The Impact Of Situational Context On Children's Social Information Processing: The Proximal Influence Of Friends

Smith-Schrant, Heather L 09 March 2009 (has links)
There is increasing recognition that contextual aspects of social situations are important determinants of children's social information processing. While it is generally accepted that friends influence children's social behavior, the immediate influence of a friend in specific conflict situations is less understood. Contextualized vignettes depicting hypothetical peer conflict situations were developed to examine the impact of situational context, namely a friend's suggested attribution and an antagonist action cue, on students' social information processing. A repeated measures design examined the proximal influence of situational context on 4th and 5th grade students' (N=367) own intent attributions, emotional reactions, and response evaluations to hypothetical peer conflict scenarios. Results indicated that situational context is important to students' social cognition. Students adjusted their social cognition and emotion in response to cues to an antagonist's intent and were influenced by a friend's comments during peer conflict scenarios. Students' responses were more aligned with the antagonist's action than a friend's suggested attribution. However, a friends' attribution was influential in situations where it conflicted with the antagonist's action. Results of this study help to increase knowledge regarding the context of social cognition and can assist in the development of more ecologically valid social skill interventions.

Prediction is Not Enough: Towards the Development of a Multi-Faceted, Theoretical Model of Aggression and Violence

Cohn, Jonathan Reed 08 1900 (has links)
Violence and aggression continue to be both public health and economic concerns. The field of violence prediction has undergone a series of changes in an attempt to best assess risk including using unstructured clinical judgment, actuarial measures, and structured professional judgment. Although prediction has become more accurate with improved measures, a new generation has recently emerged with an emphasis on understanding violence, as opposed to merely predicting it, to shift the focus towards violence prevention. In addition to the creation of measures, researchers have sought to identify specific risk factors for aggression and violence including static and dynamic risk factors. Despite research demonstrating associations between neuropsychological and social-cognitive factors, violence risk measures continue to omit these variables. The current study developed a multi-faceted, theoretical model of aggression including social-cognitive, neuropsychological, personality, and psychiatric factors. A community, male sample (N = 1,192) collected through Amazon's MTurk responded to a series of self-report measures and neuropsychological tasks. Utilizing structural equation modeling (SEM), I created a model predicting aggression. Several important paths were significant including from entity theory to aggression, mediated by hostile attribution bias, schizotypy to aggression, mediated by both hostile attribution bias and disinhibition, substance use to aggression mediated by disinhibition, and psychopathy to aggression directly. This model provides a framework for future research that focuses on process factors of violence and aggression.

Executive Functioning Processes in Simple and Complex Theory of Mind Tasks

Shamji, Jabeen Fatima 08 1900 (has links)
Using a multimethod-multimodal approach, this study compared the contributions of executive function (EF) abilities (Go No-Go, Visual Search, 2-Back task, and Task Switching) to narrative comprehension tasks (False Belief, Strange Stories, Self-Reported Theory of Mind Inventory [TOMI-SR]) and a narrative production task (interpersonal decentering) in a sample of young adults. Separate regression models were conducted for each theory of mind (ToM) measure with EF measures as predictor variables and empirically selected demographic variables controlled. As expected, in this college student sample (N = 110), False Belief demonstrated a ceiling effect and was not associated with any EF ability. Task Switching and 2-Back accounted for significant variance in Strange Stories. No EF task significantly predicted performance on TOMI-SR or interpersonal decentering. Both story comprehension tasks (False Belief and Strange Stories) were significantly associated, but these tasks were not correlated with either self-reported ToM or interpersonal decentering. Several unanticipated demographic associations were found; having more siblings and English proficiency accounted for significant variability in Strange Stories; education, presence or absence of self-disclosed autism diagnosis and mental health diagnosis explained a large portion of variance in TOMI-SR; interpersonal decentering maturity differed significantly between cisgender men and cisgender women. Lastly, interpersonal decentering number of interactions demonstrated an advantage for individuals without diagnosed or suspected autism diagnosis. This study raises critical concerns regarding measurement method error variance and variability of task demands in explaining cognitive mechanisms relevant to social cognitive processes.

Understanding of human communicative motives in domestic dogs

Pettersson, Helene January 2009 (has links)
<p>I investigated the understanding of human communicative motives in domestic dogs. Dogs use human communicative cues, like the pointing gesture when searching for hidden food, but it is uncertain how dogs interpret human communication. 32 dogs were presented with two communicative contexts in an object choice task experimental design. In a cooperative context the experimenter informed the subject where food was hidden by pointing and giving a verbal indication. In a competitive context the experimenter held out her arm towards the correct location in a stop gesture and firmly said no. To be successful in the competitive context the subject had to understand the experimenters communicative motive and make an inference from the prohibition (i.e. she would only prohibit it if there was something good there). The average correct choices were compared between the conditions. The dogs successfully followed the cooperative communication. They showed a trend towards choosing the baited cup in the competitive condition. A second study tested if the stop gesture affected the dogs’ choice, since it is not known how dogs interpret gestures. The pointing cue was now presented with the prohibiting command and the stop gesture was presented with the cooperative verbal cue. The dogs used the cooperative communication but did not understand the competitive context. A difference between the contexts was found. The dogs did not differentiate between the gestures. In conclusion dogs do not make inferences from competitive communication or prohibition but are specialized in utilizing cooperative communication</p>

