The Effects of a Common In‐group Prime on Intentions to Help Indigenous and Homeless Australians

The article reports on research designed to test Australian attitudes towards helping impoverished members of the Australian society, in particular, indigenous and homeless people. Australian university students completed a questionnaire to measure their attitudes towards helping homeless and indigenous people under conditions that primed a common Australian identity. The findings showed that priming an inclusive identity led to relatively stronger intentions to help indigenous Australians but not homeless people. It was also found that participants preferred to endorse more autonomy than dependency help to both indigenous and homeless Australians. Whereas the findings indicate that helping intentions towards those living with poverty may be accentuated by priming a common in‐group, they also imply that helping attitudes vary with the type of help being sought and the way people perceive the cause of someone's poverty.     

Group Status and Hierarchy Legitimacy Effects on Effort Versus Ability Attributions for Ingroup and Outgroup Failures

Previous research has shown that people have a tendency to explain various outcomes in ways that favour their ingroup. However, there is also some evidence that this tendency may be moderated by perceptions of group status and hierarchy legitimacy. In this study, we experimentally test the combined effects of group status and hierarchy legitimacy on effort and ability attributions for ingroup and outgroup failures. It was predicted that participants assigned to an illegitimately low status condition would attribute ingroup but not outgroup failure more to a lack of effort than ability. Conversely, participants assigned to a legitimately high status group were expected to attribute ingroup but not outgroup failure more to a lack of effort than ability. Results supported these predictions and also showed outgroup failure was attributed more to a lack of effort than ability when ingroup status was either legitimately low or illegitimately high. We conclude that intergroup attributions are constrained by perceptions about relative group status and the legitimacy of the status hierarchy.     

Delboeuf “illusions” of circle size induced via photoflash-generated afterimages

Generating an inducing figure by photoflash led to underestimation of the size of a luminous outline test circle in a nonluminous surround. As the afterimage of the inducing circle decayed, judged size of the test circle attained true size. The more intense inducing flash produced a longer lasting perceptible afterimage but no alteration in amount of test-circle underestimation as a function of time. The type of inducing configuration (outer concentric circle, nonconcentric circles, arcs) proved to have no differential effect. In the absence of an inducing figure, subjects make veridical judgments.     

The effects of personal and collective mortality salience on individualism: Comparing Australians and Japanese with higher and lower self-esteem

The cross-cultural generality of terror management theory was examined in Australia and Japan. Based on previous research suggesting that individualism is stronger in Australia than in Japan, mortality salience was predicted to enhance individualism in Australia, but to reduce it in Japan. The results supported this prediction. Consistent with the theory, the cultural pattern of worldview defense was found only among Australians and Japanese with low self-esteem. We also found preliminary evidence that collective mortality (death of one’s in-group) has a greater impact than personal mortality (personal death) in Japan. Although the cultural worldview and self-esteem may serve terror management functions in both cultures, there may be differences between cultures in the type of mortality that produces the greatest levels of anxiety and the manner in which a given worldview is used to cope with anxiety about mortality.     

Picture perception is array-specific: viewing angle versus apparent orientation

The amount that a pictured lattice appears to be swung from its frame changes with subjects' viewpoint, in contrast with previous experiments using insufficient range of rotation. Also, this effect is shown to be independent of the physical slant of the picture surface, though not necessarily of border-shape information. Analysis of depicted headings which rotate with viewpoint, with respect to the picture plane, although the angle between these headings in virtual space hardly changes, relates these data to specific geometric properties of the perspective array as seen from the different viewpoints. Data show differential rotation of differently oriented features within a single depicted object, in a way that is dependent on task instructions. It is proposed that in picture perception, contradictory cues are resolved by combination.     

Spatial reversal as a measure of executive functioning in children with autism

The purpose of this experiment was to compare the executive functioning performance of children with autism with chronological- and verbal-matched controls in a spatial-reversal task. Three groups of children participated in this experiment. One group was identified as having autism (7 boys), the 2nd group contained 7 typically developing children (6 boys, 1 girl) who were matched to the 1st group based on their verbal performance, and the 3rd group contained 7 typically functioning children (6 boys, 1 girl) matched to the 1st group based on chronological age. Each group was given a spatial-reversal task containing 2 problems. In the 1st problem, children selected a toy on a particular side in a pair. In the 2nd problem, the contingencies were reversed such that children were to choose the toy on the opposite side. Children with autism generally performed worse than comparison groups as indicated by their overall higher rate of errors. However, these results must be qualified by considering the performance for each problem: Errors for the children with autism were infrequent during the 1st problem but increased in the 2nd, whereas errors for comparison children showed the opposite pattern. When these results from the spatial-reversal task were interpreted from the perspective of hypothesis-testing theory, the executive functioning deficiency of children with autism was found to involve the selection and testing of stereotypic response sets that were not likely to be revised or changed flexibly according to feedback from the environment or the demands of the task.     

Grasping movement plans

Despite the great amount of research that has been done regarding the time it takes to move the hand to targets of varying distances and widths, it is unclear whether target distance and width are both represented in movement plans prior to movement initiation. We addressed this question by studying performance in an object manipulation task. Our participants reached out and took hold of a familiar object (a bathroom plunger) to move it to wide or narrow targets of varying heights. Grasp heights on the plunger were additively affected by target height and target width, suggesting that both factors were taken into account by participants prior to moving the plunger from its initial position. Another factor we manipulated was the width of the base from which the plunger was lifted on its way to its next position. This factor also affected grasp heights, but no more so than target widths. The latter result contradicts the view that movement starts are planned in more detail than movement ends, as might be expected from the fact that movement starts come sooner. Together, our results suggest that forthcoming movements are planned in considerable detail. A surprising methodological implication of this study is that recording how people prepare to move can reveal as much—or in some cases more—about what they have planned than can recording their subsequent movements.     

Finding a picture’s station point: Reconstructing virtual space when the usual way will not work

University of Maryland University College, Asian Division, Yokota, Japan To reconstruct the space represented in a photograph or other picture made in perspective, its vantage point, or station point, must first be found, and the usual way to find this point requires that the picture show a rectilinear grid or at least one grid element. The station points of the many pictures that lack any such grid may be found by a new method presented here, on two conditions: The line of sight, from the original observer to the scene, must be determinable, and, within the scene, there must be at least one quantitative spatial relation involving both a depth extent and an extent laterally (breadth or height), the 3-D value of which is known. Researchers may use either the graphic (projective) or the computational (algebraic) procedures of this new “sightline” method, in reconstructing the spaces of pictures used as stimuli.
