Age-related differences in guessing on free and forced recall tests

This study examined possible age-related differences in recall, guessing, and metacognition on free recall tests and forced recall tests. Participants studied categorised and unrelated word lists and were asked to recall the items under one of the following test conditions: standard free recall, free recall with a penalty for guessing, free recall with no penalty for guessing, or forced recall. The results demonstrated interesting age differences regarding the impact of liberal test instructions (i.e., forced recall and no penalty) relative to more conservative test instructions (i.e., standard free recall and penalty) on memory performance. Specifically, once guessing was controlled, younger adults' recall of categorised lists varied in accordance with test instructions while older adults' recall of categorised lists did not differ between conservative and liberal test instructions, presumably because older adults approach standard free recall tests of categorised lists with a greater propensity towards guessing than young adults.     

Normative MMPI-2 Profiles of Christian Counseling Students: An Investigation of Subculture in Standardized Testing

This research sought to explore whether a normative profile on the MMPI-2 emerged for counseling students in a counselor training program at a seminary in the Midwest and the extent to which this profile compares to those proposed for counseling students or those preparing for pastoral ministry. Normative profiles of master’s level counseling students were compared to profiles of similar samples. Findings indicated that profiles of the current student sample are similar to those of other religious students. Implications of these findings are explored regarding the use of the MMPI-2 with counseling students who are members of the Christian subculture.     

Bayesian analogy with relational transformations

How can humans acquire relational representations that enable analogical inference and other forms of high-level reasoning? Using comparative relations as a model domain, we explore the possibility that bottom-up learning mechanisms applied to objects coded as feature vectors can yield representations of relations sufficient to solve analogy problems. We introduce Bayesian analogy with relational transformations (BART) and apply the model to the task of learning first-order comparative relations (e.g., larger, smaller, fiercer, meeker) from a set of animal pairs. Inputs are coded by vectors of continuous-valued features, based either on human magnitude ratings, normed feature ratings (De Deyne et al., 2008), or outputs of the topics model (Griffiths, Steyvers, & Tenenbaum, 2007). Bootstrapping from empirical priors, the model is able to induce first-order relations represented as probabilistic weight distributions, even when given positive examples only. These learned representations allow classification of novel instantiations of the relations and yield a symbolic distance effect of the sort obtained with both humans and other primates. BART then transforms its learned weight distributions by importance-guided mapping, thereby placing distinct dimensions into correspondence. These transformed representations allow BART to reliably solve 4-term analogies (e.g., larger:smaller::fiercer:meeker), a type of reasoning that is arguably specific to humans. Our results provide a proof-of-concept that structured analogies can be solved with representations induced from unstructured feature vectors by mechanisms that operate in a largely bottom-up fashion. We discuss potential implications for algorithmic and neural models of relational thinking, as well as for the evolution of abstract thought.     

Introduction to the special section on the neural substrate of analogical reasoning and metaphor comprehension

The special section on the neural substrate of relational reasoning includes 4 articles that address the processes and brain regions involved in analogical reasoning (Green, Kraemer, Fugelsang, Gray, & Dunbar, 2011; Maguire, McClelland, Donovan, Tillman, & Krawczyk, 2011) and in metaphor comprehension (Chettih, Durgin, & Grodner, 2011; Prat, Mason, & Just, 2011). We see this work as an example of how neuroscience approaches to cognition can lead to increased understanding of cognitive processes. In this brief introduction, we first situate the 4 articles in the context of prior cognitive neuroscience work on relational reasoning. We then highlight the main issues explored in these articles: different sources of complexity and difficulty in relational processing, potential differences between the roles of the 2 hemispheres, and the impact of individual differences in various cognitive abilities. The 4 articles illustrate a range of methodologies, including functional magnetic resonance imaging (fMRI; Green et al., 2011; Prat et al., 2011), event-related potentials (ERPs; Maguire et al., 2011), and different types of semantic priming (Chettih et al., 2011; Prat et al., 2011). They highlight the connections between research on analogy and on metaphor comprehension and suggest, collectively, that a cognitive neuroscience approach to relational reasoning can lead to converging conclusions.     

Obstacles to research in residential juvenile justice facilities: recommendations for researchers

Federal, state, and local initiatives to improve the treatment and outcomes for young people in the juvenile justice system prompt the need for additional research. Despite the call for empirical data, researchers encounter numerous obstacles when initiating and conducting studies in detention and post-adjudication facilities. These obstacles are often only briefly mentioned in publications, but they can interfere with researchers' desires and abilities to conduct studies in these settings. This paper reviews legal, ethical, and methodological challenges to successfully conducting research in detention and residential post-adjudication placements, including selecting and accessing appropriate facilities, obtaining institutional review board approval, seeking parental permission and youth assent, reporting child abuse and neglect, responding to participants' threats to harm self or others, working effectively with facilities, juvenile justice system-related attrition, and the dissemination of research findings. Recommendations are presented to help investigators anticipate obstacles when designing and executing research protocols to prevent interference and to encourage ethical responses and successful study completion.     

