Alcohol-Involved Rapes: Are They More Violent?

Alcohol's psychological, cognitive, and motor effects contribute to rape. Based on theory and past research, we hypothesized that there would be a curvilinear relationship between the quantity of alcohol consumed by perpetrators and how aggressively they behaved. Moderate levels of intoxication encourage aggressiveness; however, extreme levels severely inhibit cognitive and motor capacity. We also hypothesized that victims' alcohol consumption would have a curvilinear relationship to their resistance. These hypotheses were examined with data from 132 college women who had been the victims of attempted or completed rape. Although there was a curvilinear result for perpetrators, the slope of the curve suggested that aggressiveness was worst when no alcohol or the highest levels of alcohol were consumed. There was a negative linear relationship between victims' alcohol consumption and resistance. Difficulties associated with accurately assessing degree of intoxication from survey data are discussed and suggestions are made for improving alcohol measurement in rape research.     

Accounting for the shared environment in cognitive abilities and academic achievement with measured socioecological contexts

Behavioral and molecular genetic research has established that child cognitive ability and academic performance are substantially heritable, but genetic variation does not account for all of the stratification of cognitive and academic outcomes across families. Which specific contexts and experiences contribute to these shared environmental influences on cognitive ability and academic achievement? Using an ethnically and socioeconomically diverse sample of N = 1728 twins ages 7–20 from the Texas Twin Project, we identified specific measured family, school, and neighborhood socioecological contexts that statistically accounted for latent shared environmental variance in cognitive abilities and academic skills. Composite measures of parent socioeconomic status (SES), school demographic composition, and neighborhood SES accounted for moderate proportions of variation in IQ and achievement. Total variance explained by the multilevel contexts ranged from 15% to 22%. The influence of family SES on IQ and achievement overlapped substantially with the influence of school and neighborhood predictors. Together with race, the measured socioecological contexts explained 100% of shared environmental influences on IQ and approximately 79% of shared environmental influences on both verbal comprehension and reading ability. In contrast, nontrivial proportions of shared environmental variation in math performance were left unexplained. We highlight the potential utility of constructing “polyenvironmental risk scores” in an effort to better predict developmental outcomes and to quantify children's and adolescents’ interrelated networks of experiences.

Gender, Internet identification, and Internet anxiety: correlates of Internet use.

This paper reports a study that investigated the effects of gender, Internet anxiety, and Internet identification on use of the Internet. The study involved 608 undergraduate students (490 females and 118 males). We surveyed the students' experience with the Internet, as well as their levels of Internet anxiety and Internet identification. We found a number of gender differences in participants' use of the Internet. Males were proportionally more likely to have their own web page than were females. They used the Internet more than females; in particular, they were more likely to use game websites, to use other specialist websites, and to download material from the Internet. However, females did not use the Internet for communication more than males. There was a significant positive relationship between Internet identification and total use of the Internet, and a significant negative relationship between Internet anxiety and total use of the Internet. Controlling for Internet identification and Internet anxiety, we found a significant and negative correlation between gender and use of the Internet. In total, all three of our predictors accounted for 40% of the variance in general Internet use: with Internet identification accounting for 26%, Internet anxiety accounting for 11%, and gender accounting for 3%.     

The cross‐cultural generalizability of personality types: a Philippine study

Research on personality types was extended to a non‐Western culture, the Philippines. In two large samples of Filipino college students, cluster analyses of self‐rated trait adjectives revealed interpretable three‐cluster solutions (i.e. types) for each gender. The types differed on indigenous measures of ego resiliency and ego control and exhibited sensible configurations of Big Five traits, indigenous Filipino traits, and behavioural indicators. Most types were interpretable in terms of the concepts of ego resiliency and ego control of Block and Block ( 1980 ) and resembled types identified in other cultures. Two of three male and female types were fairly comparable and some types replicated across data sets. The results provided some support for the cross‐cultural comparability of personality types and for typological research in general. Copyright © 2005 John Wiley & Sons, Ltd.     

