Face to face with emotion: holistic face processing is modulated by emotional state

Negative emotions are linked with a local, rather than global, visual processing style, which may preferentially facilitate feature-based, relative to holistic, processing mechanisms. Because faces are typically processed holistically, and because social contexts are prime elicitors of emotions, we examined whether negative emotions decrease holistic processing of faces. We induced positive, negative, or neutral emotions via film clips and measured holistic processing before and after the induction: participants made judgements about cued parts of chimeric faces, and holistic processing was indexed by the interference caused by task-irrelevant face parts. Emotional state significantly modulated face-processing style, with the negative emotion induction leading to decreased holistic processing. Furthermore, self-reported change in emotional state correlated with changes in holistic processing. These results contrast with general assumptions that holistic processing of faces is automatic and immune to outside influences, and they illustrate emotion's power to modulate socially relevant aspects of visual perception.     

A visual short-term memory advantage for faces

What determines how much can be stored in visual short-term memory (VSTM)? Studies of VSTM have focused largely on stimulus-based properties such as the number or complexity of the items stored. Recent work also suggests that capacity is severely reduced for items within the same category. However, the importance for VSTM capacity of more qualitative differences in processing for different categories has not been investigated. For example, faces are processed more holistically than other objects. In Experiments 1 and 2, we show that the processing of faces, objects that are crucial socially and for which we possess considerable expertise, overcomes these limitations. More faces can be stored in VSTM than objects from other complex nonface categories. As in prior studies, at short encoding durations we found that capacity for faces was less than that for other categories. However, at longer encoding durations, capacity for faces exceeded that for nonface objects, and this advantage was specific to upright faces. Because inversion reduces holistic processing, the interaction of orientation with VSTM capacity—which occurred for faces but not objects in Experiment 3—suggests that it is holistic processing that confers an advantage for face VSTM when sufficient encoding time is allowed.     

A Mixed‐Method Examination of Preschool Teacher Beliefs About Social–Emotional Learning and Relations to Observed Emotional Support

The connections between parents' socialization practices and beliefs about emotions, and children's emotional development have been well studied; however, teachers' impacts on children's social–emotional learning (SEL) remain widely understudied. In the present study, private preschool and Head Start teachers (N = 32) were observed using the Classroom Assessment Scoring System. Comparison groups were created based on their observed emotional support and then compared on their qualitative responses in focus group discussions on beliefs about emotions and SEL strategies. Teachers acknowledged the importance of preparing children emotionally (as well as academically) for kindergarten, but substantial differences emerged between the highly emotionally supportive and moderately emotionally supportive teachers in three areas: (1) teachers' beliefs about emotions and the value of SEL; (2) teachers' socialization behaviours and SEL strategies; and (3) teachers' perceptions of their roles as emotion socializers. Understanding such differences can facilitate the development of intervention programs and in‐service training to help teachers better meet students' SEL needs.

Effects of A Parenting-Focused Mindfulness Intervention on Adolescent Substance Use and Psychopathology: A Randomized Controlled Trial

Substance use and psychopathology symptoms increase in adolescence. One key risk factor for these is high parent stress. Mindfulness interventions reduce stress in adults and may be useful to reduce parent stress and prevent substance use (SU) and psychopathology in adolescents. This study tested the feasibility and effects of a mindfulness intervention for parents on adolescent SU and psychopathology symptoms. Ninety-six mothers of 11–17 year olds were randomly assigned to a mindfulness intervention for parents (the Parenting Mindfully [PM] intervention) or a brief parent education [PE] control group. At pre-intervention, post-intervention, 6-month follow-up, and 1-year follow-up, adolescents reported on SU and mothers and adolescents reported on adolescent externalizing and internalizing symptoms. Primary intent to treat analyses found that the PM intervention prevented increases in adolescent SU over time, relative to the PE control group. The PM intervention also prevented increases in mother-reported externalizing symptoms over time relative to the PE control group. However, PM did not have a significant effect on internalizing symptoms. PM had an indirect effect on adolescent-reported externalizing symptoms through greater mother mindfulness levels at post-intervention, suggesting mother mindfulness as a potential intervention mechanism. Notably, while mothers reported high satisfaction with PM, intervention attendance was low (31% of mothers attended zero sessions). Secondary analyses with mothers who attended?>??=?50% of the interventions (n?=?48) found significant PM effects on externalizing symptoms, but not SU. Overall, findings support mindfulness training for parents as a promising intervention and future studies should work to promote accessibility for stressed parents.

Individual differences in FFA activity suggest independent processing at different spatial scales

The brain processes images at different spatial scales, but it is unclear how far into the visual stream different scales remain segregated. Using functional magnetic resonance imaging, we found evidence that BOLD activity in the fusiform face area (FFA) reflects computations based on separate spatial frequency inputs. When subjects perform different tasks (attend location vs. identity; attend whole vs. parts) or the same task with different stimuli (upright or inverted) with high- and low-pass images of cars and faces, individual differences in the FFA in one condition are correlated with those in the other condition. However, FFA activity in response to low-pass stimuli is independent of its response to highpass stimuli. These results suggest that spatial scales are not integrated before the FFA and that processing in this area could support the flexible use of different sources of information present in broad-pass images.     

Enhanced visual short-term memory in action video game players

Visual short-term memory (VSTM) is critical for acquiring visual knowledge and shows marked individual variability. Previous work has illustrated a VSTM advantage among action video game players (Boot et al. Acta Psychologica 129:387–398, 2008). A growing body of literature has suggested that action video game playing can bolster visual cognitive abilities in a domain-general manner, including abilities related to visual attention and the speed of processing, providing some potential bases for this VSTM advantage. In the present study, we investigated the VSTM advantage among video game players and assessed whether enhanced processing speed can account for this advantage. Experiment 1, using simple colored stimuli, revealed that action video game players demonstrate a similar VSTM advantage over nongamers, regardless of whether they are given limited or ample time to encode items into memory. Experiment 2, using complex shapes as the stimuli to increase the processing demands of the task, replicated this VSTM advantage, irrespective of encoding duration. These findings are inconsistent with a speed-of-processing account of this advantage. An alternative, attentional account, grounded in the existing literature on the visuo-cognitive consequences of video game play, is discussed.     

Disentangling Fine Motor Skills’ Relations to Academic Achievement: The Relative Contributions of Visual-Spatial Integration and Visual-Motor Coordination

Recent research has established a connection between children's fine motor skills and their academic performance. Previous research has focused on fine motor skills measured prior to elementary school, while the present sample included children ages 5–18 years old, making it possible to examine whether this link remains relevant throughout childhood and adolescence. Furthermore, the majority of research linking fine motor skills and academic achievement has not determined which specific components of fine motor skill are driving this relation. The few studies that have looked at associations of separate fine motor tasks with achievement suggest that copying tasks that tap visual-spatial integration skills are most closely related to achievement. The present study examined two separate elements of fine motor skills—visual-motor coordination and visual-spatial integration—and their associations with various measures of academic achievement. Visual-motor coordination was measured using tracing tasks, while visual-spatial integration was measured using copy-a-figure tasks. After controlling for gender, socioeconomic status, IQ, and visual-motor coordination, and visual-spatial integration explained significant variance in children's math and written expression achievement. Knowing that visual-spatial integration skills are associated with these two achievement domains suggests potential avenues for targeted math and writing interventions for children of all ages.
