Perceiving gaze from head and eye rotations: An integrative challenge for children and adults

Gaze is an emergent visual feature. A person's gaze direction is perceived not just based on the rotation of their eyes, but also their head. At least among adults, this integrative process appears to be flexible such that one feature can be weighted more heavily than the other depending on the circumstances. Yet it is unclear how this weighting might vary across individuals or across development. When children engage emergent gaze, do they prioritize cues from the head and eyes similarly to adults? Is the perception of gaze among individuals with autism spectrum disorder (ASD) emergent, or is it reliant on a single feature? Sixty adults (M = 29.86 years‐of‐age), thirty‐seven typically developing children and adolescents (M = 9.3 years‐of‐age; range = 7–15), and eighteen children with ASD (M = 9.72 years‐of‐age; range = 7–15) viewed faces with leftward, rightward, or direct head rotations in conjunction with leftward or rightward pupil rotations, and then indicated whether the face was looking leftward or rightward. All individuals, across development and ASD status, used head rotation to infer gaze direction, albeit with some individual differences. However, the use of pupil rotation was heavily dependent on age. Finally, children with ASD used pupil rotation significantly less than typically developing (TD) children when inferring gaze direction, even after accounting for age. Our approach provides a novel framework for understanding individual and group differences in gaze as it is actually perceived—as an emergent feature. Furthermore, this study begins to address an important gap in ASD literature, taking the first look at emergent gaze perception in this population.     

Stop the clock because I can’t stop: time pressure,but not monitoring pressure,impairs response inhibition performance

ABSTRACT

Psychological pressure can exert detrimental effects on cognitive tasks that depend on attentional control. However, the effect of psychological pressure on inhibitory cognitive processes has been relatively overlooked. The study purpose was to examine the effect of psychological pressure on response inhibition. In Experiment 1, participants (N?=?125) were assigned to a combined time and performance-based incentive pressure condition or control condition. In Experiment 2, participants (N?=?124) were allocated to a time pressure only or control condition. Participants (N?=?149) in Experiment 3 were assigned to either an explicit monitoring pressure condition in which their performance was video-recorded or control condition. Participants in all experiments completed a Go/NoGo Task to assess response inhibition performance. Pressure impaired performance in Experiments 1 and 2 but not Experiment 3. The results demonstrate that time pressure, but not explicit monitoring pressure, significantly impairs inhibition accuracy. These findings are consistent with the distraction theory of performance pressure.

Cardiovascular dysfunction related to threat, avoidance, and vigilant work: Application of event-related potential and critique

An integrative approach is suggested to track symbolically simulated work environment stressors, as an act to burden higher cortical function in the exposed groups. ERP would be made together with measurement of end organ stress responses as well as measurements of perceived conditions. Field studies would be the necessary complement. The following conclusions are culled from the reviewed literature: among the pilots, cardiovascular problems are the most important cause of loss of license in Europe and North America. Interactions with coworkers for air traffic controllers have been associated with cardiovascular disability. Comparing various degrees of heart disease severity among professional drivers, the IHD drivers showed the smallest N2 amplitudes and the greatest diastolic blood pressure reactivity. P300 target amplitude showed an inverse correlation with number of work hours behind the wheel. The IHD drivers were envisioned in a phase of disturbance of the selective attentional process. An interrelation has been found between Event-Related Slow Potential ERSP and midinterval heart rate acceleration associated with displeasure and arousal. A positive correlation has been found between the amplitude of the ERSP and ventricular arrhythmia rate in cardiac patients. Lowering of arrhythmia rate in response to antiarhythmic agents was associated with a significant attenuation of the ERSP. Either acceleration or deceleration is associated with the appearance of the late CNV to the aversive noise burst. There might be a “common generator behind both anticipatory heart rate responses and cortical events.” CNV might be related to frontally mediated stress mechanisms.     

