Title: TEMPORAL DYNAMICS OF NEGATIVE AND POSITIVE FACIAL EXPRESSION PROCESSING.
Creator: Escobar, Brian E., Hong, Sang Wook, Florida Atlantic University, Department of Psychology, Charles E. Schmidt College of Science
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. The present study examined the temporal dynamics of valence information from emotional facial expressions using electroencephalogram (EEG) in conjunction with multi-variate pattern analysis (MVPA).

Show moreThe perception and interpretation of faces provides individuals with a wealth of knowledge that enables them to navigate their social environments more successfully. The present study examined the temporal dynamics of valence information from emotional facial expressions using electroencephalogram (EEG) in conjunction with multi-variate pattern analysis (MVPA). In multiple different classifying conditions, it was demonstrated that when decoding for a positively- vs. a negatively- vs. a neutrally-valenced expression, above chance level decoding accuracy occurs sooner when compared to instances of decoding for a negatively- vs. a negatively- vs. a neutrally-valenced expression. Additionally, results showed that classification accuracy as measured by percentage of correct responses was higher in the classification condition with the positively-valenced expression versus the one with two negatively-valenced expressions. Together, these finding suggest that neural processing of facial expression may occur hierarchical manner, in that categorization between between-valence (positive vs. negative) facial expressions precedes categorization among within-valence.

Title: EVOKED POTENTIAL CORRELATES OF STIMULUS NOVELTY.
Creator: JASIUKAITIS, PAUL ALEXANDER, Florida Atlantic University, Nash, Allan J., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Sokolov's (1963) hypothesis of selective extinction of the orienting response accounts for the phenomenon of dishabituation by a discrepancy between immediate sensory input and a stored template of a habituated stimulus. The "oddball" stimulus procedure often used to elicit the P300 evoked potential waveform bears resemblance to a habituation-dishabituation paradigm. In the present experiment subjects were habituated to a 70 dB tone burst which was then occasionally replaced by 50, 60, 80 or...
Show moreSokolov's (1963) hypothesis of selective extinction of the orienting response accounts for the phenomenon of dishabituation by a discrepancy between immediate sensory input and a stored template of a habituated stimulus. The "oddball" stimulus procedure often used to elicit the P300 evoked potential waveform bears resemblance to a habituation-dishabituation paradigm. In the present experiment subjects were habituated to a 70 dB tone burst which was then occasionally replaced by 50, 60, 80 or 90 dB stimuli. According to a selective extinction model of the P300, equal absolute amounts of stimulus change should evoke equal amplitude waveforms. While the decreased intensity stimuli did evoke a P300, the largest P300s were associated with an intensity increase. The N200 component was seen to be largest with intensity decrease. It is suggested that the N200 is the evoked potential correlate of discrepancy detection which can be obscured by an intensity-driven P300.

Title: Effect of prior sensitization of stereotypy on the development of tolerance to amphetamine induced hypophagia.
Creator: Kinney, Gene G., Florida Atlantic University, Wolgin, David L., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: It was hypothesized that animals sensitized to the stereotyped behavioral effects of amphetamine would have a more difficult time developing tolerance to the hypophagic effect of the drug than nonsensitized animals. Although sensitized animals showed more intense stereotypy, they were not impaired in the development of tolerance, or in the amount of tolerance gained, thus showing a dissociation between these two variables. Differential sensitization was also shown to these effects. That is,...

Although sensitized animals showed more intense stereotypy, they were not impaired in the development of tolerance, or in the amount of tolerance gained, thus showing a dissociation between these two variables. Differential sensitization was also shown to these effects. That is, sensitized animals were not impaired on milk intake, whereas nonsensitized animals became more sensitive to the hypophagic effect of amphetamine. Further, it was found that animals sensitized to the stereotyped behavioral effects of the drug developed tolerance to this effect, and this tolerance was found to occur both in the presence and absence of milk.

Title: Global feedback in hierarchical motion pattern formation.

Abstract/Description: An array of four motion quartets (stimuli for which either horizontal or vertical motion is perceived depending on quartet aspect ratio) is arranged in a diamond configuration such that two global motion patterns are formed: (1) Rotation---alternating counterclockwise and clockwise motion is perceived, and (2) Parallel path motion---the perceived motions of all the elements are simultaneously horizontal or simultaneously vertical.

