An Investigation of the Psychological Processes Involved in Juror Rehabilitation
Year of Dissertation:
Judges often attempt to rehabilitate jurors who express an inability to be fair during voir dire. The present research examined psychological mechanisms operating during juror rehabilitation. Study One investigated whether the influence of rehabilitative questioning on juror judgments observed in previous research is attributable to informational or normative influence from the judge. I manipulated the presence of two components of rehabilitation (i.e., legal instruction and elicitation of a commitment to forgo bias) within a mock voir dire. I also varied evidence strength to assess whether rehabilitative questioning improves the quality of jurors' judgments. Jurors watched a trial and rendered a verdict. Rehabilitative instructions reduced the number of guilty verdicts for biased and unbiased participants. Rehabilitation did not increase jurors' sensitivity to evidence strength. Study Two tested the hypothesis that traditional suppression rehabilitation will lead to increased accessibility of PTP under conditions of cognitive load. I manipulated exposure to PTP and the type of rehabilitation questioning received (i.e., no rehabilitation, rehabilitation framed in terms of suppression, rehabilitation framed in terms of concentration). Efforts were taken to induce a state of cognitive busyness in all participants while they watched the trial; after the trial participants deliberated to a verdict. Exposure to PTP increased the likelihood that participants would vote guilty. In the no rehabilitation and concentration conditions, participants who read PTP perceived the defendant as more guilty than did participants who did not view PTP. However, in the suppression rehabilitation condition, participants who read PTP perceived the defendant as less guilty than did participants who did not read PTP. Rehabilitative instructions and suppression rehabilitation resulted in more lenient judgments than the no-rehabilitation control, suggesting that participants were not well calibrated to the magnitude of their bias, and when prompted to be unbiased, overcorrected in the opposite direction. Although rehabilitated jurors may be motivated to correct for bias, they appear to have difficulty estimating the degree to which biases influence their judgments. It is possible that jurors may be better able to assess the presence of and correct for a biasing influence if it is discrete rather than attitudinal in nature.
The Relationship Specificity of the Reflective Function: An Empirical Investigation
Year of Dissertation:
The present study examines the stability of the Reflective Function (RF) across relationship contexts by testing the correlation between mothers' RF in discussing their children/parenthood and their RF in discussing their parents/childhood. It was hypothesized that RF would be stable across these contexts as evidenced by a positive, significant correlation between RF scores on separate interviews that focus on parenthood and childhood in detail. Subjects were 40 first-time mothers between the ages of 25 and 40, all of whom were middle-class and in stable, cohabiting relationships at the time of the study. They were interviewed using the Adult Attachment Interview (George, Kaplan, & Main, 1996) while in the third trimester of pregnancy, and with the Parent Development Interview (Slade, Aber, Bresgi, Berger & Kaplan, 2003) when their children were 10 months old. The Reflective Function Manual for Application to Adult Attachment Interviews (Fonagy, Steele, Steele, & Target, 1998) was used to determine the level of RF regarding childhood, and the Addendum to the Reflective Function Manual for use with the Parent Development Interview (Slade, Bernbach, Grienenberger, Levy, & Locker, 1999) was used to determine the level of RF regarding parenthood. Results supported the study's hypothesis: There was a highly significant, positive correlation between RF scores across the two interviews. These results are discussed in terms of their implications for attachment theory, the theory of mentalization and affect regulation, psychoanalysis, and clinical treatment. In order to form hypotheses about the potential sources of unstable RF, qualitative analyses are performed on two subjects with significantly discrepant scores across interviews.
