Description
Most people are experts in some area of information; however, they may not be knowledgeable about other closely related areas. How knowledge is generalized to hierarchically related categories was explored. Past work has found little to no generalization to categories closely related to learned categories. These results do not fit well with other work focusing on attention during and after category learning. The current work attempted to merge these two areas of by creating a category structure with the best chance to detect generalization. Participants learned order level bird categories and family level wading bird categories. Then participants completed multiple measures to test generalization to old wading bird categories, new wading bird categories, owl and raptor categories, and lizard categories. As expected, the generalization measures converged on a single overall pattern of generalization. No generalization was found, except for already learned categories. This pattern fits well with past work on generalization within a hierarchy, but do not fit well with theories of dimensional attention. Reasons why these findings do not match are discussed, as well as directions for future research.

Description
Recognition memory was investigated for naturalistic dynamic scenes. Although visual recognition for static objects and scenes has been investigated previously and found to be extremely robust in terms of fidelity and retention, visual recognition for dynamic scenes has received much less attention. In four experiments, participants view a number of clips from novel films and are then tasked to complete a recognition test containing frames from the previously viewed films and difficult foil frames. Recognition performance is good when foils are taken from other parts of the same film (Experiment 1), but degrades greatly when foils are taken from unseen gaps from within the viewed footage (Experiments 3 and 4). Removing all non-target frames had a serious effect on recognition performance (Experiment 2). Across all experiments, presenting the films as a random series of clips seemed to have no effect on recognition performance. Patterns of accuracy and response latency in Experiments 3 and 4 appear to be a result of a serial-search process. It is concluded that visual representations of dynamic scenes may be stored as units of events, and participant's old

Description
Categories are often defined by rules regarding their features. These rules may be intensely complex yet, despite the complexity of these rules, we are often able to learn them with sufficient practice. A possible explanation for how we arrive at consistent category judgments despite these difficulties would be that we may define these complex categories such as chairs, tables, or stairs by understanding the simpler rules defined by potential interactions with these objects. This concept, called grounding, allows for the learning and transfer of complex categorization rules if said rules are capable of being expressed in a more simple fashion by virtue of meaningful physical interactions. The present experiment tested this hypothesis by having participants engage in either a Rule Based (RB) or Information Integration (II) categorization task with instructions to engage with the stimuli in either a non-interactive or interactive fashion. If participants were capable of grounding the categories, which were defined in the II task with a complex visual rule, to a simpler interactive rule, then participants with interactive instructions should outperform participants with non-interactive instructions. Results indicated that physical interaction with stimuli had a marginally beneficial effect on category learning, but this effect seemed most prevalent in participants were engaged in an II task.

Description
A converging operations approach using response time distribution modeling was adopted to better characterize the cognitive control dynamics underlying ongoing task cost and cue detection in event based prospective memory (PM). In Experiment 1, individual differences analyses revealed that working memory capacity uniquely predicted nonfocal cue detection, while proactive control and inhibition predicted variation in ongoing task cost of the ex-Gaussian parameter associated with continuous monitoring strategies (mu). In Experiments 2A and 2B, quasi-experimental techniques aimed at identifying the role of proactive control abilities in PM monitoring and cue detection suggested that low ability participants may have PM deficits during demanding tasks due to inefficient monitoring strategies, but that emphasizing importance of the intention can increase reliance on more efficacious monitoring strategies that boosts performance (Experiment 2A). Furthermore, high proactive control ability participants are able to efficiently regulate their monitoring strategies under scenarios that do not require costly monitoring for successful cue detection (Experiment 2B). In Experiments 3A and 3B, it was found that proactive control benefited cue detection in interference-rich environments, but the neural correlates of cue detection or intention execution did not differ when engaged in proactive versus reactive control. The results from the current set of studies highlight the importance of response time distribution modeling in understanding PM cost. Additionally, these results have important implications for extant theories of PM and have considerable applied ramifications concerning the cognitive control processes that should be targeted to improve PM abilities.

