The Influence of Individual Differences on Emotional Processing and Emotional Memory

Johnson, Patricia Lynn 18 June 2014 (has links)
Emotional material is better remembered than neutral material and some suggest this is reflected in different Event Related potentials (ERPs) to affective stimuli by valence. Inconsistent results may be due to individual differences, specifically the behavioral inhibition/behavioral activation (BIS/BAS) motivational system. This study sought to examine the relationship between motivational systems, emotional memory, and psychophysiological response to emotional pictures. While using EEG recording, subjects were shown 150 affective pictures and given a recall and yes/no recognition task after a 20 and 30-minute delay, respectively. Overall, differences were found by valence, but not consistently based on individual trait. Controlling for arousal and mood, results did not support previous research that suggested high BIS was more responsive to negative pictures while higher BAS was more responsive to positive images. The role of ERP methodology and arousal are discussed, along with future directions.

Recognition of Facial Affect in individuals scoring high and low on Psychopathic Personality Characteristics

Ali, Afiya January 2007 (has links)
The accuracy of perception of facial emotion expressions was studied in individuals with low and high psychopathic personality characteristics in a sample of 21 male and 39 female university students. Participants completed the Psychopathic Personality Inventory (PPI), and the Behavioural Inhibition Scale and the Behavioural Activation Scale (BIS/BAS) as measures of psychopathy. Participants completed a computerised emotion recognition task containing six emotions of facial expressions (each emotion had five different intensities). The results showed that participants scoring low on the BIS and high on the BAS scores showed significant impairments in the recognition of both sad and fearful expressions. On the other hand, group scoring high on the PPI, showed significant impairment in the recognition of angry, but not fearful or sad expressions in the total sample. Males with high psychopathic personality characteristics showed significant impairments in the recognition of sad, fearful and angry expressions compared to males with low psychopathic personality characteristics. On the other hand females with high psychopathic personality characteristics showed significant impairment in recognising the expression of disgust only compared to females with low psychopathic personality characteristics. The PPI and the BIS/BAS scales showed reasonable alpha reliabilities with some exceptions for one subscale in each measure. Correlations between the PPI and the BIS/BAS scales were weak to moderate. The current findings suggest that different dimensions of psychopathy may be associated with selective impairments in recognising unpleasant emotion expressions in others.

SOCIAL TREATMENT AND ITS IMPACT ON SOCIALLY-ELEVATING CONSUMER BEHAVIOR

Popa, Monica 11 1900 (has links)
Small-talk, flattery, teasing, ridicule, threats or insults are part of the daily fabric of consumers life. This dissertation is concerned with the way consumers behave toward others depending on how they are treated themselves. Pay-it-forward is the notion that a person who is treated well by someone should be nice toward others (and conversely, a person who is treated badly may treat other people badly in turn). The present research proposes and shows that the pay-it-forward mechanism does not always occur; in fact, under certain circumstances consumers behave in a manner that contradicts it. Although research has begun to explore social influences on consumer behavior, to date a coherent theoretical account of how social treatment (i.e., the way a person acts toward another individual during a social encounter) influences consumers is lacking. This thesis offers a theoretical framework for the impact of social treatments, and tests it in four scenario-based experiments and two field studies. Results provide support for the proposed conceptual model, indicating that two dimensions of social treatment (affiliation: friendliness vs. hostility; and relevance for self-assessment: high vs. low) interactively influence consumers likelihood to engage in socially-elevating behaviors (i.e. helping another consumer, picking up the tab when dining out with others, returning money to a salesperson who accidentally gives them too much change back for a purchase). Process evidence for the underlying roles of positive/negative affect and perceived social efficacy is provided. The dissertation addresses the implications of these findings to existing theory, and identifies avenues for future research. / Marketing

Goal-Striving and Affect in Bipolar I Disorder

Fulford, Daniel 01 January 2008 (has links)
Although most research on bipolar I disorder has focused on biological models, recent investigation has elucidated the importance of psychosocial predictors of the course of illness. Theories of the Behavioral Activation System?s role in affect have helped unify biological and environmental explanations of the disorder. Along these lines, researchers have proposed that goal striving and attainment predict manic symptoms. In the current study, experience-sampling methodology was used to assess the relationship between fluctuations in goal striving and affect among 12 persons with bipolar I disorder and 12 without a history of mood disorder (control group). Participants completed measures of goal striving and affect three times each day for a period of three weeks. It was hypothesized that moving more quickly than expected toward a given goal would result in decreased subsequent effort toward that goal (coasting) for the control group, and increased subsequent effort (anti-coasting) for those with bipolar I disorder, with positive affect mediating the relationship in both cases. Results indicated that those in the bipolar I disorder group were significantly more likely to anti-coast than those in the control group. This finding, however, was explained primarily by gender, as men in the bipolar I disorder group showed no evidence of anti-coasting. In addition, there was no evidence of the mediating role of positive affect in these phenomena. Implications of the findings, limitations, and future directions are discussed.

