Feeding Feelings: Is There A Relationship Between Emotional Eating And Body Mass Index In Adults?, Peta Stapleton, Eleanor Mackay
Feeding Feelings: Is There A Relationship Between Emotional Eating And Body Mass Index In Adults?, Peta Stapleton, Eleanor Mackay
Peta B. Stapleton
The present study aimed to investigate the relationship between emotional eating and body mass index (BMI) in an international sample of healthy weight, overweight, and obese adults (N = 226). It was hypothesised emotional eating scores would differ significantly between the BMI classification groups. Consistent with expectations, ANCOVA results revealed significant differences in emotional eating scores across weight groups, after controlling for gender. Post-hoc analyses revealed participants who were overweight or obese reported higher emotional eating levels than participants who were normal weight. An analysis of variance indicated that being over the age of 50 was the strongest predictor of …
Probabilistic Atlases For Face And Biological Motion Perception: An Analysis Of Their Reliability And Overlap, Andrew Engell
Probabilistic Atlases For Face And Biological Motion Perception: An Analysis Of Their Reliability And Overlap, Andrew Engell
Andrew Engell
Neuroimaging research has identified several category-selective regions in visual cortex that respond most strongly when viewing an exemplar image from a preferred category, such as faces. Recent studies, however, have suggested a more complex pattern of activation that has been heretofore unrecognized, e.g., the presence of additional patches of activation to faces beyond the well-studied fusiform face area, and the activation of ostensible face selective regions by animate motion of non-biological forms. Here, we characterize the spatial pattern of brain activity evoked by viewing faces or biological motion in large fMRI samples (N > 120). We create probabilistic atlases for both …
Common Neural Mechanisms For The Evaluation Of Facial Trustworthiness And Emotional Expressions As Revealed By Behavioral Adaptation, Andrew Engell
Common Neural Mechanisms For The Evaluation Of Facial Trustworthiness And Emotional Expressions As Revealed By Behavioral Adaptation, Andrew Engell
Andrew Engell
People rapidly and automatically evaluate faces along many social dimensions. Here,we focus on judgments of trustworthiness, which approximate basic valence evaluation of faces, and test whether these judgments are an overgeneralization of the perception of emotional expressions. We used a behavioral adaptation paradigm to investigate whether the previously noted perceptual similarities between trustworthiness and emotional expressions of anger and happiness extend to their underlying neural representations. We found that adapting to angry or happy facial expressions causes trustworthiness evaluations of subsequently rated neutral faces to increase or decrease, respectively. Further, we found no such modulation of trustworthiness evaluations after participants …
Differential Activation Of Frontoparietal Attention Networks By Social And Symbolic Spatial Cues, Andrew Engell
Differential Activation Of Frontoparietal Attention Networks By Social And Symbolic Spatial Cues, Andrew Engell
Andrew Engell
Perception of both gaze-direction and symbolic directional cues (e.g. arrows) orient an observer’s attention toward the indicated location. It is unclear, however, whether these similar behavioral effects are examples of the same attentional phenomenon and, therefore, subserved by the same neural substrate. It has been proposed that gaze, given its evolutionary significance, constitutes a ‘special’ category of spatial cue. As such, it is predicted that the neural systems supporting spatial reorienting will be different for gaze than for non-biological symbols. We tested this prediction using functional magnetic resonance imaging to measure the brain’s response during target localization in which laterally …
The Fmri Bold Signal Tracks Electrophysiological Spectral Perturbations, Not Event-Related Potentials., Andrew Engell
The Fmri Bold Signal Tracks Electrophysiological Spectral Perturbations, Not Event-Related Potentials., Andrew Engell
Andrew Engell
Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are primary tools of the psychological neurosciences. It is therefore important to understand the relationship between hemodynamic and electrophysiological responses. An early study by Huettel and colleagues found that the coupling of fMRI blood-oxygen-level-dependent signal (BOLD) and subdurally-recorded signal-averaged event-related potentials (ERPs) was not consistent across brain regions. Instead, a growing body of evidence now indicates that hemodynamic changes measured by fMRI reflect non-phase-locked changes in high frequency power rather than the phase-locked ERP. Here, we revisit the data from Huettel and colleagues and measure event-related spectral perturbations (ERSPs) to examine the …
