Group therapy for eating disorders: A step-wise approach

Group therapy is emerging as a favored treatment for eating disorders. Open-ended psychodynamic group therapy is an effective treatment for the underlying conflicts in eating-disordered patients, yet these groups are difficult to form. The authors suggest a specific sequence using time-limited psychoeducational groups initially for symptom control, then offering an open-ended group for patients who are ready to address deeper issues in a group therapy setting.     

Prioritizing Patients for Surgery: Factors Affecting Allocation of Medical Resources for Kidney Transplantation,IVF, and Rhinoplasty1

The present study sought to investigate whether the factors that affect the allocation of scarce medical resources vary across different types of treatment and whether participants prioritize hypothetical patients based on patients' marital status, annual income, history of mental illness, and smoking habits. Study participants (N = 114) made prioritization decisions that were found to be very different across treatments. Repeated‐measure ANOVAs showed that single patients were favored for rhinoplasty, while married patients were favored for in vitro fertilization (IVF) and kidney transplant treatment. Nonsmoking patients were preferred over their smoking counterparts. Low‐income patients were favored for rhinoplasty and kidney transplant operations, but not for IVF. Mentally healthy patients were generally preferred over mentally ill patients.

本文主要介绍各种肝血流阻断的方法及各种方法的选择策略。持续性肝门阻断是较古老和简单的肝血流控制方法,目前仍被外科医生广泛的应用。间歇性肝门阻断、半肝血流阻断和保留腔静脉通畅的全肝血流阻断主要适用于肝实质异常的患者,全肝血流阻断操作复杂,并且有10％～20％的患者不能耐受阻断期间血液动力学变化,但是对于需要进行广泛下腔静脉重建的肝脏手术非常适合,保留腔静脉通畅的全肝血流阻断方法适用于涉及肝静脉重建或局限性下腔静脉重建的手术。肝脏手术中肝血流阻断方法的选择,应根据病变位置、肝脏病理变化程度、患者心血管情况以及术者和麻醉医师的经验和习惯等情况综合考虑而定。     

Psychoanalysis in conjunction with medication: a clinical research opportunity

The increasingly common practice of introducing medication into the analytic relationship is of practical and theoretical concern to analysts. Pharmacological agents and their somatic effects, it is argued, may be seen as a research equivalent to brain lesions, long favored tools in correlating brain with mind function, while psychoanalytic process data may be seen as a fine-tuned instrument for studying the subjective and emotional processes that reflect the underlying brain effect. A method of naturalistic study of psychoanalytic process both with and without a psychopharmacological agent is described and illustrated in two patients. The potential of this method for providing data useful in understanding the mechanism of action of psychoactive medications and of individual variations in response is explored. Both patients, treated with stimulant for ADHD, showed striking differences in self- and object representation, defense, affect, and cognition that correlated with analytic periods on and off the medication. The implications of these observations for understanding both the action of the medication and the fundamental functional disruptions in the condition are explored as well.     

Development of differences in response latencies to right and left visual fields

Robust lateralization developed in right-handed adults who were asked to judge letter pairs as "same" or "different" during 4608 trials. By the end of the first two blocks (768 trials) "same" responses were favored when presented in the RVF (transmitted directly to the left hemisphere) and "different" responses were favored when presented in the LVF (transmitted direction to the right hemisphere). This gradually reversed over sessions with "same" responses becoming faster for letters presented in the LVF, and "different" responses becoming faster for stimuli presented in the RVF. The laterality acquired under these conditions was cumulative and reproducible, appeared in all 16 subjects, and was preserved between sessions a week apart. The data suggest that laterality is a flexible and reversible characteristic of the human brain even when stimulus and task remain constant.     

Exploring the Emotional Side of Job Search Behavior for Younger Workforce Entrants

Using a sample of 332 younger (ages 18–23) workforce entrants broken into subsamples, Study 1 found empirical support for 2 distinct types of job search behavior, detached and interactive. These 2 dimensions seemed to represent different levels of emotional involvement in the job search process. Significant correlates for each dimension of job search behavior were found. Using a separate sample of 117 working college students, Study 2 found that extroverted individuals favored interactive job search behaviors, whereas introverted individuals favored detached job search behaviors. The implications of these results are discussed and future areas of research are identified.     

ERRORLESS LEARNING: REINFORCEMENT CONTINGENCIES AND STIMULUS CONTROL TRANSFER IN DELAYED PROMPTING

Delayed prompting can produce errorless discrimination learning. There is inherent in the procedure a disparity in reinforcement density which favors unprompted over prompted responses. We used three schedules of reinforcement to investigate the impact of reinforcement probability on transfer of stimulus control. One schedule of reinforcement was equal prior to and following a prompt (CRF/CRF), the second favored unprompted responses (CRF/FR3), and the third favored responses following the prompt (FR3/CRF). Experimental questions concerned the probability of errors, the probability of transfer, and the rate of transfer in the context of delayed prompting. Transfer was accelerated when reinforcement probability favored anticipatory responding. The schedule that favored prompted responses did not prevent a shift to unprompted responding. Errors were infrequent across procedures. Reinforcement probability contributes to but does not entirely determine transfer of stimulus control from a delayed prompt.     

