Results from the development of a novel sensory and perceptual test to assess the level of altered visual size perception in people with schizophrenia are presented. Here we compare the performances in a visual sensory and perceptual test between a control group and an experimental group of people diagnosed with schizophrenia. We have been using paintings by Salvador Dalí and Rorschach plates to assess images size perception. In this transversal, ex-post-fact and quasi-experimental study we show differences between EG (Experimental Group) and CG (Control Group). Schizophrenics in-patients as compared to controls perceived sizes about 1.3 fold greater than healthy volunteers (p=0.006), thus showing that size perception is altered in schizophrenia. Together with previous results, this particular sensory test for size perception seems to be a useful assessment tool to evaluate the degree and severity of psychotic symptoms in prodromal schizophrenic states, and neuropsychiatric patients in general. It may help prevent acute crisis with proper, and most likely, lower dosages of medication.

AbstractIn this study, we compared visual pictorial size perception between healthy volunteers (CG) and an experimental group (EG) of people diagnosed with schizophrenia. We have been using paintings by Salvador Dalí and Rorschach plates to estimate visual pictorial size perception. In this transversal, ex post facto, and quasi-experimental study, we observed differences between EG and CG. Schizophrenic in-patients perceived sizes about 1.3-fold greater than healthy volunteers (p=0.006), implying that pictorial size perception is altered in some way in schizophrenia. Considering the present and previous results, this measurement of diameter size of first pictorial perception may be a useful estimate of some aspects of perceptual alterations that may be associated with psychotic symptoms in prodromal and acute schizophrenic episodes and other related mental states. Eventually, this may help in preventing people from evolving to acute episodes.

Abstract. This quasi-experimental study examined the effects of exposure to a computer game on arousal and subsequent task performance. After inducing a state of low arousal, participants were assigned to experimental or control conditions via self-selection. Members of the experimental group played a computer game for five minutes; subjects in the control group spent the same amount of time awaiting further instructions. Participants who were exposed to the computer game showed significantly higher levels of arousal and performed significantly better on a subsequent cognitive task. The pattern of results was not influenced by the participants' prior experience with the game. The findings indicate that mood-management processes associated with personal media use at the workplace go beyond the alteration of arousal and affect subsequent cognitive performance.

Caring for the persons with first episode psychosis is challenging and demanding. It may lead to the increased burden, expressed emotions among the caregivers. The numerous studies have shown that high burden and negative expressed emotions among caregivers can lead to early relapse in the patients with first episode psychosis. To evaluate the effects of the brief psychoeducation on the caregivers burden and expressed emotions. A quasi experimental - before and after with control group research design was adopted for the study. A total of 60 caregivers have participated in the study, of which 30 caregivers in experimental group and 30 caregivers in the control group. Family Burden Interview Schedule (Pai and Kapoor, 1981) and Attitude Questionnaire (Sethi et al., 1981) was used to assess caregiver's burden and expressed emotions. At end of the psychoeducation intervention, burden among caregivers and negative expressed emotions of the caregivers have significantly reduced. The positive expressed emotions have been increased. Study results demonstrates the importance of psychoeducation intervention in reducing the burden and negative expressed emotions.

The problem of this study is “Does Concept Oriented Reading Instruction (CORI) enhance students’ reading achievement?” The design of this study was quasi-experimental. The sample of this study was taken from the population by using purposive sampling. The experimental group consisted of 39 students while the control group consisted of 35 students. The data were collected by using two instruments; test and questionnaire. The test was given twice to each group in order to see whether or not there was significance difference of pretest and posttest either in experimental or control group and whether or not there was significance difference of experimental and control group in terms of their posttest score. To prove the hypothesis, the data from pretest and posttest of experimental and control group were analyzed by applying paired sample t-test and independent sample t-test. The calculation was run by using SPSS computer program. The result of the study shows there was significance difference of students’ reading achievement between experimental and control group. Besides, the use of CORI as reading strategies was proved as effective reading strategies to enhance students’ reading achievement.

