Family boundary characteristics,work–family conflict and life satisfaction: A moderated mediation model

Although work–family border and boundary theory suggest individuals' boundary characteristics influence their work–family relationship, it is largely unknown how boundary flexibility and permeability mutually influence work–family conflict and subsequent employee outcomes. Moreover, the existing work–family conflict research has been mainly conducted in the United States and other Western countries. To address these gaps in the work–family literature, the present study examines a moderated mediation model regarding how family boundary characteristics may influence individuals' work–family conflict and life satisfaction with a sample of 278 Chinese full‐time employees. Results showed that employees' family flexibility negatively related to their perceived work interference with family (WIF) and family interference with work (FIW), and both these two relationships were augmented by individuals' family permeability. In addition, WIF mediated the relationship between family flexibility and life satisfaction; the indirect effect of family flexibility on life satisfaction via WIF was stronger for individuals with higher family permeability. The theoretical and managerial implications of these findings are discussed.     

Elongation and enclosure

Previous work suggested that elongation, horizontal area, and the boundary material might influence impressions of enclosure. This article describes an experiment in which these three factors were crossed. Ratings of open/enclosed by 15 respondents on 16 plazas indicated that the elongation ratio (range: 1:1 up to 1:1.8) had the strongest effect on impressions of enclosure (18% of variance). Horizontal area (12.25 m2 vs 49 m2) area accounted for 3% of variance. The amount of variance attributable to boundary material (plants vs walls) was an order of magnitude smaller (0.3%).     

Group boundary permeability moderates the effect of a dependency meta‐stereotype on help‐seeking behaviour

Previous studies have found that when low‐status group members are aware that their in‐group is stereotyped as dependent by a specific out‐group (i.e. a dependency meta‐stereotype is salient), they are reluctant to seek help from the high‐status out‐group to avoid confirming the negative meta‐stereotype. However, it is unclear whether low‐status group members would seek more help in the context of a salient dependency meta‐stereotype when there is low (vs. high) group boundary permeability. Therefore, we conducted two experiments to examine the moderating effect of permeability on meta‐stereotype confirmation with a real group. In study 1, we manipulated the salience of the dependency meta‐stereotype, measured participants' perceived permeability and examined their help‐seeking behaviour in a real‐world task. Participants who perceived low permeability sought more help when the meta‐stereotype was salient (vs. not salient), whereas participants who perceived high permeability sought the same amount of help across conditions. In study 2, we manipulated the permeability levels and measured the dependency meta‐stereotype. Participants who endorsed a high‐dependency meta‐stereotype sought more help than participants who endorsed a low‐dependency meta‐stereotype; this effect was particularly strong in the low‐permeability condition. The implications of these results for social mobility and intergroup helping are discussed.     

Inaccurate representation of the ground surface beyond a texture boundary

The sequential-surface-integration-process (SSIP) hypothesis was proposed to elucidate how the visual system constructs the ground-surface representation in the intermediate distance range (He et al, 2004 Perception 33 789-806). According to the hypothesis, the SSIP constructs an accurate representation of the near ground surface by using reliable near depth cues. The near ground representation then serves as a template for integrating the adjacent surface patch by using the texture gradient information as the predominant depth cue. By sequentially integrating the surface patches from near to far, the visual system obtains the global ground representation. A critical prediction of the SSIP hypothesis is that, when an abrupt texture-gradient change exists between the near and far ground surfaces, the SSIP can no longer accurately represent the far surface. Consequently, the representation of the far surface will be slanted upward toward the frontoparallel plane (owing to the intrinsic bias of the visual system), and the egocentric distance of a target on the far surface will be underestimated. Our previous findings in the real 3-D environment have shown that observers underestimated the target distance across a texture boundary. Here, we used the virtual-reality system to first test distance judgments with a distance-matching task. We created the texture boundary by having virtual grass- and cobblestone-textured patterns abutting on a flat (horizontal) ground surface in experiment 1, and by placing a brick wall to interrupt the continuous texture gradient of a flat grass surface in experiment 2. In both instances, observers underestimated the target distance across the texture boundary, compared to the homogeneous-texture ground surface (control). Second, we tested the proposal that the far surface beyond the texture boundary is perceived as slanted upward. For this, we used a virtual checkerboard-textured ground surface that was interrupted by a texture boundary. We found that not only was the target distance beyond the texture boundary underestimated relative to the homogeneous-texture condition, but the far surface beyond the texture boundary was also perceived as relatively slanted upward (experiment 3). Altogether, our results confirm the predictions of the SSIP hypothesis.     

