Major research themes, concepts, methodologies, and phenomena in the psychology of perception are reviewed in the present paper with an eye to exploring its possible contributions to methodological as well as theoretical development in cognitive science are proposed in this paper:Computational, intentional-descriptive, and eclectic. An emphasis is placed on how to propose issues in the psychology of perception from cognitive science views.Also explored in detail are possible ways to promote fruitful interactions among several fields in cognitive science, e.g., artificial intelligence, perceptual-cognitive psychology, and neuro-science.One approach is to consider psychology of perception's basic concepts, methodologies, and phenomena that call for the attention of researchers in neighboring fields in cognitive science.Finally discussed is what perception researchers should do in adoptiong a much briader view of perceptual structure and processes, that is, a cognitive science view.

Aim: We aimed to examine the cross-sectional and longitudinal associations between sleep and work-related impaired cognitive and emotional functioning in police employees. Methods: This study included 410 participants (52% men) employed in a police district in Norway at baseline, of which 50% also participated in the study at 6 months later follow-up. The questionnaires included items measuring work schedule, sleep length, insomnia, as well as impaired cognitive and emotional functioning at work. Results: The results showed that insomnia was related to impaired work-related emotional functioning measured at baseline, and to impaired cognitive functioning measured at both baseline and follow-up. Sleep length and rotating shift work were not associated with future decline in cognitive or emotional functioning. Conclusion: Our study indicates that the relationship between insomnia and emotional functioning at work may be transient, whereas insomnia can be related to both immediate and future impaired cognitive functioning. Replication of the findings in larger samples is advised. The findings call for an emphasis on the prevention and treatment of sleep problems among police employees as a mean of maintaining and improving cognitive and emotional functioning at work, and thereby reducing the risk for impaired performance and negative health and safety outcomes.

The present study applied cognitive continuum theory to university environment in order to demonstrate that students' cognitive modes move along the continuum to be adaptive to the certain situation. This study also compared students' cognitive modes and the generally required modes in the university. The results showed that the students used corresponding cognitive modes to each subject even though they had different cognitive styles in general. It means that the students are adaptive to various tasks. And, the comparisons of the students' cognitive modes with the require4 modes in the university showed that the university tended to induce the students to use analytical cognitive modes. Therefore, the university faculty should be aware that they usually induce the analytical modes, and that they need to use various kinds of cognitive modes in order for the students to have adaptability and flexibility. However, the study did not demonstrate that the students would perform better when they fitted their cognitive modes into each subject.

Preliminary studies have claimed that short term fasting would negatively affect school performance and cognition. In contrast some other studies have reported not important decline in cognition and executive function as a result of fasting. Also limited attention was generally devoted to dietetic regimens, nutritional status and body weight. Yet neuroscience and neuro-cognitive aspects of acute hunger on the electroencephalogram and differences between obese and non-obese cases is not well understood. Hence, we decided to design and perform a case study in a more controlled situation similar to reality. Therefore, we performed several examinations including subjective tests (for eating status) and objective tests (cognitive tests such as Stroop effect and Sternberg search and electroencephalogram measures such as steady-state visual evoked potential and auditory steady-state responses) for an obese and a non-obese academic case before and after a simple breakfast. The results showed that the breakfast effects on the neuro-cognitive functions depend on either obesity status, nutritional status of the case or the type of cognitive task (visual or auditory). This paper would open a new insight to answer some important questions about the neuro-cognitive implications of fasting and feeding in obese and non-obese human cases.

The present study identified dimensions of cognitive styles that were concerned with individual differences in cognitive processes. The results provided support for Robertson's [36] theory of cognitive processes that are independent of task. An individual's first or initial cognitive strategy may be consistent across different tasks and therefore considered their style. However, an individual's cognitive style may change after interacting with the task during a number of trials, and lead to a strategy that is particular to the task.

본 연구에서 면대면과 CMC상황에서 기저율과 개별정보를 통합해야하는 과제를 집단으로 결정하는 과제를 수행한 후, 집단 구성원들은 자신의 의견과 집단의 의견에 관해 다른 확신 수준을 보임을 발견하였다. 면대면 집단의 구성원이었던 사람들은 자신은 기저율과 개별정보를 둘 다 적게 사용하였지만 자신의 집단은 이 두 가지 정보를 모두 많이 사용하였다고, 지각하였으며, CMC집단의 구성원이었던 사람들은 자신과 자신의 집단이 유사한 정도로 기저율과 개별정보를 사용하였다고 지각하였다. 본 연구에서는 면대면 집단 조건에서는 집단 극화가 발생하였지만, CMC집단의 경우에는 오히려 억제되는 결과를 보였다. 이는 기존의 연구에 비추어 볼 때, 토론 시간의 부족에 기인한 것으로 고려되어지며, 추가 연구를 통해 더 많은 시간이 주어질 때 이 두 집단간에 어떠한 차이가 발생하는지 알아보고자 한다.

A modifiedPosner cue-target paradigm in which neutral, positive and negative (threat) words were presented in peripheral location for cue was used to investigate the difference of engagement component of attention across emotional valence and anxiety level of participants. Results showed an interaction effect between anxiety level of participants and emotional valence of cue in valid trial. This indicates that the engage component of attention is not encapsulated and influenced by anxiety level of participant.

A comprehension-based computational model of pilot action planning called ADAPT is presented to model pilot performance in a flight simulation context. Individual pilots were asked to execute a series of flight maneuvers using a flight simulator, and their eye-scanning, control movements, and flight performance were recorded in a time-synched database. Computational models of each of the 25 individual pilots were constructed, and the individual models simulated execution of the same flight maneuvers performed by human pilots. The time-synched eye-scanning, control movements, and flight performance of individual pilots and their respective models were compared to test ADAPT's predictive validity.

The purpose of this study is to examine the effects of emotional arousal and cognitive load on pupil diameter during a lie detection interview. The guilty group (n = 30) committed a mock crime (i.e., stealing cash) and the innocent group (n = 30) performed a mission (i.e., sending a message) in the research assistant's office. After that, their pupil size was measured using a wearable eye-tracker during the interview. The interview questions were classified with the three cognitive load, three emotional arousal, and three neutral questions. The results indicate that the main effects of group and time were not significant, but the interaction between group and time was significant. It means that when answering cognitive load questions, the guilty group showed larger increase in pupil diameter than the innocent group. The present study suggests that inducing cognitive load is more effective than inducing emotional arousal during an interview when using pupil diameter as an index of deception, and it is expected to improve the accuracy of lie detection.

Objectives : The aim of this study was to investigate relationships between psychotic symptoms and cognitive functions in schizophrenia. Methods : The study group was composed of 36 schizophrenic patients. Positive, negative, and disorganization symptoms were assessed using the PANSS. Verbal, visuospatial, attention, memory, and executive functions were assessed using a battery of cognitive tests. Results : Correlation analysis between symptom vs. cognitive measures showed that (a) positive symptoms were significantly correlated with no cognitive measures, (b) negative symptoms were significantly correlated with all cognitive measures, and (c) disorganization symptoms were significantly correlated with executive and memory measures. Correlation analyses between symptom vs. cognitive factors showed that negative-disorganization factor is significantly correlated with executive-memory factor. Conclusion : Significant relationships were confined mostly to frontal symptoms vs. frontal cognitive functions. Thus, the relationships may be mediated mainly by variations in severity of frontal pathology among patients.