Linguistic recovery after closed head injury

Recovery from acute aphasia after closed head injury was studied in 21 young adults at least 6 months after injury. Three profiles of scores were found using standardized language tests. Persistent expressive and receptive impairment was present in 6 patients who sustained severe diffuse brain injury resulting in global cognitive deficit. Residual expressive impairment, primarily of naming, was associated with mild diffuse brain injury though focal left-hemisphere injury was present in 3 of 6 cases. Patients who recovered to normal levels on all language tests generally had acute neurologic findings consistent with mild diffuse brain injury. Cranial computed tomography at the time of followup frequently disclosed ventricular enlargement.     

Religious Commitment and its Relation to Happiness among Muslim Students: The Educational Level as Moderator

This study examines the relationship between religiosity and level of happiness in an Islamic context among Muslim students studying at Malaysian universities. The determinants of happiness included in this research are positive attitudes, self-esteem, and other-esteem. Religiosity has long been considered as the main determinant in increasing happiness, and educational level strengthens its relationship. For this purpose, the researchers sampled 230 Muslim students aged 17–40 years studying at Malaysian universities in Kuala Lumpur, Malaysia. The study found a positive and significant correlation between religious commitment and level of happiness. Religious commitment also shows positive and significant correlations with positive attitudes, self-esteem, and other-esteem. The study also concludes that educational attainment moderates the relationship between religious commitment and happiness. Thus, religious commitment plays a very important role in increasing levels of happiness.

     

Effectiveness of Spiritual Components Training on Life Satisfaction of Persian Orphan Adolescents

This study was performed with the purpose of determining the effectiveness of spiritual components training on life satisfaction of Persian orphan adolescents. The study population was from female adolescents of two orphanages located in Kerman, Iran. They were randomly divided into two experimental and two control groups (each group including ten members). The experimental groups were received the spiritual training in ten sessions (spiritual training included components such as image of God, relationship with God, Tawwakul, searching for meaning during difficulties and pain), whereas the control groups were in the waiting list. Life satisfaction questionnaire was completed by one experimental and one control group before the training; and also after it, all four groups filled out the mentioned questionnaire. The analysis of covariance on the results revealed that spiritual components training had a significant positive effect on life satisfaction of the experimental groups in comparison with the control groups. Lastly, discussion, conclusion, some suggestions and directions were indicated.     

Language Learners’ Writing Task Representation and Its Effect on Written Performance in an EFL Context

The present study attempts to give an account of how students represent writing task in an EAP course. Further, the study is intended to discover if learners’ mental representation of writing would contribute to their written performance. During a 16-week term, students were instructed to practice writing as a problem solving activity. At almost the end of the term, they were prompted to write on what they thought writing task was like and also an essay on an argumentative topic. The results revealed that students could conceptualize the instructed recursive model of writing as a process-based, multi-dimensional and integrated activity inducing self-direction and organization while holding in low regard the product view of writing. The findings also demonstrated that task representation was related to the students’ writing performance, with process oriented students significantly outperforming the product-oriented ones. Also, it was found that task representation components (ideational, linguistic, textual, interpersonal) had a significant relationship with the written performance (\(\upbeta =0.59\); Sig.: 0.006). The study can have both theoretical and practical implications with regard to the factors involving the students’ writing internal processes and their effects on written performance.     

The effect of religiosity on quality of life in Muslim patients with heart failure: a study in Qom,the religious capital of Iran

Due to the low quality of life (QoL) in patients with heart failure, many researchers attempted to find new ways to improve the QoL in these patients. This study was conducted to determine the relationship between QoL and religious attitudes of patients with heart failure. In this cross-sectional study, 130 male and female patients with heart failure were selected based on the inclusion criteria. Data were collected using 36-item short form Quality of Life and structured Religious Attitude Questionnaires. The average age of subjects was 59.50?±?12.29; also, 52.3% of them were female. A significant relationship was observed between patients’ QoL and their religious attitudes in mental (p?=?.03) and general health (p?=?.04) dimensions, but religious attitude had no significant correlation with physical health dimension (p?=?.66) and the total score of QoL (p?=?.30). At the end, it was concluded that religious beliefs can improve patients’ quality of life.
