fut victime d'un accident de la circulation avec délit de fuite, accident qui le laissa tétraplégique. Les circonstances qui aboutirent à l'accident et à ses séquelles forment un tableau particulièrement complexe mettant en jeu des carences affectives précoces et des traumatismes. Bien que ses capacités cognitives ne fussent nullement atteintes et qu'il fut capable de parler, David ne pouvait pas bouger. Par l'urgence désespérée de son discours, transmise grâce à des projections extrêmement puissantes, il réussissait à susciter du mouvement chez ses interlocuteurs. La présence conjointe et extrêmement complexe de dommages affectifs, psychiques et corporels chez cet enfant – et notamment sa paralysie physique – eut un impact profond sur ce que l'auteur en vient à appeler l'“ esprit-corps ” du psychothérapeute. D. W. Winnicott a parlé du “ psyché-soma ” du jeune enfant. Dans son texte, l'auteur élargit cette notion, notamment pour prendre en considération l'impact corporel des projections, ainsi que leur résonance émotionnelle et physique massive sur l'“ esprit-corps ” du thérapeute, surtout lorsque son patient est une personne jeune dont le corps est endommagé. L'auteur explore les défis et dilemmes techniques rencontrés au cours de son travail, y compris le jeu complexe de phénomènes transférentiels et contre-transférentiels. Ce traitement, inhabituel, avec un garçon dans des circonstances sortant de l'extraordinaire soulève des questions concernant la méthodologie psychanalytique et l'activité interprétative, questions qui peuvent être considérées comme étant inspirées par la “ véracité émotionnelle ”.

Dieser Artikel ist über die therapeutische Arbeit mit David, einem 13-jährigen Jungen, der im Alter von 5 Jahren das Opfer eines Unfalls mit Fahrerflucht war, der zu einer Querschnittslähmung führte. Die Umstände, die zu dem Unfall führten und seine Folgen legen ein besonders komplexes Bild dar, das frühe Vernachlässigung und Trauma kombiniert. Obwohl David kognitiv intakt war und sprechen konnte, konnte er sich nicht bewegen. Doch schaffte er Bewegung aus verzweifelter Notwendigkeit in anderen, indem er mit mithilfe der Benutzung von extremen projektiven Kräften kommunizierte. Die höchst komplexe Präsentation von emotionalem, psychischem und körpelichem Schaden in dem Kind und insbesondere Davids körperliche Lähmung, hatte eine tiefe Auswirkung auf das, was ich nun den ‘mindbody’ (Gemütskörper) des Therapeuten nenne. Winnicott sprach vom Psyche/Soma des Babies. Hier möchte ich diesen Begriff ausweiten und besonders die köperliche Auswirkung der Projektionen betrachten und wie diese eine starke emotionale und physische Resonanz auf den ‘mindbody’ des Therapeutens haben, insbesondere in der Therapie mit einer jungen Person, deren Körper beschädigt ist. In diesem Artikel betrachte ich technische Herausforderungen und Dilemmas, denen man in dieser Arbeit begegnet, einschliesslich der komplexen Wechselwirkung von Übertragungs/ Gegenübertragungsphänomenen. Diese ungewöhnliche Behandlung mit einem Jungen in aussergewöhnlichen Umständen führten zu Überlegungen zur psychoanalytischen Methode undzur Deutungsaktivität, die von ‘emotionaler Wahrheit’ inspiriert wird

Riassunto: In questo articolo si parla del lavoro terapeutico con David, un bambino di 13 anni che, all'età di 5 anni, fu vittima di un incidente stradale che portò alla quadriplegia. Le circostanze che portarono all'incidente e la sua sequela rivelano un quadro particolarmente complesso, nel quale emerge un misto di deprivazione emotiva precoce e trauma. Sebbene David fosse abile cognitivamente e potesse parlare, egli non poteva muoversi. Eppure il bambino generava movimento negli altri attraverso una disperata necessità, comunicando con l'uso di estreme forze proiettive. Il presentarsi di un danno nel bambino altamente complesso nella sua dimensione emotiva, psichica e corporea, ed in particolare, la paralisi fisica di David, hanno avuto un profondo impatto su ciò che ho iniziato a pensare come il ‘corpomente’ del terapeuta. Winnicott ha parlato dello ‘psiche/soma’ del neonato. L'autrice vuole nell'articolo estendere la nozione e considerare l'impatto corporeo delle proiezioni e come queste abbiano una risonanza emotiva e fisica molto forte sul ‘corpomente’ del terapeuta, soprattutto nella terapia con un ragazzo giovane il cui corpo è stato danneggiato. Nell'articolo considero le sfide tecniche e i dilemmi incontrati nel lavoro, compreso il gioco complesso dei fenomeni transferali e controtransferali. Il trattamento insolito con questo bambino in circostanze molto particolari ha portato a considerazioni riguardo al metodo psicoanalitico e all'attività interpretativa, che si possono considerare come ispirati da ‘verità emotiva'¹     

