Identifying bilingual semantic neural representations across languages

The goal of the study was to identify the neural representation of a noun’s meaning in one language based on the neural representation of that same noun in another language. Machine learning methods were used to train classifiers to identify which individual noun bilingual participants were thinking about in one language based solely on their brain activation in the other language. The study shows reliable (p < .05) pattern-based classification accuracies for the classification of brain activity for nouns across languages. It also shows that the stable voxels used to classify the brain activation were located in areas associated with encoding information about semantic dimensions of the words in the study. The identification of the semantic trace of individual nouns from the pattern of cortical activity demonstrates the existence of a multi-voxel pattern of activation across the cortex for a single noun common to both languages in bilinguals.     

Illusory contour figures are perceived as occluding contours by 4-month-old infants

Although 4-month-olds perceive continuity of an object's trajectory through occlusion, little is known about the information specifying an occluding surface at this age. We investigated this in 3 experiments involving 84 participants. Testing the claim that 5-month-olds are unable to perceive the Kanizsa figure as an occluding surface (Csibra, 2001), we demonstrated that 4-month-olds perceived trajectory continuity behind this figure providing its horizontal extent was small. We demonstrated that the presence of visible occluding edges or occlusion of background was insufficient to specify an occluding surface but that their combination was sufficient. Thus, beyond object deletion and accretion, both visible occluding edges and occlusion of background are necessary for perception of occluding surfaces at this age.     

Young infants' perception of the trajectories of two- and three-dimensional objects

We investigated oculomotor anticipations in 4-month-old infants as they viewed center-occluded object trajectories. In two experiments, we examined performance in two-dimensional (2D) and three-dimensional (3D) dynamic occlusion displays and in an additional 3D condition with a smiley face as the moving target stimulus. Rates of anticipatory eye movements were not facilitated by 3D displays or by the (presumably) more salient smiley face relative to the 2D condition. However, latencies of anticipations were reduced, implying that 3D visual information may have supported formation of more robust mental representations of the moving object. Results are interpreted in a context of perceptual constraints on developing cognitive capacities during early infancy.     

Understanding age-related reductions in visual working memory capacity: Examining the stages of change detection

Visual working memory (VWM) capacity is reduced in older adults. Research has shown age-related impairments to VWM encoding, but aging is likely to affect multiple stages of VWM. In the present study, we recorded the event-related potentials (ERPs) of younger and older adults during VWM maintenance and retrieval. We measured encoding-stage processing with the P1 component, maintenance-stage processing with the contralateral delay activity (CDA), and retrieval-stage processing by comparing the activity for old and new items (old–new effect). Older adults showed lower behavioral capacity estimates (K) than did younger adults, but surprisingly, their P1 components and CDAs were comparable to those of younger adults. This remarkable dissociation between neural activity and behavior in the older adults indicated that the P1 and CDA did not accurately assess their VWM capacity. However, the neural activity evoked during VWM retrieval yielded results that helped clarify the age-related differences. During retrieval, younger adults showed early old–new effects in frontal and occipital areas and a late central–parietal old–new effect, whereas older adults showed a late right-lateralized parietal old–new effect. The younger adults’ early old–new effects strongly resembled an index of perceptual fluency, suggesting that perceptual implicit memory was activated. The activation of implicit memory could have facilitated the younger adults’ behavior, and the lack of these early effects in older adults may suggest that they have much lower-resolution memory than do younger adults. From these data, we speculated that younger and older adults store the same number of items in VWM, but that younger adults store a higher-resolution representation than do older adults.     

An Ecological Model of Professional School Counseling

The 21st century has witnessed a drastic transformation in professional school counseling, fueled by calls for social justice and educational equity and characterized by a movement toward collaboration, advocacy, leadership, and systemic change to promote academic success for all students. The authors describe how this transformation is aligned with an ecological perspective, provide an overview of the basic tenets of ecological thinking, and take a first step toward developing an intentional model of ecological school counseling.     

Psychometric Properties of the Minnesota Multiphasic Personality Inventory–Adolescent (MMPI–A) Clinical,Content, and Supplementary Scales in a Forensic Sample

In this study, we evaluated the internal psychometric properties and external correlates of scores on the Clinical, Content, and Supplementary scales in a forensic sample of 496 adolescents (315 boys and 181 girls) who were court-ordered to receive psychological evaluations. We examined Cronbach's alpha coefficients, scale intercorrelation matrices, and frequencies of scale elevations. Further, we found varying degrees of support for the convergent and discriminant validity of scores on the MMPI–A (Butcher et al., 1992 Butcher, J. N., Williams, C. L., Graham, J. R., Archer, R. P., Tellegen, A., Ben-Porath, Y. S. and Kaemmer, B. 1992. MMPI–A (Minnesota Multiphasic Personality Inventory–Adolescent): Manual for administration, scoring, and interpretation, Minneapolis: University of Minnesota Press.  [Google Scholar]) Clinical, Content, and Supplementary scales. This study adds to the body of literature establishing the utility of the MMPI–A in forensic evaluations.     

Talking about sex after cancer: A discourse analytic study of health care professional accounts of sexual communication with patients

There is consistent evidence that health care professionals (hcps) are not addressing the sexual information and support needs of people with cancer. Thirty-eight Australian hcps across a range of professions working in cancer care were interviewed, to examine constructions of sexuality post-cancer, the subject positions adopted in relation to sexual communication, and the ways in which discourses and subject positions shape information provision and communication about sexuality. Participants constructed sexual changes post-cancer in physical, psychological and relational terms, and positioned such changes as having the potential to significantly impact on patient and partner well-being. This was associated with widespread adoption of a discourse of psychosocial support, which legitimated discussion of sexual changes within a clinical consultation, to alleviate distress, dispel myths and facilitate renegotiation of sexual practices. However, this did not necessarily translate into patient-centred practice outcomes, with the majority of participants positioning personal, patient-centred and situational factors as barriers to the discussion of sex within many clinical consultations. This included: absence of knowledge, confidence and comfort; positioning sex as irrelevant or inappropriate for some people; and limitations of the clinical context. In contrast, those who did routinely discuss sexuality adopted a subject position of agency, responsibility and confidence.     

Look into my eyes: Gaze direction and person memory

The current research considered the effects of gaze direction on a fundamental aspect of social cogition: person memory. It was anticipated that a person's direction of gaze (i.e., direct or averted) would impact his or her subsequent memorability, such that recognition would be enhanced for targets previously displaying direct gaze. In Experiment 1, participants were presented with faces displaying either direct or averted gaze in a person‐classification (i.e., conceptual) task. Then, in a surprise memory test, they were required to report whether a presented face had been seen before. As expected, a recognition advantage was observed for targets displaying direct gaze during the initial classification task. This finding was replicated and extended in a second experiment in which participants initially reported the spatial location (i.e., perceptual task) of each face. We consider the implications of these findings for basic aspects of social‐cognitive functioning and person perception.     

Internal reasons and practical limits on rational deliberation

I argue that agent-causal libertarianism has a strong initial rejoinder to Mele's luck argument against it, but that his claim that it has yet to be explained how agent-causation yields responsibility-conferring control has significant force. I suggest an avenue of response. Subsequently, I raise objections to Mele's criticisms of my four-case manipulation argument against compatibilism.
