An inner face advantage in children's recognition of familiar peers

Children’s recognition of familiar own-age peers was investigated. Chinese children (4-, 8-, and 14-year-olds) were asked to identify their classmates from photographs showing the entire face, the internal facial features only, the external facial features only, or the eyes, nose, or mouth only. Participants from all age groups were familiar with the faces used as stimuli for 1 academic year. The results showed that children from all age groups demonstrated an advantage for recognition of the internal facial features relative to their recognition of the external facial features. Thus, previous observations of a shift in reliance from external to internal facial features can be attributed to experience with faces rather than to age-related changes in face processing.     

Mood trajectories following daily life events

Little is known about the magnitude and duration of mood responses to daily negative events as a function of gender, history of mood disorder, and current substance use. Using computerized ambulatory monitoring techniques, perceived negativity of minor daily events and state affect were prospectively examined every 3 h on average for a 7-day period. Event negativity was associated with depressed mood for 6–9 h following event occurrence, and was associated with happy mood for 3–6 h. Gender and substance use moderated the relationship between event negativity and mood states concurrently, and remained influential for approximately 3 h following the event. History of mood disorder did not moderate any within- or across-day relationships between event negativity and mood. No evidence was found for mood uplifts following daily events in either within- or across-day analyses. The findings are discussed relative to assessment timing in investigations of vulnerability-stress theories.     

Hippocampal low-frequency stimulation and chronic mild stress similarly disrupt fear extinction memory in rats

Disruptions of fear extinction-related potentiation of synaptic efficacy in the connection between the hippocampus (HPC) and the medial prefrontal cortex (mPFC) have been shown to impair the recall of extinction memory. This study was undertaken to examine if chronic mild stress (CMS), which is known to alter induction of HPC–mPFC long-term potentiation, would also interfere with both extinction-related HPC–mPFC potentiation and extinction memory. Following fear conditioning (5 tone-shock pairings), rats were submitted to fear extinction (20 tone-alone presentations), which produced an increase in the amplitude of HPC–mPFC field potentials. HPC low-frequency stimulation (LFS), applied immediately after training, suppressed these changes and induced fear return during the retention test (5 tone-alone presentations). CMS, delivered before fear conditioning, did not interfere with fear extinction but blocked the development of extinction-related potentiation in the HPC–mPFC pathway and impaired the recall of extinction. These findings suggest that HPC LFS may provoke metaplastic changes in HPC outputs that may mimic alterations associated with a history of chronic stress.     

On the (mis)categorization of unattractive brides and attractive prostitutes: extending evaluative congruency effects to social category activation

Numerous studies have shown that social categorization is a flexible process that partly depends on contextual variables. However, little is known about the role of affect in people's access to categorical dimensions. We investigated the hypothesis that social category activation is facilitated on evaluatively congruent dimensions. Two studies provide support for this evaluative-matching hypothesis, in which social categorization was found to be faster and more accurate for evaluatively congruent categories (i.e., unattractive foreigners, unattractive prostitutes, attractive fellow-citizens and attractive brides) than for evaluatively incongruent categories (i.e., attractive foreigners, attractive prostitutes, unattractive fellow-citizens and unattractive brides). We discuss the theoretical and practical implications of these findings.     

Liking products by the head of a dog: Perceived orientation of attention induces valence acquisition

We show that the valence acquired by an object is sensitive to the perceived attention it receives and that this effect occurs in a quite implicit fashion. Participants were exposed to products (i.e., peppermint brands) associated with the head of dogs oriented toward them, looking straight ahead, or oriented away from them. Participants then completed an affective priming task, which allowed us to assess the valence acquired by the products in a task free of desirability concerns. Results show that the valence of the products increased linearly as the perceived orientation of attention of the targets moved toward them. This finding suggests that mimetic desire effects may be activated in a quite implicit fashion. The theoretical and social implications of this finding are discussed.     

Holistic processing is tuned for in-group faces

Past research has found that mere in-group/out-group categorizations are sufficient to elicit biases in face memory. The current research yields novel evidence that mere social categorization is also sufficient to modulate processes underlying face perception, even for faces for which we have strong perceptual expertise: same-race (SR) faces. Using the composite face paradigm, we find that SR faces categorized as in-group members (i.e., fellow university students) are processed more holistically than are SR faces categorized as out-group members (i.e., students at another university). Hence, holding perceptual expertise with faces constant, categorizing an SR target as an out-group member debilitates the strong holistic processing typically observed for SR faces.     

An exploration of the moderating effect of trait emotional intelligence on memory and attention in neutral and stressful conditions

Trait emotional intelligence (trait EI) refers to individual differences in the experience, perception, regulation, and utilization of emotions. Research has shown that trait EI moderated subjective and endocrine responses to both natural and laboratory stressors. This study explores, the cognitive processes underlying this effect, under the hypothesis that trait EI moderates the impact of stress on memory and/or attention. Results supported the hypothesis, but solely for the ‘regulation’ EI‐dimension (named self‐control or SC). In neutral conditions, high SC was characterized by an attentional focus to neutral material and a facilitated memory for positive events, whereas low SC was characterized by an attentional focus to emotional material (regardless of valence) and a facilitated memory for negative events. In stressful conditions, high SC individuals engaged attention to emotional material (regardless of valence) and recalled more negative events, while low SC individuals disengaged attention from emotional material and recalled more positive events.     

Unintended embodiment of concepts into percepts: Sensory activation boosts attention for same-modality concepts in the attentional blink paradigm

This study shows that sensory priming facilitates reports of same-modality concepts in an attentional blink paradigm. Participants had to detect and report two target words (T1 and T2) presented for 53 ms each among a series of nonwords distractors at a frequency of up to 19 items per second. SOA between target words was set to 53 ms or 213 ms, with reduced attention expected for T2 under the longer SOA (attentional blink) and for T1 under the shorter SOA (lag-1 sparing). These effects were found but reduced when the sensory modality of the concepts matched that of a sensory stimulation occurring prior to the detection trial. Hence, sensory activation increased report for same-modality concepts. This finding reveals that grounded cognition effects (1) are involved in conceptual processing as soon as a word has reached the point of lexical identification and (2) occur independent of intentional access to sensory properties of concepts.     

Actuality and possibility: On the complementarity of two registers in the bodily constitution of experience

The purpose of this paper is to demonstrate the usefulness of the concept of possibility, and not merely that of actuality, for an inquiry into the bodily constitution of experience. The paper will study how the possibilities of action that may (or may not) be available to the subject help to shape the meaning attributed to perceived objects and to the situation occupied by the subject within her environment. This view will be supported by reference to empirical evidence provided by recent and current research on the perceptual estimation of distances and the effects brought about by the use of a tool on the organisation of our perceived immediate space.
