- Abstract/Description
-
The perception and interpretation of faces provides individuals with a wealth of knowledge that enables them to navigate their social environments more successfully. Prior research has hypothesized that the decreased facial expression recognition (FER) abilities observed in autism spectrum disorder (ASD) may be better explained by comorbid alexithymia, the alexithymia hypothesis. The present study sought to further examine the alexithymia hypothesis by collecting data from 59 participants and...
Show moreThe perception and interpretation of faces provides individuals with a wealth of knowledge that enables them to navigate their social environments more successfully. Prior research has hypothesized that the decreased facial expression recognition (FER) abilities observed in autism spectrum disorder (ASD) may be better explained by comorbid alexithymia, the alexithymia hypothesis. The present study sought to further examine the alexithymia hypothesis by collecting data from 59 participants and examining FER performance and eye movement patterns for ASD and neurotypical (NT) individuals while controlling for alexithymia severity. Eye movement-related differences and similarities were examined via eye tracking in conjunction with statistical and machine-learning-based pattern classification analysis. In multiple different classifying conditions, where the classifier was fed 1,718 scanpath images (either at spatial, spatial-temporal, or spatial temporal-ordinal levels) for high-alexithymic ASD, high-alexithymicvi NT, low-alexithymic ASD, and low-alexithymic NT, we could accurately decode significantly above chance level. Additionally, in the cross-decoding analysis where the classifier was fed 1,718 scanpath images for high- and low alexithymic ASD individuals and tested on high- and low-alexithymic NT individuals, results showed that classification accuracy was significantly above chance level when using spatial images of eye movement patterns. Regarding FER performance results, we found that ASD and NT groups performed similarly, but at lower intensities of expressions, ASD individuals performed significantly worse than NT individuals. Together, these findings suggest that there may be eye-movement related differences between ASD and NT individuals, which may interact with alexithymia traits.

Show moreSocial influence is sought to distribute information processing for decision-making when data is limited. Undergraduate students selected information with normative or informational wording to supplement a fabricated academic integrity appeal from their university and decided whether to affirm the charge. A novel measure, the Adaptive Scale of Preference for Normative Versus Informational Social Influence (ASPNVISI), was piloted in comparison with a Polish scale of influence preference, individual difference measures in motivation (e.g., Need for Closure), and behavioral measures of influence-seeking. Results did not support the hypotheses that psychological needs would predict behavioral social influence preferences, though Need for Cognition and Need to Belong predicted self-reported preferences. The ASPNVISI was correlated with the existing scale of influence preference, providing support for its continued development. Contrary to the hypothesis, confidence in the decision on a charge of academic dishonesty was not related to selected influence; race and conservatism were related to confidence, and gender to the selections. Next steps include further pilot testing of the ASPNVISI and expansion of the behavioral task.

Show moreMemes have become a staple in political communication. However, the relationship between individuals’ political orientation, their level of affective polarization, the moral content of memes, and meme effectiveness is underexplored. I expected that polarized partisans would rate ingroup memes as more effective than outgroup memes. In line with moral foundations theory, I expected that polarized liberals would rate individualizing foundation memes as more effective than less polarized memes and that polarized conservatives would rate binding foundation memes as more effective than less polarized conservatives. Participants (N = 467) rated moral political memes for meme effectiveness. Results indicated that more polarized conservatives, but not liberals, rated ingroup memes as more effective than outgroup memes. Polarized liberals rated purity/sanctity as more effective than less polarized liberals. Polarized conservatives rated fairness/reciprocity plus the binding foundations memes as more effective than less polarized conservatives. These results indicate that polarized partisans react to memes differently.

Show moreCognitive flexibility is crucial for efficient goal-directed behavior, especially in rapidly changing environments. While recent studies have consistently shown enhanced theta power and synchronization in the frontoparietal network during flexible task-switching, direct evidence establishing a causal link between theta-rhythm brain oscillation and cognitive flexibility remains limited. In this study, we applied transcranial alternating current stimulation (tACS) to the frontoparietal network at a theta frequency (6 Hz) with a phase difference of either 0° (inphase) or 180° (antiphase) to explore its impact on task-switching performance. The results showed no significant tACS modulation effects on switch costs or neural oscillatory synchronization in the frontoparietal network. However, a consistent negative correlation was observed between frontoparietal theta power in the early time window of cue-target interval and task switching performance, implying the close relationship between proactive control in task switching and frontoparietal theta activities.