Framing effects and the reversed Müller-Lyer illusion.

The enclosure hypothesis of the reversed Müller-Lyer illusion was examined in three experiments. In Experiment 1, the ingoing- and outgoing-wings forms of the illusion were measured separately, as a function of the size of the gap between the ends of the shaft and the apices of the wings. In Experiments 2 and 3, the effects of a square frame and of complete and amputated versions of a rectangle on the perceived length of an enclosed horizontal line were examined. For all non-Müller-Lyer illusion figures, an inverted U-shaped function describes the relationship between illusion magnitude and the length of the test line. The peak overestimation of the test line's length was obtained when the ratio of total figure length to test line length was about 3:2. Taken together, the results of the three experiments suggest that the reversed Müller-Lyer illusion can be explained within current theoretical frameworks, such as assimilation theory, without recourse to a special factor of enclosure.

Relationship of personal space to body-image boundary definiteness

The role of body-image boundary definiteness as a mediating personality variable in interpersonal spatial behavior under conditions of perceived threat was investigated in this study. It was hypothesized that personal space would be positively correlated with body-image boundary definiteness. The Comfortable Interpersonal Distance scale and the Holtzman Inkblot Technique were group administered to 34 male and 43 female college students. Significant positive correlations were obtained for both sexes when approached by a male stranger but not when approached by a female stranger. Results were discussed in terms of level of perceived threat.     

Judgments of visually perceived eye level (VPEL) in outdoor scenes: effects of slope and height

When one looks up a hill from below, its peak appears lower than it is; when one looks at a hill across a valley from another peak, the peak of that hill appears higher than it is. These illusions have sometimes been explained by assuming that the subjective horizontal is assimilated to the nearby slope: when looking up a slope, the subjective horizontal is raised, diminishing the height of the peak above the subjective horizontal, and making the peak appear lower than it is. When looking down a slope towards another hill, the subjective horizontal is lowered, increasing the height of that hill above the subjective horizontal, and making its peak appear higher than it is. To determine subjective horizontals we measured visually perceived eye levels (VPELs) in 21 real-world scenes on a range of slopes. We found that VPEL indeed assimilates by about 40% to slopes between 7 degrees downhill and 7 degrees uphill. For larger uphill slopes up to 23 degrees, VPEL asymptotes at about 4.5 degrees. For larger downhill slopes, the assimilation of VPEL diminishes, and at 23 degrees is raised by about 1 degree. These results are consistent with the assimilation explanation of the illusions if we assume that steep downhill slopes lose their effectiveness by being out of view. We also found that VPEL was raised when viewing from a height, in comparison with ground-level views, perhaps because the perceived slope increases with viewing height.     

Integration of stimulus dimensions in perception and memory: composition rules and psychophysical relations

A series of five experiments used the method of magnitude estimation to assess how height and width are integrated in perceptual and in memorial judgments of area. Separate groups of subjects estimated the areas of perceived or remembered rectangles produced by a symmetrical 4 X 4 factorial design of height and width. Additional independent groups of observers made area judgments, based on special mixes of perceptual and memorial information referring to the height and width components of the to-be-judged rectangles. Both perceptual and memory data obeyed the bilinear interaction prediction of the normative multiplicative model. The relation between perceived and actual area as well as the relation between remembered and actual area could both be described by a compressive power function, with the exponent being reliably smaller for remembered than for perceived area. These results seem to imply a principle of integration rule invariance across perceptual and memorial estimates of a given set of stimuli, in conjunction with characteristically different valuation operations.     

