An intelligent facial expression recognition system with emotion intensity classification

Facial expressions play a crucial role in emotion recognition as compared to other modalities. In this work, an integrated network, which is capable of recognizing emotion intensity levels from facial images in real time using deep learning technique is proposed. The cognitive study of facial expressions based on expression intensity levels are useful in applications such as healthcare, coboting, Industry 4.0 etc. This work proposes to augment emotion recognition with 2 other important parameters, valence and emotion intensity. This helps in better automated responses by a machine to an emotion. The valence model helps in classifying emotion as positive and negative emotions and discrete model classifies emotions as happy, anger, disgust, surprise and neutral state using Convolution Neural Network (CNN). Feature extraction and classification are carried out using CMU Multi-PIE database. The proposed architecture achieves 99.1% and 99.11% accuracy for valence model and discrete model respectively for offline image data with 5-fold cross validation. The average accuracy achieved in real time for valance model and discrete model is 95% & 95.6% respectively. Also, this work contributes to build a new database using facial landmarks, with three intensity levels of facial expressions which helps to classify expressions into low, mild and high intensities. The performance is also tested for different classifiers. The proposed integrated system is configured for real time Human Robot Interaction (HRI) applications on a test bed consisting of Raspberry Pi and RPA platform to assess its performance.     

Memory retrieval as a self-propagating process

Retrieval of a subset of studied items and the presentation of those items as retrieval cues typically impair retrieval of the other items. Previous research on this self-limiting property of memory retrieval has relied heavily on short retention intervals and similar context between encoding and test. Here, we examined retrieval dynamics also after a prolonged retention interval with different spatial and social context between encoding and test, conditions that mimic people’s remembering in many situations of daily life. For both unrelated word lists and more integrated prose material, we found retrieval and cuing to impair recall of other studied items after a short retention interval, but to improve recall in the prolonged retention interval condition. The results demonstrate that retrieval dynamics depend critically on situation, indicating that quite often in daily life, retrieval may be a self-propagating, rather than a self-limiting process.     

Context reinstatement and memory for intrinsic versus extrinsic context: The role of item generation at encoding or retrieval

According to many theoretical accounts, reinstating study context at the time of test creates optimal circumstances for item retrieval. The role of context reinstatement was tested in reference to context memory in several experiments. On the encoding phase, participants were presented with words printed in two different font colors (intrinsic context) or two different sides of the computer screen (extrinsic context). At test, the context was reinstated or changed and participants were asked to recognize words and recollect their study context. Moreover, a read‐generate manipulation was introduced at encoding and retrieval, which was intended to influence the relative salience of item and context information. The results showed that context reinstatement had no effect on memory for extrinsic context but affected memory for intrinsic context when the item was generated at encoding and read at test. These results supported the hypothesis that context information is reconstructed at retrieval only when context was poorly encoded at study.     

Not in My Backyard! Authoritarianism,Social Dominance Orientation,and Support for Strict Immigration Policies at Home and Abroad

Many controversial immigration policies have recently emerged across the United States and abroad. We explore the role of national context in shaping support for such policies. Specifically, we examine whether the extent to which ideological attitudes—Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO)—predict policy support is moderated by the national context of the policy. Across three studies, United States citizens read about a controversial immigration policy affecting either their own country (United States) or a foreign country (Israel or Singapore) and indicated their support for the policy. Results reveal that SDO predicts policy support, regardless of its national context; this effect is mediated by perceived competition. Conversely, RWA predicts policy support only if the policy affects domestic immigration; this effect is mediated by perceptions of cultural threat. Consistent with prior research, the present findings highlight the role of perceived cultural threat to one's ingroup and perceived competition in shaping attitudes toward immigration and shed light on some of the motivations underlying the recent rise in popularity of strict immigration policies.     

Stepping Into a Map: Initial Heading Direction Influences Spatial Memory Flexibility

Learning a novel environment involves integrating first‐person perceptual and motoric experiences with developing knowledge about the overall structure of the surroundings. The present experiments provide insights into the parallel development of these egocentric and allocentric memories by intentionally conflicting body‐ and world‐centered frames of reference during learning, and measuring outcomes via online and offline measures. Results of two experiments demonstrate faster learning and increased memory flexibility following route perspective reading (Experiment 1) and virtual navigation (Experiment 2) when participants begin exploring the environment on a northward (vs. any other direction) allocentric heading. We suggest that learning advantages due to aligning body‐centered (left/right/forward/back) with world‐centered (NSEW) reference frames are indicative of three features of spatial memory development and representation. First, memories for egocentric and allocentric information develop in parallel during novel environment learning. Second, cognitive maps have a preferred orientation relative to world‐centered coordinates. Finally, this preferred orientation corresponds to traditional orientation of physical maps (i.e., north is upward), suggesting strong associations between daily perceptual and motor experiences and the manner in which we preferentially represent spatial knowledge.     

