Evolution, Traits, and the Stages of Human Courtship: Qualifying the Parental Investment Model

ABSTRACT Individual differences are explicitly connected to social interaction in Darwin's notion of sexual selection Traits that increase the probability of successful reproduction will tend to increase in frequency This process operates partly through differential choice, by one sex, of certain traits in the other According to the parental investment model, females frequently have more stringent criteria for the traits they will accept in a mate because they have a relatively larger investment in each offspring Because human mating arrangements often involve a substantial commitment of resources by the male, it is necessary to invoke a distinction between the selectivity involved during casual mating opportunities and the selectivity exercised when choosing a long-term partner Ninety-three undergraduate men and women rated their minimum criteria on 24 partner characteristics at four levels of commitment In line with an unqualified parental investment model, females were more selective overall, particularly on status-linked variables In line with a qualified parental investment model, males' trait preferences depended upon the anticipated investment in the relationship Males had lower requirements for a sexual partner than did females, but were nearly as selective as females when considenng requirements for a long-term partner     

Is the implicit association test immune to faking?

One of the main advantages of measures of automatic cognition is supposed to be that they are less susceptible to faking than explicit tests. It is an empirical question, however, to what degree these measures can be faked, and the response might well differ for different measures. We tested whether the Implicit Association Test (IAT, Greenwald, McGhee, & Schwartz, 1998) cannot be faked as easily as explicit measures of the same constructs. We chose the Big-Five dimensions conscientiousness and extraversion as the constructs of interest. The results show, indeed, that the IAT is much less susceptible to faking than questionnaire measures are, even if no selective faking of single dimensions of the questionnaire occurred. However, given limited experience, scores on the IAT, too, are susceptible to faking.     

Lebanese adolescents’ expectations about social inclusion of peers in intergroup contexts

This study examined the role of group norms, group identity, age, contact, and stereotypes on youths’ decisions to include a peer in an intergroup context portraying Lebanese and American adolescents. Lebanese participants (N = 275), ages 12 and 16 years, were surveyed about expectations for inclusion of an out-group target with similar interests or an in-group target with different interests into their own Lebanese group or another American group. Findings indicated participants focused on shared interests, rather than national identity, when making inclusion decisions for either group and group norms mattered. Older participants expected American peers to be less inclusive towards an out-group peer. Direct contact predicted inclusivity of out-group American peers into one’s own Lebanese group, and indirect media-based contact predicted expectations for inclusivity into an American out-group. Findings have implications for interventions aimed at improving cross-national friendships which, in turn, have the potential to reduce prejudicial attitudes.     

Psychometrics properties of the Swansea Muscularity Attitudes Questionnaire (SMAQ)

The psychometric soundness of the Swansea Muscularity Attitudes Questionnaire (SMAQ) was examined using two independent samples of Canadian male post-secondary students (Ns = 250 and 310, respectively). Exploratory and confirmatory factor analyses suggested that the final 19-item version of the SMAQ is represented by three latent constructs, which we have labeled: intention to become more muscular (eight-items), positive attributes of muscularity (nine-items), and engagement in muscle-building activities (two-items). Alpha coefficients for the intention and positive subscales were very good (i.e., range = .86–.92). Correlation coefficients between the two-items comprising the engagement subscale also suggest that they can be combined into a composite measure (rs = .70 [study 1] and .58 [study 2]). Various tests of criterion-related and construct validity were conducted, with results indicating that the SMAQ subscales are valid indicants of the drive for muscularity.     

Cognitive therapy for post-traumatic stress disorder: development and evaluation

The paper describes the development of a cognitive therapy (CT) program for post-traumatic stress disorder (PTSD) that is based on a recent cognitive model (Behav. Res. Therapy 38 (2000) 319). In a consecutive case series, 20 PTSD patients treated with CT showed highly significant improvement in symptoms of PTSD, depression and anxiety. A subsequent randomized controlled trial compared CT (N = 14) and a 3-month waitlist condition (WL, N = 14). CT led to large reductions in PTSD symptoms, disability, depression and anxiety, whereas the waitlist group did not improve. In both studies, treatment gains were well maintained at 6-month follow-up. CT was highly acceptable, with an overall dropout rate of only 3%. The intent-to-treat effect sizes for the degree of change in PTSD symptoms from pre to post-treatment were 2.70-2.82 (self-report), and 2.07 (assessor-rated). The controlled effect sizes for CT versus WL post-treatment scores were 2.25 (self-report) and 2.18 (assessor-rated). As predicted by the cognitive model, good treatment outcome was related to greater changes in dysfunctional post-traumatic cognitions. Patient characteristics such as comorbidity, type of trauma, history of previous trauma, or time since the traumatic event did not predict treatment response, however, low educational attainment and low socioeconomic status were related to better outcome.     