Approach-motivated positive affect reduces broadening of attention

Gable, Philip Arvis 15 May 2009 (has links)
Research has found that positive affect broadens attention. However, the type of positive affect previously manipulated has been low in approach motivation. High approach-motivated positive affect should reduce the breadth of attention, as organisms shut out irrelevant perceptions and cognitions while they approach and attempt to acquire desired objects. Three studies examined the attentional consequences of approach-motivated positive affect states. Consistent with predictions, participants showed less global attentional focus after viewing approach-motivating positive pictures as compared to neutral pictures (Studies 1 and 2). Specifically, Study 1 used approach-motivating pictures of appetitive desserts, while Study 2 used pictures of cute animals. Neutral pictures were of varying neutral objects. Study 3 manipulated both affect and approach motivation. Less global focus was found for participants who viewed the approach-motivating pictures and had the expectancy to obtain the items as compared to other participant groups. The results indicate that high approach-motivated positive affect reduces the breadth of attentional focus, in contrast to the broadening of attentional focus that has been found with low approach-motivated positive affect.

Galperin, Inna 15 February 2011 (has links)
My research examines how different organizational phenomena function under psychological and cognitive constraints. My first study examines how audiences evaluate an established or taken-for-granted category in negative moods. Categories facilitate exchange by serving as mental models or schemas that substitute for an organization’s attributes to help audiences make sense of what they see. Established categories are further postulated to be legitimized and taken for granted by audiences. Both organizations and audiences are thought to place a high value on category membership, preferring the schema-based category to the individual attributes underlying the category. Considering the preferences of a broad audience segment about an established category, I examine the boundary conditions that can cause the schemas of a legitimized category to fail. I propose that negative mood or affect will blur the category boundary causing it to no longer be preferred to the individual attributes. I further hypothesize that negative affect will induce a reversal of preferences, and offer a unified theory as to why negative affect can cause audiences to prefer the attributes underlying the category over the category itself in their evaluations. Results from data on a representative sample of individuals support these hypotheses. In my second study, I examine how social capital accrues to individuals who were part of a group from which a member achieved prominence only after the dismantlement of the group. I employ a difference-in-differences estimation strategy to identify endogenous social effects in the context of the Hollywood film industry and find significant positive results for egos who worked with ex-post Oscar winning alters within four to six years prior to the alters’ Oscar win. Social capital effects break down, however, for length of prior years in either the too recent or too distant past. I attribute these findings to individuals’ incorrect recall of past events.

An assessment of affective skills training in a secondary teacher preparation program as perceived by student teachers, classroom supervisors, and university supervisors

Schafer, Sandra Rae 03 June 2011 (has links)
The purpose of this study was to assess the affective component of the secondary teacher preparation program at Ball State University. Three population groups enrolled during fall quarter, 1979, voluntarily took part: 1) university supervisors of secondary student teachers; 2) classroom supervisors of secondary student teachers; and 3) secondary student teachers.The assessment was conducted by means of an original instrument. The Inventory of Affective Teaching Skills measured three dimensions of responses for 21 affective teaching skills. The three response dimensions were: 1) To what extent is this skill important to effective teachers? (Valuing); 2) To what extent do you believe the skill was included in the BSU teacher training program? (Training); 3a) To what extent was the student teacher proficient in this skill? (Proficiency); and 3b) To what extent are you (the student teacher) proficient in this skill? (Proficiency). The response alternatives ranged from 1-NONE to 5-EXTENSIVE.The null hypotheses stated that there would be no differences between group responses on the three dimensions. The hypotheses were tested using the multi-variate analysis of variance F-test. Results indicated that there were significant differences between the responses of the three groups on the three dimensions. The three null hypotheses were rejected.Mean scores for each of the 21 variables (items or skills) were also examined and compared across groups and across dimensions. It was found that university supervisor group scores were highest for Valuing (3.8014, and lower for Proficiency (2.8652) and Training (2.8644). Classroom supervisor group scores were highest for Valuing (3.7165), lower for Training (3.0276) and lowest for Proficiency (2.9413). Student teacher group scores were highest for Valuing (4.0158), lower for Proficiency (3.5008), and lowest for Training (3.3436).Highest overall mean scores were from student teachers (3.6219), lower from classroom supervisors (3.2284), and lowest from university supervisors (3.1650). The overall mean scores resulted in the following rankings: lst, support pupil efforts; 2nd, motivate and involve pupils; 3rd, recognize pupil progress; 19th, use simulations and games; 20th, use objectives in disciplining; and 21st, use role-play and role-reversals.The researcher concluded that although the three groups valued the affective teaching skills, they perceived that the skills were not adequately included in the training program. Affective teaching skills which concerned general classroom interaction such as motivating, supporting, and involving pupils were ranked high. Specific affective techniques which combined affective with intellectual and analytical processes were ranked low.

The Effect of Situational Attribution Training on Majority Group Members’ Psychophysiological Responses to Out-group Members

Myers, Ashley 11 May 2012 (has links)
The present research explored the effects of Situational Attribution Training (Stewart, Latu, Kawakami, & Myers, 2010) on affective bias utilizing facial electromyography (EMG). Participants viewed a slideshow of randomly presented photographs of both and White and Black American men while rating how “friendly” each individual appeared. Simultaneously, corrugator and zygomaticus region activity, linked with positive and negative affect, respectively, was measured. Of these participants, half were randomly assigned to complete Situational Attribution Training beforehand. Results for EMG activity suggested no significant differences in EMG activity for White compared to Black photographs for either the training or control participants; thus, this study did not find evidence of affective bias by way of corrugator or zygomaticus activity. However, errors in slideshow presentation prevent clear interpretation of these results. Suggestions for future research and ways in which bias errors can be avoided are discussed.
