Effects of alcohol and frustration on experimental graffiti

This study aimed to examine effects between alcohol and frustration in regard to graffiti. Forty-two subjects, 21 men and 21 women were randomly assigned in equal numbers to each of the three experimental groups, namely a Control group, an Alcohol group, and an Alcohol+Frustration group (alcohol dose: 1 ml 100% alcohol/kg body weight). For the purposes of this experiment, a test (AET) was constructed that provided scores of "scrawling-graffiti" (i.e., the amount of scrawling on pictures), "destruction", "aggression", and "sexuality". An elaboration test and a test measuring the "dispositional optimism" were also applied. The primary results indicated that (a) the Alcohol+Frustration group scored significantly higher on scrawling-graffiti compared to the Control group, (b) female subjects performed graffiti-scrawling to a greater extent than male subjects in all three groups, (c) women scored significantly higher on elaboration as compared to men. These results were interpreted as supporting the hypothesis that alcohol intake by itself is unlikely to induce destructive behavior unless accompanied by a "provocative" factor (e.g. frustration) that precipitates the putative expressions of aggressiveness.     

Errors of the standard in the horizontal-vertical illusion

Three experiments were conducted to test the claim that the magnitude of the horizontal-vertical illusion in an L figure varies as a function of which component is used as standard. No difference was found in Experiment 1, in which a staircase procedure was used to establish the PSE. However, by the use of a method of adjustment, the magnitude of illusion was affected by the component used as standard in Experiment 2. The results of Experiment 3, in which a staircase procedure was used with S in upright and recumbent body postures, confirmed those of Experiment 1. It was concluded that earlier differences associated with the standard were a methodological accompaniment of the psychophysical technique used.     

A comparative view of the new journal: Assessment

The reference sections from all articles in the 1997 volumes of Assessment, Journal of Personality Assessment, and Psychological Assessment were entered into a database and analyzed. An article published in Assessment averaged almost 31 references. An article published in Journal of Personality Assessment contained an average of 33 references. Psychological Assessment averaged 38 references per article. The median age of the references in the three journals was 8 years with an interquartile range of 4 to 14 years. The Journal of Personality Assessment had the largest number of citations in this database of 5,316 references. Each of these received a relatively large number of their citations from articles published in the same journal (self-citations). Randomly selected articles from the 1997 volume of Assessment received fewer citations in the Social Science Citation Index than a similar set of articles from the other two journals. However, the data on Assessment, when compared with data available on other new scientific publications, suggests that Assessment is doing as well as other fledgling journals.     

Incremental validity of the Minnesota Multiphasic Personality Inventory-2 and symptom checklist-90-revised with mental health inpatients

This study evaluated the incremental validity of scores from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the Symptom Checklist-90-Revised (SCL-90-R) in a sample of mental health inpatients originally published by Archer, Griffin, and Aiduk (1995). The incremental validity of scores from the SCL-90-R primary symptom dimensions and MMPI-2 Clinical, Content, and Restructured Clinical scales was assessed in a sample of 544 mental health inpatients using conceptually related items from the Brief Psychiatric Rating Scale (BPRS) as criteria. A series of hierarchical multiple regressions indicated that scores from the SCL-90-R primary symptom dimensions exhibited limited incremental validity (Mdn DeltaR(2) = .01, range = 0-.01), whereas scores from MMPI-2 scales contributed additional information in the prediction of ratings on all but one BPRS item (Mdn DeltaR( 2) = .08, range = .04-.12).     

Face viewpoint effects about three axes: the role of configural and featural processing

We directly compared recognition for faces following 0 degrees-75 degrees viewpoint rotation about the yaw, pitch, and roll axes. The aim was to determine the extent to which configural and featural information supported face recognition following rotations about each of these axes. Experiment 1 showed that performance on a sequential-matching task was viewpoint-dependent for all three types of rotation. The best face-recognition accuracy and shortest reaction time was found for roll rotations, then for yaw rotations, and finally the worst accuracy and slowest reaction time was found for pitch rotations. Directional differences in recognition were found for pitch rotations, but not for roll or yaw. Experiment 2 provided evidence that, in all three cases, viewpoint-dependent declines in recognition were primarily driven by the loss of configural information. However, it also appeared that significant featural information was lost following yaw and pitch (but not roll) rotations. Together, these findings show that unfamiliar-face recognition is viewpoint-dependent following rotation about each axis (and in each direction), and that performance is based on the availability of configural and, to a lesser extent, featural information.     

Is Relational Demography Relative? How Employment Status Influences Effects of Supervisor–Subordinate Demographic Similarity

Purpose  

Because diversity is vital to many businesses, it is important to understand how demographic differences between individuals in the workplace influence employee behavior. In this study, we focused on demographic similarity (i.e., sex, racioethnicity) with one’s supervisor as a predictor of employee withdrawal. Further, we examined employees’ employment status (i.e., part-time vs. full-time) as a moderator of the similarity–withdrawal relationships.     

Evaluation of an Internet-short message service-based intervention for promoting physical activity in Hong Kong Chinese adolescent school children: a pilot study

Evaluation of acceptability and preliminary efficacy of an Internet and short message service (SMS) intervention for promoting physical activity (PA) in Hong Kong Chinese school children. An 8-week quasi-experimental study non-randomly assigned 78 school children (mean age=12.8 years) to (a) an intervention group that received a stage-matched, Internet PA program two times a week and tailored SMS messages daily; or (b) a no-treatment control. Data were collected from September 2008 until June 2009. Acceptability measures included exposure rate and participant's satisfaction. Efficacy measures were changes in stage of motivational readiness (SMR) and self-reported PA level. Intervention participants demonstrated significant pre-post increments in SMR (Z=-2.558, p=0.011) and self-reported PA level [F(1, 76)=4.50, p=0.04]. There was a non-significant trend between groups in both SMR (p=0.24) and PA (p=0.13). Despite the similar ratings of satisfaction between Internet (M=3.12±0.74) and SMS (M=3.12±0.84), participants displayed distinct patterns of exposure with 66% exhibiting a weekly login rate of 0.5 times/person and an average of 3.75 minutes/visit/person. In contrast, 79% of participants read an average of 1.3 SMS/person/week and 47% voluntarily replied to ～3.8 SMS/person. These findings demonstrate the acceptability and preliminary efficacy of an Internet-SMS-based intervention for promoting PA in Hong Kong school children. The divergent exposure rates between the Internet and SMS may be a unique pattern for adolescents in early SMR. Future research should be cognizant of the importance of SMR since it may influence utilization and/or adherence.     

Conflict management: A premarital training program in mutual problem solving

Abstract

The purpose of this study was to evaluate the effectiveness of a structured educational program designed to train premarital couples in communication and mutual problem-solving skills. Twenty-six couples participated in an eight-week, 24-hour problem-solving training program, while 28 similar couples participated in an eight-week, 24-hour relationship discussion group. Results indicated that the problem-solving group, as compared to the relationship-discussion group, showed a significant increase in communication and mutual problem-solving skills. Discussion focused on the benefits for premarital couples of learning effective problemsolving procedures as well as the need for follow-up assessments of both behavioral skill level and relationship satisfaction and adjustment.
