On a fallacy attributed to tarski

The purpose of this paper is to examine some passages of Tarski‘s paper ’On the concept of logical consequence’ and to show that some recent readings of those passages are wrong. John Etchemendy has claimed that in those passages Tarski gave an argument purporting to show that the notion of logical consequence defined by him (as opposed to some pretheoretic notion of logical consequence) possesses certain modal properties. Etchemendy further claims that the argument he attributes to Tarski is fallacious. Some of Etchemendy’s critics have granted him that Tarski did give an argument purporting to show that the defined notion possesses certain modal properties ; but they have claimed that Tarski’s argument was not a fallacious one. I will show that both Etchemendy and his critics are wrong; in the relevant passages, Tarski did not offer (nor did he intend to offer) an argument that the defined notion of logical consequence possesses any modal properties     

Dispositional Attachment Orientations,Contextual Variations in Attachment Security,and Compassion Fatigue Among Volunteers Working With Traumatized Individuals

In the present article, we report a series of studies examining the links between attachment orientations and compassion fatigue among volunteers working with traumatized individuals. Participants were volunteers in several trauma‐related organizations, ranging in age from 18 to 69 years. In Study 1 (N = 148), we examined associations between self‐reports of attachment insecurities and compassion fatigue. In Study 2 (N = 54), we used a diary design to assess attachment‐related differences in emotional reactions to actual helping encounters over a 2‐month period. In Study 3 (N = 108), we examined the effects of the experimental enhancement of attachment security (security priming) on reactions to a hypothetical helping encounter. As expected, attachment insecurities, either anxiety or avoidance, were associated with heightened compassion fatigue. Moreover, security priming reduced compassion fatigue in response to a hypothetical helping encounter. These findings underscore the relevance of attachment theory for understanding and preventing compassion fatigue.     

Individual differences make a difference: On the use and the psychometric properties of difference scores in social psychology

Much social psychological research is concerned with the question whether and how behavior changes because of a “treatment” (e.g., a situation that triggers a psychological reaction). One easy way to investigate such changes would be to analyze intraindividual differences before (Time 1) and after the treatment (Time 2). Interestingly, many scholars refrain from using difference scores because they think they are inherently unreliable. However, the bad reputation of difference scores is, in many cases, unwarranted: difference scores can be sufficiently reliable when standard deviations differ between measurement occasions, and standard deviations are likely to differ between measurement occasions because of differential treatment effects (i.e., interindividual differences in responsiveness to a treatment) and/or “strong situation” treatments. In the present article, we will (1) summarize classic and current arguments regarding the reliability of difference scores, (2) discuss the use of residual change scores as an alternative to difference scores, and (3) argue that latent difference score models are a particularly useful tool that social psychologists should consider using more frequently.

Classical conditioning and pain: Conditioned analgesia and hyperalgesia

This article reviews situations in which stimuli produce an increase or a decrease in nociceptive responses through basic associative processes and provides an associative account of such changes. Specifically, the literature suggests that cues associated with stress can produce conditioned analgesia or conditioned hyperalgesia, depending on the properties of the conditioned stimulus (e.g., contextual cues and audiovisual cues vs. gustatory and olfactory cues, respectively) and the proprieties of the unconditioned stimulus (e.g., appetitive, aversive, or analgesic, respectively). When such cues are associated with reducers of exogenous pain (e.g., opiates), they typically increase sensitivity to pain. Overall, the evidence concerning conditioned stress-induced analgesia, conditioned hyperalagesia, conditioned tolerance to morphine, and conditioned reduction of morphine analgesia suggests that selective associations between stimuli underlie changes in pain sensitivity.