ABSTRACT
What does it mean to feel an emotion? The nature of emotional
experience has often been described in terms overall conscious experience, termed affect. However, even within affective research there are multiple contradicting theories about the nature and structure of affect. I propose that these contradictions are due to methodological issues in the empirical research examining these underlying dimensions. Furthermore, I propose that subjective emotional experience should be examined separately from overall affect. The current study attempts to address past methodological issues by focusing solely on emotional experiences, developing a comprehensive list of emotion items, and including a broad range of emotional experiences. In Study 1, participants were asked to recall an emotional experience and then report their experience of 76 different emotions during that experience. A factor analysis of the emotion ratings revealed a 5-factor categorical structure with categories of Joy, Anger, Sadness, Fear, and Shame/Jealousy. In Study 2, the 76 emotion words from Study 1 were compared in a semantic space derived from a large collection of text samples in an attempt to compare to the results of Study 1. A semantic space derived from a broad range of texts would reflect relationships of emotional concepts. Study 2 revealed a 1-factor structure, drastically different from the structure in Study 1. The implications from Study 2, however, are limited because of the limited range of literature that was used to create the semantic space in which the words were compared. Overall, the results from these studies suggest that subjective emotional experience should be treated as categorical.

Description
Fibromyalgia (FM) is a chronic musculoskeletal disorder characterized by widespread pain, fatigue, and a variety of other comorbid physiological and psychological characteristics, including a deficit of positive affect. Recently, the focus of research on the pathophysiology of FM has considered the role of a number of genomic variants. In the current manuscript, case-control analyses did not support the hypothesis that FM patients would differ from other chronic pain groups in catechol-O-methyltransferase (COMT) and mu-opioid receptor (OPRM1) genotype. However, evidence is provided in support of the hypothesis that functional single nucleotide polymorphisms on the COMT and OPRM1 genes would be associated with risk and resilience, respectively, in a dual processing model of pain-related positive affective regulation in FM. Forty-six female patients with a physician-confirmed diagnosis of FM completed an electronic diary that included once-daily assessments of positive affect and soft tissue pain. Multilevel modeling yielded a significant gene X environment interaction, such that individuals with met/met genotype on COMT experienced a greater decline in positive affect as daily pain increased than did either val/met or val/val individuals. A gene X environment interaction for OPRM1 also emerged, indicating that individuals with at least one asp allele were more resilient to elevations in daily pain than those homozygous for the asn allele. In sum, the findings offer researchers ample reason to further investigate the contribution of the catecholamine and opioid systems, and their associated genomic variants, to the still poorly understood experience of FM.

Description
In rehabilitation settings, activity limitation can be a significant barrier to recovery. This study sought to examine the effects of state and trait level benefit finding, positive affect, and catastrophizing on activity limitation among individuals with a physician-confirmed diagnosis of either Osteoarthritis (OA), Fibromyalgia (FM), or a dual diagnosis of OA/FM. Participants (106 OA, 53 FM, and 101 OA/FM) who had no diagnosed autoimmune disorder, a pain rating above 20 on a 0-100 scale, and no involvement in litigation regarding their condition were recruited in the Phoenix metropolitan area for inclusion in the current study. After initial questionnaires were completed, participants were trained to complete daily diaries on a laptop computer and instructed to do so a half an hour before bed each night for 30 days. In each diary, participants rated their average daily pain, benefit finding, positive affect, catastrophizing, and activity limitation. A single item, "I thought about some of the good things that have come from living with my pain" was used to examine the broader construct of benefit finding. It was hypothesized that state and trait level benefit finding would have a direct relation with activity limitation and a partially mediated relationship, through positive affect. Multilevel modeling with SAS PROC MIXED revealed that benefit finding was not directly related to activity limitation. Increases in benefit finding were associated, however, with decreases in activity limitation through a significant mediated relationship with positive affect. Individuals who benefit find had a higher level of positive affect which was associated with decreased activity limitation. A suppression effect involving pain and benefit finding at the trait level was also found. Pain appeared to increase the predictive validity of the relation of benefit finding to activity limitation. These findings have important implications for rehabilitation psychologists and should embolden clinicians to encourage patients to increase positive affect by employing active approach-oriented coping strategies like benefit finding to reduce activity limitation.