Reliability and validity of the Yale Global Tic Severity Scale

To investigate the reliability and validity of the Yale Global Tic Severity Scale (YGTSS), 28 youth aged 6 to 17 years with Tourette's syndrome (TS) participated in the study. Data included clinician reports of tics and obsessive-compulsive disorder (OCD) severity, parent reports of tics, internalizing and externalizing problems, and child reports of depression and anxiety. All children participated in a 2nd YGTSS administration by the same rater 48 days later. Good internal consistency and stability were found for the YGTSS scores. YGTSS scores demonstrated strong correlations with parent-rated tic severity (r = .58-.68). YGTSS scores were not significantly related to measures of clinician ratings of OCD severity (r = .01-.15), parent ratings of externalizing and internalizing behavior (r = -.07-.20), and child ratings of depression (r = .02-.26) and anxiety (r = -.06 -.28). Findings suggest that the YGTSS is a reliable and valid instrument for the assessment of pediatric TS.     

Temporal learning in random control procedures

Experiments 1 and 2 delivered conditioned stimuli (CSs) at random times and unconditioned stimuli (USs) at either fixed (Experiment 1) or random (Experiment 2) intervals. In Experiment 3, CS duration was manipulated, and US deliveries occurred at random during the background. In all 3 experiments, the mean rate of responding (head entries into the food cup) in the background was determined by the mean US-US interval, and the mean rate during the CS was a linear combination of responding controlled by the mean US-US and mean CS onset-US intervals; the pattern of responding in time was determined by the interval distribution form (fixed or random). An event-based timing account, Packet theory, provided an explanation of the results.     

Stammering and therapy views of people who stammer

This study used a postal questionnaire to seek the views of adults who stammer concerning the effect of stammering on their lives, the speech and language therapy and other remedies they have tried, and their hopes for speech and language therapy in the future. The 332 returned questionnaires indicated that stammering had the greatest adverse effect on school life and occupation. Speech and language therapy had been helpful to many, but the nature of the benefits and specific therapies used were not cited in many responses. An emergent theme in unhelpful therapy was the dissatisfaction that arises when individual needs are not met. In the future, people want help in controlling stammering and in developing coping strategies. The desire for timely and effective therapy for children, ongoing help and for group or intensive work has implications for service organization and therapist's skills. The survey highlights the need for therapists and clients to negotiate therapy aims and procedures that are clearly defined, appropriate to individual needs, achievable, and, if possible, recorded and measured. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to list (1) the areas most and least affected by stammering, (2) the therapy approaches respondents had found helpful, and (3) other remedies that tried to help stammering.     

Measuring individual and cultural differences in implicit trait theories

A new measure of implicit theories or beliefs regarding the traitedness versus contextuality of behavior was developed and tested across cultures. In Studies 1 (N = 266) and 2 (N = 266), these implicit beliefs dimensions were reliably measured and replicated across U.S. college student samples and validity evidence was provided. In Study 3, their structure replicated well across an individualistic culture (the United States; N = 249) and a collectivistic culture (Mexico; N = 268). Implicit trait and contextual beliefs overlapped only modestly with implicit entity theory beliefs and were predicted by self-construals in ways that generally supported cultural psychology hypotheses. Implicit trait beliefs were fairly strongly endorsed in both cultures, suggesting that such beliefs may be universally held.     

Stimulus and temporal cues in classical conditioning

In 2 experiments, separate groups of rats were given stimulus conditioning, temporal conditioning, untreated control and (in Experiment 2) learned irrelevance control procedures, followed by a compound with both stimulus and temporal cues. Stimulus conditioning consisted of a random 15-s duration conditioned stimulus (CS) followed by food; temporal conditioning consisted of food-food intervals of fixed 90 s (Experiment 1) or fixed 75 + random 15 s (Experiment 2). The stimulus group abruptly increased responding after CS onset, and the temporal group gradually increased responding over the food-food interval. When the food-food interval was fixed 90 s, the temporal cue exerted stronger control in the compound, whereas when the food-food interval was fixed 75 + random 15 s, the stimulus cue exerted stronger control. The strength of conditioning, temporal gradients of responding, and cue competition effects appear to reflect simultaneous timing of multiple intervals.     

The Impact of Leadership Style on Global Management Practices1

A study was conducted to explore the impact of differences in leadership style on the practice of global leadership and management. Data were collected from 391 senior managers from a global organization and 1,701 of their direct reports, 358 straight-line supervisors, and 266 dotted-line supervisors. ANOVA results indicate that transformational leaders were rated significantly higher on all behaviors by their direct reports than were transactional leaders. Straight-line supervisors rated transformational leaders significantly higher on managing change- and relationship-management behaviors, whereas dotted-line supervisors rated transformational leaders higher on learning orientation. Finally, transformational leaders were significantly more self-aware (greater congruence in self vs. direct reports' average ratings) regarding the practice of these behaviors. implications for future research are discussed.