THE DIFFERENT MEANINGS OF HOME FOR RESIDENTS AND PROFESSIONALS IN THE PLANNING AND DESIGN OF SOCIAL HOUSING IN COLOMBIA
Year of Dissertation:
This dissertation compares and contrasts the perspectives of residents and housing related professionals involved in a social housing program in Bogotá, Colombia to offer an in-depth understanding of how different meanings of `home' influence the production and consumption of housing. It is based on the crucial need for architects, planners, and housing policy-makers to better understand the experiences of residents in the housing that they help to create. This study focuses on two of Metrovivienda's master-planned communities and illustrates the multiple perspectives of residents and housing related professionals through the rubric of an "emerging housing practice" (Ferguson & Navarrete, 2003). This practice encompasses four dimensions of what it means to create and live in these new communities: the meanings of homeownership, experiences in formal urbanizing spaces, misunderstandings and problems that arise from living under a `new' horizontal property scheme, and strained attempts at ameliorating housing complex convivencia (mutual co-existence) issues via housing governance. This exploration of people's meanings also reveals an underlying story of how these dimensions function as both city-building and citizenship-building projects of the state. The dissertation concludes with the argument that social housing is designed by the state to contribute to its citizenship goals of fostering convivencia. It does this through the horizontal property law and systems of local governance that are new and unexpected by the residents. The study builds on interdisciplinary literature from environmental psychology and the social sciences, together with architecture and urban planning theory. It adopts a narrative inquiry approach in order to provide a complementary perspective to the largely quantitative field of housing studies. Specifically, data are comprised of 24 in-depth narrative interviews of residents and professionals, additional informal interviews with professionals, participant-observation field notes, a discussion group, and document research. Fieldwork was conducted in 2010 and 2011. The findings have direct implications in Colombia, as this model of social housing is currently being expanded by national and local governmental initiatives.
Unraveling the Longitudinal Relationship Between ADHD and Anxiety Disorders: The Contribution of Parenting
Year of Dissertation:
Background: The substantially elevated risk for anxiety disorders among children with attention-deficit/hyperactivity disorder (ADHD) is well documented, although a causal explanation for the high comorbidity has yet to be identified. Objective:To investigate the extent to which ADHD in young children affects parenting practices, which, in turn, place children at risk for anxiety disorders. Method: A sample of 200 children was assessed at ages 3-4 years (Baseline; BL) and at three follow-up time-points (ages 5, 6, and 8 years). Presence or absence of ADHD at BL and presence or absence of anxiety disorder at ages 6 and 8 were determined via semi-structured interview with parents. Parenting behaviors were ascertained at BL, age 5, and age 6, via parental self-report on the Alabama Parenting Questionnaire - Preschool Revision (APQ-PR) and observer-coded video recordings of parent-child interactions (PCI) within the lab. Results: (1) Age 3-4 ADHD predicted greater rates of anxiety disorders at age 8. (2) Early ADHD predicted less parent-rated positive parenting at ages 5-6 and more observer-rated parental negative emotionality and lack of respect for autonomy at ages 3-4 and 5; early ADHD also predicted poorer observer-rated quality of support in parents of 6 year-olds. (3) Lower parent-rated positive parenting between the ages of 3 and 5 years, and higher observer-rated parental negative expressions of emotion at ages 5 and 6, were predictive of child anxiety disorders at age 8, even after controlling for early temperament. (4) Mediation analyses found parenting, particularly that characterized by rejection, low warmth, and poor positive contingency management, to partially mediate the relationship between preschool ADHD and age 8 anxiety disorders. Conclusions: Parenting plays an important role in contributing to or alleviating risk for the development of anxiety disorders in children with ADHD. Implications for prevention and intervention are discussed.