Social Cognition: Theory and Neuroscience in Fetal Alcohol Spectrum Disorders

Stevens, Sara 31 August 2012 (has links)
Children with fetal alcohol spectrum disorders (FASD) have deficits across many cognitive, behaviour and social domains. However, despite social difficulty being proposed as a main deficit following prenatal alcohol exposure, the nature of their deficient social behaviour is largely unknown. One process that may underlie difficulties in social functioning is poor social cognition, which refers to one’s understanding of the self, others and social world. The primary goal of this dissertation was to determine whether social cognitive deficits represent a core disability underlying the socio-behavioural problems of FASD using a bottom-up approach. The first level of this approach is represented by face processing. Global and independent face feature processing was compared between FASD and normal controls (NC) using experimental and clinical measures. Eye gaze processing was investigated next using experimental and clinical tasks. At the highest level of the bottom-up approach, social perspective taking, including theory of mind and empathy were examined, along with how these abilities related to parent-rated behaviour. Finally, the lowest level consisted of specific aspects of the social neural network. White matter in three limbic pathways was investigated using diffusion tensor imaging (DTI). Results generally supported the bottom-up approach of social cognition in FASD. These children showed impaired processing of face features, when matching mouth shapes and partially occluded identity, compared with NC. The FASD group was slower to process gaze and arrow cues, suggesting impaired attention shifting. Children with FASD also showed impairments in social perspective taking, including understanding false beliefs and empathy, and these impairments were related to parent-rated attention and social problems, and autistic-like traits. Deficits in theory of mind got worse with age in FASD and empathy showed distinct sex-related differences. Although no group differences were observed on DTI indices, groups did show different age-related changes in white matter. In conclusion, deficits at each level of the current bottom-up approach may underlie the social impairments in FASD and may contribute to their broader social behavioural phenotype. The results from this dissertation have potential to inform clinical practice and lead to more effective diagnostic and treatment approaches in FASD.

Measures of Social Cognition in the Laboratory and Real World: Towards Temporal Dynamics of Implicit Other-Regard

Tucci, Danielle 12 May 2012 (has links)
Social cognition is a fundamental aspect of human experience that enables us to have relationships with and understanding of other people. Social relationships have been shown to mitigate cognitive decline in old age and benefit cognitive functioning, and the social interaction on which these relationships rely requires an extensive network of cognitive processes, and by extension neural systems, that have not, as of yet, been widely studied in older adults. Nor has the function of these systems been tied to social relationships in the real world. Here, I will compare self-reports of real-world quality and extent of social networks with behavioral and neural measures of other-regard in the laboratory. It is hoped that by so doing we will be able to link social neuroscientific measures in the laboratory with persons’ perceptions of the quality and extent of their social relationships. In this study, other-regard in older adults was operationalized with a reaction-time measure in an implicit turn-taking task, neural measures were provided by dense array EEG, and all participants also completed self-report measures of empathy subscales and of the quality and extent of their social networks. I found that measures of empathic personal distress decreased with increased other-regard (r = -0.36, p = 0.01, beta = 0.47), while increased quality and extent of social networks associated marginally with increased other-regard (r = 0.20, p = 0.11, beta = 0.39). Neural analyses are ongoing and are expected to show differential activation consistent with cognitive processes such as theory of mind, empathy, joint attention, and executive control.

Långsammare igenkänning av emotioner i ansiktsuttryck hos individer med utmattningssyndrom : En pilotstudie

Löfdahl, Tomas, Wretman, Mattias January 2012 (has links)
Syftet med denna pilotstudie var att skapa hypoteser om och hur utmattningssyndrom påverkar förmågan att känna igen emotioner i ansiktsuttryck. En grupp patienter med utmattningssyndrom jämfördes med en matchad frisk kontrollgrupp (N=14). Grupperna undersöktes med ett datorbaserat test beståendes av färgbilder av autentiska ansiktsuttryck som gradvis i steg om 10% förändrades från ett neutralt ansiktsuttryck till någon av de fem grundemotionerna ilska, avsky, rädsla, glädje och ledsenhet. Mätningarna gjordes i termer av igenkänningsprecision och responshastighet. Resultatet visade att patientgruppen responderade signifikant långsammare än kontrollgruppen sett över samtliga emotioner i testet. Inga emotionsspecifika skillnader såväl som skillnader i igenkänningsprecision kunde påvisas mellan grupperna. Orsakerna till diskrepansen i responshastighet diskuterades utifrån fyra tänkbara förklaringsområden: ansiktsperceptuell funktion, visuell uppmärksamhet, självfokuserad uppmärksamhet samt noggrannhet/oro. Rekommendationer gjordes till framtida forskning om att utforska dessa områden närmare.