Intergroup aggression: its predictors and distinctness from in-group bias

Investigated predictors of intergroup aggression and its relations to in-group bias. In a questionnaire, 156 Israeli adults reported perceptions of their own religious group and of the ultraorthodox Jewish out-group and expressed aggression toward the ultraorthodox (opposing institutions that serve their needs, supporting acts harmful to them, and opposing interaction with them). Respondents showed in-group favoritism in trait evaluations, but this bias was unrelated to aggression. Perceived inter-group conflict of interests, the postulated motivator of aggression, predicted it strongly. The effects of conflict on aggression were partially mediated by 2 indexes of dehumanizing the out-group (perceived value dissimilarity and trait inhumanity) and by 1 index of probable empathy with it (perceived in-group-out-group boundary permeability). These variables related to aggression more strongly among persons who identified highly with their in-group. The variables also mediated the effects of religious group affiliation on aggression. The value dissimilarity finding supports derivations from belief congruence theory.     

权力概念垂直空间隐喻表征激活的条件

本研究通过三个实验考察权力概念垂直空间隐喻表征激活的条件。实验1发现,在权力判断任务中,具有直接权力关系的相关词对和间接权力关系的无关词对都可以激活隐喻表征。实验2使用相关判断任务,只有相关词对激活了隐喻表征。这说明对词汇进行语义加工并理解权力关系是激活隐喻表征的重要条件。实验3引入水平方向干扰,并将被试的注意转移到干扰信息上,结果仍然出现了隐喻一致性效应,表明垂直空间线索不是隐喻表征激活的必要条件。     

Extent,multiplying, and proportionality rules in children's judgments of area

The study examined children's use of multiplying and proportionality rules in judgments of area. In two experiments children judged the area of rectangles. Seven-year-olds used linear extent as an index of area. Eight- and nine-year-olds replaced the extent rule with the height × width rule. In a third experiment 8-through 11-year-olds were presented with a rectangle and a horizontal line representing the width of a second rectangle. Children were asked to indicate the height that would make the second rectangle equal in area to the first. The correct response was proportional to the product of the ratio of the widths of the two rectangles and the height of the first rectangle. Graphical and statistical analyses indicated that children applied the ratio rule to these judgments. The implications for Piaget's theory of cognitive development were discussed.     

Induced movement as nonveridical resolution of displacement ambiguity: Effect of enclosure and number of field elements

Four experiments on induced movement and induced stationariness are described. Experiments 1 and 2 showed that mere enclosure of a stationary spot in a moving frame does not necessarily result in induced movement. Nor does enclosure of a moving spot in a stationary frame necessarily result in perceived real movement of the spot. Duncker’s principles of enclosure is thus called into question. Two further experiments showed that both induced and perceived real movement of a spot are much more frequent when the frame is replaced by either two or more similar spots which enclose or flank the target spot. It can be concluded that the principle of enclosure obtains when the reference field consists of more than one element which move or remain stationary together. When such a field moves, it is the single, enclosed element which appears to move while the field itself appears stationary.     

Eyeheight-scaled information about affordances: a study of sitting and stair climbing

Previous work has shown that both the perceived and actual critical (maximum) heights of surfaces that afford "sitting on " and "climbing on" can be expressed as constant proportions of each actor's leg length. The current study provides evidence that these judgments of critical action boundaries are based on an existing source of size and distance information that is already scaled with reference to the actor's eyeheight. In Experiment 1 changes in judgments of "perceived eyeheight" (an index of the intrinsic scalar) as a function of viewing distance were shown to be highly correlated with changes in the maximum height that was perceived to afford sitting on or climbing on. In Experiments 2 and 3 observers wore 10-cm blocks and made judgments about whether the heights of various surfaces afforded sitting or climbing. The use of eyeheight-scaled information as the basis for their estimates predicted the obtained pattern of errors in these judgments. With a modicum of experience wearing the blocks, however, observers were able to retune accurately their critical action boundary to a degree that would not have been predicted from their consistent overestimation of the height of the block on which they were standing. These results have implications for understanding how observers obtain information about their specific action boundary.     

