Dissociating the representation of action- and sound-related concepts in middle temporal cortex

Modality-specific models of conceptual memory propose close links between concepts and the sensory-motor systems. Neuroimaging studies found, in different subject groups, that action-related and sound-related concepts activated different parts of posterior middle temporal gyrus (pMTG), suggesting a modality-specific representation of conceptual features. However, as these different parts of pMTG are close to each other, it is possible that the observed anatomical difference is merely related to interindividual variability. In the present functional magnetic resonance imaging study, we now investigated within the same participant group a possible conceptual feature-specific organization in pMTG. Participants performed lexical decisions on sound-related (e.g., telephone) and action-related (hammer) words. Sound words elicited higher activity in anterior pMTG adjacent to auditory association cortex, but action-related words did so in posterior pMTG close to motion sensitive areas. These results confirm distinct conceptual representations of sound and action in pMTG, just adjacent to the respective modality-specific cortices.     

When appearance concerns make women look bad: Solo status and body image concerns diminish women’s academic performance

Women entering male-dominated fields often find themselves the only women present, i.e., they experience solo status. Solo status diminishes women’s performance when women are negatively stereotyped in the testing domain (Inzlicht & Ben-Zeev, 2000) or when the performance is public (Sekaquaptewa & Thompson, 2002). Because women experience greater body image concerns than men and underperform when these concerns are high (Fredrickson, Roberts, Noll, Quinn, & Twenge, 1998), body image concerns may also cause diminished performance in solo women. Women were given a stigmatized (i.e., heavy) or neutral appearance (via a manipulated photograph), then tested as either solos or non-solos. Results showed that women performed more poorly when given a stigmatized appearance and placed under solo status compared to when only one of these factors were present. Social identity threat concerns (Steele, Spencer, & Aronson, 2002) mediated the solo status effect on performance for women given a stigmatized appearance.     

How Women’s Nonconscious Association of Sex with Submission Relates to Their Subjective Sexual Arousability and Ability to Reach Orgasm

Common cultural stereotypes promote women’s submission to men, especially within intimate heterosexual relationships. Mirroring these stereotypes, women possess nonconscious associations between sex and submission (Sanchez, Kiefer & Ybarra, 2006). Moreover, women’s sex-submission associations predict greater reports of engagement in submissive sexual behavior (Sanchez et al., 2006). In the present research, we again found that women associate sex with submission at a nonconscious level. Study 1 showed that women’s nonconscious sex-submission associations predict reduced subjective arousability. Study 2 further demonstrated that these associations predict impaired ability to reach orgasm among women. These findings suggest that sex-submission associations may adversely affect women’s sexual functioning.     

Training Parents in Forgiving and Reconciling

Teaching parents how to forgive transgressions of parenting partners may reduce negative emotions, increase positive emotions, and, thus, decrease parenting stress. We implemented a waiting-list design to investigate the efficacy of a 9-hour psychoeducational group intervention, Forgiveness and Reconciliation through Experiencing Empathy (FREE), presented to 27 parents and caregivers of children 0–9 years old. Participants receiving FREE exhibited increased forgiveness of a target offense by the parenting partner and increased forgiveness of all parenting offenses. This study offers initial evidence that an intervention to promote forgiveness and reconciliation in parents could be beneficial and might improve parenting relations.     

Attentional sensitization of unconscious visual processing: Top-down influences on masked priming

Classical theories of automaticity assume that automatic processes elicited by unconscious stimuli are autonomous and independent of higher-level cognitive influences. In contrast to these classical conceptions, we argue that automatic processing depends on attentional amplification of task-congruent processing pathways and propose an attentional sensitization model of unconscious visual processing: According to this model, unconscious visual processing is automatic in the sense that it is initiated without deliberate intention. However, unconscious visual processing is susceptible to attentional top-down control and is only elicited if the cognitive system is configured accordingly. In this article, we describe our attentional sensitization model and review recent evidence demonstrating attentional influences on subliminal priming, a prototypical example of an automatic process. We show that subliminal priming (a) depends on attentional resources, (b) is susceptible to stimulus expectations, (c) is influenced by action intentions, and (d) is modulated by task sets. These data suggest that attention enhances or attenuates unconscious visual processes in congruency with attentional task representations similar to conscious perception. We argue that seemingly paradoxical, hitherto unexplained findings regarding the automaticity of the underlying processes in many cognitive domains can be easily accommodated by our attentional sensitization model. We conclude this review with a discussion of future research questions regar-ding the nature of attentional control of unconscious visual processing.     

Controlling the unconscious: attentional task sets modulate subliminal semantic and visuomotor processes differentially

Are unconscious processes susceptible to attentional influences? In two subliminal priming experiments, we investigated whether task sets differentially modulate the sensitivity of unconscious processing pathways. We developed a novel procedure for masked semantic priming of words (Experiment 1) and masked visuomotor priming of geometrical shapes (Experiment 2). Before presentation of the masked prime, participants performed an induction task in which they attended to either semantic or perceptual object features designed to activate a semantic or perceptual task set, respectively. Behavioral and electrophysiological effects showed that the induction tasks differentially modulated subliminal priming: Semantic priming, which involves access to conceptual meaning, was found after the semantic induction task but not after the perceptual induction task. Visuomotor priming was observed after the perceptual induction task but not after the semantic induction task. These results demonstrate that unconscious cognition is influenced by attentional control. Unconscious processes in perceptual and semantic processing streams are coordinated congruently with higher-level action goals.     

Quantification and analysis of saccadic and smooth pursuit eye movements and fixations to detect oculomotor deficits

Assessment of deficits in oculomotor function may be useful to detect visuomotor impairments due to a closed head injury. Systematic analysis schemes are needed to reliably quantify oculomotor deficits associated with oculomotor impairment via brain trauma. We propose a systematic, automated analysis scheme using various eye-tracking tasks to assess oculomotor function in a cohort of adolescents with acute concussion symptoms and aged-matched healthy controls. From these data we have evidence that these methods reliably detect oculomotor deficits in the concussed group, including reduced spatial accuracy and diminished tracking performance during visually guided prosaccade and self-paced saccade tasks. The accuracy and tracking deficits are consistent with prior studies on oculomotor function, while introducing novel discriminatory measures relative to fixation assessments – methodologically, a less complicated measure of performance – and thus represent a reliable and simple scheme of detection and analysis of oculomotor deficits associated with brain injury.     

Contingencies of self-worth, academic failure, and goal pursuit

Two studies examine the effects of failure on explicit and implicit self-esteem, affect, and self-presentation goals as a function of people's trait self-esteem and academic contingency of self-worth. Study 1 shows that participants with low self-esteem (LSE) who receive failure feedback experience lower state self-esteem, less positive affect, and less desire to be perceived as competent the more they base self-worth on academics. In contrast, participants with high self-esteem (HSE) who strongly base self-worth on academics show a slight boost in state self-esteem and desire to be perceived as competent following failure. Study 2 shows that following failure, academically contingent LSE participants downplay the importance of appearing competent to others and associate themselves with failure on an implicit level. Taken together, these findings suggest that academically contingent HSE people show resilience following failure, whereas academically contingent LSE people experience negative outcomes and disengage from the pursuit of competence self-presentation goals.
