Title: Should Chivalry Be Dead? Benevolent Sexism and Support Provision in Close Relationships.
Creator: Colom Cruz, Adriana, Maniaci, Michael, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Three studies examined the effects of benevolent sexism and gender on support provision and relationship functioning across multiple contexts. Benevolent sexism refers to sexist attitudes towards women that are seemingly positive, but still stereotypical (Glick & Fiske, 1996). Study 1 examined benevolent sexism and dependency-oriented support in friendships by asking participants how they would respond to either a female or male acquaintance in hypothetical helping scenarios. Study 2 examined...
Show moreThree studies examined the effects of benevolent sexism and gender on support provision and relationship functioning across multiple contexts. Benevolent sexism refers to sexist attitudes towards women that are seemingly positive, but still stereotypical (Glick & Fiske, 1996). Study 1 examined benevolent sexism and dependency-oriented support in friendships by asking participants how they would respond to either a female or male acquaintance in hypothetical helping scenarios. Study 2 examined benevolent sexism and secure base support among individuals in heterosexual romantic relationships using an Internet-based survey. Secure base support differs from other forms of support in that it is not provided in order to help someone cope with adversity, but rather involves supporting a partner’s exploration or personal goal pursuit in non-adverse scenarios. Study 3 used behavioral observation to examine benevolent sexism and secure base support among romantic couples participating in a videotaped exploration task. Multiple regression and dyadic analyses were conducted to test for interactions between gender, benevolent sexism, and support provision. In both men and women in Study 1, benevolent sexism was associated with an increased likelihood of providing dependencyoriented help towards others, suggesting that men are not the only ones providing dependency-oriented support to women. However, men were more likely than women to provide dependency-oriented help towards women, regardless of their degree of benevolent sexism. In Studies 2 and 3, there were no significant main effects of benevolent sexism or gender on secure base support. In Study 2, women higher in benevolent sexism reported being more interfering towards their male partner’s goal pursuit, suggesting that benevolent sexism may be harmful to men as well. In Study 3, women reported lower feelings of competence during the exploration task than men. For individuals with partners high in benevolent sexism, gender moderated their feelings of competence. Women with male partners high in benevolent sexism reported lower feelings of competence, whereas men with female partners high in benevolent sexism reported higher feelings of competence. The mixed results suggest that the effects of benevolent sexism on support exchanges may be more complex than current theoretical perspectives imply.

Title: Types of Errors in a Memory Interference Task in Normal and Abnormal Aging.
Creator: Torres Solano, Valeria Lucia, Rosselli, Monica, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: The types of intrusion errors (Prior List, Semantically Related, and Unrelated) made on the LASSI-L verbal memory task were compared across three diagnostic groups (N = 160, 61 % female), Cognitively Normal (CN), amnestic Mild Cognitive Impairment (aMCI), and Alzheimer’s disease (AD). Errors related to Proactive, Recovery from Proactive, and Retroactive Interference were also analyzed, as well as the relationship of errors to Amyloid load, a biomarker of AD.

Show moreThe types of intrusion errors (Prior List, Semantically Related, and Unrelated) made on the LASSI-L verbal memory task were compared across three diagnostic groups (N = 160, 61 % female), Cognitively Normal (CN), amnestic Mild Cognitive Impairment (aMCI), and Alzheimer’s disease (AD). Errors related to Proactive, Recovery from Proactive, and Retroactive Interference were also analyzed, as well as the relationship of errors to Amyloid load, a biomarker of AD. Results suggest that the types of error made indicated the level of cognitive decline. It appears that as deficits increase, impaired semantic networks result in the simultaneous activation of items that are semantically related to LASSI-L words. In the aMCI group, providing a semantic cue resulted in an increased production of Semantically Related intrusions. Unrelated intrusions occurred rarely, although, a small number occurred even in the CN group, warranting further investigation. Amyloid load correlated with all intrusion errors.

The current study investigated the role of likeability and popularity in determining the relative influence that a child exercises on his or her friend’s prosocial behavior and academic achievement in a sample of elementary schooled children (N=679). The results suggest that more liked friends have more influence over their less liked friends’ prosocial behavior and academic achievement. Both more- and less-popular friends influenced each other’s academic achievement. Residualized analyses, however, which take into account the shared overlap between likeability and popularity, suggest that the more-liked friend continued to influence the prosocial behavior and academic achievement of the less-liked friend, whereas more-popular children had no influence over their less-popular counterparts.

