Soames’s new conception of propositions

In this paper, I argue that, when it comes to explaining what can be described as “representational” properties of propositions, Soames’s new conception of propositions—on which the proposition that Seattle is sunny is the act of predicating the property being sunny of Seattle and to entertain that proposition is to perform that act—does not have an advantage over traditional ones.     

Description of an Intensive Dialectical Behavior Therapy Program for Multidiagnostic Clients With Eating Disorders

The authors describe an intensive outpatient dialectical behavior therapy (DBT) program for multidiagnostic clients with eating disorders who had not responded adequately to standard, empirically supported treatments for eating disorders. The program integrates DBT with empirically supported cognitive behavior therapy approaches that are well established for the treatment of eating disorders. Attention is given to inclusion and exclusion criteria, how the program differs from standard treatments for eating disorders, and the application of specific DBT treatment components for multidiagnostic clients with eating disorders.     

Speeded induction under uncertainty: The influence of multiple categories and feature conjunctions

When people are uncertain about the category membership of an item (e.g., Is it a dog or a dingo?), research shows that they tend to rely only on the dominant or most likely category when making inductions (e.g., How likely is it to befriend me?). An exception has been reported using speeded induction judgments where participants appeared to use information from multiple categories to make inductions (Verde, Murphy, &; Ross, 2005). In two speeded induction studies, we found that participants tended to rely on the frequency with which features co-occurred when making feature predictions, independently of category membership. This pattern held whether categories were considered implicitly (Experiment 1) or explicitly (Experiment 2) prior to feature induction. The results converge with other recent work suggesting that people often rely on feature conjunction information, rather than category boundaries, when making inductions under uncertainty.     

Giving cognition a helping hand: The effect of congruent gestures on object name retrieval

The gestures that accompany speech are more than just arbitrary hand movements or communicative devices. They are simulated actions that can both prime and facilitate speech and cognition. This study measured participants’ reaction times for naming degraded images of objects when simultaneously adopting a gesture that was either congruent with the target object, incongruent with it, and when not making any hand gesture. A within‐subjects design was used, with participants (N= 122) naming 10 objects under each condition. Participants named the objects significantly faster when adopting a congruent gesture than when not gesturing at all. Adopting an incongruent gesture resulted in significantly slower naming times. The findings are discussed in the context of the intrapersonal cognitive and facilitatory effects of gestures and underline the relatedness between language, action, and cognition.     

Detection of increments in noise intensity by monkeys

Monkeys were trained to detect 100-msec increments in the intensity of continuous white noise. A response on one of two bars was reinforced with some probability if it conformed to the presence or absence of the increment on that trial. Stimulus parameters of background intensity, increment size, and probability of increment presentation were varied, and response probabilities and latencies were recorded. The task was analogous to the "yes-no" task used in human psychophysics. Data analysis within the context of signal-detection theory revealed response biasing toward one bar or the other to be related to the probability of increment presentation, whereas sensitivity depended on the combination of increment size and background noise intensity. Weber's law was found to hold for a large range of background intensities in that the sensitivity to relative intensity increments varied little. Performance was compared to that of an ideal observer that uses samples of the envelope of the noise waveform on which to base its responses.     

Environmental Attention,Affect, and Altruism1

Three experiments were conducted concerning the effect of attention to positive or negative images of the physical environment on altruistic behavior: I. Some subjects listed and described aspects of their residential environments that were particularly pleasant while others described particularly unpleasant aspects. II. Subjects were exposed to slides of either attractive or unattractive outdoor environments. III. Subjects viewed slides of either attractive or unattractive environments while adopting an attentional set that focused only on positive or negative aspects of the slides. After these manipulations, subjects in each experiment encountered an ostensibly unrelated confederate who sought their assistance as a favor. Experiment I subjects who had thought about pleasant environments spent significantly more time helping than those who thought about unpleasant enviornments. Experiment II subjects who saw slides of attractive environments offered significantly more aid for a longer time period than subjects who saw slides of unattractive environments. Experiment III subjects who focused on positive aspects of attractive enviornments gave more help than subjects who focused on negative aspects of attractive environments, though overall differences were not significant. Attentional set produced no differential helping effects in subjects who had viewed unattractive environments. In all three experiments mood or affect was discussed as mediating the impact of environments on behavior.

Attentional functions of cortical cholinergic inputs: what does it mean for learning and memory?

The hypothesis that cortical cholinergic inputs mediate attentional functions and capacities has been extensively substantiated by experiments assessing the attentional effects of specific cholinotoxic lesions of cortical cholinergic inputs, attentional performance-associated cortical acetylcholine release, and the effects of pharmacological manipulations of the excitability of basal forebrain corticopetal cholinergic projections on attentional performance. At the same time, numerous animal experiments have suggested that the integrity of cortical cholinergic inputs is not necessary for learning and memory, and a dissociation between the role of the cortical cholinergic input system in attentional functions and in learning and memory has been proposed. We speculate that this dissociation is due, at least in part, to the use of standard animal behavioral tests for the assessment of learning and memory which do not sufficiently tax defined attentional functions. Attentional processes and the allocation of attentional capacities would be expected to influence the efficacy of the acquisition and recall of declarative information and therefore, persistent abnormalities in the regulation of the cortical cholinergic input system may yield escalating impairments in learning and memory. Furthermore, the cognitive effects of loss of cortical cholinergic inputs are augmented by the disruption of the top-down regulation of attentional functions that normally acts to optimize information processing in posterior cortical areas. Because cortical cholinergic inputs play an integral role in the mediation of attentional processing, the activity of cortical cholinergic inputs is hypothesized to also determine the efficacy of learning and memory.