Show moreAn array of four motion quartets (stimuli for which either horizontal or vertical motion is perceived depending on quartet aspect ratio) is arranged in a diamond configuration such that two global motion patterns are formed: (1) Rotation---alternating counterclockwise and clockwise motion is perceived, and (2) Parallel path motion---the perceived motions of all the elements are simultaneously horizontal or simultaneously vertical. The perception of rotation resulted in global feedback that biases the motion perceived for an individual component motion quartet to be more consistent with rotation than aspect ratio. Stronger rotation produced greater bias. Under certain conditions, the feedback-induced bias occurred even though global rotation was not perceived. The results were interpreted in the context of neurophysiological evidence regarding neurons in Areas MT and MSTd, and a dynamical theory of motion pattern formation (Hock, Schoner & Giese, 2003; Nichols, Hock & Schoner, 2006).

Marginal support was found for the main prediction that focusing on low level details rather than high-level meaning would lead individuals to rate false high-level relational construals as more valid, although this effect was found only for those reporting on a romantic relationship, but not a close friendship. Further, exploratory analyses examining potential interaction effects demonstrated the relative influence of partner concept-clarity and relationship satisfaction on patterns of psychological emergence.

Show moreIndividuals are constantly being exposed to new information and new situations, but memory for these events is not always equal; understanding the factors that affect an individual’s ability to remember the details surrounding these events is extremely important. The purpose of the current study was to examine the potential effects of emotion and source characteristics, such as age and gender, on memory for factual information (i.e., trivia facts) and source identity (i.e., the sources of the information). One hundred and twenty-eight undergraduate students viewed a total of 120 videos depicting eight different sources (two young adult males, two young adult females, two older adult males, and two older adult females) presenting neutral and emotional (positive, negative) trivia facts; participants were then asked to complete a fill-in-thevi blank test on memory for trivia facts and a multiple-choice test on memory for the source of each fact. Results indicated that positively valenced trivia facts were remembered more often than both neutral and negatively valenced facts; emotion was not found to affect memory for the sources of trivia facts or memory for the relationship between trivia fact and source. Results indicated that trivia facts presented by female sources were remembered better than facts presented by male sources; source gender also affected memory for the sources of each fact, such that sources of facts presented by females were remembered better than the source identity for a fact presented by a male source. When the identity of the source was forgotten, participants were more likely to falsely attribute the fact to someone of the same age as the original source. If the original source was female, participants were also more likely to falsely attribute that fact to another female source compared to a male source, but if the original source was male, participants were equally likely to misattribute the source of either gender. The findings from the current study add to the current understanding of the complex effects of emotion on memory and suggest the importance

Title: Selective exposure attribution theory: Implications for better than average biases.
Creator: Kovalik, Jennifer T., Florida Atlantic University, Monson, Thomas C., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: The better than average effect refers to the tendency of individuals to perceive themselves as above average on various dimensions of social desirability (Messick, Boldizar, & Samuelson, 1985). Most research suggests that the effect results from motivations to inflate levels of self-esteem (Alicke, 1985).

Most research suggests that the effect results from motivations to inflate levels of self-esteem (Alicke, 1985). The present study challenged that an information-processing mechanism driven by selective exposure of persons to the behaviors of others may instead promote an overall negative dispositional asymmetry within a population. When subjects were asked to make assessments regarding a target's level of trait across situations permitting various levels of selective exposure, the data indicated an increased tendency to rate others more negatively when selective exposure was maximized. It was hypothesized that subjects had committed more "false negative attribution errors" and had corrected more "false positive attribution errors" upon drawing their conclusions.

After discussing the prior research which has rendered this discrepancy, I propose an experiment to reach a resolution to the discrepancy. Principles of action identification theory are used in proposing that the link between self-uncertainty and self-evaluation is moderated by the amount of evaluative threat inherent to the situation in which the self-evaluation is taking place. The experiment established that subjects who are induced to identify their actions in low level terms are more likely to exhibit biases when pursuing self-evaluations of their social ability, with the biases manifested in these subjects' preferences to be evaluated in non-diagnostic ways. The implications of this general finding and suggestions for further research are discussed.

