The influence of depression symptoms on exploratory decision-making

People with symptoms of depression show impairments in decision-making. One explanation is that they have difficulty maintaining rich representations of the task environment. We test this hypothesis in the context of exploratory choice. We analyze depressive and non-depressive participants’ exploration strategies by comparing their choices to two computational models: (1) an “Ideal Actor” model that reflectively updates beliefs and plans ahead, employing a rich representation of the environment and (2) a “Naïve Reinforcement Learning” (RL) model that updates beliefs reflexively utilizing a minimal task representation. Relative to non-depressive participants, we find that depressive participants’ choices are better described by the simple RL model. Further, depressive participants were more exploratory than non-depressives in their decision-making. Depressive symptoms appear to influence basic mechanisms supporting choice behavior by reducing use of rich task representations and hindering performance during exploratory decision-making.     

Spouse and Family Functioning Before and After a Marine’s Suicide: Comparisons to Deaths by Accident and in Combat

The impact of service member suicides on families is not well understood. Civilian studies have demonstrated that family survivors of suicide deaths experience complicated grief, feel guilt and shame, and often do not receive sufficient social support. In this exploratory study, spouse survivors of Marines who died by suicide (N = 17), accident (N = 19), and in combat (N = 34) retrospectively reported on their immediate pre- and postmortem and current personal and family functioning. Nonparametric analyses revealed that several between-group differences existed. Observation of the means suggested that the spouses and families of Marines who died by suicide exhibited significantly poorer pre- and postmortem functioning compared with those whose spouses died in combat. Specific challenges included low family cohesion, high family conflict, perceived stigma, and shame. There were no differences in current spouse or family functioning, and there was weak evidence for posttraumatic growth among surviving spouses of those dying by suicide. These results should be considered preliminary and interpreted with caution given several methodological challenges.     

Hegelian madness? Nikolaj Fëdorov’s repudiation of history

Nikolaj Fëdorov insists that the proper end of the philosophical project must be the repudiation of history in the creation of a new being not subject to death. This project appears to be an extension of the kind of philosophical madness one might associate with the Platonic striving for synoptic vision of the whole. Federov develops this notion of philosophy, not in dialogue with Plato, however, as much as with the Hegelian notion of the end of human striving in absolute knowledge, the final unity of will and reason, which Fëdorov criticizes. The exceptional radicality of Fëdorov’s philosophical project as a project of divinization, as well as its flaws, are most clearly manifest in the Russian context with reference to two other crucial projects of divinization deeply influenced by Hegel: that of Vladimir Solov’ëv and Alexandre Kojève.     

Learning and retention through predictive inference and classification

Work in category learning addresses how humans acquire knowledge and, thus, should inform classroom practices. In two experiments, we apply and evaluate intuitions garnered from laboratory-based research in category learning to learning tasks situated in an educational context. In Experiment 1, learning through predictive inference and classification were compared for fifth-grade students using class-related materials. Making inferences about properties of category members and receiving feedback led to the acquisition of both queried (i.e., tested) properties and nonqueried properties that were correlated with a queried property (e.g., even if not queried, students learned about a species' habitat because it correlated with a queried property, like the species' size). In contrast, classifying items according to their species and receiving feedback led to knowledge of only the property most diagnostic of category membership. After multiple-day delay, the fifth-graders who learned through inference selectively retained information about the queried properties, and the fifth-graders who learned through classification retained information about the diagnostic property, indicating a role for explicit evaluation in establishing memories. Overall, inference learning resulted in fewer errors, better retention, and more liking of the categories than did classification learning. Experiment 2 revealed that querying a property only a few times was enough to manifest the full benefits of inference learning in undergraduate students. These results suggest that classroom teaching should emphasize reasoning from the category to multiple properties rather than from a set of properties to the category.     

Exploring the Relationship Between Gay Affirmative Practice and Empathy Among Mental Health Professionals

During the last several decades, psychologists have placed emphasis on multicultural competence as an essential aspect of training and practice. However, despite this emphasis, empirical data on the effects of multicultural training and practice are generally limited to variables such as race and ethnicity, with very little research on sexual minorities. However, a framework for understanding competent practice with sexual minorities does exist in the form of the concept of gay affirmative practice (GAP), which has been successfully operationalized by Crisp ( 2006b ). Using the GAP measure and scores of empathy, the authors examined students and practitioners in the helping profession to explore the relationship between empathy and level of gay affirmative work. Findings indicated that levels of empathy predicted overall levels of GAP. The authors discuss the clinical implications of these findings and explore how the findings fit within the literature surrounding empathic understanding. Durante las últimas décadas, los psicólogos han puesto un énfasis especial en la competencia multicultural como un aspecto esencial en la formación y la práctica. Sin embargo, a pesar de este énfasis, los datos empíricos sobre los efectos de la formación multicultural y su práctica están generalmente limitados a variables como raza y etnicidad, con escasas investigaciones realizadas sobre minorías sexuales. Aun así, existe un marco teórico para comprender la práctica competente con minorías sexuales denominado terapia afirmativa gay (GAP, por sus siglas en inglés), que fue operacionalizado con éxito por Crisp ( 2006b ). Usando las medidas GAP y puntuaciones de empatía, los autores examinaron a estudiantes y profesionales del campo de la consejería para explorar la relación entre empatía y el nivel de trabajo afirmativo con la comunidad gay. Los resultados indicaron que los niveles de empatía pronosticaron niveles totales de GAP. Los autores discuten las implicaciones clínicas de estos resultados y exploran cómo estos encajan con la literatura sobre comprensión empática.     

