Опубликована Сен. 18, 2014

The influence of expectation on inattentional blindness (IB) was investigated using a lexical-based IB task. In two experiments, 235 participants performed word compilations from briefly presented letters and combinations of letters with an unexpected syllable appearing in one of the trials. In Experiment 1, we varied the frequency and grammatical form ofthe presented words, evaluating the role of “general” and “contextual” expectations. The results showed the effect of frequency but not of the grammatical form of the words. Experiment 2 controlled for the role of the state of completion of the word compilation in generating “contextual” expectations. We varied two …

A great amount of evidence has now been accumulated indicating that many aspects of cognition, including language are closely interconnected with or “grounded” in the sensory-motor modalities. In this respect, an interesting line of research that has not yet been studied in great detail is whether activation of the sensory-motor brain areas can be found when figurative language is processed. Two experiments were conducted to address the following questions: firstly, can evidence of effector-specific motor activation be found in the processing of idioms; secondly, how would such activation unfold in time? We hypothesized that highly imageable idioms are more strongly …

Theories of Implicit Learning: Contradictory Approaches to the Same Phenomenon or Consistent Descriptions of Different Types of Learning?

Ivan Ivanchei

Опубликована Янв. 1, 2014

Almost 50 years ago, Reber described implicit learning as the unintentional and unconscious processing of regularities in the environment. Since then, psychologists have actively investigated this phenomenon. However, there is currently no unambiguous description of the mechanisms of implicit learning. Moreover, the descriptions of implicit learning properties vary depending on the approach to the phenomenon. The main theoretical accounts developed in the last decades are presented in this work. Four types of theories are identified, which differ in how they answer two main questions: 1) How explicit is the knowledge acquired during implicit learning?; and 2) How automatically is it …

The influences of intentionality and effectiveness of adults’ behavior on infants’ imitation of object-related actions

In the second year of life, infants are actively interested in objects used by adults, despite the number of experienced difficulties in achieving their goals while handling these objects. What causes the child attempt to handle an object for a designated purpose while watching the adult? One of the evident explanations concerns the effectiveness of the adults behavior and the child’s desire to achieve the same result. However, multiple studies have shown that a child is guided not exclusively by the hoped-for result, but also by the adults intention. In our study, we verified the reason guiding a child’s choice …

This paper describes the possible methodological techniques of evaluation of the problem solving process as the main task by a secondary probe task. We propose a method of estimation of the microdynamics of thought processes via changes in the dynamics of working memory load in problem solving by a probe monitor. The results of assessment of the dynamics of working memory load in insight and algorithmized problem solving via a two-alternative choice task are shown. There are significant differences between the dynamics of working memory load in insight and algorithmized problem solving in the last stages, which confirm the hypothesis …

Analysis of factors affecting codon usage bias in human papillomavirus

Indices of codon usage pattern of human papillomavirus (HPV) were analyzed to understand the key determinants of synonymous codon usage in the HPV genome. The complete sequences of 39 HPV genomes were downloaded from the website of the National Center for Biotechnology Information. The relative synonymous codon usage values, effective number of codons, GC content, percentage of GCs at the third position of synonymous codons (GC3s), codon adaptation index, hydrophobicity, aromaticity of conceptually translated gene products were calculated using the Codon W 1.4.2 program. HPV preferentially used codons ending with A/U. By comparing relative synonymous codon usage of the HPV …

Evaluating the computing efficiencies (specificity and sensitivity) of graphics processing unit (GPU)-accelerated DNA sequence alignment tools against central processing unit (CPU) alignment tool

Bioinformatics is an emerging field, where information technology usage can significantly accelerate life science research. It is a relatively new field and the scope of exploring new tools and techniques seems immense. One major field where bioinformatics plays important role is next generation sequence analysis (NGS), in which an unknown genome is shuttered into pieces and tried to align it to a reference known genome to decipher its functions using sequence comparison. The first well known application of this technology is the human genome project which took nearly 10 years to finish. With advancements in central processing units (CPUs), the …

The Two Eyes of the Blind Mind: Object vs. Spatial Aphantasia?

Individual variability in imagery experiences has long attracted the interest of philosophers, educators, and psychologists. Since Aristotle’s time, it was assumed that imagery is a universal ability, so everyone possesses it. Galton first measured the vividness of subjective imagery experiences, and discovered that some individuals reported zero imagination. Recent research has coined the term “aphantasia” — an inability to form mental imagery, or having a “blind mind’s eye” (Zeman, Dewar, & Della Sala, 2015). We argue that there maybe more than one type of aphantasia. Substantial behavioral and neuropsychological evidence has demonstrated a distinction between visual-object imagery (mental visualization of …

This study was conducted to assess provider perceptions regarding value of tablet-based patient-reported outcome (PRO) assessments in routine care. Patients self-administered a brief PRO assessment of several clinical domains on-site prior to HIV clinic visits. Providers were given succinct summary results. 1:1 interviews were conducted with providers regarding PROs utility and their integration into care, and coded interview transcripts into thematic areas. Providers described how PROs helped prioritize topics for discussion during the visit, and facilitated their identification and ability to address sensitive issues, particularly depression/suicidality, sexual behavior, and intimate partner violence. PROs further facilitated comprehensive identification of other issues …

Adaptation or Assimilation? Sequential Effects in the Perception of Dynamic and Static Facial Expressions of Emotion

Olga A. Korolkova

Опубликована Июнь 24, 2018

In emotional facial expressions, sequential effects can result in perceptual changes of a briefly presented test expression due to a preceding prolonged exposure to an adaptor expression. Most studies have shown contrastive (adaptation) aftereffects using static adaptors: a test is perceived as less similar to the adaptor. However, the existence and sign of sequential effects caused by dynamic information in the adaptors are controversial. In a behavioral experiment we tested the influence of realistic (recorded from an actors face) and artificial (linearly morphed) dynamic transitions between happy and disgusted facial expressions, and of static images of these expressions at their …
