Response conflict theory,error rates and hybrid processing: A reply to McLeod

McLeod (1977) has proposed a parallel processing model of the psychological refractory period quite similar to an earlier model most recently adumbrated by Kantowitz (1974a). This article corrects some erroneous statements made by McLeod about the testability of the response conflict model and emphasizes the importance of error data in distinguishing among conceptually similar models of the PRP effect.     

The extra credit effect in interpersonal attraction

An experiment was conducted in which three levels of personal evaluation (positive, mixed, or negative) were crossed with two levels of dependence of the evaluator (high or low) and two levels of accuracy of the evaluation (high or low). Liking for the evaluator was expected to increase linearly with the favorableness of the evaluation, with two possible exceptions: When a positive evaluation from a dependent evaluator was inaccurate, and when a negative evaluation from a dependent evaluator was accurate. In the former case, the obvious inaccuracy of the positive evaluation in the face of the temptation to ingratiate was expected to elicit a decrement in liking (an “ingratiation effect”) by the person being evaluated. In the latter case, the honesty of the evaluator in the face of the temptation to ingratiate was expected to elicit an increment of linking (an “extra credit effect”) by the person being evaluated. Only the second of these two possibilities was supported.     

Increasing and decreasing intrinsic interest with contingent rewards: A test of cognitive evaluation theory

The study examined Deci's (Deci, E. L. Intrinsic motivation. New York: Plenum Press, 1975) hypotheses regarding the effects of contingent rewards on intrinsic task interest. Seventy-two male university students worked on a series of puzzles and were given either a high value reward ($1.50) or a low value reward ($.45). The money was given either contingent upon the simple execution of the task (task-contingent), contingent upon the ostensible attainment of a performance criterion level (criterion-contingent), or noncontingent and unexpected (control). Compared to the high payment control subjects, subjects who received the task-contingent high reward rated the task as less interesting, while subjects who received the criterion-contingent high reward rated it as more interesting. Also, subjects expressed less interest in the task after receiving the high task-contingent reward than the low task-contingent reward, but indicated greater interest after receiving the high criterion-contingent reward than the low criterion-contingent reward. It was concluded that substantial support was obtained for Deci's (1975) cognitive evaluation theory.     

A Plumber's friend in need is a Plumber's friend indeed

In response to the critique of Gaes, Quigley-Fernandez, and Tedeschi (Journal of Research in Personality, 1978, 12, 189–192) it was acknowledged that the cell Ns were incorrect as originally reported, and the weakness of a postexperimental division of subjects was reaffirmed. Emphasis was placed on the comparability of a simple rating scale and an elaborate bogus pipeline in measuring attraction. The need for determining the way in which the bogus pipeline functions prior to its uncritical adoption in any given experimental situation was stressed as a point of agreement.     

Speech dominance and handedness in the normal human

Spectral analysis was used to measure the coherence or similarity of form between occipital and temporal evoked potentials. In both right- and left-handers, coherence was greater in the left hemisphere for click stimuli and in the right hemisphere for flash stimuli. Similar asymmetries occurred in left but not right speech dominant patients whose speech lateralization has been determined by the intracarotid amytal test. Right-handers and males, however, showed significantly larger amplitudes of auditory responses in the right hemisphere. Left-handers and females reversed this pattern. It was concluded that within a basically left speech dominant organization, males and right-handers would emphasize the verbal, temporal structure of auditory information and the nonverbal, spatial structure of visual information. Females and left-handers would tend to reverse this emphasis.     

A Test of Contextual Theory: The Relationship Among Relational Ethics,Marital Satisfaction,Health Problems,and Depression

Few studies have examined the theoretical underpinning of contextual theory. Using structural equation modeling, the relationship among relational ethics (recognized as the most important aspect of contextual theory), marital satisfaction, depression, and illness was examined. Data came from a national sample of 632 mid-life, married individuals. Results supported Nagy’s contextual theory. The total score of the Relational Ethics Scale was a significant predictor of marital satisfaction, and marital satisfaction was significantly associated with depression and health problems. Vertical and horizontal subscales of relational ethics also were significant predictors of depression and health problems through the mediating variable of marital satisfaction.     

Stresses reported by UK trainee counselling psychologists

This study examined stressors and psychological distress in 109 UK counselling psychology trainees. The research focus was two-fold. What is the profile of stressors that counselling psychology trainees report about the components of training? What relationship is there between this profile, and other characteristics of trainees, including their level of current psychological distress? Data from a stress survey and from the General Health Questionnaire were examined. High stress scores were found on three aspects of the stress survey (‘academic’, ‘placements’, ‘personal and professional development’), but not–surprisingly–on the aspect, ‘lack of support systems’. Significant stress differences were reported for gender and age of participants, and highly significant positive relationships were found between General Health Questionnaire and stress scores. Overall, the results suggest actions to be taken. Further research is needed to clarify unavoidable and avoidable stressors in training, and the reduction of trainees’ experience of training stress to the necessary minimum needs to be adopted as an active target by programmes.     

Infant feeding and HIV in Sub-Saharan Africa: what lies beneath the dilemma?

The debate over how to best guide HIV-infected mothers in resource-poor settings on infant feeding is more than two decades old. Globally, breastfeeding is responsible for approximately 300,000 HIV infections per year, while at the same time, UNICEF estimates that not breastfeeding (formula feeding with contaminated water) is responsible for 1.5 million child deaths per year. The largest burden of these infections and deaths occur in Sub-Saharan Africa. Using this region as an example of the burden faced more generally in other resource-poor settings, we contrast the evolution of the clinical standard of care for infant feeding with HIV-infected mothers in high-income countries to the current international clinical guidelines for HIV-infected mothers and infant feeding in resource-poor settings. While the international guidelines of exclusive breastfeeding for a 6-month period seem to offer the least-worst strategy for reducing mother-to-child transmission of HIV during infancy while conferring some immunity through breastfeeding post-6 months, we argue that the impact of the policy on mothers and healthcare workers on the ground is not well understood. The harm reduction approach on the level of health policy translates into a complicated, painful moral dilemma for HIV-positive mothers and those offering them guidance on infant feeding. We argue that the underlying socio-economic disparities that continue to fuel the need for a harm reduction policy on infant feeding and the harm to women and children justify: (1) that higher priority be given to solving the infant feeding dilemma with improved data on safe feeding alternatives, and (2) support of innovative, community-driven solutions that address the particular economic and cultural challenges that continue to result in HIV-transmission to children within these communities.