Environment and Goals Jointly Direct Category Acquisition

Abstract— Developing categorization schemes involves discovering structures in the world that support a learner's goals. Existing models of category learning, such as exemplar and prototype models, neglect the role of goals in shaping conceptual organization. Here, a clustering approach is discussed that reflects the joint influences of the environment and goals in directing category acquisition. Clusters are a flexible representational medium that exhibits properties of exemplar, prototype, and rule-based models. Clusters reflect the natural bundles of correlated features present in our environment. The clustering model Supervised and Unsupervised Stratified Incremental Adaptive Network (SUSTAIN) operates by assuming the world has a simple structure and adding complexity (i.e., clusters) when existing clusters fail to satisfy the learner's goals and thus elicit surprise. Although simple, this operation is sufficient to address findings from numerous laboratory and cross-cultural categorization studies.     

Antecedents and consequences of autonomy- and dependency-oriented help toward refugees

We tested antecedents (paternalistic beliefs; Study 1) and consequences (social change potential; Study 2) of autonomy- and dependency-oriented help and developed scales assessing paternalistic beliefs and both forms of help. In Study 1 (N = 143 Germans), we focused on paternalistic beliefs as an antagonist to social change and a key distinguishing variable between engagement in both forms of help. As expected, paternalistic beliefs were positively related to dependency-oriented help, mediated by concern for a positive national moral image, but negatively related to autonomy-oriented help, mediated by perceived competence of refugees. In Study 2, both refugees (N = 80) and Germans (N = 94) perceived autonomy-oriented help to have more potential for social change than dependency-oriented help.     

The organization of words and environmental sounds in the second year: Behavioral and electrophysiological evidence

The majority of research examining early auditory‐semantic processing and organization is based on studies of meaningful relations between words and referents. However, a thorough investigation into the fundamental relation between acoustic signals and meaning requires an understanding of how meaning is associated with both lexical and non‐lexical sounds. Indeed, it is unknown how meaningful auditory information that is not lexical (e.g., environmental sounds) is processed and organized in the young brain. To capture the structure of semantic organization for words and environmental sounds, we record event‐related potentials as 20‐month‐olds view images of common nouns (e.g., dog) while hearing words or environmental sounds that match the picture (e.g., “dog” or barking), that are within‐category violations (e.g., “cat” or meowing), or that are between‐category violations (e.g., “pen” or scribbling). Results show both words and environmental sounds exhibit larger negative amplitudes to between‐category violations relative to matches. Unlike words, which show a greater negative response early and consistently to within‐category violations, such an effect for environmental sounds occurs late in semantic processing. Thus, as in adults, the young brain represents semantic relations between words and between environmental sounds, though it more readily differentiates semantically similar words compared to environmental sounds.     

On the categorization of aphasic typologies: the SOAP (a test of syntactic complexity)

This paper presents a new measure of syntactic comprehension abilities in brain-damaged populations known as the SOAP (Subject-relative, Object-relative, Active, and Passive), along with data supporting its sensitivity and specificity. This assessment tool examines comprehension of sentences (matched for length) of four syntactic construction types: active, passive, subject-relative, and object-relative. Data are presented that indicate that the SOAP provides a sensitive and reliable differentiation of aphasia subgroups. The SOAP's sensitivity in differentiating broad behavioral (anterior/posterior-lesioned) groups is compared to the auditory comprehension component of the Boston Diagnostic Aphasia Examination (BDAE), supporting its sensitivity differentiating between anterior- and posterior-lesioned groups. It is argued that this tool can be an important accompaniment to standard aphasia assessment batteries in more sensitively defining syntactic comprehension deficits.     

Metacognitions in Triathletes: Associations With Attention,State Anxiety,and Relative Performance

This study investigated how metacognitive beliefs in triathletes covary with state anxiety dimensions, prior to competition. It also examined how metacognitions relate to concentration, after controlling for state anxiety. Regression analyses revealed that specific metacognitive beliefs were differentially predictive of state anxiety dimensions and concentration. When accounting for the state anxiety variables in a hierarchical model predicting concentration, positive beliefs about worry, negative beliefs about worry, and cognitive anxiety remained as significant predictors. Metacognitive beliefs were also found to differ across time-to-event intervals. Overall, the results demonstrated that a metacognitive framework is a viable pathway for future sporting research.
