Factors Affecting the Psychodiagnostic Significance of Color Perception

50 males, 17 and 18 years of age, and their natural parents were given the Blacky Defense Preference Inventory to determine if there are commonalities of defense preferences within families and within sex groups.

The results tended to support the hypothesis that male adolescents manifest defense preferences more similar to those of their father than to nonrelated adult males but failed to support a comparable hypothesis concerning the adolescent's similarity of defense preferences to his mother versus nonrelated adult females. The adolescent males did not reveal defense preferences more similar to those of their father than of their mother nor were sex differences in defense preferences observed. An additional finding suggested that the adult males are more heterogeneous in their defense preferences than are adult females.     

Interplay Between Service Era,PTSD Symptom Expression,and Treatment Completion Among Veterans

The current veteran population has grown significantly as a result of 3 recent major conflicts: Vietnam, Persian Gulf War, and Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF). Despite a strong presence in VA PTSD specialty clinics nationwide, little is known about how these veteran cohort groups differ in PTSD symptom presentation. Additionally, it is unclear how variations in PTSD symptom presentation may in turn affect treatment adherence and completion. Understanding factors associated with treatment dropout from exposure-based therapy for PTSD is an important area of study, as individuals who drop out of treatment are likely to remain symptomatic and experience significant impairment across a number of psychosocial domains. The present study examined the relationship between service theater affiliation and pretreatment symptom expression as predictors of treatment completion in a sample of 164 veterans. Although treatment completion did not differ by service era, study data revealed statistically significant differences in initial PTSD symptom expression. Implications of the results and future directions are discussed.     

Causal Attributions Predict Willingness to Support the Allocation of Funding to Lung Cancer Treatment Programs

Lung cancer patients may experience stigmatization as a result of the link between their disease and smoking, such as lack of public support for funding lung cancer treatment programs. This study examines whether causal attributions for the contraction of lung cancer predict the stigmatization of individuals with the disease by investigating willingness to support the allocation of funds to hypothetical lung cancer treatment programs. Participants were 766 undergraduate students. The findings indicate that participants who made causal attributions preferred to support the allocation of funding to programs that value the lives of breast cancer patients, rather than lung cancer patients. These findings have implications for understanding the influence of causal attributions on the stigmatization of lung cancer.     

Sleep-dependent consolidation of procedural motor memories in children and adults: the pre-sleep level of performance matters

In striking contrast to adults, in children sleep following training a motor task did not induce the expected (offline) gain in motor skill performance in previous studies. Children normally perform at distinctly lower levels than adults. Moreover, evidence in adults suggests that sleep dependent offline gains in skill essentially depend on the pre-sleep level of performance. Against this background, we asked whether improving children's performance on a motor sequence learning task by extended training to levels approaching those of adults would enable sleep-associated gains in motor skill in this age group also. Children (4-6 years) and adults (18-35 years) performed on the motor sequence learning task (button-box task) before and after ~2-hour retention intervals including either sleep (midday nap) or wakefulness. Whereas one group of children and adults, respectively, received the standard amount of 10 blocks of training before retention intervals of sleep or wakefulness, a further group of children received an extended training on 30 blocks (distributed across 3 days). A further group of adults received a restricted training on only two blocks before the retention intervals. Children after standard training reached lowest performance levels, whereas in adults performance after standard training was highest. Children with extended training and adults after reduced training reached intermediate performance levels. Only at these intermediate performance levels did sleep induce significant gains in motor sequence skill, whereas performance did not benefit from sleep in the low-performing children or in the high-performing adults. Spindle counts in the post-training nap were correlated with performance gains at retrieval only in the adults benefitting from sleep. We conclude that, across age groups, sleep induces the most robust gain in motor skill at an intermediate pre-sleep performance level. In low-performing children sleep-dependent improvements in skill may be revealed only after enhancing the pre-sleep performance level by extended training.     

