Perspectives on multisensory experience and cognitive development in infants with cochlear implants

Infants learn about their environment through sensory exploration, acquiring knowledge that is important for cognitive development. However, little is known about the sensory exploration of infants with profound hearing loss before or after they receive cochlear implants. This paper reviews aspects of sensory perception and cognitive development in hearing infants, discusses the implications of delayed access to auditory information for multisensory perception and cognitive development in infants who use cochlear implants, and suggests several new directions for research addressing multisensory exploration and cognitive development in infants with cochlear implants.     

RECRUITERS' USE OF GPA IN INITIAL SCREENING DECISIONS: HIGHER GPAs DON'T ALWAYS MAKE THE CUT

The relationship between college grade point average (GPA) and recruiters' initial screening decisions was examined using data from 548 job postings in a college recruitment program. Results indicate that in-major grade point average (GPA) is more strongly associated with screening decisions ( p = 0.18, SD_P = 0.200) than is overall GPA ( p = 0.06, SD_P = 0.187), but the magnitudes of the relationships varied across decision sets including a larger number of negative values than would be expected from sampling error alone. Subsequent examination of the bivariate data identified 6 different plot types suggesting that recruiters use a variety of GPA decision rules to initially screen applicants in college recruiting. The most common data plots found in 42% of the decision sets suggests that recruiters do not use GPA in screening decisions. But a surprising 81 of 548 decision sets indicated recruiters selected against applicants with high GPAs. Evidence that organizations recruiting for the same job produced different plot types suggests that the use of GPA data in initial screening decisions may be idiosyncratic to individual recruiters.     

Beliefs And Creative Performance: Relationships Across Three Tasks

Creative work occurs on novel, ill‐defined tasks. By virtue of their ambiguity and complexity, however, creative tasks allow the situation to be construed in a number of ways. Accordingly, one might argue that beliefs, as interpretive structures, would be related to performance on creative problem‐solving tasks. To test this proposition, a battery of measures was developed to assess people's beliefs. Subsequently, 195 undergraduates were asked to work on three creative problem‐solving tasks. When quality and originality ratings, reflecting performance on the creative problem‐solving tasks, were regressed on the beliefs, multiple correlations in the low .40s were obtained. It was found that beliefs consistent with the nature of the task were those most likely to be related to performance. The implications of these findings are discussed with respect to the role of beliefs in shaping people's creative problem‐solving activities.     

Emotional Reactions While Watching Graphic Medical Procedures: Vocational Differences in the Explicit Regulation of Emotions1

We examined the role of occupation in how people regulate emotional responses. Graduate nursing students were compared to undergraduate psychology students on self‐reported emotional reactions to videos depicting graphic medical procedures. Skin conductance was also recorded. Overall, nursing students reported less disgust and fear, but more sadness while watching the clips, compared to psychology students. The 2 groups did not differ in skin conductance activity when watching a video with no specific instructions. When instructed to suppress or reappraise their emotional reactions to the videos, however, the psychology students showed increases in skin conductance arousal, whereas the nursing students did not. The results are discussed within the context of research on strategies to regulate one's emotions in the workplace.     

NEWTON AND PROCLUS: GEOMETRY,IMAGINATION, AND KNOWING SPACE

I aim to clarify the argument for space that Newton presents in De Gravitatione (composed prior to 1687) by putting Newton's remarks into conversation with the account of geometrical knowledge found in Proclus's Commentary on the First Book of Euclid's Elements (ca. 450). What I highlight is that both Newton and Proclus adopt an epistemic progression (or “order of knowing”) according to which geometrical knowledge necessarily precedes our knowledge of metaphysical truths concerning the ontological state of affairs. As I argue, Newton's commitment to this order of knowing clarifies the interplay of the imagination and understanding in geometrical inquiry and illuminates how geometrical knowledge of space can lead to knowledge that space depends on and is related to God. In general, appreciating the Proclean elements of Newton's argument brings added light to the significance of geometrical inquiry for his general natural philosophical program and grants us insight into the philosophical grounding for the notion of absolute space that is presented in the Principia mathematica (1687).