The Effects of Pre- and Post-Venire Publicity on Juror Decision Making
Year of Dissertation:
Given the proliferation of the media in everyday life, finding jurors who have not been exposed to potentially biasing pretrial publicity (PTP) is somewhat of a challenge, especially in high profile cases. This has long been recognized by the courts, but some question the effectiveness of the remedies that have been put in place. Over the past 45 years, psychologists have studied these effects to understand whether and how PTP influences juror decision making. This research has shown that PTP effects do indeed exist and can jeopardize the defendant's right to a fair an impartial trial. At the same time, some have questioned the methodological rigor of these studies and their applicability to the trial setting. Additionally, some important questions remain, specifically the durability of PTP effects, the influence of quantity and type of PTP (pro-prosecution vs. pro-defense), the medium of exposure (print vs. television), and the influence of mid-trial publicity. This study was designed to address these questions by investigating the influence of pre- and post-venire publicity on juror decision making. The purpose of this study was (1) to examine the durability of PTP effects, (2) to examine the influence of pro-prosecution and pro-defense PTP on decision making, (3) to examine the influence of natural vs. experimentally manipulated PTP, (4) to examine the influence of amount of PTP exposure on decision making, (5) to examine the influence of medium of PTP, (6) to examine the influence of post-venire publicity, and (7) to add to the external validity of PTP effects. It was proposed that depending on the media slant jurors are exposed to - a pro-prosecution slant or a pro-defense slant -- their perceptions and inferences will be distorted in the direction of the favored party. This has significant legal implications as many news media sources are substantially biased in one direction or the other and this exposure could influence decision making. The results revealed that participants were significantly influenced by the slant of the PTP they were exposed to. Specifically, participants in the pro-defense condition were more likely to render not guilty verdicts as compared to those in the pro-prosecution condition, and this effect lasted throughout the duration of the trial. Additionally PTP exposure significantly distorted participants' perceptions of witnesses at all points in the trial. Secondly, a finding of no significant difference of the effect of exposure slant between the naturally exposed, and experimentally exposed samples provide support for the external validity of laboratory studies examining PTP effects. In addition, quantity of PTP influenced decision making, such that those exposed to greater quantities of PTP tended to be more biased. Finally, medium of PTP and post-venire publicity exposure had no significant influence on decision making. Results provide support for the pervasive and persistent nature of PTP effects on juror decision making.

In two separate series of behavioral experiments, spatial resolution and perceptual dimensions corresponding to physical stimulus attributes (frequency, amplitude and position) of a vibratory dipole source were assessed using classically conditioned respiratory suppression in goldfish (Carassius auratus).
Reflective Functioning and Differentiation-Relatedness During Pregnancy and Infant Attachment Outcomes at One Year
Year of Dissertation:
This study compared maternal reflective functioning (RF) and differentiation-relatedness (DR) during pregnancy and examined how these processes relate to the quality of mother-infant attachment at one year. The subjects were 35 mother-infant pairs drawn from the control group of a longitudinal treatment study, "Minding the Baby (MTB)," a federally and privately funded home intervention program developed jointly by the Yale School of Nursing and Yale Child Study Center, led by Drs. Lois Sadler and Arietta Slade, and targeting a low socio-economic status area of New Haven, CT. The Pregnancy Interview (Slade, 2003) was administered to the women (ages 14-25 years) during the third trimester of pregnancy, and quality of attachment was assessed when infants were 14 months using the Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978; Main & Solomon, 1990). The DR scoring system, the Differentiation-Relatedness Scale of Self and Object Representations (Diamond, Blatt, Stayner, & Kaslow, 2011), was adapted for use with the Pregnancy Interview to provide a manual for this study (Daley, 2012). Lowest, highest, and most typical DR ratings were captured for self, the woman's mother, the father of the baby, and the baby. The mean for the baby, at 3.03, was one DR point lower than other relationship means. Three composite scores were created, averaging across relationships: Low DR, High DR, and Overall DR. Results indicated that maternal RF was correlated with Overall DR and High DR; however, none of these variables distinguished between attachment outcomes. In contrast, Low DR distinguished, with a large effect size (d = .92), between disorganized and secure attachment outcomes (p = .026), and, in post-hoc analyses, between disorganized and all organized outcomes. For the disorganized group, Low DR often dropped to self-other boundary confusion (level 2) across relationships. This suggests that, for a population of women on the lower end of the RF Scale, transient regression to non-differentiated states during pregnancy is a risk factor for disorganized infant attachment outcomes at one year. Results have implications for early identification of high-risk dyads and refinement of intervention models.