PUTTING PRESUPPOSITIONS ON THE TABLE: WHY THE FOUNDATIONS MATTER

Abstract. Over time scientists have developed an effective investigative process that includes the acceptance of particular basic presuppositions, methods, content, and theories. The deeply held presuppositions are the philosophical foundation of scientific thought and do much to define the field's worldview. These fundamental assumptions can be esoteric for many and can become a source of conflict when they are not commonly shared with other points of view. Such presuppositions affect the observations, the conclusions drawn, and the positions taken. Furthermore, in some cases presuppositions in science have undergone important shifts in meaning, causing an increasing dissonance. We argue that disputes in religion and science often are due to these very basic differences in philosophy that are held by members in the different communities. To better understand the nature of science and its differences with religious views, presuppositions rather than conclusions should be articulated and examined for validity and scope of application.     

Fear of AIDS: Its meaning and implications for clinical practice

Clinical reports have appeared about patients who present for mental health treatment with the major symptom of fearing that they have AIDS. The clinical reports of patients who fear AIDS are similar to those made many years ago by patients who feared syphilis. As with the syphilophobia of years ago, the AIDS group represents a divergent set of patients. Some can be described as the worried well who have realistic concerns because of a recent history of high risk behavior; others have unrealistic fears that are secondary to a major mental disorder such as hypochondriasis, depression, or schizophrenia. Suggestions are made to psychotherapists who encounter patients presenting with the problem of fearing AIDS.The views expressed here do not necessarily represent those of the Pennsylvania Psychological Association     

Spectral indices of cardiovascular adaptations to short-term simulated microgravity exposure

We investigated the effects of exposure to microgravity on the baseline autonomic balance in cardiovascular regulation using spectral analysis of cardiovascular variables measured during supine rest. Heart rate, arterial pressure, radial flow, thoracic fluid impedance and central venous pressure were recorded from nine volunteers before and after simulated microgravity, produced by 20 hours of 6° head down bedrest plus furosemide. Spectral powers increased after simulated microgravity in the low frequency region (centered at about 0.03 Hz) in arterial pressure, heart rate and radial flow, and decreased in the respiratory frequency region (centered at about 0.25 Hz) in heart rate. Reduced heart rate power in the respiratory frequency region indicates reduced parasympathetic influence on the heart. A concurrent increase in the low frequency power in arterial pressure, heart rate, and radial flow indicates increased sympathetic influence. These results suggest that the baseline autonomic balance in cardiovascular regulation is shifted towards increased sympathetic and decreased parasympathetic influence after exposure to short-term simulated microgravity.     

EVOLUTION,CONTINGENCY, AND CHRISTOLOGY

Christopher Southgate has made important contributions to theodicy and the theory of divine action in light of the contingency in evolution and the suffering of creation. What happens then when one thinks through the implications of contingency for Christology? One can admit that aesthetic and moral judgments are products of a contingent history and yet affirm that they really are valid. Similarly, we argue, one can acknowledge the contingency of Jesus’ existence, actions, and subsequent impact and still maintain that his will was uniquely united with the divine will. Following a critical engagement with the recent work of Keith Ward, we argue that a high Christology is compatible with the actual contingencies of evolutionary and social history, without the necessity of interventionist divine action.     

Contributions to the history of psychology: CXVII. Who's who in American psychology: a citation study of introductory psychology textbooks

The author indexes of 15 introductory psychology textbooks were surveyed to identify the authorities cited most frequently. The five names cited most often in descending order were Freud, Bandura, Skinner, Piaget, and James. Differences from earlier comparable citation studies are discussed.     

Child abuse: Prognostic factors in therapy effectiveness

We have attempted to define the problem of child abuse by separating the abusers into two categories. Pattern abusers seem to be primarily a social issue in that the abuse is an outgrowth of the parental charge to control her/his child. However, another abuser is seen as a borderline or psychotic individual when the abuse is an outgrowth of a transferential distortion on the part of the parent. It was suggested that family therapy for the latter may be the preferential mode of intervention.