Show moreDepression is associated with higher severity of memory disorders and has been shown to predict lower levels of cognitive functioning in those diagnosed with Mild Cognitive Impairment (MCI) or dementia. Yet, little is known about this association cross-culturally, particularly between Hispanics and European Americans. This study demonstrates that although levels of depression differed significantly across diagnostic group, Hispanics and European Americans were similar in levels of depression at each diagnosis. However, only for the European American group did depression levels predict lower scores in confrontational naming and semantic memory. Additionally, exploratory analyses of the entire sample demonstrated that lower depression predicted less likelihood of MCI or dementia diagnoses. This could indicate that there is a need for intervention and treatment of depression, in particular for later stages of MCI and dementia, that should be culturally catered to individual ethnicities.

Show moreRecent research has shown mindfulness practices to be correlated with traits frequently associated with high Executive Functioning (EF) individuals such as greater attention to specific tasks, greater working memory capacity, and the improved ability to inhibit behaviors or emotions. These three traits are highly correlated with each other, and provide an accurate assessment of an individual’s level of Executive Functioning. This study was designed to examine how individual traits associated with Mindfulness such as ‘non-judgement’ can influence attention, working memory and inhibition. This study used three self-administered questionnaires to assess traits associated with mindful individuals and three EF tests to measure performance in inhibition, task shifting and updating working memory tasks. Results showed that certain mindfulness variables from the Freberg Mindfulness Inventory and Five Facet Mindfulness Questioniare, were correlated with performance on working memory tasks while mindfulness experience was not.

Previous researchers have dealt with this problem by removing inattentive participants from data analyses. A better solution would be to prevent inattentive responding. Self-Determination Theory may provide an effective approach to reducing inattentive responding, specifically by attempting to promote autonomous motivation in research participants. Providing participants with personalized feedback may increase participants’ autonomous motivation, which in turn may lead to more attentive responding. Study 1 showed that participants who are interested in feedback are more attentive throughout an online survey than participants who are not interested in feedback. The next goal was to show through experimental manipulation that emphasizing the opportunity to receive personalized feedback would decrease levels of inattentive responding and increase autonomous motivation. No significant difference occurred between groups in levels of inattention, nor in autonomous motivation.

Title: Self-esteem Mediates Over-time Association From Parenting Practices to Adolescent Adjustment.
Creator: Huey, Melissa J., Laursen, Brett, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Adverse parenting practices have adverse effects on child outcomes, ranging from lower academic success (Dornbusch, Ritter, Leiderman, Roberts, & Fraleigh, 1987) to delinquency behavior (Steinberg, Fletcher & Darling, 1994) to adjustment difficulties (Shumow & Lomax, 2009).

Show moreAdverse parenting practices have adverse effects on child outcomes, ranging from lower academic success (Dornbusch, Ritter, Leiderman, Roberts, & Fraleigh, 1987) to delinquency behavior (Steinberg, Fletcher & Darling, 1994) to adjustment difficulties (Shumow & Lomax, 2009). There is considerable evidence linking poor parenting practices to increases in adolescent adjustment symptoms (e.g. Barnes, Reifman, Farrell, & Dintcheff, 2000). It is likely that there is an explanatory mechanism driving this relationship. The current study tests the hypotheses that associations between adverse parenting behaviors are both directly associated with adjustment problems, and indirectly associated with maladjustment via changes in self-views. A staggered cohort longitudinal design was employed that included a total of 453 (215 boys, 238 girls) 9th graders and 464 (231 boys, 233 girls) 10th graders at the first assessment in spring, 2013. At the onset of the study, adolescents completed scales describing parental monitoring (Small & Kerns, 1993), parental psychological control (Barber, 1996), and parental connectedness (Arnold, Nott, & Meinhold, 2012). Adolescents also described indices of self-esteem (Rosenberg, 1965), self-efficacy (Schwarzer & Jerusalem, 1995), and adjustment behaviors (Achenbach & Rescorla, 2001). Results from the direct effects models revealed parenting practices have a direct effect on adolescent adjustment. Mediation models revealed indirect links between parenting practices and adolescent adjustment via self-esteem. Greater parental psychological control and less parental connectedness was linked to decreases in selfesteem one year later, and lower levels of self-esteem were in turn, associated with increases in adolescent adjustment problems. This study provides insight on the impact that parenting practices have on adolescents both directly and indirectly. Parents should understand that even though adolescents are seeking autonomy and separation, practicing attentive and meaningful parenting is just as important during adolescence as it is during any other periods of development.