Moving Through Time: The Role of Personality in Three Real‐Life Contexts

In English, two deictic space‐time metaphors are in common usage: the Moving Ego metaphor conceptualizes the ego as moving forward through time and the Moving Time metaphor conceptualizes time as moving forward toward the ego (Clark, 1973). Although earlier research investigating the psychological reality of these metaphors has typically examined spatial influences on temporal reasoning (e.g., Boroditsky & Ramscar, 2002), recent lines of research have extended beyond this, providing initial evidence that personality differences and emotional experiences may also influence how people reason about events in time (Duffy & Feist, 2014; Hauser, Carter, & Meier, 2009; Richmond, Wilson, & Zinken, 2012). In this article, we investigate whether these relationships have force in real life. Building on the effects of individual differences in self‐reported conscientiousness and procrastination found by Duffy and Feist (2014), we examined whether, in addition to self‐reported conscientiousness and procrastination, there is a relationship between conscientious and procrastinating behaviors and temporal perspective. We found that participants who adopted the Moving Time perspective were more likely to exhibit conscientious behaviors, while those who adopted the Moving Ego perspective were more likely to procrastinate, suggesting that the earlier effects reach beyond the laboratory.     

Group cohesion and adherence in unstructured exercise groups

ObjectivesPrevious research has reported a positive relationship between perceptions of cohesion and adherence within structured exercise settings. Given that the social determinants of adherence can vary across situations, this study aimed to examine the cohesion–adherence relationship in unstructured exercise settings.DesignThis study employed a cross-sectional design.MethodsYoung adults (N = 125) recalled an unstructured exercise group where they had been participants, and then rated their perceptions of cohesion with respect to that group as well as reported the number of times/month they had been active in that group.ResultsRegression results revealed that cohesion was significantly related to adherence. Individuals who reported higher levels of task and lower levels of social cohesion, with both dimensions of cohesion reflecting the perceptions of the group as a totality, attended more sessions.ConclusionsThese findings extend research reporting that the cohesiveness perceived in a structured exercise group is related to adherence. However, there were two findings that were not consistent with previous research. The failure of the task dimension associated with satisfying personal needs and objectives to emerge as well as the emergence of a negative relationship with one of the social dimensions of cohesion suggest that the relationship between cohesion and adherence may play out differently in an unstructured versus structured setting with young adults.     

Sleep experiences,dissociation, imaginal experiences,and schizotypy: The role of context

Watson (2001) reported moderate correlations between the Iowa Sleep Experience Survey (ISES) and self-report measures of dissociation and schizotypy. Subsequent investigations (Fassler, Knox, & Lynn, 2003; Watson, 2003) reported similar, although somewhat more modest, correlations between the ISES and measures of dissociation and schizotypy, as well as with measures of absorption and negative affect. The present study tested subjects in conditions in which the measures of sleep experiences were administered with other measures in either the same (N = 86) or a different (N = 87) test context. We determined that sleep experiences were associated with measures of dissociation, absorption, and schizotypy. We closely replicated Watson (2001) and found that the ISES correlations with other measures were not affected by the test context. We suggest that Watson’s (2001) hypothesized common domain of unusual cognitive and perceptual experiences (e.g., sleep experiences) may be underpinned by common ties to imaginative experiences.     

Quantum perichoresis: Quantum field theory and the Trinity

The main thesis of this article is that the Trinitarian theological doctrine of perichoresis can be metaphorically interpreted as a form of Divine phase entanglement with the world. Such entanglement would entail non-local, relational holism and superposition through which the immanent unity of the Trinity is economically present in creation. Christ kenoticly empties himself of the immanent perichoresis of the Trinity in order to enter the economic perichoresis of the creation. The Spirit is then the continuing perichoretic love of God sanctifying the creation toward life and fulfillment from within. It is the Trinity in ongoing perichoretic entanglement with the creation, affirming Divine ubiquity and panentheism.     

Repetition priming across distinct contexts: Effects of lexical status,word frequency,and retrieval test

Previous studies have shown an interference of task-irrelevant numerical information with the spatial parameters of visuomotor behaviour. These findings lend support to the notion that number and space share a common metric with respect to action. Here I argue that the demonstration of the structural similarity between scales for number and space would be a more stringent test for the shared metrics than a mere fact of interference. The present study investigated the scale of number mapping onto space in a manual estimation task. The physical size of target stimuli and the magnitudes of task-irrelevant numbers were parametrically manipulated in the context of the Titchener illusion. The results revealed different scaling schemas for number and space. Whereas estimates in response to changes in stimulus physical size showed a gradual increase, the effect of number was categorical with the largest number (9) showing greater manual estimate than the other numbers (1, 3, and 7). Possible interpretations that are not necessarily incompatible with the hypothesis of shared metrics with respect to action are proposed. However, the present findings suggest that a meticulous scale analysis is required in order to determine the nature of number–space interaction.
