Semantic Similarity of Alternatives Fostered by Conversational Negation

Conversational negation often behaves differently from negation as a logical operator: when rejecting a state of affairs, it does not present all members of the complement set as equally plausible alternatives, but it rather suggests some of them as more plausible than others (e.g., “This is not a dog, it is a wolf/*screwdriver”). Entities that are semantically similar to a negated entity tend to be judged as better alternatives (Kruszewski et al., 2016). In fact, Kruszewski et al. (2016) show that the cosine similarity scores between the distributional semantics representations of a negated noun and its potential alternatives are highly correlated with the negated noun-alternatives human plausibility ratings. In a series of cloze tasks, we show that negation likewise restricts the production of plausible alternatives to similar entities. Furthermore, completions to negative sentences appear to be even more restricted than completions to an affirmative conjunctive context, hinting at a peculiarity of negation.     

Motivational–cognitive profiles of learners: Cluster movement

The present study was designed to identify the motivational–cognitive profiles of students in Singapore secondary schools using cluster movement. Five distinct motivated strategies for learning (MSL) profiles based on a sample of 304 students were revealed: those with low levels of motivational beliefs and cognition but high anxiety (Poor MSL); high motivational beliefs and cognition but low anxiety (Good MSL); moderate high motivational beliefs, cognition and anxiety (Average MSL); high motivational beliefs, cognition and anxiety (High MSL); and low motivational beliefs, cognition and anxiety (Low MSL). Findings of this study also showed cluster movement across two time points, revealing the shifts in cluster membership in terms of motivational–cognitive profiles over time. Students in Good MSL demonstrated the most adaptive learning profile and achieved the highest grades than other clusters. Our findings contributed to practical underpinnings of educational research as well as provided meaningful insights to both researchers and practitioners.     

Moderating effects of appreciation on relationships between illegitimate tasks and intrinsic motivation: a two-wave shortitudinal study

ABSTRACT

This study investigated possible reciprocal relationships between illegitimate tasks and intrinsic motivation and whether appreciation moderated these relationships. Based on a two-wave panel study across one week and a sample of 366 nurses, we examined whether appreciation buffered effects of illegitimate tasks on reduced intrinsic motivation; or enhanced reversed effects of intrinsic motivation on decreased perceived illegitimate tasks. Additionally, we differentiated whether illegitimate tasks and appreciation were elicited by supervisors, colleagues, or patients. Latent structural equation analyses primarily revealed effects for unnecessary than for unreasonable tasks. Such tasks were predominantly the consequence rather than the cause of intrinsic motivation, and intrinsic motivation increased perceived illegitimate tasks under conditions of low appreciation. Regarding the different sources, most effects were present for illegitimate tasks ascribed by supervisors and for appreciation conveyed by patients. It follows that the perception of illegitimate tasks seems to be a matter of motivation; that the sources of illegitimate tasks and appreciation matter; and that appreciation as a low-budget, but highly powerful practice, is able to facilitate a positive environment where work tasks are less likely to be perceived as illegitimate.     

Conflict tasks and the diffusion framework: Insight in model constraints based on psychological laws

Formal models of decision-making have traditionally focused on simple, two-choice perceptual decisions. To date, one of the most influential account of this process is Ratcliff’s drift diffusion model (DDM). However, the extension of the model to more complex decisions is not straightforward. In particular, conflicting situations, such as the Eriksen, Stroop, or Simon tasks, require control mechanisms that shield the cognitive system against distracting information. We adopted a novel strategy to constrain response time (RT) models by concurrently investigating two well-known empirical laws in conflict tasks, both at experimental and modeling levels. The two laws, predicted by the DDM, describe the relationship between mean RT and (i) target intensity (Piéron’s law), (ii) standard deviation of RT (Wagenmakers–Brown’s law). Pioneering work has shown that Piéron’s law holds in the Stroop task, and has highlighted an additive relationship between target intensity and compatibility. We found similar results in both Eriksen and Simon tasks. Compatibility also violated Wagenmakers–Brown’s law in a very similar and particular fashion in the two tasks, suggesting a common model framework. To investigate the nature of this commonality, predictions of two recent extensions of the DDM that incorporate selective attention mechanisms were simulated and compared to the experimental results. Both models predict Piéron’s law and the violation of Wagenmakers–Brown’s law by compatibility. Fits of the models to the RT distributions and accuracy data allowed us to further reveal their relative strengths and deficiencies. Combining experimental and computational results, this study sets the groundwork for a unified model of decision-making in conflicting environments.     

Children’s attributions of beliefs to humans and God: cross-cultural evidence

The capacity to attribute beliefs to others in order to understand action is one of the mainstays of human cognition. Yet it is debatable whether children attribute beliefs in the same way to all agents. In this paper, we present the results of a false-belief task concerning humans and God run with a sample of Maya children aged 4-7, and place them in the context of several psychological theories of cognitive development. Children were found to attribute beliefs in different ways to humans and God. The evidence also speaks to the debate concerning the universality and uniformity of the development of folk-psychological reasoning.