Title: The Development of Synchronous Vocalizations and Behaviors in Juvenile Male Wild Atlantic Spotted Dolphins.
Creator: Myers, Alyson J., Bjorklund, David F., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: The ability of adult wild Atlantic spotted dolphins (Stenella frontalis) to synchronize vocalizations and behaviors has been found to be a key factor in overcoming much larger bottlenose dolphins during interspecies aggression (Cusick & Herzing, 2014).

Show moreThe ability of adult wild Atlantic spotted dolphins (Stenella frontalis) to synchronize vocalizations and behaviors has been found to be a key factor in overcoming much larger bottlenose dolphins during interspecies aggression (Cusick & Herzing, 2014). Furthermore, an adult baseline of behaviors and vocalizations during aggressive events containing synchrony has been established (Myers, Herzing, & Bjorklund, 2017). The present study examines juvenile aggression that contains bouts of synchrony to look at the development of this valuable skill. Differences of duration between adult and juvenile synchronous bouts, lag sequential analyses, frequencies of behavioral classes depending on the age class of the aggressor-recipient dynamic, differences in the frequencies of behavioral classes depending on the synchronous state and aggressorrecipient dynamic, and differences in behavioral classes exhibited by adults and juveniles during different synchronous states were analyzed. Adults, across group size, were able to maintain physical synchrony for a longer duration. Juveniles were often in loose synchronous groups before forming into a tight synchronous group as seen in adult synchrony. Vocal synchrony during adult aggression in terms of synchronized squawks were longer in duration than vocal synchrony during juvenile aggression. Juveniles used more pursuit behaviors during aggression, which indicates practice of a behavior that was found to be the most frequently used in interspecies aggression (Volker, 2016). Additionally, when adults were present in juvenile aggression, they used fewer aggressive behavioral classes demonstrating self-handicapping based on their opponent. This illustrates that there is a learning period for both vocal and physical synchrony for juvenile dolphins and that juvenile aggression, or play-fighting, is an important aspect of the development of these skills. This study is the first to describe juvenile synchrony in a population of wild Atlantic spotted dolphins.

Show moreInattentive responding by research participants may decrease the reliability and validity of self-report measures. The current studies broaden the record of personality traits correlated with inattention by examining individual differences in attachment anxiety and avoidance among adults in romantic relationships. Based upon the characteristics typically exhibited by adults high on attachment avoidance, I expected an overlap between this personality trait and inattention, such that participants higher on attachment avoidance would exhibit higher levels of inattentive responding when answering self-report questions about their relationship. Two studies addressed this hypothesis using both self-report data from individuals and partner-report data from romantic couples to examine the association between a participant’s attachment avoidance and their level of inattentive responding while participating in research focusing on their romantic relationships. Self-reported attachment avoidance was associated with greater inattentive responding in both studies. However, partner-reported attachment avoidance was not significantly associated with inattentive responding in Study 2.

Show moreAn EEG experiment was design to test the influence of level of proficiency on processing of emotion content between languages in a sample of Spanish-English bilinguals divided by proficiency levels between two groups of bilinguals, one group of balanced (n=23) and another of unbalanced bilinguals (n=26). The participants rated words in three categories (negative, neutral, and positive) in terms of emotional valence in English and Spanish while EEG was recorded. Event-related potentials were calculated for two components related to emotion processing: the early posterior negativity (EPN) and the late positive complex LPC. 2 (Bilingual group) x 2 (language) x 3 (valence) x 3 (electrode) analyses were conducted on each component, separately for latency and amplitude. The results for the EPN latency indicated a marginally significant valence effect, with emotion words presenting shorter latencies than neutral words across conditions indicating a processing advantage of emotion content in both languages. The EPN amplitude also reflected the effect of valence, with larger amplitudes both emotion categories than for neutral words. The overall EPN amplitude was larger in Spanish than in English for both bilingual groups across valence categories. The LPC latency was longer in English than in Spanish for both bilingual groups, possibly related to Spanish being identified as native language in most of the sample. The LPC amplitude was larger for negative than for emotion than for neutral words for both groups in English and in Spanish for the Balanced group. The Unbalanced group, however, presented larger for positive than for neutral, and for neutral than for negative words. These results suggest that the Balanced and Unbalanced groups process emotion content similarly in English, but differently in Spanish. The Valence effects were consistent across languages for the Balanced group, but not for the Unbalanced group which might reflect an attenuation of the valence effect for negative words in Spanish for this group, and could indicate weaker emotional reactivity to negative words in the less proficient language.