Influence of participation in a cup-stacking unit on timing tasks

Cup stacking is a relatively new activity which has been promoted at conferences for physical educators as having many direct and indirect benefits, such as improved quickness. This study examined the influence of a cup-stacking instructional unit on reaction and anticipation times of 69 children in Grades 2 and 4. Within each grade participants were assigned to an experimental or a control group. The former received a 3-wk. instructional unit following the lesson plans provided by the promoters of cup stacking. The control groups received a standard physical education curriculum. Analysis indicated no significant differences in reaction and anticipation times between the groups before and after practicing the instructional unit.     

Perfectionism,social problem-solving ability,and psychological distress

The present research examined the relation between dimensions of perfectionism and self-appraised problem-solving behaviors and attitudes. Specifically, in two separate studies, we tested the hypothesis that socially prescribed perfectionism (i.e., the perception that others demand perfection from the self) is associated with poorer social problem-solving ability. In addition, measures of psychological adjustment were included in Study 2 so that we could (1) examine whether socially prescribed perfectionism and poorer problem-solving ability were still associated after removing variance associated with psychological distress; and (2) compare depression and anxiety in terms of their respective associations with social problem-solving ability. Correlational analyses of the data from both studies confirmed that socially prescribed perfectionism is associated with more negative self-perceptions of problem-solving orientation, and that the link between socially prescribed perfectionism and negative perceptions of problem-solving orientation remains present after removing variance due to levels of negative affectivity. Both depression and anxiety were associated with a negative problem-solving orientation, but only depression was associated with more negative appraisals of actual problem-solving skills. The results suggest that perceived exposure to imposed standards of perfection undermines the problem-solving process and that individuals with high levels of socially prescribed perfectionism are particularly in need of counseling interventions designed to provide a more positive problem-solving orientation.This research was supported by grants #410-91-0856 and #410-93-1256 from the Social Sciences and Humanities Research Council of Canada. An earlier version of this paper was presented at the 1994 annual meeting of the Eastern Psychological Association in Providence, Rhode Island.

Genetic Counselors’ Religiosity & Spirituality: Are Genetic Counselors Different from the General Population?

Although there is evidence that the religious beliefs of genetic counselors (GCs) can induce internal conflict in at least some genetic counseling scenarios, empirical research on the religiosity of GCs is limited. This study compares genetic counselors to a representative sample of the adult U.S. population on multiple religiosity measures. After controlling for several sociodemographic factors the percentage of GCs who report having a religious affiliation is similar to the general U.S., but GCs are less likely to affiliate with conservative Christian religions and are more likely to be Jewish. GCs are significantly less likely than the general U.S. population to: believe in god, attend religious services, pray, and believe in an afterlife even after controlling for relevant sociodemographic factors. Despite the lower levels of religiosity, a majority of GCs do report themselves to be moderately to highly spiritual. We explore potential reasons for religiosity differences as well as possible implications in the context of the GC scope of practice.     

Hostile Intent Attributions and Relational Aggression: The Moderating Roles of Emotional Sensitivity,Gender, and Victimization

The current study adopts a relational vulnerability model to examine the association between hostile attribution bias and relational aggression. Specifically, the relational vulnerability model implicates the interactive effects of a number of relational risk factors in the development of relational aggression. A sample of 635 3rd, 4th, and 5th grade students (50.2% females) completed a self-report measure assessing hostile attribution bias and emotional distress for relational provocations. Peer nominations and teacher reports of relational aggression and relational victimization were also collected. Results supported the relational vulnerability model for girls only. Specifically, hostile attribution bias was associated with relational aggression only when relational victimization and emotional distress were also high. Implications for future research and clinical practice are discussed.