Selective Attention Modulates Face-Specific Induced Gamma Oscillations Recorded From Ventral Occipitotemporal Cortex, Andrew Engell
Selective Attention Modulates Face-Specific Induced Gamma Oscillations Recorded From Ventral Occipitotemporal Cortex, Andrew Engell
Andrew Engell
EEG studies from subdural electrodes have demonstrated a face-specific event-related potential (face-N200) recorded from human ventral occipitotemporal cortex. The insensitivity of face-N200 to task manipulations has supported the proposal that face-N200 reflects an initial obligatory response to faces. This result stands in striking contrast to results of neuroimaging studies that have demonstrated strong task sensitivity of the fusiform hemodynamic response evoked by faces, and thus has created a paradox in the face perception literature. We recorded field potentials directly from the cortical surface of 16 patients while they selectively attended to faces or houses. Here we report that face-specific gamma …
Facial Expression And Gaze-Direction In Human Superior Temporal Sulcus, Andrew Engell
Facial Expression And Gaze-Direction In Human Superior Temporal Sulcus, Andrew Engell
Andrew Engell
The perception of facial expression and gaze-direction are important aspects of non-verbal communication. Expressions communicate the internal emotional state of others while gaze-direction offers clues to their attentional focus and future intentions. Cortical regions in the superior temporal sulcus(STS) play a central role in the perception of expression and gaze, but the extent to which the neural representations of these facial gestures are overlapping is unknown. In the current study 12 subjects observed neutral faces with direct-gaze, neutral faces with averted-gaze, or emotionally expressive faces with direct-gaze while we scanned their brains with functional magnetic resonance imaging (fMRI), allowing a …
Implicit Trustworthiness Decisions: Automatic Coding Of Face Properties In Human Amygdala, Andrew Engell
Implicit Trustworthiness Decisions: Automatic Coding Of Face Properties In Human Amygdala, Andrew Engell
Andrew Engell
Deciding whether an unfamiliar person is trustworthy is one of the most important decisions in social environments. We used functional magnetic resonance imaging to show that the amygdala is involved in implicit evaluations of trustworthiness of faces, consistent with prior findings. The amygdala response increased as perceived trustworthiness decreased in a task that did not demand person evaluation. More importantly, we tested whether this response is due to an individual’s idiosyncratic perception or to face properties that are perceived as untrustworthy across individuals. The amygdala response was better predicted by consensus ratings of trustworthiness than by an individual’s own judgments. …

Explaining The Link Between Perfectionism And Self-Forgiveness: The Mediating Roles Of Self-Acceptance And Rumination, Lee Dixon, Katherine Earl, Catherine Lutz-Zois, Jackson Goodnight, Jessica Peatee
Catherine Lutz Zois
Although recent research has begun to examine correlates of self-forgiveness, very little research has examined the association between self-forgiveness and perfectionism. This study examined this association, along with mediating mechanisms that help explain this association. Specifically, we examined the indirect relationships between both Conscientious and Self-Evaluative forms of perfectionism and episodic self-forgiveness, through both unconditional self-acceptance and rumination. Participants (N = 206) completed measures of perfectionism, unconditional self-acceptance, rumination about a specific betrayal they committed, and self-forgiveness of said betrayal. Multivariate path analyses revealed Self-Evaluative Perfectionism to be indirectly associated with self-forgiveness, through both unconditional self-acceptance and rumination. More specifically, …
Do Student Perceptions Of Diversity Emphasis Relate To Learning Of Psychology?, J. Elicker, A. Snell, Allison O'Malley
Do Student Perceptions Of Diversity Emphasis Relate To Learning Of Psychology?, J. Elicker, A. Snell, Allison O'Malley
Alison L. O'Malley
We examined the extent to which students' perceived inclusion of diversity issues in the Introduction to Psychology course related to perceptions of learning. Based on the responses of 625 students, multilevel linear modeling analyses revealed that student perceptions of diversity emphasis in the class were positively related to how well students believed they understood concepts and the extent to which they believed they learned concepts they could apply to their lives. We also examined the relation between individual differences (e.g., age, race) and perceived learning. We discuss the importance of including issues of diversity in psychology classes.