Due to the emergence of computer education, AI education, the Internet of Things, big data, and technological wisdom, it is easy for students to be distracted when engaged in traditional education. Flipped teaching is a teaching strategy frequently used in colleges and universities. The focus of this research was conducted by a comparative analysis of the cognitive load between the experimental group and the control group through a quasi-experimental design for research with different learning methods and different classes. More specifically, flipped teaching was carried out with an experimental group, and traditional teaching a control group; they were observed at the same time, and 213 private university students participated in the experiment. The research proposes a practice of mixed teaching, carried out in a group communication behavior system, and enhancing the spirit of group interaction and learning through mobile devices. The core value of the research lies in (1) online learning, (2) group interaction, and (3) the learning load of the conceptual model. In addition, focus group interviews were used to provide feedback on participants’ cognition and emotions. The results indicate that there were differences in cognitive load between the two classes.

Kodály-inspired pedagogy enables students to participate effectively in a music course by engaging in active musical interactions with folk songs and melodies. The purpose of this study was to explore the effects of Kodály-inspired pedagogy on recorder performance and attitudes toward music of secondary school students. A quasi-experimental design was used in the study. The experimental group was taught using Kodály-inspired pedagogy and the control group using the general music teaching methods for 9 weeks. A two-way mixed-design analysis of variance (ANOVA) and content analysis were used to analyze the data. A Recorder Performance Grading Key, music course attitude scale, and open-ended questions were used to collect the data. Consequently, the findings indicated that Kodály-inspired pedagogy had a significant effect on the students’ recorder performance but the researchers could not find a significant effect on students’ attitudes toward the music course. Moreover, students in the experimental group reported improvement in their recorder performance and attitudes toward music education. The researchers recommended including information about the implementation of Kodály-inspired pedagogy in music teacher textbooks, providing in-service training for teachers to enable them to use Kodály-inspired pedagogy.

<b><i>Introduction:</i></b> A disturbed sense of self is frequently discussed as an etiological factor for delusion symptoms in psychosis. Phenomenological approaches to psychopathology posit that lacking the sense that the self is localized within one’s bodily boundaries (disembodiment) is one of the core features of the disturbed self in psychosis. The present study examines this idea by experimentally manipulating the sense of bodily boundaries. <b><i>Methods:</i></b> Seventy-three patients with psychosis were randomly assigned to either a 10-min, guided self-massage in the experimental group (EG) to enhance the sense of bodily boundaries or a control group (CG), which massaged a fabric ring. Effects on an implicit measure (jumping to conclusion bias; JTC) and an explicit measure (Brief State Paranoia Checklist; BSPC) of delusion processes were assessed. The JTC measures the tendency to make a decision with little evidence available, and the BSPC explicitly measures the approval of paranoid beliefs. <b><i>Results:</i></b> Patients in the EG showed a lower JTC (<i>M</i> = 4.11 draws before decision) than the CG (<i>M</i> = 2.43; Cohen’s <i>d</i> = 0.64). No significant difference in the BSPC was observed. <b><i>Discussion/Conclusion:</i></b> Our results indicate that enhancing the sense of body boundaries through a self-massage can reduce an implicit bias associated with delusional ideation and correspondingly support the idea that disembodiment might be a relevant factor in the formation of psychotic symptoms.

The purpose of this study was to implement a comprehensive teaching program based on the principles of Teaching Games for Understanding (TGfU) model and questioning, and to assess its consequences for students’ satisfaction of basic psychological needs, motivation, perceptions of ability and intention to be physically active during Physical Education lessons in primary education. A quasi-experimental design was utilized. Participants were 111 students from two different groups of fifth and sixth graders, all enrolled in one primary school. Participants were divided into experimental and control group. Experimental group experienced a TGfU unit, according to small side games and the questioning. Control group experienced a small side games unit, without questioning. Within-group results showed that experimental group students reported significantly higher mean scores in all dependents variables of the study, in both genders. Results showed that control group only reported significantly higher mean scores in intention to be physically active variable, also in both genders. The results demonstrate the need to implement didactic units under comprehensive pedagogical approaches to improve motivation and the intention to develop healthy lifestyle habits in female and male students. More researches are needed to support this evidence.