Posture affects emotional responses: A Head Down Bed Rest and ERP study

Body posture, mainly represented by horizontal bed rest, has been found to be associated with cortical inhibition, altered perceptual and cognitive processing. In the present research, the influence of Head Down Bed Rest (HDBR) – a condition also termed simulated microgravity – on emotional responses has been studied. Twenty-two male subjects were randomly assigned to either Sitting Control or HDBR group. After 3-h, subjects attended to a passive viewing emotional task in which 75 IAPS slides, divided into 25 pleasant, 25 neutral and 25 unpleasant, were presented in random order for 6 s each, while EEG was recorded from F7, F8 and Pz locations. Results showed in Sitting Controls the expected greater P300 and Late Positive Potential (LPP) to pleasant and unpleasant compared with neutral slides, an effect which indicates greater processing of emotional arousing stimuli. The HDBR group showed smaller non-significant differences among all emotional conditions in both ERP components. Arousal and valence subjective evaluations, typically less sensitive to experimental manipulation, did not differentiate groups. The observed ability of HDBR to inhibit cortical emotional responses raises an important issue on the risk that astronauts underestimate a dangerous/threatening situation or that long-term bedridden inpatients develop depressive symptoms.     

Dynamic Simulation and Static Matching for Action Prediction: Evidence From Body Part Priming

Accurately predicting other people's actions may involve two processes: internal real‐time simulation (dynamic updating) and matching recently perceived action images (static matching). Using a priming of body parts, this study aimed to differentiate the two processes. Specifically, participants played a motion‐controlled video game with either their arms or legs. They then observed arm movements of a point‐light actor, which were briefly occluded from view, followed by a static test pose. Participants judged whether this test pose depicted a coherent continuation of the previously seen action (i.e., “action prediction task”). Evidence of dynamic updating was obtained after compatible effector priming (i.e., arms), whereas incompatible effector priming (i.e., legs) indicated static matching. Together, the results support action prediction as engaging two distinct processes, dynamic simulation and static matching, and indicate that their relative contributions depend on contextual factors like compatibility of body parts involved in performed and observed action.     

Prototypicality of responses of autistic,language disordered,and normal children in a word fluency task

This article describes an example of making pediatric neuropsychological assessments more time-efficient. Empirical support, including new data, for the utilization of an eight-subtest short form of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991) is reviewed. It is concluded that this short form of the WISC-III is a valid substitute for the complete version under most clinical circumstances, allowing the practitioner to expand on interview, history or more specific neuropsychological tests without adding financial or time burdens to the evaluation.     

Log-normal nanograin-size distributions in nanostructured composites

A key challenge in the fabrication of superhard nanocomposite films is how to control the distribution of grain sizes in these materials. High-resolution transmission electron microscopy has been used to measure nanograin-size distributions in the Ti–B–N films with various B contents. The results show that the mean grain size decreases with increase of B content and the grain-size distribution conforms to a log-normal function when the hardness approaches a maximum value. The transition from normal to log-normal distributions can be determined by analysis in terms of a minimum information criterion. The origin of a log-normal size distribution probably results from heterogeneity arising from a diffusion-drift process.     

Effect of cooling rate on size-dependent atomic ordering of CoPt nanoparticles

We report on the effect of cooling rate on the size-dependent atomic ordering of CoPt nanoparticles using aberration corrected high-resolution transmission electron microscopy. It was found that cooling rate plays a crucial role in promoting atomic ordering during the cooling process after annealing. Nanoparticles of ≈3?nm in diameter show the A1-disordered phase after annealing at 873?K for 1?h followed by rapid cooling (110?K/min), while the L1₀-ordered phase is obtained when the cooling rate is slow (1.5?K/min). The disordered phase is also obtained by rapid cooling after annealing at 973?K for 1?h. These results unambiguously indicate that the order–disorder transformation temperature is reduced to a temperature at least lower than 873?K for CoPt nanoparticles smaller than 3?nm in diameter. The slow cooling process promotes the atomic ordering, which resulted in an enhancement of magnetic coercivity as high as 2200?Oe. This study demonstrates that hard magnetic properties of the CoPt nanoparticles can be improved by controlling the cooling rate after heat treatments.