Effect Of Knowledge Of Apoe Genotype On Subjective And Objective Memory Performance In Healthy Older Adults, Tara Lineweaver, Mark Bondi, Douglas Galasko, David Salmon
Effect Of Knowledge Of Apoe Genotype On Subjective And Objective Memory Performance In Healthy Older Adults, Tara Lineweaver, Mark Bondi, Douglas Galasko, David Salmon
Tara T. Lineweaver
Objective—The knowledge that one carries the apolipoprotein E (APOE) ε4 allele risk factor for Alzheimer’s disease was recently found to have little short-term psychological risk. The authors investigated the impact of knowledge of carrying the risk allele on subjective ratings of memory and objective memory test performance of older adults. Method—Using a nested case-control design, the authors administered objective verbal and visual memory tests and self-rating scales of memory function to 144 cognitively normal older adults (ages 52–89) with known APOE genotype who knew (ε4+, N=25; ε4−, N=49) or did not know (ε4+, N=25; ε4−, N=45) their genotype and genetic …

Kinematic Effects In Large Transport Aircraft, Shem Malmquist, Dennis Vincenzi, Dahai Liu
Dahai Liu
The control of an aircraft relies on sensory feedback. It follows that any aspect that could create a situation where that feedback is faulty can lead to unintended outcomes. The size of very large jet aircraft can result in kinematic effects that impact the perceptions of the flight crew. Due to the large amount of inertia involved, coupled with aerodynamic factors, when the aircraft pitch (θ) is initially changed, the short term actual motion of the aircraft, as viewed from the center of gravity, remains relatively unchanged. As a consequence of aircraft design, this results in the flight deck changing …
Mixed-Case Format And Lexical Decision Performance: Initial Uppercase Is Special, Julia Harvey Azzolina, Lois Rotuno, April Butler Waltonen, Albert Smith
Mixed-Case Format And Lexical Decision Performance: Initial Uppercase Is Special, Julia Harvey Azzolina, Lois Rotuno, April Butler Waltonen, Albert Smith
April D Waltonen
Previous research has shown that there are phenomena that may require a route to word identification by means other than through letters. For example, in a lexical decision task, in which an experimental participant is asked to determine if a string of letters is a word or not, responses to items in a MIXed caSE format are slower than to items in PURE UPPERCASE or pure lowercase formats. In this experiment, we investigated the effect of different mixed-case formats on lexical decision performance, focusing on the type and location of the case transition. Twenty-four students participated in a lexical decision …

The Realism Continuum, Representation And Perception, Stuart Medley, Hanadi Haddad
The Realism Continuum, Representation And Perception, Stuart Medley, Hanadi Haddad
Stuart Medley
The realism continuum is a visual model that presents any image as a series of pictures, iteratively reduced in representation from its referrent. A continuum has been used before to gauge the effectiveness of educational instruction (Wileman 1993; Dwyer 1972; Knowlton 1966; Gropper 1963) or to explain the communicative potential of different comics stylings (McCloud 1993). Reference is made in new design theory to less detailed images being easier to scan for pertinent information and generally reducing demand on working memory (Malamed, 2009). None of these theorists explains how it is we can see the less-real-than-real in the first instance, …
Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius
Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius
Gesa Praetorius
Traffic management is not formally organised in the maritime domain. Ships are autonomous and find their own way. Traffic is organised through rules, regulations, and “good seamanship”; it is a distributed system. In areas of high traffic-density support is proved by vessel traffic service (VTS) to promote traffic safety and fluency. VTS does not take control. This organisational structure has proven itself in situations with sufficient resources. When resources become insufficient (e.g. not enough sailing space), the traffic needs an organising mechanism. In this article, the authors argue that the most promising way to do this is by organising centralised …
Emotional Doubt And Divine Hiddenness, A. Thornhill
Emotional Doubt And Divine Hiddenness, A. Thornhill
A. Chadwick Thornhill
This essay will seek to develop a possible model for addressing the existential problem of divine hiddenness and the emotional doubt that it might cause in the life of a believer. In doing so, it will identify several potential "root causes" for the experience of the existential problem of divine hiddenness and attempt to guide a hurting individual through dealing with their doubt by applying misbelief therapy.
