The appeal of the devil’s eye: social evaluation affects social attention

Humans typically exhibit a tendency to follow the gaze of conspecifics, a social attention behaviour known as gaze cueing. Here, we addressed whether episodically learned social knowledge about the behaviours performed by the individual bearing the gaze can influence this phenomenon. In a learning phase, different faces were systematically associated with either positive or negative behaviours. The same faces were then used as stimuli in a gaze-cueing task. The results showed that faces associated with antisocial norm-violating behaviours triggered stronger gaze-cueing effects as compared to faces associated with sociable behaviours. Importantly, this was especially evident for participants who perceived the presented norm-violating behaviours as far more negative as compared to positive behaviours. These findings suggest that reflexive attentional responses can be affected by our appraisal of the valence of the behaviours of individuals around us.     

An evaluation of the Italian version of the Fagerström Test for Nicotine Dependence

This study examined the psychometric properties of an Italian version of the Fagerstr?m Test for Nicotine Dependence in a sample of 593 smokers who were enrolled in a randomized Phase IV clinical trial to compare bupropion to placebo. This version was administered at baseline, and from each participant an expired air carbon monoxide (CO) measure was taken. Spearman correlations between the Total score and CO concentration were .27 in the combined sample and .27 and .25 among men and women. With respect to the internal consistency reliability, the coefficient alpha was low (alpha= .55) in the combined sample and among men (.59) and women (.50). While the Total score predicted abstinence at 7 wk., it was not significantly related to continuous abstinence at 12 mo. postrandomization. The properties of the Italian version of the Fagerstr?m Test for Nicotine Dependence appear to be consistent with other versions described in the literature.     

Grasp preparation improves change detection for congruent objects

A series of experiments provided converging support for the hypothesis that action preparation biases selective attention to action-congruent object features. When visual transients are masked in so-called change-blindness scenes, viewers are blind to substantial changes between 2 otherwise identical pictures that flick back and forth. The authors report data in which participants planned a grasp prior to the onset of a change-blindness scene in which 1 of 12 objects changed identity. Change blindness was substantially reduced for grasp-congruent objects (e.g., planning a whole-hand grasp reduced change blindness to a changing apple). A series of follow-up experiments ruled out an alternative explanation that this reduction had resulted from a labeling or strategizing of responses and provided converging support that the effect genuinely arose from grasp planning.     

Processing abstract language modulates motor system activity

Embodiment theory proposes that neural systems for perception and action are also engaged during language comprehension. Previous neuroimaging and neurophysiological studies have only been able to demonstrate modulation of action systems during comprehension of concrete language. We provide neurophysiological evidence for modulation of motor system activity during the comprehension of both concrete and abstract language. In Experiment 1, when the described direction of object transfer or information transfer (e.g., away from the reader to another) matched the literal direction of a hand movement used to make a response, speed of responding was faster than when the two directions mismatched (an action-sentence compatibility effect). In Experiment 2, we used single-pulse transcranial magnetic stimulation to study changes in the corticospinal motor pathways to hand muscles while reading the same sentences. Relative to sentences that do not describe transfer, there is greater modulation of activity in the hand muscles when reading sentences describing transfer of both concrete objects and abstract information. These findings are discussed in relation to the human mirror neuron system.     

Chinese Short Form of the Personal Attributes Questionnaire: Construct and Concurrent Validity

This paper evaluated the construct and concurrent validity of a Chinese short form of the Personal Attributes Questionnaire, which measures instrumentality and expressivity as independent traits. In Study 1, 293 Hong Kong Chinese undergraduates completed the scale. Factor analysis revealed two independent factors, instrumentality and expressivity. In Study 2, 269 Hong Kong Chinese undergraduates completed the scale together with the dominance and nurturance scales of the Personality Research Form and Gudykunst’s Self-Construal Scale. Exploratory factor analysis replicated the bidimensional structure of the scale. Instrumentality correlated with independent self-construal and dominance, whereas expressivity correlated with interdependent self-construal and nurturance. Gender differences in item scores overall conformed to theoretical expectations. The findings indicate that the scale produces valid and reliable scores.     

Grasping language – A short story on embodiment

The new concept of embodied cognition theories has been enthusiastically studied by the cognitive sciences, by as well as such disparate disciplines as philosophy, anthropology, neuroscience, and robotics. Embodiment theory provides the framework for ongoing discussions on the linkage between “low” cognitive processes as perception and “high” cognition as language processing and comprehension, respectively. This review gives an overview along the lines of argumentation in the ongoing debate on the embodiment of language and employs an ALE meta-analysis to illustrate and weigh previous findings. The collected evidence on the somatotopic activation of motor areas, abstract and concrete word processing, as well as from reported patient and timing studies emphasizes the important role of sensorimotor areas in language processing and supports the hypothesis that the motor system is activated during language comprehension.
