Breaking Surface Feature Continuity of Previewed Mask Reinstates Object Substitution Masking12

Perception of a briefly presented target is impaired when a sparse surrounding mask (e.g., four-dot) persists after target offset compared to when the target and mask offset together (i.e., object substitution masking [OSM]). Previous studies have reported a mask preview effect in which OSM is largely attenuated by prior presentation of the mask. Here, we investigated how breaking object continuity of the previewed mask affects the mask preview effect. Introducing an abrupt surface color change of the previewed mask at target onset disrupted the beneficial effect of mask preview, that is, OSM was reinstated (Experiment 1). The masking induced by mask color change exhibited the same two characteristics as conventional OSM: target location specificity and non-necessity of voluntary attention to the mask (Experiment 2). These results suggest that a sudden change in surface color breaks object continuity of the previewed mask and causes the mask to be represented as a new one, which triggers OSM anew.     

Boo! The consciousness problem in emotion

ABSTRACT

This paper will examine the conscious aspects of emotion (i.e. emotional experience), arguably the defining features of emotion. I will argue that emotion IS emotional experience and, consequently, that emotion researchers rarely study emotion itself. I will suggest a research agenda for examining the conscious aspects of emotion and end with a consideration of appraisal theory and how it can be made more relevant to the study of emotion by treating appraisals as components of a pre-reflective perceptual process rather than as causal antecedents of a cognitive process that can be self-reported on.     

Predicting Reading Comprehension in Arabic-Speaking Middle Schoolers Using Linguistic Measures

Abstract

This study aimed at examining the contribution of various linguistic components to reading comprehension (RC) in the seventh and ninth grades and to compare this contribution between two groups: children with typical development and those with reading disorders (RD). This was done by testing the relative contribution of phonological awareness, morphological knowledge, vocabulary, and syntactic knowledge to RC in both groups. The regression analysis indicated that the linguistic components explain between 60 and 56% of the variance in RC in the seventh and ninth grades among the typical group and between 74 and 79% in the same grades among those with RD. While phonological awareness and morphological knowledge contribute to RC only among the RD group, the contributions of vocabulary and syntactic knowledge were found to be significant in both groups. The results are discussed in light of previous findings in the literature with theoretical and pedagogical implications.     

A Note on the Conversion of Item Parameters Standard Errors

The relations among alternative parameterizations of the binary factor analysis (FA) model and two-parameter logistic (2PL) item response theory (IRT) model have been thoroughly discussed in literature. However, the conversion formulas widely available are mainly for transforming parameter estimates from one parameterization to another. There is a lack of discussion about the standard error (SE) conversion among different parameterizations, when SEs of IRT model parameters are often of immediate interest to practitioners. This article provides general formulas for computing the SEs of transformed parameter values, when these parameters are transformed from FA to IRT models. These formulas are suitable for unidimensional 2PL, multidimensional 2PL, and bi-factor 2PL models. A simulation study is conducted to verify the formula by providing empirical evidence. A real data example is given in the end for an illustration.     

Testing attitudes,social desirability and behavioral regulations as moderators of implicit-explicit exercise discrepancies: A replication study in Iranian students

IntroductionThere is mixed evidence regarding moderators of the relationship between implicitly and explicitly measured constructs. This study examined this issue with evaluations of exercise relative to health or appearance in a sample of Iranian adolescents. Investigaing automatic associations and reflective constructs might provide important implications for developing interventions targeting exercise behavior in a population with different cultural, social, and economic barriers to exercise than European or North American adolescents.MethodsParticipants were 471 students enrolled in grades 9 to 12, of whom 269 (54.9%) were female. Behavioral regulations, explicit attitudes, and social desirability were investigated as possible moderators. All students completed questionnaire measures of physical activity behavior, attitudes, social desieality and behavioral regulation. They also completed two Go/No Go Association tasks to measure automatic associations of exercise with health and apperarance.ResultsAttitude was a significant moderator of discrepancies between automatic associations of exercise with health and health motives. Interjected regulation moderated implicit-explicit appearance discrepancies. Participants with low social desirability and negative automatic appearance associations had the highest appearance motivation.ConclusionsParticipants focused on the potential of achieving positive health outcomes of exercise rather than physical appearance outcomes, which differs from research from other countries. It is possible that, health was strongly linked with exercise by the pervasive societal pressures in Iran to have a healthy body.     