A biodynamic basis for perceived categories of action: a study of sitting and stair climbing

Actors must determine whether the properties of the surface layout are sufficient to meet their specific requirements for performing an action. Warren's (1984) study of bipedal stair climbing has demonstrated the significance of intrinsic, body-scaled measures of environmental properties for defining perceptual categories relevant to action. Whereas the absolute measure of the perceptual boundary between "climbable" and "not climbable" varied according to the actor's size and mass, the perceived boundary was a constant proportion of each actor's leg length. Our current study examined the perceived maximum seat height (SHmax) for the act of sitting. Experiment 1 delineated the range of surface heights that were perceived to afford sitting on. When expressed as a function of each person's leg length (L), SHmax was remarkably stable across individuals. Unexpectedly, it was quite close to the maximum riser height determined by Warren. Experiment 2 examined whether this similarity reflected a common biodynamic requirement, since climbing and sitting require actors to lift their center of gravity above the surface of support. Perceived critical heights were obtained for both acts using the same methods and apparatus. The perceived maximum heights for each act were virtually identical. These findings are consistent with the possibility that the information used in determining critical action boundaries is already scaled with reference to some physical dimension of the actor.     

Surface location and enclosure

This research addressed the issue of whether impressions of enclosure were more strongly influenced by amount of view covered by vertical boundaries (H1) or the presence of a boundary overhead (H2). There were three studies with totals of 48 stimuli and 142 respondents. Stimuli were balconies, swamps, and space stations. Effect sizes were reported for variables of boundaries below, in front of, and at the observers' sides, as well as amount of view covered by any boundary regardless of location with respect to the observer. Judged enclosure correlated at r =.80 for amount of view covered by vertical boundaries and r =.42 with the presence or absence of boundaries overhead, indicating that enclosure is more strongly related to vertical rather than overhead boundaries (alpha< .001).     

Status differences and in-group bias: a meta-analytic examination of the effects of status stability, status legitimacy, and group permeability.

This work examines the moderating effects of status stability, legitimacy, and group permeability on in-group bias among high- and low-status groups. These effects were examined separately for evaluative measures that were relevant as well as irrelevant to the salient status distinctions. The results support social identity theory and show that high-status groups are more biased. The meta-analysis reveals that perceived status stability, legitimacy, and permeability moderate the effects of group status. Also, these variables interacted in their influences on the effect of group status on in-group bias, but this was only true for irrelevant evaluative dimensions. When status was unstable and perceived as illegitimate, low-status groups and high-status groups were equally biased when group boundaries were impermeable, compared with when they were permeable. Implications for social identity theory as well as for intergroup attitudes are discussed.     

Family boundary ambiguity: a new variable in family stress theory

The variable, degree of family boundary ambiguity, is increasingly being used in family research to describe and predict the effects of family membership loss and change over time. Boundary ambiguity is defined as the family not knowing who is in and who is out of the system. The family may perceive a physically absent member as psychologically present or a physically present member as psychologically absent. In either case, the family boundary is ambiguous. This review is presented to clarify the meaning of boundary ambiguity and to explore its scope and application as a variable. We focus here on (a) the process of theory development, inductive and deductive, by which the construct of boundary ambiguity was identified and validated as a continuous variable within family stress theory; (b) the historical antecedents of the construct; and (c) the interrelationships of the variable with other factors related to stressed families.     

Evidence for a boundary effect in roll vection

Large circular displays rotating around the line of sight produce an illusion in which the seen orientation of the true vertical is shifted in a direction opposite to the display’s motion. Two experiments were performed to determine whether the magnitude of this illusory tilt is a function of the area of display elements, of their boundary length, or of their spatial frequency. In Experiment 1, 12 subjects viewed each of nine displays across which the number and area of the circular elements were independently varied. Three of the displays were equated for the area of their elements. The results suggested that tilt magnitude and onset latency could be explained by a boundary length effect. A second experiment tested eight subjects on two displays, equated for element boundary length but differing in the spatial frequency of the elements. The displays produced closely similar illusory trite corroborating the view that, within broad limits, element boundary length—and not spatial frequency or area—determines the size and onset latency of illusory tilt. A third experiment confirmed previous research in finding greater tilt and more rapid onset with more peripherally projected displays.
