Effects of salience are short-lived

ABSTRACT— A salient event in the visual field tends to attract attention and the eyes. To account for the effects of salience on visual selection, models generally assume that the human visual system continuously holds information concerning the relative salience of objects in the visual field. Here we show that salience in fact drives vision only during the short time interval immediately following the onset of a visual scene. In a saccadic target-selection task, human performance in making an eye movement to the most salient element in a display was accurate when response latencies were short, but was at chance when response latencies were long. In a manual discrimination task, performance in making a judgment of salience was more accurate with brief than with long display durations. These results suggest that salience is represented in the visual system only briefly after a visual image enters the brain.     

The Relationships of Teacher Ethnic Discrimination,Ethnic Identification,and Host National Identification to School Misconduct of Turkish and Moroccan Immigrant Adolescents in Belgium

We focus on school misconduct and how ethnic teacher discrimination, ethnic identification, and host national identification are associated with school misconduct of male and female immigrant adolescents. Additionally, we verify the moderating role of ethnic identification and host national identification. The results show that discrimination and host national identification are related with the school deviance of immigrant adolescents. The relationship between discrimination and school deviance differs for male and female adolescents. Ethnic identification and host national identification only moderate the relationship of ethnic teacher discrimination and school delinquency for girls who experienced ethnic teacher discrimination on a frequent basis.     

Five types of personality continuity in childhood and adolescence

This study examines 5 types of personality continuity--structural, mean-level, individual-level, differential, and ipsative--in a representative population (N=498) and a twin and sibling sample (N=548) of children and adolescents. Parents described their children on 2 successive occasions with a 36-month interval using the Hierarchical Personality Inventory for Children (I. Mervielde & F. De Fruyt, 1999). There was evidence for structural continuity in the 2 samples, and personality was shown to be largely differentially stable. A large percentage had a stable trait profile indicative of ipsative stability, and mean-level personality changes were generally small in magnitude. Continuity findings were explained mainly by genetic and nonshared environmental factors.     

Attentional capture within and between objects

The present study addressed the question whether attentional capture by abrupt onsets is affected by object-like properties of the stimulus field. Observers searched for a target circle at one of four ends of two solid rectangles. In the focused attention condition the location of the upcoming target was cued by means of a central arrowhead, whereas in the divided attention condition, the target location was not cued. Irrelevant abrupt onsets could appear either within the attended or within the non-attended object. The results showed that in the focused attention condition, onsets ceased to capture attention irrespective of whether the onset appeared within an attended object or within a non-attended object.     

Prioritized selection in visual search through onset capture and color inhibition: evidence from a probe-dot detection task

Observers performed a preview search task in which, on some trials, they had to indicate the presence of a briefly presented probe-dot. Probes could be presented on locations corresponding to old or new elements and prior to or after the presentation of the new elements. After the presentation of the new elements, probes were generally detected faster on new than on old locations, indicating prioritized selection of new elements. Prior to the presentation of the new elements, probes were detected faster on new than on old locations only when old and new elements differed in color. These results suggest that prioritized selection of new elements is mediated not by visual marking but by onset capture. Additionally, observers may apply color-based inhibition.     

Relevance of the Tripartite Dimensions of Affect for Anxiety and Depression in Youth: Examining Sex and Psychopathology Status

Using a combined sample (N = 1,215) of referred children and children from the general population aged between 8 and 14 years, the present study addressed two research goals: First, latent mean differences (depending on the individual’s sex or psychopathology level) in anxiety, depression, Positive Affect (PA), Negative Affect (NA) and Physiological Hyperarousal (PH) were examined. Secondly, the structure of anxiety and depression was investigated from a tripartite model perspective in boys and girls with high versus low levels of psychopathology respectively. When relating the latent mean level differences in NA, PA, and PH with those in anxiety and depression, the results suggest that higher levels (depending on the individual’s sex and psychopathology status) of anxiety or depression are associated with higher levels of PH and lower levels of PA, whereas no consistent pattern was found between mean level differences in NA on the one hand and mean level differences in anxiety/depression on the other. Results further demonstrated that a better fit was obtained for the dual than for the unitary construct representation in boys or girls with high or low levels of psychopathology, thereby suggesting that a valid distinction can be made between anxiety and depression in children between 8 and 14 years old, irrespective of their sex or level of psychopathology. However, when looking at the structural relations of the dual construct representation of anxiety and depression with NA, PA and PH in each of the four groups separately, it became evident that the PH and PA tripartite dimensions could not account for the unique aspects of anxiety and depression respectively. Moreover, PH rather than NA was found to be common for anxiety and depression.     

Stigma and Client Satisfaction in Mental Health Services

Numerous studies have revealed that stigmatization of persons with mental health problems has a large array of negative consequences. One outcome that has been largely neglected is client satisfaction. In this empirical study, the link between 3 types of stigma experiences and client satisfaction is explored in a sample of clients (N = 741) of professional mental health services in Belgium. This relationship is compared with the link between stigma and general life satisfaction; and the role of the self‐concept in these relationships is explored. The results reveal that the association depends on the dimension of stigma under study. The findings stress the importance of studying multiple dimensions of stigma experiences, in addition to multiple outcomes.     

The influence of a scene preview on eye movement behavior in natural scenes

Rich contextual and semantic information can be extracted from only a brief presentation of a natural scene. This is presumed to be activated quickly enough to guide initial eye movements into a scene. However, early, short-latency eye movements in natural scenes have been shown to be dependent on the salience distribution across the image (Anderson, Ort, Kruijne, Meeter, & Donk, 2015). In the present work, we manipulated the salience distribution across a natural scene by changing the global contrast. We showed participants a brief real or nonsense preview of the scene and examined the time-course of eye movement guidance. A real preview decreased the latency and increased the amplitude of initial saccades into the image, suggesting that the preview allowed observers to obtain additional contextual information that would otherwise not be available. However, the preview did not completely override the initial tendency for short-latency saccades to be guided by the underlying salience distribution of the image. We discuss these findings in the context of oculomotor selection based on the integration of contextual information and low-level features in a natural scene.