Situation Awareness And Maritime Traffic: Having Awareness Or Being In Control?, Fulko Van Westrenen, Gesa Praetorius
Situation Awareness And Maritime Traffic: Having Awareness Or Being In Control?, Fulko Van Westrenen, Gesa Praetorius
Gesa Praetorius
Situation awareness (SA) is generally seen as a mental representation of the system state, an objective measure of the ‘situation out there’. In this article, the authors make an argument that SA can only have a meaning in relation to the task of the user and characteristics of the system. This will be argued with the help of a specific environment: vessel traffic monitoring. The long-time constants and the complex constraints imposed on the ship require that the operator monitoring the traffic has a good SA: the operator must make long-term predictions about possible traffic developments. For this, being in …

Integration Of Speed Signals In The Direction Of Motion, Dawn Vreven, Preeti Verghese
Integration Of Speed Signals In The Direction Of Motion, Dawn Vreven, Preeti Verghese
Dawn L Vreven
Speed discrimination tasks were used to examine the spatial and temporal characteristics of the integration mechanism involved when signals are extended in the direction of motion. We varied the aspect ratio of a signal patch whose speed differed from the background, while holding the area of the signal patch constant, so that the signal patch could be either extended in the direction of motion or extended orthogonal to the direction of motion. Speed discrimination thresholds decreased dramatically as the signal patch was extended in the direction of motion. The spatial and temporal integration regions were larger than would be expected …

Detecting Structure In Glass Patterns: An Interocular Transfer Study, Dawn Vreven, Jarrod Berge
Dawn L Vreven
Glass patterns are visual stimuli used here to study how local orientation signals are spatially integrated into global pattern perception. We measured a form aftereffect from adaptation to both static and dynamic Glass patterns and calculated the amount of interocular transfer to determine the binocularity of the detectors responsible for the perception of global structure. Both static and dynamic adaptation produced significant form aftereffects and showed a very high degree of interocular transfer, suggesting that Glass-pattern perception involves cortical processing beyond primary visual cortex. Surprisingly, dynamic adaptation produced significantly greater interocular transfer than static adaptation. Our results suggest a functional …
The Absence Of Depth Constancy In Contour Stereograms, Dawn Vreven, Leslie Welch
The Absence Of Depth Constancy In Contour Stereograms, Dawn Vreven, Leslie Welch
Dawn L Vreven
Stereoscopic surfaces constructed from Kanizsa-type illusory contours or explicit luminance contours were tested for three-dimensional (3-D) shape constancy. The curvature of the contours and the apparent viewing distance between the surface and the observer were manipulated. Observers judged which of two surfaces appeared more curved. Experiment 1 allowed eye movements and revealed a bias in 3-D shape judgment with changes in apparent viewing distance, such that surfaces presented far from the observer appeared less curved than surfaces presented close to the observer. The lack of depth constancy was approximately the same for illusory-contour surfaces and for explicit-contour surfaces. Experiment 2 …
Mindscapes And Landscapes: Hayek And Simon On Cognitive Extension, Leslie Marsh
Mindscapes And Landscapes: Hayek And Simon On Cognitive Extension, Leslie Marsh
Leslie Marsh
Hayek’s and Simon’s social externalism runs on a shared presupposition: mind is constrained in its computational capacity to detect, harvest, and assimilate “data” generated by the infinitely fine-grained and perpetually dynamic characteristic of experience in complex social environments. For Hayek, mind and sociality are co-evolved spontaneous orders, allowing little or no prospect of comprehensive explanation, trapped in a hermeneutically sealed, i.e. inescapably context bound, eco-system. For Simon, it is the simplicity of mind that is the bottleneck, overwhelmed by the ambient complexity of the environmental. Since on Simon’s account complexity is unidirectional, Simon is far more ebullient about the prospects …
