Ethnicity, socioeconomic background, and psychosis-proneness in a diverse sample of college students

A sample of 915 college students completed the Perceptual Aberration, Magical Ideation, and Schizotypal Personality Scales. No statistically significant differences were found between African-American (n=209) and European-American (n=591) students on these measures, except on the Perceptual Aberration Scale (p<0.01). Additional analyses revealed that this difference was mediated by the subjects’ gender and socioeconomic background. The results of the present study are consistent with previous studies that have examined the mediating role of socioeconomic background in the performance of African-Americans on the Minnesota Multiphasic Personality Inventory (MMPI) and the Millon Clinical Multiaxial Personality Inventory (MCMI) and confirm that differences on schizotypy measures are best interpreted in the context of the sociocultural background of the subjects.     

Judging toy breakers: Gender stereotypes have devious effects on children

Second-grade children listened to short stories about male or female children who accidentally broke neutral and sex-appropriate or opposite-sex toys. Children then rated the severity of punishment due to each toy breaker and provided justifications for their ratings. The justifications were coded for citing intentionality (or lack thereof) and toy ownership (or lack thereof). No differences were found between boys and girls in the punishment severity ratings of targets of either gender who broke neutral toys. In the punishment severity ratings of toy breakers of sex-appropriate and opposite-sex toys, gender stereotype effects were found only for girls; they suggested more severe punishment for toy breakers of opposite-sex toys, irrespective of their gender. The citation of toy ownership was found to be a significant variable in boys’ nonuse of gender stereotypes in their punishment severity ratings; with the impact of toy ownership removed, gender differences in punishment severity ratings were eliminated. Although the citation of intentions did not influence the punishment severity ratings of either boys or girls, boys referred to intentions primarily in same-sex targets. The data illustrate both the direct and the devious impact of gender stereotypes on children’s social cognitive processes.

We would like to thank Dale Miller for his helpful comments on a previous version of this paper.     

Effect of the Commander's Ethnic Origin on Ethnic Attitudes of Israeli Soldiers1

This study examined the effect of the squad commander's ethnic origin on subordinates' interethnic attitudes. Thirty squads of recruits, serving in the Israeli army, took part in the study. Seventeen of the squad commanders were of Middle Eastern origin, and 13 of Western origin. Each squad contained both Middle Eastern and Western soldiers. Toward the end of the basic training, subjects responded to a series of questionnaires assessing their willingness to share various activities with both squad members and soldiers they did not know, as well as their evaluation of them. The results show- that those serving under a Western commander displayed more willingness to interact with Western than with Middle Eastern others. Subjects serving under a Western commander also evaluated more positively Western than Middle Eastern non-familiar soldiers. Those serving under a Middle Eastern commander displayed more willingness to share activities with Middle Eastern than with Western non familiar soldiers. They also evaluated nonfamiliar soldiers from Middle Eastern origins more positively than Western soldiers. The discussion focuses on the distinction between familiar and non familiar targets, and the role of “equal-status hypothesis” and “expectation states theory.”     

A computer terminal with synthetic speech output

The hardware configuration and software for a voice-output communications station are described. Advantages of such a capability in computer-aided instruction and as an aid for the visually handicapped are noted. The man-computer communication station incorporates a relatively inexpensive digitally controlled voice synthesizer.     

Posttraumatic stress disorder symptoms, psychological distress, personal resources, and quality of life in four groups of Holocaust child survivors

The objective of the present study was to inquire into the long-term effects of child survivors' Holocaust experience. To this end, 170 Holocaust survivors who were born after 1926 completed questionnaires with regard to psychological distress, Posttraumatic Stress Disorder (PTSD), Quality of Life (QoL), Self-identity, and Potency. The survivors were divided into four groups based on the setting of their experience during the Holocaust: Catholic Institutions, Christian foster families, concentration camps, and hiding in the woods and/or with partisans. Results showed that survivors who had been with foster families scored significantly higher on several of the measures of distress, whereas survivors who had been in the woods and/or with partisans scored significantly higher on several of the positive measures, QoL, potency, and self-identity. The discussion focuses on understanding the different experiences according to developmental theory and sense of control. It was concluded that there are group differences between child survivors according to their Holocaust experience.     

Using behavior contracts to improve behavior of children and adolescents in multiple settings

Research has shown that behavior contracts, a form of contingency management, can promote a wide range of behavior changes for individuals in varied populations; however, relatively few studies have been conducted in nonacademic settings. In the context of two service projects, we evaluated the extent to which behavior contracts improved problem behavior for 11 children and adolescents in residential treatment facilities and foster homes using nonconcurrent multiple baseline across participants’ designs with three or more tiers and supplemental statistical analysis for each tier. Practitioners in each setting implemented individualized behavior contracts for 5 to 59 weeks. Results show that behavior improved substantially for six participants but was relatively unchanged for the other five participants. We discuss the limitations of this clinically driven study, as well as clinical implications of our mixed findings.     