Effects of neocortical ectopias and environmental enrichment on Hebb-Williams maze learning in BXSB mice

Approximately 40-60% of BXSB mice have neocortical ectopias, a developmental anomaly characterized by migration of neurons into the neuron-sparse layer I of cortex. Previous studies have shown that ectopic BXSB mice have superior reference, but inferior working, memory on spatial tasks. Female BXSB mice were housed either in an enriched environment or in standard cages at weaning. Subsequently, these animals were tested on four of the Hebb-Williams mazes in a water-based version of this maze. Theoretically, two of the maze configurations placed greater emphasis on reference memory to find the goal, whereas the other two favored working memory. Ectopics reared in standard housing conditions were better than nonectopics on mazes that favored the use of reference memory, but poorer on mazes that favored working memory. In contrast, subjects raised in the enriched environment showed no ectopia differences. A comparison of enriched and standard housing conditions found that the enriched animals had better reference memory but poorer working memory. The latter effect may be because the enriched environment, although more stimulating, did not change in time or space; and other researchers have shown that daily replacement of stimuli in complex environments is correlated with better working memory.     

Productive conflict in group decision making: genuine and contrived dissent as strategies to counteract biased information seeking

Decision-making groups in organizations are often expected to function as a “think tank” and to perform “reality testing” to detect the best alternative. A biased search for information supporting the group's favored alternative impairs a group's ability to fulfill these requirements. In a two-factorial experiment with 201 employees and managers from various economic and public organizations, genuine and contrived dissent were investigated as counterstrategies to biased information seeking. Genuine dissent was manipulated by forming three-person groups whose members either all favored the same alternative individually (homogeneous groups) or consisted of a minority and a majority faction with regard to their favored alternative (heterogeneous groups). Contrived dissent was varied by the use or nonuse of the “devil's advocacy” technique. The results demonstrate that heterogeneity was more effective in preventing a confirmatory information-seeking bias than devil's advocacy was. Confidence was identified as an important mediator. Implications for the design of interventions aimed at facilitating reality testing in group decision making are discussed.     

Framing interethnic ideology: effects of multicultural and color-blind perspectives on judgments of groups and individuals

In 3 experiments, White American college students received a message advocating either a color-blind or a multicultural ideological approach to improving interethnic relations and then made judgments about various ethnic groups and individuals. Relative to a color-blind perspective, the multicultural perspective led to stronger stereotypes, greater accuracy in these stereotypes, and greater use of category information in judgments of individuals. This increase in between-category differentiation occurred both for attributes that favored the in-group and for attributes that favored the out-group and was also paired in some cases with greater overall positivity toward the out-group. The findings lead us to question the implicit assumption driving the majority of social psychological efforts at prejudice reduction: that the categorization process leads to prejudice, and that the relevance of social categories must therefore be de-emphasized.     

Why do aggressive movies make people aggressive? an attempt to explain short-term effects of the depiction of violence on the observer

An explanation-approach within the frame of a universal and integrating theory of aggression is favored for understanding the effects of exposure to violence. Kornadt's Motivation Theory of Aggression is used to generate several hypotheses concerning the effects of aggressive movies on a viewer's expectancy-value-cognitions and these are tested in an experiment. The experiment suggests that aggressive stimulation is able to change aggression-related expectancy-value-cognitions in an aggression-facilitating direction. Based on these results, an attempt is made to explain increases in the aggression of viewers in terms of the Motivation Theory of Aggression. © 1993 Wiley-Liss, Inc.     

Brutality of assault in political cartoons affecting humor appreciation

Political cartoons depicting a presidential candidate undergoing an aggressive assault were manipulated to assess the effect on humor appreciation of variations in the degree of brutality of the aggressive tactics (minimal, intermediate, extreme). The identity of the depicted candidate (Richard Nixon vs George McGovern) was also manipulated. Humor-appreciation ratings were given to these cartoons by student subjects during the week preceding the 1972 presidential elections. Attitudes toward the depicted candidates were assessed in a postexperimental questionnaire. Neither degree of brutality nor affect toward the victim exerted a significant main effect, but a significant transverse interaction between the two variables was observed. When the assault involved minimal levels of brutality, the victimization of a rejected candidate was appreciated significantly more than that of a favored one; when intermediate levels of brutality were depicted, assaults against rejected candidates did not differ appreciably from attacks upon favored candidates in the level of mirth they elicited; when the brutality was extreme, aggression against rejected candidates was appreciated less than assaults against favored candidates, although nonsignificantly so. Of the various theoretical notions which were advanced to predict the results, a rationale involving the decoder's motivation to favor or object to the manner in which the aggressive agent is characterized as well as his motivation to enjoy or dislike the communication's projected outcome was considered to account best for the findings.     