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.

Pairs were matched accordlng to the number of trials requtred to reach a criterion of 18/20 correct responses then randomly assigned to one of two grouos for testing In transposition. Both groups were tested on the orlgtnally positive stimulus and a brighter one: 1.25 ft/cd for Group 8-C and 5.38 ft/cd for Group 8-D. By testing for transposttlon wtth non-reinforced trials, contrary to the usual method, a tendency toward converging measures of transposltton was achteved. Transposition for Group 8-D, In the situation most dissimilar to training, was greater than for 8-C. These results were discussed from relational or Gestalt, Spence model, and Adaptation Level positions and It was shown that the results are contrary to traditional Gestalt predictions. It was oredlcted that, according to underlying assumptions of the Spence model, with continued non-reinforced trials, per cent of transposition for both groups would decrease until a chance level of responding was reached. That this did not occur cannot be explained by the Spence model. Because the variability was too great with such a small N, these results did not reach the .05 level of probability.

Show moreThe observation of contrast effects (CE) in response to differential relnforcenent has subsequently elicited a diversity of experimental results and theoretical interpretations. Adaptation Level (AL ) concepts have provided a mechanism for integrating such data within a psychophysical frame-of-reference approach. The application of this approach to the somewhat neglected area of response-produced stimuli associated with effort, suggests that proprioceptive stimuli may be effectively evaluated in a simllar manner. Following shifts in the amount of effort required to produce a constant reward magnitude, performance measures demonstrated positive and negative contrast effects (PCE; NCE) in relation to an appropriate control performance. Data analysis suggested that the combined effects of greater effort and shift conditions tended to increase resistance to extinction. The findings are not consistent Kith traditional (e. g., Hull, Spence) concepts with regard to CE and the influence of effort on performance. It is suggested that such effects are more consistent with a contextual, or frame-of- reference, viewpoint.

Immediately following this period the Ss were allowed to respond under continuous reinforcement to a postadaptation stimulus of 236.90 apparent foot-candles. Measurement in terms of bar pressing indicated that the four groups extinguished differentially over six days. The control group, for whom the discrepancy bwtween preadaptation magnitude and postadaptation stimulus remained zero, was found most resistant to extiction during this period. Additionally, increases in the discrepancy between the pre- and postadaptation magnitudes led to experimental groups. The implications of these data for the proposition of stimulus definitions in terms of behaviorally effective magnitudes were discussed.

Either testosterone or an oil vehicle was injected into bobwhite quail eggs prior to incubation. Control eggs were unmanipulated.

All groups demonstrated a preference for the familiar call (p < .05), but minimal between group difference were found. Contrary to previous research, elevated yolk testosterone neither facilitated nor impaired postnatal auditory learning in bobwhite quail chicks. Further research will examine underlying mechanisms responsible for differential effects and explore if similar systems are involved in other species-typical processes such as social motivation.

Show moreObjects in a scene are likely to occlude other objects partially and are itself likely to be partially occluded. A central question, therefore, is how the visual system resolves the resulting surface correspondence problem by successfully determining which surfaces belong to which objects. To this end, a recently developed dynamic grouping methodology has determined whether pairs of adjacent surfaces are grouped (Hock & Nichols, 2012). The grouping of adjacent surfaces, which depends on their affinity state, is indicated by the direction of perceived motion across one surface when its luminance is perturbed. In the current stimuli, which consists of a horizontal surface partially occluded by a vertical bar, dynamic grouping also can occur for nonadjacent surfaces, providing they are linked in two-dimensions by a connecting surface. Results indicate that the dynamic grouping motion is stronger for amodal completion entailing the perceptual grouping of nonadjacent surfaces behind an occluder.

Study 1 compared the English skill of 116 5 year olds who had been exposed to English and Spanish from birth with English monolingual and found that the bilingual children had significantly lower levels of vocabulary skill. Study 2 assessed 65 adult bilinguals, comparing them to 25 English and 25 Spanish monolinguals on a battery of language measures. The bilinguals had lower scores in Spanish in 7 of the 8 domains of language skill measured. The bilinguals were not different from the English monolingual speakers in most, but not all, aspects of language proficiency. These findings provide evidence that the monolingual-bilingual gap observed in childhood is no longer evident among adult bilinguals, but that despite early exposure and continued use into adulthood, second generation immigrants are not native-like in their heritage language skills.