Characterization of Somatosensory Processing in Relation to Schizotypal Traits in a Sample of Nonclinical Young Adults
Year of Dissertation:
A core feature of schizophrenia spectrum disorders (SSDs) is a basic sensory (e.g., visual, auditory) processing disruption, yet few studies have examined somatosensation. The current dissertation project examined somatosensory processes among individuals at varying degrees of psychometric risk for psychosis using tactile texture and spatial discrimination and letter recognition tasks. Differential patterns of associations of somatosensory abilities with schizotypal trait dimensions (positive, negative, disorganized), independent of anxiety and depressive symptoms, and the relative contributions of bottom-up (peripheral and morphologic features) versus top-down (error types) processing were examined. It was hypothesized that: 1) performance on somatosensory tasks would account for significant variability in total schizotypal traits; 2) somatosensory performances would be differentially associated with schizotypal trait dimensions, and somatosensory performances would account for variability in schizotypal traits beyond mood symptoms; and, 3) central and peripheral mechanisms may contribute to somatosensory performance, but they were not expected to fully account for the associations between basic somatosensory processing and schizotypal traits. Participants were 125 (37 Male/88 Female) young adults (Mage = 20.55, SD = 3.27) recruited from the City University of New York human subjects pool. Participants were asked to complete somatosensory tasks and mood and personality self-report measures. Fingerprints were obtained to assess morphologic features. Anxiety and depressive symptoms were included as covariates, as they accounted for a significant proportion of variability schizotypal traits. Contrary to hypotheses, after accounting for the relative contributions of mood symptoms, better spatial discrimination and rough texture discrimination abilities were associated with more disorganized and negative schizotypal traits, respectively, at the trend level. Exploratory analyses demonstrated some differential contributions of dermatoglyphic features and letter recognition confusion errors in accounting for variability in schizotypal traits. Specifically, more isomorphic errors were significantly associated with fewer negative (and total) schizotypal traits, and, at trend level, more minutiae were associated with more positive schizotypal traits. Findings are discussed in the context of theories regarding neural substrates of somatosensory processing disruptions in SSDs. Implications for understanding SSD etiology and using somatosensory measures as possible indicators of risk for psychosis are posited.
THE EFFECTS OF CHILDHOOD MALTREATMENT ON CRIMINAL AND SUBSTANCE ABUSE OUTCOMES IN URBAN YOUTH DIAGNOSED WITH ADHD
Virginia De Sanctis
Year of Dissertation:
Results from longitudinal studies of individuals diagnosed with attention-deficit/hyperactive disorder (ADHD) in childhood have clearly shown that these children are at heightened risk for poor outcomes as they enter into adolescence and early adulthood. Among poor outcomes criminality (Barkley, Fischer, Edelbrock, & Smallish, 1990; Hechtman & Weiss, 1986; Mannuzza, Klein, Konig, & Giampino, 1989; Mannuzza, Klein, Bessler, Malloy, & LaPadula, 1993) and substance use disorders (SUDs; Mannuzza, Klein, Bessler, Malloy, & LaPadula, 1998; Wilens, Biederman, & Mick, 1998; King, Iacono, & Mcgue, 2004) are particularly prevalent and cause significant hardship for the individual, their family, and society at large. While early conduct disorder (CD) has been shown to account for a substantial portion of the risk associated with later criminality and substance use in youth with ADHD (Armstrong & Costello, 2002; Brook, Whiteman, Cohen, Shapiro, & Balka, 1995; Disney, Elkins, Mcgue, & Iacono, 1999; Barkley, Fischer, Smallish, & Fletcher, 2004), the extent to which other factors, such as a history of childhood maltreatment, contribute to poor outcomes remain relatively unexplored. This is surprising given the fact that 1) there is a clear literature showing that childhood maltreatment confers considerable risk for later poor outcome in general population studies (Cicchetti & Manly, 2001; Widom, 1989a; Smith & Thornberry, 1995; Zingraff, Leiter, Myers, & Johnsen, 1993; Ireland, Smith, & Thornberry, 2002; Smith, Ireland, & Thornberry, 2005), and 2) children diagnosed with ADHD are at increased risk for maltreatment due to externalizing behaviors and dysfunctional parental relations (Briscoe-Smith & Hinshaw, 2006; Ford, Racusin, Daviss, Ellis,Thomas, Rogers, et al., 1999). To our knowledge, no study has examined the contributory role of childhood maltreatment on later poor outcome among children with ADHD. The identification of maltreatment as risk factor is