Alignment with globalized Western culture: Between inclusionary values and an exclusionary social identity

Reactions to globalized Western culture (GWC) are influential in shaping intergroup relations and social issues worldwide. GWC is conceptualized here as an inclusionary cultural value system but a simultaneously exclusionary social identity. Whereas GWC's inclusive values may promote the civil liberties and fair treatment of gay people, for instance, as a social identity, groups may use their alignment with GWC to buttress ingroup superiority over less aligned outgroups. Three studies (one correlational and two experimental in design) probe these opposing vectors in samples of Jewish‐Israelis, who are generally highly aligned with GWC. Results demonstrate that GWC alignment is associated with decreased anti‐gay prejudice (Studies 2 and 3) but exclusionary responses towards Arab individuals and groups (Studies 1, 2, and 3), who are perceived to be less aligned with GWC. Conducted during the 2014 Israeli‐Palestinian war, Study 3 notably demonstrated that a GWC identification prime reduced Jewish‐Israelis' willingness to offer humanitarian assistance to Palestinian civilians in need. This may suggest that in some contexts, GWC's divisive function as a social identity supersedes its more inclusionary humanistic values. These contrary effects of GWC alignment by social target are discussed, alongside their implications on national, regional, and international levels.     

A multi-session interpretation modification program: changes in interpretation and social anxiety symptoms

Previous research suggests that socially anxious individuals interpret ambiguous social information in a more threatening manner compared to non-anxious individuals. Recently, studies have experimentally modified interpretation and shown that this subsequently affected anxiety in non-anxious individuals. If similar procedures can modify interpretation biases in socially anxious individuals, they may lead to a reduction in social anxiety symptoms. In the current study, we examined the effect of a computerized Interpretation Modification Program (IMP) on interpretation bias and social anxiety symptoms. Twenty-seven socially anxious individuals were randomly assigned to the IMP or a control condition. Participants completed eight computer sessions over four weeks. The IMP modified interpretation by providing positive feedback when participants made benign interpretations and negative feedback in response to threat interpretations. The IMP successfully decreased threat interpretations, increased benign interpretations, and decreased social anxiety symptoms compared to the control condition. Moreover, changes in benign interpretation mediated IMP's effect on social anxiety. This initial trial suggests that interpretation modification may have clinical utility when applied as a multi-session intervention.     

Revising the concept of lawhood: special sciences and natural kinds

The Kripkean conception of natural kinds (kinds are defined by essences that are intrinsic to their members and that lie at the microphysical level) indirectly finds support in a certain conception of a law of nature, according to which generalizations must have unlimited scope and be exceptionless to count as laws of nature. On my view, the kinds that constitute the subject matter of special sciences such as biology may very well turn out to be natural despite the fact that their essences fail to be microphysical or micro-based. On the causal conception of natural kinds I privilege, the naturalness of a kind is a function of the fact that it figures prominently in at least one causal law. However, there is a strong tendency prevailing among contemporary philosophers to assume that, in order to count as proper laws generalizations must be expectionless. Since most generalizations tracked down by the special sciences turn out not to fulfill these criteria, what this conception of a law implies is that most of the generalizations the special sciences trade in are not proper laws. It follows that, on this view, most if not all of the kinds the special sciences dealing with turn out not to constitute natural kinds, understood as kinds to which bona fide laws apply. In order to establish that the non-microstructurally defined kinds that fall within the domain of enquiry of the special sciences are eligible for the status of natural kind, I must therefore establish that generalizations needn’t have unlimited scope and be exceptionless to count as laws of nature. This is precisely what I seek to do in this paper. I begin by arguing that the question “what is a law of nature?” is most naturally interpreted as the question “what features must generalizations exhibit in order to ground scientific explanations?” and by offering reasons to believe that generalizations needn’t be exceptionless and have unlimited scope to play the crucial role laws have been thought to play in scientific explanation. Drawing on Sandra Mitchell [Mitchell, S. (2000). Philosophy of Science, 67, 242–265] and James Woodward’s [Woodward, J. (1997). Philosophy of science, 64 (proceedings), 524–541; Woodward, J. (2000). British Journal for the philosophy of science, 51(2), 197–254; Woodward, J. (2001). Philosophy of science, 68, 1–20] work, I subsequently develop an alternative account of the criteria generalizations must satisfy in order to count as laws of nature, which at least some of the generalizations of the special sciences turn out to fulfill. I thus give credence to the idea that at least some of the kinds that fall within the domain of the special sciences figure in laws of nature, and I thereby restore the possibility that some special science kinds deserve to be deemed natural.     

Overlooked but not untouched: How rudeness reduces onlookers’ performance on routine and creative tasks

In three experimental studies, we found that witnessing rudeness enacted by an authority figure (Studies 1 and 3) and a peer (Study 2) reduced observers’ performance on routine tasks as well as creative tasks. In all three studies we also found that witnessing rudeness decreased citizenship behaviors and increased dysfunctional ideation. Negative affect mediated the relationships between witnessing rudeness and performance. The results of Study 3 show that competition with the victim over scarce resources moderated the relationship between observing rudeness and performance. Witnesses that were in a competition with the victim felt less negative affect in observing his mistreatment and their performance decreased to a lesser extent than observers of rudeness enacted against a non-competitive victim. Theoretical and practical implications are discussed.