Title: Self-Organization of Object-Level Visual Representations via Enforcement of Structured Sparsity in Deep Neural Networks.
Creator: LaCombe, Daniel C. Jr., Barenholtz, Elan, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: A hypothesis for the self-organization of receptive fields throughout the hierarchy of biological vision is empirically tested using simulations of deep artificial neural networks. Results from many fields for topographic organization of receptive fields throughout the visual hierarchy remain disconnected. Although extensive simulation research has been done to model topographic organization in early visual areas, little to no research has investigated such organization in higher visual areas...
Show moreA hypothesis for the self-organization of receptive fields throughout the hierarchy of biological vision is empirically tested using simulations of deep artificial neural networks. Results from many fields for topographic organization of receptive fields throughout the visual hierarchy remain disconnected. Although extensive simulation research has been done to model topographic organization in early visual areas, little to no research has investigated such organization in higher visual areas. We propose that parsimonious structured sparsity principles, that permit the learning of topographic receptive fields in simulated visual areas, are sufficient for the emergence of a semantic topology in object-level representations of a deep neural network. These findings suggest wide-reaching implications for the functional organization of the biological visual system and we conjecture that such observed results in nature could serve as the foundation for unsupervised learning of taxonomic and semantic relations between entities in the world.

Title: Patterns of Early Dual Language Proficiency: Correlates, Changes, and Stability From 2.5 Years Through 4 Years.
Creator: Ramirez, Nicolette, Hoff, Erika, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Research indicates that there are numerous factors related to dual language proficiency. Furthermore, research suggests that the language skills of bilingual children are very heterogeneous. In this study, we will focus on four outcomes for those receiving dual language input. Those four patterns of outcome are as follows: bilingual children can have high levels of skills in English and Spanish, high skills in English and low skills in the Spanish or vice versa, or low levels of skills in...
Show moreResearch indicates that there are numerous factors related to dual language proficiency. Furthermore, research suggests that the language skills of bilingual children are very heterogeneous. In this study, we will focus on four outcomes for those receiving dual language input. Those four patterns of outcome are as follows: bilingual children can have high levels of skills in English and Spanish, high skills in English and low skills in the Spanish or vice versa, or low levels of skills in English and Spanish. The present study focused on the prevalence of these four patterns and their concurrent correlates amongst 30 month old (N = 87, 48 females) and 48 month old (N = 74, 40 females) simultaneous English-Spanish bilinguals with special emphasis on the distinguishing factors for those with high dual language skills. Overall, for those with high dual scores, the findings reveal that gender, birth-order, and maternal level of education are predictive of high dual language scores so that members of this group are largely first-born females of mothers with an average 15.8 years of education. English dominant scores were predicted by percent English input in the home and birth-order so that children in this group were mostly later-born children with 65% English input in the home. Spanish dominant scores were predicted by percent English input in the home and Spanish bookreading behaviors as children in this group received 23% of their in-home input in English and were read to for more than one hour per week in Spanish. Low dual scores were marginally predicted by gender and Spanish book-reading behaviors, children in this group were mostly male and received less than an in hour of Spanish reading per week.

Title: Maternal influence on early infant emotional regulation: A study of 3-month infant behavior, cortisol and frontal EEG.
Creator: Sloan, Aliza T., Jones, Nancy Aaron, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Prenatal maternal stress and mood, and early postnatal mother-infant interactions set the stage for the child’s psychobiological, neurological and social development. While a large body of research connecting maternal depression to infant EEG asymmetry exists, the current study sought to add to the sparse literature on maternal anxiety and infant EEG. Mother-infant dyads were assessed prenatally during the third trimester, soon after birth, at 6 weeks and 3 months postnatal. Association...
Show morePrenatal maternal stress and mood, and early postnatal mother-infant interactions set the stage for the child’s psychobiological, neurological and social development. While a large body of research connecting maternal depression to infant EEG asymmetry exists, the current study sought to add to the sparse literature on maternal anxiety and infant EEG. Mother-infant dyads were assessed prenatally during the third trimester, soon after birth, at 6 weeks and 3 months postnatal. Association between maternal depression and later development of right mid-frontal alpha asymmetry was confirmed, while trends suggested maternal anxiety may be associated with lateral frontal alpha asymmetry. Greater maternal sensitivity and anxiety were each associated with lower post-stressor cortisol in infants with right frontal asymmetry. Greater time spent in mutual gaze was associated with positive infant affect. Finally, quality mother-infant dynamics encourage positive infant affect and healthy physiological stress regulation even when brain patterns associated with dysregulation have been established.
