Shared Moral and Spiritual Development Among Human Persons and Artificially Intelligent Agents

Technical advances in artificial intelligence make somewhat likely the possibility of robotic or software agents exhibiting or extending human-level intelligence within a few decades. Theological investigation can help meet significant research goals in artificial intelligence by orienting the development of agent communication and moral reasoning toward a shared moral and spiritual development of human persons and intelligent agents. In particular, Josiah Royce’s Loyalty-to-Loyalty initiates a moral stance within which humans and intelligent agents can develop constructive ethical frameworks and his semiotic philosophy of community can guide the development and functioning of an agent’s interpretive processes and can model shared spiritual formation.     

A discussion of modern versus traditional psychometrics as applied to personality assessment scales

Item response theory (IRT) methods are used by large testing firms, state agencies, and school districts to construct, analyze, and score most major aptitude, achievement, proficiency, entrance, and professional licensure exams. Personality assessment, in contrast, has not generally adopted these more powerful, modern psychometric techniques. We evaluate the possible role of IRT in the personality domain by highlighting key areas in which IRT and traditional methods differ. Although we conclude that IRT has a significant role to play in future personality measurement, there are many systemic and technical barriers to its routine application.     

Sleep deprivation selectively impairs memory consolidation for contextual fear conditioning

Many behavioral and electrophysiological studies in animals and humans have suggested that sleep and circadian rhythms influence memory consolidation. In rodents, hippocampus-dependent memory may be particularly sensitive to sleep deprivation after training, as spatial memory in the Morris water maze is impaired by rapid eye movement sleep deprivation following training. Spatial learning in the Morris water maze, however, requires multiple training trials and performance, as measured by time to reach the hidden platform is influenced by not only spatial learning but also procedural learning. To determine if sleep is important for the consolidation of a single-trial, hippocampus-dependent task, we sleep deprived animals for 0–5 and 5–10 h after training for contextual and cued fear conditioning. We found that sleep deprivation from 0–5 h after training for this task impaired memory consolidation for contextual fear conditioning whereas sleep deprivation from 5–10 h after training had no effect. Sleep deprivation at either time point had no effect on cued fear conditioning, a hippocampus-independent task. Previous studies have determined that memory consolidation for fear conditioning is impaired when protein kinase A and protein synthesis inhibitors are administered at the same time as when sleep deprivation is effective, suggesting that sleep deprivation may act by modifying these molecular mechanisms of memory storage.     

Forward inference using functional neuroimaging: dissociations versus associations

Many people are excited by functional neuroimaging as a new tool for cognitive science; many others are sceptical. In this opinion article, I describe a 'forward inference' that one can make from patterns of brain activity to distinguish between cognitive theories. I give an example of forward inferences in research on recognition memory, and outline some statistical criteria for a 'qualitative difference' in brain activity. Forward inferences resemble the dissociation logic long-used in behavioural studies of healthy and brain-damaged people, although I argue that dissociations in neuroimaging data can go beyond behavioural dissociations. Nonetheless, forward inferences are only as good as the cognitive theories to which they pertain, and are most valuable in conjunction with other types of inference.     

Masking by object substitution: dissociation of masking and cuing effects

In a newly discovered form of visual masking, a target stimulus is masked by 4 flanking dots if their offset is delayed relative to the target (V. Di Lollo, J. T. Enns, & R. A. Rensink, 2000). In Di Lollo et al. (2000), the dot pattern also cued the relevant target and therefore required deliberate attention. In the present Experiments 2-6, a central arrow cued 1 of 2 letters for an E/F discrimination, with dots flanking both letters. Masking was reduced compared with the mask-cue procedure but was still robust. Delayed-offset dots flanking the nontarget also impaired performance, indicating competition for attention. Masking was unaffected by brightness of the dots relative to the target. Masking was attenuated not only by precuing attention to the target location but also by preview of an uninformative dot mask. Theories of masking by object substitution must therefore accommodate the prior context into which the target stimulus is introduced.     

Are creativity and schizotypy products of a right hemisphere bias?

Prior research has shown associations between higher creativity (e.g., semantic association, verbal fluency), higher schizotypy (e.g., magical ideation), and relatively stronger right hemisphere laterality measures--when each of the three pairings has been studied individually. Our prior study related creativity and schizotypy to signal detection theory response criterion aspects of laterality. The present study attempted to integrate findings regarding these three constructs and to replicate the signal detection theory laterality results by providing measures of all three constructs in a within subjects design. Participants were 60 undergraduates who completed a test battery including two measures of creativity, three measures of schizotypy, a lateralized lexical decision task, and a dichotic listening task. Results are consistent with individual differences in creativity and schizotypy being partly related to a response criterion favoring right hemisphere, possibly nonconscious, processing. Dichotic listening results revealed a strong association of better right hemisphere (left ear) localization ability and creativity.     

Who Is This God of Whom You Speak? Counseling Students' Concept of God

Many clients bring a belief in God or a Higher Power into counseling sessions. What is less clear, however, is how counselors conceptualize “god,” which may affect how spirituality is integrated in the counseling process. To explore this question, the authors conducted a concept map study of god images among counseling students. Results suggest that students harbor broad and diverse conceptualizations of god, which may affect the counseling process.