Show moreInfants have an innate desire to form social bonds and jealousy protests are an attempt to regain exclusive maternal attention from a social usurper. The current study examined neurophysiological and bio-hormonal processes related to jealousy responses during the first year and a half of life. Prior to and after the first year of life, infants express jealousy protest behavior when faced with a social threat. Resting-state frontal EEG coherence indicated a developmental shift from bilateral connectivity in younger infants to increased frontal specialization in older infants in relation to jealousy responses. Furthermore, 6- to 9-month-old infants exhibited more frontal neuroconnectivity in the right hemisphere (i.e., an area related to negative emotions) of the brain compared to left when faced with social threat. Lastly, social threat activated HPA reactivity in infants higher in temperamental distress. This study provides further evidence for the emerging links between physiological and socioemotional responses in infancy due to loss of exclusive maternal attention.

Specifically, this study aims to explore the effect of consumers receiving the same negative attribute twice versus two different negative attributes for a product. The introduction of this study will discuss background concepts like the Controlled Semantic Cognition Framework from Lambon Ralph et al., (2017) and the neural processes behind selection as discussed in Thompson-Schill et al., (1997). The results indicated that there were differences in hemodynamic response between conditions where the same negative attribute was presented with a product twice versus conditions where two different negative attributes were presented with a product. Both behaviorally and hemodynamically, the results provide evidence supporting an inner conflict when dealing with two negative alternative choices. Future research could include realistic advertisements to better mimic everyday scenarios.

Show morePrior research on neurophysiology of infants of depressed mothers commonly has focused on EEG power and asymmetry. Whether infants of depressed mothers show differences in coherence is undetermined. This study examined the development of EEG alpha coherence in infants of mothers with various degrees of depression. Also investigated was the normative development of alpha coherence in infancy. The relationship between maternal depression and infant coherence was analyzed at different infant ages, from 1-12-months-old. There were significant effects of maternal depression on infant coherence between frontal-occipital regions, frontal-parietal regions, and central-parietal regions, in 1-month-olds. There were also significant maternal depression effects in central-parietal coherence in 1-3-month-olds and 3-6-month-olds. Differences were in the right hemisphere and were generally characterized by lower coherence in infants whose mothers had higher depression. Infants whose mothers had lower depression demonstrated age-related decreases in coherence, but infants of more highly depressed mothers did not show age-related differences.

Show moreWhile the thalamus and hippocampus are generally understood to contribute to mammalian spatial navigation, the degree to which thalamic input contributes to representations of space during navigation remains unclear. Specifically, anterior dorsal thalamic nuclei (ADN) provide a relational or directional framework known as the head direction (HD) network, which is hypothesized to play a significant role in guiding hippocampal-dependent navigation. The current study focuses on the contribution of the ADN to direction and place-dependent spatial navigation in adult male C57BL6J mice. An inhibitory chemogenetic (hM4Di) receptor was bilaterally expressed in the ADN after viral stereotaxic injection. Mice were trained in a spatially focused task, the Morris water maze (MWM), and after systemic administration of the hM4Di agonist, clozapine-Noxide (CNO) at 5mg/kg, demonstrated equivalent preference for using directional or place-based search behavior. These results suggest that the selective silencing of ADN at 5mg/kg CNO does not negatively affect spatial navigation in mice.

Justice is conceptualized through the lens of two opposing frames: consistency and compensatory. Participants assigned positive or negative outcomes to one of two hypothetical people, one person being depicted as “lucky”, the other as “unlucky.” A consistency sense of justice views justice as keeping the order of the world (positive with lucky), whereas a compensatory sense of justice understands it as a balancing act (positive with unlucky). ANOVA’s were ran and a single significant difference was found. In one condition, those whose had a consistency sense of justice had a significantly more internal locus of control than those who had a compensatory sense of justice. Further research will be needed to clarify why this difference did not emerge for all allocations.

Show moreRecent success of mindfulness-based interventions in adult and clinical populations, as well as in classroom settings, has spurred the need for a more thorough understanding of mindfulness as a trait that can affect early development of self-regulatory characteristics. The current study used previously collected data on 4th and 5th graders to explore the relationships between trait mindfulness, self-regulation, and stress reactivity, measured using cortisol levels. Self-regulation was measured using effortful control (attention, inhibitory control, and activation control), conscientiousness, agreeableness, negative emotion regulation, and openness to experience. Cortisol findings were significant for negative emotion regulation. Results revealed several significant positive associations between trait mindfulness and several self-regulatory characteristics among people who did and did not respond to a stressor. Further research is necessary to tease apart the unique contribution of individual self-regulatory characteristics, including trait mindfulness, on stress reactivity.