important as it could 1) significantly change the way clinicians assess and treat children with ADHD, and 2) be instrumental in the development of more targeted treatment alternatives and interventions for this at risk population. The following series of studies investigated the role of childhood maltreatment in the development of later criminality and SUDs in adolescents and young adults in a referred sample of urban, ethnically and socio-economically diverse children recruited in childhood between the ages of seven and 11 years and diagnosed with ADHD (N = 183). This group was re-assessed in adolescence (n = 98), almost ten years later, and compared to a well-matched, never-ADHD comparison group (n = 85). Official criminal records for the sample were obtained approximately three years after commencement of the adolescent follow-up. The results of these studies clearly establish a history of childhood maltreatment as a potent and important risk factor for later poor outcome in ADHD youth. In addition, it appears from our results that at least some portion of the poor outcome that has been attributed to CD in ADHD studies may in fact be due to childhood maltreatment. These findings have important implications with regard to antisocial and substance use outcomes and emphasize the utility of assessing childhood maltreatment in ADHD populations.
Emotion Regulation and Aging: A Neurophysiological Study
Year of Dissertation:
Cognitive emotion regulation (ER) pertains to the ability to change the way we attend to and experience emotional information and events. Older and younger adults, however, differ in the way that they attend to emotional information. Socioemotional Selective Theory (SST) suggests that as we age we become more adept at using cognitive ER strategies to reduce negative emotion because we have less time left in life. As a result of these motivational changes, a branch of SST, the positivity effect, proposes older versus younger adults attend to and remember more pleasant than unpleasant stimuli. Research that systematically examines different types of cognitive ER in controlled (reappraisal) and automatic (directed attention) contexts, using neurophysiological measures, has the potential to clarify the nature of the positivity effect. The present research capitalizes on the excellent temporal resolution of the late positive potential (LPP) which is sensitive to attention to emotion and the use of cognitive ER strategies: increasing emotional responses produces larger LPP amplitudes and decreasing smaller LPP amplitudes. Chapter one served to first evaluate whether cognitive ER impacts memory performance and if the LPP during a cognitive ER task was associated with memory performance in younger adults (N = 49). Subsequent research presented uses the LPP to understand whether younger (n = 49) and older adults (n =28) differ in: a) how they attend to emotional information during a passive viewing task (bottom-up); b) how they use two types of cognitive ER strategies, reappraisal (top-down) and directed attention (intermediary top-down); c) how cognitive ER strategies impact memory performance. Results highlight several important contributions to the cognitive ER and aging literature. First, in the initial study results showed that instructions to increase emotional responses to unpleasant stimuli results in larger LPP amplitudes as compared to viewing or decreasing emotional responses. Memory performance in the increase and view conditions was better than the decrease condition. Additionally, larger LPP amplitudes in the increase and decrease conditions were associated with better memory performance. Second, older adults showed sustained attention to emotional stimuli; however younger and older adults did not show preferential attention to unpleasant and pleasant stimuli (respectively). Third, younger and older adults did not differ in their ability to use reappraisal as measured via the LPP, but did show differences in LPP amplitudes on the directed attention task to unpleasant stimuli. Younger, but not older adults showed larger LPP amplitudes to unpleasant stimuli presented with an arousing versus non-arousing focus. Fourth, age differences in memory performance did not emerge; however stimuli presented with an arousing focus were remembered more than those with a non-arousing focus. Fifth, only larger LPP amplitudes to unpleasant stimuli in the decrease condition (relative to a neutral maintain) were associated with better memory performance for younger and older adults. Taken together results suggest that older versus younger adults may sustain processing of emotional stimuli and that age differences in cognitive ER may lie within bottom-up cognitive ER tasks as opposed to reappraisal. Results hold promise that the LPP may be a useful tool for examining other types of cognitive ER strategies in younger and older adults.
