Constructional associations trump lexical associations in processing valency coercion

The paper investigates the interaction of lexical and constructional meaning in valency coercion processing, and the effect of (in)compatibility between verb and construction for its successful resolution (Perek, Florent & Martin Hilpert. 2014. Constructional tolerance: Cross-linguistic differences in the acceptability of non-conventional uses of constructions. Constructions and Frames 6(2). 266–304; Yoon, Soyeon. 2019. Coercion and language change: A usage-based approach. Linguistic Research 36(1). 111–139). We present an online experiment on valency coercion (the first one on Italian), by means of a semantic priming protocol inspired by Johnson, Matt A. & Adele E. Goldberg. 2013. Evidence for automatic accessing of constructional meaning: Jabberwocky sentences prime associated verbs. Language & Cognitive Processes 28(10). 1439–1452. We test priming effects with a lexical decision task which presents different target verbs preceded by coercion instances of four Italian argument structure constructions, which serve as primes. Three types of verbs serve as target: lexical associate (LA), construction associate (CA), and unrelated (U) verbs. LAs are semantically similar to the main verb of the prime sentence, whereas CAs are prototypical verbs associated to the prime construction. U verbs serve as a mean of comparison for the two categories of interest. Results confirm that processing of valency coercion requires an integration of both lexical and constructional semantics. Moreover, compatibility is also found to influence coercion resolution. Specifically, constructional priming is primary and independent from compatibility. A secondary priming effect for LA verbs is also found, which suggests a contribution of lexical semantics in coercion resolution – especially for low-compatibility coercion coinages.

Developing and Understanding Olfactory Evaluation of Boar Taint

Trained expert panels are used routinely in boar taint research, with varying protocols for training of panelists and scoring methods. We describe a standardized process for training and scoring, to contribute to standardize the olfactory detection of boar taint. Three experiments are described in which we (1) evaluate the importance of training and the effect of the previous sample, (2) determine detection thresholds on strips and in fat for our panel, and (3) test priming panelists before boar taint evaluation. For the final evaluation of boar taint, we propose a consistent three-person evaluation scoring on a 0–4 scale using a final mean score of 0.5 as the cut-off for boar taint. This gave an optimal sensitivity of 0.81 and a specificity of 0.56 compared to chemical cut-offs. Even limited training proved useful, but priming assessors with strips did not improve the evaluation of fat samples. Detection thresholds were higher in fat compared to strips, except for indole. We recommend panelists to always smell a non-tainted control sample after a tainted one as a ‘reset’ mechanism, before continuing. For longitudinal studies, we additionally advise to set up an expert panel with a fixed number of assessors performing each evaluation in duplicate.

Memory, Amnesia, and Dissociative Identity Disorder

Virtually all patients with dissociative identity (or multiple personality) disorder manifest interpersonality amnesia, whereby events experienced by a particular personality state or identity are retrievable by that same identity but not by a different one Though considered a hallmark of dissociative identity disorder (DID), interpersonality amnesia has to date attracted little empirical attention. Further, the few studies on the topic typically include just 1 DID patient and a single index of retention In contrast the current experiment involved 9 DID patients and several measures of either explicit or implicit memory Replicating and extending the single-case study of Nissen, Ross, Willingham, MacKenzie, and Schacter (1988), the present results revealed that implicit testing is a necessary but not a sufficient condition for demonstrating transfer of information from one identity to another Specifically, whereas priming in word-stem completion occurred only if the same personality state performed at both study and at test, priming in picture-fragment completion was as robust between different identities as it was within the same identity Discussion focuses on prospects for future research aimed at understanding the nature and scope of interpersonality amnesia

Priming Improves Germination and Emergence of Combine-harvested Amaranths cruentus L. Seeds

Hand-harvested and threshed grain amaranth seeds stored for 6.5 years and combine-harvested and threshed seeds (cylinder speed 26.4 m·s-1) stored for 9.5 years were subjected to several osmotic priming treatment. The selected priming treatment (–1.25 MPa polyethylene glycol at 15C for 10 days) increased percent radicle emergence of hand-harvested seeds and mechanically damaged, combine-harvested seeds and resulted in germination rates that were at least as high as those achieved with other priming treatments. In an incubator test, priming increased percent radicle emergence of hand-harvested seeds only at 15C; however, it increased percent radicle emergence of combine-harvested seeds at 15 and 35C. Priming also increased radicle emergence rate, but this response was more pronounced and exerted over a wider temperature range for the older, lower-vigor, combine-harvested seeds than for the younger, higher-vigor, hand-harvested seeds. In a greenhouse test, hand-harvested seeds had a higher percentage of normal seedlings and a lower percentage of abnormal seedlings than combine-harvested seeds. Priming had no effect on these variables. As a result of priming, normal seedling emergence rate and shoot fresh weight were higher from combine-harvested seeds than from hand-harvested seeds, such that values of these variables for primed, combine-harvested seeds were at least equal to those for nonprimed, hand-harvested seeds. Thus, the invigorating effect of priming was more pronounced for the lower-vigor, mechanically damaged, combine-harvested seeds than for the higher-vigor, hand-harvested seeds.

Priming Compared to Recall: Following Multiple Exposures and Delay

The activation of words can be measured directly, by recall, or indirectly, by noting their occurrence as associates on a subsequent association test (priming). 12 groups of Ss had 0, 1, 2, or 4 exposures to 14 words, using one intentional and two incidental learning tasks. 6 additional groups, after 1, 2, or 4 presentations of the words for intentional learning, had a 6- or 12-min. delay before taking the association test. All 15 experimental groups had significantly better recall after more exposures and less delay. The priming effects, however, were affected neither by repeated exposure nor by delay. More primed associates were elicited on the association test after one exposure than after two. Priming and recall, thus, seem to measure two distinct processes.
