Prior's puzzle generalized

Prior's puzzle is standardly taken to be the puzzle of why, given the assumption that that-clauses denote propositions, substitution of $⌜$the proposition that $P$$⌝$ for $⌜$that $P$$⌝$ within the complements of many propositional attitude verbs is invalid. I show that Prior's puzzle is much more general than is ordinarily supposed. There are two variants on the substitutional form of the puzzle—a quantificational variant and a pronominal variant—and all three forms of the puzzle arise in a wide range of verbal complements, rather than merely in the complements of propositional attitude verbs. The generalized puzzle shows that a range of proposed solutions to the original puzzle fail, or are radically incomplete, and also reveals the connections between Prior's puzzle and debates over the nature of semantic types and higher-order quantification. I go on to develop a novel, higher-order solution to the generalized form of the puzzle, and I argue that this higher-approach is superior to its first-order alternatives.     

Insufficient Effort Responding as a Potential Confound between Survey Measures and Objective Tests

Following research that demonstrates insufficient effort responding (IER) may confound survey measures and inflate observed correlations (Huang, Liu, & Bowling, 2015c), a question emerges as to whether and when IER can act as a confound between objective tests and surveys. Using data (N?=?243) originally designed to examine training and transfer, study 1 demonstrates that (a) IER is negatively related to performance on tests, and (b) IER’s influence on surveys depends on the sample means of these measures. As a result, IER could inflate a test’s association with other tests and surveys. Study 2 investigates the impact of two parameters—within-person consistency of IER and percentage of IER cases in the sample—by randomly replacing bootstrapped attentive responses (10,000 bootstrapped samples of 200 cases identified from study 1). When predicting the confounding effects of IER, within-person consistency has positive linear and quadratic effects, percentage of IER cases has a positive linear effect, and consistency and percentage have a positive interactive effect. Research and practical implications for the design and evaluation of surveys and tests are discussed.

     

Effect of cognitive bias modification-memory on depressive symptoms and autobiographical memory bias: two independent studies in high-ruminating and dysphoric samples

Memory bias is a risk factor for depression. In two independent studies, the efficacy of one CBM-Memory session on negative memory bias and depressive symptoms was tested in vulnerable samples. We compared positive to neutral (control) CBM-Memory trainings in highly-ruminating individuals (N?=?101) and individuals with elevated depressive symptoms (N?=?100). In both studies, participants studied positive, neutral, and negative Swahili words paired with their translations. In five study–test blocks, they were then prompted to retrieve either only the positive or neutral translations. Immediately following the training and one week later, we tested cued recall of all translations and autobiographical memory bias; and also measured mood, depressive symptoms, and rumination. Retrieval practice resulted in training-congruent recall both immediately after and one week after the training. Overall, there was no differential decrease in symptoms or difference in autobiographical memory bias between the training conditions. In the dysphoric but not in the high-ruminating sample, the positive training resulted in positive autobiographical bias only in dysphoric individuals with positive pre-existing bias.

We conclude that one session of positive retrieval-based CBM-Memory may not be enough to yield symptom change and affect autobiographical memory bias in vulnerable individuals.
