Computer software and hardware to determine contrast sensitivity using three methods: Tracking,limits, and constant stimuli

The software and hardware to obtain contrast sensitivity functions in a single session with monkeys are described. The versatility of the software allows the program to be used in a variety of sensory systems with only minor programming modifications. It will permit absolute or difference threshold measurements with any one of three methods of threshold testing: (1) method of tracking, (2) method of limits, and (3) method of constant stimuli. Human and monkey contrast sensitivity functions measured with the software and hardware are provided.     

Facial identity and facial speech processing: Familiar faces and voices in the McGurk effect

An experiment was conducted to investigate the claims made by Bruce and Young (1986) for the independence of facial identity and facial speech processing. A well-reported phenomenon in audiovisual speech perception—theMcGurk effect (McGurk & MacDonald, 1976), in which synchronous but conflicting auditory and visual phonetic information is presented to subjects—was utilized as a dynamic facial speech processing task. An element of facial identity processing was introduced into this task by manipulating the faces used for the creation of the McGurk-effect stimuli such that (1) they were familiar to some subjects and unfamiliar to others, and (2) the faces and voices used were either congruent (from the same person) or incongruent (from different people). A comparison was made between the different subject groups in their susceptibility to the McGurk illusion, and the results show that when the faces and voices are incongruent, subjects who are familiar with the faces are less susceptible to McGurk effects than those who are unfamiliar with the faces. The results suggest that facial identity and facial speech processing are not entirely independent, and these findings are discussed in relation to Bruce and Young’s (1986) functional model of face recognition.

EXPERIENCED HIRING VERSUS COLLEGE RECRUITING: PRACTICES AND EMERGING TRENDS

Although much professional and managerial hiring involves experienced workers, previous recruitment research has focused almost exclusively on new college graduates. To remedy this imbalance, 251 staffing professionals were surveyed concerning experienced-versus-college hiring practices in their organizations. Results suggest that a majority of positions requiring a college degree are filled with experienced workers. Experienced hires are evaluated more highly than new graduates on most characteristics (understanding business, knowledge of competition, realistic expectations, technical skills, interpersonal skills, writing skills, work ethic, likelihood of success, personal ethics), although new graduates are evaluated more highly on open-mindedness and willingness and ability to learn new things. Higher proportions of experienced hiring are associated with organizational growth, short-term staffing strategies, older workforces, and less dynamic business environments. Perceived success of experienced hiring is associated with greater use of effective recruitment sources, older workforces, and more competitive salary offers.     

A mere exposure effect for transformed three-dimensional objects: Effects of reflection, size, or color changes on affect and recognition

If the mere exposure effect is based on implicit memory, recognition and affect judgments should be dissociated by experimental variables in the same manner as other explicit and implicit measures. Consistent with results from recognition and picture naming or object decision priming tasks (e.g., Biederman & E. E. Cooper, 1991, 1992; L. A. Cooper, Schacter, Ballesteros, & Moore, 1992), the present research showed that recognition memory but not affective preference was impaired by reflection or size transformations of three-dimensional objects between study and test. Stimulus color transformations had no effect on either measure. These results indicate that representations that support recognition memory code spatial information about an object’s left-right orientation and size, whereas representations that underlie affective preference do not. Insensitivity to surface feature changes that do not alter object form appears to be a general characteristic of implicit memory measures, including the affective preference task.     

Correlation between Changes in Stress-Induced Corticosterone Secretion and GR mRNA Levels

The current study was conducted to determine the potential relationship between stress-induced corticosterone secretion and corticosteroid receptor mRNA levels after 5 days of intermittent stress. In particular, we were interested in the rate at which animals terminate a stress response, and how this termination may be altered by repeated stress. Adult male Sprague-Dawley rats were subjected to either 5 days of restraint stress or 5 days of an unpredictable stress paradigm. Restraint-stress induced corticosterone secretion was measured on Days 1 and 5 in both groups, and animals were killed on Day 6. Glucocorticoid receptor (GR), and mineralocorticoid (MR) mRNA levels were determined using in-situ hybridization techniques. Five days of restraint stress caused an habituation of the plasma corticosterone response to stress measured 60 and 90 min post-stress initiation; this pattern of corticosterone secretion was not observed in the animals subjected to unpredictable stress. Five days of either stress paradigm did not alter MR mRNA levels measured within the hippocampus or GR mRNA levels within the hippocampus or the medial parvocellular division of the paraventricular nucleus of the hypothalamus (mpPVN). However, an individual's GR mRNA levels measured within the CA1/2 region of the hippocampus and the mpPVN were significantly correlated with the degree of habituation of the corticosterone response to stress measured on Day 5. This suggests that an increase in the rate of termination of the stress response and levels of GR within the hippocampus and mpPVN may be functionally related.     

The Adam and Eve syndrome

Conclusion The concept of divine forgiveness is incomprehensible to most, since it involves principles that defy rational interpretation on the level of human cognition. As a result, individuals, and especially those who present themselves for treatment, find themselves caught up in a repetition of self-judgment and selfpunishment, which is a reenactment of the original sin and the disobedience encountered in the Garden of Eden. It can be pointed out to patients that this continuous, repetitious acting out of the functions of self-judgment and selfpunishment represents the worst sin of all—the original sin in which the power and authority of God are usurped and assumed, resulting eventually in a denial of God along with symptoms that are often incapacitating. When these functions are returned to God, punishment can be expected to be much less severe and intense, because of the nature and characteristics of divine forgiveness.Ray O.