Sex Differences in Mathematics Components of the Iowa Tests of Basic Skills

The Mathematics Problem Solving (MRS) and Mathematics Concepts (MC) subtests of the Iowa Tests of Basic Skills were investigated for content and psychometric item bias at grades 3, 6, and 8. A small proportion of items were identified in each subtest which significantly favored either males or females. No skill classification, item content or location trends could be found for the mathematics subtests at each grade level. Across the grade levels, items in the MC subtest favored males for grades 3 and 6, but females were favored at grade 8. The procedure used in the study is generalizable to other groups (minority or grade levels). Test consumers have the right to know whether the test they use is fair for selected groups of students. Results from empirical investigations should appear in the Test Manual that accompanies the test battery.     

Which way is upright and normal? Haptic perception of letters above head level.

In three experiments, the perception of the apparent orientation of block letters shown in various orientations above the subject's head in the horizontal plane was examined. A block letter F with its front facing down toward the observer has two crossbars on its right side; the top is the part with the long crossbar, and the base has no bar. The experiments involved changing the locations of these parts with respect to the observer. In Experiment 1, the subjects using touch most often identified a letter as having its left and right sides in a normal orientation if the front of the block letter faced upwards away from the observer, with the bar on the right and the top of the letter farther from the subject than the letter's base. In Experiment 2, the subjects judging visual uprightness favored positions in which the bars were on the right, the top of the block letter was near them, and the letter's front faced downwards toward the observer. In Experiment 3, the subjects using touch most often assessed letters as being upright if the top of the letter was the farthest part and the bar was on the right. The results suggest that, when assessing orientation, subjects using touch favored positions that would be reached by a letter moving vertically upwards from table height, but subjects relying on vision favored positions reached by a letter moving in an are centered on the subject's head (on the eyes, in particular).     

The Impact of Job Applicants' Facial Maturity, Gender, and Academic Achievement on Hiring Recommendations

Two studies investigated the impact of job applicants' facial maturity, gender, and achievement level on hiring recommendations. The results revealed that discrimination based on gender and facial appearance varies with the type of job for which an applicant is being considered. Applicants who were babyfaced or female were favored for jobs requiring qualities of warmth and submission, whereas those who were maturefaced or male were favored for jobs requiring qualities of shrewdness and leadership. These hiring preferences were most pronounced for high achieving applicants. They were also paralleled by stereotypical perceptions of the job- relevant attributes possessed by the applicants, which suggests that the effects of applicants' gender and facial maturity are mediated by the perceived fit between their assumed attributes and the job requirements. Finally, the jobs for which male and maturefaced applicants were favored were those for which high-achieving applicants were also favored, which suggests that female and babyfaced applicants are most apt to be discriminated against when applying for higher status jobs.     

Prime elements of subjectively experienced feelings and desires: imaging the emotional cocktail

Primary affects exist at an ecological-communicative level of analysis, and therefore are not identifiable with specific brain regions. The constructionist view favored in the target article, that emotions emerge from "more basic psychological processes," does not specify the nature of these processes. These more basic processes may actually involve specific neurochemical systems, that is, primary motivational-emotional systems (primes), associated with specific feelings and desires that combine to form the "cocktail" of experienced emotion.     

Comparing the adaptabilities of Brazilian adolescent students and adult workers

Many studies have verified the validity of the Career Adapt-Abilities Scale in diverse samples, both adolescents and adults. However, which abilities are more typical of each group remains unknown. This study investigated the CAAS factorial structure with Brazilian adolescents, to verify differences between adolescents and adults and to explore the occurrence of differential item functioning analysis (DIF), by considering these two groups as independent variables. The two Brazilian samples were composed by adolescents (n = 272) and by adult workers (n = 404). Results confirmed the expected factorial structure in the adolescents sample and that adults scored higher on all CAAS factors. DIF analysis identified more items favored adults, as expected, but there was coherence in item content which favored each group. Nevertheless, there is no psychometric evidence supporting the need for different forms of CAAS for each group. Results are discussed by taking into account the practical implications of the findings.     

The Direct and Indirect Effects of Inadmissible Evidence1

College students (N= 270) assigned to six-person mock juries read summaries of a murder trial and then evaluated the defendant's guilt both before and after group discussion. The strength of the prosecution's case was manipulated, as was the inclusion of extra wiretapping evidence that favored the prosecution or the defense and was ruled admissible or inadmissible by the judge. Whether it favored the prosecution or the defense, inadmissible evidence directly biased subjects' reactions toward the defendant and indirectly biased their behaviors during the group discussions. None of these effects varied with the strength of the prosecution's case. The results also showed that the direct effects of inadmissible evidence were at least partially mediated by its indirect effects, suggesting that the process of deliberation can potentially help jurors to control the influence of inadmissible evidence on their decisions.