Show moreLearning to effectively execute goal-directed tasks generally requires guidance from knowledgeable experts that can direct the performer’s attention toward important environmental features. However, specifying the optimal attentional strategies is difficult due to the subjective nature of perceptions and the complexity of the underlying neural processes. The current skill acquisition literature emphasizes action-based contingencies through Predictive and Ecological models when examining attentional processes, while Perceptual Control Theory advocates for perceptual-based mechanisms. To evaluate the efficacy of these models, this study implicitly primed one hundred fifteen participants to focus on action-based or perceptual-based aspects during an interceptive task. It was predicted that the perceptual-based priming condition would result in faster learning and greater resilience to environmental disturbances. However, the highly variable results did not show significant differences in learning rate or resilience between the action and perceptual-based conditions. Ultimately, the variability in the findings suggests that a superior performance depends on numerous factors unique to each performer. Consequently, instructional methods cannot rely on a single optimal attentional strategy for gathering environmental information. Instead, the dynamic interplay between the individual and the environment must be considered to foster the skill development of novice performers.

Behavioral data and hemodynamic responses were measured using functional near-infrared spectroscopy (fNIRS) in 38 participants during a study task, where brand-name products and product specific attributes were processed, and during a test phase, where participants chose to purchase either new or previously processed products that were presented with either the same attribute, a different attribute, or no attribute. Results at test showed that repeating the association produced the highest accuracy in selecting the previously processed product and the highest hemodynamic activation. In contrast, presenting a different attribute at test produced the lowest accuracy and least hemodynamic activation, much like baseline. This hemodynamic difference between the same and different conditions was especially prevalent in the left hemisphere during the later time windows. These findings suggest that repeating the association biases purchase intention and produces hemodynamic repetition enhancement. In contrast, changing the association leads to interference and reduced selection of the processed product.

Show moreA hypothesized model of spindle organization of thalamic and hippocampal spike dynamics (Figure 1) suggests that sparsity operates in spindles as an essential component of thalamic activity that could be contributing to flexibility in learning (Varela & Wilson, 2020). We asked the question of whether sparse spindle-like (10Hz non-rhythmic) or 10Hz rhythmic activity in thalamic cells of the reuniens nucleus influence cognitive flexibility during learning after sleep. By comparing the two stimulation protocols (“nonrhythmic” and “rhythmic”), we tested if disrupting the characteristic sparsity reveals any changes in flexibility during learning after sleep. Results showed that sleep accompanied 10Hz rhythmic optogenetic stimulation of thalamic nucleus reuniens impaired rule-switching (or set-shifting) performance and disrupted the sleep enhancing rule-switch associated increase in vicarious trial and error (VTE), which we used as a metric for deliberation. We found that rule-switching was associated with a subsequent increase in VTE, as were incorrect choices, and when rats subsequently made correct choices. Instead, stimulating against the endogenous thalamocortical spindle oscillation (i.e. sleep accompanied 10Hz rhythmic optogenetic stimulation) resulted in a significant disruption in post-sleep performance and VTE during, but not prior to, rule-switching. Lastly, optogenetic 10Hz stimulation of the thalamic nucleus reuniens did not affect sleeping or waking behavior during the sleep box session but it did show a clear though nonsignificant increase in waking head velocities; thus, changes in cognitive flexibility and VTE cannot be explained by any changes in sleep itself, but rather due to the after-effects the specific patterns of 10Hz optogenetic stimulation in thalamic nucleus reuniens applied during sleep had on cognition.

Show moreThe current study examined how viewing an event from different perspectives (eye-level and elevated) at both encoding and retrieval changes the recognition of that event. Specifically, participants were shown various manipulations to the scenarios that they witnessed at encoding. The primary focus of the study was the participants’ ability to identify old scenarios along with scenarios that had been manipulated through differences in character clothing, object placement, or temporal order of events, while still resembling the old scenario in every other way. No support was found to support the prediction that perspective at either encoding or retrieval had an effect on recognition of the scenario or the different manipulation types. An exploratory analysis revealed a trend towards significance for perspective at encoding. An eye-level perspective at encoding was more likely to result in a higher rejection rate for temporal manipulations.

