Macro- and microlevel factors related to sense of community: The case of temporary neighborhoods in Israel

This study examines macro and micro factors influencing the development of sense of community (Davidson & Cotter, 1980) in two different populations (immigrants and veterans) in new temporary neighborhoods in Israel. At the macrolevel, the major factors examined were population size, population density, number of dwelling units in the site, urbanity of the area, ethnic heterogeneity, and peripheriality of the region. Three kinds of variables were examined on the microlevel: (a) personal attitudes: evaluation of the dwelling unit and satisfaction with public services; (b) social networks; and (c) sociodemographic characteristics. Data were collected from 242 immigrants from the former USSR and from 60 Israeli veterans, residing in 5 different sites. Two different patterns of predictors of sense of community emerged in the two different samples. In the veteran sample, only one macrolevel variable entered the stepwise analysis equation: the number of dwelling units in the site. In the immigrant sample, three significant microlevel factors entered the equation: evaluation of the dwelling unit, external network, and age. The data thus suggest that the major determinant factors underlying sense of community vary for different groups of people. The paper is based on a study initiated and financed by the Ministry of Housing and Construction, the Unit of Social Policy, Israel.     

Gender differences in apparent motion perception.

Distance disparity is a strong cue to element correspondence in apparent motion. Using a 2-AFC paradigm we have previously shown that shape similarity also plays a role. We now demonstrate a small gender difference in these effects: women are more sensitive to distance disparity, whereas men are more sensitive to differences in shape. Furthermore, in the competing presence of a shape cue, women's sensitivity to distance decreases while men's sensitivity is unaffected. These observations may be related to putative gender differences in the 'form' and 'motion-spatial relations' cortical pathways.     

Asymmetric interactions in the processing of the visual dimensions of position, width, and contrast of bar stimuli.

The processing of different dimensions of a single stimulus may be either integral or separable. Dimensions are called integral if correlated variation of one improves discrimination on the basis of the other and random variation of one interferes with discrimination on the basis of the other. For separable dimensions on the other hand, subjects can attend to one dimension and disregard variations in the other. These discrimination tests were used to find the interactions between the processing of the visual dimensions of position, width, and contrast of a light bar stimulus. The relations between these dimensions were found to be asymmetric: judgments of position and width are independent of contrast variations, but variations in these dimensions influence contrast discriminations. Furthermore, position variations influence width judgements more than vice versa. The data were analyzed for repetition effects, and it was found that this model is not sufficient to explain all the interaction phenomena. The asymmetries found may be related to the different ways these dimensions are mapped onto cortical neuron responses.     

Interactions in the discrimination and absolute judgement of orientation and length

An asymmetric model is described for interactions in the perception of two dimensions (length and orientation) of a single visual stimulus. Two methods were used to test these interactions, and models for the interpretation of the possible outcomes of these tests are discussed. A length discrimination task showed facilitation (decreased reaction time) when orientation was covaried with length, and interference (increased reaction time) when random orientation variation was introduced. A smaller effect was seen when length was varied in an orientation discrimination task in a correlated or random fashion. Analysis of sequential effects showed that reaction times are fastest on repetition trials and are slowed by either the need to change the response or the need for additional sensory processing. With the second method, it was found that the amount of information transmitted in the estimation of orientation was not affected by the introduction of the redundant dimension of length, but that there was a significant gain in the amount of information transmitted in the estimation of length by the addition of the redundant dimension of orientation. It is concluded that orientation is probably a perceptual primitive of the visual system whereas length is a computed variable.     

In competitive interaction displays of red increase actors' competitive approach and perceivers' withdrawal

Colors carry meaningful psychological signals. We hypothesized that the color red serves as a powerful cue in competition, affecting both actors and perceivers. Using simplified poker games we investigated the psychological meaning of color in competitive interaction, by examining how the color of chips (red vs. blue or white) used by participants or their competitors affected behavior. Although chip color was objectively unrelated to the chips' value or competitors' strength, perceiving competitors using red chips renders competitors more intimidating, which leads perceivers to withdraw. Furthermore, actors who used red chips felt more dominant, which led them to enhanced competitive approach. Displaying red thus makes actors feel stronger and increases competitive approach; perceivers of displays of red in competitors feel intimidated and withdraw from competing.     

Perceptions and attitudes to sexual harassment: an examination of sex differences and the sex composition of the harasser–target dyad

This study examines the role of sex in determining attitudes toward sexual harassment (SH) and perceptions of SH, and studies the extent to which attitudes toward SH predict perceptions of SH by sex. All informants (146 men and 160 women) completed three questionnaires: personal information; perceptions of SH, including cases with variations on the perpetrators and victims' sex; and attitudes toward SH, with a male, female, or unspecified victim. The findings point to significant sex differences in the perception of behaviors as SH. Women were less tolerant of SH regardless of the victim's sex. In all cases, less tolerant attitudes toward SH predicted a stronger perception of behaviors as manifesting SH. In addition, women tended to perceive male harasser/male target behaviors as SH more than men.     

Postwar Recovery to Stress Symptoms Ratio as a Measure of Resilience,Individual Characteristics,Sense of Danger,and Age

This study maintains that postwar resilience should be defined by the proportion of recovery from war adversity and level of postwar symptoms. We hypothesize first that four resilience-promoting factors will predict this measure of resilience. Second, these associations will be mediated by sense of postwar danger. Third, war-afflicted older people will be comparable to younger people on these variables. The sample included 829 Israeli adults who experienced the 2006 second Lebanon war. Results that have generally supported these hypotheses have been discussed in terms of the definition of resilience, the role of sense of danger in postwar adjustment, and the resilience of older people to war.     

The self-protective altruist: terror management and the ambivalent nature of prosocial behavior

Three studies examined the hypothesis that mortality salience (MS) will increase prosocial behaviors when the prosocial cause promotes terror management processes. However, when the prosocial cause interferes with these processes, MS will reduce prosocial behavior. In Study 1, following a MS procedure, participants indicated their willingness to donate money to charity or to donate to an organ donation organization. In Study 2, a research assistant randomly distributed fliers with reminders of death or back pain, and another research assistant solicited participants' assistance from either a charitable fund booth or an organ donation booth. Study 3 examined the impact of MS on helping a wheelchair-bound confederate or a walking confederate. The results indicated that MS increased charitable donations and increased help to a walking confederate. However, MS significantly decreased organ donation card signings and decreased help to a wheelchair-bound confederate. The discussion examines the tension between personal fear and worldview validation.