An Inkblot for the Implicit Assessment of Personality: The Semantic Misattribution Procedure

Misattributions people make about their own reaction to ambiguous stimuli can be used to measure personality self‐concepts implicitly. On the basis of a semantic misattribution priming paradigm [semantic misattribution procedure (SMP)], we assessed the implicit personality self‐concept related to three dimensions included in the Big‐Five model: conscientiousness, neuroticism, and extraversion. Across three studies (N1 = 98, N2 = 140, and N3 = 135), the SMP was robustly related, in the expected direction, to individual differences in self‐reported personality questionnaires and managed to predict both self‐reported and objectively measured behaviours. The main advantage of SMP over classical explicit measures of personality is its higher resistance to social desirability tendencies, although its psychometric properties are somewhat lower than those pertaining to explicit measures of personality. Finally, comparisons of our results with studies that used other implicit measures of personality self‐concept indicate that the SMP has higher criterion validity.

Executive functioning and psychological adjustment in children and youth with spina bifida

Children and adolescents with spina bifida are at risk for poor neuropsychological functioning and psychological outcomes. The relationship between executive functioning and psychological adjustment is an area worthy of investigation in this population. The current study assessed executive functioning and psychological outcomes in a group of children and adolescents with spina bifida (SBM) (n = 51) and nondisabled controls (n = 45). A mediation model was hypothesized, such that Metacognition, as measured by the Behavior Rating Inventory of Executive Function (BRIEF), mediated the relationship between group status (spina bifida versus nondisabled controls) and psychological outcomes. Results indicated that metacognitive skills fully explained the relationship between group and internalizing and depressive symptoms as reported by mothers. In particular, specific components of the BRIEF Metacognition composite were most responsible for this relationship, including Initiate, Working Memory, and Plan/Organize. The study limitations include its cross-sectional nature that precludes drawing conclusions about causality. The results have implications for treatment interventions for children and adolescents with spina bifida and typically developing individuals.     

The cost of callousness: regulating compassion influences the moral self-concept

It has often been argued that compassion is fundamental to morality. Yet people often suppress compassion for self-interested reasons. We provide evidence that suppressing compassion is not cost free, as it creates dissonance between a person's moral identity and his or her moral principles. We instructed separate groups of participants to regulate their compassion, regulate their feelings of distress, or freely experience emotions toward compassion--inducing images. Participants then reported how central morality was to their identities and how much they believed that moral rules should always be followed. Participants who regulated compassion-but not those who regulated distress or experienced emotions--showed a dissonance-based trade-off. If they reported higher levels of moral identity, they had a greater belief that moral rules could be broken. If they maintained their belief that moral rules should always be followed, they sacrificed their moral identity. Regulating compassion thus has a cost of its own: It forces trade-offs within a person's moral self-concept.     

Neuropsychological Sequelae of PTSD and TBI Following War Deployment among OEF/OIF Veterans

Posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) are highly prevalent among Veterans of the conflicts in Iraq and Afghanistan. These conditions are associated with common and unique neuropsychological and neuroanatomical changes. This review synthesizes neuropsychological and neuroimaging studies for both of these disorders and studies examining their co-occurrence. Recommendations for future research, including use of combined neuropsychological and advanced neuroimaging techniques to study these disorders alone and in concert, are presented. It is clear from the dearth of literature that addiitonal studies are required to examine and understand the impact of specific factors on neurocognitive outcome. Of particular relevance are temporal relationships between PTSD and mTBI, risk and resilience factors associated with both disorders and their co-occurrence, and mTBI-specific factors such as time since injury and severity of injury, utilizing comprehensive, yet targeted cognitive tasks.     

Comma N' cents in pricing: The effects of auditory representation encoding on price magnitude perceptions

Numbers and prices can be processed and encoded in three different forms: 1) visual [based on their written form in Arabic numerals (e.g., 72)], 2) verbal [based on spoken word-sounds (e.g., “seventy” and “two”), and 3) analog (based on judgments of relative “size” or amount (e.g., more than 70 but less than 80)]. In this paper, we demonstrate that including commas (e.g., $1599 vs. $1599) and cents (e.g., $1599.85 vs. $1599) in a price's Arabic written form (i.e., how it is perceived visually) can change how the price is encoded and represented verbally in a consumer's memory. In turn, the verbal encoding of a written price can influence assessments of the numerical magnitude of the price. These effects occur because consumers non-consciously perceive that there is a positive relationship between syllabic length and numerical magnitude. Three experiments are presented demonstrating this important effect.
