Description
The purpose of this study was to investigate the effect of partial exemplar experience on category formation and use. Participants had either complete or limited access to the three dimensions that defined categories by dimensions within different modalities. The concept of "crucial dimension" was introduced and the role it plays in category definition was explained. It was hypothesized that the effects of partial experience are not explained by a shifting of attention between dimensions (Taylor & Ross, 2009) but rather by an increased reliance on prototypical values used to fill in missing information during incomplete experiences. Results indicated that participants (1) do not fill in missing information with prototypical values, (2) integrate information less efficiently between different modalities than within a single modality, and (3) have difficulty learning only when partial experience prevents access to diagnostic information.

Description
Intuitive decision making refers to decision making based on situational pattern recognition, which happens without deliberation. It is a fast and effortless process that occurs without complete awareness. Moreover, it is believed that implicit learning is one means by which a foundation for intuitive decision making is developed. Accordingly, the present study investigated several factors that affect implicit learning and the development of intuitive decision making in a simulated real-world environment: (1) simple versus complex situational patterns; (2) the diversity of the patterns to which an individual is exposed; (3) the underlying mechanisms. The results showed that simple patterns led to higher levels of implicit learning and intuitive decision-making accuracy than complex patterns; increased diversity enhanced implicit learning and intuitive decision-making accuracy; and an embodied mechanism, labeling, contributes to the development of intuitive decision making in a simulated real-world environment. The results suggest that simulated real-world environments can provide the basis for training intuitive decision making, that diversity is influential in the process of training intuitive decision making, and that labeling contributes to the development of intuitive decision making. These results are interpreted in the context of applied situations such as military applications involving remotely piloted aircraft.

Description
Over recent decades, euthanasia has been a topic of increasing debate. With legalization of euthanasia in the states of Oregon and Washington and attempted reform in several other U.S. states and nations worldwide, it has become increasingly important to understand the roles and values of helping professionals who might be working with clients considering this option. The current study targeted 85 undergraduate students, 54 doctoral students in counseling psychology, and 53 doctoral-level professionals in psychology to assess both their personal values regarding euthanasia and their willingness to allow a client the autonomy to make a decision about euthanasia. Several factors were analyzed in regards to their relation to client autonomy and attitudes toward euthanasia, including age of client and sex of client. These variables were manipulated in vignettes to create four scenarios: a 24 year old male, 24 year old female, 80 year old male, 80 year old female. Other factors included level of education of the participant, spirituality and strength of religiosity of the participant, and personal experiences with deaths of friends or family members. Results indicated that more education was associated with greater support for euthanasia and that stronger religiosity and spirituality were related to less support for euthanasia. This study also found that participants did not exhibit differential levels of support based solely on the age or the sex of the client depicted in the vignette. Results further indicated that for doctoral students and professionals the loss of a loved one, regardless of cause of death, did not have a significant effect on their attitudes toward euthanasia. It is important for training programs to be aware of these findings in order to monitor trainees in terms of personal biases in the therapy relationship. With objectivity a high priority while working with clients, it is necessary to be aware of outside factors potentially influencing one's work with clients surrounding this value-laden issue.

Description
This study examined four research questions investigating relationships among the experience of trauma, identity development, distress, and positive change. There were 908 participants in the study, ranging in age from 18 to 24 which is known as the period of emerging adulthood. Participants completed an online survey regarding their exposure to trauma and reactions to these experiences. The first research question examined the experience of trauma for the sample. The second question examined group differences among the participant's identity status, gender, and posttraumatic stress disorder (PTSD) diagnostic status on the hypothesized variables. In general, comparisons among the four identity status groups found participants who experienced greater identity exploration (diffused and moratorium) experienced more distress, whereas the identity status groups that reported greater identity commitments (foreclosed and achieved) were associated with positive change. Similar findings were found for PTSD diagnostic status indicating more distress and identity exploration for participants with the diagnosis and more positive change and identity commitments for participants without the diagnosis. Female participants were found to experience more PTS symptoms, centrality of the trauma event, and positive growth than males. Examination of the relationships between trauma severity and posttraumatic growth revealed an inverted U-shaped relationship (quadratic) that was a significant improvement from the linear model. An S-shaped relationship (cubic) was found for the relationship between trauma exposure and posttraumatic growth. Regression analyses found the centrality of the trauma event to one's identity predicted identity distress above and beyond the experience of trauma. In addition, identity distress and the centrality of the trauma contributed to the variance for identity exploration, while only identity distress contributed to identity commitments. Finally, identity development significantly predicted positive change above and beyond, identity distress, centrality of the trauma event, and the experience of trauma. Collectively, these results found both distress and growth to be related to the experience of trauma. Distress within one's identity can contribute to difficulties in the psychosocial stage of identity development among emerging adults. However, the resolution of identity exploration towards commitments to goals, roles, and beliefs, can help trauma survivors experience resilience and growth after stressful experiences.

