On adaptation, maximization, and reinforcement learning among cognitive strategies

Analysis of binary choice behavior in iterated tasks with immediate feedback reveals robust deviations from maximization that can be described as indications of 3 effects: (a) a payoff variability effect, in which high payoff variability seems to move choice behavior toward random choice; (b) underweighting of rare events, in which alternatives that yield the best payoffs most of the time are attractive even when they are associated with a lower expected return; and (c) loss aversion, in which alternatives that minimize the probability of losses can be more attractive than those that maximize expected payoffs. The results are closer to probability matching than to maximization. Best approximation is provided with a model of reinforcement learning among cognitive strategies (RELACS). This model captures the 3 deviations, the learning curves, and the effect of information on uncertainty avoidance. It outperforms other models in fitting the data and in predicting behavior in other experiments.     

Using talking computers to remediate reading and spelling disabilities: The critical role of the print-to-sound unit

Talking computers employing computer-generated speech feedback have been used to remediate the literacy skills of dyslexic readers. A computer program is described that employs DECtalk, a highlevel speech synthesizer, to narrate instruction involving intensive training in identifying whole words or in identifying and blending word segments corresponding to onsets, rimes, and phonemes. Procedures for developing individualized instruction are described as well as for constructing and editing the speech and graphics features of the program. Neurologically impaired dyslexic children trained with this program achieved greater acquisition and transfer of word recognition skill when their training involved segmented rather than whole word feedback.     

SMARTS and SMARTER: Improved Simple Methods for Multiattribute Utility Measurement

This paper presents two approximate methods for multiattribute utility measurement, SMARTS and SMARTER, each based on an elicitation procedure for weights. Both correct an error in SMART, originally proposed by Edwards in 1977, and in addition SMARTER is simpler to use. SMARTS uses linear approximations to single-dimension utility functions, an additive aggregation model, and swing weights. The paper proposes tests for the usability of these approximations. SMARTER, based on a formally justifiable weighting procedure developed by Barron and Barrett, uses the same procedures as SMARTS except that it omits the second of two elicitation steps in swing weights, substituting calculations based on ranks. It can be shown to perform about 98% as well as SMARTS does, without requiring any difficult judgments from elicitees.     

What's in a name: what analyst and patient call each other

Awkward moments often arise between patient and analyst involving the question, "What do we call each other?" The manner in which the dyad address each other contains material central to the patient's inner life. Names, like dreams, deserve a privileged status as providing a royal road into the paradoxical analytic relationship and the unconscious conflicts that feed it. Whether an analyst addresses the patient formally, informally, or not at all, awareness of the issues surrounding names is important.

Randomized Control Trial of Teaching Recovery Techniques in Rural Occupied Palestine: Effect on Adolescent Dissociation

This study assessed the effect of a cognitive behavioral group intervention, Teaching Recovery Techniques (TRT), for adolescents with high levels of posttraumatic stress (n = 154), from villages in occupied Palestine. A randomized control trial involved standardized measures to assess war stressors, posttraumatic stress, depression, and dissociation. Program fidelity was measured by presenter and observer ratings and program delivery cost was calculated per adolescent. High levels of traumatic exposure, dissociation, and posttraumatic stress were found. In comparison to a wait list group (n = 75), TRT adolescents reported significantly fewer posttraumatic stress symptoms postintervention. Depression and dissociation remained stable for TRT adolescents, but worsened for those on the wait list. Given the high returns and low costs, this cost–benefit analysis makes a clear case for TRT to be delivered throughout the West Bank. Longitudinal evaluation is needed to assess adolescent traumatization and the impact of TRT within a context of ongoing violence.