Show moreThis study was a partial replication of one previously reported by Nash and Michels (1966). The purpose was to investigate perceptual form discrimination behavior of young squirrel monkeys as affected by contextual variables of the stimulus. The variables examined were Redundancy, Position and, of the form itself, Complexity. In addition, a sequential method of testing and recording was compared with the conventional 50-trial block procedure. Two 17 month old monkeys were tested on eight twochoice problems in a Purdue General Test Apparatus. The problems each consisted of two slides on which pairs of random shapes were presented. The shapes within each pair of slides were held constant on the parameters investigated. One slide was designated as the positive stimulus and presented in either the right or left position in random order. The number of correct responses for the 50-trial blocks, as examined by an analysis of variance, failed to reach statistical significance for any of the variables investigated. However, graphic inspection of the data suggests general agreement with the findings of Nash and Michels (1966). In comparing the two methods of testing, the sequential test of performance (STOP) was equally as effective as the conventional method and could have provided a substantial savings in test time. Comparison of scores obtained by the two procedures shows good correlation. Although no strong conclusions can be drawn from the data, they do lead to the speculation that there is a relationship between effect and extent of redundancy, and that failure of S to make a correct response in the test situation may be the result of cue sampling rather than a failure to discriminate.

Victimized children were more likely to expect retaliation for aggressing.

It has been hypothesized that sexual coercion in the context of an intimate relationship may function as a sperm competition tactic, with its occurrence related to a man's suspicions of his pmtner' s sexual infidelity. Sexual coercion in response to cues of his partner's sexual infidelity might function to introduce a male's sperm into his partner's reproductive tract at a time when there is a high risk of cuckoldry. Four studies are presented which lend support to the sperm competition hypothesis and encourage others to consider sperm competition theory when studying men's sexual coercion in intimate relationships.

Fifty-six preschoolers and their parents participated in a storytelling and discussion task, where each parent presented a happy and a sad story. Preschoolers were coded for their involvement, emotional comprehension, and concern, while parents were rated on their support, scaffolding, and expressiveness. Findings reveal that warm responsive and expressive parental behaviors contribute significantly to children’s cognitive and emotional skills during both positive and negative narrative interactions. Parents high in support and expressiveness (both during the task and within the home) had children who showed higher total expression, in addition to being more positively expressive, more involved, and more understanding of emotional concepts. These results reinforce previously established beliefs on the importance of emotionally open, positively expressive, and cognitively stimulating parent-child interactions on emotional, social, and regulatory competence.

Each tweet referenced either the Republican incumbent Donald Trump or the Democrat challenger Joe Biden. The tweets were analyzed for sentiment and the frequency of the moral foundations using the standard LIWC2015 dictionary and the Moral Foundations Dictionary 2.0. We found that the tweets had an overall negative sentiment for both candidates, with tweets referencing Trump being more negative than tweets about Biden. Additional analyses showed that the Authority (Virtue) and Loyalty (Virtue) were the most frequently used moral foundations. This study provides an overview into social media discussions during a heated election cycle that ultimately culminated in the Jan. 6th Insurrection and the second impeachment of Donald Trump.

Show moreParental sensitivity, parental intrusiveness, child involvement, and dyadic synchrony are factors associated with important developmental outcomes. The current study uses the CIB (Feldman, 1998) for a behavioral approach to investigating the effects of parental loneliness and perceived social support during the COVID-19 pandemic on parent-infant (12 􀂱 24 mo) behaviors during a free-play interaction (N = 43). The results of this study demonstrate that parental loneliness has an adverse effect on parental sensitivity and intrusiveness, but not child involvement and dyadic synchrony. Mediation analyses revealed the specific mechanisms by which low levels of perceived social support increase loneliness, which in turn, influences parents to behave more intrusively towards their infants. The findings of this study hold value for interventions that seek to reduce risk for adverse developmental outcomes. These results also hold important implications about the COVID-19 pandemic and its negative impact on parenting behaviors towards infants.

We did not find a significant difference in the GARS-2 overall scores, nor was there a difference in the GARS-2 subscale scores when examining the scores of boys and girls (both ASD and TD). Our findings suggest the GARS-2 is an excellent choice in diagnostic measures and does not appear to have a sex bias. That being said, research into ASD measures is much needed. This is a significant issue as such research does not consider the potential different symptomology of girls with ASD. The issue at the heart of this study is that for so long research on ASD has been limited to studying samples of boys with the disorder (Lundstrom et al., 2019).

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 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.

Creator: Bernardo, Angela Maria, Jones, Nancy Aaron, Florida Atlantic University, Department of Psychology, Charles E. Schmidt College of Science
Abstract/Description: Infants 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...
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.