Description
This study explored the motivation and persistence factors for non-professional athletes who decided after the age of 40 to begin training for an IRONMAN distance triathlon. The qualitative methodology of grounded theory (Strauss & Corbin, 1998) was used in conceptualizing and implementing the research. In-depth interviews were conducted with 10 individuals in the Southwest region of the United States. Data was coded in accordance with grounded theory methods. Motivation themes that emerged from the data centered around either initiating training for triathlon as an approach toward a specific goal or outcome, or beginning triathlon as a way to cope with personal difficulties. Obstacles to motivation also emerged, such as finances and time, injury, fear and doubt, and interpersonal difficulties. Persistence themes emerged that centered around either taking active steps to help continue training and relying on internal traits or characteristics to promote persistence. Data are discussed in terms of how these individuals adopt triathlon as a part of their lifestyle and identity, and how they come to persist in training beyond IRONMAN.

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
The purpose of this paper is to review the literature on interventions for children with conduct disorder. Conduct disorder mainly effects children and adolescents, and is characterized as a pattern of persistent (sometimes anti-social) behavior in which an individual violates the basic rights of others or disregards societal norms and rules. If left untreated, conduct disorder can be a precursor to more severe behavioral problems and consequences, including juvenile delinquency and unlawful behavior as an adult. The interventions reviewed in this paper include cognitive-behavioral therapy (CBT), supportive counseling, experiential therapy, multisystemic therapy (MST), parent management training (PMT), military school, scared-straight programs and boot camps, and medication. Based on empirical data and recommendations from experts in the field, I conclude with suggestions for parents on how best to help their children diagnosed with conduct disorder.

Description
Anorexia Nervosa is an increasing problem in today's day and age. With the overbearing messages of what the media portrays to be beautiful, some people are responding by engaging in unhealthy eating habits. By taking embodied cognition into consideration, there may be a method to help treat people with Anorexia Nervosa that has not been attempted yet. According to embodied cognition, the body influences the way a person thinks (Glenberg, 2010). If people with Anorexia Nervosa are thinking in unhealthy ways in terms of their body, providing relief from these unhealthy forms of thinking may come in the form of using a surrogate body: a virtual avatar in a video game. Through explanation and integration of the Embodied Social Presence Theory, the use of a virtual avatar as a surrogate body for victims of Anorexia Nervosa becomes a probable and viable method of ushering treatment. The avatars are not an explicit treatment of Anorexia Nervosa, but rather a way to allow actual treatment and therapy to be more successful.

Description
Introspective awareness refers to direct access to one’s own internal and subjective thoughts and feelings (Wimmer & Hartl, 1991). Two theories, simulation theory and theory-theory, have been used to understand our access to our mental states. Simulation theory (Harris, 1991) involves imagining yourself in another person’s situation, reading off of your mental state, and attributing that state to the other person. Theory-theory (Gopnik, 1993) involves an interrelated body of knowledge, based on core mental-state constructs, including beliefs and desires, that may be applied to everyone—self and others (Gopnik & Wellman, 1994). Introspection is taken for granted by simulation theory, and explicitly denied by theory-theory. This study is designed to test for evidence of introspection in young children using simple perception and knowledge task. The current evidence is against introspective awareness in children because the data suggest that children cannot report their own false beliefs and they cannot report their on-going thoughts (Flavell, Green & Flavell, 1993; Gopnik & Astington, 1988). The hypothesis in this study states that children will perform better on Self tasks compared to Other tasks, which will be evidence for introspection. The Other-Perception tasks require children to calculate the other’s line of sight and determine if there is something obscuring his or her vision. The Other-Knowledge tasks require children to reason that the other’s previous looking inside a box means that he or she will know what is inside the box when it is closed. The corresponding Self tasks could be answered either by using the same reasoning for the self or by introspection to determine what it is they see and do not see, and know and do not know. Children performing better on Self tasks compared to Other tasks will be an indication of introspection. Tests included Yes/No and Forced Choice questions, which was initially to ensure that the results will not be caused by a feature of a single method of questioning. I realized belatedly, however, that Forced Choice was not a valid measure of introspection as children could introspect in both the Self and Other conditions. I also expect to replicate previous findings that reasoning about Perception is easier for children than reasoning about Knowledge.

Description
Humans require sufficient social understanding and connectedness to thrive (Baumeister & Leary, 1995). The current study evaluates the effectiveness of the Social Intelligence Institute's training program pilot. At a middle school in Phoenix, Arizona, students in a 7th and 8th grade class participated in this pilot program during the spring of 2013. Pre- and post-test questionnaires administered indicated changes in participants reported measures of Perspective Taking, Empathetic Concern, Interpersonal Expectations, and Relationship Self-Efficacy. The program consists of seven modules, each with several sessions, including instructional videos with reflection questions and class discussions. It was predicted that there would be a significant increase in mean scores for the dependent variables in the questionnaire mentioned above from the pre-test to the post-test. However, the null hypotheses were not rejected; statistical significance in t-tests of the measured variables were not met. Yet, the program was more effective for 8th graders than for 7th graders for Perspective Taking. This study of the SI pilot program demonstrates areas of improvement and provides support for wider implementation in the future.