Show moreLearning to read is a fundamental skill that is understudied among children who hear more than one language at home. A particular limitation in the extant literature is that the samples are often Spanish-dominant and come from low-income households. This literature has evidence that Spanish skills – both language-specific (i.e., vocabulary) and language-general (i.e., phonological processing) – predict English reading ability. In the current study, we investigated the effect of oral language skills in both English and Spanish, as well as other pre-literacy skills, on the English reading skill of Spanish-English bilinguals who are English dominant and received English only instruction from school entry. The oral language skills and other pre-literacy skills of 101 Spanish-English dual language learners were assessed at 5 years. English reading skill was measured annually from 6 to 10 years. Latent growth curve analysis was used to model initial English reading skill at 6 years and the growth of English reading skill from 6 to 10 years. Four sets of hypothesized foundational skills measured at child age 5 years were tested as predictors of subsequent English reading skill: (1) English oral language skills, (2) Spanish oral language skills, (3) English and Spanish oral language skills, and (4) English and Spanish oral language skills, with other pre-literacy skills. The results of structural equation modeling indicated that English vocabulary and phonological awareness measured in Spanish were significant predictors when English and Spanish skills were entered separately. When English and Spanish oral language skills were included together, Spanish oral language skills did not explain English reading growth better than when oral language skills were modeled independently. The best model of predictors of English reading for bilingual 5-year-olds included only English vocabulary and English letter recognition.

The ability to recognize human actions is essential for individuals to navigate through their daily life. Biological motion is the primary mechanism people use to recognize actions quickly and efficiently, but their precision can vary. The development of Artificial Neural Networks (ANNs) has the potential to enhance the efficiency and effectiveness of accomplishing common human tasks, including action recognition.

Show moreThe ability to recognize human actions is essential for individuals to navigate through their daily life. Biological motion is the primary mechanism people use to recognize actions quickly and efficiently, but their precision can vary. The development of Artificial Neural Networks (ANNs) has the potential to enhance the efficiency and effectiveness of accomplishing common human tasks, including action recognition. However, the performance of ANNs in action recognition depends on the type of model used. This study aimed to improve the accuracy of ANNs in action classification by incorporating biological motion information into the input conditions. The study used the UCF Crime dataset, a dataset containing surveillance videos of normal and criminal activity, and extracted biological motion information with OpenPose, a pose estimation ANN. OpenPose adjusted to create four condition types using the biological motion information (image-only, image with biological motion, only biological motion, and coordinates only) and used either a 3-Dimensional Convolutional Neural Network (3D CNN) or a Gated Recurrent Unit (GRU) to classify the actions. Overall, the study found that including biological motion information in the input conditions led to higher accuracy regardless of the number of action categories in the dataset. Moreover, the GRU model using the 'coordinates only' condition had the best accuracy out of all the action classification models. These findings suggest that incorporating biological motion into input conditions and using numerical format input data can benefit the development of accurate action classification models using ANNs.

- LONGITUDINAL PREDICTORS OF POPULARITY AND UNPOPULARITY IN MIDDLE CHILDHOOD AND EARLY ADOLESCENCE.

- Altman, Robert L., Laursen, Brett, Florida Atlantic University, Department of Psychology, Charles E. Schmidt College of Science
- Abstract/Description
-
As children enter middle childhood, they become increasing focused on navigating the peer system, which provides an acute awareness of the social hierarchy and their place in it (Gottman & Mettetal, 1986; Parker & Gottman, 1989). Some children even prioritize attaining social status over maintaining friendships (LaFontana & Cillessen, 2010). Status matters because it describes an individual’s ability to compete for and control both physical and social resources (Hawley, 1999). Previous...
Show moreAs children enter middle childhood, they become increasing focused on navigating the peer system, which provides an acute awareness of the social hierarchy and their place in it (Gottman & Mettetal, 1986; Parker & Gottman, 1989). Some children even prioritize attaining social status over maintaining friendships (LaFontana & Cillessen, 2010). Status matters because it describes an individual’s ability to compete for and control both physical and social resources (Hawley, 1999). Previous studies have identified two forms of affective regard, separate from the peer group and behavioral reputation, that predict popularity and unpopularity: acceptance and rejection (Marks et al., 2021). However, their relative importance has been unclear because previous studies have not included both in the same model and because most studies have been concurrent, not longitudinal. Affective markers of peer regard and behavioral markers of peer group reputation are moderately correlated, making it difficult to draw conclusions from separate studies of each. Studies which incorporate measures of each are few and limited in scope. The current study was designed to examine the origins of popularity and unpopularity by disentangling affective regard from behavioral reputation using a sample of 292 students enrolled in grades 4 to 6 (ages 9-13) of a university-affiliated school.