Unconscious integration: Current evidence for integrative processing under subliminal conditions

Integrative processing is traditionally believed to be dependent on consciousness. While earlier studies within the last decade reported many types of integration under subliminal conditions (i.e. without perceptual awareness), these findings are widely challenged recently. This review evaluates the current evidence for 10 types of subliminal integration that are widely studied: arithmetic processing, object-context integration, multi-word processing, same-different processing, multisensory integration and 5 different types of associative learning. Potential methodological issues concerning awareness measures are also taken into account. It is concluded that while there is currently no reliable evidence for subliminal integration, this does not necessarily refute ‘unconscious’ integration defined through non-subliminal (e.g. implicit) approaches.     

The role of executive function in reading comprehension among beginning readers

Empirical evidence supports the importance of executive function (EF) in reading, but the underlying mechanism through which EF contributes to the reading process is unclear. The present study examined the direct and indirect effects of EF on reading comprehension through the indirect pathway of language and cognitive skills (i.e., syntactic awareness and text-connecting inferencing) among the beginning readers. The sample included one hundred and sixty-five 2^nd and 3^rd grade students. The participants were tested on working memory (visuospatial working memory and verbal working memory) and inhibition (prepotent response inhibition and cognitive inhibition), and their syntactic awareness, inference-making, and reading comprehension. The unitary EF construct was obtained by means of confirmatory factor analysis based on the structure of EF in middle childhood suggested in developmental studies. Structural equation modelling was used to examine the direct and indirect effects of EF on the reading outcome. The findings indicated that EF has a direct effect on reading comprehension among the beginning readers. The indirect pathway showed that EF supports the ability to evaluate on grammatical structure of sentences (i.e., syntactic awareness) during reading. However, the indirect effect of EF on reading via inference-making ability is insignificant. The findings highlight the contributions of EF to reading and provide empirical evidence to the hypothetical relation between EF and language skills suggested in DIER (Kim, 2020, Resarch Quarterly, 50, 459). It further extends our knowledge on the roles of EF in the reading process among the beginning readers. Future research directions are implicated as well.     

Weighing the evidence for a dorsal processing bias under continuous flash suppression

With the introduction of continuous flash suppression (CFS) as a method to render stimuli invisible and study unconscious visual processing, a novel hypothesis has gained popularity. It states that processes typically ascribed to the dorsal visual stream can escape CFS and remain functional, while ventral stream processes are suppressed when stimuli are invisible under CFS. This notion of a CFS-specific “dorsal processing bias” has been argued to be in line with core characteristics of the influential dual-stream hypothesis of visual processing which proposes a dissociation between dorsally mediated vision-for-action and ventrally mediated vision-for-perception. Here, we provide an overview of neuroimaging and behavioral studies that either examine this dorsal processing bias or base their conclusions on it. We show that both evidence for preserved ventral processing as well as lack of dorsal processing can be found in studies using CFS. To reconcile the diverging results, differences in the paradigms and their effects are worthy of future research. We conclude that given the current level of information a dorsal processing bias under CFS cannot be universally assumed.     

Discounting mechanism underlies extinction illusion

Humans can perceive a coherent visual scene despite a low spatial resolution in peripheral vision. How does the visual system determine whether an object exists in the periphery? We addressed this question by focusing on the extinction illusion in which a disk becomes subjectively invisible when presented at the intersection of grids. We hypothesized that the disk would go unnoticed when the stimuli with and without the disk produced the same strength of visual signals. The visual system would miss the disk by confounding the target signals with the intersection signals that should be discounted. Computational analysis revealed that the energy ratio between the stimuli with and without the disk decreased with stimulus eccentricity and such energy ratio could successfully explain the observer’s d’ to detect the disk. These results indicate that the discounting mechanism relying on stimulus energy determines the awareness toward a peripheral object.
