Emotional correlates of the different dimensions of schizotypal personality disorder

Two studies explored which different dimensions of schizotypal personality disorder (SPD) were associated with negative affect, attention to emotions, clarity of emotions, and emotional intensity/instability. Study 1 included 247 college students, and questionnaires were used to measure SPD. Study 2 included 225 community residents, oversampling for individuals with elevated levels of SPD, and semistructured diagnostic interviews were used to measure SPD. In both studies (a) higher levels of negative affect were associated with higher levels of both cognitive-perceptual and interpersonal symptoms, (b) cognitive-perceptual disturbances were associated with greater attention to emotion, whereas interpersonal disturbances were associated with less attention to emotion, and (c) lower levels of emotional clarity were associated with higher levels of suspiciousness.     

The crossed-hands deficit in tactile temporal-order judgments: the effect of training

Several recent studies have shown that judgments of temporal order for tactile stimuli presented to the two hands are greatly affected by crossing the hands. The size of the threshold for judging temporal order may be up to four times larger with the hands crossed as compared to the hands uncrossed. The results from these recent studies suggest that with crossed hands, contrary to many situations involving the integration of tactile and proprioceptive information, subjects have difficulty in adjusting their perception of tactile inputs to correspond with the spatial positions of the hands. In the present study we examined the effect of training in judging temporal order on the size of this crossed-hands deficit--the difference in the thresholds for temporal-order judgments when the hands are crossed and uncrossed. All training procedures produced significant declines in the size of the deficit. With training, the difference between crossed-hands and uncrossed-hands temporal-order thresholds dropped from several hundred milliseconds to as little as 19 ms. A group of percussionists with experience in playing with crossed hands showed the same crossed-hands effects as non-musicians. The results were consistent in showing that the crossed-hands deficit was never completely eliminated but was greatly reduced with training. The implication is that subjects are able to adjust to the crossed-hands posture with modest amounts of training. The results are discussed in terms of the explanations that have been offered for the crossed-hands deficit.     

A review of research on the effects of religion on adolescent tobacco use published between 1990 and 2003

An electronic search of Medline and PsycInfo produced 29 studies that specifically investigated the effects of religion on adolescent tobacco use. Independent (religion) and dependent (tobacco use) variables and variables controlled for in statistical analyses were categorized. Twenty-two of the 29 studies reported at least one significant effect of religion on tobacco use, with 31 of 43 separate analyses of religious variables yielding significant negative correlations between religion and tobacco use. Religion was inversely related to all measures of tobacco use (lifetime, occasional, and regular use), but the findings suggest religion's primary effect is its prohibitive influence against ever using tobacco.     

The effect of test schedules on the formation of linked perceptual classes

After training conditional discriminations among selected stimuli from two perceptual classes, the emergence of novel relations involving other members of both classes was assessed using cross-class probes. The cross-class probes were presented using one of four different testing schedules. In the 2/9 test, nine different probes were presented in each of two test blocks. In the 6/3 test, three different probes were presented in each of six test blocks. In the 18/1-RND test, each of the 18 cross-class probes was presented in separate test blocks. In the 2/9 and 6/3 tests, the cross-class probes were presented in a randomized order within test block. In the 18/1-RND test, the cross-class probes were presented in a randomized sequence. In the 18/1-PRGM test, however, the cross-class probes were presented in a programmed order (i.e., the values of the stimuli in each cross-class probe were changed systematically in the succession of probe presentations). About 55% of the linked perceptual classes emerged during the 2/9, 6/3, and 18/1-RND tests. Thus the number of different probes in a test block did not influence the emergence of classes as long as the probes were presented in a random order. Virtually all classes emerged during the 18/1-PRGM test. Thus at least one ordered introduction of different cross probes resulted in the reliable emergence of linked perceptual classes. Mechanisms responsible for linked perceptual class formation are discussed along with the relation of these classes to other complex categories.     

Three Questions Regarding the Ecological Validity of Experimental Research on the Impact of Viewing Thin-Ideal Media Images

We experimentally examined fairness perceptions of accommodating people with disabilities by manipulating the granting of an accommodation, reward structure, and the best performer on a word search task. Data from 134 undergraduate students indicated that granting an accommodation was seen as less fair than not granting it, that having a person with a disability excel in performance was seen as less fair than when the person did not excel, and that fairness perceptions were lowest when the person with a disability received an accommodation and excelled in performance. Although the intent of the Americans with Disabilities Act (ADA) is to level the playing field for people with disabilities, our results show that when an accommodation helps the requester, others think it is unfair.     

Studies in the Principles of Judgments and Attitudes: I. Two Basic Principles of Judgment

The psychological test performance of 10 seven-year-old boys from an isolated, rural Guatemalan village was compared with ratings of their intelligence made by 42 adult village members. The adults' judgments were found to correlate strongly with the children's performance on the Embedded Figures, Verbal Analogies, and Memory-for-Designs Tests.     

Neurobehavioral Functioning in Children with Fetal Alcohol Spectrum Disorder

Neurobehavioral functioning of 50 Canadian children diagnosed with Fetal Alcohol Spectrum Disorder (FASD) was evaluated. The aims of this study were to identify specific areas of weakness in neurobehavioral functioning, to examine whether neurobehavioral functioning was related to various predictor variables, and to determine which measures differentiated between children given a brain score of 2 (possible dysfunction) and 3 (probable dysfunction). Participants displayed difficulties with many aspects of intelligence, memory, executive functioning, and attention. Measures of Full scale and Verbal IQ, as well as memory for faces and numbers differentiated between children with a brain 2 and 3 ranking. An interesting pattern of strengths and weaknesses emerged as well as significant differences related to ethnic background, gender, and age. Aboriginal children and Caucasian children with FASD do not appear to show the same pattern of strengths and weaknesses in neurobehavioral functioning.     

American Military Veteran Entrepreneurs: A Comprehensive Profile of Demographic,Service History,and Psychosocial Characteristics

American military veterans are nearly twice as likely to be self-employed compared with nonveterans and are majority owners in 9% of all businesses nationwide. Despite their contribution to the broader economy and the potential for training programs to cultivate and foster successful self-employment and veteran-lead entrepreneurial ventures, research on veteran entrepreneurs remains limited. To gain a better understanding of the potential strengths and vulnerabilities of veteran entrepreneurs, the current study utilized data from a large, nationally representative sample to profile self-employed veterans (n = 230) and compare them with veterans who work as employees (n = 1,055) with respect to demographic, military service history, and psychosocial characteristics. Results indicated that self-employed veterans were older and more educated and more likely to utilize U.S. Department of Veteran’s Affairs (VA) health care. Self-employed veterans were more likely to serve in Vietnam and to serve in the military for fewer years. No differences were noted in perceived military experience, level of combat exposure, or military branch served as a function of self-employment. Although reporting more lifetime traumas, self-employed veterans did not experience higher rates of current or lifetime psychopathology or lower perceived quality of life. Potential protective resilience-promoting factors may be associated with the higher levels of openness, extraversion, optimism, achievement-orientation (purpose in life), and greater need for autonomy and professional development observed among self-employed veterans. Moreover, self-employed veterans demonstrated higher levels of gratitude, community integration, and altruistic service to others. Findings have potential to inform human resources management strategies and vocational training and reintegration initiatives for veterans.
