The Deep Self Model and asymmetries in folk judgments about intentional action

Recent studies by experimental philosophers demonstrate puzzling asymmetries in people’s judgments about intentional action, leading many philosophers to propose that normative factors are inappropriately influencing intentionality judgments. In this paper, I present and defend the Deep Self Model of judgments about intentional action that provides a quite different explanation for these judgment asymmetries. The Deep Self Model is based on the idea that people make an intuitive distinction between two parts of an agent’s psychology, an Acting Self that contains the desires, means-end beliefs, and intentions that are the immediate causal source of an agent’s actions, and a Deep Self, which contains an agent’s stable and central psychological attitudes, including the agent’s values, principles, life goals, and other more fundamental attitudes. The Deep Self Model proposes that when people are asked to make judgments about whether an agent brought about an outcome intentionally, in addition to standard criteria proposed in traditional models, people also assess an additional ‘Concordance Criterion’: Does the outcome concord with the psychological attitudes of the agent’s Deep Self? I show that the Deep Self Model can explain a very complex pattern of judgment asymmetries documented in the experimental philosophy literature, and does so in a way that has significant advantages over competing models.     

Latent inhibition in the honey bee, Apis mellifera: Is it a unitary phenomenon?

Latent inhibition refers to learning that some stimuli are not signals of important events. It has been widely studied in vertebrates, but it has been substantially less well studied in invertebrates. We present an investigation into latent inhibition in the honey bee (Apis mellifera) using a proboscis extension response conditioning procedure that involved ‘preexposure’ of an odor without reinforcement prior to appetitive conditioning. A significant latent inhibition effect, measured in terms of a reduction in acquisition performance to the preexposed odor, was observed after 8 unreinforced presentations, and the effect continued to increase in strength up to 30 presentations. We also observed that memories formed for the preexposed odor lasted at least 24 h. Further manipulation of interstimulus interval and the visual conditioning context partially attenuated the effect. The latter results indicate that latent inhibition in honey bees may not be a unitary phenomenon. Two different mechanisms may be required, in which one mechanism is dependent on the visual context and the second is not.     

The Nuts and Bolts of Behavioral Observation of Marital and Family Interaction

Despite considerable discussion in the literature about the advantages of observational research and the relative benefits of different coding systems and strategies, little is written about the actual implementation of this assessment strategy. This paper presents an overall framework as well as the essential components involved in collecting (selection of task, setting, unit of analysis, and coding system) and coding (transcribing, selecting and training coders, transforming data, and analyzing reliability) of observational data. To achieve success with observational methods, we emphasize several issues, including (a) the research question as the motivator for all decisions, (b) the interrelatedness of tasks, and (c) the implications of decisions early in the process for later stages of analysis and interpretation. Investigators are encouraged to communicate the details of their observational and coding procedures so that these methods are readily accessible for purposes of replication and comparison.     

High-pressure electrical resistivity behaviour of nanocrystalline perovskite (La,Sr)(Mn,Fe)O3

We report here the electrical resistivity of nanocrystalline perovskite-structured La–Sr manganites as a function of pressures up to 8?GPa, at room temperature. The nanocrystalline perovskite manganites were prepared by the sol–gel technique and found to have crystallite sizes of 12–18?nm. The pressure dependence of the electrical resistivity shows a first-order phase transition at 0.66(2)?GPa and a subtle phase transition between 3.5 and 3.8?GPa. The first-order transition at 0.66?GPa can be related to the transition from localized-electron to band magnetism.     

Individual‐Oriented Relationship Education: An Evaluation Study in Community‐Based Settings

The effects of relationship education aimed at individuals, rather than couples, have not yet been widely investigated. However, increasingly, relationship education is provided to large and diverse groups of individuals who may be in varying stages of relationships. Several programs have been developed to strengthen relationship competencies among single individuals as well as among partnered individuals who, for a variety of reasons, seek relationship education without their partners. The current study is an exploratory evaluation study that examined self‐reported outcomes for 706 single and partnered individuals who attended Within My Reach classes delivered in community‐based agencies. Participants were from diverse backgrounds and exhibited many of the risk factors for poor relationship outcomes including unemployment, low income, and childhood experience of abuse or neglect. Pre‐post analyses indicated that the program was beneficial for both singles and partnered individuals. Singles reported increased belief in ability to obtain healthy relationships. Partnered individuals reported increased relationship quality, relationship confidence, and reduced conflict. Regardless of relationship status, participants also reported improvement in general relationship and communication skill. Results support the utility of individual‐oriented relationship education for singles and partnered individuals with diverse background characteristics.     

Structural stability of W2B5 under high pressure

High-pressure structural stability studies have been carried out on tungsten boride W₂B₅ up to maximum pressure of 36 GPa using a Mao-Bell diamond-anvil cell at beamline BR-12 of the ELETTRA synchrotron facility (λ = 0.68881 Å). The hexagonal phase (S.G:P6₃/mmc) of W₂B₅ is stable up to the maximum pressure studied. The bulk modulus is estimated to be ~347 GPa using the Birch–Murnaghan equation of state. The variation of lattice parameters and bond lengths B–B and W–B have been studied and the c-axis is seen to be marginally more compressible than the a-axis.

Words can slow down category learning

Words have been shown to influence many cognitive tasks, including category learning. Most demonstrations of these effects have focused on instances in which words facilitate performance. One possibility is that words augment representations, predicting an across the-board benefit of words during category learning. We propose that words shift attention to dimensions that have been historically predictive in similar contexts. Under this account, there should be cases in which words are detrimental to performance. The results from two experiments show that words impair learning of object categories under some conditions. Experiment 1 shows that words hurt performance when learning to categorize by texture. Experiment 2 shows that words also hurt when learning to categorize by brightness, leading to selectively attending to shape when both shape and hue could be used to correctly categorize stimuli. We suggest that both the positive and negative effects of words have developmental origins in the history of word usage while learning categories. [corrected]