Description
A cornerstone of children’s socio-cognitive development is understanding that others can have knowledge, thoughts, and perceptions that differ from one’s own. Preschool-aged children often have difficulty with this kind of social understanding, i.e., they lack an explicit theory of mind. The goal of this dissertation was to examine the role mental state language as a developmental mechanism of children’s early understanding of their own mental states (i.e., their introspective ability). Specifically, it was hypothesized that (1) parents’ ability to recognize and appropriately label their children’s mental states and (2) children’s linguistic ability to distinguish between their mental states shapes the development of children’s introspective ability. An initial prediction of the first hypothesis is that parents should recognized differences in the development of children’s self- and other-understanding in order to better help their children’s introspective development. In support of this prediction, parents (N = 400, Mage = 58 months, Range = 28-93 months) reported that children’s understanding of their own knowledge was greater than children’s understanding of others’ knowledge. A prediction of the second hypothesis is that children’s linguistic ability to distinguish between and appropriately label their own mental states should determine their ability to make fined grained judgments of mental states like certainty. In support of this prediction, children’s (N = 197, Mage = 56 months, Range = 36-82 months) ability to distinguish between their own knowledge and ignorance states was associated children’s ability to engage in uncertainty monitoring. Together, these findings provide support for the association between children’s linguistic environment and ability and their introspective development.

Description
In this study, the oppositional processes theory was proposed to suggest that reliance on semantic and episodic memory systems hinder originality during idea generation for divergent thinking tasks that are generally used to assess creative potential. In order to investigate the proposed oppositional processes theory, three experiments that manipulated the memory accessibility in participants during the alternative uses tasks were conducted. Experiment 1 directly instructed participants to either generate usages based on memory or not from memory; Experiment 2 provided participants with object cues that were either very common or very rare in daily life (i.e., bottle vs. canteen); Experiment 3 replicated the same manipulation from Experiment 2 with much longer generation time (10 minutes in Experiment 2 vs. 30 minutes in Experiment 3). The oppositional processes theory predicted that participants who had less access to direct and unaltered usages (i.e., told to not use memory, were given rare cues, or were outputting items later in the generation period) during the task would be more creative. Results generally supported the predictions in Experiments 1 and 2 where participants from conditions which limited their access to memory generated more novel usages that were considered more creative by independent coders. Such effects were less prominent in Experiment 3 with extended generation time but the trends remained the same.

Description
Purpose: The purpose of this study was to evaluate the efficacy of the EMBRACE Spanish support intervention for at-risk dual language learners and to determine which verbal and nonverbal characteristics of students were related to benefit from the intervention. The first study examined oral language and reading characteristics and the second study examined motor characteristics in predicting the children's outcomes on a reading comprehension intervention.
Method: Fifty-six participants in 2nd-5th grade were randomly assigned to one of two groups: 1) Spanish-support intervention, or 2) Spanish-support control. Outcome measures included performance on comprehension questions related to intervention texts, questions on the final narrative and expository text without strategy instruction, and difference scores on alternate forms of the Gates-MacGinitie (GMRT-4, MacGinitie, MacGinitie, Maria, & Dreyer, 2002) reading comprehension subtest administered pre- post-intervention. Multi-level hierarchical linear models were used to account for nesting of question within child within classroom. Regression models were used to examine the power of motor predictors in predicting Spanish and English language performance.
Results: Results from study 1 indicated that the intervention was most effective for narrative (vs. expository) texts and easy (vs. more difficult) texts. Dual language learners (DLLs) with lower initial English reading comprehension abilities benefitted more from the intervention than those with stronger reading skills. Results from Study 2 indicated that oral fine motor abilities predicted Spanish (but not English) oral language abilities in the expected direction (i.e. faster performance associated with higher language scores). The speed of /pata/ productions predicted reading comprehension during the intervention, but not in the expected direction (i.e. slower speeds associated with higher accuracy). Manual fine motor performance on tapping tasks was not related to language or reading.
Conclusions: The EMBRACE intervention has promise for use with at-risk DLLs. Future research should take care to match text difficulty with child skills so as to maximize benefit from the intervention. Oral fine motor abilities were related to language abilities in DLLs, but only for the native language. Slower oral fine motor performance predicted higher accuracy on intervention questions, suggesting that EMBRACE may be particularly effective for children with weak fine motor skills.
